NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

~~June 17, 2017~~March 24, 2018

(1) ORGANIZATION AND NATURE OF OPERATIONS

Heritage-Crystal Clean, Inc., a Delaware corporation and its subsidiaries (collectively the “Company”), ~~provide~~provides parts cleaning, hazardous and non-hazardous containerized waste, used oil collection, vacuum, antifreeze recycling and field services primarily to small and mid-sized industrial and vehicle maintenance customers. The Company owns and operates a used oil re-refinery where it re-refines used oils and sells high quality base oil for lubricants as well as other re-refinery products. The Company also has multiple locations where it dehydrates used oil. The oil processed at these locations is sold as recycled fuel oil. The ~~company~~Company also operates multiple wastewater treatment plants and antifreeze recycling facilities at which it produces virgin-quality antifreeze. The ~~Company's locations are~~Company operates in the United States and Ontario, Canada. The Company conducts its primary business operations through Heritage-Crystal Clean, LLC, its wholly owned subsidiary, and all intercompany balances have been eliminated in consolidation.

The Company has two reportable segments: "Environmental Services" and "Oil Business." The Environmental Services segment consists of the Company's parts cleaning, containerized waste management, vacuum truck services, antifreeze recycling activities, and field services. The Oil Business segment consists of the Company's used oil collection, recycled fuel oil sales, used oil re-refining activities, and used oil filter removal and disposal services. No customer represented greater than 10% of consolidated revenues for any of the periods presented. There were no intersegment revenues. Both segments operate in the United States, and the Environmental Services segment also operates, to an immaterial degree, in Ontario, Canada.

The Company’s fiscal year ends on the Saturday closest to December 31. The most recent fiscal year ended on December ~~31, 2016~~30, 2017. Each of the Company's first three fiscal quarters consists of twelve weeks while the last fiscal quarter consists of sixteen or seventeen weeks.

In the Company's Environmental Services segment, product revenues include sales of solvent, machines, absorbent, accessories, and antifreeze; service revenues include servicing of parts cleaning machines, drum waste removal services, vacuum truck services, field services, and other services. In the Company's Oil Business segment, product revenues include sales of re-refined base oil, recycled fuel oil, used oil, and other products; service revenues include revenues from used oil collection activities, collecting and disposing of waste water and removal and disposal of used oil filters. Due to the Company's integrated business model, it is impracticable to separately present costs of tangible products and costs of services.

2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company's significant accounting policies are described in Note 2, "Summary of Significant Accounting Policies," in the Company's Annual Report on Form 10-K for the fiscal year ended December ~~31, 2016.~~30, 2017. There have been no material changes in these policies or their ~~application.~~application with the exception of revenue recognition. See footnote 3 - Revenue for more information.

Recently Issued Accounting Pronouncements
Standard	Issuance Date	Description	Our Effective Date	Effect on the Financial Statements
ASU 2016-02 Leases (Topic 842)	February 2016	This update was issued to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Early application of the amendments in this update is permitted for all entities.	January 4, 2019	The Company is currently evaluating the effect that implementation of this update will have on its consolidated financial position and results of operations. The Company anticipates that implementation of this standard will result in an increase to assets and an increase to liabilities. To date, certain personnel have attended technical training concerning this new lease accounting standard.



Recently Issued Accounting Standards Adopted
Standard	Issuance Date	Description	Effective Date	Effect on the Financial Statements
ASU 2014-09 “Revenue from Contracts with Customers (Topic 606),” ASU 2014-15 “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” ASU 2016-08 “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” ASU 2016-10 “ Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing,” and ASU 2016-12 “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients”	May 2014 and subsequent	These standards outline a single comprehensive model for entities to use in accounting for revenue using a five-step process that supersedes virtually all existing revenue guidance. The underlying principle 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. Entities have the option of using either a full retrospective approach or a modified retrospective approach to adopt the guidance. Early adoption is permitted.	December 31, 2017	~~The Company is continuing to evaluate~~On December 31, 2017, we adopted the ~~effect that this~~new accounting standard will have on our consolidated financial position and results of operations. To date, certain personnel have attended technical training concerning this new revenue recognition standard. The Company is working to identify each ofASC 606, “Revenue from Contracts with Customers” using the different types of contracts with customers and the various performance obligations associated with each type of contract. The Company is also assessing the changes that will be necessary to our information systems to enable us to capture the information necessary to recognize revenue in accordance with the new standard and comply with the additional disclosure requirements. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (the fullmodified retrospective ~~approach), or retrospectively with~~method. We recognized the cumulative effect as an adjustment to our opening balance of initially applying the guidance recognized at the date of initial application (the modified retrospective approach). The Company will adopt the standard in the first quarter of fiscal 2018 and currently anticipates applying the modified retrospective approach.

