However, given the COVID-19 pandemic and the crisis facing our nation and the world, it feels more relevant and important at this moment to discuss the last few weeks and the coming weeks and months ahead of us as a company. Our team is prepared for this challenge and is working hard to effectively manage through this crisis. Our responsibilities to our team, our customers, our shareholders, the communities where we operate, and the environment are our highest priorities and our team has worked diligently to ensure we have a solid crisis management plan and communication strategy. We have set the following goals in order to effectively manage through the COVID-19 crisis: (1) keeping our people safe and healthy; (2) effectively servicing our customers; and (3) maintaining financial discipline. 1. KEEPING OUR PEOPLE SAFE AND HEALTHY We have 2,550 dedicated and talented employees who are the life blood of our company, and it is our priority to keep them safe and healthy. As such, we quickly put standard procedures in place to follow the CDC recommendations for increased social distancing, eliminated meetings of more than 10 people, drastically reduced travel, and increased the cleaning of our facilities and equipment. Our front-line employees (drivers, helpers, mechanics, operators, and recycling sorters) are critical to our efforts to safely manage waste and recycling through this pandemic. Our safety and operating teams collaborated to update our personal protective equipment (PPE) and standard operating procedures for these key employees to reduce their risk of exposure to COVID-19 and to keep our trucks rolling. In addition, we quickly worked to move our back-office employees to work from home to reduce their risk of exposure while providing necessary support for our operating teams. We have effectively leveraged our technology platforms to allow for this transition, while implementing data and systems security and redundancy of functions. We have spent the last two years focused on improving our recruiting practices, on-boarding of new employees, technical training programs, career-paths for advancement, and leadership development. Our focus on attracting, developing, and retaining talent becomes even more critical during a period such as this – where we are only as good as our hard-working employees. 2. EFFECTIVELY SERVICING OUR CUSTOMERS The solid waste industry has been deemed a Critical Infrastructure Industry by the Department of Homeland Security and as an essential service provider by the states in which we operate. The continued operation of the solid waste industry during the pandemic is critical as we work to safely handle customers’ waste and recycling needs and keep their operations and households running. This is especially true where our team works to support doctors, nurses, and other key frontline workers by removing waste from hospitals and medical centers across the northeast. To provide continuity of service for our customers and environmental compliance for our sites, we have established operating contingency plans that can be quickly deployed. We have formed a Priority Response Team (composed of drivers, mechanics, and supervisors) that can mobilize to any of our locations to reduce potential service disruptions. Further, our strong network of operations across the northeast allows for flexibility of service from multiple locations as necessary. In addition, we have been hosting a weekly call with all of our front-line managers in order to effectively communicate in this fast-moving environment. 3. MAINTAINING FINANCIAL DISCIPLINE One of the first steps we took as the crisis first emerged was to establish daily monitoring of key indicators and metrics, including the health of our workforce, service level changes of our customers due to COVID-19, landfill volumes, and changes in expenses. With this information, our team has been able to react quickly to redirect resources, flex variable costs, and freeze discretionary capital expenditures. While roughly 85% of our revenues are generated from stable sources with recurring streams, approximately 15% of our revenues have limited sensitivity to economic declines. As businesses across the country and the northeast have been forced to close temporarily due to state-mandated “shelter-in-place” orders to stop the spread of the COVID-19 virus, we have experienced declines in service revenues, primarily from commercial collection, construction and demolition, and certain landfill volumes. In response, we have flexed key variable operating costs such as third-party transportation and disposal, labor, overtime, fuel, maintenance, and variable general and administrative costs such as incentive compensation to offset a portion of these revenue declines. Over the last 5 years we have progressively improved cash flow generation through our positive pricing programs, operating efficiency programs, and strong capital discipline. We continue to focus on these same areas to maintain solid cash flows through this challenging period. Further, we have maintained a conservative capital structure with adequate liquidity, sufficient debt covenant headroom, and no near-term debt maturities – our next major debt maturity is our Credit Agreement in May 2023. LOOKING FORWARD … While navigating these challenges we remain committed to executing against our 2021 Plan, which focuses on enhancing shareholder returns by improving cash flows and driving profitable growth through the following initiatives: • Increasing landfill returns by driving pricing in excess of inflation in the disposal capacity constrained markets in the Northeast, working to maximize capacity utilization, and advancing key permitting activities. • Driving additional profitability in our collection operations through profitable revenue growth and operational excellence. • Creating incremental value through our resource solutions offerings in our recycling, organics, and customer solutions operations. • Using technology to drive profitable growth and efficiencies through our efforts to update key systems to drive back office transformation, operating efficiencies and salesforce effectiveness. • Allocating capital to balance debt delevering with smart growth through continued capital discipline and selective acquisitions of complementary businesses and assets. Over 15 years ago, we adopted our foundational Core Values (Service, Trust, Responsibility, Integrity, Continuous Improvement, Teamwork) to help guide our team and our company. As we face challenges and uncertainties during the coming weeks and perhaps beyond, I am confident that our Core Values, great team, and leading market positioning will help to guide us through this crisis and position us well for the future. Sincerely, John W. Casella Chairman and Chief Executive Officer April 9, 2020 FORWARD LOOKING STATEMENTS Certain matters discussed in this annual report, including, but not limited to, the statements regarding our intentions, beliefs or current expectations concerning, among other things, our financial performance; financial condition; operations and services; prospects; growth; and strategies, are “forward-looking statements” intended to qualify for the safe harbors from liability established by the Private Securities Litigation Reform Act of 1995.

BUSINESS Overview Founded in 1975 with a single truck, Casella Waste Systems, Inc. is a regional, vertically integrated solid waste services company. We provide resource management expertise and services to residential, commercial, municipal 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 six states: Vermont, New Hampshire, New York, Massachusetts, Maine and Pennsylvania, with our headquarters located in Rutland, Vermont. We have managed operations through four operating segments, including (i) two regional operating segments, which we designate as our Eastern and Western regions, (ii) Recycling, which comprises our larger-scale recycling operations and our commodity brokerage operations and (iii) "Other", which comprises organic services, ancillary operations, along with major accounts and industrial services. Effective January 1, 2020, we reorganized our operating segments as follows: we aligned our organics services and our major account and industrial services with our Recycling segment to form the Resource Solutions segment, thus creating a single resource renewal-focused segment. We also moved our ancillary transportation services, which were previously included in our Other segment, into our Western region. 3 3 Table of Contents As of January 31, 2020, we owned and/or operated 43 solid waste collection operations, 58 transfer stations, 20 recycling facilities, eight Subtitle D landfills, four landfill gas-to-energy facilities and one landfill permitted to accept construction and demolition ("C&D") materials. Strategy Our goal is to build a sustainable and profitable company by providing exemplary service to our customers, while operating safe and environmentally sound facilities. Over the last decade, we have worked with many of our key customers to improve their environmental footprint to meet sustainability goals by increasing their recycling rates, diverting organic materials out of the waste stream into beneficial use processes, and partnering to develop resource solutions within their organizations. Since we first began operating in Vermont in 1975, our business strategy has been firmly tied to creating a sustainable resource management model and we continue to be rooted in these same tenets today. We continue to invest in resources (team, technology, and capital) to further develop this important long-term strategy that we believe will continue to differentiate our service offerings to our customers, make us an employer of choice for our people, and improve our economic returns. We strive to create long-term value for all of our stakeholders, including customers, employees, communities and shareholders. Our primary objective is to maximize long-term shareholder value through a combination of financial performance and strategic asset positioning. Annually, we complete a comprehensive strategic planning process to assess and refine our strategic objectives in the context of our asset mix and the current market environment. This process helps the management team allocate resources to a range of business opportunities with the goal to maximize long-term financial returns and competitive positioning. In early August 2017, we announced an updated long-term strategic plan through our fiscal year ending December 31, 2021 (the “2021 Plan”). The 2021 Plan remains focused on enhancing shareholder returns by improving cash flows and reducing debt leverage through the following strategic initiatives: • • • • • Increasing landfill returns by driving pricing in excess of inflation in the disposal capacity constrained markets in the Northeast and working to maximize capacity utilization. Driving additional profitability in our collection operations through profitable revenue growth and operating efficiencies. Creating incremental value through our resource solutions offerings in our recycling, organics, and customer solutions operations. Using technology to drive profitable growth and efficiencies through our efforts to update key systems to drive back office transformation, operating efficiencies and sales force effectiveness. Allocating capital to balance debt delevering with smart growth through continued capital discipline and selective acquisitions of complementary businesses and assets. To support our efforts, we continue to invest in our employees through leadership development, our career paths program that helps to build long-term development for our employees, technical training for key roles such as drivers and mechanics, and incentive compensation structures that seek to align our employees’ incentives with our long-term goal to improve cash flows and returns on invested capital. Over the last three years we have grown our workforce by approximately 32%, and we believe that continuing to invest in our team and culture are keys to our continued success. Increasing Landfill Returns Disposal capacity continues to tighten in the Northeast market as permanent site closures are reducing capacity and stronger economic and construction activity are driving higher volumes. Given this supply-demand imbalance and the positioning of our assets, we were able to advance disposal pricing by 5.1% (or average price per ton by 7.1%) for the fiscal year ended December 31, 2019 ("fiscal year 2019"). We believe that this positive pricing backdrop will continue as additional site closures are expected over the next several years, and as we reset multi-year contracts we expect to advance pricing in excess of Consumer Price Index on a larger percentage of our inbound waste streams. 4 4 Table of Contents On the landfill development side, we continue to advance key permitting activities across our landfills to increase annual capacity limits at select sites and expand total permitted capacity across our footprint. We have been successful in advancing permit increases at Subtitle D landfills located in Angelica, New York (“Hyland Landfill”), Seneca, New York ("Ontario County Landfill"), Chemung, New York ("Chemung County Landfill"), West Old Town, Maine ("Juniper Ridge Landfill"), Schuyler Falls, New York (“Clinton County Landfill”), Coventry, Vermont ("Waste USA Landfill"), and Campbell, New York (“Hakes Landfill”) over the last four years. Cumulatively, these efforts have added 462 thousand tons per year of permitted capacity and approximately 46.8 million tons of permitted airspace. We have recently been informed by the New Hampshire Division of Environmental Services that it will be necessary to amend our permit application for an additional 1.2 million cubic yards of capacity at the North Country Environmental Services landfill located in Bethlehem, New Hampshire ("NCES Landfill"). This will likely impact the timing of our permit and our results of operations. There can be no assurance that we will receive this permit after it is refiled. Driving Additional Profitability in Collection Operations Collection pricing was up 5.3% for fiscal year 2019, as compared to the fiscal year ended December 31, 2018 ("fiscal year 2018"), with sustained execution against our strategic pricing programs. On the operating side, we continue to advance several key areas, including route optimization, fleet standardization and automation, and maintenance programs to further reduce our operating costs in the collection line-of-business. We are in the fifth year of our comprehensive fleet plan, which is designed to optimize our fleet and target truck replacements to maximize returns, reduce our operating expenses through lower maintenance costs, improve our service levels through reduced down times, and conduct additional automation and optimization of trucks and service types. The combination of these operating advancements and pricing programs are driving improved results in our collection line-of- business, with our cost of operations as a percentage of revenues down approximately (510) basis points from the twelve months ended December 31, 2014 to fiscal year 2019. Creating Incremental Value Through Resource Solutions One of the key objectives of our strategy is to differentiate ourselves in the marketplace by offering value-added resource solutions to our customers. These solutions range from our customer solutions business, which provides professional services to large industrial institutional or multi-site retail customers, to our organics business, which is a leader in organics processing and disposal in the Northeast, and to our large scale, technology-driven recycling business. Our customer solutions business has continued to improve margins and returns through fiscal year 2019, as we further transformed the business from the legacy brokerage model to a professional services organization focused on providing resource solutions to large industrial and institutional accounts. Over the last three years, we have worked to reshape our recycling business model to drive higher returns in all market cycles and reduce exposure to recycling commodity volatility. We have accomplished this goal by: (1) restructuring most third-party processing contracts to limit downside risk by charging processing fees; (2) implementing our Sustainability Recycling Adjustment Fee (“SRA Fee”) for our collection customers (the SRA Fee floats inversely to changes in recycling commodity prices); (3) making key investments in recycling processing infrastructure to reduce operating costs and improve the quality of the end commodities; and (4) developing strong partnerships with industrial consumers of recycled materials to ensure that the materials our customers recycle make their way into new products and beneficial uses. Our risk mitigation programs have offset most of the recent commodity price declines driven primarily by China’s National Sword program that banned the import of certain recycled materials and imposed strict new contamination standards for others, and we expect these programs to continue to reduce our commodity risk exposure. Using Technology to Drive Profitable Growth and Efficiencies We launched a 5-year technology plan in August 2017 to drive profitable growth, reduce our general and administration costs by 75 to 100 basis points as a percentage of revenues by 2021, and improve our operating efficiencies. We have focused our efforts on improving our overall technology platform, driving sales force effectiveness, and increasing efficiencies in our back- office and across our operations. To date as part of our technology plan, we have successfully implemented: the Microsoft Dynamics CRM system to help manage and drive higher salesforce effectiveness; the Microsoft Dynamics Case Management system to ensure strong integration between our salesforce, customer care group and operating teams; and the cloud-based NetSuite ERP system as the new financial backbone to our business. We plan to focus our technology efforts in the fiscal year ending December 31, 2020 ("fiscal year 2020") on process and technology enhancement for procurement, piloting a new order-to-cash system for our collection line-of-business, and piloting a new on-board computing and dynamic route optimization system. 5 5 Table of Contents Allocating Capital to Balance Debt Delevering with Smart Growth Over the last six years we made significant progress in simplifying our business structure, improving cash flows and reducing risk exposure by: (1) divesting, or in certain cases, closing underperforming operations that did not enhance or complement our core operations; (2) refinancing debt to lower interest costs and improve financial flexibility; and (3) adhering to strict capital discipline and debt repayment. Given our progress in each area and as part of the 2021 Plan, we shifted our capital strategy to use our capital in a manner that balances continued delevering with smart acquisition and development growth. As part of this strategy, we set a goal of adding $20 million to $40 million per year of annualized revenues through acquisition or development activity. We believe that acquisition or development activity should be opportunistic, and we plan to strictly adhere to our disciplined capital return hurdles and rigorous review process. We have made significant progress ramping up our strategic growth initiative, as we have acquired 19 solid waste collection and transfer businesses during fiscal year 2018 and fiscal year 2019, with approximately $130 million of annualized revenues. We expect revenue growth of approximately $30 million in fiscal year 2020 from the full year of revenue from acquisitions completed in 2019, but which contributed to our revenues for only part of the year in 2019. We are focused on acquiring well-run businesses in strategic markets across our footprint that will drive additional internalization to our landfills and operating synergies. We are also focused on more effectively optimizing waste placement around the Northeast as the ever-tightening disposal market is creating additional opportunities to source new volumes at higher prices. Operational Overview Our solid waste and recycling operations comprise a full range of non-hazardous solid waste services, including collections, transfer stations, material recovery facilities ("MRFs") and disposal facilities. Collections. A majority of our commercial and industrial collection services are performed under one-to-five year service agreements, with prices and fees determined by such factors as: collection frequency; type of equipment and containers furnished; type, volume and weight of solid waste collected; distance to the disposal or processing facility; and cost of disposal or processing. Our residential collection and disposal services are performed either on a subscription basis (with no underlying contract) with individuals, or through contracts with municipalities, homeowner associations, apartment building owners or mobile home park operators. Transfer Stations. Our transfer stations receive, compact and transfer solid waste, collected primarily by our various residential and commercial collection operations, for transport to disposal facilities by larger vehicles. We believe that transfer stations benefit us by: (1) increasing the size of the wastesheds which have access to our landfills; (2) reducing costs by improving utilization of collection personnel and equipment; and (3) helping us build relationships with municipalities and other customers by providing a local physical presence and enhanced local service capabilities. Material Recovery Facilities. Our MRFs receive, sort, bale and sell recyclable materials originating from the municipal solid waste stream, including newsprint, cardboard, office paper, glass, plastic, steel or aluminum containers and bottles. We operate six large-scale, high volume MRFs within our Recycling region in geographic areas served by our collection divisions. Revenues are received from municipalities and customers in the form of processing fees, tipping fees and commodity sales. These MRFs, one of which is located in New York, two of which are located in Vermont, two of which are located in Massachusetts, and one of which is located in Maine, process over 0.4 million tons per year of recycled materials delivered to them by municipalities and commercial customers under long-term contracts. We also operate smaller MRFs, which generally process recyclables collected from our various residential and commercial collection operations. Landfills. We operate eight solid waste Subtitle D landfills and one landfill permitted to accept C&D materials. Revenues are received from municipalities and other customers in the form of tipping fees. The estimated capacity at our landfills is subject to change based on engineering factors, requirements of regulatory authorities, our ability to continue to operate our landfills in compliance with applicable regulations and our ability to successfully renew operating permits and obtain expansion permits at our sites. 6 6 7 The following table (in thousands) reflects the aggregate landfill capacity and airspace changes, in tons, for landfills we operated during fiscal years 2019, 2018 and 2017: Fiscal Year 2019Fiscal Year 2018Fiscal Year 2017 EstimatedRemainingPermittedCapacity(1)EstimatedAdditionalPermittableCapacity(1)(2)EstimatedTotalCapacityEstimatedRemainingPermittedCapacity(1)EstimatedAdditionalPermittableCapacity(1)(2)EstimatedTotalCapacityEstimatedRemainingPermittedCapacity(1)EstimatedAdditionalPermittableCapacity(1)(2)EstimatedTotalCapacityBalance, beginning of year35,81047,05382,86336,15946,30182,46031,02259,08990,111New expansions pursued (3)—648648——————Permits granted (4)12,675(12,675)————9,273(9,273)—Airspace consumed(4,048)—(4,048)(4,160)—(4,160)(3,958)—(3,958)Changes in engineering estimates (5)(3)(887)(890)3,8117524,563(178)(3,515)(3,693)Balance, end of year44,43434,13978,57335,81047,05382,86336,15946,30182,460(1)We convert estimated remaining permitted capacity and estimated additional permittable capacity from cubic yards to tons generally by assuming a compaction factor derived from historical average compaction factors, with modification for future anticipated changes. In addition to a total capacity limit, certain permits place a daily and/or annual limit on capacity.(2)Represents capacity which we have determined to be “permittable” in accordance with the following criteria: (i) we control the land on which the expansion is sought; (ii) all technical siting criteria have been met or a variance has been obtained or is reasonably expected to be obtained; (iii) we have not identified any legal or political impediments which we believe will not be resolved in our favor; (iv) we are actively working on obtaining any necessary permits and we expect that all required permits will be received; and (v) senior management has approved the project based on a review of the engineering design and determination that the financial return profile meets our investment criteria.(3)The increase in capacity associated with new expansions pursued in fiscal year 2019 relates to the determination of additional permittable airspace at the NCES Landfill in our Eastern region.(4)The increase in remaining permitted airspace capacity in fiscal year 2019 was the result of a permit received at the Waste USA Landfill and at the Hakes Landfill in our Western region. The increase in remaining permitted capacity in fiscal year 2017 was the result of a permit received at the Juniper Ridge Landfill in our Eastern region. (5)The variation in changes in airspace capacity associated with engineering estimates are primarily the result of changes in compaction at our landfills and estimated airspace changes associated with design changes at certain of our landfills, which in fiscal year 2017 includes the impact associated with the decision to close the Town of Southbridge, Massachusetts landfill ("Southbridge Landfill").Eastern RegionNCES Landfill. NCES Landfill is a Subtitle D landfill located in Bethlehem, New Hampshire that we purchased in 1994. NCES Landfill currently consists of approximately 50 acres of permitted or permittable landfill area, is permitted to accept municipal solid waste, C&D material and certain pre-approved special waste and has no annual tonnage limitations. We have recently been informed by the New Hampshire Division of Environmental Services that it will be necessary to amend our permit application for an additional 1.2 million cubic yards of capacity at the NCES Landfill. This will likely impact the timing of our permit and our results of operations. There can be no assurance that we will receive this permit after it is refiled. In fiscal year 2017, NCES Landfill entered into an agreement for the construction of a landfill gas-to-energy plant, which will be constructed, owned and operated by a third-party once completed.Juniper Ridge Landfill. Juniper Ridge Landfill is a Subtitle D landfill located in West Old Town, Maine. In 2004, we completed transactions with the State of Maine and Georgia-Pacific Corporation (“Georgia Pacific”), pursuant to which the State of Maine took ownership of Juniper Ridge Landfill, formerly owned by Georgia Pacific, and we became the operator under a 30-year operating and services agreement between us and the State of Maine. Juniper Ridge Landfill currently consists of approximately 179 acres of permitted or permittable landfill area, which is sufficient to permit the additional airspace required for the term of the 30-year operating and services agreement, and is permitted to accept the following waste originating from the State of Maine: up to 0.1 million tons of municipal solid waste per year through March 2020, and C&D material, ash from municipal solid waste incinerators and fossil fuel boilers, front end processed residuals and bypass municipal solid waste from waste-to-energy facilities and certain pre-approved special waste. Outside of the limitations on municipal solid waste, there are no annual tonnage limitations at Juniper Ridge Landfill. In fiscal year 2019, Casella entered into an agreement for the construction of a landfill gas-to-energy plant at the Juniper Ridge Landfill, which will be constructed, owned and operated by a third-party.Table of Contents7Table of Contents Western Region Waste USA Landfill. Waste USA Landfill is a Subtitle D landfill located in Coventry, Vermont that we purchased in 1995, and is the only operating permitted Subtitle D landfill in the State of Vermont. Waste USA Landfill consists of approximately 148 acres of permitted or permittable landfill area and is permitted to accept up to 0.6 million tons of municipal solid waste, C&D material and certain pre-approved special waste annually. The Waste USA Landfill site houses a landfill gas-to-energy plant, which is owned and operated by a third-party, that has the capacity to generate 8.0 MW of energy. Clinton County Landfill. Clinton County Landfill is a Subtitle D landfill located in Schuyler Falls, New York. Clinton County Landfill, which currently consists of approximately 197 acres of permitted or permittable landfill area portions of which are leased from Clinton County, is permitted to accept up to approximately 0.25 million tons of municipal solid waste, C&D material and certain pre-approved special waste annually. The Clinton County Landfill site houses a landfill gas-to-energy facility, which is owned by us and operated by a third-party, that has the capacity to generate 6.4 MW of energy. Hyland Landfill. Hyland Landfill is a Subtitle D landfill located in Angelica, New York that we own, and that began accepting waste in 1998. Hyland Landfill currently consists of approximately 121 acres of permitted or permittable landfill area and is permitted to accept up to 0.5 million tons of municipal solid waste, C&D material and certain pre-approved special waste annually. The Hyland Landfill site houses a landfill gas-to-energy facility, which is owned by us and operated by a third-party, that has the capacity to generate 4.8 MW of energy. Ontario County Landfill. Ontario County Landfill is a Subtitle D landfill located in Seneca, New York. In 2003, we entered into a 25-year operation, management and lease agreement for the Ontario County Landfill with the Ontario County Board of Supervisors. Ontario County Landfill currently consists of approximately 171 acres of permitted or permittable landfill area and is permitted to accept up to 0.9 million tons of municipal solid waste, C&D material and certain pre-approved special waste annually and is strategically situated to accept long haul volume from both the eastern and downstate New York markets. In January 2016, we received an expansion permit at the Ontario County Landfill, which is sufficient to permit the additional airspace required for the remaining term of the 25-year operation, management and lease agreement. The Ontario County Landfill site houses a Zero-Sort MRF, which is operated by us, and a landfill gas-to-energy facility, which is owned and operated by a third-party, that has the capacity to generate 11.2 MW of energy. Hakes Landfill. Hakes Landfill is a C&D landfill located in Campbell, New York that we purchased in 1998. Hakes Landfill currently consists of approximately 78 acres of permitted or permittable landfill area and is permitted to accept up to 0.5 million tons of C&D material annually. Chemung County Landfill. Chemung County Landfill is a Subtitle D landfill located in Chemung, New York. In 2005, we entered into a 25-year operation, management and lease agreement for Chemung County Landfill and certain other facilities with Chemung County. Chemung County Landfill currently consists of approximately 113 acres of permitted or permittable landfill area strategically situated to accept long haul volume from both eastern and downstate New York markets and is permitted to accept up to 0.4 million tons of municipal solid waste and certain pre-approved special waste annually and 20.5 thousand tons of C&D material annually. In fiscal year 2016, we received an expansion permit at Chemung County Landfill, which is sufficient to permit the additional airspace required for the remaining term of the 25-year operation, management and lease agreement. In fiscal year 2019, we exercised an option to extend the remaining term of the operation, management and lease agreement for five years through 2035. McKean Landfill. McKean landfill is a Subtitle D landfill located in Mount Jewett, Pennsylvania (“McKean Landfill”) that we purchased in 2011 as part of a bankruptcy reorganization. McKean Landfill currently consists of approximately 256 acres of permitted or permittable landfill area and is permitted to accept up to approximately 0.3 million tons of municipal solid waste, C&D material and certain pre-approved special waste annually. The facility permit authorizes the construction of the rail siding at the landfill which if completed, would expand the market reach for the landfill to other rail capable transfer facilities. We have not yet committed to the construction of the rail siding pending a determination of the economic viability. We believe that McKean Landfill is well situated to provide services to the oil and gas industry that explores natural gas resources in the Marcellus Shale region of Pennsylvania in the form of disposal capacity for residual materials. Closed Landfills In fiscal year 2017, we initiated a plan to cease operations of Southbridge Landfill and decided to not proceed with expansion efforts and to close Southbridge Landfill once the remaining capacity had been exhausted, which occurred in fiscal year 2018. Closure operations, which began in November 2018 when Southbridge Landfill reached its final capacity, are ongoing. In addition to Southbridge Landfill, we own and/or manage five unlined landfills and three lined landfills that are not currently in operation. We are closing, in the case of Southbridge Landfill, or have closed and capped all of these landfills according to applicable environmental regulatory standards. 8 8 9 Operating Segments We have managed operations through four operating segments, including (i) two regional operating segments, which we designate as our Eastern and Western regions, (ii) Recycling, which comprises our larger-scale recycling operations and our commodity brokerage operations and (iii) "Other", which comprises organic services, ancillary operations, along with major accounts and industrial services. Effective January 1, 2020, we reorganized our operating segments as follows: we aligned our organics services and our major account and industrial services, with our Recycling segment to form the Resource Solutions segment, thus creating a single resource renewal-focused segment. We also moved our ancillary transportation services, which were previously included in our Other segment, into our Western region. Accordingly, as of January 1, 2020, our operating segments consist of the Eastern and Western regions and Resource Solutions. See Note 20, Segment Reporting to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for a summary of revenues, certain expenses, profitability, capital expenditures, goodwill, and total assets of our operating segments. Within each geographic region, we organize our solid waste services around smaller areas that we refer to as “wastesheds.” A wasteshed is an area that comprises the complete cycle of activities in the solid waste services process, from collection to transfer operations and recycling to disposal in landfills, some of which may be owned and/or operated by third parties. We typically operate several divisions within each wasteshed, each of which provides a particular service, such as collection, recycling, disposal or transfer. Each division operates interdependently with the other divisions within the wasteshed. Each wasteshed generally operates autonomously from adjoining wastesheds. Through the six MRFs and commodity brokerage operation comprising our Recycling segment, we provide services to five anchor contracts, which have original terms ranging from five to twenty years and expire at various times through calendar year end 2028. The terms of each contract vary, but all of the contracts provide that the municipality or third-party delivers materials to our facility. These contracts may include a minimum volume guarantee by the municipality. We also have service agreements with individual towns and cities and commercial customers, including small solid waste companies and major competitors, that do not have processing capacity within a specific geographic region. The following table provides information about each operating segment (as of January 31, 2020 except revenue information, which is for fiscal year 2019): EasternRegion WesternRegion Recycling Other Revenues (in millions)$219.5$343.4$42.8$137.6Properties:Solid waste collection facilities1726——Transfer stations2434——Recycling facilities3692Subtitle D landfills26——C&D landfills—1——See our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for our financial results for fiscal years 2019, 2018 and 2017, and our financial position as of December 31, 2019 and December 31, 2018. Eastern region Our Eastern region consists of wastesheds located in Maine, northern, central and southeastern New Hampshire and central and eastern Massachusetts. Our Eastern region is vertically integrated, with transfer, landfill, processing and recycling assets serviced by our collection operations.We entered the Maine market in 1996 and have grown organically and through acquisitions. We currently operate the Juniper Ridge Landfill under a 30-year agreement with the State of Maine. We entered the southern New Hampshire market in 1999 and the eastern Massachusetts market in 2000 and since have grown organically and through acquisitions. In this market, we rely to a large extent on third-party disposal capacity, but our landfills and other assets have provided additional opportunities to internalize volumes. In fiscal year 2018, we acquired Complete Disposal Company, Inc. and its subsidiary United Material Management of Holyoke, Inc. (collectively, "Complete"). Complete provides residential and roll-off collection services, and operates a C&D processing facility and a solid waste transfer station with both truck and rail transfer capabilities. In fiscal year 2017, we initiated the plan to cease operations of our Southbridge Landfill and decided to not proceed with expansion efforts and to close the Southbridge Landfill once the remaining capacity had been exhausted, which occurred in fiscal year 2018. Closure operations at the Southbridge Landfill began in November 2018.Table of Contents9Table of Contents Western region Our Western region includes wastesheds located in Vermont, southwestern New Hampshire, eastern, western and upstate New York and in Pennsylvania around McKean Landfill. The portion of eastern New York served by our Western region includes Clinton (operation of Clinton County), Franklin, Essex, Warren, Washington, Saratoga, Rennselaer, and Albany counties. Our Western region also consists of wastesheds in western New York, which includes Ithaca, Elmira, Oneonta, Lowville, Potsdam, Geneva, Auburn, Rochester, Dunkirk, Jamestown and Olean markets. We began entering into these wastesheds in 1997 and have expanded primarily through tuck-in acquisitions and organic growth. Our Western region collection operations include leadership positions in nearly every rural market outside of the larger metropolitan markets such as Syracuse and Buffalo. We remain focused on increasing our vertical integration in our Western region through extension of our reach into new markets and managing new materials. We believe that maximizing these logistics through the use of rail, if implemented, long haul trucks and trailer tippers at our facilities will increase our reach. Recycling Our Recycling segment is one of the largest processors and marketers of recycled materials in the northeastern United States, comprised of six MRFs that process and market recyclable materials that municipalities and commercial customers deliver under long-term contracts. Two of the six MRFs are leased, three are owned, and one is operated by us under a contract with municipal third-party. In fiscal year 2019, our Recycling segment processed and/or marketed over 0.7 million tons of recyclable materials including tons marketed through our commodity brokerage division and our baling facilities located throughout our footprint. Recycling’s facilities are located in Vermont, New York, Maine, and Massachusetts. A substantial portion of the material provided to Recycling is delivered pursuant to five anchor contracts. The anchor contracts have an original term of five to twenty years and expire at various times through 2028. The terms of the recycling contracts vary, but all of the contracts provide that the municipality or a third-party delivers the recycled materials to our facility. Under the recycling contracts, we charge the municipality a fee for each ton of material delivered to us. Some contracts contain revenue sharing arrangements under which the municipality receives a specified percentage of our revenues from the sale of the recovered materials if certain economic thresholds are met. Our Recycling segment has historically derived a significant portion of its revenues from the sale of recyclable materials, particularly newspaper, corrugated containers, plastics, ferrous and aluminum. The pricing for these materials can fluctuate based upon market conditions. However, we have actively worked to reduce our risk exposure to commodity pricing volatility over the last four years through our efforts to shift customers to a processing fee model and other risk management programs. In fiscal year 2019, we generated 36.8% of Recycling segment revenues from commodity sales as compared to 77.6% in the fiscal year ended December 31, 2015. We effectively manage commodity pricing volatility through our long-term revenue sharing (or processing fee) contracts with customers. Under such contracts, we obtain a guaranteed minimum price for recyclable materials through the receipt of a tipping or processing fee when commodity prices fall below agreed upon thresholds. Conversely, when prices for recyclable materials rise above agreed upon thresholds, we provide the counterparty with a portion of the related revenues above such threshold. Also, we mitigate the impact from commodity price fluctuations through the use of a floating SRA fee charged to collection customers to offtake recycling commodity risk. Further, we work to manage commodity pricing risk through commodity sales contracts with large domestic companies that use the recyclable materials in their manufacturing process, such as paper, packaging and consumer goods companies. At times, we also hedge against fluctuations in the commodity prices of recycled paper and corrugated containers in order to mitigate the variability in cash flows and earnings generated from the sales of recycled materials at floating prices. As of December 31, 2019, no such commodity hedges were in place. The global recycling market has experienced negative commodity pricing pressure resulting from China's National Sword program in 2017. Markets continued to decline in 2019, leveling off at historical lows compared to prior years. We expect markets to remain depressed into the foreseeable future. Other Our Other segment derives a significant portion of its revenues from our Customer Solutions and Organics businesses. Our resource solutions strategy seeks to leverage our core competencies in materials processing, industrial recycling, clean energy, and organics service offerings in order to generate additional value from the waste stream for our customers. Our Customer Solutions business works with larger scale organizations (including multi-location customers, colleges and universities, municipalities, and industrial customers) to develop customized solid waste solutions. The focus of this business is to help these large-scale organizations achieve their economic and environmental objectives related to waste and residual management. We differentiate our services from our competitors by providing customized and comprehensive resource solutions, which enables us to win new business, including traditional solid waste collection and disposal customers. 10 10 11 Our Organics business has been working to develop and/or partner with firms that have developed innovative approaches to deriving incremental value from the organic portion of the waste stream. Through our earthlife® soils products, we offer a wide array of organic fertilizers, composts, and mulches that help our customers recycle organic waste streams. We also have ownership interests in AGreen Energy, LLC and BGreen Energy, LLC, which we account for as cost method investments, that partner with other capital investors to build farm-based anaerobic digesters in the northeastern United States to generate electricity from farm and food waste streams. CompetitionThe solid waste services industry is highly competitive. We compete for collection and disposal volume primarily on the basis of the quality, breadth and price of our services. From time to time, competitors may reduce the price of their services in an effort to expand market share or to win a competitively bid municipal contract. These practices may also lead to reduced pricing for our services or the loss of business. In addition, competition exists within the industry for potential acquisition candidates.Our business strategy generally focuses on operating in secondary or tertiary markets where we have a leading market share. However, in the larger urban markets where we operate, we typically compete against one or more of the large national solid waste companies, including Waste Management, Inc., Republic Services, Inc. and Waste Connections, Inc., any of which may be able to achieve greater economies of scale than we can. We also compete with a number of regional and local companies that offer competitive prices and quality service. In addition, we compete with operators of alternative disposal facilities, including incinerators; with certain municipalities, counties and districts that operate their own solid waste collection and disposal facilities; and with rail-serviced transfer stations that use rail transport to move waste to disposal sites outside of northeastern markets. Public sector facilities may have certain advantages over us due to the availability of user fees, charges or tax revenues.Marketing and SalesWe have fully integrated sales and marketing strategies with a primary focus on acquiring and retaining commercial, industrial, municipal and residential customers. Our business strategy focuses on creating a highly differentiated sustainable resource management model that meets customers’ unique needs and provides value “beyond the curb”.Maintenance of a local presence and identity is an important aspect of our sales and marketing strategy, and many of our divisional managers are involved in local governmental, civic and business organizations. Our name and logo, or, where appropriate, that of our divisional operations, are displayed on all of our containers and trucks. We attend and make presentations at municipal and state meetings, and we advertise in a variety of media throughout our service footprint.The Customer Solutions business serves customers with multiple locations and is focused on growing our share of business with municipal, institutional, commercial and industrial customers. This group provides customers with a broader set of solutions to augment our regional and divisional service capabilities.Marketing activities are focused on retaining existing customers and attracting new commercial and residential customers directly on-route in order to enhance profitability. Marketing campaigns are integrated with divisional management teams, sales personnel and the centralized customer care center.EmployeesAs of January 31, 2020, we employed approximately 2,500 employees, including approximately 500 professionals or managers, sales, clerical, information systems or other administrative employees and approximately 2,000 employees involved in collection, transfer, disposal, recycling or other operations. Approximately 150 of our employees are covered by collective bargaining agreements. We believe relations with our employees are strong.Risk Management, Insurance and Performance or Surety BondsWe actively maintain environmental and other risk management programs that we believe are appropriate for our business. Our environmental risk management program includes evaluating existing facilities, as well as potential acquisitions, for compliance with environmental law requirements. Operating practices at all of our operations are intended to reduce the possibility of environmental contamination, enforcement actions and litigation. We also maintain a worker safety program, which focuses on safe practices in the workplace.Table of Contents11Table of Contents We carry a range of insurance intended to protect our assets and operations, including a commercial general liability policy and a property damage policy. A partially or completely uninsured claim against us (including liabilities associated with cleanup or remediation at our facilities), if successful and of sufficient magnitude, could have a material adverse effect on our business, financial condition and results of operations. Due primarily to market factors beyond our control, the insurance market is increasingly restrictive, prohibiting our ability to obtain adequate coverage at reasonable prices, if at all. Any future difficulty in obtaining insurance could also impair our ability to secure future contracts, which may be conditioned upon the availability of adequate insurance coverage. See the risk factor titled “Our insurance coverage and self-insurance reserves may be inadequate to cover all significant risk exposures” in Item 1A, “Risk Factors” of this Annual Report on Form 10-K. See also Item 3, “Legal Proceedings” and Note 12, Commitments and Contingencies to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K. We self-insure for automobile and workers’ compensation coverage with reinsurance coverage limiting our maximum exposure. Our maximum exposure in fiscal year 2019 under the workers’ compensation plan was $1.25 million per individual event. Our maximum exposure in fiscal year 2019 under the automobile plan was $1.2 million per individual event. Effective, January 1, 2020, our maximum exposure under the automobile plan was increased to $1.65 million per individual event. Municipal solid waste collection contracts and landfill closure and post-closure obligations may require performance or surety bonds, letters of credit or other means of financial assurance to secure contractual performance. While we have not experienced difficulty in obtaining these financial instruments, if we are unable to obtain these financial instruments in sufficient amounts or at acceptable rates we could be precluded from entering into additional municipal contracts or obtaining or retaining landfill operating permits. We hold a 19.9% ownership interest in Evergreen National Indemnity Company (“Evergreen”), a surety company which provides surety bonds to secure our contractual obligations for certain municipal solid waste collection contracts and landfill closure and post-closure obligations. Our ownership interest in Evergreen is pledged to Evergreen as security for our obligations under the bonds they provide on our behalf. Customers We provide our collection services to commercial, institutional, industrial and residential customers. A majority of our commercial and industrial collection services are performed under one-to-five year service agreements, and fees are determined by such factors as: professional or management services required; collection frequency; type of equipment and containers furnished; the type, volume and weight of the solid waste, recyclables or organics collected; the distance to the disposal or processing facility; and the cost of disposal or processing. Our residential collection and disposal services are performed either on a subscription basis (with no underlying contract) with individuals, or through contracts with municipalities, homeowners' associations, apartment owners or mobile home park operators. Our Recycling segment provides recycling services to municipalities, commercial haulers and commercial waste generators within the geographic proximity of the processing facilities. 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: • • 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. 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 Recycling segment experiences increased volumes of fiber in November and December due to increased retail activity during the holiday season. 12 12 13 RegulationIntroductionWe are subject to extensive federal, state and local environmental laws and regulations. The environmental regulations affecting us are administered by the United States Environmental Protection Agency (“EPA”) and other federal, state and local environmental, zoning, health and safety agencies. Failure to comply with such requirements could result in substantial costs, including civil and criminal fines and penalties. Except as described in this Annual Report on Form 10-K, we believe that we are currently in substantial compliance with applicable federal, state and local environmental laws, permits, orders and regulations. Other than as disclosed herein, we do not currently anticipate any material costs to bring our existing operations into environmental compliance, although there can be no assurance in this regard for the future. We expect that our operations in the solid waste services industry will be subject to continued and increased regulation, legislation and enforcement oversight. We attempt to anticipate future legal and regulatory requirements and to keep our operations in compliance with those requirements.In order to transport, process, or dispose of solid waste, it is necessary for us to possess and comply with one or more permits from federal, state and/or local agencies. We must renew these permits periodically, and the permits may be modified or revoked by the issuing agency under certain circumstances.The principal federal statutes and regulations applicable to our operations are as follows:The Resource Conservation and Recovery Act of 1976, as amended (“RCRA”)The RCRA regulates the generation, treatment, storage, handling, transportation and disposal of solid waste and requires states to develop programs to ensure the safe disposal of solid waste. The RCRA divides waste into two categories, hazardous and non-hazardous. Wastes are generally classified as hazardous if they either (a) are specifically included on a list of hazardous wastes, or (b) exhibit certain characteristics defined as hazardous and are not specifically designated as non-hazardous. Wastes classified as hazardous waste are subject to more extensive regulation than wastes classified as non-hazardous, and businesses that deal with hazardous waste are subject to regulatory obligations in addition to those imposed on businesses that deal with non-hazardous waste.Among the wastes that are specifically designated as non-hazardous are household waste and “special” waste, including items such as petroleum contaminated soils, asbestos, foundry sand, shredder fluff and most non-hazardous industrial waste products.The EPA regulations issued under Subtitle C of the RCRA impose a comprehensive “cradle to grave” system for tracking the generation, transportation, treatment, storage and disposal of hazardous wastes. Subtitle C regulations impose obligations on generators, transporters and disposers of hazardous wastes, and require permits that are costly to obtain and maintain for sites where those businesses treat, store or dispose of such material. Subtitle C requirements include detailed operating, inspection, training and emergency preparedness and response standards, as well as requirements for manifesting, record keeping and reporting, corrective action, facility closure, post-closure and financial responsibility. Most states have promulgated regulations modeled on some or all of the Subtitle C provisions issued by the EPA, and in many instances the EPA has delegated to those states the principal role in regulating businesses which are subject to those requirements. Some state regulations impose obligations different from and in addition to those the EPA imposes under Subtitle C.Leachate generated at our landfills and transfer stations is tested on a regular basis, and generally is not regulated as a hazardous waste under federal law. However, there is no guarantee that leachate generated from our facilities in the future will not be classified as hazardous waste.In October 1991, the EPA adopted the Subtitle D regulations under RCRA governing solid waste landfills. The Subtitle D regulations, which generally became effective in October 1993, include siting restrictions, facility design standards, operating criteria, closure and post-closure requirements, financial assurance requirements, groundwater monitoring requirements, groundwater remediation standards and corrective action requirements. In addition, the Subtitle D regulations require that new landfill sites meet more stringent liner design criteria (typically, composite soil and synthetic liners or two or more synthetic liners) intended to keep leachate out of groundwater and have extensive collection systems to carry away leachate for treatment prior to disposal. Regulations generally require us to install groundwater monitoring wells at virtually all landfills we operate, to monitor groundwater quality and, indirectly, the effectiveness of the leachate collection systems. The Subtitle D regulations also require facility owners or operators to control emissions of landfill gas (including methane) generated at landfills exceeding certain regulatory thresholds. State landfill regulations must meet those requirements or the EPA will impose such requirements upon landfill owners and operators in that state.Table of Contents13Table of Contents The Federal Water Pollution Control Act of 1972, as amended (“Clean Water Act”) The Clean Water Act regulates the discharge of pollutants into the “waters of the United States” from a variety of sources, including solid waste disposal sites and transfer stations, processing facilities and waste-to-energy facilities (collectively, “solid waste management facilities”). If run-off or treated leachate from our solid waste management facilities is discharged into streams, rivers or other surface waters, the Clean Water Act would require us to apply for and obtain a discharge permit, conduct sampling and monitoring and, under certain circumstances, reduce the quantity of pollutants in such discharge. A permit also may be required if that run-off or leachate is discharged to an offsite treatment facility. The U.S. Supreme Court is currently considering whether discharges to groundwater also require permits under the Clean Water Act. County of Maui, Hawaii v. Hawaii Wildlife Fund, Docket No. 18-260. Almost all solid waste management facilities must comply with the EPA’s storm water regulations, which govern the discharge of regulated storm water to surface waters. Under federal regulation, facilities that have above ground and/or below ground petroleum storage capacities over certain thresholds may be subject to regulations and/or permitting under the Clean Water Act. Many of our facilities have petroleum storage and are required to have a spill, prevention, control and countermeasures (“SPCC”) plan to prevent petroleum release to waters of the U.S. due to a spill, rupture or leak. Several states in which we operate have been delegated the authority to implement the Clean Water Act requirements and in some cases the regulations are more stringent than the federal regulations. We believe we are in compliance with the Clean Water Act regulations; however future changes to the law or regulations could have a material impact on our business. The Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (“CERCLA”) CERCLA established a regulatory and remedial program intended to provide for the investigation and remediation of facilities where, or from which, a release of any hazardous substance into the environment has occurred or is threatened. CERCLA has been interpreted to impose retroactive, strict, and under certain circumstances, joint and severable, liability for the costs to investigate and clean up facilities on current owners and operators of the site, former owners and operators of the site at the time of the disposal of the hazardous substances, as well as the generators and certain transporters of the hazardous substances. CERCLA imposes liability for the costs of evaluating and addressing damage to natural resources. The costs of CERCLA investigation and cleanup can be substantial. Liability under CERCLA does not depend upon the existence or disposal of “hazardous waste” as defined by RCRA, but can be based on the presence of any of more than 700 “hazardous substances” listed by the EPA, many of which can be found in household waste. The definition of “hazardous substances” in CERCLA incorporates substances designated as hazardous or toxic under the Federal Clean Water Act, Clean Air Act and Toxic Substances Control Act ("TSCA"). If we were found to be a responsible party for a CERCLA cleanup, under certain circumstances, the enforcing agency could pursue us or any other responsible party, for all investigative and remedial costs, even if others also were liable. CERCLA also authorizes the EPA to impose a lien in favor of the United States upon all real property subject to, or affected by, a remedial action for all costs for which the property owner is liable. CERCLA provides a responsible party with the right to bring a contribution action against other responsible parties for their allocable share of investigative and remedial costs. Our ability to obtain reimbursement for amounts we pay in excess of our allocable share of such costs would be limited by our ability to identify and locate other responsible parties and to prove the extent of their responsibility and by the financial resources of such other parties. The Clean Air Act of 1970, as amended (“Clean Air Act”) The Clean Air Act, generally through state implementation of federal requirements, regulates emissions of air pollutants from certain landfills based upon the date the landfill was constructed, the total capacity of the landfill and the annual volume of emissions. The EPA has promulgated new source performance standards regulating air emissions of certain regulated pollutants (non-methane organic compounds) from municipal solid waste landfills. Landfills located in areas where ambient levels of regulated pollutants exceed certain thresholds may be subject to more extensive air pollution controls and emission limitations. In addition, the EPA has issued standards regulating the disposal of asbestos-containing materials under the Clean Air Act. The EPA is also focusing on the emissions of greenhouse gases, or GHG, including carbon dioxide and methane. In December 2009, the EPA issued its “endangerment finding” that carbon dioxide poses a threat to human health and welfare, providing the basis for the EPA to regulate GHG emissions. In December 2009 the EPA’s “Mandatory Reporting of Greenhouse Gases” rule went into effect, requiring facilities that emit twenty-five thousand metric tons or more per year of GHG emissions to submit annual reports to the EPA. In 2010, the EPA issued the so-called “GHG Tailoring Rule”, which described how certain sources that emit GHG would be subject to heightened Clean Air Act Prevention of Significant Deterioration ("PSD") / Title V regulation. In June 2014, the U.S. Supreme Court issued a decision partially invalidating the GHG Tailoring Rule and in 2015, the D.C. Circuit directed the EPA to consider further revisions to its regulations. We do not know whether or when the EPA will finalize regulations following the Supreme Court and D.C. Circuit decisions, or what obligations such regulations will impose on our operations. 14 14 15 The adoption of other laws and regulations, which may include the imposition of fees or taxes, could adversely affect our collection and disposal operations. Additionally, certain of the states in which we operate are implementing air pollution control regulations, including regional cap and trade systems, relating to GHG that may be more stringent than regulations the EPA may promulgate. Changing environmental regulations could require us to take any number of actions, including purchasing emission allowances or installing additional pollution control technology, and could make some operations less profitable, which could adversely affect our results of operations.Congress has considered various options, including a cap and trade system, which could impose a limit on and establish a pricing mechanism for GHG emissions and emission allowances. There also is pressure for the United States to join international efforts to control GHG emissions.The Clean Air Act regulates emissions of air pollutants from our processing facilities. The EPA has enacted standards that apply to those emissions. It is possible that the EPA, or a state where we operate, will enact additional or different emission standards in the future.All of the federal statutes described above authorize lawsuits by private citizens to enforce certain provisions of the statutes. In addition to a penalty award to the United States, some of those statutes authorize an award of attorney’s fees to private parties successfully advancing such an action.The Occupational Safety and Health Act of 1970, as amended (“OSHA”)OSHA establishes employer responsibilities and authorizes the Occupational Safety and Health Administration to promulgate and enforce occupational health and safety standards, including the obligation to maintain a workplace free of recognized hazards likely to cause death or serious injury, to comply with adopted worker protection standards, to maintain certain records, to provide workers with required disclosures and to implement certain health and safety training programs. A variety of those promulgated standards may apply to our operations, including those standards concerning notices of hazards, safety in excavation and demolition work, the handling of asbestos and asbestos-containing materials, and worker training and emergency response programs.The Public Utility Regulatory Policies Act of 1978, As Amended (“PURPA”)PURPA exempts qualifying facilities from most federal and state laws governing the financial organization and rate regulation of electric utilities, and generally requires electric utilities to purchase electricity generated by qualifying facilities at a price equal to the utility’s full “avoided cost”. Our five landfill gas-to-energy facilities are self- certified as “qualifying facilities”.State and Local RegulationsEach state in which we now operate or may operate in the future has laws and regulations governing (1) water and air pollution, and the generation, storage, treatment, handling, processing, transportation, incineration and disposal of solid waste and hazardous waste; (2) in most cases, the siting, design, operation, maintenance, closure and post-closure maintenance of solid waste management facilities; and (3) in some cases, vehicle emissions limits or fuel types, which impact our collection operations. Such standards typically are as stringent as, and may be more stringent and broader in scope than, federal regulations. Most of the federal statutes noted above authorize states to enact and enforce laws with standards that are more protective of the environment than the federal analog. In addition, many states have adopted statutes comparable to, and in some cases more stringent than, CERCLA. Those statutes impose requirements for investigation and remediation of contaminated sites and liability for costs and damages associated with such sites, and some authorize the state to impose liens to secure costs expended addressing contamination on property owned by responsible parties. Some of those liens may take priority over previously filed instruments. Some states have enacted statutes that impose liability for substances in addition to the “hazardous substances” listed by EPA under CERCLA.Many municipalities in which we currently operate or may operate in the future also have ordinances, laws and regulations affecting our operations. These include zoning and health measures that limit solid waste management activities to specified sites or conduct, flow control provisions that direct the delivery of solid wastes to specific facilities or to facilities in specific areas, laws that grant the right to establish franchises for collection services and then put out for bid the right to provide collection services, and bans or other restrictions on the movement of solid wastes into a municipality.Some states have enacted laws that allow agencies with jurisdiction over waste management facilities to deny or revoke permits based on the applicant’s or permit holder’s compliance status. Some states also consider the compliance history of the corporate parent, subsidiaries and affiliates of the applicant or permit holder.Table of Contents15Table of Contents Certain permits and approvals issued under state or local law may limit the types of waste that may be accepted at a solid waste management facility or the quantity of waste that may be accepted at a solid waste management facility during a specific time period. In addition, certain permits and approvals, as well as certain state and local regulations, may limit a solid waste management facility to accepting waste that originates from specified geographic areas or seek to restrict the importation of out- of-state waste or otherwise discriminate against out-of-state waste. Generally, restrictions on importing out-of-state waste have not withstood judicial challenge. However, from time to time federal legislation is proposed which would allow individual states to prohibit the disposal of out-of-state waste or to limit the amount of out-of-state waste that could be imported for disposal and would require states, under certain circumstances, to reduce the amounts of waste exported to other states. Although such legislation has not been passed by Congress, if similar legislation is enacted, states in which we operate solid waste management facilities could limit or prohibit the importation of out-of-state waste. Such actions could materially and adversely affect the business, financial condition and results of operations of any of our landfills within those states that receive a significant portion of waste originating from out-of-state. Certain states and localities may restrict the export of waste from their jurisdiction, or require that a specified amount of waste be disposed of at facilities within their jurisdiction. In 1994, the U.S. Supreme Court rejected as unconstitutional and therefore invalid, a local ordinance that sought to limit waste going out of the locality by imposing a requirement that the waste be delivered to a particular privately-owned facility. However, in 2007, the U.S. Supreme Court upheld a U.S. District Court ruling that the flow control regulations in Oneida and Herkimer counties in New York requiring trash haulers to use publicly-owned transfer stations are constitutional, and therefore valid. Additionally, certain state and local jurisdictions continue to seek to enforce such restrictions. Some proposed federal legislation would allow states and localities to impose flow restrictions. Those restrictions could reduce the volume of waste going to solid waste management facilities in certain areas, which may materially adversely affect our ability to operate our facilities and/or affect the prices we can charge for certain services. Those restrictions also may result in higher disposal costs for our collection operations. Flow control restrictions could have a material adverse effect on our business, financial condition and results of operations. There has been an increasing trend at the state and local levels to mandate or encourage both waste reduction at the source and waste recycling, and to prohibit or restrict the disposal in landfills of certain types of solid wastes, including yard wastes and leaves, certain construction or architectural wastes, food wastes, beverage containers, newspapers, household appliances and electronics such as computers, and batteries. Regulations reducing the volume and types of wastes available for transport to and disposal in landfills could affect our ability to operate our landfill facilities. Vermont, for example, enacted Act 148, containing among other things, a phased waste ban for recyclables, organics and leaf/yard waste. The law became effective July 1, 2012, with phased deadlines for compliance beginning 2014 through 2020. Vermont also passed a law requiring recycling of architectural waste from construction or demolition of a commercial project. The law became effective in January 2015. Massachusetts revised its regulations governing solid waste management with a framework to encourage the re-use of organic waste material and prohibiting such material from disposal for large-scale commercial generators by October 2014. New York State revised its regulations governing solid waste management, 6 NYCRR Part 360, effective in November 2017. The revised regulations, among other things, include requirements to conduct landfill liner integrity testing and install radiation detectors at certain facilities. Although there is no federal law governing extended producer responsibility (“EPR”) regulations; many states have implemented or are contemplating EPR regulations for certain products. EPR regulations are intended to place responsibility for ultimate management or end-of-useful-life handling of the products they create. In addition to financial responsibility, an EPR program may include responsibility for local take-back or recycling programs. For example, several states in which we operate have EPR regulations for electronic waste. If broad EPR laws or regulations were adopted and managed under a manufacturer implemented program, it could have an impact on our business. The EPA and environmental agencies within individual states in which we operate also consider and promulgate changes to water quality standards, action levels, remediation goals, and other federal or state regulatory standards for individual compounds or classes of compounds. These changes can also include the development of new or more stringent standards for “Emerging Contaminants”, including per- and polyfluoroalkyl substances ("PFASs"), pharmaceutical compounds, and a variety of synthetic chemical compounds used in manufacturing and industrial processes. In December 2016, EPA also designated ten chemical substances for risk evaluations under TSCA, and in December 2019, EPA designated an additional 20 chemical substances for risk evaluation, based on the requirements of the June 2016 Frank R. Lautenberg Chemical Safety for the 21st Century Act. Changes in regulatory standards for existing or emerging contaminants can result in higher levels of cost and effort associated with the performance of environmental investigations and ongoing compliance at our facilities. 16 16 17 Information about our Executive OfficersOur executive officers and their respective ages are as follows:NameAgePositionJohn W.

