NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(in thousands, except for per share data)

1. BASIS OF PRESENTATION

Casella Waste Systems, Inc. (“Parent”), 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 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 our 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 customer accounts, discontinued operations and earnings from equity method investees are included in our Other segment.

The consolidated financial statements as of October 31, 2014 and for the three and six months ended October 31, 2014 and 2013 are unaudited. The accompanying consolidated financial statements, which include the accounts of the Parent, our wholly-owned subsidiaries and certain 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 applicable. Assets and liabilities of discontinued operations and assets held-for-sale are segregated from those of continuing operations and reported in separate captions in the balance sheet, as applicable. The results of operations that have been disposed of or classified as held-for-sale and qualify for discontinued operations accounting are reported in discontinued operations, as applicable. Our significant accounting policies are more fully discussed in Item 8 of our Annual Report on Form 10-K for the year ended April 30, 2014, which was filed with the SEC on June 26, 2014.

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 October 31, 2014 may not be indicative of the results for any other interim period or the eight-month transition period described below. 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 year ended April 30, 2014.

9

We consider events or transactions that have occurred after the consolidated balance sheet date of October 31, 2014, but prior to the filing of the consolidated financial statements with the SEC on this Quarterly Report on Form 10-Q. We have evaluated subsequent events through the filing date of this Quarterly Report on Form 10-Q with the SEC.

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 will become effective for our fiscal year beginning January 1, 2015 and ending December 31, 2015. We intend to file a Transition Report on Form 10-KT for the eight-month transition period ending December 31, 2014 (“Transition Period”). This Quarterly Report on Form 10-Q for the three and six month periods ended October 31, 2014 is for the second quarter of the Transition Period.

New Accounting Pronouncements Pending Adoption

Revenue Recognition

In May 2014, the Financial Accounting Standards Board (“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 that reporting period, beginning after December 15, 2016 under either full or modified retrospective adoption. Early application is not permitted. We are currently assessing the potential impact of these changes to our consolidated financial statements as a result of adopting this standard.

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 or a group of components of an entity is required to be reported in discontinued operations once the component of an entity 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 that reporting period, beginning after December 15, 2014, with early adoption permitted, but only for disposals, or classifications as held for sale, that have not been reported in financial statements previously issued or available for issuance. Adoption of this standard may impact the presentation of, and disclosures in, our consolidated financial statements and notes thereto.

Adoption of New Accounting Pronouncements

Income Taxes

In July 2013, the FASB issued an accounting standards update for the reporting of an unrecognized tax benefit, or portion thereof, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The update provides an exception, requiring the unrecognized tax benefit to be presented in the financial statements as a liability when the carryforward is not available at the reporting date under the tax laws to settle additional income taxes that would result in the disallowance of a tax provision or the tax laws do not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose. This guidance is effective prospectively, with retrospective application permitted, for annual reporting periods, and interim reporting periods within that reporting period, beginning after December 15, 2013, with early adoption permitted. We adopted this guidance effective May 1, 2014 and it has not had, and we believe will not have, a material impact on our consolidated financial statements.

2. BUSINESS COMBINATIONS

During the six months ended October 31, 2014, we acquired one solid waste hauling operation in each of the Eastern and Western regions, whereas, during the six months ended October 31, 2013, we acquired three solid waste hauling operations, two of which are located in the Western region and one of which is located in the Eastern region, and an industrial service

management business (included in the Other segment). The operating results of these businesses are included in the accompanying 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. Intangible assets other than goodwill that are subject to amortization include acquired client lists and non-compete agreements, which are often negotiated as a part of our business combinations. These are amortized over a five to ten year period from the date of acquisition. Amounts recorded to goodwill are in most cases expected to be deductible for tax purposes.

The purchase price paid for these acquisitions during the six months ended October 31, 2014 and 2013 and the allocation of the purchase price is as follows:

	Six Months Ended October 31,
	2014		2013
Purchase Price:
Cash used in acquisitions, net of cash acquired	$	314	$	2,793
Other non-cash considerations		—		245
Contingent consideration and holdbacks		67		1,556
Total		381		4,594
Equipment		99		495
Other liabilities, net		—		(38	)
Intangible assets		251		1,865
Fair value of assets acquired and liabilities assumed		350		2,322
Excess purchase price to be allocated to goodwill	$	31	$	2,272

The following unaudited pro forma combined information shows the results of our continuing operations for the three and six months ended October 31, 2014 and 2013 as though each of the acquisitions completed in the six months ended October 31, 2014 and the twelve months ended April 30, 2014 had occurred as of May 1, 2013.

The pro forma results set forth in the table above have been prepared for comparative purposes only and are not necessarily indicative of the actual results of operations had the acquisitions occurred as of May 1, 2013 or the results of our future operations. Furthermore, the pro forma results do not give effect to all cost savings or incremental costs that may occur as a result of the integration and consolidation of the completed acquisitions.

4. ACCRUED 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. The changes to accrued final capping, closure and post-closure liabilities for the six months ended October 31, 2014 and 2013 are as follows:

	Six Months Ended October 31,
	2014			2013
Beginning balance	$	44,654		$	43,170

Tax-Exempt Financing Transactions

New Hampshire Bonds

In the three months ended October 31, 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 of New Hampshire Bonds from a variable rate to a fixed term rate and the issuance of an additional $5,500 principal amount of fixed term rate New Hampshire Bonds. We borrowed the additional proceeds of the New Hampshire Bonds to repay borrowings under our senior secured revolving credit facility (“Revolver”) for qualifying property, plant and equipment assets purchased in New Hampshire since October 5, 2011.

6. 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 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 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 ASC 450-20.

New York Attorney General Matter

In July 2014, we entered into an Assurance of Discontinuance (“AOD”) with the office of the New York Attorney General (“NYAG”) in connection with our commercial practices in certain specified counties in New York. The AOD requires, among other things, that we modify our service contracts for two to ten yard containers with our commercial customers in the specified counties by shortening the initial term of such contracts to two years and providing for only one extension term of one year. We also agreed (i) to limit the liquidated damages to be paid by a customer, if a customer prematurely terminates its contract with us, to three months in year one of the contract and one month in year two or any extension year of the contract, (ii) to provide the NYAG with post-acquisition notice within thirty days of an acquisition of a provider of solid waste services with a value of $350 or more and (iii) to pay the State of New York the sum of $100. We recorded a charge of $100, included in general and administration, in the first quarter of the Transition Period. The counties in New York covered by the AOD are Allegany, Cattaraugus, Chautauqua, Chemung, Clinton, Franklin, Schuyler, St. Lawrence, Steuben, and Tompkins. This matter is now closed other than with respect to ongoing compliance.

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. The Draft Order seeks a civil administrative cash penalty of $67 and an additional administrative penalty in the form of a Supplemental Environmental Project in the amount of $201. We are working with the MADEP to address these allegations to arrive at an appropriate resolution thereof. It is probable that we will incur a loss with respect to this matter and as a result we recorded a charge of $172 in general and administration in the six months ended October 31, 2014.

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 represent our potential or outstanding material claims.

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. It is unlikely that any significant costs relating to onsite remediation will be incurred until the fiscal year ending December 31, 2016. WSI and NiMo are jointly and severally liable for the total cost to remediate.

In September 2011, the DEC settled its environmental claim against the estate of the former GM (known as “Motors Liquidation Trust”) for future remediation costs relating to the WSI site for face value of $3,000. In addition, in November 2011 we settled our own claim against the Motors Liquidation Trust for face value of $100. These claims will be paid by GM in warrants to obtain stock of the reorganized GM. GM has issued warrants to us beginning in May 2013 and at this time there is no way to accurately estimate when the remainder of these claims will be paid. We have not assumed that any future proceeds from the sale of securities received in payment of these claims will reduce our exposure.

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. Our expenditures could be significantly higher if costs exceed estimates. We inflate the estimated costs in current dollars until the expected time of payment and discount the total cost to present value using a risk free interest rate of 2.0%. The changes to the environmental remediation liability associated with the Potsdam environmental remediation liability for the six months ended October 31, 2014 and 2013 are as follows:

	Six Months Ended October 31,
	2014			2013
Beginning balance	$	5,320		$	5,297
Obligations incurred		—			31
Accretion expense		69			69
Payments		(270	)		—
Ending balance	$	5,119		$	5,397

Southbridge Landfill Environmental Remediation Liability

On or about August 24, 2013, we experienced the movement of stockpiled earth at our Southbridge landfill in Southbridge, Massachusetts. The stockpiled materials consisted of soil removed and relocated to create space for the construction of additional landfill airspace at our Southbridge landfill. The earth had been relocated and stored during the fall, winter and spring construction season of the fiscal year ended April 30, 2013 (“fiscal year 2013”).

The movement caused some of the stockpiled earth to enter wetlands on property owned by us. On or about August 29, 2013, we notified the MADEP, and the Towns of Southbridge and Charlton, Massachusetts, of the occurrence of the movement. On or about September 6, 2013, MADEP issued a “Unilateral Administrative Order” (“UAO”) requiring us to provide MADEP with a plan to remove any materials deposited in the wetlands as a result of the movement (“Plan”). On or about October 3, 2013, we submitted the Plan to MADEP, and on or about October 15, 2013, MADEP approved the Plan and verbally issued permission for us to implement the Plan. We have implemented the Plan under the supervision of MADEP.

15

In January 2014, we received correspondence from the Massachusetts’ Office of the Attorney General (“MAAG”), advising us that the MAAG intended to schedule a meeting with us to discuss this incident, and to possibly file suit against us for violation of the Massachusetts Wetlands Protection, Clean Air and Solid Waste Acts. We met with the MAAG in March 2014 and again in July 2014 to discuss our ongoing remediation effort, and the parties are continuing to have discussions regarding the resolution of this matter.