Effective December 31, 2017, we adopted the requirements of Topic 606. The cumulative effects of the changes made to our statement of income and balance sheet were as follows:



~~Recently issued accounting standards adopted~~
~~Standard~~	~~Issuance Date~~	~~Description~~	~~Effective Date~~	~~Effect on the Financial Statements~~
~~ASU 2016-09 Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting.~~ ~~(Topic 718)~~	~~March 2016~~	This update addresses the simplification of accounting for employee share-based payment transactions as it pertains to income taxes, the classification of awards as equity or liabilities, accounting for forfeitures, statutory tax withholding requirements, and certain classifications on the statement of cash flows. Early adoption is permitted.	~~January 1, 2017~~	ASU 2016-09 simplified the treatment for employee share-based compensation by allowing an entity to recognize excess tax benefits in the current period whether or not current taxes payable are reduced. Prior to 2017 the Company could not recognize windfall tax benefits associated with employee share-based compensation because it was in an NOL position and current taxes payable would not be reduced by the excess tax benefits. As a result of ASU 2016-09 the Company recognized excess tax benefits of $2.5 million from share-based compensation from prior years, resulting in cumulative-effect increases to retained earnings and deferred tax assets of approximately $1.0 million.
~~ASU 2015-11, Simplifying the Measurement of Inventory. (Topic 330)~~	~~July 2015~~	This update requires the measurement of inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.	~~January 1, 2017~~	~~The adoption of ASU 2015-11 at the start of fiscal 2017 resulted in no impact to our consolidated financial statements.~~

~~(3) BUSINESS COMBINATIONS~~3) REVENUE

~~On December 2, 2016,~~We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue is recognized when our performance obligations under the terms of a contract with our customers are satisfied. Recognition occurs when the Company ~~purchased~~transfers control by completing the ~~assets~~specified services at the point in time the customer benefits from the services performed or once our products are delivered. Revenue is measured as the amount of ~~Recycle Engine Coolant, Inc. ("REC"). The purchase~~consideration we expect to receive in exchange for completing our performance obligations. Sales tax and other taxes we collect with revenue-producing activities are excluded from revenue. In the case of contracts with multiple performance obligations, the Company allocates the transaction price ~~for~~to each performance obligation based on the ~~acquisition was $0.7 million, including $0.1 million placed into escrow.~~relative stand-alone selling prices of the various goods and/or services encompassed by the contract. We do not have any material significant payment terms as payment is generally due within 30 days after the performance obligation has been satisfactorily completed. The Company ~~purchased~~has elected the ~~assets~~practical expedient to recognize the incremental costs of ~~REC~~obtaining a contract as an expense when incurred if the amortization period of the asset that we otherwise would have recognized is one year or less. In applying the guidance in ~~order to expand its antifreeze recycling capabilities.~~Topic 606, there were no judgments or estimates made that the Company deems significant.

~~On March 24, 2016,~~Accounts Receivable — Net, includes amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. The allowance for doubtful accounts is the Company's best estimate of the amount of probable credit losses in the Company's existing accounts receivable.

(7) GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill is measured as a residual amount as of the acquisition date, which in most cases results in measuring goodwill as an excess of the purchase consideration transferred plus the fair value of any noncontrolling interest in the acquiree over the fair value of the net assets acquired, including any contingent consideration. The Company tests goodwill for impairment annually in the fourth quarter and in interim periods if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company's determination of fair value requires certain assumptions and estimates, such as margin expectations, market conditions, growth expectations, expected changes in working capital, etc., regarding expected future profitability and expected future cash flows. The Company tests goodwill for impairment at each of its two reporting units, Environmental Services and Oil ~~Business, and the Company does not aggregate reporting units for purposes of impairment testing.~~Business.

~~(8)~~(9) DEBT AND FINANCING ARRANGEMENTS

Bank Credit Facility

~~On February 21, 2017, the Company entered into a new~~The Company's Credit Agreement as amended ("Credit Agreement") ~~replacing the prior Credit Agreement ("Prior Credit Agreement") dated as of June 29, 2015. The Credit Agreement~~, provides for borrowings of up to $95.0 million, subject to the satisfaction of certain terms and conditions, comprised of a term loan of $30.0 million and up to $65.0 million of borrowings under the revolving loan portion. The actual amount of borrowings available under the revolving loan portion of the Credit Agreement is limited by the Company's total leverage ratio. The amount available to draw at any point in time would be further reduced by any standby letters of credit issued.

Loans made under the ~~New~~ Credit Agreement may be Base Rate Loans or LIBOR Rate Loans, at the election of the Company subject to certain exceptions. Base Rate Loans have an interest rate equal to (i) the higher of (a) the federal funds rate plus 0.5%, (b) the London Interbank Offering Rate (“LIBOR”) plus 1%, or (c) Bank of America's prime rate, plus (ii) a variable margin of between 0.75% and 1.75% depending on the Company's total leverage ratio, calculated on a consolidated basis. LIBOR rate loans have an interest rate equal to (i) the LIBOR rate plus (ii) a variable margin of between 1.75% and 2.75% depending on the Company's total leverage ratio. Amounts borrowed under the ~~New~~ Credit Agreement are secured by a security interest in substantially all of the Company's tangible and intangible assets. ~~In June 2017, the Company entered into a First Amendment to the Credit Agreement that expands the Company's ability to make dispositions without bank group approval.~~

