ITEM 1. BUSINESS

Overview

Founded in 1975 with a single truck, Casella Waste Systems, Inc., a Delaware corporation, its wholly-owned subsidiaries and certain 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. We provide resource management expertise and services to residential, commercial,

3

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 manage our solid waste operations on a geographic basis through two regional operating segments, the Eastern and Western regions, each of which provides a full range of solid waste services, and our larger-scale recycling and commodity brokerage operations through our Recycling segment. Organics services, ancillary operations, industrial services, discontinued operations, and earnings from equity method investees, as applicable, are included in our Other segment.

As of January 29, 2016, we owned and/or operated 34 solid waste collection operations, 44 transfer stations, 18 recycling facilities, nine Subtitle D landfills, four landfill gas-to-energy facilities and one landfill permitted to accept construction and demolition (“C&D”) materials.

Change in Fiscal Year

In June 2014, we elected to change our fiscal year-end from April 30^th to December 31^st. This change in fiscal year became effective for our fiscal year beginning January 1, 2015 and ended December 31, 2015. As a result of this change, we filed a Transition Report on Form 10-KT for the eight-month transition period ended December 31, 2014. The references in this Annual Report on Form 10-K to the terms listed below reflect the respective period noted (all other reporting periods defined separately):

Term	Financial Reporting Period
fiscal year 2015	January 1, 2015 through December 31, 2015
calendar year 2014	January 1, 2014 through December 31, 2014 (Unaudited)
transition period 2014	May 1, 2014 through December 31, 2014
eight month period 2013	May 1, 2013 through December 31, 2013 (Unaudited)
fiscal year 2014	May 1, 2013 through April 30, 2014
fiscal year 2013	May 1, 2012 through April 30, 2013

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 several years, many of our customers have been seeking to reduce their environmental footprint by increasing their recycling rates, diverting organics materials out of the waste stream into beneficial use processes and exploring emerging methods to transform traditional waste streams into renewable resources. 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 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 in order to strive to maximize long-term financial returns and competitive positioning.

Over the last three years we have made significant progress in simplifying our business structure, improving cash flows and reducing risk exposure by divesting and closing underperforming operations that did not enhance or complement our core operations. Specifically, we have had success over the last three years improving our financial performance and driving positive cash flows by advancing efforts in four key areas: (1) increasing landfill returns; (2) driving additional profitability at collection operations; (3) creating incremental value through resource solutions; and (4) improving our balance sheet and reducing business risk. We plan to continue to focus our efforts in these areas in the fiscal year ending December 31, 2016. To support our efforts, we continue to invest in our employees through leadership development, technical training, and incentive compensation structures that seek to align our employees’ incentives with our long-term goal to improve returns on invested capital.

Increasing landfill returns

We launched a strategic initiative in fiscal year 2014 to source incremental waste volumes to our landfills to maximize annual capacity utilization and increase cash flows. Our goal was to increase waste volumes by 0.5 million tons annually to our landfills by the end of fiscal year 2015. As of December 31, 2015, we had exceeded this goal, with overall landfill volumes for fiscal year 2015 up by approximately 0.8 million tons per year compared to the twelve months ended December 31, 2012, excluding volumes from the Worcester landfill closure project in Massachusetts.

4

Landfill waste volume increases have been primarily driven by: (1) our success in acquiring new transfer station and hauling customers; (2) increasing waste volumes at our Southbridge landfill (“Southbridge”) in Southbridge, Massachusetts and our Waste USA landfill (“Waste USA”) in Coventry, Vermont, in accordance with increased annual permit limits; (3) increasing C&D volumes as the construction market began to slowly rebound across several of our market areas; (4) our focused landfill sales strategy, which included the revamping of our special waste team to focus on sourcing additional industrial and remediation waste volumes; and (5) our asset positioning in several key markets that have contracting permitted capacity.

Disposal market dynamics have quickly shifted across our footprint due to improving macroeconomic conditions and a challenging regulatory environment for new disposal capacity. In total, facilities that we estimate had approximately 1.7 million tons of annual disposal capacity have permanently closed in Massachusetts, Maine, New Hampshire, and Vermont over the last two years, and we expect that facilities with another 1.2 million tons of additional annual capacity will permanently close over the next several years. These closures and expected closures represent a reduction of over 20% of total market capacity across these states. Furthermore, we expect that waste flow shifts in New York State and additional facility closures in contiguous markets will keep more waste volumes in the market for ultimate disposal over the next 20 years, further tightening available market capacity.

Given this backdrop, we shifted our landfill strategy in transition period 2014 to balance sourcing additional volumes against improving pricing and returns at our landfills. While we believe it will take several years for the capacity constraints in our markets to become acute, we experienced tightening pricing elasticity in our markets over the last year, which has enabled us to begin increasing disposal prices in excess of the Consumer Price Index in several of our markets. In fiscal year 2015, our average price per ton at our landfills was up 3.7% over the prior period as we increased tipping fees and improved the mix of materials.

We continue to work on strategies to source additional waste volumes to our landfills by increasing our geographic reach through the use of rail transportation and accessing new end-markets.

Driving additional profitability at collection operations

Over the last three years we have developed and implemented a number of programs designed to improve profitability and returns in the collection line-of-business, including: pricing yield analytics; new sales force incentives; route profitability analytics; on-route sales and marketing initiatives; a comprehensive fleet strategy; and selling or swapping underperforming routes or operations.

Our local collection teams have moved pricing from an annual process to a core process that is continually reviewed and adjusted throughout the year. Our division management and sales teams use our customer profitability analytics tool to calculate customer level profitability and increase pricing, where appropriate, to offset cost increases. We continue to yield success from our collection pricing programs, with commercial and residential collection price growth of 4.5% in fiscal year 2015.

We attempt to offset core inflationary pressures on an ongoing basis. In fiscal year 2015, we implemented the Sustainability Recycling Adjustment fee (“SRA fee”) to dynamically adjust residential and commercial collection pricing for monthly changes in recycling commodity prices. The SRA fee has been well received by our customers and is helping to offset significant commodity price headwinds.

During fiscal year 2014, we adjusted our sales force incentive compensation program to better support our efforts to drive responsibility to the local operating level. We introduced a uniform commission structure tracking and payment system to help our local teams administer customized commission structures for each sales representative, while maintaining a consistent system to track performance.

Collection routes are the basic building blocks of our solid waste business and we believe that it is imperative that we seek to ensure that each route is profitable and covers the cost of truck and container capital. In order to achieve this goal we developed and implemented a route profitability tool to help our operating teams analyze and improve their routing productivity and profitability. With the help of this tool, we increased the frequency of re-routing existing customers to improve efficiencies and take trucks off the road. In addition, we routinely evaluate on an account-by-account basis existing customer service levels, service types, equipment selection and truck type selection to seek to ensure that we are maximizing profitability and asset utilization. To further improve route density, we focus our marketing and sales efforts on existing routes.

5

To augment our operating efforts, we implemented a comprehensive fleet plan during transition period 2014 to define our fleet standards and specifically target truck replacements to maximize returns. We believe that this plan will help us to reduce our operating costs and improve our capital efficiency by reducing downtime and maintenance costs and improving service levels.

Differentiating business with resource solutions

To complement our traditional solid waste offerings, we have developed a set of resource solutions and invested in select assets that are intended to enhance our ability to support emerging customer and market needs. Our resource solutions strategy seeks to leverage our core competencies across our operating segments in materials processing, industrial recycling, clean energy, and organics service offerings in order to generate additional value from the waste stream for our customers. In fiscal year 2015, 25.4% of our revenues were generated by our Recycling, Customer Solutions and Organics businesses in the aggregate.

For nearly 40 years, we have been a leader in providing recycling services to our customers. We currently own or operate six material recovery facilities (“MRFs”) that use our Zero-Sort Recycling process, which we own or operate under long-term operating agreements. With Zero-Sort Recycling, customers can commingle all of their recyclables (paper, cardboard, plastics, metals, and glass) into a single, right-sized residential or commercial container. By making it easier for a customer to recycle, we have increased recycling participation and yields, thereby increasing volumes through our MRFs and enhancing asset utilization.

The average mix of recycling commodities generated by residential and commercial customers has historically sold at an average price that covered the cost of processing the materials, including an adequate return on the processing equipment, facilities, and rolling stock necessary to process the recyclables. Since 2011, recycling commodity prices have declined by approximately 60% to historically low levels as global demand for fiber and metal materials has significantly dropped and plastics pricing has declined with lower crude oil pricing. Roughly half of this decline in recycling commodity pricing has occurred since the beginning of fiscal year 2015.

At current recycling commodity pricing levels, we are not generating adequate revenue from the sale of these commodities to cover the cost of processing the materials or generating a positive return on our investment in recycling infrastructure. In order to continue to provide these necessary services to our residential, commercial, municipal, and industrial customers, we have readdressed our pricing model for these services by introducing the SRA fee in fiscal year 2015.

Our Customer Solutions business works with our industrial services, including multi-location customers, colleges and universities, municipalities, and industrial customers to develop customized comprehensive solid waste solutions. The focus of this group is to help these large scale organizations achieve waste reduction and diversion goals to meet their economic and environmental objectives. We believe that we differentiate our services from our competitors by providing a personalized set of resource solutions, which enables us to win new business, including traditional solid waste collection and disposal customers.

Our Organics business provides transportation, disposal and resource solutions to waste water treatment facilities across the northeast. In fiscal year 2015, our operations managed approximately 0.7 million tons of biosolids, with 0.2 million tons of this material internalized to our landfills and 0.4 million tons transformed into renewable products for fertilization and landscaping. In addition, our Organics group has been working to develop and/or partner with firms that have developed innovative approaches to deriving incremental value from source separated organics to comply with emerging waste regulations.

Improving our balance sheet and reducing business risk

We believe we are making excellent progress improving our balance sheet and reducing operational and financial risk. One of the key pillars of this initiative is our Enterprise Risk Management (“ERM”) program that helps us to more effectively identify and mitigate risk throughout all aspects of our business. This program has helped us to prioritize and focus resources on mitigating key risk areas.

During fiscal year 2015, our financial strategy was focused on maximizing cash flows to permanently retire indebtedness and refinancing near term debt maturities to reduce financing risks. We made significant progress in each area during fiscal year 2015 as we completed the refinancing of our senior revolving credit and letter of credit facility that was due March 2016 (“Senior Credit Facility”) with our new senior secured asset-based revolving credit and letter of credit facility due February 2020 (“ABL Facility”) in February 2015 and paid down our long-term debt by $15.8 million, decreasing our consolidated leverage ratio under our ABL Facility to 4.75 as of December 31, 2015 from 5.43 as of March 31, 2015. The ABL Facility allowed us to move out a key maturity date, while increasing our financial flexibility. We were able to take advantage of this additional flexibility during fiscal year 2015 by using excess cash flows to buy-back on the open market and permanently retire $14.7 million of our 7.75% senior subordinated notes due February 2019 (“2019 Notes”). The retirement of this portion of the 2019 Notes is expected to save us $1.1 million of annual cash interest expense.

6

Over the last three years we have made significant progress in simplifying our business structure, improving cash flows and reducing risk exposure by divesting and closing underperforming operations that did not enhance or complement our core operations. These actions included: (1) the divestiture of Maine Energy Recovery Company, LP (“Maine Energy”), a low margin, negative cash flow waste-to-energy operation, in fiscal year 2013; (2) the divestiture of KTI BioFuels, Inc. (“BioFuels”), a low margin, negative cash flow C&D processing facility, in fiscal year 2014; (3) the sale of our 50% equity interest in US GreenFiber LLC (“GreenFiber”), a negative cash flow cellulose insulation joint-venture, in fiscal year 2014; (4) the wind down of Casella-Altela Regional Environmental Services, LLC (“CARES”) through the disposal of the remaining assets of CARES in fiscal year 2015, in which we held a 51% membership interest; and (5) the sale of select low-margin collection routes in fiscal year 2015.

We believe that we are well-positioned for the future and remain strongly committed to a disciplined capital investment strategy, with excess cash flow expected to be primarily used to repay indebtedness. Further, we plan to continue our efforts to actively review our business portfolio for opportunities to improve financial performance by swapping or selling under-performing operations or making selective tuck-in acquisitions to improve route density or internalization.

Operational Overview

Our solid waste and recycling operations comprise a full range of non-hazardous solid waste, services, including collections, transfer stations, 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 eight 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, three of which are 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, are large-scale, high-volume facilities that process over 0.5 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 collection operations.

Landfills. We operate nine solid waste Subtitle D landfills and one landfill permitted to accept C&D materials. Revenues are received from municipalities and 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. The following table (in thousands) reflects the aggregate landfill capacity and airspace changes, in tons, for landfills we operated during fiscal year 2015, transition period 2014 and fiscal year 2014:

(1) We convert estimated remaining permitted capacity and estimated additional permittable capacity from cubic yards to tons generally by assuming a compaction factor equal to the historic average compaction factor applicable to the respective landfill over the last three fiscal years. 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.

(3) The change in new expansions pursued airspace capacity in fiscal year 2015 and fiscal year 2014 relates to the determination of additional permittable airspace at our Southbridge and NCES landfills in the Eastern region and our Chemung landfill in the Western region.

(4) The increase in remaining permitted airspace capacity in transition period 2014 was the result of a permit received at our NCES landfill.

(5) The variation in changes in airspace capacity associated with engineering estimates in fiscal year 2015, transition period 2014 and fiscal year 2014 is primarily the result of changes in compaction at our landfills and estimated airspace changes associated with design changes at certain of our landfills.

Eastern Region

NCES. The North Country Environmental Services landfill (“NCES”) is a Subtitle D landfill located in Bethlehem, New Hampshire that we purchased in 1994. NCES currently consists of approximately 54 acres of landfill area, is permitted to accept municipal solid waste, C&D material and certain pre-approved special waste and has no annual tonnage limitations.

Juniper Ridge. The Juniper Ridge landfill (“Juniper Ridge”) 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, 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 currently consists of approximately 179 acres of 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: 0.1 million tons of municipal solid waste per year through March 2018, 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. In January 2015, we entered into an agreement with a third-party to develop and construct a 4.8 mW/hr landfill gas-to-energy plant that is expected to be completed during the fiscal year ending December 31, 2017, which will be owned and operated by this third-party.

Southbridge. Southbridge is a Subtitle D landfill located in Southbridge, Massachusetts. In 2003, we acquired Southbridge Recycling and Disposal Park, Inc., which owns a recycling facility and has a contract with the Town of Southbridge, Massachusetts to operate Southbridge. Southbridge currently consists of approximately 95 acres of landfill area, and is permitted to accept 0.4 million tons of municipal solid waste, processed C&D residual material and certain pre-approved special waste annually. The Southbridge site houses a landfill gas-to-energy plant, which is owned and operated by us, that has the capacity to generate 1.6 mW/hr of energy.

Closure Projects. In 2005, we started closure operations at the Worcester, Massachusetts landfill (“Worcester”). These closure operations were completed in April 2014 when Worcester accepted its final tons of waste. We began final capping and closing Worcester in May 2014 and expect to be completed final capping and closing in the fiscal year ending December 31, 2016. Worcester is not included in the preceding table of landfill capacity.

8

Western Region

Waste USA. Waste USA, which is a Subtitle D landfill located in Coventry, Vermont that we purchased in 1995, is the only operating permitted Subtitle D landfill in the State of Vermont. Waste USA currently consists of approximately 148 acres of landfill area, and is permitted to accept 0.6 million tons of municipal solid waste, C&D material and certain pre-approved special waste annually. The Waste USA 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/hr of energy.

Clinton County. The Clinton County landfill (“Clinton”) is a Subtitle D landfill located in Schuyler Falls, New York. Clinton, which currently consists of approximately 170 acres of landfill area, is leased from Clinton County and is currently permitted to accept approximately 0.2 million tons of municipal solid waste, C&D material and certain pre-approved special waste annually. The Clinton 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/hr of energy.

Hyland. The Hyland landfill (“Hyland”) is a Subtitle D landfill located in Angelica, New York that we own, which began accepting waste in 1998. Hyland currently consists of approximately 121 acres of landfill area, and is permitted to accept 0.5 million tons of municipal solid waste, C&D material and certain pre-approved special waste annually. The Hyland 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/hr of energy. The Hyland landfill has nearby access to a rail siding and has the potential to attract waste volumes shipped via rail.

Ontario. The Ontario landfill (“Ontario”) is a Subtitle D landfill located in Seneca, New York. In 2003, we entered into a 25-year operation, management and lease agreement for Ontario with the Ontario County Board of Supervisors. Ontario currently consists of approximately 170 acres of landfill area, and is permitted to accept 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 Ontario for the acceptance of an estimated 13.6 million tons. The Ontario site houses a single stream 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/hr of energy.

Hakes. The Hakes C&D landfill (“Hakes”) is a C&D landfill located in Campbell, New York that we purchased in 1998. Hakes currently consists of approximately 81 acres of landfill area, and is permitted to accept 0.5 million tons of C&D material annually. Hakes has nearby access to a rail siding and is being marketed to attract waste volumes shipped via rail.

Chemung. The Chemung landfill (“Chemung”) 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 and certain other facilities with Chemung County. Chemung is strategically situated to accept long haul volume from both eastern and downstate New York markets. Chemung currently consists of approximately 126 acres of landfill area, which is sufficient to permit the additional airspace required for the term of the 25-year operation, management and lease agreement, and is permitted to accept 0.4 million tons of municipal solid waste and certain pre-approved special waste annually and eighty thousand tons of C&D material annually.

McKean. The McKean landfill (“McKean”) is a Subtitle D landfill located in Mount Jewett, Pennsylvania that we purchased in 2011 as part of a bankruptcy reorganization. McKean currently consists of approximately 256 acres of landfill area, and is permitted to accept one thousand tons of municipal solid waste, C&D material and certain pre-approved special waste daily. In March, 2014, the Commonwealth of Pennsylvania awarded a grant in the amount of $7.0 million to fund 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 the landfill is well situated to provide services to the oil and gas industry that explores natural gas in the Marcellus Shale of Pennsylvania in the form of disposal capacity for residual materials.

Closed Landfills

We also own and/or manage five unlined landfills and three lined landfills that are not currently in operation. We have closed and capped all of these landfills according to applicable environmental regulatory standards.

Operating Segments

We manage our solid waste operations, which include a full range of solid waste services, on a geographic basis through two regional operating segments, which we designate as the Eastern and Western regions. Our third operating segment is Recycling, which comprises our larger-scale recycling operations and our commodity brokerage operations. Organic services, ancillary operations, industrial services, discontinued operations and earnings from equity method investees, as applicable, are included in our “Other” segment. See Note 19, 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.

9

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 eight MRFs and one commodity brokerage operation comprising the Recycling segment, Recycling provides services to our six 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 a 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 29, 2016 except revenue information, which is for fiscal year 2015):

	Eastern Region		Western Region		Recycling		Other

See our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for our financial results for fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, and our financial position as of December 31, 2015, December 31, 2014 and April 30, 2014.

Eastern region

The Eastern region consists of wastesheds located in Maine, northern, central and southeastern New Hampshire and central and eastern Massachusetts. The Eastern region is vertically integrated, with transfer, landfill, processing and recycling assets serviced by our collection operations. In February 2013, we aligned management of NCES with the Eastern region. NCES had been historically aligned with the Western region. This move, combined with the permitting approvals at Southbridge, the opening of our transfer station in Westbrook, Maine, and the divestiture of Maine Energy, has helped reduce our overall reliance on waste-to-energy disposal capacity. Our December 2012 acquisition of Bestway Disposal Services and BBI Waste Services (“BBI”) strengthened both our collection and transfer network in New Hampshire and Maine by adding three collection operations and four, either owned or operated, transfer stations, and contributing additional internalized solid waste and recycling volumes to our disposal facilities. In August 2013, we divested of our BioFuels C&D processing facility in Lewiston, Maine, allowing us to focus on our higher margin core businesses.

We entered the Maine market in 1996 and have grown organically and through small acquisitions transacted in the late 1990’s and early 2000’s. In 2004, we obtained the right to operate Juniper Ridge under a 30-year agreement with the State of Maine. In December 2012, we acquired BBI, which gave us additional hauling and transfer capacity in southern Maine.

We entered the southern New Hampshire market in 1999 and the eastern Massachusetts market in 2000 and since have grown organically and through small acquisitions. In this market, we rely to a large extent on third-party disposal capacity, but NCES and other assets have provided additional opportunities to internalize volumes. We believe that we can continue to increase internalization rates in eastern Massachusetts as well with the increased capacity at Southbridge. In December 2013, we acquired a transfer station in Oxford, Massachusetts, allowing greater operational flexibility for our solid waste and recycling collection operations. The facility is permitted to accept 650 tons per day and provides a source of volume for Southbridge.

Western region

The Western region includes wastesheds located in Vermont, southwestern New Hampshire and eastern and upstate New York. The portion of eastern New York served by the Western region includes Clinton (operation of Clinton County), Franklin, Essex, Warren, Washington, Saratoga, Rennselaer and Albany counties.

The Western region also consists of wastesheds in upstate New York, which includes Ithaca, Elmira, Oneonta, Lowville, Potsdam, Geneva, Auburn, Dunkirk, Jamestown and Olean counties. We entered 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, Rochester, Buffalo and Albany.

We remain focused on increasing our vertical integration in the 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 eight MRFs that process and market recyclable materials that municipalities and commercial customers deliver under long-term contracts. Two of the eight MRFs are leased, three are owned, and three are operated by us under contracts with third-parties. In fiscal year 2015, the Recycling segment processed and/or marketed over 0.5 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 significant portion of the material provided to Recycling is delivered pursuant to six 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.

Our Recycling segment derives a significant portion of its revenues from the sale of recyclable materials. Since purchase and sale prices of recyclable materials, particularly newspaper, corrugated containers, plastics, ferrous and aluminum, can fluctuate based upon market conditions, we use long-term supply contracts with customers to reduce commodity risk. Under such contracts, we obtain a guaranteed minimum price for the recyclable materials along with a commitment to receive higher prices if the current market price rises. The contracts are generally with large domestic companies that use the recyclable materials in their manufacturing process, such as paper, packaging and consumer goods companies. In fiscal year 2015, 31.4% of the revenues from the sale of residential recyclable materials were derived from sales under long-term contracts which may include floor prices. 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, 2015, no such commodity hedges were in place.

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 industrial services (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 waste reduction and diversion goals to meet their economic and environmental objectives. We differentiate our services from our competitors by providing a customized set of comprehensive resource solutions, which enables us to win new business, including traditional solid waste collection and disposal customers.

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 an ownership interest

11

in AGreen Energy, LLC (“AGreen”) and BGreen Energy, LLC (“BGreen”), which we account for as cost method investments, that partners with other capital investors to build farm-based anaerobic digesters in the Northeast to generate electricity from farm and food waste streams.

Casella-Altela Regional Environmental Services, LLC

CARES is a joint venture that owned and operated a water and leachate treatment facility for the natural gas drilling industry in Pennsylvania. Our joint venture partner in CARES is Altela, Inc. (“Altela”). In fiscal year 2014, we determined that assets of the CARES water treatment facility were no longer operational or were not operating within product performance parameters. As a result, we initiated a plan to abandon and shut down the operations of CARES. It was determined that the carrying value of the assets of CARES was no longer recoverable and, as a result, the carrying value of the asset group was assessed for impairment and impaired. As a result, we recorded an impairment charge of $7.5 million in fiscal year 2014 to the asset group of CARES in the Western region.

We executed a purchase and sale agreement in fiscal year 2015 pursuant to which we and Altela agreed to sell certain assets of the CARES water treatment facility to a third-party. We sold these assets of CARES for purchase consideration of $3.5 million, resulting in a gain of $2.9 million in fiscal year 2015, 49% of which was attributable to Altela, the noncontrolling interest holder. As of December 31, 2015, we continued to pursue the dissolution of CARES in accordance with the CARES agreement.

In connection with this transaction, we also sold certain of our equipment and real estate to the same third-party for total consideration of $1.1 million, resulting in a gain of $0.9 million in fiscal year 2015. As of December 31, 2015, our ownership interest in CARES is 51%. In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810-10-15, we consolidate the assets, liabilities, noncontrolling interest and results of operations of CARES into our consolidated financial statements due to our controlling financial interest in the joint venture.

Equity Method Investments

In the fiscal year 2014, we sold our 50% membership interest in GreenFiber and purchased the remaining 50% membership of Tompkins County Recycling LLC (“Tompkins”), both of which were previously accounted for using the equity method of accounting.

GreenFiber. In fiscal year 2014, we and Louisiana Pacific Corporation (“LP”) executed a purchase and sale agreement with a limited liability company formed by Tenex Capital Partners, L.P., pursuant to which we and LP agreed to sell our membership interests in GreenFiber for total cash consideration of $18.0 million plus an expected working capital true-up less any indebtedness and other unpaid transaction costs of GreenFiber as of the closing date. The transaction was completed for $19.2 million in gross cash proceeds, including a $1.2 million working capital adjustment. After netting indebtedness of GreenFiber and transaction costs, our 50% of the net cash proceeds amounted to $3.4 million. After considering the $0.6 million impact of our unrealized losses relating to derivative instruments in accumulated other comprehensive income on our investment in GreenFiber, we recorded a gain on sale of equity method investment of $0.6 million in fiscal year 2014.

Tompkins. Also in fiscal year 2014, we purchased the remaining 50% membership interest of Tompkins for total cash consideration of $0.4 million. The acquisition-date fair value of our investment in Tompkins, which was determined using the cost approach based on an assessment of the price to purchase the acquired assets of Tompkins prior to the acquisition date, was $0.3 million. We recognized a gain of $0.1 million in fiscal year 2014 through loss from equity method investments due to the remeasurement. As a result of the purchase, we began including the accounts of Tompkins in our consolidated financial statements.

Competition

The 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.

The larger urban markets in which we compete are served by one or more of the large national solid waste companies, including Waste Management, Inc., Republic Services, Inc. and Waste Connections, Inc., that 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, and with certain municipalities, counties and districts that operate their own solid waste collection and disposal facilities. Public sector facilities may have certain advantages over us due to the availability of user fees, charges or tax revenues and tax-exempt financing.

12

Marketing and Sales

We 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 also focused on growing our share of business with municipal, institutional 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 attracting new commercial and residential customers directly on-route in order to enhance profitability. Marketing campaigns are integrated with divisional management, sales personnel and the centralized customer care center.

Employees

As of January 29, 2016, we employed approximately 1,900 people, including approximately 400 professionals or managers, sales, clerical, information systems or other administrative employees and approximately 1,500 employees involved in collection, transfer, disposal, recycling or other operations. Approximately 80 of our employees are covered by collective bargaining agreements. We believe relations with our employees are good.

Risk Management, Insurance and Performance or Surety Bonds

We 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. We also maintain a worker safety program, which focuses on safe practices in the workplace. Operating practices at all of our operations are intended to reduce the possibility of environmental contamination, enforcement actions and litigation.

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. 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.

We self-insure for automobile and workers’ compensation coverage with reinsurance coverage limiting our maximum exposure. Our maximum exposure in fiscal year 2015 under the workers’ compensation plan was $1.0 million per individual event. Our maximum exposure in fiscal year 2015 under the automobile plan was $1.2 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.

13

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 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 also 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 newspaper advertising and retail activity during the holiday season.

Regulation

Introduction

We are subject to extensive and evolving federal, state and local environmental laws and regulations which have become increasingly stringent in recent years. 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 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 actions. 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.

14

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.

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, 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 a treatment facility that is owned by a local municipality. 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.

15

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. In addition, 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. In addition, 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. 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 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 June 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 PSD / Title V regulation. In July 2011, however, the EPA promulgated a rule that, broadly, deferred for three years the applicability of those regulations with regard to sources emitting carbon dioxide from biomass-fired and other “biogenic” sources. In June 2014, the U.S. Supreme Court issued a decision partially invalidating EPA’s Tailoring Rule. We do not know whether or when the EPA will put those regulations in place following the Supreme Court decision, or what obligations such regulations will impose on our operations.

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 contemplating air pollution control regulations 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 also is considering 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 increasing 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 four landfill gas-to-energy facilities are self- certified as “qualifying facilities”.

State and Local Regulations

Each 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. These 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.

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. Further, 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. In sum, 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, 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 bill became effective July 1, 2012, with phased deadlines for compliance beginning 2014 through 2020. Vermont also passed a bill 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 is considering revisions to its regulations governing solid waste management, 6 NYCRR Part 360.

Although there is no federal law governing extended producer responsibility (“EPR”) regulations; many states have implemented 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.

ITEM 1A. 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.

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. Some of 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.

19

As is generally the case in our industry, some municipal contracts are 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 and, in some cases, utilize government subsidies.

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 increasingly recognizing the value of the waste stream as a renewable resource, and accordingly, new alternatives to landfilling are being developed that seek to maximize the renewable energy and other resource benefits of solid waste. These alternatives may well affect the demand for landfill airspace, which could then 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 utilization of landfill airspace. Reduced tipping fees can also 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 regulations, and we incur substantial costs to comply with such regulations. Failure to comply with environmental or other regulations, as well as enforcement actions and litigation arising from an actual or perceived breach of such 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, including those relating to transportation, recycling, treatment, storage and disposal of wastes, discharges of pollutants to air and water, and the remediation of contaminated soil, surface water and groundwater. 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 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 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. 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. Environmental and land use laws 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. We have historically grown through acquisitions, may make additional acquisitions from time to time 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, including ones that may exist only because of the past operations of an acquired business, 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 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 legally responsible for addressing it. Some of the legal sanctions to which we could become subject could cause the suspension or revocation of a needed 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, 2015, we had recorded $5.2 million in environmental remediation liabilities 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. There can be no assurance that the cost of such cleanup or that our share of that cost will not exceed our estimates.

20

In addition to the costs of complying with environmental laws and regulations, we incur costs defending against environmental litigation brought by government agencies and private parties. We are, and may be in the future, a defendant in lawsuits brought by parties alleging environmental damage, personal injury, and/or property damage, or seeking to overturn or prevent the issuance of an operating permit or authorization, all of which may result in us incurring significant liabilities. In October 2015, our Southbridge Recycling and Disposal Park 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 Southbridge that indicated the presence of contaminants above the levels triggering notice and response obligations under regulations promulgated by MADEP regulations. We are implementing a plan to analyze and better understand the groundwater near the landfill, is carrying out an Immediate Response Action pursuant to state law, and is investigating for the purpose 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 Southbridge, we will evaluate what liability we may have for the related costs and liabilities. In February 2016, we received notice from a law firm purporting to represent a number of residents proximate to Southbridge of its intent to file suit against us. The existence of these contaminants and any related lawsuit or other action could delay our ongoing permitting activities at Southbridge and result in costs and liabilities, each of which could have a material impact on our results of operations and financial condition.

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. Localities where we operate generally seek to regulate some or all landfill and transfer station operations, including siting and expansion of operations. The laws 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. 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.

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.

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. Also, 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 also 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.

See also Item 1, “Business”, Item 3, “Legal Proceedings” and Note 10, Commitments and Contingencies to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K.

Our results of operations could continue to be affected by fluctuating commodity prices or market requirements for recyclable materials.

Our results of operations have been and may continue to be affected by changing 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 market for recyclable materials was affected by unprecedented price decreases in October 2008, resulting in a severe impact on our results of operations. Currently, the commodity markets continues 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. From an export standpoint, China’s slowing economic environment and increasing ability to create its own domestic recyclables has changed the landscape of the recycling markets, which has decreased the demand for U.S fiber. On the domestic front, within the Northeast, there continues to be very little demand for the newspaper grade leading us to turn to the export market throughout all material recovery facilities within our footprint. The plastic grades continue to decline with lower oil prices. Although we may seek to limit our exposure to fluctuating commodity prices through the use of hedging agreements, floor price contracts and long-term supply contracts with customers and have sought to mitigate commodity price fluctuations by reducing the prices we pay for purchased materials or increasing tip fees at our facilities, these fluctuations have in the past contributed, and may continue to contribute, to significant variability in our period-to-period results of operations. Although, we have the SRA fee to help offset increases in the cost of commodities arising from price volatility, we cannot provide assurance that we can pass this fee on to our customers where their contracts and competition conditions permit.

21

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.

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, 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 which would have an adverse effect on our business.

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 2015, we used approximately 5.0 million gallons of diesel fuel in our solid waste operations. Although, we have a “fuel and oil recovery fee” program, based on a fuel index, to help offset increases in the cost of fuel, oil and lubricants arising from price volatility, we cannot provide assurance that we can pass this fee on to our customers where their contracts and competition conditions permit.

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 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, 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. Any future difficulty in obtaining insurance could also impair our ability to secure future contracts conditioned upon having adequate insurance coverage.

22

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.

See Note 3, Summary of Significant Accounting Policies and Note 16, Divestiture Transactions and Discontinued Operations to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for disclosure related to asset impairments recognized during the disclosed reporting periods.

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.

Our Recycling business experiences increased volumes of fiber in November and December due to increased newspaper advertising and retail activity during the holiday season.

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.

We may, in the future, attempt to divest or sell certain parts or components of our business to third-parties, which may result in lower than expected proceeds or losses or the inability to identify potential purchasers.

From time to time in the future, we may sell or divest certain other components of our business. These divestitures may be undertaken for a number of reasons, including to generate proceeds to pay down debt, or as a result of a determination that the specified asset will provide inadequate returns to us, that the asset no longer serves a strategic purpose in connection with our business or that the asset may be more valuable to a third-party. The timing of such sales or divestures may not be entirely within our control. For example, we may need to quickly divest assets to satisfy immediate cash requirements, or we may be forced to sell certain assets prior to canvassing the market or at a time when market conditions for valuations or for financing for buyers are unfavorable. Such sales or

divestitures may result in proceeds to us in an amount less than we expect or less than our assessment of the value of those assets. We also may not be able to identify buyers for certain of our assets, particularly given the difficulty that potential acquirers may face in obtaining financing, or we may face opposition from municipalities or communities to a disposition or the proposed buyer. Any sale of our assets could result in a loss on divestiture. Any of the foregoing would have an adverse effect on our business and results of operations.

We may engage in acquisitions in the future with the goal of complementing or expanding our business, including developing additional disposal capacity. 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.

We have in the past, and we may in the future, make acquisitions in order to acquire or develop additional disposal capacity. 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. 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, including as a result of the limitations imposed by our debt obligations. Furthermore, we may be unable to obtain the necessary regulatory approval 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 properties or facilities that we acquire may be subject to unknown liabilities, such as undisclosed environmental contamination, for which we would have no recourse, or only limited recourse, to the former owners of such 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.

Efforts by labor unions to organize our employees could divert management attention and increase our operating expenses.

Labor unions regularly make attempts to organize our employees, and these efforts will likely continue in the future. 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 29, 2016, approximately 4.4% of our employees were represented by unions.

Actions of activist stockholders against us could be disruptive and potentially costly and the possibility that activist stockholders may seek changes that contest, or conflict with, our strategic direction could cause uncertainty about the strategic direction of our business.

Activist stockholders may from time to time attempt to effect changes in our strategic direction and, in furtherance thereof, may seek changes in how we are governed. While our Board of Directors and management team strive to maintain constructive, ongoing communications with all of our stockholders, including activist stockholders, and welcomes their views and opinions with the goal of working together constructively to enhance value for all stockholders, activist campaigns that contest, or conflict with, our strategic direction could have an adverse effect on us because:

• responding to proxy contests and other actions by activist stockholders can disrupt our operations, be costly and time-consuming, and divert the attention of our Board of Directors and senior management from the pursuit of business strategies, which could adversely affect our results of operations and financial condition;

• perceived uncertainties as to our future direction as a result of changes to the composition of our Board of Directors may lead to the perception of a change in the direction of the business, instability or lack of continuity which may be exploited by our competitors, cause concern to our current or potential customers, may result in the loss of potential business opportunities and make it more difficult to attract and retain qualified personnel and business partners;

• these types of actions could cause significant fluctuations in our stock price based on temporary or speculative market perceptions or other factors that do not necessarily reflect the underlying fundamentals and prospects of our business; and

• If individuals are elected to our Board of Directors with a specific agenda, it may adversely affect our ability to effectively implement our business strategy and create additional value for our stockholders.

