CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

(1) BASIS OF PRESENTATION

The accompanying consolidated interim financial statements are unaudited and include the accounts of Clean Harbors, Inc. and its subsidiaries (collectively, “Clean Harbors,” the “Company” or "we") and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) and, in the opinion of management, include all adjustments which are of a normal recurring nature, necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented. Management has made estimates and assumptions affecting the amounts reported in the Company's consolidated interim financial statements and accompanying footnotes, actual results could differ from those estimates and judgments. The results for interim periods are not necessarily indicative of results for the entire year or any other interim periods. The financial statements presented herein should be read in connection with the financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014, which includes the audited consolidated balance sheet as of December 31, 2014 from which the one presented herein was derived.
Reclassifications

During the third quarter of 2014, the Company aggregated the cash flow effects of the change in unbilled receivables with the change from accounts receivable in the Consolidated Statements of Cash Flows. Previously the cash flow effect of the change in unbilled receivables was aggregated with changes in other current assets. Prior year amounts have been recast to conform to the current year presentation.

(2) SIGNIFICANT ACCOUNTING POLICIES
The Company's significant accounting policies are described in Note 2, "Significant Accounting Policies," in the Company's Annual Report on Form 10-K for the year ended December 31, 2014. There have been no material changes in these policies or their application.
Recent Accounting Pronouncements
Standards implemented
In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”)
2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360). The amendments in ASU 2014-08 provide guidance for the recognition and disclosure of discontinued operations. The adoption of ASU 2014-08 did not have an impact on the Company's consolidated financial statements.
Standards to be implemented
In May 2014, FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new guidance is currently effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2017.
In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810). The amendment provides guidance regarding amendments to the consolidation analysis. The amendments in this update are currently effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2015.
The Company is currently evaluating the impact that the above standards to be implemented will have on the Company's consolidated financial statements.
In April 2015, FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30). The amendment provides guidance regarding the simplification of the presentation of debt issuance costs. The amendments in this update are currently effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2015. The impact of this standard on the Company's consolidated financial statements is limited to a reclassification of deferred financing costs from an asset balance to inclusion as an offset against the carrying value of long term obligations.
In July 2015, FASB issued ASU 2015-11, Inventory (Topic 330). The amendment provides guidance regarding the measurement of inventory. Entities should measure inventory within the scope of this update at the lower of cost and net realizable

value. The amendments in this update are currently effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016. Adoption is not expected to have a material impact on the Company's consolidated financial statements.
(3) BUSINESS COMBINATIONS
2015 Acquisition

On April 11, 2015, the Company completed the acquisition of Heckmann Environmental Services, Inc. (“HES”) and Thermo Fluids Inc. (“TFI”), a wholly-owned subsidiary of HES. The acquisition was accomplished through a purchase by Safety-Kleen, Inc., a wholly-owned subsidiary of the Company, of all of the issued and outstanding shares of HES from Nuverra Environmental Solutions, Inc. (“NES”). HES is a holding company that does not conduct any operations. TFI provides environmental services, including used oil recycling, used oil filter recycling, antifreeze products, parts washers and solvent recycling, and industrial waste management services, including vacuum services, remediation, lab pack and hazardous waste management. The Company acquired TFI for an estimated preliminary purchase price of $77.1 million inclusive of current estimates of and subject to certain closing and post-closing adjustments relating to working capital and other assumed liabilities. The acquisition was financed with cash on hand and expands the Company’s environmental services customer base while also complimenting the SK Environmental Services network and presence in the western United States. The amount of revenue from TFI included in the Company's results of operations for the period ended June 30, 2015 was $11.7 million. During the three and six months ended June 30, 2015, the Company incurred acquisition-related costs of approximately $0.3 million and $0.4 million, respectively, in connection with the transaction which are primarily included in selling, general and administrative expenses in the consolidated statements of income. Results of TFI since acquisition have been included within the SK Environmental Services segment.