~~As of the Effective date of February 21, 2017, the effective interest rate on the term loan was 3.28% and the effective rate on the revolving loan was 3.28%.~~

The Credit Agreement contains customary terms and provisions (including representations, covenants, and conditions) for transactions of this type. Certain covenants, among other things, restrict the Company's and its subsidiaries' ability to incur indebtedness, grant liens, make investments and sell assets. The Credit Agreement also contains customary events of default, covenants and representations and warranties. Financial covenants include:

An interest coverage ratio (based on interest expense and EBITDA) of at least 3.5 to 1.0;

A total leverage ratio no greater than 3.0 to 1.0, provided that in the event of a permitted acquisition having an aggregate consideration equal to $10.0 million or more, at the Borrower’s election, the foregoing 3.00 to 1.00 shall be deemed to be 3.25 to 1.00 for the fiscal quarter in which such permitted acquisition occurs and the three immediately following fiscal quarters and will thereafter revert to 3.00 to 1.00; and

A capital expenditures covenant limiting capital expenditures to $100.0 million plus, if the capital expenditures permitted have been fully utilized, an additional amount for the remaining term of the Credit Agreement equal to 35% of EBITDA for the thirteen “four-week” periods most recently ended immediately prior to the full utilization of such $100.0 million ~~basket~~basket.

The Credit Agreement places certain limitations on acquisitions and the payment of dividends.

During the first ~~half~~quarter of fiscal 2017, the Company paid and capitalized $1.1 million of debt issuance costs pertaining to the ~~New~~ Credit Agreement and charged $0.2 million of unamortized debt issuance costs pertaining to the ~~Prior~~ Credit Agreement to selling, general, and administrative expenses.

Debt at ~~June 17, 2017~~March 24, 2018 and December ~~31, 2016~~30, 2017 consisted of the following:

During the ~~second~~first quarter of fiscal ~~2017~~2018, the Company recorded interest of ~~$0.4~~$0.3 million on the term loan. During the first ~~half~~quarter of fiscal 2017, ~~the Company recorded interest of $0.9 million on the term loan.~~

~~During the second quarter of fiscal 2016,~~ the Company recorded interest of $0.5 million on the ~~Prior Credit Agreement~~ term ~~loans and capitalized less than~~loan.

Assets for the corporate unallocated amounts consist of property, plant, and equipment used at the corporate headquarters as well as cash and net deferred tax assets.

~~(10)~~(11) COMMITMENTS AND CONTINGENCIES

The Company may enter into purchase obligations with certain vendors. They represent expected payments to third party service providers and other commitments entered into during the normal course of our business. These purchase obligations are generally cancelable with or without notice, without penalty, although certain vendor agreements provide for cancellation fees or penalties depending on the terms of the contract.

The Company has purchase obligations in the form of open purchase orders of ~~$16.7~~$16.3 million as of ~~June 17, 2017~~March 24, 2018, and ~~$9.7~~$15.6 million as of December ~~31, 2016,~~30, 2017, primarily for used oil, solvent, machine purchases, disposal and transportation expenses, and capital expenditures.

The Company may be subject to investigations, claims or lawsuits as a result of operating its business, including matters governed by environmental laws and regulations. The Company may also be subject to tax audits in a variety of jurisdictions. When claims are asserted, the Company evaluates the likelihood that a loss will occur and records a liability for those instances when the likelihood is deemed probable and the exposure is reasonably estimable. The Company carries insurance at levels it believes are adequate to cover loss contingencies based on historical claims activity. When the potential loss exposure is limited to the insurance deductible and the likelihood of loss is determined to be probable, the Company accrues for the amount of the required deductible, unless a lower amount of exposure is estimated. As of ~~June 17, 2017~~March 24, 2018 and December ~~31, 2016~~30, 2017, the Company had accrued ~~$5.6~~$4.0 million and ~~$5.5~~$4.5 million related to loss contingencies and other contingent liabilities, respectively.

~~(11)~~(12) INCOME TAXES

On December 22, 2017, the Tax Cuts and Jobs Act (the "Act") was enacted into law and introduced significant changes to U.S. tax law. The Act reduces the U.S. federal corporate tax rate from 35% to 21%. The new legislation also sets forth a variety of other changes, including a limitation on the tax deductibility of interest expense, the acceleration of business asset expensing, a limitation on the use of net operating losses generated in future years, the repeal of the alternative minimum tax (AMT), and a reduction in the amount of executive pay that could qualify as a tax deduction.

Due to the timing and the complexity involved in applying the provisions of the Act, the Company did not record provisional amounts in our financial statements as of December 30, 2017 related to the one time deemed repatriation of foreign earnings. As the Company collects and prepares necessary data, and interprets the Act and any additional guidance issued by the U.S. Treasury Department, the Internal Revenue Service (IRS), and other standard-setting bodies, the Company will record the provisional amounts related to the one time deemed repatriation of its Canadian subsidiary’s accumulated foreign earnings. The accounting for the tax effects of the deemed repatriation of foreign earnings will be completed later in 2018. The Company estimates that the income related to the deemed repatriation will be offset by U.S. net operating losses.

