Notes to the Consolidated Financial Statements

Note 1 - Summary of Significant Accounting Policies

Business

Hudson Technologies, Inc., incorporated under the laws of New York on January 11, 1991, is a refrigerant services company providing innovative solutions to recurring problems within the refrigeration industry. The Company’s operations consist of one reportable segment. The Company's products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems, and include refrigerant and industrial gas sales, refrigerant management services consisting primarily of reclamation of refrigerants and RefrigerantSide® Services performed at a customer's site, consisting of system decontamination to remove moisture, oils and other contaminants. In addition, the Company’s SmartEnergy OPS® service is a web-based real time continuous monitoring service applicable to a facility’s refrigeration systems and other energy systems. The Company’s Chiller Chemistry® and Chill Smart® services are also predictive and diagnostic service offerings. As a component of the Company’s products and services, the Company also generates carbon offset projects. The Company operates principally through its wholly-owned subsidiaries, Hudson Technologies Company and Aspen Refrigerants, Inc. Unless the context requires otherwise, references to the “Company”, “Hudson”, “we", “us”, “our”, or similar pronouns refer to Hudson Technologies, Inc. and its subsidiaries.

In preparing the accompanying consolidated financial statements, and in accordance with Accounting Standards Codification (ASC) 855-10 “Subsequent Events”, the Company’s management has evaluated subsequent events through the date that the financial statements were filed.

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial statements and with the instructions of Regulation S-X. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. The financial information included in this quarterly report should be read in conjunction with the Company’s audited financial statements and related notes thereto for the year ended December 31, 2018. Operating results for the nine month period ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.

In the opinion of management, all estimates and adjustments considered necessary for a fair presentation have been included and all such adjustments were normal and recurring.

Consolidation

The consolidated financial statements represent all companies of which Hudson directly or indirectly has majority ownership or otherwise controls. Significant intercompany accounts and transactions have been eliminated. The Company's consolidated financial statements include the accounts of wholly-owned subsidiaries Hudson Holdings, Inc., Hudson Technologies Company and Aspen Refrigerants, Inc. The Company does not present a statement of comprehensive income (loss) as its comprehensive income (loss) is the same as its net income (loss).

Going Concern

The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern and contemplate the realization of assets and satisfaction of liabilities in the normal course of business. The Company’s ability to continue as a going concern is contingent upon its ability to comply with the financial covenants within its credit agreements, referred to in Note 8. The Company’s level of indebtedness has adversely impacted, and continues to adversely impact, the Company’s financial condition, including operating results and liquidity position. As of June 30, 2019 and September 30, 2019, the Company was not in compliance with the financial covenants in the Term Loan Facility and the PNC Facility, thus raising substantial doubt as to the ability to continue as a going concern within one year after the date the financial statements were issued. The Company has satisfied all of its debt payment obligations on a timely basis and had over $14 million of cash on hand and $23 million of availability pursuant to the borrowing base formula in the PNC Facility as of September 30, 2019; and is working with its lenders to obtain a waiver and amendment of its credit facilities. However, there can be no assurance that the Company will be able to conclude any such waivers or amendments on acceptable terms or at all.

8

The accompanying consolidated financial statements do not include any adjustments related to the recoverability and classification of assets or the amounts and classifications of liabilities or any other adjustments that might be necessary should the Company be unable to continue as a going concern.

Fair Value of Financial Instruments

The carrying values of financial instruments including trade accounts receivable and accounts payable approximate fair value at September 30, 2019 and December 31, 2018, because of the relatively short maturity of these instruments. The carrying value of debt approximates fair value, due to the variable rate nature of the debt, as of September 30, 2019 and December 31, 2018.

Credit Risk

Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of temporary cash investments and trade accounts receivable. The Company maintains its temporary cash investments in highly-rated financial institutions and, at times, the balances exceed FDIC insurance coverage. The Company’s trade accounts receivable are primarily due from companies throughout the United States. The Company reviews each customer’s credit history before extending credit.

The Company establishes an allowance for doubtful accounts based on factors associated with the credit risk of specific accounts, historical trends, and other information. The carrying value of the Company’s accounts receivable is reduced by the established allowance for doubtful accounts. The allowance for doubtful accounts includes any accounts receivable balances that are determined to be uncollectible, along with a general reserve for the remaining accounts receivable balances. The Company adjusts its reserves based on factors that affect the collectability of the accounts receivable balances.

For the nine month period ended September 30, 2019, there was one customer accounting for 13% of the Company’s revenues. At September 30, 2019 there were $3.3 million of accounts receivable from this customer.

For the nine month period ended September 30, 2018, there were no customers that accounted for 10% or more of the Company’s revenues.

The loss of a principal customer or a decline in the economic prospects of and/or a reduction in purchases of the Company’s products or services by any such customer could have a material adverse effect on the Company’s operating results and financial position.

Cash and Cash Equivalents

Temporary investments with original maturities of ninety days or less are included in cash and cash equivalents.

Inventories

Inventories, consisting primarily of refrigerant products available for sale, are stated at the lower of cost, on a first-in first-out basis, or net realizable value. Where the market price of inventory is less than the related cost, the Company may be required to write down its inventory through a lower of cost or net realizable value adjustment, the impact of which would be reflected in cost of sales on the Consolidated Statements of Operations. Any such adjustment would be based on management’s judgment regarding future demand and market conditions and analysis of historical experience.

9

Property, Plant and Equipment

Property, plant and equipment are stated at cost, including internally manufactured equipment. The cost to complete equipment that is under construction is not considered to be material to the Company's financial position. Provision for depreciation is recorded (for financial reporting purposes) using the straight-line method over the useful lives of the respective assets. Leasehold improvements are amortized on a straight-line basis over the shorter of economic life or terms of the respective leases. Costs of maintenance and repairs are charged to expense when incurred.

Due to the specialized nature of the Company's business, it is possible that the Company's estimates of equipment useful life periods may change in the future.

Goodwill

The Company has made acquisitions that included a significant amount of goodwill and other intangible assets. The Company applies the purchase method of accounting for acquisitions, which among other things, requires the recognition of goodwill (which represents the excess of the purchase price of the acquisition over the fair value of the net assets acquired and identified intangible assets). We test our goodwill for impairment on an annual basis (the first day of the fourth quarter) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of an asset below its carrying value. Other intangible assets that meet certain criteria are amortized over their estimated useful lives.

Beginning in 2017, the Company adopted, on a prospective basis, ASU No. 2017-04, which simplifies the accounting for goodwill impairment by eliminating Step 2 of the prior goodwill impairment test that required a hypothetical purchase price allocation to measure goodwill impairment. Under the new standard, a company will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value.

An impairment charge would be recognized when the carrying amount exceeds the estimated fair value of a reporting unit. These impairment evaluations use many assumptions and estimates in determining an impairment loss, including certain assumptions and estimates related to future earnings. If the Company does not achieve its earnings objectives, the assumptions and estimates underlying these impairment evaluations could be adversely affected, which could result in an asset impairment charge that would negatively impact operating results. The Company’s performance has continued to be negatively impacted by the challenging pricing environment affecting the industry and the market during 2019 resulting in an increase in net realizable value adjustments for certain gases; however, the Company’s sales volume has increased in 2019 when compared to 2018. The Company determined as of September 30, 2019, that the year-to-date decline in revenue and operating loss, along with the decrease in the Company’s stock price during 2019 represented a triggering event which required a goodwill impairment test. Based on these indicators, the Company quantitatively evaluated its goodwill for impairment as of September 30, 2019 and determined that goodwill was not impaired.

Revenues and Cost of Sales

Beginning on January 1, 2018, the Company adopted, on a modified retrospective basis, Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers, which provides accounting guidance related to the recognition of revenue from contracts with customers. Based on the evaluation performed, the Company concluded that the adoption of this standard had no impact on its financial position, results of operations or cash flows and did not have a significant impact on its internal controls over financial reporting.

The Company’s products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems. Most of the Company’s revenues are realized from the sale of refrigerant and industrial gases and related products. The Company also generates revenue from refrigerant management services performed at a customer’s site and in-house. The Company conducts its business primarily within the US.

The Company applies the FASB’s guidance on revenue recognition, which requires the Company to recognize revenue in an amount that reflects the consideration the Company expects to be entitled in exchange for goods or services transferred to its customers. In most instances, the Company’s contract with a customer is the customer’s purchase order and the sales price to the customer is fixed. For certain customers, the Company may also enter into a sales agreement outlining a framework of terms and conditions applicable to future purchase orders received from that customer. Because the Company’s contracts with customers are typically for a single customer purchase order, the duration of the contract is usually less than one year. The Company’s performance obligations related to product sales are satisfied at a point in time, which may occur upon shipment of the product or receipt by the customer, depending on the terms of the arrangement. The Company’s performance obligations related to reclamation and RefrigerantSide® services are generally satisfied at a point in time when the service is performed. Accordingly revenues are recorded upon the shipment of the product, or in certain instances upon receipt by the customer, or the completion of the service.

10

In July 2016 the Company was awarded, as prime contractor, a five-year contract, including a five-year renewal option, by the United States Defense Logistics Agency (“DLA”) for the management, supply, and sale of refrigerants, compressed gases, cylinders and related services. Due to the contract containing multiple performance obligations, the Company assessed the arrangement in accordance with ASC 606. The Company determined that the sale of refrigerants and the management services provided under the contract each have stand-alone value. Accordingly, the performance obligations related to the sale of refrigerants is satisfied at a point in time, mainly when the customer receives and obtains control of the product. The performance obligation related to management service revenue is satisfied over time and revenue is recognized on a straight-line basis over the term of the arrangement as the management services are provided; such management fees are included in the below table as Product and related sales and were approximately $1.8 million for each of the nine months ended September 30, 2019 and 2018.

Cost of sales is recorded based on the cost of products shipped or services performed and related direct operating costs of the Company’s facilities. In general, the Company performs shipping and handling services for its customers in connection with the delivery of refrigerant and other products. In accordance with ASC 606-10-25-18B, the Company has elected to account for such shipping and handling as activities to fulfill the promise to transfer the good. To the extent that the Company charges its customers shipping fees, such amounts are included as a component of revenue and the corresponding costs are included as a component of cost of sales.

The Company’s revenues are derived from Product and related sales and RefrigerantSide® services revenues. The revenues for each of these lines are as follows:

	Three Months ended September 30,				Nine Months ended September 30,
	2019		2018		2019		2018
(in thousands)
Product and related sales	$	44,518	$	39,787	$	132,705	$	137,336
RefrigerantSide® services		1,113		758		3,601		3,468
Total	$	45,631	$	40,545	$	136,306	$	140,804

Income Taxes

The Company is taxed at statutory corporate income tax rates after adjusting income reported for financial statement purposes for certain items. Current income tax expense (benefit) reflects the tax results of revenues and expenses currently taxable or deductible. The Company utilizes the asset and liability method of accounting for deferred income taxes, which provides for the recognition of deferred tax assets or liabilities, based on enacted tax rates and laws, for the differences between the financial and income tax reporting bases of assets and liabilities.

The tax benefit associated with the Company’s net operating loss carry forwards (“NOLs”) is recognized to the extent that the Company expects to realize future taxable income. As a result of a prior “change in control”, as defined by the Internal Revenue Service, the Company’s ability to utilize its existing NOLs is subject to certain annual limitations. To the extent that the Company utilizes its NOLs, it will not pay tax on such income. However, to the extent that the Company’s net income, if any, exceeds the annual NOL limitation, it will pay income taxes based on the then existing statutory rates. In addition, certain states either do not allow or limit NOLs and as such the Company will be liable for certain state income taxes.

As of September 30, 2019, the Company had NOLs of approximately $39.1 million, of which $33.7 million have no expiration date (subject to annual limitations of 80% of tax earnings) and $5.4 million expire through 2023 (subject to annual limitations of approximately $1.3 million). As of September 30, 2019, the Company had state tax NOLs of approximately $20.0 million expiring in various years. We review the likelihood that we will realize the benefit of our deferred tax assets, and therefore the need for valuation allowances, on an annual basis in the fourth quarter of the year, and more frequently if events indicate that a review is required. In determining the requirement for a valuation allowance, the historical and projected financial results are considered, along with all other available positive and negative evidence.

Concluding that a valuation allowance is not required is difficult when there is significant negative evidence that is objective and verifiable, such as cumulative losses in recent years. We utilize a rolling twelve quarters of pre-tax income or loss adjusted for significant permanent book to tax differences, as well as non-recurring items, as a measure of our cumulative results in recent years. Based on the cumulative operating loss experienced through December 31, 2018, our analysis indicated that we had cumulative three year historical losses on this basis, which represented significant negative evidence that is objective and verifiable and, therefore, difficult to overcome. Based on our assessment as of December 31, 2018, we concluded that due to the uncertainty that the deferred tax assets will not be fully realized in the future, we recorded a valuation allowance of approximately $11.3 million during the year ended December 31, 2018 and increased the valuation allowance to $16.9 million as of September 30, 2019 due to additional losses.

As a result of an Internal Revenue Service audit, the 2013 and prior federal tax years have been closed. The Company operates in many states throughout the United States and, as of September 30, 2019, the various states’ statutes of limitations remain open for tax years subsequent to 2010.  The Company recognizes interest and penalties, if any, relating to income taxes as a component of the provision for income taxes.

The Company evaluates uncertain tax positions, if any, by determining if it is more likely than not to be sustained upon examination by the taxing authorities. As of September 30, 2019, and December 31, 2018, the Company believes it had no uncertain tax positions.

Income (Loss) per Common and Equivalent Shares

If dilutive, common equivalent shares (common shares assuming exercise of options) utilizing the treasury stock method are considered in the presentation of diluted loss per share. The reconciliation of shares used to determine net income (loss) per share is as follows (dollars in thousands, unaudited):

	Three Months ended September 30,					Nine Months ended September 30,
	2019		2018			2019			2018
Net income (loss)	$	2,667	$	(13,880	)	$	(15,169	)	$	(47,552	)
Weighted average number of shares – basic and diluted		42,618,391		42,530,476			42,608,396			42,445,926

During the three month periods ended September 30, 2019 and 2018, certain options aggregating 4,807,377 and 785,697 shares, respectively, have been excluded from the calculation of diluted shares, due to the fact that their effect would be anti-dilutive.

During the nine month periods ended September 30, 2019 and 2018, certain options aggregating 4,807,377 and 785,697 shares, respectively, have been excluded from the calculation of diluted shares, due to the fact that their effect would be anti-dilutive.

Estimates and Risks

The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the use of estimates and assumptions that affect the amounts reported in these financial statements and footnotes. The Company considers these accounting estimates to be critical in the preparation of the accompanying consolidated financial statements. The Company uses information available at the time the estimates are made. However, these estimates could change materially if different information or assumptions were used. Additionally, these estimates may not ultimately reflect the actual amounts of the final transactions that occur. The Company utilizes both internal and external sources to evaluate potential current and future liabilities for various commitments and contingencies. In the event that the assumptions or conditions change in the future, the estimates could differ from the original estimates.

12

Several of the Company's accounting policies involve significant judgments, uncertainties and estimates. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. To the extent that actual results differ from management's judgments and estimates, there could be a material adverse effect on the Company. On a continuous basis, the Company evaluates its estimates, including, but not limited to, those estimates related to its allowance for doubtful accounts, inventory reserves, and valuation allowance for the deferred tax assets relating to its NOLs and commitments and contingencies. With respect to accounts receivable, the Company estimates the necessary allowance for doubtful accounts based on both historical and anticipated trends of payment history and the ability of the customer to fulfill its obligations. For inventory, the Company evaluates both current and anticipated sales prices of its products to determine if a write down of inventory to net realizable value is necessary. In determining the Company’s valuation allowance for its deferred tax assets, the Company assesses its ability to generate taxable income in the future.

The Company participates in an industry that is highly regulated, and changes in the regulations affecting our business could affect our operating results. Currently the Company purchases virgin hydrochlorofluorocarbon (“HCFC”) and hydrofluorocarbon (“HFC”) refrigerants and reclaimable, primarily HCFC, HFC and chlorofluorocarbon (“CFC”), refrigerants from suppliers and its customers. Effective January 1, 1996, the Clean Air Act (the “Act”) prohibited the production of virgin CFC refrigerants and limited the production of virgin HCFC refrigerants. Effective January 2004, the Act further limited the production of virgin HCFC refrigerants and federal regulations were enacted which established production and consumption allowances for HCFC refrigerants which imposed limitations on the importation of certain virgin HCFC refrigerants. Under the Act, production of certain virgin HCFC refrigerants is scheduled to be phased out during the period 2010 through 2020, and production of all virgin HCFC refrigerants is scheduled to be phased out by 2030. In October 2014, the EPA published a final rule providing further reductions in the production and consumption allowances for virgin HCFC refrigerants for the years 2015 through 2019 (the “Final Rule”). In the Final Rule, the EPA established a linear draw down for the production or importation of virgin HCFC-22 that started at approximately 22 million pounds in 2015 and was reduced by approximately 4.5 million pounds each year ending at zero in 2020.

