1. BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements include the accounts of Casella Waste Systems, Inc. (the “Parent”), its wholly-owned subsidiaries and an entity in which it has a controlling financial interest (collectively, “we”, “us” or “our”). For the consolidated subsidiary that is less than wholly-owned, the third-party holding of equity interest is referred to as a noncontrolling interest. The portion of net loss attributable to the noncontrolling interest holder of this subsidiary is presented as net loss attributable to noncontrolling interest in the unaudited consolidated statements of operations and the portion of comprehensive loss attributable to the noncontrolling interest holder of this subsidiary is presented as comprehensive loss attributable to noncontrolling interest in the unaudited consolidated statements of comprehensive loss. The portion of stockholders’ equity of this subsidiary attributable to the noncontrolling interest holder is presented as noncontrolling interest in the unaudited consolidated balance sheets and the unaudited consolidated statement of stockholders’ equity.

We are a regional, vertically-integrated solid waste services company that provides collection, transfer, disposal, landfill, landfill gas-to-energy, recycling and organics services in the northeastern United States. We market recyclable metals, aluminum, plastics, paper and corrugated cardboard, which have been processed at our recycling facilities, as well as recyclables purchased from third parties. We manage our solid waste operations on a geographic basis through two regional operating segments, the Eastern and Western regions, each of which includes a full range of solid waste services, and our larger-scale recycling and commodity brokerage operations through our Recycling segment. Ancillary operations, major customer accounts, discontinued operations and earnings through equity method investees are included in our Other segment.

The consolidated financial statements as of January 31, 2013 and for the three and nine months ended January 31, 2013 and 2012 are unaudited. These unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) and in the opinion of management, 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 nine months ended January 31, 2013 may not be indicative of the results that may be expected for any other interim period or the fiscal year ending April 30, 2013. The unaudited 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, 2012, which was filed with the SEC on June 28, 2012.

The preparation of our unaudited consolidated 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 at the date of the unaudited consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. 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, 2012.

Certain reclassifications have been made to previously reported amounts. These reclassifications had no effect on the previously reported consolidated financial position, results of operations or retained earnings.

10

We consider events or transactions that have occurred after the unaudited consolidated balance sheet date of January 31, 2013, but prior to the filing of the unaudited consolidated financial statements with the SEC on this Form 10-Q. We have evaluated subsequent events through the date of the filing of this Quarterly Report on Form 10-Q with the SEC.

Adoption of New Accounting Pronouncements

Comprehensive Income

In June 2011, the Financial Accounting Standards Board (the “FASB”) issued an accounting standards update for the presentation of comprehensive income. This guidance requires the presentation of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The updated standard also requires presentation of adjustments for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented. The FASB deferred certain portions of the accounting standard update related to presentation of reclassification adjustments from other comprehensive income to net income. This guidance, except for the deferred portion noted above, is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 with early adoption permitted. We adopted this guidance effective May 1, 2012. It only impacts the presentation of our financial statements and does not impact our consolidated financial position or results of operations.

New Accounting Pronouncements Pending Adoption

Comprehensive Income

In February 2013, the FASB issued an accounting standards update for the reporting of reclassifications out of accumulated other comprehensive income. This guidance requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under generally accepted accounting principles in the United States (“GAAP”) to be reclassified in its entirety to net income. For other amounts not required under GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under GAAP that provide additional detail about those amounts. This guidance is effective prospectively for annual and interim reporting periods beginning after December 15, 2012 and it will only impact the presentation of our financial statements or require additional disclosure and will not impact our consolidated financial position or results of operations.

Indefinite-Lived Intangible Assets Impairment Test

In July 2012, the FASB issued an accounting standards update on indefinite-lived intangible assets impairment testing. This guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the quantitative impairment test. If after assessing the totality of events or circumstances, we determine that it is not more likely than not that an indefinite-lived intangible asset is impaired, then we will not need to perform the quantitative impairment test in accordance with Accounting Standards Codification (“ASC”) 350-30. This guidance is effective for annual and interim indefinite-lived assets impairment tests performed for fiscal years beginning after September 15, 2012 with early adoption permitted, and we expect that it will have no impact on our consolidated financial position or results of operations.

Disclosures About Offsetting Assets and Liabilities

In December 2011, the FASB issued an accounting standards update regarding the disclosure of offsetting assets and liabilities in financial statements. This guidance requires an entity to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The objective of this disclosure is to facilitate comparison between those entities that prepare their financial statements on the basis of GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards. In January 2013, the FASB issued an accounting standards update to address implementation issues about the December 2011 accounting standards update by clarifying the scope of the offsetting disclosures. This guidance is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods, and it will only impact the presentation of our financial statements or require additional disclosure and will not impact our consolidated financial position or results of operations.

2. BUSINESS ACQUISITIONS

During the nine months ended January 31, 2013, we acquired four solid waste hauling operations in the Western region for total consideration of $5,384, including $4,854 in cash and $530 in holdbacks to the sellers, and all of the outstanding capital stock of Bestway Disposal Services and BBI Waste Services (“BBI”) in the Eastern region for total consideration, subject to certain closing adjustments based on the terms of the agreement, of $22,650, including $20,000 in cash and 625 shares of our Class A common stock, valued at an aggregate of $2,650. We recorded an additional $5,242 to goodwill for the increased deferred tax liability related to the BBI acquisition based on the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for income tax purposes, see Note 10 for further discussion. The acquisition of BBI, a provider of solid waste collection, transfer and liquid waste services in New Hampshire and Maine, on December 6, 2012 provides us the opportunity to internalize additional waste and recyclables and to consolidate operations, routes and transportation within the Eastern region. Revenue generated from BBI amounted to $2,924 from December 6, 2012 to January 31, 2013. During the nine months ended January 31, 2012, we acquired five solid waste hauling operations and completed the acquisition of the McKean County landfill business in Pennsylvania, by acquiring additional equipment not included in the original acquisition, for total consideration of $2,284, including $2,102 in cash and $182 in holdbacks to the sellers.

The operating results of these businesses are included in the accompanying unaudited consolidated statements of operations from the dates of acquisition, and the purchase prices have been allocated to the net assets acquired based on fair values at the dates of acquisition, with the residual amounts recorded as goodwill. Acquired intangible assets other than goodwill that are subject to amortization include client lists and non-compete covenants. These are amortized over a five to ten year period from the date of acquisition. All amounts recorded to goodwill are expected to be deductible for tax purposes, except for $8,078 of the current year goodwill related to the BBI acquisition. The purchase price allocated to net assets acquired and the residual amount allocated to goodwill during the nine months ended January 31, 2013 and 2012 are as follows:

	January 31,
	2013 (1)			2012
Equipment	$	9,403		$	605
Goodwill		14,575			569
Intangible assets		9,601			1,136
Current assets		1,475			—
Current liabilities		(7,118	)		(26	)
Total	$	27,936		$	2,284

1) The purchase price allocated to net assets acquired and the residual amount allocated to goodwill associated with the BBI acquisition has not been finalized and is provisional in nature. Management’s estimates and assumptions are subject to change upon finalization of the valuation and may be adjusted in accordance with ASC 805.

The following unaudited pro forma combined financial information shows the results of our operations for the three and nine months ended January 31, 2013 and 2012 as though each of the acquisitions made in the nine months ended January 31, 2013 and the twelve months ended April 30, 2012 had occurred as of May 1, 2011.

3. GOODWILL AND INTANGIBLE ASSETS

The following table shows the activity and balances related to goodwill from April 30, 2012 through January 31, 2013:

	April 30, 2012		Acquisitions		January 31, 2013
Eastern region	$	58	$	13,339	$	13,397

Total	$	101,706	$	14,575	$	116,281

Intangible assets as of January 31, 2013 and April 30, 2012 consist of the following:

	Covenants Not to Compete			Client Lists			Total
Balance, January 31, 2013
Intangible assets	$	17,022		$	11,432		$	28,454

4. ACCRUED CAPPING, CLOSURE AND POST CLOSURE

Accrued capping, closure and post-closure costs include the current and non-current portion of costs associated with obligations for closure and post-closure of our landfills. We estimate our future capping, closure and post-closure costs in order to determine the 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 capping, closure and post-closure liabilities for the nine months ended January 31, 2013 and 2012 are as follows:

	Nine Months Ended January 31,
	2013			2012
Beginning balance	$	39,629		$	36,407
Obligations incurred		2,606			2,350
Accretion expense		2,653			2,510
Payments		(2,304	)		(1,298	)
Ending balance	$	42,584		$	39,969

5. LONG-TERM DEBT AND CAPITAL LEASES

Amendment and Refinancing Transactions

On September 20, 2012, we entered into a second amendment to and consent under our senior secured first lien credit facility (the “Senior Credit Facility”). The amendment provided that we could use up to $50,000 of the senior secured revolving credit facility (the “2011 Revolver”) proceeds under the Senior Credit Facility to redeem our $180,000 in aggregate principal amount 11% senior second lien notes due 2014 (the “Second Lien Notes”) and to pay for any interest, fees, premium or other amounts in connection with the refinancing of the Second Lien Notes, subject to the terms and conditions to such use, as described in the amendment. The amendment also contains additional modifications, including increasing the allowed amount of senior subordinated debt from $350,000 to $450,000, adjusting the definition of bank-defined cash flow by allowing for certain add backs, adjusting the definition of consolidated total interest expense by allowing for an exclusion of non-cash interest expense associated with interest rate derivatives, and providing for adjustments to the financial covenants in the event that we tendered the Second Lien Notes.

On September 24, 2012, we initiated a cash tender offer and consent solicitation for our Second Lien Notes (the “Tender Offer”). On October 9, 2012, we repurchased $107,318 in aggregate principal amount of our then outstanding Second Lien Notes through the Tender Offer, leaving $72,682 in aggregate principal amount of Second Lien Notes outstanding. Holders who tendered the Second Lien Notes prior to the early tender date received $1,060 for each $1,000 in principal amount of Second Lien Notes repurchased, which included an early tender premium of $30 per $1,000 in principal amount of Second Lien Notes, plus accrued and unpaid interest to, but not including the early tender offer settlement date. On November 8, 2012, we redeemed the remaining $72,682 in aggregate principal amount the outstanding Second Lien Notes. The remaining holders who tendered the Second Lien Notes received $1,055 for each $1,000 in principal amount of Second Lien Notes redeemed, plus accrued and unpaid interest to, but not including the redemption date.

On October 9, 2012, we completed the offering of an additional $125,000 of 7.75% senior subordinated notes (the “2019 Notes”), which will mature on February 15, 2019. The 2019 Notes were issued at a discount of $1,863, which will be amortized to interest expense over the life of the 2019 Notes, with interest payable semiannually in arrears on February 15 and August 15 of each year, commencing February 15, 2013. The net proceeds from the offering of additional 2019 Notes, along with $50,000 of 2011 Revolver borrowings, $42,184 of net equity proceeds from the offering and sale of Class A common stock discussed in Note 7 and other available funds were used to redeem our Second Lien Notes in full and to pay related transaction costs.

The Senior Credit Facility, as amended, is subject to customary affirmative, negative and financial covenants. As of January 31, 2013, these covenants restrict fiscal year capital expenditures to 1.5 times our consolidated depreciation expenses, depletion expenses and landfill amortization expenses, set a minimum interest coverage ratio of 2.00, a maximum consolidated total funded debt to consolidated EBITDA ratio of 5.75 and a maximum senior funded debt to consolidated EBITDA ratio of 2.75. In addition to the financial covenants described above, the Senior Credit Facility, as amended, also contains a number of important 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 January 31, 2013, we were in compliance with all covenants under the indenture governing our Senior Credit Facility 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 to.

Loss on Debt Extinguishment

In the three months ended January 31, 2013, we recorded a charge of $5,914 as a loss on debt extinguishment related to the refinancing of our remaining Second Lien Notes. The loss on debt extinguishment consisted of a $1,100 non-cash write off of deferred financing costs, a $816 non-cash write off of the unamortized original issue discount and a $3,998 charge associated with the early tender premium and other fees associated with the redemption of the remaining Second Lien Notes.

In the nine months ended January 31, 2013, we recorded a charge of $15,584 as a loss on debt extinguishment related to the full refinancing of our Second Lien Notes. The loss on debt extinguishment consisted of a $2,667 non-cash write off of deferred financing costs, a $2,074 non-cash write off of the unamortized original issue discount and a $10,743 charge associated with the early tender premium and tender fees associated with the redemption of the Second Lien Notes.

Long Term Debt and Capital Leases

Long-term debt and capital leases as of January 31, 2013 and April 30, 2012 consist of the following:

	January 31,		April 30,
	2013		2012

6. CONTINGENCIES

(a) 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 the waste management business.

In accordance with 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 ASC 450-20-25-2. In instances where we determine that a loss is probable and we can reasonably estimate a range of losses 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 450-20-25-3. As of January 31, 2013, there were no accruals established related to our outstanding legal proceedings.

We offer no prediction of the outcome of any of the proceedings or negotiations described below. We are vigorously defending each of the unresolved lawsuits and claims described below. However, litigation is subject to inherent uncertainty and there can be no guarantee we will prevail or that any judgments against us, if sustained on appeal, will not have a material adverse effect on our business, financial condition, results of operations or cash flows.

Penobscot Energy Recovery Company Matter

On May 31, 2011, we received formal written notice from the Penobscot Energy Recovery Company (“PERC”) submitting to arbitration what it alleges is a disputed invoice in the amount of approximately $3,195 dated March 2, 2011. PERC contended that Pine Tree Waste, Inc., our subsidiary, failed since 2001 to honor a “put-or-pay” waste disposal arrangement. Arbitration of this matter was initiated, but in January 2012 a global settlement was reached in principle and memorialized in a letter of intent dated February 1, 2012, which documented the final terms of the settlement and dismissal of the arbitration action. The final global settlement documents were executed effective October 1, 2012. Pursuant to the terms of the settlement, we will not be required to make a cash payout. We anticipate that there may be nonmaterial incremental operational expenses that arise from implementing the terms of the settlement with regard to waste deliveries.

New York State Tax Litigation Matter

On January 18, 2011, certain of our subsidiaries doing business in New York State received a Notice of Deficiency (the “Notices”) from the New York State Department of Taxation and Finance asserting liability for corporation franchise tax for one or more of the tax years ended April 30, 2004 through April 30, 2006. The Notices, in the aggregate, assert liability of $3,852, comprising $2,220 of tax and $1,632 of penalties and interest. New York State has alleged that we are not permitted to file a single combined corporation franchise tax return with our subsidiaries for each of the years audited.