24

In connection with our 2015 Annual Meeting, an activist investor initially proposed its own slate of director candidates. That activist investor ultimately withdrew its slate of director candidates prior to the 2015 Annual Meeting and all of our director nominees were elected at the 2015 Annual Meeting. That activist investor continues to have a Schedule 13D filed with respect to us and it remains a possibility that such activist investor may still, from time to time, attempt to effect changes in our strategic direction and, in furtherance thereof, may seek changes in how we are governed.

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, 2015, we had approximately $525.0 million of outstanding principal indebtedness (excluding approximately $26.9 million of outstanding letters of credit issued under the ABL Facility) and an additional $64.1 million of unused commitments under the ABL Facility, which consists of a revolving credit facility with loans thereunder being available up to an aggregate principal amount of $190.0 million, subject to availability under the borrowing base formula as defined in the ABL Facility agreement. 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;

• places us at a competitive disadvantage compared with some of our competitors that may have less debt and better access to capital resources; and

• limits our ability to obtain additional financing required to fund working capital and capital expenditures and for other general corporate purposes.

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.

To service our indebtedness, we will require a significant amount of cash. However, our ability to generate cash depends on many factors beyond our control.

Our ability to make payments on, and to refinance, our indebtedness and to fund planned capital expenditures will depend on our ability to generate cash in the future which, in turn, is subject to general economic, financial, competitive, regulatory and other factors, many of which are beyond our control.

Our business may not generate sufficient cash flows from operations and we may not have available to us future borrowings in an amount sufficient to enable us to pay our indebtedness or to fund our other liquidity needs. In these circumstances, we may need to refinance all or a portion of our indebtedness on or before maturity. We may not be able to refinance any of our indebtedness on commercially reasonable terms, or at all. Without this financing, we could be forced to sell assets or secure additional financing to make up for any shortfall in our payment obligations under unfavorable circumstances. However, we may not be able to secure additional financing on terms favorable to us or at all and, in addition, the terms of our debt agreements limit our ability to sell assets and also restrict the use of proceeds from such a sale. Moreover, substantially all of our assets have been pledged to secure repayment of our indebtedness under the ABL Facility. In addition, we may not be able to sell assets quickly enough or for amounts sufficient to enable it to meet our obligations.

The agreements governing our various debt obligations impose restrictions on our business and adversely affect our ability to undertake certain corporate actions.

The agreements governing our various debt obligations include covenants imposing significant restrictions on our business. These restrictions may affect our ability to operate our business and may limit our ability to take advantage of potential business opportunities as they arise. These covenants place restrictions on our ability to, among other things:

• incur additional debt;

25

• create liens;

• make certain investments;

• enter into certain transactions with affiliates;

• declare or pay dividends, redeem stock or make other distributions to stockholders; and

• consolidate, merge or transfer or sell assets.

The ABL Facility requires us to meet a number of financial ratios and covenants and restricts our ability to make certain capital expenditures.

Our ability to comply with our debt agreements 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. Specifically, the ABL Facility requires us to maintain a certain minimum consolidated EBITDA measured at the end of each fiscal quarter. Additionally, during certain periods based upon availability of revolver loans being less than an agreed upon amount, the ABL Facility requires us to meet financial ratios, including, without limitation:

• a minimum consolidated fixed charge coverage ratio; and

• a maximum consolidated first lien funded debt 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 ABL 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 ABL 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.

Our ability to make acquisitions may be adversely impacted by our outstanding indebtedness and by the price of our stock.

Our ability to make future business acquisitions, particularly those that would be financed solely or in part through cash from operations, will be curtailed due to our obligations to make payments of principal and interest on our outstanding indebtedness. We may not have sufficient capital resources, now or in the future, and may be unable to raise sufficient additional capital resources on terms satisfactory to us, if at all, in order to meet our capital requirements for such acquisitions. In addition, the terms of our indebtedness include covenants that directly restrict, or have the effect of restricting, our ability to make certain acquisitions while this indebtedness remains outstanding. To the extent that the amount of our outstanding indebtedness continues to have a negative impact on our stock price, using our Class A common stock as consideration will be less attractive for potential acquisition candidates. In the past, the trading price of our Class A common stock on the NASDAQ Global Select Market has limited our willingness to use our equity as consideration and the willingness of sellers to accept our shares and as a result has limited, and could continue to limit, the size and scope of our acquisition program. If we are unable to pursue acquisitions that would enhance our business or operations, the potential growth of our business and revenues may be adversely affected.

Risks Related to Our Common Stock

Our Class B common stock is entitled to ten votes per share and is held exclusively by John W. Casella and Douglas R. Casella.

The holders of our Class B common stock are entitled to ten votes per share and the holders of our Class A common stock are entitled to one vote per share. As of December 31, 2015, an aggregate of 988,200 shares of our Class B common stock, representing 9,882,000 votes, were outstanding, all of which were 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. Based on the number of shares of common stock outstanding on January 29, 2016, the shares of our Class A common stock and Class B common stock beneficially owned by John W. Casella and Douglas R. Casella represent approximately 22.1% of the aggregate voting power of our stockholders. Consequently, John W. Casella and Douglas R. Casella may be able to substantially influence certain matters submitted to stockholders for approval, including proposed amendments to our certificate of incorporation and bylaws requiring an affirmative vote of shares representing at least 75% of the votes that all holders of our Class A common stock and our Class B common stock would be entitled to cast.

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 29, 2016, we operated nine subtitle D landfills, four of which we own and five of which we lease; one landfill permitted to accept C&D materials that we own; 44 transfer stations, 24 of which we own, nine of which we lease and 11 of which we operate under a contract; 34 solid waste collection facilities, 20 of which we own and 14 of which we lease; 18 recycling processing facilities, nine of which we own, six of which we lease and three of which we operate under a contract; four landfill gas-to-energy facilities that we own; and 20 corporate office and other administrative facilities, three of which we own and 17 of which we lease (See Item 1, “Business” of this Annual Report on Form 10-K for property information by operating segment). 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 alleging environmental damage or violations of the permits and licenses pursuant to which we operate. In addition, we have been 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 450-20, 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.

Expera Old Town, LLC v. Casella Waste Systems, Inc.

On or about November 6, 2015, Expera Old Town, LLC (“Expera”) filed a lawsuit against us in Maine Superior Court, seeking damages for breach of contract and unjust enrichment, and an action for declaratory judgment (the “Lawsuit”). Expera was a successor-in-interest to a contract between us and Old Town Fuel and Fiber (“OTFF”), the former owner of a pulp manufacturing facility (“Facility”) located in Old Town, Maine (the “Contract”). Expera purchased the Facility during the pendency of the bankruptcy of OTFF. Since the filing of the Lawsuit, Expera has sold the Facility and related assets, to MFGR LLC (“MFGR”). MFGR continues to allege that we have the obligation to provide a specialized type of wood fuel to the Facility or, alternatively, that we owe a “Fuel Replacement Fee” of up to $2.0 million a year (subject to the possibility of certain credits against such payments). The Contract expires in 2036. We believe we have meritorious defenses to each of the claims in the Lawsuit, are vigorously contesting these allegations, and have filed a counter claim for funds owed to us by MFGR or Expera.

On or about February 10, 2016, we reached an agreement in principle with MFGR to dismiss this suit with prejudice, and to resolve all outstanding claims of any nature including future claims which could arise under the Contract. The Parties are endeavoring in good faith to enter into a settlement agreement (“SA”) and ancillary agreements. Pursuant to the pending SA, we will pay MFGR $1.3 million upon execution of the SA, and $0.4 million a year for five years following execution of the SA. Accordingly, taking into account the net present value of the settlement payments, we have recorded a reserve of $2.6 million as of December 31, 2015. This includes a contract settlement charge of $1.9 million and $0.7 million of operating expenses recorded in fiscal year 2015. We also reserved $0.1 million as of December 31, 2015 for legal costs associated with the Lawsuit and SA.

27

We will also enter into a new leachate disposal agreement at market prices with MFGR for the treatment of leachate from Juniper Ridge managed by us for the State of Maine located in Old Town, Maine, and MFGR will enter into a waste disposal agreement at market prices with us for the disposal at Juniper Ridge of waste materials produced in the demolition or re-purposing of the Facility.

Greenwood Street Landfill, Worcester, Massachusetts

On July 2, 2014, we received a draft Administrative Consent Order with Penalty and Notice of Noncompliance (“Draft Order”) from MADEP alleging that a subsidiary, NEWS of Worcester, LLC, had completed substantive closure of a portion of the Greenwood Street Landfill in Worcester, Massachusetts in 2010, at an elevation exceeding the applicable permit condition. While we neither admitted nor denied the allegations in the Draft Order, a final Administrative Consent Order with Penalty and Notice of Noncompliance was executed on March 20, 2015 (“Final Order”), and we agreed to pay a civil administrative penalty in a total amount of approximately $0.2 million. MADEP agreed that approximately $0.1 million of that amount could be paid as a Supplemental Environmental Project (“SEP”) for work being done by the Massachusetts Audubon Society at the Broad Meadow Brook Conservation Center & Wildlife Sanctuary in Worcester, Massachusetts. This SEP has been paid in full.

Environmental Remediation Liability

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 matter represents our outstanding material claim.

Potsdam Environmental Remediation Liability

On December 20, 2000, the State of New York Department of Environmental Conservation (“DEC”) issued an Order on Consent (“Order”) which named Waste-Stream, Inc. (“WSI”), our subsidiary, General Motors Corporation (“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 15% participant share. It is unlikely that any significant expenditures relating to onsite remediation will be incurred until the fiscal year ending December 31, 2017. WSI is jointly and severally liable with NiMo, Alcoa and Reynolds for the total cost to remediate.

28

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 1.8%. The changes to the environmental remediation liability associated with the Potsdam environmental remediation liability are as follows:

	Fiscal Year Ended December 31, 2015	Eight Months Ended December 31, 2014
Beginning balance	$                    5.1	$	5.3

As of January 29, 2016 there were approximately 500 holders of record of our Class A common stock and two holders of record of our Class B common stock.

For purposes of calculating the aggregate market value of the shares of common stock held by non-affiliates, as shown on the cover page of this Annual Report on Form 10-K, we have assumed that all the outstanding shares of Class A common stock were held by non-affiliates except for the shares beneficially held by directors and executive officers and funds represented by them.

Dividends

No dividends have ever been declared or paid on our common stock and we do not anticipate paying any cash dividends on our common stock in the foreseeable future. Our ABL Facility and indentures restrict or condition the payment of dividends on common stock. The information required by Item 201(d) of Regulation S-K is included in Part III of this Annual Report on Form 10-K.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The 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.

Change in Fiscal Year

In June 2014, we elected to change our fiscal year-end from April 30^th to December 31^st. The change in fiscal year became effective for our fiscal year beginning January 1, 2015 and ending December 31, 2015. As a result of this change, financial results for fiscal year 2015 are compared to the unaudited financial results for calendar year 2014, and the financial results for transition period 2014 are compared to the unaudited financial results for eight months 2013. When financial results for fiscal year 2014 are compared to financial results for fiscal year 2013, the results are presented on the basis of our previous fiscal year-end on a twelve month basis.

Company Overview

Founded in 1975 with a single truck, Casella Waste Systems, Inc., its wholly-owned subsidiaries and certain partially owned entities over which it has a controlling financial interest, 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 manage our solid waste operations on a geographic basis through two regional operating segments, the Eastern and Western regions, each of which provides a full range of solid waste services, and our larger-scale recycling and commodity brokerage operations through our Recycling segment. Organics services, ancillary operations, industrial services, discontinued operations, and earnings from equity method investees, as applicable, are included in our Other segment.

33

As of January 29, 2016, we owned and/or operated 34 solid waste collection operations, 44 transfer stations, 18 recycling facilities, nine Subtitle D landfills, four landfill gas-to-energy facilities and one landfill permitted to accept C&D materials.

Acquisitions and Divestitures

Acquisitions

We have a dedicated 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 considerable competition for acquisition targets, particularly the larger and more meaningful targets, due to among other things, our limited access to and weighted average cost of capital, but we believe that our strong relationships and reputation in New England and the upstate New York area help to offset these factors.

There were no acquisitions in fiscal year 2015.

During transition period 2014, we acquired one solid waste hauling operation in each of the Eastern and Western regions for total consideration of $0.4 million, including $0.3 million in cash and $0.1 million in holdbacks to the sellers.

We acquired various businesses during fiscal year 2014, including several solid waste hauling operations, a transfer station, a MRF and an industrial service management business (included in the Other segment) for total consideration of $10.1 million, including $7.9 million in cash, $1.7 million in contingent consideration and holdbacks to the sellers and $0.5 million of other non-cash considerations. We recovered $0.2 million of the purchase price holdback amount we had previously paid and were relieved of any potential contingent consideration obligation associated with the acquisition of an industrial service management business earlier in fiscal year 2014. As a result, we recorded a $1.1 million gain on settlement of acquisition related contingent consideration in fiscal year 2014.

We acquired various solid waste hauling operations during fiscal year 2013, including the acquisition of all of the outstanding capital stock of BBI in the Eastern region, for total consideration of $27.9 million in cash and approximately 0.6 million shares of our Class A common stock, valued at an aggregate of $2.7 million. We recorded an additional $5.1 million to goodwill for the increased deferred tax liability related to the BBI acquisition based on the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and such amount recognized for income tax purposes. See Note 14, Income Taxes to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for further discussion. The acquisition of BBI, a provider of solid waste collection, transfer and liquid waste services in New Hampshire and Maine, provided us the opportunity to internalize additional waste and recyclables and to consolidate operations, routes and transportation within the Eastern region.

Divestitures

From 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.

Sale of Business. In fiscal year 2015, we divested a business, which included the sale of certain assets associated with various waste collection routes in the Western region, for total consideration of $0.9 million, resulting in a gain of $0.6 million.

CARES and Related Transaction. We executed a purchase and sale agreement in fiscal year 2015 pursuant to which we and Altela agreed to sell certain assets of the CARES water treatment facility to a third-party. We sold these assets of CARES for purchase consideration of $3.5 million, resulting in a gain of $2.9 million in fiscal year 2015, 49% of which was attributable to Altela, the noncontrolling interest holder. As of December 31, 2015, we continued to pursue the dissolution of CARES in accordance with the CARES agreement.

34

In connection with this transaction, we also sold certain of our equipment and real estate to the same unrelated third-party for total consideration of $1.1 million, resulting in a gain of $0.9 million in fiscal year 2015.

There were no divestitures in transition period 2014.

GreenFiber. In fiscal year 2014, we and LP executed a purchase and sale agreement with a limited liability company formed by Tenex Capital Partners, L.P., pursuant to which we and LP agreed to sell our membership interests in GreenFiber for total cash consideration of $18.0 million plus an expected working capital true-up less any indebtedness and other unpaid transaction costs of GreenFiber as of the closing date. The transaction was completed for $19.2 million in gross cash proceeds, including a $1.2 million working capital adjustment. After netting indebtedness of GreenFiber and transaction costs, our 50% of the net cash proceeds amounted to $3.4 million. After considering the $0.6 million impact of our unrealized losses relating to derivative instruments in accumulated other comprehensive loss on our investment in GreenFiber, we recorded a gain on sale of equity method investment of $0.6 million in fiscal year 2014. We had previously accounted for our 50% membership interest in GreenFiber using the equity method of accounting.

Maine Energy. In fiscal year 2013, we executed a purchase and sale agreement with the City of Biddeford, Maine, pursuant to which we agreed to sell the real property of Maine Energy to the City of Biddeford. We agreed to sell Maine Energy for an undiscounted purchase consideration of $6.7 million, which is being paid to us in installments over twenty-one years. Later in fiscal year 2013, we closed the transaction, ceased operations of the Maine Energy facility, and initiated the decommissioning, demolition and site remediation process in accordance with the provisions of the agreement. In fiscal year 2015, we completed the demolition process and site remediation under the auspices and in accordance with work plans approved by the Maine Department of Environmental Protection and the EPA. Based on the total incurred costs to fulfill our obligation under the agreement, we reversed a reserve of $1.1 million of excess costs to complete the divestiture in fiscal year 2015.

BioFuels. In fiscal year 2013, we initiated a plan to dispose of BioFuels and as a result, the assets associated with BioFuels were classified as held-for-sale and the results of operations were recorded as income from discontinued operations. Assets of the disposal group previously classified as held-for-sale, and subsequently included in discontinued operations, included certain inventory along with plant and equipment. In fiscal year 2014, we executed a purchase and sale agreement with ReEnergy Lewiston LLC (“ReEnergy”), pursuant to which we agreed to sell certain assets of BioFuels, which was located in our Eastern region, to ReEnergy. We agreed to sell the BioFuels assets for undiscounted purchase consideration of $2.0 million, which was to be paid to us in equal quarterly installments over five years commencing November 1, 2013, subject to the terms of the purchase and sale agreement. The related note receivable was paid in full by ReEnergy in transition period 2014. We recognized a $0.4 million loss on disposal of discontinued operations in fiscal year 2014 associated with the disposition. As a part of the divestiture, we agreed to complete certain site improvements at Biofuels, which were completed in transition period 2014. As a result, we recorded a $0.6 million gain in transition period 2014 associated with reversing the excess remaining reserves not needed to complete the site improvements.

Revenues

We manage our solid waste operations, which include a full range of solid waste services, on a geographic basis through two regional operating segments, which we designate as the Eastern and Western regions. Revenues in our Eastern and Western regions consist primarily of fees charged to customers for solid waste collection and disposal, 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. In addition, revenues from our Recycling segment consist of revenues derived from municipalities and customers in the form of processing fees, tipping fees and commodity sales. Organics services, ancillary operations, major account and industrial services, discontinued operations, and earnings from equity method investees, as applicable, are included in our Other segment. Our revenues are shown net of inter-company eliminations.

Operating Expenses

The following table summarizes our cost of operations, general and administration expenses and depreciation and amortization expenses as a percentage of revenues for the following periods:

	Twelve Months Ended December 31,				Eight Months Ended December 31,				Fiscal Year Ended April 30,
	2015		2014		2014		2013		2014		2013
			Unaudited				Unaudited
Cost of operations		70.0%		71.7%		70.2%		69.4%		71.3%		70.9%
General and administration		13.3%		12.7%		12.4%		12.0%		12.4%		12.8%
Depreciation and amortization		11.5%		11.6%		11.3%		11.9%		12.1%		12.4%

Cost of Operations

Cost of operations includes labor costs, tipping fees paid to third-party disposal facilities, fuel costs, maintenance and repair costs of vehicles and equipment, workers’ compensation and vehicle insurance costs, the cost of purchasing materials to be recycled, third-party transportation costs, district and state taxes, host community fees and royalties. Cost of operations also includes accretion expense related to final capping, closure and post-closure obligations, leachate treatment and disposal costs and depletion of landfill operating lease obligations.

Cost of Operations – Fiscal Year 2015 compared to Unaudited Calendar Year 2014

Our cost of operations increased $5.4 million, decreasing 1.7% as a percentage of revenues, for fiscal year 2015 when compared to calendar year 2014.

The period-to-period changes in cost of operations can be primarily attributed to the following:

• Direct operational costs increased $4.2 million due to: higher equipment rental costs; higher operating costs (including grounds maintenance and gas control) at certain of our landfills; and higher leachate disposal costs at certain of our landfills due to unusually high rainfall earlier in the year. These cost increases were partially offset by lower gas treatment costs at Juniper Ridge and lower depletion of landfill operating lease obligations at Southbridge and certain of our Western region landfills.

• Maintenance and repair costs increased $3.9 million due to: higher fleet maintenance costs in the Eastern and Western regions and higher facility maintenance costs associated with our Recycling segment and our Eastern region landfills.

41

• Labor and related benefit costs increased $3.3 million due to: additional labor costs due to higher collection and transfer station volumes in the Eastern region associated with new municipal contracts and organic customer growth; processing of higher commodity volumes due to new contracts and facilities in the Recycling segment; and lower productivity as a result of prolonged inclement winter weather into the early spring of 2015.

• Third-party direct costs increased $0.2 million due to: higher collection and disposal volumes from organic customer growth, including various new contracts, and various acquisitions; and higher commodity volumes in the Recycling segment. These cost increases were offset by lower purchased material costs associated with declining commodity prices within the Recycling segment; lower purchased material costs in our Customer Solutions business; and the expiration of an out-of-market put-or-pay waste disposal contract in the Eastern region.

• Fuel costs decreased $6.0 million due to lower diesel fuel prices in the marketplace. The favorable impact associated with lower diesel fuel prices was more than offset by interrelated higher recycling tipping fees, lower fuel and oil recovery fees, lower recycling commodity pricing and lower energy pricing revenues during fiscal year 2015.

Cost of Operations – Transition Period 2014 compared to Unaudited Eight Month Period 2013

Our cost of operations increased $22.6 million, or 0.8% as a percentage of revenues, for transition period 2014 when compared to eight month period 2013.

The period-to-period change in cost of operations can be primarily attributed to the following:

• Third-party direct costs increased $11.8 million due to: organic and acquisition growth in our Customer Solutions business, which has a higher inherent direct cost structure; higher collection and disposal volumes from organic customer growth and the acquisition of a transfer station in the Eastern region; higher volumes in our Organics business; and higher disposal volumes associated with four new transfer station contracts and the acquisition of various hauling operations in the Western region.

• Maintenance and repair costs increased $4.8 million due to: higher facility maintenance costs associated with our Recycling segment, our hauling operations, certain landfills in our Western and Eastern regions, and the acquisition of a transfer station in the Eastern region; and higher fleet repair and maintenance costs associated with hauling operations.

• Labor and related benefit costs increased $4.9 million due to: increased overall healthcare costs and increased labor costs associated with higher collection and transfer station volumes in the Eastern region and new contracts and facilities in the Recycling segment.

• Direct operational costs increased $1.5 million due to: higher depletion of landfill operating lease obligations associated with increased volumes received at our landfills; an increase in host community fees and royalties; higher equipment rental costs associated with an increase in fleet and landfill equipment rentals; an increase in gas treatment costs at Juniper Ridge; and a lower gain on sale of fixed assets in transition period 2014.

• Fuel costs decreased $0.6 million primarily due to lower diesel fuel prices in the marketplace.

Cost of Operations – Fiscal Year 2014 compared to Fiscal Year 2013

Our cost of operations increased $31.6 million, or 0.4% as a percentage of revenues, for fiscal years 2014 when compared to fiscal year 2013.

The period-to-period change in cost of operations can be primarily attributed to the following:

• Third-party direct costs increased $17.4 million due to: organic and acquisition growth in our Customer Solutions business; higher volumes in our Organics business; higher collection and disposal volumes from organic customer growth and the acquisition of BBI and other tuck-in acquisitions; and an increase in state, local and other disposal fees associated with higher disposal volumes and higher taxes due to a shift in waste mix type.

• Direct operational costs increased $5.6 million due to: higher costs at our landfills (including increases in leachate treatment costs due to the timing of cell development, landfill gas treatment costs and maintenance costs); higher equipment rental costs associated with an increase in fleet and landfill equipment rentals; an increase in host and royalty fees and higher depletion of landfill operating lease obligations due to increased volumes received at our landfills; and an increase in vehicle insurance costs.

• Maintenance costs increased $4.8 million due to: higher vehicle maintenance costs associated with the integration of the BBI vehicle fleet; higher facility costs associated with unplanned maintenance activities within the Recycling segment; and higher container repair costs.

• Labor and related benefit costs increased $2.3 million due to: the acquisition of BBI; processing higher volumes of commodities through our Recycling segment; and lower productivity as a result of prolonged inclement winter weather.

General and Administration

General and administration expenses include management, clerical and administrative compensation and overhead, professional services and costs associated with marketing, sales force and community relations efforts.

General and Administration – Fiscal Year 2015 compared to Unaudited Calendar Year 2014

Our general and administration expenses increased $6.1 million, or 0.6% as a percentage of revenues, for fiscal year 2015 when compared to calendar year 2014.

The period-to-period change in general and administration expenses can be primarily attributed to the following:

• Labor and related benefit costs increased $3.7 million due to higher wages and salaries, higher incentive compensation costs, and higher equity compensation costs.

• Professional fees increased $1.1 million due to $1.9 million of consulting and legal fees resulting from our responses to the advance notice of nomination sent to us by an activist investor nominating its own candidates for election as directors at our 2015 Annual Meeting in opposition to the three candidates whom we recommended. That activist investor ultimately withdrew its slate of director candidates prior to the 2015 Annual Meeting and all of our director nominees were elected at the 2015 Annual Meeting by our stockholders. These costs were partially offset by lower accounting and audit fees associated with timing changes based on our change in fiscal year-end to December 31^st.

• Other costs increased $1.2 million due to higher property taxes, insurance costs and service agreements.

General and Administration – Transition Period 2014 compared to Unaudited Eight Month Period 2013

Our general and administration expenses increased $4.9 million, or 0.4% as a percentage of revenues, when comparing transition period 2014 to eight month period 2013.

The period-to-period change in general and administration expenses can be primarily attributed to the following:

• Labor and related benefit costs increased $3.8 million due to: additional labor costs associated with growth in our Customer Solutions business; increased overall healthcare costs; and increased incentive compensation costs.

• Professional fees increased $0.9 million due to: accounting and auditing services associated with the change in fiscal year-end; higher legal costs associated with third-party legal advice, including a legal settlement with the New York Attorney General; and a loss accrued for a potential legal settlement with the MADEP. See discussion in Part I, Item 3, “Legal Proceedings” of this Annual Report on Form 10-K.

General and Administration – Fiscal Year 2014 compared to Fiscal Year 2013

Our general and administration expense increased $3.7 million, or 0.4% as a percentage of revenues, for fiscal year 2014 when compared to fiscal year 2013.

The period-to-period change in general and administration expenses can be primarily attributed to the following:

• Labor and related benefit costs increased $5.7 million due to additional personnel costs associated with acquisitions, growth in our Customer Solutions business, recruitment and relocation, and an increase in incentive compensation costs.

• Professional fees decreased $1.3 million due to lower legal costs associated with fewer ongoing legal proceedings and lower consulting costs.

Depreciation and Amortization

Depreciation and amortization includes: (i) depreciation of property and equipment, including assets recorded for capital leases, on a straight-line basis over the estimated useful life 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 our criteria for amortization purposes; (iii) 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 (iv) amortization of intangible assets with a definite life, using either an economic benefit provided approach or a straight-line basis over the definitive terms of the related agreements.

The table below shows, for the periods indicated, the components of depreciation and amortization expense (in millions):

	Twelve Months Ended				Eight Months Ended				Fiscal Year Ended
	December 31,				December 31,				April 30,
	2015		2014		2014		2013		2014		2013
			Unaudited				Unaudited
Depreciation expense	$	33.2	$	32.8	$	21.6	$	21.8	$	33.1	$	34.1
Landfill amortization expense		27.0		25.4		17.9		17.2		24.7		21.2
Other amortization expense		2.5		3.0		2.0		1.6		2.5		1.3
	$	62.7	$	61.2	$	41.5	$	40.6	$	60.3	$	56.6

Depreciation and Amortization – Fiscal Year 2015 compared to Unaudited Calendar Year 2014

The change in the components of depreciation and amortization expense when comparing fiscal year 2015 to calendar year 2014 can primarily be attributed to the following:

• Depreciation expense increased due to: changes in our depreciable asset base as a result of the timing of various capital expenditures, including fleet upgrades and repairs and container purchases, made late in calendar year 2014, partially offset by the impact of various divestitures and asset sales, and the impairment of the asset group of CARES.

• Landfill amortization expense increased due to: an increase in landfill volumes at our Eastern region landfills and at certain of our landfills within the Western region; and an amortization rate adjustment as a result of updating cost estimates and other assumptions associated with the annual year-end review of our landfills.

Depreciation and Amortization – Transition Period 2014 compared to Unaudited Eight Month Period 2013

The change in the components of depreciation and amortization expense when comparing transition period 2014 to eight month period 2013 can primarily be attributed to the following:

• Landfill amortization expense increased during transition period 2014 due to: an increase in landfill volumes at our Southbridge landfill in the Eastern region and at certain of our landfills within the Western region; and an increase in estimated final capping and closure costs at our Worcester landfill.

• Other amortization expense increased during transition period 2014 due to an increase in our intangible assets due to acquisitions made in transition period 2014 and the timing of various acquisitions made in fiscal year 2014.

Depreciation and Amortization – Fiscal Year 2014 compared to Fiscal Year 2013

The change in the components of depreciation and amortization expense when comparing fiscal year 2014 to fiscal year 2013 can primarily be attributed to the following:

• Depreciation expense decreased $1.0 million due to the divestiture of Maine Energy in the third quarter of fiscal year 2013, which reduced our depreciable asset base for all of fiscal year 2014.

• Landfill amortization expense increased $3.5 million due to: an increase in landfill volumes in the Eastern region and at certain of our landfills within the Western region; an increase in estimated final capping and closure costs associated with our Worcester landfill in the Eastern region; and additional post-closure costs associated with the extension of our post-closure commitment at various closed landfills.

• Other amortization expense increased $1.2 million associated with an increase in our amortizable intangible assets due to acquisitions made in fiscal year 2014 and the acquisition of BBI in December 2012.

44

Divestiture Transactions

Sale of Business. In fiscal year 2015, we divested a business, which included the sale of certain assets associated with various waste collection routes in the Western region, for total consideration of $0.9 million, resulting in a gain of $0.6 million.

Maine Energy. In fiscal year 2013, we executed a purchase and sale agreement with the City of Biddeford, Maine, pursuant to which we agreed to sell the real property of Maine Energy to the City of Biddeford. We agreed to sell Maine Energy for an undiscounted purchase consideration of $6.7 million, which is being paid to us in installments over twenty-one years. Later in fiscal year 2013, we closed the transaction, ceased operations of the Maine Energy facility, and initiated the decommissioning, demolition and site remediation process in accordance with the provisions of the agreement. In fiscal year 2015, we completed the demolition process and site remediation under the auspices and in accordance with work plans approved by the Maine Department of Environmental Protection and the EPA. Based on the total incurred costs to fulfill our obligation under the agreement, we reversed a reserve of $1.1 million of excess costs to complete the divestiture in fiscal year 2015.

CARES and Related Transaction. CARES is a joint venture that owned and operated a water and leachate treatment facility for the natural gas drilling industry in Pennsylvania. Our joint venture partner in CARES is Altela. As of December 31, 2015, our ownership interest in CARES is 51%. In accordance with the FASB ASC 810-10-15, we consolidate the assets, liabilities, noncontrolling interest and results of operations of CARES into our consolidated financial statements due to our controlling financial interest in the joint venture.

In fiscal year 2014, we determined that assets of the CARES water treatment facility were no longer operational or were not operating within product performance parameters. As a result, we initiated a plan to abandon and shut down the operations of CARES. It was determined that the carrying value of the assets of CARES was no longer recoverable and, as a result, the carrying value of the asset group was assessed for impairment and impaired. As a result, we recorded an impairment charge of $7.5 million in each of fiscal year 2014 and calendar year 2014 to the asset group of CARES in the Western region.

We executed a purchase and sale agreement in fiscal year 2015 pursuant to which we and Altela agreed to sell certain assets of the CARES water treatment facility to a third-party. We sold these assets of CARES for purchase consideration of $3.5 million, resulting in a gain of $2.9 million in fiscal year 2015, 49% of which was attributable to Altela, the noncontrolling interest holder. As of December 31, 2015, we continued to pursue the dissolution of CARES in accordance with the CARES agreement.

In connection with this transaction, we also sold certain of our equipment and real estate to the same third-party for total consideration of $1.1 million, resulting in a gain of $0.9 million in fiscal year 2015.

BioFuels. As a part of the disposition of BioFuels, we agreed to complete certain site improvements that were completed in transition period 2014. As a result, we recorded a $0.6 million gain in each of transition period 2014 and calendar year 2014 associated with reversing the excess remaining reserves not needed to complete the site improvements.

Contract Settlement Charge

In fiscal year 2015, we recorded a contract settlement charge of $1.9 million associated with the Expera Old Town, LLC v. Casella Waste Systems, Inc. legal matter. See Item 3, “Legal Proceedings” and Note 10, Commitments and Contingencies to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for further disclosure.

Development Project Charge

In each of fiscal year 2014 and calendar year 2014, we recorded a charge of $1.4 million for deferred costs associated with a gas pipeline development project no longer deemed viable.

Environmental Remediation Charge

In each of transition period 2014 and calendar year 2014, we recorded an environmental remediation charge of $1.0 million associated with remediation performed at our Southbridge landfill in the Eastern region. We had previously recorded an environmental remediation charge of $0.4 million in eight month period 2013 and fiscal year 2014 associated with remediating this site.

45

Severance and Reorganization Costs

In calendar year 2014, eight month period 2013 and fiscal year 2014, we recorded charges of $0.4 million, $0.2 million and $0.6 million, respectively, for severance costs associated with various planned reorganization efforts including the divestiture of Maine Energy.

In fiscal 2013, we recorded a charge of $3.7 million for severance costs associated primarily with the realignment of our operations in order to streamline functions and improve our cost structure, the closure of Maine Energy and a reorganization of senior management. Through the realignment of our operations we improved certain aspects of the sales function to facilitate customer service and retention, pricing growth and support of strategic growth initiatives; align transportation, route management and maintenance functions at the local level; and reduce corporate overhead and staff to match organizational needs and reduce costs.

Expense from Divestiture, Acquisition and Financing Costs

The $0.1 million expense from divestiture, acquisition and financing costs recorded in each of eight month period 2013 and fiscal year 2014 is primarily associated with legal costs related to the acquisition of the remaining 50% membership interest of Tompkins.

The $1.4 million expense from divestiture, acquisition and financing costs recorded in fiscal year 2013 is associated with the following fiscal year 2013 events: a $0.3 million write-off of costs associated with the full refinancing of our 11.0% senior second lien notes (“Second Lien Notes”) in fiscal year 2013, $0.6 million of legal costs associated with the Maine Energy divestiture transaction, and $0.5 million of costs associated with the BBI acquisition.

Gain on Settlement of Acquisition Related Contingent Consideration

In each of fiscal year 2014 and calendar year 2014, we recovered a portion of the purchase price holdback amount we had previously paid and were relieved of any potential contingent consideration obligation associated with the acquisition of an industrial service management business earlier in fiscal year 2014. As a result, we recorded a $1.1 million gain on settlement of acquisition related contingent consideration in each of fiscal year 2014 and calendar year 2014.

Other Expenses

Interest Expense, net

Interest Expense, net – Fiscal Year 2015 compared to Unaudited Calendar Year 2014

Our interest expense, net increased $2.0 million in fiscal year 2015 as compared to calendar year 2014 due to higher average debt balances combined with changes to our capitalization structure associated with various tax exempt debt borrowings, the issuance of additional 2019 Notes and the refinancing of our Senior Credit Facility. In fiscal year 2015, we also experienced interest savings when we repurchased and permanently retired $14.7 million aggregate principal amount of 2019 Notes, our most expensive debt, at a weighted average repurchase price of $101.0.

Interest Expense, net – Transition Period 2014 compared to Unaudited Eight Month Period 2013

Our interest expense, net increased $0.2 million in transition period 2014 as compared to eight month period 2013 as interest expense associated with higher average debt balances in transition period 2014 was partially offset by interest savings associated with a reduction to our outstanding letters of credit.

Interest Expense, net – Fiscal Year 2014 compared to Fiscal Year 2013

Our interest expense, net decreased $3.5 million in fiscal year 2014 when compared to fiscal year 2013. The decrease in interest expense, net during fiscal year 2014 can primarily be attributed to lower interest rates associated with the refinancing in October and November 2012 of $180.0 million in aggregate principal amount of Second Lien Notes. Interest savings were partially offset by an increase in interest expense associated with higher average debt balances in fiscal year 2014, associated primarily with borrowings under our Senior Credit Facility to help fund operations and meet cash flow needs.