RISK FACTORS The following important factors, among others, could cause actual results to differ materially from those indicated by forward- looking statements made in this Annual Report on Form 10-K and presented elsewhere by management from time to time. The risks and uncertainties described below are those that we have identified as material, but are not the only risks and uncertainties facing us. Our business is also subject to general risks and uncertainties that affect many other companies, including overall economic and industry conditions, especially in the northeastern United States, where our operations and customers are principally located, changes in laws or accounting rules or other disruptions of expected economic or business conditions. Additional risks and uncertainties not currently known to us or that we currently believe are not material also may impair our business’s results of operations and financial condition. We have in place an Enterprise Risk Management process that involves systematic risk identification and mitigation covering the categories of strategic, financial, operational, and compliance risk. The goal of enterprise risk management is not to eliminate all risk, but rather to identify and assess risks; assign, mitigate and monitor risks; and report the status of our risks to the Board of Directors and its committees. Risks Related to Our Business We face substantial competition in the solid waste services industry, and if we cannot successfully compete in the marketplace, our business, financial condition and results of operations may be materially adversely affected. The solid waste services industry is highly competitive, has undergone a period of consolidation and requires substantial labor and capital resources. The markets in which we compete are served by, or are adjacent to markets served by, one or more of the large national or super regional solid waste companies, as well as numerous regional and local solid waste companies. Intense competition exists not only to provide services to customers, but also to acquire other businesses within each market. Some of our competitors have significantly greater financial and other resources than we do. From time to time, competitors may reduce the price of their services in an effort to expand market share or to win a competitively bid contract. These practices may require us to reduce the pricing of our services and may result in a loss of business. As is generally the case in our industry, municipal contracts are typically subject to periodic competitive bidding. We may not be the successful bidder to obtain or retain these contracts. If we are unable to compete with larger and better capitalized companies or replace municipal contracts lost through the competitive bidding process with comparable contracts or other revenue sources within a reasonable time period, our revenues would decrease and our operating results could be materially adversely affected. In our solid waste disposal markets, we also compete with operators of alternative disposal and recycling facilities and with counties, municipalities and solid waste districts that maintain their own solid waste collection, recycling and disposal operations. We are also increasingly competing with companies which seek to use parts of the waste stream as feedstock for renewable energy supplies. Public entities may have financial advantages because of their ability to charge user fees or similar charges, impose taxes and apply resulting revenues, access tax-exempt financing, transport waste to disposal sites outside of the northeastern markets, and, in some cases, utilize government subsidies. In addition, we may be impacted by the development and commercialization of disruptive technologies that may materially change how waste management services are provided. If we are unable to gain access to these technologies or to compete effectively against them, our financial results may suffer. We also experience competition in our hiring of drivers and mechanics necessary to service our customers. This competition may come from other waste management companies, but it also comes from other employers who hire drivers and maintain fleets, such as companies that provide courier delivery services, including United Parcel Service, Inc. and FedEx Corporation, as well as from a tightening labor market. If we are unable to hire and retain sufficient numbers of drivers to service our collection and disposal routes and mechanics to maintain our trucks, our financial condition and operating results could be materially impacted. 18 18 19 Our growth strategy focuses on complementing or expanding our business through the acquisition of companies or assets, or the development of new operations. However, we may be unable to complete these transactions and, if executed, these transactions may not improve our business or may pose significant risks and could have a negative effect on our operations.Our growth strategy includes engaging in acquisitions or developing operations or assets with the goal of complementing or expanding our business. These acquisitions may include “tuck-in” acquisitions within our existing markets, acquisitions of assets that are adjacent to or outside of our existing markets, or larger, more strategic acquisitions. In addition, from time to time we may acquire businesses that are complementary to our core business strategy. We may not be able to identify suitable acquisition candidates, and if we identify suitable acquisition candidates, we may be unable to successfully negotiate the acquisition at a price or on terms and conditions acceptable to us. Furthermore, we may be unable to obtain the necessary regulatory approvals to complete potential acquisitions.Our ability to achieve the benefits from any potential future acquisitions, including cost savings and operating efficiencies, depends in part on our ability to successfully integrate the operations of such acquired businesses with our operations. The integration of acquired businesses and other assets may require significant management time and resources that would otherwise be available for the ongoing management of our existing operations. Any operations, properties or facilities that we acquire may be subject to unknown liabilities, such as undisclosed environmental contamination, or other environmental liability, including off-site disposal liability for which we would have no recourse, or only limited recourse, to the former owners of such operations or properties. As a result, if a liability were asserted against us based upon ownership of an acquired property, we might be required to pay significant sums to settle it, which could adversely affect our financial results and cash flow.The waste management industry is undergoing fundamental change as traditional waste streams are increasingly viewed as renewable resources, which may adversely affect volumes and tipping fees at our landfills. As we continue to develop our landfill capacity, the waste management industry is recognizing the value of the waste stream as a renewable resource, and accordingly, alternatives to landfilling are being developed that seek to maximize the renewable energy and other resource benefits of solid waste. These alternatives affect the demand for landfill airspace, and could affect our ability to operate our landfills at full capacity, as well as the tipping fees and prices that waste management companies generally, and that we, in particular, can charge for landfill airspace. Reduced tipping fees can affect our willingness to incur the expenditures necessary to increase the permitted capacity of the landfills. As a result, our revenues and operating margins could be materially adversely affected due to these disposal alternatives. The waste industry is subject to extensive government regulations, including environmental laws and regulations, and we incur substantial costs to comply with such laws and regulations. Failure to comply with environmental or other laws and regulations, as well as enforcement actions and litigation arising from an actual or perceived breach of such laws and regulations, could subject us to fines, penalties, and judgments, and impose limits on our ability to operate and expand.We are subject to potential liability and restrictions under environmental laws and regulations, including potential liability and restrictions arising from or relating to the transportation, handling, recycling, generation, treatment, storage and disposal of wastes, the presence, release, discharge or emission of pollutants, and the investigation, remediation and monitoring of impacts to soil, surface water, groundwater and other environmental media including natural resources, as a result of the actual or alleged presence, release, discharge or emission of hazardous substances, pollutants or contaminants on, at, under or migrating from our properties, or in connection with our operations. The waste management industry has been and will continue to be subject to regulation, including permitting and related financial assurance requirements, as well as attempts to further regulate the industry, including efforts to regulate and limit the emission of greenhouse gases. Our solid waste operations are subject to a wide range of federal, state and, in some cases, local environmental, odor and noise and land use restrictions. If we are not able to comply with the requirements that apply to a particular facility or if we operate in violation of the terms and conditions of, or without the necessary approvals or permits, we could be subject to administrative or civil, and possibly criminal, fines and penalties, and we may be required to spend substantial capital to bring an operation into compliance, to temporarily or permanently discontinue activities, and/or take corrective actions, possibly including removal of landfilled materials. Those costs or actions could be significant to us and affect our results of operations, cash flows, and available capital. Environmental and land use laws and regulations also affect our ability to expand and, in the case of our solid waste operations, may dictate those geographic areas from which we must, or, from which we may not, accept solid waste. Those laws and regulations may limit the overall size and daily solid waste volume that may be accepted by a solid waste operation. If we are not able to expand or otherwise operate one or more of our facilities because of limits imposed under such laws, we may be required to increase our utilization of disposal facilities owned by third-parties, which could reduce our revenues and/or operating margins.Table of Contents19Table of Contents In addition to complying with environmental laws and regulations, we are required to obtain government permits to operate our facilities, including all of our landfills. There is no guarantee that we will be able to obtain the requisite permits and, even if we could, that any permit (and any existing permits we currently hold) will be renewed or modified as needed to fit our business needs. We have recently been informed by the New Hampshire Division of Environmental Services that it will be necessary to amend our permit application for an additional 1.2 million cubic yards of capacity at the NCES Landfill. This will likely impact the timing of our permit and our results of operations. There can be no assurance that we will receive this permit after it is refiled and if it is determined that the likelihood of receiving the expansion permit become remote, the capitalized costs related to the expansion effort will be expensed immediately. Localities where we operate generally seek to regulate some or all landfill and transfer station operations, including siting and expansion of operations. The laws and regulations adopted by municipalities in which our landfills and transfer stations are located may limit or prohibit the expansion of a landfill or transfer station, as well as the amount of solid waste that we can accept at the landfill or transfer station on a daily, quarterly or annual basis, and any effort to acquire or expand landfills and transfer stations, which typically involves a significant amount of time and expense. In addition, state laws applicable to certain of our landfills require that the state determine whether acceptance of waste at the landfill not generated within the state provides a substantial public benefit. We may not be successful in obtaining new landfill or transfer station sites or expanding the permitted capacity of any of our current landfills and transfer stations. If we are unable to develop additional disposal and transfer station capacity, our ability to achieve economies from the internalization of our waste stream will be limited. If we fail to receive new landfill permits or renew existing permits, we may incur landfill asset impairment and other charges associated with accelerated closure. We have historically grown through acquisitions, may make additional acquisitions in the future, and we have tried and will continue to try to evaluate and limit environmental risks and liabilities presented by businesses to be acquired prior to the acquisition. It is possible that some liabilities may prove to be more difficult or costly to address than we anticipate. It is also possible that government officials responsible for enforcing environmental laws and regulations may believe an issue is more serious than we expect, or that we will fail to identify or fully appreciate an existing liability before we become responsible for addressing it. Some of the legal sanctions to which we could become subject could cause the suspension or revocation of a permit, prevent us from, or delay us in, obtaining or renewing permits to operate or expand our facilities, or harm our reputation. As of December 31, 2019, we have recorded a $1.2 million environmental remediation liability for the estimated cost of our share of work associated with a consent order issued by the State of New York to remediate a scrap yard and solid waste transfer station owned by one of our acquired subsidiaries, including the recognition of accretion expense, and a $4.6 million environmental remediation liability related to our obligation associated with installation of a municipal waterline associated with Southbridge Recycling & Disposal Park, Inc. discussed in Item 3, "Legal Proceedings" of this Annual Report on Form 10-K, including the recognition of accretion expense in other accrued liabilities and other long-term liabilities. There can be no assurance that the cost of such cleanup or that our share of that cost will not exceed our estimates. In addition to the costs of complying with environmental laws and regulations, we incur costs in connection with environmental proceedings and litigation brought against us by government agencies and private parties. We are, and may be in the future, a defendant in lawsuits brought by parties alleging environmental damage, including natural resource damage, personal injury, and/or property damage or impairment, or seeking to impose civil penalties, injunctive relief or overturn or prevent the issuance of an operating permit or authorization, all of which may result in us incurring significant liabilities. For information about the material outstanding claims against us and our subsidiaries, see Item 3. “Legal Proceedings” in this Annual Report on Form 10- K. We may not have sufficient insurance coverage for our environmental liabilities, such coverage may not cover all of the potential liabilities we may be subject to and/or we may not be able to obtain insurance coverage in the future at reasonable expense, or at all. The conduct of our businesses is also subject to various other laws and regulations administered by federal, state and local governmental agencies, including tax laws, employment laws and competition laws, among others. New laws, regulations or governmental policy and their related interpretations, or changes in any of the foregoing, including taxes or other limitations on our services, may alter the environment in which we do business and, therefore, may impact our results or increase our costs or liabilities. 20 20 21 In certain jurisdictions, we are subject to compliance with specific obligations under competition laws due to our competitive position in those jurisdictions. For example, in May 2002, we entered into an assurance of discontinuance with the Vermont Attorney General’s Office concerning, among other matters, the conduct of our business in Vermont relating to certain contract terms applicable to our small commercial container customers. In August 2011, a revised final judgment of consent and order was entered by the Vermont Superior Court Washington Unit, Civil Division, as a result of some of our small commercial container customers having been mistakenly issued contracts that did not strictly comply with the terms of the assurance of discontinuance. Pursuant to the order, we paid a civil penalty in an aggregate amount of $1.0 million. In July 2014, we entered into an assurance of discontinuance with the office of the New York Attorney General in connection with certain of our commercial practices in certain specified counties in New York, pursuant to which we paid the State of New York a sum of $0.1 million. The assurances of discontinuance and order provide for certain restrictions on our customer contract terms, certain conditions on our business acquisitions, sales and market share and require us to maintain an internal compliance program. Failure to comply with these requirements or other laws or regulations could subject us to enforcement actions or financial penalties which could have a material adverse effect on our business.Our results of operations are affected by low commodity prices and diminished markets for recyclable materials.Our results of operations have been and will continue to be affected by falling purchase or resale prices or market requirements for recyclable materials. Our recycling business involves the purchase and sale of recyclable materials, some of which are priced on a commodity basis. The commodity markets continue to see ongoing negative pressure on pricing associated with the decline of the fiber market due to less use of paper products such as newspaper and office paper as a result of increased on-line reading. As a result of these market changes, domestic demand for various recycled fibers from mill buyers has steadily declined over the past decade, and as such we have exported more of these materials overseas to China. In 2017, China launched a campaign called National Sword which has imposed significant restrictions on the importation into China of recyclable materials, including a complete ban on the import into China of mixed paper and new quality standards for contaminants in recyclable materials commencing January 1, 2018. Furthermore, China has issued limited import licenses for its mills to import recyclable commodities, resulting in a decrease of over 50% of imports of recyclable commodities into China. These factors have had a significant impact on our business and have required us to seek alternative export markets for recyclable commodities.In addition, some of the countries that took recyclable commodities following China’s imposition of restrictions, including Indonesia and India, have themselves imposed similar restrictions on U.S. exports, further impacting prices. Although we have restructured many of our recycling contracts to require the respective municipalities to absorb some of the impact of declining commodity prices, these restructured contracts have had the impact of significantly increasing the costs to municipalities for continuing to offer recycling services to their customers. In the event that the costs of such services becomes excessive, such municipalities could discontinue their recycling programs altogether, which could materially affect our financial results. We seek to limit our exposure to fluctuating commodity prices through: our revenue sharing contracts that share commodity prices above a threshold level or charge a tipping fee below the threshold; our net commodity rate formula that allows us to pass back higher costs to sell commodities, including higher labor costs or equipment costs to meet new quality standards; our floating Sustainability Recycling Adjustment fee that passes back the cost of recycling to our collection customers; and as applicable, the use of hedging agreements, floor price contracts and long-term supply contracts with customers. Although we have introduced these risk mitigation programs to help offset volatility in commodity prices and to offset higher labor or capital costs to meet more stringent contamination standards, we cannot provide assurance that we can use these programs with our customers in all circumstances or that they will mitigate these risks in an evolving recycling environment.Our business requires a high level of capital expenditures.Our business is capital intensive. Our capital expenditure requirements include fixed asset purchases and capital expenditures for landfill development and cell construction, as well as site and cell closure. We use a substantial portion of our cash flows from operating activities toward capital expenditures, which reduces our flexibility to use such cash flows for other purposes, such as reducing our indebtedness. Our capital expenditures could increase if we make acquisitions or further expand our operations, or as a result of factors beyond our control, such as changes in federal, state or local governmental requirements. The amount that we spend on capital expenditures may exceed current expectations, which may require us to obtain additional funding for our operations or impair our ability to grow our business.Table of Contents21Table of Contents We are upgrading our technology infrastructure and there can be no assurance that our efforts will be completed on the projected timetable or that our investment will result in the expected gains. We are upgrading our technology infrastructure, including a limited pilot of a new service management system and other systems that we believe will improve our internal processes and the productivity of our employees. These upgrades are complex and there can be no assurance that they will result in expected productivity gains and operating cost reductions on our anticipated timeline, if at all. In addition, if we are not able to maintain the security of our data, confidential information about us or our customers or suppliers could be inadvertently disclosed, subjecting us to possible expenses and other liabilities as well as adversely impacting customer and other third party relationships. If we are unable to benefit from new technologies, we may be at a competitive disadvantage to other companies in the waste management industry, in which case our operating results could suffer. Cybersecurity incidents could negatively impact our business and our relationships with customers, adversely affecting our financial results and exposing us to litigation risk. We use computer technology in substantially all aspects of our business operations. We also use mobile devices, social networking and other online activities to connect with our customers and our employees to be able to process transactions and provide information that we feel is necessary to manage our business. Such uses give rise to cybersecurity risks, including security breach, espionage, system disruption, theft and inadvertent release of information. Our business involves the storage and transmission of numerous classes of sensitive and/or confidential including customers’ personal information, private information about employees, and financial and strategic information about us and our business partners. We also rely on a Payment Card Industry compliant third party to protect our customers’ credit card information. Further, as we pursue our strategy to grow through acquisitions and to pursue new initiatives that improve our operations and cost structure, we are also expanding and improving our information technologies, resulting in a larger technological presence and corresponding exposure to cybersecurity risk. If we fail to assess and identify cyber security risks associated with acquisitions and new initiatives, we may become increasingly vulnerable to such risks. Additionally, while we have implemented measures to prevent security breaches and cyber incidents, our preventive or detection measures and incident response efforts may not be entirely effective, especially as cyber security attacks continue to evolve and become more sophisticated, often are not recognized until launched against a target and may be difficult to detect for a long time. information and intellectual property, If company, personal or otherwise protected information is improperly accessed, tampered with or distributed, we may face significant financial exposure, including incurring significant costs to remediate possible injury to the affected parties. We may also be subject to sanctions and civil or criminal penalties if we are found to be in violation of the privacy or security rules under laws protecting confidential information. If our established network of security controls, policy enforcement mechanisms, educational awareness programs and monitoring systems that we use to address these threats to technology fail, the theft, destruction, loss, misappropriation, or release of sensitive and/or confidential information or intellectual property, or interference with our information technology systems or the technology systems of third parties on which we rely, could result in business disruption, negative publicity, brand damage, violation of privacy laws, loss of customers, potential litigation and liability and competitive disadvantage. While we have purchased insurance coverage for cybersecurity risks, there can be no assurance that any such coverage would be adequate to cover potential liability. Our business is geographically concentrated and is therefore subject to regional economic downturns. Our operations and customers are concentrated principally in New England and New York. Therefore, our business, financial condition and results of operations are susceptible to regional economic downturns and other regional factors, including state regulations and budget constraints and severe weather conditions. In addition, as we seek to expand in our existing markets, opportunities for growth within this region will become more limited and the geographic concentration of our business will increase. Our results of operations and financial condition may be negatively affected if we inadequately accrue for final capping, closure and post-closure costs or by the timing of these costs for our waste disposal facilities. We have material financial obligations relating to final capping, closure and post-closure costs of our existing owned or operated landfills and will have material financial obligations with respect to any disposal facilities that we may own or operate in the future. Once the permitted capacity of a particular landfill is reached and additional capacity is not authorized, or a determination is made to cease operations at a landfill due to other considerations, the landfill must be closed and capped, and we must begin post-closure maintenance. We establish accruals for the estimated costs associated with such final capping, closure and post-closure obligations over the anticipated useful life of each landfill on a per ton basis. We have provided and expect that we will in the future provide accruals for financial obligations relating to final capping, closure and post-closure costs of our owned or operated landfills, generally for a term of 30 years after closure of a landfill. Our financial obligations for final capping, closure or post-closure costs could exceed the amounts accrued or amounts otherwise receivable pursuant to trust funds established for this purpose. Such a circumstance could result in significant unanticipated charges that would have an adverse effect on our business. 22 22 23 In addition, the timing of any such final capping, closure or post-closure costs, which exceed established accruals, may further negatively affect our business. Since we will be unable to control the timing and amounts of such costs, we may be forced to delay investments or planned improvements in other parts of our business or we may be unable to meet applicable financial assurance requirements. Any of the foregoing would negatively affect our business and results of operations.Fluctuations in fuel costs could affect our operating expenses and results.The price and supply of fuel is unpredictable and fluctuates based on events beyond our control, including among others, geopolitical developments, supply and demand for oil and gas, actions by the Organization of the Petroleum Exporting Countries and other oil and gas producers, war and unrest in oil producing countries and regional production patterns. Because fuel is needed to run our fleet of trucks, price escalations for fuel increase our operating expenses. In fiscal year 2019, we used approximately 6.5 million gallons of diesel fuel in our solid waste operations. Although we have an Energy and Environmental fee program, which includes an Energy component that floats on a monthly basis based on diesel fuel prices, contractual restrictions and competitive conditions may impact our opportunity to pass this fee on to our customers in all circumstances.Our insurance coverage and self-insurance reserves may be inadequate to cover all significant risk exposures.We carry a range of insurance policies intended to protect our assets and operations, including general liability insurance, property damage and environmental risk insurance. While we endeavor to purchase insurance coverage appropriate to our risk assessment, we are unable to predict with certainty the frequency, nature or magnitude of claims for direct or consequential damages, and as a result our insurance program may not fully cover us for losses we may incur. In addition, as a result of a number of catastrophic weather and other events in the United States, insurance companies have incurred substantial losses and accordingly in many cases they have substantially reduced the nature and amount of insurance coverage available to the market, have broadened exclusions, and/or have substantially increased the cost of such coverage. It is likely that the tight insurance market will continue into the foreseeable future. A partially or completely uninsured claim against us (including liabilities associated with cleanup or remediation at our facilities), if successful and of sufficient magnitude, could have a material adverse effect on our business, financial condition and results of operations. Any future difficulty in obtaining insurance could also impair our ability to secure future contracts, which may be conditioned upon the availability of adequate insurance coverage. In addition, claims associated with risks we have retained under our self-insurance programs may exceed our recorded reserves which could negatively impact future earnings.We could be precluded from entering into contracts or obtaining or maintaining permits or certain contracts if we are unable to obtain third-party financial assurance to secure our contractual obligations.Public solid waste collection, recycling and disposal contracts, and obligations associated with landfill closure and post-closure typically require performance or surety bonds, letters of credit or other means of financial assurance to secure our contractual performance. We currently obtain performance and surety bonds from Evergreen National Indemnity Company, in which we hold a 19.9% equity interest. If we are unable to obtain the necessary financial assurance in sufficient amounts or at acceptable rates, we could be precluded from entering into additional municipal contracts or from obtaining or retaining landfill management contracts or operating permits. We may be required to write-off or impair capitalized costs or intangible assets in the future or we may incur restructuring costs or other charges, each of which could harm our earnings.In accordance with generally accepted accounting principles in the United States, we capitalize certain expenditures and advances relating to our acquisitions, pending acquisitions, landfills, cost method investments and development projects. In addition, we have considerable unamortized assets. From time to time in future periods, we may be required to incur a charge against earnings in an amount equal to any unamortized capitalized expenditures and advances, net of any portion thereof that we estimate will be recoverable, through sale or otherwise, relating to: (1) any operation or other asset that is being sold, permanently shut down or impaired or has not generated or is not expected to generate sufficient cash flow; (2) any pending acquisition that is not consummated; (3) any landfill or development project that is not expected to be successfully completed; and (4) any goodwill or other intangible assets that are determined to be impaired.In response to such charges and costs and other market factors, we may be required to implement restructuring plans in an effort to reduce the size and cost of our operations and to better match our resources with our market opportunities. As a result of such actions, we would expect to incur restructuring expenses and accounting charges which may be material. Several factors could cause a restructuring to adversely affect our business, financial condition and results of operations. These include potential disruption of our operations, the development of our landfill capacity and recycling technologies and other aspects of our business. Employee morale and productivity could also suffer and result in unintended employee attrition. Any restructuring would require substantial management time and attention and may divert management from other important work. Moreover, we could encounter delays in executing any restructuring plans, which could cause further disruption and additional unanticipated expense.Table of Contents23Table of Contents Our revenues and our operating income experience seasonal fluctuations. Our transfer and disposal revenues historically have been higher in the late spring, summer and early fall months. This seasonality reflects the lower volume of solid waste during the late fall, winter and early spring months primarily 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, Maine and eastern New York during the winter months tends to lower the volume of solid waste generated by commercial and restaurant customers, which is partially offset by increased volume from the ski industry. Since certain of our operating and fixed costs remain constant throughout the fiscal year, operating income is impacted by a similar seasonality. In addition, particularly harsh weather conditions typically result in increased operating costs. Adverse weather conditions may limit our operations and increase the costs of collection and disposal. Our collection and landfill operations could be adversely impacted by extended periods of inclement weather, or by increased severity of weather. Adverse weather 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. In addition, adverse weather conditions may result in the temporary suspension of our operations, which can significantly affect our operating results in the affected regions during those periods. Efforts by labor unions to organize our employees could divert management attention and increase our operating expenses. Certain groups of our employees have chosen to be represented by unions, and we have negotiated collective bargaining agreements with these groups. The negotiation of collective bargaining agreements could divert management attention and result in increased operating expenses and lower net income (or increased net loss). If we are unable to negotiate acceptable collective bargaining agreements, we may be subject to union-initiated work stoppages, including strikes. Depending on the type and duration of any labor disruptions, our revenues could decrease and our operating expenses could increase, which could adversely affect our financial condition, results of operations and cash flows. As of January 31, 2020, approximately 6% of our employees were represented by unions. Our enterprise risk management process may not be effective in mitigating the risks to which we are subject, or in reducing the potential for losses in connection with such risks. Our enterprise risk management framework is designed to minimize or mitigate the risks to which we are subject, as well as any losses stemming from such risks. Although we seek to identify, measure, monitor, report, and control our exposure to such risks, and employ a broad and diversified set of risk monitoring and mitigation techniques in the process, those techniques are inherently limited in their ability to anticipate the existence or development of risks that are currently unknown and unanticipated. The ineffectiveness of our enterprise risk management framework in mitigating the impact of known risks or the emergence of previously unknown or unanticipated risks may result in our incurring losses in the future that could adversely impact our financial condition and results of operations. Risks Related to Our Indebtedness We have substantial debt and have the ability to incur additional debt. The principal and interest payment obligations of such debt may restrict our future operations. As of December 31, 2019, we had approximately $522.7 million of outstanding principal indebtedness (excluding approximately $24.5 million of outstanding letters of credit issued under our term loan A facility ("Term Loan Facility") and revolving line of credit facility (“Revolving Credit Facility” and, together with the Term Loan Facility, the "Credit Facility"). The Credit Facility consists of the Term Loan Facility with term loans in the outstanding principal amount of $350.0 million and the Revolving Credit Facility with loans thereunder being available up to an aggregate principal amount of $200.0 million, of which $148.6 million of unused commitments remain under the Revolving Credit Facility, subject to customary borrowing conditions. In addition, the terms of our existing indebtedness permit us to incur additional debt. Our substantial debt, among other things: • requires us to dedicate a substantial portion of any cash flow from operations to the payment of interest and principal due under our debt, which reduces funds available for other business purposes, including capital expenditures and acquisitions; • may place us at a competitive disadvantage compared with some of our competitors that may have less debt and better access to capital resources; and 24 24 25 •limits our ability to obtain additional financing required to fund working capital and capital expenditures and for other general corporate purposes, but does allow us to increase the amount of our debt substantially subject to the conditions in the Credit Facility. Our ability to satisfy our obligations and to reduce our total debt depends on our future operating performance and on economic, financial, competitive and other factors, many of which are beyond our control. Our business may not generate sufficient cash flow, and future financings may not be available to provide sufficient net proceeds, to meet these obligations or to successfully execute our business strategy. The Credit Facility requires us to meet a number of financial ratios and covenants. The Credit Facility contains certain affirmative and negative covenants which, among other things and subject, in certain cases, to certain basket amounts and other exceptions, limit the existence of additional indebtedness, the existence of liens or pledges, certain investments, acquisitions and sales or other transfers of assets, the payment of dividends and distributions and repurchases of equity, prepayments of certain junior indebtedness, and certain other transactions. Our ability to comply with these covenants may be affected by events beyond our control, including prevailing economic, financial and industry conditions. These covenants could have an adverse effect on our business by limiting our ability to take advantage of financing, merger and acquisition or other corporate opportunities. Additionally, the Credit Facility requires, solely for the benefit of the lenders under the Revolving Credit Facility, that we meet financial tests, including, without limitation:•minimum consolidated EBITDA to consolidated cash interest charges ratio; and •maximum consolidated funded debt (net of up to an agreed amount of cash and cash equivalents) to consolidated EBITDA ratio. An event of 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 default under any provision governing our outstanding debt obligations, our secured lenders could proceed against us and against the collateral securing that debt. Risks Related to Our Common StockHolders of our Class A common stock are entitled to one vote per share, and holders of our Class B common stock are entitled to ten votes per share. The lower voting power of the Class A common stock may negatively affect the attractiveness of our Class A common stock to investors and, as a result, its market value. We have two classes of common stock: Class A common stock, which is entitled to one vote per share, and Class B common stock, all of which are beneficially owned by John W. Casella, our Chairman and Chief Executive Officer, and his brother, Douglas R. Casella, a member of our Board of Directors, and which is entitled to ten votes per share. Except for the election of one of our directors and in certain limited circumstances required by applicable law, holders of Class A common stock and Class B common stock vote together as a single class on all matters to be voted on by our stockholders. As of January 31, 2020, an aggregate of 988,200 shares of our Class B common stock, representing 9,882,000 votes, were outstanding. Based on the number of shares of common stock outstanding as of January 31, 2020, the shares of our Class A common stock and Class B common stock beneficially owned by John W. Casella and Douglas R. Casella represented approximately 18.9% of the aggregate voting power of our stockholders. Consequently, John W. Casella and Douglas R. Casella are able to substantially influence all matters for stockholder consideration and constitute, and are expected to continue to constitute, a significant portion of the shares entitled to vote on all matters requiring approval by our stockholders. The difference in the voting power of our Class A common stock and Class B common stock could diminish the market value of our Class A common stock if investors attribute value to the superior voting rights of our Class B common stock and the power those rights confer.ITEM 1B. UNRESOLVED STAFF COMMENTSNone.Table of Contents25Table of Contents ITEM 2. PROPERTIES Our headquarters is located at 25 Greens Hill Lane, Rutland, Vermont 05701, where we currently lease approximately 12,000 square feet of office space. Our principal property and equipment consists of land, landfills, buildings, machinery and equipment, rolling stock and containers. At January 31, 2020, we operated eight subtitle D landfills, four of which we own and four of which we lease; one landfill permitted to accept C&D materials that we own; 58 transfer stations, 32 of which we own, eight of which we lease and 18 of which we operate under a contract; 43 solid waste collection facilities, 25 of which we own, 17 of which we lease and one of which we operate under a contract; 20 recycling processing facilities, ten of which we own, seven of which we lease and three of which we operate under a contract; four landfill gas-to-energy facilities that we own; and 25 corporate office and other administrative facilities, five of which we own and 20 of which we lease (See Item 1, “Business” of this Annual Report on Form 10-K for property information by operating segment and location). We believe that our property and equipment are adequately maintained and sufficient for our current operations. ITEM 3. 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. Environmental Remediation Liability (including related litigation) 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 our material outstanding claims. Southbridge Recycling & Disposal Park, Inc. In October 2015, our Southbridge Recycling and Disposal Park, Inc. (“SRD”) subsidiary reported to the Massachusetts Department of Environmental Protection (“MADEP”) 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 SRD 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 are carrying out an Immediate Response Action pursuant to Massachusetts General Law Chapter 21E (the "Charlton 21E Obligations") pursuant to state law. Further, we have implemented a plan to analyze and better understand the groundwater near the Southbridge Landfill and we are investigating with the objective of identifying the source or sources of the elevated levels of contamination measured in the well samples. If it is determined that some or all of the contamination originated at the Southbridge Landfill, we will work with the Town (the Southbridge Landfill owner and the former operator of an unlined portion of the Southbridge Landfill, which was used prior to our operation of a double-lined portion of the Southbridge Landfill commencing in 2004) to evaluate and allocate the liabilities related to the Charlton 21E Obligations. In July 2016, we sent correspondence to the Town pursuant to Chapter 21E of Massachusetts General Laws demanding that the Town reimburse us for the environmental response costs we had spent and that the Town be responsible for all such costs in the future, as well as any other costs or liabilities resulting from the release of contaminants from the unlined portion of the Southbridge Landfill. The Town responded in September 2016, denying that the Southbridge Landfill is the source of such contamination, and claiming that if it is, that we may owe an indemnity to the Town pursuant to the Operating Agreement between us and the Town dated May 29, 2007, as amended. We entered into a Tolling Agreement with the Town to delay any further administrative or legal actions until our work with MADEP more specifically defines the parties’ responsibilities for the Charlton 21E Obligations, if any. Please see below for further discussion of our relationship with the Town regarding the Charlton 21E Obligations. 26 26 27 In February 2016, we and the Town received a Notice of Intent to Sue under the Resource Conservation and Recovery Act ("RCRA") from a law firm purporting to represent residents proximate to the Southbridge Landfill (“Residents”), indicating its intent to file suit against us on behalf of the Residents alleging the groundwater contamination originated from the Southbridge Landfill. In February 2017, we received an additional Notice of Intent to Sue from the National Environmental Law Center under the Federal Clean Water Act ("CWA") and RCRA (collectively the “Acts”) on behalf of Environment America, Inc., d/b/a Environment Massachusetts, and Toxics Action Center, Inc., which have referred to themselves as the Citizen Groups. The Citizen Groups alleged that we had violated the Acts, and that they intended to seek appropriate relief in federal court for those alleged violations. On or about June 9, 2017, a lawsuit was filed against us, SRD and the Town in the United States District Court for the District of Massachusetts (the “Massachusetts Court”) by the Citizen Groups and the Residents alleging violations of the Acts (the “Litigation”), and demanding a variety of remedies under the Acts, including fines, remediation, mitigation and costs of litigation, and remedies for violations of Massachusetts civil law related to personal and property damages, including remediation, diminution of property values, compensation for lost use and enjoyment of properties, enjoinment of further operation of the Southbridge Landfill, and costs of litigation, plus interest on any damage award, on behalf of the Residents. We believe the Litigation to be factually inaccurate, and without legal merit, and we and SRD intend to vigorously defend the Litigation. Nevertheless, we believe it is reasonably possible that a loss will occur as a result of the Litigation although an estimate of loss cannot be reasonably provided at this time. We also continue to believe the Town should be responsible for costs or liabilities associated with the Litigation relative to alleged contamination originating from the unlined portion of the Southbridge Landfill, although there can be no assurance that we will not be required to incur some or all of such costs and liabilities.In December 2017, we filed a Motion to Dismiss the Litigation, and on October 1, 2018, the Massachusetts Court granted our Motion to Dismiss, and accordingly, dismissed the Citizen Groups claims under the Acts. The Massachusetts Court has retained jurisdiction of the Residents claims. The Citizen Groups intend to appeal the Massachusetts Court’s decision to grant our Motion to Dismiss. The Residents moved for a stay of their case until the Citizen Groups appealed. We opposed the stay and in March 2019, the Massachusetts Court denied the Residents motion for a stay. We are in active discovery in the Residents case.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 $10.0 million ($5.0 million 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 will issue a twenty (20) year bond for our portion of the Waterline costs (up to $5.0 million). 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. Remaining aspects of the project are minor and are expected to be completed in early 2020. Bond reimbursement to the Town will commence in the fiscal year ending December 31, 2020.We have recorded an environmental remediation liability related to our obligation associated with the 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 of 1.9%. A summary of the changes to the environmental remediation liability associated with the Southbridge Landfill follows (in millions): Twelve Months Ended December 31, 2019 20192018Beginning balance$5.2$5.9Accretion expense0.1—Obligations incurred—0.2Obligations settled (1)(0.7)(0.9)Ending balance$4.6$5.2(1)Includes amounts that are being processed through accounts payable as a part of our disbursements cycle.We completed the first phase of landfill capping and closure at the Southbridge Landfill in the fiscal year ended December 31, 2019, and are actively seeking approval from MADEP to close and cap the remainder of the landfill.The costs and liabilities we may be required to incur in connection with the foregoing Southbridge Landfill matters could be material to our results of operations, our cash flows and our financial condition.Table of Contents2728 Potsdam Environmental Remediation LiabilityOn 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 (“GM”) 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 $10.2 million. 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 $12.1 million. 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 was completed in the fiscal year ended December 31, 2019. 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. Our expenditures could be significantly higher if costs exceed estimates. 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 1.5%.A summary of the changes to the environmental remediation liability associated with the Potsdam site follows (in millions): Twelve Months Ended December 31, 2019 20192018Beginning balance$5.6$5.8Obligations incurred (1)(4.5)(0.2)Ending balance$1.1$5.6(1)Includes amounts that are being processed through accounts payable as a part of our disbursements cycle.Legal ProceedingsNorth Country Environmental ServicesOn or about March 8, 2018, the Citizen Groups described above delivered correspondence to our subsidiary, North Country Environmental Services, Inc. ("NCES") and us, providing notice of the 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 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. On June 15, 2018, we and NCES filed a Motion to Dismiss the New Hampshire Litigation. On July 13, 2018, the 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 circuits were heard by the Supreme Court of the United States (“SCOTUS”). SCOTUS has granted certiorari determining that the circumstances described are sufficient for SCOTUS to hear such cases. Our motion for a stay was granted in the New Hampshire Litigation, and SCOTUS is expected to hear and rule on such cases this calendar year. In any event, we intend to continue to vigorously defend against the New Hampshire Litigation, which we believe is without merit.Table of Contents2829 Ontario County, New York Class Action LitigationOn or about September 17, 2019, Richard Vandemortel and Deb Vandemortel filed a class action complaint against us on behalf of similarly situated citizens in Ontario County, New York. The lawsuit has been filed in Ontario County (the “New York Litigation”). It 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 Ontario County Landfill, 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. We are reviewing the New York Litigation and intend to present a vigorous defense.ITEM 4.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSThe following discussion of our financial condition and results of operations should be read in conjunction with the consolidated financial statements and notes thereto, and other financial information, included elsewhere in this Annual Report on Form 10-K. This discussion contains forward-looking statements and involves numerous risks and uncertainties. Our actual results may differ materially from those contained in any forward-looking statements.Discussion and analysis of the fiscal year ended December 31, 2018 compared to the fiscal year ended December 31, 2017 is included under the heading “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 as filed with the Securities and Exchange Commission on February 22, 2019.Company OverviewFounded 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-integrated solid waste services company. We provide resource management expertise and services to residential, commercial, municipal 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 six states: Vermont, New Hampshire, New York, Massachusetts, Maine and Pennsylvania, with our headquarters located in Rutland, Vermont. We have managed operations through four operating segments, including (i) two regional operating segments, which we designate as our Eastern and Western regions, (ii) Recycling, which comprises our larger-scale recycling operations and our commodity brokerage operations and (iii) "Other", which comprises organic services, ancillary operations, along with major accounts and industrial services. Effective January 1, 2020, we reorganized our operating segments as follows: we aligned our organics services and our major account and industrial services with our Recycling segment to form the Resource Solutions segment, thus creating a single resource renewal-focused segment. We also moved our ancillary transportation services, which were previously included in our Other segment, into our Western region. Accordingly, as of January 1, 2020, our operating segments consist of the Eastern and Western regions and Resource Solutions.As of January 31, 2020, we owned and/or operated 43 solid waste collection operations, 58 transfer stations, 20 recycling facilities, eight Subtitle D landfills, four landfill gas-to-energy facilities and one landfill permitted to accept construction and demolition (“C&D”) materials.Table of Contents3334 Recent DevelopmentsOn January 9, 2019, North Country Environmental Services, Inc. ("NCES") filed an application for a 1.2 million (cy) expansion of the capacity of its landfill in Bethlehem, New Hampshire ("NCES Landfill") with the New Hampshire Department of Environmental Services (“NHDES”) (“Stage VI Expansion”). The Stage VI Expansion would provide NCES with over five (5) years of additional capacity beyond the capacity of Stage V.In January 2020, NHDES informed NCES and us that NHDES had concerns regarding the short-term public benefit need for the Stage VI expansion, and also in respect of certain technical concerns regarding the Stage VI expansion. Given the fact the NHDES decided to review our permit application for the Stage VI Expansion with respect to public benefit determination using a different regulatory framework than used in any of our previous permitting activities at NCES, we informed the NHDES on February 11, 2020, that while we vigorously disagreed with NHDES’ review of our application and the context for the NHDES’ concerns, we would withdraw our application with the expectation of refiling the application with the NHDES as soon as possible. While the refiling of the application for the Stage VI Expansion could be rejected by the NHDES, and while delay of the Stage VI Expansion will surely occur, we remain confident that we will receive a permit for the Stage VI Expansion. We believe that a loss of $1.2 million is reasonably possible, but not probable.Acquisitions and DivestituresAcquisitionsWe have a business development team that identifies acquisition candidates, categorizes the opportunity by strategic fit and perceived level of financial accretion, establishes contact with the appropriate representative of the acquisition candidate and gathers further information on the acquisition candidate.We have made in the past, and we may make in the future, acquisitions in order to acquire or develop additional disposal capacity. These acquisitions may include “tuck-in” acquisitions within our existing markets, assets that are adjacent to or outside of our existing markets, or larger, more strategic acquisitions. In addition, from time to time, we may acquire businesses that are complementary to our core business strategy. We face competition for acquisition targets, particularly the larger and more meaningful targets, but we believe that our strong relationships and reputation in New England and New York help to offset this factor. In the fiscal year ended December 31, 2019 ("fiscal year 2019"), we acquired nine businesses: three tuck-in solid waste collection businesses in our Eastern region and four tuck-in solid waste collection businesses, a business comprised of solid waste collection, transfer and recycling operations, and a business comprised of solid waste hauling and transfer assets in our Western region for total consideration of $82.2 million, including $72.1 million in cash, $5.5 million in non-cash consideration, $2.7 million notes payable and $1.9 million in holdbacks to the sellers.In the fiscal year ended December 31 2018 ("fiscal year 2018"), we acquired nine businesses: six solid waste collection businesses and one transfer business in our Western region and two businesses comprised of solid waste collection and transfer operations in our Eastern region for total consideration of $99.5 million, including $86.7 million in cash, $4.3 million in Class A common stock, and $8.5 million in contingent consideration and holdbacks to the sellers. DivestituresFrom time to time, we may sell or divest certain investments or other components of our business. These divestitures may be undertaken for a number of reasons, including: to generate proceeds to pay down debt; as a result of a determination that the specified asset will provide inadequate returns to us or that the asset no longer serves a strategic purpose in connection with our business; or as a result of a determination that the asset may be more valuable to a third-party. We will continue to look to divest certain activities and investments that no longer enhance or complement our core business if the right opportunity presents itself.Results of Operations Table of Contents3435 RevenuesWe 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 our Eastern and Western regions. Revenues in our Eastern and Western regions consist primarily of fees charged to customers for solid waste collection and disposal, landfill, landfill gas-to-energy, transfer and recycling 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. Revenues from our Recycling segment consist of revenues derived from municipalities and customers in the form of processing fees, tipping fees and commodity sales. Revenues from organics services, ancillary operations, and major account and industrial services are included in our Other segment. Our revenues are shown net of inter-company eliminations.The table below shows revenue attributable to services provided (in millions) for the following periods: Fiscal Year Ended December 31,$Change 20192018Collection$372.0$303.4$68.6Disposal181.9181.10.8Power3.65.1(1.5)Processing7.27.2—Solid waste564.7496.867.9Organics56.354.22.1Customer solutions79.567.512.0Recycling42.842.20.6Total revenues$743.3$660.7$82.6Solid waste revenuesA summary of the period-to-period change in solid waste revenues (dollars in millions and as percentage growth of solid waste revenues) follows:Period-to-Period Change for Fiscal Year 2019 vs Fiscal Year 2018 Amount% GrowthPrice$25.35.1%Volume(5.1)(1.0)%Surcharges and other fees5.01.0%Commodity price and volume(3.7)(0.7)%Acquisitions57.911.6%Closed operations(10.5)(2.1)%Solid waste revenues$68.913.9%(1)Adjusted for $1.0 million of inter-company movements between solid waste collection volume and Customer Solutions associated with the acquisition of a business.Price. The price change component in fiscal year 2019 solid waste revenues growth from the prior year is a result of the following:•$16.2 million from favorable collection pricing; and•$9.1 million from favorable disposal pricing associated primarily with our landfills and transfer stations.Table of Contents3536 Volume.The volume change component in fiscal year 2019 solid waste revenues growth from the prior year is a result of the following:•$(2.6) million from lower collection volumes as we continue to focus on pricing and the quality of revenue; •$(2.1) million from lower disposal volumes (of which $(5.6) million relates to lower transportation volumes primarily associated with a large contaminated soils project that occurred in fiscal year 2018, $1.8 million relates to higher landfill volumes, and $1.7 million relates to higher transfer station volumes); and•$(0.4) million from lower processing volumes.Surcharges and other fees.The surcharges and other fees change component in fiscal year 2019 solid waste revenues growth from the prior year is associated primarily with the Energy component of the Energy and Environmental fee and the Sustainability Recycling Adjustment fee. The Energy component of the fee floats on a monthly basis based on diesel fuel prices. The Sustainability Recycling Adjustment fee floats on a monthly basis based on recycled commodity prices.Commodity price and volume.The commodity price and volume change component in fiscal year 2019 solid waste revenues growth from the prior year is a result of the following:•$(1.2) million from unfavorable energy pricing and, to a lesser extent, unfavorable commodity pricing; and•$(2.5) million from lower commodity volumes due to lower commodity processing volumes and landfill gas-to-energy production.Acquisitions.The acquisitions change component in fiscal year 2019 solid waste revenues growth is a result of increased acquisition activity, including the following:•the acquisition of nine businesses in fiscal year 2019: seven tuck-in solid waste collection businesses, a business comprised of solid waste collection, transfer and recycling operations, and a business comprised of solid waste hauling and transfer assets; and•the acquisition of nine businesses in fiscal year 2018: six tuck-in solid waste collection businesses, one transfer business, and two businesses comprised of solid waste collection and transfer operations, combined to a lesser extent with roll over impact of acquisitions made in fiscal year 2017.Closed operations.The closed operations change component in fiscal year 2019 total solid waste revenues growth from prior year is a result of the closure of the landfill located in Southbridge, Massachusetts ("Southbridge Landfill") in our Eastern region in the quarter ended December 31, 2018 and the closure of a transfer station in our Western region in the quarter ended March 31, 2019.Organics revenuesFiscal year 2019 organics revenues increased $2.1 million from the prior year as a result of higher volumes associated with two large transportation and disposal contracts.Customer Solutions revenuesFiscal year 2019 revenues increased $11.0 million from the prior year as a result of higher volumes mainly due to multi-site retail and industrial services organic growth.Recycling revenuesFiscal year 2019 recycling revenues increased $0.6 million from the prior year as a result of the following:•$8.0 million from higher recycling processing fees; and•$1.1 million from higher commodity volumes; partially offset by•$(8.5) million from unfavorable commodity pricing in the marketplace.Table of Contents3637 Operating ExpensesA summary of our cost of operations, general and administration expenses and depreciation and amortization expenses is as follows (dollars in millions and as a percentage of total revenues): Fiscal Years Ended December 31, 20192018 Cost of operations$508.768.4%$453.368.6%General and administration$92.812.5%$84.812.8%Depreciation and amortization$79.810.7%$70.510.7%Cost of OperationsCost 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.An explanation of the period-to-period change in cost of operations is as follows:Third-party direct costs in fiscal year 2019 increased $25.8 million from the prior year as a result of the following: •higher disposal costs associated with: additional volumes related to acquisition activity; additional volumes related to multi-site retail and industrial services organic growth in our Customer Solutions line-of-business; increased disposal pricing in the northeastern United States; and an increased reliance on third-party disposal sites in our Organics line-of-business during the first half of the fiscal year; and•higher hauling and third-party transportation costs associated with: higher collection volumes related to acquisition activity; higher transportation rates; and higher brokerage volumes in our Customer Solutions line-of-business with high pass through direct costs; partially offset by lower hauling and third-party transportation costs in the Western region associated with lower transportation volumes related to a large contaminated soils project that occurred in the prior year.Labor and related benefit costs in fiscal year 2019 increased $15.9 million from the prior year due to higher labor costs related primarily to acquisition activity and wage increases associated with tight labor markets.Maintenance and repair costs in fiscal year 2019 increased $13.3 million from the prior year due primarily to higher fleet and facility maintenance costs associated with acquisition activity and related business growth.Fuel costs in fiscal year 2019 increased $2.8 million from the prior year due primarily to higher volumes associated with acquisition activity.Direct operational costs in fiscal year 2019 decreased $(2.4) million from the prior year due to lower landfill operating lease amortization and lower host royalty fees driven primarily by the closure of the Southbridge Landfill in the Eastern region; lower rent expense associated with operating leases; and lower landfill operating costs; partially offset by higher auto insurance costs associated primarily with claims activity.General and AdministrationGeneral and administration expenses include management, clerical and administrative compensation and overhead, professional services 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 higher labor and related benefit costs associated with acquisition activity and higher accrued incentive compensation, partially offset by lower equity compensation costs and lower professional service fees related to reduced legal costs and consulting fees.Table of Contents3738 Depreciation and AmortizationDepreciation 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.A summary of the components of depreciation and amortization expense (dollars in millions and as a percentage of total revenues) follows:Fiscal Year Ended December 31, 20192018 Depreciation expense$45.16.1%$35.45.4%Landfill amortization expense27.53.7%31.84.8%Other amortization expense7.20.9%3.30.5%$79.810.7%$70.510.7%The period-to-period change in depreciation and amortization expense can be primarily attributed to acquisition activity, partially offset by lower landfill amortization expense associated with lower landfill volumes in our Eastern Region due to the closure of the Southbridge Landfill.Multiemployer Pension PlanWe make contributions to a multiemployer defined benefit pension plan, the New England Teamsters and Trucking Industry Pension Fund (the “Pension Plan”), under the terms of a collective bargaining agreement (“CBA”) that covers certain of our union represented employees. The Pension Plan provides retirement benefits to participants based on their service to contributing employers. We do not administer the Pension Plan. The risks of participating in a multiemployer pension plan are different from a single-employer pension plan in that: (i) assets contributed to the multiemployer pension plan by one employer may be used to provide benefits to employees or former employees of other participating employers; (ii) if a participating employer stops contributing to the plan, the unfunded obligations of the plan may be required to be assumed by the remaining participating employers; and (iii) if we choose to stop participating in our multiemployer Pension Plan, we may be required to pay the plan a withdrawal amount based on the underfunded status of the plan.In October 2019, we reached an agreement to withdraw from the Pension Plan by entering into Withdrawal and Re-entry Agreements with the Pension Plan. In accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 450 - Contingencies, because of our withdrawal from the Pension Plan, we recorded an obligation of $3.2 million as of September 30, 2019 and a charge of $3.6 million as pension withdrawal expense, offset by a $0.4 million retroactive contribution credit recorded as cost of operations, in fiscal year 2019. While the withdrawal generates a fixed yearly contingent liability for us for a period of approximately seventeen (17) years, it caps our gross payments at $4.2 million, significantly reducing our cash exposure from the potential $18.5 million withdrawal liability as determined based on a complete withdrawal. As per the Re-entry Agreements and upon withdrawal, we re-entered the Pension Plan with certainty from a liability perspective. We have not, however, changed the terms of our CBA with Local 170, which remains in effect until June 30, 2020. As of December 31, 2019, we had a remaining obligation of $1.8 million associated with our withdrawal.Table of Contents3839 Southbridge Landfill Closure Charge, NetIn June 2017, we initiated the plan to cease operations of our Southbridge Landfill and later closed it in November 2018 when Southbridge Landfill reached its final capacity. In fiscal years 2019 and 2018, we recorded charges associated with the closure of our Southbridge Landfill as follows: Fiscal Year Ended December 31, 20192018Contract settlement charge (1)$—$8.7Landfill closure project charge (2)—6.0Charlton settlement charge (3)—1.2Legal and transaction costs (4)2.72.2Recovery on insurance settlement (5)—(10.0)Southbridge Landfill closure charge, net$2.7$8.1(1)We recorded a contract settlement charge associated with the closure of Southbridge Landfill and the remaining future obligations due to the Town of Southbridge under the landfill operating agreement with the Town of Southbridge. (2)We recorded a landfill closure project charge associated with increased costs under the revised closure plan at our Southbridge Landfill.(3)We established a reserve associated with settlement of the Town of Charlton's claim against us. (4)We incurred legal and other transaction costs associated with various matters as part of the Southbridge Landfill closure. (5)We recorded a recovery on an environmental insurance settlement associated with the Southbridge Landfill closure. Expense from Acquisition Activities and Other ItemsIn fiscal year 2019, we recorded a charge of $2.7 million associated primarily with acquisition activities. In fiscal year 2018, we recorded a charge of $1.9 million associated with acquisition activities and the write-off of deferred costs related to the expiration of our shelf registration statement. See Note 5, Business Combinations to our consolidated financial statements included under Part II, Item 8 of this Annual Report on Form 10-K for disclosure regarding acquisition activity.Contract Settlement Charge In fiscal year 2018, we recorded contract settlement charges of $2.1 million associated with the termination and discounted buy-out of a commodities marketing and brokerage agreement. Development Project Charge In fiscal year 2018, we recorded development project charges of $0.3 million associated with previously deferred costs that were written off as a result of the negative vote in a public referendum relating to the NCES Landfill.Other expensesInterest Expense, netOur interest expense, net decreased $(1.3) million in fiscal year 2019 due primarily to lower average interest rates, lower average debt balances and the refinancing of our term loan B facility ("Term Loan B Facility") with our existing revolving line of credit facility ("Revolving Credit Facility") and our term loan A facility ("Term Loan Facility", together with the Revolving Credit Facility, the "Credit Facility"), and the remarketing of our Vermont Economic Development Authority Solid Waste Disposal Long-Term Revenue Bonds Series 2013 ("Vermont Bonds") and our New York State Environmental Facilities Corporation Solid Waste Disposal Revenue Bonds Series 2014 ("New York Bonds 2014").Loss on Debt ExtinguishmentIn order to lower our borrowing costs and reduce our market risk we completed the following transactions that resulted in a loss on debt extinguishment in fiscal year 2018 of $7.4 million:•the write-off of debt issuance costs and unamortized discount, in the case of our Term Loan B Facility in fiscal year 2018, associated with the refinancing of our previously outstanding senior secured credit facility in fiscal year 2018: and•the write-off of debt issuance costs in connection with the remarketing of our Vermont Bonds in fiscal year 2018.Table of Contents3940 Impairment of InvestmentsAs of December 31, 2018, we owned 6.8% of the outstanding common stock of Recycle Rewards, Inc. (“Recycle Rewards”), a company that marketed an incentive based recycling service. In fiscal year 2018, it was determined based on the operating performance of Recycle Rewards that our cost method investment in Recycle Rewards was potentially impaired. As a result, we performed a valuation analysis in fiscal year 2018, which used an income approach based on discounted cash flows to determine an equity value for Recycle Rewards in order to properly value our cost method investment in Recycle Rewards. Based on this analysis, it was determined that the fair value of our cost method investment in Recycle Rewards was less than the carrying amount and, therefore, we recorded an other-than-temporary investment impairment charge for the full cost method investment amount of $1.1 million in fiscal year 2018. In October 2019, Recycle Rewards sold all or substantially all of its assets comprising the business to RTS RecycleBank, LLC, a subsidiary of Recycle Track Systems, pursuant to an asset purchase agreement. Based on our junior ownership position, we did not receive any proceeds from this disposition.Benefit for Income TaxesOur benefit for income taxes was $(1.9) million in fiscal year 2019 and $(0.4) million in fiscal year 2018. The benefit for income taxes for fiscal years 2019 and 2018 include a deferred tax (benefit) provision of $(1.2) million and $1.3 million, respectively. During fiscal years 2019 and 2018, we recognized $(2.4) million and $(0.9) million of deferred tax benefits, respectively, due to a reduction of the valuation allowance. The valuation allowance decreased in the periods based upon the recognition of additional reversing temporary differences related to the $2.4 million deferred tax liability recorded through goodwill for the acquisition of a company in May 2019 and $0.9 million deferred tax liability recorded through goodwill for the acquisition of two companies in January 2018. The deferred tax liabilities related to the acquisitions were based on the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and the related tax bases. Deferred tax benefits of $(2.1) million and $(1.6) million were recognized in the quarters ended June 30, 2019 and March 31, 2018, respectively, based on initial estimates of the acquired temporary differences, and adjusted by $(0.3) million in the quarter ended December 31, 2019 and by $0.7 million in subsequent quarters of fiscal year 2018 based on the availability of better estimates of temporary differences upon the filing of prior year returns by the sellers.During fiscal year 2019, we recognized a $(0.3) million deferred tax benefit due to a reduction of the deferred tax liability related to indefinite lived assets. The financial statement value of indefinite lived goodwill was reduced as a result of a settlement of an acquisition contingency that pre-dated the effective date of ASC 805, which resulted in a reduction of the related deferred tax liability. On December 22, 2017, the Tax Cuts and Jobs Act (the “Act”) was enacted. The Act, which is also commonly referred to as “US tax reform,” significantly changed US corporate income tax laws by, among other things, reducing the US corporate income tax rate from 35% to 21% starting in 2018. Under the Act, the alternative minimum tax has been repealed and minimum tax credit carryforwards became refundable beginning in 2018 and will be fully refunded, if not otherwise used to offset tax liabilities, in tax year 2021. Further, our $110.6 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 future tax years. Federal net operating losses generated after 2017, totaling $67.4 million as of fiscal year 2019, are carried forward indefinitely, but generally may only offset up to 80% of taxable income earned in a tax year. In the quarter ending December 31, 2017, we revalued our deferred tax assets and liabilities for changes under the Act including (a) revaluing our federal net deferred taxes assets before valuation allowance using the 21% tax rate; (b) revaluing our federal valuation allowance using the 21% tax rate; and (c) recognizing a federal deferred tax benefit for 80% of indefinite lived deferred tax liabilities, which are anticipated to be available as a source of taxable income upon reversal of deferred tax assets that would also have indefinite lives.The benefit for income taxes for fiscal years 2019 and 2018 incorporates the changes under the Act, including use of the 21% US corporate income tax rate and applying the new federal net operating loss carryforward rules. At the end of 2017, we had $3.8 million of minimum tax credit carryforwards of which $1.0 million is refundable for 2019 and $1.9 million was refunded for 2018. Current income tax benefits of $1.0 million, offset by a $1.0 million deferred tax provision, were recognized in fiscal year 2019 for the minimum tax credit carryforward refundable for the year.Table of Contents4041 Segment ReportingWe report selected information about 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 and disposal, landfill, landfill gas-to-energy, transfer and recycling services in the northeastern United States. Our revenues in the Recycling segment were derived from municipalities and customers in the form of processing fees, tipping fees and commodity sales. Organics services, ancillary operations, along with major account and industrial services, were included in our Other segment. Effective January 1, 2020, we reorganized our operating segments as follows: we aligned our organics services and our major account and industrial services with our Recycling segment to form the Resource Solutions segment, thus creating a single resource renewal-focused segment.

