Notes to Consolidated Condensed Financial Statements

March 31, 2018

(Unaudited)

Reference is made herein to the notes to consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2017.

1. Basis of Presentation

The consolidated condensed financial statements included herein have been prepared by the Company (which may be referred to as we, us or our), without an audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“the Commission”). Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations, although the Company believes the disclosures which are made are adequate to make the information presented not misleading. Further, the consolidated condensed financial statements reflect, in the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position and results of operations as of and for the periods indicated. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of results to be expected for the fiscal year ending December 31, 2018.

The Company suggests that these consolidated condensed financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

2. Summary of Significant Accounting Policies

Our accounting policies are as set forth in the notes to the December 31, 2017 consolidated financial statements referred to above.

Recently Adopted Accounting Standards

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers” followed by a series of related accounting standard updates (collectively referred to as “Topic 606”), which superseded nearly all existing revenue recognition guidance. Topic 606 provides a single, comprehensive revenue recognition model for all contracts with customers. Under the new standard, a five-step process is utilized in order to determine revenue recognition, depicting the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. Topic 606 also requires additional disclosure surrounding the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. Topic 606 is effective for annual reporting periods beginning after December 15, 2017 (including interim reporting periods within those periods). The new standard permits two implementation approaches: the full retrospective method, in which case the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. The Company adopted Topic 606 effective January 1, 2018 under the modified retrospective approach to all contracts as of date of adoption. The Company recognized the cumulative effect of initially adopting Topic 606 as an increase of approximately $317,000 to the opening balance of accumulated deficit at January 1, 2018. The adoption of Topic 606 did not result in significant changes to our revenue recognition model within our Treatment and Services Segments. The cumulative impact to the opening balance of accumulated deficit at January 1, 2018 was primarily driven by changes to the timing of revenue recognition in certain immaterial waste streams within our Treatment Segment. See “Note 3 – Revenue” for additional disclosures related to our revenues under the new standard. The comparative previous period information continues to be reported under the accounting standards in effect for that period. We expect the impact of the adoption of Topic 606 to be immaterial to our consolidated financial statements on an on-going basis.

The cumulative effect of the changes made to our January 1, 2018 unaudited Consolidated Balance Sheet for the adoption of Topic 606 was as follows (in thousands):

	Balance at			Adjustment			Opening balance at
	December 31,			Due to			January 1,

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force),” which aims to eliminate diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other Topics. Subsequently, in November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230), Restricted Cash, a consensus of the FASB Emerging Issues Task Force,” which clarifies the guidance on the cash flow classification and presentation of changes in restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash or restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flow. ASU 2016-15 and ASU 2016-18 are effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017. The adoption of these ASUs by the Company effective January 1, 2018 did not have a material impact on the Company’s financial position, results of operations, or cash flows.

In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory,” which eliminates the existing exception in U.S. GAAP prohibiting the recognition of the income tax consequences for intra-entity asset transfers. Under ASU 2016-16, entities will be required to recognize the income tax consequences of intra-entity asset transfers other than inventory when the transfer occurs. ASU 2016-16 is effective on a modified retrospective basis for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The adoption of ASU 2016-16 by the Company effective January 1, 2018 did not have a material impact on the Company’s financial position, results of operations, or cash flows.

In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805) – Clarifying the Definition of a Business.” ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisition, disposals, goodwill and consolidation. This standard is effective for fiscal years beginning after December 15, 2017, including interim periods within that reporting period. The adoption of ASU 2017-01 by the Company effective January 1, 2018 did not have a material impact on the Company’s financial position, results of operations, or cash flows.

In May 2017, the FASB issued ASU 2017-09, “Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting.” This ASU provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU 2017-09 is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years, and early adoption is permitted, including in an interim period. ASU 2017-09 is to be applied on a prospective basis to an award modified on or after the adoption date. The adoption of ASU 2017-01 by the Company effective January 1, 2018 did not have a material impact on the Company’s financial position, results of operations, or cash flows.

Recently Issued Accounting Standards – Not Yet Adopted

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. This ASU is effective January 1, 2019 for the Company. The Company is still evaluating the potential impact of adopting this guidance on our financial statements.

In February 2018, FASB issued ASU 2018-02, “Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”. This ASU allows for the reclassification of certain income tax effects related to the Tax Cuts and Jobs Act between “Accumulated other comprehensive income” and “Retained earnings.” This ASU relates to the requirement that adjustments to deferred tax liabilities and assets related to a change in tax laws or rates to be included in “Income from continuing operations”, even in situations where the related items were originally recognized in “Other comprehensive income” (rather than in “Income from continuing operations”). ASU 2018-02 is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. Adoption of this ASU is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the tax laws or rates were recognized. The Company is currently assessing the impact that this standard will have on its financial statements.

3. Revenue

The Company accounts for revenue in accordance with ASC Topic 606, which we adopted on January 1, 2018 using the modified retrospective method. The majority of our revenue is derived from short term contracts with an original expected length of one year or less.

Performance Obligation

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue as the performance obligation is satisfied.

Treatment Segment Revenues:

Contracts in our Treatment Segment have a single performance obligation as the promise to receive, treat and dispose of waste is not separately identifiable in the contract and, therefore, not distinct. Performance obligations are generally satisfied over time using the input method. Under the input method, the Company uses a measure of progress divided into major phases which include receipt, treatment/processing and shipment/final disposal. As major processing phases are completed and the costs are incurred, the proportional percentage of revenue is recognized. Transaction price for Treatment Segment contracts are determined by the stated fixed rate per unit price as stipulated in the contract.

Services Segment Revenues:

Revenues for our Services Segment are generated from time and materials, cost reimbursement or fixed price arrangements:

The Company’s primary obligation to customers in time and materials contracts relate to the provision of services to the customer at the direction of the customer. This provision of services at the request of the customer is the performance obligation, which is satisfied over time. Revenue earned from time and materials contracts is determined using the input method and is based on contractually defined billing rates applied to services performed and materials delivered.

10

The Company’s primary performance obligation to customers in cost reimbursement contracts is to complete certain tasks and work steams. Each specified work stream or task within the contract is considered to be a separate performance obligation. The transaction price is calculated using an estimated cost to complete the various scope items to achieve the performance obligation as stipulated in the contract. An estimate is prepared for each individual scope item in the contract and the transaction price is allocated on a time and materials basis as services are provided. Revenue from cost reimbursement contracts is recognized over time using the input method based on costs incurred, plus a proportionate amount of fee earned.

Under fixed price contracts, the objective of the project is not attained unless all scope items within the contract are completed and all of the services promised within fixed fee contracts constitute a single performance obligation. Transaction price is estimated based upon the estimated cost to complete the overall project. Revenue from fixed price contract is recognized over time using the output method based on the percentage of project completion multiplied by the total fee as a measure of progress.

The nature of our contracts does not give rise to variable considerations.

Significant Payment Terms

Invoicing is based on schedules established in customer contracts. Payment terms vary by customers but are generally established at 30 days from invoicing.

Disaggregation of Revenue

In general, the Company’s business segmentation is aligned according to the nature and economic characteristics of our services and provides meaningful disaggregation of each business segment’s results of operations. The following tables present further disaggregation of our revenues by different categories for our Services and Treatment Segments:

	Three Months Ended						Three Months Ended
Revenue by Contract Type	March 31, 2018						March 31, 2017
(In thousands)	Treatment		Services		Total		Treatment		Services		Total

Contract Balances

The timing of revenue recognition, billings, and cash collections results in accounts receivable and unbilled receivables (contract assets). The Company’s contract liabilities consist of deferred revenues which represents advance payment from customers in advance of the completion of our performance obligation.

11

The following table represents changes in our contract assets and contract liabilities balances:

(In thousands)	March 31, 2018		January 1, 2018		Year-to-date Change ($)			Year-to-date Change (%)
Contract assets
Account receivables, net of allowance	$	4,762	$	7,940	$	(3,178	)		(40.0	)%
Unbilled receivables - current		4,574		4,547		27			0.6	%
Unbilled receivables - non-current		92		184		(92	)		(50.0	)%
Contract liabilities
Deferred revenue	$	4,620	$	5,083	$	(463	)		(9.1	)%

The net decrease in our contract assets was primarily due to increased accounts receivable collections. The Company provides various payment terms to our customers; therefore, our accounts receivable are impacted by these terms and the related timing of accounts receivable collections.