We filed Petitions for Redetermination (“Petitions”) with the State of New York Division of Tax Appeals on April 13-14, 2011, and an administrative hearing before a single tax tribunal administrative law judge on all Petitions that was scheduled for December 12, 2012 has been rescheduled to April 17-19, 2013. We expect to aggressively defend against this claim through the administrative adjudication and appeals process and the courts, if necessary. Under ASC 740, we believe our position will more likely than not be successful in contesting the deficiencies and consequently, we have not established any reserve for this matter.

(b) Environmental 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

16

contamination of drinking water sources or soil, possibly including damage resulting from conditions existing 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.

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, including the preparation of a Remedial Investigation and Feasibility Study (the “Study”). A draft of the Study was submitted to 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 will be approximately $10,219 and it is unlikely that any costs relating to onsite remediation will be incurred until fiscal year 2014. On February 28, 2011, the DEC issued a Proposal 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. A new Order on Consent and Administrative Settlement naming WSI and NiMo as Respondents was received by us on November 13, 2012, requiring that we enter into a Consent Order with DEC within 60 days and mandating implementation of the ROD. The deadline for execution of the Consent Order has recently been extended until March 27, 2013.

WSI is jointly and severally liable for the total cost to remediate and we initially expected to be responsible for approximately 30% upon implementation of a cost-sharing agreement with NiMo and GM. Based on these estimates, we recorded an environmental remediation charge of $2,823 in the third quarter of fiscal year 2009. In the fourth quarter of fiscal year 2009, we recognized an additional charge of $1,532, representing an additional 15% of the estimated costs, in recognition of the deteriorating financial condition and eventual bankruptcy filing of GM. In the fourth quarter of fiscal year 2010, we recognized an additional charge of $335 based on changes in the expected timing of cash outflows. Based on the estimated costs in the ROD, and changes in the estimated timing of cash flows, we recorded an environmental remediation charge of $549 in the fourth quarter of fiscal year 2011. Such charges could be significantly higher if costs exceed estimates. We inflate these estimated costs in current dollars until the expected time of payment and discount the cost to present value using a risk free interest rate (2.70%). At January 31, 2013 and April 30, 2012, we have recorded liabilities of $5,313 and $5,210, respectively, including the recognition of $34, $34, $103, and $103 of accretion expense in the three and nine months ended January 31, 2013 and 2012, respectively.

In September 2011, the DEC settled its environmental claim against the estate of the former GM (known as the “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. We expect the warrants to be issued in fiscal year 2013. We have not assumed that the payment of these claims will reduce our exposure.

7. STOCKHOLDERS’ EQUITY

(a) Stock Issuance

On October 3, 2012, in a registered public offering we sold 11,500 shares of Class A common stock at an average price of $4.00 per share. The net proceeds received from the registered public offering, after deducting underwriting discounts, commissions and offering expenses, were $42,184 and were used to refinance our Second Lien Notes.

(b) Stock Incentive Plans

In May 2012, we granted restricted stock units and performance stock units under the 2006 Stock Incentive Plan (the “2006 Plan”) to certain employees. The vesting of the performance stock units is based on our attainment of a targeted annual return on net assets in fiscal year 2015 and the vesting of the restricted stock units is based on continued employment over a three year period beginning on the grant date. As of January 31, 2013, the performance stock units included in the May 2012 grant could result in the issuance of up to 529 shares of Class A common stock based on the attainment of a targeted maximum annual return on net assets in fiscal year 2015 and the restricted stock units could result in the issuance of an aggregate of up to 264 shares of Class A common stock based on continued employment over the remainder of the three year service period. The performance stock units and the restricted stock units were granted at a grant date fair value of $5.17 per share.

17

As of January 31, 2013, we had 1,320 Class A common stock equivalents available for future grant under the 2006 Plan, inclusive of additional Class A common stock equivalents which were previously issued under our terminated plans but which have become available for grant because such awards expired or otherwise resulted in shares not being issued.

Stock options granted generally vest over a one to four year period from the date of grant and are granted at prices equal to the prevailing fair market value at the issue date. In general, stock options are issued with a life not to exceed ten years. Shares issued by us upon exercise of stock options are issued from the pool of authorized shares of Class A common stock.

A summary of stock option activity for the nine months ended January 31, 2013 is as follows:

	Stock Options			Weighted Average Exercise Price
Outstanding, April 30, 2012		1,661		$	10.55
Granted		285		$	4.03
Exercised		—		$	—
Forfeited		(589	)	$	11.43
Outstanding, January 31, 2013		1,357		$	8.81
Exercisable, January 31, 2013		981		$	10.64

A summary of restricted stock, restricted stock unit and performance stock unit activity for the nine months ended January 31, 2013 is as follows:

	Restricted Stock / Restricted Stock Units			Weighted Average Grant Price		Performance Stock Units (1)			Weighted Average Grant Price
Outstanding, April 30, 2012		784		$	4.47		596		$	4.96
Granted		415		$	5.02		316		$	5.17
Class A Common Stock Vested		(489	)	$	4.01		—		$	—
Forfeited		(69	)	$	4.82		(166	)	$	5.01
Outstanding, January 31, 2013		641		$	5.09		746		$	5.04

(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 435 shares of Class A common stock.

We recorded $232, ($91), $1,486 and $1,222 of stock-based compensation expense (income) related to stock options, performance stock units, restricted stock units and restricted stock, respectively, during the three and nine months ended January 31, 2013 and 2012. We also recorded $22, $33, $75 and $85 of stock-based compensation expense related to our Employee Stock Purchase Plan during the three and nine months ended January 31, 2013 and 2012, respectively.

Stock-based compensation expense is included in general and administration expenses in the unaudited consolidated statements of operations. The unrecognized stock-based compensation expense at January 31, 2013 related to unvested stock options, restricted stock and restricted stock units was $3,017, to be recognized over a weighted average period of 1.70 years. Maximum unrecognized stock-based compensation expense at January 31, 2013 related to outstanding performance stock units, and subject to the attainment of targeted maximum annual returns on net assets, was $5,219, to be recognized over a weighted average period of 1.39 years. The unrecognized stock-based compensation expense that we expect to recognize as of January 31, 2013 related to outstanding performance stock units based on our expected attainment levels was $0.

18

Our calculations of stock-based compensation expense associated with stock options and our Employee Stock Purchase Plan for the three and nine months ended January 31, 2013 and 2012 were made using the Black-Scholes valuation model. The fair value of stock options grants and shares to be purchased under our Employee Stock Purchase Plan were estimated assuming no expected dividend yield using the following weighted average assumptions for the three and nine months ended January 31, 2013 and 2012:

	Three Months Ended January 31,						Nine Months Ended January 31,
	2013			2012			2013			2012
Stock Options:
Expected life		6.79 years			—			6.79 years			—
Risk-free interest rate		1.04	%		0.00	%		1.04	%		0.00	%
Expected volatility		84.55	%		0.00	%		84.55	%		0.00	%
	Three Months Ended January 31,						Nine Months Ended January 31,
	2013			2012			2013			2012
Employee Stock Purchase Plan:
Expected life		0.5 years			0.5 years			0.5 years			0.5 years
Risk-free interest rate		0.12	%		0.06	%		0.11	%		0.12	%
Expected volatility		53.09	%		53.78	%		43.73	%		47.54	%

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 unaudited consolidated statements of operations.

(c) Noncontrolling Interest

Casella-Altela Regional Environmental Services, LLC (“CARES”) is a joint venture that develops, owns and operates water and leachate treatment projects for the natural gas drilling industry in Pennsylvania and New York. Our joint venture partner in CARES is Altela, Inc. On December 13, 2012, we entered into an agreement with Altela, Inc., which increased our membership interest in CARES from 51% to 66.1% subject to a one-year claw back provision. We recorded an adjustment to reduce the noncontrolling interest by $258 to reflect the change in ownership interest in CARES. We consolidate the assets, liabilities, noncontrolling interest, and results of operations of CARES into our unaudited consolidated financial statements due to our controlling financial interest in the joint venture.

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.

Our financial instruments include cash and cash equivalents, trade receivables, restricted trust and escrow accounts, commodity and interest rate derivatives, trade payables and long-term debt. The carrying values of cash and cash equivalents, trade receivables and trade payables approximate their respective fair values. At January 31, 2013, the fair value of our fixed rate debt, including the 2019 Notes and the Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-2 due January 1, 2025 (the “Converted Bonds”) was approximately $342,349 and the carrying value was $344,608. 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 Converted 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 the Converted Bonds or securities with similar characteristics. As of January 31, 2013, the fair value of the 2011 Revolver approximated its carrying value of $141,700 based on current borrowing rates for similar types of borrowing arrangements.

As of January 31, 2013 our assets and liabilities that are measured at fair value on a recurring basis included the following:

	Active Markets for		Significant Other		Significant

As of April 30, 2012 our assets and liabilities that are measured at fair value on a recurring basis included the following:

	Fair Value Measurement at April 30, 2012 Using:
	Quoted Prices in
	Active Markets for		Significant Other		Significant

Assets:
Restricted assets	$	424	$	—	$	—
Liabilities:
Interest rate derivatives	$	—	$	2,369	$	—

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 to hedge the interest rate risk associated with the forecasted financing transaction to redeem our Second Lien Notes effective January 15, 2013. The total notional amount of these agreements is $150,000 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.

For interest rate derivatives deemed to be effective cash flow hedges, the change in fair value is recorded in our stockholders’ equity as a component of accumulated other comprehensive loss and included in interest expense at the same time as interest expense is affected by the hedged transaction. Differences paid or received over the life of the agreements are recorded as additions to or reductions of interest expense of the underlying debt. For interest rate derivatives deemed to be ineffective cash flow hedges, the change in fair value is recorded through earnings and included in (gain) loss on derivative instruments.

We dedesignated both of the $75,000 forward starting interest rate derivative agreements and discontinued hedge accounting in accordance with ASC 815-30 in the second quarter of fiscal year 2013 because the interest payments associated with the forecasted financing transaction were no longer deemed probable due to the redemption of our Second Lien Notes as discussed in Note 5. We recognized a $3,626 loss, reclassified from accumulated other comprehensive loss, as a loss on derivative instruments in the second quarter of fiscal year 2013.

The fair values of the interest rate derivatives are obtained from third-party counter-parties and adjusted based on the credit risk of our counter-parties and us. We recognize all derivatives on the balance sheet at fair value.

10. INCOME TAXES

The benefit for income taxes for the three and nine months ended January 31, 2013 includes a $5,242 deferred tax benefit due to a reduction of the valuation allowance. In determining the need for a valuation allowance, we have assessed the available means of recovering deferred tax assets, including the existence of reversing temporary differences. The valuation allowance decreased due to the recognition of additional reversing temporary differences from the $5,242 deferred tax liability recorded

21

through goodwill related to the BBI acquisition. The $5,242 deferred tax liability related to the BBI acquisition was based on the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for income tax purposes. The remaining portion of the $3,899 benefit for income taxes for the nine months ending January 31, 2013 and the $1,330 provision for income taxes for the nine months ending January 31, 2012 include $1,176 and $1,085 deferred tax provisions, respectively, due mainly to the increase in the deferred tax liability for indefinite lived assets and a $167 and $245 current tax provision, respectively. 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.

11. DEVELOPMENT PROJECT CHARGE

In the second quarter of fiscal year 2012, we recorded a charge of $131 for deferred costs associated with certain development projects no longer deemed viable. As of January 31, 2013 and April 30, 2012, we had $1,554 and $1,163 of deferred costs associated with development projects included in other non-current assets within our unaudited consolidated balance sheets.

12. SEVERANCE AND REORGANIZATION

On August 8, 2012, we realigned our operations in order to streamline functions and improve our cost structure. Through the reorganization we have targeted improvements in certain aspects of the sales function to better facilitate customer service and retention, pricing growth, and support of strategic growth initiatives; better aligned transportation, route management and maintenance functions at the local level; and reduced corporate overhead and staff to match organizational needs and reduce costs. We recorded a one-time severance and reorganization charge of $1,793 in the second quarter of fiscal year 2013 with respect to the realignment.

In the three months ended January 31, 2013, we recorded a $1,636 severance charge related primarily to the closing of Maine Energy Recovery Company LP (“Maine Energy”), see Note 13 for further discussion, and a reorganization of senior management. The liability associated with severance and reorganization as of January 31, 2013, which is recorded in other accrued liabilities, is $1,111.

13. DIVESTITURE AND DISCONTINUED OPERATIONS

Maine Energy Divestiture

On August 1, 2012, we executed a purchase and sale agreement with the City of Biddeford, Maine pursuant to which we agreed to sell the real property of Maine Energy, which is located in our Eastern region, to the City of Biddeford, subject to satisfaction of conditions precedent and closing. We agreed to sell Maine Energy for undiscounted purchase consideration of $6,650, which shall be paid to us in equal installments over the next 21 years, subject to the terms of the purchase and sale agreement. The transaction closed on November 30, 2012, and we waived certain conditions precedent not satisfied at that time. Effective December 31, 2012, we closed the facility and initiated the decommissioning process in accordance with the provisions of the agreement. Following the decommissioning of Maine Energy, it is our responsibility to demolish the facility, at our cost, within twelve months of the closing date and in accordance with the terms of the purchase and sale agreement. We recorded a charge to loss on divestiture of $353 in the three months ended January 31, 2013 as a result of this transaction.

As a part of the closure and decommissioning of Maine Energy, we are withdrawing from a multiemployer pension plan that we have made contributions to for the benefit of Maine Energy employees covered under a collective bargaining agreement. We have a potential liability associated with our withdrawal from the multiemployer pension plan based on the value of the plan’s unfunded vested benefits. In accordance with ASC 715-80, in a situation with unfunded vested benefits, a liability is not recorded by a participating employer as no single employer has an identifiable share of the actuarial obligation of the multiemployer pension plan.

In accordance with ASC 450-20, we accrue for an obligation when an obligation becomes probable and reasonably estimable. We currently believe that an obligation associated with withdrawal from the multiemployer pension plan is probable, but we cannot reasonably estimate the amount of loss or possible range of loss due to a lack of information being made available by the fund administrator in regards to the unfunded vested benefits. The fund administrator will quantify our withdrawal liability based on the unfunded vested benefits as of the plan year preceding actual withdrawal. As we expect to completely withdraw from the plan in early fiscal year 2014, we expect the plan administrator to base our obligation on the plan year ended January 31, 2013. We expect to record an obligation associated with our portion of unfunded vested benefits in fiscal year 2014. As of January 31, 2013, no accrual is established related to withdrawal from the multiemployer pension plan.