Excluding the impact of expense from acquisition activities and other items and the contract settlement charge associated with the termination and discounted buy-out of a commodities marketing and brokerage agreement in the prior year, our operating performance in fiscal year 2019 improved primarily due to revenue growth on higher commodity volumes and recycling processing fees, combined with lower operating costs, including lower third-party disposal costs and lower purchased material costs on reduced commodity pricing in the marketplace.OtherOther operating income increased by $1.2 million in fiscal year 2019 from the prior year based on the following: •improved operating performance of our Customer Solutions line-of-business, as revenue growth associated with increased volumes outpaced higher cost of operations associated with the corresponding increase in hauling, transportation and disposal costs; and•improved operating performance of our Organics line-of-business, as revenue growth associated with increased volumes, which were driven by two large transportation and disposal contracts, outpaced higher cost of operations as a result of internalizing disposal volumes that were previously directed to third-party sites. This offset the impact of intercompany profits in our Organics line-of-business passing through to landfill disposal sites resulting in lower margins.Table of Contents4445 Liquidity and Capital ResourcesWe continually monitor our actual and forecasted cash flows, our liquidity, and our capital requirements in order to properly manage our cash needs based on the capital intensive nature of our business. Our capital requirements include fixed asset purchases (including capital expenditures for vehicles), debt servicing, landfill development and cell construction, landfill site and cell closure, as well as acquisitions. We generally meet our liquidity needs from operating cash flows and borrowings from our $200.0 million Revolving Credit Facility.A summary of cash and cash equivalents, restricted assets and debt balances, excluding any debt issuance costs, (in millions) follows:December 31,20192018Cash and cash equivalents$3.5$4.0Restricted assets:Restricted investments securities - landfill closure$1.6$1.2Debt:Current portion$4.3$2.3Non-current portion518.4552.9Total debt$522.7$555.2Summary of Cash Flow ActivityA summary of cash flows (in millions) follows: Fiscal Year EndedDecember 31, 20192018Net cash provided by operating activities$116.8$120.8Net cash used in investing activities$(177.5)$(164.2)Net cash provided by financing activities$60.1$45.4Table of Contents4546 Cash flows from operating activities.