Revenue recognized for the three months ended March 31, 2018 and 2017 that was included in the contract liability balance at the beginning of each year was $3,811,000 and $2,977,000, respectively. All revenue recognized in each period related to performance obligations satisfied within the respective period.

Incremental Costs to Obtain a Contract

Costs incurred to obtain contracts with our customers are immaterial and as a result, the Company expenses (within selling, general and administration expenses (“SG&A”)) incremental costs incurred in obtaining contracts with our customer as incurred.

Remaining Performance Obligations

The Company applies the practical expedient in paragraph 606-10-50-14 and does not disclose information about remaining performance obligations that have original expected durations of one year or less.

The Company applies the transition practical expedient in paragraph 606-10-65-1(f)(3) and does not disclose the amount of the transaction price allocated to the remaining performance obligations or an explanation of when the Company expects to recognize that amount as revenue for periods prior to the adoption of Topic 606.

4. Intangible Assets

Total			$	4,998	$	(3,517	)	$	1,481	$	4,982	$	(3,433	)	$	1,549

The intangible assets noted above are amortized on a straight-line basis over their useful lives with the exception of customer relationships which are being amortized using an accelerated method. The Company has only one definite-lived permit that is subject to amortization.

12

The following table summarizes the expected amortization over the next five years for our definite-lived intangible assets (including the one definite-lived permit):

5. Capital Stock, Stock Plans and Stock Based Compensation

The Company has certain stock option plans under which it awards incentive and non-qualified stock options to employees, officers, and outside directors.

On January 18, 2018, the Company granted 6,000 options from the Company’s 2003 Outside Directors Stock Plan to a new director elected by the Company’s Board of Directors (“Board”) to fill a vacancy on the Board. The options granted were for a contractual term of ten years with a vesting period of six months. The exercise price of the options was $4.05 per share, which was equal to our closing stock price the day preceding the grant date, pursuant to the 2003 Outside Directors Stock Plan.

On January 13, 2017, the Company granted 6,000 options from the Company’s 2003 Outside Directors Stock Plan to a new director elected by the Company’s Board to fill a vacancy left by Jack Lahav who retired from the Board in October 2016. The options granted were for a contractual term of ten years with a vesting period of six months. The exercise price of the options was $3.79 per share, which was equal to our closing stock price the day preceding the grant date, pursuant to the 2003 Outside Directors Stock Plan.

The Company estimates fair value of stock options using the Black-Scholes valuation model. Assumptions used to estimate the fair value of stock options granted include the exercise price of the award, the expected term, the expected volatility of the Company’s stock over the option’s expected term, the risk-free interest rate over the option’s expected term, and the expected annual dividend yield. The fair value of the options granted on January 18, 2018 and January 13, 2017 as discussed above and the related assumptions used in the Black-Scholes option model used to value the options granted were as follows:

	Outside Director Stock Options Granted
	January 18, 2018			January 13, 2017
Weighted-average fair value per option	$	2.55		$	2.63
Risk -free interest rate (1)		2.62	%		2.40	%
Expected volatility of stock (2)		57.29	%		56.32	%
Dividend yield		None			None
Expected option life (3)		10.0 years			10.0 years

(1)	The risk-free interest rate is based on the U.S. Treasury yield in effect at the grant date over the expected term of the option.
(2)	The expected volatility is based on historical volatility from our traded Common Stock over the expected term of the option.
(3)	The expected option life is based on historical exercises and post-vesting data.

13

The following table summarizes stock-based compensation recognized for the three months ended March 31, 2018 and 2017 for our employee and director stock options.

	Three Months Ended March 31,

6. (Income) Loss Per Share

Basic income (loss) per share is calculated based on the weighted-average number of outstanding common shares during the applicable period. Diluted income (loss) per share is based on the weighted-average number of outstanding common shares plus the weighted-average number of potential outstanding common shares. In periods where they are anti-dilutive, such amounts are excluded from the calculations of dilutive earnings per shares. The following table reconciles the income (loss) and average share amounts used to compute both basic and diluted income (loss) per share:

	Three Months Ended (Unaudited)

Revolving Credit and Term Loan Agreement

The Company entered into an Amended and Restated Revolving Credit, Term Loan and Security Agreement, dated October 31, 2011 (“Amended Loan Agreement”), with PNC National Association (“PNC”), acting as agent and lender. The Amended Loan Agreement has been amended from time to time since the execution of the Amended Loan Agreement. The Amended Loan Agreement, as subsequently amended (“Revised Loan Agreement”), provides the Company with the following credit facility with a maturity date of March 24, 2021: (a) up to $12,000,000 revolving credit (“revolving credit”) and (b) a term loan (“term loan”) of approximately $6,100,000, which requires monthly installments of approximately $101,600 (based on a seven-year amortization). The maximum that we can borrow under the revolving credit is based on a percentage of eligible receivables (as defined) at any one time reduced by outstanding standby letters of credit and borrowing reductions that our lender may impose from time to time.

Under the Revised Loan Agreement, we have the option of paying an annual rate of interest due on the revolving credit at prime plus 2% or London Inter Bank Offer Rate (“LIBOR”) plus 3% and the term loan at prime plus 2.5% or LIBOR plus 3.5%.

Pursuant to the Revised Loan Agreement, the Company may terminate the Revised Loan Agreement, upon 90 days’ prior written notice upon payment in full of its obligations under the Revised Loan Agreement. The Company agreed to pay PNC 1.0% of the total financing had the Company paid off its obligations on or before March 23, 2017, .50% of the total financing had the Company paid off its obligations after March 23, 2017 but prior to or on March 23, 2018, and .25% of the total financing if the Company pays off its obligations after March 23, 2018 but prior to or on March 23, 2019. No early termination fee shall apply if the Company pays off its obligations after March 23, 2019.

At March 31, 2018, the borrowing availability under our revolving credit was approximately $2,823,000, based on our eligible receivables and includes an indefinite reduction of borrowing availability of $2,000,000 that the Company’s lender has imposed. Our borrowing availability under our revolving credit was also reduced by outstanding standby letters of credit totaling approximately $2,660,000.

The Company’s credit facility with PNC contains certain financial covenants, along with customary representations and warranties. A breach of any of these financial covenants, unless waived by PNC, could result in a default under our credit facility allowing our lender to immediately require the repayment of all outstanding debt under our credit facility and terminate all commitments to extend further credit. The Company met its quarterly financial covenants in the first quarter of 2018 and expects to meet its quarterly financial covenants in each of the remaining quarters of 2018 and into the first half of 2019.

8. East Tennessee Materials and Energy Corporation (“M&EC”)

The Company continues its plan to close its M&EC facility by the end of the M&EC’s amended lease term of June 30, 2018. Operations at the M&EC facility are limited during the remaining term of the lease and the facility continues to transition waste shipments and operational capabilities to our other Treatment Segment facilities, subject to customer requirements and regulatory approvals. Simultaneously, the Company continues with closure and decommissioning activities in accordance with M&EC’s license and permit requirements.

At March 31, 2018, total accrued closure liabilities for our M&EC subsidiary totaled approximately $1,864,000 which are recorded as current liabilities. The following reflects changes to the closure liabilities for the M&EC facility from year end 2017:

9. Commitments and Contingencies

Hazardous Waste

In connection with our waste management services, we process both hazardous and non-hazardous waste, which we transport to our own, or other, facilities for destruction or disposal. As a result of disposing of hazardous substances, in the event any cleanup is required, we could be a potentially responsible party for the costs of the cleanup notwithstanding any absence of fault on our part.

Legal Matters

In the normal course of conducting our business, we are involved in various litigation. We are not a party to any litigation or governmental proceeding which our management believes could result in any judgments or fines against us that would have a material adverse effect on our financial position, liquidity or results of future operations.