22

Discontinued Operations

On January 23, 2011, we entered into a purchase and sale agreement and related agreements to sell non-integrated recycling assets and select intellectual property assets to a new company (the “Purchaser”) formed by Pegasus Capital Advisors, L.P. and Intersection LLC. Pursuant to these agreements, we divested non-integrated recycling assets located outside our core operating regions of New York, Massachusetts, Vermont, New Hampshire, Maine and northern Pennsylvania, including 17 material recovery facilities (“MRFs”), one transfer station and certain related intellectual property assets. Following the transaction, we retained four integrated MRFs located in our core operating regions. As a part of the disposition, we also entered into a ten-year commodities marketing agreement with the Purchaser to market 100% of the tonnage from three of our remaining integrated MRFs.

We completed the transaction on March 1, 2011 for $134,195 in gross cash proceeds. This included an estimated $3,795 working capital and other purchase price adjustment, which was subject to further adjustment, as defined in the purchase and sale agreement. The final working capital adjustment, along with additional legal expenses related to the transaction, of $646 was recorded to gain on disposal of discontinued operations, net of income taxes in the first quarter of fiscal year 2012.

In the second quarter of fiscal year 2012, we recorded an additional working capital adjustment of $79 to gain on disposal of discontinued operations, net of income taxes, which related to our subsequent collection of receivable balances that were released to us for collection by the Purchaser.

14. 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 are derived mainly from collection, transfer, disposal, landfill, landfill-gas-to energy, recycling and organic 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. Ancillary operations, major customer accounts, discontinued operations, and earnings from equity method investees are included in our “Other” reportable segment. Segment data for the three and nine months ended January 31, 2012 has been revised to properly align with internal management reporting.

15. INVESTMENTS IN UNCONSOLIDATED ENTITIES

Equity Method Investments

GreenFiber. We entered into a joint venture agreement in July 2000 with Louisiana-Pacific Corporation (“LP”) to combine our respective cellulose insulation businesses into a single operating entity, US GreenFiber LLC (“GreenFiber”). We account for our 50% membership interest in GreenFiber using the equity method of accounting.

In April 2011, we issued a guaranty in support of GreenFiber’s amended and restated loan and security agreement. The guaranty can be drawn on upon an event of default and remains in place through December 1, 2014, the extended term of GreenFiber’s modified and restated loan and security agreement. Our guaranty associated with the credit facility is $2,200 as of January 31, 2013. The fair value of our guaranty as of January 31, 2013, which is recorded in other long-term liabilities, is $264.

As of December 31, 2011, GreenFiber performed a test for goodwill impairment. The goodwill impairment analysis indicated that the carrying value of their reporting unit exceeded the fair value of their reporting unit, and GreenFiber determined that the entire amount of their goodwill was impaired. Consequently, we recorded our portion of the goodwill impairment charge of $5,090 as a part of the loss on equity method investment in the third quarter of fiscal year 2012.

Based on the analysis performed, we determined that the current book value of our investment in GreenFiber at that time exceeded its fair value. The analysis calculated GreenFiber’s fair value based on the income approach using discounted cash flows taking into account current expectations for asset utilization, housing starts and the remaining useful life of related assets. We recorded a charge of $10,680 as an impairment on equity method investment in the third quarter of fiscal year 2012.

In May 2012, we and LP made identical commitments to fund any liquidity shortfalls of GreenFiber related to covenant compliance as defined in and through the term of GreenFiber’s modified and restated loan and security agreement. Based on the terms of this agreement, in May 2012, we and LP made identical equity contributions to GreenFiber of $500 to cure such shortfall.

Our investment in GreenFiber amounted to $2,638 and $6,502 at January 31, 2013 and April 30, 2012, respectively. Summarized financial information for GreenFiber is as follows:

	January 31, 2013		April 30, 2012
Current assets	$	15,470	$	17,513
Noncurrent assets	$	30,246	$	34,597
Current liabilities	$	14,406	$	12,815
Noncurrent liabilities	$	5,126	$	5,382

Tompkins. In May 2011, we finalized the terms of a joint venture agreement with FCR, LLC (“FCR”) to form Tompkins County Recycling LLC (“Tompkins”), a joint venture that operates a MRF located in Tompkins County, NY and processes and sells commodities delivered to the Tompkins MRF. In connection with the formation of the joint venture, we acquired a 50% membership interest in Tompkins in exchange for an initial cash contribution to Tompkins of $285. FCR made an initial cash contribution of $285 as well, and acquired a 50% membership interest in Tompkins. Income and losses are allocated to members based on membership interest percentage. Our investment in Tompkins amounted to $307 and $292 at January 31, 2013 and April 30, 2012, respectively. We account for our 50% membership interest in Tompkins using the equity method of accounting.

Cost Method Investments

Evergreen. Our investment and ownership interest in Evergreen National Indemnity Company, a surety company which provides surety bonds to us and other parties, amounted to $10,657 and 19.9%, as of January 31, 2013 and April 30, 2012.

RecycleRewards. Our investment and ownership interest in RecycleRewards, Inc., a company that markets an incentive based recycling service, amounted to $4,479 and 6.0% as of January 31, 2013 and $4,479 and 6.2% as of April 30, 2012.

AGreen. In May 2011, we entered into a renewable energy project operating agreement with AGreen Energy LLC (“AGreen”). As a part of the agreement, we provide certain operation, maintenance and administrative services, as well as procure organic materials that would otherwise be disposed of to small farm-based biogas renewable energy projects that produce renewable energy and other valuable products and services. Our investment and membership interest in AGreen amounted to $350 and 11.9% as of January 31, 2013 and April 30, 2012.

GreenerU . In March 2012, we entered into a strategic partnership agreement with GreenerU, Inc. (“GreenerU”), a company that delivers energy and sustainability solutions to the college, university and preparatory school markets in order to reduce their energy costs and carbon emissions through the formulation of programs and policies and the running of renewable energy projects. As a part of the agreement, we work with GreenerU to formulate compelling offers and approaches for colleges, universities and preparatory schools in the area of waste, recycling, energy, composting, resource conservation and other appropriate sustainability initiatives. In the first quarter of fiscal year 2013, we made a $500 investment in GreenerU through the purchase of preferred stock, bringing our investment and ownership interest in GreenerU to $1,000 and 6.3% as of January 31, 2013. Our investment and ownership interest in GreenerU was $500 and 4.2% as of April 30, 2012.

Company Overview

Founded in 1975 with a single truck, Casella Waste Systems, Inc. is a regional, vertically-integrated solid waste, recycling, and resource management services company. We provide resource management expertise and services to residential, commercial, municipal and industrial customers, primarily in the areas of solid waste collection, transfer, disposal, recycling and organics services. We operate 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 includes a full range of solid waste services, and our larger-scale recycling operations and commodity brokerage operations through our Recycling segment. Ancillary operations, major customer accounts, discontinued operations and earnings from equity method investees are included in our Other segment.

As of February 28, 2013, we owned and/or operated 35 solid waste collection operations, 38 transfer stations, 16 recycling facilities, nine Subtitle D landfills, four landfill gas-to-energy facilities and one landfill permitted to accept construction and demolition materials. In addition to our primary operations, we also hold the following investments:

Consolidated Investment with Noncontrolling Interest

Casella-Altela Regional Environmental Services, LLC (“CARES”) is a joint venture that develops, owns and operates water and leachate treatment projects for the natural gas drilling industry in Pennsylvania and New York. Our joint venture partner in CARES is Altela, Inc. On December 13, 2012, we entered into an agreement with Altela, Inc., which increased our membership interest in CARES from 51% to 66.1% subject to a one-year claw back provision. We recorded an adjustment to reduce the noncontrolling interest by $0.3 million to reflect the change in ownership interest in CARES. We consolidate the assets, liabilities, noncontrolling interest, and results of operations of CARES into our unaudited consolidated financial statements due to our controlling financial interest in the joint venture.

In the nine months ended January 31, 2013, we and Altela, Inc. made additional cash contributions of $3.2 million and $1.2 million, respectively, for the purchase of additional equipment and to fund operations. The initial CARES water treatment facility began operating at our McKean County Pennsylvania landfill in the second quarter of fiscal year 2013.

Equity Method Investments

GreenFiber. We entered into a joint venture agreement in July 2000 with Louisiana-Pacific Corporation (“LP”) to combine our respective cellulose insulation businesses into a single operating entity, US GreenFiber LLC (“GreenFiber”), that manufactures, markets and sells cellulose insulation made from recycled fiber. We account for our 50% membership interest in GreenFiber using the equity method of accounting.

In April 2011, we issued a guaranty in support of GreenFiber’s amended and restated loan and security agreement. The guaranty can be drawn on upon an event of default and remains in place through December 1, 2014, the extended term of GreenFiber’s modified and restated loan and security agreement. Our guaranty associated with the credit facility is $2.2 million as of January 31, 2013.

In May 2012, we and LP also made identical commitments to fund any liquidity shortfalls of GreenFiber related to covenant compliance as defined in and through the term of GreenFiber’s modified and restated loan and security agreement. Based on the terms of this agreement, in May 2012, we and LP made identical equity contributions to GreenFiber of $0.5 million to cure such shortfall.

Tompkins. In May 2011, we finalized the terms of a joint venture agreement with FCR, LLC (“FCR”) to form Tompkins County Recycling LLC (“Tompkins”), a joint venture that operates a material recovery facility (“MRF”) located in Tompkins County, New York and processes and sells commodities delivered to the Tompkins MRF. We account for our 50% membership interest in Tompkins using the equity method of accounting.

40

Cost Method Investments

We have cost method investments in AGreen Energy LLC (“AGreen”), RecycleRewards, Inc. (“RecycleRewards”), GreenerU, Inc. (“GreenerU”), and Evergreen National Indemnity Company (“Evergreen”), as follows:

We hold a 11.9% membership interest in AGreen, a joint venture that brings advanced nutrient management, renewable energy and water technologies to small and medium sized farms, a 6.0% ownership interest in RecycleRewards, a company that markets an incentive based recycling service, a 6.3% ownership interest in GreenerU, a company that delivers energy and sustainability solutions to the college, university and preparatory school market in order to reduce their energy costs and carbon emissions through the formulation of programs and policies and the running of renewable energy projects, and a 19.9% interest in Evergreen, a surety company which provides surety bonds to secure contractual performance for municipal solid waste collection contracts and landfill closure and post-closure obligations.

In the nine months ended January 31, 2013, cash outflows related to our cost method investments consisted of a $0.5 million investment in GreenerU through the purchase of preferred stock, which brought our ownership interest in GreenerU to 6.3% as of January 31, 2013.

Acquisitions and Divestitures

During the nine months ended January 31, 2013, we acquired four solid waste hauling operations in the Western region for total consideration of $5.4 million, including $4.9 million in cash and $0.5 million in holdbacks to the sellers, and all of the outstanding capital stock of Bestway Disposal Services and BBI Waste Services (“BBI”) in the Eastern region for total consideration of $22.6 million, including $20.0 million in cash and approximately 0.6 million shares of our Class A common stock, valued at an aggregate of $2.6 million. We recorded an additional $5.2 million to goodwill for the increased deferred tax liability related to the BBI acquisition based on the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for income tax purposes. The acquisition of BBI, a provider of solid waste collection, transfer and liquid waste services in New Hampshire and Maine, provides us the opportunity to internalize additional waste and recyclables and to consolidate operations, routes and transportation within the Eastern region. Revenue generated from BBI amounted to $2,9 million from December 6, 2012 to January 31, 2013.

On August 1, 2012, we executed a purchase and sale agreement with the City of Biddeford, Maine pursuant to which we agreed to sell the real property of Maine Energy Recovery Company LP (“Maine Energy”), which resides in our Eastern region, to the City of Biddeford, subject to satisfaction of conditions precedent and closing. We agreed to sell Maine Energy for undiscounted purchase consideration of $6.7 million, which shall be paid to us in equal installments over the next 21 years, subject to the terms of the purchase and sale agreement. The transaction closed on November 30, 2012 and we waived certain conditions precedent not satisfied at that time. Effective December 31, 2012, we closed the facility and initiated the decommissioning process in accordance with the provisions of the agreement. Following the decommissioning of Maine Energy, it is our responsibility to demolish the facility, at our cost, within twelve months of the closing date and in accordance with the terms of the purchase and sale agreement. We recorded a charge to loss on divestiture of $0.4 million in the three months ended January 31, 2013 as a result of this transaction.

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 disposal and collection, landfill, landfill gas-to-energy, transfer, recycling and organics 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 from the sale of recyclable commodities and operations and maintenance contracts of recycling facilities for municipal customers. Revenues from our Other segment are made up of ancillary revenues including major customer accounts.

Our revenues are shown net of inter-company eliminations. We typically establish our inter-company transfer pricing based upon prevailing market rates. The table below shows, for the periods indicated, the percentages and dollars (in millions) of revenue attributable to services provided.

Solid Waste Revenues

• The price change component in quarterly total solid waste revenue growth period-to-period is the result of $0.9 million from favorable collection pricing and $0.1 million from favorable disposal pricing. The price change component in year-to-date total solid waste revenue decline period-to-period is the result of $1.4 million from favorable collection pricing, partially offset by $0.5 million from unfavorable disposal pricing.

• The volume change component in quarterly total solid waste revenue growth period-to-period is the result of $1.8 million from collection volume decreases and $0.6 million from disposal volume decreases, partially offset by $1.1 million from organics and processing volume increases. The volume change component in year-to-date total solid waste revenue decline period-to-period is the result of $6.5 million from collection volume decreases and $2.7 million from disposal volume decreases, partially offset by $1.7 million from organics and processing volume increases.

43

• The commodity price and volume change component in quarterly total solid waste revenue growth period-to-period is the result of $0.9 million from favorable pricing within power generation, $0.6 million from organics and processing volume increases and 0.2 million from favorable pricing within organics and processing, partially offset by $0.2 million from power generation volume decreases. The commodity price and volume change component in year-to-date total solid waste revenue decline period-to-period is the result of $1.6 million from power generation volume decreases, $0.2 million from organics and processing volume decreases, partially offset by $0.5 million from favorable pricing within power generation and $0.3 million from favorable pricing within organics and processing.

• The acquisitions and divestitures change component in quarterly total solid waste revenue growth period-to-period is the result of $4.0 million in increased revenues from acquisitions, $3.2 million of which relates to increased collections revenues, partially offset by $1.5 million in decreased revenues associated with the closure of Maine Energy. The acquisitions and divestitures change component in year-to-date total solid waste revenue decline period-to-period is the result of $6.1 million in increased revenues from acquisitions, $4.9 million of which relates to increased collections revenues, offset partially by $0.5 million in decreased revenues associated with the closure of Maine Energy.