To the extent that the Company is unable to source sufficient quantities of refrigerants or is unable to obtain refrigerants on commercially reasonable terms or experiences a decline in demand and/or price for refrigerants sold by the Company, the Company could realize reductions in revenue from refrigerant sales, which could have a material adverse effect on its operating results and its financial position.

The Company is subject to various legal proceedings. The Company assesses the merit and potential liability associated with each of these proceedings. In addition, the Company estimates potential liability, if any, related to these matters. To the extent that these estimates are not accurate, or circumstances change in the future, the Company could realize liabilities, which could have a material adverse effect on its operating results and its financial position.

Impairment of Long-lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less the cost to sell.

Recent Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses." This ASU requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, and for interim periods therein. The Company does not expect the amended standard to have a material impact on the Company’s results of operations.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (ASU 2016-02), as amended, which generally requires lessees to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash flows arising from leasing arrangements. In July 2018, the FASB issued ASU No. 2018-11, Leases – Targeted Improvements, as an update to the previously-issued guidance. This update added a transition option which allows for the recognition of a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption without recasting the financial statements in periods prior to adoption. We have used the modified retrospective transition approach in ASU No. 2018-11 and applied the new lease requirements through a cumulative-effect adjustment in the period of adoption. We elected the package of practical expedients permitted under the transition guidance, which allows us to carryforward our historical lease classification, our assessment on whether a contract is or contains a lease, and our initial direct costs for any leases that existed prior to adoption of the new standard. We also elected to combine lease and non-lease components and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of operations on a straight-line basis over the lease term. We recorded approximately $8.1 million as total right-of-use assets and total lease liabilities on our consolidated balance sheet as of January 1, 2019. The Company’s accounting for finance leases remained substantially unchanged. Disclosures relating to the amount, timing and uncertainty of cash flows arising from leases are included in Note 5.

Note 2 - Fair Value

ASC Subtopic 820-10 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company often utilizes certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and/or the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market-corroborated, or generally unobservable inputs. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Based upon observable inputs used in the valuation techniques, the Company is required to provide information according to the fair value hierarchy.

The fair value hierarchy ranks the quality and reliability of the information used to determine fair values into three broad levels as follows: 

Level 1: Valuations for assets and liabilities traded in active markets from readily available pricing sources for market transactions involving identical assets or liabilities. 

Level 2: Valuations for assets and liabilities traded in less active dealer or broker markets.  Valuations are obtained from third-party pricing services for identical or similar assets or liabilities.

Level 3: Valuations for assets and liabilities include certain unobservable inputs in the assumptions and projections used in determining the fair value assigned to such assets or liabilities. 

In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

Note 5- Leases

The Company has various lease agreements with terms up to 11 years, including leases of buildings and various equipment. Some leases include options to purchase, terminate or extend for one or more years. These options are included in the lease term when it is reasonably certain that the option will be exercised.

At inception, the Company determines if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. Some of the Company’s lease arrangements contain lease components (e.g. minimum rent payments) and non-lease components (e.g. common area maintenance, charges, utilities and property taxes). The Company elected the package of practical expedients permitted under the transition guidance, which allows us to carry forward our historical lease classification, our assessment on whether a contract contains a lease, and our initial direct costs for any leases that existed prior to the adoption of the new standard. We also elected to combine lease and non-lease components and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of operations on a straight line basis over the lease term. The Company’s lease agreements do not contain any material residual value, guarantees or material restrictive covenants.

15

Operating leases are included in Right of use asset, Accrued expenses and other current liabilities, and Long-term lease liabilities on the consolidated balance sheets. These assets and liabilities are recognized at the commencement date based on the present value of remaining lease payments over the lease term using the Company’s secured incremental borrowing rates or implicit rates, when readily determinable. Short-term operating leases, which have an initial term of 12 months or less, are not recorded on the balance sheet. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Variable lease expense is recognized in the period in which the obligation for those payments is incurred. The Company has four leases with renewal options and they are not reasonably certain to be exercised.

Lease expense is included in selling, general and administrative expenses on the consolidated statements of operations and is reported net of lease income. Lease income is not material to the results of operations for the quarter and nine months ended September 30, 2019.

The following table presents information about the amount, timing and uncertainty of cash flows arising from the Company’s operating leases as of September 30, 2019.

Note 6 - Goodwill and intangible assets

Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in business combinations accounted for under the purchase method of accounting. In 2019, due to a significant selling price correction leading to unfavorable market conditions, the Company performed a quantitative test by weighting the results of an income-based valuation technique, the discounted cash flows method, and a market-based valuation technique to determine its reporting units’ fair values.

Based on the results of the impairment assessments of goodwill and other intangible assets performed in 2018, the Company concluded that it is more likely than not that the fair value of its goodwill exceeds the carrying value and that there are no impairment indicators related to intangible assets.

An impairment charge would be recognized when the carrying amount exceeds the estimated fair value of a reporting unit. These impairment evaluations use many assumptions and estimates in determining an impairment loss, including certain assumptions and estimates related to future earnings. If the Company does not achieve its earnings objectives, the assumptions and estimates underlying these impairment evaluations could be adversely affected, which could result in an asset impairment charge that would negatively impact operating results. The Company’s performance has continued to be negatively impacted by the challenging pricing environment affecting the industry and the market during 2019 resulting in an increase in inventory reserves for certain gases; however, the Company’s sales volume has increased in 2019 when compared to 2018. The Company determined as of September 30, 2019, that the year-to-date decline in revenue and operating loss, along with the decrease in the Company’s stock price during 2019 represented a triggering event which required a goodwill impairment test. Based on these indicators, the Company quantitatively evaluated its goodwill for impairment as of September 30, 2019 and determined that goodwill was not impaired.

At September 30, 2019 the Company had $47.8 million of goodwill, of which $47.0 million is attributable to the acquisition of Aspen Refrigerants, Inc. on October 10, 2017.

The Company’s other intangible assets consist of the following:

			September 30, 2019						December 31, 2018
	Amortization		Gross						Gross

17

Amortization expense for the nine months ended September 30, 2019 and 2018 was $2.2 million for both periods. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. During the third quarter of 2019, the Company recorded approximately $0.5 million of impairment charges associated with the shutdown of its Nashville and Puerto Rico facilities. No other impairment charges were recognized for the nine month period ended September 30, 2019 and for the year ended December 31, 2018.

Note 7 - Share-based compensation

Share-based compensation represents the cost related to share-based awards, typically stock options or stock grants, granted to employees, non-employees, officers and directors. Share-based compensation is measured at grant date, based on the estimated aggregate fair value of the award on the grant date, and such amount is charged to compensation expense on a straight-line basis (net of estimated forfeitures) over the requisite service period. For the nine month periods ended September 30, 2019 and 2018, share-based compensation expense of $0.9 million and $0.6 million, respectively, are reflected in general and administrative expenses in the consolidated Statements of Operations.

Share-based awards have historically been made as stock options, and recently also as stock grants, issued pursuant to the terms of the Company’s stock option and stock incentive plans, (collectively, the “Plans”), described below. The Plans may be administered by the Board of Directors or the Compensation Committee of the Board or by another committee appointed by the Board from among its members as provided in the Plans. Presently, the Plans are administered by the Company’s Compensation Committee of the Board of Directors. As of September 30, 2019, the Plans authorized the issuance of 7,000,000 shares of the Company’s common stock and, as of September 30, 2019 there were 2,717,400 shares of the Company’s common stock available for issuance for future stock option grants or other stock-based awards.

Stock option awards, which allow the recipient to purchase shares of the Company’s common stock at a fixed price, are typically granted at an exercise price equal to the Company’s stock price at the date of grant. Typically, the Company’s stock option awards have vested from immediately to two years from the grant date and have had a contractual term ranging from three to ten years.

Effective September 17, 2014, the Company adopted its 2014 Stock Incentive Plan (“2014 Plan”) pursuant to which 3,000,000 shares of common stock were reserved for issuance (i) upon the exercise of options, designated as either incentive stock options (“ISOs”) under the Internal Revenue Code of 1986, as amended (the “Code”) or nonqualified options, or (ii) as stock, deferred stock or other stock-based awards. ISOs may be granted under the 2014 Plan to employees and officers of the Company. Non-qualified options, stock, deferred stock or other stock-based awards may be granted to consultants, directors (whether or not they are employees), employees or officers of the Company. Stock appreciation rights may also be issued in tandem with stock options. Unless the 2014 Plan is sooner terminated, the ability to grant options or other awards under the 2014 Plan will expire on September 17, 2024.

ISOs granted under the 2014 Plan may not be granted at a price less than the fair market value of the common stock on the date of grant (or 110% of fair market value in the case of persons holding 10% or more of the voting stock of the Company). Nonqualified options granted under the 2014 Plan may not be granted at a price less than the fair market value of the common stock. Options granted under the 2014 Plan expire not more than ten years from the date of grant (five years in the case of ISOs granted to persons holding 10% or more of the voting stock of the Company). Certain options granted may contain a barrier price whereby the options are cancelled once the stock price declines below a predetermined barrier price for five consecutive trading days.

18

Effective June 7, 2018, the Company adopted its 2018 Stock Incentive Plan (“2018 Plan”) pursuant to which 4,000,000 shares of common stock were reserved for issuance (i) upon the exercise of options, designated as either ISOs under the Code or nonqualified options, or (ii) as stock, deferred stock or other stock-based awards. ISOs may be granted under the 2018 Plan to employees and officers of the Company. Non-qualified options, stock, deferred stock or other stock-based awards may be granted to consultants, directors (whether or not they are employees), employees or officers of the Company. Stock appreciation rights may also be issued in tandem with stock options. Unless the 2018 Plan is sooner terminated, the ability to grant options or other awards under the 2018 Plan will expire on June 7, 2028.

ISOs granted under the 2018 Plan may not be granted at a price less than the fair market value of the common stock on the date of grant (or 110% of fair market value in the case of persons holding 10% or more of the voting stock of the Company). Nonqualified options granted under the 2018 Plan may not be granted at a price less than the fair market value of the common stock. Options granted under the 2018 Plan expire not more than ten years from the date of grant (five years in the case of ISOs granted to persons holding 10% or more of the voting stock of the Company). Certain options granted may contain a barrier price whereby the options are cancelled once the stock price declines below a predetermined barrier price for five consecutive trading days.

All stock options have been granted to employees and non-employees at exercise prices equal to or in excess of the market value of the underlying common stock on the date of the grant. 

The Company determines the fair value of share-based awards at the grant date by using the Black-Scholes option-pricing model, and is incorporating the simplified method to compute expected lives of share-based awards. There were options to purchase 524,800 and 307,355 shares of common stock granted during the nine month periods ended September 30, 2019 and 2018, respectively.

A summary of the activity for stock options issued under the Company’s Plans for the indicated periods is presented below:

Stock Option Totals	Shares			Weighted Average Exercise Price
Outstanding at December 31, 2017		3,069,440		$	4.28
-Exercised		(5,000	)	$	3.43

The intrinsic value of options outstanding at September 30, 2019 and December 31, 2018 were $21,600 and $0, respectively.

The intrinsic value of options unvested at September 30, 2019 and December 31, 2018 were $0 and $0, respectively.

The intrinsic value of options exercised during the nine months ended September 30, 2019 and 2018 were $11,100 and $0, respectively.

As described in note 1, there is uncertainty around the Company’s ability to comply with current and future financial covenants. Therefore, in accordance with ASC 470, the Company has reclassified its term loan debt as a current liability as of September 30, 2019.

The Company was not in compliance with the Total Leverage Ratio and the minimum liquidity covenants, calculated as of June 30, 2019 and September 30, 2019, set forth in its Term Loan Facility. At September 30, 2019, the Company’s Total Leverage Ratio was 13.79:1.00 (versus a required Total Leverage Ratio of 6.40:1.00) and the Company’s Liquidity (as defined in the Term Loan Facility) was $23.2 million (versus a required level of $28 million). The Company was also not in compliance with the minimum EBITDA covenant for the four quarters ended June 30, 2019 set forth in the PNC Facility and the Fixed Charge Coverage Ratio (0.40 versus 1.00) covenant for the four quarters ended September 30, 2019 set forth in the PNC Facility.

Each of the foregoing represent an Event of Default, as defined in the respective loan agreements. The occurrence of an Event of Default under both the Term Loan Facility and the PNC Facility provide the respective lenders with the right to declare all amounts under the respective agreements to be immediately due and payable and the respective lenders have the right to terminate the obligation to make loans thereunder, and furthermore allows the respective lenders to exercise any and all other remedies under the applicable agreements. The lenders under both the Term Loan Facility and the PNC Facility have delivered reservation of rights letters and the Company has been making interest payments on the PNC Facility at the default rate of interest. The Company is currently seeking a waiver and amendment from its lenders to waive prior defaults and reset the financial covenants under both the Term Loan Facility and the PNC Facility. However, there can be no assurance that the Company will be able to conclude any such waivers or amendments on acceptable terms or at all.

(“ARI”), as borrowers (collectively, the “Borrowers”), and the Company as a guarantor, became obligated under an Amended and Restated Revolving Credit and Security Agreement (the “PNC Facility”) with PNC Bank, National Association, as administrative agent, collateral agent and lender (“Agent” or “PNC”), PNC Capital Markets LLC as lead arranger and sole bookrunner, and such other lenders as may thereafter become a party to the PNC Facility.

Under the terms of the PNC Facility, the Borrowers may borrow, from time to time, up to $150 million at any time consisting of revolving loans in a maximum amount up to the lesser of $150 million and a borrowing base that is calculated based on the outstanding amount of the Borrowers’ eligible receivables and eligible inventory, as described in the PNC Facility. The PNC Facility also contains a sublimit of $15 million for swing line loans and $5 million for letters of credit.

Amounts borrowed under the PNC Facility were used by the Borrowers to consummate the acquisition of ARI and for working capital needs, certain permitted future acquisitions, and to reimburse drawings under letters of credit. At September 30, 2019, total borrowings under the PNC Facility were $15.2 million, and total additional availability was approximately $23.2 million. In addition, there was a $130,000 outstanding letter of credit at September 30, 2019.

Interest on loans under the PNC Facility is payable in arrears on the first day of each month with respect to loans bearing interest at the domestic rate (as set forth in the PNC Facility) and at the end of each interest period with respect to loans bearing interest at the Eurodollar rate (as set forth in the PNC Facility) or, for Eurodollar rate loans with an interest period in excess of three months, at the earlier of (a) each three months from the commencement of such Eurodollar rate loan or (b) the end of the interest period. Interest charges with respect to loans were initially computed on the actual principal amount of loans outstanding during the month at a rate per annum equal to (A) with respect to domestic rate loans, the sum of (i) a rate per annum equal to the higher of (1) the base commercial lending rate of PNC, (2) the federal funds open rate plus 0.5% and (3) the daily LIBOR plus 1.0%, plus (ii) between 0.50% and 1.00% depending on average quarterly undrawn availability and (B) with respect to Eurodollar rate loans, the sum of the Eurodollar rate plus between 1.50% and 2.00% depending on average quarterly undrawn availability.

Borrowers and the Company granted to the Agent, for the benefit of the lenders, a security interest in substantially all of their respective assets, including receivables, equipment, general intangibles (including intellectual property), inventory, subsidiary stock, real property, and certain other assets.

The PNC Facility contains a financial covenant requiring the Company to maintain at all times a Fixed Charge Coverage Ratio (FCCR) of not less than 1.00 to 1.00, as of the end of each trailing period of four consecutive quarters. The FCCR (as defined in the PNC Facility) is the ratio of (a) EBITDA for such period, minus unfinanced capital expenditures made during such period, minus the aggregate amount of cash taxes paid during such period, to (b) the aggregate amount of all scheduled payments of principal (excluding principal payments relating to outstanding revolving loans under the PNC Facility) and all cash payments of interest, plus cash dividends and distributions made during such period, plus payments in respect of capital lease obligations made during such period.

On December 6, 2017, the Borrowers and the Company as a guarantor, entered into a First Amendment to Amended and Restated Revolving Credit and Security Agreement (the “First Revolver Amendment”) with PNC. The First Revolver Amendment, which was entered into in connection with the syndication of the credit facility, amended the PNC Facility to allow syndicate lenders to provide certain cash management and hedging products and services to the Borrowers, and made amendments to the PNC Facility with respect to lender approval requirements of specified matters and other administrative matters.

On November 30, 2018, the Borrowers and the Company as a guarantor, entered into a Second Amendment to Amended and Restated Revolving Credit and Security Agreement, Consent and Waiver (the “Second Revolver Amendment”) with PNC Bank, National Association, as administrative agent, collateral agent and lender and the lenders thereunder.