Insurance

The Company has a 25-year finite risk insurance policy entered into in June 2003 with American International Group, Inc. (“AIG”), which provides financial assurance to the applicable states for our permitted facilities in the event of unforeseen closure. The policy, as amended, provides for a maximum allowable coverage of $39,000,000 and has available capacity to allow for annual inflation and other performance and surety bond requirements. At March 31, 2018, our financial assurance coverage amount under this policy totaled approximately $29,911,000. The Company has recorded $15,726,000 and $15,676,000 in sinking funds related to this policy in other long term assets on the accompanying Consolidated Balance Sheets at March 31, 2018 and December 31, 2017, respectively, which includes interest earned of $1,255,000 and $1,205,000 on the sinking funds as of March 31, 2018 and December 31, 2017, respectively. Interest income for the three months ended March 31, 2018 and 2017 was approximately $50,000 and $27,000, respectively. If the Company so elects, AIG is obligated to pay the Company an amount equal to 100% of the sinking fund account balance in return for complete release of liability from both the Company and any applicable regulatory agency using this policy as an instrument to comply with financial assurance requirements.

Letter of Credits and Bonding Requirements

From time to time, the Company is required to post standby letters of credit and various bonds to support contractual obligations to customers and other obligations, including facility closures. At March 31, 2018, the total amount of standby letters of credit outstanding totaled approximately $2,660,000 and the total amount of bonds outstanding totaled approximately $8,767,000.

10. Discontinued Operations

The Company’s discontinued operations consist of all our subsidiaries included in our Industrial Segment: (1) subsidiaries divested in 2011 and prior, (2) two previously closed locations, and (3) our PFSG facility which is currently undergoing closure, subject to final regulatory approval.

12. Income Taxes

The Company uses an estimated annual effective tax rate, which is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which the Company operates, to determine its quarterly provision for income taxes.

Income tax expenses were $51,000 and $81,000 for continuing operations for the three months ended March 31, 2018 and the corresponding period of 2017, respectively. The Company’s effective tax rate was approximately (16.8%) for the three months ended March 31, 2018 as compared to a tax rate of approximately (13.6%) for the corresponding period of 2017.

13. Management Incentive Plans (“MIPs”)

On January 18, 2018, the Company’s Board and Compensation and Stock Option Committee (the “Compensation Committee”) approved individual MIPs for the (“CEO”), Chief Financial Officer (“CFO”), and Executive Vice President (“EVP”) of Strategic Initiatives. Each MIP is effective January 1, 2018 and applicable for the year ended December 31, 2018. Each MIP provides guidelines for the calculation of annual cash incentive based compensation, subject to Compensation Committee oversight and modification. Each MIP awards cash compensation based on achievement of performance thresholds, with the amount of such compensation established as a percentage of the executive’s annual 2018 base salary on the approval date of the MIP. The potential target performance compensation ranges from 5% to 100% of the 2018 base salary for the CEO ($13,350 to $267,000), 5% to 100% of the 2018 base salary for the CFO ($11,475 to $229,494), and 5% to 100% of the 2018 base salary for the EVP of Strategic Initiatives ($11,170 to $223,400).

14. Subsequent Events

M&EC Series B Preferred Stock

The Series B Preferred Stock (the “Series B Preferred Stock”) of the Company’s consolidated subsidiary, M&EC, is non-voting and non-convertible, has a $1.00 liquidation preference per share and may be redeemed at the option and sole discretion of M&EC at any time, and from time to time, from and after one year from the date of issuance of the Series B Preferred Stock for the purchase price of $1.00. Holders of shares of M&EC Series B Preferred Stock are entitled to receive, when, as and if declared by M&EC’s board of directors out of funds legally available for payment, cumulative dividends at the rate per annum of 5% per share on the liquidation preference of $1.00 per share of Series B Preferred Stock. Dividends on the Series B Preferred Stock shall accrue without interest beginning one year from the date of original issuance (June 25, 2001), and shall be payable in cash, if, when, and as declared by M&EC board, quarterly each year commencing on the first dividend due date following the expiration of one year from the date of original issuance. On April 24, 2018, the Company announced a private exchange offer (“Exchange Offer”), to all holders of the M&EC Series B Preferred Stock , to exchange, for every share of Series B Preferred Stock tendered, (a) 0.1050805 shares of newly issued common stock of the Company, par value $.001 per share (“Common Stock”), and (b) cash in lieu of fractional shares of Common Stock that would otherwise be issuable to the tendering holder of Series B Preferred Stock, in an amount equal to such fractional share of Common Stock multiplied by the closing price per share of the Common Stock on the last trading day immediately preceding the expiration date of the Exchange Offer. The Exchange Offer is being made on an all-or-none basis, for all 1,284,730 shares of Series B Preferred Stock outstanding and has an expiration date of May 30, 2018. Assuming all currently outstanding shares of Series B Preferred Stock are tendered for exchange and not validly withdrawn, the Company would issue an amount of its shares of Common Stock not to exceed 135,000. The Company owns 100% of the voting capital stock of M&EC. If the Exchange Offer is consummated, holders of the M&EC Series B Preferred Stock would forfeit all rights of a holder of Series B Preferred Shares, including the right to receive quarterly cash dividends, and the rights to the cumulative accrued and unpaid dividends with M&EC Series B Preferred Stock in the amount of approximately $1,011,000 as of April 1, 2018. M&EC Board has never declared dividends on the Series B Preferred Stock and our credit facility prohibits the payment of cash dividends without the lender’s consent.

The shares of Company common stock to be issued in exchange for shares of M&EC’s Series B Preferred Stock will be issued pursuant to an exemption from registration under the Securities Act of 1933, as amended, and, as a result, will be considered restricted securities that have restrictions on transferability.

This discussion as to an exchange offer does not constitute an offer or an invitation by the Company to participate in the exchange offer in any manner.

Overview

Revenue decreased slightly by $49,000 or 0.4% to $12,658,000 for the three months ended March 31, 2018 from $12,707,000 for the corresponding period of 2017. The decrease was primarily within our Treatment Segment where revenue decreased $1,075,000 or 10.7% primarily due to lower waste volume. Our revenue for the first quarter of 2018 was impacted by the pending closure of our East Tennessee Materials and Energy Corporation (“M&EC”) facility (by June 2018) which generated revenues of approximately $3,379,000 in the first quarter of 2017 as compared to $56,000 in the first quarter of 2018 as we continue to transition waste shipments and operational capabilities to our other Treatment Segment facilities, subject to customer requirements and regulatory approvals. Revenue from our Services Segment increased by $1,026,000 or 38.4%. Gross profit increased $602,000 or 22.1% primarily due to increased revenue in the Services Segment. Selling, General, and Administrative (“SG&A”) expenses decreased $70,000 or 2.5% for the three months ended March 31, 2018 as compared to the corresponding period of 2017.

Business Environment and Outlook

Our Treatment and Services Segments’ business continues to be heavily dependent on services that we provide to governmental clients directly as the contractor or indirectly as a subcontractor. We believe demand for our services will continue to be subject to fluctuations due to a variety of factors beyond our control, including the current economic conditions and the manner in which the government will be required to spend funding to remediate federal sites. In addition, our governmental contracts and subcontracts relating to activities at governmental sites are generally subject to termination or renegotiation on 30 days notice at the government’s option. Significant reductions in the level of governmental funding or specifically mandated levels for different programs that are important to our business could have a material adverse impact on our business, financial position, results of operations and cash flows. As previously disclosed, our Medical Segment reduced its research and development (“R&D”) activities substantially due to the need for capital to fund such activities. Our Medical Segment continues to seek various sources in order to raise this capital. We anticipate that our Medical Segment R&D activities will be limited until the necessary capital is obtained through its own credit facility or additional equity raise. If the Medical Segment is unable to raise the necessary capital, the Medical Segment could be required to further reduce, delay or eliminate its R&D program.

We are continually reviewing operating costs and are committed to further reducing operating costs to bring them in line with revenue levels, when needed. We continue to focus on expansion into both commercial and international markets to increase revenues in our Treatment and Services Segments to offset the uncertainties of government spending in the United States of America.

Results of Operations

The reporting of financial results and pertinent discussions are tailored to three reportable segments: The Treatment, Services, and Medical Segments. Our Medical Segment has not generated any revenue and all costs incurred are included within R&D.

⁽¹⁾ Includes wastes generated by government clients of $407,000 and $0 for the three month ended March 31, 2018 and the corresponding period of 2017, respectively.

