CASELLA WASTE SYSTEMS, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
(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 unaudited 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. Our significant accounting policies are more fully discussed in Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, which was filed with the SEC on March 2, 2016.
Preparation of our consolidated financial statements in accordance with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the accounting for and recognition and disclosure of assets, liabilities, equity, revenues and expenses. We must make these estimates and assumptions because certain information that we use is dependent on future events, cannot be calculated with a high degree of precision given the available data, or simply cannot be readily calculated. In the opinion of management, these consolidated financial statements include all adjustments, which include normal recurring and nonrecurring adjustments, necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented. The results for the three and six months ended June 30, 2016 may not be indicative of the results for any other interim period or the entire fiscal year. The consolidated financial statements presented herein should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015.
For comparative purposes, certain prior period amounts in the consolidated financial statements, including the presentation of debt issuance costs, have been reclassified to conform to the current period presentation. See Note 2,  Accounting Changes  for discussion regarding changes to the presentation of debt issuance costs and Note 6,  Long-Term Debt  for the updated disclosure.
Subsequent Events
We have evaluated subsequent events or transactions that have occurred after the consolidated balance sheet date of June 30, 2016, but prior to the filing of the consolidated financial statements with the SEC on this Quarterly Report on Form 10-Q. We have determined that there are no subsequent events that require disclosure in this Quarterly Report on Form 10-Q.

2.	ACCOUNTING CHANGES	
A table providing a brief description of recent Accounting Standards Updates (“ASU”) to the Accounting Standards Codification (“ASC”) issued by the Financial Accounting Standards Board (“FASB”) deemed to have a material effect on our consolidated financial statements upon adoption follows:

Standard	  	Description	  	Effect on the Financial Statements or Other
Significant Matters	
Accounting standards that were adopted effective January 1, 2016	
ASU 2016-09: Compensation - Stock Compensation (Topic 718)	  	Several aspects of the accounting for share-based payment award transactions are simplified, including: (a) income tax consequences; (b) classification of awards as either equity or liabilities; and (c) classification on the statement of cash flows.	  	The adoption of this ASU resulted in the following: (1) our stock-based compensation accounting policy was updated to record stock-based compensation expense for all equity-based awards by accounting for forfeitures as they occur; (2) our accounting for excess tax benefits and tax deficiencies in the calculation of income tax expense was updated; and (3) excess tax benefits are classified as a cash flow from operating activities and are no longer separated from income tax cash flows and classified as a cash flow from financing activities.	
 	 	 	
ASU 2015-03 and 15: Imputation of Interest (Topic 835-30)	  	These amendments require 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 that debt liability, consistent with debt discounts.	  	The adoption of this ASU resulted in the presentation of debt issuance costs on our balance sheet being treated as a direct reduction of the carrying amount of the debt liability rather than a capitalized other non-current asset. See Note 6,  Long-Term Debt  for the updated disclosure.

A table providing a brief description of recent accounting pronouncements that may have a material effect on our consolidated financial statements upon adoption follows:

Standard	  	Description	  	Effect on the Financial Statements or Other
Significant Matters	
Accounting standards that are not yet adopted	
ASU 2016-02: Leases (Topic 842)	  	Requires that a lessee recognize at the commencement date: a lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term.	  	The adoption of this ASU primarily impacts the balance sheet through the recognition of a right-of-use asset and lease liability for all leases. This guidance is effective January 1, 2019 using a modified retrospective transition approach with early adoption permitted.	
 	 	 	
ASU 2016-01: Financial Instruments - Overall (Topic 825-10)	  	Requires the following: (1) equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (2) entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (3) separate presentation of financial assets and financial liabilities by measurement category and form of financial asset; and (4) the elimination of the disclosure requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost.	  	The adoption of this ASU results in a cumulative-effect adjustment to the balance sheet, the recognition of changes in fair value of certain equity investments in net income, and enhanced dislosure. This guidance is effective January 1, 2018 with a cumulative-effect adjustment.	
 	 	 	
ASU 2014-09, ASU 2015-14, ASU 2016-10 and ASU 2016-12: Revenue from Contracts with Customers (Topic 606)	  	The core principle of the guidance is 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.	  	We are currently evaluating the alternative methods of adoption and the effect on our consolidated financial statements and related disclosures. This guidance is effective January 1, 2018 using a full or modified retrospective approach with early adoption permitted January 1, 2017.

5.	ACCRUED FINAL CAPPING, CLOSURE AND POST CLOSURE	
Accrued final capping, closure and post-closure costs include the current and non-current portion of costs associated with obligations for final capping, closure and post-closure of our landfills. We estimate our future final capping, closure and post-closure costs in order to determine the final capping, closure and post-closure expense per ton of waste placed into each landfill. The anticipated 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.