This was the result of improved operational performance, being more than offset by the unfavorable cash flow impact associated with the changes in our assets and liabilities, net of effects of acquisitions and divestitures. For discussion over our improved operational performance fiscal year 2019 as compared to fiscal year 2018, see Results of Operations included in Item 7 of this Annual Report on Form 10-K. The $(23.4) million increase in the unfavorable cash flow impact associated with the changes in our assets and liabilities, net of effects of acquisitions and divestitures, which are affected by both cost changes and the timing of payments, in fiscal year 2019 as compared to fiscal year 2018 was due to the following:•a $(13.8) million unfavorable impact to operating cash flows associated with the change in accrued expenses and other liabilities associated primarily with higher final capping, closure and post-closure payments of $4.8 million and higher environmental remediation payments of $4.1 million associated primarily with our Potsdam site. The cash flow impact associated with the changes in our assets and liabilities, net of effects of acquisitions and divestitures was also impacted by changes to the accounting for operating leases as a result of the implementation of Accounting Standards Update No. 2016-02, as amended through March 2019: Leases ("Topic 842") effective January 1, 2019, which are now accounted for as operating lease liabilities on our consolidated balance sheets;•a $(5.3) million unfavorable impact to operating cash flows associated with landfill operating lease contract expenditures being reclassified from investing activities to operating activities within our consolidated statements of cash flows as a result of the implementation of Topic 842; •a $(2.4) million unfavorable impact to operating cash flows associated with the change in accounts payable; and•a $(2.2) million unfavorable impact to operating cash flows associated with cash outflows associated with prepaid expenses, inventories and other assets; partially offset by•a $0.3 million favorable impact to operating cash flows associated with the change in accounts receivable.Table of Contents4647 Cash flows from investing activities.

In fiscal year 2019, we acquired seven tuck-in solid waste collection businesses, a business comprised of solid waste collection, transfer and recycling operations and a business comprised of solid waste hauling and transfer assets for total consideration of $82.2 million, including $72.1 million in cash, and paid $3.3 million in holdback payments on businesses previously acquired, as compared to fiscal year 2018, during which we acquired six solid waste collection businesses, one transfer business and two businesses comprised of solid waste collection and transfer operations for total consideration of $99.5 million, including $86.7 million in cash and $2.2 million in holdback payments on businesses previously acquired. Capital expenditures. Capital expenditures were $29.9 million higher in fiscal year 2019 as compared to fiscal year 2018 primarily due to capital expenditures associated with timing differences, business growth and acquisition activities. Capital expenditures associated with acquisition activities were included as capital investments in our pre-acquisition discounted cash flow analysis and are necessary to integrate operations, drive operating and back-office synergies and bring acquired operations up to our standards. Payments on landfill operating lease contracts. As a result of the implementation of Topic 842, payments on landfill operating lease contracts are classified as operating cash outflows in fiscal year 2019 as compared to investing cash outflows in fiscal year 2018.Proceeds from Southbridge Landfill insurance recovery. We recorded a recovery on environmental insurance settlement associated with the Southbridge Landfill closure, of which $3.5 million related to the recovery of net cash previously used in investing activities.Proceeds from property insurance settlement. Recovery of insurance proceeds was $(0.7) million lower in fiscal year 2019 as compared to fiscal year 2018 due to increased recoveries in prior year pertaining to property damage related to a fire at a transfer station in our Western region.Cash flows from financing activities.

Debt borrowings decreased by $(436.9) million and debt payments decreased by $(340.8) million in fiscal year 2019. The decrease in financing cash flows related to debt activity is associated with paying down our Revolving Credit Facility in fiscal year 2019, partially offset by increased borrowings related to acquisition activity, as compared to fiscal year 2018, when we increased borrowings related to acquisition activity and issued $15.0 million aggregate principal amount of Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2015R-2 (“FAME Bonds 2015R-2”).Payments of debt issuance costs. We made $0.7 million of debt issuance cost payments in fiscal year 2019 related to the remarketing of $11.0 million aggregate principal amount of senior unsecured Solid Waste Disposal Revenue Bonds Series 2013 issued by the Business Finance Authority of the State of New Hampshire ("New Hampshire Bonds") and $25.0 million aggregate principal amount of New York Bonds 2014. In fiscal year 2018, we made $5.6 million of debt issuance cost payments related primarily to the refinancing of our Credit Facility and the issuance of FAME Bonds 2015R-2.Proceeds from the exercise of share-based awards. We received $3.4 million of cash receipts associated with the exercise of stock options in fiscal year 2019 as compared to $0.5 million in fiscal year 2018 due primarily to the appreciation of our stock price.Proceeds from the public offering of Class A Common Stock. In fiscal year 2019, we completed a public offering of 3.6 million shares of our Class A common stock at a public offering price of $29.50 per share. The offering resulted in net proceeds to us of $100.4 million, after deducting underwriting discounts, commissions and offering expenses. The net proceeds from the offering were and are to be used for general corporate purposes, including potential acquisitions or development of new operations or assets with the goal of complementing or expanding our business, working capital and capital expenditures.Proceeds from the unregistered sale of Class A Common Stock. In fiscal year 2019, we completed the unregistered sale of 59,307 shares of our Class A common stock at a price of $44.15 per share. The sale resulted in net proceeds to us of $2.6 million. The shares were previously held in escrow according to the terms of our acquisition of Waste Stream Inc. ("WSI") in 1999 and released to us for liquidation to offset costs associated with the environmental remediation of WSI's Potsdam, New York site. See Note 12, Commitments and Contingencies to our consolidated financial statements included under Part II, Item 8 of this Annual Report on Form 10-K for additional disclosure.Outstanding Long-Term DebtCredit FacilityIn fiscal year 2018, we entered into a credit agreement ("Credit Agreement"), which provides for a $350.0 million aggregate principal amount Term Loan Facility and a $200.0 million Revolving Credit Facility. The net proceeds from this transaction were used to repay in full the amounts outstanding of the Term Loan B Facility and the $160.0 million revolving line of credit facility plus accrued and unpaid interest thereon and to pay related transaction expenses. We have the right to request, at our discretion, an increase in the amount of loans under the Credit Facility by an aggregate amount $125.0 million, subject to the terms and conditions set forth in the Credit Agreement. The Credit Facility has a 5-year term and bears interest at a rate of LIBOR plus 1.75%, which can be reduced to a rate of LIBOR plus 1.25% upon us reaching a consolidated net leverage ratio of less than 2.25x. 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 December 31, 2019, further advances were available under the Credit Facility in the amount of $148.6 million. The available amount is net of outstanding irrevocable letters of credit totaling $24.5 million, at which date 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 December 31, 2019, we were in compliance with all financial covenants contained in the Credit Agreement as follows (in millions):Credit Facility CovenantFiscal Year Ended December 31, 2019Covenant Requirements at December 31, 2019Maximum consolidated net leverage ratio (1)3.074.50Minimum interest coverage ratio7.333.00 Table of Contents4849 (1)The maximum consolidated net leverage ratio is calculated as consolidated funded debt, net of unencumbered cash and cash equivalents in excess of $2.0 million (calculated at $521.3 million as of December 31, 2019, or $522.7 million of consolidated funded debt less $1.4 million of cash and cash equivalents in excess of $2.0 million as of December 31, 2019), divided by minimum consolidated EBITDA. Minimum consolidated EBITDA is based on operating results for the twelve months preceding the measurement date of December 31, 2019. Consolidated funded debt, net unencumbered cash and cash equivalents in excess of $2.0 million, and minimum consolidated EBITDA are non-GAAP financial measures that should not be considered an alternative to any measure of financial performance calculated and presented in accordance with generally accepted accounting principles in the United States. A reconciliation of minimum consolidated EBITDA to net cash provided by operating activities is as follows (in millions): Twelve Months Ended December 31, 2019Net cash provided by operating activities$116.8Changes in assets and liabilities, net of effects of acquisitions and divestitures28.7Gain on sale of property and equipment0.9Non-cash expense from acquisition activities and other items(0.1)Withdrawal costs - multiemployer pension plan(2.2)Stock based compensation(7.2)Operating lease right-of-use assets expense(9.6)Southbridge Landfill non-cash closure charge(0.1)Interest expense, less amortization of debt issuance costs 22.8Benefit for income taxes, net of deferred income taxes(0.6)Adjustments as allowed by the Credit Agreement20.5Consolidated EBITDA$169.9In addition to the 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. We do not believe that these restrictions impact our ability to meet future liquidity needs. As of December 31, 2019, we were in compliance with the covenants contained in the Credit Agreement. An event of 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 default under any provision governing our outstanding debt obligations, our secured lenders could proceed against us and against the 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 tighten during these times as well.Tax-Exempt FinancingsNew York Bonds. In fiscal year 2019, we completed the remarketing of $25.0 million aggregate principal amount of New York Bonds 2014. As of December 31, 2019, we had outstanding $25,000 aggregate principal amount of New York Bonds 2014 and $15,000 aggregate principal amount of New York Bonds 2014R-2 issued by the New York State Environmental Facilities Corporation under the indenture dated December 1, 2014 (collectively, the “New York Bonds”). The New York Bonds 2014 accrue interest at 2.875% per annum through December 2, 2029, at which time they may be converted from a fixed rate to a variable rate. The New York Bonds 2014R-2 accrue interest at 3.125% per annum through May 31, 2026, at which time they may be converted from a fixed rate to a variable rate. The New York Bonds, which are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, require interest payments on June 1 and December 1 of each year and mature on December 1, 2044. We borrowed the proceeds of the New York Bonds to finance or refinance certain capital projects in the state of New York and to pay certain costs of issuance of the New York Bonds.Table of Contents4950 Maine Bonds. In fiscal year 2018, we completed the issuance of $15.0 million aggregate principal amount of FAME Bonds 2015R-2.