Treatment Segment revenue decreased $1,075,000 or 10.7 % for the three months ended March 31, 2018 over the same period in 2017. The revenue decrease was primarily due to lower revenue generated from government clients due to lower waste volume. Our revenue for the first quarter of 2018 was impacted by the pending closure of our M&EC facility which generated revenues of approximately $3,379,000 in the first quarter of 2017 as compared to $56,000 in the first quarter of 2018 as we continue to transition waste shipments and operational capabilities to our other Treatment Segment facilities, subject to customer requirements and regulatory approvals. Services Segment revenue increased by $1,026,000 or 38.4% in the three months ended March 31, 2018 from the corresponding period of 2017. Our Services Segment revenues are project based; as such, the scope, duration and completion of each project varies. As a result, our Services Segment revenues are subject to differences relating to timing and project value.

Cost of Goods Sold

Cost of goods sold decreased $651,000 for the quarter ended March 31, 2018, compared to the quarter ended March 31, 2017, as follows:

			%				%
(In thousands)	2018		Revenue		2017		Revenue		Change
Treatment	$	6,179		69.0	$	7,347		73.2	$	(1,168	)
Services		3,158		85.4		2,641		98.8		517
Total	$	9,337		73.8	$	9,988		78.6	$	(651	)

Cost of goods sold for the Treatment Segment decreased approximately $1,168,000 or 15.9% primarily due to lower revenue. Treatment Segment variable costs decreased by approximately $438,000 primarily in disposal, transportation, material and supplies and lab costs due to lower revenue. Our overall fixed costs were lower by approximately $730,000 resulting from the following: depreciation expense was lower by approximately $768,000 due to the full depreciation of our M&EC facility’s tangible assets in 2017 resulting from the pending closure of the facility by June 2018; regulatory expenses were lower by $21,000; maintenance expense was higher by $16,000; general expense was higher by approximately $23,000 in various categories; and salaries and payroll related expenses were higher by approximately $20,000. Services Segment cost of goods sold increased $517,000 or 19.6% primarily due to the increase in revenue as discussed above. The increase in cost of goods sold was primarily in salaries and payroll related, travel, and outside services expenses totaling approximately $595,000. The overall higher costs were partially offset by lower general expenses of approximately $65,000 in various categories and lower depreciation and amortization expenses of $13,000. Included within cost of goods sold is depreciation and amortization expense of $353,000 and $1,134,000 for the three months ended March 31, 2018, and 2017, respectively.

Gross Profit

Gross profit for the quarter ended March 31, 2018 increased $602,000 over the corresponding period of 2017, as follows:

			%				%
(In thousands)	2018		Revenue		2017		Revenue		Change
Treatment	$	2,780		31.0	$	2,687		26.8	$	93
Services		541		14.6		32		1.2		509
Total	$	3,321		26.2	$	2,719		21.4	$	602

Treatment Segment gross profit increased by $93,000 and gross margin increased to 31.0% from 26.8% primarily due to revenue mix and the reduction in our fixed costs. The increase in gross profit in the Services Segment of $509,000 and gross margin from 1.2% to 14.6% was primarily due to the increase in revenue as discussed above. As discussed previously, our overall Services Segment gross margin is impacted by our current projects which are competitively bid on and will therefore, have varying margin structures.

SG&A

SG&A expenses decreased $70,000 for the three months ended March 31, 2018, as compared to the corresponding period for 2017, as follows:

(In thousands)	2018		% Revenue		2017		% Revenue		Change
Administrative	$	1,225		―	$	1,216		―	$	9
Treatment		922		10.3		896		8.9		26
Services		633		17.1		738		27.6		(105	)
Total	$	2,780		22.0	$	2,850		22.4	$	(70	)

25

The lower SG&A costs were primarily within the Services Segment. Services Segment SG&A was lower primarily due to the following: outside services expenses were lower by approximately $26,000 resulting from fewer consulting/legal matters; salaries and payroll related expenses were lower by approximately $47,000 as in the prior year, our Services Segment incurred higher salary expenses related to bids and proposal work for potential projects; travel expenses were lower by $21,000 and general expenses were lower by approximately $11,000 in various categories. Treatment Segment SG&A was higher primarily due to the following: higher outside services of $47,000 due to more consulting/legal matters; higher general expenses of approximately $71,000 in various categories; higher travel expenses of $10,000; and lower salaries and payroll related expenses of approximately $102,000. The increase in administrative SG&A was primarily due to the following: higher stock-based compensation expenses of approximately $26,000 resulting from options granted to our executive officers in July 2017 and options granted to certain of our employees in October 2017; higher salaries and payroll related expenses by approximately $18,000 ; lower outside services expenses by approximately $26,000 resulting from fewer consulting/business/legal matters; and lower general expenses of approximately $9,000 in various categories. Included in SG&A expenses is depreciation and amortization expense of $19,000 and $21,000 for the three months ended March 31, 2018 and 2017, respectively.

R&D

R&D expenses decreased $157,000 for the three months ended March 31, 2018, as compared to the corresponding period for 2017, as follows:

(In thousands)	2018		2017		Change
Administrative	$	18	$	8	$	10
Treatment		114		181		(67	)
Services		―		―		―
PF Medical		100		200		(100	)
Total	$	232	$	389	$	(157	)

R&D costs consist primarily of employee salaries and benefits, laboratory costs, third party fees, and other related costs associated with the development of new technologies and technological enhancement of new potential waste treatment processes. As disclosed previously, our Medical Segment has ceased a substantial portion of its R&D activities due to the need for substantial capital to fund such activities and we anticipate that our Medical Segment will not resume any substantial R&D activities until it obtains the necessary funding.

Interest Expense

Interest expense decreased approximately $47,000 in the first quarter of 2018 as compared to the corresponding period of 2017 primarily due to lower interest expense from our declining term loan balance and lower average revolver loan balance outstanding.

Discontinued Operations

The Company’s discontinued operations consist of all our subsidiaries included in our Industrial Segment: (1) subsidiaries divested in 2011 and prior, (2) two previously closed locations, and (3) our PFSG facility, which is currently undergoing closure, subject to regulatory approval.

We had net losses of $157,000 and $131,000 for our discontinued operations for the three months ended March 31, 2018 and 2017, respectively (net of taxes of $0 for each period). The losses were primarily due to costs incurred in the administration and continued monitoring of our discontinued operations. Our discontinued operations had no revenues for each of the periods noted above.

26

Liquidity and Capital Resources

Our cash flow requirements during the three months ended March 31, 2018 were primarily financed by our operations and credit facility availability. Our cash flow requirements for the next twelve months will consist primarily of general working capital needs, scheduled principal payments on our debt obligations, remediation projects, planned capital expenditures, and closure spending requirements of approximately $1,864,000 in connection with the pending closure of our M&EC facility. We plan to fund these requirements from our operations and our credit facility availability. Additionally, as a result of the M&EC facility closure, we expect to receive during the second half of 2018, a partial release of approximately $5,000,000 of the $15,726,000 restricted finite risk sinking funds held by American International Group (“AIG”) as collateral under the financial assurance policy dated June 2003 that we currently have with AIG. This partial release of finite risk sinking funds is subject to approval from AIG and the appropriate regulators and when released, we believe will further enhance our liquidity. We continue to explore all sources of increasing revenue. We are continually reviewing operating costs and are committed to further reducing operating costs to bring them in line with revenue levels, when necessary. Although there are no assurances, we believe that our cash flows from operations and our available liquidity from our credit facility are sufficient to fund our operations for the next twelve months. Additionally, the partial release of the finite risk sinking funds that we expect to receive during the second half of 2018 as a result of the M&EC facility closure as discussed above will further provide additional funding for our operations as needed. As previously disclosed, our Medical Segment substantially reduced its R&D activities due to the need for capital to fund such activities. We anticipate that our Medical Segment will not resume full R&D activities until it obtains the necessary funding through obtaining its own credit facility or additional equity raise. Our Medical Segment continues to seek various sources of potential funding. If the Medical Segment is unable to raise the necessary capital, the Medical Segment could be required to further reduce, delay or eliminate its R&D program.

