NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(in thousands, except for per share data)


1.	BASIS OF PRESENTATION

Casella Waste Systems, Inc. (“Parent”), and its consolidated subsidiaries (collectively, “we”, “us” or “our”), is a regional, vertically integrated solid waste services company that provides collection, transfer, disposal, landfill, landfill gas-to-energy, recycling, and organics services in the northeastern United States. We market recyclable metals, aluminum, plastics, paper, and corrugated cardboard, which have been processed at our recycling facilities, as well as recyclables purchased from third-parties. We manage our solid waste operations on a geographic basis through two regional operating segments, the Eastern and Western regions, each of which provides a full range of solid waste services, and our larger-scale recycling and commodity brokerage operations through our Recycling segment. Organics services, ancillary operations, major account and industrial services, discontinued operations and earnings from equity method investees, as applicable, are included in our Other segment.

The accompanying unaudited consolidated financial statements, which include the accounts of the Parent, our wholly-owned subsidiaries and any partially owned entities over which we have a controlling financial interest, have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). All significant intercompany accounts and transactions are eliminated in consolidation. Investments in entities in which we do not have a controlling financial interest are accounted for under either the equity method or the cost method of accounting, as appropriate. Our significant accounting policies are more fully discussed in Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, which was filed with the SEC on March 2, 2017.

Preparation of our consolidated financial statements in accordance with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the accounting for and recognition and disclosure of assets, liabilities, equity, revenues and expenses. We must make these estimates and assumptions because certain information that we use is dependent on future events, cannot be calculated with a high degree of precision given the available data, or simply cannot be readily calculated. In the opinion of management, these consolidated financial statements include all adjustments, which include normal recurring and nonrecurring adjustments, necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented. The results for the three and nine months ended September 30, 2017 may not be indicative of the results for any other interim period or the entire fiscal year. The consolidated financial statements presented herein should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

Subsequent Events

We have evaluated subsequent events or transactions that have occurred after the consolidated balance sheet date of September 30, 2017 through the date of filing of the consolidated financial statements with the SEC on this Quarterly Report on Form 10-Q. We have determined that there are no subsequent events that require disclosure in this Quarterly Report on Form 10-Q.


2.	ACCOUNTING CHANGES

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



Standard	Description	Effect on the Financial Statements or Other Significant Matters
Accounting standards that are pending adoption
ASU 2017-12: Derivatives and Hedging (Topic 815)	Requires that an entity align its risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The amendments expand and refine hedge accounting for both financial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements.	The adoption of this guidance affects the designation and measurement guidance for qualifying hedging relationships and the method of presenting hedge results, including the addition of a tabular disclosure related to the effect on the income statement of fair value and cash flow hedges and no longer measuring and reporting hedge ineffectiveness. This guidance is effective January 1, 2019 with early adoption permitted.

ASU 2017-09: Compensation - Stock Compensation (Topic 718)	Requires that an entity should account for the effects of a modification to an award unless all of the following conditions are met: the fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified; the vesting conditions of the modified award are the same as the vesting conditions immediately before the original award is modified; and the classification of modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified.	The adoption of this guidance could affect equity compensation expense and net income if there is a modification of an award. This guidance is effective January 1, 2018 with early adoption permitted.

ASU 2017-04: Intangibles - Goodwill and Other (Topic 350)	Requires that when an entity is performing its annual, or interim, goodwill impairment test, it should compare the fair value of the reporting unit with its carrying amount when calculating its impairment charge, noting that the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, if applicable, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when calculating its impairment charge.	As of December 31, 2016, we did not record a goodwill impairment charge related to our annual goodwill impairment test because at that time the fair value of each reporting unit exceeded its respective carrying value. Upon adoption, if the carrying value of any of these reporting units exceeds the fair value when we perform a goodwill impairment test, we would record an impairment charge equal to the amount by which the carrying value exceeds its fair value. This guidance is effective January 1, 2020 with early adoption permitted for interim or annual goodwill impairment tests performed after January 1, 2017.

ASU 2016-02, as amended through September 2017: Leases (Topic 842)	Requires that a lessee recognize at the commencement date: a lease liability, which is the obligation of the lessee to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term.	We are currently assessing the provisions of this guidance and evaluating the timing and impact the guidance will have on our consolidated financial statements and related disclosures. We are also in the process of aggregating lease documentation for review. The adoption of this ASU primarily impacts the balance sheet through the recognition of a right-of-use asset and a lease liability for all leases with terms in excess of 12 months. This guidance is effective January 1, 2019 using a modified retrospective transition approach with early adoption permitted.

ASU 2016-01: Financial Instruments - Overall (Topic 825-10)	Requires the following: (1) equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (2) entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (3) separate presentation of financial assets and financial liabilities by measurement category and form of financial asset; and (4) the elimination of the disclosure requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost.	The adoption of this guidance results in a cumulative-effect adjustment to the balance sheet, the recognition of changes in fair value of certain equity investments in net income, and enhanced disclosure. This guidance is effective January 1, 2018 with a cumulative-effect adjustment.

ASU 2014-09, as amended through September 2017: Revenue from Contracts with Customers (Topic 606)	The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.	The adoption of this guidance requires using either a full retrospective approach for all periods presented or a modified retrospective approach. We plan to adopt the guidance using the modified retrospective approach, recognizing a cumulative effect adjustment to retained earnings as of the date of adoption. We will record revenue when control is transferred to our customer, generally at the time we provide services. We are evaluating the effect of adopting this guidance on our collection line-of-business, as well as our transfer station, landfill, transportation, energy, customer solutions, recycling and organic services lines-of- business, and we expect our operating results to remain materially unchanged. We are also assessing the effect of adopting this guidance on our disclosures and the recognition of costs we incur to obtain and fulfill our contacts. Currently, these costs are typically expensed as incurred. This guidance is effective January 1, 2018 using a full or modified retrospective approach with early adoption permitted January 1, 2017.


3.	BUSINESS COMBINATIONS

We acquired one solid waste collection business in our Eastern region and two solid waste collection businesses in our Western region during the nine months ended September 30, 2017. We acquired three transfer stations in our Western region during the nine months ended September 30, 2016. The operating results of each acquired business is included in the accompanying unaudited consolidated statements of operations from the date of acquisition, and the purchase price has been allocated to the net assets acquired based on fair values at the date of acquisition, with the residual amount recorded as goodwill.

5.	ACCRUED FINAL CAPPING, CLOSURE AND POST CLOSURE

Accrued final capping, closure and post-closure costs include the current and non-current portion of costs associated with obligations for final capping, closure and post-closure of our landfills. We estimate our future final capping, closure and post-closure costs in order to determine the final capping, closure and post-closure expense per ton of waste placed into each landfill. The anticipated time frame for paying these costs varies based on the remaining useful life of each landfill as well as the duration of the post-closure monitoring period.

A summary of the changes to accrued final capping, closure and post-closure liabilities follows:



	Nine Months Ended September 30,
	2017			2016
Beginning balance	$	44,207		$	41,041

Financing Activities

Term Loan B Facility

In the quarter ended June 30, 2017, we entered into the first amendment (“Repricing Amendment”) to our $350,000 aggregate principal amount term loan B facility ("Term Loan B Facility") and $160,000 revolving line of credit facility (“Revolving Credit Facility” and, together with the Term Loan B Facility, the "Credit Facility"). The Repricing Amendment decreased the applicable interest margin for our Term Loan B Facility by 25 basis points for both LIBOR borrowings and base rate borrowings. The applicable interest rate margin will continue to be determined based on our consolidated net leverage ratio, with the interest set at 2.75% for LIBOR borrowings (with a 1.00% LIBOR floor) and 1.75% for base rate borrowings at September 30, 2017. The applicable interest rate will be reduced to 2.50% for LIBOR borrowings (with a 1.00% LIBOR floor), and 1.50% for base rate borrowings upon us reaching a consolidated net leverage ratio of 3.75x or less.

Maine Bonds

In the quarter ended March 31, 2017, we completed the remarketing of $3,600 aggregate principal amount of Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-1 (“FAME Bonds 2005R-1”) and $21,400 aggregate principal amount of Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-2 (“FAME Bonds 2005R-2”) into one series of $25,000 aggregate principal amount Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-3 (“FAME Bonds 2005R-3”). The FAME Bonds 2005R-3, which are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 5.25% per annum until they mature on January 1, 2025.

Loss on Debt Extinguishment

We recorded a loss on debt extinguishment of $0 and $517 in the three and nine months ended September 30, 2017, respectively, as compared to a loss on debt extinguishment of $191 and $736 during the three and nine months ended September 30, 2016, respectively, associated with the following:


•	the write-off of debt issuance costs in connection with the Repricing Amendment in the quarter ended June 30, 2017;


•	the write-off of debt issuance costs in connection with the remarketing of the FAME Bonds 2005R-1 and the FAME Bonds 2005R-2 into the FAME Bonds 2005R-3 in the quarter ended March 31, 2017; and


•	the repurchase price premium and write-off of debt issuance costs and unamortized original issue discount associated with the early redemption, repurchase and retirement of partial portions of our 7.75% senior subordinated notes due February 2019 in the three and nine months ended September 30, 2016.

Cash Flow Hedges

In the quarter ended March 31, 2017, we entered into three interest rate derivative agreements to hedge interest rate risk associated with the variable rate portion of our long-term debt. The total notional amount of these agreements is $60,000 and requires us to receive interest based on changes in the 1-month LIBOR index with a 1.0% floor and pay interest at a weighted average rate of approximately 1.95%. Two of the agreements, with a total notional amount of $35,000, mature in February 2021, and the final agreement, with a total notional amount of $25,000, matures in February 2022. We have designated these derivative instruments as cash flow hedges.

In accordance with the derivatives and hedging guidance in FASB ASC 815 - Derivatives and Hedging, the effective portions of the changes in fair values of interest rate swaps have been recorded in equity as a component of accumulated other comprehensive loss, net of tax. As the critical terms of the interest rate swaps match the underlying debt being hedged, no ineffectiveness is recognized on these swaps and, therefore, all unrealized changes in fair value are recorded in accumulated other comprehensive loss, net of tax. Amounts are reclassified from accumulated other comprehensive loss, net of tax into earnings in the same period or periods during which the hedged transaction affects earnings.

As of September 30, 2017, we have recorded a derivative asset with a fair value of $58 in other non-current assets and a derivative liability with a fair value of $321 in other accrued liabilities associated with these cash flow hedges.

7. COMMITMENTS AND CONTINGENCIES

Legal Proceedings

In the ordinary course of our business and as a result of the extensive governmental regulation of the solid waste industry, we are subject to various judicial and administrative proceedings involving state and local agencies. In these proceedings, an agency may seek to impose fines or to revoke or deny renewal of an operating permit held by us. From time to time, we may also be subject to actions brought by special interest or other groups, adjacent landowners or residents in connection with the permitting and licensing of landfills and transfer stations, or allegations of environmental damage or violations of the permits and licenses pursuant to which we operate. In addition, we may be named defendants in various claims and suits pending for alleged damages to persons and property, alleged violations of certain laws and alleged liabilities arising out of matters occurring during the ordinary operation of a waste management business.

In accordance with FASB ASC 450 - Contingencies, we accrue for legal proceedings, inclusive of legal costs, when losses become probable and reasonably estimable. As of the end of each applicable reporting period, we review each of our legal proceedings to determine whether it is probable, reasonably possible or remote that a liability has been incurred and, if it is at least reasonably possible, whether a range of loss can be reasonably estimated under the provisions of FASB ASC 450-20. In instances where we determine that a loss is probable and we can reasonably estimate a range of loss we may incur with respect to such a matter, we record an accrual for the amount within the range that constitutes our best estimate of the possible loss. If we are able to reasonably estimate a range, but no amount within the range appears to be a better estimate than any other, we record an accrual in the amount that is the low end of such range. When a loss is reasonably possible, but not probable, we will not record an accrual, but we will disclose our estimate of the possible range of loss where such estimate can be made in accordance with FASB ASC 450-20.

Environmental Remediation Liability

We are subject to liability for environmental damage, including personal injury and property damage, that our solid waste, recycling and power generation facilities may cause to neighboring property owners, particularly as a result of the contamination of drinking water sources or soil, possibly including damage resulting from conditions that existed before we acquired the facilities. We may also be subject to liability for similar claims arising from off-site environmental contamination caused by pollutants or hazardous substances if we or our predecessors arrange or arranged to transport, treat or dispose of those materials. The following matters represent our material outstanding claims.

Southbridge Recycling & Disposal Park, Inc.