21

The Second Revolver Amendment amended the Amended and Restated Revolving Credit and Security Agreement dated October 10, 2017 (as amended to date, the “PNC Facility”), to replace the existing fixed charge coverage ratio until September 30, 2019 with an EBITDA covenant requiring minimum EBITDA for the four fiscal quarters ended on the following dates: September 30, 2018 - $9,240,000; December 31, 2018 - $9,428,000; March 31, 2019 - $9,270,000; June 30, 2019 - $14,195,000. The minimum fixed charge coverage ratio of 1.00:1.00 recommenced for the quarter ended September 30, 2019.

The Second Revolver Amendment also increased the applicable interest rate margin to 3% for Eurodollar Rate Loans (as defined in the PNC Facility) and 2% for Domestic Rate Loans (as defined in the PNC Facility) through September 30, 2019, with applicable margins thereafter of between 2.5% and 3% for Eurodollar Rate Loans and 1.5% and 2% for Domestic Rate Loans based on the applicable fixed charge coverage ratio. In connection with the Second Revolver Amendment, the Borrowers also paid the Agent a waiver and amendment fee of $250,000.

On April 17, 2019, the Borrowers, the Company as a guarantor, and ten new subsidiaries of the Borrowers (the “New Subsidiaries”), entered into a Third Amendment and Joinder to Amended and Restated Revolving Credit and Security Agreement and Waiver (the “Third Revolver Amendment”) with PNC Bank, National Association, as administrative agent, collateral agent and lender and the lenders thereunder. Pursuant to the Third Amendment, the New Subsidiaries were added as guarantors under the PNC Facility.

The Company evaluated the First, Second and Third Revolver Amendments in accordance with the provisions of ASC 470 to determine if the Amendments were a modification or an extinguishment of debt and concluded that amendments were a modification of the original term loan agreement for accounting purposes. As a result, the Company capitalized an additional $250,000 of deferred financing costs in connection with the Second Revolver Amendment, which are being amortized over the remaining term.

The PNC Facility also contains customary non-financial covenants relating to the Company and the Borrowers, including limitations on Borrowers’ ability to pay dividends on common stock or preferred stock, and also includes certain events of default, including payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to other obligations, events of bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of control.

The commitments under the PNC Facility will expire and the full outstanding principal amount of the loans, together with accrued and unpaid interest, are due and payable in full on October 10, 2022, unless the commitments are terminated and the outstanding principal amount of the loans are accelerated sooner following an event of default.

In connection with the closing of the PNC Facility, the Company also entered into an Amended and Restated Guaranty and Suretyship Agreement, dated as of October 10, 2017 (the “Revolver Guarantee”), pursuant to which the Company affirmed its unconditional guarantee of the payment and performance of all obligations owing by Borrowers to PNC, as Agent for the benefit of the revolving lenders.

Term Loan Facility

On October 10, 2017, HTC, Holdings, and ARI, as borrowers, and the Company, as guarantor, became obligated under a Term Loan Credit and Security Agreement (the “Term Loan Facility”) with U.S. Bank National Association, as administrative agent and collateral agent (“Term Loan Agent”) and funds advised by FS Investments and such other lenders as may thereafter become a party to the Term Loan Facility (the “Term Loan Lenders”).

Under the terms of the Term Loan Facility, the Borrowers immediately borrowed $105 million pursuant to a term loan (the “Initial Term Loan”) and could borrow up to an additional $25 million for a period of eighteen months after closing to fund additional permitted acquisitions (the “Delayed Draw Commitment”, and together with the Initial Term Loan, the “Term Loans”).

On June 29, 2018, HTC, Holdings and ARI, as borrowers, and the Company as a guarantor, entered into a Limited Waiver and First Amendment to Term Loan Credit and Security Agreement and Other Documents (the “First Amendment”) with U.S. Bank National Association, as collateral agent and administrative agent, and the various lenders thereunder. The First Amendment terminated the Delayed Draw Commitment and provided an interim waiver with respect to compliance with the existing total leverage ratio (“TLR”) covenant at June 30, 2018.

22

The Term Loans mature on October 10, 2023. Principal payments on the Term Loans are required on a quarterly basis, commencing with the quarter ended March 31, 2018, in the amount of 1% per annum of the original principal of the outstanding Term Loans. Commencing with the fiscal year ending December 31, 2018, the Term Loan Facility also requires annual principal payments of up to 50% of Excess Cash Flow (as defined in the Term Loan Facility) if the Company’s Total Leverage Ratio (as defined in the Term Loan Facility) for the applicable year is greater than 2.75 to 1.00. The Term Loan Facility also requires mandatory prepayments of the Term Loans in the event of certain asset dispositions, debt issuances, and casualty and condemnation events. The Term Loans may be prepaid at the option of the Borrowers at par in an amount up to $30 million. Additional prepayments are permitted after the first anniversary of the closing date and were originally subject to a prepayment premium of 3% in year two, 1% in year three and zero in year four and thereafter.

Interest on the Term Loans is generally payable on the earlier of the last day of the interest period applicable to such Eurodollar rate loan and the last day of the Term Loan Facility, as applicable. Interest was originally payable at the rate per annum of the Eurodollar Rate (as defined in the Term Loan Facility) plus 7.25%. The Borrowers have the option of paying 3.00% interest per annum in kind by adding such amount to the principal of the Term Loans during no more than five fiscal quarters during the term of the Term Loan Facility.

Borrowers and the Company granted to the Term Loan Agent, for the benefit of the Term Loan Lenders, a security interest in substantially all of their respective assets, including receivables, equipment, general intangibles (including intellectual property), inventory, subsidiary stock, real property, and certain other assets.

The Term Loan Facility originally contained a financial covenant requiring the Company to maintain a Total Leverage Ratio (TLR) of not greater than 4.75 to 1.00, tested as of the last day of the fiscal quarter. The Term Loan Facility was amended on August 14, 2018, including a waiver of the TLR covenant at June 30, 2018, as described below. The TLR (as defined in the Term Loan Facility) is the ratio of (a) funded debt as of such day to (b) EBITDA for the four consecutive fiscal quarters ending on the last day of such fiscal quarter. Funded debt (as defined in the Term Loan Facility) includes amounts borrowed under the PNC Facility and the Term Loan Facility as well as capitalized lease obligations and other indebtedness for borrowed money maturing more than one year from the date of creation thereof. As of September 30, 2019 and December 31, 2018, the TLR was approximately 13.79 to 1 and 11.82 to 1, respectively.

The Term Loan Facility also contains customary non-financial covenants relating to the Company and the Borrowers, including limitations on their ability to pay dividends on common stock or preferred stock, and also includes certain events of default, including payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to other obligations, events of bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of control.

In connection with the closing of the Term Loan Facility, the Company also entered into a Guaranty and Suretyship Agreement, dated as of October 10, 2017 (the “Term Loan Guarantee”), pursuant to which the Company affirmed its unconditional guarantee of the payment and performance of all obligations owing by Borrowers to Term Loan Agent, as agent for the benefit of the Term Loan Lenders.

The Term Loan Agent and the Agent have entered into an intercreditor agreement governing the relative priority of their security interests granted by the Borrowers and the Guarantor in the collateral, providing that the Agent shall have a first priority security interest in the accounts receivable, inventory, deposit accounts and certain other assets (the “Revolving Credit Priority Collateral”) and the Term Loan Agent shall have a first priority security interest in the equipment, real property, capital stock of subsidiaries and certain other assets (the “Term Loan Priority Collateral”).

On August 14, 2018, HTC, Holdings and ARI, as borrowers, and the Company as a guarantor, entered into a Waiver and Second Amendment to Term Loan Credit and Security Agreement (the “Second Amendment”) with U.S. Bank National Association, as collateral agent and administrative agent, and the various lenders thereunder. The Second Amendment superseded interim waivers and amended the Term Loan Facility, to waive compliance with the existing TLR covenant at June 30, 2018.

23

In addition, the Second Amendment also: (i) increases the interest rate by 300 basis points effective July 1, 2018; (ii) waives the existing prepayment premium in the Term Loan Facility in the event the term loan is repaid in full prior to March 31, 2020; (iii) adds an exit fee equal to three percent (3.00%) of the outstanding principal balance of the term loans on the date of the Second Amendment (provided, that payment of the exit fee is waived in the event that the term loan is repaid in full prior to January 1, 2020, and provided further that the exit fee is reduced to one-and-one-half percent (1.50%) in the event that the term loan is repaid in full on or after January 1, 2020 but prior to March 31, 2020); (iv) restricted acquisitions and other equity investments prior to September 30, 2018; and (v) required payment of a one-time waiver fee equal to one percent (1.00%) of the outstanding term loans.

On November 30, 2018, the Borrowers, and the Company as a guarantor, entered into a Waiver and Third Amendment to Term Loan Credit and Security Agreement (the “Third Amendment”) with U.S. Bank National Association, as collateral agent and administrative agent, and the various lenders thereunder.

The Third Amendment superseded interim waivers and amended the Term Loan Facility to reset the maximum Total Leverage Ratio covenant contained in the Term Loan Facility at the indicated dates as follows: (i) June 30, 2018 - 10.15:1.00; (ii) September 30, 2018 - 12.45:1.00; (iii) December 31, 2018 – 12.75:1.00; (iv) March 31, 2019 – 12.95:1.00; (v) June 30, 2019 – 8.25:1.00; September 30, 2019 – 6.40:1.00; (vi) December 31, 2019 – 5:70:1.00; and (vii) March 31, 2020 and each fiscal quarter thereafter – 4:75:1.00.

The Third Amendment increased the scheduled quarterly principal repayments to $525,000 effective December 31, 2018. In addition the Third Amendment requires a further repayment of principal on or before November 14, 2019 in an amount equal to (x) 100% of Excess Cash Flow (as defined in the Term Loan Facility) for the four fiscal quarter period ended September 30, 2019 if after giving effect to the payment thereof, the Borrowers have minimum aggregate Undrawn Availability (as defined in the Term Loan Facility) of at least $35,000,000, (y) 50% of Excess Cash Flow for the four fiscal quarter period ended September 30, 2019 if after giving effect to the payment thereof, the Borrowers have minimum aggregate Undrawn Availability of at least $15,000,000 but less than $35,000,000, and (z) 0% of Excess Cash Flow for the four fiscal quarter period ended September 30, 2019 if after giving effect to the payment thereof, the Borrowers have minimum aggregate Undrawn Availability less than $15,000,000, with any such payment subject to reduction by the amount of any voluntary prepayments made following the date of the Third Amendment. Any voluntary prepayments will not be subject to the prepayment premium or make-whole provisions of the Term Loan Facility. The Third Amendment also adds a minimum liquidity requirement (consisting of cash plus undrawn availability on the Borrowers’ revolving loan facility) of $28 million, measured monthly.

The Third Amendment also amended the exit fee payable to the term loan lenders to five percent (5.00%) of the outstanding principal balance of the term loans on November 30, 2018 (the “Exit Fee”), which Exit Fee shall be payable in full in cash upon the earlier to occur of (x) repayment in full of the term loans, or (y) any acceleration of the term loans. The Exit Fee will be reduced by one-tenth of one percent (0.10%) for every $1,000,000 in voluntary prepayments made prior to January 1, 2020; provided, that, in no event shall the Exit Fee be reduced below three percent (3.00%) as a result of any such prepayments, (ii) payment of the Exit Fee shall be waived in the event that repayment in full of the term loans occurs prior to January 1, 2020, and (iii) the Exit Fee shall be reduced by an amount equal to fifty percent (50%) of the amount that would otherwise payable in the event that repayment in full occurs on or after January 1, 2020 but prior to March 31, 2020.

On April 17, 2019, the Borrowers and the Company as a guarantor, and ten new subsidiaries of the Borrowers (the “New Subsidiaries”), entered into a Joinder to Term Loan Credit and Security Agreement and Other Documents (the “Joinder”) with U.S. Bank National Association, as collateral agent and administrative agent, and the various lenders thereunder. Pursuant to the Joinder, the New Subsidiaries were added as guarantors under the Term Loan Facility.

The Company evaluated the First, Second and Third Amendments in accordance with the provisions of ASC 470 to determine if the Amendments were a modification or an extinguishment of debt and concluded that the amendments were a modification of the original term loan agreement for accounting purposes. As a result, in 2018 the Company capitalized an additional $1.0 million of deferred financing costs in connection with the Second Amendment, which are being amortized over the remaining term.

24

Vehicle and Equipment Loans

The Company has entered into various vehicle and equipment loans. These loans are payable in 60 monthly payments through March 2020 and bear interest ranging from 0.0% to 8.3%.

Capital Lease Obligations

The Company rents certain equipment with a net book value of approximately $0.03 million at September 30, 2019 under leases which have been classified as capital leases. Scheduled future minimum lease payments under capital leases, net of interest, are as follows:

Twelve Month Period Ending September 30,	Amount
(in thousands)
-2020	$	14
-2021		5
-2022		0
-2023		0
-2024		0
Subtotal		19
Less interest expense		(1	)
Total	$	18

Scheduled maturities of the Company’s long-term debt and capital lease obligations are as follows:

Twelve Month Period Ending September 30,	Amount
(in thousands)
-2020	$	2,114
-2021		2,105
-2022		2,100
-2023		2,100
-2024		93,712
Total	$	102,131

The above schedule reflects the scheduled maturities related to the term loan, which has been reclassified to short-term due to the uncertainty around the Company’s ability to comply with current and future financial covenants.

Note 9 – Other income

In August 2019, the Company received $8.9 million of cash pursuant to the settlement of a working capital adjustment dispute arising from the acquisition of Aspen Refrigerants, Inc. in October 2017.

During the second quarter of 2019, the Company recorded approximately $0.5 million of other income relating to a change in estimate of its cylinder deposit liability account.

Item 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations

Certain statements, contained in this section and elsewhere in this Form 10-Q, constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements involve a number of known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. Such factors include, but are not limited to, changes in the laws and regulations affecting the industry, changes in the demand and price for refrigerants (including unfavorable market conditions adversely affecting the demand for, and the price of refrigerants), the Company’s ability to source refrigerants, regulatory and economic factors, seasonality, competition, litigation, the nature of supplier or customer arrangements that become available to the Company in the future, adverse weather conditions, possible technological obsolescence of existing products and services, possible reduction in the carrying value of long-lived assets, estimates of the useful life of its assets, potential environmental liability, customer concentration, the ability to obtain financing, the ability to meet financial covenants under our financing facilities, any delays or interruptions in bringing products and services to market, the timely availability of any requisite permits and authorizations from governmental entities and third parties as well as factors relating to doing business outside the United States, including changes in the laws, regulations, policies, and political, financial and economic conditions, including inflation, interest and currency exchange rates, of countries in which the Company may seek to conduct business, the Company’s ability to successfully integrate ARI and any other assets it acquires from third parties into its operations, and other risks detailed in the Company’s Form 10-K for the year ended December 31, 2018, and in the Company’s other subsequent filings with the Securities and Exchange Commission (“SEC”). The words “believe”, “expect”, “anticipate”, “may”, “plan”, “should” and similar expressions identify forward-looking statements. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date the statement was made.

Critical Accounting Policies

The Company's discussion and analysis of its financial condition and results of operations are based upon its consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these consolidated financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. Several of the Company's accounting policies involve significant judgments, uncertainties and estimates. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. To the extent that actual results differ from management's judgments and estimates, there could be a material adverse effect on the Company. On a continuous basis, the Company evaluates its estimates, including, but not limited to, those estimates related to its inventory reserves, and valuation allowance for the deferred tax assets relating to its net operating loss carry forwards (“NOLs”) and goodwill and intangible assets.

Inventory

For inventory, the Company evaluates both current and anticipated sales prices of its products to determine if a write down of inventory to net realizable value is necessary. Net realizable value represents the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion and disposal. The determination if a write-down to net realizable value is necessary is primarily affected by the market prices for the refrigerant gases we sell. Commodity prices generally are affected by a wide range of factors beyond our control, including weather, seasonality, the availability and adequacy of supply, government regulation and policies and general political and economic conditions. At any time, our inventory levels may be substantial.

Goodwill

The Company has made acquisitions that included a significant amount of goodwill and other intangible assets. The Company applies the purchase method of accounting for acquisitions, which among other things, requires the recognition of goodwill (which represents the excess of the purchase price of the acquisition over the fair value of the net assets acquired and identified intangible assets). We test our goodwill for impairment on an annual basis (the first day of the fourth quarter) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of an asset below its carrying value. Other intangible assets that meet certain criteria are amortized over their estimated useful lives.

26

Beginning in 2017, the Company adopted, on a prospective basis, ASU No. 2017-04, which simplifies the accounting for goodwill impairment by eliminating Step 2 of the prior goodwill impairment test that required a hypothetical purchase price allocation to measure goodwill impairment. Under the new standard, a company will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. An impairment charge would be recognized when the carrying amount exceeds the estimated fair value of a reporting unit. These impairment evaluations use many assumptions and estimates in determining an impairment loss, including certain assumptions and estimates related to future earnings. If the Company does not achieve its earnings objectives, the assumptions and estimates underlying these impairment evaluations could be adversely affected, which could result in an asset impairment charge that would negatively impact operating results.