The following table reflects the cash flow activities during the first three months of 2018:

(In thousands)
Cash provided by operating activities of continuing operations	$	2,615
Cash used in operating activities of discontinued operations		(181	)
Cash used in investing activities of continuing operations		(290	)
Cash provided by investing activities of discontinued operations		17
Cash used in financing activities of continuing operations		(304	)
Effect of exchange rate changes in cash		(4	)
Increase in cash	$	1,853

At March 31, 2018, we were in a positive cash position and no revolving credit balance. At March 31, 2018, we had cash on hand of approximately $2,916,000 which includes account balances for our foreign subsidiaries totaling approximately $774,000.

Operating Activities

Accounts receivable, net of allowances for doubtful accounts, totaled $4,762,000 at March 31, 2018, a decrease of $3,178,000 from the December 31, 2017 balance of $7,940,000. The decrease was primarily due to increased accounts receivable collections. We provide a variety of payment terms to our customers; therefore, our accounts receivable are impacted by these terms and the related timing of accounts receivable collections.

Accounts payable, totaled $3,616,000 at March 31, 2018, an increase of $79,000 from the December 31, 2017 balance of $3,537,000. Our accounts payable are impacted by the timing of payment as we are continually managing payment terms with our vendors to maximize our cash position throughout all segments.

Disposal/transportation accrual at March 31, 2018, totaled $1,478,000, a decrease of $593,000 over the December 31, 2017 balance of $2,071,000. Our disposal accrual can vary based on revenue mix and the timing of waste shipments for final disposal. During 2018, we shipped more waste for disposal.

We had a working capital deficit of $2,472,000 (which included working capital of our discontinued operations) at March 31, 2018 as compared to a working capital deficit of $2,268,000 at December 31, 2017. Our working capital was primarily impacted by the decrease in our accounts receivables where our accounts receivable collections outpaced our billings. We anticipate that cash flows to be generated from our operations and the partial release of the restricted finite sinking funds by AIG which we anticipate to receive upon the closure of our M&EC facility as discussed above, will provide improvement to our working capital deficit.

27

Investing Activities

For the three months ended March 31, 2018, our purchases of capital equipment totaled approximately $248,000. These expenditures were primarily for improvements in our Treatment Segment. These capital expenditures were funded by cash from operations. We have budgeted approximately $1,000,000 for 2018 capital expenditures for our Treatment and Services Segments to maintain operations and regulatory compliance requirements. On March 7, 2018, our Board approved an additional $1,000,000 in capital spending for footprint expansion for one of our Treatment Segment facilities. Certain of these budgeted projects may either be delayed until later years or deferred altogether. We have traditionally incurred actual capital spending totals for a given year at less than the initial budgeted amount. We plan to fund our capital expenditures from cash from operations and/or financing. The initiation and timing of projects are also determined by financing alternatives or funds available for such capital projects.

Financing Activities

We entered into an Amended and Restated Revolving Credit, Term Loan and Security Agreement, dated October 31, 2011 (“Amended Loan Agreement”), with PNC National Association (“PNC”), acting as agent and lender. The Amended Loan Agreement, as subsequently amended (“Revised Loan Agreement”), provides us with the following credit facility with a maturity date of March 24, 2021: (a) up to $12,000,000 revolving credit (“revolving credit”) and (b) a term loan (“term loan”) of approximately $6,100,000, which requires monthly installments of approximately $101,600 (based on a seven-year amortization). The maximum that we can borrow under the revolving credit is based on a percentage of eligible receivables (as defined) at any one time reduced by outstanding standby letters of credit and borrowing reductions that our lender may impose from time to time.

Under the Revised Loan Agreement, we have the option of paying an annual rate of interest due on the revolving credit at prime plus 2% or London Inter Bank Offer Rate (“LIBOR”) plus 3% and the term loan at prime plus 2.5% or LIBOR plus 3.5%.

Pursuant to the Revised Loan Agreement, we may terminate the Revised Loan Agreement, upon 90 days’ prior written notice upon payment in full of our obligations under the Revised Loan Agreement. We agreed to pay PNC 1.0% of the total financing had we paid off our obligations on or before March 23, 2017, .50% of the total financing had we paid off our obligations after March 23, 2017 but prior to or on March 23, 2018, and .25% of the total financing if we pay off our obligations after March 23, 2018 but prior to or on March 23, 2019. No early termination fee shall apply if we pay off our obligations after March 23, 2019.

At March 31, 2018, the borrowing availability under our revolving credit was $2,823,000, based on our eligible receivables and includes an indefinite reduction of borrowing availability of $2,000,000 that our lender has imposed. Our borrowing availability under our revolving credit was also reduced by outstanding standby letters of credit totaling approximately $2,660,000.

We have had discussions with our lender as to the removal of the $2,000,000 reduction in borrowing availability discussed above. Our lender has advised us that they will be reducing the $2,000,000 reduction in borrowing availability to $1,000,000 during the first half of 2018, subject to receipt of appropriate approvals by the lender and execution of documentation, and would consider removal of the remaining $1,000,000 reduction in borrowing availability depending on our results during 2018.

Our credit facility with PNC contains certain financial covenants, along with customary representations and warranties. A breach of any of these financial covenants, unless waived by PNC, could result in a default under our credit facility allowing our lender to immediately require the repayment of all outstanding debt under our credit facility and terminate all commitments to extend further credit. The following table details the quarterly financial covenant requirements under our credit facility at March 31, 2018.

28

	Quarterly		1st Quarter
(Dollars in thousands)	Requirement		Actual
Senior Credit Facility
Fixed charge coverage ratio		1.15:1		1.22:1
Minimum tangible adjusted net worth	$	26,000	$	27,038

We met our quarterly financial covenants in the first quarter of 2018 and we expect to meet these quarterly financial covenant requirements in the next twelve months. If we fail to meet any of these quarterly financial covenant requirements as noted above and our lender does not waive the non-compliance or revise our covenant so that we are in compliance, our lender could accelerate the repayment of borrowings under our credit facility. In the event that our lender accelerates the payment of our borrowings, we may not have sufficient liquidity to repay our debt under our credit facility and other indebtedness.

M&EC Series B Preferred Stock

On April 24, 2018, the Company announced a private exchange offer (“Exchange Offer”), to all holders of the M&EC Series B Preferred Stock, to exchange, for every share of Series B Preferred Stock tendered, (a) 0.1050805 shares of newly issued common stock of the Company, par value $.001 per share (“Common Stock”), and (b) cash in lieu of fractional shares of Common Stock that would otherwise be issuable to the tendering holder of Series B Preferred Stock, in an amount equal to such fractional share of Common Stock multiplied by the closing price per share of the Common Stock on the last trading day immediately preceding the expiration date of the Exchange Offer. The Exchange Offer is being made on an all-or-none basis, for all 1,284,730 shares of Series B Preferred Stock outstanding and has an expiration date of May 30, 2018. Assuming all currently outstanding shares of Series B Preferred Stock are tendered for exchange and not validly withdrawn, the Company would issue an amount of its shares of Common Stock not to exceed 135,000. The Company owns 100% of the voting capital stock of M&EC. If the Exchange Offer is consummated, the holders of the M&EC Series B Preferred Stock would forfeit all rights of a holder of Series B Preferred Shares, including the right to receive quarterly cash dividends and the rights to the accrued and unpaid cumulative dividends on the M&EC Series B Preferred Stock, which the Company has accrued since the issuance of the Series B Preferred Stock in the amount of approximately $1,011,000 as of April 1, 2018. Although dividends on the M&EC Series B Preferred Stock are cumulative, such dividends are payable if, when, and as declared by the Board of M&EC. M&EC Board has never declared dividends on the Series B Preferred Stock and our credit facility prohibits the payment of cash dividends without our lender’s consent.

The shares of Company common stock to be issued in exchange for shares of M&EC’s Series B Preferred Stock will be issued pursuant to an exemption from registration under the Securities Act of 1933, as amended, and, as a result, will be considered restricted securities that have restrictions on transferability.

The above paragraphs as to the exchange offer do not constitute an offer or an invitation by us to participate in the exchange offer in any manner.

Off Balance Sheet Arrangements

From time to time, we are required to post standby letters of credit and various bonds to support contractual obligations to customers and other obligations, including facility closures. At March 31, 2018, the total amount of standby letters of credit outstanding totaled approximately $2,660,000 and the total amount of bonds outstanding totaled approximately $8,767,000. We also provide closure and post-closure requirements through a financial assurance policy for certain of our Treatment Segment facilities through AIG. At March 31, 2018, the closure and post-closure requirements for these facilities were approximately $29,911,000.