The Company deducted for federal income tax purposes accelerated "bonus" depreciation on the majority of its capital expenditures for assets placed in service in fiscal 2011 through fiscal ~~2015.~~2017. Therefore, the Company recorded a ~~noncurrent~~ deferred tax liability related to ~~reflect~~the difference between the book basis and the tax basis of those assets. In addition, as a result of the federal bonus depreciation, the Company recorded a Net Operating Loss ("NOL") of ~~$44.7~~$44.7 million, ~~in fiscal 2011,~~ which will begin to expire in 2031. The unexpired balance of the NOL generated in 2011 is $13.7 million as of ~~June 17, 2017~~March 24, 2018. The Company recorded additional NOL during 2012 - 2015 of $13.0 million. The balance on the federal NOL’s generated from 2011 through 2015 at March 24, 2018 was ~~$32.9~~$26.7 million, and the remaining deferred tax asset related to the ~~Company’s~~Company's state and federal NOL was a tax effected balance of ~~$12.5~~$6.3 million.

ASU 2016-09 simplified the treatment for employee share-based compensation by allowing an entity to recognize excess tax benefits in the current period whether or not current taxes payable are reduced. Prior to 2017 the Company could not recognize windfall tax benefits associated with employee share-based compensation because it was in an NOL position and current taxes payable would not be reduced by the excess tax benefits. As a result of ASU 2016-09 the Company recognized excess tax benefits of $2.5 million from share-based compensation from prior years, resulting in cumulative-effect increases to retained earnings and deferred tax assets of approximately $1.0 million.

The Company's effective tax rate for the ~~second~~first quarter of fiscal ~~2017~~2018 was ~~36.3%~~81.1% compared to 36.7% in the ~~second~~first quarter of fiscal ~~2016~~2017. The ~~Company’s effective~~ rate ~~for the first half of fiscal 2017 was 36.5% compared to 65.0% in the first half of fiscal 2016. The rate decrease~~difference is ~~primarily attributed~~principally attributable to the ~~previous year’s first half effect~~differing treatment for financial reporting and income tax reporting of certain state income taxes which are computed on a tax base that reflects substantial modifications to federal taxable income, and that had created comparatively high tax expense due to relatively low year-to-date pre-tax income in the first half of 2016.equity compensation.

The Company establishes reserves when it is more likely than not that the Company will not realize the full tax benefit of a position. The Company had a reserve of $2.4 million for uncertain tax positions as of ~~June 17, 2017~~March 24, 2018 and December ~~31, 2016~~30, 2017. The gross unrecognized tax benefits would, if recognized, decrease the Company's effective tax rate.

(13) SHARE-BASED COMPENSATION

The aggregate number of shares of common stock which may be issued under the Company’s 2008 Omnibus Plan ("Plan") is ~~1,902,077~~2,602,077 plus any common stock that becomes available for issuance pursuant to the reusage provision of the Plan. As of ~~June 17, 2017~~March 24, 2018, the number of shares available for issuance under the Plan was ~~725,361~~536,953 shares.

Restricted Stock Compensation/Awards

Annually, the Company grants restricted shares to its Board of Directors. The shares become fully vested one year from their grant date. The fair value of each restricted stock grant is based on the closing price of the Company's common stock on the date of grant. The Company amortizes the expense over the service period, which is the fiscal year in which the award is granted. In addition, the Company may grant restricted shares to certain members of management based on their services and contingent upon continued service with the Company. The restricted shares vest over a period of approximately three years from the grant date. The fair value of each restricted stock grant is based on the closing price of the Company's common stock on the date of grant.

The following table shows a summary of restricted ~~shares~~share grants and expense resulting from the awards:

In February 2017, as part of Mr. Recatto's employment agreement, the Company granted a restricted stock award of 500,000 shares of common stock, which vests through January 2021 in an amount based on the vesting table below, with the common stock price increase to be determined based on the increase in the price of the Company’s common stock (if any) from the closing price of the common stock as reported by Nasdaq on the employment commencement date ($15.00) and the common stock price on the potential vesting date (determined by using the weighted average closing price of a share of the Company's common stock for the 90-day period ending on the vesting date). If the stock price does not increase by ~~$5,~~$5.00, then no shares shall vest. During the first ~~half~~quarter of fiscal ~~2017,~~2018, the Company recorded approximately $0.5 million of compensation expense, which includes $0.2 million of expense from the recognition of an accelerated vesting, related to this award. In the future, the Company expects to recognize compensation expense of approximately ~~$3.1~~$1.9 million over the remaining requisite service period, which ends January ~~31,~~3

1, 2021. The fair value of this restricted stock award as of the grant date was estimated using a Monte Carlo simulation model. Key assumptions used in the Monte Carlo simulation to estimate the grant date fair value of this award are a risk-free rate of 1.70%, expected dividend yield of zero, and an expected volatility assumption of 41.73%.