The FAME Bonds are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries. We borrowed the proceeds of the offering of the FAME Bonds to finance or refinance the costs of certain of our solid waste landfill facilities and solid waste collection, organics and transfer, recycling and hauling facilities, and to pay certain costs of the issuance of the FAME Bonds.Vermont Bonds. In fiscal year 2018, we completed the remarketing of $16.0 million aggregate principal amount of 4.75% fixed rate senior unsecured Vermont Bonds. As of December 31, 2019, we had outstanding $16.0 million aggregate principal amount of Vermont Bonds. The Vermont Bonds, which are guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 4.625% per annum through April 2, 2028, after which time there is a mandatory tender, and interest is payable semiannually on May 1 and November 1 of each year. The Vermont Bonds mature on April 1, 2036. We borrowed the proceeds of the Vermont Bonds to finance or refinance certain qualifying property, plant and equipment assets purchased in the state of Vermont.New Hampshire Bonds. In fiscal year 2019, we completed the remarketing of $11.0 million aggregate principal amount of senior unsecured New Hampshire Bonds.

The New Hampshire Bonds, which are guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 2.95% per annum through maturity on April 1, 2029 and interest. During the fixed interest rate period, the New Hampshire Bonds are not supported by a letter of credit. Interest is payable on April 1 and October 1 of each year. We borrowed the proceeds of the New Hampshire Bonds to finance or refinance certain qualifying property, plant and equipment assets purchased in the state of New Hampshire.Contractual ObligationsThe following table summarizes our significant contractual obligations and commitments as of December 31, 2019 (in thousands) and the anticipated effect of these obligations on our liquidity in future years:Less thanone year1 - 3 years3 - 5 yearsMore than 5yearsTotalDebt $4,302$8,951$382,837$126,638$522,728Interest obligations (1)19,57238,54524,45651,841134,414Non-cancellable operating leases 7,7159,0962,1665,04824,025Landfill operating lease contracts5,49510,99010,99058,66986,144Final capping, closure and post-closure10,22314,81616,804132,669174,512Total contractual cash obligations (2)$47,307$82,398$437,253$374,865$941,823(1)Based on debt balances as of December 31, 2019.

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 on these implementations, we believe we should be able to sufficiently offset most cost increases resulting from inflation. However, 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 ConditionsOur 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. We are unable to forecast or determine the timing and/or the future impact of a sustained economic slowdown.Critical Accounting Estimates and AssumptionsOur consolidated financial statements have been prepared in accordance with GAAP and necessarily include certain estimates and 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. The following is a list of accounting policies that we believe are the most critical in understanding our consolidated financial position, results of operations and cash flows and that may require management to make subjective or complex judgments about matters that are inherently uncertain. Our significant accounting policies are more fully discussed in Note 3, Summary of Significant Accounting Policies of our consolidated financial statements included in Item 8 of this Annual Report on Form 10-K.Landfill AccountingLandfill Development CostsWe estimate the total cost to develop each of our landfill sites to its remaining permitted and expansion capacity (see landfill development costs discussed within the “Property, Plant and Equipment” accounting policy more fully discussed in Note 3, Summary of Significant Accounting Policies of our consolidated financial statements included in Item 8 of this Annual Report on Form 10-K). The projection of these landfill costs is dependent, in part, on future events. The remaining amortizable basis of each landfill includes costs to develop a site to its remaining permitted and expansion capacity and includes amounts previously expended and capitalized, net of accumulated airspace amortization, and projections of future purchase and development costs including capitalized interest. The interest capitalization rate is based on our weighted average interest rate incurred on borrowings outstanding during the period.Under life-cycle accounting, all costs related to acquisition and construction of landfill sites are capitalized and charged to expense based on tonnage placed into each site. Landfill permitting, acquisition and preparation costs are amortized on the units-of-consumption method as landfill airspace is consumed. In determining the amortization rate for each of our landfills, preparation costs include the total estimated costs to complete construction of the landfills’ permitted and expansion capacity.Final Capping, Closure and Post-Closure CostsThe cost estimates for final capping, closure and post-closure activities at landfills for which we have responsibility are estimated based on our interpretations of current requirements and proposed or anticipated regulatory changes. We also estimate additional costs based on the amount a third-party would charge us to perform such activities even when we expect to perform these activities internally. We estimate the airspace to be consumed related to each final capping event and the timing of construction related to each final capping event and of closure and post-closure activities. Because landfill final capping, closure and post-closure obligations are measured at estimated fair value using present value techniques, changes in the estimated timing of construction of future landfill final capping and closure and post-closure activities would have an effect on these liabilities, related assets and results of operations.Table of Contents5152 Final capping activities include the installation of liners, drainage, compacted soil layers and topsoil over areas of a landfill where total airspace has been consumed and waste is no longer being received. Final capping activities occur throughout the life of the landfill. Our engineering personnel estimate the cost for each final capping event based on the acreage to be capped, along with the final capping materials and activities required. The estimates also consider when these costs would actually be paid and factor in inflation and discount rates. The engineers then quantify the landfill capacity associated with each final capping event and the costs for each event are amortized over that capacity as waste is received at the landfill.Closure and post-closure costs represent future estimated costs related to monitoring and maintenance of a solid waste landfill after a landfill facility ceases to accept waste and closes. We estimate, based on input from our engineers, accountants, lawyers, managers and others, our future cost requirements for closure and post-closure monitoring and maintenance based on our interpretation of the technical standards of the Subtitle D regulations and the air emissions standards under the Clean Air Act of 1970, as amended, as they are being applied on a state-by-state basis. Closure and post-closure accruals for the cost of monitoring and maintenance include site inspection, groundwater monitoring, leachate management, methane gas control and recovery, and operation and maintenance costs to be incurred for a period which is generally for a term of 30 years after final closure of a landfill. In determining estimated future closure and post-closure costs, we consider costs associated with permitted and permittable airspace.See Note 10, Final Capping, Closure and Post-Closure Costs to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for further disclosure.Remaining Permitted AirspaceOur engineers, in consultation with third-party engineering consultants and surveyors, are responsible for determining remaining permitted airspace at our landfills. The remaining permitted airspace is determined by an annual survey, which is then used to compare the existing landfill topography to the expected final landfill topography.Expansion AirspaceWe currently include unpermitted expansion airspace in our estimate of remaining permitted and expansion airspace in certain circumstances. To be considered expansion airspace all of the following criteria must be met: •we control the land on which the expansion is sought;•all technical siting criteria have been met or a variance has been obtained or is reasonably expected to be obtained;•we have not identified any legal or political impediments which we believe will not be resolved in our favor;•we are actively working on obtaining any necessary permits and we expect that all required permits will be received; and•senior management has approved the project based on a review of the engineering design and determination that the financial return profile meets our investment criteria.For unpermitted airspace to be included in our estimate of remaining permitted and expansion airspace, the expansion effort must meet all of the criteria listed above. These criteria are evaluated annually by our engineers, accountants, lawyers, managers and others to identify potential obstacles to obtaining the permits. Once the remaining permitted and expansion airspace is determined in cubic yards, an airspace utilization factor (“AUF”) is established to calculate the remaining permitted and expansion capacity in tons. The AUF is established using a process that considers the measured density obtained from annual surveys. When we include the expansion airspace in our calculation of remaining permitted and expansion airspace, we include the projected costs for development, as well as the projected asset retirement costs related to final capping, closure and post-closure of the expansion airspace in the amortization basis of the landfill.After determining the costs and the remaining permitted and expansion capacity at each of our landfills, we determine the per ton rates that will be expensed as waste is received and deposited at each of our landfills by dividing the costs by the corresponding number of tons. We calculate per ton amortization rates for assets associated with each final capping event, for assets related to closure and post-closure activities, and for all other costs capitalized or to be capitalized in the future for each landfill. These rates per ton are updated annually, or more frequently, as significant facts change.Table of Contents5253 It is possible that actual results, including the amount of costs incurred, the timing of final capping, closure and post-closure activities, our airspace utilization or the success of our expansion efforts could ultimately turn out to be significantly different from our estimates and assumptions. To the extent that such estimates or related assumptions prove to be significantly different than actual results, lower profitability may be experienced due to higher amortization rates, higher final capping, closure or post-closure rates, or higher expenses. Higher profitability may result if the opposite occurs. Most significantly, if it is determined that the expansion capacity should no longer be considered in calculating the recoverability of the landfill asset, we may be required to recognize an asset impairment. If it is determined that the likelihood of receiving an expansion permit has become remote, the capitalized costs related to the expansion effort are expensed immediately.Environmental Remediation LiabilitiesWe have recorded environmental remediation liabilities representing our estimate of the most likely outcome of the matters for which we have determined that a liability is probable. These liabilities include potentially responsible party investigations, settlements, certain legal and consultant fees, as well as costs directly associated with site investigation and clean up, such as materials and incremental internal costs directly related to the remedy. We provide for expenses associated with environmental remediation obligations when such amounts are probable and can be reasonably estimated. We estimate costs required to remediate sites where it is probable that a liability has been incurred based on site-specific facts and circumstances. Estimates of the cost for the likely remedy are developed using third-party environmental engineers or other service providers. Where we believe that both the amount of a particular environmental remediation liability and timing of payments are reliably determinable, we inflate the cost in current dollars until the expected time of payment and discount the cost to present value.See Note 12, Commitments and Contingencies to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for further disclosure.Accounts Receivable, Net of Allowance for Doubtful AccountsAccounts receivable represent receivables from customers for collection, transfer, recycling, disposal and other services. Our accounts receivable are recorded when billed or when related revenue is earned, if earlier, and represent claims against third-parties that will be settled in cash. The carrying value of our accounts receivable, net of allowance for doubtful accounts, represents its estimated net realizable value. Estimates are used in determining our allowance for doubtful accounts based on our historical collection experience, current economic conditions and trends, credit policy and a review of our accounts receivable by aging category. Our reserve is evaluated and revised on a monthly basis. Past-due accounts receivable are written off when deemed to be uncollectible.Goodwill and Other IntangiblesWe annually assess goodwill for impairment at the end of our fiscal year or more frequently if events or circumstances indicate that impairment may exist. We may assess whether a goodwill impairment exists using either a qualitative or a quantitative assessment. If we perform a qualitative assessment, it involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If based on this qualitative assessment we determine it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, we will not perform a quantitative assessment. If the qualitative assessment indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if we elect not to perform a qualitative assessment, we perform a quantitative assessment, or two-step impairment test, to determine whether goodwill impairment exists at the reporting unit.In the first step (defined as “Step 1”) of testing for goodwill impairment, we estimate the fair value of each reporting unit, which we have determined to be our geographic operating segments, our Recycling segment and our Customer Solutions business, which is included in the Other segment, and compare the fair value with the carrying value of the net assets of each reporting unit. If the fair value is less than its carrying value, then we would perform a second step (defined as “Step 2”) and determine the fair value of the goodwill. In Step 2, the fair value of goodwill is determined by deducting the fair value of a reporting unit’s identifiable assets and liabilities from the fair value of the reporting unit as a whole, as if that reporting unit had just been acquired and the purchase price were being initially allocated.To determine the fair value of each of our reporting units as a whole we use discounted cash flow analyses, which require significant assumptions and estimates about the future operations of each reporting unit. Significant judgments inherent in this analysis include the determination of appropriate discount rates, the amount and timing of expected future cash flows and growth rates. The cash flows employed in our discounted cash flow analyses are based on financial forecasts developed internally by management. Our discount rate assumptions are based on an assessment of our risk adjusted discount rate, applicable for each reporting unit. In assessing the reasonableness of our determined fair values of our reporting units, we evaluate our results against our current market capitalizationTable of Contents5354 If the fair value of goodwill is less than its carrying value for a reporting unit, an impairment charge would be recorded to earnings. The loss recognized cannot exceed the carrying amount of goodwill. After a goodwill impairment loss is recognized, the adjusted carrying amount of goodwill becomes its new accounting basis. In addition to an annual goodwill impairment assessment, we would evaluate a reporting unit for impairment if events or circumstances change between annual tests indicating a possible impairment. Examples of such events or circumstances include the following: •a significant adverse change in legal status or in the business climate;•an adverse action or assessment by a regulator;•a more likely than not expectation that a segment or a significant portion thereof will be sold; or•the testing for recoverability of a significant asset group within the segment.We elected to perform a quantitative analysis as part of our annual goodwill impairment test for fiscal year 2019. As of December 31, 2019, the Step 1 testing for goodwill impairment performed for our Eastern, Western, Recycling and Customer Solutions reporting units indicated that the fair value of each reporting unit exceeded its carrying amount, including goodwill. Furthermore, the Step 1 test indicated that in each case the fair value of our Eastern, Western, Recycling and Customer Solutions reporting units exceeded its carrying value by in excess of 34.4%. We incurred no impairment of goodwill as a result of our annual goodwill impairment tests in fiscal years 2019, 2018 and 2017. However, there can be no assurance that goodwill will not be impaired at any time in the future. Effective January 1, 2020, we adopted Accounting Standards Update 2017-04, Intangibles - Goodwill and Other (Topic 350). Under this guidance Step 2 of the testing for goodwill impairment was eliminated and that going forward we would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, noting that the amount is not to exceed the total amount of goodwill allocated to that reporting unit. Intangible assets consist primarily of covenants not-to-compete and customer lists. Intangible assets are recorded at fair value and are amortized based on the economic benefit provided or using the straight-line method over their estimated useful lives. Covenants not-to-compete and customer lists are typically amortized over a term of no more than 10 years.See Note 9, Goodwill and Intangible Assets to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for further disclosure.Recovery of Long-Lived AssetsWe continually assess whether events or changes in circumstances have occurred that may warrant revision of the estimated useful lives of our long-lived assets (other than goodwill) or whether the remaining balances of those assets should be evaluated for possible impairment. Long-lived assets include, for example, capitalized landfill costs, other property and equipment, identifiable intangible assets, and operating lease right-of-use assets. Events or changes in circumstances that may indicate that an asset may be impaired include the following: •a significant decrease in the market price of an asset or asset group;•a significant adverse change in the extent or manner in which an asset or asset group is being used or in its physical condition;•a significant adverse change in legal factors or in the business climate that could affect the value of an asset or asset group, including an adverse action or assessment by a regulator;•an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset;•a current period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group;•a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life; or•an impairment of goodwill at a reporting unit.There are certain indicators listed above that require significant judgment and understanding of the waste industry when applied to landfill development or expansion. For example, a regulator may initially deny a landfill expansion permit application although the expansion permit is ultimately granted. In addition, management may periodically divert waste from one landfill to another to conserve remaining permitted landfill airspace. Therefore, certain events could occur in the ordinary course of business and not necessarily be considered indicators of impairment due to the unique nature of the waste industry.Table of Contents5455 If an impairment indicator occurs, we perform a test of recoverability by comparing the carrying value of the asset or asset group to its undiscounted expected future cash flows. We group our long-lived assets for this purpose at the lowest level for which identifiable cash flows are primarily independent of the cash flows of other assets or asset groups. If the carrying values are in excess of undiscounted expected future cash flows, we measure any impairment by comparing the fair value of the asset or asset group to its carrying value.To determine fair value, we use discounted cash flow analyses and estimates about the future cash flows of the asset or asset group. This analysis includes a determination of an appropriate discount rate, the amount and timing of expected future cash flows and growth rates. The cash flows employed in our discounted cash flow analyses are typically based on financial forecasts developed internally by management. The discount rate used is commensurate with the risks involved. We may also rely on third-party valuations and or information available regarding the market value for similar assets.If the fair value of an asset or asset group is determined to be less than the carrying amount of the asset or asset group, impairment in the amount of the difference is recorded in the period that the impairment occurs. Estimating future cash flows requires significant judgment and projections may vary from the cash flows eventually realized.Investments in Unconsolidated EntitiesInvestments in unconsolidated entities over which we have significant influence over the investees’ operating and financing activities are accounted for under the equity method of accounting, as applicable. Investments in affiliates in which we do not have the ability to exert significant influence over the investees’ operating and financing activities are accounted for under the cost method of accounting.We monitor and assess the carrying value of our investments throughout the year for potential impairment and write them down to their fair value when other-than-temporary declines exist. Fair value is generally based on (i) other third-party investors’ recent transactions in the securities; (ii) other information available regarding the current market for similar assets and/or (iii) a market or income approach, as deemed appropriate.When we assess the carrying value of our investments for potential impairment, determining the fair value of our investments is reliant upon the availability of market information and/or other information provided by third-parties to be able to develop an estimate of fair value. Considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, our estimates are not necessarily indicative of the amounts that we, or other holders of these investments, could realize in a current market exchange. The use of different assumptions and/or estimation methodologies could have a significant effect on the estimated fair values. The current estimates of fair value could differ significantly from the amounts presented.Self-Insurance Liabilities and Related CostsWe are self-insured for vehicles and workers’ compensation with reinsurance coverage limiting our maximum exposure. Our maximum exposure in fiscal year 2019 under the workers’ compensation plan was $1.25 million per individual event. Our maximum exposure in fiscal year 2019 under the automobile plan was $1.2 million per individual event. The liability for unpaid claims and associated expenses, including incurred but not reported losses, is determined by management with the assistance of a third-party actuary and reflected in our consolidated balance sheet as an accrued liability. We use a third-party to track and evaluate actual claims experience for consistency with the data used in the annual actuarial valuation. The actuarially determined liability is calculated based on historical data, which considers both the frequency and settlement amount of claims. Our estimated accruals for these liabilities could be significantly different than our ultimate obligations if variables such as the frequency or severity of future events differ significantly from our assumptions.Income TaxesWe use estimates to determine our provision for income taxes and related assets and liabilities and any valuation allowance recorded against our net deferred tax assets. Valuation allowances have been established for the possibility that tax benefits may not be realized for certain deferred tax assets. Deferred income taxes are recognized based on the expected future tax consequences of differences between the financial statement basis and the tax basis of assets and liabilities, calculated using currently enacted tax rates. We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making this determination, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. In the event we determine that we would be able to realize our deferred income tax assets in the future in excess of their net recorded amount, we will make an adjustment to the valuation allowance which would reduce the provision for income taxes.We account for income tax uncertainties according to guidance on the recognition, de-recognition and measurement of potential tax benefits associated with tax positions. We recognize interest and penalties relating to income tax matters as a component of income tax expense. Table of Contents5556 As previously discussed, the Act, which is also commonly referred to as “U.S. tax reform,” significantly changed United States corporate income tax laws by, among other things, reducing the US corporate income tax rate from 35% to 21% starting in 2018. See Note 16, Income Taxes to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for further disclosure, including the effect of the Act on income taxes.Contingent LiabilitiesWe are subject to various legal proceedings, claims and regulatory matters, the outcomes of which are subject to significant uncertainty. We determine whether to disclose or accrue for loss contingencies based on an assessment of whether the risk of loss is remote, reasonably possible or probable, and whether it can be reasonably estimated. We analyze our litigation and regulatory matters based on available information to assess the potential liabilities. Management’s assessment is developed based on an analysis of possible outcomes under various strategies. We accrue for loss contingencies when such amounts are probable and reasonably estimable. If a contingent liability is only reasonably possible, we will disclose the potential range of the loss, if estimable. We record losses related to contingencies in cost of operations or general and administration expenses, depending on the nature of the underlying transaction leading to the loss contingency. Contingent liabilities accounted for under purchase accounting are recorded at their fair values. These fair values may be different from the values we would have otherwise recorded, had the contingent liability not been assumed as part of an acquisition of a business. See Note 12, Commitments and Contingencies to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for further disclosure.Stock-Based CompensationAll share-based compensation cost is measured at the grant date, based on the estimated fair value of the award, and is recognized as expense-in general and administration expense over the employee’s requisite service period. For purposes of calculating stock-based compensation expense, forfeitures are accounted for as they occur. Our equity awards granted generally consist of stock options, including market-based performance stock options, restricted stock, restricted stock units and performance stock units, including market-based performance stock units.The fair value of each stock option grant is estimated using a Black-Scholes option-pricing model, with the exception of market-based performance stock option grants which are valued using a Monte Carlo option-pricing model. The fair value of restricted stock, restricted stock unit and performance stock unit grants is at a price equal to the fair market value of our Class A common stock at the date of grant. The fair value of market-based performance stock unit grants is valued using a Monte Carlo pricing model. See Note 13, Stockholders' Equity to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for further disclosure.Defined Benefit Pension Plan We currently make contributions to one qualified multiemployer defined benefit pension plan, the Pension Plan. The Pension Plan provides retirement benefits to participants based on their service to contributing employers. We do not administer this plan. The Pension Plan’s benefit formula is based on credited years of service and hours worked as defined in the Pension Plan document. Our pension contributions are made in accordance with funding standards established by the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code, as amended by the Pension Protection Act of 2006. The Pension Plan’s assets have been invested as determined by the Pension Plan's fiduciaries in accordance with the Pension Plan's investment policy. The Pension Plan’s asset allocation is based on the Pension Plan's investment policy and is reviewed as deemed necessary. See Note 15, Employee Benefit Plans to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for further disclosure.New Accounting StandardsFor a description of the new accounting standards that may affect us, see Note 2, Accounting Changes to our consolidated financial statements included in Item 8 of this Annual Report on Form 10-K.ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKIn 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. Table of Contents5657 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 enter into interest rate derivative agreements to manage exposure to fluctuations in interest rates related to variable rate interest payments of our long-term debt. As of both December 31, 2019 and December 31, 2018, our interest rate derivative agreements had a total notional amount of $190.0 million. We receive interest based on the 1-month LIBOR index, restricted by a floor in certain instances, and pay interest at a weighted average rate of approximately 2.54% as of both December 31, 2019 and December 31, 2018. The agreements mature between February 2021 and May 2023. In fiscal year 2019, we entered into interest rate derivative agreements with a total notional amount of $65.0 million that will serve to replace existing interest rate derivative agreements upon their expiration between February 2021 and February 2022. These forward starting interest rate derivative agreements mature between February 2026 and February 2027. We will pay interest at a weighted average rate of approximately 1.79%. 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 (deficit) 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.As of December 31, 2019, we have $145.8 million of fixed rate debt as of December 31, 2019 in addition to the $190.0 million fixed through our interest rate derivative agreements. We had interest rate risk relating to approximately $186.9 million of long-term debt as of December 31, 2019. The weighted average interest rate on the variable rate portion of long-term debt was approximately 3.5% at December 31, 2019. 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 $1.9 million. Commodity Price VolatilityThrough our Recycling operation, we market a variety of materials, including fibers such as old corrugated cardboard and old newsprint, plastics, glass, ferrous and aluminum metals. We may use a number of strategies to mitigate impacts from commodity price fluctuations including: (1) charging collection customers a floating sustainability recycling adjustment fee to offtake recycling commodity risks; (2) in-bound material recovery facilities ("MRF") customers receiving a revenue share or indexed materials purchases in higher commodity price markets, or charging these same customers a processing cost or tipping fee per ton in lower commodity price markets; (3) selling recycling commodities to out-bound MRF customers through floor price or fixed price agreements; or (4) entering into fixed price contracts or hedges that mitigate the variability in cash flows generated from the sales of recycled paper at floating prices. We do not use financial instruments for trading purposes and are not a party to any leveraged derivatives. As of December 31, 2019, we were not party to any commodity hedging agreements.Should commodity prices change by $10 per ton, we estimate that our annual operating income margin would change by approximately $0.3 million annually. Our sensitivity to changes in commodity prices is complex because each customer contract is unique relative to revenue sharing, tipping or processing fees and other arrangements. The above operating income impact may not be indicative of future operating results and actual results may vary materially.Table of Contents5758 ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAReport of Independent Registered Public Accounting FirmTo the Board of Directors of and Stockholders of Casella Waste Systems, Inc. Opinions on the Financial Statements and Internal Control Over Financial ReportingWe have audited the accompanying consolidated balance sheets of Casella Waste Systems, Inc. and subsidiaries (the Company) as of December 31, 2019 and 2018, and the related consolidated statements of operations, comprehensive income (loss), stockholders' equity (deficit) and cash flows for each of the three years in the period ended December 31, 2019, and the related notes and schedules (collectively, the financial statements). We also have audited the Company’s internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.As discussed in Management’s Report on Internal Control Over Financial Reporting, management has excluded: TAM, Inc., TAM Recycling, LLC, TAM Organics, LLC., North Rd. LLC, and 171 Church Street, LLC (collectively TAM); Allied Waste Services of North America, LLC, Browning-Ferris Industries of New York, Inc., Allied Waste Services of Massachusetts LLC, and Menands Environmental Solutions, LLC (collectively Republic); PSI Disposal, Inc. (PSI); Trash Away, LLC (Trash Away); and LT Disposal Inc., River Road Transfer Station Inc., and Center Point Transfer Station, Inc. (collectively, Center Point), because they were acquired by the Company in purchase business combinations during the second, third and fourth quarters of 2019 and have not yet been fully incorporated into the Company’s internal controls over financial reporting. We have also excluded TAM, Republic, PSI, Trash Away and Center Point from our report of internal controls over financial reporting. Collectively, TAM, Republic, PSI, Trash Away and Center Point represent total assets and revenues of approximately 7.1% and 2.0%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2019.Adoption of ASU No. 2016-02 (Topic 842) As discussed in Note 2 to the financial statements, the Company has changed its method of accounting for leases in 2019 due to the adoption of ASU No. 2016-02, Leases (Topic 842), and the related amendments.Basis for OpinionsThe Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's financial statements and an opinion on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.Table of Contents5859 Definition and Limitations of Internal Control Over Financial ReportingA company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.Critical Audit MattersThe critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.Landfill Accounting As described in Note 3 of the consolidated financial statements, the Company accounts for both landfill development assets, including the associated amortization expense, as well as capping, closure and post-closure costs related to its landfills. As of December 31, 2019, the Company’s landfill development assets total $120.2 million, and the associated amortization expense for 2019 was $27.5 million. As of December 31, 2019, the Company estimated its accrued capping, closure and post-closure costs at $71.9 million. The landfill development asset amortization and accrued capping, closure and post-closure costs are based on cash flow analyses, which require significant assumptions and estimates about the future operations and retirement of each landfill. Significant judgments made by management in the cash flow analyses include the determination of the appropriate discount and inflation rates, and the amount and timing of expected future cash flows. Management estimates the timing of expected future cash flows used in the analyses based on various assumptions at each individual landfill including: •Remaining permitted capacity, which is estimated by Company engineers, in consultation with third-party engineers and surveyors, who utilize annual aerial surveys. •The estimation and inclusion of unpermitted expansion airspace.•Compaction factors, or airspace utilization factors (AUF), are estimated using a process that considers the measured density obtained from annual surveys. We identified the Company’s landfill development asset amortization expense and accrued capping, closure and post-closure costs as a critical audit matter because of the significant assumptions and judgments made by management. Auditing management’s assumptions and judgements regarding remaining permitted capacity, unpermitted expansion airspace and compaction factors, accretion and discount rates involved a high degree of auditor judgment and an increased effort, including the use of our valuation specialists. Our audit procedures related to landfill development asset amortization expense and accrued capping, closure and post-closure costs included the following, among others: •We obtained an understanding of the relevant controls related to landfill development asset amortization expense and accrued capping, closure and post-closure costs and tested such controls for design and operating effectiveness, including those over the determination of the appropriate discount and inflation rates, and the amount and timing of expected future cash flows.•We tested internal and external data used in the future cost estimates for both landfill development asset amortization expense and capping, closure and post-closure activities. •We confirmed the landfill topography drawings and results of aerial surveys directly with the third-party engineers. Relevant data outputs from the topography drawings, such as permitted and unpermitted airspace, were agreed to the relevant data inputs in the cash flow analyses. •We verified permitted space to issued permits and reviewed management’s evaluation of unpermitted expansion airspace. Table of Contents5960 •We compared the results of the AUF calculated by aerial surveys to the factors utilized by the Company in the cash flow analyses. •We assessed the appropriateness of the methodology used in developing the inflation rate, as well as verified the completeness and accuracy of the underlying data utilized.•With the assistance of our valuation specialists, we evaluated the Company’s methodology and reasonableness of the credit adjusted risk-free rate. •We assessed the qualifications, reputation and objectivity of management’s third-party engineering specialists. Self-Insurance Liabilities As described in Note 3 of the consolidated financial statements, the Company is self-insured for vehicles and workers’ compensation. The Company’s self-insurance liabilities totaled $16.9 million as of December 31, 2019 and are included in accrued liabilities on the accompanying consolidated balance sheet. The liabilities for unpaid claims and associated expenses, including incurred but not reported losses, are estimated by the Company with the assistance of a third-party actuary. The liability is calculated based on multiple factors and assumptions, which primarily consider the frequency and ultimate settlement amount of claims, supplemented with industry data. We identified the Company’s self-insurance liabilities as a critical audit matter because of the significant judgments made by management as well as the sensitivity of the actuarial assumptions. Auditing management’s judgments regarding the carried loss and allocated loss adjustment expense involved a high degree of auditor judgment and increased effort was required, including the need to involve our external actuarial specialists. Our audit procedures related to the determination of the self-insurance liabilities included the following, among others:•We obtained an understanding of the relevant controls related to the self-insurance liabilities and tested such controls for design and operating effectiveness, including those over the claims processing as well as management’s determination of unpaid claims, associated expenses, and historical claims experience as compared to the data utilized in the actuarial valuation.•We tested the accuracy and completeness of the actual claims paid during the year as well as the loss and exposure data utilized in the actuarial valuation. •With the assistance of our actuarial specialists, we evaluated the reasonableness of the actuarial methodology and assumptions. Our external actuarial specialists also tested the appropriateness of management’s estimates for the carried loss and allocated loss adjustment expense, by comparing management’s estimates to our independently developed estimate.•We assessed the qualifications, reputation and objectivity of management’s third-party actuarial specialists. Valuation of Client List Intangible Assets in Business Combinations As described in Note 5 of the consolidated financial statements, the Company completed the acquisition of nine businesses during the year ended December 31, 2019 for total consideration of $82.2 million. The Company accounted for these transactions under the acquisition method of accounting for business combinations. Accordingly, the purchase price was allocated, on a preliminary basis, to the assets acquired and liabilities assumed based on their respective fair values, including identified intangible assets of $31.2 million and resulting goodwill of $25.7 million. Of the identified intangible assets acquired, the most significant included client list intangible assets of $26.8 million (the “client list intangible assets”). The Company estimated the fair value of the client list intangible assets using the multi-period excess earnings method, which required management to make significant estimates and assumptions related to forecasted revenue and earnings, expected economic life of the asset, contributory asset charges, attrition rates, and the selection of discount rates.We identified the valuation of the client list intangible assets as a critical audit matter because of the significant estimates and assumptions management used in the fair value determination. Auditing management’s forecasts of future cash flows as well as the selection of the discount rates required a high degree of auditor judgment and an increased extent of effort when performing audit procedures, including the use of our valuation specialists.Our audit procedures related to the client list intangible assets included the following, among others:•We obtained an understanding of the relevant controls related to the valuation of the client list intangible assets and tested such controls for design and operating effectiveness, including management’s controls over forecasts of future cash flows and selection of the attrition and discount rates. •We read the purchase and sale agreements to understand and evaluate the terms of the acquisition.•We evaluated the reasonableness of management’s forecasts of future cash flows and attrition rates by comparing the projections to historical results as well as industry benchmarks, and tested the underlying data for accuracy and completeness. Table of Contents6061 •With the assistance of our valuation specialists, we evaluated the reasonableness of the Company’s valuation methodology and significant assumptions by: ◦Testing the source information underlying the determination of the discount rates and verifying the accuracy of the calculations, including the contributory asset charges.◦Developing an analysis for the discount rates and compared that analysis to the discount rates selected by management./s/ RSM US LLP We have served as the Company's auditor since 2010.Boston, MassachusettsFebruary 21, 2020 Table of Contents6162 CASELLA WASTE SYSTEMS, INC.