On or about April 25, 2014, we notified MADEP and other interested parties that areas of sloughing had occurred in a plateau created as part of new cell construction at our Southbridge landfill. Some of the same contractors and technical advisors that were involved in the initial movement of stockpiled earth are also involved in the new cell construction that includes this area of sloughing. We repaired the areas of sloughing on April 25, 2014 and no damage occurred in the abutting wetlands. On May 9, 2014, MADEP issued a UAO directing us to ensure that the areas of sloughing at the plateau were repaired and to take steps to ensure that there would be no incursion into the wetlands, and requiring that we undertake corrective actions to ensure the stability of the plateau. Prior to MADEP’s issuance of the latest UAO, we were in the process of awarding a contract to a soil remediation company to undertake corrective actions and ensure stability at the plateau. This contract was awarded, and the work was finished in September 2014.

We anticipate that the execution of the Plan and related matters will involve remediation costs of approximately $2,997 and that such costs could be higher if actual costs exceed estimates. We have provided our insurer with notice of the Plan, and the costs expended by us to date to comply with the Plan. We have also provided notice to certain of our contractors and technical advisors that the movement has occurred, that significant remediation costs will be incurred in executing the Plan and related matters, and that we expect our contractor and technical advisor to assist in the execution of the Plan and related matters, to share in the remediation costs thereof as responsible parties, and to provide notice to their own insurers. We are currently engaged in discussion with our contractor and technical advisor regarding resolution of these matters. We believe that a loss in the range of $850 to $2,997, including the resolution of our discussions with the MAAG, after taking into account amounts we expect to be reimbursed by our insurer and third-parties, is probable and have therefore recorded a charge of $375 in the three months ended October 31, 2014. We had previously recorded a charge of $400 in the fiscal year ended April 30, 2014 (“fiscal year 2014”) and a charge of $75 in the first quarter of the Transition Period as an environmental remediation charge.

7. STOCKHOLDERS’ EQUITY

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 other similar events), plus (ii) such additional number of shares of Class A common stock as are currently subject to options granted under our 1993 Incentive Stock Option Plan, 1994 Non-statutory Stock Option Plan, 1996 Option Plan, and 1997 Stock Option Plan (“Prior Plans”), which are not actually issued under the Prior Plans because such options expire or otherwise result in shares not being issued. As of October 31, 2014, there were 994 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.

Stock Options

Options 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, options granted have a term not to exceed ten years and vest over a one to four year period from the date of grant.

16

A summary of stock option activity for the six months ended October 31, 2014 is as follows:

	Stock Options			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (years)		Aggregate Intrinsic Value
Outstanding, April 30, 2014		1,368		$	8.65
Granted		200		$	4.86
Exercised		(33	)	$	4.30
Forfeited		(145	)	$	13.06
Outstanding, October 31, 2014		1,390		$	7.75		5.4	$	248
Exercisable, October 31, 2014		849		$	9.73		3.2	$	139
Expected to vest, October 31, 2014		1,389		$	7.76		5.4	$	248

Stock-based compensation expense for stock options was $165 and $275 during the three and six months ended October 31, 2014, respectively, as compared to $88 and $203 during the three and six months ended October 31, 2013.

As of October 31, 2014, total unrecognized stock-based compensation expense related to outstanding stock options was $1,200, which will be recognized over a weighted average period of 1.8 years.

Our calculations of stock-based compensation expense associated with stock options granted in the three and six months ended October 31, 2014 were made using the Black-Scholes valuation model. The fair value of stock options grants were estimated assuming no expected dividend yield using the following weighted average assumptions for the three and six months ended October 31, 2014 (no stock options granted in the three and six months ended October 31, 2013):

	Three Months Ended October 31, 2014			Six Months Ended October 31, 2014
Stock Options:
Expected life		7.13 years			7.00 years
Risk-free interest rate		2.15	%		2.15	%
Expected volatility		82.08	%		82.75	%

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.

Other Stock Awards

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 on the third fiscal year-end following the grant date and are based on our attainment of a targeted average return on net assets as of the vesting date.

17

A summary of restricted stock, restricted stock unit and performance stock unit activity for the six months ended October 31, 2014 is as follows:

	Restricted Stock, Restricted Stock Units, and Performance Stock Units (1)			Weighted Average Grant Price		Weighted Average Remaining Contractual Term (years)		Aggregate Intrinsic Value
Outstanding, April 30, 2014		1,077		$	4.77
Granted		370		$	4.91
Class A Common Stock Vested		(363	)	$	4.89
Forfeited		(32	)	$	4.39
Outstanding, October 31, 2014		1,052		$	4.79		1.7	$	191
Expected to vest, October 31, 2014		927		$	4.40		1.6	$	173

(1) Performance stock units are included at the 100% attainment level. Attainment of maximum annual returns on net assets could result in the issuance of an additional 251 shares of Class A common stock.

During the six months ended October 31, 2014, we awarded certain employees restricted stock units, which vest incrementally over a three year period beginning on the first anniversary of the date of grant and are based on continued employment.

Stock-based compensation expense related to restricted stock, restricted stock units and performance stock units was $465 and $897 during the three and six months ended October 31, 2014, respectively, as compared to $475 and $966 during the three and six months ended October 31, 2013.

As of October 31, 2014, total unrecognized compensation expense related to outstanding restricted stock and restricted stock units was $2,685, which will be recognized over a weighted average period of 1.9 years. Maximum unrecognized stock-based compensation expense at October 31, 2014 related to outstanding performance stock units, and subject to the attainment of targeted maximum annual returns on net assets, was $2,479 to be recognized over a weighted average period of 0.5 years. We do not expect to recognize any compensation expense as of October 31, 2014 related to outstanding performance stock units based on our expected attainment levels.

We also recorded $16 and $37 of stock-based compensation expense related to our Employee Stock Purchase Plan during the three and six months ended October 31, 2014, respectively, as compared to $15 and $39 during the three and six months ended October 31, 2013.

Accumulated Other Comprehensive Income

The change in the balance of accumulated other comprehensive income, which is included as a component of our stockholders’ deficit, for the six months ended October 31, 2014 is as follows:

	Marketable Securities
Beginning balance, April 30, 2014	$	39
Other comprehensive income, net of tax before reclassifications		6

9. 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 include cash and cash equivalents, restricted cash, trade receivables, restricted trust and escrow accounts held in trusts with various banks as collateral for our obligations relative to landfill final capping, closure and post-closure costs, interest rate derivatives, trade payables and long-term debt. The carrying values of cash and cash equivalents, restricted cash, trade receivables and trade payables approximate their respective fair values due to their short-term nature. The fair value of the restricted trust and escrow accounts are included as restricted assets in the Level 1 tier below. The fair values of the interest rate derivatives, included in the Level 2 tier below, are calculated based on the three month LIBOR yield curve that is observable at commonly quoted intervals for the full term of the interest rate swaps, adjusted by the credit risk of us and our counter-parties based on observable credit default swap rates. We recognize all derivatives on the balance sheet at fair value.

20

As of October 31, 2014 our assets and liabilities measured at fair value on a recurring basis included the following:

	Fair Value Measurement at October 31, 2014 Using:

Fair Value of Debt

As of October 31, 2014, the fair value of our fixed rate debt, including our 7.75% senior subordinated notes due 2019 (“2019 Notes”), the Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-2 (“FAME Bonds 2005R-2”), the Vermont Economic Development Authority Solid Waste Disposal Long Term Revenue Bonds Series 2013 (“Vermont Bonds”), and the New Hampshire Bonds was approximately $382,460 and the carrying value was $373,400. The fair value of the 2019 Notes is 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 Vermont 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 that utilizes pricing models and pricing systems, mathematical tools and judgment to determine the evaluated price for the security based on the market information of each of the bonds or securities with similar characteristics. As of October 31, 2014, the fair value of our Revolver is considered to be Level 2 within the fair value hierarchy as its fair value approximated its carrying value of $144,300 based on current borrowing rates for similar types of borrowing arrangements.

10. SEVERANCE AND REORGANIZATION

In the three and six months ended October 31, 2013, we recorded charges totaling $53 and $161, respectively, for severance costs associated with various planned reorganization efforts including the divestiture of Maine Energy Recovery Company LP (“Maine Energy”) discussed further in Note 11.

11. 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. The review consists of evaluating whether the business qualifies as a component of an entity for which the operations and cash flows are clearly distinguishable; whether it is anticipated that the cash flows of the component have been or will be eliminated from ongoing operations after the disposal transaction and by the end of the assessment period; and whether we will have any significant continuing involvement in the operations of the component after the disposal transaction. Planned business dispositions are presented as discontinued operations when all three criteria are met. Additionally, 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.

21

Businesses that qualify as held-for-sale are carried at the lower of their carrying value or fair value less costs to sell in the period the held-for-sale criteria are met. For a business that is classified as held-for-sale and meets the discontinued operations criteria, all initial or subsequent adjustments to the carrying value of the component are classified in discontinued operations.

Discontinued Operations

In fiscal year 2013, we initiated a plan to dispose of KTI BioFuels, Inc. (“BioFuels”), a construction and demolition material processing facility located in Lewiston, Maine, 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 is being 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 is recorded in current and non-current assets of discontinued operations in the consolidated balance sheets. We recognized a $378 loss on disposal of discontinued operations in the first quarter of 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) income before income taxes attributable to discontinued operations for the three and six months ended October 31, 2014 and 2013, respectively, are as follows:

	Three Months Ended October 31,					Six Months Ended October 31,
	2014		2013			2014		2013
Revenues	$	—	$	5		$	—	$	3,316
(Loss) income before income taxes	$	—	$	(45	)	$	—	$	284

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

Divestiture Transactions

In the first quarter of fiscal year 2013, we executed a purchase and sale agreement (“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 is being paid to us in equal 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 are nearly complete with site remediation under the auspices and in accordance with work plans approved by the Maine Department of Environmental Protection (“MEDEP”), and the U.S. Environmental Protection Agency (“USEPA”). The time for completion of this project has been consensually extended by us and the City of Biddeford, and we expect to complete this project and transfer ownership of the real property to the City of Biddeford by, or before, spring 2015. Based on incurred costs to date and estimates regarding the remaining costs to fulfill our obligation under the Agreement, a potential gain on divestiture of up to $1,000 is possible.