Critical Accounting Policies and Estimates

We adopted Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers” followed by a series of related accounting standard updates (collectively referred to as “Topic 606”) effective January 1, 2018. The adoption of Topic 606 did not materially impact our revenue recognition model. There were no significant changes in our accounting policies or critical accounting estimates that are discussed in our Annual Report on Form 10-K for the year ended December 31, 2017.

29

Known Trends and Uncertainties

Significant Customers. Our Treatment and Services Segments have significant relationships with the U.S federal government, and continue to enter into contracts, directly as the prime contractor or indirectly for others as a subcontractor, with the federal government. The U.S Department of Energy (“DOE”) and U.S. Department of Defense (“DOD”) represent major customers for our Treatment Segment and Services Segments. The contracts that we are a party to with the federal government or with others as a subcontractor to the federal government generally provide that the government may terminate or renegotiate the contracts on 30 days notice, at the government’s election. Our inability to continue under existing contracts that we have with the federal government (directly or indirectly as a subcontractor) or significant reductions in the level of governmental funding in any given year could have a material adverse impact on our operations and financial condition.

We performed services relating to waste generated by government clients (includes U.S federal and state), either directly as a prime contractor or indirectly for others as a subcontractor to government entities, representing approximately $9,654,000 or 76.3% of our total revenue during the three months ended March 31, 2018, as compared to $9,439,000 or 74.3% of our total revenue during the corresponding period of 2017.

Environmental Contingencies

We are engaged in the waste management services segment of the pollution control industry. As a participant in the on-site treatment, storage and disposal market and the off-site treatment and services market, we are subject to rigorous federal, state and local regulations. These regulations mandate strict compliance and therefore are a cost and concern to us. Because of their integral role in providing quality environmental services, we make every reasonable attempt to maintain complete compliance with these regulations; however, even with a diligent commitment, we, along with many of our competitors, may be required to pay fines for violations or investigate and potentially remediate our waste management facilities.

We routinely use third party disposal companies, who ultimately destroy or secure landfill residual materials generated at our facilities or at a client’s site. In the past, numerous third party disposal sites have improperly managed waste and consequently require remedial action; consequently, any party utilizing these sites may be liable for some or all of the remedial costs. Despite our aggressive compliance and auditing procedures for disposal of wastes, we could further be notified, in the future, that we are a potentially responsible party (“PRP”) at a remedial action site, which could have a material adverse effect.

Our subsidiaries where remediation expenditures will be made are at three sites within our discontinued operations. While no assurances can be made that we will be able to do so, we expect to fund the expenses to remediate these sites from funds generated from operations.

At March 31, 2018, we had total accrued environmental remediation liabilities of $848,000, of which $619,000 is recorded as a current liability, which reflects a decrease of $23,000 from the December 31, 2017 balance of $871,000. The decrease of $23,000 represents payments on remediation projects at our Perma-Fix of Dayton, Inc. subsidiary.

Item 3. Quantitative and Qualitative Disclosures about Market Risks

Not required for smaller reporting companies.

Item 4. Controls and Procedures

(a)	Evaluation of disclosure controls, and procedures.
	We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our periodic reports filed with the Securities and Exchange Commission is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission and that such information is accumulated and communicated to our management. As of the end of the period covered by this report, we carried out an evaluation with the participation of our Principal Executive Officer and Principal Financial Officer. Based on this recent assessment, our Principal Executive Officer and Principal Financial Officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended) were effective as of March 31, 2018.
(b)	Changes in internal control over financial reporting.
	Effective January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606) and a series of related accounting standard updates (collectively referred to as “Topic 606”). Although the adoption of the new revenue standards had no significant impact on our financial position, results of operations, or cash flows, we did implement changes to our controls related to revenue. These included the development of new policies and controls based on the five-step model provided in Topic 606, enhanced contract review requirements, and other ongoing monitoring activities. These controls were developed to provide assurance at a reasonable level for the fair presentation of our condensed consolidated financial statements and related disclosures. There was no other change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during our most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

1. Basis of Presentation

The consolidated condensed financial statements included herein have been prepared by the Company (which may be referred to as we, us or our), without an audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“the Commission”). Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations, although the Company believes the disclosures which are made are adequate to make the information presented not misleading. Further, the consolidated condensed financial statements reflect, in the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position and results of operations as of and for the periods indicated. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of results to be expected for the fiscal year ending December 31, 2018.

The Company suggests that these consolidated condensed financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Our accounting policies are as set forth in the notes to the December 31, 2017 consolidated financial statements referred to above.

Recently Adopted Accounting Standards

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers” followed by a series of related accounting standard updates (collectively referred to as “Topic 606”), which superseded nearly all existing revenue recognition guidance. Topic 606 provides a single, comprehensive revenue recognition model for all contracts with customers. Under the new standard, a five-step process is utilized in order to determine revenue recognition, depicting the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. Topic 606 also requires additional disclosure surrounding the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. Topic 606 is effective for annual reporting periods beginning after December 15, 2017 (including interim reporting periods within those periods). The new standard permits two implementation approaches: the full retrospective method, in which case the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. The Company adopted Topic 606 effective January 1, 2018 under the modified retrospective approach to all contracts as of date of adoption. The Company recognized the cumulative effect of initially adopting Topic 606 as an increase of approximately $317,000 to the opening balance of accumulated deficit at January 1, 2018. The adoption of Topic 606 did not result in significant changes to our revenue recognition model within our Treatment and Services Segments. The cumulative impact to the opening balance of accumulated deficit at January 1, 2018 was primarily driven by changes to the timing of revenue recognition in certain immaterial waste streams within our Treatment Segment. See “Note 3 – Revenue” for additional disclosures related to our revenues under the new standard. The comparative previous period information continues to be reported under the accounting standards in effect for that period. We expect the impact of the adoption of Topic 606 to be immaterial to our consolidated financial statements on an on-going basis.

The cumulative effect of the changes made to our January 1, 2018 unaudited Consolidated Balance Sheet for the adoption of Topic 606 was as follows (in thousands):

	Balance at			Adjustment			Opening balance at

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force),” which aims to eliminate diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other Topics. Subsequently, in November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230), Restricted Cash, a consensus of the FASB Emerging Issues Task Force,” which clarifies the guidance on the cash flow classification and presentation of changes in restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash or restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flow. ASU 2016-15 and ASU 2016-18 are effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017. The adoption of these ASUs by the Company effective January 1, 2018 did not have a material impact on the Company’s financial position, results of operations, or cash flows.

In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory,” which eliminates the existing exception in U.S. GAAP prohibiting the recognition of the income tax consequences for intra-entity asset transfers. Under ASU 2016-16, entities will be required to recognize the income tax consequences of intra-entity asset transfers other than inventory when the transfer occurs. ASU 2016-16 is effective on a modified retrospective basis for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The adoption of ASU 2016-16 by the Company effective January 1, 2018 did not have a material impact on the Company’s financial position, results of operations, or cash flows.

In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805) – Clarifying the Definition of a Business.” ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisition, disposals, goodwill and consolidation. This standard is effective for fiscal years beginning after December 15, 2017, including interim periods within that reporting period. The adoption of ASU 2017-01 by the Company effective January 1, 2018 did not have a material impact on the Company’s financial position, results of operations, or cash flows.

In May 2017, the FASB issued ASU 2017-09, “Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting.” This ASU provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU 2017-09 is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years, and early adoption is permitted, including in an interim period. ASU 2017-09 is to be applied on a prospective basis to an award modified on or after the adoption date. The adoption of ASU 2017-01 by the Company effective January 1, 2018 did not have a material impact on the Company’s financial position, results of operations, or cash flows.

Recently Issued Accounting Standards – Not Yet Adopted

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. This ASU is effective January 1, 2019 for the Company. The Company is still evaluating the potential impact of adopting this guidance on our financial statements.

In February 2018, FASB issued ASU 2018-02, “Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”. This ASU allows for the reclassification of certain income tax effects related to the Tax Cuts and Jobs Act between “Accumulated other comprehensive income” and “Retained earnings.” This ASU relates to the requirement that adjustments to deferred tax liabilities and assets related to a change in tax laws or rates to be included in “Income from continuing operations”, even in situations where the related items were originally recognized in “Other comprehensive income” (rather than in “Income from continuing operations”). ASU 2018-02 is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. Adoption of this ASU is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the tax laws or rates were recognized. The Company is currently assessing the impact that this standard will have on its financial statements.