During 2019 the Company’s performance has continued to be negatively impacted by the challenging pricing environment affecting the industry and the market during 2019. As a result, the Company performed a quantitative test at September 30, 2019 by weighing the results of an income-based valuation technique, the discounted cash flows method, and a market-based valuation technique to determine the fair value of its goodwill. The market approach was used as a test of reasonableness of the conclusions reached in the income approach. Under the income approach assumptions critical to our fair value estimates are: (i) discount rates used to derive the present value factors used in determining the fair value; (ii) projected revenue growth rates; and (iii) projected long-term growth rates used in the derivation of terminal year values. The market approach estimates fair value using comparable marketplace fair value data from within a comparable industry grouping. No impairment charges were recognized for the nine month period ended September 30, 2019 and for the year ended December 31, 2018.

Other Intangibles

Intangibles with determinable lives are amortized over the estimated useful lives of the assets currently ranging from 5 to 12 years. The Company reviews these useful lives annually to determine that they reflect future realizable value.

Income Taxes

As of September 30, 2019, the Company had NOLs of approximately $39.1 million, of which $33.7 million have no expiration date (subject to annual limitations of 80% of tax earnings) and $5.4 million expire through 2023 (subject to annual limitations of approximately $1.3 million). As of September 30, 2019, the Company had state tax NOLs of approximately $20.0 million expiring in various years. We review the likelihood that we will realize the benefit of our deferred tax assets, and therefore the need for valuation allowances, on an annual basis in the fourth quarter of the year, and more frequently if events indicate that a review is required. In determining the requirement for a valuation allowance, the historical and projected financial results are considered, along with all other available positive and negative evidence.

Concluding that a valuation allowance is not required is difficult when there is significant negative evidence that is objective and verifiable, such as cumulative losses in recent years. We utilize a rolling twelve quarters of pre-tax income or loss adjusted for significant permanent book to tax differences, as well as non-recurring items, as a measure of our cumulative results in recent years. Based on the cumulative operating loss experienced through December 31, 2018, our analysis indicated that we had cumulative three year historical losses on this basis, which represented significant negative evidence that is objective and verifiable and, therefore, difficult to overcome. Based on our assessment as of December 31, 2018, we concluded that due to the uncertainty that the deferred tax assets will not be fully realized in the future, we recorded a valuation allowance of approximately $11.3 million during the period ended December 31, 2018 and increased the valuation allowance to $16.9 million as of September 30, 2019 due to additional losses.

Overview

Sales of refrigerants continue to represent a significant majority of the Company’s revenues. The Company’s refrigerant sales are primarily HCFC and HFC based refrigerants and to a lesser extent CFC based refrigerants that are no longer manufactured. Currently, the Company purchases virgin HCFC and HFC refrigerants and reclaimable HCFC, HFC and CFC refrigerants from suppliers and its customers. Effective January 1, 1996, the Clean Air Act (the “Act”) prohibited the production of virgin CFC refrigerants and limited the production of virgin HCFC refrigerants, which production was further limited in January 2004. Federal regulations enacted in January 2004 established production and consumption allowances for HCFCs and imposed limitations on the importation of certain virgin HCFC refrigerants. Under the Act, production of certain virgin HCFC refrigerants is scheduled to be phased out during the period 2010 through 2020, and production of all virgin HCFC refrigerants is scheduled to be phased out by 2030. In October 2014, the EPA published the Final Rule providing further reductions in the production and consumption allowances for virgin HCFC refrigerants for the years 2015 through 2019. Effective January 1, 2020, there will be no more production or importation allowance for R-22.

The Company has created and developed a service offering known as RefrigerantSide® Services. RefrigerantSide® Services are sold to contractors and end-users whose refrigeration systems are used in commercial air conditioning and industrial processing. These services are offered in addition to refrigerant sales and the Company’s traditional refrigerant management services, which consist primarily of reclamation of refrigerants. The Company has created a network of service depots that provide a full range of the Company’s RefrigerantSide® Services to facilitate the growth and development of its service offerings.

The Company focuses its sales and marketing efforts for its RefrigerantSide® Services on customers who the Company believes most readily appreciate and understand the value that is provided by its RefrigerantSide® Services offering. In pursuing its sales and marketing strategy, the Company offers its RefrigerantSide® Services to customers in the following industries: petrochemical, pharmaceutical, industrial power, manufacturing, commercial facility and property management and maritime. The Company may incur additional expenses as it further develops and markets its RefrigerantSide® Services offering.

In July 2016 the Company was awarded, as prime contractor, a five-year contract, including a five-year renewal option, by the United States Defense Logistics Agency (“DLA”) for the management, supply, and sale of refrigerants, compressed gases, cylinders and related services.

Going Concern

Please refer to footnote 1 of the Company’s Consolidated Financial Statements.

28

The accompanying consolidated financial statements do not include any adjustments related to the recoverability and classification of assets or the amounts and classifications of liabilities or any other adjustments that might be necessary should the Company be unable to continue as a going concern.

Results of Operations

Three-month period ended September 30, 2019 as compared to the three-month period ended September 30, 2018

Revenues for the three-month period ended September 30, 2019 were $45.6 million, an increase of $5.1 million or 13% from the $40.5 million reported during the comparable 2018 period. The increase in revenues was due to an increase in refrigerant volumes and growth with the DLA contract offset by a decline in certain prices of refrigerants sold during the third quarter of 2019 quarter when compared to 2018.

Cost of sales for the three-month period ended September 30, 2019 was $37.8 million or 83% of sales. The cost of sales for the three-month period ended September 30, 2018 was $32.8 million or 81% of sales. The Company’s performance has been negatively impacted by the challenging pricing environment affecting the industry and the market during 2018 and 2019, leading to an increase in inventory reserves for certain gases. However, the Company has experienced higher volumes of refrigerant inventory sold during the third quarter of 2019 when compared to the third quarter of 2018.

Selling, general and administrative (“SG&A”) expenses for the three-month period ended September 30, 2019 were $8.3 million, an increase of $0.9 million from the $7.4 million reported during the comparable 2018 period. The increase in SG&A mainly relates to increased professional fees, stock compensation expense and insurance.

Amortization expense for both the three-month periods ended September 30, 2019 and 2018 was $0.7 million.

Other income for the three-month period ended September 30, 2019 was $4.5 million, compared to the $4.1 million of other expense reported during the comparable 2018 period. In August 2019, the Company recorded and received $8.9 million of cash pursuant to the settlement of a working capital adjustment dispute arising from the acquisition of Aspen Refrigerants, Inc. in October 2017. Interest expense was $4.4 million and $4.1 million during the three-month periods ended September 30, 2019 and 2018, respectively; the increase in interest expense mainly relates to an increase in interest rate margin (spread) as a result of the amendment of our credit facilities in November 2018.

The income tax expense for the three-month period ended September 30, 2019 was $0.5 million compared to $9.4 million for the three month period ended September 30, 2018. For 2019 and 2018, income tax expense for federal and state income tax purposes was determined by applying statutory income tax rates to pre-tax income after adjusting for certain items. As discussed previously, we concluded that due to the uncertainty that the deferred tax assets will not be fully realized in the future, we have recorded a full valuation allowance as of September 30, 2019; as such, the income tax expense recorded during the three-month period ended September 30, 2019 consists of a timing difference between book and tax reporting.

The net income for the three-month period ended September 30, 2019 was $2.7 million, an increase of $16.6 million from the $13.9 million of net loss reported during the comparable 2018 period, primarily due to Other income and lower tax expense, as described above.

Nine month period ended September 30, 2019 as compared to the Nine month period ended September 30, 2018

Revenues for the nine month period ended September 30, 2019 were $136.3 million, a decrease of $4.5 million or 3% from the $140.8 million reported during the comparable 2018 period. Refrigerant average selling prices declined by 16%, partially offset by a 4% increase in refrigerant volume. Revenue from the DLA also increased by approximately $5.5 million.

Cost of sales for the nine-month period ended September 30, 2019 was $123.9 million or 91% of sales. The cost of sales for the nine-month period ended September 30, 2018 was $151.3 million or 107% of sales. The Company recorded lower of cost or net realizable value adjustments to its inventory of $9.2 million and $34.7 million during the second quarter of 2019 and 2018, respectively. The $34.7 million adjustment recorded during the second quarter of 2018 included a $17.6 million write-down of a previously recorded step-up in inventory basis associated with the acquisition of ARI and a $17.1 million write-down for a lower of cost or net realizable value adjustment. The Company’s performance has been negatively impacted by the challenging pricing environment affecting the industry and the market during 2018 and 2019, leading to an increase in inventory reserves for certain gases. However, the Company has experienced higher volumes of refrigerant inventory sold during the nine months ended September 30, 2019 when compared to the comparable 2018 period, as described above.

29

Selling, general and administrative (“SG&A”) expenses for the nine-month period ended September 30, 2019 were $21.2 million, a decrease of $4.8 million from the $26.0 million reported during the comparable 2018 period. Professional fees pertaining to integration and related services relating to the acquisition of ARI declined by approximately $3.9 million. The remaining decrease in SG&A is primarily due to reduced payroll-related expenses, advertising and other professional fees in 2019.

Amortization expense for both the nine-month periods ended September 30, 2019 and 2018 was $2.2 million.

Other expense for the nine-month period ended September 30, 2019 was $3.5 million, compared to the $10.6 million of other expense reported during the comparable 2018 period. In August 2019, the Company recorded and received $8.9 million of cash pursuant to the settlement of a working capital adjustment dispute arising from the acquisition of Aspen Refrigerants, Inc. in October 2017. During the second quarter of 2019, the Company recorded approximately $0.5 million of other income relating to a change in estimate of its cylinder deposit liability account. Interest expense was $12.9 million and $10.6 million during the nine-month periods ended September 30, 2019 and 2018, respectively; the increase in interest expense mainly relates to an increase in interest rate margin (spread) as a result of the amendment of our credit facilities in November 2018.

The income tax expense for the nine-month period ended September 30, 2019 was $0.7 million compared to income tax benefit of $1.8 million for the nine month period ended September 30, 2018. For 2019 and 2018, income tax expense for federal and state income tax purposes was determined by applying statutory income tax rates to pre-tax income after adjusting for certain items. As discussed previously, we concluded that due to the uncertainty that the deferred tax assets will not be fully realized in the future, we have recorded a full valuation allowance as of September 30, 2019; as such, the income tax expense recorded during the nine-month period ended September 30, 2019 consists of a timing difference between book and tax reporting. 

The net loss for the nine-month period ended September 30, 2019 was $15.2 million, a decrease of $32.4 million from the $47.6 million of net loss reported during the comparable 2018 period, primarily due to reduced SG&A and inventory reserve adjustments, offset by lower tax benefits and higher interest expense.

Liquidity and Capital Resources

As described above, there is uncertainty around the Company’s ability to comply with current and future financial covenants under its credit agreements. Therefore, in accordance with ASC 470, the Company reclassified its term loan debt as a current liability as of June 30, 2019. The Company’s level of indebtedness has adversely impacted, and continues to adversely impact, the Company’s financial condition, including operating results and liquidity position. As of September 30, 2019, the Company was not in compliance with the financial covenants in the Term Loan Facility and the PNC Facility, thus raising substantial doubt as to the ability to continue as a going concern. The Company has satisfied all of its debt and other payment obligations on a timely basis, including payment of $15.9 million of debt during the nine months ended September 30, 2019. In addition, the Company had $14.7 million in cash and over $23 million of availability pursuant to the borrowing base formula in the PNC Facility as of September 30, 2019. As such, the Company does not believe that the covenant defaults relate to a liquidity issue, but a leverage issue with its current covenant structure and is working with its lenders to obtain a waiver and amendment of its credit facilities. However, there can be no assurance that the Company will be able to conclude any such waivers or amendments on acceptable terms or at all. At September 30, 2019, the Company had working capital, which represents current assets less current liabilities, of negative $45.1 million, which includes long-term debt re-classified as short-term, when compared to a positive $63.2 million at December 31, 2018. Excluding the reclassification of its term loan debt to short-term, the decrease in working capital is primarily attributable to timing factors related to the inventory and trade receivables as described below.

30

Inventory and trade receivables are principal components of current assets. At September 30, 2019, the Company had inventories of $59.4 million, a decrease of $42.6 million from $102.0 million at December 31, 2018. The decrease in the inventory balance is primarily due to the timing and availability of inventory purchases and the sale of refrigerants. The Company’s ability to sell and replace its inventory on a timely basis and the prices at which it can be sold are subject, among other things, to current market conditions and the nature of supplier or customer arrangements and the Company’s ability to source CFC based refrigerants (which are no longer being produced), HCFC refrigerants (which are currently being phased down leading to a full phase out of virgin production), or non-CFC based refrigerants. At September 30, 2019, the Company had trade receivables, net of allowance for doubtful accounts, of $19.8 million, an increase of $5.7 million from $14.1 million at December 31, 2018. The Company’s trade receivables are concentrated with various wholesalers, brokers, contractors and end-users within the refrigeration industry that are primarily located in the continental United States. The Company has historically financed its working capital requirements through cash flows from operations, the issuance of debt and equity securities, and bank borrowings.

Net cash provided by operating activities for the nine month period ended September 30, 2019 was $29.3 million, when compared to net cash provided by operating activities of $35.3 million for the comparable 2018 period. Net cash provided by operating activities in the 2019 period decreased due to the net loss reported in the period and timing of certain receivables and payables balances during the quarter.

Net cash used by investing activities for the nine month period ended September 30, 2019 was $0.9 million compared with net cash used in investing activities of $1.0 million for the comparable 2018 period. The Company’s capital investment spending in 2019 was consistent with 2018.

Net cash used in financing activities for the nine month period ended September 30, 2019 was $15.9 million compared with net cash used in financing activities of $37.9 million for the comparable 2018 period. During the nine-months ended September 30, 2019, the Company reduced its loan balance under the PNC Facility by $13.8 million versus $36.1 million of repayment in the comparable 2018 period. In 2018, the Company received a $10.3 million tax refund, which it utilized to pay down the PNC Facility.

At September 30, 2019, cash and cash equivalents were $14.7 million, or approximately $12.4 million higher than the $2.3 million of cash and cash equivalents at December 31, 2018. All excess cash is being utilized to pay down debt.

Credit Facilities

The Company was not in compliance with the Total Leverage Ratio and the minimum liquidity covenants, calculated as of June 30, 2019 and September 30, 2019, set forth in its Term Loan Facility. At September 30, 2019, the Company’s Total Leverage Ratio was 13.79:1.00 (versus a required Total Leverage Ratio of 6.40:1.00) and the Company’s Liquidity (as defined in the Term Loan Facility) was $23.2 million (versus a required level of $28 million). The Company was also not in compliance with the minimum EBITDA covenant for the four quarters ended June 30, 2019 set forth in the PNC Facility and the Fixed Charge Coverage Ratio (0.40 versus 1.00) covenant for the four quarters ended September 30, 2019 set forth in the PNC Facility.

Each of the foregoing represent an Event of Default, as defined in the respective loan agreements. The occurrence of an Event of Default under both the Term Loan Facility and the PNC Facility provide the respective lenders with the right to declare all amounts under the respective agreements to be immediately due and payable and the respective lenders have the right to terminate the obligation to make loans thereunder, and furthermore allows the respective lenders to exercise any and all other remedies under the applicable agreements. The lenders under both the Term Loan Facility and the PNC Facility have delivered reservation of rights letters and the Company has been making interest payments on the PNC Facility at the default rate of interest. The Company is currently seeking a waiver and amendment from its lenders to waive prior defaults and reset the financial covenants under both the Term Loan Facility and the PNC Facility. However, there can be no assurance that the Company will be able to conclude any such waivers or amendments on acceptable terms or at all.

Bank Credit Line

On October 10, 2017, Hudson Technologies Company (“HTC”), Hudson Holdings, Inc. (“Holdings”) and Aspen Refrigerants, Inc. (“ARI”), as borrowers (collectively, the “Borrowers”), and the Company as a guarantor, became obligated under an Amended and Restated Revolving Credit and Security Agreement (the “PNC Facility”) with PNC Bank, National Association, as administrative agent, collateral agent and lender (“Agent” or “PNC”), PNC Capital Markets LLC as lead arranger and sole bookrunner, and such other lenders as may thereafter become a party to the PNC Facility.

Under the terms of the PNC Facility, the Borrowers may borrow, from time to time, up to $150 million at any time consisting of revolving loans in a maximum amount up to the lesser of $150 million and a borrowing base that is calculated based on the outstanding amount of the Borrowers’ eligible receivables and eligible inventory, as described in the PNC Facility. The PNC Facility also contains a sublimit of $15 million for swing line loans and $5 million for letters of credit.