• The closed landfill change component in quarterly and year-to-date total solid waste revenue fluctuation period-to-period is the result of a landfill in the Eastern region that stopped accepting waste in the second quarter of fiscal year 2013 based on the attainment of its permitted capacity.

Major Accounts and Recycling Revenues

• The change component in quarterly and year-to-date major accounts revenue decline period-to-period is primarily the result of $0.6 million and $2.4 million from volume declines.

• The change component in quarterly and year-to-date recycling revenue decline is the result of $1.2 million and $9.2 million from unfavorable pricing due to declining commodity prices in the marketplace, offset partially by $0.2 million and $0.9 million in volume increases.

Operating Expenses

Cost of Operations

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

Our cost of operations expense increased by $2.8 million, or 3.4%, and $1.2 million, or less than one-percent, when comparing the three and nine months ended January 31, 2013 to the prior fiscal year periods. In the three and nine months ended January 31, 2013, cost of operations increased as a percentage of revenues when compared to the prior fiscal year periods from 71.0% to 73.2% and from 68.1% to 71.4%. The period-to-period changes in our cost of operations can largely be attributed to the following:

• Hauling costs. Hauling costs increased $0.5 million when comparing the three months ended January 31, 2013 to the prior fiscal year period due primarily to increased transportation costs associated with a higher volume of organic materials being processed within organics and processing. When comparing hauling costs for the nine months ended January 31, 2013 to the prior fiscal year period costs decreased $0.9 million due to reduced transportation costs associated primarily with lower solid waste volumes within collections and disposal.

• Direct operational costs. Direct operational costs increased $0.5 million and $1.4 million when comparing the three and nine months ended January 31, 2013 to the prior fiscal year periods. The period-to-period change in the three and nine months ended January 31, 2013 is primarily the result of increases in various direct operational costs including equipment rental and lease costs, $0.5 million and $0.7 million, and depletion of landfill operating lease obligations, $0.4 million and $0.8 million, partially offset by a reduction in host community fees and royalties,

44

$0.5 million and $0.6 million. The period-to-period change in the nine months ended January 31, 2013 also included an increase of $0.5 million associated with a decrease in the gain related to the sale of fixed assets in the first two quarters of fiscal year 2013, substantially offset by reduced leachate disposal costs of $0.4 million in the first two quarters of fiscal year 2013 due to lower rainfall amounts at our landfills.

• Disposal costs. Third-party disposal costs associated with our reliance on third-party disposal sites increased $1.0 million and $2.5 million when comparing the three and nine months ended January 31, 2013 to the prior fiscal year periods.

• Benefit costs. Benefit costs associated with health and dental insurance and workers’ compensation insurance increased $0.7 million and $1.1 million when comparing the three and nine months ended January 31, 2013 to the prior fiscal year periods.

• Purchased material costs. Direct costs related to purchased materials decreased $0.7 million and $4.6 million, and as a percentage of revenue, when comparing the three and nine months ended January 31, 2013 to the prior fiscal year periods due primarily to lower commodity prices in the marketplace.

General and Administration

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

Our general and administration expense increased $0.6 million, or 4.3%, and decreased $2.4 million, or 5.2%, when comparing the three and nine months ended January 31, 2013 to the prior fiscal year periods. In the three months ended January 31, 2013, general and administration expenses increased as a percentage of revenues when compared to the prior fiscal year period from 12.2% to 12.6%, whereas in the nine months ended January 31, 2013 general and administration expenses decreased as a percentage of revenues when compared to the prior fiscal year period from 12.4% to 12.3%. The period-to-period changes in our general and administration expense can largely be attributed to the following:

• Personnel costs. For the three months ended January 31, 2013, labor, benefits and other personnel costs increased by $0.5 million when compared to the prior fiscal year period due primarily to additional costs associated with the BBI acquisition and a $0.3 million increase in equity compensation resulting from an expense reversal in the prior fiscal year period due to changes in expected attainment levels associated with performance stock units.

• Bad debt expense. For the three months ended January 31, 2013, bad debt expense increased by $0.4 million when compared to the prior fiscal year period due to changes in our collectible accounts.

• Legal fees. In the three and nine months ended January 31, 2013, legal costs decreased $0.3 million and $1.1 million when compared to the prior fiscal year periods due primarily to fewer ongoing legal proceedings.

• Other general and administration costs. In the nine months ended January 31, 2013, other general and administration costs decreased by $1.5 million due primarily to additional cost savings associated with the reorganization in the second quarter of fiscal year 2013.

Depreciation and Amortization

Depreciation and amortization expense includes depreciation of fixed assets over the estimated useful life of the assets using the straight-line method, amortization of landfill airspace assets under the units-of-consumption method, and the amortization of intangible assets (other than goodwill) using the straight-line method. We amortize landfill retirement assets through a charge to cost of operations using a straight-line rate per ton as landfill airspace is utilized. The amount of landfill amortization expense related to airspace consumption can vary materially from landfill to landfill depending upon the purchase price and landfill site and cell development costs. We amortize or depreciate all fixed and intangible assets, other than goodwill, to a zero net book value, and do not apply a salvage value to any fixed assets.

We capitalize certain direct landfill development costs, such as engineering, permitting, legal, construction and other costs associated directly with the expansion of existing landfills. Additionally, we also capitalize certain third party expenditures

45

related to development projects and pending acquisitions, such as legal and engineering costs. We routinely evaluate all such capitalized costs, and expense those costs related to projects not likely to be successful. Internal and indirect landfill development and acquisition costs, such as executive and corporate overhead, public relations and other corporate services, are expensed as incurred.

We have material financial obligations relating to capping, closure and post-closure costs of our existing landfills and disposal facilities. We have provided accruals for these future financial obligations based on engineering estimates of consumption of permitted landfill airspace over the useful life of any such landfill. There can be no assurance that our financial obligations for capping, closure or post-closure costs will not exceed the amount accrued and reserved or amounts otherwise receivable pursuant to trust funds.

Our depreciation and amortization expense decreased $0.9 million, or 6.0%, and $1.0 million, or 2.3%, when comparing the three and nine months ended January 31, 2013 to the prior fiscal year periods. In the three months ended January 31, 2013, depreciation and amortization expense decreased as a percentage of revenues when compared to the prior fiscal year period from 13.0% to 12.2%, whereas in the nine months ended January 31, 2013 depreciation and amortization expense increased as a percentage of revenues when compared to the prior fiscal year period from 11.9% to 12.2%. Landfill amortization expense decreased $0.4 million in the three months ended January 31, 2013 and increased $0.7 million in the nine months ended January 31, 2013, respectively, when compared to prior fiscal year periods due to volume fluctuations at our landfills, including volume reductions within the Western region and volume increases within the Eastern region, primarily at our Southbridge landfill. Depreciation expense decreased $0.6 million and $2.0 million when compared to prior fiscal year periods associated largely with the Maine Energy impairment in the fourth quarter of fiscal year 2012 and the Maine Energy divestiture in the three months ended January 31, 2013, which reduced our depreciable asset base.

Severance and Reorganization Costs

On August 8, 2012, we realigned our operations in order to streamline functions and improve our cost structure. Through the reorganization we have targeted improvements in certain aspects of the sales function to better facilitate customer service and retention, pricing growth, and support of strategic growth initiatives; better aligned transportation, route management and maintenance functions at the local level; and reduced corporate overhead and staff to match organizational needs and reduce costs. We recorded a one-time severance and reorganization charge of $1.8 million in the second quarter of fiscal year 2013 with respect to the realignment.

In the three months ended January 31, 2013, we recorded a $1.6 million severance charge related primarily to the closing of Maine Energy and a reorganization of senior management. The liability associated with severance and reorganization as of January 3, 2013, which is recorded in other accrued liabilities, is $1.1 million.

Expense from Divestiture, Acquisition and Financing Costs

The $1.0 million expense from divestiture, acquisition and financing costs is associated with the following fiscal year 2013 events: a $0.3 million write-off of costs associated with the attempted refinancing of our senior second lien notes in the first quarter of fiscal year 2013 (the “Second Lien Notes”), $0.6 million of legal costs associated with the ongoing Maine Energy divestiture transaction and $0.1 million of costs associated with the BBI acquisition.

Other Expenses

Interest Expense, net

Our interest expense, net decreased $2.1 million, or 18.3%, and $1.0 million, or 2.9%, when comparing the three and nine months ended January 31, 2013 to the prior fiscal year periods. In the three months ended January 31, 2013, interest expense, net decreased as a percentage of revenues when compared to the prior fiscal year period from 10.0% to 8.1%, whereas in the nine months ended January 31, 2013, interest expense, net increased as a percentage of revenues when compared to the prior fiscal year period from 9.1% to 9.2%. The period-to-period changes in our interest expense, net can largely be attributed to the following:

• Second Lien Notes. Interest expense in the three and nine months ended January 31, 2013 decreased from the prior fiscal year periods due to the redemption of our previously outstanding 11.0% Second Lien Notes. These interest expense savings were partially offset by the following items.

• Maine Bonds. Interest expense in the three and nine months ended January 31, 2013 increased due to the conversion from a variable rate to a five year fixed term interest rate of 6.25% per annum on the $21.4 million Finance Authority of Maine (the “Authority”) Solid Waste Disposal Revenue Bonds Series 2005R-2 (the “Converted Bonds”) in the fourth quarter of fiscal year 2012.

• Higher debt levels. Interest expense in the three and nine months ended January 31, 2013 increased due to higher average debt balances associated primarily with borrowings on the amended and restated senior secured revolving credit facility (the “2011 Revolver”) in the current fiscal year periods to redeem the Second Lien Notes and help fund operations and meet cash flow needs.

Loss from Equity Method Investments

Our loss from equity method investments decreased $4.9 million and $6.8 million when comparing the three and nine months ended January 31, 2013 to the prior fiscal year periods. Our equity method investments consist of the following investments:

• GreenFiber. GreenFiber reported losses for the three months ended January 31, 2013 and 2012, of which our 50% share was $1.4 million, and $6.4 million, respectively. GreenFiber reported losses for the nine months ended January 31, 2013 and 2012, of which our 50% share was $3.3 million and $10.2 million, respectively. Despite the improvement from prior fiscal year periods, which also included our portion of a goodwill impairment charge amounting to $5.1 million, GreenFiber has continued to be negatively affected by the depressed manufactured home market and lack of new home construction.

• Tompkins County. We account for our 50% membership interest in Tompkins using the equity method of accounting. Our portion of the reported income from Tompkins for the three and nine months ended January 31, 2013 was immaterial.

(Benefit) Provision for Income Taxes

Our (benefit) provision for income taxes decreased $5.6 million and $5.2 million when comparing the three and nine months ended January 31, 2013 to the prior fiscal year periods. The benefit for income taxes for the three and nine months ended January 31, 2013 includes a $5.2 million deferred tax benefit due to a reduction of the valuation allowance. The valuation allowance decreased based upon the recognition of additional reversing temporary differences related to the $5.2 million deferred tax liability recorded through goodwill related to the BBI acquisition. The $5.2 million deferred tax liability related to the BBI acquisition was based on the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and the related tax basis. The remaining portion of the $3.9 million benefit for income taxes for the nine months ending January 31, 2013 and the $1.3 million provision for income taxes for the nine months ending January 31, 2012 include $1.2 million and $1.1 million deferred tax provisions due mainly to the increase in the deferred tax liability for indefinite lived assets and $0.2 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.

47

Discontinued Operations

Gain on Disposal of Discontinued Operations, net

The $0.7 million gain on disposal of discontinued operations (net of tax) recorded in the nine months ended January 31, 2012 is due to the additional working capital adjustment and other legal expenses recorded in the first quarter of fiscal year 2012 related to the sale of non-integrated recycling assets and select intellectual property assets to ReCommunity, the company formed by Pegasus Capital Advisors, L.P. and Intersection LLC, and an additional working capital adjustment due to our subsequent collection of receivable balances that were released to us for collection by ReCommunity as a part of the divestiture in the second quarter of fiscal year 2012.

Solid Waste Revenues

• The price change component in Eastern region quarterly solid waste revenue growth period-to-period is the result of $0.4 million from favorable collection pricing, partially offset by $0.1 million from unfavorable disposal pricing. The price change component in Eastern region year-to-date solid waste revenue growth period-to-period is the result of $0.8 million from favorable collection pricing, partially offset by $0.3 million from unfavorable disposal pricing.

• The volume change component in Eastern region quarterly solid waste revenue growth period-to-period is the result of $0.6 million from disposal volume increases, which was driven by a $0.9 million increase in landfill volumes, and $0.1 million from organics and processing volume increases, partially offset by $0.5 million from collection volume decreases. The volume change component in Eastern region year-to-date solid waste revenue growth period-to-period is the result of $4.1 million from disposal volume increases, which was driven by a $4.9 million increase in landfill volumes, and $0.3 million from organics and processing volume increases, partially offset by $2.4 million from collection volume decreases.

• The commodity price and volume change component in Eastern region quarterly solid waste revenue growth period-to-period is the result of $0.9 million from volume increases, which was driven by $0.8 million from organics and processing volume increases, and $0.7 million from favorable pricing, which was driven by $0.4 million in favorable pricing from organics and processing. The commodity price and volume change component in Eastern region year-to-date solid waste revenue growth period-to-period is the result of $1.3 million from favorable pricing, which was primarily due to $1.4 million in favorable pricing from organics and processing, partially offset by $1.0 million from commodity volume decreases, which was driven by $1.6 million from power generation volume decreases.

• The acquisitions and divestitures change component in Eastern region quarterly solid waste revenue growth period-to-period is the result of $2.7 million in increased revenues from acquisitions, $2.2 million of which relates to increased collections revenues, partially offset by $1.5 million in decreased revenues associated with the closure of Maine Energy. The acquisitions and divestitures change component in Eastern region year-to-date solid waste revenue growth period-to-period is the result of $2.7 million in increased revenues from acquisitions, $2.1 million of which relates to increased collections revenues, partially offset by $0.5 million in decreased revenues associated with the closure of Maine Energy.

• The closed landfill change component in Eastern region quarterly and year-to-date total solid waste revenue growth period-to-period is the result of a landfill in the Eastern region that stopped accepting waste in the second quarter of fiscal year 2013 based on meeting its permitted capacity.