The allocation of the purchase price was based on preliminary estimates of the fair value of assets acquired and liabilities assumed as of April 11, 2015, as the Company is continuing to obtain information to complete its valuation of these accounts and the associated tax accounting. The components and preliminary allocation of the purchase price consist of the following amounts (in thousands):

The Company assesses goodwill for impairment on an annual basis as of December 31, or at an interim date when events or changes in the business environment would more likely than not reduce the fair value of a reporting unit below its carrying value. The Company conducted the annual impairment test of goodwill for all reporting units as of December 31, 2014 and determined that no adjustment to the carrying value of goodwill for any reporting unit was necessary because the fair value of each of the reporting units exceeded that reporting unit's respective carrying value.

Table of Contents

As disclosed in the Company's annual report on form 10K for the year ended December 31, 2014, the fair value of the Oil and Gas Field Services reporting unit did not significantly exceed its carrying amount. During the first quarter of 2015, the Company evaluated the reporting unit’s performance along with other business specific, and macroeconomic industry factors and concluded that no interim impairment test was necessary.

During the quarter ended June 30, 2015, certain events and changes in circumstances arose which led management of the Company to conclude that the fair value of the Oil and Gas Field Services reporting unit may be less than its carrying value and therefore an interim impairment test was conducted relative to goodwill recorded by the Oil and Gas Field Services reporting unit. The primary events and changes in circumstances which led to this conclusion were:    

The second quarter is the period of time where greater levels of communication with customers and the receipt of bids and proposals for project work takes place and provide management with more clarity into levels of activity and other economic and business indicators for the latter half of the fiscal year and into the first quarter of the following year. During the quarter ended June 30, 2015 it became apparent that oil and gas exploration and production activity would continue to be lower than historical periods and lower than previously anticipated by the Company. This was evidenced by reduced volume in bid and proposal requests from customers and communications indicating the reduction in customer budgets in these areas as well as lower than anticipated pricing for our services.

Market and industry reports which management looks to in projecting business conditions and establishing forecast information evidenced more pessimistic views in the near term. The continued depressed price of oil without any upward momentum since December 2014 as well as declining and expected continued decline in rig count for the remainder of 2015 have resulted in lower estimates of industry activity in the second half of 2015 and early 2016.

In recognition of lower than anticipated business results and less optimistic market indicators, management significantly lowered its 2015 forecasts relative to the Oil and Gas reporting unit.

In performing Step I of this interim goodwill impairment test, the estimated fair value of the Oil and Gas Field Services reporting unit was determined using an income approach based upon discounted cash flows and was compared to the reporting unit's carrying value as of June 30, 2015. Based on the results of that valuation, the carrying amount of the reporting unit, including $32.0 million of goodwill, exceeded its estimated fair value and as a result the Company performed Step II of the goodwill impairment test to determine the amount of goodwill impairment charge to be recorded.

Step II of the goodwill impairment test required the Company to perform a theoretical purchase price allocation for the reporting unit to determine the implied fair value of goodwill and to compare the implied fair value of goodwill to the recorded amount. The estimates of the fair values of intangible assets identified in performing this theoretical purchase price allocation and resulting implied fair value of goodwill required significant judgment. Based on the results of this goodwill impairment test the implied value of goodwill was $0 and as such the Company recognized a goodwill impairment charge equal to the recorded amount of goodwill or $32.0 million as of June 30, 2015.

The factors contributing to the $32.0 million goodwill impairment charge principally related to events and changes in circumstances discussed above which had negative impacts on the Company’s prospective financial information utilized in its discounted cash flow model prepared in connection with the interim impairment test. The currently projected lower levels of activity and pricing in the latter half of the year which became evident during the second quarter decreased the reporting unit’s anticipated future cash flows for 2015 as compared to those estimated previously. These factors have also provided evidence of a longer than expected overall recovery from current industry lows which negatively impacted the estimated levels of cash flows in future periods that are assumed in the cash flow models utilized in the interim impairment test. These factors adversely affected the estimated fair value of the reporting unit as of June 30, 2015 and ultimately led to the recognition of the goodwill impairment charge.