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. Revenues associated with our solid waste operations are derived mainly from collection, transfer, disposal, landfill, landfill gas-to-energy 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 customer accounts, discontinued operations, and earnings from equity method investees are included in our Other segment.

This Quarterly Report on Form 10-Q and, in particular, this Management’s Discussion and Analysis of Financial Condition and Results of Operations may contain or incorporate a number of forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act of 1934, as amended (“Exchange Act”), including:

• expected liquidity and financing plans;

• expected future revenues, operations, expenditures and cash needs;

• fluctuations in the commodity pricing of our recyclables, increases in landfill tipping fees and fuel costs and general economic and weather conditions;

• projected future obligations related to final capping, closure and post-closure costs of our existing landfills and any disposal facilities which we may own or operate in the future;

• our ability to use our net operating losses and tax positions;

• our ability to service our debt obligations;

• the projected development of additional disposal capacity or expectations regarding permits for existing capacity;

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 (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 customer accounts, discontinued operations, and earnings from equity method investees are included in our Other segment.

As of November 17, 2014, we owned and/or operated 35 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.

Accounting Period

In June 2014, we elected to change our fiscal year-end from April 30^th to December 31^st. The change in fiscal year will become effective for our fiscal year beginning January 1, 2015 and ending December 31, 2015. We intend to file a Transition Report on Form 10-KT for the eight-month transition period ending December 31, 2014 (“Transition Period”). This Quarterly Report on Form 10-Q for the three and six month periods ended October 31, 2014 is for the second quarter of the Transition Period.

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.

During the six months ended October 31, 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. During the six months ended October 31, 2013, we acquired three solid waste hauling operations, two of which are located in the Western region and one of which is located in the Eastern region, for total consideration of $2.1 million, including $1.5 million in cash, $0.2 million of other non-cash considerations and $0.4 million in holdbacks to the sellers. During the six months ended October 31, 2013, we also acquired an industrial service management business in the Other segment for total consideration of $2.5 million as of the acquisition date, including $1.3 million in cash, $0.3 million in holdbacks to the seller and $0.9 million in consideration, not to exceed $1.0 million, contingent upon the realization of a measure of operating income associated with certain prospective customer contracts within twelve months of closing.

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 other customers in the form of processing fees, tipping fees and commodity sales. Organics services, ancillary operations, major customer accounts, discontinued operations, and earnings from equity method investees are included in our “Other” reportable segment.

Our revenues are shown net of inter-company eliminations. The table below shows the percentages and dollars (in millions) of revenue attributable to services provided for the three and six months ended October 31, 2014 and 2013:

Solid waste revenues

Price.

• The price change component in quarterly total solid waste revenues growth period-to-period is the result of $0.8 million from favorable collection pricing and $0.1 million from favorable disposal pricing associated with our landfills.

• The price change component in year-to-date total solid waste revenues growth period-to-period is the result of $1.8 million from favorable collection pricing.

Volume.

• The volume change component in quarterly total solid waste revenues growth period-to-period is the result of $2.8 million from disposal volume increases (of which $2.5 million relates to higher transfer station volumes associated with a mix shift from landfills to transfer stations and two new transfer station contracts, $0.2 million relates to transportation and $0.1 million relates to landfills) and $0.5 million from collection volume increases.

• The volume change component in year-to-date total solid waste revenues growth period-to-period is the result of $7.8 million from disposal volume increases (of which $5.1 million relates to higher transfer station volumes associated with a mix shift from landfills to transfer stations and two new transfer station contracts, $2.3 million relates to landfills and $0.4 million relates to transportation) and $0.7 million from collection volume increases.

Commodity price and volume.

• The commodity price and volume change component in quarterly total solid waste revenues growth period-to-period is the result of $0.1 million from favorable commodity pricing within power generation and processing, more than offset by $0.3 million from lower power generation and processing commodity volumes.

• The commodity price and volume change component in year-to-date total solid waste revenues growth period-to-period is the result of $0.2 million from favorable commodity pricing within power generation and processing, more than offset by $0.5 million from lower power generation and processing commodity volumes.

40

Acquisitions and divestitures.

• The acquisitions and divestitures change component in quarterly and year-to-date total solid waste revenues growth period-to-period is the result of increased revenues from various business acquisitions, including several solid waste hauling operations and a transfer station, completed between August 2013 and September 2014.

Closed landfill.

• The closed landfill change component in quarterly and year-to-date total solid waste revenues growth period-to-period is the result of a landfill in the Eastern region that ceased operations in April 2014 in accordance with its permit.

Organics revenues

• The increase in quarterly and year-to-date revenues is the result of higher volumes associated with organic business growth.

Customer Solutions revenues

• The increase in quarterly revenues period-to-period is the result of $2.8 million from higher volumes and $0.2 million from the acquisition of an industrial service management business in September 2013.

• The increase in year-to-date revenues period-to-period is the result of $6.1 million from higher volumes and $1.0 million from the acquisition of an industrial service management business in September 2013.

Recycling revenues

• The increase in quarterly revenues period-to-period is primarily the result of higher commodity volumes and the acquisition of the remaining 50% membership interest of Tompkins County Recycling LLC (“Tompkins”) in December 2013.

• The increase in year-to-date revenues period-to-period is primarily the result of favorable commodity pricing in the market, higher commodity volumes and the acquisition of the remaining 50% membership interest of Tompkins in December 2013.

Operating Expenses

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.

Our cost of operations increased $7.8 million, or 1.1% as a percentage of revenues, and $18.1 million, or 1.0% as a percentage of revenues, when comparing the three and six months ended October 31, 2014 to the same periods in the prior fiscal year.

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

• Third-party direct costs increased $3.4 million and $9.3 million during the three and six months ended October 31, 2014, respectively, as compared to the same periods in the prior fiscal year due to: organic and acquisition growth in our Customer Solutions business, which has a higher inherent direct cost structure; higher volumes in our Organics business; higher collection and disposal volumes from organic customer growth and the acquisition of a transfer station in the Eastern region; and higher disposal volumes associated with two new transfer station contracts and the acquisition of various hauling operations in the Western region.

• Maintenance and repair costs increased $1.8 million and $3.6 million during the three and six months ended October 31, 2014, respectively, as compared to the same periods in the prior fiscal year due to: higher facility costs associated with hauling operations and certain landfills in our Eastern region and facility maintenance activities within our Recycling segment, and higher fleet repair and maintenance costs associated with hauling operations in our Western region.

41

• Labor and related benefit costs increased $2.0 million and $3.3 million during the three and six months ended October 31, 2014, respectively, as compared to the same periods in the prior fiscal year due to additional labor costs associated with higher collection volumes in the Eastern region and increased overall healthcare costs.

• Direct operational costs increased $0.6 million and $1.6 million during the three and six months ended October 31, 2014, respectively, as compared to the same periods in the prior fiscal year due to: higher depletion of landfill operating lease obligations associated with increased volumes received at our landfills in the Western region; an increase in landfill operating costs; and a lower gain on sale of fixed assets in the three and six months ended October 31, 2014.

General and Administration

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

Our general and administration expenses increased $0.1 million, or decreased 0.8% as a percentage of revenues, when comparing the three months ended October 31, 2014 to the same period in the prior fiscal year, and increased $1.9 million, or decreased 0.3% as a percentage of revenues, when comparing the six months ended October 31, 2014 to the same period in the prior fiscal year.

The period-to-period changes in general and administration can largely be attributed to the following:

• Labor and related benefit costs increased $0.3 million and $1.2 million during the three and six months ended October 31, 2014, respectively, as compared to the same periods in the prior fiscal year due to additional labor costs associated with growth in our Customer Solutions business and increased healthcare costs, partially offset by a reduction of incentive compensation.

• Professional fees increased $0.2 million and $0.6 million during the three and six months ended October 31, 2014, respectively, as compared to the same periods in the prior fiscal year due to the timing of accounting and auditing services associated with the change in fiscal year-end and higher legal costs associated with third-party legal advice, a legal settlement with the State of New York Attorney General’s Office (“NYAG”) and a charge accrued for a potential legal settlement with the Massachusetts Department of Environmental Protection (“MADEP”). See discussion in Legal Proceedings included under Part II, Item 1 of this Quarterly Report on Form 10-Q.

• Bad debt expense decreased $0.5 million and $0.3 million during the three and six months ended October 31, 2014, respectively, as compared to the same periods in the prior fiscal year due to a higher than normal bad debt expense in the prior fiscal year periods due to collectability issues associated with two disposal customers in the Western region.

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 incurred and all estimated future costs for landfill development, construction and asset retirement costs arising from closure and post-closure, 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 a economic benefit provided approach or a straight-line basis over the definitive terms of the related agreements.

42

The table below summarizes the components of depreciation and amortization expense for the three and six months ended October 31, 2014 and 2013 (in millions of dollars and as a percentage of revenues):

	Three Months Ended October 31,								Six Months Ended October 31,
	2014				2013				2014				2013
Depreciation expense	$	7.9	5.6	%	$	8.3	6.3	%	$	16.2	5.7	%	$	16.4	6.3	%
Landfill amortization expense		7.4	5.3	%		6.8	5.1	%		14.7	5.2	%		13.4	5.1	%
Other amortization expense		0.7	0.5	%		0.6	0.5	%		1.5	0.6	%		1.1	0.4	%
	$	16.0	11.4	%	$	15.7	11.9	%	$	32.4	11.5	%	$	30.9	11.8	%

The changes in the components of depreciation and amortization expense when comparing the three and six months ended October 31, 2014 to the same periods in the prior fiscal year can largely be attributed to the following:

• Landfill amortization expense increased $0.6 million and $1.3 million during the three and six months ended October 31, 2014, respectively, as compared to the same periods in the prior fiscal year due primarily 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 a $0.3 million increase in estimated final capping costs at a closed landfill in the Eastern region.