49

Eastern region operating loss for the three and nine months ended January 31, 2013 increased by $2.2 million and $4.2 million when compared to the prior fiscal year periods. The increase in operating loss in the three and nine months ended January 31, 2013 is the result of an increase in non-operating expenses associated with severance costs related to the reorganization in the second quarter of fiscal year 2013 and the divestiture of Maine Energy in the three months ended January 31, 2013, divestiture expenses and the loss on divestiture associated with Maine Energy in the three months ended January 31, 2013 and integration and compliance costs associated with the BBI acquisition. Additional operational cost increases include disposal costs, hauling costs, depletion of landfill operating lease obligations, benefit costs associated with health and dental insurance and workers’ compensation insurance and various general and administration costs including bad debt expense and personnel costs. The increase in expenses was partially offset by a decrease in expenses related to host community fees and royalties and cost savings associated with the closure of Maine Energy in the three months ended January 31, 2013. The increase in operating loss for the nine months ended January 31, 2013 is also the result of an increase in expenses associated with other operating and landfill costs and equipment rentals and leases.

Western Region

Our Western region revenues increased $0.4 million, or less than one percent, for the three months ended January 31, 2013 and decreased $7.3 million, or 4.4%, for the nine months ended January 31, 2013, when compared to the prior fiscal year periods.

The price change component in Western region year-to-date solid waste revenue decline period-to-period is the result of $0.6 million from favorable collection pricing, partially offset by $0.2 million from unfavorable disposal pricing at landfills.

• The volume change component in Western region quarterly solid waste revenue growth period-to-period is the result of $1.2 million from disposal volume decreases, of which $1.1 million relates to landfill volumes, and $1.2 million from collection volume decreases, partially offset by a $0.9 million from organics and processing volume increases. The volume change component in Western region year-to-date solid waste revenue decline period-to-period is the result of $7.1 million from disposal volume decreases, of which $6.0 million relates to landfill volumes, and $4.1 million from collection volume decreases, partially offset by $1.4 million from organics and processing volume increases.

Western region operating income for the three and nine months ended January 31, 2013 decreased by $1.0 million and $6.4 million compared to the prior fiscal year periods. The reduction of operating income for the three months ended January 31, 2013 is due to an increase in expenses related to disposal costs, benefit costs associated with health and dental insurance and workers’ compensation, fuel costs, equipment rental and lease costs, depletion of landfill operating lease obligations, leachate disposal costs and depreciation expense, partially offset by a decrease in expenses that include lower purchased material costs, hauling costs and landfill amortization. The decrease in operating income for the nine months ended January 31, 2013 is due to a decrease in revenues, along with an increase in expenses that include disposal costs, benefit costs associated with health and dental insurance, equipment rental and lease costs, vehicle maintenance costs and severance costs related to the reorganization in the second quarter of fiscal year 2013, a decrease in the gain related to the sale of fixed assets, depreciation expense and an increase in bad debt expense, partially offset by a decrease in legal fees, host and royalty fees, outside labor costs, leachate disposal costs, landfill amortization expense, legal settlement costs and various other general and administration expenses associated with the reorganization in the second quarter of fiscal year 2013.

Recycling

Recycling revenues decreased $1.0 million and $8.3 million when comparing the three and nine months ended January 31, 2013 to the prior fiscal year periods driven by $1.2 million and $9.2 million in unfavorable pricing due to declining commodity prices in the marketplace, offset partially by $0.2 million and $0.9 million in volume increases.

Recycling operating income for the three and nine months ended January 31, 2013 decreased by $0.6 million and $5.3 million compared to the prior fiscal year periods due primarily to revenue decline associated with unfavorable commodity prices, partially offset by decreased operating expenses related to a reduction in recycled material costs.

Other

Other revenues decreased $0.6 million and $2.0 million when comparing the three and nine months ended January 31, 2013 to the prior fiscal year periods driven by volume declines from major customer accounts, offset partially by volume increases from transportation.

Other operating loss for the three months ended January 31, 2013 increased by $0.6 million when compared to the prior fiscal year period as the reduction in revenues, increased severance costs associated with the reorganization of senior management and increased equity compensation costs, were partially offset by a reduction in expenses related to hauling costs, fuel costs and vehicle maintenance costs and labor, benefits and other personnel costs associated with the head count reduction that took place as a part of the reorganization in the second quarter of fiscal year 2013. Other operating loss for the nine months ended January 31, 2013 increased by $0.3 million compared to the prior fiscal year period due primarily to an increase in equity compensation expense and additional severance costs associated with the reorganization of senior management in the three months ended January 31, 2013, partially offset by a reduction in expenses related to benefits and other personnel costs associated with the head count reduction that took place as a part of the reorganization in the second quarter of fiscal year 2013.

Liquidity and Capital Resources

Our business is capital intensive. Our capital requirements include acquisitions, fixed asset purchases and capital expenditures for landfill development and cell construction, as well as site and cell closure. Our capital expenditures are broadly defined as pertaining to growth, maintenance or acquisition activities. Growth capital expenditures are defined as costs related to development of new airspace, permit expansions and new recycling contracts along with incremental costs of equipment and infrastructure added to further such activities. Growth capital expenditures include the cost of equipment added directly as a result of organic business growth, as well as expenditures associated with building infrastructure to increase throughput at transfer stations and recycling facilities. Growth capital expenditures also include those outlays associated with acquiring landfill operating leases, which do not meet the operating lease payment definition, but which were included as a commitment in the successful bid. Maintenance capital expenditures are defined as landfill cell construction costs not related to expansion airspace, costs for normal permit renewals and replacement costs for equipment due to age or obsolescence. Acquisition capital expenditures are defined as costs of equipment added directly as a result of new business growth related to an acquisition.

We had a net working capital deficit of $29.9 million at January 31, 2013 compared to a deficit of $25.5 million at April 30, 2012. Net working capital comprises current assets, excluding cash and cash equivalents, minus current liabilities. The $4.4 million decline in net working capital relates primarily to higher other accrued liabilities, which increased by $6.4 million due

51

largely to additional costs related to the Maine Energy divestiture, higher accrued interest, which increased by $2.9 million due largely to the timing of interest payments associated with the 2019 Notes, and higher accounts payable, which increased by $1.0 million due largely to timing and additional payables acquired through the BBI acquisition. This was partially offset by higher accounts receivable, which increased by $3.0 million due largely to additional receivable balances associated with the BBI acquisition and decreased collectability, and higher prepaid expenses, which increased by $2.9 million due largely to timing.

On October 3, 2012, as a part of a registered public offering we sold 11.5 million shares of Class A common stock at an average price of $4.00 per share. The net proceeds received from the registered public offering, after deducting underwriting discounts, commissions and offering expenses, were $42.2 million and were used to refinance our Second Lien Notes and pay down 2011 Revolver borrowings.

Outstanding Long-Term Debt

2011 Senior Secured Revolving Credit Facility. The 2011 Revolver is a $227.5 million revolving credit and letter of credit facility due March 18, 2016 (the “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. We entered into a second amendment and consent under our Senior Credit Facility on September 20, 2012. The amendment provided us the ability to redeem our Second Lien Notes and adjusted our financial covenants, which become more restrictive over the term of the Senior Credit Facility.

The Senior Credit Facility, as amended, is subject to customary affirmative, negative and financial covenants. As of January 31, 2013, these covenants restricted fiscal year capital expenditures to 1.5 times our consolidated depreciation expenses, depletion expenses and landfill amortization expenses, set a minimum interest coverage ratio of 2.00, a maximum consolidated total funded debt to consolidated EBITDA ratio of 5.75 and a maximum senior funded debt to consolidated EBITDA ratio of 2.75. In addition to the financial covenants described above, the Senior Credit Facility, as amended, also contains a number of important 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 January 31, 2013, we were in compliance with all covenants under the indenture governing the Senior Credit Facility 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.

As of January 31, 2013, we were in compliance with all financial covenants contained in the 2011 Revolver as follows:

			Covenant
	Twelve Months Ended		Requirements at
Senior Secured Credit Facility Covenant	January 31, 2013		January 31, 2013
Total funded debt / Bank-defined cash flow metric (1)		5.23		5.75 Max.
Senior funded debt / Bank-defined cash flow metric (1)		1.81		2.75 Max.
Interest coverage		2.24		2.00 Min.

(1) Bank-defined cash flow metric is based on operating results for the twelve months preceding the measurement date, January 31, 2013. A reconciliation of net cash provided by operating activities to bank-defined cash flow metric is as follows (in millions):

Further advances were available under the 2011 Revolver in the amount of $56.1 million as of January 31, 2013. The available amount is net of outstanding irrevocable letters of credit totaling $29.7 million as of January 31, 2013, at which date no amount had been drawn.

2019 Notes. As of January 31, 2013, we had outstanding $325.0 million aggregate principal amount of the senior subordinated notes due February 15, 2019 (the “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.

On October 9 2012, we completed the offering of an additional $125.0 million aggregate principal amount of 2019 Notes. The 2019 Notes were issued at a discount of $1.9 million, which is amortized to interest expense over the life of the 2019 Notes commencing February 15, 2013. The net proceeds from the offering of additional 2019 Notes were used to pay for the early tender of our Second Lien Notes and, together with $50.0 million of 2011 Revolver borrowings, $42.2 million of net equity proceeds from the registered public offering and sale of Class A common stock referenced above and other available funds, to redeem our remaining Second Lien Notes and to pay related transaction costs.

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 January 31, 2013, 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 the Senior Credit Facility and Second Lien Notes.

Second Lien Notes. As of January 31, 2013, we did not have any aggregate principal amount of Second Lien Notes outstanding. We initiated a cash tender and consent solicitation on September 24, 2012 for our then outstanding $180.0 million Second Lien Notes (the “Tender Offer”). On October 9, 2012 we repurchased $107.3 million of our then outstanding Second Lien Notes through the Tender Offer. Holders who tendered the Second Lien Notes prior to the early tender date received $1,060 for each $1,000 in principal amount of Second Lien Notes repurchased, which included an early tender premium of $30 per $1,000 in principal amount of Second Lien Notes, plus accrued and unpaid interest to, but not including the early tender offer settlement date. On November 8, 2012, we repurchased the remaining $72.7 million aggregate principal amount of our then outstanding Second Lien Notes. The remaining holders who tendered the Second Lien Notes received $1,055 for each $1,000 in principal amount of Second Lien Notes repurchased, plus accrued and unpaid interest to, but not including the redemption date.

53

Maine Bonds. On December 28, 2005, we completed a $25.0 million financing transaction involving the issuance by the Authority of $25.0 million aggregate principal amount of its Solid Waste Disposal Revenue Bonds Series 2005R-1 (the “Bonds”). The Bonds were issued pursuant to an indenture, dated as of December 1, 2005 and were enhanced by an irrevocable, transferable direct-pay letter of credit issued by Bank of America, N.A. Pursuant to a Financing Agreement, dated as of December 1, 2005, by and between us and the Authority, we have borrowed the proceeds of the Bonds to pay for certain costs relating to landfill development and construction, vehicle, container and related equipment acquisition for solid waste collection and transportation services, improvements to existing solid waste disposal, hauling, transfer station and other facilities, other infrastructure improvements, and machinery and equipment for solid waste disposal operations owned and operated by us, or a related party, all located in Maine.

On February 1, 2012, we converted the interest rate period on, and remarketed, $21.4 million aggregate principal amount of the original $25.0 million Bonds. The mandatorily tendered Bonds were converted from a variable rate to a five year fixed term interest rate of 6.25% per annum and included additional covenants and credit support for the benefit of the holders of those Converted Bonds, including guarantees by certain of our subsidiaries. The Converted Bonds are no longer secured by a letter of credit issued by a bank. The remaining $3.6 million aggregate principal amount of outstanding Bonds remain as variable rate bonds secured by a letter of credit issued by a bank. The Bonds and Converted Bonds mature on January 1, 2025.

Summary of Cash Flow Activity

The following table summarizes our cash flows for the nine months ended January 31, 2013 and 2012, respectively (in millions):

	Nine Months Ended
	January 31,
	2013			2012
Net cash provided by operating activities	$	30.5		$	49.7
Net cash used in investing activities	$	(76.1	)	$	(60.2	)
Net cash provided by financing activities	$	42.2		$	9.1

Net cash flows provided by operating activities. Net cash flows provided by operating activities decreased by $19.2 million from the nine months ended January 31, 2012. The most significant items affecting the change in our operating cash flows are summarized below:

• Loss from continuing operations. Our loss from continuing operations increased $11.7 million to $40.9 million for the nine months ended January 31, 2013 from $29.2 million for the nine months ended January 31, 2012. The loss was driven primarily by our operational performance as revenues decreased $15.1 million from the nine months ended January 31, 2012, while cost of operations, $1.2 million, severance and reorganization costs, $3.5 million, and expense from divestiture, acquisition and financing costs, $1.0 million, all increased. We did experience a cost savings within general and administration of $2.4 million from the nine months ended January 31, 2012, but this reduction was not able to compensate for the previously mentioned items, resulting in decreased cash flows from operations.

• Changes in assets and liabilities, net of effects from business acquisitions and divestitures. Our cash flow from operations was unfavorably impacted in the amount of $3.0 million in the nine months ended January 31, 2013 by changes in our assets and liabilities. This change was driven by unfavorable impacts related to our accounts receivable, which is affected by both revenue changes and timing of payments received, accrued expenses and other liabilities, which is affected primarily by cost changes such as interest, the timing of payments, and changes related to accrued capping, closure, and post closure costs, prepaid expenses, inventories and other assets, which is affected primarily by the timing of payments, expense recognition, as well as cost changes, and accounts payable, which is affected by both cost changes and timing of payments. This is compared to the nine months ended January 31, 2012, when our cash flow from operations was favorably impacted $2.0 million by changes in our assets and liabilities. The unfavorable change of $5.0 million was due primarily to the unfavorable $8.4 million impact associated with accounts receivable and the unfavorable $2.8 million impact associated with accounts payable, partially offset by the favorable $6.2 million impact of accrued expenses and other liabilities.

Net cash used in investing activities. Net cash used in investing activities increased $15.9 million from the nine months ended January 31, 2012. The most significant items affecting the change in our investing cash flows are summarized below:

• Acquisitions, net of cash acquired. During the nine months ended January 31, 2013, we acquired four solid waste hauling operations in the Western region for total consideration of $5.4 million, of which we paid $4.9 million in cash. We also acquired all of the outstanding capital stock of BBI in the Eastern region for total consideration of $22.6 million, of which we paid $20.0 million in cash. In the nine months ended January 31, 2012 we acquired five solid waste hauling operations and completed the acquisition of McKean County landfill business in Pennsylvania for total consideration of $2.3 million, of which we paid $2.1 million in cash.

• Investments in unconsolidated entities. During the nine months ended January 31, 2013, we made investments to unconsolidated entities totaling $1.0 million compared to $4.2 million in the nine months ended January 31, 2012.