Amounts borrowed under the PNC Facility were used by the Borrowers to consummate the acquisition of ARI and for working capital needs, certain permitted future acquisitions, and to reimburse drawings under letters of credit. At September 30, 2019, total borrowings under the PNC Facility were $15.2 million, and total additional availability was approximately $23.2 million. In addition, there was a $130,000 outstanding letter of credit at September 30, 2019.

Interest on loans under the PNC Facility is payable in arrears on the first day of each month with respect to loans bearing interest at the domestic rate (as set forth in the PNC Facility) and at the end of each interest period with respect to loans bearing interest at the Eurodollar rate (as set forth in the PNC Facility) or, for Eurodollar rate loans with an interest period in excess of three months, at the earlier of (a) each three months from the commencement of such Eurodollar rate loan or (b) the end of the interest period. Interest charges with respect to loans were initially computed on the actual principal amount of loans outstanding during the month at a rate per annum equal to (A) with respect to domestic rate loans, the sum of (i) a rate per annum equal to the higher of (1) the base commercial lending rate of PNC, (2) the federal funds open rate plus 0.5% and (3) the daily LIBOR plus 1.0%, plus (ii) between 0.50% and 1.00% depending on average quarterly undrawn availability and (B) with respect to Eurodollar rate loans, the sum of the Eurodollar rate plus between 1.50% and 2.00% depending on average quarterly undrawn availability.

Borrowers and the Company granted to the Agent, for the benefit of the lenders, a security interest in substantially all of their respective assets, including receivables, equipment, general intangibles (including intellectual property), inventory, subsidiary stock, real property, and certain other assets.

The PNC Facility contains a financial covenant requiring the Company to maintain at all times a Fixed Charge Coverage Ratio (FCCR) of not less than 1.00 to 1.00, as of the end of each trailing period of four consecutive quarters. The FCCR (as defined in the PNC Facility) is the ratio of (a) EBITDA for such period, minus unfinanced capital expenditures made during such period, minus the aggregate amount of cash taxes paid during such period, to (b) the aggregate amount of all scheduled payments of principal (excluding principal payments relating to outstanding revolving loans under the PNC Facility) and all cash payments of interest, plus cash dividends and distributions made during such period, plus payments in respect of capital lease obligations made during such period.

On December 6, 2017, the Borrowers and the Company as a guarantor, entered into a First Amendment to Amended and Restated Revolving Credit and Security Agreement (the “First Revolver Amendment”) with PNC. The First Revolver Amendment, which was entered into in connection with the syndication of the credit facility, amended the PNC Facility to allow syndicate lenders to provide certain cash management and hedging products and services to the Borrowers, and made amendments to the PNC Facility with respect to lender approval requirements of specified matters and other administrative matters.

On November 30, 2018, the Borrowers and the Company as a guarantor, entered into a Second Amendment to Amended and Restated Revolving Credit and Security Agreement, Consent and Waiver (the “Second Revolver Amendment”) with PNC Bank, National Association, as administrative agent, collateral agent and lender and the lenders thereunder.

The Second Revolver Amendment amended the Amended and Restated Revolving Credit and Security Agreement dated October 10, 2017 (as amended to date, the “PNC Facility”), to replace the existing fixed charge coverage ratio until September 30, 2019 with an EBITDA covenant requiring minimum EBITDA for the four fiscal quarters ended on the following dates: September 30, 2018 - $9,240,000; December 31, 2018 - $9,428,000; March 31, 2019 - $9,270,000; June 30, 2019 - $14,195,000. The minimum fixed charge coverage ratio of 1.00:1.00 recommenced for the quarter ended September 30, 2019.

32

The Second Revolver Amendment also increased the applicable interest rate margin to 3% for Eurodollar Rate Loans (as defined in the PNC Facility) and 2% for Domestic Rate Loans (as defined in the PNC Facility) through September 30, 2019, with applicable margins thereafter of between 2.5% and 3% for Eurodollar Rate Loans and 1.5% and 2% for Domestic Rate Loans based on the applicable fixed charge coverage ratio. In connection with the Second Revolver Amendment, the Borrowers also paid the Agent a waiver and amendment fee of $250,000.

On April 17, 2019, the Borrowers, the Company as a guarantor, and ten new subsidiaries of the Borrowers (the “New Subsidiaries”), entered into a Third Amendment and Joinder to Amended and Restated Revolving Credit and Security Agreement and Waiver (the “Third Revolver Amendment”) with PNC Bank, National Association, as administrative agent, collateral agent and lender and the lenders thereunder. Pursuant to the Third Amendment, the New Subsidiaries were added as guarantors under the PNC Facility.

The Company evaluated the First, Second and Third Revolver Amendments in accordance with the provisions of ASC 470 to determine if the Amendments were a modification or an extinguishment of debt and concluded that amendments were a modification of the original term loan agreement for accounting purposes. As a result, the Company capitalized an additional $250,000 of deferred financing costs in connection with the Second Revolver Amendment, which are being amortized over the remaining term.

The PNC Facility also contains customary non-financial covenants relating to the Company and the Borrowers, including limitations on Borrowers’ ability to pay dividends on common stock or preferred stock, and also includes certain events of default, including payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to other obligations, events of bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of control.

The commitments under the PNC Facility will expire and the full outstanding principal amount of the loans, together with accrued and unpaid interest, are due and payable in full on October 10, 2022, unless the commitments are terminated and the outstanding principal amount of the loans are accelerated sooner following an event of default.

In connection with the closing of the PNC Facility, the Company also entered into an Amended and Restated Guaranty and Suretyship Agreement, dated as of October 10, 2017 (the “Revolver Guarantee”), pursuant to which the Company affirmed its unconditional guarantee of the payment and performance of all obligations owing by Borrowers to PNC, as Agent for the benefit of the revolving lenders.

Term Loan Facility

On October 10, 2017, HTC, Holdings, and ARI, as borrowers, and the Company, as guarantor, became obligated under a Term Loan Credit and Security Agreement (the “Term Loan Facility”) with U.S. Bank National Association, as administrative agent and collateral agent (“Term Loan Agent”) and funds advised by FS Investments and such other lenders as may thereafter become a party to the Term Loan Facility (the “Term Loan Lenders”).

Under the terms of the Term Loan Facility, the Borrowers immediately borrowed $105 million pursuant to a term loan (the “Initial Term Loan”) and could borrow up to an additional $25 million for a period of eighteen months after closing to fund additional permitted acquisitions (the “Delayed Draw Commitment”, and together with the Initial Term Loan, the “Term Loans”).

On June 29, 2018, HTC, Holdings and ARI, as borrowers, and the Company as a guarantor, entered into a Limited Waiver and First Amendment to Term Loan Credit and Security Agreement and Other Documents (the “First Amendment”) with U.S. Bank National Association, as collateral agent and administrative agent, and the various lenders thereunder. The First Amendment terminated the Delayed Draw Commitment and provided an interim waiver with respect to compliance with the existing total leverage ratio (“TLR”) covenant at June 30, 2018.

33

The Term Loans mature on October 10, 2023. Principal payments on the Term Loans are required on a quarterly basis, commencing with the quarter ended March 31, 2018, in the amount of 1% per annum of the original principal of the outstanding Term Loans. Commencing with the fiscal year ending December 31, 2018, the Term Loan Facility also requires annual principal payments of up to 50% of Excess Cash Flow (as defined in the Term Loan Facility) if the Company’s Total Leverage Ratio (as defined in the Term Loan Facility) for the applicable year is greater than 2.75 to 1.00. The Term Loan Facility also requires mandatory prepayments of the Term Loans in the event of certain asset dispositions, debt issuances, and casualty and condemnation events. The Term Loans may be prepaid at the option of the Borrowers at par in an amount up to $30 million. Additional prepayments are permitted after the first anniversary of the closing date and were originally subject to a prepayment premium of 3% in year two, 1% in year three and zero in year four and thereafter.

Interest on the Term Loans is generally payable on the earlier of the last day of the interest period applicable to such Eurodollar rate loan and the last day of the Term Loan Facility, as applicable. Interest was originally payable at the rate per annum of the Eurodollar Rate (as defined in the Term Loan Facility) plus 7.25%. The Borrowers have the option of paying 3.00% interest per annum in kind by adding such amount to the principal of the Term Loans during no more than five fiscal quarters during the term of the Term Loan Facility.

Borrowers and the Company granted to the Term Loan Agent, for the benefit of the Term Loan Lenders, a security interest in substantially all of their respective assets, including receivables, equipment, general intangibles (including intellectual property), inventory, subsidiary stock, real property, and certain other assets.

The Term Loan Facility originally contained a financial covenant requiring the Company to maintain a Total Leverage Ratio (TLR) of not greater than 4.75 to 1.00, tested as of the last day of the fiscal quarter. The Term Loan Facility was amended on August 14, 2018, including a waiver of the TLR covenant at June 30, 2018, as described below. The TLR (as defined in the Term Loan Facility) is the ratio of (a) funded debt as of such day to (b) EBITDA for the four consecutive fiscal quarters ending on the last day of such fiscal quarter. Funded debt (as defined in the Term Loan Facility) includes amounts borrowed under the PNC Facility and the Term Loan Facility as well as capitalized lease obligations and other indebtedness for borrowed money maturing more than one year from the date of creation thereof. As of September 30, 2019 and December 31, 2018, the TLR was approximately 13.79 to 1 and 11.82 to 1, respectively.

The Term Loan Facility also contains customary non-financial covenants relating to the Company and the Borrowers, including limitations on their ability to pay dividends on common stock or preferred stock, and also includes certain events of default, including payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to other obligations, events of bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of control.

In connection with the closing of the Term Loan Facility, the Company also entered into a Guaranty and Suretyship Agreement, dated as of October 10, 2017 (the “Term Loan Guarantee”), pursuant to which the Company affirmed its unconditional guarantee of the payment and performance of all obligations owing by Borrowers to Term Loan Agent, as agent for the benefit of the Term Loan Lenders.

The Term Loan Agent and the Agent have entered into an intercreditor agreement governing the relative priority of their security interests granted by the Borrowers and the Guarantor in the collateral, providing that the Agent shall have a first priority security interest in the accounts receivable, inventory, deposit accounts and certain other assets (the “Revolving Credit Priority Collateral”) and the Term Loan Agent shall have a first priority security interest in the equipment, real property, capital stock of subsidiaries and certain other assets (the “Term Loan Priority Collateral”).

On August 14, 2018, HTC, Holdings and ARI, as borrowers, and the Company as a guarantor, entered into a Waiver and Second Amendment to Term Loan Credit and Security Agreement (the “Second Amendment”) with U.S. Bank National Association, as collateral agent and administrative agent, and the various lenders thereunder. The Second Amendment superseded interim waivers and amended the Term Loan Facility, to waive compliance with the existing TLR covenant at June 30, 2018.

In addition, the Second Amendment also: (i) increases the interest rate by 300 basis points effective July 1, 2018; (ii) waives the existing prepayment premium in the Term Loan Facility in the event the term loan is repaid in full prior to March 31, 2020; (iii) adds an exit fee equal to three percent (3.00%) of the outstanding principal balance of the term loans on the date of the Second Amendment (provided, that payment of the exit fee is waived in the event that the term loan is repaid in full prior to January 1, 2020, and provided further that the exit fee is reduced to one-and-one-half percent (1.50%) in the event that the term loan is repaid in full on or after January 1, 2020 but prior to March 31, 2020); (iv) restricted acquisitions and other equity investments prior to September 30, 2018; and (v) required payment of a one-time waiver fee equal to one percent (1.00%) of the outstanding term loans.

34

On November 30, 2018, the Borrowers, and the Company as a guarantor, entered into a Waiver and Third Amendment to Term Loan Credit and Security Agreement (the “Third Amendment”) with U.S. Bank National Association, as collateral agent and administrative agent, and the various lenders thereunder.

The Third Amendment superseded interim waivers and amended the Term Loan Facility to reset the maximum Total Leverage Ratio covenant contained in the Term Loan Facility at the indicated dates as follows: (i) June 30, 2018 - 10.15:1.00; (ii) September 30, 2018 - 12.45:1.00; (iii) December 31, 2018 – 12.75:1.00; (iv) March 31, 2019 – 12.95:1.00; (v) June 30, 2019 – 8.25:1.00; September 30, 2019 – 6.40:1.00; (vi) December 31, 2019 – 5:70:1.00; and (vii) March 31, 2020 and each fiscal quarter thereafter – 4:75:1.00.

The Third Amendment increased the scheduled quarterly principal repayments to $525,000 effective December 31, 2018. In addition the Third Amendment requires a further repayment of principal on or before November 14, 2019 in an amount equal to (x) 100% of Excess Cash Flow (as defined in the Term Loan Facility) for the four fiscal quarter period ended September 30, 2019 if after giving effect to the payment thereof, the Borrowers have minimum aggregate Undrawn Availability (as defined in the Term Loan Facility) of at least $35,000,000, (y) 50% of Excess Cash Flow for the four fiscal quarter period ended September 30, 2019 if after giving effect to the payment thereof, the Borrowers have minimum aggregate Undrawn Availability of at least $15,000,000 but less than $35,000,000, and (z) 0% of Excess Cash Flow for the four fiscal quarter period ended September 30, 2019 if after giving effect to the payment thereof, the Borrowers have minimum aggregate Undrawn Availability less than $15,000,000, with any such payment subject to reduction by the amount of any voluntary prepayments made following the date of the Third Amendment. Any voluntary prepayments will not be subject to the prepayment premium or make-whole provisions of the Term Loan Facility. The Third Amendment also adds a minimum liquidity requirement (consisting of cash plus undrawn availability on the Borrowers’ revolving loan facility) of $28 million, measured monthly.

The Third Amendment also amended the exit fee payable to the term loan lenders to five percent (5.00%) of the outstanding principal balance of the term loans on November 30, 2018 (the “Exit Fee”), which Exit Fee shall be payable in full in cash upon the earlier to occur of (x) repayment in full of the term loans, or (y) any acceleration of the term loans. The Exit Fee will be reduced by one-tenth of one percent (0.10%) for every $1,000,000 in voluntary prepayments made prior to January 1, 2020; provided, that, in no event shall the Exit Fee be reduced below three percent (3.00%) as a result of any such prepayments, (ii) payment of the Exit Fee shall be waived in the event that repayment in full of the term loans occurs prior to January 1, 2020, and (iii) the Exit Fee shall be reduced by an amount equal to fifty percent (50%) of the amount that would otherwise payable in the event that repayment in full occurs on or after January 1, 2020 but prior to March 31, 2020.

On April 17, 2019, the Borrowers and the Company as a guarantor, and ten new subsidiaries of the Borrowers (the “New Subsidiaries”), entered into a Joinder to Term Loan Credit and Security Agreement and Other Documents (the “Joinder”) with U.S. Bank National Association, as collateral agent and administrative agent, and the various lenders thereunder. Pursuant to the Joinder, the New Subsidiaries were added as guarantors under the Term Loan Facility.

The Company evaluated the First, Second and Third Amendments in accordance with the provisions of ASC 470 to determine if the Amendments were a modification or an extinguishment of debt and concluded that the amendments were a modification of the original term loan agreement for accounting purposes. As a result, in 2018 the Company capitalized an additional $1.0 million of deferred financing costs in connection with the Second Amendment, which are being amortized over the remaining term.

Inflation

Inflation has not historically had a material impact on the Company’s operations.

Reliance on Suppliers and Customers

The Company participates in an industry that is highly regulated, and changes in the regulations affecting our business could affect our operating results. Currently the Company purchases virgin HCFC and HFC refrigerants and reclaimable, primarily HCFC and CFC, refrigerants from suppliers and its customers. Under the Act the phase-down of future production of certain virgin HCFC refrigerants commenced in 2010 and is scheduled to be fully phased out by the year 2020, and production of all virgin HCFC refrigerants is scheduled to be phased out by the year 2030. To the extent that the Company is unable to source sufficient quantities of refrigerants or is unable to obtain refrigerants on commercially reasonable terms or experiences a decline in demand and/or price for refrigerants sold by it, the Company could realize reductions in revenue from refrigerant sales, which could have a material adverse effect on the Company’s operating results and financial position.

For the nine month period ended September 30, 2019, there was one customer accounting for 13% of the Company’s revenues. At September 30, 2019 there were $3.3 million of accounts receivable from this customer.

For the nine month period ended September 30, 2018, there were no customers that accounted for 10% or more of the Company’s revenues.

The loss of a principal customer or a decline in the economic prospects of and/or a reduction in purchases of the Company’s products or services by any such customer could have a material adverse effect on the Company’s operating results and financial position.