Financing Activities
New York Bonds 2016
In the three months ended June 30, 2016, we completed a financing transaction involving the issuance by the New York State Environmental Facilities Corporation of $15,000 aggregate principal amount of Solid Waste Disposal Revenue Bonds Series 2014R-2 (“New York Bonds 2016”). We borrowed the proceeds of the offering of the New York Bonds 2016 to finance or refinance certain capital projects in the state of New York, and to pay certain costs of issuance of the New York Bonds 2016. As of June 30, 2016, we had $848 of restricted cash reserved for repayment of certain capital projects in the state of New York as a result of this financing.
As of June 30, 2016, we had outstanding $15,000 aggregate principal amount of New York Bonds 2016. The New York Bonds 2016, which are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 3.125% per annum through May 31, 2026, at which time they may be converted from a fixed rate to a variable rate, and interest is payable on June 1 and December 1 of each year.
Loss on Debt Extinguishment
Senior Subordinated Notes
In the three months ended June 30, 2016, we redeemed and permanently retired $12,500 aggregate principal amount of 7.75% senior subordinated notes due February 2019 (“2019 Notes”) at a redemption price equal to 101.938% of the principal amount thereof plus accrued and unpaid interest thereon in order to maximize interest savings by paying down our most expensive debt. As a result of the redemption, we recorded a loss on debt extinguishment of $525 in the three months ended June 30, 2016 related to the premium associated with the redemption price, the write off of debt issuance costs and unamortized original issue discount in proportion with the settlement amount.
In the three months ended June 30, 2016, we repurchased and permanently retired $3,000 aggregate principal amount of 2019 Notes at a repurchase price of $102.25 in order to maximize interest savings by paying down our most expensive debt. As a result of the repurchase, we recorded a loss on debt extinguishment of $68 in the three months ended June 30, 2016 related to the premium associated with the repurchase price, the write off of debt issuance costs and unamortized original issue discount in proportion with the settlement amount.
In the quarter ended March 31, 2016, we repurchased and permanently retired $4,230 aggregate principal amount of 2019 Notes at a repurchase price of $96.75 in order to maximize interest savings by paying down our most expensive debt. As a result of the repurchase, we recorded a gain on debt extinguishment of $48 in the quarter ended March 31, 2016 related to the non-cash gain associated with the below par repurchase price, net of the write off of debt issuance costs and unamortized original issue discount in proportion with the settlement amount.
Senior Credit Facility
In the quarter ended March 31, 2015, we recorded a charge of $521 as a loss on debt extinguishment related to the write-off of debt issuance costs in connection with changes to the borrowing capacity from our previous senior revolving credit and letter of credit facility that was due March 2016 (“Senior Credit Facility”) to our current senior secured asset-based revolving credit and letter of credit facility due February 2020 (“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.
 
7.	COMMITMENTS AND CONTINGENCIES	
Legal Proceedings
In the ordinary course of our business and as a result of the extensive governmental regulation of the solid waste industry, we are subject to various judicial and administrative proceedings involving state and local agencies. In these proceedings, an agency may seek to impose fines or to revoke or deny renewal of an operating permit held by us. From time to time, we may also be subject to actions brought by special interest or other groups, adjacent landowners or residents in connection with the permitting and licensing of landfills and transfer stations, or allegations of environmental damage or violations of the permits and licenses pursuant to which we operate. In addition, we may be named defendants in various claims and suits pending for alleged damages to persons and property, alleged violations of certain laws and alleged liabilities arising out of matters occurring during the ordinary operation of a waste management business.
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
 
13

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 (“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 (“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 alleged that we had the obligation to provide a specialized type of wood fuel to the Facility or, alternatively, that we owed a “Fuel Replacement Fee” of up to $2,000 a year (subject to the possibility of certain credits against such payments). The Contract was to expire in 2036.
On or about February 10, 2016, we reached an agreement in principle with MFGR to dismiss the Lawsuit with prejudice, and to resolve all outstanding claims of any nature including future claims which could arise under the Contract, and a Joint Stipulation of Dismissal with Prejudice was filed with the Superior Court on April 15, 2016. On or about April 12, 2016, the Parties entered into a Settlement Agreement (“SA”) along with other ancillary agreements. Pursuant to the SA, we paid MFGR $1,250 upon execution of the SA, and will pay $350 a year for five years following execution of the SA. Accordingly, taking into account the net present value of the settlement payments, we recorded a reserve of $2,616 that included a contract settlement charge of $1,940 and operating expenses of $676 recorded in the fiscal year ended December 31, 2015. As of June 30, 2016, $1,355 of this reserve remains outstanding. We have also reserved $34 for legal costs associated with the Lawsuit and SA as of June 30, 2016.
We have also entered 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 Landfill”), and MFGR has entered into a waste disposal agreement at market prices with us for the disposal at Juniper Ridge Landfill of waste materials produced in the demolition or re-purposing of the Facility.
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 matters represents our potential or outstanding material claims.
Southbridge Recycling & Disposal Park, Inc.
In October 2015, our Southbridge Recycling and Disposal Park, Inc. (“SRD”) subsidiary reported to the Massachusetts Department of Environmental Protection (“MADEP”) results of analysis of samples collected pursuant to our existing permit from private drinking water wells located near the Town of Southbridge, Massachusetts Landfill (“Southbridge Landfill”), which is operated by SRD. Those results indicated the presence of contaminants above the levels triggering notice and response obligations under MADEP regulations. In response to those results, we are carrying out an Immediate Response Action pursuant to state law. Further, we have implemented a plan to analyze and better understand the groundwater near the Southbridge Landfill and we are investigating with the objective of identifying the source or sources of the elevated levels of contamination measured in the well samples. If it is determined that some or all of the contamination originated at the Southbridge Landfill, we will work with the Town of Southbridge (“Town”), the Southbridge Landfill owner and operator of an unlined portion of the Southbridge Landfill prior to our operation of a double-lined portion of the Southbridge Landfill
 