Environmental Remediation Charge

We recorded an environmental remediation charge of $0.4 million during the three and six months ended October 31, 2014, respectively, compared to $0.1 million during the three and six months ended October 31, 2013 associated with the environmental remediation at our Southbridge landfill in the Eastern region as discussed in Legal Proceedings included under Part II, Item 1 of this Quarterly Report on Form 10-Q.

Other Expenses

Interest Expense, net

Our interest expense, net remained flat when comparing the three and six months ended October 31, 2014 to the same periods in the prior fiscal year as interest expense associated with higher average debt balances in the three and six months ended October 31, 2014 was offset by interest savings associated with a reduction in the balance of our outstanding letters of credit.

Loss from Equity Method Investments

In the fiscal year ended April 30, 2014 (“fiscal year 2014”), we sold our 50% membership interest in US GreenFiber LLC and purchased the remaining 50% membership interest of Tompkins, both of which were previously accounted for using the equity method of accounting.

Prior to these transactions, we recorded income from equity method investments of $0.1 million in the three months ended October 31, 2013 and loss from equity method investments of $0.9 million in the six months ended October 31, 2013.

Provision for Income Taxes

Our provision for income taxes decreased $0.1 million during each of the three and six months ended October 31, 2014 as compared to the same periods in the prior fiscal year. The provisions for income taxes for the six months ended October 31, 2014 and October 31, 2013 include $0.4 million and $0.5 million deferred tax provisions due mainly to the increase in the deferred tax liability for indefinite lived assets and $0.1 million current tax provisions. 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.

43

Discontinued Operations

Discontinued operations in the three and six months ended October 31, 2013 related to the disposition of KTI BioFuels, Inc. (“BioFuels”). 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 is located in our Eastern region, to ReEnergy. We agreed to sell the BioFuels assets for undiscounted purchase consideration of $2.0 million, which will be paid to us in equal quarterly installments commencing November 1, 2013 and continuing over five years, subject to the terms of the purchase and sale agreement. We recognized a $0.4 million loss on disposal of discontinued operations in the first quarter of fiscal year 2014 associated with the disposition.

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

The following table provides details associated with the period-to-period changes in revenues (dollars in millions):

	Period-to-Period Change for the Three Months Ended October 31, 2014 vs. 2013						Period-to-Period Change for the Six Months Ended October 31, 2014 vs. 2013
Eastern Region	Amount			% of Growth			Amount			% of Growth

Closed landfills		(1.8	)		(4.5	)%		(2.7	)		(3.4	)%
Total solid waste operations	$	1.8			4.5	%	$	4.4			5.6	%

Price.

• The price change component in Eastern region quarterly solid waste revenues growth period-to-period is the result of $0.4 million from favorable collection pricing and $0.1 million from favorable disposal pricing related to landfills.

• The price change component in Eastern region year-to-date solid waste revenues growth period-to-period is the result of $0.6 million from favorable collection pricing.

Volume.

• The volume change component in quarterly Eastern region solid waste revenues growth period-to-period is the result of $0.8 million from higher disposal volumes (which includes a mix shift in volumes from landfills to transfer stations), $1.0 million from higher collection volumes and $0.1 million from higher processing volumes.

• The volume change component in year-to-date Eastern region solid waste revenues growth period-to-period is the result of $2.3 million from higher disposal volumes (which includes a mix shift in volumes from landfills to transfer stations), $1.7 million from higher collection volumes and $0.2 million from higher processing volumes.

Acquisitions and divestitures.

• The acquisitions and divestitures change component in quarterly and year-to-date Eastern region solid waste revenues growth period-to-period is the result of the acquisition of a solid waste hauling operation in September 2013 and a transfer station in November 2013.

Closed landfill.

• The closed landfill change component in quarterly and year-to-date total solid waste revenues growth period-to-period is the result of a landfill in the Eastern region that ceased operations in April 2014 in accordance with its permit.

Eastern region operating income remained flat and decreased $0.3 million during the three and six months ended October 31, 2014, respectively, as compared to the same periods in the prior fiscal year. The changes in operating income are largely attributable to the solid waste revenues growth discussed above combined with the following cost changes:

• Cost of operations: Cost of operations increased by $3.4 and $7.3 million period-to-period, resulting in margin erosion for both periods as costs increased at a greater rate than revenues. The changes were due primarily to an increase in third-party direct costs associated with higher collection and disposal volumes from organic customer growth and the acquisition of a transfer station, and an increase in other operational costs, including labor and related healthcare costs, and facility costs associated with hauling operations and certain landfills in our Eastern region.

• General and administration: General and administration expenses increased $0.3 million and $0.8 million period-to-period due primarily to an increase in bad debt expense in the three and six months ended October 31, 2014 associated with increased customer growth and bad debt recoveries in the three months ended October 31, 2013, and a charge accrued for a potential legal settlement with the MADEP. See discussion in Legal Proceedings included under Part II, Item 1 of this Quarterly Report on Form 10-Q.

• Depreciation and amortization: Depreciation and amortization costs increased $0.3 million and $0.7 million period-to-period due to an increase in landfill amortization associated with higher landfill volumes at our Southbridge landfill and a $0.3 million increase in estimated final capping costs at a closed landfill, and an increase in other amortization associated with acquired intangible assets.

• Other: Other charges impacting operating income period-to-period include an environmental remediation charge recorded in the three and six months ended October 31, 2014 associated with the environmental remediation at our Southbridge landfill.

45

Western Region

Our Western region revenues increased $1.8 million, or 3.1%, and $5.6 million, or 4.8%, during the three and six months ended October 31, 2014, respectively, as compared to the same periods in the prior fiscal year (dollars in millions).

	Period-to-Period Change for the Three Months Ended October 31, 2014 vs. 2013						Period-to-Period Change for the Six Months Ended October 31, 2014 vs. 2013
Western Region	Amount			% of Growth			Amount			% of Growth
Price	$	0.4			0.7	%	$	1.3			1.1	%
Volume		1.4			2.4	%		3.9			3.4	%
Commodity price & volume		(0.2	)		(0.3	)%		(0.4	)		(0.4	)%
Acquisitions & divestitures		0.2			0.3	%		0.8			0.7	%
Total solid waste operations	$	1.8			3.1	%	$	5.6			4.8	%

Price.

• The price change component in quarterly Western region solid waste revenues growth period-to-period is the result of $0.4 million from favorable collection pricing.

• The price change component in year-to-date Western region solid waste revenues growth period-to-period is the result of $1.2 million from favorable collection pricing and $0.1 million from favorable disposal pricing related primarily to transfer stations.

Volume.

• The volume change component in quarterly Western region solid waste revenues growth period-to-period is the result of $1.9 million from higher disposal volumes (of which $1.2 million relates to higher landfill volumes and $0.7 million relates to higher transfer station volumes associated with two new transfer station contracts), partially offset by $0.4 million from lower collection volumes and $0.1 million from lower processing volumes.

• The volume change component in year-to-date Western region solid waste revenues growth period-to-period is the result of $5.1 million from higher disposal volumes (of which $3.2 million relates to higher landfill volumes, $1.8 million relates to higher transfer station volumes associated with two new transfer station contracts, and $0.1 million relates to higher transportation volumes), partially offset by $1.0 million from lower collection volumes and $0.2 million from lower processing volumes.

Commodity price and volume.

• The commodity price and volume change component in quarterly and year-to-date Western region solid waste revenues growth period-to-period is the result of lower power generation and processing commodity volumes.

Acquisitions and divestitures.

• The quarterly and year-to-date acquisitions and divestitures change component in Western region solid waste revenues growth period-to-period is the result of various solid waste hauling operation acquisitions completed between August 2013 and September 2014.

46

Western region operating income increased $0.1 million and $1.0 million during the three and six months ended October 31, 2014, respectively, as compared to the same periods in the prior fiscal year. The changes in operating income are largely attributable to the solid waste revenues growth discussed above combined with the following cost changes:

• Cost of operations: Cost of operations increased by $3.0 million and $5.6 million period-to-period, resulting in margin erosion for both periods as costs increased at a greater rate than revenues. The changes were due to: an increase in third-party direct costs associated with higher hauling costs driven by organic transfer station volume growth (including the addition of two 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 Casella-Altela Regional Environmental Services, LLC (“CARES”) and lower collection volumes; an increase in labor and related benefit costs; an increase in direct operational costs including depletion of landfill operating lease obligations due to increased landfill volumes and an increase in host community fees and royalty fees; and an increase in repair and maintenance costs associated with our fleet and hauling operation facilities.

• General and administration: General and administration costs decreased by $0.7 million and $0.5 million period-to-period due to higher than normal bad debt expense in the same periods in the prior fiscal year due to collectability issues associated with two disposal customers.

• Depreciation and amortization: Depreciation and amortization costs remained flat and increased $0.8 million period-to-period due primarily to an increase in landfill amortization associated with higher landfill volumes at certain of our landfills in the Western region.

Recycling

Recycling revenues increased $1.8 million and $3.0 million during the three and six months ended October 31, 2014, respectively, as compared to the same periods in the prior fiscal year. The increases in recycling revenues period-to-period are primarily the result of higher commodity volumes, the acquisition of the remaining 50% membership interest of Tompkins, and favorable commodity pricing in the market during the three months ended October 31, 2014.