46

Loss from Equity Method Investment and Gain on Sale of Equity Method Investment

In December 2013, we sold our 50% membership interest in GreenFiber and purchased the remaining 50% membership interest of Tompkins, both of which were previously accounted for using the equity method of accounting.

As a result of the sale of our 50% membership interest in GreenFiber, we recorded a gain on sale of equity method investment of $0.8 million in eight month period 2013, which included a $0.2 million working capital adjustment to the purchase price that was finalized upon closing of the transaction in January 2014. We had initially recorded a gain on sale of equity method investment of $0.6 million in fiscal year 2014 as a result of the sale.

We no longer account for our investment in Tompkins using the equity method of accounting and began including the accounts of Tompkins in our consolidated financial statements.

Prior to these transactions, we recorded income from equity method investments of $0.1 million in calendar year 2014 and losses from our equity method investments of $1.0 million, $0.9 million and $4.4 million in eight month period 2013, fiscal year 2014 and fiscal year 2013.

Impairment of Investments

As of December 31, 2015, we owned 5.3% of the outstanding common stock of Recycle Rewards, Inc. (“Recycle Rewards”), a company that markets an incentive based recycling service. In both fiscal year 2015 and transition period 2014, 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 2015, and had a valuation analysis performed by a third-party valuation specialist in transition period 2014, both of 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 these analyses, it was determined in each case that the fair value of our cost method investment in Recycle Rewards was less than the carrying amount and, therefore, we recorded other-than-temporary investment impairment charges of $1.1 million in fiscal year 2015 and $2.3 million in each of calendar year 2014 and transition period 2014. As of December 31, 2015, the carrying amount of our cost method investment in Recycle Rewards is $1.1 million.

As of December 31, 2015, we owned 9.8% of the outstanding equity value of GreenerU, Inc. (“GreenerU”), a services company focused on providing energy efficiency, sustainability and renewable energy solutions to colleges and universities. In fiscal year 2015, it was determined based on the operating performance and recent third-party interest in GreenerU that our cost method investment in GreenerU was potentially impaired. A valuation analysis was performed by a third-party valuation specialist using a market approach based on an option pricing methodology to determine an equity value and fair market value per share for GreenerU. Based on this analysis, it was determined that the fair value of our cost method investment in GreenerU was less than the carrying amount and, therefore, we recorded an other-than-temporary investment impairment charge of $0.7 million in fiscal year 2015. As of December 31, 2015, the carrying amount of our cost method investment in GreenerU is $0.3 million.

As of December 31, 2015, we owned 17.0% and 16.2% of the outstanding common stock of AGreen Energy LLC (“AGreen”) and BGreen Energy LLC (“BGreen”), respectively. In fiscal year 2015, AGreen and BGreen, both of which we account for as cost method investments, entered into agreements that resulted in the contribution and sale of certain assets and liabilities of AGreen and BGreen to a limited liability company in exchange for partial ownership interests in a parent of that limited liability company. As a result of the transactions, we performed an analysis to determine whether an other-than-temporary impairment in the carrying value of our cost method investments had occurred. Based on the analysis performed, which measured the fair value of our cost method investments using an in-exchange valuation premise under the market approach that utilized the estimated purchase consideration received, we recorded an other-than-temporary investment impairment charge of $0.3 million in fiscal year 2015.

Loss on Derivative Instruments

In the fiscal year ended April 30, 2012, we entered into two forward starting interest rate derivative agreements that were initially being used to hedge the interest rate risk associated with the forecasted financing transaction to redeem our Second Lien Notes. The total notional amount of these agreements was $150.0 million and required us to receive interest based on changes in LIBOR and pay interest at a rate of approximately 1.40%. During fiscal year 2013, we dedesignated both of the $75.0 million forward starting interest rate derivative agreements and discontinued hedge accounting in accordance with FASB ASC 815-30 because the interest payments associated with the forecasted financing transaction were no longer deemed probable. We recognized a $3.6 million loss, reclassified

47

from accumulated other comprehensive loss, as loss on derivative instruments in fiscal year 2013 and recognize the change in fair value of the interest rate swaps along with any cash settlements through earnings as gain or loss on derivative instruments. The agreements were both scheduled to mature on March 15, 2016. However, in February 2015 we settled one of the forward starting interest rate derivative agreements for $0.8 million.

Loss on Debt Extinguishment

Senior Subordinated Notes. In fiscal year 2015, we repurchased and permanently retired $14.7 million aggregate principal amount of 2019 Notes at a weighted average repurchase price of $101.0 in order to maximize interest savings by paying down our most expensive debt. As a result of the repurchases, we recorded a charge of $0.5 million in fiscal year 2015 as a loss on debt extinguishment primarily related to the non-cash write off of deferred financing costs and unamortized original issue discount in proportion with the settlement amount.

Senior Credit Facility. In fiscal year 2015, we recorded a charge of $0.5 million as a loss on debt extinguishment related to the write-off of deferred financing costs in connection with changes to the borrowing capacity from the Senior Credit Facility to the ABL Facility. The remaining unamortized deferred financing costs of the Senior Credit Facility, along with fees paid to the creditor and third-party costs incurred for the ABL Facility, are to be amortized over the term of the ABL Facility.

Second Lien Notes. In fiscal year 2013, we recorded a charge of $15.6 million as a loss on debt extinguishment related to the full refinancing of our Second Lien Notes. The loss on debt extinguishment consisted of a $2.8 million non-cash write off of deferred financing costs, a $2.1 million non-cash write off of the unamortized original issue discount and a $10.7 million charge associated with the early tender premium and tender fees associated with the redemption of the Second Lien Notes.

Provision (Benefit) for Income Taxes

Our provision for income taxes from continuing operations for fiscal year 2015 increased $0.1 million to $1.4 million from $1.3 million in calendar year 2014. The provision (benefit) for income taxes decreased $0.5 million in transition period 2014 to $0.7 million from $1.2 million in eight month period 2013, and increased $4.3 million in fiscal year 2014 to $1.8 million from ($2.5) million in fiscal year 2013. The provisions for income taxes for fiscal year 2015 and calendar year 2014 include deferred tax provisions of $0.8 and $1.2 million, respectively, and transition period 2014 and eight month period 2013 include deferred tax provisions of $0.6 million and $1.0 million, respectively. The change in the provisions for income taxes and the total deferred tax provisions in these periods are primarily related to the deferred tax liability for indefinite lived assets. Since we cannot determine when the deferred tax liability related to indefinite lived assets will reverse, this amount cannot be used as a future source of taxable income against which to benefit deferred tax assets. The change in the provisions (benefits) for income taxes for fiscal year 2014 and fiscal year 2013 is primarily related to a ($5.1) million deferred tax benefit in fiscal year 2013 due to a reduction of the valuation allowance in connection with the recording of deferred tax liabilities related to the BBI acquisition, offset by $0.8 million in fiscal year 2013 related to a settlement with the State of New York for corporate franchise tax for tax years April 30, 2004 through April 30, 2010.

Discontinued Operations

Income (Loss) from Discontinued Operations, net

Discontinued operations in eight month period 2013 and fiscal years 2014 and 2013 represent the result of operations related to the business disposition of BioFuels. In fiscal year 2014, we executed a purchase and sale agreement with ReEnergy, pursuant to which we agreed to sell certain assets of BioFuels, which is located in our Eastern region, to ReEnergy.

Our loss from discontinued operations, net in fiscal year 2013 includes a $3.3 million loss associated with the adjustment to the carrying value of BioFuels to its fair value as a result of the planned business disposition of BioFuels.

The operating results of the operations discussed above have been included in discontinued operations in the accompanying consolidated financial statements.

Loss on Disposal of Discontinued Operations

We recognized a $0.4 million loss on disposal of discontinued operations in fiscal year 2014 associated with the BioFuels disposition.

• The price change component in fiscal year 2015 total solid waste revenues growth is the result of $3.1 million from favorable collection pricing and $1.1 million from favorable disposal pricing related to landfills and transfer stations.

49

Volume.

• The volume change component in fiscal year 2015 total solid waste revenues growth is primarily the result of $6.7 million from higher disposal volumes and $3.7 million from higher collection volumes.

Acquisitions and divestitures.

• The acquisitions and divestitures change component in fiscal year 2015 total solid waste revenues growth is the result of increased revenues from the acquisition of a solid waste hauling operation in October 2014.

Closed landfill.

• The closed landfill change component in fiscal year 2015 total solid waste revenues growth is the result of our Worcester landfill, which ceased operations in April 2014 in accordance with its permit.

Eastern region operating income increased $9.0 million during fiscal year 2015 when compared to calendar year 2014. This improvement is primarily attributable to revenue growth outlined above and the following cost changes:

• Cost of operations: Cost of operations increased by $1.8 million primarily due to: additional labor costs due to higher collection and transfer station volumes associated with new municipal contracts and organic customer growth; higher operating costs at one of our landfills; and higher facility and fleet maintenance costs. These costs were partially offset by lower diesel fuel prices, lower gas treatment costs at Juniper Ridge, lower operating costs associated with our Worcester landfill closing and the expiration of an out-of-market put-or-pay waste disposal contract.

• General and administration: General and administration expenses increased by $4.5 million primarily due to higher shared overhead costs and an increase in incentive compensation.

• Depreciation and amortization: Depreciation and amortization expense increased by $1.0 million due to an increase in landfill volumes and an amortization rate adjustment at one of our landfills as a result of updating cost estimates and other assumptions associated with the annual year-end review of our landfills.

• Other: Other significant charges include the contract settlement charge of $1.9 million in fiscal year 2015, the reversal of $1.1 million of excess costs to complete the divestiture of Maine Energy in fiscal year 2015, the $1.0 million environmental remediation charge associated with the environmental remediation at our Southbridge landfill in calendar year 2014, severance costs associated with various planned reorganization efforts in calendar year 2014, and a $1.4 million write off of deferred costs associated with a gas pipeline development project no longer deemed to be viable in calendar year 2014.

50

Volume.

• The volume change component in transition period 2014 total solid waste revenues growth is the result of $3.1 million from higher disposal volumes (which includes a mix shift in volumes from landfills to transfer stations), $2.5 million from higher collection volumes and $0.2 million from higher processing volumes.

Commodity price and volume.

• The solid waste operations commodity price and volume change component in transition period 2014 total solid waste revenues growth is the result of $0.2 million from lower power generation and processing commodity volumes, partially offset by $0.1 million from favorable commodity pricing within power generation.

Acquisitions and divestitures.

• The acquisitions and divestitures change component in transition period 2014 total solid waste revenues growth is the result of the acquisition of two solid waste hauling operations, one in September 2013 and another in October 2014, and a transfer station in November 2013.

Closed landfill.

• The closed landfill change component in transition period 2014 total solid waste revenues growth is the result of our Worcester landfill, which ceased operations in April 2014 in accordance with its permit.

Eastern region operating income decreased $0.5 million during transition period 2014 when compared to eight month period 2013. The change in operating income is primarily attributable to the following cost changes:

• Cost of operations: Cost of operations increased by $9.5 million, resulting in margin erosion as costs increased at a greater rate than revenues. The change was primarily due to: an increase in third-party direct costs associated with higher collection and disposal volumes from new municipal contracts, organic customer growth and the acquisition of a transfer station; and an increase in other operational costs, including labor (which is driven by higher collection and transfer volumes), healthcare, depletion of landfill operating lease obligations at Southbridge, and maintenance costs associated with hauling operations and certain of our landfills. These costs were partially offset by a decrease in fleet and landfill equipment rentals, as well as host community fees and royalties; lower accretion expense related to accrued final capping, closure and post-closure costs associated with our Worcester landfill; and lower leachate treatment costs.

• General and administration: General and administration expenses increased $0.9 million primarily due to: an increase in bad debt expense in transition period 2014 associated with increased customer growth and bad debt recoveries in eight month period 2013; an increase in incentive compensation costs; and a loss accrued for a potential legal settlement with MADEP. See discussion in Part I, Item 3, “Legal Proceedings” of this Annual Report on Form 10-K.

• Depreciation and amortization: Depreciation and amortization costs remained flat primarily due to lower landfill amortization associated with our Worcester landfill, which no longer accepted waste in transition period 2014, offset by an increase in other amortization associated with acquired intangible assets.

• Other: Other charges impacting operating income included a $1.0 million environmental remediation charge recorded in transition period 2014 and a $0.4 million environmental remediation charge recorded in eight month period 2013 associated with the environmental remediation at Southbridge.

• The acquisitions and divestitures change component in fiscal year 2014 total solid waste revenues growth is the result of $14.4 million from the acquisition of BBI, partially offset by $7.4 million from the divestiture of Maine Energy.

Closed landfill.

• The closed landfill change component in fiscal year 2014 total solid waste revenues growth is the result of our Worcester landfill, which stopped accepting waste in fiscal year 2013 based on the attainment of its permitted capacity. The impact of the closure was limited in fiscal year 2014 as we were granted a permit in May 2013 to accept an additional 0.2 million tons of waste. We began placing additional waste pursuant to the permit at the end of June 2013 and ceased placing tons in April 2014.

Eastern region operating loss decreased $4.2 million during fiscal year 2014 when compared to fiscal year 2013. The change in operating income is primarily attributable to the following cost changes:

• Cost of operations: Cost of operations increased by $19.1 million in fiscal year 2014 primarily due to: an increase in third-party direct costs associated with higher disposal volumes from organic customer growth and the acquisition of BBI and other operations, partially offset by a reduction of transportation costs associated with the divestiture of Maine Energy; and an increase in direct operational costs including labor, fuel, equipment rentals, landfill gas treatment costs at one of our landfills and fleet maintenance and repair costs associated with the integration of the BBI vehicle fleet, partially offset by a reduction of facility costs associated with the divestiture of Maine Energy.

• General and administration: General and administration costs increased $0.9 million in fiscal year 2014 primarily due to additional personnel costs associated with the BBI acquisition and an increase in estimated incentive compensation costs.

• Depreciation and amortization: Depreciation and amortization costs increased $1.4 million in fiscal year 2014 due to the following: an increase in landfill amortization costs associated with higher landfill volumes; an increase in estimated costs associated with our Worcester landfill in closure status; and depreciation expense savings associated with the divestiture of Maine Energy.

• Other: Other charges impacting operating loss in fiscal year 2014 include: a $1.4 million write off of deferred costs in fiscal year 2014 associated with a gas pipeline development project no longer deemed to be viable; a $0.4 million environmental remediation charge recorded in fiscal year 2014 associated with the remediation of Southbridge; severance costs associated primarily with realignment and the streamlining of functions to improve our cost structure and the divestiture of Maine Energy in the third quarter of fiscal year 2013; legal costs associated with the Maine Energy divestiture transaction; and costs associated directly with the BBI acquisition.

• The acquisitions and divestitures change component in fiscal year 2015 total solid waste revenues growth is the result of increased revenues from the acquisition of a solid waste hauling operations in September 2014, partially offset by decreased revenues associated primarily with an asset exchange in December 2014 and the divestiture of a business in May 2015.

53

Western region operating income increased $11.0 million during fiscal year 2015 when compared to the calendar year 2014. This improvement is primarily attributable to revenue growth outlined above and the following cost changes:

• Cost of operations: Cost of operations increased by $2.0 million due to: higher disposal volumes associated with organic customer growth, two new transfer station contracts and the acquisition of a solid waste hauling operation; higher equipment rental costs; higher third-party landfill disposal costs; higher operating and leachate disposal costs at certain landfills; and higher fleet maintenance costs. Increased costs were partially offset by lower diesel fuel prices, lower depletion of landfill operating lease obligations at a landfill due to a decrease in tons and a favorable rate impact associated with the annual year-end review of our landfills, lower purchased material costs and lower benefit costs.

• General and administration: General and administration expenses increased by $3.0 million primarily due to higher shared overhead costs, higher bad debt expense associated with an increase in the reserve for a specific landfill customer and higher personnel costs.

• Depreciation and amortization: Depreciation and amortization expenses increased $0.1 million due to higher amortization expense associated with an increase in overall landfill tons and changes to certain of our landfill amortization rates as a part of the annual year-end review of our landfills, mostly offset by a decrease in depreciation expense associated with a lower depreciable asset base.

• Other: We recorded a $0.6 million gain associated with the divestiture of a business, which included the sale of certain assets associated with various waste collection routes, and a $3.8 million gain associated with the disposal of certain assets of the CARES water treatment facility and certain of our equipment and real estate in a related transaction in fiscal year 2015. In fiscal year 2014, we recorded an impairment charge of $7.5 million to the abandoned asset group of CARES.

Western region operating income increased $1.6 million during transition period 2014 as compared to eight month period 2013. The change in operating income is primarily attributable to the solid waste revenues growth discussed above combined with the following cost changes:

• Cost of operations: Cost of operations increased by $6.0 million due to: an increase in third-party direct costs associated with higher hauling costs driven by transfer station volume growth (including the addition of new operating contracts for municipality-owned transfer stations) and landfill volume growth, partially offset by lower disposal costs driven by the winding down of business at CARES and lower collection volumes; an increase in other operational costs, including healthcare, depletion of landfill operating lease obligations (due to increased landfill volumes), host community fees and royalties fees, and maintenance costs associated with our fleet, hauling facilities and landfill facilities. These costs were partially offset by decreased fuel costs associated with lower diesel fuel prices in the marketplace.

• General and administration: General and administration costs remained flat due to a higher than normal bad debt expense in eight month period 2013 due to collectability issues associated with two disposal customers being offset by higher healthcare costs and increased incentive compensation costs.

• Other: Other charges impacting operating income include the CARES impairment in fiscal year 2014 and severance costs associated with realignment and streamlining of functions to improve our cost structure in fiscal year 2013.

Recycling

Recycling – Fiscal Year 2015 compared to Unaudited Calendar Year 2014

Recycling revenues decreased $2.0 million during fiscal year 2015 when compared to calendar year 2014. The decrease in revenues is the result of unfavorable commodity prices in the marketplace, partially offset by higher commodity volumes and higher tipping fees.

Recycling operating loss increased by $0.7 million during fiscal year 2015 when compared to calendar year 2014 as operating results were negatively impacted by unfavorable commodity prices, higher hauling and labor costs, increased facility maintenance activities and higher shared overhead costs, partially offset by higher processing fees charged to third-party and intercompany customers.

Recycling – Transition Period 2014 compared to Unaudited Eight Month Period 2013

Recycling revenues increased $4.5 million during transition period 2014 when compared to eight month period 2013. The increase in revenues is primarily the result of higher commodity volumes, and the acquisition of the remaining 50% membership interest of Tompkins.

Recycling operating loss decreased by $0.8 million during transition period 2014 when compared to eight month period 2013 due to increased revenues and improved operating efficiencies, partially eroded by higher commodity purchased material costs, higher labor and healthcare costs, and increased facility maintenance activities.

56

Recycling – Fiscal Year 2014 compared to Fiscal Year 2013

Recycling revenues increased $1.5 million during fiscal year 2014 when compared to fiscal year 2013. The increase in revenues is due to higher commodity volumes and the acquisition of the remaining 50% membership interest of Tompkins.

Recycling operating loss for fiscal year 2014 increased by $1.7 million when compared to fiscal year 2013 due to extended inclement weather that resulted in lower operating productivity and reduced processing throughput, along with unplanned maintenance activities.

Other

Other – Fiscal Year 2015 compared to Unaudited Calendar Year 2014

Other revenues decreased $0.1 million during fiscal year 2015 when compared to calendar year 2014 primarily due to volume declines in our Organics business associated with lower commodity volumes and a decline in our floating rate fuel and oil recovery fee in response to lower diesel fuel index prices on which the surcharge is based, and a decline in transportation volumes. This was partially offset by organic business growth within our Customer Solutions business.

Other operating income increased by $0.5 million during fiscal year 2015 when compared to calendar year 2014 based on the operating performance of our Customer Solutions business. Profitability in the Customer Solutions business improved as we continued to gain leverage on higher revenues and lower general and administration costs.

Other – Transition Period 2014 compared to Unaudited Eight Month Period 2013

Other revenues increased $11.3 million during transition period 2014 as compared to eight month period 2013 primarily as a result of higher volumes associated with organic business growth within our Customer Solutions business and, to a lesser extent, the acquisition of an industrial service management business in September 2013 and commodity volume increases within our Organics business.

Other operating income decreased by $1.7 million during transition period 2014 when compared to eight month period 2013 as increased revenues were more than offset by increased third-party direct costs (including hauling and purchased material costs associated primarily with our Customer Solutions business and, to a lesser extent, hauling costs associated with our Organics business) and labor and related benefit costs associated with growth in our Customer Solutions business.

Other – Fiscal Year 2014 compared to Fiscal Year 2013

Other revenues increased $12.2 million during fiscal year 2014 when compared to fiscal year 2013. Increased revenues for fiscal year 2014 was primarily the result of higher volumes within our Organics business and organic growth and the acquisition of an industrial service management business within our Customer Solutions business in fiscal year 2014.

Other operating income for fiscal year 2014 increased by $3.8 million when compared to fiscal year 2013 as increased revenues, combined with cost savings associated with a change in our organizational and management structure and the head count reduction that took place as a part of the reorganization fiscal year 2013, more than offset increased hauling and transportation costs associated with our Organics business and transportation services and increased third-party direct costs associated with the acquisition of an industrial service management business within our Customer Solutions business.

Liquidity and Capital Resources

We 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 a revolving credit facility.

The most significant items affecting the change in our operating cash flows are summarized below:

• Improved operational performance in fiscal year 2015 as revenues increased by $20.6 million, whereas cost of operations and general and administration costs increased only $11.5 million, a decrease of 1.1% as a percentage of revenues.

• Improved 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. The improvement in fiscal year 2015 was the result of the favorable cash flow impacts associated with prepaid expenses, inventories and other assets and accrued expenses and other liabilities due to lower final capping, closure and post-closure payments, partially offset by the unfavorable cash flow impacts associated with accounts payable and accounts receivable.

Net cash used in investing activities. Cash flows used in investing activities decreased by $23.0 million during fiscal year 2015 when compared to calendar year 2014.

The most significant items affecting the change in our investing cash flows are summarized below:

• Capital expenditures. Capital expenditures were $17.5 million lower in the fiscal year 2015 due to the timing of various landfill development projects, along with various calendar year 2014 capital expenditures associated with a new recycling facility contract, various transfer stations and the installation of a landfill gas treatment system at Juniper Ridge.

• Proceeds from divestiture transactions. We divested a business, certain assets of the CARES water treatment facility, and other equipment of ours as a result of the CARES transaction for cash consideration of $5.3 million in fiscal year 2015.

Net cash (used in) provided by financing activities. Cash flows from financing activities decreased $28.8 million during fiscal year 2015 when compared to calendar year 2014.

59

The most significant items affecting the change in our financing cash flows are summarized below:

• Debt activity. We issued an additional $60.0 million of 2019 Notes and refinanced our Senior Credit Facility resulting in an increase in both debt borrowings and debt payments in fiscal year 2015. In the aggregate, we were able to pay down $15.8 million, net, of long-term debt in fiscal year 2015, including the purchase for settlement of $14.7 million aggregate principal amount 2019 Notes, whereas we increased our long-term debt by $15.3M, net in calendar year 2014.

• Payments of financing costs. We had a $6.4 million increase in deferred financing cost payments in fiscal year 2015 related primarily to the issuance of an additional $60.0 million of 2019 Notes and $15.0 million of Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2015 (“FAME Bonds 2015”) and the refinancing of our Senior Credit Facility.

• Distribution to noncontrolling interest holder. In fiscal year 2015, we distributed $1.5 million to Altela representing its pro-rata share of the proceeds associated with the disposal of certain assets of CARES.

• Change in restricted cash. We added $5.6 million of restricted assets associated with the issuance of the FAME Bonds 2015 that represent restricted cash reserved for repayment of costs incurred to fund certain capital projects in the State of Maine, and used $10.0 million of the restricted cash associated with the issuance of the FAME Bonds 2015 and the $5.8 million of New York State Environmental Facilities Corporation Solid Waste Disposal Revenue Bonds Series 2014 (“New York Bonds”) issued in calendar year 2014, to pay down ABL Facility borrowings used to finance certain capital projects in the States of New York and Maine.

Cash Flow Activity – Transition Period 2014 compared to Unaudited Eight Month Period 2013

Net cash flows provided by operating activities. Cash flows from operating activities increased by $12.5 million for transition period 2014 when compared to eight month period 2013.

The following is a summary of our operating cash flows (in millions) for transition period 2014 and eight month period 2013:

	Eight Months Ended December 31,

Changes in assets and liabilites, net		(11.7	)		(23.0	)
Net cash provided by operating activities	$	38.3		$	25.8

The most significant items affecting the change in our operating cash flows are summarized below:

• Improved operational performance in the transition period 2014 as revenues increased by $28.3 million, partially offset by higher cost of operations and general and administration costs, which increased by $27.5 million or 1.2% as a percentage of revenues.

• Improved 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. This improvement is primarily due to the favorable impact associated with the change in accounts payable based on the timing of payments. This was partially offset by the unfavorable impact associated with the change in accrued expenses and other liabilities (associated primarily with the amount and timing of capping, closure and post closure payments and the timing of accrued interest payments) and the unfavorable impact associated with the change in prepaid expenses, inventories and other assets.

60

• Cash interest payments decreased $0.3 million from $18.7 million for eight month period 2013 to $18.4 million for transition period 2014 primarily due to the timing of payments associated with changes to our capitalization structure.

Net cash used in investing activities. Cash flows used in investing activities increased by $13.9 million for transition period 2014 when compared to eight month period 2013.

The most significant items affecting the change in our investing cash flows are summarized below:

• Capital expenditures. Capital expenditures were $21.6 million higher primarily due to organic business growth (including increased spending on our fleet), the installation of a gas treatment system at Juniper Ridge, various landfill development costs, and other capital investments associated with certain new contracts and a new MRF in Lewiston, Maine.

• Proceeds from the sale of equity method investment. During eight month period 2013, we and LP sold our membership interests in GreenFiber. After netting indebtedness of GreenFiber and transaction costs, our 50% of the net cash proceeds amounted to $2.8 million.

• Payments related to investments. During eight month period 2013, we made investments in unconsolidated entities totaling $2.0 million, whereas we made no payments related to investments in transition period 2014.

• Acquisitions, net of cash acquired. During eight month period 2013, cash outflows associated with acquisitions totaled $8.5 million as compared to $0.4 million in transition period 2014 based on the respective acquisition activity. The timing and size of acquisitions are dependent upon opportunity and our access to capital.

Net cash provided by financing activities. Cash flows provided by financing activities decreased $1.8 million during transition period 2014 when compared to eight month period 2013.

The most significant items affecting the change in our financing cash flows are summarized below:

• Change in restricted cash. We had $5.8 million in restricted cash associated with the issuance of the New York Bonds.

• Payments of financing costs. We had a $2.2 million increase in deferred financing cost payments related to the issuance of the New York Bonds, the issuance of $11.0 million in aggregate principal amount of tax-exempt Solid Waste Disposal Revenue Bonds Series 2013 issued by the Business Finance Authority of the State of New Hampshire (“New Hampshire Bonds”), and the refinancing of our Senior Credit Facility.

• Debt activity. We had both an increase in debt borrowings, $26.6 million (associated with the issuance of the New York and New Hampshire Bonds, along with higher capital expenditures), and debt payments, $20.6 million (associated with the pay down of our Senior Credit Facility using the net proceeds from the issuance of New York Bonds and New Hampshire Bonds).

Net cash provided by (used in) discontinued operations. Cash flows from discontinued operations increased $1.9 million during transition period 2014 when compared to eight month period 2013 due to repayment in full of the remainder of the $2.0 million note receivable associated with the business disposition of BioFuels.

Cash Flow Activity – Fiscal Year 2014 compared to Fiscal Year 2013

Net cash flows provided by operating activities. Cash flows provided by operating activities increased by $5.7 million for fiscal year 2014 when compared to fiscal year 2013.

The following is a summary of our operating cash flows (in millions) for fiscal year 2014 and fiscal year 2013:

	Fiscal Year Ended April 30,

Changes in assets and liabilites, net		(9.1	)		0.6
Net cash provided by operating activities	$	49.6		$	43.9

The most significant items affecting the change in our operating cash flows are summarized below:

• Improved operational performance in fiscal year 2014 as revenues increased by $42.3 million, whereas cost of operations and general and administration costs increased only $35.3 million and remained consistent as a percentage of revenues.

• Interest payments decreased $6.2 million in fiscal year 2014 due to the timing of payments, as well as lower interest rates as a result of the refinancing in October and November of 2012 of $180.0 million in aggregate principal amount of 11.0% Second Lien Notes. This reduction was partially offset by an increase in interest payments associated with higher average debt balances.

• Increases were partially offset by the 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. This decline is due to the unfavorable impact associated with the change in accounts payable, the unfavorable impact associated with the change in prepaid expenses, inventories and other assets and the unfavorable impact associated with the change in accounts receivable, partially offset by the favorable impact associated with the change in accrued expenses and other liabilities.

Net cash used in investing activities. Cash flows used in investing activities decreased by $31.6 million for fiscal year 2014 when compared to fiscal year 2013.

The most significant items affecting the change in our investing cash flows are summarized below:

• Acquisitions, net of cash acquired. During fiscal year 2014, we acquired various businesses including several solid waste hauling operations, a transfer station, a MRF and an industrial service management business (included in the Other segment) for total consideration of $10.1 million, of which we have made $8.5 million in cash payments. In the fourth quarter of fiscal year 2014, we recovered $0.2 million of the purchase price holdback amount we had previously paid and were relieved of any potential contingent consideration obligation associated with the acquisition of an industrial service management business in fiscal year 2014. This is compared to fiscal year 2013, when we acquired six solid waste hauling operations in the Western region and acquired all of the outstanding capital stock of BBI in the Eastern region for total consideration of $28.0 million, of which we paid $24.8 million in cash and made $0.5 million in holdback payments in fiscal year 2013.

62

• Investments in unconsolidated entities. During fiscal year 2014, we made investments in unconsolidated entities totaling $2.1 million compared to $3.2 million in fiscal year 2013.

• Capital expenditures. Lower capital expenditures of $9.1 million in fiscal year 2014 related primarily to the timing of landfill development projects and a decrease in spending related to facilities.

Net cash provided by financing activities. Cash flows provided by financing activities decreased $35.9 million for fiscal year 2014 when compared to fiscal year 2013.

The most significant items affecting the change in our financing cash flows are summarized below:

• Stock issuance. We sold 11.5 million shares of Class A common stock in fiscal year 2013 and received net proceeds from the registered public offering of $42.2 million, after deducting underwriting discounts, commissions and offering expenses.

• Debt activity. We experienced a reduction in both debt payments, by $208.5 million, due primarily to the full redemption of the Second Lien Notes in fiscal year 2013, and debt borrowings, by $214.7 million, due primarily to the offering of $125.0 million in additional 2019 Notes in fiscal year 2013, resulting in a $6.2 million decrease in cash flows related to debt activity in fiscal year 2014 compared to fiscal year 2013.

• Payment of financing costs. We made lower payments of financing costs of $4.2 million in fiscal year 2014 due primarily to the offering of $125.0 million in additional 2019 Notes in fiscal year 2013.

• Tender premium and costs. We paid a tender premium and tender costs of $10.7 million in fiscal year 2013 in connection with the redemption of the Second Lien Notes.

Net cash used in discontinued operations. Cash flows used in discontinued operations decreased $2.2 million for fiscal year 2014 when compared to fiscal year 2013. These fluctuations in net cash flows from discontinued operations are the result of the business disposition of BioFuels in exchange for a $2.0 million note receivable, which was to be paid to us in equal quarterly installments commencing November 1, 2013.

Outstanding Long-Term Debt

Asset-Based Lending Facility

The ABL Facility consists of a revolving credit facility with loans thereunder being available up to an aggregate principal amount of $190.0 million, subject to availability under a borrowing base formula as defined in the ABL Facility agreement. We have the right to request, at our discretion, an increase in the amount of loans under the ABL facility by an aggregate amount of $100.0 million, subject to the terms and conditions set forth in the ABL Facility agreement. Interest accrues at LIBOR plus between 1.75% and 2.50%, subject to the terms of the ABL Facility agreement and is set at LIBOR plus 2.25% as of December 31, 2015. The ABL Facility matures on February 26, 2020. If we fail to refinance the 2019 Notes on or before November 16, 2018, the maturity date of the ABL Facility will be November 16, 2018. The ABL Facility is guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries and is collateralized by certain qualified accounts receivable-trade, inventory and property, plant and equipment.

The ABL Facility agreement requires us to maintain minimum consolidated EBITDA for the twelve months preceding the measurement date measured at the end of each fiscal quarter. Minimum consolidated EBITDA is a non-GAAP financial measure 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. As of December 31, 2015, we were in compliance with the minimum consolidated EBITDA financial covenant contained in the ABL Facility agreement as follows (in millions):

Asset-Based Revolving Credit Facility Financial Covenants	Fiscal Year Ended December 31, 2015		Covenant Requirements at December 31, 2015
Minimum consolidated EBITDA (1)	$	110.5	$	75.0 Min.

(1) Minimum consolidated EBITDA is based on operating results for the twelve months preceding the measurement date, December 31, 2015. Based on the minimum consolidated EBITDA, our consolidated leverage ratio, as defined in the ABL

63

Facility, was 4.75 as of December 31, 2015. The consolidated leverage ratio is used to set pricing according to the ABL Facility agreement and there is no financial covenant associated with this ratio. A reconciliation of net cash provided by operating activities to minimum consolidated EBITDA is as follows (in millions):

	Fiscal Year Ended December 31, 2015
Net cash provided by operating activities	$	70.5
Changes in assets and liabilities, net of effects of acquisitions and divestitures		(5.0	)
Divestiture transactions		5.5
Gain on sale of property and equipment		0.1
Loss on debt extinguishment		(1.0	)
Stock based compensation, net of excess tax benefit		(2.9	)
Impairment of investments		(2.1	)
Loss on derivative instruments		(0.2	)
Interest expense, less discount on long-term debt		40.1
Provision for income taxes, net of deferred taxes		0.6
EBITDA adjustment as allowed by the ABL Facility agreement		(2.5	)
Other adjustments as allowed by the ABL Facility agreement		7.4
Minimum consolidated EBITDA	$	110.5

If the borrowing availability is less than a minimum availability threshold determined in accordance with the ABL Facility agreement, we are then subject to additional financial ratio covenants. As of December 31, 2015, our borrowing availability was greater than the minimum availability threshold as follows (in millions):

	Amount		Minimum Availability Threshold
Availability (2)	$	64.1	$	23.8

(2) As of December 31, 2015, borrowing availability was calculated as a borrowing base of $148.5 million, less revolver borrowings of $57.5 million, less outstanding irrevocable letters of credit totaling $26.9 million, at which date no amount had been drawn.

As of December 31, 2015, our additional financial ratio covenants, as defined in the ABL Facility agreement (if they would have been applicable) were as follows:

Asset-Based Revolving Credit Facility Financial Ratio Covenants	Fiscal Year Ended December 31, 2015		Limits at December 31, 2015
Minimum fixed charge coverage ratio		1.81		1.00 Min.
Maximum consolidated first lien leverage ratio		0.55		2.00 Max.

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 from the ABL Facility 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.

In addition to the financial covenants described above, the ABL Facility agreement also contains a number of important customary affirmative and negative covenants which restrict, among other things, our ability to sell assets, incur additional debt, create liens, make investments, and pay dividends. As of December 31, 2015, we were in compliance with all covenants under the ABL Facility agreement. We do not believe that these restrictions impact our ability to meet future liquidity needs.

Tax-Exempt Financings

New York Bonds

In transition period 2014, we completed a financing transaction involving the issuance of $25.0 million in aggregate principal amount of New York Bonds. We borrowed the proceeds of the New York Bonds to repay borrowings under our Senior Credit Facility for qualifying property, plant and equipment assets purchased in the state of New York.