In October 2015, our Southbridge Recycling and Disposal Park, Inc. (“SRD”) subsidiary reported to the Massachusetts Department of Environmental Protection (“MADEP”) results of analysis of samples collected pursuant to our existing permit from private drinking water wells located near the Town of Southbridge, Massachusetts (“Town”) Landfill (“Southbridge Landfill”), which is operated by SRD. Those results indicated the presence of contaminants above the levels triggering notice and response obligations under MADEP regulations. In response to those results, we are carrying out an Immediate Response Action pursuant to Massachusetts General Law Chapter 21E (the "Charlton 21E Obligations") pursuant to state law. Further, we have implemented a plan to analyze and better understand the groundwater near the Southbridge Landfill and we are investigating with the objective of identifying the source or sources of the elevated levels of contamination measured in the well samples. If it is determined that some or all of the contamination originated at the Southbridge Landfill, we will work with the Town (the Southbridge Landfill owner and the former operator of an unlined portion of the Southbridge Landfill, which was used prior to our operation of a double-lined portion of the Southbridge Landfill commencing in 2004) to evaluate and allocate the liabilities related to the Charlton 21E Obligations. In July 2016, we sent correspondence to the Town pursuant to Chapter 21E of Massachusetts General Laws demanding that the Town reimburse us for the environmental response costs we had spent and that the Town be responsible for all such costs in the future, as well as any other costs or liabilities resulting from the release of contaminants from the unlined portion of the Southbridge Landfill. The Town responded in September 2016, denying that the Southbridge Landfill is the source of such contamination, and claiming that if it is, that we may owe an indemnity to the Town pursuant to the Operating Agreement between us and the Town dated May 29, 2007, as amended. We entered into a Tolling Agreement with the Town to delay any further administrative or legal actions until our work with MADEP more specifically defines the parties’ responsibilities for the Charlton 21E Obligations, if any. Please see below for further discussion of our relationship with the Town regarding the Charlton 21E Obligations.

In February 2016, we and the Town received a Notice of Intent to Sue under the Resource Conservation and Recovery Act ("RCRA") from a law firm purporting to represent residents proximate to the Southbridge Landfill (“Residents”), indicating its intent to file suit against us on behalf of the Residents alleging the groundwater contamination originated from the Southbridge Landfill. In February 2017, we received an additional Notice of Intent to Sue from the National Environmental Law Center under the Federal Clean Water Act ("CWA") and RCRA (collectively the “Acts”) on behalf of Environment America, Inc., d/b/a Environment Massachusetts, and Toxics Action Center, Inc., which have referred to themselves as the Citizen Groups. The Citizen Groups alleged that we had violated the Acts, and that they intended to seek appropriate relief in federal court for those alleged violations. On or about June 9, 2017, a lawsuit was filed against us, SRD and the Town in the United States District Court for the District of Massachusetts by the Citizen Groups and the Residents alleging violations of the Acts (the “Litigation”), and demanding a variety of remedies under the Acts, including fines, remediation, mitigation and costs of litigation, and remedies for violations of Massachusetts civil law related to personal and property damages, including remediation, diminution of property values, compensation for lost use and enjoyment of properties, enjoinment of further operation of the Southbridge Landfill, and costs of litigation, plus interest on any damage award, on behalf of the Residents. We believe the Litigation to be factually inaccurate, and without legal merit, and we and SRD intend to vigorously defend the Litigation. Nevertheless, we believe it is reasonably possible that a loss will occur as a result of the Litigation although an estimate of loss cannot be reasonably provided at this time due to the infancy of this matter. We also continue to believe the Town should be responsible for costs or liabilities associated with the Litigation relative to alleged contamination originating from the unlined portion of the Southbridge Landfill, although there can be no assurance that we will not be required to incur some or all of such costs and liabilities.

We entered into an Administrative Consent Order on April 26, 2017 (the “ACO”), with MADEP, the Town, and the Town of Charlton, committing us to equally share the costs with MADEP, of up to $10,000 ($5,000 each) for the Town to install a municipal waterline in the Town of Charlton ("Waterline"). Upon satisfactory completion of that Waterline, and other matters covered by the ACO, we and the Town will be released by MADEP from any future responsibilities for the Charlton 21E Obligations. We also entered into an agreement with the Town on April 28, 2017 entitled the “21E Settlement and Water System Construction Funding Agreement” (the “Waterline Agreement”), wherein we and the Town released each other from claims arising from the Charlton 21E Obligations. Pursuant to the Waterline Agreement, the Town will issue a twenty (20) year bond for our portion of the Waterline costs (up to $5,000). We have agreed to reimburse the Town for periodic payments under such bond.

We have recorded an environmental remediation liability associated with the future installation of the Waterline in other accrued liabilities and other long-term liabilities. We inflate the estimated costs in current dollars to the expected time of payment and discount the total cost to present value using a risk-free interest rate of 2.6%. Our expenditures could be significantly higher if costs exceed estimates. The changes to the environmental remediation liability associated with the Southbridge Landfill are as follows:

In August 2016, we filed a complaint against Steadfast Insurance Company (“Steadfast”) in the Superior Court of Suffolk County, Massachusetts (the "Court"), alleging among other things, that Steadfast breached its Pollution Liability Policy (“Policy”) purchased by us in April 2015, by refusing to acknowledge coverage under the Policy, and refusing to cover any of the costs and liabilities incurred by us as described above as well as costs and liabilities that we may incur in the future. Steadfast filed an answer and counterclaim in September 2016, denying that it has any obligations to us under the Policy, and seeking a declaratory judgment of Steadfast’s obligations under the Policy. We are in the discovery phase of this litigation. Steadfast has filed a Motion to Dismiss (the "Motion") our litigation against it, and we filed our response on July 11, 2017. On September 7, 2017, the Court denied the Motion.

On June 13, 2017, Town voters rejected a non-binding ballot initiative intended to provide guidance to Town officials with respect to our pursuit of other landfill development opportunities at the Southbridge Landfill. Following such rejection by the Town voters, our board of directors and senior management determined after due consideration of all facts and circumstances that it is no longer likely that further development at the existing landfill site will generate an adequate risk adjusted return at the Southbridge Landfill, and accordingly we expect to cease operations at the Southbridge Landfill when no further capacity is available, expected by no later than December 31, 2018. We delivered correspondence to the Town to this effect on August 3, 2017, citing events of Change in Law and Force Majeure pursuant to our May 29, 2007 Extension Agreement with the Town ("Extension Agreement") and the impacts of such events on further expansion of the Southbridge Landfill. We have advised the Town that we see no economically feasible way to operate the Southbridge Landfill beyond its current permitted life. Following cessation of operations, we will proceed to conduct proper closure and other activities at the Southbridge Landfill in accordance with the Extension Agreement with the Town, and Federal, state and local law. We reached this conclusion after carefully evaluating the estimated future costs associated with the permitting, engineering and construction activities for the planned expansion of the Southbridge Landfill against the possible outcomes of the permitting process and the anticipated future benefits of successful expansions. Under the Extension Agreement, which we account for as an operating lease, there are potential contractual obligations and commitments, including future cash payments of $3,069 and services that extend beyond the current useful life of the Southbridge Landfill. In accordance with FASB ASC 420 - Exit or Disposal Cost Obligations, a liability for costs to be incurred under a contract for its remaining term without economic benefit shall be recognized when we cease using the right conveyed by the contract. We may incur a loss associated with these potential contractual obligations upon cessation of operations at the Southbridge Landfill when remaining capacity is exhausted by the placement of waste at the site. See Note10, Other Items and Charges to our consolidated financial statements included under Part I, Item 1 of this Quarterly Report on Form 10-Q for information regarding the Southbridge Landfill closure charge.

The costs and liabilities we may be required to incur in connection with the foregoing Southbridge Landfill matters could be material to our results of operations, our cash flows and our financial condition.

Potsdam Environmental Remediation Liability

On December 20, 2000, the State of New York Department of Environmental Conservation (“DEC”) issued an Order on Consent (“Order”) which named Waste-Stream, Inc. (“WSI”), our subsidiary, General Motors Corporation (“GM”) and Niagara Mohawk Power Corporation (“NiMo”) as Respondents. The Order required that the Respondents undertake certain work on a 25-acre scrap yard and solid waste transfer station owned by WSI in Potsdam, New York, including the preparation of a Remedial Investigation and Feasibility Study (“Study”). A draft of the Study was submitted to the DEC in January 2009 (followed by a final report in May 2009). The Study estimated that the undiscounted costs associated with implementing the preferred remedies would be approximately $10,219. On February 28, 2011, the DEC issued a Proposed Remedial Action Plan for the site and accepted public comments on the proposed remedy through March 29, 2011. We submitted comments to the DEC on this matter. In April 2011, the DEC issued the final Record of Decision (“ROD”) for the site. The ROD was subsequently rescinded by the DEC for failure to respond to all submitted comments. The preliminary ROD, however, estimated that the present cost associated with implementing the preferred remedies would be approximately $12,130. The DEC issued the final ROD in June 2011 with proposed remedies consistent with its earlier ROD. An Order on Consent and Administrative Settlement naming WSI and NiMo as Respondents was executed by the Respondents and DEC with an effective date of October 25, 2013. On January 29, 2016, a Cost-Sharing Agreement was executed between WSI, NiMo, Alcoa Inc. (“Alcoa”) and Reynolds Metal Company (“Reynolds”) whereby Alcoa and Reynolds elected to voluntarily participate in the onsite remediation activities at a combined 15% participant share. It is unlikely that any significant expenditures relating to onsite remediation will be incurred until the fiscal year ending December 31, 2019. WSI is jointly and severally liable with NiMo, Alcoa and Reynolds for the total cost to remediate.

We have recorded an environmental remediation liability associated with the Potsdam site based on incurred costs to date and estimated costs to complete the remediation in other accrued liabilities and other long-term liabilities. Our expenditures could be significantly higher if costs exceed estimates. We inflate the estimated costs in current dollars to the expected time of payment and discount the total cost to present value using a risk-free interest rate of 1.5%. The changes to the environmental remediation liability associated with the Potsdam site are as follows:




	Nine Months Ended September 30,

8.	STOCKHOLDERS' EQUITY

Stock Based Compensation

Shares Available For Issuance

In the fiscal year ended December 31, 2016, we adopted the 2016 Incentive Plan (“2016 Plan”). Under the 2016 Plan, we may grant awards up to an aggregate amount of shares equal to the sum of: (i) 2,250 shares of Class A common stock (subject to adjustment in the event of stock splits and other similar events), plus (ii) such additional number of shares of Class A common stock (up to 2,723 shares) as is equal to the sum of the number of shares of Class A common stock that remained available for grant under the 2006 Stock Incentive Plan (“2006 Plan”) immediately prior to the expiration of the 2006 Plan and the number of shares of Class A common stock subject to awards granted under the 2006 Plan that expire, terminate or are otherwise surrendered, canceled, forfeited or repurchased by us. As of September 30, 2017, there were 1,904 Class A common stock equivalents available for future grant under the 2016 Plan.

Stock Options

Stock options are granted at a price equal to the prevailing fair value of our Class A common stock at the date of grant. Generally, stock options granted have a term not to exceed ten years and vest over a one year to four year period from the date of grant.

The fair value of each stock option granted, with the exception of market-based performance stock option grants, is estimated using a Black-Scholes option-pricing model, which requires extensive use of accounting judgment and financial estimation, including estimates of the expected term stock option holders will retain their vested stock options before exercising them and the estimated volatility of our Class A common stock price over the expected term. The fair value of each market-based performance stock option granted is estimated using a Monte Carlo option-pricing model, which also requires extensive use of accounting judgment and financial estimation, including estimates of the expected term stock option holders will retain their vested stock options before exercising them and the estimated volatility of our Class A common stock price over the expected term, but also including estimates of share price appreciation plus the value of dividends of our Class A common stock as compared to the Russell 2000 Index over the requisite service period.

A summary of stock option activity follows:



	Stock Options (1)		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (years)	Aggregate Intrinsic Value
Outstanding, December 31, 2016	1,115		$	6.13
Granted	—		$	—
Exercised	(91	)	$	10.97
Forfeited	(5	)	$	7.54
Outstanding, September 30, 2017	1,019		$	5.68	5.5	$	13,366
Exercisable, September 30, 2017	819		$	5.00	4.8	$	11,305
Unvested, September 30, 2017	240		$	9.16	8.5	$	2,313


(1)	Market-based performance stock options are included at the 100% attainment level. Attainment of the maximum performance targets and market achievements would result in the issuance of an additional 40 shares of Class A common stock currently included in unvested.

Stock-based compensation expense for stock options was $158 and $505 during the three and nine months ended September 30, 2017, respectively, as compared to $143 and $435 during the three and nine months ended September 30, 2016, respectively.

During the three and nine months ended September 30, 2017, the aggregate intrinsic value of stock options exercised was $91 and $297, respectively.

As of September 30, 2017, total unrecognized stock-based compensation expense related to outstanding stock options, including market-based performance stock options assuming the attainment of maximum performance targets, was $613, which will be recognized over a weighted average period of 0.9 years.

Other Stock Awards

Restricted stock awards, restricted stock units and performance stock units, with the exception of market-based performance stock units, are granted at a price equal to the fair value of our Class A common stock at the date of grant. The fair value of each market-based performance stock unit is estimated using a Monte Carlo pricing model, which requires extensive use of accounting judgment and financial estimation, including the estimated share price appreciation plus the value of dividends of our Class A common stock as compared to the Russell 2000 Index over the requisite service period.