(“Parent”), its consolidated subsidiaries and any partially owned entities over which it has a controlling financial interest (collectively, “we”, “us” or “our”), is a regional, vertically integrated solid waste services company that provides collection, transfer, disposal, landfill, landfill gas-to-energy, recycling and organics services in the northeastern United States. We market recyclable metals, aluminum, plastics, paper and corrugated cardboard, which have been processed at our recycling facilities, as well as recyclables purchased from third-parties. We manage our solid waste operations on a geographic basis through two regional operating segments, our Eastern and Western regions, each of which provides a full range of solid waste services, and our larger-scale recycling and commodity brokerage operations through our Recycling segment. Organics services, ancillary operations, along with major account and industrial services are included in our Other segment. Effective January 1, 2020, we reorganized our operating segments as follows: we aligned our organics services and our major account and industrial services, with our Recycling segment to form the Resource Solutions segment, thus creating a single resource renewal-focused segment. We also moved our ancillary transportation services, which were previously included in our Other segment, into our Western region. Accordingly, as of January 1, 2020, our operating segments consist of the Eastern and Western regions and Resource Solutions. The accompanying consolidated financial statements, which include the accounts of the Parent, our wholly-owned subsidiaries and any partially owned entities over which we have a controlling financial interest, 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.7071 2.ACCOUNTING CHANGESA table providing a brief description of recent Accounting Standards Updates ("ASUs") to the Accounting Standards Codification (“ASC”) issued by the Financial Accounting Standards Board (“FASB”) that we adopted and deemed to have a material impact on our consolidated financial statements based on current account balances and activity follows:StandardDescriptionEffect on the Financial Statements or OtherSignificant MattersAccounting standards adopted effective January 1, 2019ASU No. 2016-02, as amended through March 2019: Leases (Topic 842)Requires that a lessee recognize at the commencement date: a lease liability, which is the obligation of the lessee to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term.We adopted the guidance using the prospective optional transition method effective January 1, 2019, which allowed us to elect not to restate comparative periods and, if applicable, to recognize the effects of applying this guidance as a cumulative-effect adjustment to retained earnings as of January 1, 2019. We did not recognize a cumulative effect adjustment to retained earnings upon implementation. Upon adopting this guidance, we recognized a right-of-use asset and lease liability for leases classified as operating leases with a term in excess of 12 months in our consolidated balance sheet. We also prospectively reclassified landfill operating lease payments, along with related accumulated depreciation, that were previously capitalized as property, plant and equipment to operating lease right-of-use assets. Accordingly, the related cash outlays, which were historically considered cash flows from investing activities, were prospectively reclassified as cash flows from operating activities in accordance with Topic 842. With the assistance of third-party resources, we designed internal controls over the adoption of this guidance and implemented a third-party enterprise lease management software solution. In conjunction with the implementation, we modified our lease policy and internal business processes to effectively manage and account for leases, and to support recognition and disclosure requirements under the new standard. The adoption of this guidance did not have a material impact on the accounting for our finance leases. This guidance required additional disclosure over leases in order to comply with the new lease standard. See Note 8, Leases for additional disclosure.Table of Contents7172 A table providing a brief description of recent ASUs to the ASC issued by the FASB that are pending adoption and deemed to have a possible material impact on our consolidated financial statements based on current account balances and activity follows: StandardDescriptionEffect on the Financial Statements or OtherSignificant MattersAccounting standards issued pending adoptionASU No. 2019-12: Income Taxes (Topic 740)Reduces the complexity over accounting for income taxes by removing certain exceptions and amending guidance to improve consistent application of accounting over income taxes.We are currently assessing the provisions of this guidance to determine whether or not its adoption will have an impact on our consolidated financial statements and related disclosures. This guidance is effective January 1, 2021 with early adoption permitted. ASU No. 2017-04: Intangibles - Goodwill and Other (Topic 350)Requires that when an entity is performing its annual, or interim, goodwill impairment test, it should compare the fair value of the reporting unit with its carrying amount when calculating its impairment charge, noting that the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, if applicable, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when calculating its impairment charge.As of December 31, 2019, we did not record a goodwill impairment charge related to our annual goodwill impairment test because at that time the fair value of each reporting unit exceeded its respective carrying value. Upon adoption, if the carrying value of any of these reporting units exceeds the fair value when we perform a goodwill impairment test, we would record an impairment charge equal to the amount by which the carrying value exceeds its fair value. We adopted this guidance effective January 1, 2020 and we do not expect our adoption of this guidance to have a material impact on our consolidated financial statements.ASU No. 2016-13: Financial Instrument Credit Losses (Topic 326)Requires that an entity measures all of its expected credit losses for financial assets held based on historical experience, current conditions, and reasonable and supportable forecasts. This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. We adopted this guidance effective January 1, 2020 using the required modified-retrospective approach. We are currently assessing the provisions of this guidance, and we do not expect our adoption of this standard to have a material impact on our consolidated financial statements or to result in a material cumulative effect adjustment to retained earnings as of January 1, 2020.3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIESManagement’s Estimates and AssumptionsPreparation 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 some cases, these estimates are difficult to determine, and we must exercise significant judgment. In preparing our consolidated financial statements, the estimates and assumptions that we consider to be significant and that present the greatest amount of uncertainty relate to our accounting for landfills, environmental remediation liabilities, asset impairments, accounts receivable valuation allowance, self-insurance reserves, deferred taxes and uncertain tax positions, estimates of the fair values of assets acquired and liabilities assumed in any acquisition, contingent liabilities and stock-based compensation. Each of these items is discussed in more detail elsewhere in these notes to consolidated financial statements, as applicable. Actual results may differ materially from the estimates and assumptions that we use in the preparation of our consolidated financial statements.Cash and Cash EquivalentsWe consider all highly liquid investments purchased with original maturities of three months or less to be cash equivalents.Table of Contents7273 Concentrations of Credit RiskFinancial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents, restricted investment securities, accounts receivable and derivative instruments. We maintain cash and cash equivalents and restricted investment securities with banks that at times exceed applicable insurance limits. We reduce our exposure to credit risk by maintaining such deposits with high quality financial institutions. Our concentration of credit risk with respect to accounts receivable is limited because of the large number and diversity of customers we serve, thus reducing the credit risk associated with any one customer group. As of December 31, 2019, no single customer or customer group represented greater than 5% of total accounts receivable. We manage credit risk through credit evaluations, credit limits, and monitoring procedures, but generally do not require collateral to support accounts receivable. We reduce our exposure to credit risk associated with derivative instruments by entering into agreements with high quality financial institutions and by evaluating and regularly monitoring their creditworthiness.Accounts Receivable, Net of Allowance for Doubtful AccountsAccounts receivable represent receivables from customers for collection, transfer, recycling, disposal and other services. Our accounts receivable are recorded when billed or when related revenue is earned, if earlier, and represent claims against third-parties that will be settled in cash. The carrying value of our accounts receivable, net of allowance for doubtful accounts represents its estimated net realizable value. Estimates are used in determining our allowance for doubtful accounts based on our historical collection experience, current economic conditions and trends, credit policy and a review of our accounts receivable by aging category. Our reserve is evaluated and revised on a monthly basis. Past due accounts receivable are written off when deemed to be uncollectible. InventoryInventory includes secondary fibers, recyclables ready for sale, and parts and supplies. Inventory is stated at the lower of cost (first-in, first-out) or market. Property, Plant and EquipmentProperty, plant and equipment is recorded at cost, less accumulated depreciation and amortization. We provide for depreciation and amortization using the straight-line method by charges to operations in amounts that allocate the cost of the assets over their estimated useful lives as follows:Asset ClassificationEstimatedUseful LifeBuildings and improvements10-30 yearsMachinery and equipment5-10 yearsRolling stock5-10 yearsContainers5-12 yearsFurniture and Fixtures3-8 yearsThe cost of maintenance and repairs is charged to operations as incurred.Landfill development costs are included in property, plant and equipment. Landfill development costs include costs to develop each of our landfill sites, including such costs related to landfill liner material and installation, excavation for airspace, landfill leachate collection systems, landfill gas collection systems, environmental monitoring equipment for groundwater and landfill gas, directly related engineering, capitalized interest, on-site road construction, and other capital infrastructure. Additionally, landfill development costs include all land purchases within the landfill footprint and the purchase of any required landfill buffer property. Under life-cycle accounting, these costs are capitalized and charged to expense based on tonnage placed into each site. See the “Landfill Accounting” accounting policy below for additional disclosure over the amortization of landfill development costs and Note 7, Property, Plant and Equipment for disclosure over property, plant and equipment.Landfill AccountingLife Cycle AccountingUnder life-cycle accounting, all costs related to acquisition and construction of landfill sites are capitalized and charged to expense based on tonnage placed into each site. Landfill permitting, acquisition and preparation costs are amortized on the units-of-consumption method as landfill airspace is consumed. In determining the amortization rate for each of our landfills, preparation costs include the total estimated costs to complete construction of the landfills’ permitted and expansion capacity.Table of Contents7374 Landfill Development CostsWe estimate the total cost to develop each of our landfill sites to its remaining permitted and expansion capacity (see landfill development costs discussed within the “Property, Plant and Equipment” accounting policy above). The projection of these landfill costs is dependent, in part, on future events. The remaining amortizable basis of each landfill includes costs to develop a site to its remaining permitted and expansion capacity and includes amounts previously expended and capitalized, net of accumulated airspace amortization, and projections of future purchase and development costs including capitalized interest. The interest capitalization rate is based on our weighted average interest rate incurred on borrowings outstanding during the period. Interest capitalized during the fiscal years ended December 31, 2019 ("fiscal year 2019"), December 31, 2018 ("fiscal year 2018") and December 31, 2017 ("fiscal year 2017") was $263, $140 and $295, respectively.Landfill AirspaceWe apply the following guidelines in determining a landfill’s remaining permitted and expansion airspace:Remaining Permitted Airspace. Our engineers, in consultation with third-party engineering consultants and surveyors, are responsible for determining remaining permitted airspace at our landfills. The remaining permitted airspace is determined by an annual survey, which is then used to compare the existing landfill topography to the expected final landfill topography.Expansion Airspace. We currently include unpermitted expansion airspace in our estimate of remaining permitted and expansion airspace in certain circumstances. To be considered expansion airspace all of the following criteria must be met: •we control the land on which the expansion is sought;•all technical siting criteria have been met or a variance has been obtained or is reasonably expected to be obtained;•we have not identified any legal or political impediments which we believe will not be resolved in our favor;•we are actively working on obtaining any necessary permits and we expect that all required permits will be received; and•senior management has approved the project based on a review of the engineering design and determination that the financial return profile meets our investment criteria.For unpermitted airspace to be included in our estimate of remaining permitted and expansion airspace, the expansion effort must meet all of the criteria listed above. These criteria are evaluated annually by our engineers, accountants, lawyers, managers and others to identify potential obstacles to obtaining the permits. Once the remaining permitted and expansion airspace is determined in cubic yards, an airspace utilization factor (“AUF”) is established to calculate the remaining permitted and expansion capacity in tons. The AUF is established using a process that considers the measured density obtained from annual surveys. When we include the expansion airspace in our calculation of remaining permitted and expansion airspace, we include the projected costs for development, as well as the projected asset retirement costs related to final capping, closure and post-closure of the expansion airspace in the amortization basis of the landfill.After determining the costs and the remaining permitted and expansion capacity at each of our landfills, we determine the per ton rates that will be expensed as waste is received and deposited at each of our landfills by dividing the costs by the corresponding number of tons. We calculate per ton amortization rates for assets associated with each final capping event, for assets related to closure and post-closure activities, and for all other costs capitalized or to be capitalized in the future for each landfill. These rates per ton are updated annually, or more frequently, as significant facts change.It is possible that actual results, including the amount of costs incurred, the timing of final capping, closure and post-closure activities, our airspace utilization or the success of our expansion efforts, could ultimately turn out to be significantly different from our estimates and assumptions. To the extent that such estimates or related assumptions prove to be significantly different than actual results, lower profitability may be experienced due to higher amortization rates, higher final capping, closure or post-closure rates, or higher expenses. Higher profitability may result if the opposite occurs. Most significantly, if it is determined that the expansion capacity should no longer be considered in calculating the recoverability of the landfill asset, we may be required to recognize an asset impairment. If it is determined that the likelihood of receiving an expansion permit has become remote, the capitalized costs related to the expansion effort are expensed immediately.Final Capping, Closure and Post-Closure CostsThe following is a description of our landfill asset retirement activities and related accounting:Final Capping Costs. Final capping activities include the installation of liners, drainage, compacted soil layers and topsoil over areas of a landfill where total airspace has been consumed and waste is no longer being received. Final capping activities occur throughout the life of the landfill. Our engineering personnel estimate the cost for each final capping event based on the acreage to be capped, along with the final capping materials and activities required. The estimates also consider when these costs would actually be paid and factor in inflation and discount rates. The engineers then quantify the landfill capacity associated with each final capping event and the costs for each event are amortized over that capacity as waste is received at the landfill.Table of Contents7475 Closure and Post-Closure Costs. Closure and post-closure costs represent future estimated costs related to monitoring and maintenance of a solid waste landfill after a landfill facility ceases to accept waste and closes. We estimate, based on input from our engineers, accountants, lawyers, managers and others, our future cost requirements for closure and post-closure monitoring and maintenance based on our interpretation of the technical standards of the Subtitle D regulations and the air emissions standards under the Clean Air Act of 1970, as amended, as they are being applied on a state-by-state basis. Closure and post-closure accruals for the cost of monitoring and maintenance include site inspection, groundwater monitoring, leachate management, methane gas control and recovery, and operation and maintenance costs to be incurred for a period which is generally for a term of 30 years after final closure of a landfill. In determining estimated future closure and post-closure costs, we consider costs associated with permitted and permittable airspace.Our estimated future final capping, closure and post-closure costs, based on our interpretation of current requirements and proposed regulatory changes, are intended to approximate fair value. Absent quoted market prices, our cost estimates are based on historical experience, professional engineering judgment and quoted or actual prices paid for similar work. Our estimate of costs to discharge final capping, closure and post-closure asset retirement obligations for landfills are developed in today’s dollars. These costs are then inflated to the period of performance using an estimate of inflation, which is updated annually (1.6% as of December 31, 2019). Final capping, closure and post-closure liabilities are discounted using the credit adjusted risk-free rate in effect at the time the obligation is incurred. The weighted average rate applicable to our asset retirement obligations as of December 31, 2019 is between approximately 8.7% and 10.0%, the range of the credit adjusted risk free rates effective since the adoption of guidance associated with asset retirement obligations in the fiscal year ended April 30, 2004. Accretion expense is necessary to increase the accrued final capping, closure and post-closure liabilities to the future anticipated obligation. To accomplish this, we accrete our final capping, closure and post-closure accrual balances using the same credit-adjusted risk-free rate that was used to calculate the recorded liability. Accretion expense on recorded landfill liabilities is recorded to cost of operations from the time the liability is recognized until the costs are paid. Accretion expense on recorded landfill liabilities amounted to $6,227, $5,556 and $4,401 in fiscal years 2019, 2018 and 2017, respectively.We provide for the accrual and amortization of estimated future obligations for closure and post-closure based on tonnage placed into each site. With regards to final capping, the liability is recognized, and the costs are amortized based on the airspace related to the specific final capping event. See Note 10, Final Capping, Closure and Post-Closure Costs for disclosure over asset retirement obligations related to final capping, closure and post-closure costs.We operate in states which require a certain portion of landfill final capping, closure and post-closure obligations to be secured by financial assurance, which may take the form of surety bonds, letters of credit and restricted investment securities. Surety bonds securing closure and post-closure obligations at December 31, 2019 and December 31, 2018 totaled $220,633 and $201,177, respectively. Letters of credit securing closure and post-closure obligations as of December 31, 2019 and December 31, 2018 totaled $0 and $0, respectively. See Note 6, Restricted Assets for disclosure over restricted investment securities securing closure and post-closure obligations.Lease AccountingWe lease vehicles, equipment, property and other non-core equipment in the ordinary course of our business. Leases are classified as either operating leases or finance leases, as appropriate. Our leases have varying terms and may include renewal or purchase options, escalation clauses, restrictions, lease concessions, capital project funding, penalties or other obligations that we considered historically in determining minimum rental payments. We recognize lease expense for operating leases on a straight-line basis over the lease term. We recognize depreciation expense for finance leases over either the useful life of the asset or the lease term based on the terms of the lease agreement.We are also party to three landfill operation and management agreements. These agreements are long-term landfill operating contracts with government bodies whereby we receive tipping revenue, pay normal operating expenses and assume future final capping, closure and post-closure obligations. The government body retains ownership of the landfill. There is no bargain purchase option and title to the property does not pass to us at the end of the lease term. We allocate the consideration paid to the landfill airspace rights and underlying land lease based on the relative fair values. In addition to up-front or one-time payments, the landfill operating agreements may require us to make future minimum rental payments, including success/expansion fees, other direct costs and final capping, closure and post-closure costs. The value of all future minimum rental payments is amortized and charged to cost of operations over the life of the contract. We amortize the consideration allocated to airspace rights as airspace is utilized on a units-of-consumption basis and such amortization is charged to cost of operations as airspace is consumed (e.g., as tons are placed into the landfill). The underlying value of any land lease is amortized to cost of operations on a straight-line basis over the estimated life of the operating agreement. Table of Contents7576 As a part of the implementation of Topic 842, we elected to adopt the practical expedient package and to not elect the hindsight practical expedient in determining lease term. The practical expedient package allowed us to: 1) not reassess lease classification for existing leases; 2) not reassess whether a contract contains a lease for existing contracts; and 3) not reassess initial direct costs for existing leases. Accordingly, we retained the operating lease and finance lease classifications in all periods presented and did not alter Topic 840 accounting over operating leases in place at transition allowing us to use historical minimum rental payments when determining the right-of-use asset and lease liability for existing operating leases. Upon adopting this guidance, we recognized a right-of-use asset and a lease liability for core leases classified as operating leases with a term in excess of 12 months in our consolidated balance sheet. For other non-core operating leases, which is comprised of small-dollar-value items such as office equipment, we continued to expense these costs in the period incurred rather than capitalizing such expenditures on our consolidated balance sheet. Accounting for finance leases was not impacted by the adoption of this guidance.Under Topic 842, we identify lease and nonlease components in a contract to which consideration in the contract will be allocated. We may elect by class of underlying asset to choose not to separate nonlease components from lease components and instead account for each separate lease component and the nonlease components in a contract as part of the single lease component. We have elected to not separate lease components from nonlease components for property leases and are, therefore, not allocating consideration between lease and nonlease components for this asset class. Lease payments include: fixed payments, including in-substance fixed payments, less any lease incentives paid or payable to the lessee; variable lease payments that depend on an index or a rate; exercise price of a purchase option reasonably certain to be exercised; penalties for terminating a lease; and amounts where it is probable that we will owe under a residual value guarantee. Refundable deposits are not considered to be a fixed payment. Variable lease costs that are not based on an index or a rate are recorded to expense in the period incurred. Lease term is determined at lease commencement, and includes any noncancellable period for which we have the right to use the underlying asset together with any periods covered by an option to extend or terminate the lease if we are reasonably certain to exercise the option to extend or not to exercise the option to terminate. The initial determination of a lease liability is calculated as the net present value of the lease payments not yet paid. The discount rate used to determine present value is the rate implicit in the lease, if present, or, if not present, our incremental borrowing rate, which is a rate that reflects interest that we would have to pay to borrow funds on a collateralized basis over a similar term to the lease and in a similar economic environment. For shorter term leases, such as vehicle and equipment leases, we calculate our incremental borrowing rate using the interest rate from our existing secured line of credit, adjusted based on term. For longer term leases, such as our landfill operating leases, we calculate our incremental borrowing rate based on an industry yield curve with a similar credit rating, adjusted by a company specific spread as determined by a third-party.See Note 8, Leases for further disclosure over lease costs and other lease information.Goodwill and Intangible AssetsGoodwill. Goodwill is the excess of our purchase cost over the fair value of the net assets of acquired businesses. We do not amortize goodwill, but as discussed in the “Asset Impairments” accounting policy below, we assess our goodwill for impairment at least annually. See Note 9, Goodwill and Intangible Assets for disclosure over goodwill.Intangible Assets. Intangible assets consist primarily of covenants not-to-compete and customer lists. Intangible assets are recorded at fair value and are amortized based on the economic benefit provided or using the straight-line method over their estimated useful lives. Covenants not-to-compete and customer lists are typically amortized over a term of no more than 10 years. See Note 9, Goodwill and Intangible Assets for disclosure over intangible assets.Investments in Unconsolidated EntitiesInvestments in unconsolidated entities over which we have significant influence over the investees’ operating and financing activities are accounted for under the equity method of accounting. Investments in affiliates in which we do not have the ability to exert significant influence over the investees’ operating and financing activities are accounted for under the cost method of accounting. As of December 31, 2019 and December 31, 2018, we had no investments accounted for under the equity method of accounting. As of both December 31, 2019 and December 31, 2018, we had cost method investments totaling $11,264.We monitor and assess the carrying value of our investments throughout the year for potential impairment and write them down to their fair value when other-than-temporary declines exist. Fair value is generally based on (i) other third-party investors’ recent transactions in the securities; (ii) other information available regarding the current market for similar assets and/or (iii) a market or income approach, as deemed appropriate.Table of Contents7677 When we assess the carrying value of our investments for potential impairment, determining the fair value of our investments is reliant upon the availability of market information and/or other information provided by third-parties to be able to develop an estimate of fair value. Considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, our estimates are not necessarily indicative of the amounts that we, or other holders of these investments, could realize in a current market exchange. The use of different assumptions and/or estimation methodologies could have a significant effect on the estimated fair values. The estimates of fair value could differ significantly from the amounts presented. See “Asset Impairments” accounting policy below.Fair Value of Financial InstrumentsOur financial instruments may 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, restricted cash reserved to finance certain capital projects, interest rate derivatives, trade payables and long-term debt. Accounting standards include disclosure requirements around fair values used for certain financial instruments and establish a fair value hierarchy. The three-tier hierarchy prioritizes valuation inputs into three levels based on the extent to which inputs used in measuring fair value are observable in the market. Each fair value measurement is reported in one of three levels: 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. See Note 11, Debt and Note 14, Fair Value of Financial Instruments for fair value disclosure over long-term debt and financial instruments, respectively. See the “Derivatives and Hedging” accounting policy below for the fair value disclosure over interest rate derivatives.Business CombinationsWe acquire businesses in the waste industry, including non-hazardous waste collection, transfer station, recycling and disposal operations, as part of our growth strategy. Businesses are included in the consolidated financial statements from the date of acquisition.We recognize, separately from goodwill, the identifiable assets acquired and liabilities assumed at their estimated acquisition-date fair values. We measure and recognize goodwill as of the acquisition date as the excess of: (a) the aggregate of the fair value of consideration transferred, the fair value of any noncontrolling interest in the acquiree (if any) and the acquisition date fair value of our previously held equity interest in the acquiree (if any), over (b) the fair value of net assets acquired and liabilities assumed. If information about facts and circumstances existing as of the acquisition date is incomplete by the end of the reporting period in which a business combination occurs, we will report provisional amounts for the items for which the accounting is incomplete. The measurement period ends once we receive the information we were seeking; however, this period will not extend beyond one year from the acquisition date. Any material adjustments recognized during the measurement period will be recognized retrospectively in the consolidated financial statements of the current period. All acquisition related transaction and restructuring costs are to be expensed as incurred. See Note 5, Business Combinations for disclosure over business acquisitions.Environmental Remediation LiabilitiesWe have recorded environmental remediation liabilities representing our estimate of the most likely outcome of the matters for which we have determined that a liability is probable. These liabilities include potentially responsible party investigations, settlements, certain legal and consultant fees, as well as costs directly associated with site investigation and clean up, such as materials and incremental internal costs directly related to the remedy. We provide for expenses associated with environmental remediation obligations when such amounts are probable and can be reasonably estimated. We estimate costs required to remediate sites where it is probable that a liability has been incurred based on site-specific facts and circumstances. Estimates of the cost for the likely remedy are developed using third-party environmental engineers or other service providers. Where we believe that both the amount of a particular environmental remediation liability and timing of payments are reliably determinable, we inflate the cost in current dollars until the expected time of payment and discount the cost to present value.See Note 12, Commitments and Contingencies for disclosure over environmental remediation liabilities.Table of Contents7778 Self-Insurance Liabilities and Related CostsWe are self-insured for vehicles and workers’ compensation with reinsurance coverage limiting our maximum exposure. Our maximum exposure in fiscal year 2019 under the workers’ compensation plan was $1,250 per individual event. Our maximum exposure in fiscal year 2019 under the automobile plan was $1,200 per individual event. The liability for unpaid claims and associated expenses, including incurred but not reported losses, is determined by management with the assistance of a third-party actuary and reflected in our consolidated balance sheet as an accrued liability. We use a third-party to track and evaluate actual claims experience for consistency with the data used in the annual actuarial valuation. The actuarial-determined liability is calculated based on historical data, which considers both the frequency and settlement amount of claims. Our self-insurance reserves totaled $16,853 and $15,040 as of December 31, 2019 and December 31, 2018, respectively. Our estimated accruals for these liabilities could be significantly different than our ultimate obligations if variables such as the frequency or severity of future events differ significantly from our assumptions.Income TaxesWe use estimates to determine our provision for income taxes and related assets and liabilities and any valuation allowance recorded against our net deferred tax assets. Valuation allowances have been established for the possibility that tax benefits may not be realized for certain deferred tax assets. Deferred income taxes are recognized based on the expected future tax consequences of differences between the financial statement basis and the tax basis of assets and liabilities, calculated using currently enacted tax rates. We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making this determination, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. In the event we determine that we would be able to realize our deferred income tax assets in the future in excess of their net recorded amount, we will make an adjustment to the valuation allowance which would reduce the provision for income taxes.We account for income tax uncertainties according to guidance on the recognition, de-recognition and measurement of potential tax benefits associated with tax positions. We recognize interest and penalties relating to income tax matters as a component of income tax expense. On December 22, 2017, the Tax Cuts and Jobs Act was enacted. The Tax Cuts and Jobs Act, which is also commonly referred to as “U.S. tax reform,” significantly changes United States corporate income tax laws by, among other things, reducing the US corporate income tax rate from 35% to 21% starting in 2018. See Note 16, Income Taxes for disclosure related to income taxes, including the effect of the Act on income taxes.Derivatives and HedgingWe account for derivatives and hedging activities in accordance with derivatives and hedging accounting guidance that establishes accounting and reporting standards requiring that every derivative instrument (including certain derivative instruments embedded in other contracts) be recorded in the balance sheet as either an asset or liability measured at its fair value. The guidance requires that changes in the derivative’s fair value be recognized currently in earnings unless specific hedge accounting criteria are met. Our objective for utilizing derivative instruments is to reduce our exposure to fluctuations in cash flows due to changes in the commodity prices of recycled paper and adverse movements in interest rates. Our strategy to hedge against fluctuations in the commodity prices of recycled paper is to enter into hedges to mitigate the variability in cash flows generated from the sales of recycled paper at floating prices, resulting in a fixed price being received from these sales. We evaluate the hedges and ensure that these instruments qualify for hedge accounting pursuant to derivative and hedging guidance. Designated as highly effective cash flow hedges, both the effective and ineffective portion of the change in the fair value of these derivatives is recorded in our stockholders’ equity (deficit) as a component of accumulated other comprehensive loss until the hedged item is settled and recognized as part of commodity revenue. If the price per short ton of the underlying commodity, as reported on the Official Board Market, is less than the contract price per short ton, we receive the difference between the average price and the contract price (multiplied by the notional tons) from the respective counter-party. If the price per short ton of the underlying commodity exceeds the contract price per short ton, we pay the calculated difference to the counter-party. The fair value of commodity hedges is obtained or derived from our counter-parties using valuation models that take into consideration market price assumptions for commodities based on underlying active markets. We were not party to any commodity hedge contracts as of December 31, 2019.Our strategy to hedge against fluctuations in variable interest rates involves entering into interest rate derivative agreements to hedge against adverse movements in interest rates. For interest rate derivatives deemed to be highly effective cash flow hedges, both the effective and ineffective portion of the change in fair value of these derivatives is recorded in our stockholders’ equity (deficit) as a component of accumulated other comprehensive loss and reclassified into earnings through interest expense in the same period or periods during which the hedged transaction affects earnings.Table of Contents7879 See Note 14, Fair Value of Financial Instruments for fair value disclosure over derivative instruments and Note 11, Debt for further disclosure over interest rate derivatives. Contingent LiabilitiesWe are subject to various legal proceedings, claims and regulatory matters, the outcomes of which are subject to significant uncertainty. We determine whether to disclose or accrue for loss contingencies based on an assessment of whether the risk of loss is remote, reasonably possible or probable, and whether it can be reasonably estimated. We analyze our litigation and regulatory matters based on available information to assess the potential liabilities. Management’s assessment is developed based on an analysis of possible outcomes under various strategies. We accrue for loss contingencies when such amounts are probable and reasonably estimable. If a contingent liability is only reasonably possible, we will disclose the potential range of the loss, if estimable. We record losses related to contingencies in cost of operations or general and administration expenses, depending on the nature of the underlying transaction leading to the loss contingency. See Note 12, Commitments and Contingencies for disclosure over loss contingencies, as applicable. Contingent liabilities accounted for under purchase accounting are recorded at their fair values. These fair values may be different from the values we would have otherwise recorded, had the contingent liability not been assumed as part of an acquisition of a business. Revenue RecognitionWe adopted ASU 2014-09, as amended, Revenue from Contracts with Customers (Topic 606) effective January 1, 2018. We adopted this guidance using the modified retrospective approach, noting that no cumulative effect adjustment to the beginning balance of Accumulated Deficit was needed. The comparative periods have not been restated and continue to be reported under Revenue Recognition (Topic 605). We applied this guidance to contracts that were not substantially completed contracts at the date of adoption. Additionally, contract modifications that occurred before the adoption date were not separately evaluated, rather the guidance was applied to the current version of the contract only. We disaggregate our revenues by applicable service line: collection, landfill, transfer, customer solutions, recycling, organics, transportation and landfill gas-to-energy. Under the new revenue recognition guidance, revenues are measured based on the consideration specified in a contract with a customer. The circumstances that impact the timing and amount of revenue recognized for each applicable service line may vary based on the nature of the service performed. We generally recognize revenues for services over time as we satisfy the performance obligation by transferring control over the service to the customer as the service is performed and the benefit is received and consumed by the customer. Services are typically delivered in a series as a single bundled performance obligation over either a designated period of time or for specified number of services. Services may also be delivered as a single bundled service, on a period-to-period basis, or in a spot transaction. Consideration may be variable on a per ton basis and/or fixed. Fixed consideration is allocated to each distinct service and variable consideration is allocated to the increment of time that the service is performed, and we have the contractual right to the fee. Fees are typically billed weekly, monthly, quarterly or in advance. Generally, the amount of consideration that we have the right to receive that is invoiced to the customer directly corresponds to the value of our performance completed to date. We elected the optional exemption, to not disclose the amount of variable consideration included in the transaction price that is allocated to outstanding performance obligations when the variable consideration is allocated entirely to unsatisfied performance obligations or to a wholly unsatisfied promise to transfer a distinct good or service that forms part of a single performance obligation. Revenues that are not satisfied over time are recognized at a point-in-time. This typically includes the sale of recycled or organic materials, as well as renewable energy credits ("RECs"). Revenues from the sale of organic or recycled materials are recognized at a point-in-time as control of the materials transfers to the customer upon shipment or pick-up by the customer. Revenues from the sale of RECs are recognized at a point-in-time as the trade is executed and control transfers to the customer. Payments to customers that are not in exchange for a distinct good or service are recorded as a reduction of revenues. Rebates to certain customers associated with payments for recycled or organic materials that are received and subsequently processed and sold to other third-parties amounted to $4,428 and $6,279 in fiscal year 2019 and 2018, respectively. Rebates are generally recorded as a reduction of revenues upon the sale of such materials, or upon receipt of the recycled materials at our facilities. These payments were previously recorded as a cost of operations. We did not record any revenues in fiscal year 2019 or fiscal year 2018 from performance obligations satisfied in previous periods. Contract receivables, which are included in Accounts receivable, net are recorded when billed or when related revenue is earned, if earlier, and represent claims against third-parties that will be settled in cash. Accounts receivable, net includes gross receivables from contracts of $80,191 and $73,500 as of December 31, 2019 and December 31, 2018, respectively. Certain customers are billed in advance and, accordingly, recognition of the related revenues is deferred as a contract liability until the services are provided and control transferred to the customer. Contract liabilities of $2,299 and $3,074 as of December 31, 2019 and December 31, 2018, respectively, are presented separately on the face of the Consolidated Balance Sheets. Due to the short-term nature of advanced billings, substantially all of the deferred revenue recognized as a contract liability as of December 31, 2018 and December 31, 2017 was recognized as revenue during fiscal year 2019 and 2018 when the services were performed. Table of Contents7980 See Note 4, Revenue Recognition for disclosure over the new guidance.Asset ImpairmentsRecovery of Long-Lived Assets. We continually assess whether events or changes in circumstances have occurred that may warrant revision of the estimated useful lives of our long-lived assets (other than goodwill) or whether the remaining balances of those assets should be evaluated for possible impairment. Long-lived assets include, for example, capitalized landfill costs, other property, plant and equipment, identifiable intangible assets, and operating lease right-of-use assets. Events or changes in circumstances that may indicate that an asset may be impaired include the following: •a significant decrease in the market price of an asset or asset group;•a significant adverse change in the extent or manner in which an asset or asset group is being used or in its physical condition;•a significant adverse change in legal factors or in the business climate that could affect the value of an asset or asset group, including an adverse action or assessment by a regulator;•an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset;•a current period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group; •a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life; or•an impairment of goodwill at a reporting unit.There are certain indicators listed above that require significant judgment and understanding of the waste industry when applied to landfill development or expansion. For example, a regulator may initially deny a landfill expansion permit application although the expansion permit is ultimately granted. In addition, management may periodically divert waste from one landfill to another to conserve remaining permitted landfill airspace. Therefore, certain events could occur in the ordinary course of business and not necessarily be considered indicators of impairment due to the unique nature of the waste industry.If an impairment indicator occurs, we perform a test of recoverability by comparing the carrying value of the asset or asset group to its undiscounted expected future cash flows. We group our long-lived assets for this purpose at the lowest level for which identifiable cash flows are primarily independent of the cash flows of other assets or asset groups. If the carrying values are in excess of undiscounted expected future cash flows, we measure any impairment by comparing the fair value of the asset or asset group to its carrying value.To determine fair value, we use discounted cash flow analyses and estimates about the future cash flows of the asset or asset group. This analysis includes a determination of an appropriate discount rate, the amount and timing of expected future cash flows and growth rates. The cash flows employed in our discounted cash flow analyses are typically based on financial forecasts developed internally by management. The discount rate used is commensurate with the risks involved. We may also rely on third-party valuations and or information available regarding the market value for similar assets.If the fair value of an asset or asset group is determined to be less than the carrying amount of the asset or asset group, impairment in the amount of the difference is recorded in the period that the impairment occurs. Estimating future cash flows requires significant judgment and projections may vary from the cash flows eventually realized.See Note 17, Other Items and Charges for disclosure related to long-lived asset impairments recognized during the reporting periods.Goodwill. We annually assess goodwill for impairment at the end of our fiscal year or more frequently if events or circumstances indicate that impairment may exist. We may assess whether a goodwill impairment exists using either a qualitative or a quantitative assessment. If we perform a qualitative assessment, it involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If based on this qualitative assessment we determine it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, we will not perform a quantitative assessment. If the qualitative assessment indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if we elect not to perform a qualitative assessment, we perform a quantitative assessment, or two-step impairment test, to determine whether goodwill impairment exists at the reporting unit.Table of Contents8081 In the first step (defined as “Step 1”) of testing for goodwill impairment, we estimate the fair value of each reporting unit, which we have determined to be our geographic operating segments, our Recycling segment and our Customer Solutions business, which is included in the Other segment, and compare the fair value with the carrying value of the net assets of each reporting unit. If the fair value is less than its carrying value, then we would perform a second step (defined as “Step 2”) and determine the fair value of the goodwill. In Step 2, the fair value of goodwill is determined by deducting the fair value of a reporting unit’s identifiable assets and liabilities from the fair value of the reporting unit as a whole, as if that reporting unit had just been acquired and the purchase price were being initially allocated.To determine the fair value of each of our reporting units as a whole we use discounted cash flow analyses, which require significant assumptions and estimates about the future operations of each reporting unit. Significant judgments inherent in this analysis include the determination of appropriate discount rates, the amount and timing of expected future cash flows and growth rates. The cash flows employed in our discounted cash flow analyses are based on financial forecasts developed internally by management. Our discount rate assumptions are based on an assessment of our risk adjusted discount rate, applicable for each reporting unit. In assessing the reasonableness of our determined fair values of our reporting units, we evaluate our results against our current market capitalization.If the fair value of goodwill is less than its carrying value for a reporting unit, an impairment charge would be recorded to earnings. The loss recognized cannot exceed the carrying amount of goodwill. After a goodwill impairment loss is recognized, the adjusted carrying amount of goodwill becomes its new accounting basis.In addition to an annual goodwill impairment assessment, we would evaluate a reporting unit for impairment if events or circumstances change between annual tests indicating a possible impairment. Examples of such events or circumstances include the following: •a significant adverse change in legal status or in the business climate;•an adverse action or assessment by a regulator;•a more likely than not expectation that a segment or a significant portion thereof will be sold; or •the testing for recoverability of a significant asset group within the segment.We elected to perform a quantitative analysis as part of our annual goodwill impairment test for fiscal year 2019. As of December 31, 2019, the Step 1 testing for goodwill impairment performed for our Eastern, Western, Recycling and Customer Solutions reporting units indicated that the fair value of each reporting unit exceeded its carrying amount, including goodwill. Furthermore, the Step 1 test indicated that in each case the fair value of our Eastern, Western, Recycling and Customer Solutions reporting units exceeded its carrying value by in excess of 34.4%. We incurred no impairment of goodwill as a result of our annual goodwill impairment tests in each of fiscal years 2019, 2018 and 2017. However, there can be no assurance that goodwill will not be impaired at any time in the future. Effective January 1, 2020, we adopted ASU 2017-04, Intangibles - Goodwill and Other (Topic 350). Under this guidance Step 2 of the testing for goodwill impairment was eliminated and that going forward we would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, noting that the amount is not to exceed the total amount of goodwill allocated to that reporting unit. See Note 2, Accounting Changes for disclosure related to the adoption of this guidance.Cost Method Investments. We monitor and assess the carrying value of our cost method investments throughout the year for potential impairment and write them down to their fair value when other-than-temporary declines exist. We incurred no impairment of cost method investments in fiscal year 2019 or fiscal year 2017. As of December 31, 2018, we owned 6.8% of the outstanding common stock of Recycle Rewards, Inc. (“Recycle Rewards”), a company that markets an incentive-based recycling service. In fiscal year 2018, it was determined based on the operating performance of Recycle Rewards that our cost method investment in Recycle Rewards was potentially impaired. As a result, we performed a valuation analysis in fiscal year 2018, which used an income approach based on discounted cash flows to determine an equity value for Recycle Rewards in order to properly value our cost method investment in Recycle Rewards. Based on this analysis, it was determined that the fair value of our cost method investment in Recycle Rewards was less than the carrying amount and, therefore, we recorded an other-than-temporary investment impairment charge for the full cost method investment amount of $1,069 in fiscal year 2018. In October 2019, Recycle Rewards sold all or substantially all of its assets comprising the business to RTS RecycleBank, LLC, a subsidiary of Recycle Track Systems, pursuant to an asset purchase agreement. Based on our junior ownership position, we did not receive any proceeds from this disposition.There can be no assurance that our cost method investments will not be impaired at any time in the future.Table of Contents8182 Defined Benefit Pension Plan We make contributions to one qualified multiemployer defined benefit pension plan, the New England Teamsters and Trucking Industry Pension Fund ("Pension Plan"). The Pension Plan provides retirement benefits to participants based on their service to contributing employers. We do not administer this plan. The Pension Plan’s benefit formula is based on credited years of service and hours worked as defined in the Pension Plan document. Our pension contributions are made in accordance with funding standards established by the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code, as amended by the Pension Protection Act of 2006. The Pension Plan’s assets have been invested as determined by the Pension Plan's fiduciaries in accordance with the Pension Plan's investment policy. The Pension Plan’s asset allocation is based on the Pension Plan's investment policy and is reviewed as deemed necessary. See Note 15, Employee Benefit Plans for disclosure over the Pension Plan.Stock-Based CompensationAll share-based compensation cost is measured at the grant date based on the estimated fair value of the award and is recognized as expense-in general and administration expense over the employee’s requisite service period. For purposes of calculating stock-based compensation expense, forfeitures are accounted for as they occur. Our equity awards granted generally consist of stock options, including market-based performance stock options, restricted stock, restricted stock units and performance stock units, including market-based performance stock units.The fair value of each stock option grant is estimated using a Black-Scholes option-pricing model, with the exception of market-based performance stock option grants which are valued using a Monte Carlo option-pricing model. The fair value of restricted stock, restricted stock unit and performance stock unit grants is at a price equal to the fair market value of our Class A common stock at the date of grant. The fair value of market-based performance stock unit grants is valued using a Monte Carlo pricing model. See Note 13, Stockholders' Equity for disclosure over stock-based compensation.Earnings per ShareBasic earnings per share is computed by dividing the net income (loss) 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. Dilutive shares include the assumed exercise of employee stock options, including market-based performance stock options based on the expected achievement of performance targets, 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. See Note 18, Earnings Per Share for disclosure over the calculation of earnings per share.Subsequent EventsExcept as disclosed, no material subsequent events have occurred since December 31, 2019 through the date of this filing that would require recognition or disclosure in our consolidated financial statements.4.REVENUE RECOGNITIONWe disaggregate our revenues by applicable service line as follows: collection, landfill, transfer, customer solutions, recycling, organics, transportation and landfill gas-to-energy. CollectionCollection revenues are principally generated by providing waste collection and disposal services to our customers. Services may be provided as needed or as scheduled. We derive a substantial portion of our collection revenues from commercial and industrial services, which typically have a standard contract duration of three years, along with municipal services that are generally performed pursuant to contracts with municipalities with varying terms. The majority of our residential collection services are performed on a subscription basis with individual households. LandfillLandfill disposal services primarily consist of receiving some form of acceptable solid waste materials at one of our landfills and appropriately disposing of it. Landfill customers are typically charged a tipping fee on a per ton basis for disposing of their solid waste at our disposal facilities. In general, these fees are variable in nature.Table of Contents8283 Transfer StationTransfer station disposal services primarily consist of receiving some form of acceptable solid waste materials at one of our transfer stations and appropriately disposing of it by transporting it to an appropriate disposal site. Transfer station customers are charged a tipping fee on a per ton basis for disposing of their solid waste at our transfer stations. In general, these fees are variable in nature.TransportationTransportation services consist of the transportation of large volumes of waste or recycled materials from a customer designated location to another location or disposal facility. Transportation customers are charged a fee on a per ton basis for transporting and/or disposal of the materials. In general, these fees are variable in nature.RecyclingRecycling services primarily consist of the collection and/or receipt of recycled materials at one of our materials recovery facilities; the processing or sorting of the recycled materials; and the disposal or sale of the recycled materials. Revenues from recycling services consist of revenues derived from municipalities and customers in the form of processing fees, tipping fees and commodity sales. 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.Customer SolutionsCustomer solutions services consist of commercial and industrial offerings. Commercial services consist of traditional collection, disposal and recycling services provided to large account multi-site customers. Industrial services consist of overall resource management services provided to large and complex organizations, such as universities, hospitals, manufacturers and municipalities, delivering a wide range of environmental services and zero waste solutions.Organics Organics services primarily consist of the collection and/or receipt of organic materials at one of our processing or disposal facilities; the processing of the organic materials; and the disposal or sale of the organic materials. Landfill Gas-to-EnergyLandfill gas-to-energy services primarily consist of the generation and sale of electricity from landfill gas-to-energy facilities located at certain of our landfills; the reservation of electric generating capacity to be used by a customer on demand; and the sale of RECs.