Significant judgments and unobservable inputs categorized as Level III in the fair value hierarchy are inherent in the impairment tests performed and include assumptions about the amount and timing of expected future cash flows, growth rates, and the determination of appropriate discount rates. The Company believes that the assumptions used in its annual and any interim date impairment tests are reasonable, but variations in any of the assumptions may result in different calculations of fair values and impairment charges.

The Company also performed an analysis to consider whether the reporting unit's carrying values of finite-lived intangible and other long lived assets may not be entirely recoverable. As of June 30, 2015 the Oil and Gas Field Services reporting unit had property, plant and equipment, net of $185.3 million, other intangible assets of $20.1 million consisting of: permits of $0.1 million, customer and supplier relationships of $10.7 million and other intangible assets of $9.3 million. Based on this analysis, sufficient undiscounted cash flows were available over those assets' remaining lives to demonstrate recoverability and thus no impairment exists.

was $595.0 million and based on quoted market prices for the instrument. The fair value of the 2021 Notes is considered a Level 2 measure according to the fair value hierarchy.
The Company also maintains a revolving credit facility which as of June 30, 2015 and December 31, 2014 had no outstanding loan balances. At June 30, 2015, $242.8 million was available to borrow and outstanding letters of credit were $144.9 million. At December 31, 2014, $238.4 million was available to borrow and outstanding letters of credit were $134.5 million.
Available credit for Clean Harbors, Inc. ("Parent") and its domestic subsidiaries is subject to 85% of their eligible accounts receivable and 100% of their cash deposited in a controlled account with the agent. The revolving credit facility is guaranteed by all of Parent’s domestic subsidiaries and secured by substantially all of Parent’s and its domestic subsidiaries’ assets. Available credit for Parent’s Canadian subsidiaries is subject to 85% of their eligible accounts receivable and 100% of their cash deposited in a controlled account with the agent’s Canadian affiliate. The obligations of the Canadian subsidiaries under the revolving credit facility are guaranteed by all of Parent’s Canadian subsidiaries and secured by the accounts receivable of the Canadian subsidiaries, but the Canadian subsidiaries do not guarantee and are not otherwise responsible for the obligations of Parent or its domestic subsidiaries.

(11) INCOME TAXES 
The Company did not record any tax charges or benefits as a result of the goodwill impairment charge recorded in the second quarter. Effective tax rates for the three and six months ended June 30, 2015 were 74.6% and 88.6%. Absent the impact of the impairment charge on pre-tax income from operations, the Company’s effective tax rate for the three and six months ended June 30, 2015 was 41.8% and 42.2%, respectively, compared to 39.1% and 38.9% for the same periods in 2014. The increase in the effective rates for the three and six months ended June 30, 2015 was primarily due to the increased taxable earnings in the United States versus taxable losses recorded in Canada.
As of June 30, 2015 and December 31, 2014, the Company had recorded $2.6 million and $2.5 million, respectively, of liabilities for unrecognized tax benefits and $0.4 million of interest, respectively.
Due to expiring statute of limitation periods, the Company believes that total unrecognized tax benefits will decrease by approximately $0.6 million within the next 12 months. This is the result of an audit settlement for one of our foreign entities.

Performance Stock Awards

The following information relates to performance stock awards that have been granted to employees under the Company's Plans. Performance stock awards are subject to performance criteria established by the compensation committee of the Company's board of directors prior to or at the date of grant. The vesting of the performance stock awards is based on achieving such targets typically based on revenue, Adjusted EBITDA margin, ROIC percentage and Total Recordable Incident Rate. In addition performance stock awards include continued service conditions. The fair value of each performance stock award is based on the closing price of the Company's common stock on the date of grant and is amortized to expense over the service period if achievement of performance measures is considered probable.