Restricted stock awards granted to non-employee directors vest incrementally over a three year period beginning on the first anniversary of the date of grant. Restricted stock units granted to non-employee directors vest in full on the first anniversary of the grant date. Restricted stock units granted to employees vest incrementally over an identified service period beginning on the grant date based on continued employment. Performance stock units granted to employees, including market-based performance stock units, vest at a future date following the grant date and are based on the attainment of performance targets and market achievements, as applicable.

A summary of restricted stock, restricted stock unit and performance stock unit activity follows:



	Restricted Stock, Restricted Stock Units, and Performance Stock Units (1)		Weighted Average Grant Date Fair Value		Weighted Average Remaining Contractual Term (years)	Aggregate Intrinsic Value
Outstanding, December 31, 2016	1,099		$	7.03
Granted	439		$	12.32
Class A Common Stock Vested	(376	)	$	5.08
Forfeited	(23	)	$	6.09
Outstanding, September 30, 2017	1,139		$	9.66	1.5	$	10,403
Unvested, September 30, 2017	1,501		$	10.35	1.6	$	12,679


(1)	Market-based performance stock unit grants are included at the 100% attainment level. Attainment of the maximum performance targets and market achievements would result in the issuance of an additional 362 shares of Class A common stock currently included in unvested.

Stock-based compensation expense related to restricted stock, restricted stock units and performance stock units was $1,684 and $4,183 during the three and nine months ended September 30, 2017, respectively, as compared to $585 and $1,863 during the three and nine months ended September 30, 2016, respectively.

During the three and nine months ended September 30, 2017, the total fair value of other stock awards vested was $97 and $4,867, respectively.

As of September 30, 2017, total unrecognized stock-based compensation expense related to outstanding restricted stock and restricted stock units was $3,701, which will be recognized over a weighted average period of 1.4 years. As of September 30, 2017, maximum unrecognized stock-based compensation expense related to outstanding performance stock units, assuming the attainment of maximum performance targets, was $6,039 to be recognized over a weighted average period of 1.7 years.

The weighted average fair value of market-based performance stock units granted during the nine months ended September 30, 2017 was $12.51 per award, which was calculated using a Monte Carlo pricing model assuming a risk free interest rate of 1.45% and an expected volatility of 32.80% assuming no expected dividend yield. The risk-free interest rate is based on the U.S. Treasury yield curve for the expected service period of the award. Expected volatility is calculated using the daily volatility of our Class A common stock over the expected service period of the award.

The Monte Carlo pricing model requires extensive use of accounting judgment and financial estimation. Application of alternative assumptions could produce significantly different estimates of the fair value of stock-based compensation and consequently, the related amounts recognized in the consolidated statements of operations.

We also recorded $31 and $96 of stock-based compensation expense related to our Amended and Restated 1997 Employee Stock Purchase Plan during the three and nine months ended September 30, 2017, respectively, as compared to $28 and $79 during the three and nine months ended September 30, 2016, respectively.

9.	EARNINGS PER SHARE

Basic earnings per share is computed by dividing the net income (loss) from continuing operations attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated based on the combined weighted average number of common shares and potentially dilutive shares, which include the assumed exercise of employee stock options, including market-based performance stock options based on the expected achievement of performance targets, unvested restricted stock awards, unvested restricted stock units and unvested performance stock units, including market-based performance units based on the expected achievement of performance targets. In computing diluted earnings per share, we utilize the treasury stock method.

A summary of the numerator and denominators used in the computation of earnings per share follows:

10.	Other Items and Charges

Southbridge Landfill Closure Charge

In June 2017, we initiated the plan to cease operations of the Southbridge Landfill as disclosed in Note 7, Commitments and Contingencies. Accordingly, in the three and nine months ended September 30, 2017, we recorded charges associated with the closure of the Southbridge Landfill as follows:



	Three Months Ended September 30,					Nine Months Ended September 30,
	2017		2016			2017		2016
Asset impairment charge (1)	$	—	$	—		$	47,999	$	—
Project development charge (2)	—		—			9,149		—

Legal and transaction costs (4)	754		—			1,341		—
Southbridge Landfill closure charge	$	754	$	—	—	$	64,868	$	—

(1)

We performed a test of recoverability under FASB ASC 360 - Property, Plant, and Equipment, which indicated that the carrying value of our asset group that includes the Southbridge Landfill was no longer recoverable and, as a result, the asset group was assessed for impairment with an impairment charge allocated to the long-lived assets of the Southbridge Landfill in accordance with FASB ASC 360 - Property, Plant, and Equipment.


(2)	We wrote-off deferred costs associated with Southbridge Landfill permitting activities no longer deemed viable.


(3)	We recorded an environmental remediation charge associated with the future installation of a municipal waterline. See Note 7, Commitments and Contingencies for additional disclosure.


(4)	We incurred legal and other transaction costs associated with various matters as part of the Southbridge Landfill closure. See Note 7, Commitments and Contingencies for additional disclosure.


11.	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 that we believe market participants would use in pricing an asset or a liability.

Assets and Liabilities Accounted for at Fair Value

Our financial instruments include cash and cash equivalents, accounts receivable-trade, restricted cash and investments held in trust on deposit with various banks as collateral for our obligations relative to our landfill final capping, closure and post-closure costs, interest rate derivatives, trade payables and long-term debt. The carrying values of cash and cash equivalents, accounts receivable - trade and trade payables approximate their respective fair values due to their short-term nature. The fair value of restricted cash and investments held in trust, which are valued using quoted market prices, are included as restricted assets in the Level 1 tier below. The fair value of the interest rate derivatives included in the Level 2 tier below is calculated using discounted cash flow valuation methodologies based upon the one month LIBOR yield curves that are observable at commonly quoted intervals for the full term of the swaps.

Recurring Fair Value Measurements

Summaries of our financial assets and liabilities that are measured at fair value on a recurring basis follow:



	Fair Value Measurement at September 30, 2017 Using:
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Assets:

Assets:
Restricted investments - landfill closure	$	1,002	$	—	$	—

Fair Value of Debt

As of September 30, 2017, the fair value of our fixed rate debt, including our FAME Bonds 2005R-3, Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2015 (“FAME Bonds 2015”), Vermont Economic Development Authority Solid Waste Disposal Long-Term Revenue Bonds Series 2013 (“Vermont Bonds”), New York State Environmental Facilities Corporation Solid Waste Disposal Revenue Bonds Series 2014 (“New York Bonds 2014”), New York State Environmental Facilities Corporation Solid Waste Disposal Revenue Bonds Series 2014R-2 (“New York Bonds 2016”) and Solid Waste Disposal Revenue Bonds Series 2013 issued by the Business Finance Authority of the State of New Hampshire (“New Hampshire Bonds”) was approximately $106,053 and the carrying value was $107,000. The fair value of the FAME Bonds 2005R-3, the FAME Bonds 2015, the Vermont Bonds, the New York Bonds 2014, the New York Bonds 2016 and the New Hampshire Bonds is considered to be Level 2 within the fair value hierarchy as the fair value is determined using market approach pricing provided by a third-party that utilizes pricing models and pricing systems, mathematical tools and judgment to determine the evaluated price for the security based on the market information of each of the bonds or securities with similar characteristics.

As of September 30, 2017, the fair value of our Term Loan B Facility was approximately $349,121 and the carrying value was $348,250. The fair value of the Term Loan B Facility is considered to be Level 2 within the fair value hierarchy as its fair value is based off of quoted market prices in a principal to principal market with limited public information. As of September 30, 2017, the fair value of our Revolving Credit Facility approximated its carrying value of $36,300 based on current borrowing rates for similar types of borrowing arrangements, or Level 2 inputs.

Although we have determined the estimated fair value amounts of the Term Loan B Facility, FAME Bonds 2005R-3, FAME Bonds 2015, Vermont Bonds, New York Bonds 2014, New York Bonds 2016 and New Hampshire Bonds using available market information and commonly accepted valuation methodologies, a change in available market information, and/or the use of different assumptions and/or estimation methodologies could have a material effect on the estimated fair values. These amounts have not been revalued, and current estimates of fair value could differ significantly from the amounts presented.


12.	SEGMENT REPORTING

We report selected information about operating segments in a manner consistent with that used for internal management reporting. We classify our solid waste operations on a geographic basis through regional operating segments, our Western and Eastern regions. Revenues associated with our solid waste operations are derived mainly from solid waste collection and disposal, landfill, landfill gas-to-energy, transfer and recycling services in the northeastern United States. Our revenues in the Recycling segment are derived from municipalities and customers in the form of processing fees, tipping fees and commodity sales. Organics services, ancillary operations, major account and industrial services, discontinued operations, and earnings from equity method investees, as applicable, are included in our Other segment.

Company Overview

Founded in 1975 with a single truck, Casella Waste Systems, Inc., a Delaware corporation, its wholly-owned subsidiaries and certain partially owned entities over which it has a controlling financial interest (collectively, “we”, “us” or “our”), is a regional, vertically-integrated solid waste services company. We provide resource management expertise and services to residential, commercial, municipal and industrial customers, primarily in the areas of solid waste collection and disposal, transfer, recycling and organics services. We provide integrated solid waste services in six states: Vermont, New Hampshire, New York, Massachusetts, Maine and Pennsylvania, with our headquarters located in Rutland, Vermont. We manage our solid waste operations on a geographic basis through two regional operating segments, the Eastern and Western regions, each of which provides a full range of solid waste services, and our larger-scale recycling and commodity brokerage operations through our Recycling segment. Organics services, ancillary operations, major account and industrial services, discontinued operations, and earnings from equity method investees, as applicable, are included in our Other segment.

As of October 16, 2017, we owned and/or operated 31 solid waste collection operations, 46 transfer stations, 18 recycling facilities, nine Subtitle D landfills, four landfill gas-to-energy facilities and one landfill permitted to accept construction and demolition (“C&D”) materials.

Recent Events

In the quarter ended June 30, 2017, we recorded a charge of $64.1 million associated with our decision to cease operations at the Town of Southbridge, Massachusetts ("Town") Landfill ("Southbridge Landfill"), including an asset impairment charge of $48.0 million related to our asset group that includes the Southbridge Landfill asset; a project development charge of $9.1 million related to the write-off of deferred costs associated with landfill permitting activities no longer deemed viable; an environmental remediation charge of $6.4 million associated with the future installation of a municipal waterline; and a charge of $0.6 million for legal and transaction costs associated with various matters as part of the Southbridge Landfill closure. Additionally, in the three months ended September 30, 2017, we recorded a charge of $0.8 million for legal costs associated with various matters as a part of the Southbridge Landfill closure. As part of our decision to cease operations, we assessed the estimated costs and timing of cash flows associated with remaining capital expenditures, environmental remediation, and final capping, closure and post-closure activities at the Southbridge Landfill. We expect cash outflows in the next five years associated with these activities to be approximately $21.0 million and we do not believe that this will negatively impact our liquidity during this time. In addition, we estimate that over $52.0 million in additional tax deductions relating to ceasing operations will be recognized in the next five years. Furthermore, we do not believe that ceasing operations at the Southbridge Landfill will impact our future operational activities in a manner that will have a material impact to our results of operations, our cash flows or our financial condition. For additional information, see Note 7, Commitments and Contingencies and Note 10, Other Items and Charges to our consolidated financial statements included under Part I, Item 1 of this Quarterly Report on Form 10-Q.

Results of Operations

Revenues

We manage our solid waste operations, which include a full range of solid waste services, on a geographic basis through two regional operating segments, which we designate as the Eastern and Western regions. Revenues in our Eastern and Western regions consist primarily of fees charged to customers for solid waste collection and disposal, landfill, landfill gas-to-energy, transfer and recycling services. We derive a substantial portion of our collection revenues from commercial, industrial and municipal services that are generally performed under service agreements or pursuant to contracts with municipalities. The majority of our residential collection services are performed on a subscription basis with individual households. Landfill and transfer customers are charged a tipping fee on a per ton basis for disposing of their solid waste at our disposal facilities and transfer stations. We also generate and sell electricity at certain of our landfill facilities. Revenues from our Recycling segment consist of revenues derived from municipalities and customers in the form of processing fees, tipping fees and commodity sales. Revenues from organics services, ancillary operations, and major account and industrial services are included in our Other segment. Our revenues are shown net of inter-company eliminations.

A summary of revenues attributable to service provided (dollars in millions and as a percentage of total revenues) follows:

•	$2.5 million from favorable commodity pricing in the marketplace; and


•	$0.1 million from higher commodity volumes; partially offset by


•	$(0.6) million from lower tipping fees, as we reduced variable tipping fees at our facilities as commodity prices increased.

Year-to-date recycling revenues increased as a result of the following:


•	$12.6 million from favorable commodity pricing in the marketplace; and


•	$1.6 million from higher commodity volumes; partially offset by


•	$(2.9) million from lower tipping fees, as we reduced variable tipping fees at our facilities as commodity prices increased.