Provision for possible accelerated vesting of award

If the ~~weighted~~ average closing price of the Company's common stock increases by the marginal levels set forth in the above vesting table for any consecutive 180 ~~consecutive days during any~~day period between the award date and final vesting date, Mr. Recatto shall become vested in 50% of the corresponding total percentage of restricted shares earned on the last day of the 180 day period. On March 14, 2018, the weighted average closing price of the Company's common stock met the 25% marginal level and Mr. Recatto became fully vested in half of the 125,000 vested shares.

The following table summarizes the restricted stock activity for the period ended ~~June 17, 2017~~March 24, 2018:

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Disclosure Regarding Forward-Looking Statements

You should read the following discussion in conjunction with our consolidated financial statements and related notes in our Annual Report on Form 10-K filed with the SEC on March ~~3, 2017~~1, 2018. In addition to historical information, this discussion contains forward-looking statements that involve risks, uncertainties and assumptions that could cause actual results to differ materially from our expectations. These statements can be identified by the fact that they do not relate strictly to historical or current facts. They use words such as "aim," "anticipate," "believe," "could," "estimate," "expect," "intend," "may," "plan," "project," "should," "will be," "will continue," "will likely result," "would" and other words and terms of similar meaning in conjunction with a discussion of future or estimated operating or financial performance.

Overview

We provide parts cleaning, containerized waste management, used oil collection, vacuum truck services, antifreeze recycling, and field services primarily to small and medium sized industrial customers as well as vehicle maintenance customers. We own and operate a used oil re-refinery, several wastewater treatment plants and multiple antifreeze recycling facilities. We believe we are the second largest provider of industrial and hazardous waste services to small and mid-sized customers in both the vehicle maintenance and manufacturing services sector in North America, and we have the second largest used oil re-refining capacity in North America. Our services help our customers manage their used chemicals and liquid and solid wastes while also helping to minimize their regulatory burdens. We operate from a network of 8387 branch facilities providing services to customers in 45 states and parts of Canada. We conduct business through two ~~operating~~ segments: Environmental Services and Oil Business.

Our Environmental Services segment revenues are generated primarily from providing parts cleaning services, containerized waste management, vacuum truck services, antifreeze recycling, and field services. Revenues from this segment accounted for approximately ~~65%~~69% of our total ~~company~~Company revenues for the first ~~half~~quarter of fiscal ~~2017~~2018. In the Environmental Services segment, we define and measure same-branch revenues for a given period as the subset of all our branches that have been open and operating throughout and between the periods being compared, and we refer to these as established branches. We calculate average revenues per working day by dividing our revenues by the number of non-holiday weekdays in the applicable fiscal year or fiscal quarter.

Our Oil Business segment consists of our used oil collection, used oil re-refining activities, and recycled fuel oil ("RFO") sales which accounted for approximately ~~35%~~31% of our total ~~company~~Company revenues in the first ~~half~~quarter of fiscal ~~2017.~~2018.

Our operating costs include the costs of the materials we use in our products and services, such as used oil collected from customers or purchased from third party collectors, solvent, and other chemicals. The used solvent that we retrieve from customers in our product reuse program is accounted for as a reduction in our net cost of solvent under operating costs, whether placed in inventory or sold to a purchaser for reuse. Changes in the price of crude oil can impact operating costs indirectly as it may impact the price we pay for solvent or used oil, although we attempt to offset volatility in the oil markets by managing the spread between the costs we pay for our materials and the prices we charge for our products and services. Operating costs also include transportation of solvents and waste, payments to third parties to recycle or dispose of the waste materials that we collect, and the costs of operating our re-refinery, recycling centers, hubs, and branch system including personnel costs (including commissions), facility rent, truck leases, fuel, and maintenance. Our operating costs as a percentage of sales

generally increase in relation to the number of new branch openings. As new branches achieve route density and scale efficiencies, our operating costs as a percentage of sales generally decrease.

We use profit before corporate selling, general, and administrative expenses ("SG&A") as a key measure of segment profitability. We define profit before corporate SG&A expense as revenue less operating costs and depreciation and amortization from operations.

Our corporate selling, general, and administrative expenses include the costs of performing centralized business functions, including sales management at or above the regional level, business management, billing, receivables management, accounting and finance, information technology, environmental health and safety, and legal.

We operate a used oil re-refinery located in Indianapolis, Indiana, through which we recycle used oil into high quality lubricant base oil and other products. We supply the base oil to firms that produce and market finished lubricants. Our re-refinery has an annual nameplate capacity of approximately 75 million gallons of used oil feedstock, allowing it to produce approximately 4547 million gallons of lubricating base oil per year when operating at full capacity.