• Capital expenditures. Lower capital expenditures by $4.8 million in the nine months ended January 31, 2013 related primarily to the timing of projects and a decrease in spending related to the closure of Maine Energy, our waste-to-energy facility.

Net cash provided by financing activities. Net cash provided by financing activities increased $33.1 million from the nine months ended January 31, 2012. The most significant items affecting the change in our financing cash flows are summarized below:

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

• Debt activity. Increased debt borrowings by $206.6 million associated primarily with the offering of $125.0 million in additional 2019 Notes and additional 2011 Revolver borrowings. This more than offset the $201.1 million in increased debt payments associated primarily with the full redemption of the Second Lien Notes.

• Tender premium and costs. A tender premium and tender costs of $10.7 million was paid as a part of the redemption of the Second Lien Notes.

We generally meet liquidity needs from operating cash flow and the 2011 Revolver. These liquidity needs are primarily for capital expenditures for vehicles, containers and landfill development, debt service costs and capping, closure and post-closure expenditures and acquisitions.

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 previously being used to hedge the interest rate risk associated with the forecasted financing transaction to redeem our 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.

We dedesignated both of the $75.0 million forward starting interest rate derivative agreements and discontinued hedge accounting in accordance with ASC 815-30 during the second quarter of fiscal year 2013 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 the second quarter of fiscal year 2013.

We 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 January 31, 2013, 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.

We have filed a universal shelf registration statement with the Securities and Exchange Commission (the “SEC”) pursuant to which we may from time to time issue securities in an amount of up to $250.0 million. Following the stock sale in October 2012, an aggregate of $204.0 million remains available for issuance under the shelf registration statement. 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 such securities on favorable terms, if at all.

55

Inflation and Prevailing Economic Conditions

To date, inflation 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, including increases in landfill tipping fees and, in some cases, fuel costs. We have implemented a fuel surcharge program, 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.

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

Limitations on Ownership of Notes

Pursuant to Section 2.19 of the indenture governing the 2019 Notes and the provisions of the Converted Bonds, no beneficial holder of the 2019 Notes and/or Converted Bonds is permitted to knowingly acquire 2019 Notes and/or Converted Bonds if such person would own 10% or more of the consolidated debt for which relevant subsidiaries of ours are obligated (and must dispose of 2019 Notes and Converted 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 and Converted 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 January 31, 2013, that dollar amount was $48.8 million.

Critical Accounting Policies and Estimates

The preparation of our unaudited consolidated 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 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 assumptions which are based on historical experience and on various other factors that are believed to be reasonable under the circumstances. The results of its 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, 2012.

Adoption of New Accounting Pronouncements

For a description of the new accounting standards adopted that may affect us, see Note 1 to our unaudited 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 $145.3 million of long-term debt at January 31, 2013. The weighted average interest rate on the variable rate portion of long-term debt was approximately 4.0% at January 31, 2013. Should the average interest rate on the variable rate portion of long-term debt change by 100 basis points, it would have an approximate interest expense change of $0.4 million for the quarter reported.

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

56

We are currently party to two forward starting interest rate derivative agreements that were previously being used to hedge the interest rate risk associated with the forecasted financing transaction to redeem our 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.

We dedesignated both of the $75.0 million forward starting interest rate derivative agreements and discontinued hedge accounting in accordance with ASC 815-30 during the second quarter of fiscal year 2013 because the interest payments associated with that portion of 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 the second quarter of fiscal year 2013.

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 January 31, 2013, 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% in the quarter ended January 31, 2013, management’s estimate of the impact on our operating income for such quarter is approximately $0.4 million. Our sensitivity to changes in commodity prices is complex because each customer contract is unique relative to revenue sharing, tipping or processing fees and other arrangements. The above estimated ranges of operating income impact may not be indicative of future operating results and actual results may vary materially.

ITEM 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 January 31, 2013. 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, 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 January 31, 2013, 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. 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 fiscal quarter ended January 31, 2013 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

57

PART II. OTHER INFORMATION

ITEM 1. 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 the waste management business.

In accordance with 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 ASC 450-20-25-2. In instances where we determine that a loss is probable and we can reasonably estimate a range of losses 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 450-20-25-3. As of January 31, 2013, there were no accruals established related to our outstanding legal proceedings.

We offer no prediction of the outcome of any of the proceedings or negotiations described below. We are vigorously defending each of the unresolved lawsuits and claims described below. However, litigation is subject to inherent uncertainty and there can be no guarantee we will prevail or that any judgments against us, if sustained on appeal, will not have a material adverse effect on our business, financial condition, results of operations or cash flows.

Penobscot Energy Recovery Company Matter

On May 31, 2011, we received formal written notice from the Penobscot Energy Recovery Company (“PERC”) submitting to arbitration what it alleges is a disputed invoice in the amount of approximately $3.2 million dated March 2, 2011. PERC contended that Pine Tree Waste, Inc., our subsidiary, failed since 2001 to honor a “put-or-pay” waste disposal arrangement. Arbitration of this matter was initiated, but in January 2012 a global settlement was reached in principle and memorialized in a letter of intent dated February 1, 2012, which documented the final terms of the settlement and dismissal of the arbitration action. The final global settlement documents were executed effective October 1, 2012. Pursuant to the terms of the settlement we will not be required to make a cash payout. We anticipate that there may be nonmaterial incremental operational expenses that arise from implementing the terms of the settlement with regard to waste deliveries.

New York State Tax Litigation Matter

On January 18, 2011, certain of our subsidiaries doing business in New York State received a Notice of Deficiency from the New York State Department of Taxation and Finance asserting liability for corporation franchise tax for one or more of the tax years ended April 30, 2004 through April 30, 2006. The Notices, in the aggregate, assert liability of $3.9 million, comprising $2.2 million of tax and $1.7 million of penalties and interest. New York State has alleged that we are not permitted to file a single combined corporation franchise tax return with our subsidiaries for each of the years audited.

We filed Petitions for Redetermination (“Petitions”) with the State of New York Division of Tax Appeals on April 13-14, 2011, and an administrative hearing before a single tax tribunal administrative law judge on all Petitions that was scheduled for December 12, 2012 has been rescheduled to April 17-19, 2013. We expect to aggressively defend against this claim through the administrative adjudication and appeals process and the courts, if necessary. Under ASC 740, we believe our position will more likely than not be successful in contesting the deficiencies and consequently, we have not established any reserve for this matter.

Environmental 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 existing 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.

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, including the preparation of a Remedial Investigation and Feasibility Study (the “Study”). A draft of the Study was submitted to DEC in January 2009 (followed by a final report in May 2009). The Study estimated that the undiscounted costs associated with implementing the preferred

58

remedies will be approximately $10.2 million and it is unlikely that any costs relating to onsite remediation will be incurred until fiscal year 2014. On February 28, 2011, the DEC issued a Proposal 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. A new Order on Consent and Administrative Settlement naming WSI and NiMo as Respondents was received by us on November 13, 2012, requiring that we enter into a Consent Order with DEC within 60 days and mandating implementation of the ROD. The deadline for execution of the Consent Order has recently been extended until March 27, 2013.

WSI is jointly and severally liable for the total cost to remediate and we initially expected to be responsible for approximately 30% upon implementation of a cost-sharing agreement with NiMo and GM. Based on these estimates, we recorded an environmental remediation charge of $2.8 million in the third quarter of fiscal year 2009. In fiscal year 2009, we recognized an additional charge of $1.5 million, representing an additional 15% of the estimated costs, in recognition of the deteriorating financial condition and eventual bankruptcy filing of GM. In fiscal year 2010, we recognized an additional charge of $0.3 million based on changes in the expected timing of cash outflows. Based on the estimated costs in the ROD, and changes in the estimated timing of cash flows, we recorded an environmental remediation charge of $0.5 million in fiscal year 2011. Such charges could be significantly higher if costs exceed estimates. We inflate these estimated costs in current dollars until the expected time of payment and discount the cost to present value using a risk free interest rate (2.7%). At January 31, 2013 and April 30, 2012, we have recorded liabilities of $5.3 million and $5.2 million, respectively, including the recognition of thirty-four thousand dollars and $0.1 million dollars of accretion expense in the in the three and nine months ended January 31, 2013 and 2012, respectively.

In September 2011, the DEC settled its environmental claim against the estate of the former GM (known as the “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. We expect the warrants to be issued in fiscal year 2013. We have not assumed that the payment of these claims will reduce our exposure.

ITEM 1A. RISK FACTORS

Our business is subject to a number of risks, including those identified in Item 1A, “Risk Factors” of our 2012 Annual Report on Form 10-K for the year ended April 30, 2012, 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 of January 31, 2013, 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, 2012 and in our Current Report on Form 8-K filed with the SEC on September 24, 2012. We may disclose additional changes to our risk factors or disclose additional factors from time to time in our future filings with the SEC.

As of January 31, 2013, these covenants restrict fiscal year capital expenditures to 1.5 times our consolidated depreciation expenses, depletion expenses and landfill amortization expenses, set a minimum interest coverage ratio of 2.00, a maximum consolidated total funded debt to consolidated EBITDA ratio of 5.75 and a maximum senior funded debt to consolidated EBITDA ratio of 2.75. In addition to the financial covenants described above, the Senior Credit Facility, as amended, also contains a number of important negative covenants which restrict, among other things, our ability to sell assets, pay dividends, repurchase stock, incur debt, grant liens and issue preferred stock. As of January 31, 2013, we were in compliance with all covenants under the indenture governing the Senior Credit Facility 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 third parties, including the joint ventures to which we are already party to.

DIVESTITURE AND DISCONTINUED OPERATIONS

13. DIVESTITURE AND DISCONTINUED OPERATIONS

Maine Energy Divestiture

On August 1, 2012, we executed a purchase and sale agreement with the City of Biddeford, Maine pursuant to which we agreed to sell the real property of Maine Energy, which is located in our Eastern region, to the City of Biddeford, subject to satisfaction of conditions precedent and closing. We agreed to sell Maine Energy for undiscounted purchase consideration of $6,650, which shall be paid to us in equal installments over the next 21 years, subject to the terms of the purchase and sale agreement. The transaction closed on November 30, 2012, and we waived certain conditions precedent not satisfied at that time. Effective December 31, 2012, we closed the facility and initiated the decommissioning process in accordance with the provisions of the agreement. Following the decommissioning of Maine Energy, it is our responsibility to demolish the facility, at our cost, within twelve months of the closing date and in accordance with the terms of the purchase and sale agreement. We recorded a charge to loss on divestiture of $353 in the three months ended January 31, 2013 as a result of this transaction.

As a part of the closure and decommissioning of Maine Energy, we are withdrawing from a multiemployer pension plan that we have made contributions to for the benefit of Maine Energy employees covered under a collective bargaining agreement. We have a potential liability associated with our withdrawal from the multiemployer pension plan based on the value of the plan’s unfunded vested benefits. In accordance with ASC 715-80, in a situation with unfunded vested benefits, a liability is not recorded by a participating employer as no single employer has an identifiable share of the actuarial obligation of the multiemployer pension plan.

In accordance with ASC 450-20, we accrue for an obligation when an obligation becomes probable and reasonably estimable. We currently believe that an obligation associated with withdrawal from the multiemployer pension plan is probable, but we cannot reasonably estimate the amount of loss or possible range of loss due to a lack of information being made available by the fund administrator in regards to the unfunded vested benefits. The fund administrator will quantify our withdrawal liability based on the unfunded vested benefits as of the plan year preceding actual withdrawal. As we expect to completely withdraw from the plan in early fiscal year 2014, we expect the plan administrator to base our obligation on the plan year ended January 31, 2013. We expect to record an obligation associated with our portion of unfunded vested benefits in fiscal year 2014. As of January 31, 2013, no accrual is established related to withdrawal from the multiemployer pension plan.

Discontinued Operations

On January 23, 2011, we entered into a purchase and sale agreement and related agreements to sell non-integrated recycling assets and select intellectual property assets to a new company (the “Purchaser”) formed by Pegasus Capital Advisors, L.P. and Intersection LLC. Pursuant to these agreements, we divested non-integrated recycling assets located outside our core operating regions of New York, Massachusetts, Vermont, New Hampshire, Maine and northern Pennsylvania, including 17 material recovery facilities (“MRFs”), one transfer station and certain related intellectual property assets. Following the transaction, we retained four integrated MRFs located in our core operating regions. As a part of the disposition, we also entered into a ten-year commodities marketing agreement with the Purchaser to market 100% of the tonnage from three of our remaining integrated MRFs.

We completed the transaction on March 1, 2011 for $134,195 in gross cash proceeds. This included an estimated $3,795 working capital and other purchase price adjustment, which was subject to further adjustment, as defined in the purchase and sale agreement. The final working capital adjustment, along with additional legal expenses related to the transaction, of $646 was recorded to gain on disposal of discontinued operations, net of income taxes in the first quarter of fiscal year 2012.

In the second quarter of fiscal year 2012, we recorded an additional working capital adjustment of $79 to gain on disposal of discontinued operations, net of income taxes, which related to our subsequent collection of receivable balances that were released to us for collection by the Purchaser.

INVESTMENTS IN UNCONSOLIDATED ENTITIES

15. INVESTMENTS IN UNCONSOLIDATED ENTITIES

Equity Method Investments

GreenFiber. We entered into a joint venture agreement in July 2000 with Louisiana-Pacific Corporation (“LP”) to combine our respective cellulose insulation businesses into a single operating entity, US GreenFiber LLC (“GreenFiber”). We account for our 50% membership interest in GreenFiber using the equity method of accounting.

In April 2011, we issued a guaranty in support of GreenFiber’s amended and restated loan and security agreement. The guaranty can be drawn on upon an event of default and remains in place through December 1, 2014, the extended term of GreenFiber’s modified and restated loan and security agreement. Our guaranty associated with the credit facility is $2,200 as of January 31, 2013. The fair value of our guaranty as of January 31, 2013, which is recorded in other long-term liabilities, is $264.

As of December 31, 2011, GreenFiber performed a test for goodwill impairment. The goodwill impairment analysis indicated that the carrying value of their reporting unit exceeded the fair value of their reporting unit, and GreenFiber determined that the entire amount of their goodwill was impaired. Consequently, we recorded our portion of the goodwill impairment charge of $5,090 as a part of the loss on equity method investment in the third quarter of fiscal year 2012.

Based on the analysis performed, we determined that the current book value of our investment in GreenFiber at that time exceeded its fair value. The analysis calculated GreenFiber’s fair value based on the income approach using discounted cash flows taking into account current expectations for asset utilization, housing starts and the remaining useful life of related assets. We recorded a charge of $10,680 as an impairment on equity method investment in the third quarter of fiscal year 2012.