Revenue from Contract with Customer [Abstract]

Revenue

3. Revenue

The Company accounts for revenue in accordance with ASC Topic 606, which we adopted on January 1, 2018 using the modified retrospective method. The majority of our revenue is derived from short term contracts with an original expected length of one year or less.

Performance Obligation

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue as the performance obligation is satisfied.

Treatment Segment Revenues:

Contracts in our Treatment Segment have a single performance obligation as the promise to receive, treat and dispose of waste is not separately identifiable in the contract and, therefore, not distinct. Performance obligations are generally satisfied over time using the input method. Under the input method, the Company uses a measure of progress divided into major phases which include receipt, treatment/processing and shipment/final disposal. As major processing phases are completed and the costs are incurred, the proportional percentage of revenue is recognized. Transaction price for Treatment Segment contracts are determined by the stated fixed rate per unit price as stipulated in the contract.

Services Segment Revenues:

Revenues for our Services Segment are generated from time and materials, cost reimbursement or fixed price arrangements:

The Company’s primary obligation to customers in time and materials contracts relate to the provision of services to the customer at the direction of the customer. This provision of services at the request of the customer is the performance obligation, which is satisfied over time. Revenue earned from time and materials contracts is determined using the input method and is based on contractually defined billing rates applied to services performed and materials delivered.

The Company’s primary performance obligation to customers in cost reimbursement contracts is to complete certain tasks and work steams. Each specified work stream or task within the contract is considered to be a separate performance obligation. The transaction price is calculated using an estimated cost to complete the various scope items to achieve the performance obligation as stipulated in the contract. An estimate is prepared for each individual scope item in the contract and the transaction price is allocated on a time and materials basis as services are provided. Revenue from cost reimbursement contracts is recognized over time using the input method based on costs incurred, plus a proportionate amount of fee earned.

Under fixed price contracts, the objective of the project is not attained unless all scope items within the contract are completed and all of the services promised within fixed fee contracts constitute a single performance obligation. Transaction price is estimated based upon the estimated cost to complete the overall project. Revenue from fixed price contract is recognized over time using the output method based on the percentage of project completion multiplied by the total fee as a measure of progress.

The nature of our contracts does not give rise to variable considerations.

Significant Payment Terms

Invoicing is based on schedules established in customer contracts. Payment terms vary by customers but are generally established at 30 days from invoicing.

Disaggregation of Revenue

In general, the Company’s business segmentation is aligned according to the nature and economic characteristics of our services and provides meaningful disaggregation of each business segment’s results of operations. The following tables present further disaggregation of our revenues by different categories for our Services and Treatment Segments:

	Three Months Ended						Three Months Ended

Contract Balances

The timing of revenue recognition, billings, and cash collections results in accounts receivable and unbilled receivables (contract assets). The Company’s contract liabilities consist of deferred revenues which represents advance payment from customers in advance of the completion of our performance obligation.

The following table represents changes in our contract assets and contract liabilities balances:

(In thousands)	March 31, 2018		January 1, 2018		Year-to-date Change ($)			Year-to-date Change (%)
Contract assets
Account receivables, net of allowance	$	4,762	$	7,940	$	(3,178	)		(40.0	)%
Unbilled receivables - current		4,574		4,547		27			0.6	%
Unbilled receivables - non-current		92		184		(92	)		(50.0	)%
Contract liabilities
Deferred revenue	$	4,620	$	5,083	$	(463	)		(9.1	)%

The net decrease in our contract assets was primarily due to increased accounts receivable collections. The Company provides various payment terms to our customers; therefore, our accounts receivable are impacted by these terms and the related timing of accounts receivable collections.

Revenue recognized for the three months ended March 31, 2018 and 2017 that was included in the contract liability balance at the beginning of each year was $3,811,000 and $2,977,000, respectively. All revenue recognized in each period related to performance obligations satisfied within the respective period.

Incremental Costs to Obtain a Contract

Costs incurred to obtain contracts with our customers are immaterial and as a result, the Company expenses (within selling, general and administration expenses (“SG&A”)) incremental costs incurred in obtaining contracts with our customer as incurred.

Remaining Performance Obligations

The Company applies the practical expedient in paragraph 606-10-50-14 and does not disclose information about remaining performance obligations that have original expected durations of one year or less.

The Company applies the transition practical expedient in paragraph 606-10-65-1(f)(3) and does not disclose the amount of the transaction price allocated to the remaining performance obligations or an explanation of when the Company expects to recognize that amount as revenue for periods prior to the adoption of Topic 606.

Capital Stock, Stock Plans and Stock-Based Compensation

5. Capital Stock, Stock Plans and Stock Based Compensation

The Company has certain stock option plans under which it awards incentive and non-qualified stock options to employees, officers, and outside directors.

On January 18, 2018, the Company granted 6,000 options from the Company’s 2003 Outside Directors Stock Plan to a new director elected by the Company’s Board of Directors (“Board”) to fill a vacancy on the Board. The options granted were for a contractual term of ten years with a vesting period of six months. The exercise price of the options was $4.05 per share, which was equal to our closing stock price the day preceding the grant date, pursuant to the 2003 Outside Directors Stock Plan.

On January 13, 2017, the Company granted 6,000 options from the Company’s 2003 Outside Directors Stock Plan to a new director elected by the Company’s Board to fill a vacancy left by Jack Lahav who retired from the Board in October 2016. The options granted were for a contractual term of ten years with a vesting period of six months. The exercise price of the options was $3.79 per share, which was equal to our closing stock price the day preceding the grant date, pursuant to the 2003 Outside Directors Stock Plan.

The Company estimates fair value of stock options using the Black-Scholes valuation model. Assumptions used to estimate the fair value of stock options granted include the exercise price of the award, the expected term, the expected volatility of the Company’s stock over the option’s expected term, the risk-free interest rate over the option’s expected term, and the expected annual dividend yield. The fair value of the options granted on January 18, 2018 and January 13, 2017 as discussed above and the related assumptions used in the Black-Scholes option model used to value the options granted were as follows:

	Outside Director Stock Options Granted
	January 18, 2018			January 13, 2017
Weighted-average fair value per option	$	2.55		$	2.63
Risk -free interest rate (1)		2.62	%		2.40	%
Expected volatility of stock (2)		57.29	%		56.32	%
Dividend yield		None			None
Expected option life (3)		10.0 years			10.0 years

(1)	The risk-free interest rate is based on the U.S. Treasury yield in effect at the grant date over the expected term of the option.
(2)	The expected volatility is based on historical volatility from our traded Common Stock over the expected term of the option.

Earnings Per Share [Abstract]

(Income) Loss Per Share

6. (Income) Loss Per Share

Basic income (loss) per share is calculated based on the weighted-average number of outstanding common shares during the applicable period. Diluted income (loss) per share is based on the weighted-average number of outstanding common shares plus the weighted-average number of potential outstanding common shares. In periods where they are anti-dilutive, such amounts are excluded from the calculations of dilutive earnings per shares. The following table reconciles the income (loss) and average share amounts used to compute both basic and diluted income (loss) per share:

Revolving Credit and Term Loan Agreement

The Company entered into an Amended and Restated Revolving Credit, Term Loan and Security Agreement, dated October 31, 2011 (“Amended Loan Agreement”), with PNC National Association (“PNC”), acting as agent and lender. The Amended Loan Agreement has been amended from time to time since the execution of the Amended Loan Agreement. The Amended Loan Agreement, as subsequently amended (“Revised Loan Agreement”), provides the Company with the following credit facility with a maturity date of March 24, 2021: (a) up to $12,000,000 revolving credit (“revolving credit”) and (b) a term loan (“term loan”) of approximately $6,100,000, which requires monthly installments of approximately $101,600 (based on a seven-year amortization). The maximum that we can borrow under the revolving credit is based on a percentage of eligible receivables (as defined) at any one time reduced by outstanding standby letters of credit and borrowing reductions that our lender may impose from time to time.