BUSINESS COMBINATIONSIn fiscal year 2019, we acquired nine businesses: three tuck-in solid waste collection businesses in our Eastern region; and four tuck-in solid waste collection businesses, a business comprised of solid waste collection, transfer and recycling operations, and a business comprised of solid waste hauling and transfer assets in our Western region. In fiscal year 2018 we acquired nine businesses: six solid waste collection businesses and one transfer business in our Western region; and two businesses comprised of solid waste collection and transfer operations in our Eastern region. In fiscal year 2017, we acquired four businesses: one solid waste collection business in our Eastern region; and three solid waste collection businesses in our Western region. The operating results of these businesses are included in the accompanying audited consolidated statements of operations from each date of acquisition, and the purchase price has been allocated to the net assets acquired based on fair values at each date of acquisition, with the residual amounts recorded as goodwill. Acquired intangible assets other than goodwill that are subject to amortization include client lists and non-compete covenants. These are amortized over a five to ten-year period from the date of acquisition. All amounts recorded to goodwill in fiscal years 2019 and 2018, except goodwill related to certain acquisitions are expected to be deductible for tax purposes.

FINAL CAPPING, CLOSURE AND POST-CLOSURE COSTSAccrued 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 as further described in Note 3, Summary of Significant Accounting Policies. 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.

The net proceeds from this transaction were used to repay in full the amounts outstanding of the $350,000 aggregate principal amount term loan B facility ("Term Loan B Facility") and the $160,000 revolving line of credit facility plus accrued and unpaid interest thereon and to pay related transaction expenses. We have the right to request, at our discretion, an increase in the amount of loans under the Credit Facility by an aggregate amount $125,000, subject to the terms and conditions set forth in the Credit Agreement. The Credit Facility has a 5-year term and bears interest at a rate of LIBOR plus 1.75%, which can be reduced to a rate of LIBOR plus 1.25% upon us reaching a consolidated net leverage ratio of less than 2.25x. 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 December 31, 2019, further advances were available under the Credit Facility in the amount of $148,575. The available amount is net of outstanding irrevocable letters of credit totaling $24,525, at which date 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 December 31, 2019, 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. An event of 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 default under any provision governing our outstanding debt obligations, our secured lenders could proceed against us and against the collateral securing that debt.Tax-Exempt FinancingsNew York Bonds. In fiscal year 2019, we completed the remarketing of $25,000 aggregate principal amount of New York Bonds 2014. As of December 31, 2019, we had outstanding $25,000 aggregate principal amount of New York Bonds 2014 and $15,000 aggregate principal amount of New York Bonds 2014R-2 issued by the New York State Environmental Facilities Corporation under the indenture dated December 1, 2014 (collectively, the “New York Bonds”).

We borrowed the proceeds of the Vermont Bonds to finance or refinance certain qualifying property, plant and equipment assets purchased in the state of Vermont.New Hampshire Bonds. In fiscal year 2019, we completed the remarketing of $11,000 aggregate principal amount of senior unsecured New Hampshire Bonds. As of December 31, 2019, we had outstanding $11,000 aggregate principal amount of New Hampshire Bonds. The New Hampshire Bonds, which are guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 2.95% per annum through maturity on April 1, 2029 and interest. During the fixed interest rate period, the New Hampshire Bonds are not supported by a letter of credit. Interest is payable on April 1 and October 1 of each year. We borrowed the proceeds of the New Hampshire Bonds to finance or refinance certain qualifying property, plant and equipment assets purchased in the state of New Hampshire.Loss on Debt ExtinguishmentIn order to lower our borrowing costs and reduce our market risk we completed the following transactions that resulted in a loss on debt extinguishment in fiscal years 2019, 2018 and 2017 of $0, $7,352 and $517, respectively:•the write-off of debt issuance costs and unamortized discount, in the case of our Term Loan B Facility in fiscal year 2018, associated with the refinancing of our previously outstanding senior secured credit facility in fiscal year 2018 and an amendment to our previously outstanding senior secured credit facility in fiscal year 2017: and•the write-off of debt issuance costs in connection with the remarketing of our Vermont Bonds in fiscal year 2018 and the remarketing of our Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-1 (“FAME Bonds 2005R-1”) and Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-2 (“FAME Bonds 2005R-2”) into the FAME Bonds 2005R-3 in fiscal year 2017.Interest ExpenseThe components of interest expense are as follows: Fiscal Year Ended December 31, 201920182017Interest expense on long-term debt and finance leases$22,553$23,431$22,060Amortization of debt issuance costs and discount on long-term debt2,2932,4492,692Letter of credit fees519554703Less: capitalized interest(263)(140)(295)Total interest expense$25,102$26,294$25,160Table of Contents9192 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 enter into interest rate derivative agreements to manage exposure to fluctuations in interest rates related to variable rate interest payments of our long-term debt. As of both December 31, 2019, and December 31, 2018, our interest rate derivative agreements had a total notional amount of $190,000. We receive interest based on the 1-month LIBOR index, restricted by a floor in certain instances, and pay interest at a weighted average rate of approximately 2.5% as of both December 31, 2019 and December 31, 2018. The agreements mature between February 2021 and May 2023. In fiscal year 2019, we entered into interest rate derivative agreements with a total notional amount of $65,000 that will serve to replace existing interest rate derivative agreements upon their expiration between February 2021 and February 2022. These forward starting interest rate derivative agreements mature between February 2026 and February 2027. We receive interest based on the 1-month LIBOR index, restricted by floor, and pay interest at a weighted average rate of approximately 1.8%. We have designated these derivative instruments as highly effective cash flow hedges, and therefore the change in fair value is recorded in our stockholders’ equity (deficit) as a component of accumulated other comprehensive loss and included in interest expense at the same time as interest expense is affected by the hedged transactions. Differences paid or received over the life of the agreements are recorded as additions to or reductions of interest expense on the underlying debt and included in cash flows from operating activities.A summary of the effect of cash flow hedges related to derivative instruments on the consolidated balance sheet follows:Fair ValueBalance Sheet LocationDecember 31,2019December 31,2018Interest rate swapsOther current assets$—$338Interest rate swapsOther non-current assets—482Total$—$820Interest rate swapsOther accrued liabilities$1,824$387Interest rate swapsOther long-term liabilities3,6031,555Total$5,427$1,942Interest rate swapsAccumulated other comprehensive loss, net$(5,929)$(1,196)Interest rate swaps - tax provisionAccumulated other comprehensive loss, net(112)(112)$(6,041)$(1,308)A summary of the amount of gain or (loss) on cash flow hedging relationships related to interest rate swaps reclassified from accumulated other comprehensive loss, net into earnings follows: Fiscal Year Ended December 31,201920182017Statement of Operations Location(Expense) IncomeInterest expense$(553)$(363)$(421)Fair Value of DebtAs of December 31, 2019, the fair value of our fixed rate debt, including the FAME Bonds, Vermont Bonds, New York Bonds and New Hampshire Bonds was approximately $131,357 and the carrying value was $122,000. The fair value of the FAME Bonds, Vermont Bonds, New York Bonds and 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 December 31, 2019, the carrying value of our Term Loan Facility was $350,000 and the carrying value of our Revolving Credit Facility was $26,900. Their fair values are based on current borrowing rates for similar types of borrowing arrangements, or Level 2 inputs, and approximate their carrying values. Table of Contents9293 Although we have determined the estimated fair value amounts of the FAME Bonds, Vermont Bonds, New York Bonds 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.