Critical Accounting Policies

Critical accounting policies are those that are both important to the accurate portrayal of a company’s financial condition and results and require subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

In order to prepare financial statements that conform to accounting principles generally accepted in the United States, commonly referred to as GAAP, we make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. Certain estimates are particularly sensitive due to their significance to the financial statements and the possibility that future events may be significantly different from our expectations.

~~With the exception of the adoption of ASU 2016-09 described in Note 2 "Summary of Significant Accounting Policies," there~~There were no material changes during the first ~~half~~quarter of fiscal ~~2017~~2018 to the information provided under the heading "Critical Accounting Policies" included in our Annual Report on Form 10-K for the fiscal year ended December ~~31, 2016.~~30, 2017 with the exception of revenue recognition. See footnote 3 - Revenue for more information.

Revenues

For the ~~second~~first quarter of fiscal 2018, revenues increased $2.7 million, or 3.3%, from $80.5 million in the first quarter of fiscal 2017~~, revenues increased~~ ~~$5.8~~ to $83.1 million~~, or~~ ~~7.2%, from~~ ~~$80.6 million~~ in the ~~second~~first quarter of fiscal ~~2016~~ to ~~$86.4 million~~ ~~in the second quarter of fiscal~~ ~~2017~~2018. ~~For the first half of fiscal 2017, revenues increased $7.8 million, or 4.9%, from $159.0 million~~The growth in ~~the first half of fiscal 2016 to $166.8 million in the first half of fiscal 2017. The increase in revenues~~revenue was mainly driven by ~~higher Oil Business segment revenues~~an 8.0% year over year ~~due to higher pricing for~~increase in our ~~base oil products, partially offset by lower used oil pick-up charges.

Operating expenses

Operating costs

Operating costs increased $~~1.6~~7.1 million, or ~~2.5%~~11.6%, from the ~~second quarter of fiscal~~ ~~2016~~ ~~to the second~~first quarter of fiscal 2017 compared to the first quarter of fiscal 2018. The largest portion of this increase was due to an increase in ~~the amount paid~~disposal costs, increased costs in labor, and higher transportation costs. Higher expenses for disposal and transportation were, in part, due to ~~vendors for used oil delivered directly to~~extended downtime at our ~~re-refinery. Operating~~re-refinery and an outage at one of our main third-party disposal vendors. Higher labor costs ~~decreased $1.4 million, or 1.1%, from the first half of fiscal 2016 to the first half of fiscal 2017. The decrease in operating costs for the first half of 2017 compared to the first half of 2016 was~~were primarily due to improved route truck productivity, the absence of inventory write-downs such as we incurred in the first half of fiscal 2016, and lower net solvent and disposal costs, partially offset by higher prices paid for used oil delivered directlyadditional resources to support our ~~re-refinery, and higher labor expenses.~~growth initiatives.

We expect that in the future our operating costs in the Environmental Services business will continue to increase as our service volume ~~increases,~~increases; however, a decrease in crude oil prices could partially offset this cost increase because a decrease in price could cause a decline in the price we pay for parts cleaning solvent and diesel fuel. Likewise, an increase in crude oil prices could cause an increase in the price we pay for parts cleaning solvent and diesel fuel. In the Oil Business segment, our operating costs could increase or decrease in the future depending on changes in the price for crude oil which could directly impact our used oil collection costs and processing costs at our re-refinery.

Selling, general, and administrative expenses

Selling, general, and administrative expenses decreased $~~0.9~~1.3 million, or ~~8.2%~~10.7%, from the ~~second quarter of fiscal~~ ~~2016~~ ~~to the second~~first quarter of fiscal 2017~~. Selling, general, and administrative expenses decreased $0.8 million, or 3.4%, from the first half of fiscal 2016~~ to the first ~~half~~quarter of fiscal ~~2017.~~2018. The decrease in expense was mainly driven by lower legal fees and lower expense for incentive compensation, partially offset by higher ~~incentive compensation and share-based compensation~~bad debt expense.

Other expense (income) - net

Other expense (income) - net was ~~$3.0~~$0.4 million of expense for the first quarter of fiscal 2018 compared to income of $5.0 million for the ~~second~~first quarter of fiscal ~~2017 compared to approximately $0.1 million of other (income) - net~~2017. Other expense for the ~~second~~first quarter of fiscal ~~2016.~~2018 was mainly driven by $0.3 million of site closure costs for a facility in Wilmington, DE. Other income for the ~~second~~first quarter of fiscal 2017 was mainly driven by a ~~gain~~partial award of ~~$3.6~~$5.1 million ~~generated as a result of a settlement agreement~~from the arbitration related to our acquisition of FCC Environmental in 2014. Other (income) - net was $8.0 million for the first half of fiscal 2017 compared to approximately $0.2 million of other (income) - net for the first half of fiscal 2016. The first half of fiscal 2017 includes a gain of $5.1 million received in the first quarter of fiscal 2017 as a result of having received a partial award for a claim made in arbitration and a gain of $3.6 million received during the second quarter of fiscal 2017 from a settlement agreement, both of which were related to our acquisition of FCC Environmental, LLC and International Petroleum Corp. of Delaware in 2014.