Recycling operating income increased by $0.5 million and $0.4 million during the three and six months ended October 31, 2014, respectively, as compared to the same periods in the prior fiscal year due to increased revenues and improved operating efficiencies, partially eroded by higher commodity purchased material costs and facility maintenance activities.

Other

Revenues increased $3.6 million and $8.8 million during the three and six months ended October 31, 2014, respectively, as compared to the same periods in the prior fiscal year largely 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.

Operating income remained flat and decreased by $0.9 million when comparing the three and six months ended October 31, 2014 to the same periods in the prior fiscal year as increased revenues were offset, or more than offset year-to-date, 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.

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 acquisitions, fixed asset purchases (including capital expenditures for vehicles), debt servicing, landfill development and cell construction, as well as site and cell closure. We generally meet liquidity needs from operating cash flows or from our senior secured revolving credit facility (“Revolver”).

Financing Activities

In the three months ended October 31, 2014, we completed a financing transaction involving $11.0 million 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 $5.5 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. We borrowed the additional proceeds of the New Hampshire Bonds to repay borrowings under our Revolver for qualifying property, plant and equipment assets purchased in New Hampshire since October 5, 2011.

47

In addition, on November 19, 2014, we announced an offering of $25.0 million aggregate principal amount of New York State Environmental Facilities Corporation Solid Waste Disposal Revenue Bonds Series 2014 (“New York Bonds”). An additional $15.0 million aggregate principal amount of New York Bonds may be offered under the same indenture in the future. There can be no assurance that this offering will be completed.

Outstanding Long-Term Debt

Senior Secured Revolving Credit Facility. The Revolver is a $227.5 million component of our senior revolving credit and letter of credit facility due March 18, 2016 (“Senior Credit Facility”). We have the right to request, at our discretion, an increase in the amount of the Senior Credit Facility by an aggregate amount of $100.0 million, subject to certain conditions set forth in the Senior Credit Facility agreement. The Senior Credit Facility is guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries.

As of October 31, 2014, we were in compliance with all financial covenants contained in the Senior Credit Facility as follows:

Other adjustments as allowed by senior credit facility agreement		7.9
Bank - defined cash flow metric	$	101.8

In addition to the financial covenants described above, the Senior Credit Facility, as amended, also contains a number of important customary affirmative and negative covenants which restrict, among other things, our ability to sell assets, pay dividends, invest in non-wholly owned entities, repurchase stock, incur debt, grant liens and issue preferred stock. As of

48

October 31, 2014, we were in compliance with all covenants under the credit agreement governing the Senior Credit Facility. 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.

Further advances were available under the Revolver in the amount of $56.1 million as of October 31, 2014. The available amount is net of outstanding irrevocable letters of credit totaling $27.1 million as of October 31, 2014, at which date no amount had been drawn.

We are planning to refinance the Senior Credit Facility before March 18, 2015, which is one year before the maturity date.

2019 Notes. As of October 31, 2014, we had outstanding $325.0 million aggregate principal amount of senior subordinated notes due February 15, 2019 (“2019 Notes”). The 2019 Notes accrue interest at the rate of 7.75% per annum. Interest is payable semiannually in arrears on February 15 and August 15 of each year.

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 October 31, 2014, 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.

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 Senior Credit Facility.

Maine Bonds. As of October 31, 2014, 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 guaranteed by certain of our 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. The FAME Bonds 2005R-2 mature on January 1, 2025.

As of October 31, 2014, 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. The FAME Bonds 2005R-1 mature on January 1, 2025.

Vermont Bonds. As of October 31, 2014, we had outstanding $16.0 million aggregate principal amount of Solid Waste Disposal Long-Term Revenue Bonds Series 2013 (“Vermont Bonds”). The Vermont Bonds, which are guaranteed by certain of our subsidiaries, accrue interest at 4.75% per annum through April 4, 2019, at which time they may be converted from a fixed rate to a variable rate. The Vermont Bonds mature on April 1, 2036.

New Hampshire Bonds. As of October 31, 2014, we had outstanding $11.0 million aggregate principal amount of New Hampshire Bonds. The New Hampshire Bonds, which are guaranteed by certain of our subsidiaries, accrue interest at 4.00% per annum through April 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.

Cash interest payments.

• Cash interest payments decreased $0.2 million from $17.6 million for the six months ended October 31, 2013 to $17.4 million for the six months ended October 31, 2014 based on a similar capitalization structure and the timing of payments.

Changes in assets and liabilities, net of effects from business acquisitions and divestitures.

• Our net cash flow provided by operating activities was unfavorably impacted $19.6 million in the six months ended October 31, 2014 by changes in our assets and liabilities. This was primarily associated with unfavorable impacts related to accounts receivable (which were affected by both increased revenues in October and a higher days sales outstanding), prepaid expenses, inventories and other assets (which were affected by the addition of a receivable, as well as the timing of payments and expense recognition), accounts payable (which were affected primarily by the timing of payments) and accrued expenses and other liabilities (which were affected primarily by cost changes, such as lower incentive compensation, and the timing of payments). This is compared to the six months ended October 31, 2013, when our net cash flow provided by operating activities was unfavorably impacted $12.0 million by changes in our assets and liabilities.

• This period-to-period decline in our changes in assets and liabilities, net of $7.6 million is due to the unfavorable $4.7 million 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 payroll costs, the unfavorable $2.0 million impact associated with the change in accounts payable based on the timing of payments, and the unfavorable $0.9 million impact associated with the change in accounts receivable based on increased revenues, a higher days sales outstanding, and reserving for two specific customers in the three months ended October 31, 2013.

Net cash used in investing activities. Cash flows used in investing activities increased by $3.1 million during the six months ended October 31, 2014 as compared to the same period in the prior fiscal year.

50

The most significant items affecting the change in our investing cash flows for the six months ended October 31, 2014 when compared to the same period in the prior fiscal year are summarized below:

• Capital expenditures. Capital expenditures were $8.2 million higher in the six months ended October 31, 2014 due primarily to increased spending on our fleet, various landfill development costs, and the installation of a landfill gas treatment system at our Juniper Ridge landfill.

• Payments related to investments. During the six months ended October 31, 2013, we made investments in unconsolidated entities totaling $2.1 million, whereas we made no investments in the six months ended October 31, 2014.

• Acquisitions, net of cash acquired. During the six months ended October 31, 2013, cash outflows associated with acquisitions totaled $2.8 million compared to $0.3 million in the six months ended October 31, 2014 based on the respective acquisition activity.

• Payments on landfill operating lease contracts. We made lower payments on landfill operating lease contracts of $1.0 million in the six months ended October 31, 2014 due primarily to the timing of payments associated with an operating lease at one of our Western region landfills.

Net cash provided by financing activities. Cash flows provided by financing activities increased $5.1 million during the six months ended October 31, 2014 as compared to the same period in the prior fiscal year.

The most significant items affecting the change in our financing cash flows for the six months ended October 31, 2014 when compared to the same period in the prior fiscal year are lower principal payments of $7.5 million, which more than offset the $2.5 million in lower debt borrowings.

Net cash provided by (used in) discontinued operations. Cash flows from discontinued operations increased $0.4 million during the six months ended October 31, 2014 as compared to the same period in the prior fiscal year. Cash flows from discontinued operations are associated with the business disposition of BioFuels in exchange for a $2.0 million note receivable, with quarterly payments commencing on this note effective November 1, 2013.

Hedging

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. In fiscal year 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 senior second lien notes (“Second Lien Notes”) effective January 15, 2013. The total notional amount of these agreements is $150.0 million and require us to receive interest based on changes in the London Interbank Offered Rate index and pay interest at a rate of approximately 1.40%. The agreements mature on March 15, 2016. During the fiscal year ended April 30, 2013 (“fiscal year 2013”), we dedesignated both of the $75.0 million forward starting interest rate derivative agreements and discontinued hedge accounting in accordance with 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 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. As of October 31, 2014, we are not party to any interest rate swaps designated as effective cash flow or fair value hedges.

We also use a variety of strategies to mitigate the impact of fluctuations in commodity prices including 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, resulting in a fixed price being received from these sales. As of October 31, 2014, we were not party to any commodity hedging agreements. For further discussion on commodity price volatility, see “Item 3 — Quantitative and Qualitative Disclosures about Market Risk — Commodity Price Volatility” below.

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 $250.0 million. Our ability and willingness to issue securities pursuant to this registration statement will depend on market conditions at the time of any such desired offering and therefore we may not be able to issue

51

such securities on favorable terms, if at all. As part of our planned refinancing of our Senior Credit Facility, we expect to replace this universal shelf registration statement with a new universal shelf registration statement registering an equal amount of securities. This replacement, if declared effective on a timetable that is consistent with our refinancing, will maximize our refinancing flexibility, including enabling us to do a registered offering of additional 2019 Notes. There can be no assurance that the registration statement would be declared effective, or that we are able to complete such a registered offering.

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 operations. 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. We have implemented a fuel and oil recovery fee, which is designed to recover escalating fuel price fluctuations above an expected floor. We therefore believe we should be able to implement price increases sufficient to 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.

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. In addition, particularly harsh weather conditions typically result in increased operating costs.

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 2005R-2, New Hampshire Bonds and Vermont Bonds, no beneficial holder of the 2019 Notes, FAME Bonds 2005R-2, New Hampshire Bonds and/or Vermont Bonds is permitted to knowingly acquire 2019 Notes, FAME Bonds 2005R-2, New Hampshire Bonds and/or Vermont Bonds if such person would own 10% or more of the consolidated debt for which relevant subsidiaries of

52

ours are obligated (and must dispose of 2019 Notes, FAME Bonds 2005R-2, New Hampshire 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 2005R-2, New Hampshire 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 October 31, 2014, that dollar amount was $51.8 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 year ended April 30, 2014.