As of December 31, 2015, we had outstanding $25.0 million aggregate principal amount of New York Bonds. The New York Bonds, which are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 3.75% per annum through December 1, 2019, at which time they may be converted from a fixed rate to a variable rate, and interest is payable on June 1 and December 1 of each year. An additional $15.0 million aggregate principal amount of New York Bonds may be offered under the same indenture in the future. The New York Bonds mature on December 1, 2044.

Maine Bonds

As of December 31, 2015, we had outstanding $21.4 million aggregate principal amount of Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-2 (“FAME Bonds 2005R-2”). The FAME Bonds 2005R-2, which are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 6.25% per annum through January 31, 2017, at which time they may be converted from a fixed to a variable rate, and interest is payable semiannually in arrears on February 1 and August 1 of each year. The FAME Bonds 2005R-2 mature on January 1, 2025.

As of December 31, 2015, we had outstanding $3.6 million aggregate principal amount of Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-1 (“FAME Bonds 2005R-1”). The FAME Bonds 2005R-1 are variable rate bonds secured by a letter of credit issued by our administrative agent bank and interest is payable semiannually in arrears on February 1 and August 1 of each year. The FAME Bonds 2005R-1 mature on January 1, 2025. We borrowed the proceeds of the FAME Bonds 2005R-1 and 2005R-2 to pay for certain costs relating to the following: landfill development and construction; the acquisition of vehicles, containers and related equipment for solid waste collection and transportation services; improvements to existing solid waste disposal, hauling, transfer station and other facilities; other infrastructure improvements; and the acquisition of machinery and equipment for solid waste disposal operations owned and operated by us, or a related party, all located in Maine.

In fiscal year 2015, we completed a financing transaction involving the issuance of $15.0 million in aggregate principal amount of FAME Bonds 2015. We borrowed the proceeds of the offering of the FAME Bonds 2015 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 for the costs of the issuance of the FAME Bonds 2015. As of December 31, 2015, we had $1.3 million of restricted cash reserved for repayment of costs incurred to fund certain capital projects in the State of Maine as a result of this financing.

As of December 31, 2015, we had outstanding $15.0 million aggregate principal amount of FAME Bonds 2015. The FAME Bonds 2015, which are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 5.125% per annum through August 1, 2025, at which time they may be converted from a fixed to a variable rate, and interest is payable semiannually in arrears on February 1 and August 1 of each year. An additional $15.0 million aggregate principal amount of FAME Bonds 2015 may be offered under the same indenture in the future. The FAME Bonds 2015 mature on August 1, 2035.

Vermont Bonds

As of December 31, 2015, we had outstanding $16.0 million aggregate principal amount Vermont Economic Development Authority Solid Waste Disposal Long-Term Revenue Bonds Series 2013 (“Vermont Bonds”). The Vermont Bonds, which are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 4.75% per annum through April 1, 2018, at which time they may be converted from a fixed rate to a variable rate, and interest is payable semiannually in arrears on April 1 and October 1 of each year. The Vermont Bonds mature on April 1, 2036. We borrowed the proceeds of the Vermont Bonds to repay borrowings under our Senior Credit Facility for qualifying property, plant and equipment assets purchased in the state of Vermont.

65

New Hampshire Bonds

In transition period 2014, we completed a financing transaction involving the issuance of $11.0 million in aggregate principal amount of New Hampshire Bonds, consisting of the conversion and remarketing of $5.5 million principal amount New Hampshire Bonds from a variable rate to a fixed term rate and the issuance of an additional $5.5 million principal amount fixed term rate New Hampshire Bonds.

As of December 31, 2015, we had outstanding $11.0 million aggregate principal amount of New Hampshire Bonds. The New Hampshire Bonds, which are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 4.00% per annum through October 1, 2019, at which time they may be converted from a fixed rate to a variable rate, and interest is payable in arrears on April 1 and October 1 of each year. The New Hampshire Bonds mature on April 1, 2029. We borrowed the proceeds of the New Hampshire Bonds to repay borrowings under our Senior Credit Facility for qualifying property, plant and equipment assets purchased in the state of New Hampshire.

Senior Subordinated Notes

In fiscal year 2015, we issued an additional $60.0 million aggregate principal amount of 2019 Notes. The additional 2019 Notes, which are both fungible and issued under the same indenture as the $325.0 million 2019 Notes previously issued, were issued at a discount of $0.5 million to be accreted over the remaining term of the 2019 Notes. We used the net proceeds from this issuance, together with the initial borrowings under our new ABL Facility, to refinance our Senior Credit Facility. Additionally, in fiscal year 2015, we repurchased and permanently retired $14.7 million aggregate principal amount of 2019 Notes at a weighted average repurchase price of $101.0 in order to maximize interest savings by paying down our most expensive debt.

As of December 31, 2015, we had outstanding $370.3 million aggregate principal amount of 2019 Notes, which will mature on February 15, 2019. The 2019 Notes accrue interest at the rate of 7.75% per annum and interest is payable semiannually in arrears on February 15 and August 15 of each year. The 2019 Notes are fully and unconditionally guaranteed on a senior subordinated basis by substantially all of our existing and future domestic restricted subsidiaries that guarantee our ABL Facility.

The indenture governing the 2019 Notes contains certain negative covenants which restrict, among other things, our ability to sell assets, make investments in joint ventures, pay dividends, repurchase stock, incur debt, grant liens and issue preferred stock. As of December 31, 2015, we were in compliance with all covenants under the indenture governing the 2019 Notes, and we do not believe that these restrictions impact our ability to meet future liquidity needs except that they may impact our ability to increase our investments in non-wholly owned entities, including the joint ventures to which we are already party.

Shelf Registration

We have filed a universal shelf registration statement with the SEC pursuant to which we may from time to time issue securities in an amount of up to $190.0 million, after giving consideration to the $60.0 million aggregate principal amount of additional 2019 Notes we issued in February 2015 pursuant to this registration statement.

Contractual Obligations

The following table summarizes our significant contractual obligations and commitments as of December 31, 2015 (in thousands) and the anticipated effect of these obligations on our liquidity in future years:

	Less than one year		1 - 3 years		3 - 5 years		More than 5 years		Total
Long-term debt and capital leases	$	1,448	$	1,489	$	429,382	$	92,699	$	525,018
Interest obligations (1)		35,940		71,700		15,582		56,114		179,336
Non-cancellable operating leases (2)		17,591		35,792		29,737		117,224		200,344
Capping / closure / post-closure		732		3,399		11,577		113,691		129,399
Total contractual cash obligations (3)	$	55,711	$	112,380	$	486,278	$	379,728	$	1,034,097

(1) Based on debt and capital lease balances as of December 31, 2015. Interest obligations related to variable rate debt were calculated using variable rates in effect at December 31, 2015.

66

(2) Includes obligations related to landfill operating lease contracts.

(3) Contractual cash obligations do not include accounts payable or accrued liabilities, which will be paid in the fiscal year ending December 31, 2016.

In addition to the above obligations, we have unrecognized tax benefits at December 31, 2015 of approximately $0.4 million. Due to the uncertainty with respect to the timing of future cash flows associated with the unrecognized tax benefits at December 31, 2015, we are unable to make reasonably reliable estimates as to the timing of cash settlements. For a description of our commitments and contingencies, see Note 8, Final Capping, Closure and Post-Closure Costs, Note 10, Commitments and Contingencies and Note 14, Income Taxes, of our consolidated financial statements included in Item 8 of this Annual Report on Form 10-K.

Inflation

Although inflationary increases in costs have affected our historical operating margins, we believe that inflation generally has not had a significant impact on our operating results. 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 and oil recovery fee, 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 Conditions

Our business is primarily located in the northeastern United States. Therefore, our business, financial condition and results of operations are susceptible to downturns in the general economy in this geographic region and other factors affecting the region, such as state regulations and severe weather conditions. We are unable to forecast or determine the timing and/or the future impact of a sustained economic slowdown.

Limitations on Ownership of Notes

Pursuant to Section 2.19 of the indenture governing the 2019 Notes and the provisions of the FAME Bonds 2015, FAME Bonds 2005R-2, New Hampshire Bonds, New York Bonds and Vermont Bonds, no beneficial holder of the 2019 Notes, FAME Bonds 2015, FAME Bonds 2005R-2, New Hampshire Bonds, New York Bonds and/or Vermont Bonds is permitted to knowingly acquire 2019 Notes, FAME Bonds 2015, FAME Bonds 2005R-2, New Hampshire Bonds, New York Bonds and/or Vermont Bonds if such person would own 10% or more of the consolidated debt for which relevant subsidiaries of ours are obligated (and must dispose of 2019 Notes, FAME Bonds 2015, FAME Bonds 2005R-2, New Hampshire Bonds, New York Bonds and/or Vermont Bonds or other debt of ours to the extent such person becomes aware of exceeding such threshold), if such ownership would require consent of any regulatory authority under applicable law or regulation governing solid waste operators and such consent has not been obtained. We will furnish to the holders of the 2019 Notes, FAME Bonds 2015, FAME Bonds 2005R-2, New Hampshire Bonds, New York Bonds and Vermont Bonds, in each quarterly and annual report, the dollar amount of our debt that would serve as the threshold for evaluating a beneficial holder’s compliance with these ownership restrictions. As of December 31, 2015, that dollar amount was $51.6 million.

Critical Accounting Estimates and Assumptions

The preparation of our financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities, as applicable, at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. 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. 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 Accounting

Landfill Development Costs

We 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 our landfills, preparation costs include the total estimated costs to complete construction of the landfills’ permitted and expansion capacity.

Final Landfill Capping, Closure and Post-Closure Costs

The 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.

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, lawyers, accounting personnel and consultants, 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.

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;

68

• 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.

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 the measured density obtained from previous 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 the landfill 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.

Environmental Remediation Liabilities

We 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.

Accounts Receivable – Trade, Net of Allowance for Doubtful Accounts

Accounts receivable – trade represent receivables from customers for collection, transfer, recycling, disposal and other services. Our accounts receivable – trade 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 – trade, 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 trends, credit policy and a review of our accounts receivable – trade by aging category. Our reserve is evaluated and revised on a monthly basis. Past-due accounts receivable-trade are written off when deemed to be uncollectible.

Goodwill and Other Intangibles

We annually assess goodwill impairment at the end of our fiscal year or more frequently if events or circumstances indicate that impairment may exist. Historically, we have performed our annual goodwill impairment test using our fiscal year-end, or April 30^th, as the measurement date. Effective with the change in our fiscal year-end from April 30^th to December 31^st, we have voluntarily changed our goodwill impairment measurement date from April 30^th to December 31^st to coincide with the change in our fiscal year-end. The voluntary change in our goodwill impairment measurement date was applied prospectively as it represents the modification of an existing principle based on new facts and circumstances.

69

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 capitalization

If the fair value of the 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 in fiscal year 2015. As of December 31, 2015, the Step 1 testing for goodwill impairment performed for the 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 the Eastern, Western, Recycling and Customer Solutions reporting units exceeded its carrying value by in excess of 22.9%. We incurred no impairment of goodwill as a result of our annual goodwill impairment tests in fiscal year 2015 and transition period 2014. However, there can be no assurance that goodwill will not be impaired at any time in the future.

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.

Recovery 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 and equipment, and identifiable intangible 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;

70

• 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 3, Summary of Significant Accounting Policies and Note 16, Divestiture Transactions and Discontinued Operations to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for further disclosure.

Investments in Unconsolidated Entities

Investments 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. Additionally, 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 Costs

We are self-insured for vehicles and workers’ compensation with reinsurance coverage limiting our maximum exposure. Our maximum exposure in fiscal year 2015 under the workers’ compensation plan was $1.0 million per individual event. Our maximum exposure in fiscal year 2015 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.

See Note 3, Summary of Significant Accounting Policies to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for further disclosure.

Income Taxes

We 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.

See Note 14, Income Taxes to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for further disclosure.

Contingent Liabilities

We 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 4, Business Acquisitions for disclosure over a contingent liability assumed as part of the acquisition of a business.

See Note 4, Business Combinations and Note 10, 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 Compensation

All share-based compensation cost is measured at the grant date, based on the estimated fair value of the award, and is recognized as expense over the employee’s requisite service period. Stock-based compensation expense is based on the number of awards ultimately expected to vest and is therefore reduced for an estimate of the awards that are expected to be forfeited prior to vesting.

The fair value of each stock option 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 option holders will retain their vested stock options before exercising them and the estimated volatility of our common stock price over the expected term.

See Note 11, Stockholders Deficit to our consolidated financial statements included under Item 8 of this Annual Report on Form 10-K for further disclosure.

New Accounting Standards

For 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 RISK

In the normal course of business we are exposed to market risks, including changes in interest rates and certain commodity prices. We have a variety of strategies to mitigate these market risks, including at times using derivative instruments to hedge some portion of these risks.

Interest Rate Volatility

We had interest rate risk relating to approximately $61.0 million of long-term debt at December 31, 2015. The weighted average interest rate on the variable rate portion of long-term debt was approximately 2.9% at December 31, 2015. 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 increase or decrease by approximately $0.6 million. The remainder of our long-term debt is at fixed rates and not subject to interest rate risk.

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. As of December 31, 2015, we were currently party to one interest rate derivative agreement that is not deemed to be an effective cash flow hedge. The total notional amount of this agreement is $75.0 million and requires us to receive interest based on changes in LIBOR and pay interest at a rate of 1.45%. This agreement matures on March 15, 2016.

Commodity Price Volatility

Through 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 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 lower commodity price markets; (3) selling recycling commodities to out-bound MRF customers through floor price or fixed price agreements or (4) by entering into fixed price contracts and entering into hedges which 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, 2015, we were not party to any commodity hedging agreements.

Should commodity prices change by 10%, we estimate that our annual operating income margin would change by approximately $0.8 million. 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 estimated ranges of operating income impact may not be indicative of future operating results and actual results may vary materially.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders

of Casella Waste Systems, Inc.:

We have audited the accompanying consolidated balance sheets of Casella Waste Systems, Inc. and subsidiaries (the “Company”) as of December 31, 2015, December 31, 2014 and April 30, 2014, and the related consolidated statements of operations, comprehensive loss, stockholders’ (deficit) equity and cash flows for the fiscal year ended December 31, 2015, the eight months ended December 31, 2014, and for the fiscal years ended April 30, 2014 and April 30, 2013. Our audits also included the financial statement schedules of Casella Waste Systems, Inc. and subsidiaries listed in Item 15(a)(2). We also have audited the Company’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. The Company’s management is responsible for these financial statements and financial statement schedules, 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 these financial statements and schedules and an opinion on the Company’s internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. 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.

A 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 (a) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (b) 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 (c) 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.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Casella Waste Systems, Inc. and subsidiaries as of December 31, 2015, December 31, 2014 and April 30, 2014, and the results of their operations and their cash flows for the fiscal year ended December 31, 2015, the eight months ended December 31, 2014, and the fiscal years ended April 30, 2014 and April 30, 2013, in conformity with accounting principles generally accepted in the United States of America, and in our opinion, the related financial statement schedules, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly in all material respects the information set forth therein. Also in our opinion, Casella Waste Systems, Inc. and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except for per share data)

1. BASIS OF PRESENTATION

Casella Waste Systems, Inc. (“Parent”), and its consolidated subsidiaries (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, the 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, major account and industrial services, discontinued operations and earnings from equity method investees, as applicable, are included in our Other segment.

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.

For comparative purposes, certain prior period amounts in the consolidated statements of operations have been reclassified to confirm to the current fiscal year presentation. The reclassifications had no effect on the previously reported results of operations or retained earnings.

2. ACCOUNTING CHANGES

Adoption of New Accounting Pronouncements

Income Taxes

In November 2015, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update for the accounting for deferred income taxes. The update provides that deferred tax liabilities and assets be classified as noncurrent amounts in a classified statement of financial position. This guidance is effective prospectively or retrospectively for annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2016, with early adoption permitted. We adopted this guidance effective December 31, 2015 in order to simplify the presentation of deferred income taxes. This guidance impacts the balance sheet presentation of our deferred tax liabilities and assets. Prior periods were not retrospectively adjusted.

Discontinued Operations

In April 2014, the FASB issued an accounting standards update for the requirements of reporting discontinued operations. The update provides that an entity, a group of components of an entity, or a business is required to be reported in discontinued operations once it meets the held for sale criteria, is disposed of by sale, or is disposed of other than by sale only if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. The update also requires that additional disclosures about discontinued operations be made. This guidance is effective prospectively for annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2014. We adopted this guidance effective January 1, 2015 with no impact on our consolidated financial position or results of operations.

83

New Accounting Pronouncements Pending Adoption

Business Combinations

In September 2015, the FASB issued an accounting standards update for the accounting of measurement-period adjustments in business combinations. The update provides that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined as if the accounting had been completed at the acquisition date. This includes the acquirer presenting separately on the face of the income statement or disclosing in the notes thereto the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. This guidance is effective for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted. We expect that this guidance will have no impact on our consolidated financial position or results of operations upon adoption.

Debt Issuance Costs

In April 2015, the FASB issued an accounting standards update for the presentation of debt issuance costs. The update provides that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability. This guidance is effective on a retrospective basis for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted. This guidance will impact the balance sheet presentation of our debt issuance costs and related debt liabilities upon adoption.

Consolidation

In February 2015, the FASB issued an accounting standards update for the requirements of consolidation. The update provides changes to the analysis that an entity must perform to determine whether it should consolidate certain types of legal entities because in certain situations deconsolidated financial statements are necessary to better analyze the reporting entity’s economic and operational results. This guidance is effective for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We are currently assessing the potential impact this guidance may have on our consolidated financial statements as a result of adopting this standard.

Extraordinary and Unusual Items

In January 2015, the FASB issued an accounting standards update that eliminates the GAAP concept of extraordinary items. The update provides for the elimination of the requirements to consider whether an underlying event or transaction is extraordinary, but retains the presentation and disclosure guidance for items that are unusual in nature or occur infrequently and expands upon it to include items that are both unusual in nature and infrequently occurring. This guidance is effective prospectively or retrospectively for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We expect that this guidance will have no impact on our consolidated financial position or results of operations upon adoption.

Revenue Recognition

In May 2014, the FASB issued an accounting standards update for the recognition of revenue, which supersedes existing revenue recognition requirements and most industry-specific guidance. The update provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective for annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2017 under either full or modified retrospective adoption. Early application is permitted only as of annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2016. We are currently assessing the potential impact this guidance may have on our consolidated financial statements as a result of adopting this standard.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Management’s Estimates and Assumptions

Preparation of our consolidated financial statements in accordance with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the accounting for and recognition and disclosure of assets, liabilities, equity, revenues and expenses. We must make these estimates and assumptions because certain information that we use is dependent on future events, cannot be calculated with a high degree of precision given the available data or simply cannot be readily calculated. In

84

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 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. In the opinion of management, these consolidated financial statements include all adjustments, which include normal recurring and nonrecurring adjustments, necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented. Actual results may differ materially from the estimates and assumptions that we use in the preparation of our consolidated financial statements.

Change in Fiscal Year

In June 2014, we elected to change our fiscal year-end from April 30^th to December 31^st. This change in fiscal year became effective for our fiscal year beginning January 1, 2015 and ended December 31, 2015. As a result of this change, we filed a Transition Report on Form 10-KT for the eight-month transition period ended December 31, 2014. The references in these notes to the consolidated financial statements to the terms below reflect the respective reporting periods presented in the consolidated financial statements:

Term	Financial Reporting Period
fiscal year 2015	January 1, 2015 through December 31, 2015
transition period 2014	May 1, 2014 through December 31, 2014
fiscal year 2014	May 1, 2013 through April 30, 2014
fiscal year 2013	May 1, 2012 through April 30, 2013

Cash and Cash Equivalents

We consider all highly liquid investments purchased with original maturities of three months or less to be cash equivalents.

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents, restricted cash, accounts receivable-trade and derivative instruments. We maintain cash and cash equivalents and restricted cash 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-trade is limited because our customer base is comprised of a large number of geographically diverse customers, thus reducing the credit risk associated with any one customer group. As of December 31, 2015 no single customer or customer group represented greater than 5% of total accounts receivable-trade. We manage credit risk through credit evaluations, credit limits, monitoring procedures and, at times, credit insurance, but generally do not require collateral to support accounts receivable -trade. 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 – Trade, Net of Allowance for Doubtful Accounts

Accounts receivable – trade represent receivables from customers for collection, transfer, recycling, disposal and other services. Our accounts receivable – trade 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 – trade, 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 trends, credit policy and a review of our accounts receivable – trade by aging category. Our reserve is evaluated and revised on a monthly basis. Past-due accounts receivable-trade are written off when deemed to be uncollectible. As of December 31, 2015, $44,707 of our accounts receivable – trade served as eligible collateral under our senior secured asset-based revolving credit and letter of credit facility (“ABL Facility”).

Inventory

Inventory 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. As of December 31, 2015, $219 of our recyclables ready for sale served as eligible collateral under our ABL Facility.

85

Property, Plant and Equipment

Property, 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 Classification	Estimated Useful Life
Buildings and improvements		10-30 years
Machinery and equipment		5-10 years
Rolling stock		5-10 years
Containers		5-12 years
Furniture and Fixtures		3-8 years

The 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 disclosure over the amortization of landfill development costs and Note 6, Property, Plant and Equipment for disclosure over property, plant and equipment.

Landfill Accounting

Life Cycle Accounting

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 our landfills, preparation costs include the total estimated costs to complete construction of the landfills’ permitted and expansion capacity.

Landfill Development Costs

We 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 fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013 was $62, $333, $256 and $368, respectively.

Landfill Airspace

We 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.

86

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.

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 the measured density obtained from previous 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 the landfill 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 Costs

The 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.

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, lawyers, accounting personnel and consultants, 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 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,

87

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 (2.0% as of December 31, 2015). 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, 2015 is between approximately 9.1% and 9.5%, 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 $3,370, $2,275, $3,967 and $3,538 in fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, 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 8, Final Capping, Closure and Post-Closure Costs for disclosure over final capping, closure and post-closure costs asset retirement obligations.

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 cash. Surety bonds securing closure and post-closure obligations at December 31, 2015, December 31, 2014 and April 30, 2014 totaled $156,163, $144,633 and 133,847, respectively. Letters of credit securing closure and post-closure obligations as of December 31, 2015, December 31, 2014 and April 30, 2014 totaled $1,000, $1,104 and $1,104, respectively. See Note 5, Restricted Cash / Restricted Assets for disclosure over restricted cash securing closure and post-closure obligations.

Landfill Operating Lease Contracts

We entered into three landfill operation and management agreements in the fiscal year ended April 30, 2004 and one landfill operation and management agreement in the fiscal year ended April 30, 2006. 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 liabilities. 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 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. See Note 6, Property, Plant and Equipment for disclosure over depletion of landfill operating lease contracts.

Leases

We lease property and equipment in the ordinary course of our business. Our most significant lease obligations are for property and equipment specific to our industry. Our leases have varying terms. Some may include renewal or purchase options, escalation clauses, restrictions, lease concessions, capital project funding, penalties or other obligations that we consider in determining minimum rental payments. Leases are classified as either operating leases or capital leases, as appropriate.

Operating Leases. Many of our leases are operating leases. This classification generally can be attributed to either (i) relatively low fixed minimum rental payments or (2) minimum lease terms that are much shorter than the assets’ economic useful lives. We expect that, in the normal course of business, our operating leases will be replaced by other leases, or replaced with fixed asset expenditures. See Note 10, Commitments and Contingencies for disclosure over future minimum lease payments related to our operating leases.

Capital Leases. We capitalize assets acquired under capital leases at the inception of each lease and amortize them to depreciation expense over the lesser of the useful life of the asset or the lease term, as appropriate. The present value of the related lease payments is recorded as a debt obligation. See Note 9, Long-Term Debt and Capital Leases for disclosure over our future maturities of debt, which includes capital lease payments.

88

Goodwill and Intangible Assets

Goodwill. 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 7, 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 7, Goodwill and Intangible Assets for disclosure over intangible assets.

Investments in Unconsolidated Entities

Investments 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, 2015, December 31, 2014 and April 30, 2014, we had no investments accounted for under the equity 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. Additionally, 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. See “Asset Impairments” accounting policy below and Note 12, Fair Value of Financial Instruments for further disclosure over our investments.

Equity Method Investments

GreenFiber. In the fiscal year ended April 30, 2001, we entered into a joint venture agreement with Louisiana-Pacific Corporation (“LP”) to combine our respective cellulose insulation businesses into a single operating entity, US GreenFiber LLC (“GreenFiber”). In fiscal year 2014, we and LP executed a purchase and sale agreement with a limited liability company formed by Tenex Capital Partners, L.P., pursuant to which we and LP agreed to sell our membership interests in GreenFiber for total cash consideration of $18,000 plus an expected working capital true up less any indebtedness and other unpaid transaction costs of GreenFiber as of the closing date. The transaction was completed in fiscal year 2014 for $19,194 in gross cash proceeds, including a $1,194 working capital adjustment. After netting indebtedness of GreenFiber and transaction costs, our portion of the net cash proceeds based on our 50% membership interest amounted to $3,442. After considering the $593 impact of our unrealized losses relating to derivative instruments in accumulated other comprehensive loss on our investment in GreenFiber, we recorded a gain on sale of equity method investment of $593 in fiscal year 2014. We had previously accounted for our 50% membership interest in GreenFiber using the equity method of accounting.

Tompkins. In the fiscal year ended April 30, 2012, we finalized the terms of a joint venture agreement with FCR, LLC (“FCR”) to form Tompkins County Recycling LLC (“Tompkins”), a joint venture that operates a material recovery facility (“MRF”) located in Tompkins County, New York and processes and sells commodities delivered to the Tompkins MRF. In fiscal year 2014, we purchased the remaining 50% membership interest of Tompkins for total cash consideration of $425. The acquisition-date fair value of our investment in Tompkins, which was determined using the cost approach based on an assessment of the price to purchase the acquired assets of Tompkins, prior to the acquisition date was $300. We recognized a $106 gain through loss from equity method investments due to the remeasurement in fiscal year 2014. As a result of the purchase, we no longer account for our investment in Tompkins using the equity method of accounting and began including the results of Tompkins in our consolidated financial statements.

89

Fair Value of Financial Instruments

Our financial instruments include cash and cash equivalents, accounts receivable-trade, restricted cash and investments held in trust on deposit with various banks as collateral for our obligations relative to our landfill final capping, closure and post-closure costs and 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 9, Long-Term Debt and Capital Leases and Note 12, 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 Combinations

We 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 4, Business Combinations for disclosure over business acquisitions.

Environmental Remediation Liabilities

We 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 10, Commitments and Contingencies for disclosure over environmental remediation liabilities.

Self-Insurance Liabilities and Related Costs

We are self-insured for vehicles and workers’ compensation with reinsurance coverage limiting our maximum exposure. Our maximum exposure in fiscal year 2015 under the workers’ compensation plan is $1,000 per individual event. Our maximum exposure in fiscal year 2015 under the automobile plan is $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 actuarially determined liability is calculated based on historical data, which considers both the frequency and settlement amount of claims. Our self-insurance reserves totaled $11,560, $10,863 and $10,280 as of December 31, 2015, December 31, 2014 and April 30, 2014, 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.

90

Income Taxes

We 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. See Note 14, Income Taxes for disclosure related to income taxes.

Derivatives and Hedging

We 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 also 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 effective cash flow hedges, the change in the fair value of these derivatives is recorded in our stockholders’ equity (deficit) as a component of accumulated other comprehensive income (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 are 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, 2015.

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 effective cash flow hedges, the change in fair value is recorded in our stockholders’ equity (deficit) as a component of accumulated other comprehensive income (loss) and included in interest expense at the same time as interest expense is affected by the hedged transaction. Differences paid or received over the life of the agreements are recorded as additions to or reductions of interest expense on the underlying debt. We were not party to any interest rate derivative agreements deemed to be effective cash flow hedges as of December 31, 2015.

For interest rate derivatives deemed to be ineffective cash flow hedges, the change in fair value is recorded through earnings and included in loss (gain) on derivative instruments. We are currently party to one interest rate swap deemed to be an ineffective cash flow hedge that is scheduled to mature on March 15, 2016 and were party to another interest rate swap deemed to be an ineffective cash flow hedge that was settled in fiscal year 2015 for $830 in conjunction with the refinancing of our senior revolving credit and letter of credit facility that was due March 18, 2016 (“Senior Credit Facility”). See Note 12, Fair Value of Financial Instruments for fair value disclosure over derivative instruments.

Contingent Liabilities

We 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

91

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 10, Commitments and Contingencies for disclosure over loss contingencies. 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 4, Business Combinations for disclosure over a contingent liability assumed as part of the acquisition of a business.

Revenue Recognition

We recognize collection, transfer, recycling and disposal revenues as the services are provided. Certain customers are billed in advance and, accordingly, recognition of the related revenues is deferred until the services are provided.

Revenues from the sale of recycled materials are recognized upon shipment. Rebates to certain municipalities based on sales of recyclable materials are recorded upon the sale of such recyclables to third-parties and are included as a reduction of revenues. Revenues for processing of recyclable materials are recognized when the related service is provided. Revenues from the brokerage of recycled materials are recognized on a net basis at the time of shipment.

Asset Impairments

Recovery 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, and identifiable intangible 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.

92

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 15, Other Items and Charges for disclosure related to long-lived asset impairments recognized during the reporting periods.

Goodwill. We annually assess goodwill impairment at the end of our fiscal year or more frequently if events or circumstances indicate that impairment may exist. Historically, we have performed our annual goodwill impairment test using our fiscal year-end, or April 30^th, as the measurement date. Effective with the change in our fiscal year-end from April 30^th to December 31^st, we have voluntarily changed our goodwill impairment measurement date from April 30^th to December 31^st to coincide with the change in our fiscal year-end. The voluntary change in our goodwill impairment measurement date was applied prospectively as it represents the modification of an existing principle based on new facts and circumstances.

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 capitalization.

If the fair value of the 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 in fiscal year 2015. As of December 31, 2015, the Step 1 testing for goodwill impairment performed for the Eastern, Western, Recycling and Customer Solutions reporting

93

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 the Eastern, Western, Recycling and Customer Solutions reporting units exceeded its carrying value by in excess of 22.9%. We incurred no impairment of goodwill as a result of our annual goodwill impairment tests in fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013. However, there can be no assurance that goodwill will not be impaired at any time in the future.

Cost Method Investments. As of December 31, 2015, we owned 5.3% of the outstanding common stock of Recycle Rewards, Inc. (“Recycle Rewards”), a company that markets an incentive based recycling service. In both fiscal year 2015 and transition period 2014, 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 2015, and had a valuation analysis performed by a third-party valuation specialist in transition period 2014, both of 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 these analyses, it was determined in each case that the fair value of our cost method investment in Recycle Rewards was less than the carrying amount and, therefore, we recorded other-than-temporary investment impairment charges of $1,090 and $2,320 in fiscal year 2015 and transition period 2014, respectively. As of December 31, 2015, the carrying amount of our cost method investment in Recycle Rewards was $1,070.

As of December 31, 2015, we owned 9.8% of the outstanding equity value of GreenerU, Inc. (“GreenerU”), a services company focused on providing energy efficiency, sustainability and renewable energy solutions to colleges and universities. In fiscal year 2015, it was determined based on the operating performance and recent indications of third-party interest in GreenerU that our cost method investment in GreenerU was potentially impaired. A valuation analysis was performed by a third-party valuation specialist using a market approach based on an option pricing methodology to determine an equity value and fair market value per share for GreenerU. Based on this analysis, it was determined that the fair value of our cost method investment in GreenerU was less than the carrying amount and, therefore, we recorded an other-than-temporary investment impairment charge of $691 in fiscal year 2015. As of December 31, 2015, the carrying amount of our cost method investment in GreenerU was $309.

As of December 31, 2015, we owned 17.0% and 16.2% of the outstanding common stock of AGreen Energy LLC (“AGreen”) and BGreen Energy LLC (“BGreen”), respectively. In fiscal year 2015, AGreen and BGreen, both of which we account for as cost method investments, entered into agreements that resulted in the contribution and sale of certain assets and liabilities of AGreen and BGreen to a limited liability company in exchange for partial ownership interests in a parent of that limited liability company. As a result of the transactions, we performed an analysis to determine whether an other-than-temporary impairment in the carrying value of our cost method investments had occurred. Based on the analysis performed, which measured the fair value of our cost method investments using an in-exchange valuation premise under the market approach that utilized the estimated purchase consideration received, we recorded an investment impairment charge of $318 in fiscal year 2015. As of December 31, 2015, the carrying amount of our cost method investment in AGreen and BGreen was $297.

Stock-Based Compensation

All 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. Stock-based compensation expense is based on the number of awards ultimately expected to vest and is therefore reduced for an estimate of the awards that are expected to be forfeited prior to vesting.

The fair value of each stock option 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 option holders will retain their vested stock options before exercising them and the estimated volatility of our common stock price over the expected term.

See Note 11, Stockholders Deficit for disclosure over stock-based compensation.

Earnings per Share

Basic earnings per share is computed by dividing the net loss from continuing operations attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated based on the combined weighted average number of common shares and potentially dilutive shares, which include, where appropriate, the assumed exercise of employee stock options, unvested restricted stock awards, unvested restricted stock units and unvested performance stock units. In computing diluted earnings per share, we utilize the treasury stock method. See Note 17, Earnings Per Share for disclosure over the calculation of earnings per share.

94

Discontinued Operations

We analyze our operations that have been divested or classified as held-for-sale to determine if they qualify for discontinued operations accounting. A component of an entity, a group of components of an entity, or a business is required to be reported in discontinued operations once it meets the held for sale criteria, is disposed of by sale, or is disposed of other than by sale. A disposal is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. See Note 16, Divestiture Transactions and Discontinued Operations for disclosure over discontinued operations.

Subsequent Events

Except as disclosed, no material subsequent events have occurred since December 31, 2015 through the date of this filing that would require recognition or disclosure in our current period consolidated financial statements.

4. BUSINESS COMBINATIONS

We acquired various businesses during transition period 2014, fiscal year 2014 and fiscal year 2013, including several solid waste hauling operations, a transfer station, a MRF and an industrial service management business (included in the Other segment). 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, except amounts related to the acquisition of Bestway Disposal Services and BBI Waste Services (“BBI”) in fiscal year 2013, are expected to be deductible for tax purposes. See Note 14, Income Taxes for disclosure over the tax impact associated with the acquisition of BBI. We did not acquire any businesses during fiscal year 2015.

The purchase price paid for these acquisitions and the allocation of the purchase price is as follows:

	Eight Months Ended December 31, 2014		Fiscal Years Ended April 30,
			2014			2013

Excess purchase price to be allocated to goodwill	$	31	$	3,183		$	14,222

(1) In fiscal year 2014, we recovered a portion of the purchase price holdback amount we had previously paid and were relieved of any potential contingent consideration obligation associated with the acquisition of an industrial service management business completed earlier in fiscal year 2014. As a result, we recorded a $1,058 gain on settlement of acquisition related contingent consideration in fiscal year 2014.

8. FINAL CAPPING, CLOSURE AND POST-CLOSURE COSTS

Accrued final capping, closure and post-closure costs include the current and non-current portion of costs associated with obligations for final capping closure and post-closure of our landfills. We estimate our future final capping, closure and post-closure costs in order to determine the final capping, closure and post-closure expense per ton of waste placed into each landfill as further described in Note 3, Summary of Significant Accounting Policies to these consolidated financial statements. The anticipated timeframe 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 changes to accrued final capping, closure and post-closure liabilities are as follows:

ABL Facility

In fiscal year 2015, we issued an additional $60,000 aggregate principal amount of 7.75% senior subordinated notes due February 15, 2019 (“2019 Notes”). The additional 2019 Notes, which are fungible with and issued under the same indenture as the $325,000 2019 Notes previously issued, were issued at a discount of approximately $476 to be accreted over the remaining term of the 2019 Notes. We used the net proceeds from this issuance, together with the initial borrowings under our new ABL Facility, to refinance our Senior Credit Facility.