(15) COMMITMENTS AND CONTINGENCIES
Legal and Administrative Proceedings
The Company and its subsidiaries are subject to legal proceedings and claims arising in the ordinary course of business. Actions filed against the Company arise from commercial and employment-related claims including alleged class actions related to sales practices and wage and hour claims. The plaintiffs in these actions may be seeking damages or injunctive relief or both. These actions are in various jurisdictions and stages of proceedings, and some are covered in part by insurance. In addition, the Company’s waste management services operations are regulated by federal, state, provincial and local laws enacted to regulate discharge of materials into the environment, remediation of contaminated soil and groundwater or otherwise protect the environment. This ongoing regulation results in the Company frequently becoming a party to legal or administrative proceedings involving all levels of governmental authorities and other interested parties. The issues involved in such proceedings generally relate to alleged violations of existing permits and licenses or alleged responsibility under federal or state Superfund laws to remediate contamination at properties owned either by the Company or by other parties (“third party sites”) to which either the Company or the prior owners of certain of the Company’s facilities shipped wastes.
At June 30, 2015 and December 31, 2014, the Company had recorded reserves of $30.6 million and $33.6 million, respectively, in the Company's financial statements for actual or probable liabilities related to the legal and administrative proceedings in which the Company was then involved, the principal of which are described below. At June 30, 2015 and December 31, 2014, the Company also believed that it was reasonably possible that the amount of these potential liabilities could be as much as $2.5 million and $2.9 million more, respectively. The Company periodically adjusts the aggregate amount of these reserves when actual or probable liabilities are paid or otherwise discharged, new claims arise, or additional relevant information about existing or probable claims becomes available. As of June 30, 2015 and December 31, 2014, the $30.6 million and $33.6