14

commencing in 2004, to evaluate and allocate the liabilities related to that contamination. In July 2016, we sent correspondence to the Town pursuant to Chapter 21E of Massachusetts General Laws advising the Town that we have incurred expenditures of $1,548, that we expect the Town to reimburse us for such costs, and for the Town to be responsible for any such costs in the future, as well as any other costs or liabilities resulting from the release of contaminants from the Southbridge Landfill.
In February 2016, we received a Notice of Intent to Sue under the Resource Conservation and Recovery Act from a law firm representing residents from approximately 40 homes located in the vicinity of the Southbridge Landfill, indicating its intent to file suit against us. We believe it is reasonably possible that a loss may occur as a result of this potential matter although an estimate of loss cannot be reasonably provided at this time. We would also expect the Town to be responsible for any costs or liabilities associated with this suit relative to alleged contamination originating from the Southbridge Landfill pursuant to Chapter 21E.
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%. A summary of the changes to the environmental remediation liability associated with the Potsdam environmental remediation liability follows:

8.	STOCKHOLDERS’ EQUITY	
Stock Based Compensation
Shares Available For Issuance
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
 
15

other similar events), plus (ii) such additional number of shares of Class A common stock as were subject to stock options granted under our 1993 Incentive Stock Option Plan, 1994 Non-statutory Stock Option Plan, 1996 Stock Option Plan, and 1997 Stock Incentive 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 June 30, 2016, there were 562 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 awards may be granted under the 2006 Plan after October 9, 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
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.

As of June 30, 2016, total unrecognized stock-based compensation expense related to outstanding stock options was $929, which will be recognized over a weighted average period of 1.8 years.
Other Stock Awards
We grant restricted stock awards, restricted stock units and performance-based 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-based stock units vest at a future date following the grant date and are based on the attainment of certain performance targets.

10.	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
Our financial instruments for the periods reported below 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 restricted cash, which are valued using quoted market prices, are included as restricted assets in the Level 1 tier below. The fair value of the interest rate derivative, included in the Level 2 tier below, was calculated based on a valuation obtained from our counter-party based primarily on the three month London Interbank Offered Rate yield curve that was observable at commonly quoted intervals for the full term of the swap. The interest rate derivative matured on March 15, 2016. We recognize all derivatives accounted for on the balance sheet at fair value.

Fair Value of Debt
As of June 30, 2016, the fair value of our fixed rate debt, including our 2019 Notes, Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-2 (“FAME Bonds 2005R-2”), Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2015 (“FAME Bonds 2015”), Vermont Economic Development Authority Solid Waste Disposal Long-Term Revenue Bonds Series 2013 (“Vermont Bonds”), New York State Environmental Facilities Corporation Solid Waste Disposal Revenue Bonds Series 2014 (“New York Bonds 2014”), New York Bonds 2016 and Solid Waste Disposal Revenue Bonds Series 2013 issued by the Business Finance Authority of the State of New Hampshire (“New Hampshire Bonds”) was approximately $466,317 and the carrying value was $453,970. 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 2014, the New York Bonds 2016 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 2014, the New York Bonds 2016 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 June 30, 2016, the fair value of our ABL Facility is considered to be Level 2 within the fair value hierarchy as the fair value approximates its carrying value of $55,800 based on current borrowing rates for similar types of borrowing arrangements. The carrying value of our remaining material variable rate debt, the Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 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.

11.	DIVESTITURE TRANSACTIONS	
Sale of Business
In the three months ended June 30, 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 $677 in the three months ended June 30, 2015.
Maine Energy
In the fiscal year ended April 30, 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 Recovery Company, LP (“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. In consideration of the fact that the project was substantially completed and based on incurred costs to date and estimates at that time regarding the remaining costs to fulfill our obligation under the purchase and sale agreement, we reversed a reserve of $1,157 of excess costs to complete the divestiture in the quarter ended March 31, 2015. As of June 30, 2016, we had no remaining costs to complete the divestiture accrued as we had fulfilled our obligation under the agreement.
CARES and Related Transaction
Casella-Altela Regional Environmental Services, LLC (“CARES”) was 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 was Altela, Inc. (“Altela”). Our ownership interest in CARES was 51%. In accordance with FASB ASC 810-10-15, we consolidate the assets, liabilities and results of operations of CARES and its wholly owned subsidiary, CARES McKean, LLC, into our consolidated financial statements due to our controlling financial interest in the joint venture.
On February 9, 2015, we executed a purchase and sale agreement 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 the quarter ended March 31, 2015, 49% of which was attributable to Altela, the noncontrolling interest holder. In connection with this transaction, we also sold certain of our equipment and real estate to the same buyer for total consideration of $1,050, resulting in a gain of $928 in the quarter ended March 31, 2015.
In the three months ended June 30, 2016, we dissolved CARES in accordance with the CARES Limited Liability Company Agreement. We are in the process of dissolving CARES McKean, LLC in accordance with Pennsylvania dissolution proceedings and upon dissolution we will deconsolidate the assets, liabilities and equity components, including the noncontrolling interest.
 
12.	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.

Company 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, 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, major account and industrial services, discontinued operations, and earnings from equity method investees are included in our Other segment, as applicable.
As of July 15, 2016, we owned and/or operated 34 solid waste collection operations, 46 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.
Results of Operations
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. Revenues from organics services, ancillary operations, and major account and industrial services are included in our Other segment. Our revenues are shown net of inter-company eliminations.
A summary of revenues attributable to service provided (dollars in millions and as a percentage of total revenues) follows:

Solid waste revenues
Price.
 