Operating Expenses

A summary of cost of operations, general and administration expense, and depreciation and amortization expense (dollars in millions and as a percentage of total revenues) is as follows:



	Three Months Ended September 30,								$ Change		Nine Months Ended September 30,								$ Change
	2017				2016				$ Change		2017				2016				$ Change
Cost of operations	$	103.9	64.8	%	$	98.8	65.4	%	$	5.1	$	301.0	67.2	%	$	284.4	67.5	%	$	16.6
General and administration	$	20.8	12.9	%	$	18.8	12.4	%	$	2.0	$	58.4	13.0	%	$	55.5	13.2	%	$	2.9
Depreciation and amortization	$	16.6	10.4	%	$	16.2	10.7	%	$	0.4	$	46.3	10.3	%	$	46.4	11.0	%	$	(0.1	)

Cost of Operations

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

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

Third-party direct costs increased $2.9 million quarterly and $7.9 million year-to-date due to the following:


•	higher purchased material costs in our Recycling and Customer Solutions lines-of-business;


•	higher disposal costs associated with higher transfer station volumes and third-party disposal pricing in the Western region, and additional costs from the use of alternative disposal sites in our Organics line-of-business; and

•

higher hauling and transportation costs with higher collection volumes in the Eastern region; and higher quarterly hauling and transportation costs with increased volumes on lower margin commercial work in our Customer Solutions line-of-business; partially offset by lower hauling and transportation costs associated with decreased transportation services provided in the Western region; and lower commodity volumes in our Organics line-of-business.

Labor and related benefit costs increased $0.5 million quarterly and $3.5 million year-to-date due to the following:


•	higher healthcare costs of $1.6 million year-to-date associated with direct operational labor;


•	higher labor costs associated with higher collection volumes in the Eastern region as well as customer growth related to several new municipal contracts; and


•	higher labor costs associated with higher volumes and higher product quality standards from commodity buyers resulting in lower throughput and additional manpower in our Recycling line-of-business.

Direct operational costs increased $1.3 million quarterly and $3.4 million year-to-date due to the following:


•	higher leachate disposal costs and landfill operating costs at certain landfills in the Western region due to increased rainfall through early summer and the timing of various landfill construction projects;


•	higher host community fees associated with increased volumes at certain landfills in the Western region;


•	higher quarterly accretion expense associated with the acceleration of asset retirement obligations due to the closure of the Southbridge Landfill; and


•	higher equipment rental costs in the Eastern region; partially offset by


•	lower landfill operating costs associated with certain landfills in the Eastern region.

Maintenance and repair costs increased $0.1 million quarterly and $1.2 million year-to-date due primarily to higher fleet maintenance costs in the Western region.

General and Administration

General and administration expense includes management, clerical and administrative compensation, bad debt expense, as well as overhead costs, professional service fees and costs associated with marketing, sales force and community relations efforts.

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

Labor and related benefit costs increased $1.7 million quarterly and $2.7 million year-to-date primarily due to higher healthcare costs, which were up $0.7 million year-to-date and higher equity compensation expense of $1.1 million quarterly and $2.4 million year-to-date associated with market-based performance stock option and market-based performance stock unit grants, the majority of which were not outstanding as of September 30, 2016. These costs were partially offset by lower accrued incentive compensation of $(0.5) million year-to-date.

Bad debt expense decreased $(0.1) million quarterly and $(0.9) million year-to-date due to improved credit processes and an easier comparison due to collectability issues associated with a disposal customer in the prior year.

Other expenses increased $0.7 million quarterly and $1.1 million year-to-date due to higher recruiting and software and information technology consulting costs.

Depreciation and Amortization

Depreciation and amortization expense includes: (i) depreciation of property and equipment (including assets recorded for capital leases) on a straight-line basis over the estimated useful lives of the assets; (ii) amortization of landfill costs (including those costs incurred and all estimated future costs for landfill development and construction, along with asset retirement costs arising from closure and post-closure obligations) on a units-of-consumption method as landfill airspace is consumed over the total estimated remaining capacity of a site, which includes both permitted capacity and unpermitted expansion capacity that meets certain criteria for amortization purposes; (iii) amortization of landfill asset retirement costs arising from final capping obligations on a units-of-consumption method as airspace is consumed over the estimated capacity associated with each final capping event; and (iv) amortization of intangible assets with a definite life, using either an economic benefit provided approach or on a straight-line basis over the definitive terms of the related agreements.

A summary of the components of depreciation and amortization expense (dollars in millions and as a percentage of total revenues) follows:



	Three Months Ended September 30,								$ Change			Nine Months Ended September 30,								$ Change
	2017				2016				$ Change			2017				2016				$ Change
Depreciation	$	8.0	5.0	%	$	8.2	5.4	%	$	(0.2	)	$	24.1	5.4	%	$	24.9	5.9	%	$	(0.8	)
Landfill amortization	8.1		5.0	%	7.4		4.9	%	0.7			$	20.6	4.6	%	$	19.9	4.7	%	0.7
Other amortization	0.5		0.3	%	0.6		0.4	%	(0.1		)	$	1.6	0.4	%	$	1.6	0.4	%	—
	$	16.6	10.3	%	$	16.2	10.7	%	$	0.4		$	46.3	10.4	%	$	46.4	11.0	%	$	(0.1	)

The period-to-period changes in depreciation and amortization expense can be primarily attributed to the timing of capital expenditures and related make-up of fixed assets, the landfill amortization rate and volume mix at our landfills (higher landfill volumes in the Western region, offset by lower volumes in the Eastern region) and the makeup and timing of definite life intangible assets.

Southbridge Landfill Closure Charge

In June 2017, we initiated the plan to cease operations of the Southbridge Landfill in the Eastern region. Accordingly, we recorded charges associated with the closure of the Southbridge Landfill discussed in Note 7, Commitments and Contingencies to our consolidated financial statements included under Part I, Item 1 of this Quarterly Report on Form 10-Q as follows (dollars in millions):



	Three Months Ended September 30,					Nine Months Ended September 30,
	2017		2016			2017		2016
Asset impairment charge (1)	$	—	$	—		$	48.0	$	—
Project development charge (2)	—		—			9.1		—
Environmental remediation charge (3)	—		—			6.4		—
Legal and transaction costs (4)	0.8		—			1.3		—
Southbridge Landfill closure charge	$	0.8	$	—	—	$	64.9	$	—

(1)

We performed a test of recoverability under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 360, which indicated that the carrying value of our asset group that includes the Southbridge Landfill was no longer recoverable and, as a result, the asset group was assessed for impairment with an impairment charge allocated to the long-lived assets of the Southbridge Landfill in accordance with FASB ASC 360.


(2)	We wrote-off deferred costs associated with Southbridge Landfill permitting activities no longer deemed viable.


(3)	We recorded an environmental remediation charge associated with the future installation of a municipal waterline.


(4)	We incurred legal and other transaction costs associated with various matters as part of the Southbridge Landfill closure.

Other Expenses

Interest Expense, net

Our interest expense, net decreased $(3.4) million quarterly and $(10.6) million year-to-date due to lower average debt balances and changes to our capitalization structure. Specifically, since December 31, 2015 we completed the following transactions:


•	we completed the issuance of $15.0 million of New York State Environmental Facilities Corporation Solid Waste Disposal Revenue Bonds Series 2014R-2 (“New York Bonds 2016”) in June 2016;

•

we completed the refinancing of our senior secured asset-based revolving credit and letter of credit facility ("ABL Facility") with our credit facility, which consists of a $350.0 million term loan B facility ("Term Loan B Facility") and a $160.0 million revolving line of credit facility ("Revolving Credit Facility" and, together with the Term Loan B Facility, the "Credit Facility") and repaid in full our ABL Facility in October 2016;


•	we repurchased or redeemed, as applicable, $366.1 million of our most expensive debt, the 7.75% senior subordinated notes due February 2019 ("2019 Notes"), between June 2016 and October 2016;

•

we remarketed $3.6 million aggregate principal amount of Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-1 (“FAME Bonds 2005R-1”) and $21.4 million aggregate principal amount of Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-2 (“FAME Bonds 2005R-2”) into one series of $25.0 million aggregate principal amount of Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-3 (“FAME Bonds 2005R-3”) in February 2017; and


•	we entered into the first amendment ("Repricing Amendment") to our Term Loan B Facility and Revolving Credit Facility, which decreased the applicable interest margin for our Term Loan B Facility by 25 basis points for both LIBOR borrowings and base rate borrowings in April 2017.

Loss on Debt Extinguishment

We recorded a loss on debt extinguishment of $0.0 million and $0.5 million in the three and nine months ended September 30, 2017, respectively, as compared to a loss on debt extinguishment of $0.2 million and $0.7 million during the three and nine months ended September 30, 2016, respectively, associated with the following transactions:


•	the write-off of debt issuance costs in connection with the Repricing Amendment in the quarter ended June 30, 2017;


•	the write-off of debt issuance costs in connection with the remarketing of the FAME Bonds 2005R-1 and the FAME Bonds 2005R-2 into FAME Bonds 2005R-3 in the quarter ended March 31, 2017; and


•	the repurchase price premium and write-off of debt issuance costs and unamortized original issue discount associated with the early redemption, repurchase and retirement of partial portions of our 2019 Notes in the three and nine months ended September 30, 2016.

Provision for Income Taxes

Income taxes decreased $(0.1) million quarterly and increased $0.2 million year-to-date from a provision for income taxes of $0.3 million and $0.3 million in the three and nine months ended September 30, 2016, respectively. The provision for income taxes in the nine months ended September 30, 2017 and September 30, 2016 included $0.4 million and $0.5 million, respectively, of deferred tax provision due mainly to an increase in the deferred tax liability for indefinite lived assets, offset in the nine months ended September 30, 2017 in part by additional minimum tax credit carryforward with no expiration and requiring no valuation allowance. Since we cannot determine when the deferred tax liability related to indefinite lived assets will reverse, that portion of the deferred tax provisions cannot be used as a future source of taxable income against which to benefit deferred tax assets.

Eastern Region

Operating results increased $1.4 million quarterly and decreased $(61.1) million year-to-date. Excluding the impact of the Southbridge Landfill closure charge, our operating performance in the three and nine months ended September 30, 2017 improved due to the revenue growth outlined above and the following cost changes:

Cost of operations: Cost of operations increased $1.9 million quarterly and $4.1 million year-to-date due to the following:


•	higher hauling and transportation costs associated with higher collection volumes; and


•	higher direct labor costs associated with higher collection volumes, customer growth related to several new municipal contracts, and higher healthcare costs of $0.7 million year-to-date.

General and administration: General and administration expense increased $1.0 million quarterly and $1.4 million year-to-date due to higher shared overhead costs associated with an increase in healthcare costs year-to-date and higher equity compensation expense, partially offset by lower bad debt expense.

Depreciation and amortization: Depreciation and amortization expense decreased $(1.2) million quarterly and $(2.6) million year-to-date due to lower landfill amortization expense associated with lower landfill volumes at the Southbridge Landfill and the North Country Environmental Services landfill ("NCES Landfill") and changes to the asset retirement obligation amortization rate at the NCES Landfill.

Southbridge Landfill Closure Charge: In June 2017, we initiated the plan to cease operations of the Southbridge Landfill. Accordingly, in the quarter ended June 30, 2017, we recorded a $64.1 million charge associated with the closure of the Southbridge Landfill. Additionally, in the three months ended September 30, 2017, we recorded a charge of $0.8 million for legal costs associated with various matters as a part of the Southbridge Landfill closure. For additional information, see Note 7, Commitments and Contingencies to our consolidated financial statements included under Part I, Item 1 of this Quarterly Report on Form 10-Q.

Western Region

Operating income increased $0.2 million quarterly and $1.8 million year-to-date as our operating performance in the three and nine months ended September 30, 2017 improved due to the revenue growth outlined above and the following cost changes:

Cost of operations: Cost of operations increased $2.4 million quarterly and $7.8 million year-to-date due to the following:


•	higher disposal costs associated with higher transfer station volumes and increased third-party disposal pricing;


•	higher direct labor costs year-to-date associated with increased labor costs and increased healthcare costs of $0.7 million;


•	higher direct operational costs associated with increased leachate disposal and landfill operating costs due to; increased rainfall through early summer and the timing of various landfill construction projects; and higher host community fees associated with increased volumes at certain of our landfills; and


•	higher fleet maintenance costs; partially offset by


•	lower hauling and transportation costs associated with decreased transportation services provided.

General and administration: General and administration expense increased $1.4 million quarterly and $1.7 million year-to-date as higher shared overhead costs associated with an increase in healthcare costs and higher equity compensation expense were partially offset by lower wages and personnel costs.

Depreciation and amortization: Depreciation and amortization expense increased $1.6 million quarterly and $2.4 million year-to-date due to higher landfill amortization expense (associated with the higher landfill volumes, combined with the volume mix and changes to landfill amortization rates as a result of changes in cost estimates and other assumptions with our landfills) more than offsetting lower depreciation expense attributed to the timing of capital expenditures and related make-up of fixed assets.