Adoption of New Accounting Pronouncements

For a description of the new accounting standards adopted that may affect us, see Note 1 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

Interest Rate Volatility

We had interest rate risk relating to approximately $147.9 million of long-term debt at October 31, 2014. The weighted average interest rate on the variable rate portion of long-term debt was approximately 4.0% at October 31, 2014. Should the average interest rate on the variable rate portion of long-term debt change by 100 basis points, our quarterly interest expense would increase or decrease by $0.4 million.

The remainder of our long-term debt is at fixed rates and not subject to interest rate risk.

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 use a number of strategies to mitigate impacts from commodity price fluctuations, such as indexed purchases, floor prices, fixed price agreements, and revenue share arrangements. As of October 31, 2014, we were not party to any commodity hedge contracts. We do not use financial instruments for trading purposes and are not a party to any leveraged derivatives.

If commodity prices were to have changed by 10% on August 1, 2014, the impact on our operating income in the three months ended October 31, 2014 is estimated by management to have been approximately $0.4 million based on the observed impact of commodity price changes on operating income margin. Our sensitivity to changes in commodity prices is complex because each customer contract is unique relative to revenue sharing, tipping or processing fees and other arrangements. The above operating income impact may not be indicative of future operating results and actual results may vary materially.

ITEM 4. CONTROLS AND PROCEDURES

a) Evaluation of disclosure controls and procedures. Our management, with the participation of the chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of October 31, 2014. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the 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,

53

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 our management, including the 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 October 31, 2014, our chief executive officer and chief financial officer have 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 October 31, 2014 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

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 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 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 ASC 450-20.

New York Attorney General Matter

In July 2014, we entered into an Assurance of Discontinuance (“AOD”) with the office of the New York Attorney General (“NYAG”) in connection with our commercial practices in certain specified counties in New York. The AOD requires, among other things, that we modify our service contracts for two to ten yard containers with our commercial customers in the specified counties by shortening the initial term of such contracts to two years and providing for only one extension term of one year. We also agreed (i) to limit the liquidated damages to be paid by a customer, if a customer prematurely terminates its contract with us, to three months in year one of the contract and one month in year two or any extension year of the contract, (ii) to provide the NYAG with post-acquisition notice within thirty days of an acquisition of a provider of solid waste services with a value of $0.4 million or more and (iii) to pay the State of New York the sum of $0.1 million. We recorded a charge of $0.1 million, included in general and administration, in the first quarter of the Transition Period. The counties in New York covered by the AOD are Allegany, Cattaraugus, Chautauqua, Chemung, Clinton, Franklin, Schuyler, St. Lawrence, Steuben, and Tompkins. This matter is now closed other than with respect to ongoing compliance.

54

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. The Draft Order seeks a civil administrative cash penalty of less than $0.1 million and an additional administrative penalty in the form of a Supplemental Environmental Project in the amount of $0.2 million. We are working with the MADEP to address these allegations to arrive at an appropriate resolution thereof. It is probable that we will incur a loss with respect to this matter and as a result we recorded a charge of approximately $0.2 million in general and administration in the six months ended October 31, 2014.

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 represent our potential or outstanding material claims.

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. It is unlike that any significant costs relating to onsite remediation will be incurred until the fiscal year ending December 31, 2016. WSI and NiMo are jointly and severally liable for the total cost to remediate.

In September 2011, the DEC settled its environmental claim against the estate of the former GM (known as “Motors Liquidation Trust”) for future remediation costs relating to the WSI site for face value of $3.0 million. In addition, in November 2011 we settled our own claim against the Motors Liquidation Trust for face value of $0.1 million. These claims will be paid by GM in warrants to obtain stock of the reorganized GM. GM has issued the warrants to us beginning in May 2013 and at this time there is no way to accurately estimate when the remainder of these claims will be paid. We have not assumed that any future proceeds from the sale of securities received in payment of these claims will reduce our exposure.

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. Our expenditure could be significantly higher if costs exceed estimates. We inflate the estimated costs in current dollars until the expected time of payment and discount the total cost to present value using a risk free interest rate of 2.0%. The changes to the environmental remediation liability associated with the Potsdam environmental remediation liability for the six months ended October 31, 2014 and 2013 are as follows:

	Six Months Ended October 31,
	2014			2013
Beginning balance	$	5.3		$	5.3
Obligations incurred		—			—
Accretion expense		0.1			0.1

Southbridge Landfill Environmental Remediation Liability

On or about August 24, 2013, we experienced the movement of stockpiled earth at our Southbridge landfill in Southbridge, Massachusetts. The stockpiled materials consisted of soil removed and relocated to create space for the construction of additional landfill airspace at our Southbridge landfill. The earth had been relocated and stored during the fall, winter and spring construction season of fiscal year 2013.

The movement caused some of the stockpiled earth to enter wetlands on property owned by us. On or about August 29, 2013, we notified the MADEP, and the Towns of Southbridge and Charlton, Massachusetts, of the occurrence of the movement. On or about September 6, 2013, MADEP issued a “Unilateral Administrative Order” (“UAO”) requiring us to provide MADEP with a plan to remove any materials deposited in the wetlands as a result of the movement (“Plan”). On or about October 3, 2013, we submitted the Plan to MADEP, and on or about October 15, 2013, MADEP approved the Plan and verbally issued permission for us to implement the Plan. We have implemented the Plan under the supervision of MADEP.

In January 2014, we received correspondence from the Massachusetts’ Office of the Attorney General (“MAAG”), advising us that the MAAG intended to schedule a meeting with us to discuss this incident, and to possibly file suit against us for violation of the Massachusetts Wetlands Protection, Clean Air and Solid Waste Acts. We met with the MAAG in March 2014 and again in July 2014 to discuss our ongoing remediation effort, and the parties are continuing to have discussions regarding the resolution of this matter.

On or about April 25, 2014, we notified MADEP and other interested parties that areas of sloughing had occurred in a plateau created as part of new cell construction at our Southbridge landfill. Some of the same contractors and technical advisors that were involved in the initial movement of stockpiled earth are also involved in the new cell construction that includes this area of sloughing. We repaired the areas of sloughing on April 25, 2014 and no damage occurred in the abutting wetlands. On May 9, 2014, MADEP issued a UAO directing us to ensure that the areas of sloughing at the plateau were repaired and to take steps to ensure that there would be no incursion into the wetlands, and requiring that we undertake corrective actions to ensure the stability of the plateau. Prior to MADEP’s issuance of the latest UAO, we were in the process of awarding a contract to a soil remediation company to undertake corrective actions and ensure stability at the plateau. This contract was awarded, and the work was finished in September 2014.

We anticipate that the execution of the Plan and related matters will involve remediation costs of approximately $3.0 million and that such costs could be higher if actual costs exceed estimates. We have provided our insurer with notice of the Plan, and the costs expended by us to date to comply with the Plan. We have also provided notice to certain of our contractors and technical advisors that the movement has occurred, that significant remediation costs will be incurred in executing the Plan and related matters, and that we expect our contractor and technical advisor to assist in the execution of the Plan and related matters, to share in the remediation costs thereof as responsible parties, and to provide notice to their own insurers. We are currently engaged in discussion with our contractor and technical advisor regarding resolution of these matters. We believe that a loss in the range of $0.9 million to $3.0 million, including the resolution of our discussions with the MAAG, after taking into account amounts we expect to be reimbursed by our insurer and third-parties, is probable and have therefore recorded a charge of $0.4 million in the three months ended October 31, 2014. We had previously recorded a charge of $0.4 million in fiscal year 2014 and a charge of approximately $0.1 million in the first quarter of the Transition Period as an environmental remediation charge.

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 year ended April 30, 2014, that could have a material effect on our business, results of operations, financial condition and/or liquidity and that could cause our operating results to vary significantly from period to period. As

56

of October 31, 2014, there have been no material changes to the risk factors disclosed in our Annual Report on Form 10-K for the year ended April 30, 2014, except as set forth in the following paragraph. We may disclose additional changes to our risk factors or disclose additional factors from time to time in our future filings with the SEC.

Our Senior Credit Facility matures on March 18, 2016 and there can be no assurance that we can refinance it prior to March 18, 2015.

Our Senior Credit Facility matures on March 18, 2016. If we do not refinance the Senior Credit Facility prior to one year before its maturity date, the full amount of the Senior Credit Facility will become a current liability on our balance sheet. In such an event, it is possible that our auditors could express a going concern opinion in their audit of our financial statements for the year ending December 31, 2015 if we are unable to complete a refinancing prior to such date. Work is underway to complete the refinancing prior to March 18, 2015. However, the completion of a refinancing on a timely basis is subject to market and other conditions, and there is no assurance that we will complete it on favorable terms.

(“Parent”), 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 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 our 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 customer accounts, discontinued operations and earnings from equity method investees are included in our Other segment.

The consolidated financial statements as of October 31, 2014 and for the three and six months ended October 31, 2014 and 2013 are unaudited. The accompanying consolidated financial statements, which include the accounts of the Parent, our wholly-owned subsidiaries and certain 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 applicable. Assets and liabilities of discontinued operations and assets held-for-sale are segregated from those of continuing operations and reported in separate captions in the balance sheet, as applicable. The results of operations that have been disposed of or classified as held-for-sale and qualify for discontinued operations accounting are reported in discontinued operations, as applicable. Our significant accounting policies are more fully discussed in Item 8 of our Annual Report on Form 10-K for the year ended April 30, 2014, which was filed with the SEC on June 26, 2014.

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 October 31, 2014 may not be indicative of the results for any other interim period or the eight-month transition period described below. 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 year ended April 30, 2014.

We consider events or transactions that have occurred after the consolidated balance sheet date of October 31, 2014, but prior to the filing of the consolidated financial statements with the SEC on this Quarterly Report on Form 10-Q. We have evaluated subsequent events through the filing date of this Quarterly Report on Form 10-Q with the SEC.