million, respectively, of reserves consisted of (i) $24.4 million and $27.7 million related to pending legal or administrative proceedings, including Superfund liabilities, which were included in remedial liabilities on the consolidated balance sheets, and (ii) $6.2 million and $5.9 million, respectively, primarily related to federal, state and provincial enforcement actions, which were included in accrued expenses on the consolidated balance sheets.
As of June 30, 2015, the principal legal and administrative proceedings in which the Company was involved, or which had been terminated during 2015, were as follows:
Ville Mercier.    In September 2002, the Company acquired the stock of a subsidiary (the "Mercier Subsidiary") which owns a hazardous waste incinerator in Ville Mercier, Quebec (the "Mercier Facility"). The property adjacent to the Mercier Facility, which is also owned by the Mercier Subsidiary, is now contaminated as a result of actions dating back to 1968, when the Government of Quebec issued to a company unrelated to the Mercier Subsidiary two permits to dump organic liquids into lagoons on the property. In 1999, Ville Mercier and three neighboring municipalities filed separate legal proceedings against the Mercier Subsidiary and the Government of Quebec. In 2012, the municipalities amended their existing statement of claim to seek $2.9 million (Cdn) in general damages and $10.0 million (Cdn) in punitive damages, plus interest and costs, as well as injunctive relief. Both the Government of Quebec and the Company have filed summary judgment motions against the municipalities. The parties are currently attempting to negotiate a resolution and hearings on the motions have been delayed. In September 2007, the Quebec Minister of Sustainable Development, Environment and Parks issued a Notice pursuant to Section 115.1 of the Environment Quality Act, superseding Notices issued in 1992, which are the subject of the pending litigation. The more recent Notice notifies the Mercier Subsidiary that, if the Mercier Subsidiary does not take certain remedial measures at the site, the Minister intends to undertake those measures at the site and claim direct and indirect costs related to such measures.
The Mercier Subsidiary continues to assert that it has no responsibility for the groundwater contamination in the region and will contest any action by the Ministry to impose costs for remedial measures on the Mercier Subsidiary. The Company also continues to pursue settlement options. At June 30, 2015 and December 31, 2014, the Company had accrued $11.9 million and $12.7 million, respectively, for remedial liabilities relating to the Ville Mercier legal proceedings. The decrease was due to a weakening of the Canadian dollar.
Refinery Incident. In September 2014, a customer filed suit against the Company and two other contractors and their respective insurers seeking to be named as an additional insured on the Company’s and the other contractors’ liability policies for an April 2013 industrial fire that occurred at the customer’s refining facility. The Company and its insurers have resolved the dispute relating to the customer’s additional insured status and the customer has agreed to indemnify the Company from any additional losses relating to the matter.  The Company does not believe that this matter will have a material effect on its financial position or the results of operations.
Safety-Kleen Legal Proceedings. On December 28, 2012, the Company acquired Safety-Kleen, Inc. and thereby became subject to the legal proceedings in which Safety-Kleen and its subsidiaries (collectively "Safety-Kleen") were a party on that date. In addition to certain Superfund proceedings in which Safety-Kleen has been named as a potentially responsible party as described below under “Superfund Proceedings,” the principal such legal proceedings involving Safety-Kleen which were outstanding as of June 30, 2015 were as follows:
Product Liability Cases. Safety-Kleen is named as a defendant in various lawsuits that are currently pending in various courts and jurisdictions throughout the United States, including approximately 52 proceedings (excluding cases which have been settled but not formally dismissed) as of June 30, 2015, wherein persons claim personal injury resulting from the use of Safety-Kleen's parts cleaning equipment or cleaning products. These proceedings typically involve allegations that the solvent used in Safety-Kleen's parts cleaning equipment contains contaminants and/or that Safety-Kleen's recycling process does not effectively remove the contaminants that become entrained in the solvent during their use. In addition, certain claimants assert that Safety-Kleen failed to warn adequately the product user of potential risks, including an historic failure to warn that solvent contains trace amounts of toxic or hazardous substances such as benzene. Safety-Kleen maintains insurance that it believes will provide coverage for these claims (over amounts accrued for self-insured retentions and deductibles in certain limited cases), except for punitive damages to the extent not insurable under state law or excluded from insurance coverage. Safety-Kleen believes that these claims lack merit and has historically vigorously defended, and intends to continue to vigorously defend, itself and the safety of its products against all of these claims. Such matters are subject to many uncertainties and outcomes are not predictable with assurance. Consequently, Safety-Kleen is unable to ascertain the ultimate aggregate amount of monetary liability or financial impact with respect to these matters as of June 30, 2015. From January 1, 2015 to June 30, 2015, 24 product liability claims were settled or dismissed. Due to the nature of these claims and the related insurance, the Company did not incur any expense as Safety-Kleen's insurance provided coverage in full for all such claims. Safety-Kleen may be named in similar, additional lawsuits in the future, including claims for which insurance coverage may not be available.