The Company’s operating results vary from period to period as a result of weather conditions, requirements of potential customers, non-recurring refrigerant and service sales, availability and price of refrigerant products (virgin or reclaimable), changes in reclamation technology and regulations, timing in introduction and/or retrofit or replacement of refrigeration equipment, the rate of expansion of the Company’s operations, and by other factors. The Company’s business is seasonal in nature with peak sales of refrigerants occurring in the first nine months of each year. During past years, the seasonal decrease in sales of refrigerants has resulted in losses particularly in the fourth quarter of the year. In addition, to the extent that there is unseasonably cool weather throughout the spring and summer months, which would adversely affect the demand for refrigerants, there would be a corresponding negative impact on the Company. Delays or inability in securing adequate supplies of refrigerants at peak demand periods, lack of refrigerant demand, increased expenses, declining refrigerant prices and a loss of a principal customer could result in significant losses. There can be no assurance that the foregoing factors will not occur and result in a material adverse effect on the Company’s financial position and significant losses. The Company believes that to a lesser extent there is a similar seasonal element to RefrigerantSide® Service revenues as refrigerant sales.

Recent Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses." This ASU requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, and for interim periods therein. The Company does not expect the amended standard to have a material impact on the Company’s results of operations.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (ASU 2016-02), as amended, which generally requires lessees to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash flows arising from leasing arrangements. In July 2018, the FASB issued ASU No. 2018-11, Leases – Targeted Improvements, as an update to the previously-issued guidance. This update added a transition option which allows for the recognition of a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption without recasting the financial statements in periods prior to adoption. We have used the modified retrospective transition approach in ASU No. 2018-11 and applied the new lease requirements through a cumulative-effect adjustment in the period of adoption. We elected the package of practical expedients permitted under the transition guidance, which allows us to carryforward our historical lease classification, our assessment on whether a contract is or contains a lease, and our initial direct costs for any leases that existed prior to adoption of the new standard. We also elected to combine lease and non-lease components and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of operations on a straight-line basis over the lease term. We recorded approximately $8.1 million as total right-of-use assets and total lease liabilities on our consolidated balance sheet as of January 1, 2019. The Company’s accounting for finance leases remained substantially unchanged. Disclosures related to the amount, timing and uncertainty of cash flows arising from leases are included in Note 5 to the financial statements contained herein.

Item 3 - Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Sensitivity

We are exposed to market risk from fluctuations in interest rates on the PNC Facility and on the Term Loan Facility. The PNC Facility is a $150,000,000 secured facility, and the Term Loan Facility provides for Term Loans of $105,000,000.

There was a $15,183,276 outstanding balance on the PNC Facility as of September 30, 2019. Future interest rate changes on our borrowing under the PNC Facility may have an impact on our consolidated results of operations.

There was a $102,112,500 outstanding balance on the Term Loan Facility as of September 30, 2019. Future interest rate changes on our borrowing under the Term Loans may have an impact on our consolidated results of operations.

If the loan bearing interest rate changed by 1%, the annual effect on interest expense would be approximately $1.1 million as of September 30, 2019.

Refrigerant Market

We are also exposed to market risk from fluctuations in the demand, price and availability of refrigerants. To the extent that the Company is unable to source sufficient quantities of refrigerants or is unable to obtain refrigerants on commercially reasonable terms or experiences a decline in demand and/or price for refrigerants sold by the Company, the Company could realize reductions in revenue from refrigerant sales or write-downs of inventory, which could have a material adverse effect on our consolidated results of operations.

Item 4 - Controls and Procedures

Disclosure Controls and Procedures

The Company, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures, as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended (“Exchange Act”), as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective and provided reasonable assurance that information required to be disclosed in reports filed under the Exchange Act 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 the Company’s management, including its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Because of the inherent limitations in all control systems, any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Furthermore, the Company’s controls and procedures can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the control and misstatements due to error or fraud may occur and not be detected on a timely basis.

37

Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) during the quarter ended September 30, 2019 that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1 - Legal Proceedings

For information regarding pending legal matters, refer to the Legal Proceedings Section in Part I, Item 3 of the Company’s Form 10-K for the year ended December 31, 2018. Except as set forth below, there have been no material changes to such matters during the quarter ended September 30, 2019.

ARI Working Capital Dispute

The Stock Purchase Agreement dated August 9, 2017 (the “SPA”) among Airgas, Inc. (“Airgas”), Hudson Holdings, Inc. and Hudson Technologies, Inc., pursuant to which the Company acquired the stock of ARI, contained a customary post-closing working capital adjustment mechanism. After determination of various undisputed working capital adjustments, and upon subsequent completion of the dispute resolution process provided in the SPA, Hudson was entitled to a total payment from Airgas in the amount of approximately $9.5 million (consisting of $3.5 million of undisputed items and $6.0 million of disputed items awarded by the expert designated pursuant to the SPA). On June 27, 2019, Airgas filed an action in the United States District Court for the District of Delaware captioned Airgas, Inc. v. Hudson Holdings, Inc. and Hudson Technologies, Inc. seeking declaratory judgment to overturn the determination of the disputed working capital items by the expert designated pursuant to the SPA. On August 7, 2019, the parties settled the matter in its entirety, including the litigation. Pursuant to the settlement, Airgas paid Hudson an aggregate working capital adjustment payment of $8.9 million.

Item 1A – Risk Factors

Defaults under our credit facilities raise substantial doubts about our ability to continue as a going concern.

Our consolidated financial statements have been prepared assuming we will continue as a going concern and contemplate the realization of assets and satisfaction of liabilities in the normal course of business. Our ability to continue as a going concern is contingent upon our ability to comply with the financial covenants within our credit agreements. Our level of indebtedness has adversely impacted, and continues to adversely impact, our financial condition, including operating results and liquidity position. Since June 30, 2019, we have not been in compliance with the financial covenants in the Term Loan Facility and the PNC Facility, thus raising substantial doubt as to the ability to continue as a going concern.

We have not been in compliance with the financial covenants set forth in our Term Loan Facility from and after June 30, 2019. We also have not been in compliance with the financial covenant for the four quarters ended June 30, 2019 and September 30, 2019 set forth in the PNC Facility. Each of the foregoing represent an Event of Default, as defined in the respective loan agreements. The occurrence of an Event of Default under both the Term Loan Facility and the PNC Facility provide the respective lenders with the right to declare all amounts under the respective agreements to be immediately due and payable and the respective lenders have the right to terminate the obligation to make loans thereunder, and furthermore allows the respective lenders to exercise any and all other remedies under the applicable agreements. The lenders under both the Term Loan Facility and the PNC Facility have delivered reservation of rights letters. We are currently seeking a waiver and amendment from our lenders to waive prior defaults and reset the financial covenants under both the Term Loan Facility and the PNC Facility. However, there can be no assurance that we will be able to conclude any such waivers or amendments on acceptable terms or at all. If we do not obtain a waiver from our lenders, our indebtedness under the credit facilities would become immediately due and payable, and the lenders could foreclose on their security, which could materially adversely affect our business and future financial condition and could require us to curtail or otherwise cease our existing operations.

Item 3 – Defaults Upon Senior Securities

The Company was not in compliance with the Total Leverage Ratio and the minimum liquidity covenants, calculated as of June 30, 2019 and September 30, 2019, set forth in its Term Loan Facility. At September 30, 2019, the Company’s Total Leverage Ratio was 13.79:1.00 (versus a required Total Leverage Ratio of 6.40:1.00) and the Company’s Liquidity (as defined in the Term Loan Facility) was $23.2 million (versus a required level of $28 million). The Company was also not in compliance with the minimum EBITDA covenant for the four quarters ended June 30, 2019 set forth in the PNC Facility and the Fixed Charge Coverage Ratio (0.40 versus 1.00) covenant for the four quarters ended September 30, 2019 set forth in the PNC Facility.

39

Each of the foregoing represent an Event of Default, as defined in the respective loan agreements. The occurrence of an Event of Default under both the Term Loan Facility and the PNC Facility provide the respective lenders with the right to declare all amounts under the respective agreements to be immediately due and payable and the respective lenders have the right to terminate the obligation to make loans thereunder, and furthermore allows the respective lenders to exercise any and all other remedies under the applicable agreements. The lenders under both the Term Loan Facility and the PNC Facility have delivered reservation of rights letters and the Company has been making interest payments on the PNC Facility at the default rate of interest. The Company is currently seeking a waiver and amendment from its lenders to waive prior defaults and reset the financial covenants under both the Term Loan Facility and the PNC Facility. However, there can be no assurance that the Company will be able to conclude any such waivers or amendments on acceptable terms or at all.

Share-based Compensation

Share-based compensation

Share-based compensation

Note 7 - Share-based compensation

Share-based compensation represents the cost related to share-based awards, typically stock options or stock grants, granted to employees, non-employees, officers and directors. Share-based compensation is measured at grant date, based on the estimated aggregate fair value of the award on the grant date, and such amount is charged to compensation expense on a straight-line basis (net of estimated forfeitures) over the requisite service period. For the nine month periods ended September 30, 2019 and 2018, share-based compensation expense of $0.9 million and $0.6 million, respectively, are reflected in general and administrative expenses in the consolidated Statements of Operations.

Share-based awards have historically been made as stock options, and recently also as stock grants, issued pursuant to the terms of the Company’s stock option and stock incentive plans, (collectively, the “Plans”), described below. The Plans may be administered by the Board of Directors or the Compensation Committee of the Board or by another committee appointed by the Board from among its members as provided in the Plans. Presently, the Plans are administered by the Company’s Compensation Committee of the Board of Directors. As of September 30, 2019, the Plans authorized the issuance of 7,000,000 shares of the Company’s common stock and, as of September 30, 2019 there were 2,717,400 shares of the Company’s common stock available for issuance for future stock option grants or other stock-based awards.

Stock option awards, which allow the recipient to purchase shares of the Company’s common stock at a fixed price, are typically granted at an exercise price equal to the Company’s stock price at the date of grant. Typically, the Company’s stock option awards have vested from immediately to two years from the grant date and have had a contractual term ranging from three to ten years.

Effective September 17, 2014, the Company adopted its 2014 Stock Incentive Plan (“2014 Plan”) pursuant to which 3,000,000 shares of common stock were reserved for issuance (i) upon the exercise of options, designated as either incentive stock options (“ISOs”) under the Internal Revenue Code of 1986, as amended (the “Code”) or nonqualified options, or (ii) as stock, deferred stock or other stock-based awards. ISOs may be granted under the 2014 Plan to employees and officers of the Company. Non-qualified options, stock, deferred stock or other stock-based awards may be granted to consultants, directors (whether or not they are employees), employees or officers of the Company. Stock appreciation rights may also be issued in tandem with stock options. Unless the 2014 Plan is sooner terminated, the ability to grant options or other awards under the 2014 Plan will expire on September 17, 2024.

ISOs granted under the 2014 Plan may not be granted at a price less than the fair market value of the common stock on the date of grant (or 110% of fair market value in the case of persons holding 10% or more of the voting stock of the Company). Nonqualified options granted under the 2014 Plan may not be granted at a price less than the fair market value of the common stock. Options granted under the 2014 Plan expire not more than ten years from the date of grant (five years in the case of ISOs granted to persons holding 10% or more of the voting stock of the Company). Certain options granted may contain a barrier price whereby the options are cancelled once the stock price declines below a predetermined barrier price for five consecutive trading days.

Effective June 7, 2018, the Company adopted its 2018 Stock Incentive Plan (“2018 Plan”) pursuant to which 4,000,000 shares of common stock were reserved for issuance (i) upon the exercise of options, designated as either ISOs under the Code or nonqualified options, or (ii) as stock, deferred stock or other stock-based awards. ISOs may be granted under the 2018 Plan to employees and officers of the Company. Non-qualified options, stock, deferred stock or other stock-based awards may be granted to consultants, directors (whether or not they are employees), employees or officers of the Company. Stock appreciation rights may also be issued in tandem with stock options. Unless the 2018 Plan is sooner terminated, the ability to grant options or other awards under the 2018 Plan will expire on June 7, 2028.

ISOs granted under the 2018 Plan may not be granted at a price less than the fair market value of the common stock on the date of grant (or 110% of fair market value in the case of persons holding 10% or more of the voting stock of the Company). Nonqualified options granted under the 2018 Plan may not be granted at a price less than the fair market value of the common stock. Options granted under the 2018 Plan expire not more than ten years from the date of grant (five years in the case of ISOs granted to persons holding 10% or more of the voting stock of the Company). Certain options granted may contain a barrier price whereby the options are cancelled once the stock price declines below a predetermined barrier price for five consecutive trading days.

All stock options have been granted to employees and non-employees at exercise prices equal to or in excess of the market value of the underlying common stock on the date of the grant.

The Company determines the fair value of share-based awards at the grant date by using the Black-Scholes option-pricing model, and is incorporating the simplified method to compute expected lives of share-based awards. There were options to purchase 524,800 and 307,355 shares of common stock granted during the nine month periods ended September 30, 2019 and 2018, respectively.

A summary of the activity for stock options issued under the Company’s Plans for the indicated periods is presented below:

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Note 1 - Summary of Significant Accounting Policies

Business

Hudson Technologies, Inc., incorporated under the laws of New York on January 11, 1991, is a refrigerant services company providing innovative solutions to recurring problems within the refrigeration industry. The Company’s operations consist of one reportable segment. The Company’s products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems, and include refrigerant and industrial gas sales, refrigerant management services consisting primarily of reclamation of refrigerants and RefrigerantSide® Services performed at a customer’s site, consisting of system decontamination to remove moisture, oils and other contaminants. In addition, the Company’s SmartEnergy OPS® service is a web-based real time continuous monitoring service applicable to a facility’s refrigeration systems and other energy systems. The Company’s Chiller Chemistry® and Chill Smart® services are also predictive and diagnostic service offerings. As a component of the Company’s products and services, the Company also generates carbon offset projects. The Company operates principally through its wholly-owned subsidiaries, Hudson Technologies Company and Aspen Refrigerants, Inc. Unless the context requires otherwise, references to the “Company”, “Hudson”, “we", “us”, “our”, or similar pronouns refer to Hudson Technologies, Inc. and its subsidiaries.

In preparing the accompanying consolidated financial statements, and in accordance with Accounting Standards Codification (ASC) 855‑10 “Subsequent Events”, the Company’s management has evaluated subsequent events through the date that the financial statements were filed.

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial statements and with the instructions of Regulation S-X. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. The financial information included in this quarterly report should be read in conjunction with the Company’s audited financial statements and related notes thereto for the year ended December 31, 2018. Operating results for the nine month period ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.

In the opinion of management, all estimates and adjustments considered necessary for a fair presentation have been included and all such adjustments were normal and recurring.

Consolidation

The consolidated financial statements represent all companies of which Hudson directly or indirectly has majority ownership or otherwise controls. Significant intercompany accounts and transactions have been eliminated. The Company’s consolidated financial statements include the accounts of wholly-owned subsidiaries Hudson Holdings, Inc., Hudson Technologies Company and Aspen Refrigerants, Inc. The Company does not present a statement of comprehensive income (loss) as its comprehensive income (loss) is the same as its net income (loss).

Going Concern

The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern and contemplate the realization of assets and satisfaction of liabilities in the normal course of business. The Company's ability to continue as a going concern is contingent upon its ability to comply with the financial covenants within its credit agreements, referred to in Note 8. The Company's level of indebtedness has adversely impacted, and continues to adversely impact, the Company's financial condition, including operating results and liquidity position. As of June 30, 2019 and September 30, 2019, the Company was not in compliance with the financial covenants in the Term Loan Facility and the PNC Facility, thus raising substantial doubt as to the ability to continue as a going concern within one year after the date the financial statements were issued. The Company has satisfied all of its debt payment obligations on a timely basis and had over $14 million of cash on hand and $23 million of availability pursuant to the borrowing base formula in the PNC Facility as of September 30, 2019; and is working with its lenders to obtain a waiver and amendment of its credit facilities. However, there can be no assurance that the Company will be able to conclude any such waivers or amendments on acceptable terms or at all.

The accompanying consolidated financial statements do not include any adjustments related to the recoverability and classification of assets or the amounts and classifications of liabilities or any other adjustments that might be necessary should the Company be unable to continue as a going concern.

Fair Value of Financial Instruments

The carrying values of financial instruments including trade accounts receivable and accounts payable approximate fair value at September 30, 2019 and December 31, 2018, because of the relatively short maturity of these instruments. The carrying value of debt approximates fair value, due to the variable rate nature of the debt, as of September 30, 2019 and December 31, 2018.

Credit Risk

Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of temporary cash investments and trade accounts receivable. The Company maintains its temporary cash investments in highly-rated financial institutions and, at times, the balances exceed FDIC insurance coverage. The Company’s trade accounts receivable are primarily due from companies throughout the United States. The Company reviews each customer’s credit history before extending credit.

The Company establishes an allowance for doubtful accounts based on factors associated with the credit risk of specific accounts, historical trends, and other information. The carrying value of the Company’s accounts receivable is reduced by the established allowance for doubtful accounts. The allowance for doubtful accounts includes any accounts receivable balances that are determined to be uncollectible, along with a general reserve for the remaining accounts receivable balances. The Company adjusts its reserves based on factors that affect the collectability of the accounts receivable balances.

For the nine month period ended September 30, 2019, there was one customer accounting for 13% of the Company’s revenues. At September 30, 2019 there were $3.3 million of accounts receivable from this customer.