COMMITMENTS AND CONTINGENCIESIn 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.In accordance with FASB ASC 450 - Contingencies, we accrue for legal proceedings, inclusive of legal costs, when losses become probable and reasonably estimable. 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.Environmental Remediation Liability (including related litigation)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 our material outstanding claims.Table of Contents9394 Southbridge Recycling & Disposal Park, Inc.In October 2015, our Southbridge Recycling and Disposal Park, Inc. (“SRD”) subsidiary reported to the Massachusetts Department of Environmental Protection (“MADEP”) 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 SRD 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 are carrying out an Immediate Response Action pursuant to Massachusetts General Law Chapter 21E (the "Charlton 21E Obligations") pursuant to state law. Further, we have implemented a plan to analyze and better understand the groundwater near the Southbridge Landfill and we are investigating with the objective of identifying the source or sources of the elevated levels of contamination measured in the well samples. If it is determined that some or all of the contamination originated at the Southbridge Landfill, we will work with the Town (the Southbridge Landfill owner and the former operator of an unlined portion of the Southbridge Landfill, which was used prior to our operation of a double-lined portion of the Southbridge Landfill commencing in 2004) to evaluate and allocate the liabilities related to the Charlton 21E Obligations. In July 2016, we sent correspondence to the Town pursuant to Chapter 21E of Massachusetts General Laws demanding that the Town reimburse us for the environmental response costs we had spent and that the Town be responsible for all such costs in the future, as well as any other costs or liabilities resulting from the release of contaminants from the unlined portion of the Southbridge Landfill. The Town responded in September 2016, denying that the Southbridge Landfill is the source of such contamination, and claiming that if it is, that we may owe an indemnity to the Town pursuant to the Operating Agreement between us and the Town dated May 29, 2007, as amended. We entered into a Tolling Agreement with the Town to delay any further administrative or legal actions until our work with MADEP more specifically defines the parties’ responsibilities for the Charlton 21E Obligations, if any. Please see below for further discussion of our relationship with the Town regarding the Charlton 21E Obligations.In February 2016, we and the Town received a Notice of Intent to Sue under the Resource Conservation and Recovery Act ("RCRA") from a law firm purporting to represent residents proximate to the Southbridge Landfill (“Residents”), indicating its intent to file suit against us on behalf of the Residents alleging the groundwater contamination originated from the Southbridge Landfill. In February 2017, we received an additional Notice of Intent to Sue from the National Environmental Law Center under the Federal Clean Water Act ("CWA") and RCRA (collectively the “Acts”) on behalf of Environment America, Inc., d/b/a Environment Massachusetts, and Toxics Action Center, Inc., which have referred to themselves as the Citizen Groups. The Citizen Groups alleged that we had violated the Acts, and that they intended to seek appropriate relief in federal court for those alleged violations. On or about June 9, 2017, a lawsuit was filed against us, SRD and the Town in the United States District Court for the District of Massachusetts (the “Massachusetts Court”) by the Citizen Groups and the Residents alleging violations of the Acts (the “Litigation”), and demanding a variety of remedies under the Acts, including fines, remediation, mitigation and costs of litigation, and remedies for violations of Massachusetts civil law related to personal and property damages, including remediation, diminution of property values, compensation for lost use and enjoyment of properties, enjoinment of further operation of the Southbridge Landfill, and costs of litigation, plus interest on any damage award, on behalf of the Residents. We believe the Litigation to be factually inaccurate, and without legal merit, and we and SRD intend to vigorously defend the Litigation. Nevertheless, we believe it is reasonably possible that a loss will occur as a result of the Litigation although an estimate of loss cannot be reasonably provided at this time. We also continue to believe the Town should be responsible for costs or liabilities associated with the Litigation relative to alleged contamination originating from the unlined portion of the Southbridge Landfill, although there can be no assurance that we will not be required to incur some or all of such costs and liabilities.In December 2017, we filed a Motion to Dismiss the Litigation, and on October 1, 2018, the Massachusetts Court granted our Motion to Dismiss, and accordingly, dismissed the Citizen Groups claims under the Acts. The Massachusetts Court has retained jurisdiction of the Residents claims. The Citizen Groups intend to appeal the Massachusetts Court’s decision to grant our Motion to Dismiss. The Residents moved for a stay of their case until the Citizen Groups appealed. We opposed the stay and in March 2019, the Massachusetts Court denied the Residents motion for a stay. We are in active discovery in the Residents case.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 will issue a twenty (20) year bond for our portion of the Waterline costs (up to $5,000). 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. Remaining aspects of the project are minor and are expected to be completed in early 2020. Bond reimbursement to the Town will commence in the fiscal year ending December 31, 2020.Table of Contents9495 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 of 1.9%. Our expenditures could be significantly higher if costs exceed estimates. A summary of the changes to the environmental remediation liability associated with the Southbridge Landfill follows: Fiscal Year Ended December 31, 20192018Beginning balance$5,173$5,936Accretion expense124—Obligations incurred—152Obligations settled (1)(701)(915)Ending balance$4,596$5,173(1)Includes amounts that are being processed through accounts payable as a part of our disbursements cycle.We completed the first phase of landfill capping and closure in fiscal year 2019 at the Southbridge Landfill and are actively seeking approval from MADEP to close and cap the remainder of the landfill.The costs and liabilities we may be required to incur in connection with the foregoing Southbridge Landfill matters could be material to our results of operations, our cash flows and our financial condition.Potsdam Environmental Remediation LiabilityOn 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 (“GM”) 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 was completed in fiscal year 2019. 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. Our expenditures could be significantly higher if costs exceed estimates. 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 1.5%. A summary of the changes to the environmental remediation liability associated with the Potsdam site follows:Fiscal Year Ended December 31,20192018Beginning balance$5,614$5,758Obligations settled (1)(4,463)(171)Obligations incurred—27Ending balance$1,151$5,614(1)Includes amounts that are being processed through accounts payable as a part of our disbursements cycle.The total expected environmental remediation payments, in today’s dollars, for each of the five succeeding fiscal years and the aggregate amount thereafter are as follows:Table of Contents9596 Estimated Future Environmental Remediation Payments as of December 31, 2019Fiscal year ending December 31, 2020$446Fiscal year ending December 31, 2021382Fiscal year ending December 31, 2022392Fiscal year ending December 31, 2023367Fiscal year ending December 31, 2024386Thereafter4,630Total$6,603A reconciliation of the expected aggregate non-inflated, undiscounted environmental remediation liability to the amount recognized in the statement of financial position is as follows:Undiscounted liability$6,603Less discount, net(856)Liability balance - December 31, 2019$5,747Any substantial liability incurred by us arising from environmental damage could have a material adverse effect on our business, financial condition and results of operations. We are not presently aware of any other situations that would have a material adverse impact on our business, financial condition, results of operations or cash flows.Legal Proceedings North Country Environmental ServicesOn or about March 8, 2018, the Citizen Groups described above delivered correspondence to our subsidiary, North Country Environmental Services, Inc. ("NCES") and us, providing notice of the 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 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. On June 15, 2018, we and NCES filed a Motion to Dismiss the New Hampshire Litigation. On July 13, 2018, the 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 circuits were heard by the Supreme Court of the United States (“SCOTUS”). SCOTUS has granted certiorari determining that the circumstances described are sufficient for SCOTUS to hear such cases. Our motion for a stay was granted in the New Hampshire Litigation, and SCOTUS is expected to hear and rule on such cases this calendar year. In any event, we intend to continue to vigorously defend against the New Hampshire Litigation, which we believe is without merit.Ontario County, New York Class Action LitigationOn or about September 17, 2019, Richard Vandemortel and Deb Vandemortel filed a class action complaint against us on behalf of similarly situated citizens in Ontario County, New York. The lawsuit has been filed in Ontario County (the “New York Litigation”). It 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 Ontario County Landfill, 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. We are reviewing the New York Litigation and intend to present a vigorous defense.Loss Contingency On January 9, 2019, NCES filed an application for a 1.2 million (cy) expansion of the capacity of the NCES Landfill with the New Hampshire Department of Environmental Services (“NHDES”) (“Stage VI Expansion”). The Stage VI Expansion would provide NCES with over five (5) years of additional capacity beyond the capacity of Stage V.Table of Contents9697 In January 2020, NHDES informed NCES and us that NHDES had concerns regarding the short-term public benefit need for the Stage VI expansion, and also in respect of certain technical concerns regarding the Stage VI expansion. Given the fact the NHDES decided to review our permit application for the Stage VI Expansion with respect to public benefit determination using a different regulatory framework than used in any of our previous permitting activities at NCES, we informed the NHDES on February 11, 2020, that while we vigorously disagreed with NHDES’ review of our application and the context for the NHDES’ concerns, we would withdraw our application with the expectation of refiling the application with the NHDES as soon as possible. While the refiling of the application for the Stage VI Expansion could be rejected by the NHDES, and while delay of the Stage VI Expansion will surely occur, we remain confident that we will receive a permit for the Stage VI Expansion. We believe that a loss of $1,195 is reasonably possible, but not probable.Employment ContractsWe have entered into employment contracts with five of our executive officers. The contracts are dated June 18, 2001, March 31, 2006, July 6, 2010, September 1, 2012 and March 1, 2016. Each contract had an initial term between one and three years and a covenant not-to-compete ranging from one to two years from the date of termination. These contracts automatically extend for a one year period at the end of the initial term and any renewal period. Total annual commitments for salaries under these contracts are $1,937. In the event of a change in control of us, or in the event of involuntary termination without cause, the employment contracts provide for a payment ranging from one to three years of salary and bonuses. We also have other employment contracts or arrangements with employees who are not executive officers.13. STOCKHOLDERS' EQUITYPublic Offering of Class A Common StockIn fiscal year 2019, we completed a public offering of 3,565 shares of our Class A common stock at a public offering price of $29.50 per share. The offering resulted in net proceeds to us of $100,446, after deducting underwriting discounts and commissions and offering expenses. The net proceeds from the offering were and are to be used for general corporate purposes, including potential acquisitions or development of new operations or assets with the goal of complementing or expanding our business, working capital and capital expenditures.In fiscal year 2019, we completed the unregistered sale of 59 shares of our Class A common stock at a price of $44.15 per share. The sale resulted in net proceeds to us of $2,619. The shares were previously held in escrow according to the terms of our acquisition of WSI and released to us for liquidation to offset costs associated with the environmental remediation of the WSI's Potsdam, New York site. We recorded a $2,619 reduction of goodwill in line with business combination standards in place at the time the shares held in escrow were issued. See Note 12, Commitments and Contingencies for additional disclosure.Common StockThe holders of the Class A common stock are entitled to one vote for each share held. The holders of the Class B common stock are entitled to ten votes for each share held, except for the election of one director, who is elected by the holders of the Class A common stock exclusively. The Class B common stock is convertible into Class A common stock on a share-for-share basis at the option of the shareholder.Preferred StockWe are authorized to issue up to 944 shares of preferred stock in one or more series. As of December 31, 2019 and December 31, 2018, we had no shares issued.Stock Based CompensationStock Incentive Plans2006 Stock Incentive Plan. In the fiscal year ended April 30, 2007, we adopted the 2006 Stock Incentive Plan (“2006 Plan”). The 2006 Plan was amended in the fiscal year ended April 30, 2010. The 2006 Plan terminated as of October 9, 2016 and as a result no additional awards may be made pursuant to the 2006 Plan. Outstanding shares which are not actually issued under the 2006 Plan because such awards expire or otherwise result in shares not being issued are reserved for issuance under the 2016 Plan.2016 Incentive Plan. In fiscal year 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 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 or otherwise result in shares not being issued. Table of Contents9798 As of December 31, 2019, there were 1,361 Class A common stock equivalents available for future grant under the 2016 Plan, inclusive of additional Class A common stock equivalents that were previously issued under terminated plans and have become available for grant because such awards expired or otherwise resulted in shares not being issued. Our equity awards granted consist of stock options, including market-based performance stock options, restricted stock, restricted stock units and performance stock units, including market-based performance stock units.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, with the exception of market-based performance stock option grants, 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. The fair value of each market-based performance stock option granted is estimated using a Monte Carlo option-pricing model, which also 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, but also including estimates of share price appreciation of our Class A common stock as compared to the Russell 2000 Index over the requisite service period.Restricted stock, restricted stock units and 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 the value of dividends of our Class A common stock as compared to the Russell 2000 Index over the requisite service period.Restricted stock 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 vest incrementally over an identified service period beginning on the grant date based on continued employment. Performance stock units and 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.Stock OptionsA summary of stock option activity is as follows:Stock OptionsWeightedAverageExercise PriceWeightedAverageRemainingContractualTerm (years)AggregateIntrinsic ValueOutstanding, December 31, 2018669$6.37Granted—$—Exercised(571)$5.88Forfeited or expired—$—Outstanding, December 31, 201998$9.205.8$3,614Exercisable, December 31, 201998$9.205.8$3,614During fiscal years 2019, 2018 and 2017, stock-based compensation expense for stock options was $0, $473 and 644, respectively.During fiscal years 2019, 2018 and 2017, the aggregate intrinsic value of stock options exercised was $19,475, $1,916 and $4,664, respectively.As of December 31, 2019, there was no remaining unrecognized stock-based compensation expense related to outstanding stock options.Our calculation of stock-based compensation expense associated with stock options granted, with the exception of market-based performance stock option grants which are valued using a Monte Carlo option-pricing model, was made using the Black-Scholes valuation model. We did not grant any new stock options in fiscal years 2019, 2018 or 2017.Table of Contents9899 Expected life is calculated based on the weighted average historical life of the vested stock options, giving consideration to vesting schedules and historical exercise patterns. Risk-free interest rate is based on the U.S. Treasury yield curve for the period of the expected life of the stock option. Expected volatility is calculated using the weekly historical volatility of our Class A common stock over the expected life, except in the case of market-based performance stock option where the daily historical volatility of our Class A common stock over the expected life is used.The Black-Scholes valuation model and the Monte Carlo option-pricing model each require extensive use of accounting judgment and financial estimation. Application of alternative assumptions could produce significantly different estimates of the fair value of stock-based compensation and consequently, the related amounts recognized in the consolidated statements of operations.Other Stock AwardsA summary of restricted stock, restricted stock unit and performance stock unit activity is as follows:Restricted Stock,Restricted Stock Units,and Performance StockUnits (1)WeightedAverageGrant PriceWeighted AverageRemainingContractual Term(years)Aggregate IntrinsicValueOutstanding, December 31, 2018686$15.56Granted166$37.24Class A common stock vested(449)$12.38Forfeited or canceled(10)$23.41Outstanding, December 31, 2019393$28.231.3$6,992Unvested, December 31, 2019579$29.691.4$9,458(1)Market-based performance stock unit grants are included at 100%. Attainment of maximum performance targets and market achievements would result in the issuance of an additional 186 shares of Class A common stock currently included in unvested. The market-based performance stock unit grants that vested in fiscal year 2019 resulted in the issuance of 178 additional shares of Class A common stock.During fiscal years 2019, 2018 and 2017, stock-based compensation expense related to restricted stock, restricted stock units and performance stock units was $7,036, $7,821 and $5,652, respectively. During fiscal years 2019, 2018 and 2017, the total fair value of other stock awards vested was $8,177, $10,529 and $5,706, respectively.As of December 31, 2019, total unrecognized stock-based compensation expense related to restricted stock units was $3,156, which will be recognized over a weighted average period of 1.2 years. Total unrecognized stock-based compensation expense related to performance stock units, assuming the attainment of maximum performance targets, was $6,051, which will be recognized over a weighted average period of 1.5 years. The weighted average fair value of market-based performance stock units granted during fiscal year 2019 was $38.74 per award, which was calculated using a Monte Carlo pricing model assuming a risk free interest rate of 2.28% and an expected volatility of 30.9% assuming no expected dividend yield. Risk-free interest rate is based on the U.S. Treasury yield curve for the expected service period of the award. Expected volatility is calculated using the daily volatility of our Class A common stock over the expected service period of the award.The Monte Carlo pricing model requires extensive use of accounting judgment and financial estimation. Application of alternative assumptions could produce significantly different estimates of the fair value of stock-based compensation and consequently, the related amounts recognized in the consolidated statements of operations.We also recorded $186, $150 and $136 of stock-based compensation expense related to our Amended and Restated 1997 Employee Stock Purchase Plan during fiscal years 2019, 2018 and 2017, respectively.Tax (benefits) provisions for income taxes associated with stock-based compensation during fiscal years 2019, 2018 and 2017 of $(291), $(23) and $117, respectively.

FAIR VALUE OF FINANCIAL INSTRUMENTSWe 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.Assets and Liabilities Accounted for at Fair Value on a Recurring BasisOur 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 derivatives, 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 interest rate derivatives 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. See Note 11, Debt for disclosure over the fair value of debt.Table of Contents100101 Recurring Fair Value MeasurementsSummaries of our financial assets and liabilities that are measured at fair value on a recurring basis are as follows: Fair Value Measurement at December 31, 2019 Using:Quoted Prices inActive Markets forIdentical Assets(Level 1)Significant OtherObservable Inputs(Level 2)SignificantUnobservable Inputs(Level 3)Assets:Restricted investment securities - landfill closure$1,586$—$—Liabilities:Interest rate swaps$—$5,427$—Fair Value Measurement at December 31, 2018 Using:Quoted Prices inActive Markets forIdentical Assets(Level 1)Significant OtherObservable Inputs(Level 2)SignificantUnobservable Inputs(Level 3)Assets:Restricted investment securities - landfill closure$1,248$—$—Interest rate swaps—820—$1,248$820$—Liabilities:Interest rate swaps$—$1,942$—15. EMPLOYEE BENEFIT PLANSDefined Contribution PlanWe offer our eligible employees the opportunity to contribute to a 401(k) plan (“401(k) Plan”). Under the provisions of the 401(k) Plan participants may direct us to defer a portion of their compensation to the 401(k) Plan, subject to Internal Revenue Code limitations. We provide an employer matching contribution equal to fifty cents for every dollar an employee invests in the 401(k) Plan up to our maximum match of one thousand dollars per employee per calendar year, subject to revision. Participants vest in employer contributions ratable over a three year period. Employer contributions for fiscal years 2019, 2018 and 2017 amounted to $1,608, $1,319 and $1,817, respectively.Employee Stock Purchase PlanWe offer our eligible employees the opportunity to participate in an employee stock purchase plan. Under this plan, qualified employees may purchase shares of Class A common stock by payroll deduction at a 15% discount from the market price. During fiscal years 2019, 2018 and 2017, 23, 26 and 41 shares, respectively, of Class A common stock were issued under this plan. As of December 31, 2019, 94 shares of Class A common stock were available for distribution under this plan.Multiemployer Pension PlanWe make contributions to a multiemployer defined benefit pension plan, the New England Teamsters and Trucking Industry Pension Fund (the “Pension Plan”), under the terms of a collective bargaining agreement (“CBA”) that covers certain of our union represented employees. The Pension Plan provides retirement benefits to participants based on their service to contributing employers. We do not administer the Pension Plan. The risks of participating in a multiemployer pension plan are different from a single-employer pension plan in that: (i) assets contributed to the multiemployer pension plan by one employer may be used to provide benefits to employees or former employees of other participating employers; (ii) if a participating employer stops contributing to the plan, the unfunded obligations of the plan may be required to be assumed by the remaining participating employers; and (iii) if we choose to stop participating in our multiemployer Pension Plan, we may be required to pay the plan a withdrawal amount based on the underfunded status of the plan.Table of Contents101102 In October 2019, we reached an agreement to withdraw from the Pension Plan by entering into Withdrawal and Re-entry Agreements with the Pension Plan. In accordance with FASB ASC 450 - Contingencies, because of our withdrawal from the Pension Plan, we recorded an obligation of $3,194 as of September 30, 2019 and a charge of $3,591 as pension withdrawal expense, offset by a $397 retroactive contribution credit recorded as cost of operations, in fiscal year 2019. While the withdrawal generates a fixed yearly contingent liability for us for a period of approximately seventeen (17) years, it caps our gross payments at $4,224 significantly reducing our cash exposure from the potential $18,511 withdrawal liability as determined based on a complete withdrawal. As per the Re-entry Agreements and upon withdrawal, we re-entered the Pension Plan with certainty from a liability perspective. We have not, however, changed the terms of our CBA with Local 170, which remains in effect until June 30, 2020. As of December 31, 2019, we had a remaining obligation of $1,838 associated with our withdrawal.The following table outlines the status of the Pension Plan:Pension FundEIN/PensionPlan NumberPension Protection Act Zone Status Funding Improvement or Rehabilitation Plan StatusContributions to PlanExpiration Date of CBAFiscal Year Ended December 31,20192018201920182017New England Teamsters and Trucking Industry Pension Fund04-6372430Critical and decliningCritical and decliningImplemented$409$726$627June 30, 2020The status is based on the latest plan information for the plan year ended September 30, 2019 that we received from the Pension Plan and is certified by the Pension Plans’ actuary. Plans with a “critical and declining” status are funded at less than 65%, have a projected funding deficiency in the current or next four plan years and have a projected insolvency date which is less than the 20-year minimum statutory requirement. Our contributions to the Pension Plan represent less than 5% of total contributions to such plan for the plan year ended September 30, 2018 and a rehabilitation plan has been implemented with no surcharge imposed. Under current law regarding multiemployer benefit plans, a plan’s termination, our voluntary withdrawal, or the withdrawal of all contributing employers from any under-funded multiemployer pension plan would require us to make payments to the plan for our proportionate share of the multiemployer plan’s unfunded vested liabilities. We could have adjustments to estimates for these matters in the near term that could have a material effect on its consolidated financial position, results of operations or cash flows. At the date these financial statements were issued, a Form 5500 was not available for the plan year ended September 30, 2019.16. INCOME TAXESA summary of the benefit for income taxes is as follows: Fiscal Year Ended December 31, 201920182017FederalCurrent$(951)$(1,902)$—Deferred(699)1,255(15,614)(1,650)(647)(15,614)StateCurrent3212,575301Current benefit of loss carryforwards—(2,307)(28)Deferred(545)(5)88(224)263361Benefit for income taxes$(1,874)$(384)$(15,253)Table of Contents102103 During fiscal years 2019 and 2018, we recognized a $(2,385) and $(937) deferred tax benefit, respectively, due to a reduction of the valuation allowance on acquisitions. In determining the need for a valuation allowance, we have assessed the available means of recovering deferred tax assets, including the existence of reversing temporary differences. The valuation allowance decreased due to the recognition of additional reversing temporary differences from the $2,385 and $937 deferred tax liability recorded through goodwill on the acquisition of a company in May 2019 and the acquisition of two companies in January 2018, respectively. The deferred tax liabilities related to the acquisitions were based on the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for income tax purposes. The valuation allowance was reduced by $(2,137) and $(1,635) in the quarters ended June 30, 2019 and March 31, 2018, respectively, with the offsetting increase in the goodwill, based on initial estimates of the acquired temporary differences. The valuation allowance was decreased by $(248) in the quarter ended December 31, 2019 and increased by $698 in subsequent quarters of fiscal year 2018, with an offsetting adjustment to goodwill, based on the availability of better estimates upon the filing of the prior year returns by the sellers. During 2019, we recognized a $(297) deferred tax benefit due to a reduction of the deferred tax liability related to indefinite lived assets. The financial statement value of indefinite lived goodwill was reduced as a result of a settlement of an acquisition contingency that pre-dated the effective date of ASC 805, which resulted in a reduction of the related deferred tax liability. On December 22, 2017, the Tax Cuts and Jobs Act was enacted. The Tax Cuts and Jobs Act, which is also commonly referred to as “U.S. tax reform,” significantly changes United States corporate income tax laws by, among other things, reducing the US corporate income tax rate from 35% to 21% starting in 2018. Under the Tax Cuts and Jobs Act, federal net operating loss carryforwards generated as of the end of 2017 continue to be carried forward for 20 years and are generally available to fully offset taxable income earned in a tax year. Federal net operating losses generated after 2017 will be carried forward indefinitely, but generally may only offset up to 80% of taxable income earned in future tax years. In fiscal year 2017, we revalued our deferred taxes due to these changes, including (a) revaluing our federal net deferred taxes before valuation allowance using the 21% tax rate resulting in an increased net federal deferred tax provision of $33,700; (b) revaluing our federal valuation allowance using the 21% tax rate, including the impact of tax planning strategies, resulting in a federal deferred tax benefit to continuing operations of $(36,556); and (c) recognizing a federal deferred tax benefit of $(12,758) for 80% of indefinite lived deferred tax liabilities, which are anticipated to be available as a source of taxable income upon reversal of deferred tax assets that would also have indefinite lives.The differences in the benefit for income taxes and the amounts determined by applying the Federal statutory rate to income before provision for income taxes are as follows: Fiscal Year Ended December 31, 201920182017Federal statutory rate21%21%35%Tax at statutory rate$6,254$1,268$(12,968)State income taxes, net of federal benefit(161)(89)(1,959)Decrease in net federal deferred tax assets before valuation allowance change due to federal rate change——33,700Decrease in valuation allowance by 80% of indefinite lived deferred liabilities due to US tax reform——(12,758)Other changes in valuation allowance, including the federal rate change in fiscal year 2017(978)(1,613)(18,848)Deductible stock awards(7,235)(2,048)(1,825)Non-deductible expenses638633542Non-deductible officer compensation3142,214—Tax credits(82)(686)(1,000)Other, net(624)(63)(137)Benefit for income taxes$(1,874)$(384)$(15,253)Table of Contents103104 Deferred income taxes reflect the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for income tax purposes. A summary of deferred tax assets and liabilities is as follows: December 31, 20192018Deferred tax assets:Net operating loss carryforwards$45,900$31,241Accrued expenses and reserves36,34234,647General business tax credit carryforwards6,2736,192Book over tax depreciation of property and equipment2,88219,048Unrealized loss on hedges and swaps1,768—Stock awards1,7462,310Alternative minimum tax credit carryforwards9511,902Other2,5763,023Total deferred tax assets98,43898,363Less: valuation allowance(69,402)(69,189)Total deferred tax assets after valuation allowance29,03629,174Deferred tax liabilities:Amortization of intangibles(22,910)(22,026)Other(192)(73)Total deferred tax liabilities(23,102)(22,099)Net deferred tax asset $5,934$7,075The net deferred tax asset at December 31, 2019 is reflected on the balance sheet as a long-term deferred federal tax asset of $8,577 and a long-term deferred state tax liability of $(2,643).As of December 31, 2019, we have, for federal income tax purposes, net operating loss carryforwards of approximately $110,587 that expire in the fiscal years ending December 31, 2031 through 2037 and $67,399, which do not expire. We have state net operating loss carryforwards of approximately $101,628 that expire in the fiscal years ending December 31, 2020 through 2039. In addition, we have $951 minimum tax credit carryforwards which are fully refundable for tax years 2020 through 2021, if not otherwise used to offset tax liabilities. We also have $6,273 general business credit carryforwards which expire in the fiscal years ending December 31, 2022 through 2039. Sections 382 and 383 of the Internal Revenue Code can limit the amount of net operating loss and credit carryforwards which may be used in a tax year in the event of certain stock ownership changes. With the exception of $1,756 federal net operating losses we acquired through acquisitions, we are not currently subject to these limitations but could become subject to them if there were significant changes in the ownership of our stock.In assessing the realizability of carryforwards and other deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. We adjust the valuation allowance in the period management determines it is more likely than not that deferred tax assets will or will not be realized. The change in the valuation allowance was an increase of $213 and $834 from fiscal years 2019 and 2018, respectively. In determining the need for a valuation allowance, we have assessed the available means of recovering deferred tax assets, including the ability to carryback net operating losses, the existence of reversing temporary differences, and available sources of future taxable income. We have also considered the ability to implement certain strategies, such as a potential sale of assets that would, if necessary, be implemented to accelerate taxable income and use expiring deferred tax assets.The net deferred tax assets include deferred tax liabilities related to amortizable goodwill, which are anticipated to reverse in an indefinite future period and to generate future taxable income upon reversal. Prior to the Tax Cuts and Jobs Act, federal net operating losses, including potential losses from the reversal of deferred tax assets, could only be carried forward for 20 years. The reversal of the indefinite lived goodwill was not available as a source of future taxable income since it was uncertain whether the income generated would be available in the same tax periods in which losses from the reversal of deferred tax assets could be utilized. As such, prior to the Tax Cuts and Jobs Act we did not treat the reversal of amortizable goodwill as an available source of taxable income in determining the valuation allowance.Table of Contents104105 Beginning in 2018 under the Tax Cuts and Jobs Act, future federal net operating losses generated may be carried forward indefinitely and generally may offset up to 80% of taxable income earned in a tax year. Because potential losses from the reversal of deferred tax assets in future years may be carried forward indefinitely, we consider it more likely than not that 80% of the reversal of deferred tax liabilities for amortizable goodwill will be available as a source of taxable income.In the fourth quarter of 2017, we revalued our net federal deferred tax assets using the 21% tax rate as enacted under the Tax Cuts and Jobs Act. The valuation allowance was also adjusted in this quarter due to the federal tax rate change and to recognize a $(12,758) federal deferred tax benefit for 80% of deferred tax liabilities for amortizable goodwill. Due to the Tax Cuts and Jobs Act, we recognized a $(15,614) federal deferred tax benefit in 2017 and decreased our total valuation allowance by $(29,234). We believe we are able to support the deferred tax assets recognized as of the end of fiscal years 2019 and 2018 based on all of the available evidence.The provisions of FASB ASC 740-10-25-5 prescribe the minimum recognition threshold that a tax position is required to meet before being recognized in the financial statements. Additionally, FASB ASC 740-10-25-5 provides guidance on de-recognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. Under FASB ASC 740-10-25-5, an entity may only recognize or continue to recognize tax positions that meet a “more likely than not” threshold.A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows:Fiscal Year Ended December 31,20192018Unrecognized tax benefits at beginning of period$2$1,941Reductions resulting from lapse of statute of limitations(1)(1,939)Unrecognized tax benefits at end of period$1$2The fiscal year 2018 reductions resulting from a lapse of the statute of limitations primarily related to unrecognized benefits which had reduced net operating loss carryforwards. The tax positions primarily related to fiscal years 2007 and prior and, based on administrative practice of the tax authorities, we have reduced the unrecognized tax benefits.Included in the balances at December 31, 2019 and December 31, 2018 are $1 and $2, respectively, of unrecognized tax benefits (net of the federal benefit on state issues) that, if recognized, would favorably affect the effective income tax rate in future periods. We anticipate $0 of unrecognized tax benefits to reverse within the next 12 months due to the expiration of the applicable statute of limitations.Our continuing practice is to recognize interest and penalties related to income tax matters in income tax expense. Related to uncertain tax positions during fiscal years 2019, 2018 and 2017, we have accrued interest of $1, $2 and $3 and penalties of $1, $1 and $2, respectively. We accrued $(1), $(2) and $(3) for interest and penalties in income tax expense related to uncertain tax positions during fiscal years 2019, 2018 and 2017, respectively. To the extent interest and penalties are not assessed with respect to uncertain tax positions, amounts accrued will be reduced and reflected as a reduction of the overall income tax provision.We are subject to U.S. federal income tax, as well as income tax of multiple state jurisdictions. Due to Federal and state net operating loss carryforwards, income tax returns from years ending in 1998 through 2019 remain open for examination, with limited exceptions.Table of Contents105106 17. OTHER ITEMS AND CHARGESSouthbridge Landfill Closure Charge, NetIn June 2017, we initiated the plan to cease operations of our Southbridge Landfill and later closed it in November 2018 when Southbridge Landfill reached its final capacity. Accordingly, in fiscal years 2019, 2018 and 2017, we recorded charges associated with the closure of our Southbridge Landfill as follows: Fiscal Year Ended December 31, 201920182017Asset impairment charge (1)$—$—$47,999Project development charge (2)——9,149Environmental remediation charge (3)——6,379Contract settlement charge (4)—8,724—Landfill closure project charge (5)—6,012—Charlton settlement charge (6)—1,216—Legal and transaction costs (7)2,7092,1021,656Recovery on insurance settlement (8)—(10,000)—Southbridge Landfill closure charge, net$2,709$8,054$65,183(1)We performed a test of recoverability under FASB ASC 360, which indicated that the carrying value of our asset group that includes the Southbridge Landfill was no longer recoverable and, as a result, the asset group was assessed for impairment with an impairment charge allocated to the long-lived assets of the Southbridge Landfill in accordance with FASB ASC 360. (2)We wrote-off deferred costs associated with Southbridge Landfill permitting activities no longer deemed viable. (3)We recorded an environmental remediation charge associated with the installation of a municipal waterline. (4)We recorded a contract settlement charge associated with the closure of Southbridge Landfill and the remaining future obligations due to the Town of Southbridge under the landfill operating agreement with the Town of Southbridge. (5)We recorded a landfill closure project charge associated with increased costs under the revised closure plan at our Southbridge Landfill.(6)We established a reserve associated with settlement of the Town of Charlton's claim against us. (7)We incurred legal costs as well as other costs associated with various matters as part of the Southbridge Landfill closure. (8)We recorded a recovery on an environmental insurance settlement associated with the Southbridge Landfill closure. Expense from Acquisition Activities and Other ItemsIn fiscal year 2019, we recorded a charge of $2,687 associated primarily with acquisition activities. In fiscal year 2018, we recorded a charge of $1,872 associated with acquisition activities and the write-off of deferred costs related to the expiration of our shelf registration statement, and in fiscal year 2017, we recorded a charge of $176 associated with acquisition activities. See Note 5, Business Combinations for disclosure over acquisition activity.Contract Settlement Charge In fiscal year 2018, we recorded contract settlement charges of $2,100 associated with the termination and discounted buy-out of a commodities marketing and brokerage agreement. Development Project Charge In fiscal year 2018, we recorded a development project charge of $311 associated with previously deferred costs that were written off as a result of the negative vote in a public referendum relating to the NCES Landfill.Table of Contents106107 18.

RELATED PARTY TRANSACTIONSServices During fiscal years 2019, 2018 and 2017, we retained the services of Casella Construction, Inc. ("CCI"), a company substantially owned by sons of John Casella, our Chairman and Chief Executive Officer, and Douglas Casella, a member of our Board of Directors, as a contractor in developing or closing certain landfills owned by us as well as providing transportation services. Total purchased services charged to operations or capitalized to landfills for fiscal years 2019, 2018 and 2017 were $7,990, $3,442 and $3,398, respectively, of which $851 and $32 were outstanding and included in either accounts payable or other current liabilities as of December 31, 2019 and December 31, 2018, respectively.In addition to the total purchased services, we provided various waste collection and disposal services to CCI. Total revenues recorded for fiscal years 2019, 2018 and 2017 were $132, $156 and $237, respectively. LeasesIn the fiscal year ended April 30, 1994, we entered into two leases for operating facilities with a partnership of which John Casella, our Chairman and Chief Executive Officer, and Douglas Casella, a member of our Board of Directors, are the general partners. The leases have since been extended through August 2023. The terms of the lease agreements require monthly payments of approximately $29. Total expense charged to operations for fiscal years 2019, 2018 and 2017 under these agreements was $339, $349 and $360, respectively.Landfill Post-closureWe have agreed to pay the cost of post-closure on a landfill owned by John Casella, our Chairman and Chief Executive Officer, and Douglas Casella, a member of our Board of Directors. We paid the cost of closing this landfill in 1992, and the post-closure maintenance obligations are expected to last until the fiscal year ending December 31, 2024. In fiscal years 2019, 2018 and 2017, we paid $9, $14 and $27, respectively, pursuant to this agreement. As of December 31, 2019 and December 31, 2018, we have accrued $37 and $48, respectively, for costs associated with its post-closure obligations.Table of Contents107108 20. SEGMENT REPORTINGWe report selected information about 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 and disposal, landfill, landfill gas-to-energy, transfer and recycling services in the northeastern United States. Our revenues in the Recycling segment are derived from municipalities and customers in the form of processing fees, tipping fees and commodity sales. Organics services, ancillary operations, along with major account and industrial services, are included in our Other segment. Effective January 1, 2020, we reorganized our operating segments as follows: we aligned our organics services and our major account and industrial services, with our Recycling segment to form the Resource Solutions segment, thus creating a single resource renewal-focused segment. We also moved our ancillary transportation services, which were previously included in our Other segment, into our Western region. Accordingly, as of January 1, 2020, our operating segments consist of the Eastern and Western regions and Resource Solutions.

This seasonality reflects the lower volume of waste during the late fall, winter and early spring months. Since certain of our operating and fixed costs remain constant throughout fiscal year, operating income is impacted by a similar seasonality. In addition, particularly harsh weather conditions typically result in increased operating costs.Our recycling business experiences increased volumes of newspaper in November and December due to increased retail activity during the holiday season.ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Table of Contents109110 ITEM 9A. CONTROLS AND PROCEDURESEvaluation of Disclosure Controls and ProceduresOur management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2019. 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, 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 Securities Exchange Act of 1934, as amended, 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 Securities Exchange Act of 1934, as amended, 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 December 31, 2019, 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.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2019. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework in 2013. Based on its assessment, management concluded that, as of December 31, 2019, our internal control over financial reporting is effective based on those criteria. The effectiveness of our internal control over financial reporting as of December 31, 2019 has been audited by RSM US LLP, an independent registered public accounting firm. RSM US LLP has issued an attestation report on our internal control over financial reporting, which is included herein.We completed the acquisitions of TAM, Inc., TAM Recycling, LLC, TAM Organics, LLC., North Rd. LLC, 171 Church Street, LLC (collectively, "TAM") on June 1, 2019; Allied Waste Services of North America, LLC, Browning-Ferris Industries of New York, Inc., Allied Waste Services of Massachusetts, LLC, and Menands Environmental Solutions, LLC (collectively, "Republic") on September 3, 2019; PSI Disposal Inc. ("PSI") on October 1, 2019; Trash Away, LLC ("Trash Away") on September 13, 2019; and LT Disposal Inc., River Road Transfer Station Inc., Center Point Transfer Station, Inc. (collectively, "Center Point") on September 13, 2019. Since we have not yet fully incorporated the internal controls and procedures of TAM, Republic, PSI, Trash Away and Center Point into our internal control over financial reporting, management excluded TAM, Republic, PSI, Trash Away and Center Point from its assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2019. Collectively, TAM, Republic, PSI, Trash Away and Center Point constituted approximately 7.1% of our total assets as of December 31, 2019 and 2.0% of our total revenues for the year ended December 31, 2019.Changes in Internal Control Over Financial ReportingNo change in our internal control over financial reporting occurred during the fiscal quarter ended December 31, 2019 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.ITEM 9B.