Fee Class Action Claims. In October 2010, two customers filed a complaint, individually and on behalf of all similarly situated customers in the State of Alabama, alleging that Safety-Kleen improperly assessed fuel surcharges and extended area service fees. In 2012, similar lawsuits were filed by the same law firm in California and Missouri. On January 15, 2015, the Company reached a tentative settlement of the pending class action lawsuits, which were broadened to include similar claims on behalf of customers in Florida, West Virginia and Arkansas. The final settlement was approved by the court in a fairness hearing in June 2015. The exact settlement cost is not yet determinable, but it is not expected to be material.
Superfund Proceedings
The Company has been notified that either the Company (which, since December 28, 2012, includes Safety-Kleen) or the prior owners of certain of the Company's facilities for which the Company may have certain indemnification obligations have been identified as potentially responsible parties ("PRPs") or potential PRPs in connection with 128 sites which are subject to or are proposed to become subject to proceedings under federal or state Superfund laws. Of the 128 sites, two (the Wichita Facility and the BR Facility described below) involve facilities that are now owned by the Company and 126 involve third party sites to which either the Company or the prior owners of certain of the Company’s facilities shipped wastes. Of the 126 third party sites, 29 are now settled, 22 are currently requiring expenditures on remediation and 75 are not currently requiring expenditures on remediation.
In connection with each site, the Company has estimated the extent, if any, to which it may be subject, either directly or as a result of any indemnification obligations, for cleanup and remediation costs, related legal and consulting costs associated with PRP investigations, settlements, and related legal and administrative proceedings. The amount of such actual and potential liability is inherently difficult to estimate because of, among other relevant factors, uncertainties as to the legal liability (if any) of the Company or the prior owners of certain of the Company's facilities to contribute a portion of the cleanup costs, the assumptions that must be made in calculating the estimated cost and timing of remediation, the identification of other PRPs and their respective capability and obligation to contribute to remediation efforts, and the existence and legal standing of indemnification agreements (if any) with prior owners, which may either benefit the Company or subject the Company to potential indemnification obligations. In addition to the Wichita Property and the BR Facility, Clean Harbors believes its potential liability could exceed $100,000 at 11 of the 126 third party sites.
Wichita Property.    The Company acquired in 2002 a service center located in Wichita, Kansas (the "Wichita Property"). The Wichita Property is one of several properties located within the boundaries of a 1,400 acre state-designated Superfund site in an old industrial section of Wichita known as the North Industrial Corridor Site. Along with numerous other PRPs, the former owner executed a consent decree relating to such site with the U.S. Environmental Protection Agency (the "EPA"), and the Company is continuing an ongoing remediation program for the Wichita Property in accordance with that consent decree. The Company also acquired rights under an indemnification agreement between the former owner and an earlier owner of the Wichita Property. The Company filed suit against the earlier owner in July of 2015 to recoup costs incurred during the cleanup of the property.
BR Facility.    The Company acquired in 2002 a former hazardous waste incinerator and landfill in Baton Rouge (the "BR Facility"), for which operations had been previously discontinued by the prior owner. In September 2007, the EPA issued a special notice letter to the Company related to the Devil's Swamp Lake Site ("Devil's Swamp") in East Baton Rouge Parish, Louisiana. Devil's Swamp includes a lake located downstream of an outfall ditch where wastewater and stormwater have been discharged, and Devil's Swamp is proposed to be included on the National Priorities List due to the presence of Contaminants of Concern ("COC") cited by the EPA. These COCs include substances of the kind found in wastewater and storm water discharged from the BR Facility in past operations. The EPA originally requested COC generators to submit a good faith offer to conduct a remedial investigation feasibility study directed towards the eventual remediation of the site. The Company is currently performing corrective actions at the BR Facility under an order issued by the Louisiana Department of Environmental Quality, and has begun conducting the remedial investigation and feasibility study under an order issued by the EPA. The Company cannot presently estimate the potential additional liability for the Devil's Swamp cleanup until a final remedy is selected by the EPA.
Third Party Sites.    Of the 126 third party sites at which the Company has been notified it is a PRP or potential PRP or may have indemnification obligations, Clean Harbors has an indemnification agreement at 11 of these sites with ChemWaste, a former subsidiary of Waste Management, Inc., and at six additional of these third party sites, Safety-Kleen has a similar indemnification agreement with McKesson Corporation. These agreements indemnify the Company (which now includes Safety-Kleen) with respect to any liability at the 17 sites for waste disposed prior to the Company's (or Safety-Kleen's) acquisition of the former subsidiaries of Waste Management or McKesson which had shipped wastes to those sites. Accordingly, Waste Management or McKesson are paying all costs of defending those subsidiaries in those 17 cases, including legal fees and settlement costs. However, there can be no guarantee that the Company's ultimate liabilities for those sites will not exceed the amount recorded or that indemnities applicable to any of these sites will be available to pay all or a portion of related costs. Except for the indemnification agreements which the Company holds from ChemWaste and McKesson, the Company does not have an indemnity agreement with respect to any of the 126 third party sites discussed above.