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 will become effective for our fiscal year beginning January 1, 2015 and ending December 31, 2015. We intend to file a Transition Report on Form 10-KT for the eight-month transition period ending December 31, 2014 (“Transition Period”). This Quarterly Report on Form 10-Q for the three and six month periods ended October 31, 2014 is for the second quarter of the Transition Period.

New Accounting Pronouncements Pending Adoption

Revenue Recognition

In May 2014, the Financial Accounting Standards Board (“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 that reporting period, beginning after December 15, 2016 under either full or modified retrospective adoption. Early application is not permitted. We are currently assessing the potential impact of these changes to our consolidated financial statements as a result of adopting this standard.

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 or a group of components of an entity is required to be reported in discontinued operations once the component of an entity 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 that reporting period, beginning after December 15, 2014, with early adoption permitted, but only for disposals, or classifications as held for sale, that have not been reported in financial statements previously issued or available for issuance. Adoption of this standard may impact the presentation of, and disclosures in, our consolidated financial statements and notes thereto.

Adoption of New Accounting Pronouncements

Income Taxes

In July 2013, the FASB issued an accounting standards update for the reporting of an unrecognized tax benefit, or portion thereof, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The update provides an exception, requiring the unrecognized tax benefit to be presented in the financial statements as a liability when the carryforward is not available at the reporting date under the tax laws to settle additional income taxes that would result in the disallowance of a tax provision or the tax laws do not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose. This guidance is effective prospectively, with retrospective application permitted, for annual reporting periods, and interim reporting periods within that reporting period, beginning after December 15, 2013, with early adoption permitted. We adopted this guidance effective May 1, 2014 and it has not had, and we believe will not have, a material impact on our consolidated financial statements.

Accounting Policies [Abstract]

New Accounting Policies Adopted and Pending Adoption

New Accounting Pronouncements Pending Adoption

Revenue Recognition

In May 2014, the Financial Accounting Standards Board (“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 that reporting period, beginning after December 15, 2016 under either full or modified retrospective adoption. Early application is not permitted. We are currently assessing the potential impact of these changes to our consolidated financial statements as a result of adopting this standard.

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 or a group of components of an entity is required to be reported in discontinued operations once the component of an entity 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 that reporting period, beginning after December 15, 2014, with early adoption permitted, but only for disposals, or classifications as held for sale, that have not been reported in financial statements previously issued or available for issuance. Adoption of this standard may impact the presentation of, and disclosures in, our consolidated financial statements and notes thereto.

Adoption of New Accounting Pronouncements

Income Taxes

In July 2013, the FASB issued an accounting standards update for the reporting of an unrecognized tax benefit, or portion thereof, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The update provides an exception, requiring the unrecognized tax benefit to be presented in the financial statements as a liability when the carryforward is not available at the reporting date under the tax laws to settle additional income taxes that would result in the disallowance of a tax provision or the tax laws do not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose. This guidance is effective prospectively, with retrospective application permitted, for annual reporting periods, and interim reporting periods within that reporting period, beginning after December 15, 2013, with early adoption permitted. We adopted this guidance effective May 1, 2014 and it has not had, and we believe will not have, a material impact on our consolidated financial statements.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

9. 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 include cash and cash equivalents, restricted cash, trade receivables, restricted trust and escrow accounts held in trusts with various banks as collateral for our obligations relative to landfill final capping, closure and post-closure costs, interest rate derivatives, trade payables and long-term debt. The carrying values of cash and cash equivalents, restricted cash, trade receivables and trade payables approximate their respective fair values due to their short-term nature. The fair value of the restricted trust and escrow accounts are included as restricted assets in the Level 1 tier below. The fair values of the interest rate derivatives, included in the Level 2 tier below, are calculated based on the three month LIBOR yield curve that is observable at commonly quoted intervals for the full term of the interest rate swaps, adjusted by the credit risk of us and our counter-parties based on observable credit default swap rates. We recognize all derivatives on the balance sheet at fair value.

As of October 31, 2014 our assets and liabilities measured at fair value on a recurring basis included the following:

	Fair Value Measurement at October 31, 2014 Using:
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Assets:
Restricted assets	$	790	$	—	$	—
Liabilities:
Interest rate derivatives	$	—	$	2,177	$	—

As of April 30, 2014 our assets and liabilities measured at fair value on a recurring basis included the following:

	Fair Value Measurement at April 30, 2014 Using:
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Assets:
Restricted assets	$	681	$	—	$	—
Liabilities:
Interest rate derivatives	$	—	$	2,770	$	—

Fair Value of Debt

As of October 31, 2014, the fair value of our fixed rate debt, including our 7.75% senior subordinated notes due 2019 (“2019 Notes”), the Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-2 (“FAME Bonds 2005R-2”), the Vermont Economic Development Authority Solid Waste Disposal Long Term Revenue Bonds Series 2013 (“Vermont Bonds”), and the New Hampshire Bonds was approximately $382,460 and the carrying value was $373,400. The fair value of the 2019 Notes is 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 Vermont 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 that utilizes pricing models and pricing systems, mathematical tools and judgment to determine the evaluated price for the security based on the market information of each of the bonds or securities with similar characteristics. As of October 31, 2014, the fair value of our Revolver is considered to be Level 2 within the fair value hierarchy as its fair value approximated its carrying value of $144,300 based on current borrowing rates for similar types of borrowing arrangements.

4. ACCRUED 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.

Discontinued Operations and Disposal Groups [Abstract]

Divestiture Transactions and Discontinued Operations

11. 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. The review consists of evaluating whether the business qualifies as a component of an entity for which the operations and cash flows are clearly distinguishable; whether it is anticipated that the cash flows of the component have been or will be eliminated from ongoing operations after the disposal transaction and by the end of the assessment period; and whether we will have any significant continuing involvement in the operations of the component after the disposal transaction. Planned business dispositions are presented as discontinued operations when all three criteria are met. Additionally, 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.

Businesses that qualify as held-for-sale are carried at the lower of their carrying value or fair value less costs to sell in the period the held-for-sale criteria are met. For a business that is classified as held-for-sale and meets the discontinued operations criteria, all initial or subsequent adjustments to the carrying value of the component are classified in discontinued operations.

Discontinued Operations

In fiscal year 2013, we initiated a plan to dispose of KTI BioFuels, Inc. (“BioFuels”), a construction and demolition material processing facility located in Lewiston, Maine, 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 is being 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 is recorded in current and non-current assets of discontinued operations in the consolidated balance sheets. We recognized a $378 loss on disposal of discontinued operations in the first quarter of 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) income before income taxes attributable to discontinued operations for the three and six months ended October 31, 2014 and 2013, respectively, are as follows:

	Three Months Ended October 31,					Six Months Ended October 31,
	2014		2013			2014		2013
Revenues	$	—	$	5		$	—	$	3,316
(Loss) income before income taxes	$	—	$	(45	)	$	—	$	284

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

Divestiture Transactions

In the first quarter of fiscal year 2013, we executed a purchase and sale agreement (“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 is being paid to us in equal 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 are nearly complete with site remediation under the auspices and in accordance with work plans approved by the Maine Department of Environmental Protection (“MEDEP”), and the U.S. Environmental Protection Agency (“USEPA”). The time for completion of this project has been consensually extended by us and the City of Biddeford, and we expect to complete this project and transfer ownership of the real property to the City of Biddeford by, or before, spring 2015. Based on incurred costs to date and estimates regarding the remaining costs to fulfill our obligation under the Agreement, a potential gain on divestiture of up to $1,000 is possible.

Stockholders' Equity

7. STOCKHOLDERS’ EQUITY

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 other similar events), plus (ii) such additional number of shares of Class A common stock as are currently subject to options granted under our 1993 Incentive Stock Option Plan, 1994 Non-statutory Stock Option Plan, 1996 Option Plan, and 1997 Stock Option Plan (“Prior Plans”), which are not actually issued under the Prior Plans because such options expire or otherwise result in shares not being issued. As of October 31, 2014, there were 994 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.

Stock Options

Options 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, options granted have a term not to exceed ten years and vest over a one to four year period from the date of grant.

A summary of stock option activity for the six months ended October 31, 2014 is as follows:

	Stock Options			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (years)		Aggregate Intrinsic Value
Outstanding, April 30, 2014		1,368		$	8.65
Granted		200		$	4.86
Exercised		(33	)	$	4.30
Forfeited		(145	)	$	13.06

Exercisable, October 31, 2014		849		$	9.73		3.2	$	139
Expected to vest, October 31, 2014		1,389		$	7.76		5.4	$	248

Stock-based compensation expense for stock options was $165 and $275 during the three and six months ended October 31, 2014, respectively, as compared to $88 and $203 during the three and six months ended October 31, 2013.

As of October 31, 2014, total unrecognized stock-based compensation expense related to outstanding stock options was $1,200, which will be recognized over a weighted average period of 1.8 years.

Our calculations of stock-based compensation expense associated with stock options granted in the three and six months ended October 31, 2014 were made using the Black-Scholes valuation model. The fair value of stock options grants were estimated assuming no expected dividend yield using the following weighted average assumptions for the three and six months ended October 31, 2014 (no stock options granted in the three and six months ended October 31, 2013):

	Three Months Ended October 31, 2014			Six Months Ended October 31, 2014
Stock Options:
Expected life		7.13 years			7.00 years
Risk-free interest rate		2.15	%		2.15	%
Expected volatility		82.08	%		82.75	%

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.

Other Stock Awards

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 on the third fiscal year-end following the grant date and are based on our attainment of a targeted average return on net assets as of the vesting date.