Recycling

Operating income decreased $(0.9) million quarterly and increased $2.4 million year-to-date. Our operating performance in the three and nine months ended September 30, 2017 was impacted by the revenue growth outlined above and the following cost changes:

Cost of operations: Cost of operations increased $2.0 million quarterly and $6.3 million year-to-date due to the following:


•	higher third-party purchased material costs due to higher commodity prices on average year-over-year, accentuated in the quarter by the significant sequential decline in commodity pricing from August to September, which resulted in higher purchased materials costs based on trailing contractual calculations; and


•	higher labor and related benefit costs associated with higher healthcare costs year-to-date, higher volumes, and higher product quality standards from commodity buyers resulting in lower throughput and additional manpower.

General and administration: General and administration expense increased $0.5 million quarterly and $1.0 million year-to-date due primarily to higher labor costs, including incentive compensation, and higher shared overhead costs associated with an increase in healthcare costs year-to-date and higher equity compensation expense.

Other

Operating income increased $0.2 million quarterly and decreased $(0.4) million year-to-date based on the following:


•	lower operating performance of our Organics line-of-business, as lower operating costs did not offset the decline in commodity volumes and higher disposal costs due to the use of alternative disposal sites; and


•	improved operating performance of our Customer Solutions line-of-business, as increased volumes outweighed higher cost of operations associated with increased purchased material, hauling and transportation, and healthcare costs.

Liquidity and Capital Resources

We continually monitor our actual and forecasted cash flows, our liquidity, and our capital requirements in order to properly manage our cash needs based on the capital intensive nature of our business. Our capital requirements include fixed asset purchases (including capital expenditures for vehicles), debt servicing, landfill development and cell construction, landfill site and cell closure, as well as acquisitions. We generally meet our liquidity needs from operating cash flows and borrowings from our Revolving Credit Facility.

As part of our decision to cease operations at the Southbridge Landfill as discussed in Note 7, Commitments and Contingencies to our consolidated financial statements included under Part I, Item 1 of this Quarterly Report on Form 10-Q, we assessed the estimated costs and timing of cash flows associated with remaining capital expenditures, environmental remediation, and final capping, closure and post-closure activities at the Southbridge Landfill. We expect cash outflows in the next five years associated with these activities to be approximately $21.0 million and we do not believe that this will negatively impact our liquidity during this time. In addition, we estimate that over $52.0 million in additional tax deductions related to ceasing operations will be recognized in the next five years. Furthermore, we do not believe that ceasing operations at the Southbridge Landfill will impact our future operational activities in a manner that will have a material impact to our results of operations, our cash flows and our financial condition.

A summary of the most significant items affecting the change in our operating cash flows follows:

Improved operational performance in the nine months ended September 30, 2017 as compared to the nine months ended September 30, 2016 due to the following:


•	higher revenues of $26.9 million driven by our Recycling line-of-business, our collection line-of-business, our Western region disposal line-of-business and our Customer Solutions line-of-business; partially offset by


•	higher cost of operations of $16.6 million driven by higher third-party direct costs, higher labor and related benefit costs, including significant healthcare cost increases, and higher direct operational costs; and


•	higher general and administration expenses of $2.9 million driven by higher labor and related benefit costs, including significant healthcare cost increases.

The improved cash flow impact associated with the changes in our assets and liabilities, net of effects of acquisitions and divestitures, which are affected by both cost changes and the timing of payments, in the nine months ended September 30, 2017 as compared to the nine months ended September 30, 2016 was the result of the following:


•	lower cash outflows associated with cash interest payments running through accrued expenses and other liabilities; and


•	lower cash outflows associated with prepaid expenses, inventories and other assets; partially offset by


•	higher cash outflows associated with accrued payroll and incentive compensation;


•	lower cash inflows associated with accounts receivable; and


•	higher cash outflows associated with accounts payable.

We acquired three solid waste collection lines-of-business in the nine months ended September 30, 2017 for total consideration of $6.3 million, including $3.5 million in cash, as compared to the nine months ended September 30, 2016, when we acquired three transfer stations in our Western region for total consideration of $2.8 million, including $2.4 million in cash.

Capital expenditures. Capital expenditures were $5.8 million higher in the nine months ended September 30, 2017 as compared to the nine months ended September 30, 2016 primarily due to timing differences with various landfill development projects and business growth.

Payments on landfill operating lease contracts. Landfill operating lease payments decreased $(0.9) million in the nine months ended September 30, 2017 as compared to the nine months ended September 30, 2016 due to the timing of payments at certain of our landfills based on the terms of the operating lease contracts.

Proceeds from the sale of property and equipment. Proceeds from the sale of property and equipment decreased $(0.3) million in the nine months ended September 30, 2017 as compared to the nine months ended September 30, 2016 due to the timing and make-up of various asset sales.

Net cash used in financing activities.

A summary of the most significant items affecting the change in our financing cash flows follows:

Debt activity. We had an increase in both debt borrowings of $5.7 million and debt payments of $23.1 million in the nine months ended September 30, 2017 associated primarily with the following:


•	the pay down of $28.1 million of long-term debt under the Credit Facility in the nine months ended September 30, 2017;


•	the remarketing of the FAME Bonds 2005R-1 and the FAME Bonds 2005R-2 into the $25.0 million FAME Bonds 2005R-3 in the nine months ended September 30, 2017;


•	the issuance by the New York State Environmental Facilities Corporation of the New York Bonds 2016 in the nine months ended September 30, 2016; and


•	the repurchase or redemption, as applicable, and retirement of $24.7 million aggregate principal amount of the 2019 Notes in the nine months ended September 30, 2016 in order to maximize interest savings by paying down our most expensive debt.

Payments of debt issuance costs. We made $1.5 million of debt issuance cost payments in the nine months ended September 30, 2017 related to the Repricing Amendment and the remarketing of the FAME Bonds 2005R-1 and the FAME Bonds 2005R-2 into the FAME Bonds 2005R-3 as compared to $0.7 million in the nine months ended September 30, 2016 related primarily to the issuance of the New York Bonds 2016.

Proceeds from the exercise of share based awards. We received $1.0 million of cash receipts associated with the exercise of stock options in the nine months ended September 30, 2017.

Change in restricted cash. In the nine months ended September 30, 2016, we obtained $3.0 million of restricted cash from the issuance of $15.0 million aggregate principal amount of New York Bonds 2016 and subsequently used these funds to pay down ABL Facility borrowings for costs incurred to fund certain capital projects in the state of New York. We also used the remaining $1.3 million of restricted cash associated with the issuance of Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2015 (“FAME Bonds 2015”) in the nine months ended September 30, 2016 to pay down ABL Facility borrowings for costs incurred to fund certain capital projects in the state of Maine.

Outstanding Long-Term Debt

Credit Facility

In the quarter ended June 30, 2017, we entered into the Repricing Amendment to our Credit Facility agreement. The Repricing Amendment decreased the applicable interest margin for our Term Loan B Facility by 25 basis points for both LIBOR borrowings and base rate borrowings. The applicable interest margin will continue to be determined based on our consolidated net leverage ratio. The applicable interest rate will be reduced to 2.50% for LIBOR borrowings (with a 1.00% LIBOR floor), and 1.50% for base rate borrowings upon us reaching a consolidated net leverage ratio of 3.75x or less. Based on our consolidated net leverage ratio of 3.71x for the twelve months ended September 30, 2017, we expect the applicable interest rate to be reduced to 2.50% for LIBOR borrowings (with a 1.00% floor) and 1.50% for base rate borrowings effective upon the acceptance of our covenant compliance certificate that we expect to provide to the administrative agent for the Credit Facility on November 3, 2017.

As of September 30, 2017, we had outstanding $348.3 million aggregate principal amount of borrowings under our Term Loan B Facility and $36.3 million aggregate principal amount of borrowings under our Revolving Credit Facility. The Term Loan B Facility has a 7-year term and bears interest at a rate of LIBOR plus 2.75% per annum (with a 1.00% LIBOR floor) as of September 30, 2017. The Revolving Credit Facility has a 5-year term and bears interest at a rate of LIBOR plus 2.75% per annum as of September 30, 2017, which can be adjusted from an applicable rate of LIBOR plus 2.50% to 3.25% depending on our consolidated net leverage ratio. We are also required to make scheduled quarterly payments of $0.9 million on the Term Loan B Facility in March, June, September and December of each year until maturity in October 2023. Our Credit Facility is guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries and secured by substantially all of our assets. As of September 30, 2017, further advances were available under the Revolving Credit Facility in the amount of $100.8 million. This available amount is net of outstanding irrevocable letters of credit totaling $22.9 million as of September 30, 2017, at which date no amount had been drawn. We have the right to request, at our discretion, an increase in the amount of loans under the Credit Facility by an aggregate amount of $100.0 million, subject to the terms and conditions set forth in the Credit Facility agreement.

The Credit Facility agreement requires us to maintain a minimum interest coverage ratio and a maximum consolidated net leverage ratio, to be measured at the end of each fiscal quarter. As of September 30, 2017, we were in compliance with all financial covenants contained in the Credit Facility agreement as follows:



	Twelve Months Ended September 30, 2017	Covenant Requirement at September 30, 2017
Maximum consolidated net leverage ratio (1)	3.71	5.375
Minimum interest coverage ratio	5.68	2.50

(1)

The maximum consolidated net leverage ratio is calculated as consolidated funded debt, net of unencumbered cash and cash equivalents in excess of $2.0 million (calculated at $500.0 million as of September 30, 2017, or $500.3 million of consolidated funded debt less $0.3 million of cash and cash equivalents in excess of $2.0 million as of September 30, 2017), divided by minimum consolidated EBITDA. Minimum consolidated EBITDA is based on operating results for the twelve months preceding the measurement date of September 30, 2017. Consolidated funded debt, net of unencumbered cash and cash equivalents in excess of $2.0 million, and minimum consolidated EBITDA are non-GAAP financial measures that should not be considered an alternative to any measure of financial performance calculated and presented in accordance with generally accepted accounting principles in the United States. A reconciliation of net cash provided by operating activities to minimum consolidated EBITDA is as follows (in millions):



	Twelve Months Ended September 30, 2017
Net cash provided by operating activities	$	103.5
Changes in assets and liabilities, net of effects of acquisitions and divestitures	4.4
Gain on sale of property and equipment	0.1
Environmental remediation charge	(0.9		)
Loss on debt extinguishment	(13.5		)
Stock based compensation	(5.8		)
Southbridge Landfill non-cash charge	(63.5		)
Interest expense, less amortization of debt issuance costs and discount on long-term debt	25.5
Provision for income taxes, net of deferred taxes	0.3
Adjustments as allowed by the Credit Facility agreement	84.6
Minimum consolidated EBITDA	$	134.7

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

As of September 30, 2017, we were in compliance with the covenants contained in the Credit Facility agreement. An event of default under any of our debt agreements could permit some of our lenders, including the lenders under the Credit Facility, to declare all amounts borrowed from them to be immediately due and payable, together with accrued and unpaid interest, or, in the case of the Credit Facility, terminate the commitment to make further credit extensions thereunder, which could, in turn, trigger cross-defaults under other debt obligations. If we were unable to repay debt to our lenders, or were otherwise in default under any provision governing our outstanding debt obligations, our secured lenders could proceed against us and against the collateral securing that debt.

Based on the seasonality of our business, operating results in the late fall, winter and early spring months are generally lower than the remainder of our fiscal year. Given the cash flow impact that this seasonality, the capital intensive nature of our business and the timing of debt payments has on our business, we typically incur higher debt borrowings in order to meet our liquidity needs during these times. Consequently, our availability and performance against our financial covenants may tighten during these times as well.

Tax-Exempt Financings

New York Bonds. As of September 30, 2017, we had outstanding $40.0 million aggregate principal amount of Solid Waste Disposal Revenue Bonds Series 2014 ("New York Bonds 2014") and New York Bonds 2016 issued by the New York State Environmental Facilities Corporation under the indenture dated December 1, 2014 (collectively, the “New York Bonds”). The New York Bonds 2014 accrue interest at 3.75% per annum through December 1, 2019, at which time they may be converted from a fixed rate to a variable rate. The New York Bonds 2016 accrue interest at 3.125% per annum through May 31, 2026, at which time they may be converted from a fixed rate to a variable rate. The New York Bonds, which are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, require interest payments on June 1 and December 1 of each year and mature on December 1, 2044. We borrowed the proceeds of the New York Bonds to finance or refinance certain capital projects in the state of New York and to pay certain costs of issuance of the New York Bonds.

Maine Bonds. In the quarter ended March 31, 2017, we completed the remarketing of $3.6 million aggregate principal amount of FAME Bonds 2005R-1 and $21.4 million aggregate principal amount of FAME Bonds 2005R-2 into one series of $25.0 million aggregate principal amount of FAME Bonds 2005R-3. As of September 30, 2017, we had outstanding $25.0 million aggregate principal amount of FAME Bonds 2005R-3. The FAME Bonds 2005R-3, which are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 5.25% per annum, and interest is payable semiannually in arrears on February 1 and August 1 of each year until such bonds mature on January 1, 2025.