Federal, State and Provincial Enforcement Actions
From time to time, the Company pays fines or penalties in regulatory proceedings relating primarily to waste treatment, storage or disposal facilities. As of June 30, 2015 and December 31, 2014, there were four proceedings for which the Company reasonably believed that the sanctions could equal or exceed $100,000. The Company believes that the fines or other penalties in these or any of the other regulatory proceedings will, individually or in the aggregate, not have a material effect on its financial condition, results of operations or cash flows.
(16) SEGMENT REPORTING 
Segment reporting is prepared on the same basis that the Company's chief executive officer, who is the Company's chief operating decision maker, manages the business, makes operating decisions and assesses performance.

Third party revenue is revenue billed to outside customers by a particular segment. Direct revenue is revenue allocated to the segment performing the provided service. Intersegment revenues represent the sharing of third party revenues among the segments based on products and services provided by each segment as if the products and services were sold directly to the third party. The intersegment revenues are shown net. The negative intersegment revenues are due to more transfers out of customer revenues to other segments than transfers in of customer revenues from other segments. The operations not managed through the Company’s six reportable segments are recorded as “Corporate Items.” Corporate Items revenues consist of two different operations for which the revenues are insignificant. Corporate Items cost of revenues represents certain central services that are not allocated to the six segments for internal reporting purposes. Corporate Items selling, general and administrative expenses include typical corporate items such as legal, accounting and other items of a general corporate nature that are not allocated to the Company’s six reportable segments. Performance of the segments is evaluated on several factors, of which the primary financial measure is “Adjusted EBITDA,” which consists of net income plus accretion of environmental liabilities, depreciation and amortization, net interest expense, provision for income taxes, other non-cash charges not deemed representative of fundamental segment results and excludes other (expense) income. Transactions between the segments are accounted for at the Company’s best estimate based on similar transactions with outside customers.

(17) GUARANTOR AND NON-GUARANTOR SUBSIDIARIES FINANCIAL INFORMATION
The 2020 Notes and 2021 Notes are guaranteed by substantially all of the Company's subsidiaries organized in the United States. Each guarantor for the 2020 Notes and 2021 Notes is a 100% owned subsidiary of the Company and its guarantee is both full and unconditional and joint and several.  The 2020 Notes and 2021 Notes are not guaranteed by the Company’s Canadian or other foreign subsidiaries. The following presents supplemental condensed consolidating financial information for the parent company, the guarantor subsidiaries and the non-guarantor subsidiaries, respectively.
Revision of Previously Reported Condensed Consolidating Information - As discussed further in the Company's 2014 Annual Report on Form 10-K, during preparation of the December 31, 2014 financial statements, management determined that certain amounts in the Company’s condensed consolidating financial information as previously presented in this Guarantor And Non-Guarantor Subsidiaries footnote for the period ended June 30, 2014 was not presented in accordance with the requirements of Rule 3-10 of SEC Regulation S-X (“Rule 3-10”). The accompanying financial information related to the period ended June 30, 2014 has therefore been revised to correct the historical presentation. The revisions primarily relate to the following items:
(Benefit) provision for income taxes - Excess provision for income taxes was allocated to Clean Harbors, Inc. and under allocated to U.S. Guarantor Subsidiaries.

Equity in earnings of subsidiaries, net of tax - interest expense resulting from transactions between the U.S. Guarantor Subsidiaries and Foreign Non-Guarantor Subsidiaries was incorrectly excluded in the application of the equity method of accounting required by Rule 3-10 resulting in an overstatement of equity in earnings of subsidiaries, net of tax, as reflected in the financial information for the U.S. Guarantor Subsidiaries.

These revisions impacted the condensed consolidating information for the period ended June 30, 2014 as presented in this footnote only and did not affect any of the Company's consolidated financial statements or ratios based thereon. There was no impact to the Company's loan covenants as a result of these corrections.