Interest expense - net

Net interest expense for the ~~second~~first quarter of fiscal ~~2017~~2018 was ~~$0.4~~$0.2 million compared to interest expense of ~~$0.5~~$0.1 million in the ~~second~~first quarter of fiscal 2016. In the first half of fiscal 2017 we recorded interest expense of $0.9 million as a result of our Term Loan, partially offset by $0.4 million of interest income we received as part of our award from the arbitration related to our acquisition of FCC Environmental in 2014. Interest expense was $1.0 million for the first half of 2016.2017.

Provision for income taxes

The Company's effective tax rate for the ~~second~~first quarter of fiscal ~~2017~~2018 was ~~36.3%~~81.1% compared to 36.7% in the ~~second~~first quarter of fiscal ~~2016. The Company’s effective rate for the first half of fiscal 2017 was 36.5% compared to 65.0% in the first half of fiscal 2016.~~2017. The rate ~~decrease~~difference is ~~primarily attributed~~principally attributable to the ~~previous year’s first half effect~~differing treatment for financial reporting and income tax reporting of certain state income taxes which are computed on a tax base that reflects substantial modifications to federal taxable income, and that had created comparatively high tax expense due to relatively low year-to-date pre-tax income in the first half of 2016.equity compensation.

Environmental Services profit before corporate SG&A expense ~~increased $1.6~~decreased $1.7 million, or ~~10.6%~~11.3%, in the ~~second~~first quarter of fiscal 2018 compared to the first quarter of fiscal 2017 ~~compared to the second quarter of fiscal~~ ~~2016. Environmental Services profit before corporate SG&A expense increased $2.7 million, or 9.3%, in the first half of fiscal 2017 compared to the first half of fiscal 2016~~ primarily due to higher ~~revenue, lower~~ disposal costs, ~~lower worker's compensation,~~the addition of sales and ~~the absence of inventory write-downs, partially offset by~~service resources, and higher ~~service labor in the first half of fiscal 2017 compared to the first half of fiscal 2016.~~transportation charges.

Oil Business (loss) income before corporate SG&A expense ~~increased~~decreased $~~2.6~~2.3 million, in the ~~second~~first quarter of fiscal 2018 compared to the first quarter of fiscal 2017~~, compared~~ mainly due to ~~the second quarter of fiscal~~ ~~2016. Oil Business income before corporate SG&A expense increased $6.5 million in the first half of fiscal~~ ~~2017, compared to the first half of fiscal~~ ~~2016. These improvements were primarily driven by the increase in the selling price~~higher costs for base oil , as well as improved productivity from our oil collection routes during the first half of fiscal 2017 compared to the first half of fiscal 2016. These improvements were partially offset by lower sales volume of base oil and RFO products as well as lower pricing for our used oil ~~collection service during the first half of fiscal 2017 compared~~feedstock, higher maintenance costs and lower production volume due to ~~the first half of fiscal 2016.~~re-refinery downtime and higher cleanup costs due to site closure activities.

FINANCIAL CONDITION

Liquidity and Capital Resources

Cash and Cash Equivalents

As of ~~June 17, 2017~~March 24, 2018 and December ~~31, 2016~~30, 2017, cash and cash equivalents were ~~$25.2~~$37.6 million and $~~36.6~~41.9 million, respectively. Our primary sources of liquidity are cash flows from operations and funds available to borrow under our term loan and revolving bank credit facility. ~~During the first half of 2017, the Company used approximately $34.2 million of cash to pay down debt as part of entering into a new Credit Agreement.~~

Debt and Financing Arrangements

~~On February 21, 2017, the Company entered into a new~~The Company's Credit Agreement as amended ("Credit Agreement") ~~replacing the prior Credit Agreement ("Prior Credit Agreement") dated as of June 29, 2015. The Credit Agreement~~, provides for borrowings of up to $95.0 million, subject to the satisfaction of certain terms and conditions, comprised of a term loan of $30.0 million and up to $65.0 million of borrowings under the revolving loan portion. The actual amount available under the revolving loan portion of the Credit Agreement is limited by the Company's total leverage ratio. The amount available to draw at any point in time would be further reduced by any standby letters of credit issued.

Loans made under the Credit Agreement may be Base Rate Loans or LIBOR Rate Loans, at the election of the Company subject to certain exceptions. Base Rate Loans have an interest rate equal to (i) the higher of (a) the federal funds rate plus 0.5%, (b) the London Interbank Offering Rate (“LIBOR”) plus 1%, or (c) Bank of America's prime rate, plus (ii) a variable margin of between 0.75% and 1.75% depending on the Company's total leverage ratio, calculated on a consolidated basis. LIBOR rate loans have an interest rate equal to (i) the LIBOR rate plus (ii) a variable margin of between 1.75% and 2.75% depending on the Company's total leverage ratio. Amounts borrowed under the Credit Agreement are secured by a security interest in substantially all of the Company's tangible and intangible assets. In June 2017, the Company entered into a First Amendment to the Credit Agreement that expands the Company's ability to make dispositions without bank group approval.