In May 2012, we and LP made identical commitments to fund any liquidity shortfalls of GreenFiber related to covenant compliance as defined in and through the term of GreenFiber’s modified and restated loan and security agreement. Based on the terms of this agreement, in May 2012, we and LP made identical equity contributions to GreenFiber of $500 to cure such shortfall.

Our investment in GreenFiber amounted to $2,638 and $6,502 at January 31, 2013 and April 30, 2012, respectively. Summarized financial information for GreenFiber is as follows:

Tompkins. In May 2011, we finalized the terms of a joint venture agreement with FCR, LLC (“FCR”) to form Tompkins County Recycling LLC (“Tompkins”), a joint venture that operates a MRF located in Tompkins County, NY and processes and sells commodities delivered to the Tompkins MRF. In connection with the formation of the joint venture, we acquired a 50% membership interest in Tompkins in exchange for an initial cash contribution to Tompkins of $285. FCR made an initial cash contribution of $285 as well, and acquired a 50% membership interest in Tompkins. Income and losses are allocated to members based on membership interest percentage. Our investment in Tompkins amounted to $307 and $292 at January 31, 2013 and April 30, 2012, respectively. We account for our 50% membership interest in Tompkins using the equity method of accounting.

Cost Method Investments

Evergreen. Our investment and ownership interest in Evergreen National Indemnity Company, a surety company which provides surety bonds to us and other parties, amounted to $10,657 and 19.9%, as of January 31, 2013 and April 30, 2012.

RecycleRewards. Our investment and ownership interest in RecycleRewards, Inc., a company that markets an incentive based recycling service, amounted to $4,479 and 6.0% as of January 31, 2013 and $4,479 and 6.2% as of April 30, 2012.

AGreen. In May 2011, we entered into a renewable energy project operating agreement with AGreen Energy LLC (“AGreen”). As a part of the agreement, we provide certain operation, maintenance and administrative services, as well as procure organic materials that would otherwise be disposed of to small farm-based biogas renewable energy projects that produce renewable energy and other valuable products and services. Our investment and membership interest in AGreen amounted to $350 and 11.9% as of January 31, 2013 and April 30, 2012.

GreenerU . In March 2012, we entered into a strategic partnership agreement with GreenerU, Inc. (“GreenerU”), a company that delivers energy and sustainability solutions to the college, university and preparatory school markets in order to reduce their energy costs and carbon emissions through the formulation of programs and policies and the running of renewable energy projects. As a part of the agreement, we work with GreenerU to formulate compelling offers and approaches for colleges, universities and preparatory schools in the area of waste, recycling, energy, composting, resource conservation and other appropriate sustainability initiatives. In the first quarter of fiscal year 2013, we made a $500 investment in GreenerU through the purchase of preferred stock, bringing our investment and ownership interest in GreenerU to $1,000 and 6.3% as of January 31, 2013. Our investment and ownership interest in GreenerU was $500 and 4.2% as of April 30, 2012.

FAIR VALUE OF FINANCIAL INSTRUMENTS

9 Months Ended

Jan. 31, 2013

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.

Our financial instruments include cash and cash equivalents, trade receivables, restricted trust and escrow accounts, commodity and interest rate derivatives, trade payables and long-term debt. The carrying values of cash and cash equivalents, trade receivables and trade payables approximate their respective fair values. At January 31, 2013, the fair value of our fixed rate debt, including the 2019 Notes and the Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-2 due January 1, 2025 (the “Converted Bonds”) was approximately $342,349 and the carrying value was $344,608. 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 Converted 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 the Converted Bonds or securities with similar characteristics. As of January 31, 2013, the fair value of the 2011 Revolver approximated its carrying value of $141,700 based on current borrowing rates for similar types of borrowing arrangements.

As of January 31, 2013 our assets and liabilities that are measured at fair value on a recurring basis included the following:

	Fair Value Measurement at January 31, 2013 Using:
	Quoted Prices in
	Active Markets for		Significant Other		Significant
	Identical Assets		Observable Inputs		Unobservable Inputs
	(Level 1)		(Level 2)		(Level 3)
Assets:
Restricted assets	$	523	$	—	$	—
Liabilities:
Interest rate derivatives	$	—	$	3,871	$	—

As of April 30, 2012 our assets and liabilities that are measured at fair value on a recurring basis included the following:

	Fair Value Measurement at April 30, 2012 Using:
	Quoted Prices in
	Active Markets for		Significant Other		Significant
	Identical Assets		Observable Inputs		Unobservable Inputs
	(Level 1)		(Level 2)		(Level 3)
Assets:
Restricted assets	$	424	$	—	$	—
Liabilities:
Interest rate derivatives	$	—	$	2,369	$	—

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 to hedge the interest rate risk associated with the forecasted financing transaction to redeem our Second Lien Notes effective January 15, 2013. The total notional amount of these agreements is $150,000 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.

For interest rate derivatives deemed to be effective cash flow hedges, the change in fair value is recorded in our stockholders’ equity as a component of accumulated other comprehensive loss and included in interest expense at the same time as interest expense is affected by the hedged transaction. Differences paid or received over the life of the agreements are recorded as additions to or reductions of interest expense of the underlying debt. For interest rate derivatives deemed to be ineffective cash flow hedges, the change in fair value is recorded through earnings and included in (gain) loss on derivative instruments.

We dedesignated both of the $75,000 forward starting interest rate derivative agreements and discontinued hedge accounting in accordance with ASC 815-30 in the second quarter of fiscal year 2013 because the interest payments associated with the forecasted financing transaction were no longer deemed probable due to the redemption of our Second Lien Notes as discussed in Note 5. We recognized a $3,626 loss, reclassified from accumulated other comprehensive loss, as a loss on derivative instruments in the second quarter of fiscal year 2013.

The fair values of the interest rate derivatives are obtained from third-party counter-parties and adjusted based on the credit risk of our counter-parties and us. We recognize all derivatives on the balance sheet at fair value.

BUSINESS ACQUISITIONS

2. BUSINESS ACQUISITIONS

During the nine months ended January 31, 2013, we acquired four solid waste hauling operations in the Western region for total consideration of $5,384, including $4,854 in cash and $530 in holdbacks to the sellers, and all of the outstanding capital stock of Bestway Disposal Services and BBI Waste Services (“BBI”) in the Eastern region for total consideration, subject to certain closing adjustments based on the terms of the agreement, of $22,650, including $20,000 in cash and 625 shares of our Class A common stock, valued at an aggregate of $2,650. We recorded an additional $5,242 to goodwill for the increased deferred tax liability related to the BBI acquisition based on the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for income tax purposes, see Note 10 for further discussion. The acquisition of BBI, a provider of solid waste collection, transfer and liquid waste services in New Hampshire and Maine, on December 6, 2012 provides us the opportunity to internalize additional waste and recyclables and to consolidate operations, routes and transportation within the Eastern region. Revenue generated from BBI amounted to $2,924 from December 6, 2012 to January 31, 2013. During the nine months ended January 31, 2012, we acquired five solid waste hauling operations and completed the acquisition of the McKean County landfill business in Pennsylvania, by acquiring additional equipment not included in the original acquisition, for total consideration of $2,284, including $2,102 in cash and $182 in holdbacks to the sellers.

The operating results of these businesses are included in the accompanying unaudited consolidated statements of operations from the dates of acquisition, and the purchase prices have been allocated to the net assets acquired based on fair values at the dates of acquisition, with the residual amounts recorded as goodwill. Acquired intangible assets other than goodwill that are subject to amortization include client lists and non-compete covenants. These are amortized over a five to ten year period from the date of acquisition. All amounts recorded to goodwill are expected to be deductible for tax purposes, except for $8,078 of the current year goodwill related to the BBI acquisition. The purchase price allocated to net assets acquired and the residual amount allocated to goodwill during the nine months ended January 31, 2013 and 2012 are as follows:

	January 31,
	2013 (1)			2012
Equipment	$	9,403		$	605
Goodwill		14,575			569
Intangible assets		9,601			1,136
Current assets		1,475			—
Current liabilities		(7,118	)		(26	)
Total	$	27,936		$	2,284

1) The purchase price allocated to net assets acquired and the residual amount allocated to goodwill associated with the BBI acquisition has not been finalized and is provisional in nature. Management’s estimates and assumptions are subject to change upon finalization of the valuation and may be adjusted in accordance with ASC 805.

SEGMENT REPORTING

14. 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 are derived mainly from collection, transfer, disposal, landfill, landfill-gas-to energy, recycling and organic 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. Ancillary operations, major customer accounts, discontinued operations, and earnings from equity method investees are included in our “Other” reportable segment. Segment data for the three and nine months ended January 31, 2012 has been revised to properly align with internal management reporting.

INCOME TAXES

10. INCOME TAXES

The benefit for income taxes for the three and nine months ended January 31, 2013 includes a $5,242 deferred tax benefit due to a reduction of the valuation allowance. In determining the need for a valuation allowance, we have assessed the available means of recovering deferred tax assets, including the existence of reversing temporary differences. The valuation allowance decreased due to the recognition of additional reversing temporary differences from the $5,242 deferred tax liability recorded through goodwill related to the BBI acquisition. The $5,242 deferred tax liability related to the BBI acquisition was based on the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for income tax purposes. The remaining portion of the $3,899 benefit for income taxes for the nine months ending January 31, 2013 and the $1,330 provision for income taxes for the nine months ending January 31, 2012 include $1,176 and $1,085 deferred tax provisions, respectively, due mainly to the increase in the deferred tax liability for indefinite lived assets and a $167 and $245 current tax provision, respectively. 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.

(a) 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 the waste management business.

In accordance with 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 ASC 450-20-25-2. In instances where we determine that a loss is probable and we can reasonably estimate a range of losses 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 450-20-25-3. As of January 31, 2013, there were no accruals established related to our outstanding legal proceedings.

We offer no prediction of the outcome of any of the proceedings or negotiations described below. We are vigorously defending each of the unresolved lawsuits and claims described below. However, litigation is subject to inherent uncertainty and there can be no guarantee we will prevail or that any judgments against us, if sustained on appeal, will not have a material adverse effect on our business, financial condition, results of operations or cash flows.

Penobscot Energy Recovery Company Matter

On May 31, 2011, we received formal written notice from the Penobscot Energy Recovery Company (“PERC”) submitting to arbitration what it alleges is a disputed invoice in the amount of approximately $3,195 dated March 2, 2011. PERC contended that Pine Tree Waste, Inc., our subsidiary, failed since 2001 to honor a “put-or-pay” waste disposal arrangement. Arbitration of this matter was initiated, but in January 2012 a global settlement was reached in principle and memorialized in a letter of intent dated February 1, 2012, which documented the final terms of the settlement and dismissal of the arbitration action. The final global settlement documents were executed effective October 1, 2012. Pursuant to the terms of the settlement, we will not be required to make a cash payout. We anticipate that there may be nonmaterial incremental operational expenses that arise from implementing the terms of the settlement with regard to waste deliveries.

New York State Tax Litigation Matter

On January 18, 2011, certain of our subsidiaries doing business in New York State received a Notice of Deficiency (the “Notices”) from the New York State Department of Taxation and Finance asserting liability for corporation franchise tax for one or more of the tax years ended April 30, 2004 through April 30, 2006. The Notices, in the aggregate, assert liability of $3,852, comprising $2,220 of tax and $1,632 of penalties and interest. New York State has alleged that we are not permitted to file a single combined corporation franchise tax return with our subsidiaries for each of the years audited.

We filed Petitions for Redetermination (“Petitions”) with the State of New York Division of Tax Appeals on April 13-14, 2011, and an administrative hearing before a single tax tribunal administrative law judge on all Petitions that was scheduled for December 12, 2012 has been rescheduled to April 17-19, 2013. We expect to aggressively defend against this claim through the administrative adjudication and appeals process and the courts, if necessary. Under ASC 740, we believe our position will more likely than not be successful in contesting the deficiencies and consequently, we have not established any reserve for this matter.

(b) Environmental 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 existing 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.

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, including the preparation of a Remedial Investigation and Feasibility Study (the “Study”). A draft of the Study was submitted to 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 will be approximately $10,219 and it is unlikely that any costs relating to onsite remediation will be incurred until fiscal year 2014. On February 28, 2011, the DEC issued a Proposal 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. A new Order on Consent and Administrative Settlement naming WSI and NiMo as Respondents was received by us on November 13, 2012, requiring that we enter into a Consent Order with DEC within 60 days and mandating implementation of the ROD. The deadline for execution of the Consent Order has recently been extended until March 27, 2013.

WSI is jointly and severally liable for the total cost to remediate and we initially expected to be responsible for approximately 30% upon implementation of a cost-sharing agreement with NiMo and GM. Based on these estimates, we recorded an environmental remediation charge of $2,823 in the third quarter of fiscal year 2009. In the fourth quarter of fiscal year 2009, we recognized an additional charge of $1,532, representing an additional 15% of the estimated costs, in recognition of the deteriorating financial condition and eventual bankruptcy filing of GM. In the fourth quarter of fiscal year 2010, we recognized an additional charge of $335 based on changes in the expected timing of cash outflows. Based on the estimated costs in the ROD, and changes in the estimated timing of cash flows, we recorded an environmental remediation charge of $549 in the fourth quarter of fiscal year 2011. Such charges could be significantly higher if costs exceed estimates. We inflate these estimated costs in current dollars until the expected time of payment and discount the cost to present value using a risk free interest rate (2.70%). At January 31, 2013 and April 30, 2012, we have recorded liabilities of $5,313 and $5,210, respectively, including the recognition of $34, $34, $103, and $103 of accretion expense in the three and nine months ended January 31, 2013 and 2012, respectively.

In September 2011, the DEC settled its environmental claim against the estate of the former GM (known as the “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. We expect the warrants to be issued in fiscal year 2013. We have not assumed that the payment of these claims will reduce our exposure.

ACCRUED CAPPING, CLOSURE AND POST CLOSURE

4. ACCRUED CAPPING, CLOSURE AND POST CLOSURE

Accrued capping, closure and post-closure costs include the current and non-current portion of costs associated with obligations for closure and post-closure of our landfills. We estimate our future capping, closure and post-closure costs in order to determine the 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 capping, closure and post-closure liabilities for the nine months ended January 31, 2013 and 2012 are as follows:

LONG-TERM DEBT AND CAPITAL LEASES

5. LONG-TERM DEBT AND CAPITAL LEASES

Amendment and Refinancing Transactions

On September 20, 2012, we entered into a second amendment to and consent under our senior secured first lien credit facility (the “Senior Credit Facility”). The amendment provided that we could use up to $50,000 of the senior secured revolving credit facility (the “2011 Revolver”) proceeds under the Senior Credit Facility to redeem our $180,000 in aggregate principal amount 11% senior second lien notes due 2014 (the “Second Lien Notes”) and to pay for any interest, fees, premium or other amounts in connection with the refinancing of the Second Lien Notes, subject to the terms and conditions to such use, as described in the amendment. The amendment also contains additional modifications, including increasing the allowed amount of senior subordinated debt from $350,000 to $450,000, adjusting the definition of bank-defined cash flow by allowing for certain add backs, adjusting the definition of consolidated total interest expense by allowing for an exclusion of non-cash interest expense associated with interest rate derivatives, and providing for adjustments to the financial covenants in the event that we tendered the Second Lien Notes.