•	 	The price change component in quarterly solid waste revenues decline is the result of $2.9 million from favorable collection pricing, including a floating sustainability recycling adjustment fee to mitigate recycling commodity risk, and $0.8 million from favorable disposal pricing associated with our landfills and transfer stations.	
 
•	 	The price change component in year-to-date solid waste revenues growth is the result of $6.5 million from favorable collection pricing, including a floating sustainability recycling adjustment fee to mitigate recycling commodity risk, and $1.2 million from favorable disposal pricing associated with our landfills and transfer stations.	
Volume.
 
•	 	The volume change component in quarterly solid waste revenues decline is the result of $6.3 million from disposal volume decreases (of which $3.3 million relates to lower landfill volumes, including lower drill cutting volumes at our McKean landfill and the diversion of certain lower priced tons, $2.4 million relates to lower transportation volumes associated with lower drill cutting volumes, and $0.6 million relates to lower transfer station volumes), partially offset by $0.3 million from higher collection volumes. The volume decline in quarterly solid waste revenues growth is the result of winter weather fluctuations year-over-year, which resulted in volume shifts between quarters.	
 
•	 	The volume change component in year-to-date solid waste revenues growth is the result of $2.2 million from disposal volume decreases (of which $2.1 million relates to lower transportation volumes associated with lower drill cutting volumes, $0.9 million relates to lower landfill volumes, and $0.8 million relates to higher transfer station volumes) and $0.1 million from lower processing volumes, partially offset by $1.5 million from higher collection volumes.	
Commodity price and volume.
 
•	 	The commodity price and volume change component in quarterly solid waste revenues decline is primarily the result of $0.2 million from unfavorable energy pricing at our landfill gas-to-energy operations, offset by $0.2 million from higher landfill gas-to-energy volumes and favorable commodity pricing.	
 
•	 	The commodity price and volume change component in year-to-date solid waste revenues growth is primarily the result of $0.7 million from unfavorable energy pricing at our landfill gas-to-energy operations, partially offset by $0.3 million from higher landfill gas-to-energy volumes.	
Acquisitions and divestitures.
 
•	 	The acquisitions and divestitures change component in quarterly and year-to-date solid waste revenues change is the result of the acquisition of three transfer stations in the three months ended June 30, 2016, partially offset by the divestiture of a business in May 2015.	
Organics revenues
 
•	 	Quarterly and year-to-date revenues increased as the result of higher volumes in the three months ended June 30, 2016.	
Customer Solutions revenues
 
•	 	Quarterly revenues decreased slightly as the result of lower volumes, which offset slightly higher volumes in the quarter ended March 31, 2016 leaving year-to-date revenues flat.	
 
25

Recycling revenues
 
•	 	Quarterly revenues increased from higher commodity pricing in the marketplace combined with higher commodity volumes and higher tipping fees.	
 
•	 	Year-to-date revenues increased from favorable commodity pricing in the marketplace in the three months ended June 30, 2016, as compared to unfavorable commodity pricing in the quarter ended March 31, 2016, combined with higher commodity volumes and higher tipping fees.	
Operating Expenses
A summary of cost of operations, general and administration expense, and depreciation and amortization expense (dollars in millions and as a percentage of total revenues) follows:

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, and 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.
The period-to-period changes in cost of operations can be primarily attributed to the following:
 
•	 	Third-party direct costs decreased $2.5 million quarterly and $2.7 million year-to-date due to: lower disposal and hauling costs associated with decreased volumes in our Western region; lower purchased material costs in our Customer Solutions business; lower disposal costs in our Organics business in the quarter ended March 31, 2016; and lower purchased material costs in our Recycling business. These costs were partially offset by higher hauling and transportation costs in our Organics and Customer Solutions businesses.	
 
•	 	Fuel costs decreased $0.8 million quarterly and $1.7 million year-to-date due to lower diesel fuel prices in the marketplace along with the consumption of less diesel fuel in our fleet.	
 
•	 	Labor and related benefit costs decreased $0.9 million quarterly and $0.4 million year-to-date due to lower healthcare costs on a quarterly basis related to plan improvements and lower overall claim activity, and lower labor and related benefit costs on lower volumes in the Western region. This was partially offset by additional labor and related benefit costs on higher volumes in our Eastern region.	
 
•	 	Direct operational costs remained flat quarterly and increased $2.2 million year-to-date due to: higher equipment rental costs; higher vehicle self-insurance costs; higher gas control and other landfill operating costs in our Eastern region; and higher host royalty fees on a year-to-date basis. Increased quarterly direct operational costs were offset by lower leachate disposal costs at certain landfills in our Western region; lower landfill operating lease amortization on lower rates and tons at our Southbridge landfill in our Eastern region; and lower host royalty fees at our Southbridge landfill in the Eastern region.	
 
•	 	Maintenance and repair costs increased $0.8 million quarterly and $1.7 million year-to-date primarily due to higher maintenance costs in our Recycling segment and higher facility maintenance costs. This was partially offset by lower quarterly fleet maintenance costs, which resulted in a decrease in our fleet maintenance costs year-to-date.	
 