~~As of the Effective date of the~~The Credit ~~Agreement February 21, 2017, the effective interest rate on the Term A loan was 3.28% and the effective rate on the revolving loan was 3.28%.~~

~~The~~ Agreement contains customary terms and provisions (including representations, covenants, and conditions) for transactions of this type. Certain covenants, among other things, restrict the Company's and its ~~Subsidiaries'~~subsidiaries' ability to incur indebtedness, grant liens, make investments and sell assets. The Credit Agreement contains customary events of default, covenants and representations and warranties. Financial covenants include:

An interest coverage ratio (based on interest expense and EBITDA) of at least 3.5 to 1.0;

A capital expenditures covenant limiting capital expenditures to $100.0 million plus, if the capital expenditures permitted have been fully utilized, an additional amount for the remaining term of the Agreement equal to 35% of EBITDA for the thirteen “four-week” periods most recently ended immediately prior to the full utilization of such $100.0 million ~~basket~~basket.

As of ~~June 17, 2017~~March 24, 2018 and December ~~31, 2016,~~30, 2017, the Company was in compliance with all covenants under ~~both~~the Credit ~~Agreements.~~Agreement. As of ~~June 17, 2017~~March 24, 2018 and December ~~31, 2016,~~30, 2017, the Company had ~~$2.4~~$1.2 million and ~~$3.0~~$0.9 million of standby letters of credit issued, respectively, and ~~$62.6~~$63.8 million and ~~$27.6~~$64.1 million was available for borrowing under the ~~Credit Facility,~~bank credit facility, respectively. The actual amount available under the revolving loan portion of the Credit Agreement is limited by the Company's total leverage ratio.

The Company's weighted average interest rate for all debt as of ~~June 17,~~March 24, 2018 and March 25, 2017 was 3.4% and ~~June 18, 2016 was 3.8% and 3.2%~~3.5%, respectively. As of ~~June 17, 2017,~~March 24, 2018, the Company had $30.0 million outstanding under the term loan, and no amount outstanding under the revolving credit facility.

We believe that our existing cash, cash equivalents, available borrowings, and other sources of financings will be sufficient to meet our anticipated cash needs for working capital and capital expenditures for at least the next 12 months. We cannot assure you that this will be the case or that our assumptions regarding revenues and expenses underlying this belief will be accurate. If, in the future, we require more liquidity than is available to us under our credit facility, we may need to raise additional funds through debt or equity offerings. Adequate funds may not be available when needed or may not be available on terms favorable to us. If additional funds are raised by issuing equity securities, dilution to existing stockholders may result. If we raise additional funds by obtaining loans from third parties, the terms of those financing arrangements may include negative covenants or other restrictions on our business that could impair our operational flexibility, and would also require us to fund additional interest expense. If funding is insufficient at any time in the future, we may be unable to develop or enhance our products or services, take advantage of business opportunities, or respond to competitive pressures, any of which could have a material adverse effect on our business, financial condition and results of operations.

Accounts Receivable — The ~~decrease~~increase in accounts receivable had ~~a favorable~~an unfavorable impact on cash provided by operating activities of ~~$5.1~~$6.1 million in the first ~~half~~quarter of fiscal ~~2017~~2018 compared to the first ~~half~~quarter of fiscal ~~2016 primarily~~2017 mainly due to a one-time receipt of $4.3 million related to a settlement agreement with the sellers of FCC ~~Environmental.~~Environmental in the first quarter of 2017.

Accounts Payable — The increase in accounts payable favorably affected cash flows from operating activities by $5.0 million in the first quarter of fiscal 2018 compared to the first quarter of fiscal 2017.

During the first ~~half~~quarter of fiscal ~~2017,~~2018, we spent ~~$2.6~~$0.8 million for capital improvements to the re-refinery, compared to ~~$4.8~~$1.0 million on capital improvements at the re-refinery in the first ~~half~~quarter of fiscal ~~2016.~~2017.

~~Proceeds from New Credit Agreement —~~ ~~We received $30 million of proceeds from our new Term Loan.~~

~~Repayment of our Old Credit Agreement —~~ ~~We made $64.2 million of repayments of our prior Term Loan.~~

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to interest rate risks primarily through borrowings under our bank Credit Facility. Interest on this facility is based upon variable interest rates. Our weighted average borrowings under our Credit Facility during the first ~~half~~quarter of fiscal ~~2017~~2018 ~~were $41.1~~was $30.0 million, and the annual effective interest rate for the Credit Facility for the first ~~half~~quarter of fiscal ~~2017~~2018 was ~~3.8%~~3.4%. We currently do not hedge against interest rate risk. Based on the foregoing, a hypothetical 1% increase or decrease in interest rates would have resulted in a change of ~~$0.4~~$0.3 million to our interest expense in the first ~~half~~quarter of fiscal ~~2017.~~2018.