For the nine month period ended September 30, 2018, there were no customers that accounted for 10% or more of the Company’s revenues.

The loss of a principal customer or a decline in the economic prospects of and/or a reduction in purchases of the Company’s products or services by any such customer could have a material adverse effect on the Company’s operating results and financial position.

Cash and Cash Equivalents

Temporary investments with original maturities of ninety days or less are included in cash and cash equivalents.

Inventories

Inventories, consisting primarily of refrigerant products available for sale, are stated at the lower of cost, on a first-in first-out basis, or net realizable value. Where the market price of inventory is less than the related cost, the Company may be required to write down its inventory through a lower of cost or net realizable value adjustment, the impact of which would be reflected in cost of sales on the Consolidated Statements of Operations. Any such adjustment would be based on management’s judgment regarding future demand and market conditions and analysis of historical experience.

Property, Plant and Equipment

Property, plant and equipment are stated at cost, including internally manufactured equipment. The cost to complete equipment that is under construction is not considered to be material to the Company’s financial position. Provision for depreciation is recorded (for financial reporting purposes) using the straight-line method over the useful lives of the respective assets. Leasehold improvements are amortized on a straight-line basis over the shorter of economic life or terms of the respective leases. Costs of maintenance and repairs are charged to expense when incurred.

Due to the specialized nature of the Company’s business, it is possible that the Company’s estimates of equipment useful life periods may change in the future.

Goodwill

The Company has made acquisitions that included a significant amount of goodwill and other intangible assets. The Company applies the purchase method of accounting for acquisitions, which among other things, requires the recognition of goodwill (which represents the excess of the purchase price of the acquisition over the fair value of the net assets acquired and identified intangible assets). We test our goodwill for impairment on an annual basis (the first day of the fourth quarter) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of an asset below its carrying value. Other intangible assets that meet certain criteria are amortized over their estimated useful lives.

Beginning in 2017, the Company adopted, on a prospective basis, ASU No. 2017-04, which simplifies the accounting for goodwill impairment by eliminating Step 2 of the prior goodwill impairment test that required a hypothetical purchase price allocation to measure goodwill impairment. Under the new standard, a company will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value.

An impairment charge would be recognized when the carrying amount exceeds the estimated fair value of a reporting unit. These impairment evaluations use many assumptions and estimates in determining an impairment loss, including certain assumptions and estimates related to future earnings. If the Company does not achieve its earnings objectives, the assumptions and estimates underlying these impairment evaluations could be adversely affected, which could result in an asset impairment charge that would negatively impact operating results. The Company’s performance has continued to be negatively impacted by the challenging pricing environment affecting the industry and the market during 2019 resulting in an increase in net realizable value adjustments for certain gases; however, the Company’s sales volume has increased in 2019 when compared to 2018.  The Company determined as of September 30, 2019, that the year-to-date decline in revenue and operating loss, along with the decrease in the Company’s stock price during 2019 represented a triggering event which  required a goodwill impairment test. Based on these indicators, the Company quantitatively evaluated its goodwill for impairment as of September 30, 2019 and determined that goodwill was not impaired.

Revenues and Cost of Sales

Beginning on January 1, 2018, the Company adopted, on a modified retrospective basis, Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers, which provides accounting guidance related to the recognition of revenue from contracts with customers. Based on the evaluation performed, the Company concluded that the adoption of this standard had no impact on its financial position, results of operations or cash flows and did not have a significant impact on its internal controls over financial reporting.

The Company’s products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems. Most of the Company’s revenues are realized from the sale of refrigerant and industrial gases and related products. The Company also generates revenue from refrigerant management services performed at a customer’s site and in-house. The Company conducts its business primarily within the US.

The Company applies the FASB’s guidance on revenue recognition, which requires the Company to recognize revenue in an amount that reflects the consideration the Company expects to be entitled in exchange for goods or services transferred to its customers. In most instances, the Company’s contract with a customer is the customer’s purchase order and the sales price to the customer is fixed. For certain customers, the Company may also enter into a sales agreement outlining a framework of terms and conditions applicable to future purchase orders received from that customer. Because the Company’s contracts with customers are typically for a single customer purchase order, the duration of the contract is usually less than one year. The Company’s performance obligations related to product sales are satisfied at a point in time, which may occur upon shipment of the product or receipt by the customer, depending on the terms of the arrangement. The Company’s performance obligations related to reclamation and RefrigerantSide® services are generally satisfied at a point in time when the service is performed. Accordingly revenues are recorded upon the shipment of the product, or in certain instances upon receipt by the customer, or the completion of the service.

In July 2016 the Company was awarded, as prime contractor, a five-year contract, including a five-year renewal option, by the United States Defense Logistics Agency (“DLA”) for the management, supply, and sale of refrigerants, compressed gases, cylinders and related services. Due to the contract containing multiple performance obligations, the Company assessed the arrangement in accordance with ASC 606. The Company determined that the sale of refrigerants and the management services provided under the contract each have stand-alone value. Accordingly, the performance obligations related to the sale of refrigerants is satisfied at a point in time, mainly when the customer receives and obtains control of the product. The performance obligation related to management service revenue is satisfied over time and revenue is recognized on a straight-line basis over the term of the arrangement as the management services are provided; such management fees are included in the below table as Product and related sales and were approximately $1.8 million for each of the nine months ended September 30, 2019 and 2018.

Cost of sales is recorded based on the cost of products shipped or services performed and related direct operating costs of the Company’s facilities. In general, the Company performs shipping and handling services for its customers in connection with the delivery of refrigerant and other products. In accordance with ASC 606‑10‑25‑18B, the Company has elected to account for such shipping and handling as activities to fulfill the promise to transfer the good. To the extent that the Company charges its customers shipping fees, such amounts are included as a component of revenue and the corresponding costs are included as a component of cost of sales.

The Company’s revenues are derived from Product and related sales and RefrigerantSide® services revenues. The revenues for each of these lines are as follows:

		Three Months				Nine Months
		ended September 30,				ended September 30,
(in thousands)	2019		2018		2019		2018
Product and related sales	$	44,518	$	39,787	$	132,705	$	137,336
RefrigerantSide ® services		1,113		758		3,601		3,468
Total	$	45,631	$	40,545	$	136,306	$	140,804

Income Taxes

The Company is taxed at statutory corporate income tax rates after adjusting income reported for financial statement purposes for certain items. Current income tax expense (benefit) reflects the tax results of revenues and expenses currently taxable or deductible. The Company utilizes the asset and liability method of accounting for deferred income taxes, which provides for the recognition of deferred tax assets or liabilities, based on enacted tax rates and laws, for the differences between the financial and income tax reporting bases of assets and liabilities.

The tax benefit associated with the Company’s net operating loss carry forwards (“NOLs”) is recognized to the extent that the Company expects to realize future taxable income. As a result of a prior “change in control”, as defined by the Internal Revenue Service, the Company’s ability to utilize its existing NOLs is subject to certain annual limitations. To the extent that the Company utilizes its NOLs, it will not pay tax on such income. However, to the extent that the Company’s net income, if any, exceeds the annual NOL limitation, it will pay income taxes based on the then existing statutory rates. In addition, certain states either do not allow or limit NOLs and as such the Company will be liable for certain state income taxes.

As of September 30, 2019, the Company had NOLs of approximately $39.1 million, of which $33.7 million have no expiration date (subject to annual limitations of 80% of tax earnings) and $5.4 million expire through 2023 (subject to annual limitations of approximately $1.3 million). As of September 30, 2019, the Company had state tax NOLs of approximately $20.0 million expiring in various years. We review the likelihood that we will realize the benefit of our deferred tax assets, and therefore the need for valuation allowances, on an annual basis in the fourth quarter of the year, and more frequently if events indicate that a review is required. In determining the requirement for a valuation allowance, the historical and projected financial results are considered, along with all other available positive and negative evidence.

Concluding that a valuation allowance is not required is difficult when there is significant negative evidence that is objective and verifiable, such as cumulative losses in recent years. We utilize a rolling twelve quarters of pre-tax income or loss adjusted for significant permanent book to tax differences, as well as non-recurring items, as a measure of our cumulative results in recent years. Based on the cumulative operating loss experienced through December 31, 2018, our analysis indicated that we had cumulative three year historical losses on this basis, which represented significant negative evidence that is objective and verifiable and, therefore, difficult to overcome. Based on our assessment as of December 31, 2018, we concluded that due to the uncertainty that the deferred tax assets will not be fully realized in the future, we recorded a valuation allowance of approximately $11.3 million during the year ended December 31, 2018 and increased the valuation allowance to $16.9 million as of September 30, 2019 due to additional losses.

As a result of an Internal Revenue Service audit, the 2013 and prior federal tax years have been closed. The Company operates in many states throughout the United States and, as of September 30, 2019, the various states’ statutes of limitations remain open for tax years subsequent to 2010. The Company recognizes interest and penalties, if any, relating to income taxes as a component of the provision for income taxes.

The Company evaluates uncertain tax positions, if any, by determining if it is more likely than not to be sustained upon examination by the taxing authorities. As of September 30, 2019, and December 31, 2018, the Company believes it had no uncertain tax positions.

Income (Loss) per Common and Equivalent Shares

If dilutive, common equivalent shares (common shares assuming exercise of options) utilizing the treasury stock method are considered in the presentation of diluted loss per share. The reconciliation of shares used to determine net income (loss) per share is as follows (dollars in thousands, unaudited):

	Three Months				Nine Months
	ended September 30,				ended September 30,
	2019		2018		2019		2018
Net income (loss)	$	2,667	$	(13,880)	$	(15,169)	$	(47,552)
Weighted average number of shares  - basic and diluted		42,618,391		42,530,476		42,608,396		42,445,926

During the three month periods ended September 30, 2019 and 2018, certain options aggregating 4,807,377 and 785,697 shares, respectively, have been excluded from the calculation of diluted shares, due to the fact that their effect would be anti-dilutive.

During the nine month periods ended September 30, 2019 and 2018, certain options aggregating 4,807,377 and 785,697 shares, respectively, have been excluded from the calculation of diluted shares, due to the fact that their effect would be anti-dilutive.

Estimates and Risks

The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the use of estimates and assumptions that affect the amounts reported in these financial statements and footnotes. The Company considers these accounting estimates to be critical in the preparation of the accompanying consolidated financial statements. The Company uses information available at the time the estimates are made. However, these estimates could change materially if different information or assumptions were used. Additionally, these estimates may not ultimately reflect the actual amounts of the final transactions that occur. The Company utilizes both internal and external sources to evaluate potential current and future liabilities for various commitments and contingencies. In the event that the assumptions or conditions change in the future, the estimates could differ from the original estimates.

Several of the Company’s accounting policies involve significant judgments, uncertainties and estimates. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. To the extent that actual results differ from management’s judgments and estimates, there could be a material adverse effect on the Company. On a continuous basis, the Company evaluates its estimates, including, but not limited to, those estimates related to its allowance for doubtful accounts, inventory reserves, and valuation allowance for the deferred tax assets relating to its NOLs and commitments and contingencies. With respect to accounts receivable, the Company estimates the necessary allowance for doubtful accounts based on both historical and anticipated trends of payment history and the ability of the customer to fulfill its obligations. For inventory, the Company evaluates both current and anticipated sales prices of its products to determine if a write down of inventory to net realizable value is necessary. In determining the Company’s valuation allowance for its deferred tax assets, the Company assesses its ability to generate taxable income in the future.

The Company participates in an industry that is highly regulated, and changes in the regulations affecting our business could affect our operating results. Currently the Company purchases virgin hydrochlorofluorocarbon (“HCFC”) and hydrofluorocarbon (“HFC”) refrigerants and reclaimable, primarily HCFC, HFC and chlorofluorocarbon (“CFC”), refrigerants from suppliers and its customers. Effective January 1, 1996, the Clean Air Act (the “Act”) prohibited the production of virgin CFC refrigerants and limited the production of virgin HCFC refrigerants. Effective January 2004, the Act further limited the production of virgin HCFC refrigerants and federal regulations were enacted which established production and consumption allowances for HCFC refrigerants which imposed limitations on the importation of certain virgin HCFC refrigerants. Under the Act, production of certain virgin HCFC refrigerants is scheduled to be phased out during the period 2010 through 2020, and production of all virgin HCFC refrigerants is scheduled to be phased out by 2030. In October 2014, the EPA published a final rule providing further reductions in the production and consumption allowances for virgin HCFC refrigerants for the years 2015 through 2019 (the “Final Rule”). In the Final Rule, the EPA established a linear draw down for the production or importation of virgin HCFC‑22 that started at approximately 22 million pounds in 2015 and was reduced by approximately 4.5 million pounds each year ending at zero in 2020.

To the extent that the Company is unable to source sufficient quantities of refrigerants or is unable to obtain refrigerants on commercially reasonable terms or experiences a decline in demand and/or price for refrigerants sold by the Company, the Company could realize reductions in revenue from refrigerant sales, which could have a material adverse effect on its operating results and its financial position.

The Company is subject to various legal proceedings. The Company assesses the merit and potential liability associated with each of these proceedings. In addition, the Company estimates potential liability, if any, related to these matters. To the extent that these estimates are not accurate, or circumstances change in the future, the Company could realize liabilities, which could have a material adverse effect on its operating results and its financial position.

Impairment of Long-lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less the cost to sell.

Recent Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016‑13, "Financial Instruments - Credit Losses." This ASU requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, and for interim periods therein. The Company does not expect the amended standard to have a material impact on the Company’s results of operations.

In February 2016, the FASB issued Accounting Standards Update No. 2016‑02, Leases (Topic 842) (ASU 2016‑02), as amended, which generally requires lessees to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash flows arising from leasing arrangements. In July 2018, the FASB issued ASU No. 2018‑11, Leases – Targeted Improvements, as an update to the previously-issued guidance. This update added a transition option which allows for the recognition of a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption without recasting the financial statements in periods prior to adoption. We have used the modified retrospective transition approach in ASU No. 2018‑11 and applied the new lease requirements through a cumulative-effect adjustment in the period of adoption. We elected the package of practical expedients permitted under the transition guidance, which allows us to carryforward our historical lease classification, our assessment on whether a contract is or contains a lease, and our initial direct costs for any leases that existed prior to adoption of the new standard. We also elected to combine lease and non-lease components and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of operations on a straight-line basis over the lease term. We recorded approximately $8.1 million as total right-of-use assets and total lease liabilities on our consolidated balance sheet as of January 1, 2019. The Company’s accounting for finance leases remained substantially unchanged. Disclosures relating to the amount, timing and uncertainty of cash flows arising from leases are included in Note 5.

Summary of Significant Accounting Policies

Business

Business

Hudson Technologies, Inc., incorporated under the laws of New York on January 11, 1991, is a refrigerant services company providing innovative solutions to recurring problems within the refrigeration industry. The Company’s operations consist of one reportable segment. The Company’s products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems, and include refrigerant and industrial gas sales, refrigerant management services consisting primarily of reclamation of refrigerants and RefrigerantSide® Services performed at a customer’s site, consisting of system decontamination to remove moisture, oils and other contaminants. In addition, the Company’s SmartEnergy OPS® service is a web-based real time continuous monitoring service applicable to a facility’s refrigeration systems and other energy systems. The Company’s Chiller Chemistry® and Chill Smart® services are also predictive and diagnostic service offerings. As a component of the Company’s products and services, the Company also generates carbon offset projects. The Company operates principally through its wholly-owned subsidiaries, Hudson Technologies Company and Aspen Refrigerants, Inc. Unless the context requires otherwise, references to the “Company”, “Hudson”, “we", “us”, “our”, or similar pronouns refer to Hudson Technologies, Inc. and its subsidiaries.

In preparing the accompanying consolidated financial statements, and in accordance with Accounting Standards Codification (ASC) 855‑10 “Subsequent Events”, the Company’s management has evaluated subsequent events through the date that the financial statements were filed.

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial statements and with the instructions of Regulation S-X. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. The financial information included in this quarterly report should be read in conjunction with the Company’s audited financial statements and related notes thereto for the year ended December 31, 2018. Operating results for the nine month period ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.

In the opinion of management, all estimates and adjustments considered necessary for a fair presentation have been included and all such adjustments were normal and recurring.

Consolidation

Consolidation

The consolidated financial statements represent all companies of which Hudson directly or indirectly has majority ownership or otherwise controls. Significant intercompany accounts and transactions have been eliminated. The Company’s consolidated financial statements include the accounts of wholly-owned subsidiaries Hudson Holdings, Inc., Hudson Technologies Company and Aspen Refrigerants, Inc. The Company does not present a statement of comprehensive income (loss) as its comprehensive income (loss) is the same as its net income (loss).