Under the Revised Loan Agreement, we have the option of paying an annual rate of interest due on the revolving credit at prime plus 2% or London Inter Bank Offer Rate (“LIBOR”) plus 3% and the term loan at prime plus 2.5% or LIBOR plus 3.5%.

Pursuant to the Revised Loan Agreement, the Company may terminate the Revised Loan Agreement, upon 90 days’ prior written notice upon payment in full of its obligations under the Revised Loan Agreement. The Company agreed to pay PNC 1.0% of the total financing had the Company paid off its obligations on or before March 23, 2017, .50% of the total financing had the Company paid off its obligations after March 23, 2017 but prior to or on March 23, 2018, and .25% of the total financing if the Company pays off its obligations after March 23, 2018 but prior to or on March 23, 2019. No early termination fee shall apply if the Company pays off its obligations after March 23, 2019.

At March 31, 2018, the borrowing availability under our revolving credit was approximately $2,823,000, based on our eligible receivables and includes an indefinite reduction of borrowing availability of $2,000,000 that the Company’s lender has imposed. Our borrowing availability under our revolving credit was also reduced by outstanding standby letters of credit totaling approximately $2,660,000.

The Company’s credit facility with PNC contains certain financial covenants, along with customary representations and warranties. A breach of any of these financial covenants, unless waived by PNC, could result in a default under our credit facility allowing our lender to immediately require the repayment of all outstanding debt under our credit facility and terminate all commitments to extend further credit. The Company met its quarterly financial covenants in the first quarter of 2018 and expects to meet its quarterly financial covenants in each of the remaining quarters of 2018 and into the first half of 2019.

M&EC Series B Preferred Stock

The Series B Preferred Stock (the “Series B Preferred Stock”) of the Company’s consolidated subsidiary, M&EC, is non-voting and non-convertible, has a $1.00 liquidation preference per share and may be redeemed at the option and sole discretion of M&EC at any time, and from time to time, from and after one year from the date of issuance of the Series B Preferred Stock for the purchase price of $1.00. Holders of shares of M&EC Series B Preferred Stock are entitled to receive, when, as and if declared by M&EC’s board of directors out of funds legally available for payment, cumulative dividends at the rate per annum of 5% per share on the liquidation preference of $1.00 per share of Series B Preferred Stock. Dividends on the Series B Preferred Stock shall accrue without interest beginning one year from the date of original issuance (June 25, 2001), and shall be payable in cash, if, when, and as declared by M&EC board, quarterly each year commencing on the first dividend due date following the expiration of one year from the date of original issuance. On April 24, 2018, the Company announced a private exchange offer (“Exchange Offer”), to all holders of the M&EC Series B Preferred Stock , to exchange, for every share of Series B Preferred Stock tendered, (a) 0.1050805 shares of newly issued common stock of the Company, par value $.001 per share (“Common Stock”), and (b) cash in lieu of fractional shares of Common Stock that would otherwise be issuable to the tendering holder of Series B Preferred Stock, in an amount equal to such fractional share of Common Stock multiplied by the closing price per share of the Common Stock on the last trading day immediately preceding the expiration date of the Exchange Offer. The Exchange Offer is being made on an all-or-none basis, for all 1,284,730 shares of Series B Preferred Stock outstanding and has an expiration date of May 30, 2018. Assuming all currently outstanding shares of Series B Preferred Stock are tendered for exchange and not validly withdrawn, the Company would issue an amount of its shares of Common Stock not to exceed 135,000. The Company owns 100% of the voting capital stock of M&EC. If the Exchange Offer is consummated, holders of the M&EC Series B Preferred Stock would forfeit all rights of a holder of Series B Preferred Shares, including the right to receive quarterly cash dividends, and the rights to the cumulative accrued and unpaid dividends with M&EC Series B Preferred Stock in the amount of approximately $1,011,000 as of April 1, 2018. M&EC Board has never declared dividends on the Series B Preferred Stock and our credit facility prohibits the payment of cash dividends without the lender’s consent.

The shares of Company common stock to be issued in exchange for shares of M&EC’s Series B Preferred Stock will be issued pursuant to an exemption from registration under the Securities Act of 1933, as amended, and, as a result, will be considered restricted securities that have restrictions on transferability.

This discussion as to an exchange offer does not constitute an offer or an invitation by the Company to participate in the exchange offer in any manner.

Accounting Policies [Abstract]

Recently Adopted Accounting Standards

Recently Adopted Accounting Standards

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers” followed by a series of related accounting standard updates (collectively referred to as “Topic 606”), which superseded nearly all existing revenue recognition guidance. Topic 606 provides a single, comprehensive revenue recognition model for all contracts with customers. Under the new standard, a five-step process is utilized in order to determine revenue recognition, depicting the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. Topic 606 also requires additional disclosure surrounding the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. Topic 606 is effective for annual reporting periods beginning after December 15, 2017 (including interim reporting periods within those periods). The new standard permits two implementation approaches: the full retrospective method, in which case the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. The Company adopted Topic 606 effective January 1, 2018 under the modified retrospective approach to all contracts as of date of adoption. The Company recognized the cumulative effect of initially adopting Topic 606 as an increase of approximately $317,000 to the opening balance of accumulated deficit at January 1, 2018. The adoption of Topic 606 did not result in significant changes to our revenue recognition model within our Treatment and Services Segments. The cumulative impact to the opening balance of accumulated deficit at January 1, 2018 was primarily driven by changes to the timing of revenue recognition in certain immaterial waste streams within our Treatment Segment. See “Note 3 – Revenue” for additional disclosures related to our revenues under the new standard. The comparative previous period information continues to be reported under the accounting standards in effect for that period. We expect the impact of the adoption of Topic 606 to be immaterial to our consolidated financial statements on an on-going basis.

The cumulative effect of the changes made to our January 1, 2018 unaudited Consolidated Balance Sheet for the adoption of Topic 606 was as follows (in thousands):

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force),” which aims to eliminate diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other Topics. Subsequently, in November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230), Restricted Cash, a consensus of the FASB Emerging Issues Task Force,” which clarifies the guidance on the cash flow classification and presentation of changes in restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash or restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flow. ASU 2016-15 and ASU 2016-18 are effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017. The adoption of these ASUs by the Company effective January 1, 2018 did not have a material impact on the Company’s financial position, results of operations, or cash flows.

In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory,” which eliminates the existing exception in U.S. GAAP prohibiting the recognition of the income tax consequences for intra-entity asset transfers. Under ASU 2016-16, entities will be required to recognize the income tax consequences of intra-entity asset transfers other than inventory when the transfer occurs. ASU 2016-16 is effective on a modified retrospective basis for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The adoption of ASU 2016-16 by the Company effective January 1, 2018 did not have a material impact on the Company’s financial position, results of operations, or cash flows.

In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805) – Clarifying the Definition of a Business.” ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisition, disposals, goodwill and consolidation. This standard is effective for fiscal years beginning after December 15, 2017, including interim periods within that reporting period. The adoption of ASU 2017-01 by the Company effective January 1, 2018 did not have a material impact on the Company’s financial position, results of operations, or cash flows.

In May 2017, the FASB issued ASU 2017-09, “Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting.” This ASU provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU 2017-09 is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years, and early adoption is permitted, including in an interim period. ASU 2017-09 is to be applied on a prospective basis to an award modified on or after the adoption date. The adoption of ASU 2017-01 by the Company effective January 1, 2018 did not have a material impact on the Company’s financial position, results of operations, or cash flows.

Recently Issued Accounting Standards – Not Yet Adopted

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. This ASU is effective January 1, 2019 for the Company. The Company is still evaluating the potential impact of adopting this guidance on our financial statements.

In February 2018, FASB issued ASU 2018-02, “Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”. This ASU allows for the reclassification of certain income tax effects related to the Tax Cuts and Jobs Act between “Accumulated other comprehensive income” and “Retained earnings.” This ASU relates to the requirement that adjustments to deferred tax liabilities and assets related to a change in tax laws or rates to be included in “Income from continuing operations”, even in situations where the related items were originally recognized in “Other comprehensive income” (rather than in “Income from continuing operations”). ASU 2018-02 is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. Adoption of this ASU is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the tax laws or rates were recognized. The Company is currently assessing the impact that this standard will have on its financial statements.