As of September 30, 2017, we had outstanding $15.0 million aggregate principal amount of FAME Bonds 2015. The FAME Bonds 2015, which are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 5.125% per annum through August 1, 2025, at which time they may be converted from a fixed to a variable rate, and interest is payable semiannually in arrears on February 1 and August 1 of each year. An additional $15.0 million aggregate principal amount of FAME Bonds 2015 may be offered under the same indenture in the future. The FAME Bonds 2015 mature on August 1, 2035. We borrowed the proceeds of the offering of the FAME Bonds 2015 to finance or refinance the costs of certain of our solid waste landfill facilities and solid waste collection, organics and transfer, recycling and hauling facilities, and to pay certain costs of the issuance of the FAME Bonds 2015.

Vermont Bonds. As of September 30, 2017, we had outstanding $16.0 million aggregate principal amount Vermont Economic Development Authority Solid Waste Disposal Long-Term Revenue Bonds Series 2013 (“Vermont Bonds”). The Vermont Bonds, which are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 4.75% per annum through April 1, 2018, at which time they may be converted from a fixed rate to a variable rate, and interest is payable semiannually in arrears on April 1 and October 1 of each year. The Vermont Bonds mature on April 1, 2036. We borrowed the proceeds of the Vermont Bonds to repay borrowings under our Senior Credit Facility for qualifying property, plant and equipment assets purchased in the state of Vermont.

New Hampshire Bonds. As of September 30, 2017, we had outstanding $11.0 million aggregate principal amount of Solid Waste Disposal Revenue Bonds Series 2013 issued by the Business Finance Authority of the State of New Hampshire (“New Hampshire Bonds”). The New Hampshire Bonds, which are unsecured and guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries, accrue interest at 4.00% per annum through October 1, 2019, at which time they may be converted from a fixed rate to a variable rate, and interest is payable in arrears on April 1 and October 1 of each year. The New Hampshire Bonds mature on April 1, 2029. We borrowed the proceeds of the New Hampshire Bonds to repay borrowings under our Senior Credit Facility for qualifying property, plant and equipment assets purchased in the state of New Hampshire.

Shelf Registration

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

Inflation

Although inflationary increases in costs have affected our historical operating margins, we believe that inflation generally has not had a significant impact on our operating results. Consistent with industry practice, most of our contracts provide for a pass-through of certain costs to our customers, including increases in landfill tipping fees and in some cases fuel costs, intended to mitigate the impact of inflation on our operating results. We have also implemented a number of operating efficiency

programs that seek to improve productivity and reduce our service costs, and a fuel surcharge, which is designed to recover escalating fuel price fluctuations above an annually reset floor. Based on these implementations, we believe we should be able to sufficiently offset most cost increases resulting from inflation. However, competitive factors may require us to absorb at least a portion of these cost increases. Additionally, management’s estimates associated with inflation have had, and will continue to have, an impact on our accounting for landfill and environmental remediation liabilities.

Regional Economic Conditions

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

Seasonality and Severe Weather

Our transfer and disposal revenues historically have been higher in the late spring, summer and early fall months. This seasonality reflects lower volumes of waste in the late fall, winter and early spring months because:


•	the volume of waste relating to C&D activities decreases substantially during the winter months in the northeastern United States; and


•	decreased tourism in Vermont, New Hampshire, Maine and eastern New York during the winter months tends to lower the volume of waste generated by commercial and restaurant customers, which is partially offset by increased volume from the ski industry.

Because certain of our operating and fixed costs remain constant throughout the fiscal year, operating income is impacted by a similar seasonality. Our operations can also be adversely affected by periods of inclement or severe weather, which could increase our operating costs associated with the collection and disposal of waste, delay the collection and disposal of waste, reduce the volume of waste delivered to our disposal sites, increase the volume of waste collected under our existing contracts (without corresponding compensation), decrease the throughput and operating efficiency of our materials recycling facilities, or delay construction or expansion of our landfill sites and other facilities. Our operations can also be favorably affected by severe weather, which could increase the volume of waste in situations where we are able to charge for our additional services provided.

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

Limitations on Ownership of Notes

Pursuant to the provisions of the Credit Facility agreement and the FAME Bonds 2015, FAME Bonds 2005R-3, New Hampshire Bonds, New York Bonds and Vermont Bonds, no lender under the Credit Facility or beneficial holder of the FAME Bonds 2015, FAME Bonds 2005R-3, New Hampshire Bonds, New York Bonds and/or Vermont Bonds is permitted to knowingly lend under the Credit Facility agreement or acquire FAME Bonds 2015, FAME Bonds 2005R-3, New Hampshire Bonds, New York Bonds and/or Vermont Bonds if such lender or person would hold 10% or more of the consolidated debt for which relevant subsidiaries of ours are obligated (and must dispose of the loans under the Credit Facility agreement, FAME Bonds 2015, FAME Bonds 2005R-3, New Hampshire Bonds, New York Bonds and/or Vermont Bonds or other debt of ours to the extent such lender or 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 lenders under the Credit Facility agreement or beneficial holders of the FAME Bonds 2015, FAME Bonds 2005R-3, New Hampshire Bonds, New York Bonds and Vermont Bonds, in each quarterly and annual report, the dollar amount of our debt that would serve as the threshold for evaluating a beneficial holder’s compliance with these ownership restrictions. As of September 30, 2017, that dollar amount was $49.2 million.

Critical Accounting Policies and Estimates

The preparation of our financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities, as applicable, at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an on-going basis, management evaluates its estimates and judgments which are based on historical experience and on various other factors that are believed to be reasonable under the circumstances. The results of their evaluation form the basis for making judgments about the carrying

values of assets and liabilities. Actual results may differ from these estimates under different assumptions and circumstances. Our significant accounting policies are more fully discussed in Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

New Accounting Pronouncements

For a description of the new accounting standards that may affect us, see Note 2 to our consolidated financial statements included under Part I, Item 1 of this Quarterly Report on Form 10-Q.


ITEM 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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

Interest Rate Volatility

In the quarter ended March 31, 2017, we entered into three interest rate derivative agreements to hedge interest rate risk associated with the variable rate portion of our long-term debt. The total notional amount of these agreements is $60.0 million and requires us to receive interest based on changes in the 1-month LIBOR index with a 1.0% floor and pay interest at a weighted average rate of approximately 1.95%. Two of the agreements, with a total notional amount of $35.0 million, mature in February 2021, and the final agreement, with a total notional amount of $25.0 million, matures in February 2022.

We designated the three interest rate derivative agreements as effective cash flow hedges upon inception, and therefore the change in fair value is recorded in our stockholders’ deficit as a component of accumulated other comprehensive loss and included in interest expense at the same time as interest expense is affected by the hedged transactions. Differences paid or received over the life of the agreements are recorded as additions to or reductions of interest expense on the underlying debt.

We had interest rate risk relating to approximately $324.6 million of long-term debt at September 30, 2017. The weighted average interest rate on the variable rate portion of long-term debt was approximately 4.0% at September 30, 2017. Should the average interest rate on the variable rate portion of long-term debt change by 100 basis points, we estimate that our quarterly interest expense would change by up to approximately $0.8 million. The remainder of our long-term debt is at fixed rates and not subject to interest rate risk.

Commodity Price Volatility

Through our Recycling operation, we market a variety of materials, including fibers such as old corrugated cardboard and old newsprint, plastics, glass, ferrous and aluminum metals. We may use a number of strategies to mitigate impacts from commodity price fluctuations including: (1) charging collection customers a floating sustainability recycling adjustment fee to offtake recycling commodity risks; (2) in-bound material recovery facilities ("MRF") customers receiving a revenue share or indexed materials purchases in higher commodity price markets, or charging these same customers a processing cost or tipping fee per ton in lower commodity price markets; (3) selling recycling commodities to out-bound MRF customers through floor price or fixed price agreements; or (4) entering into fixed price contracts or hedges that mitigate the variability in cash flows generated from the sales of recycled paper at floating prices. We do not use financial instruments for trading purposes and are not a party to any leveraged derivatives. As of September 30, 2017, we were not party to any commodity hedging agreements.

In October 2017, the Official Board Market released commodity pricing data that indicated a steep decline in near-term commodity prices. As a result, we believe that it is reasonably possible that our average commodity revenue per ton will drop by approximately 40% from September 2017 to October 2017. Should commodity prices change by 40%, we estimate that our quarterly operating income margin would change by approximately $0.8 million based on the observed impact of commodity price changes on operating income margin. Our sensitivity to changes in commodity prices is complex because each customer contract is unique relative to revenue sharing, tipping or processing fees and other arrangements. The above operating income impact may not be indicative of future operating results and actual results may vary materially.


ITEM 4.	CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures. Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2017. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of September 30, 2017, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in internal controls over financial reporting. No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the three months ended September 30, 2017 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II.


ITEM 1.	LEGAL PROCEEDINGS

Legal Proceedings

Environmental Remediation Liability

Southbridge Recycling & Disposal Park, Inc.

In October 2015, our Southbridge Recycling and Disposal Park, Inc. (“SRD”) subsidiary reported to the Massachusetts Department of Environmental Protection (“MADEP”) results of analysis of samples collected pursuant to our existing permit from private drinking water wells located near the Town of Southbridge, Massachusetts (“Town”) Landfill (“Southbridge Landfill”), which is operated by SRD. Those results indicated the presence of contaminants above the levels triggering notice and response obligations under MADEP regulations. In response to those results, we are carrying out an Immediate Response Action pursuant to Massachusetts General Law Chapter 21E (the "Charlton 21E Obligations") pursuant to state law. Further, we have implemented a plan to analyze and better understand the groundwater near the Southbridge Landfill and we are investigating with the objective of identifying the source or sources of the elevated levels of contamination measured in the well samples. If it is determined that some or all of the contamination originated at the Southbridge Landfill, we will work with the Town, the Southbridge Landfill owner and the former operator of an unlined portion of the Southbridge Landfill, which was used prior to our operation of a double-lined portion of the Southbridge Landfill commencing in 2004, to evaluate and allocate the liabilities related to the Charlton 21E Obligations. In July 2016, we sent correspondence to the Town pursuant to Chapter 21E of Massachusetts General Laws demanding that the Town reimburse us for the environmental response costs we had spent and that the Town be responsible for all such costs in the future, as well as any other costs or liabilities resulting from the release of contaminants from the unlined portion of the Southbridge Landfill. The Town responded in September 2016, denying that the Southbridge Landfill is the source of such contamination, and claiming that if it is, that we may owe an indemnity to the Town pursuant to the Operating Agreement between us and the Town dated May 29, 2007, as amended. We entered into a Tolling Agreement with the Town to delay any further administrative or legal actions until our work with MADEP more specifically defines the parties’ responsibilities for the Charlton 21E Obligations, if any. Please see below for further discussion of our relationship with the Town regarding the Charlton 21E Obligations.

remediation, diminution of property values, compensation for lost use and enjoyment of properties, enjoinment of further operation of the Southbridge Landfill, and costs of litigation, plus interest on any damage award, on behalf of the Residents. We believe the Litigation to be factually inaccurate, and without legal merit, and we and SRD intend to vigorously defend the Litigation. Nevertheless, we believe it is reasonably possible that a loss will occur as a result of the Litigation although an estimate of loss cannot be reasonably provided at this time due to the infancy of this matter. We also continue to believe the Town should be responsible for costs or liabilities associated with the Litigation relative to alleged contamination originating from the unlined portion of the Southbridge Landfill, although there can be no assurance that we will not be required to incur some or all of such costs and liabilities.

We entered into an Administrative Consent Order on April 26, 2017 (the “ACO”), with MADEP, the Town, and the Town of Charlton, committing us to equally share the costs with MADEP, of up to $10.0 million ($5.0 million each) for the Town to install a municipal waterline in the Town of Charlton ("Waterline"). Upon satisfactory completion of that Waterline, and other matters covered by the ACO, we and the Town will be released by MADEP from any future responsibilities for the Charlton 21E Obligations. We also entered into an agreement with the Town on April 28, 2017 entitled the “21E Settlement and Water System Construction Funding Agreement” (the “Waterline Agreement”), wherein we and the Town released each other from claims arising from the Charlton 21E Obligations. Pursuant to the Waterline Agreement, the Town will issue a twenty (20) year bond for our portion of the Waterline costs (up to $5.0 million). We have agreed to reimburse the Town for periodic payments under such bond.

On June 13, 2017, Town voters rejected a non-binding ballot initiative intended to provide guidance to Town officials with respect to our pursuit of other landfill development opportunities at the Southbridge Landfill. Following such rejection by the Town voters, our board of directors and senior management determined after due consideration of all facts and circumstances that it is no longer likely that further development at the existing landfill site will generate an adequate risk adjusted return at the Southbridge Landfill, and accordingly we expect to cease operations at the Southbridge Landfill when no further capacity is available, expected by no later than December 31, 2018. We delivered correspondence to the Town to this effect on August 3, 2017, citing events of Change in Law and Force Majeure pursuant to our May 29, 2007 Extension Agreement with the Town ("Extension Agreement") and the impacts of such events on further expansion of the Southbridge Landfill. We have advised the Town that we see no economically feasible way to operate the Southbridge Landfill beyond its current permitted life. Following cessation of operations, we will proceed to conduct proper closure and other activities at the Southbridge Landfill in accordance with the Extension Agreement with the Town, and Federal, state and local law. We reached this conclusion after carefully evaluating the estimated future costs associated with the permitting, engineering and construction activities for the planned expansion of the Southbridge Landfill against the possible outcomes of the permitting process and the anticipated future benefits of successful expansions. Under the Extension Agreement, which we account for as an operating lease, there are potential contractual obligations and commitments, including future cash payments of $3.1 million and services that extend beyond the current useful life of the Southbridge Landfill. In accordance with FASB ASC 420 - Exit or Disposal Cost Obligations, a liability for costs to be incurred under a contract for its remaining term without economic benefit shall be recognized when we cease using the right conveyed by the contract. We may incur a loss associated with these potential contractual obligations upon cessation of operations at the Southbridge Landfill, when remaining capacity is exhausted by the placement of waste at the site. See Note 10, Other Items and Charges for information regarding the Southbridge landfill closure charge.