Our ABL Facility consists of a revolving credit facility with loans thereunder being available up to an aggregate principal amount of $190,000, subject to availability under a borrowing base formula as defined in the ABL Facility agreement. We have the right to request, at our discretion, an increase in the amount of loans under the ABL Facility by an aggregate amount of $100,000, subject to the terms and conditions set forth in the ABL Facility agreement. Interest accrues at one month LIBOR plus between 1.75% and 2.50%, subject to the terms of the ABL Facility agreement and is set at LIBOR plus 2.25% as of December 31, 2015. The ABL Facility matures on February 26, 2020. If we fail to refinance the 2019 Notes on or before November 16, 2018, the maturity date for the ABL Facility will be November 16, 2018. The ABL Facility is guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries and is collateralized by certain qualified accounts receivable, trade, inventory and property, plant and equipment. As of December 31, 2015, our borrowing availability under the ABL Facility was $64,112 and was calculated as a borrowing base of $148,473, less revolver borrowings of $57,422, less outstanding irrevocable letters of credit totaling $26,939, at which date no amount had been drawn.

The ABL Facility requires us to maintain a certain minimum consolidated EBITDA measured at the end of each fiscal quarter. Additionally, if borrowing availability does not meet certain thresholds as defined in the ABL Facility agreement, the ABL Facility requires us to meet additional covenants, including, without limitation:

• a minimum fixed charge coverage ratio; and

• a maximum consolidated first lien funded debt to consolidated EBITDA ratio.

99

An event of default under any of our debt agreements could permit some of our lenders, including the lenders under the ABL 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 ABL 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 Financings

New York Bonds. In transition period 2014, we completed a financing transaction involving $25,000 in aggregate principal amount of New York State Environmental Facilities Corporation Solid Waste Disposal Revenue Bonds Series 2014 (“New York Bonds”).

During the fixed interest rate period, the Vermont Bonds will not be supported by a letter of credit. Interest is payable semiannually in arrears on April 1 and October 1 of each year. The Vermont Bonds mature on April 1, 2036. We borrowed the proceeds of the Vermont Bonds to repay borrowings under our Senior Credit Facility for qualifying property, plant and equipment assets purchased in the state of Vermont.

New Hampshire Bonds. In transition period 2014, we completed a financing transaction involving $11,000 aggregate principal amount of tax-exempt Solid Waste Disposal Revenue Bonds Series 2013 issued by the Business Finance Authority of the State of New Hampshire (“New Hampshire Bonds”), consisting of the conversion and remarketing of $5,500 principal amount New Hampshire Bonds from a variable rate to a fixed term rate and the issuance of an additional $5,500 principal amount fixed term rate New Hampshire Bonds.

As of December 31, 2015, we had outstanding $11,000 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 4.00% per annum through October 1, 2019, at which time they may be converted from a fixed rate to a variable rate. During the fixed interest rate period, the New Hampshire Bonds will not be supported by a letter of credit. Interest is payable in arrears on April 1 and October 1 of each year. The New Hampshire Bonds mature on April 1, 2029. We borrowed the proceeds of the New Hampshire Bonds to repay borrowings under our Senior Credit Facility for qualifying property, plant and equipment assets purchased in the state of New Hampshire.

Senior Subordinated Notes

In fiscal year 2015, we issued an additional $60,000 aggregate principal amount of 2019 Notes. The additional 2019 Notes, which are both fungible and issued under the same indenture as the $325,000 2019 Notes previously issued, were issued at a discount of $476 to be accreted over the remaining term of the 2019 Notes. We used the net proceeds from this issuance, together with the initial borrowings under our new ABL Facility, to refinance our Senior Credit Facility. Additionally, in fiscal year 2015 we repurchased and permanently retired $14,700 aggregate principal amount of 2019 Notes at a weighted average repurchase price of $101.0 in order to maximize interest savings by paying down our most expensive debt.

As of December 31, 2015, we had outstanding $370,300 aggregate principal amount of 2019 Notes, which will mature on February 15, 2019. The 2019 Notes accrue interest at the rate of 7.75% per annum and interest is payable semiannually in arrears on February 15 and August 15 of each year. The 2019 Notes are fully and unconditionally guaranteed on a senior subordinated basis by substantially all of our existing and future domestic restricted subsidiaries that guarantee our ABL Facility.

The indenture governing the 2019 Notes contains certain negative covenants which restrict, among other things, our ability to sell assets, make investments in joint ventures, pay dividends, repurchase stock, incur debt, grant liens and issue preferred stock. As of December 31, 2015, we were in compliance with all covenants under the indenture governing the 2019 Notes, and we do not believe that these restrictions impact our ability to meet future liquidity needs except that they may impact our ability to increase our investments in non-wholly owned entities, including the joint ventures to which we are already party.

Loss on Debt Extinguishment

Senior Subordinated Notes. In fiscal year 2015, we repurchased and permanently retired $14,700 aggregate principal amount of 2019 Notes at a weighted average repurchase price of $101.0 in order to maximize interest savings by paying down our most expensive debt. As a result of the repurchase, we recorded a charge of $478 in fiscal year 2015 as a loss on debt extinguishment primarily related to the non-cash write off of deferred financing costs and unamortized original issue discount in proportion with the settlement amount.

Senior Credit Facility. In fiscal year 2015, we recorded a charge of $521 as a loss on debt extinguishment related to the write-off of deferred financing costs in connection with changes to the borrowing capacity from the Senior Credit Facility to the ABL Facility. The remaining unamortized deferred financing costs of the Senior Credit Facility, along with fees paid to the creditor and third-party costs incurred for the ABL Facility, are to be amortized over the term of the ABL Facility.

Second Lien Notes. In fiscal year 2013, we recorded a charge of $15,584 as a loss on debt extinguishment related to the full refinancing of our 11.0% senior second lien notes (“Second Lien Notes”). The loss on debt extinguishment consisted of a $2,767 non-cash write off of deferred financing costs, a $2,074 non-cash write off of the unamortized original issue discount and a $10,743 charge associated with the early tender premium and tender fees associated with the redemption of the Second Lien Notes.

Total interest expense	$	40,420		$	25,639		$	38,175		$	41,570

Fair Value of Debt

As of December 31, 2015, the fair value of our fixed rate debt, including our 2019 Notes, FAME Bonds 2005R-2, FAME Bonds 2015, Vermont Bonds, New York Bonds and New Hampshire Bonds was approximately $458,775 and the carrying value was $458,700. The fair value of the 2019 Notes are considered to be Level 1 within the fair value hierarchy as the fair value is based off of a quoted market price in an active market. The fair value of the FAME Bonds 2005R-2, the FAME Bonds 2015, the Vermont Bonds, the New York Bonds and the New Hampshire Bonds is considered to be Level 2 within the fair value hierarchy as the fair value is determined using market approach pricing provided by a third-party that utilizes pricing models and pricing systems, mathematical tools and judgment to determine the evaluated price for the security based on the market information of each of the bonds or securities with similar characteristics.

Although we have determined the estimated fair value amounts of the FAME Bonds 2005R-2, the FAME Bonds 2015, the Vermont Bonds, the New York Bonds and the 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. As of December 31, 2015, the fair value of our ABL Facility approximated its carrying value of $57,422 based on current borrowing rates for similar types of borrowing arrangements, or Level 2 inputs. The carrying value of our remaining material variable rate debt, the FAME Bonds 2005R-1, approximates fair value because the interest rate for the debt instrument is based on a market index that approximates current market rates for instruments with similar risk and maturities.

Future Maturities of Debt

Aggregate principal maturities of long-term debt and capital leases are as follows:

10. COMMITMENTS AND CONTINGENCIES

Lease Commitments

We lease operating facilities and equipment in the ordinary course of our business under various operating leases with monthly payments varying up to $36. Future minimum rental payments are recognized on a straight-line basis over the minimum lease term. Total rent expense under operating leases charged to operations was $9,392, $4,868, $5,651 and $5,372 in fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, respectively.

Future minimum rental payments under non-cancellable operating leases, which include landfill operating leases, are as follows:

Estimated Future Minimum Lease Payments as of December 31, 2015:
2016	$	17,591
2017		17,838
2018		17,954
2019		16,519
2020		13,218
Thereafter		117,224
Total minimum lease payments	$	200,344

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 alleging environmental damage or violations of the permits and licenses pursuant to which we operate. In addition, we have been 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 Accounting Standards Codification (“ASC”) 450-20, 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.

Expera Old Town, LLC v. Casella Waste Systems, Inc.

On or about November 6, 2015, Expera Old Town, LLC (“Expera”) filed a lawsuit against us in Maine Superior Court, seeking damages for breach of contract and unjust enrichment, and an action for declaratory judgment (the “Lawsuit”). Expera was a successor-in-interest to a contract between us and Old Town Fuel and Fiber (“OTFF”), the former owner of a pulp manufacturing facility (“Facility”) located in Old Town, Maine (the “Contract”). Expera purchased the Facility during the pendency of the bankruptcy of OTFF. Since the filing of the Lawsuit, Expera has sold the Facility and related assets, to MFGR LLC (“MFGR”). MFGR continues to allege that we have the obligation to provide a specialized type of wood fuel to the Facility or, alternatively, that we owe a “Fuel Replacement Fee” of up to $2,000 a year (subject to the possibility of certain credits against such payments). The Contract expires in 2036. We believe we have meritorious defenses to each of the claims in the Lawsuit, are vigorously contesting these allegations, and have filed a counter claim for funds owed to us by MFGR or Expera.

On or about February 10, 2016, we reached an agreement in principle with MFGR to dismiss this suit with prejudice, and to resolve all outstanding claims of any nature including future claims which could arise under the Contract. The Parties are endeavoring in good faith to enter into a settlement agreement (“SA”) and ancillary agreements. Pursuant to the pending SA, we will pay MFGR $1,250 upon execution of the SA, and $350 a year for five years following execution of the SA. Accordingly, taking into account the net present value of the settlement payments, we have recorded a reserve of $2,616 as of December 31, 2015. This includes a contract settlement charge of $1,940 and $676 of operating expenses recorded in fiscal year 2015. We also reserved $75 as of December 31, 2015 for legal costs associated with the Lawsuit and SA.

We will also enter into a new leachate disposal agreement at market prices with MFGR for the treatment of leachate from the landfill managed by us for the State of Maine located in Old Town, Maine (“Juniper Ridge”), and MFGR will enter into a waste disposal agreement at market prices with us for the disposal at the Juniper Ridge of waste materials produced in the demolition or re-purposing of the Facility.

Greenwood Street Landfill, Worcester, Massachusetts

On July 2, 2014, we received a draft Administrative Consent Order with Penalty and Notice of Noncompliance (“Draft Order”) from the Massachusetts Department of Environmental Protection (“MADEP”) alleging that a subsidiary, NEWS of Worcester, LLC, had completed substantive closure of a portion of the Greenwood Street Landfill in Worcester, Massachusetts in 2010, at an elevation exceeding the applicable permit condition. While we neither admitted nor denied the allegations in the Draft Order, a final Administrative Consent Order with Penalty and Notice of Noncompliance was executed on March 20, 2015 (“Final Order”), and we agreed to pay a civil administrative penalty in a total amount of $172. MADEP agreed that $129 of that amount could be paid as a Supplemental Environmental Project (“SEP”) for work being done by the Massachusetts Audubon Society at the Broad Meadow Brook Conservation Center & Wildlife Sanctuary in Worcester, Massachusetts. This SEP has been paid in full.

Environmental Remediation Liability

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 matter represents our outstanding material claim.

Potsdam Environmental Remediation Liability

On December 20, 2000, the State of New York Department of Environmental Conservation (“DEC”) issued an Order on Consent (“Order”) which named Waste-Stream, Inc. (“WSI”), our subsidiary, General Motors Corporation (“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 15% participant share. It is unlikely that any significant expenditures relating to onsite remediation will be incurred until the fiscal year ending December 31, 2017. 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 1.8%. The changes to the environmental remediation liability associated with the Potsdam environmental remediation liability are as follows:

	Fiscal Year Ended		Eight Months Ended			Fiscal Year Ended
	December 31, 2015		December 31, 2014			April 30, 2014
Beginning balance	$	5,142	$	5,320		$	5,297
Obligations incurred		—		—			31
Revisions in estimates (1)		—		—			(118	)
Accretion expense		79		92			138
Payments		—		(270	)		(28	)
Ending balance	$	5,221	$	5,142		$	5,320

104

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:

Estimated Future Environmental Remediation Payments as of December 31, 2015:
2016	$	273
2017		3,256
2018		855
2019		40
2020		25
Thereafter		749
Total	$	5,198

A 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	$	5,198
Plus inflation		23
Liability balance - December 31, 2015	$	5,221

Any 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.

Employment Contracts

We have entered into employment contracts with four of our executive officers. The contracts are dated June 18, 2001, March 31, 2006, July 6, 2010 and September 1, 2012. 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 $1,425. 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.

11. STOCKHOLDERS’ DEFICIT

Common Stock

The 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.

In fiscal year 2013, we sold 11,500 shares of Class A common stock at an average price of $4.00 per share in a registered public offering. The net proceeds received from the registered public offering, after deducting underwriting discounts, commissions and offering expenses, were $42,184 and were used to refinance our Second Lien Notes.

105

Preferred Stock

We are authorized to issue up to 944 shares of preferred stock in one or more series. As of December 31, 2015 and December 31, 2014 we had no shares issued.

Stock Based Compensation

Stock Incentive Plans

1997 Stock Option Plan. In the fiscal year ended April 30, 1998, we adopted the 1997 Stock Option Plan (“1997 Plan”) a stock option plan for employees, officers and directors of, and consultants and advisors to us. The 1997 Plan terminated as of July 31, 2007 and as a result no additional awards may be made pursuant to the 1997 Plan.

2006 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. Under the 2006 Plan, we may grant awards up to an aggregate amount of shares equal to the sum of: (i) 2,475 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 as were subject to options granted under our 1993 Incentive Stock Option Plan, 1994 Non-statutory Stock Option Plan, 1996 Stock Option Plan, and 1997 Plan (“Prior Plans”), which were not actually issued under the Prior Plans because such stock options expire or otherwise result in shares not being issued. As of December 31, 2015, there were 956 Class A common stock equivalents available for future grant under the 2006 Plan, inclusive of additional Class A common stock equivalents that were previously issued under our terminated plans and have become available for grant because such awards expired or otherwise resulted in shares not being issued. No award may be granted under the 2006 Plan after October 10, 2016 and accordingly we expect to implement a new stock incentive plan which would be recommended to stockholders for approval at the 2016 Annual Meeting of Stockholders.

Stock options granted under the 2006 Plan are granted at a price equal to the prevailing fair market 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 to four year period from the date of grant.

We grant restricted stock awards, restricted stock units and performance stock units under the 2006 Plan at a price equal to the fair market value of our Class A common stock at the date of grant. Restricted stock awards granted to non-employee directors vest incrementally over a three year period beginning on the first anniversary of the date of grant. Restricted stock units vest incrementally over an identified service period beginning on the grant date based on continued employment. Performance stock units vest at a future date following the grant date and are based on the attainment of a performance target.

During fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, stock-based compensation expense for stock options was $671, $386, $464, and $528, respectively.

During fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, the aggregate intrinsic value of stock options exercised was $52, $31, $23 and $0.

As of December 31, 2015, total unrecognized stock-based compensation expense related to outstanding stock options was $1,225, which will be recognized over a weighted average period of 2.3 years.

Our calculation of stock-based compensation expense associated with stock options granted was made using the Black-Scholes valuation model. The weighted average fair value of stock options granted during fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013 were $5.35, $3.62, $4.22 and $3.03 per option, respectively, which were calculated assuming no expected dividend yield using the following weighted average assumptions:

	Fiscal Year Ended		Eight Months Ended		Fiscal Year Ended April 30,
	December 31, 2015		December 31, 2014		2014		2013
Expected life		7.24 years		7.00 years		6.79 years		6.82 years
Risk-free interest rate		2.02%		2.15%		2.22%		1.14%
Expected volatility		81.31%		82.76%		83.96%		84.40%

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.

The Black-Scholes valuation model requires extensive use of accounting judgment and financial estimation, including estimates of the expected term option holders will retain their vested stock options before exercising them, the estimated volatility of our Class A common stock price over the expected term and the number of stock options that will be forfeited prior to the completion of their vesting requirements. 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.

During fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, stock-based compensation expense related to restricted stock, restricted stock units and performance stock units was $2,314, $1,202, $1,861 and $1,609, respectively. Stock-based compensation expense related to restricted stock and restricted stock units during fiscal year 2015 included $270 of incremental compensation expense resulting from the modification of restricted stock awards associated with the retirement of two members of our Board of Directors. There was $19, $0, $0 and $0 of tax benefit in the provision for income taxes associated with stock-based compensation expense during fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013.

During fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, the total fair value of other stock awards vested was $2,340, $1,866, $1,458 and $2,475, respectively.

As of December 31, 2015, total unrecognized stock-based compensation expense related to restricted stock and restricted stock units was $2,674, which will be recognized over a weighted average period of 1.8 years. We recorded a tax benefit of $185, $84, $0 and $96 to additional paid-in-capital related to the exercise of various share based awards in fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, respectively. Tax savings from stock-based compensation resulting from tax deductions in excess of expense are reflected as a financing cash flow in our consolidated financial statements.

We also recorded $94, $52, $79 and $99 of stock-based compensation expense related to our Amended and Restated 1997 Employee Stock Purchase Plan during fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, respectively.

12. FAIR VALUE OF FINANCIAL INSTRUMENTS

We use a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. These tiers include: Level 1, defined as quoted market prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; and Level 3, defined as unobservable inputs that are not corroborated by market data.

We use valuation techniques that maximize the use of market prices and observable inputs and minimize the use of unobservable inputs. In measuring the fair value of our financial assets and liabilities, we rely on market data or assumptions which we believe market participants would use in pricing an asset or a liability.

Assets and Liabilities Accounted for at Fair Value on a Recurring Basis

Our financial instruments include cash and cash equivalents, restricted investments 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, trade receivables, interest rate derivatives, trade payables and long-term debt. The carrying values of cash and cash equivalents, trade receivables and trade payables approximate their respective fair values due to their short-term nature. The fair value of restricted investments held in trust and escrow accounts is included as restricted assets in the Level 1 tier below, along with restricted cash reserved for repayment of costs incurred to fund certain capital projects.

109

The fair value of the interest rate derivative as of December 31, 2015, included in the Level 2 tier below, is calculated based on a valuation obtained from our counter-party based primarily on the three month LIBOR yield curve that is observable at commonly quoted intervals for the full term of the swap. Previously, it was calculated by us based on the three month LIBOR yield curve that is observable at commonly quoted intervals for the full term of the swap, adjusted by the credit risk of our counter-party and us based on observable credit default swap rates. The change in valuation method is due to the immaterial credit risk impact of our counter-party and us based on the short term nature of the interest rate swap, which matures on March 15, 2016. We recognize all derivatives on the balance sheet at fair value. See Note 9, Long-Term Debt and Capital Leases for disclosure over the fair value of debt.

Non-Recurring Fair Value Measurements

Our assets and liabilities that are measured at fair value on a non-recurring basis include the following:

	Fair Value Measurement at December 31, 2015 Using:
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

	$	—	$	—	$	1,378

As of December 31, 2015, our financial assets and liabilities recorded at fair value on a non-recurring basis include our cost method investments in GreenerU and Recycle Rewards. The fair value of our cost method investment in GreenerU was measured by a third-party valuation specialist who completed a valuation analysis using a market approach based on an option pricing methodology that considers comparable publicly traded companies revenue multiples to determine an equity value and fair market value per share for GreenerU, which we used to properly value our cost method investment in GreenerU. The fair value of our cost method investment in RecycleRewards was measured by us when we completed a valuation analysis using 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.

As of April 30, 2014, our financial assets and liabilities recorded at fair value on a non-recurring basis include our assets related to Casella-Altela Regional Environmental Services, LLC (“CARES”). The fair value of our CARES asset group was measured using an in-exchange valuation premise under the market approach derived from quoted market prices of similar assets, adjusted based on qualitative factors specific to the asset group.

13. EMPLOYEE BENEFIT PLANS

Defined Contribution Plan

We 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 ratably over a three year period. Employer contributions for fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013 amounted to $1,033, $497, $784 and $645, respectively.

Employee Stock Purchase Plan

In the fiscal year ended April 30, 1998, we implemented our 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. An aggregate of 1,200 shares of Class A common stock were initially reserved for this purpose. During fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, 80, 79, 70 and 76 shares, respectively, of Class A common stock remained issued under this plan. As of December 31, 2015, 255 shares of Class A common stock were available for distribution under this plan.

14. INCOME TAXES

The provision (benefit) for income taxes from continuing operations consists of the following:

	Fiscal Year Ended December 31,			Eight Months Ended December 31,			Fiscal Year Ended April 30,
	2015			2014			2014		2013

	$	1,351		$	703		$	1,799	$	(2,526	)

Included in the current state tax provision for fiscal year 2013 is an $800 settlement with New York State, comprised of $430 of tax and $370 of interest. New York State had alleged that we were not permitted to file a single combined corporation franchise tax return with our subsidiaries. On January 18, 2011, the State had assessed a liability of $3,852, comprising $2,220 tax and $1,632 penalties and interest, for tax years ending April 30, 2004 through April 30, 2006. We had filed Petitions of Redetermination with the State of New York Division of Tax Appeals and had been scheduled for an administrative hearing on April 18-19, 2013. Tax years ending April 30, 2007 through April 30, 2009 were also being audited for the same tax matter. The settlement, which represented less than 8% of the potential cumulative liability for the years settled, was a monetary settlement without any change to our filing combined returns in New York and it closed tax years ending April 30, 2004 through April 30, 2010. Subsequent to the settlement of that audit, the State of New York began an audit of the tax years ended April 30, 2011 through April 30, 2013 and raised the same issue. We continued to believe that our position related to the filing of our State of New York tax returns was correct, and, based on the prior settlement and subsequent favorable litigation related to similar issues, we concluded at December 31, 2014 that no reserve would be required for our State of New York filings. During fiscal year 2015, we reached a settlement with the State of New York for the tax years ended April 30, 2011 through April 30, 2013 on a basis similar to the prior settlement to minimize out-of-pocket costs. Included in the current state tax provision for fiscal year 2015 is a $180 settlement paid to the State of New York for 2011-2013, which includes $168 tax and $12 interest. No audit has been initiated for tax years after 2013. Due to a change in law, we are permitted to and plan to elect to file a single combined corporation franchise tax return with our subsidiaries in New York beginning with 2015. We have not established any reserve under ASC 740 for the tax years ended April 30, 2014 and December 31, 2014, since we believed our position would more likely than not be successful.

112

The differences in the provision (benefit) for income taxes and the amounts determined by applying the Federal statutory rate to income before provision (benefit) for income taxes are as follows:

	Fiscal Year Ended December 31,			Eight Months Ended December 31,			Fiscal Year Ended April 30,

	$	1,351		$	703		$	1,799		$	(2,526	)

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. Deferred tax assets and liabilities consist of the following:

	December 31,						April 30,
	2015			2014			2014
Deferred tax assets:
Book over tax depreciation of property and equipment	$	37,383		$	31,535		$	28,868

Total deferred tax assets after valuation allowance		23,435			23,938			24,044
Deferred tax liabilities:
Amortization of intangibles		(28,935	)		(28,659	)		(28,210	)
Other		(95	)		(264	)		(286	)
Total deferred tax liabilities		(29,030	)		(28,923	)		(28,496	)
Net deferred tax liability	$	(5,595	)	$	(4,985	)	$	(4,452	)

As of December 31, 2015 we have, for federal income tax purposes, net operating loss carryforwards of approximately $72,873 that expire in the fiscal years ending December 31, 2032 through 2033 and state net operating loss carryforwards of approximately $86,351 that expire in the fiscal years ending December 31, 2016 through 2035. The net operating loss carryforwards include approximately $383 for which a benefit will be recorded in additional paid-in capital when realized. In addition, we have $3,766 minimum tax credit carryforwards available that are not subject to a time limitation and $3,379 general business credit carryforwards which expire in the fiscal years ending December 31, 2023 through 2035. Sections 382 and 383 of the Internal Revenue Code can

113

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. 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 net increase in the valuation allowance was $5,886 for fiscal year 2015 and $2,581 for transition period 2014. For fiscal year 2013, the valuation allowance decreased by $5,084 due to the recognition of additional reversing temporary differences from the deferred tax liability recorded through goodwill related to the BBI acquisition. The $5,084 deferred tax liability related to the BBI acquisition resulted from temporary differences related to the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for income tax purposes.

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, the availability of tax planning strategies, 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. We believe we are able to support the deferred tax assets recognized as of the end of the year based on all of the available evidence. The net deferred tax liability as of December 31, 2015 includes deferred tax liabilities related to amortizable goodwill, which are anticipated to reverse in an indefinite future period and which are not currently available as a source of taxable income.

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, 2015			Eight Months Ended December 31, 2014			Fiscal Year Ended April 30, 2014
Unrecognized tax benefits at beginning of period	$	3,073		$	3,061		$	3,879
Gross increases for tax positions of prior years		168			14			22
Gross decreases for tax positions of prior years		(1	)		(1	)		(229	)
Reductions resulting from lapse of statute of limitations		(409	)		(1	)		(611	)
Gross increases resulting from reversal of benefit from lapse of statute of limitations		716			—			—
Settlements		(168	)		—			—
Unrecognized tax benefits at end of period	$	3,379		$	3,073		$	3,061

The gross increases for tax positions of prior years for fiscal year 2015 includes $168 tax from the settlement with New York State, which is offset by the ($168) settlements for fiscal year 2015. Included in the balances at December 31, 2015, December 31, 2014 and April 30, 2014 are $279, $0 and $0, 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 a decrease of $270 to unrecognized tax benefits 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 year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, we have accrued interest of $92, $143, $116 and $76 and penalties of $8, $8, $8 and $9, respectively. We accrued ($51), $26, $40 and $41 for interest and penalties in income tax expense related to uncertain tax positions during fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, 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 2015 remain open for examination, with limited exceptions.

15. OTHER ITEMS AND CHARGES

Environmental Remediation Charge

In transition period 2014, we recorded an environmental remediation charge of $950 associated with remediation performed at Southbridge in the Eastern region. We had previously recorded an environmental remediation charge of $400 in fiscal year 2014 associated with remediating this site.

Expense from Divestiture, Acquisition and Financing Costs

In fiscal year 2014, we incurred $144 of expenses primarily associated with legal costs for the acquisition of the remaining 50% membership interest of Tompkins. See Note 3, Summary of Significant Accounting Policies for disclosure over the acquisition of Tompkins.

In fiscal year 2013, we incurred $1,410 of expenses including a $303 write-off of costs associated with the attempted refinancing of our Second Lien Notes, $602 of legal costs associated with the divestiture of Maine Energy Recovery Company, LP (“Maine Energy”) divestiture transaction, as discussed in Note 16, Divestiture Transactions and Discontinued Operations, and $505 of costs associated with the BBI acquisition.

Development Project Charge

In fiscal year 2014, we recorded a charge of $1,394 for deferred costs associated with a gas pipeline development project in Maine no longer deemed viable.

Severance and Reorganization Costs

In fiscal year 2014, we recorded a charge of $586 for severance costs associated with various planned reorganization efforts including the divestiture of Maine Energy.

In fiscal year 2013, we recorded a charge of $3,709 for severance costs associated primarily with the realignment of our operations in order to streamline functions and improve our cost structure, the closure of Maine Energy and a reorganization of senior management. Through the realignment of our operations we improved certain aspects of the sales function to better facilitate customer service and retention, pricing growth, and support of strategic growth initiatives; better aligned transportation, route management and maintenance functions at the local level; and reduced corporate overhead and staff to match organizational needs and reduce costs.

16. DIVESTITURE TRANSACTIONS AND DISCONTINUED OPERATIONS

We review planned business dispositions based on available information and events that have occurred to determine whether or not a business or disposal group qualifies for discontinued operations treatment. We analyze our operations that have been divested or classified as held-for-sale to determine if they qualify for discontinued operations accounting. A component of an entity, a group of components of an entity, or a business is required to be reported in discontinued operations once it meets the held for sale criteria, is disposed of by sale, or is disposed of other than by sale. A disposal is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. We evaluate whether the component has met the criteria to be classified as held-for-sale. To be classified as held-for-sale, the criteria established by FASB ASC 360-10 must be met as of the reporting date, including an active program to market the business and the disposition of the business within one year. A business that has not been disposed of may not be classified as discontinued operations until the held-for-sale criteria are met. No depreciation is recorded during the periods in which a disposal group is classified as held-for-sale.

Discontinued Operations

In fiscal year 2013, we initiated a plan to dispose of BioFuels and as a result, the assets associated with BioFuels were classified as held-for-sale and the results of operations were recorded as income from discontinued operations. Assets of the disposal group previously classified as held-for-sale, and subsequently included in discontinued operations, included certain inventory along with plant and equipment. In the first quarter of fiscal year 2014, we executed a purchase and sale agreement with ReEnergy Lewiston LLC

115

(“ReEnergy”), pursuant to which we agreed to sell certain assets of BioFuels, which was located in our Eastern region, to ReEnergy. We agreed to sell the BioFuels assets for undiscounted purchase consideration of $2,000, which was to be paid to us in equal quarterly installments over five years commencing November 1, 2013, subject to the terms of the purchase and sale agreement. The related note receivable was paid in full by ReEnergy in transition period 2014. We recognized a $378 loss on disposal of discontinued operations in fiscal year 2014 associated with the disposition.

The operating results of these operations, including those related to prior years, have been reclassified from continuing to discontinued operations in the accompanying consolidated financial statements. Revenues and loss before income taxes attributable to discontinued operations are as follows:

	Fiscal Year Ended December 31,		Eight Months Ended December 31,		Fiscal Year Ended April 30,
	2015		2014		2014		2013
Revenues	$	—	$	—	$	3,316	$	12,033
Income (loss) before income taxes	$	—	$	—	$	284	$	(4,480	)

We allocate interest expense to discontinued operations. We have also eliminated inter-company activity associated with discontinued operations.

Divestiture Transactions

Sale of Business. In fiscal year 2015, we divested of a business, which included the sale of certain assets associated with various waste collection routes in the Western region, for total consideration of $872, resulting in a gain of $590.

Maine Energy. In fiscal year 2013, we executed a purchase and sale agreement with the City of Biddeford, Maine, pursuant to which we agreed to sell the real property of Maine Energy to the City of Biddeford. We agreed to sell Maine Energy for an undiscounted purchase consideration of $6,650, which was to be paid to us in installments over twenty-one years. The transaction closed in November 2012. In December 2012, we ceased operations of the Maine Energy facility and initiated the decommissioning, demolition and site remediation process in accordance with the provisions of the agreement. We have completed the demolition process and site remediation under the auspices and in accordance with work plans approved by the Maine Department of Environmental Protection and the U.S. Environmental Protection Agency. Based on the total incurred costs to fulfill our obligation under the agreement, we reversed a reserve of $1,149 of excess costs to complete the divestiture in fiscal year 2015. As of December 31, 2015, we had no remaining costs to complete the divestiture accrued as we had fulfilled our obligation under the agreement.

CARES and Related Transaction. CARES is a joint venture that owned and operated a water and leachate treatment facility for the natural gas drilling industry in Pennsylvania. Our joint venture partner in CARES is Altela, Inc. (“Altela”). We held an ownership interest in CARES of 51% and, in accordance with FASB ASC 810-10-15, we consolidated the assets, liabilities and results of operations of CARES into our consolidated financial statements due to our controlling financial interest in the joint venture. In fiscal year 2014, we determined that assets of the CARES water treatment facility were no longer operational or were not operating within product performance parameters. As a result, we initiated a plan to abandon and shut down the operations of CARES. It was determined that the carrying value of the assets of CARES was no longer recoverable and, as a result, the carrying value of the asset group was assessed for impairment and impaired in transition period 2014. As a result, we recorded an impairment charge of $7,455 transition period 2014 to the asset group of CARES in the Western region.

We executed a purchase and sale agreement in fiscal year 2015 pursuant to which we and Altela agreed to sell certain assets of the CARES water treatment facility to an unrelated third-party. We sold these assets of CARES for purchase consideration of $3,500, resulting in a gain of $2,850 in fiscal year 2015, 49% of which was attributable to Altela, the noncontrolling interest holder. As of December 31, 2015, we continued to pursue the dissolution of CARES in accordance with the CARES agreement.

In connection with this transaction, we also sold certain of our equipment and real estate to the same unrelated third-party for total consideration of $1,050, resulting in a gain of $928 in fiscal year 2015.

BioFuels. In transition period 2014, we recorded a $553 gain associated with the disposition of BioFuels in fiscal year 2014. As a part of the divestiture, we agreed to complete certain site improvements at BioFuels which were completed in December 2014. The gain recorded is the result of reversing the excess remaining reserves not needed to complete the site improvements.

18. RELATED PARTY TRANSACTIONS

Services

During fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, we retained the services of CCI, a company wholly owned by 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. Total purchased services charged to operations or capitalized to landfills for fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013 were $1,341, $5,562, $7,818 and $6,574, respectively, of which $28, $2 and $890 were outstanding and included in either accounts payable or other current liabilities as of December 31, 2015, December 31, 2014 and April 30, 2014, respectively.

In addition to the total purchased services, CCI contributed $350 in cash and $390 in non-compensable services for work performed at the Southbridge landfill to assist in the remediation of the site. See Note 15, Other Items and Charges for discussion over the Southbridge landfill environmental remediation.

Leases

In 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 April 2018 with a five year option to extend the terms. The terms of the lease agreements require monthly payments of approximately $27. Total expense charged to operations for fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013 under these agreements was $384, $263, $386 and $286, respectively.

Landfill Post-closure

We 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 year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, we paid $9, $8, $8, and $8, respectively, pursuant to this agreement. As of December 31, 2015, December 31, 2014 and April 30, 2014, we have accrued $75, $84 and $94, respectively, for costs associated with its post-closure obligations.

117

Employee Loan

In fiscal year 2014, we entered into an agreement with an employee to amend a promissory note, whereas the outstanding balance of $149, which had been included in Notes receivable – related party in the accompanying consolidated balance sheet, will be deemed paid in full in exchange for continued employment and the employee forgoing participation in the annual cash incentive plan and restricted stock program for a period of time specified in the amended note. Upon entering into the amended note, interest ceased accruing on the note and we recorded a charge of $149 in general and administration to reserve for the note.

19. SEGMENT REPORTING

We 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, the 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, major account and industrial services, discontinued operations, and earnings from equity method investees, as applicable, are included in our Other segment.

Our transfer and disposal revenues historically have been lower from the months of November through March. 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 newspaper advertising and retail activity during the holiday season.

ITEM 9A. CONTROLS AND PROCEDURES

Management’s Report on Internal Control Over Financial Reporting

Our 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, 2015. 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, 2015, 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, 2015 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.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2015. 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, 2015, 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.

The independent registered public accounting firm’s related audit report is included in Item 8 of this Annual Report on Form 10-K and is incorporated herein by reference.

No change in our internal control over financial reporting occurred during the fiscal quarter ended December 31, 2015 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Exhibit 10.13

CASELLA WASTE SYSTEMS, INC.

2006 STOCK INCENTIVE PLAN, AS AMENDED

1. Purpose

The purpose of this 2006 Stock Incentive Plan (the “Plan”) of Casella Waste Systems, Inc., a Delaware corporation (the “Company”), is to advance the interests of the Company’s stockholders by enhancing the Company’s ability to attract, retain and motivate persons who are expected to make important contributions to the Company and by providing such persons with equity ownership opportunities and performance-based incentives that are intended to align their interests with those of the Company’s stockholders. Except where the context otherwise requires, the term “Company” shall include any of the Company’s present or future parent or subsidiary corporations as defined in Sections 424(e) or (f) of the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder (the “Code”) and any other business venture (including, without limitation, joint venture or limited liability company) in which the Company has a controlling interest, as determined by the Board of Directors of the Company (the “Board”).