26

General and Administration
General and administration expense includes management, clerical and administrative compensation, bad debt expense, as well as overhead costs, professional service fees and costs associated with marketing, sales force and community relations efforts.
The period-to-period changes in general and administration expenses can be primarily attributed to the following:
 
•	 	Labor and related benefit costs increased $0.2 million quarterly and $1.4 million year-to-date primarily due to higher estimated incentive compensation.	
 
•	 	Bad debt expense increased $0.3 million quarterly and remained flat year-to-date due to collectability issues associated with a disposal customer.	
 
•	 	Professional fees decreased $0.5 million quarterly and remained flat year-to-date primarily due to timing as lower legal, accounting and audit fees in the three months ended June 30, 2016 offset higher fees in the quarter ended March 31, 2016.	
Depreciation and Amortization
Depreciation and amortization expense includes: (i) depreciation of property and equipment, including assets recorded for capital leases, on a straight-line basis over the estimated useful lives of the assets; (ii) amortization of landfill costs (including those costs incurred and all estimated future costs for landfill development and construction, along with asset retirement costs arising from closure and post-closure obligations) on a units-of-consumption method as landfill airspace is consumed over the total estimated remaining capacity of a site, which includes both permitted capacity and unpermitted expansion capacity that meets 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.
A summary of the components of depreciation and amortization expense (dollars in millions and as a percentage of total revenues) follows:

The period-to-period changes in depreciation and amortization expense can be primarily attributed to the following:
 
•	 	Quarterly landfill amortization expense decreased due to lower landfill volumes, partially offsetting an overall increase in our average amortization rate and higher landfill volumes in the quarter ended March 31, 2016.	
 
•	 	Quarterly and year-to-date other amortization expense decreased due to the makeup and timing of definite life intangible assets.	
Divestiture Transactions
Sale of Business. In the three months ended June 30, 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 $0.9 million, resulting in a gain of $0.7 million in the three months ended June 30, 2015.
 
27

Maine Energy. In the quarter ended March 31, 2015, we recorded a gain of $4.9 million associated with the divestiture of Maine Energy Recovery Company, LP (“Maine Energy”) and the sale of certain assets of the Casella-Altela Regional Environmental Services, LLC (“CARES”) water treatment facility, along with certain other equipment and real estate of ours, to a third-party. See Note 11,  Divestiture Transactions  to our consolidated financial statements included under Item 1 of this Quarterly Report on Form 10-Q for further disclosure.
Other Expenses
Interest Expense, net
Our interest expense, net decreased $0.1 million quarterly and $0.2 million year-to-date primarily due to lower average debt balances and changes to our capitalization structure. Specifically, in order to reduce costs and our exposure to financing and interest rate risk, we repurchased or redeemed, as applicable, and retired $34.4 million of our most expensive debt, the 7.75% senior subordinated notes due February 2019 (“2019 Notes”), since September 2015; we completed the issuance of $15.0 million of Solid Waste Disposal Revenue Bonds Series 2014R-2 (“New York Bonds 2016”) in June 2016; we completed the issuance of $15.0 million of Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2015 (“FAME Bonds 2015”) in August 2015; and we completed the refinancing of our senior revolving credit and letter of credit facility that was due March 2016 (“Senior Credit Facility”), which included the issuance of an additional $60.0 million of 2019 Notes, in February 2015.
Loss on Debt Extinguishment
We recorded a loss on debt extinguishment of $0.6 million in the three months ended June 30, 2016 associated with the redemption of $12.5 million aggregate principal amount of 2019 Notes and the repurchase of $3.0 million aggregate principal amount of 2019 Notes. We also recorded a less than $0.1 million gain on debt extinguishment in the quarter ended March 31, 2016 associated with the below par repurchase of $4.2 million aggregate principal amount of 2019 Notes and a $0.5 million loss on debt extinguishment in the quarter ended March 31, 2015 associated with the refinancing of our Senior Credit Facility. See Note 6,  Long-Term Debt  to our consolidated financial statements included under Item 1 of this Quarterly Report on Form 10-Q for further disclosure.
Loss on Derivative Instruments
We were party to an interest rate derivative agreement for an interest rate swap that was not considered to be an effective cash flow hedge, which matured in the quarter ended March 31, 2016. We recognized the change in fair value of the interest rate swap along with any cash settlements through earnings as a (gain) or loss on derivative instruments.
Provision for Income Taxes
Our provision for income taxes decreased $0.1 million quarterly and $0.8 million year-to-date. The provision for income taxes in the six months ended June 30, 2016 and June 30, 2015 includes $0.3 million and $0.4 million, respectively, of deferred tax provisions due mainly to the increase in 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.
In connection with New York State’s (“State”) audit of our tax returns for fiscal years ended April 30, 2011 through April 30, 2013, the State had alleged that we were not permitted to file a single combined corporation franchise tax return with our subsidiaries. During the quarter ended March 31, 2015, as a result of discussions with the State, we decided to settle the audit for an amount less than 8.0% of the total cumulative alleged liability in order to minimize the out-of-pocket costs and potential litigation. As a result of these discussions, we recorded a $0.2 million gross increase in uncertain tax positions in the quarter ended March 31, 2015 related to the settlement with the State. This settlement was finalized in August 2015 for $0.2 million. As a result of these discussions, as well as a net unfavorable reversal of a portion of other positions due to the expiration of the statute of limitations, we recorded an increase in the reserve for uncertain tax positions of $0.4 million during the quarter ended March 31, 2015. During the quarter ended March 31, 2016, we recorded a decrease in the reserve for uncertain tax positions of $0.3 million due to the expiration of the statute of limitations on other positions.