On September 24, 2012, we initiated a cash tender offer and consent solicitation for our Second Lien Notes (the “Tender Offer”). On October 9, 2012, we repurchased $107,318 in aggregate principal amount of our then outstanding Second Lien Notes through the Tender Offer, leaving $72,682 in aggregate principal amount of Second Lien Notes outstanding. Holders who tendered the Second Lien Notes prior to the early tender date received $1,060 for each $1,000 in principal amount of Second Lien Notes repurchased, which included an early tender premium of $30 per $1,000 in principal amount of Second Lien Notes, plus accrued and unpaid interest to, but not including the early tender offer settlement date. On November 8, 2012, we redeemed the remaining $72,682 in aggregate principal amount the outstanding Second Lien Notes. The remaining holders who tendered the Second Lien Notes received $1,055 for each $1,000 in principal amount of Second Lien Notes redeemed, plus accrued and unpaid interest to, but not including the redemption date.

On October 9, 2012, we completed the offering of an additional $125,000 of 7.75% senior subordinated notes (the “2019 Notes”), which will mature on February 15, 2019. The 2019 Notes were issued at a discount of $1,863, which will be amortized to interest expense over the life of the 2019 Notes, with interest payable semiannually in arrears on February 15 and August 15 of each year, commencing February 15, 2013. The net proceeds from the offering of additional 2019 Notes, along with $50,000 of 2011 Revolver borrowings, $42,184 of net equity proceeds from the offering and sale of Class A common stock discussed in Note 7 and other available funds were used to redeem our Second Lien Notes in full and to pay related transaction costs.

The Senior Credit Facility, as amended, is subject to customary affirmative, negative and financial covenants. As of January 31, 2013, these covenants restrict fiscal year capital expenditures to 1.5 times our consolidated depreciation expenses, depletion expenses and landfill amortization expenses, set a minimum interest coverage ratio of 2.00, a maximum consolidated total funded debt to consolidated EBITDA ratio of 5.75 and a maximum senior funded debt to consolidated EBITDA ratio of 2.75. In addition to the financial covenants described above, the Senior Credit Facility, as amended, also contains a number of important 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 January 31, 2013, we were in compliance with all covenants under the indenture governing our Senior Credit Facility 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 to.

Loss on Debt Extinguishment

In the three months ended January 31, 2013, we recorded a charge of $5,914 as a loss on debt extinguishment related to the refinancing of our remaining Second Lien Notes. The loss on debt extinguishment consisted of a $1,100 non-cash write off of deferred financing costs, a $816 non-cash write off of the unamortized original issue discount and a $3,998 charge associated with the early tender premium and other fees associated with the redemption of the remaining Second Lien Notes.

In the nine months ended January 31, 2013, we recorded a charge of $15,584 as a loss on debt extinguishment related to the full refinancing of our Second Lien Notes. The loss on debt extinguishment consisted of a $2,667 non-cash write off of deferred financing costs, a $2,074 non-cash write off of the unamortized original issue discount and a $10,743 charge associated with the early tender premium and tender fees associated with the redemption of the Second Lien Notes.

STOCKHOLDERS' EQUITY

STOCKHOLDERS' EQUITY

7. STOCKHOLDERS’ EQUITY

(a) Stock Issuance

On October 3, 2012, in a registered public offering we sold 11,500 shares of Class A common stock at an average price of $4.00 per share. The net proceeds received from the registered public offering, after deducting underwriting discounts, commissions and offering expenses, were $42,184 and were used to refinance our Second Lien Notes.

(b) Stock Incentive Plans

In May 2012, we granted restricted stock units and performance stock units under the 2006 Stock Incentive Plan (the “2006 Plan”) to certain employees. The vesting of the performance stock units is based on our attainment of a targeted annual return on net assets in fiscal year 2015 and the vesting of the restricted stock units is based on continued employment over a three year period beginning on the grant date. As of January 31, 2013, the performance stock units included in the May 2012 grant could result in the issuance of up to 529 shares of Class A common stock based on the attainment of a targeted maximum annual return on net assets in fiscal year 2015 and the restricted stock units could result in the issuance of an aggregate of up to 264 shares of Class A common stock based on continued employment over the remainder of the three year service period. The performance stock units and the restricted stock units were granted at a grant date fair value of $5.17 per share.

As of January 31, 2013, we had 1,320 Class A common stock equivalents available for future grant under the 2006 Plan, inclusive of additional Class A common stock equivalents which were previously issued under our terminated plans but which have become available for grant because such awards expired or otherwise resulted in shares not being issued.

Stock options granted generally vest over a one to four year period from the date of grant and are granted at prices equal to the prevailing fair market value at the issue date. In general, stock options are issued with a life not to exceed ten years. Shares issued by us upon exercise of stock options are issued from the pool of authorized shares of Class A common stock.

A summary of stock option activity for the nine months ended January 31, 2013 is as follows:

	Stock Options			Weighted Average Exercise Price
Outstanding, April 30, 2012		1,661		$	10.55
Granted		285		$	4.03
Exercised		—		$	—
Forfeited		(589	)	$	11.43
Outstanding, January 31, 2013		1,357		$	8.81
Exercisable, January 31, 2013		981		$	10.64

A summary of restricted stock, restricted stock unit and performance stock unit activity for the nine months ended January 31, 2013 is as follows:

	Restricted Stock / Restricted Stock Units			Weighted Average Grant Price		Performance Stock Units (1)			Weighted Average Grant Price
Outstanding, April 30, 2012		784		$	4.47		596		$	4.96
Granted		415		$	5.02		316		$	5.17

Outstanding, January 31, 2013		641		$	5.09		746		$	5.04

(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 435 shares of Class A common stock.

We recorded $232, ($91), $1,486 and $1,222 of stock-based compensation expense (income) related to stock options, performance stock units, restricted stock units and restricted stock, respectively, during the three and nine months ended January 31, 2013 and 2012. We also recorded $22, $33, $75 and $85 of stock-based compensation expense related to our Employee Stock Purchase Plan during the three and nine months ended January 31, 2013 and 2012, respectively.

Stock-based compensation expense is included in general and administration expenses in the unaudited consolidated statements of operations. The unrecognized stock-based compensation expense at January 31, 2013 related to unvested stock options, restricted stock and restricted stock units was $3,017, to be recognized over a weighted average period of 1.70 years. Maximum unrecognized stock-based compensation expense at January 31, 2013 related to outstanding performance stock units, and subject to the attainment of targeted maximum annual returns on net assets, was $5,219, to be recognized over a weighted average period of 1.39 years. The unrecognized stock-based compensation expense that we expect to recognize as of January 31, 2013 related to outstanding performance stock units based on our expected attainment levels was $0.

Our calculations of stock-based compensation expense associated with stock options and our Employee Stock Purchase Plan for the three and nine months ended January 31, 2013 and 2012 were made using the Black-Scholes valuation model. The fair value of stock options grants and shares to be purchased under our Employee Stock Purchase Plan were estimated assuming no expected dividend yield using the following weighted average assumptions for the three and nine months ended January 31, 2013 and 2012:

	Three Months Ended January 31,						Nine Months Ended January 31,
	2013			2012			2013			2012
Stock Options:
Expected life		6.79 years			—			6.79 years			—
Risk-free interest rate		1.04	%		0.00	%		1.04	%		0.00	%
Expected volatility		84.55	%		0.00	%		84.55	%		0.00	%
	Three Months Ended January 31,						Nine Months Ended January 31,
	2013			2012			2013			2012
Employee Stock Purchase Plan:
Expected life		0.5 years			0.5 years			0.5 years			0.5 years
Risk-free interest rate		0.12	%		0.06	%		0.11	%		0.12	%
Expected volatility		53.09	%		53.78	%		43.73	%		47.54	%

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 unaudited consolidated statements of operations.

(c) Noncontrolling Interest

Casella-Altela Regional Environmental Services, LLC (“CARES”) is a joint venture that develops, owns and operates water and leachate treatment projects for the natural gas drilling industry in Pennsylvania and New York. Our joint venture partner in CARES is Altela, Inc. On December 13, 2012, we entered into an agreement with Altela, Inc., which increased our membership interest in CARES from 51% to 66.1% subject to a one-year claw back provision. We recorded an adjustment to reduce the noncontrolling interest by $258 to reflect the change in ownership interest in CARES. We consolidate the assets, liabilities, noncontrolling interest, and results of operations of CARES into our unaudited consolidated financial statements due to our controlling financial interest in the joint venture.

SEVERANCE AND REORGANIZATION

12. SEVERANCE AND REORGANIZATION

On August 8, 2012, we realigned our operations in order to streamline functions and improve our cost structure. Through the reorganization we have targeted improvements in certain aspects of the sales function to better facilitate customer service and retention, pricing growth, and support of strategic growth initiatives; better aligned transportation, route management and maintenance functions at the local level; and reduced corporate overhead and staff to match organizational needs and reduce costs. We recorded a one-time severance and reorganization charge of $1,793 in the second quarter of fiscal year 2013 with respect to the realignment.

In the three months ended January 31, 2013, we recorded a $1,636 severance charge related primarily to the closing of Maine Energy Recovery Company LP (“Maine Energy”), see Note 13 for further discussion, and a reorganization of senior management. The liability associated with severance and reorganization as of January 31, 2013, which is recorded in other accrued liabilities, is $1,111.

BASIS OF PRESENTATION

1. BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements include the accounts of Casella Waste Systems, Inc. (the “Parent”), its wholly-owned subsidiaries and an entity in which it has a controlling financial interest (collectively, “we”, “us” or “our”). For the consolidated subsidiary that is less than wholly-owned, the third-party holding of equity interest is referred to as a noncontrolling interest. The portion of net loss attributable to the noncontrolling interest holder of this subsidiary is presented as net loss attributable to noncontrolling interest in the unaudited consolidated statements of operations and the portion of comprehensive loss attributable to the noncontrolling interest holder of this subsidiary is presented as comprehensive loss attributable to noncontrolling interest in the unaudited consolidated statements of comprehensive loss. The portion of stockholders’ equity of this subsidiary attributable to the noncontrolling interest holder is presented as noncontrolling interest in the unaudited consolidated balance sheets and the unaudited consolidated statement of stockholders’ equity.

We are a regional, vertically-integrated solid waste services company that provides collection, transfer, disposal, landfill, landfill gas-to-energy, recycling and organics services in the northeastern United States. We market recyclable metals, aluminum, plastics, paper and corrugated cardboard, which have been processed at our recycling facilities, as well as recyclables purchased from third parties. We manage our solid waste operations on a geographic basis through two regional operating segments, the Eastern and Western regions, each of which includes a full range of solid waste services, and our larger-scale recycling and commodity brokerage operations through our Recycling segment. Ancillary operations, major customer accounts, discontinued operations and earnings through equity method investees are included in our Other segment.

The consolidated financial statements as of January 31, 2013 and for the three and nine months ended January 31, 2013 and 2012 are unaudited. These unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) and in the opinion of management, 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 nine months ended January 31, 2013 may not be indicative of the results that may be expected for any other interim period or the fiscal year ending April 30, 2013. The unaudited 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, 2012, which was filed with the SEC on June 28, 2012.

The preparation of our unaudited consolidated 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 at the date of the unaudited consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. 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, 2012.

Certain reclassifications have been made to previously reported amounts. These reclassifications had no effect on the previously reported consolidated financial position, results of operations or retained earnings.

We consider events or transactions that have occurred after the unaudited consolidated balance sheet date of January 31, 2013, but prior to the filing of the unaudited consolidated financial statements with the SEC on this Form 10-Q. We have evaluated subsequent events through the date of the filing of this Quarterly Report on Form 10-Q with the SEC.

Adoption of New Accounting Pronouncements

Comprehensive Income

In June 2011, the Financial Accounting Standards Board (the “FASB”) issued an accounting standards update for the presentation of comprehensive income. This guidance requires the presentation of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The updated standard also requires presentation of adjustments for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented. The FASB deferred certain portions of the accounting standard update related to presentation of reclassification adjustments from other comprehensive income to net income. This guidance, except for the deferred portion noted above, is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 with early adoption permitted. We adopted this guidance effective May 1, 2012. It only impacts the presentation of our financial statements and does not impact our consolidated financial position or results of operations.

New Accounting Pronouncements Pending Adoption

Comprehensive Income

In February 2013, the FASB issued an accounting standards update for the reporting of reclassifications out of accumulated other comprehensive income. This guidance requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under generally accepted accounting principles in the United States (“GAAP”) to be reclassified in its entirety to net income. For other amounts not required under GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under GAAP that provide additional detail about those amounts. This guidance is effective prospectively for annual and interim reporting periods beginning after December 15, 2012 and it will only impact the presentation of our financial statements or require additional disclosure and will not impact our consolidated financial position or results of operations.

Indefinite-Lived Intangible Assets Impairment Test

In July 2012, the FASB issued an accounting standards update on indefinite-lived intangible assets impairment testing. This guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the quantitative impairment test. If after assessing the totality of events or circumstances, we determine that it is not more likely than not that an indefinite-lived intangible asset is impaired, then we will not need to perform the quantitative impairment test in accordance with Accounting Standards Codification (“ASC”) 350-30. This guidance is effective for annual and interim indefinite-lived assets impairment tests performed for fiscal years beginning after September 15, 2012 with early adoption permitted, and we expect that it will have no impact on our consolidated financial position or results of operations.

Disclosures About Offsetting Assets and Liabilities

In December 2011, the FASB issued an accounting standards update regarding the disclosure of offsetting assets and liabilities in financial statements. This guidance requires an entity to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The objective of this disclosure is to facilitate comparison between those entities that prepare their financial statements on the basis of GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards. In January 2013, the FASB issued an accounting standards update to address implementation issues about the December 2011 accounting standards update by clarifying the scope of the offsetting disclosures. This guidance is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods, and it will only impact the presentation of our financial statements or require additional disclosure and will not impact our consolidated financial position or results of operations.