2. Eligibility

All of the Company’s employees, officers, directors, consultants and advisors are eligible to receive options, stock appreciation rights, restricted stock, restricted stock units and other stock-based awards (each, an “Award”) under the Plan. Each person who receives an Award under the Plan is deemed a “Participant”.

3. Administration and Delegation

(a) Administration by Board of Directors. The Plan will be administered by the Board. The Board shall have authority to grant Awards and to adopt, amend and repeal such administrative rules, guidelines and practices relating to the Plan as it shall deem advisable. The Board may construe and interpret the terms of the Plan and any Award agreements entered into under the Plan. The Board may correct any defect, supply any omission or reconcile any inconsistency in the Plan or any Award in the manner and to the extent it shall deem expedient to carry the Plan into effect and it shall be the sole and final judge of such expediency. All decisions by the Board shall be made in the Board’s sole discretion and shall be final and binding on all persons having or claiming any interest in the Plan or in any Award. No director or person acting pursuant to the authority delegated by the Board shall be liable for any action or determination relating to or under the Plan made in good faith.

(b) Appointment of Committees. To the extent permitted by applicable law, the Board may delegate any or all of its powers under the Plan to one or more committees or subcommittees of the Board (a “Committee”). All references in the Plan to the “Board” shall mean the Board or a Committee of the Board to the extent that the Board’s powers or authority under the Plan have been delegated to such Committee. During such time as the Class A Common Stock, $0.01 par value per share, of the Company (the “Common Stock”) is registered under the Securities Exchange Act of 1934 (the “Exchange Act”), the Board shall appoint one such Committee of not less than two members, each member of which shall be an “outside director” within the meaning of Section 162(m) of the Code and a “non-employee director” as defined in Rule 16b-3 promulgated under the Exchange Act. Grants of Awards intended to comply with Section 162(m) shall be made only by such Committee.

(c) Delegation to Officers. To the extent permitted by applicable law, the Board may delegate to one or more officers of the Company the power to grant Awards to employees or officers of the Company or any of its present or future subsidiary corporations and to exercise such other powers under the Plan as the Board may determine, provided that the Board shall fix the terms of the Awards to be granted by such officers (including the exercise price of such Awards, which may include a formula by which the exercise price will be determined) and the maximum number of shares subject to Awards that the officers may grant; provided further, however, that no officer shall be authorized to grant Awards to any “executive officer” of the Company (as defined by Rule 3b-7 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) or to any “officer” of the Company (as defined by Rule 16a-1 under the Exchange Act).

4. Stock Available for Awards

(a) Number of Shares. Subject to adjustment under Section 9, Awards may be made under the Plan for up to such number of shares of Common Stock as is equal to the sum of: (i) 2,475,000 shares of Common Stock, plus (ii) such

additional number of shares of Common Stock as is equal to the aggregate number of shares subject to Awards previously granted under the Company’s 1993 Incentive Stock Option Plan, 1994 Nonstatutory Stock Option Plan, 1996 Stock Option Plan, and 1997 Stock Inventive Plan (the “Terminated Plans”), which are not actually issued because such awards expire or otherwise result in shares not being issued. To the extend that shares are issued pursuant to options previously granted under the Terminated Plans, such shares will not be available for issuance under the Plan. For purposes of counting the number of shares available for the grant of Awards under the Plan, (i) shares of Common Stock covered by independent SARs shall be counted against the number of shares available for the grant of Awards under the Plan; provided, however, that independent SARs that may be settled in cash only shall not be so counted; (ii) if any Award (A) expires or is terminated, surrendered or canceled without having been fully exercised or is forfeited in whole or in part (including as the result of shares of Common Stock subject to such Award being repurchased by the Company at the original issuance price pursuant to a contractual repurchase right) or (B) results in any Common Stock not being issued (including as a result of an independent SAR that was settleable either in cash or in stock actually being settled in cash), the unused Common Stock covered by such Award shall again be available for the grant of Awards under the Plan; provided, however, in the case of Incentive Stock Options (as hereinafter defined), the foregoing shall be subject to any limitations under the Code; and (iii) shares of Common Stock tendered to the Company by a Participant to (A) purchase shares of Common Stock upon the exercise of an Award or (B) satisfy tax withholding obligations (including shares retained from the Award creating the tax obligation) shall not be added back to the number of shares available for the future grant of Awards under the Plan. Shares issued under the Plan may consist in whole or in part of authorized but unissued shares or treasury shares. No more than 3,016,850 shares of Common Stock could become available for issuance under the Plan from awards outstanding under the Terminated Plans.

(b) Sub-limits. Subject to adjustment under Section 9, the maximum number of shares of Common Stock with respect to which Awards may be granted to any Participant under the Plan shall be 200,000 per fiscal year. For purposes of the foregoing limit, the combination of an Option in tandem with a SAR (as each is hereafter defined) shall be treated as a single Award. The per-Participant limit described in this Section 4(b) shall be construed and applied consistently with Section 162(m) of the Code or any successor provision thereto, and the regulations thereunder (“Section 162(m)”).

(c) Substitute Awards. In connection with a merger or consolidation of an entity with the Company or the acquisition by the Company of property or stock of an entity, the Board may grant Awards in substitution for any options or other stock or stock-based awards granted by such entity or an affiliate thereof. Substitute Awards may be granted on such terms as the Board deems appropriate in the circumstances, notwithstanding any limitations on Awards contained in the Plan. Substitute Awards shall not count against the overall share limit set forth in Section 4(a), except as may be required by reason of Section 422 and related provisions of the Code.

5. Stock Options

(a) General. The Board may grant options to purchase Common Stock (each, an “Option”) and determine the number of shares of Common Stock to be covered by each Option, the exercise price of each Option and the conditions and limitations applicable to the exercise of each Option, including conditions relating to applicable federal or state securities laws, as it considers necessary or advisable. An Option that is not intended to be an Incentive Stock Option (as hereinafter defined) shall be designated a “Nonstatutory Stock Option.”

(b) Incentive Stock Options. An Option that the Board intends to be an “incentive stock option” as defined in Section 422 of the Code (an “Incentive Stock Option”) shall only be granted to employees of the Company, any of the Company’s present or future parent or subsidiary corporations as defined in Sections 424(e) or (f) of the Code, and any other entities the employees of which are eligible to receive Incentive Stock Options under the Code, and shall be subject to and shall be construed consistently with the requirements of Section 422 of the Code. The Company shall have no liability to a Participant, or any other party, if an Option (or any part thereof) that is intended to be an Incentive Stock Option is not an Incentive Stock Option or for any action taken by the Board, including without limitation the conversion of an Incentive Stock Option to a Nonstatutory Stock Option.

(c) Exercise Price. The Board shall establish the exercise price of each Option and specify such exercise price in the applicable option agreement; provided, however, that the exercise price shall be not less than 100% of the Fair Market Value (as defined below) on the date the Option is granted.

(d) Duration of Options. Each Option shall be exercisable at such times and subject to such terms and conditions as the Board may specify in the applicable option agreement, provided, however, that no Option will be granted for a term in excess of 10 years.

(e) No Reload Rights. No Option granted under the Plan shall contain any provision entitling the optionee to the automatic grant of additional Options in connection with any exercise of the original Option.

(f) Exercise of Option. Options may be exercised by delivery to the Company of a written notice of exercise signed by the proper person or by any other form of notice (including electronic notice) approved by the Board, together with payment in full as specified in Section 5(g) for the number of shares for which the Option is exercised. Shares of Common Stock subject to the Option will be delivered by the Company following exercise either as soon as practicable or, subject to such conditions as the Board shall specify, on a deferred basis (with the Company’s obligation to be evidenced by an instrument providing for future delivery of the deferred shares at the time or times specified by the Board).

(g) Payment Upon Exercise. Common Stock purchased upon the exercise of an Option granted under the Plan shall be paid for as follows:

(1) in cash or by check, payable to the order of the Company;

(2) except as may otherwise be provided in the applicable option agreement, by (i) delivery of an irrevocable and unconditional undertaking by a creditworthy broker to deliver promptly to the Company sufficient funds to pay the exercise price and any required tax withholding or (ii) delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a creditworthy broker to deliver promptly to the Company cash or a check sufficient to pay the exercise price and any required tax withholding;

(3) to the extent provided for in the applicable option agreement or approved by the Board, in its sole discretion, by delivery (either by actual delivery or attestation) of shares of Common Stock owned by the Participant valued at their fair market value as determined by (or in a manner approved by) the Board (“Fair Market Value”), provided (i) such method of payment is then permitted under applicable law, (ii) such Common Stock, if acquired directly from the Company, was owned by the Participant for such minimum period of time, if any, as may be established by the Board in its discretion and (iii) such Common Stock is not subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements;

(4) to the extent permitted by applicable law and provided for in the applicable option agreement or approved by the Board, in its sole discretion, by (i) delivery of a promissory note of the Participant to the Company on terms determined by the Board, or (ii) payment of such other lawful consideration as the Board may determine; or

(5) by any combination of the above permitted forms of payment.

(h) Limitation on Repricing. Unless such action is approved by the Company’s stockholders: (i) no outstanding Option granted under the Plan may be amended to provide an exercise price per share that is lower than the then-current exercise price per share of such outstanding Option (other than adjustments pursuant to Section 9) and (ii) the Board may not cancel any outstanding option (whether or not granted under the Plan) and grant in substitution therefor new Awards under the Plan covering the same or a different number of shares of Common Stock and having an exercise price per share lower than the then-current exercise price per share of the cancelled option.

6. Stock Appreciation Rights.

(a) General. The Board may grant Awards consisting of a Stock Appreciation Right (“SAR”) entitling the holder, upon exercise, to receive an amount in Common Stock or cash or a combination thereof (such form to be determined by the Board) determined by reference to appreciation, from and after the date of grant, in the fair market value of a share of Common Stock. The date as of which such appreciation or other measure is determined shall be the exercise date.

(b) Grants. Stock Appreciation Rights may be granted in tandem with, or independently of, Options granted under the Plan.

(1) Tandem Awards. When Stock Appreciation Rights are expressly granted in tandem with Options, (i) the Stock Appreciation Right will be exercisable only at such time or times, and to the extent, that the related Option is exercisable (except to the extent designated by the Board in connection with a Reorganization Event) and will be exercisable in accordance with the procedure required for exercise of the related Option; (ii) the Stock Appreciation Right will terminate and no longer be exercisable upon the termination or exercise of the related

Option, except to the extent designated by the Board in connection with a Reorganization Event and except that a Stock Appreciation Right granted with respect to less than the full number of shares covered by an Option will not be reduced until the number of shares as to which the related Option has been exercised or has terminated exceeds the number of shares not covered by the Stock Appreciation Right; (iii) the Option will terminate and no longer be exercisable upon the exercise of the related Stock Appreciation Right; and (iv) the Stock Appreciation Right will be transferable only with the related Option.

(2) Independent SARs. A Stock Appreciation Right not expressly granted in tandem with an Option will become exercisable at such time or times, and on such conditions, as the Board may specify in the SAR Award.

(c) Grant Price. The grant price or exercise price of an SAR shall not be less than 100% of the Fair Market Value per share of Common Stock on the date of grant of the SAR.

(d) Term. The term of an SAR shall not be more than 10 years from the date of grant.

(e) Exercise. Stock Appreciation Rights may be exercised by delivery to the Company of a written notice of exercise signed by the proper person or by any other form of notice (including electronic notice) approved by the Board, together with any other documents required by the Board.

7. Restricted Stock; Restricted Stock Units.

(a) General. The Board may grant Awards entitling recipients to acquire shares of Common Stock (“Restricted Stock”), subject to the right of the Company to repurchase all or part of such shares at their issue price or other stated or formula price (or to require forfeiture of such shares if issued at no cost) from the recipient in the event that conditions specified by the Board in the applicable Award are not satisfied prior to the end of the applicable restriction period or periods established by the Board for such Award. Instead of granting Awards for Restricted Stock, the Board may grant Awards entitling the recipient to receive shares of Common Stock to be delivered at the time such shares of Common Stock vest (“Restricted Stock Units”) (Restricted Stock and Restricted Stock Units are each referred to herein as a “Restricted Stock Award”).

(b) Limitations on Vesting.

(1) Restricted Stock Awards that vest based on the passage of time alone shall be zero percent vested prior to the first anniversary of the date of grant, no more than 331/3% vested prior to the second anniversary of the date of grant, and no more than 662/3% vested prior to the third anniversary of the date of grant. Restricted Stock Awards that vest upon the passage of time and provide for accelerated vesting based on performance shall not vest prior to the first anniversary of the date of grant. This subsection (7)(b)(1) shall not apply to Awards granted pursuant to Section 10(i).

(2) Notwithstanding any other provision of this Plan, the Board may, in its discretion, either at the time a Restricted Stock Award is made or at any time thereafter, waive its right to repurchase shares of Common Stock (or waive the forfeiture thereof) or remove or modify any part or all of the restrictions applicable to the Restricted Stock Award, provided that the Board may only exercise such rights in extraordinary circumstances which shall include, without limitation, death or disability of the Participant; estate planning needs of the Participant; a merger, consolidation, sale, reorganization, recapitalization, or change in control of the Company; or any other nonrecurring significant event affecting the Company, a Participant or the Plan.

(c) Terms and Conditions for all Restricted Stock Awards. The Board shall determine the terms and conditions of a Restricted Stock Award, including the conditions for vesting and repurchase (or forfeiture) and the issue price, if any.

(d) Additional Provisions Relating to Restricted Stock.

(1) Dividends. Participants holding shares of Restricted Stock will be entitled to all ordinary cash dividends paid with respect to such shares, unless otherwise provided by the Board. If any dividends or distributions are paid in shares, or consist of a dividend or distribution to holders of Common Stock other than an ordinary cash dividend, the shares, cash or other property will be subject to the same restrictions on transferability and forfeitability as the shares of Restricted Stock with respect to which they were paid. Each dividend payment will be made no later than the end of the fiscal year in which the dividends are paid to shareholders of that class of stock or,

if later, the 15th day of the third month following the date the dividends are paid to shareholders of that class of stock.

(2) Stock Certificates. The Company may require that any stock certificates issued in respect of shares of Restricted Stock shall be deposited in escrow by the Participant, together with a stock power endorsed in blank, with the Company (or its designee). At the expiration of the applicable restriction periods, the Company (or such designee) shall deliver the certificates no longer subject to such restrictions to the Participant or if the Participant has died, to the beneficiary designated, in a manner determined by the Board, by a Participant to receive amounts due or exercise rights of the Participant in the event of the Participant’s death (the “Designated Beneficiary”). In the absence of an effective designation by a Participant, “Designated Beneficiary” shall mean the Participant’s estate.

(e) Additional Provisions Relating to Restricted Stock Units.

(1) Settlement. Upon the vesting of and/or lapsing of any other restrictions (i.e., settlement) with respect to each Restricted Stock Unit, the Participant shall be entitled to receive from the Company one share of Common Stock or an amount of cash equal to the Fair Market Value of one share of Common Stock, as provided in the applicable Award agreement. The Board may, in its discretion, provide that settlement of Restricted Stock Units shall be deferred, on a mandatory basis or at the election of the Participant.

(2) Voting Rights. A Participant shall have no voting rights with respect to any Restricted Stock Units.

(3) Dividend Equivalents. To the extent provided by the Board, in its sole discretion, a grant of Restricted Stock Units may provide Participants with the right to receive an amount equal to any dividends or other distributions declared and paid on an equal number of outstanding shares of Common Stock (“Dividend Equivalents”). Dividend Equivalents may be paid currently or credited to an account for the Participants, may be settled in cash and/or shares of Common Stock and may be subject to the same restrictions on transfer and forfeitability as the Restricted Stock Units with respect to which paid, as determined by the Board in its sole discretion, subject in each case to such terms and conditions as the Board shall establish, in each case to be set forth in the applicable Award agreement.

8. Other Stock Unit Awards.

Other Awards of shares of Common Stock, and other Awards that are valued in whole or in part by reference to, or are otherwise based on, shares of Common Stock or other property, may be granted hereunder to Participants (“Other Stock Unit Awards”), including without limitation Awards entitling recipients to receive shares of Common Stock to be delivered in the future and Awards providing cash bonuses based solely on achievement of the performance goals set forth in Section 10(i). Such Other Stock Unit Awards shall also be available as a form of payment in the settlement of other Awards granted under the Plan or as payment in lieu of compensation to which a Participant is otherwise entitled. Other Stock Unit Awards may be paid in shares of Common Stock or cash, as the Board shall determine. Subject to the provisions of the Plan, the Board shall determine the terms and conditions of each Other Stock Unit Award, including any purchase price applicable thereto.

9. Adjustments for Changes in Common Stock and Certain Other Events.

(a) Changes in Capitalization. In the event of any stock split, reverse stock split, stock dividend, recapitalization, combination of shares, reclassification of shares, spin-off or other similar change in capitalization or event, or any dividend or distribution to holders of Common Stock other than an ordinary cash dividend, (i) the number and class of securities available under this Plan, (ii) the sub-limits set forth in Section 4(b), (iii) the share- and per-share provisions and the exercise price of each Stock Appreciation Right, (iv) the number of shares subject to and the repurchase price per share subject to each outstanding Restricted Stock Award and (v) the share- and per-share-related provisions and the purchase price, if any, of each outstanding Other Stock Unit Award, shall be appropriately adjusted by the Company (or substituted Awards may be made, if applicable) to the extent determined by the Board. Without limiting the generality of the foregoing, in the event the Company effects a split of the Common Stock by means of a stock dividend and the exercise price of and the number of shares subject to such Option are adjusted as of the date of the distribution of the dividend (rather than as of the record date for such dividend), then an optionee who exercises an Option between the record date and the distribution date for such stock dividend shall be entitled to receive, on the distribution date, the stock dividend with respect to the shares of Common Stock acquired upon such Option exercise, notwithstanding the fact that such shares were not outstanding as of the close of business on the record date for such stock dividend.

(b) Reorganization Events.

(1) Definition. A “Reorganization Event” shall mean: (a) any merger or consolidation of the Company with or into another entity as a result of which all of the Common Stock of the Company is converted into or exchanged for the right to receive cash, securities or other property or is cancelled, (b) any exchange of all of the Common Stock of the Company for cash, securities or other property pursuant to a share exchange transaction or (c) any liquidation or dissolution of the Company.

(2) Consequences of a Reorganization Event on Awards Other than Restricted Stock Awards. In connection with a Reorganization Event, the Board shall take any one or more of the following actions as to all or any outstanding Awards other than Restricted Stock Awards on such terms as the Board determines: (i) provide that Awards shall be assumed, or substantially equivalent Awards shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), (ii) upon written notice to a Participant, provide that the Participant’s unexercised Options or other unexercised Awards will terminate immediately prior to the consummation of such Reorganization Event unless exercised by the Participant within a specified period following the date of such notice, (iii) provide that outstanding Awards shall become exercisable, realizable, or deliverable, or restrictions applicable to an Award shall lapse, in whole or in part prior to or upon such Reorganization Event, (iv) in the event of a Reorganization Event under the terms of which holders of Common Stock will receive upon consummation thereof a cash payment for each share surrendered in the Reorganization Event (the “Acquisition Price”), make or provide for a cash payment to a Participant equal to the excess, if any, of (A) the Acquisition Price times the number of shares of Common Stock subject to the Participant’s Options or other Awards (to the extent the exercise price does not exceed the Acquisition Price) over (B) the aggregate exercise price of all such outstanding Options or other Awards, in exchange for the termination of such Options or other Awards and any applicable tax withholdings, (v) provide that, in connection with a liquidation or dissolution of the Company, Awards shall convert into the right to receive liquidation proceeds (if applicable, net of the exercise price thereof) and (vi) any combination of the foregoing.

For purposes of clause (i) above, an Option shall be considered assumed if, following consummation of the Reorganization Event, the Option confers the right to purchase, for each share of Common Stock subject to the Option immediately prior to the consummation of the Reorganization Event, the consideration (whether cash, securities or other property) received as a result of the Reorganization Event by holders of Common Stock for each share of Common Stock held immediately prior to the consummation of the Reorganization Event (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Common Stock); provided, however, that if the consideration received as a result of the Reorganization Event is not solely common stock of the acquiring or succeeding corporation (or an affiliate thereof), the Company may, with the consent of the acquiring or succeeding corporation, provide for the consideration to be received upon the exercise of Options to consist solely of common stock of the acquiring or succeeding corporation (or an affiliate thereof) equivalent in value (as determined by the Board) to the per share consideration received by holders of outstanding shares of Common Stock as a result of the Reorganization Event.

(3) Consequences of a Reorganization Event on Restricted Stock Awards. Upon the occurrence of a Reorganization Event other than a liquidation or dissolution of the Company, the repurchase and other rights of the Company under each outstanding Restricted Stock Award shall inure to the benefit of the Company’s successor and shall, unless the Board determines otherwise, apply to the cash, securities or other property which the Common Stock was converted into or exchanged for pursuant to such Reorganization Event in the same manner and to the same extent as they applied to the Common Stock subject to such Restricted Stock Award. Upon the occurrence of a Reorganization Event involving the liquidation or dissolution of the Company, except to the extent specifically provided to the contrary in the instrument evidencing any Restricted Stock Award or any other agreement between a Participant and the Company, all restrictions and conditions on all Restricted Stock Awards then outstanding shall automatically be deemed terminated or satisfied.

10. General Provisions Applicable to Awards

(a) Transferability of Awards. Awards shall not be sold, assigned, transferred, pledged or otherwise encumbered by the person to whom they are granted, either voluntarily or by operation of law, except by will or the laws of descent and distribution or, other than in the case of an Incentive Stock Option, pursuant to a qualified domestic relations order, and, during the life of the Participant, shall be exercisable only by the Participant; provided, however, that the Board may permit or provide in an Award for the gratuitous transfer of the Award by the Participant to or for the benefit of any immediate family member, family trust or other entity established for the benefit of the Participant and/or an immediate family member

thereof if, with respect to such proposed transferee, the Company would be eligible to use a Form S-8 for the registration of the sale of the Common Stock subject to such Award under the Securities Act of 1933, as amended; provided, further, that the Company shall not be required to recognize any such transfer until such time as the Participant and such permitted transferee shall, as a condition to such transfer, deliver to the Company a written instrument in form and substance satisfactory to the Company confirming that such transferee shall be bound by all of the terms and conditions of the Award. References to a Participant, to the extent relevant in the context, shall include references to authorized transferees.

(b) Documentation. Each Award shall be evidenced in such form (written, electronic or otherwise) as the Board shall determine. Each Award may contain terms and conditions in addition to those set forth in the Plan.

(c) Board Discretion. Except as otherwise provided by the Plan, each Award may be made alone or in addition or in relation to any other Award. The terms of each Award need not be identical, and the Board need not treat Participants uniformly.

(d) Termination of Status. The Board shall determine the effect on an Award of the disability, death, termination of employment, authorized leave of absence or other change in the employment or other status of a Participant and the extent to which, and the period during which, the Participant, or the Participant’s legal representative, conservator, guardian or Designated Beneficiary, may exercise rights under the Award.

(e) Withholding. The Participant must satisfy all applicable federal, state, and local or other income and employment tax withholding obligations before the Company will deliver stock certificates or otherwise recognize ownership of Common Stock under an Award. The Company may decide to satisfy the withholding obligations through additional withholding on salary or wages. If the Company elects not to or cannot withhold from other compensation, the Participant must pay the Company the full amount, if any, required for withholding or have a broker tender to the Company cash equal to the withholding obligations. Payment of withholding obligations is due before the Company will issue any shares on exercise or release from forfeiture of an Award or, if the Company so requires, at the same time as is payment of the exercise price unless the Company determines otherwise. If provided for in an Award or approved by the Board in its sole discretion, a Participant may satisfy such tax obligations in whole or in part by delivery of shares of Common Stock, including shares retained from the Award creating the tax obligation, valued at their Fair Market Value; provided, however, except as otherwise provided by the Board, that the total tax withholding where stock is being used to satisfy such tax obligations cannot exceed the Company’s minimum statutory withholding obligations (based on minimum statutory withholding rates for federal and state tax purposes, including payroll taxes, that are applicable to such supplemental taxable income). Shares surrendered to satisfy tax withholding requirements cannot be subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements.

(f) Amendment of Award. Except as otherwise provided in Section 5(h), the Board may amend, modify or terminate any outstanding Award, including but not limited to, substituting therefor another Award of the same or a different type, changing the date of exercise or realization, and converting an Incentive Stock Option to a Nonstatutory Stock Option, provided either (i) that the Participant’s consent to such action shall be required unless the Board determines that the action, taking into account any related action, would not materially and adversely affect the Participant or (ii) that the change is permitted under Section 9 hereof.

(g) Conditions on Delivery of Stock. The Company will not be obligated to deliver any shares of Common Stock pursuant to the Plan or to remove restrictions from shares previously delivered under the Plan until (i) all conditions of the Award have been met or removed to the satisfaction of the Company, (ii) in the opinion of the Company’s counsel, all other legal matters in connection with the issuance and delivery of such shares have been satisfied, including any applicable securities laws and any applicable stock exchange or stock market rules and regulations, and (iii) the Participant has executed and delivered to the Company such representations or agreements as the Company may consider appropriate to satisfy the requirements of any applicable laws, rules or regulations.

(h) Acceleration. The Board may at any time provide that any Award shall become immediately exercisable in full or in part, free of some or all restrictions or conditions, or otherwise realizable in full or in part, as the case may be.

(i) Performance Awards.

(1) Grants. Restricted Stock Awards and Other Stock Unit Awards under the Plan may be made subject to the achievement of performance goals pursuant to this Section 10(i) (“Performance Awards”). With respect to Other Stock Unit Awards providing a cash bonus, the maximum amount of such cash bonus paid to any Participant in any fiscal year shall not exceed $2,000,000.

(2) Committee. Grants of Performance Awards to any Covered Employee intended to qualify as “performance-based compensation” under Section 162(m) (“Performance-Based Compensation”) shall be made only by a Committee (or subcommittee of a Committee) comprised solely of two or more directors eligible to serve on a committee making Awards qualifying as “performance-based compensation” under Section 162(m). In the case of such Awards granted to Covered Employees, references to the Board or to a Committee shall be deemed to be references to such Committee or subcommittee. “Covered Employee” shall mean any person who is a “covered employee” under Section 162(m)(3) of the Code.

(3) Performance Measures. For any Award that is intended to qualify as Performance-Based Compensation, the Committee shall specify that the degree of granting, vesting and/or payout shall be subject to the achievement of one or more objective performance measures established by the Committee, which shall be based on the relative or absolute attainment of specified levels of one or any combination of the following: net income, revenue or earnings each before or after, or otherwise adjusted for, discontinued operations, cost of operations, general and administrative costs, working capital, property plant and equipment, goodwill and intangible assets, interest, taxes, depreciation and/or amortization; operating profit before or after discontinued operations and/or taxes; sales or sales growth; earnings growth; cash flow or cash position; gross margins; stock price; market share; return on sales, assets, equity or investment, with or without adjustment for working capital; improvement of financial ratings; achievement of balance sheet or income statement objectives; or total shareholder return. Such goals may reflect absolute entity or business unit performance or a relative comparison to the performance of a peer group of entities or other external measure of the selected performance criteria and may be absolute in their terms or measured against or in relationship to other companies comparably, similarly or otherwise situated. The Committee may specify that such performance measures shall be adjusted to exclude any one or more of (i) extraordinary items, (ii) gains or losses on the dispositions of discontinued operations, (iii) the cumulative effects of changes in accounting principles, (iv) the writedown of any asset, and (v) charges for restructuring and rationalization programs. Such performance measures: (i) may vary by Participant and may be different for different Awards; (ii) may be particular to a Participant or the department, branch, line of business, subsidiary or other unit in which the Participant works and may cover such period as may be specified by the Committee; and (iii) shall be set by the Committee within the time period prescribed by, and shall otherwise comply with the requirements of, Section 162(m). Awards that are not intended to qualify as Performance-Based Compensation may be based on these or such other performance measures as the Board may determine.

(4) Adjustments. Notwithstanding any provision of the Plan, with respect to any Performance Award that is intended to qualify as Performance-Based Compensation, the Committee may adjust downwards, but not upwards, the cash or number of Shares payable pursuant to such Award, and the Committee may not waive the achievement of the applicable performance measures except in the case of the death or disability of the Participant.

(5) Other. The Committee shall have the power to impose such other restrictions on Performance Awards as it may deem necessary or appropriate to ensure that such Awards satisfy all requirements for Performance-Based Compensation.

11. Miscellaneous

(a) No Right To Employment or Other Status. No person shall have any claim or right to be granted an Award, and the grant of an Award shall not be construed as giving a Participant the right to continued employment or any other relationship with the Company. The Company expressly reserves the right at any time to dismiss or otherwise terminate its relationship with a Participant free from any liability or claim under the Plan, except as expressly provided in the applicable Award.

(b) No Rights As Stockholder. Subject to the provisions of the applicable Award, no Participant or Designated Beneficiary shall have any rights as a stockholder with respect to any shares of Common Stock to be distributed with respect to an Award until becoming the record holder of such shares.

(c) Effective Date and Term of Plan. The Plan shall become effective on the date the Plan is approved by the Company’s stockholders (the “Effective Date”). No Awards shall be granted under the Plan after the completion of 10 years from the Effective Date, but Awards previously granted may extend beyond that date.

(d) Amendment of Plan. The Board may amend, suspend or terminate the Plan or any portion thereof at any time provided that (i) to the extent required by Section 162(m), no Award granted to a Participant that is intended to comply with Section 162(m) after the date of such amendment shall become exercisable, realizable or vested, as applicable to such Award,

unless and until such amendment shall have been approved by the Company’s stockholders if required by Section 162(m) (including the vote required under Section 162(m)); (ii) no amendment that would require stockholder approval under the rules of the NASDAQ Stock Market (“NASDAQ”) may be made effective unless and until such amendment shall have been approved by the Company’s stockholders; and (iii) if the NASDAQ amends its corporate governance rules so that such rules no longer require stockholder approval of material amendments to equity compensation plans, then, from and after the effective date of such amendment to the NASDAQ rules, no amendment to the Plan (A) materially increasing the number of shares authorized under the Plan (other than pursuant to Section 9), (B) expanding the types of Awards that may be granted under the Plan, or (C) materially expanding the class of participants eligible to participate in the Plan shall be effective unless stockholder approval is obtained. In addition, if at any time the approval of the Company’s stockholders is required as to any other modification or amendment under Section 422 of the Code or any successor provision with respect to Incentive Stock Options, the Board may not effect such modification or amendment without such approval. No Award shall be made that is conditioned upon stockholder approval of any amendment to the Plan.

(e) Provisions for Foreign Participants. The Board may modify Awards or Options granted to Participants who are foreign nationals or employed outside the United States or establish subplans or procedures under the Plan to recognize differences in laws, rules, regulations or customs of such foreign jurisdictions with respect to tax, securities, currency, employee benefit or other matters.

(f) Compliance with Section 409A of the Code. Except as provided in individual Award agreements initially or by amendment, if and to the extent any portion of any payment, compensation or other benefit provided to a Participant in connection with his or her employment termination is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code and the Participant is a specified employee as defined in Section 409A(a)(2)(B)(i) of the Code, as determined by the Company in accordance with its procedures, by which determination the Participant (through accepting the Award) agrees that he or she is bound, such portion of the payment, compensation or other benefit shall not be paid before the day that is six months plus one day after the date of “separation from service” (as determined under Code Section 409A) (the “New Payment Date”), except as Code Section 409A may then permit. The aggregate of any payments that otherwise would have been paid to the Participant during the period between the date of separation from service and the New Payment Date shall be paid to the Participant in a lump sum on such New Payment Date, and any remaining payments will be paid on their original schedule.

The Company makes no representations or warranty and shall have no liability to the Participant or any other person if any provisions of or payments, compensation or other benefits under the Plan are determined to constitute nonqualified deferred compensation subject to Code Section 409A but do not to satisfy the conditions of that section.

(g) Governing Law. The provisions of the Plan and all Awards made hereunder shall be governed by and interpreted in accordance with the laws of the State of Delaware, excluding choice-of-law principles of the law of such state that would require the application of the laws of a jurisdiction other than such state.

Basis of Presentation

1. BASIS OF PRESENTATION

Casella Waste Systems, Inc. (“Parent”), and its consolidated subsidiaries (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, the 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, major account and industrial services, discontinued operations and earnings from equity method investees, as applicable, are included in our Other segment.

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.

For comparative purposes, certain prior period amounts in the consolidated statements of operations have been reclassified to confirm to the current fiscal year presentation. The reclassifications had no effect on the previously reported results of operations or retained earnings.

2. ACCOUNTING CHANGES

Adoption of New Accounting Pronouncements

Income Taxes

In November 2015, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update for the accounting for deferred income taxes. The update provides that deferred tax liabilities and assets be classified as noncurrent amounts in a classified statement of financial position. This guidance is effective prospectively or retrospectively for annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2016, with early adoption permitted. We adopted this guidance effective December 31, 2015 in order to simplify the presentation of deferred income taxes. This guidance impacts the balance sheet presentation of our deferred tax liabilities and assets. Prior periods were not retrospectively adjusted.

Discontinued Operations

In April 2014, the FASB issued an accounting standards update for the requirements of reporting discontinued operations. The update provides that an entity, a group of components of an entity, or a business is required to be reported in discontinued operations once it meets the held for sale criteria, is disposed of by sale, or is disposed of other than by sale only if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. The update also requires that additional disclosures about discontinued operations be made. This guidance is effective prospectively for annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2014. We adopted this guidance effective January 1, 2015 with no impact on our consolidated financial position or results of operations.

New Accounting Pronouncements Pending Adoption

Business Combinations

In September 2015, the FASB issued an accounting standards update for the accounting of measurement-period adjustments in business combinations. The update provides that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined as if the accounting had been completed at the acquisition date. This includes the acquirer presenting separately on the face of the income statement or disclosing in the notes thereto the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. This guidance is effective for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted. We expect that this guidance will have no impact on our consolidated financial position or results of operations upon adoption.

Debt Issuance Costs

In April 2015, the FASB issued an accounting standards update for the presentation of debt issuance costs. The update provides that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability. This guidance is effective on a retrospective basis for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted. This guidance will impact the balance sheet presentation of our debt issuance costs and related debt liabilities upon adoption.

Consolidation

In February 2015, the FASB issued an accounting standards update for the requirements of consolidation. The update provides changes to the analysis that an entity must perform to determine whether it should consolidate certain types of legal entities because in certain situations deconsolidated financial statements are necessary to better analyze the reporting entity’s economic and operational results. This guidance is effective for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We are currently assessing the potential impact this guidance may have on our consolidated financial statements as a result of adopting this standard.

Extraordinary and Unusual Items

In January 2015, the FASB issued an accounting standards update that eliminates the GAAP concept of extraordinary items. The update provides for the elimination of the requirements to consider whether an underlying event or transaction is extraordinary, but retains the presentation and disclosure guidance for items that are unusual in nature or occur infrequently and expands upon it to include items that are both unusual in nature and infrequently occurring. This guidance is effective prospectively or retrospectively for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We expect that this guidance will have no impact on our consolidated financial position or results of operations upon adoption.

Revenue Recognition

In May 2014, the FASB issued an accounting standards update for the recognition of revenue, which supersedes existing revenue recognition requirements and most industry-specific guidance. The update provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective for annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2017 under either full or modified retrospective adoption. Early application is permitted only as of annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2016. We are currently assessing the potential impact this guidance may have on our consolidated financial statements as a result of adopting this standard.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Management’s Estimates and Assumptions

Preparation of our consolidated financial statements in accordance with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the accounting for and recognition and disclosure of assets, liabilities, equity, revenues and expenses. We must make these estimates and assumptions because certain information that we use is dependent on future events, cannot be calculated with a high degree of precision given the available data or simply cannot be readily calculated. In 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 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. In the opinion of management, these consolidated financial statements include all adjustments, which include normal recurring and nonrecurring adjustments, necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented. Actual results may differ materially from the estimates and assumptions that we use in the preparation of our consolidated financial statements.