Eastern Region
Operating income decreased $0.1 million quarterly and $0.4 million year-to-date. After taking into consideration the $1.2 million impact of the Maine Energy divestiture reserve reversal in the quarter ended March 31, 2015, our operating performance in the three and six months ended June 30, 2016 improved due to the revenue growth outlined above, partially offset by the following cost changes:
 
•	 	Cost of operations: Cost of operations increased $1.4 million quarterly and $5.9 million year-to-date primarily due to the following: higher third-party disposal costs associated with higher collection and, to a lesser extent, higher disposal volumes, which decreased quarterly, but increased on a year-to-date basis, from organic customer growth; higher direct operational costs (including gas control and other landfill operating costs, higher equipment rental costs, and higher vehicle self-insurance costs); and higher facility maintenance and repair costs. These costs were partially offset by: lower diesel fuel costs; lower landfill operating lease amortization due to a lower rate and lower tons at our Southbridge landfill; lower host royalty fees at our Southbridge landfill; and lower fleet maintenance costs.	
 
•	 	Depreciation and amortization: Depreciation and amortization expense increased $0.4 million quarterly and $1.3 million year-to-date primarily due to an increase in the amortization rate at our Southbridge landfill and higher landfill tons on a year-to-date basis.	
Western Region
Operating income increased $2.5 million quarterly and $0.5 million year-to-date. Operating income for the three and six months ended June 30, 2015 was favorably impacted by the $0.7 million quarterly impact associated with a gain on the divestiture of a business and the $3.8 million year-to-date impact of the 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. After taking this into consideration, our operating performance in the three and six months ended June 30, 2016 improved due to the year-to-date revenue growth outlined above and the following cost changes:
 
•	 	Cost of operations: Cost of operations decreased $5.0 million quarterly and $3.8 million year-to-date primarily due to the following: lower third-party disposal and hauling costs associated with lower collection and disposal volumes; lower healthcare costs on a quarterly basis related to plan improvements and lower overall claim activity; lower labor and related benefit costs on lower volumes; and lower diesel fuel costs.	
 
•	 	Depreciation and amortization: Depreciation and amortization expense decreased $0.8 million quarterly and $1.0 million year-to-date primarily due to lower landfill volumes.	
Recycling
Improved operating performance is the result of revenue growth outlined above, partially offset by the following cost changes:
 
•	 	Cost of operations: Cost of operations increased $0.6 million quarterly and $0.5 million year-to-date primarily due to higher maintenance costs, partially offset by lower purchased material costs.	
Other
Improved operating performance is primarily the result of our Organics business. Operating income for our Organics business improved by $0.7 million quarterly and year-to-date due to the revenue growth outlined above, partially offset by higher cost of operations associated with higher hauling and transportation costs.

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.

A summary of the most significant items affecting the change in our operating cash flows follows:
 
•	 	Improved operational performance in the six months ended June 30, 2016 as revenues increased by $9.8 million, whereas cost of operations decreased $1.0 million and general and administration expenses increased $1.8 million.	
 
•	 	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 the six months ended June 30, 2016 was the result of the favorable cash flow impacts associated with accounts receivable and accounts payable, partially offset by the unfavorable cash flow impacts associated with prepaid expenses, inventories and other assets and accrued expenses and other liabilities.	
Net cash used in investing activities.
A summary of the most significant items affecting the change in our investing cash flows follows:
 
•	 	Capital expenditures. As expected, capital expenditures were $7.2 million higher in the six months ended June 30, 2016, primarily due to increased spend on various landfill development projects and business growth, as well as higher fleet, machinery, equipment and container purchases.	
 
•	 	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 the six months ended June 30, 2015.	
 
•	 	Acquisitions, net of cash acquired. We acquired three transfer stations in our Western region during the three months ended June 30, 2016 for total consideration of $2.8 million, including $2.4 million in cash.	
Net cash used in financing activities.

We had both a decrease in debt borrowings of $105.7 million, and debt payments of $106.6 million, associated primarily with: the issuance of an additional $60.0 million of 2019 Notes and the refinancing of our Senior Credit Facility in the six months ended June 30, 2015; and the repurchase or redemption, as applicable, and retirement of $19.7 million aggregate principal amount of 2019 Notes in order to maximize interest savings by paying down our most expensive debt.	
 
33

•	 	Change in restricted cash. In the three months ended June 30, 2016, we obtained $3.0 million of restricted cash from the issuance of $15.0 million aggregate principal amount of New York Bonds 2016 and subsequently used $2.2 million of these funds to pay down senior secured asset-based revolving credit and letter of credit facility due February 2020 (“ABL Facility”) borrowings for costs incurred to fund certain capital projects in the state of New York. We also used the remaining $1.3 million of restricted cash associated with the issuance of FAME Bonds 2015 in the six months ended June 30, 2016 to pay down ABL Facility borrowings for costs incurred to fund certain capital projects in the state of Maine. In the six months ended June 30, 2015, we used $5.7 million of the restricted cash associated with the issuance of the New York State Environmental Facilities Corporation Solid Waste Disposal Revenue Bond Series 2014 (“New York Bonds 2014”) to pay down ABL Facility borrowings used to finance certain capital projects in the state of New York.	
 