Potsdam Environmental Remediation Liability

On December 20, 2000, the State of New York Department of Environmental Conservation (“DEC”) issued an Order on Consent (“Order”) which named Waste-Stream, Inc. (“WSI”), our subsidiary, General Motors Corporation (“GM”) and Niagara Mohawk Power Corporation (“NiMo”) as Respondents. The Order required that the Respondents undertake certain work on a 25-acre scrap yard and solid waste transfer station owned by WSI in Potsdam, New York, including the preparation of a Remedial Investigation and Feasibility Study (“Study”). A draft of the Study was submitted to the DEC in January 2009 (followed by a final report in May 2009). The Study estimated that the undiscounted costs associated with implementing the preferred remedies would be approximately $10.2 million. On February 28, 2011, the DEC issued a Proposed Remedial Action Plan for the site and accepted public comments on the proposed remedy through March 29, 2011. We submitted comments to the DEC on this matter. In April 2011, the DEC issued the final Record of Decision (“ROD”) for the site. The ROD was subsequently rescinded by the DEC for failure to respond to all submitted comments. The preliminary ROD, however, estimated that the present cost associated with implementing the preferred remedies would be approximately $12.1 million. The DEC issued the final ROD in June 2011 with proposed remedies consistent with its earlier ROD. An Order on Consent and Administrative Settlement naming WSI and NiMo as Respondents was executed by the Respondents and DEC with an effective date of October 25, 2013. On January 29, 2016, a Cost-Sharing Agreement was executed between WSI, NiMo, Alcoa Inc. (“Alcoa”) and Reynolds Metal Company (“Reynolds”) whereby Alcoa and Reynolds elected to voluntarily participate in the onsite remediation activities at a combined 15% participant share. It is unlikely that any significant expenditures relating to onsite remediation will be incurred until the fiscal year ending December 31, 2019. WSI is jointly and severally liable with NiMo, Alcoa and Reynolds for the total cost to remediate.

ITEM 1A.	RISK FACTORS

Our business is subject to a number of risks, including those identified in Item 1A, “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, 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 September 30, 2017, there have been no material changes to the risk factors disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, except as set forth in the following paragraphs. We may disclose additional changes to our risk factors or disclose additional factors from time to time in our future filings with the SEC.

Our results of operations are affected by fluctuating commodity prices and market requirements for recyclable materials.

Our results of operations have been and will continue to be affected by changing purchase or resale prices or market requirements for recyclable materials. Our recycling business involves the purchase and sale of recyclable materials, some of which are priced on a commodity basis. The commodity markets continue to see ongoing negative pressure on pricing associated with the decline of the fiber market due to less use of paper products such as newspaper and office paper as a result of increased on-line reading. As a result of these market changes, domestic demand for various recycled fibers from mill buyers has steadily declined over the past decade, and as such we have exported more of these materials overseas to China. In 2017, China launched a campaign called “National Sword” which has imposed significant restrictions on the importation into China of recyclable materials, including imposing new quality standards for contaminants in recycled materials commencing January 1, 2018. Furthermore, China has not issued import licenses for its mills to import recycled commodities for 2018, resulting in a stoppage of essentially all imports into China of recycled commodities. These factors could have a significant impact on our business.

We seek to limit our exposure to fluctuating commodity prices through: our revenue sharing contracts that share commodity prices above a threshold level or charge a tipping fee below the threshold; our net commodity rate formula that allows us to pass back higher costs to sell commodities, including higher labor costs or equipment costs to meet new quality standards; our floating Sustainability Recycling Adjustment fee that passes back the cost of recycling to our collection customers; and as applicable the use of hedging agreements, floor price contracts and long-term supply contracts with customers. Although we have introduced these risk mitigation programs to help offset volatility in commodity prices and to offset higher labor or capital costs to meet more stringent contamination standards, we cannot provide assurance that we can use these programs with our customers in all circumstances or that they will mitigate these risks in an evolving recycling environment.

The waste industry is subject to extensive government regulations, including environmental regulations, and we incur substantial costs to comply with such regulations. Failure to comply with environmental or other regulations, as well as enforcement actions and litigation arising from an actual or perceived breach of such regulations, could subject us to fines, penalties, and judgments, and impose limits on our ability to operate and expand.

We are subject to potential liability and restrictions under environmental laws, including those relating to transportation, recycling, treatment, storage and disposal of wastes, discharges of pollutants to air and water, and the remediation of contaminated soil, surface water and groundwater. The waste management industry has been and will continue to be subject to regulation, including permitting and related financial assurance requirements, as well as attempts to further regulate the industry, including efforts to regulate the emission of greenhouse gases. Our solid waste operations are subject to a wide range of federal, state and, in some cases, local environmental, odor and noise and land use restrictions. If we are not able to comply with the requirements that apply to a particular facility or if we operate without the necessary approvals or permits, we could be subject to administrative or civil, and possibly criminal, fines and penalties, and we may be required to spend substantial capital to bring an operation into compliance, to temporarily or permanently discontinue activities, and/or take corrective actions, possibly including removal of landfilled materials. Those costs or actions could be significant to us and affect our results of operations, cash flows, and available capital. Environmental and land use laws also affect our ability to expand and, in the case of our solid waste operations, may dictate those geographic areas from which we must, or, from which we may not, accept solid waste. Those laws and regulations may limit the overall size and daily solid waste volume that may be accepted by a solid waste operation. If we are not able to expand or otherwise operate one or more of our facilities because of limits imposed under such laws, we may be required to increase our utilization of disposal facilities owned by third-parties, which could reduce our revenues and/or operating margins.

In addition to complying with environmental laws and regulations, we are required to obtain government permits to operate our facilities, including all of our landfills. There is no guarantee that we will be able to obtain the requisite permits and, even if we could, that any permit (and any existing permits we currently hold) will be renewed or modified as needed to fit our business needs. Localities where we operate generally seek to regulate some or all landfill and transfer station operations, including siting and expansion of operations. The laws adopted by municipalities in which our landfills and transfer stations are located

may limit or prohibit the expansion of a landfill or transfer station, as well as the amount of solid waste that we can accept at the landfill or transfer station on a daily, quarterly or annual basis, and any effort to acquire or expand landfills and transfer stations, which typically involves a significant amount of time and expense. We may not be successful in obtaining new landfill or transfer station sites or expanding the permitted capacity of any of our current landfills and transfer stations. If we are unable to develop additional disposal and transfer station capacity, our ability to achieve economies from the internalization of our waste stream will be limited. If we fail to receive new landfill permits or renew existing permits, we may incur landfill asset impairment and other charges associated with accelerated closure.

We have historically grown through acquisitions, may make additional acquisitions in the future, and we have tried and will continue to try to evaluate and limit environmental risks and liabilities presented by businesses to be acquired prior to the acquisition. It is possible that some liabilities may prove to be more difficult or costly to address than we anticipate. It is also possible that government officials responsible for enforcing environmental laws may believe an issue is more serious than we expect, or that we will fail to identify or fully appreciate an existing liability before we become responsible for addressing it. Some of the legal sanctions to which we could become subject could cause the suspension or revocation of a permit, prevent us from, or delay us in, obtaining or renewing permits to operate or expand our facilities, or harm our reputation. As of September 30, 2017, we had recorded $5.9 million in environmental remediation liabilities for the estimated cost of our share of work associated with a consent order issued by the State of New York to remediate a scrap yard and solid waste transfer station owned by one of our acquired subsidiaries, including the recognition of accretion expense. There can be no assurance that the cost of such cleanup or that our share of that cost will not exceed our estimates.

In addition to the costs of complying with environmental laws and regulations, we incur costs defending against environmental litigation brought by government agencies and private parties. We are, and may be in the future, a defendant in lawsuits brought by parties alleging environmental damage, personal injury, and/or property damage, or seeking to overturn or prevent the issuance of an operating permit or authorization, all of which may result in us incurring significant liabilities.

In October 2015, our Southbridge Recycling and Disposal Park, Inc. (“SRD”) subsidiary reported to the Massachusetts Department of Environmental Protection (“MADEP”) results of analysis of samples collected pursuant to our existing permit from private drinking water wells located near the Town of Southbridge, Massachusetts (“Town”) Landfill (“Southbridge Landfill”), which is operated by SRD. Those results indicated the presence of contaminants above the levels triggering notice and response obligations under MADEP regulations. In response to those results, we are carrying out an Immediate Response Action pursuant to Massachusetts General Law Chapter 21E (the “Charlton 21E Obligations”) pursuant to state law. Further, we have implemented a plan to analyze and better understand the groundwater near the Southbridge Landfill and we are investigating with the objective of identifying the source or sources of the elevated levels of contamination measured in the well samples. If it is determined that some or all of the contamination originated at the Southbridge Landfill, we will work with the Town, the Southbridge Landfill owner and the former operator of an unlined portion of the Southbridge Landfill, which was used prior to our operation of a double-lined portion of the Southbridge Landfill commencing in 2004, to evaluate and allocate the liabilities related to the Charlton 21E Obligations. In July 2016, we sent correspondence to the Town pursuant to Chapter 21E of Massachusetts General Laws demanding that the Town reimburse us for the environmental response costs we had spent and that the Town be responsible for all such costs in the future, as well as any other costs or liabilities resulting from the release of contaminants from the unlined portion of the Southbridge Landfill. The Town responded in September 2016, denying that the Southbridge Landfill is the source of such contamination, and claiming that if it is, that we may owe an indemnity to the Town pursuant to the Operating Agreement between us and the Town dated May 29, 2007, as amended. We entered into a Tolling Agreement with the Town to delay any further administrative or legal actions until our work with MADEP more specifically defines the parties’ responsibilities for the Charlton 21E Obligations, if any.

In February 2016, we and the Town received a Notice of Intent to Sue under the Resource Conservation and Recovery Act (“RCRA”) from a law firm purporting to represent residents proximate to the Southbridge Landfill (“Residents”), indicating its intent to file suit against us on behalf of the Residents alleging the groundwater contamination originated from the Southbridge Landfill. In February 2017, we received an additional Notice of Intent to Sue from the National Environmental Law Center under the Federal Clean Water Act (“CWA”) and RCRA (collectively the “Acts”) on behalf of Environment America, Inc., d/b/a Environment Massachusetts, and Toxics Action Center, Inc., which have referred to themselves as the Citizen Groups. The Citizen Groups alleged that we had violated the Acts, and that they intended to seek appropriate relief in federal court for those alleged violations. On or about June 9, 2017, a lawsuit was filed against us, SRD and the Town in the United States District Court for the District of Massachusetts by the Citizen Groups and the Residents alleging violations of the Acts (the “Litigation”), and demanding a variety of remedies under the Acts, including fines, remediation, mitigation and costs of litigation, and remedies for violations of Massachusetts civil law related to personal and property damages, including remediation, diminution of property values, compensation for lost use and enjoyment of properties, enjoinment of further operation of the Southbridge Landfill, and costs of litigation, plus interest on any damage award, on behalf of the Residents.

We believe it is reasonably possible that a loss will occur as a result of the Litigation although an estimate of loss cannot be reasonably provided at this time due to the infancy of this matter.

We may not have sufficient insurance coverage for our environmental liabilities, such coverage may not cover all of the potential liabilities we may be subject to and/or we may not be able to obtain insurance coverage in the future at reasonable expense, or at all.

The conduct of our businesses is also subject to various other laws and regulations administered by federal, state and local governmental agencies, including tax laws, employment laws and competition laws, among others. New laws, regulations or governmental policy and their related interpretations, or changes in any of the foregoing, including taxes or other limitations on our services, may alter the environment in which we do business and, therefore, may impact our results or increase our costs or liabilities.

In certain jurisdictions, we are subject to compliance with specific obligations under competition laws due to our competitive position in those jurisdictions. For example, in May 2002, we entered into an assurance of discontinuance with the Vermont Attorney General’s Office concerning, among other matters, the conduct of our business in Vermont relating to certain contract terms applicable to our small commercial container customers. In August 2011, a revised final judgment of consent and order was entered by the Vermont Superior Court Washington Unit, Civil Division, as a result of some of our small commercial container customers having been mistakenly issued contracts that did not strictly comply with the terms of the assurance of discontinuance. Pursuant to the order, we paid a civil penalty in an aggregate amount of $1.0 million. In July 2014, we entered into an assurance of discontinuance with the office of the New York Attorney General in connection with certain of our commercial practices in certain specified counties in New York, pursuant to which we paid the State of New York a sum of $0.1 million. The assurances of discontinuance and order provide for certain restrictions on our customer contract terms, certain conditions on our business acquisitions, sales and market share and require us to maintain an internal compliance program. Failure to comply with these requirements or other laws or regulations could subject us to enforcement actions or financial penalties which could have a material adverse effect on our business.