Change in Fiscal Year

In June 2014, we elected to change our fiscal year-end from April 30^th to December 31^st. This change in fiscal year became effective for our fiscal year beginning January 1, 2015 and ended December 31, 2015. As a result of this change, we filed a Transition Report on Form 10-KT for the eight-month transition period ended December 31, 2014. The references in these notes to the consolidated financial statements to the terms below reflect the respective reporting periods presented in the consolidated financial statements:

Term	Financial Reporting Period
fiscal year 2015	January 1, 2015 through December 31, 2015
transition period 2014	May 1, 2014 through December 31, 2014
fiscal year 2014	May 1, 2013 through April 30, 2014
fiscal year 2013	May 1, 2012 through April 30, 2013

Cash and Cash Equivalents

We consider all highly liquid investments purchased with original maturities of three months or less to be cash equivalents.

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents, restricted cash, accounts receivable-trade and derivative instruments. We maintain cash and cash equivalents and restricted cash 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-trade is limited because our customer base is comprised of a large number of geographically diverse customers, thus reducing the credit risk associated with any one customer group. As of December 31, 2015 no single customer or customer group represented greater than 5% of total accounts receivable-trade. We manage credit risk through credit evaluations, credit limits, monitoring procedures and, at times, credit insurance, but generally do not require collateral to support accounts receivable -trade. 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 – Trade, Net of Allowance for Doubtful Accounts

Accounts receivable – trade represent receivables from customers for collection, transfer, recycling, disposal and other services. Our accounts receivable – trade 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 – trade, 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 trends, credit policy and a review of our accounts receivable – trade by aging category. Our reserve is evaluated and revised on a monthly basis. Past-due accounts receivable-trade are written off when deemed to be uncollectible. As of December 31, 2015, $44,707 of our accounts receivable – trade served as eligible collateral under our senior secured asset-based revolving credit and letter of credit facility (“ABL Facility”).

Inventory

Inventory 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. As of December 31, 2015, $219 of our recyclables ready for sale served as eligible collateral under our ABL Facility.

Property, Plant and Equipment

Property, 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 Classification	Estimated Useful Life
Buildings and improvements		10-30 years
Machinery and equipment		5-10 years
Rolling stock		5-10 years
Containers		5-12 years
Furniture and Fixtures		3-8 years

The 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 disclosure over the amortization of landfill development costs and Note 6, Property, Plant and Equipment for disclosure over property, plant and equipment.

Landfill Accounting

Life Cycle Accounting

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 our landfills, preparation costs include the total estimated costs to complete construction of the landfills’ permitted and expansion capacity.

Landfill Development Costs

We 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 fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013 was $62, $333, $256 and $368, respectively.

Landfill Airspace

We 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.

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 the measured density obtained from previous 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 the landfill 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 Costs

The 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.

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, lawyers, accounting personnel and consultants, 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 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 (2.0% as of December 31, 2015). 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, 2015 is between approximately 9.1% and 9.5%, 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 $3,370, $2,275, $3,967 and $3,538 in fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, 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 8, Final Capping, Closure and Post-Closure Costs for disclosure over final capping, closure and post-closure costs asset retirement obligations.

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 cash. Surety bonds securing closure and post-closure obligations at December 31, 2015, December 31, 2014 and April 30, 2014 totaled $156,163, $144,633 and 133,847, respectively. Letters of credit securing closure and post-closure obligations as of December 31, 2015, December 31, 2014 and April 30, 2014 totaled $1,000, $1,104 and $1,104, respectively. See Note 5, Restricted Cash / Restricted Assets for disclosure over restricted cash securing closure and post-closure obligations.

Landfill Operating Lease Contracts

We entered into three landfill operation and management agreements in the fiscal year ended April 30, 2004 and one landfill operation and management agreement in the fiscal year ended April 30, 2006. 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 liabilities. 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 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. See Note 6, Property, Plant and Equipment for disclosure over depletion of landfill operating lease contracts.

Leases

We lease property and equipment in the ordinary course of our business. Our most significant lease obligations are for property and equipment specific to our industry. Our leases have varying terms. Some may include renewal or purchase options, escalation clauses, restrictions, lease concessions, capital project funding, penalties or other obligations that we consider in determining minimum rental payments. Leases are classified as either operating leases or capital leases, as appropriate.

Operating Leases. Many of our leases are operating leases. This classification generally can be attributed to either (i) relatively low fixed minimum rental payments or (2) minimum lease terms that are much shorter than the assets’ economic useful lives. We expect that, in the normal course of business, our operating leases will be replaced by other leases, or replaced with fixed asset expenditures. See Note 10, Commitments and Contingencies for disclosure over future minimum lease payments related to our operating leases.

Capital Leases. We capitalize assets acquired under capital leases at the inception of each lease and amortize them to depreciation expense over the lesser of the useful life of the asset or the lease term, as appropriate. The present value of the related lease payments is recorded as a debt obligation. See Note 9, Long-Term Debt and Capital Leases for disclosure over our future maturities of debt, which includes capital lease payments.

Goodwill and Intangible Assets

Goodwill. 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 7,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 7, Goodwill and Intangible Assets for disclosure over intangible assets.

Investments in Unconsolidated Entities

Investments 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, 2015, December 31, 2014 and April 30, 2014, we had no investments accounted for under the equity 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. Additionally, 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. See “Asset Impairments” accounting policy below and Note 12, Fair Value of Financial Instruments for further disclosure over our investments.

Equity Method Investments

GreenFiber. In the fiscal year ended April 30, 2001, we entered into a joint venture agreement with Louisiana-Pacific Corporation (“LP”) to combine our respective cellulose insulation businesses into a single operating entity, US GreenFiber LLC (“GreenFiber”). In fiscal year 2014, we and LP executed a purchase and sale agreement with a limited liability company formed by Tenex Capital Partners, L.P., pursuant to which we and LP agreed to sell our membership interests in GreenFiber for total cash consideration of $18,000 plus an expected working capital true up less any indebtedness and other unpaid transaction costs of GreenFiber as of the closing date. The transaction was completed in fiscal year 2014 for $19,194 in gross cash proceeds, including a $1,194 working capital adjustment. After netting indebtedness of GreenFiber and transaction costs, our portion of the net cash proceeds based on our 50% membership interest amounted to $3,442. After considering the $593 impact of our unrealized losses relating to derivative instruments in accumulated other comprehensive loss on our investment in GreenFiber, we recorded a gain on sale of equity method investment of $593 in fiscal year 2014. We had previously accounted for our 50% membership interest in GreenFiber using the equity method of accounting.

Tompkins. In the fiscal year ended April 30, 2012, we finalized the terms of a joint venture agreement with FCR, LLC (“FCR”) to form Tompkins County Recycling LLC (“Tompkins”), a joint venture that operates a material recovery facility (“MRF”) located in Tompkins County, New York and processes and sells commodities delivered to the Tompkins MRF. In fiscal year 2014, we purchased the remaining 50% membership interest of Tompkins for total cash consideration of $425. The acquisition-date fair value of our investment in Tompkins, which was determined using the cost approach based on an assessment of the price to purchase the acquired assets of Tompkins, prior to the acquisition date was $300. We recognized a $106 gain through loss from equity method investments due to the remeasurement in fiscal year 2014. As a result of the purchase, we no longer account for our investment in Tompkins using the equity method of accounting and began including the results of Tompkins in our consolidated financial statements.

Fair Value of Financial Instruments

Our financial instruments include cash and cash equivalents, accounts receivable-trade, restricted cash and investments held in trust on deposit with various banks as collateral for our obligations relative to our landfill final capping, closure and post-closure costs and 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 9, Long-Term Debt and Capital Leases and Note 12, 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 Combinations

We 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 4, Business Combinations for disclosure over business acquisitions.

Environmental Remediation Liabilities

We 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 10, Commitments and Contingencies for disclosure over environmental remediation liabilities.

Self-Insurance Liabilities and Related Costs

We are self-insured for vehicles and workers’ compensation with reinsurance coverage limiting our maximum exposure. Our maximum exposure in fiscal year 2015 under the workers’ compensation plan is $1,000 per individual event. Our maximum exposure in fiscal year 2015 under the automobile plan is $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 actuarially determined liability is calculated based on historical data, which considers both the frequency and settlement amount of claims. Our self-insurance reserves totaled $11,560, $10,863 and $10,280 as of December 31, 2015, December 31, 2014 and April 30, 2014, 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 Taxes

We 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. See Note 14, Income Taxes for disclosure related to income taxes.

Derivatives and Hedging

We 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 also 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 effective cash flow hedges, the change in the fair value of these derivatives is recorded in our stockholders’ equity (deficit) as a component of accumulated other comprehensive income (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 are 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, 2015.

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 effective cash flow hedges, the change in fair value is recorded in our stockholders’ equity (deficit) as a component of accumulated other comprehensive income (loss) and included in interest expense at the same time as interest expense is affected by the hedged transaction. Differences paid or received over the life of the agreements are recorded as additions to or reductions of interest expense on the underlying debt. We were not party to any interest rate derivative agreements deemed to be effective cash flow hedges as of December 31, 2015.

For interest rate derivatives deemed to be ineffective cash flow hedges, the change in fair value is recorded through earnings and included in loss (gain) on derivative instruments. We are currently party to one interest rate swap deemed to be an ineffective cash flow hedge that is scheduled to mature on March 15, 2016 and were party to another interest rate swap deemed to be an ineffective cash flow hedge that was settled in fiscal year 2015 for $830 in conjunction with the refinancing of our senior revolving credit and letter of credit facility that was due March 18, 2016 (“Senior Credit Facility”). See Note 12, Fair Value of Financial Instruments for fair value disclosure over derivative instruments.

Contingent Liabilities

We 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 10, Commitments and Contingencies for disclosure over loss contingencies. 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 4, Business Combinations for disclosure over a contingent liability assumed as part of the acquisition of a business.

Revenue Recognition

We recognize collection, transfer, recycling and disposal revenues as the services are provided. Certain customers are billed in advance and, accordingly, recognition of the related revenues is deferred until the services are provided.

Revenues from the sale of recycled materials are recognized upon shipment. Rebates to certain municipalities based on sales of recyclable materials are recorded upon the sale of such recyclables to third-parties and are included as a reduction of revenues. Revenues for processing of recyclable materials are recognized when the related service is provided. Revenues from the brokerage of recycled materials are recognized on a net basis at the time of shipment.

Asset Impairments

Recovery 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, and identifiable intangible 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 15, Other Items and Charges for disclosure related to long-lived asset impairments recognized during the reporting periods.

Goodwill. We annually assess goodwill impairment at the end of our fiscal year or more frequently if events or circumstances indicate that impairment may exist. Historically, we have performed our annual goodwill impairment test using our fiscal year-end, or April 30^th, as the measurement date. Effective with the change in our fiscal year-end from April 30^th to December 31^st, we have voluntarily changed our goodwill impairment measurement date from April 30^th to December 31^st to coincide with the change in our fiscal year-end. The voluntary change in our goodwill impairment measurement date was applied prospectively as it represents the modification of an existing principle based on new facts and circumstances.

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 capitalization.

If the fair value of the 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 in fiscal year 2015. As of December 31, 2015, the Step 1 testing for goodwill impairment performed for the 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 the Eastern, Western, Recycling and Customer Solutions reporting units exceeded its carrying value by in excess of 22.9%. We incurred no impairment of goodwill as a result of our annual goodwill impairment tests in fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013. However, there can be no assurance that goodwill will not be impaired at any time in the future.

Cost Method Investments. As of December 31, 2015, we owned 5.3% of the outstanding common stock of Recycle Rewards, Inc. (“Recycle Rewards”), a company that markets an incentive based recycling service. In both fiscal year 2015 and transition period 2014, 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 2015, and had a valuation analysis performed by a third-party valuation specialist in transition period 2014, both of 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 these analyses, it was determined in each case that the fair value of our cost method investment in Recycle Rewards was less than the carrying amount and, therefore, we recorded other-than-temporary investment impairment charges of $1,090 and $2,320 in fiscal year 2015 and transition period 2014, respectively. As of December 31, 2015, the carrying amount of our cost method investment in Recycle Rewards was $1,070.

As of December 31, 2015, we owned 9.8% of the outstanding equity value of GreenerU, Inc. (“GreenerU”), a services company focused on providing energy efficiency, sustainability and renewable energy solutions to colleges and universities. In fiscal year 2015, it was determined based on the operating performance and recent indications of third-party interest in GreenerU that our cost method investment in GreenerU was potentially impaired. A valuation analysis was performed by a third-party valuation specialist using a market approach based on an option pricing methodology to determine an equity value and fair market value per share for GreenerU. Based on this analysis, it was determined that the fair value of our cost method investment in GreenerU was less than the carrying amount and, therefore, we recorded an other-than-temporary investment impairment charge of $691 in fiscal year 2015. As of December 31, 2015, the carrying amount of our cost method investment in GreenerU was $309.

As of December 31, 2015, we owned 17.0% and 16.2% of the outstanding common stock of AGreen Energy LLC (“AGreen”) and BGreen Energy LLC (“BGreen”), respectively. In fiscal year 2015, AGreen and BGreen, both of which we account for as cost method investments, entered into agreements that resulted in the contribution and sale of certain assets and liabilities of AGreen and BGreen to a limited liability company in exchange for partial ownership interests in a parent of that limited liability company. As a result of the transactions, we performed an analysis to determine whether an other-than-temporary impairment in the carrying value of our cost method investments had occurred. Based on the analysis performed, which measured the fair value of our cost method investments using an in-exchange valuation premise under the market approach that utilized the estimated purchase consideration received, we recorded an investment impairment charge of $318 in fiscal year 2015. As of December 31, 2015, the carrying amount of our cost method investment in AGreen and BGreen was $297.

Stock-Based Compensation

All 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. Stock-based compensation expense is based on the number of awards ultimately expected to vest and is therefore reduced for an estimate of the awards that are expected to be forfeited prior to vesting.

The fair value of each stock option 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 option holders will retain their vested stock options before exercising them and the estimated volatility of our common stock price over the expected term.

See Note 11, Stockholders Deficit for disclosure over stock-based compensation.

Earnings per Share

Basic earnings per share is computed by dividing the net loss from continuing operations attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated based on the combined weighted average number of common shares and potentially dilutive shares, which include, where appropriate, the assumed exercise of employee stock options, unvested restricted stock awards, unvested restricted stock units and unvested performance stock units. In computing diluted earnings per share, we utilize the treasury stock method. See Note 17, Earnings Per Share for disclosure over the calculation of earnings per share.

Discontinued Operations

We analyze our operations that have been divested or classified as held-for-sale to determine if they qualify for discontinued operations accounting. A component of an entity, a group of components of an entity, or a business is required to be reported in discontinued operations once it meets the held for sale criteria, is disposed of by sale, or is disposed of other than by sale. A disposal is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. See Note 16,Divestiture Transactions and Discontinued Operations for disclosure over discontinued operations.

Subsequent Events

Except as disclosed, no material subsequent events have occurred since December 31, 2015 through the date of this filing that would require recognition or disclosure in our current period consolidated financial statements.

4. BUSINESS COMBINATIONS

We acquired various businesses during transition period 2014, fiscal year 2014 and fiscal year 2013, including several solid waste hauling operations, a transfer station, a MRF and an industrial service management business (included in the Other segment). 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, except amounts related to the acquisition of Bestway Disposal Services and BBI Waste Services (“BBI”) in fiscal year 2013, are expected to be deductible for tax purposes. See Note 14, Income Taxes for disclosure over the tax impact associated with the acquisition of BBI. We did not acquire any businesses during fiscal year 2015.

The purchase price paid for these acquisitions and the allocation of the purchase price is as follows:

(1) In fiscal year 2014, we recovered a portion of the purchase price holdback amount we had previously paid and were relieved of any potential contingent consideration obligation associated with the acquisition of an industrial service management business completed earlier in fiscal year 2014. As a result, we recorded a $1,058 gain on settlement of acquisition related contingent consideration in fiscal year 2014.

The following unaudited pro forma combined information shows our operational results as though each of the acquisitions completed in transition period 2014, fiscal year 2014 and fiscal year 2013 had occurred as of May 1, 2012.

Final Capping, Closure and Post-Closure Costs

8. FINAL CAPPING, CLOSURE AND POST-CLOSURE COSTS

Accrued final capping, closure and post-closure costs include the current and non-current portion of costs associated with obligations for final capping closure and post-closure of our landfills. We estimate our future final capping, closure and post-closure costs in order to determine the final capping, closure and post-closure expense per ton of waste placed into each landfill as further described in Note 3, Summary of Significant Accounting Policies to these consolidated financial statements. The anticipated timeframe 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 changes to accrued final capping, closure and post-closure liabilities are as follows:

ABL Facility

In fiscal year 2015, we issued an additional $60,000 aggregate principal amount of 7.75% senior subordinated notes due February 15, 2019 (“2019 Notes”). The additional 2019 Notes, which are fungible with and issued under the same indenture as the $325,000 2019 Notes previously issued, were issued at a discount of approximately $476 to be accreted over the remaining term of the 2019 Notes. We used the net proceeds from this issuance, together with the initial borrowings under our new ABL Facility, to refinance our Senior Credit Facility.

Our ABL Facility consists of a revolving credit facility with loans thereunder being available up to an aggregate principal amount of $190,000, subject to availability under a borrowing base formula as defined in the ABL Facility agreement. We have the right to request, at our discretion, an increase in the amount of loans under the ABL Facility by an aggregate amount of $100,000, subject to the terms and conditions set forth in the ABL Facility agreement. Interest accrues at one month LIBOR plus between 1.75% and 2.50%, subject to the terms of the ABL Facility agreement and is set at LIBOR plus 2.25% as of December 31, 2015. The ABL Facility matures on February 26, 2020. If we fail to refinance the 2019 Notes on or before November 16, 2018, the maturity date for the ABL Facility will be November 16, 2018. The ABL Facility is guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries and is collateralized by certain qualified accounts receivable, trade, inventory and property, plant and equipment. As of December 31, 2015, our borrowing availability under the ABL Facility was $64,112 and was calculated as a borrowing base of $148,473, less revolver borrowings of $57,422, less outstanding irrevocable letters of credit totaling $26,939, at which date no amount had been drawn.

The ABL Facility requires us to maintain a certain minimum consolidated EBITDA measured at the end of each fiscal quarter. Additionally, if borrowing availability does not meet certain thresholds as defined in the ABL Facility agreement, the ABL Facility requires us to meet additional covenants, including, without limitation:

• a minimum fixed charge coverage ratio; and

• a maximum consolidated first lien funded debt 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 ABL 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 ABL 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 Financings

New York Bonds. In transition period 2014, we completed a financing transaction involving $25,000 in aggregate principal amount of New York State Environmental Facilities Corporation Solid Waste Disposal Revenue Bonds Series 2014 (“New York Bonds”). We borrowed the proceeds of the New York Bonds to repay borrowings under our Senior Credit Facility for qualifying property, plant and equipment assets purchased in the state of New York.

As of December 31, 2015, we had outstanding $25,000 aggregate principal amount of senior unsecured New York Bonds.

During the fixed interest rate period, the New York Bonds will not be supported by a letter of credit. Interest is payable on June 1 and December 1 of each year. An additional $15,000 aggregate principal amount of New York Bonds may be offered under the same indenture in the future. The New York Bonds mature on December 1, 2044.

In fiscal year 2015, we completed a financing transaction involving the issuance by the Finance Authority of Maine of $15,000 aggregate principal amount of Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2015 (“FAME Bonds 2015”). We borrowed the proceeds of the offering of the FAME Bonds 2015 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 for the costs of the issuance of the FAME Bonds 2015.

As of December 31, 2015, we had outstanding $15,000 aggregate principal amount of senior unsecured FAME Bonds 2015. The FAME Bonds 2015, which are and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 5.125% per annum through August 1, 2025, at which time they may be converted from a fixed to a variable rate. During the fixed interest rate period, the FAME Bonds 2015 will not be supported by a letter of credit. Interest is payable semiannually in arrears on February 1 and August 1 of each year. An additional $15,000 aggregate principal amount of FAME Bonds 2015 may be offered under the same indenture in the future. The FAME Bonds 2015 mature on August 1, 2035.

Vermont Bonds. As of December 31, 2015, we had outstanding $16,000 aggregate principal amount of senior unsecured Vermont Economic Development Authority Solid Waste Disposal Long-Term Revenue Bonds Series 2013 (“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 4.75% per annum through April 1, 2018, at which time they may be converted from a fixed rate to a variable rate. During the fixed interest rate period, the Vermont Bonds will not be supported by a letter of credit. Interest is payable semiannually in arrears on April 1 and October 1 of each year. The Vermont Bonds mature on April 1, 2036. We borrowed the proceeds of the Vermont Bonds to repay borrowings under our Senior Credit Facility for qualifying property, plant and equipment assets purchased in the state of Vermont.

New Hampshire Bonds. In transition period 2014, we completed a financing transaction involving $11,000 aggregate principal amount of tax-exempt Solid Waste Disposal Revenue Bonds Series 2013 issued by the Business Finance Authority of the State of New Hampshire (“New Hampshire Bonds”), consisting of the conversion and remarketing of $5,500 principal amount New Hampshire Bonds from a variable rate to a fixed term rate and the issuance of an additional $5,500 principal amount fixed term rate New Hampshire Bonds.

As of December 31, 2015, we had outstanding $11,000 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 4.00% per annum through October 1, 2019, at which time they may be converted from a fixed rate to a variable rate.

The New Hampshire Bonds mature on April 1, 2029. We borrowed the proceeds of the New Hampshire Bonds to repay borrowings under our Senior Credit Facility for qualifying property, plant and equipment assets purchased in the state of New Hampshire.

Senior Subordinated Notes

In fiscal year 2015, we issued an additional $60,000 aggregate principal amount of 2019 Notes. The additional 2019 Notes, which are both fungible and issued under the same indenture as the $325,000 2019 Notes previously issued, were issued at a discount of $476 to be accreted over the remaining term of the 2019 Notes. We used the net proceeds from this issuance, together with the initial borrowings under our new ABL Facility, to refinance our Senior Credit Facility. Additionally, in fiscal year 2015 we repurchased and permanently retired $14,700 aggregate principal amount of 2019 Notes at a weighted average repurchase price of $101.0 in order to maximize interest savings by paying down our most expensive debt.

As of December 31, 2015, we had outstanding $370,300 aggregate principal amount of 2019 Notes, which will mature on February 15, 2019. The 2019 Notes accrue interest at the rate of 7.75% per annum and interest is payable semiannually in arrears on February 15 and August 15 of each year. The 2019 Notes are fully and unconditionally guaranteed on a senior subordinated basis by substantially all of our existing and future domestic restricted subsidiaries that guarantee our ABL Facility.

The indenture governing the 2019 Notes contains certain negative covenants which restrict, among other things, our ability to sell assets, make investments in joint ventures, pay dividends, repurchase stock, incur debt, grant liens and issue preferred stock. As of December 31, 2015, we were in compliance with all covenants under the indenture governing the 2019 Notes, and we do not believe that these restrictions impact our ability to meet future liquidity needs except that they may impact our ability to increase our investments in non-wholly owned entities, including the joint ventures to which we are already party.

Loss on Debt Extinguishment

Senior Subordinated Notes. In fiscal year 2015, we repurchased and permanently retired $14,700 aggregate principal amount of 2019 Notes at a weighted average repurchase price of $101.0 in order to maximize interest savings by paying down our most expensive debt. As a result of the repurchase, we recorded a charge of $478 in fiscal year 2015 as a loss on debt extinguishment primarily related to the non-cash write off of deferred financing costs and unamortized original issue discount in proportion with the settlement amount.

Senior Credit Facility. In fiscal year 2015, we recorded a charge of $521 as a loss on debt extinguishment related to the write-off of deferred financing costs in connection with changes to the borrowing capacity from the Senior Credit Facility to the ABL Facility. The remaining unamortized deferred financing costs of the Senior Credit Facility, along with fees paid to the creditor and third-party costs incurred for the ABL Facility, are to be amortized over the term of the ABL Facility.

Second Lien Notes. In fiscal year 2013, we recorded a charge of $15,584 as a loss on debt extinguishment related to the full refinancing of our 11.0% senior second lien notes (“Second Lien Notes”). The loss on debt extinguishment consisted of a $2,767 non-cash write off of deferred financing costs, a $2,074 non-cash write off of the unamortized original issue discount and a $10,743 charge associated with the early tender premium and tender fees associated with the redemption of the Second Lien Notes.

Fair Value of Debt

As of December 31, 2015, the fair value of our fixed rate debt, including our 2019 Notes, FAME Bonds 2005R-2, FAME Bonds 2015, Vermont Bonds, New York Bonds and New Hampshire Bonds was approximately $458,775 and the carrying value was $458,700. The fair value of the 2019 Notes are considered to be Level 1 within the fair value hierarchy as the fair value is based off of a quoted market price in an active market. The fair value of the FAME Bonds 2005R-2, the FAME Bonds 2015, the Vermont Bonds, the New York Bonds and the New Hampshire Bonds is considered to be Level 2 within the fair value hierarchy as the fair value is determined using market approach pricing provided by a third-party that utilizes pricing models and pricing systems, mathematical tools and judgment to determine the evaluated price for the security based on the market information of each of the bonds or securities with similar characteristics.

Although we have determined the estimated fair value amounts of the FAME Bonds 2005R-2, the FAME Bonds 2015, the Vermont Bonds, the New York Bonds and the 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. As of December 31, 2015, the fair value of our ABL Facility approximated its carrying value of $57,422 based on current borrowing rates for similar types of borrowing arrangements, or Level 2 inputs. The carrying value of our remaining material variable rate debt, the FAME Bonds 2005R-1, approximates fair value because the interest rate for the debt instrument is based on a market index that approximates current market rates for instruments with similar risk and maturities.

Future Maturities of Debt

Aggregate principal maturities of long-term debt and capital leases are as follows:

Estimated Future Payments as of December 31, 2015:

Commitments and Contingencies

10. COMMITMENTS AND CONTINGENCIES

Lease Commitments

We lease operating facilities and equipment in the ordinary course of our business under various operating leases with monthly payments varying up to $36. Future minimum rental payments are recognized on a straight-line basis over the minimum lease term. Total rent expense under operating leases charged to operations was $9,392, $4,868, $5,651 and $5,372 in fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, respectively.

Future minimum rental payments under non-cancellable operating leases, which include landfill operating leases, are as follows:

2020		13,218
Thereafter		117,224
Total minimum lease payments	$	200,344

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 alleging environmental damage or violations of the permits and licenses pursuant to which we operate. In addition, we have been 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 Accounting Standards Codification (“ASC”) 450-20, 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.

Expera Old Town, LLC v. Casella Waste Systems, Inc.

On or about November 6, 2015, Expera Old Town, LLC (“Expera”) filed a lawsuit against us in Maine Superior Court, seeking damages for breach of contract and unjust enrichment, and an action for declaratory judgment (the “Lawsuit”). Expera was a successor-in-interest to a contract between us and Old Town Fuel and Fiber (“OTFF”), the former owner of a pulp manufacturing facility (“Facility”) located in Old Town, Maine (the “Contract”). Expera purchased the Facility during the pendency of the bankruptcy of OTFF. Since the filing of the Lawsuit, Expera has sold the Facility and related assets, to MFGR LLC (“MFGR”). MFGR continues to allege that we have the obligation to provide a specialized type of wood fuel to the Facility or, alternatively, that we owe a “Fuel Replacement Fee” of up to $2,000 a year (subject to the possibility of certain credits against such payments). The Contract expires in 2036. We believe we have meritorious defenses to each of the claims in the Lawsuit, are vigorously contesting these allegations, and have filed a counter claim for funds owed to us by MFGR or Expera.

On or about February 10, 2016, we reached an agreement in principle with MFGR to dismiss this suit with prejudice, and to resolve all outstanding claims of any nature including future claims which could arise under the Contract. The Parties are endeavoring in good faith to enter into a settlement agreement (“SA”) and ancillary agreements. Pursuant to the pending SA, we will pay MFGR $1,250 upon execution of the SA, and $350 a year for five years following execution of the SA. Accordingly, taking into account the net present value of the settlement payments, we have recorded a reserve of $2,616 as of December 31, 2015. This includes a contract settlement charge of $1,940 and $676 of operating expenses recorded in fiscal year 2015. We also reserved $75 as of December 31, 2015 for legal costs associated with the Lawsuit and SA.

We will also enter into a new leachate disposal agreement at market prices with MFGR for the treatment of leachate from the landfill managed by us for the State of Maine located in Old Town, Maine (“Juniper Ridge”), and MFGR will enter into a waste disposal agreement at market prices with us for the disposal at the Juniper Ridge of waste materials produced in the demolition or re-purposing of the Facility.

Greenwood Street Landfill, Worcester, Massachusetts

On July 2, 2014, we received a draft Administrative Consent Order with Penalty and Notice of Noncompliance (“Draft Order”) from the Massachusetts Department of Environmental Protection (“MADEP”) alleging that a subsidiary, NEWS of Worcester, LLC, had completed substantive closure of a portion of the Greenwood Street Landfill in Worcester, Massachusetts in 2010, at an elevation exceeding the applicable permit condition. While we neither admitted nor denied the allegations in the Draft Order, a final Administrative Consent Order with Penalty and Notice of Noncompliance was executed on March 20, 2015 (“Final Order”), and we agreed to pay a civil administrative penalty in a total amount of $172. MADEP agreed that $129 of that amount could be paid as a Supplemental Environmental Project (“SEP”) for work being done by the Massachusetts Audubon Society at the Broad Meadow Brook Conservation Center & Wildlife Sanctuary in Worcester, Massachusetts. This SEP has been paid in full.

Environmental Remediation Liability

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 matter represents our outstanding material claim.

Potsdam Environmental Remediation Liability

On December 20, 2000, the State of New York Department of Environmental Conservation (“DEC”) issued an Order on Consent (“Order”) which named Waste-Stream, Inc. (“WSI”), our subsidiary, General Motors Corporation (“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 15% participant share. It is unlikely that any significant expenditures relating to onsite remediation will be incurred until the fiscal year ending December 31, 2017. 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 1.8%. The changes to the environmental remediation liability associated with the Potsdam environmental remediation liability are as follows:

	Fiscal Year Ended		Eight Months Ended			Fiscal Year Ended
	December 31, 2015		December 31, 2014			April 30, 2014
Beginning balance	$	5,142	$	5,320		$	5,297

Accretion expense		79		92			138
Payments		—		(270	)		(28	)
Ending balance	$	5,221	$	5,142		$	5,320

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:

Estimated Future Environmental Remediation Payments as of December 31, 2015:
2016	$	273

2018		855
2019		40
2020		25
Thereafter		749
Total	$	5,198

A 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	$	5,198
Plus inflation		23
Liability balance - December 31, 2015	$	5,221

Any 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.

Employment Contracts

We have entered into employment contracts with four of our executive officers. The contracts are dated June 18, 2001, March 31, 2006, July 6, 2010 and September 1, 2012. 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 $1,425. 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.

Equity [Abstract]

Stockholders' Deficit

11. STOCKHOLDERS’ DEFICIT

Common Stock

The 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.

In fiscal year 2013, we sold 11,500 shares of Class A common stock at an average price of $4.00 per share in a registered public offering. The net proceeds received from the registered public offering, after deducting underwriting discounts, commissions and offering expenses, were $42,184 and were used to refinance our Second Lien Notes.

Preferred Stock

We are authorized to issue up to 944 shares of preferred stock in one or more series. As of December 31, 2015 and December 31, 2014 we had no shares issued.

Stock Based Compensation

Stock Incentive Plans

1997 Stock Option Plan. In the fiscal year ended April 30, 1998, we adopted the 1997 Stock Option Plan (“1997 Plan”) a stock option plan for employees, officers and directors of, and consultants and advisors to us. The 1997 Plan terminated as of July 31, 2007 and as a result no additional awards may be made pursuant to the 1997 Plan.

2006 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. Under the 2006 Plan, we may grant awards up to an aggregate amount of shares equal to the sum of: (i) 2,475 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 as were subject to options granted under our 1993 Incentive Stock Option Plan, 1994 Non-statutory Stock Option Plan, 1996 Stock Option Plan, and 1997 Plan (“Prior Plans”), which were not actually issued under the Prior Plans because such stock options expire or otherwise result in shares not being issued. As of December 31, 2015, there were 956 Class A common stock equivalents available for future grant under the 2006 Plan, inclusive of additional Class A common stock equivalents that were previously issued under our terminated plans and have become available for grant because such awards expired or otherwise resulted in shares not being issued. No award may be granted under the 2006 Plan after October 10, 2016 and accordingly we expect to implement a new stock incentive plan which would be recommended to stockholders for approval at the 2016 Annual Meeting of Stockholders.

Stock options granted under the 2006 Plan are granted at a price equal to the prevailing fair market 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 to four year period from the date of grant.

We grant restricted stock awards, restricted stock units and performance stock units under the 2006 Plan at a price equal to the fair market value of our Class A common stock at the date of grant. Restricted stock awards granted to non-employee directors vest incrementally over a three year period beginning on the first anniversary of the date of grant. Restricted stock units vest incrementally over an identified service period beginning on the grant date based on continued employment. Performance stock units vest at a future date following the grant date and are based on the attainment of a performance target.

Stock Options

The following table summarizes stock option activity:

						Weighted

During fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, stock-based compensation expense for stock options was $671, $386, $464, and $528, respectively.

During fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, the aggregate intrinsic value of stock options exercised was $52, $31, $23 and $0.

As of December 31, 2015, total unrecognized stock-based compensation expense related to outstanding stock options was $1,225, which will be recognized over a weighted average period of 2.3 years.

Our calculation of stock-based compensation expense associated with stock options granted was made using the Black-Scholes valuation model. The weighted average fair value of stock options granted during fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013 were $5.35, $3.62, $4.22 and $3.03 per option, respectively, which were calculated assuming no expected dividend yield using the following weighted average assumptions:

	Fiscal Year Ended		Eight Months Ended		Fiscal Year Ended April 30,
	December 31, 2015		December 31, 2014		2014		2013
Expected life		7.24 years		7.00 years		6.79 years		6.82 years
Risk-free interest rate		2.02%		2.15%		2.22%		1.14%
Expected volatility		81.31%		82.76%		83.96%		84.40%

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.

The Black-Scholes valuation model requires extensive use of accounting judgment and financial estimation, including estimates of the expected term option holders will retain their vested stock options before exercising them, the estimated volatility of our Class A common stock price over the expected term and the number of stock options that will be forfeited prior to the completion of their vesting requirements. 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.

During fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, stock-based compensation expense related to restricted stock, restricted stock units and performance stock units was $2,314, $1,202, $1,861 and $1,609, respectively. Stock-based compensation expense related to restricted stock and restricted stock units during fiscal year 2015 included $270 of incremental compensation expense resulting from the modification of restricted stock awards associated with the retirement of two members of our Board of Directors. There was $19, $0, $0 and $0 of tax benefit in the provision for income taxes associated with stock-based compensation expense during fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013.

During fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, the total fair value of other stock awards vested was $2,340, $1,866, $1,458 and $2,475, respectively.

As of December 31, 2015, total unrecognized stock-based compensation expense related to restricted stock and restricted stock units was $2,674, which will be recognized over a weighted average period of 1.8 years. We recorded a tax benefit of $185, $84, $0 and $96 to additional paid-in-capital related to the exercise of various share based awards in fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, respectively. Tax savings from stock-based compensation resulting from tax deductions in excess of expense are reflected as a financing cash flow in our consolidated financial statements.