•	 	Payments of debt issuance costs. We made $8.1 million of debt issuance cost payments in the six months ended June 30, 2015 related to the issuance of an additional $60.0 million of 2019 Notes and the refinancing of our Senior Credit Facility, as compared to $0.7 million of debt issuance cost payments in the six months ended June 30, 2016 related primarily to the issuance of New York Bonds 2016.	
 
•	 	Distribution to noncontrolling interest holder. We distributed $1.5 million in the six months ended June 30, 2015 to Altela, Inc. associated with the disposal of certain assets of CARES as a part of the dissolution of the business.	
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 London Interbank Offered Rate (“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 June 30, 2016. 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 June 30, 2016, 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	  	Twelve Months Ended
June 30, 2016	 	  	Covenant Requirements
at June 30, 2016	 	
Minimum consolidated EBITDA (1)	  	$	117.2	  	  	$	75.0 Min.	  	
 
(1)	Minimum consolidated EBITDA is based on operating results for the twelve months preceding the measurement date, June 30, 2016. Based on the minimum consolidated EBITDA, our consolidated leverage ratio, as defined in the ABL Facility agreement, was 4.43 as of June 30, 2016. 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.	
 
34

 	A reconciliation of net cash provided by operating activities to minimum consolidated EBITDA is as follows (in millions):	

 	  	Twelve Months Ended
June 30, 2016	 	
Net cash provided by operating activities	  	$	82.2	  	
 	 	
Changes in assets and liabilities, net of effects of acquisitions and divestitures	  	 	(2.7	) 	
Divestiture transactions	  	 	(0.1	) 	
Gain on sale of property and equipment	  	 	0.6	  	
Loss on debt extinguishment	  	 	(1.0	) 	
Stock based compensation, net of excess tax benefit	  	 	(3.2	) 	
Impairment of investments	  	 	(2.1	) 	
Interest expense, less amortization of debt issuance costs and discount on long-term debt	  	 	36.1	  	
Provision for income taxes, net of deferred taxes	  	 	(0.2	) 	
EBITDA adjustment as allowed by the ABL Facility agreement	  	 	0.1	  	
Other adjustments as allowed by the ABL Facility agreement	  	 	7.5	  	
 	  	 	 	 	
Minimum consolidated EBITDA	  	$	117.2	  	
 	  	 	 	 	
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 June 30, 2016, our borrowing availability was greater than the minimum availability threshold as follows (in millions):

 	  	Amount	 	  	Minimum Availability
Threshold	 	
Availability (2)	  	$	56.3	  	  	$	23.8	  	
 
(2)	As of June 30, 2016, borrowing availability was calculated as a borrowing base of $138.4 million, less revolver borrowings of $55.8 million, less outstanding irrevocable letters of credit totaling $26.3 million, at which date no amount had been drawn.	
As of June 30, 2016, 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	  	Twelve Months Ended
June 30, 2016	 	  	Limits at
June 30, 2016	
Minimum fixed charge coverage ratio	  	 	1.61	  	  	1.00 Min.	
Maximum consolidated first lien leverage ratio	  	 	0.51	  	  	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 June 30, 2016, 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 the three months ended June 30, 2016, we completed a financing transaction involving the issuance by the New York State Environmental Facilities Corporation of $15.0 million aggregate principal amount of New York Bonds 2016.
As of June 30, 2016, we had outstanding $40.0 million aggregate principal amount of New York Bonds 2014 and New York Bonds 2016 issued by the New York State Environmental Facilities Corporation under the indenture dated December 1, 2014 (collectively, the “New York Bonds”). The New York Bonds 2014 accrue interest at 3.75% per annum through December 1, 2019, at which time they may be converted from a fixed rate to a variable rate. The New York Bonds 2016 accrue interest at 3.125% per annum through May 31, 2026, at which time they may be converted from a fixed rate to a variable rate. The New York Bonds, which are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, require interest payments on June 1 and December 1 of each year and mature on December 1, 2044. We borrowed the proceeds of the New York Bonds to finance or refinance certain capital projects in the state of New York and to pay certain costs of issuance of the New York Bonds. As of June 30, 2016, we have $0.8 million of restricted cash reserved for repayment of certain capital projects in the state of New York.
Maine Bonds
As of June 30, 2016, 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 June 30, 2016, 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 the state of Maine.
As of June 30, 2016, 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. 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 certain costs of the issuance of the FAME Bonds 2015.
Vermont Bonds
As of June 30, 2016, 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.
 
36

New Hampshire Bonds
As of June 30, 2016, we had outstanding $11.0 million aggregate principal amount of Solid Waste Disposal Revenue Bonds Series 2013 issued by the Business Finance Authority of the State of New Hampshire (“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 the six months ended June 30, 2016, we continued our efforts to redeem or repurchase, as applicable, and permanently retire our 2019 Notes in order to maximize interest savings by paying down our most expensive debt. We redeemed and permanently retired $12.5 million aggregate principal amount of 2019 Notes at a redemption price equal to 101.938% of the principal amount thereof plus accrued and unpaid interest thereon; we repurchased and permanently retired $3.0 million aggregate principal amount of 2019 Notes at a repurchase price of $102.25; and we repurchased and permanently retired $4.2 million aggregate principal amount of 2019 Notes at a repurchase price of $96.75. Additionally, in July 2016, we continued to maximize interest savings by paying down our most expensive debt when we repurchased and retired an additional $5.0 million aggregate principal amount of 2019 Notes at a repurchase price of $102.00.
As of June 30, 2016, we had outstanding $350.6 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 June 30, 2016, 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 the registration statement.
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.
 