EXHIBIT A

CASELLA WASTE SYSTEMS, INC.

Restricted Stock Unit Agreement

2016 Incentive Plan

Terms and Conditions


1.	Grant of Restricted Stock Units.

The Award is granted pursuant to and is subject to and governed by the Plan and the terms of this Agreement. It is a form of “RSU” as defined in the Plan. Unless otherwise defined in this Agreement, capitalized terms used herein shall have the same meaning as in the Plan. The shares of Common Stock that are issuable after the RSUs have been earned are referred to in this Agreement as “Shares.” The RSUs shall be granted to the Participant without payment of consideration (other than continuing services).


2.	Determination of Earned RSUs.

Unless otherwise provided in this Agreement or the Plan, shares will be earned on account of the RSUs in accordance with the following vesting schedule: 100% of the RSUs shall be earned on the first anniversary of the Grant Date. Any fractional number of RSUs resulting from application of the foregoing percentage(s) shall be rounded down to the nearest whole number of RSUs.


3.	Change in Control Event.

Notwithstanding the vesting schedule set forth in Section 2, immediately prior to a Change in Control Event (as defined in the Plan and provided that such event constitutes a “change in control event” within the meaning of Treasury Regulation Section 1.409A-3(i)(5)(i), to the extent required under Section 409A of the Code), the Participant shall be entitled to payment of all Shares.


4.	Cessation of Business Relationship.

(a) Definitions. For purposes of this Section:

(i) “Beneficiary” shall mean the last person or persons designated as such by the Participant in writing prior to the Participant’s death. If no such person survives the Participant, the Beneficiary shall be the Participant’s estate.

(ii) “Disability” shall have the meaning provided under Treasury Regulation Section 1.409A-3(i)(4)(i) and (iii).

(b) Death or Disability. If the Participant’s continuous service to the Company as a director, consultant or advisor (a “Business Relationship”) ceases as a result of the

Participant’s (i) death or (ii) Disability, the Participant (or the Participant’s Beneficiary in the event of the Participant’s death) shall be entitled to payment of all Shares.

(c) Other Cessation of Business Relationship. If the Participant’s Business Relationship ceases for any reason other than as described in Section 4(b), the RSUs which have not been earned pursuant to Sections 2 or 3 prior to such cessation will be forfeited without the payment of any consideration to the Participant, effective as of such cessation, except as provided in this Section.

5. Payment.

(a) Within 60 days following the date on which any RSUs are earned, the Company shall distribute to the Participant (or to the Participant’s Beneficiary in the event of death) the Shares represented by RSUs that were earned, subject to Section 11 hereof and upon the satisfaction of all other applicable conditions as to the RSUs; provided, however, that the Shares shall be distributed no later than the 15th day of the third month following the end of the Company’s taxable year; provided further, however, that the Shares may be distributed following the date contemplated in this Section to the extent permitted under Section 409A (“Section 409A”) of the Code without the payment becoming subject to, and being treated as “nonqualified deferred compensation” within the meaning of Section 409A (such as where the Company reasonably anticipates that the payment will violate federal securities laws or other applicable laws). Payment of any earned RSUs shall be made in whole Shares. Earned RSUs shall be rounded down to the nearest whole Share, and the Company shall pay the value of any fractional Shares to the Participant in cash on the basis of the fair market value per share of Common Stock on the date of distribution (determined by reference to the closing price of the Common Stock on the principal exchange on which the Common Stock trades on the date of distribution, or if such date is not a trading date, on the next preceding trading date).

(b) The Company shall not be obligated to issue Shares to the Participant upon the earning of any RSUs unless the issuance and delivery of such Shares shall comply with all relevant provisions of law and other legal requirements including, without limitation, any applicable federal, state or foreign securities laws and the requirements of any stock exchange upon which Shares may be listed.

(c) Anything in the foregoing to the contrary notwithstanding, RSUs granted under this Agreement may be suspended, delayed or otherwise deferred for any of the reasons contemplated in Sections 4 and 5 only to the extent such suspension, delay or deferral is permitted under Treas. Reg. §§1.409A-2(b)(7), 1.409A-1(b)(4)(ii) or successor provisions, or as otherwise permitted under Section 409A.

6. Option of Company to Deliver Cash.

Notwithstanding any of the other provisions of this Agreement, at the time when any RSUs are payable pursuant to Section 5, the Company may elect, in the sole discretion of the Committee, to deliver to the Participant in lieu of the Shares represented by RSUs that are then payable an equivalent amount of cash (determined by reference to the closing price of the Shares on the principal exchange on which the Shares trade on the applicable

payment date or if such date is not a trading date, on the next preceding trading date). Such payments shall be made no later than the deadline set forth in Section 5(a) hereof. If the Company elects to deliver cash to the Participant, the Company is authorized to retain such amount as is sufficient to satisfy any tax withholding obligations as set forth in Section 11 hereof.

7. Restrictions on Transfer.

(a) The Participant shall not sell, assign, transfer, pledge, hypothecate or otherwise encumber or dispose of any RSUs, either voluntarily or by operation of law. Any attempt to dispose of any RSUs in contravention of the above restriction shall be null and void and without effect.

(b) The Company shall not be required (i) to transfer on its books any of the RSUs that have been transferred in violation of any of the provisions set forth herein or (ii) to treat as the owner of such RSUs any transferee to whom such RSUs have been transferred in violation of any of the provisions contained herein.

8. No Obligation to Continue Business Relationship.

Neither the Plan, this Agreement, nor the grant of the RSUs imposes any obligation on the Company or its subsidiaries to have or continue a Business Relationship with the Participant.

9. No Rights as Stockholder.

The RSUs represent an unfunded, unsecured promise by the Company to deliver Shares or the value thereof in accordance with the terms of this Agreement. The Participant shall have no rights as a shareholder with respect to the Shares underlying the RSUs. The Participant shall have no right to vote or receive dividends with respect to any Shares underlying the RSUs unless and until such Shares are distributed to the Participant.

10. Adjustments for Capital Changes; Reorganization Event.

The Plan contains provisions covering the treatment of RSUs in a number of contingencies such as stock splits and mergers. Provisions in the Plan for such adjustments are applicable hereunder and are incorporated herein by reference. The treatment of the RSUs in connection with a Reorganization Event is governed by Section 10 of the Plan.

11. Withholding Taxes.

The Participant acknowledges and agrees that the Company has the right to deduct from payments of any kind otherwise due to the Participant any federal, state, local or other taxes of any kind required by law to be withheld with respect to the vesting of the RSUs. The Participant agrees that if under applicable law the Participant will owe taxes at such vesting date on the portion of the RSUs then vested the Company shall be entitled to immediate payment from the Participant of the amount of any tax required to be withheld

by the Company. The Company shall not deliver any shares of Common Stock to the Participant until it is satisfied that all required withholdings have been made.

12. Nature of Grant.

In accepting the RSUs, Participant acknowledges that: (a) the grant of the RSUs is voluntary and occasional and does not create any contractual or other right to receive future grants of RSUs, or benefits in lieu of RSUs even if RSUs have been granted repeatedly in the past; (b) all decisions with respect to future awards of RSUs, if any, will be at the sole discretion of the Company; (c) the future value of the underlying Shares is unknown and cannot be predicted with certainty; (d) in consideration of the award of RSUs, no claim or entitlement to compensation or damages shall arise from termination of the RSUs or any diminution in value of the RSUs or Shares received when the RSUs are earned resulting from the Participant’s termination of service by the Company or any subsidiary (for any reason whatsoever), and Participant irrevocably releases the Company and/or the subsidiary from any such claim that may arise; (e) in the event of involuntary termination of Participant’s service, Participant’s right to receive RSUs and vesting under the Plan, if any, will terminate effective as of the date that Participant is no longer actively performing services and will not be extended by any notice period mandated under local law or contract, and the Company shall have the exclusive discretion to determine when Participant is no longer actively performing services for purposes of the RSUs; (f) the Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding Participant’s participation in the Plan, or Participant’s acquisition or sale of the underlying Shares; and (g) Participant is hereby advised to consult with his or her own personal tax, legal and financial advisors regarding Participant’s participation in the Plan before taking any action related to the Plan.

13. Miscellaneous.

(a) Notices. All notices hereunder shall be in writing and shall be deemed given when sent by certified or registered mail, postage prepaid, return receipt requested, if to the Participant, to the address set forth on the cover sheet or at the most recent address shown on the records of the Company, and if to the Company, to the Company's principal office, attention of the Corporate Secretary.

(b) Entire Agreement; Modification. This Agreement (including the cover sheet) and the Plan constitutes the entire agreement between the parties relative to the subject matter hereof, and supersedes all other communications between the parties relating to the subject matter of this Agreement. This Agreement may be modified, amended or rescinded by the Committee as it shall deem advisable, subject to any requirement for shareholder approval imposed by applicable law or other applicable rules, including, without limitation, the rules of the stock exchange on which the Shares are listed. If the Committee determines that the Award terms could result in adverse tax consequences to the Participant, the Committee may amend this Agreement without the consent of the Participant in order to minimize or eliminate such tax treatment.

(c) Plan Governs. This Agreement is subject to all terms and provisions of the Plan. In the event of a conflict between one or more provisions of this Agreement and one or more provisions of the Plan, the provisions of the Plan will govern.

(d) Severability. The invalidity, illegality or unenforceability of any provision of this Agreement shall in no way affect the validity, legality or enforceability of any other provision.

(e) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the heirs, legatees, distributees, executors and administrators of the Participant and the successors and assigns of the Company.

(f) Participant’s Acceptance. The Participant is urged to read this Agreement carefully and to consult with his or her own legal counsel regarding the terms and consequences of this Agreement and the legal and binding effect of this Agreement. By virtue of his or her acceptance of this Agreement, the Participant is deemed to have accepted and agreed to all of the terms and conditions of this Award and the provisions of the Plan, including as binding, conclusive and final all decisions or interpretations of the Committee upon any questions arising under the Plan or this Award.

(g) Section 409A. This Agreement, the RSUs and payments made pursuant to this Agreement are intended to comply with or qualify for an exemption from the requirements of Section 409A and shall be construed consistently therewith and shall be interpreted in a manner consistent with that intention. Terms defined in the Agreement shall have the meanings given such terms under Section 409A if and to the extent required to comply with Section 409A. Notwithstanding any other provision of this Agreement, the Company reserves the right, to the extent the Company deems necessary or advisable, in its sole discretion, to unilaterally amend the Plan and/or this Agreement to ensure that all RSUs are awarded in a manner that qualifies for exemption from or complies with Section 409A, provided, however, that the Company makes no undertaking to preclude Section 409A from applying to this Award of RSUs. Any payments described in this Section 13(g) that are due within the “short term deferral period” as defined in Section 409A shall not be treated as deferred compensation unless applicable law requires otherwise. If and to the extent any portion of any payment, compensation or other benefit provided to the Participant in connection with his or her termination of service is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A and the Participant is a specified employee as defined in Section 409A(2)(B)(i) of the Code, as determined by the Company in accordance with its procedures, by which determination the Participant hereby agrees that he or she is bound, such portion of the payment, compensation or other benefit shall not be paid before the day that is six months plus one day after the date of separation from service (as determined under Section 409A (the “New Payment Date”)), except as Section 409A may then permit. The aggregate of any payments that otherwise would have been paid to the Participant during the period between the date of separation from service and the New Payment Date shall be paid to the Participant in a lump sum on such New Payment Date, and any remaining payments will be paid on their original schedule. Notwithstanding the foregoing, the Company, its subsidiaries, directors, officers and agents shall have no liability to a Participant, or any other party, if an Award that is

intended to be exempt from, or compliant with, Section 409A is not so exempt or compliant, or for any action taken by the Committee.

(h) Governing Law/Choice of Venue. This Agreement shall be governed by and interpreted in accordance with the laws of the State of Delaware, without giving effect to the principles of the conflicts of laws thereof. For purposes of litigating any dispute that arises directly or indirectly from the relationship of the parties, evidenced by this Award or the Agreement, the parties hereby submit to and consent to the exclusive jurisdiction of the State of Vermont and agree that such litigation shall be conducted only in the courts of Rutland County, Vermont, or the federal courts for the United States for the District of Vermont, and no other courts, where this Award is made and/or to be performed.

(i) Administrator Authority. The Committee will have the power to interpret the Plan and this Agreement and to adopt such rules for the administration, interpretation and application of the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any RSUs have been earned). All actions taken and all interpretations and determinations made by the Committee in good faith will be final and binding upon Participant, the Company and all other interested persons.