A summary of restricted stock, restricted stock unit and performance stock unit activity for the six months ended October 31, 2014 is as follows:

	Restricted Stock, Restricted Stock Units, and Performance Stock Units (1)			Weighted Average Grant Price		Weighted Average Remaining Contractual Term (years)		Aggregate Intrinsic Value
Outstanding, April 30, 2014		1,077		$	4.77
Granted		370		$	4.91
Class A Common Stock Vested		(363	)	$	4.89
Forfeited		(32	)	$	4.39
Outstanding, October 31, 2014		1,052		$	4.79		1.7	$	191
Expected to vest, October 31, 2014		927		$	4.40		1.6	$	173

(1) Performance stock units are included at the 100% attainment level. Attainment of maximum annual returns on net assets could result in the issuance of an additional 251 shares of Class A common stock.

During the six months ended October 31, 2014, we awarded certain employees restricted stock units, which vest incrementally over a three year period beginning on the first anniversary of the date of grant and are based on continued employment.

Stock-based compensation expense related to restricted stock, restricted stock units and performance stock units was $465 and $897 during the three and six months ended October 31, 2014, respectively, as compared to $475 and $966 during the three and six months ended October 31, 2013.

As of October 31, 2014, total unrecognized compensation expense related to outstanding restricted stock and restricted stock units was $2,685, which will be recognized over a weighted average period of 1.9 years. Maximum unrecognized stock-based compensation expense at October 31, 2014 related to outstanding performance stock units, and subject to the attainment of targeted maximum annual returns on net assets, was $2,479 to be recognized over a weighted average period of 0.5 years. We do not expect to recognize any compensation expense as of October 31, 2014 related to outstanding performance stock units based on our expected attainment levels.

We also recorded $16 and $37 of stock-based compensation expense related to our Employee Stock Purchase Plan during the three and six months ended October 31, 2014, respectively, as compared to $15 and $39 during the three and six months ended October 31, 2013.

Accumulated Other Comprehensive Income

The change in the balance of accumulated other comprehensive income, which is included as a component of our stockholders’ deficit, for the six months ended October 31, 2014 is as follows:

	Marketable Securities

6. 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 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 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 ASC 450-20.

New York Attorney General Matter

In July 2014, we entered into an Assurance of Discontinuance (“AOD”) with the office of the New York Attorney General (“NYAG”) in connection with our commercial practices in certain specified counties in New York. The AOD requires, among other things, that we modify our service contracts for two to ten yard containers with our commercial customers in the specified counties by shortening the initial term of such contracts to two years and providing for only one extension term of one year. We also agreed (i) to limit the liquidated damages to be paid by a customer, if a customer prematurely terminates its contract with us, to three months in year one of the contract and one month in year two or any extension year of the contract, (ii) to provide the NYAG with post-acquisition notice within thirty days of an acquisition of a provider of solid waste services with a value of $350 or more and (iii) to pay the State of New York the sum of $100. We recorded a charge of $100, included in general and administration, in the first quarter of the Transition Period. The counties in New York covered by the AOD are Allegany, Cattaraugus, Chautauqua, Chemung, Clinton, Franklin, Schuyler, St. Lawrence, Steuben, and Tompkins. This matter is now closed other than with respect to ongoing compliance.

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. The Draft Order seeks a civil administrative cash penalty of $67 and an additional administrative penalty in the form of a Supplemental Environmental Project in the amount of $201. We are working with the MADEP to address these allegations to arrive at an appropriate resolution thereof. It is probable that we will incur a loss with respect to this matter and as a result we recorded a charge of $172 in general and administration in the six months ended October 31, 2014.

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 represent our potential or outstanding material claims.

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. It is unlikely that any significant costs relating to onsite remediation will be incurred until the fiscal year ending December 31, 2016. WSI and NiMo are jointly and severally liable for the total cost to remediate.

In September 2011, the DEC settled its environmental claim against the estate of the former GM (known as “Motors Liquidation Trust”) for future remediation costs relating to the WSI site for face value of $3,000. In addition, in November 2011 we settled our own claim against the Motors Liquidation Trust for face value of $100. These claims will be paid by GM in warrants to obtain stock of the reorganized GM. GM has issued warrants to us beginning in May 2013 and at this time there is no way to accurately estimate when the remainder of these claims will be paid. We have not assumed that any future proceeds from the sale of securities received in payment of these claims will reduce our exposure.

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. Our expenditures could be significantly higher if costs exceed estimates. We inflate the estimated costs in current dollars until the expected time of payment and discount the total cost to present value using a risk free interest rate of 2.0%. The changes to the environmental remediation liability associated with the Potsdam environmental remediation liability for the six months ended October 31, 2014 and 2013 are as follows:

	Six Months Ended October 31,
	2014			2013
Beginning balance	$	5,320		$	5,297
Obligations incurred		—			31
Accretion expense		69			69

Ending balance	$	5,119		$	5,397

Southbridge Landfill Environmental Remediation Liability

On or about August 24, 2013, we experienced the movement of stockpiled earth at our Southbridge landfill in Southbridge, Massachusetts. The stockpiled materials consisted of soil removed and relocated to create space for the construction of additional landfill airspace at our Southbridge landfill. The earth had been relocated and stored during the fall, winter and spring construction season of the fiscal year ended April 30, 2013 (“fiscal year 2013”).

The movement caused some of the stockpiled earth to enter wetlands on property owned by us. On or about August 29, 2013, we notified the MADEP, and the Towns of Southbridge and Charlton, Massachusetts, of the occurrence of the movement. On or about September 6, 2013, MADEP issued a “Unilateral Administrative Order” (“UAO”) requiring us to provide MADEP with a plan to remove any materials deposited in the wetlands as a result of the movement (“Plan”). On or about October 3, 2013, we submitted the Plan to MADEP, and on or about October 15, 2013, MADEP approved the Plan and verbally issued permission for us to implement the Plan. We have implemented the Plan under the supervision of MADEP.

In January 2014, we received correspondence from the Massachusetts’ Office of the Attorney General (“MAAG”), advising us that the MAAG intended to schedule a meeting with us to discuss this incident, and to possibly file suit against us for violation of the Massachusetts Wetlands Protection, Clean Air and Solid Waste Acts. We met with the MAAG in March 2014 and again in July 2014 to discuss our ongoing remediation effort, and the parties are continuing to have discussions regarding the resolution of this matter.

On or about April 25, 2014, we notified MADEP and other interested parties that areas of sloughing had occurred in a plateau created as part of new cell construction at our Southbridge landfill. Some of the same contractors and technical advisors that were involved in the initial movement of stockpiled earth are also involved in the new cell construction that includes this area of sloughing. We repaired the areas of sloughing on April 25, 2014 and no damage occurred in the abutting wetlands. On May 9, 2014, MADEP issued a UAO directing us to ensure that the areas of sloughing at the plateau were repaired and to take steps to ensure that there would be no incursion into the wetlands, and requiring that we undertake corrective actions to ensure the stability of the plateau. Prior to MADEP’s issuance of the latest UAO, we were in the process of awarding a contract to a soil remediation company to undertake corrective actions and ensure stability at the plateau. This contract was awarded, and the work was finished in September 2014.

We anticipate that the execution of the Plan and related matters will involve remediation costs of approximately $2,997 and that such costs could be higher if actual costs exceed estimates. We have provided our insurer with notice of the Plan, and the costs expended by us to date to comply with the Plan. We have also provided notice to certain of our contractors and technical advisors that the movement has occurred, that significant remediation costs will be incurred in executing the Plan and related matters, and that we expect our contractor and technical advisor to assist in the execution of the Plan and related matters, to share in the remediation costs thereof as responsible parties, and to provide notice to their own insurers. We are currently engaged in discussion with our contractor and technical advisor regarding resolution of these matters. We believe that a loss in the range of $850 to $2,997, including the resolution of our discussions with the MAAG, after taking into account amounts we expect to be reimbursed by our insurer and third-parties, is probable and have therefore recorded a charge of $375 in the three months ended October 31, 2014. We had previously recorded a charge of $400 in the fiscal year ended April 30, 2014 (“fiscal year 2014”) and a charge of $75 in the first quarter of the Transition Period as an environmental remediation charge.

2. BUSINESS COMBINATIONS

During the six months ended October 31, 2014, we acquired one solid waste hauling operation in each of the Eastern and Western regions, whereas, during the six months ended October 31, 2013, we acquired three solid waste hauling operations, two of which are located in the Western region and one of which is located in the Eastern region, and an industrial service management business (included in the Other segment). The operating results of these businesses are included in the accompanying 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. Intangible assets other than goodwill that are subject to amortization include acquired client lists and non-compete agreements, which are often negotiated as a part of our business combinations. These are amortized over a five to ten year period from the date of acquisition. Amounts recorded to goodwill are in most cases expected to be deductible for tax purposes.

The purchase price paid for these acquisitions during the six months ended October 31, 2014 and 2013 and the allocation of the purchase price is as follows:

	Six Months Ended October 31,
	2014		2013
Purchase Price:

Fair value of assets acquired and liabilities assumed		350		2,322
Excess purchase price to be allocated to goodwill	$	31	$	2,272

The following unaudited pro forma combined information shows the results of our continuing operations for the three and six months ended October 31, 2014 and 2013 as though each of the acquisitions completed in the six months ended October 31, 2014 and the twelve months ended April 30, 2014 had occurred as of May 1, 2013.

The pro forma results set forth in the table above have been prepared for comparative purposes only and are not necessarily indicative of the actual results of operations had the acquisitions occurred as of May 1, 2013 or the results of our future operations. Furthermore, the pro forma results do not give effect to all cost savings or incremental costs that may occur as a result of the integration and consolidation of the completed acquisitions.

Segment Reporting

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. Revenues associated with our solid waste operations are derived mainly from collection, transfer, disposal, landfill, landfill gas-to-energy 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 customer accounts, discontinued operations, and earnings from equity method investees are included in our Other segment.