We also recorded $94, $52, $79 and $99 of stock-based compensation expense related to our Amended and Restated 1997 Employee Stock Purchase Plan during fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, respectively.

Accumulated Other Comprehensive Income

Accumulated other comprehensive income is a component of stockholders’ deficit included in the accompanying consolidated balance sheets and includes, as applicable, the effective portion of changes in the fair value of our cash flow hedges that consist of commodity hedges and interest rate swaps, the changes in fair value of our marketable securities, as well as our portion of the changes in the fair value of GreenFiber’s commodity hedges up until the date of divestiture.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

12. FAIR VALUE OF FINANCIAL INSTRUMENTS

We use a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. These tiers include: Level 1, defined as quoted market prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; and Level 3, defined as unobservable inputs that are not corroborated by market data.

We use valuation techniques that maximize the use of market prices and observable inputs and minimize the use of unobservable inputs. In measuring the fair value of our financial assets and liabilities, we rely on market data or assumptions which we believe market participants would use in pricing an asset or a liability.

Assets and Liabilities Accounted for at Fair Value on a Recurring Basis

Our financial instruments include cash and cash equivalents, restricted investments 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, trade receivables, interest rate derivatives, trade payables and long-term debt. The carrying values of cash and cash equivalents, trade receivables and trade payables approximate their respective fair values due to their short-term nature. The fair value of restricted investments held in trust and escrow accounts is included as restricted assets in the Level 1 tier below, along with restricted cash reserved for repayment of costs incurred to fund certain capital projects.

The fair value of the interest rate derivative as of December 31, 2015, included in the Level 2 tier below, is calculated based on a valuation obtained from our counter-party based primarily on the three month LIBOR yield curve that is observable at commonly quoted intervals for the full term of the swap. Previously, it was calculated by us based on the three month LIBOR yield curve that is observable at commonly quoted intervals for the full term of the swap, adjusted by the credit risk of our counter-party and us based on observable credit default swap rates. The change in valuation method is due to the immaterial credit risk impact of our counter-party and us based on the short term nature of the interest rate swap, which matures on March 15, 2016. We recognize all derivatives on the balance sheet at fair value. See Note 9, Long-Term Debt and Capital Leases for disclosure over the fair value of debt.

The fair value of our cost method investment in GreenerU was measured by a third-party valuation specialist who completed a valuation analysis using a market approach based on an option pricing methodology that considers comparable publicly traded companies revenue multiples to determine an equity value and fair market value per share for GreenerU, which we used to properly value our cost method investment in GreenerU. The fair value of our cost method investment in RecycleRewards was measured by us when we completed a valuation analysis using 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.

13. EMPLOYEE BENEFIT PLANS

Defined Contribution Plan

We 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 ratably over a three year period. Employer contributions for fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013 amounted to $1,033, $497, $784 and $645, respectively.

Employee Stock Purchase Plan

In the fiscal year ended April 30, 1998, we implemented our 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. An aggregate of 1,200 shares of Class A common stock were initially reserved for this purpose. During fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, 80, 79, 70 and 76 shares, respectively, of Class A common stock remained issued under this plan. As of December 31, 2015, 255 shares of Class A common stock were available for distribution under this plan.

Included in the current state tax provision for fiscal year 2013 is an $800 settlement with New York State, comprised of $430 of tax and $370 of interest. New York State had alleged that we were not permitted to file a single combined corporation franchise tax return with our subsidiaries. On January 18, 2011, the State had assessed a liability of $3,852, comprising $2,220 tax and $1,632 penalties and interest, for tax years ending April 30, 2004 through April 30, 2006. We had filed Petitions of Redetermination with the State of New York Division of Tax Appeals and had been scheduled for an administrative hearing on April 18-19, 2013. Tax years ending April 30, 2007 through April 30, 2009 were also being audited for the same tax matter. The settlement, which represented less than 8% of the potential cumulative liability for the years settled, was a monetary settlement without any change to our filing combined returns in New York and it closed tax years ending April 30, 2004 through April 30, 2010. Subsequent to the settlement of that audit, the State of New York began an audit of the tax years ended April 30, 2011 through April 30, 2013 and raised the same issue. We continued to believe that our position related to the filing of our State of New York tax returns was correct, and, based on the prior settlement and subsequent favorable litigation related to similar issues, we concluded at December 31, 2014 that no reserve would be required for our State of New York filings. During fiscal year 2015, we reached a settlement with the State of New York for the tax years ended April 30, 2011 through April 30, 2013 on a basis similar to the prior settlement to minimize out-of-pocket costs. Included in the current state tax provision for fiscal year 2015 is a $180 settlement paid to the State of New York for 2011-2013, which includes $168 tax and $12 interest. No audit has been initiated for tax years after 2013. Due to a change in law, we are permitted to and plan to elect to file a single combined corporation franchise tax return with our subsidiaries in New York beginning with 2015. We have not established any reserve under ASC 740 for the tax years ended April 30, 2014 and December 31, 2014, since we believed our position would more likely than not be successful.

The differences in the provision (benefit) for income taxes and the amounts determined by applying the Federal statutory rate to income before provision (benefit) for income taxes are as follows:

As of December 31, 2015 we have, for federal income tax purposes, net operating loss carryforwards of approximately $72,873 that expire in the fiscal years ending December 31, 2032 through 2033 and state net operating loss carryforwards of approximately $86,351 that expire in the fiscal years ending December 31, 2016 through 2035. The net operating loss carryforwards include approximately $383 for which a benefit will be recorded in additional paid-in capital when realized. In addition, we have $3,766 minimum tax credit carryforwards available that are not subject to a time limitation and $3,379 general business credit carryforwards which expire in the fiscal years ending December 31, 2023 through 2035. 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. 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 net increase in the valuation allowance was $5,886 for fiscal year 2015 and $2,581 for transition period 2014. For fiscal year 2013, the valuation allowance decreased by $5,084 due to the recognition of additional reversing temporary differences from the deferred tax liability recorded through goodwill related to the BBI acquisition. The $5,084 deferred tax liability related to the BBI acquisition resulted from temporary differences related to the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for income tax purposes.

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, the availability of tax planning strategies, 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. We believe we are able to support the deferred tax assets recognized as of the end of the year based on all of the available evidence. The net deferred tax liability as of December 31, 2015 includes deferred tax liabilities related to amortizable goodwill, which are anticipated to reverse in an indefinite future period and which are not currently available as a source of taxable income.

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, 2015			Eight Months Ended December 31, 2014			Fiscal Year Ended April 30, 2014
Unrecognized tax benefits at beginning of period	$	3,073		$	3,061		$	3,879
Gross increases for tax positions of prior years		168			14			22
Gross decreases for tax positions of prior years		(1	)		(1	)		(229	)
Reductions resulting from lapse of statute of limitations		(409	)		(1	)		(611	)
Gross increases resulting from reversal of benefit from lapse of statute of limitations		716			—			—
Settlements		(168	)		—			—
Unrecognized tax benefits at end of period	$	3,379		$	3,073		$	3,061

The gross increases for tax positions of prior years for fiscal year 2015 includes $168 tax from the settlement with New York State, which is offset by the ($168) settlements for fiscal year 2015. Included in the balances at December 31, 2015, December 31, 2014 and April 30, 2014 are $279, $0 and $0, 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 a decrease of $270 to unrecognized tax benefits 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 year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, we have accrued interest of $92, $143, $116 and $76 and penalties of $8, $8, $8 and $9, respectively. We accrued ($51), $26, $40 and $41 for interest and penalties in income tax expense related to uncertain tax positions during fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, 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 2015 remain open for examination, with limited exceptions.

Other Items and Charges

15. OTHER ITEMS AND CHARGES

Environmental Remediation Charge

In transition period 2014, we recorded an environmental remediation charge of $950 associated with remediation performed at Southbridge in the Eastern region. We had previously recorded an environmental remediation charge of $400 in fiscal year 2014 associated with remediating this site.

Expense from Divestiture, Acquisition and Financing Costs

In fiscal year 2014, we incurred $144 of expenses primarily associated with legal costs for the acquisition of the remaining 50% membership interest of Tompkins. See Note 3, Summary of Significant Accounting Policies for disclosure over the acquisition of Tompkins.

In fiscal year 2013, we incurred $1,410 of expenses including a $303 write-off of costs associated with the attempted refinancing of our Second Lien Notes, $602 of legal costs associated with the divestiture of Maine Energy Recovery Company, LP (“Maine Energy”) divestiture transaction, as discussed in Note 16, Divestiture Transactions and Discontinued Operations, and $505 of costs associated with the BBI acquisition.

Development Project Charge

In fiscal year 2014, we recorded a charge of $1,394 for deferred costs associated with a gas pipeline development project in Maine no longer deemed viable.

Severance and Reorganization Costs

In fiscal year 2014, we recorded a charge of $586 for severance costs associated with various planned reorganization efforts including the divestiture of Maine Energy.

In fiscal year 2013, we recorded a charge of $3,709 for severance costs associated primarily with the realignment of our operations in order to streamline functions and improve our cost structure, the closure of Maine Energy and a reorganization of senior management. Through the realignment of our operations we improved certain aspects of the sales function to better facilitate customer service and retention, pricing growth, and support of strategic growth initiatives; better aligned transportation, route management and maintenance functions at the local level; and reduced corporate overhead and staff to match organizational needs and reduce costs.

Discontinued Operations and Disposal Groups [Abstract]

Divestiture Transactions and Discontinued Operations

16. DIVESTITURE TRANSACTIONS AND DISCONTINUED OPERATIONS

We review planned business dispositions based on available information and events that have occurred to determine whether or not a business or disposal group qualifies for discontinued operations treatment. We analyze our operations that have been divested or classified as held-for-sale to determine if they qualify for discontinued operations accounting. A component of an entity, a group of components of an entity, or a business is required to be reported in discontinued operations once it meets the held for sale criteria, is disposed of by sale, or is disposed of other than by sale. A disposal is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. We evaluate whether the component has met the criteria to be classified as held-for-sale. To be classified as held-for-sale, the criteria established by FASB ASC 360-10 must be met as of the reporting date, including an active program to market the business and the disposition of the business within one year. A business that has not been disposed of may not be classified as discontinued operations until the held-for-sale criteria are met. No depreciation is recorded during the periods in which a disposal group is classified as held-for-sale.

Discontinued Operations

In fiscal year 2013, we initiated a plan to dispose of BioFuels and as a result, the assets associated with BioFuels were classified as held-for-sale and the results of operations were recorded as income from discontinued operations. Assets of the disposal group previously classified as held-for-sale, and subsequently included in discontinued operations, included certain inventory along with plant and equipment. In the first quarter of fiscal year 2014, we executed a purchase and sale agreement with ReEnergy Lewiston LLC (“ReEnergy”), pursuant to which we agreed to sell certain assets of BioFuels, which was located in our Eastern region, to ReEnergy. We agreed to sell the BioFuels assets for undiscounted purchase consideration of $2,000, which was to be paid to us in equal quarterly installments over five years commencing November 1, 2013, subject to the terms of the purchase and sale agreement. The related note receivable was paid in full by ReEnergy in transition period 2014. We recognized a $378 loss on disposal of discontinued operations in fiscal year 2014 associated with the disposition.

The operating results of these operations, including those related to prior years, have been reclassified from continuing to discontinued operations in the accompanying consolidated financial statements. Revenues and loss before income taxes attributable to discontinued operations are as follows:

	Fiscal Year Ended December 31,		Eight Months Ended December 31,		Fiscal Year Ended April 30,
	2015		2014		2014		2013
Revenues	$	—	$	—	$	3,316	$	12,033
Income (loss) before income taxes	$	—	$	—	$	284	$	(4,480	)

We allocate interest expense to discontinued operations. We have also eliminated inter-company activity associated with discontinued operations.

Divestiture Transactions

Sale of Business. In fiscal year 2015, we divested of a business, which included the sale of certain assets associated with various waste collection routes in the Western region, for total consideration of $872, resulting in a gain of $590.

Maine Energy. In fiscal year 2013, we executed a purchase and sale agreement with the City of Biddeford, Maine, pursuant to which we agreed to sell the real property of Maine Energy to the City of Biddeford. We agreed to sell Maine Energy for an undiscounted purchase consideration of $6,650, which was to be paid to us in installments over twenty-one years. The transaction closed in November 2012. In December 2012, we ceased operations of the Maine Energy facility and initiated the decommissioning, demolition and site remediation process in accordance with the provisions of the agreement. We have completed the demolition process and site remediation under the auspices and in accordance with work plans approved by the Maine Department of Environmental Protection and the U.S. Environmental Protection Agency. Based on the total incurred costs to fulfill our obligation under the agreement, we reversed a reserve of $1,149 of excess costs to complete the divestiture in fiscal year 2015. As of December 31, 2015, we had no remaining costs to complete the divestiture accrued as we had fulfilled our obligation under the agreement.

CARES and Related Transaction. CARES is a joint venture that owned and operated a water and leachate treatment facility for the natural gas drilling industry in Pennsylvania. Our joint venture partner in CARES is Altela, Inc. (“Altela”). We held an ownership interest in CARES of 51% and, in accordance with FASB ASC 810-10-15, we consolidated the assets, liabilities and results of operations of CARES into our consolidated financial statements due to our controlling financial interest in the joint venture. In fiscal year 2014, we determined that assets of the CARES water treatment facility were no longer operational or were not operating within product performance parameters. As a result, we initiated a plan to abandon and shut down the operations of CARES. It was determined that the carrying value of the assets of CARES was no longer recoverable and, as a result, the carrying value of the asset group was assessed for impairment and impaired in transition period 2014. As a result, we recorded an impairment charge of $7,455 transition period 2014 to the asset group of CARES in the Western region.

We executed a purchase and sale agreement in fiscal year 2015 pursuant to which we and Altela agreed to sell certain assets of the CARES water treatment facility to an unrelated third-party. We sold these assets of CARES for purchase consideration of $3,500, resulting in a gain of $2,850 in fiscal year 2015, 49% of which was attributable to Altela, the noncontrolling interest holder. As of December 31, 2015, we continued to pursue the dissolution of CARES in accordance with the CARES agreement.

In connection with this transaction, we also sold certain of our equipment and real estate to the same unrelated third-party for total consideration of $1,050, resulting in a gain of $928 in fiscal year 2015.

BioFuels. In transition period 2014, we recorded a $553 gain associated with the disposition of BioFuels in fiscal year 2014. As a part of the divestiture, we agreed to complete certain site improvements at BioFuels which were completed in December 2014. The gain recorded is the result of reversing the excess remaining reserves not needed to complete the site improvements.

18. RELATED PARTY TRANSACTIONS

Services

During fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, we retained the services of CCI, a company wholly owned by 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. Total purchased services charged to operations or capitalized to landfills for fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013 were $1,341, $5,562, $7,818 and $6,574, respectively, of which $28, $2 and $890 were outstanding and included in either accounts payable or other current liabilities as of December 31, 2015, December 31, 2014 and April 30, 2014, respectively.

In addition to the total purchased services, CCI contributed $350 in cash and $390 in non-compensable services for work performed at the Southbridge landfill to assist in the remediation of the site. See Note 15, Other Items and Charges for discussion over the Southbridge landfill environmental remediation.

Leases

In 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 April 2018 with a five year option to extend the terms. The terms of the lease agreements require monthly payments of approximately $27. Total expense charged to operations for fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013 under these agreements was $384, $263, $386 and $286, respectively.

Landfill Post-closure

We 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 year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, we paid $9, $8, $8, and $8, respectively, pursuant to this agreement. As of December 31, 2015, December 31, 2014 and April 30, 2014, we have accrued $75, $84 and $94, respectively, for costs associated with its post-closure obligations.

Employee Loan

In fiscal year 2014, we entered into an agreement with an employee to amend a promissory note, whereas the outstanding balance of $149, which had been included in Notes receivable – related party in the accompanying consolidated balance sheet, will be deemed paid in full in exchange for continued employment and the employee forgoing participation in the annual cash incentive plan and restricted stock program for a period of time specified in the amended note. Upon entering into the amended note, interest ceased accruing on the note and we recorded a charge of $149 in general and administration to reserve for the note.

19. SEGMENT REPORTING

We 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, the 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, major account and industrial services, discontinued operations, and earnings from equity method investees, as applicable, are included in our Other segment.

Our transfer and disposal revenues historically have been lower from the months of November through March. 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 newspaper advertising and retail activity during the holiday season.

Subsidiary Guarantors

21. SUBSIDIARY GUARANTORS

Our 2019 Notes are guaranteed jointly and severally, fully and unconditionally, by our significant wholly-owned subsidiaries. The Parent is the issuer and a non-guarantor of the 2019 Notes and the Parent has no independent assets or operations. The information which follows presents the condensed consolidating financial position, the consolidating results of operations and comprehensive income (loss) and the condensed consolidating statements of cash flows of (a) the Parent company only, (b) the combined guarantors (the “Guarantors”), each of which is 100% wholly-owned by the Parent, (c) the combined non-guarantors (the “Non-Guarantors”), (d) eliminating entries and (e) the consolidated total.

Accounting Changes (Policies)

12 Months Ended

Dec. 31, 2015

Accounting Changes and Error Corrections [Abstract]

New Accounting Policies Adopted and Pending Adoption

Adoption of New Accounting Pronouncements

Income Taxes

In November 2015, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update for the accounting for deferred income taxes. The update provides that deferred tax liabilities and assets be classified as noncurrent amounts in a classified statement of financial position. This guidance is effective prospectively or retrospectively for annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2016, with early adoption permitted. We adopted this guidance effective December 31, 2015 in order to simplify the presentation of deferred income taxes. This guidance impacts the balance sheet presentation of our deferred tax liabilities and assets. Prior periods were not retrospectively adjusted.

Discontinued Operations

In April 2014, the FASB issued an accounting standards update for the requirements of reporting discontinued operations. The update provides that an entity, a group of components of an entity, or a business is required to be reported in discontinued operations once it meets the held for sale criteria, is disposed of by sale, or is disposed of other than by sale only if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. The update also requires that additional disclosures about discontinued operations be made. This guidance is effective prospectively for annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2014. We adopted this guidance effective January 1, 2015 with no impact on our consolidated financial position or results of operations.

New Accounting Pronouncements Pending Adoption

Business Combinations

In September 2015, the FASB issued an accounting standards update for the accounting of measurement-period adjustments in business combinations. The update provides that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined as if the accounting had been completed at the acquisition date. This includes the acquirer presenting separately on the face of the income statement or disclosing in the notes thereto the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. This guidance is effective for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted. We expect that this guidance will have no impact on our consolidated financial position or results of operations upon adoption.

Debt Issuance Costs

In April 2015, the FASB issued an accounting standards update for the presentation of debt issuance costs. The update provides that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability. This guidance is effective on a retrospective basis for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted. This guidance will impact the balance sheet presentation of our debt issuance costs and related debt liabilities upon adoption.

Consolidation

In February 2015, the FASB issued an accounting standards update for the requirements of consolidation. The update provides changes to the analysis that an entity must perform to determine whether it should consolidate certain types of legal entities because in certain situations deconsolidated financial statements are necessary to better analyze the reporting entity’s economic and operational results. This guidance is effective for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We are currently assessing the potential impact this guidance may have on our consolidated financial statements as a result of adopting this standard.

Extraordinary and Unusual Items

In January 2015, the FASB issued an accounting standards update that eliminates the GAAP concept of extraordinary items. The update provides for the elimination of the requirements to consider whether an underlying event or transaction is extraordinary, but retains the presentation and disclosure guidance for items that are unusual in nature or occur infrequently and expands upon it to include items that are both unusual in nature and infrequently occurring. This guidance is effective prospectively or retrospectively for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We expect that this guidance will have no impact on our consolidated financial position or results of operations upon adoption.

Revenue Recognition

In May 2014, the FASB issued an accounting standards update for the recognition of revenue, which supersedes existing revenue recognition requirements and most industry-specific guidance. The update provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective for annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2017 under either full or modified retrospective adoption. Early application is permitted only as of annual reporting periods, and interim reporting periods within those reporting periods, beginning after December 15, 2016. We are currently assessing the potential impact this guidance may have on our consolidated financial statements as a result of adopting this standard.

Management's Estimates and Assumptions

Management’s Estimates and Assumptions

Preparation of our consolidated financial statements in accordance with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the accounting for and recognition and disclosure of assets, liabilities, equity, revenues and expenses. We must make these estimates and assumptions because certain information that we use is dependent on future events, cannot be calculated with a high degree of precision given the available data or simply cannot be readily calculated. In 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 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. In the opinion of management, these consolidated financial statements include all adjustments, which include normal recurring and nonrecurring adjustments, necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented. Actual results may differ materially from the estimates and assumptions that we use in the preparation of our consolidated financial statements.

Change in Fiscal Year

Change in Fiscal Year

In June 2014, we elected to change our fiscal year-end from April 30^th to December 31^st. This change in fiscal year became effective for our fiscal year beginning January 1, 2015 and ended December 31, 2015. As a result of this change, we filed a Transition Report on Form 10-KT for the eight-month transition period ended December 31, 2014. The references in these notes to the consolidated financial statements to the terms below reflect the respective reporting periods presented in the consolidated financial statements:

Term	Financial Reporting Period
fiscal year 2015	January 1, 2015 through December 31, 2015
transition period 2014	May 1, 2014 through December 31, 2014
fiscal year 2014	May 1, 2013 through April 30, 2014
fiscal year 2013	May 1, 2012 through April 30, 2013

Cash and Cash Equivalents

Cash and Cash Equivalents

We consider all highly liquid investments purchased with original maturities of three months or less to be cash equivalents.

Concentrations of Credit Risk

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents, restricted cash, accounts receivable-trade and derivative instruments. We maintain cash and cash equivalents and restricted cash 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-trade is limited because our customer base is comprised of a large number of geographically diverse customers, thus reducing the credit risk associated with any one customer group. As of December 31, 2015 no single customer or customer group represented greater than 5% of total accounts receivable-trade. We manage credit risk through credit evaluations, credit limits, monitoring procedures and, at times, credit insurance, but generally do not require collateral to support accounts receivable -trade. 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 - Trade, Net of Allowance for Doubtful Accounts

Accounts Receivable – Trade, Net of Allowance for Doubtful Accounts

Accounts receivable – trade represent receivables from customers for collection, transfer, recycling, disposal and other services. Our accounts receivable – trade 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 – trade, 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 trends, credit policy and a review of our accounts receivable – trade by aging category. Our reserve is evaluated and revised on a monthly basis. Past-due accounts receivable-trade are written off when deemed to be uncollectible. As of December 31, 2015, $44,707 of our accounts receivable – trade served as eligible collateral under our senior secured asset-based revolving credit and letter of credit facility (“ABL Facility”).

Inventory

Inventory

Inventory 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. As of December 31, 2015, $219 of our recyclables ready for sale served as eligible collateral under our ABL Facility.

Property, Plant and Equipment

Property, Plant and Equipment

Property, 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 Classification	Estimated Useful Life
Buildings and improvements		10-30 years
Machinery and equipment		5-10 years
Rolling stock		5-10 years
Containers		5-12 years
Furniture and Fixtures		3-8 years

The 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 disclosure over the amortization of landfill development costs and Note 6, Property, Plant and Equipment for disclosure over property, plant and equipment.

Landfill Accounting

Landfill Accounting

Life Cycle Accounting

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 our landfills, preparation costs include the total estimated costs to complete construction of the landfills’ permitted and expansion capacity.

Landfill Development Costs

We 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 fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013 was $62, $333, $256 and $368, respectively.

Landfill Airspace

We 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.

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 the measured density obtained from previous 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 the landfill 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 Costs

The 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.

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, lawyers, accounting personnel and consultants, 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 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 (2.0% as of December 31, 2015). 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, 2015 is between approximately 9.1% and 9.5%, 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 $3,370, $2,275, $3,967 and $3,538 in fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013, 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 8, Final Capping, Closure and Post-Closure Costs for disclosure over final capping, closure and post-closure costs asset retirement obligations.

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 cash. Surety bonds securing closure and post-closure obligations at December 31, 2015, December 31, 2014 and April 30, 2014 totaled $156,163, $144,633 and 133,847, respectively. Letters of credit securing closure and post-closure obligations as of December 31, 2015, December 31, 2014 and April 30, 2014 totaled $1,000, $1,104 and $1,104, respectively. See Note 5, Restricted Cash / Restricted Assets for disclosure over restricted cash securing closure and post-closure obligations.

Landfill Operating Lease Contracts

We entered into three landfill operation and management agreements in the fiscal year ended April 30, 2004 and one landfill operation and management agreement in the fiscal year ended April 30, 2006. 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 liabilities. 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 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. See Note 6, Property, Plant and Equipment for disclosure over depletion of landfill operating lease contracts.

Leases

Leases

We lease property and equipment in the ordinary course of our business. Our most significant lease obligations are for property and equipment specific to our industry. Our leases have varying terms. Some may include renewal or purchase options, escalation clauses, restrictions, lease concessions, capital project funding, penalties or other obligations that we consider in determining minimum rental payments. Leases are classified as either operating leases or capital leases, as appropriate.

Operating Leases. Many of our leases are operating leases. This classification generally can be attributed to either (i) relatively low fixed minimum rental payments or (2) minimum lease terms that are much shorter than the assets’ economic useful lives. We expect that, in the normal course of business, our operating leases will be replaced by other leases, or replaced with fixed asset expenditures. See Note 10, Commitments and Contingencies for disclosure over future minimum lease payments related to our operating leases.

Capital Leases. We capitalize assets acquired under capital leases at the inception of each lease and amortize them to depreciation expense over the lesser of the useful life of the asset or the lease term, as appropriate. The present value of the related lease payments is recorded as a debt obligation. See Note 9, Long-Term Debt and Capital Leases for disclosure over our future maturities of debt, which includes capital lease payments.

Goodwill and Intangible Assets

Goodwill and Intangible Assets

Goodwill. 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 7, 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 7, Goodwill and Intangible Assets for disclosure over intangible assets.

Investments in Unconsolidated Entities

Investments in Unconsolidated Entities

Investments 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, 2015, December 31, 2014 and April 30, 2014, we had no investments accounted for under the equity 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. Additionally, 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. See “Asset Impairments” accounting policy below and Note 12, Fair Value of Financial Instruments for further disclosure over our investments.

Equity Method Investments

GreenFiber. In the fiscal year ended April 30, 2001, we entered into a joint venture agreement with Louisiana-Pacific Corporation (“LP”) to combine our respective cellulose insulation businesses into a single operating entity, US GreenFiber LLC (“GreenFiber”). In fiscal year 2014, we and LP executed a purchase and sale agreement with a limited liability company formed by Tenex Capital Partners, L.P., pursuant to which we and LP agreed to sell our membership interests in GreenFiber for total cash consideration of $18,000 plus an expected working capital true up less any indebtedness and other unpaid transaction costs of GreenFiber as of the closing date. The transaction was completed in fiscal year 2014 for $19,194 in gross cash proceeds, including a $1,194 working capital adjustment. After netting indebtedness of GreenFiber and transaction costs, our portion of the net cash proceeds based on our 50% membership interest amounted to $3,442. After considering the $593 impact of our unrealized losses relating to derivative instruments in accumulated other comprehensive loss on our investment in GreenFiber, we recorded a gain on sale of equity method investment of $593 in fiscal year 2014. We had previously accounted for our 50% membership interest in GreenFiber using the equity method of accounting.

Tompkins. In the fiscal year ended April 30, 2012, we finalized the terms of a joint venture agreement with FCR, LLC (“FCR”) to form Tompkins County Recycling LLC (“Tompkins”), a joint venture that operates a material recovery facility (“MRF”) located in Tompkins County, New York and processes and sells commodities delivered to the Tompkins MRF. In fiscal year 2014, we purchased the remaining 50% membership interest of Tompkins for total cash consideration of $425. The acquisition-date fair value of our investment in Tompkins, which was determined using the cost approach based on an assessment of the price to purchase the acquired assets of Tompkins, prior to the acquisition date was $300. We recognized a $106 gain through loss from equity method investments due to the remeasurement in fiscal year 2014. As a result of the purchase, we no longer account for our investment in Tompkins using the equity method of accounting and began including the results of Tompkins in our consolidated financial statements.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

Our financial instruments include cash and cash equivalents, accounts receivable-trade, restricted cash and investments held in trust on deposit with various banks as collateral for our obligations relative to our landfill final capping, closure and post-closure costs and 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 9, Long-Term Debt and Capital Leases and Note 12, 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 Combinations

Business Combinations

We 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 4, Business Combinations for disclosure over business acquisitions.

Environmental Remediation Liabilities

Environmental Remediation Liabilities

We 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 10, Commitments and Contingencies for disclosure over environmental remediation liabilities.

Self-Insurance Liabilities and Related Costs

Self-Insurance Liabilities and Related Costs

We are self-insured for vehicles and workers’ compensation with reinsurance coverage limiting our maximum exposure. Our maximum exposure in fiscal year 2015 under the workers’ compensation plan is $1,000 per individual event. Our maximum exposure in fiscal year 2015 under the automobile plan is $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 actuarially determined liability is calculated based on historical data, which considers both the frequency and settlement amount of claims. Our self-insurance reserves totaled $11,560, $10,863 and $10,280 as of December 31, 2015, December 31, 2014 and April 30, 2014, 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 Taxes

Income Taxes

We 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. See Note 14, Income Taxes for disclosure related to income taxes.

Derivatives and Hedging

Derivatives and Hedging

We 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 also 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 effective cash flow hedges, the change in the fair value of these derivatives is recorded in our stockholders’ equity (deficit) as a component of accumulated other comprehensive income (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 are 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, 2015.

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 effective cash flow hedges, the change in fair value is recorded in our stockholders’ equity (deficit) as a component of accumulated other comprehensive income (loss) and included in interest expense at the same time as interest expense is affected by the hedged transaction. Differences paid or received over the life of the agreements are recorded as additions to or reductions of interest expense on the underlying debt. We were not party to any interest rate derivative agreements deemed to be effective cash flow hedges as of December 31, 2015.

For interest rate derivatives deemed to be ineffective cash flow hedges, the change in fair value is recorded through earnings and included in loss (gain) on derivative instruments. We are currently party to one interest rate swap deemed to be an ineffective cash flow hedge that is scheduled to mature on March 15, 2016 and were party to another interest rate swap deemed to be an ineffective cash flow hedge that was settled in fiscal year 2015 for $830 in conjunction with the refinancing of our senior revolving credit and letter of credit facility that was due March 18, 2016 (“Senior Credit Facility”). See Note 12, Fair Value of Financial Instruments for fair value disclosure over derivative instruments.

Contingent Liabilities

Contingent Liabilities

We 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 10, Commitments and Contingencies for disclosure over loss contingencies. 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 4, Business Combinations for disclosure over a contingent liability assumed as part of the acquisition of a business.

Revenue Recognition

Revenue Recognition

We recognize collection, transfer, recycling and disposal revenues as the services are provided. Certain customers are billed in advance and, accordingly, recognition of the related revenues is deferred until the services are provided.

Revenues from the sale of recycled materials are recognized upon shipment. Rebates to certain municipalities based on sales of recyclable materials are recorded upon the sale of such recyclables to third-parties and are included as a reduction of revenues. Revenues for processing of recyclable materials are recognized when the related service is provided. Revenues from the brokerage of recycled materials are recognized on a net basis at the time of shipment.

Asset Impairments

Asset Impairments

Recovery 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, and identifiable intangible 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 15, Other Items and Charges for disclosure related to long-lived asset impairments recognized during the reporting periods.

Goodwill. We annually assess goodwill impairment at the end of our fiscal year or more frequently if events or circumstances indicate that impairment may exist. Historically, we have performed our annual goodwill impairment test using our fiscal year-end, or April 30^th, as the measurement date. Effective with the change in our fiscal year-end from April 30^th to December 31^st, we have voluntarily changed our goodwill impairment measurement date from April 30^th to December 31^st to coincide with the change in our fiscal year-end. The voluntary change in our goodwill impairment measurement date was applied prospectively as it represents the modification of an existing principle based on new facts and circumstances.

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 capitalization.

If the fair value of the 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 in fiscal year 2015. As of December 31, 2015, the Step 1 testing for goodwill impairment performed for the 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 the Eastern, Western, Recycling and Customer Solutions reporting units exceeded its carrying value by in excess of 22.9%. We incurred no impairment of goodwill as a result of our annual goodwill impairment tests in fiscal year 2015, transition period 2014, fiscal year 2014 and fiscal year 2013. However, there can be no assurance that goodwill will not be impaired at any time in the future.

Cost Method Investments. As of December 31, 2015, we owned 5.3% of the outstanding common stock of Recycle Rewards, Inc. (“Recycle Rewards”), a company that markets an incentive based recycling service. In both fiscal year 2015 and transition period 2014, 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 2015, and had a valuation analysis performed by a third-party valuation specialist in transition period 2014, both of 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 these analyses, it was determined in each case that the fair value of our cost method investment in Recycle Rewards was less than the carrying amount and, therefore, we recorded other-than-temporary investment impairment charges of $1,090 and $2,320 in fiscal year 2015 and transition period 2014, respectively. As of December 31, 2015, the carrying amount of our cost method investment in Recycle Rewards was $1,070.

As of December 31, 2015, we owned 9.8% of the outstanding equity value of GreenerU, Inc. (“GreenerU”), a services company focused on providing energy efficiency, sustainability and renewable energy solutions to colleges and universities. In fiscal year 2015, it was determined based on the operating performance and recent indications of third-party interest in GreenerU that our cost method investment in GreenerU was potentially impaired. A valuation analysis was performed by a third-party valuation specialist using a market approach based on an option pricing methodology to determine an equity value and fair market value per share for GreenerU. Based on this analysis, it was determined that the fair value of our cost method investment in GreenerU was less than the carrying amount and, therefore, we recorded an other-than-temporary investment impairment charge of $691 in fiscal year 2015. As of December 31, 2015, the carrying amount of our cost method investment in GreenerU was $309.

As of December 31, 2015, we owned 17.0% and 16.2% of the outstanding common stock of AGreen Energy LLC (“AGreen”) and BGreen Energy LLC (“BGreen”), respectively. In fiscal year 2015, AGreen and BGreen, both of which we account for as cost method investments, entered into agreements that resulted in the contribution and sale of certain assets and liabilities of AGreen and BGreen to a limited liability company in exchange for partial ownership interests in a parent of that limited liability company. As a result of the transactions, we performed an analysis to determine whether an other-than-temporary impairment in the carrying value of our cost method investments had occurred. Based on the analysis performed, which measured the fair value of our cost method investments using an in-exchange valuation premise under the market approach that utilized the estimated purchase consideration received, we recorded an investment impairment charge of $318 in fiscal year 2015. As of December 31, 2015, the carrying amount of our cost method investment in AGreen and BGreen was $297.

Stock-Based Compensation

Stock-Based Compensation

All 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. Stock-based compensation expense is based on the number of awards ultimately expected to vest and is therefore reduced for an estimate of the awards that are expected to be forfeited prior to vesting.

The fair value of each stock option 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 option holders will retain their vested stock options before exercising them and the estimated volatility of our common stock price over the expected term.

See Note 11, Stockholders Deficit for disclosure over stock-based compensation.

Earnings per Share

Earnings per Share

Basic earnings per share is computed by dividing the net loss from continuing operations attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated based on the combined weighted average number of common shares and potentially dilutive shares, which include, where appropriate, the assumed exercise of employee stock options, unvested restricted stock awards, unvested restricted stock units and unvested performance stock units. In computing diluted earnings per share, we utilize the treasury stock method. See Note 17, Earnings Per Share for disclosure over the calculation of earnings per share.

Discontinued Operations

Discontinued Operations

We analyze our operations that have been divested or classified as held-for-sale to determine if they qualify for discontinued operations accounting. A component of an entity, a group of components of an entity, or a business is required to be reported in discontinued operations once it meets the held for sale criteria, is disposed of by sale, or is disposed of other than by sale. A disposal is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. See Note 16, Divestiture Transactions and Discontinued Operations for disclosure over discontinued operations.