37

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.
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.
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 June 30, 2016, that dollar amount was $51.0 million.
Critical Accounting Policies and Estimates
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 Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2015.
 
38

Adoption of New Accounting Pronouncements
For a description of the new accounting standards adopted that may affect us, see Note 2 to our consolidated financial statements included under Part I, Item 1 of this Quarterly Report on Form 10-Q.
 
ITEM 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK	
Information about market risks as of June 30, 2016, does not differ materially from that discussed in Item 7A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2105.
 
ITEM 4.	CONTROLS AND PROCEDURES	
a) 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 June 30, 2016. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of June 30, 2016, 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.
b) Changes in internal controls over financial reporting. No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the three months ended June 30, 2016 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II.
 
ITEM 1.	LEGAL PROCEEDINGS	
Legal Proceedings
In the ordinary course of our business and as a result of the extensive governmental regulation of the solid waste industry, we are subject to various judicial and administrative proceedings involving state and local agencies. In these proceedings, an agency may seek to impose fines or to revoke or deny renewal of an operating permit held by us. From time to time, we may also be subject to actions brought by special interest or other groups, adjacent landowners or residents in connection with the permitting and licensing of landfills and transfer stations, or allegations of environmental damage or violations of the permits and licenses pursuant to which we operate. In addition, we may be named defendants in various claims and suits pending for alleged damages to persons and property, alleged violations of certain laws and alleged liabilities arising out of matters occurring during the ordinary operation of a waste management business.
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 ( “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 (“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 alleged that we had the obligation to provide a specialized type of wood fuel to the Facility or, alternatively, that we owed a “Fuel Replacement Fee” of up to $2.0 million a year (subject to the possibility of certain credits against such payments). The Contract was to expire in 2036.
On or about February 10, 2016, we reached an agreement in principle with MFGR to dismiss the Lawsuit with prejudice, and to resolve all outstanding claims of any nature including future claims which could arise under the Contract, and a Joint Stipulation of Dismissal with Prejudice was filed with the Superior Court on April 15, 2016. On or about April 12, 2016, the Parties entered into a Settlement Agreement (“SA”) along with other ancillary agreements. Pursuant to the SA, we paid MFGR $1.3 million upon execution of the SA, and will pay $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 recorded a reserve of $2.6 million that included a contract settlement charge of $1.9 million and operating expenses of $0.7 million recorded in the fiscal year ended December 31, 2015. As of June 30, 2016, $1.4 million of this reserve remains outstanding. We have also reserved less than $0.1 million for legal costs associated with the Lawsuit and SA as of June 30, 2016.
We have also entered 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 Landfill”), and MFGR has entered into a waste disposal agreement at market prices with us for the disposal at Juniper Ridge Landfill of waste materials produced in the demolition or re-purposing of the Facility.
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 matters represents our potential or outstanding material claims.
Southbridge Recycling & Disposal Park, Inc.
In October 2015, our Southbridge Recycling and Disposal Park, Inc. (“SRD”) subsidiary reported to the Massachusetts Department of Environmental Protection (“MADEP”) results of analysis of samples collected pursuant to our existing permit from private drinking water wells located near the Town of Southbridge, Massachusetts Landfill (“Southbridge Landfill”), which is operated by SRD. Those results indicated the presence of contaminants above the levels triggering notice and
 
40

response obligations under MADEP regulations. In response to those results, we are carrying out an Immediate Response Action pursuant to state law. Further, we have implemented a plan to analyze and better understand the groundwater near the Southbridge Landfill and we are investigating with the objective of identifying the source or sources of the elevated levels of contamination measured in the well samples. If it is determined that some or all of the contamination originated at the Southbridge Landfill, we will work with the Town of Southbridge (“Town”), the Southbridge Landfill owner and operator of an unlined portion of the landfill prior to our operation of a double-lined portion of the Landfill commencing in 2004, to evaluate and allocate the liabilities related to that contamination. In July 2016, we sent correspondence to the Town pursuant to Chapter 21E of Massachusetts General Laws advising the Town that we have incurred expenditures of $1.5 million, that we expect the Town to reimburse us for such costs, and for the Town to be responsible for any such costs in the future, as well as any other costs or liabilities resulting from the release of contaminants from the Southbridge Landfill.
In February 2016, we received a Notice of Intent to Sue under the Resource Conservation and Recovery Act from a law firm representing residents from approximately 40 homes located in the vicinity of the Southbridge Landfill, indicating its intent to file suit against us. We would also expect the Town to be responsible for any costs or liabilities associated with this suit relative to alleged contamination originating from the Southbridge Landfill pursuant to Chapter 21E. The existence of those contaminants and any related lawsuit or other action could delay our ongoing permitting activities at Southbridge Landfill and result in costs and liabilities, each of which could have a material impact on our results of operations and financial condition.
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.
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%. A summary of the changes to the environmental remediation liability associated with the Potsdam environmental remediation liability follows:

ITEM 1A.	RISK FACTORS	
Our business is subject to a number of risks, including those identified in Item 1A, “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, that could have a material effect on our business, results of