Going Concern

Going Concern

The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern and contemplate the realization of assets and satisfaction of liabilities in the normal course of business. The Company's ability to continue as a going concern is contingent upon its ability to comply with the financial covenants within its credit agreements, referred to in Note 8. The Company's level of indebtedness has adversely impacted, and continues to adversely impact, the Company's financial condition, including operating results and liquidity position. As of June 30, 2019 and September 30, 2019, the Company was not in compliance with the financial covenants in the Term Loan Facility and the PNC Facility, thus raising substantial doubt as to the ability to continue as a going concern within one year after the date the financial statements were issued. The Company has satisfied all of its debt payment obligations on a timely basis and had over $14 million of cash on hand and $23 million of availability pursuant to the borrowing base formula in the PNC Facility as of September 30, 2019; and is working with its lenders to obtain a waiver and amendment of its credit facilities. However, there can be no assurance that the Company will be able to conclude any such waivers or amendments on acceptable terms or at all.

The accompanying consolidated financial statements do not include any adjustments related to the recoverability and classification of assets or the amounts and classifications of liabilities or any other adjustments that might be necessary should the Company be unable to continue as a going concern.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The carrying values of financial instruments including trade accounts receivable and accounts payable approximate fair value at September 30, 2019 and December 31, 2018, because of the relatively short maturity of these instruments. The carrying value of debt approximates fair value, due to the variable rate nature of the debt, as of September 30, 2019 and December 31, 2018.

Credit Risk

Credit Risk

Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of temporary cash investments and trade accounts receivable. The Company maintains its temporary cash investments in highly-rated financial institutions and, at times, the balances exceed FDIC insurance coverage. The Company’s trade accounts receivable are primarily due from companies throughout the United States. The Company reviews each customer’s credit history before extending credit.

The Company establishes an allowance for doubtful accounts based on factors associated with the credit risk of specific accounts, historical trends, and other information. The carrying value of the Company’s accounts receivable is reduced by the established allowance for doubtful accounts. The allowance for doubtful accounts includes any accounts receivable balances that are determined to be uncollectible, along with a general reserve for the remaining accounts receivable balances. The Company adjusts its reserves based on factors that affect the collectability of the accounts receivable balances.

For the nine month period ended September 30, 2019, there was one customer accounting for 13% of the Company’s revenues. At September 30, 2019 there were $3.3 million of accounts receivable from this customer.

For the nine month period ended September 30, 2018, there were no customers that accounted for 10% or more of the Company’s revenues.

The loss of a principal customer or a decline in the economic prospects of and/or a reduction in purchases of the Company’s products or services by any such customer could have a material adverse effect on the Company’s operating results and financial position.

Cash and Cash Equivalents

Cash and Cash Equivalents

Temporary investments with original maturities of ninety days or less are included in cash and cash equivalents.

Inventories

Inventories

Inventories, consisting primarily of refrigerant products available for sale, are stated at the lower of cost, on a first-in first-out basis, or net realizable value. Where the market price of inventory is less than the related cost, the Company may be required to write down its inventory through a lower of cost or net realizable value adjustment, the impact of which would be reflected in cost of sales on the Consolidated Statements of Operations. Any such adjustment would be based on management’s judgment regarding future demand and market conditions and analysis of historical experience.

Property, Plant and Equipment

Property, Plant and Equipment

Property, plant and equipment are stated at cost, including internally manufactured equipment. The cost to complete equipment that is under construction is not considered to be material to the Company’s financial position. Provision for depreciation is recorded (for financial reporting purposes) using the straight-line method over the useful lives of the respective assets. Leasehold improvements are amortized on a straight-line basis over the shorter of economic life or terms of the respective leases. Costs of maintenance and repairs are charged to expense when incurred.

Due to the specialized nature of the Company’s business, it is possible that the Company’s estimates of equipment useful life periods may change in the future.

Goodwill

Goodwill

The Company has made acquisitions that included a significant amount of goodwill and other intangible assets. The Company applies the purchase method of accounting for acquisitions, which among other things, requires the recognition of goodwill (which represents the excess of the purchase price of the acquisition over the fair value of the net assets acquired and identified intangible assets). We test our goodwill for impairment on an annual basis (the first day of the fourth quarter) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of an asset below its carrying value. Other intangible assets that meet certain criteria are amortized over their estimated useful lives.

Beginning in 2017, the Company adopted, on a prospective basis, ASU No. 2017-04, which simplifies the accounting for goodwill impairment by eliminating Step 2 of the prior goodwill impairment test that required a hypothetical purchase price allocation to measure goodwill impairment. Under the new standard, a company will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value.

An impairment charge would be recognized when the carrying amount exceeds the estimated fair value of a reporting unit. These impairment evaluations use many assumptions and estimates in determining an impairment loss, including certain assumptions and estimates related to future earnings. If the Company does not achieve its earnings objectives, the assumptions and estimates underlying these impairment evaluations could be adversely affected, which could result in an asset impairment charge that would negatively impact operating results. The Company’s performance has continued to be negatively impacted by the challenging pricing environment affecting the industry and the market during 2019 resulting in an increase in net realizable value adjustments for certain gases; however, the Company’s sales volume has increased in 2019 when compared to 2018.  The Company determined as of September 30, 2019, that the year-to-date decline in revenue and operating loss, along with the decrease in the Company’s stock price during 2019 represented a triggering event which  required a goodwill impairment test. Based on these indicators, the Company quantitatively evaluated its goodwill for impairment as of September 30, 2019 and determined that goodwill was not impaired.

Revenues and Cost of Sales

Revenues and Cost of Sales

Beginning on January 1, 2018, the Company adopted, on a modified retrospective basis, Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers, which provides accounting guidance related to the recognition of revenue from contracts with customers. Based on the evaluation performed, the Company concluded that the adoption of this standard had no impact on its financial position, results of operations or cash flows and did not have a significant impact on its internal controls over financial reporting.

The Company’s products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems. Most of the Company’s revenues are realized from the sale of refrigerant and industrial gases and related products. The Company also generates revenue from refrigerant management services performed at a customer’s site and in-house. The Company conducts its business primarily within the US.

The Company applies the FASB’s guidance on revenue recognition, which requires the Company to recognize revenue in an amount that reflects the consideration the Company expects to be entitled in exchange for goods or services transferred to its customers. In most instances, the Company’s contract with a customer is the customer’s purchase order and the sales price to the customer is fixed. For certain customers, the Company may also enter into a sales agreement outlining a framework of terms and conditions applicable to future purchase orders received from that customer. Because the Company’s contracts with customers are typically for a single customer purchase order, the duration of the contract is usually less than one year. The Company’s performance obligations related to product sales are satisfied at a point in time, which may occur upon shipment of the product or receipt by the customer, depending on the terms of the arrangement. The Company’s performance obligations related to reclamation and RefrigerantSide® services are generally satisfied at a point in time when the service is performed. Accordingly revenues are recorded upon the shipment of the product, or in certain instances upon receipt by the customer, or the completion of the service.

In July 2016 the Company was awarded, as prime contractor, a five-year contract, including a five-year renewal option, by the United States Defense Logistics Agency (“DLA”) for the management, supply, and sale of refrigerants, compressed gases, cylinders and related services. Due to the contract containing multiple performance obligations, the Company assessed the arrangement in accordance with ASC 606. The Company determined that the sale of refrigerants and the management services provided under the contract each have stand-alone value. Accordingly, the performance obligations related to the sale of refrigerants is satisfied at a point in time, mainly when the customer receives and obtains control of the product. The performance obligation related to management service revenue is satisfied over time and revenue is recognized on a straight-line basis over the term of the arrangement as the management services are provided; such management fees are included in the below table as Product and related sales and were approximately $1.8 million for each of the nine months ended September 30, 2019 and 2018.

Cost of sales is recorded based on the cost of products shipped or services performed and related direct operating costs of the Company’s facilities. In general, the Company performs shipping and handling services for its customers in connection with the delivery of refrigerant and other products. In accordance with ASC 606‑10‑25‑18B, the Company has elected to account for such shipping and handling as activities to fulfill the promise to transfer the good. To the extent that the Company charges its customers shipping fees, such amounts are included as a component of revenue and the corresponding costs are included as a component of cost of sales.

The Company’s revenues are derived from Product and related sales and RefrigerantSide® services revenues. The revenues for each of these lines are as follows:

		Three Months				Nine Months
		ended September 30,				ended September 30,
(in thousands)	2019		2018		2019		2018
Product and related sales	$	44,518	$	39,787	$	132,705	$	137,336
RefrigerantSide ® services		1,113		758		3,601		3,468
Total	$	45,631	$	40,545	$	136,306	$	140,804

Income Taxes

Income Taxes

The Company is taxed at statutory corporate income tax rates after adjusting income reported for financial statement purposes for certain items. Current income tax expense (benefit) reflects the tax results of revenues and expenses currently taxable or deductible. The Company utilizes the asset and liability method of accounting for deferred income taxes, which provides for the recognition of deferred tax assets or liabilities, based on enacted tax rates and laws, for the differences between the financial and income tax reporting bases of assets and liabilities.

The tax benefit associated with the Company’s net operating loss carry forwards (“NOLs”) is recognized to the extent that the Company expects to realize future taxable income. As a result of a prior “change in control”, as defined by the Internal Revenue Service, the Company’s ability to utilize its existing NOLs is subject to certain annual limitations. To the extent that the Company utilizes its NOLs, it will not pay tax on such income. However, to the extent that the Company’s net income, if any, exceeds the annual NOL limitation, it will pay income taxes based on the then existing statutory rates. In addition, certain states either do not allow or limit NOLs and as such the Company will be liable for certain state income taxes.

As of September 30, 2019, the Company had NOLs of approximately $39.1 million, of which $33.7 million have no expiration date (subject to annual limitations of 80% of tax earnings) and $5.4 million expire through 2023 (subject to annual limitations of approximately $1.3 million). As of September 30, 2019, the Company had state tax NOLs of approximately $20.0 million expiring in various years. We review the likelihood that we will realize the benefit of our deferred tax assets, and therefore the need for valuation allowances, on an annual basis in the fourth quarter of the year, and more frequently if events indicate that a review is required. In determining the requirement for a valuation allowance, the historical and projected financial results are considered, along with all other available positive and negative evidence.

Concluding that a valuation allowance is not required is difficult when there is significant negative evidence that is objective and verifiable, such as cumulative losses in recent years. We utilize a rolling twelve quarters of pre-tax income or loss adjusted for significant permanent book to tax differences, as well as non-recurring items, as a measure of our cumulative results in recent years. Based on the cumulative operating loss experienced through December 31, 2018, our analysis indicated that we had cumulative three year historical losses on this basis, which represented significant negative evidence that is objective and verifiable and, therefore, difficult to overcome. Based on our assessment as of December 31, 2018, we concluded that due to the uncertainty that the deferred tax assets will not be fully realized in the future, we recorded a valuation allowance of approximately $11.3 million during the year ended December 31, 2018 and increased the valuation allowance to $16.9 million as of September 30, 2019 due to additional losses.

As a result of an Internal Revenue Service audit, the 2013 and prior federal tax years have been closed. The Company operates in many states throughout the United States and, as of September 30, 2019, the various states’ statutes of limitations remain open for tax years subsequent to 2010. The Company recognizes interest and penalties, if any, relating to income taxes as a component of the provision for income taxes.

The Company evaluates uncertain tax positions, if any, by determining if it is more likely than not to be sustained upon examination by the taxing authorities. As of September 30, 2019, and December 31, 2018, the Company believes it had no uncertain tax positions.

Income (Loss) per Common and Equivalent Shares

Income (Loss) per Common and Equivalent Shares

If dilutive, common equivalent shares (common shares assuming exercise of options) utilizing the treasury stock method are considered in the presentation of diluted loss per share. The reconciliation of shares used to determine net income (loss) per share is as follows (dollars in thousands, unaudited):

	Three Months				Nine Months
	ended September 30,				ended September 30,
	2019		2018		2019		2018
Net income (loss)	$	2,667	$	(13,880)	$	(15,169)	$	(47,552)
Weighted average number of shares  - basic and diluted		42,618,391		42,530,476		42,608,396		42,445,926

During the three month periods ended September 30, 2019 and 2018, certain options aggregating 4,807,377 and 785,697 shares, respectively, have been excluded from the calculation of diluted shares, due to the fact that their effect would be anti-dilutive.

During the nine month periods ended September 30, 2019 and 2018, certain options aggregating 4,807,377 and 785,697 shares, respectively, have been excluded from the calculation of diluted shares, due to the fact that their effect would be anti-dilutive.

Estimates and Risks

Estimates and Risks

The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the use of estimates and assumptions that affect the amounts reported in these financial statements and footnotes. The Company considers these accounting estimates to be critical in the preparation of the accompanying consolidated financial statements. The Company uses information available at the time the estimates are made. However, these estimates could change materially if different information or assumptions were used. Additionally, these estimates may not ultimately reflect the actual amounts of the final transactions that occur. The Company utilizes both internal and external sources to evaluate potential current and future liabilities for various commitments and contingencies. In the event that the assumptions or conditions change in the future, the estimates could differ from the original estimates.

Several of the Company’s accounting policies involve significant judgments, uncertainties and estimates. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. To the extent that actual results differ from management’s judgments and estimates, there could be a material adverse effect on the Company. On a continuous basis, the Company evaluates its estimates, including, but not limited to, those estimates related to its allowance for doubtful accounts, inventory reserves, and valuation allowance for the deferred tax assets relating to its NOLs and commitments and contingencies. With respect to accounts receivable, the Company estimates the necessary allowance for doubtful accounts based on both historical and anticipated trends of payment history and the ability of the customer to fulfill its obligations. For inventory, the Company evaluates both current and anticipated sales prices of its products to determine if a write down of inventory to net realizable value is necessary. In determining the Company’s valuation allowance for its deferred tax assets, the Company assesses its ability to generate taxable income in the future.

The Company participates in an industry that is highly regulated, and changes in the regulations affecting our business could affect our operating results. Currently the Company purchases virgin hydrochlorofluorocarbon (“HCFC”) and hydrofluorocarbon (“HFC”) refrigerants and reclaimable, primarily HCFC, HFC and chlorofluorocarbon (“CFC”), refrigerants from suppliers and its customers. Effective January 1, 1996, the Clean Air Act (the “Act”) prohibited the production of virgin CFC refrigerants and limited the production of virgin HCFC refrigerants. Effective January 2004, the Act further limited the production of virgin HCFC refrigerants and federal regulations were enacted which established production and consumption allowances for HCFC refrigerants which imposed limitations on the importation of certain virgin HCFC refrigerants. Under the Act, production of certain virgin HCFC refrigerants is scheduled to be phased out during the period 2010 through 2020, and production of all virgin HCFC refrigerants is scheduled to be phased out by 2030. In October 2014, the EPA published a final rule providing further reductions in the production and consumption allowances for virgin HCFC refrigerants for the years 2015 through 2019 (the “Final Rule”). In the Final Rule, the EPA established a linear draw down for the production or importation of virgin HCFC‑22 that started at approximately 22 million pounds in 2015 and was reduced by approximately 4.5 million pounds each year ending at zero in 2020.

To the extent that the Company is unable to source sufficient quantities of refrigerants or is unable to obtain refrigerants on commercially reasonable terms or experiences a decline in demand and/or price for refrigerants sold by the Company, the Company could realize reductions in revenue from refrigerant sales, which could have a material adverse effect on its operating results and its financial position.

The Company is subject to various legal proceedings. The Company assesses the merit and potential liability associated with each of these proceedings. In addition, the Company estimates potential liability, if any, related to these matters. To the extent that these estimates are not accurate, or circumstances change in the future, the Company could realize liabilities, which could have a material adverse effect on its operating results and its financial position.

Impairment of Long-lived Assets

Impairment of Long-lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less the cost to sell.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016‑13, "Financial Instruments - Credit Losses." This ASU requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, and for interim periods therein. The Company does not expect the amended standard to have a material impact on the Company’s results of operations.

In February 2016, the FASB issued Accounting Standards Update No. 2016‑02, Leases (Topic 842) (ASU 2016‑02), as amended, which generally requires lessees to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash flows arising from leasing arrangements. In July 2018, the FASB issued ASU No. 2018‑11, Leases – Targeted Improvements, as an update to the previously-issued guidance. This update added a transition option which allows for the recognition of a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption without recasting the financial statements in periods prior to adoption. We have used the modified retrospective transition approach in ASU No. 2018‑11 and applied the new lease requirements through a cumulative-effect adjustment in the period of adoption. We elected the package of practical expedients permitted under the transition guidance, which allows us to carryforward our historical lease classification, our assessment on whether a contract is or contains a lease, and our initial direct costs for any leases that existed prior to adoption of the new standard. We also elected to combine lease and non-lease components and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of operations on a straight-line basis over the lease term. We recorded approximately $8.1 million as total right-of-use assets and total lease liabilities on our consolidated balance sheet as of January 1, 2019. The Company’s accounting for finance leases remained substantially unchanged. Disclosures relating to the amount, timing and uncertainty of cash flows arising from leases are included in Note 5.

Goodwill and intangible assets

Goodwill and intangible assets

Note 6 - Goodwill and intangible assets

Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in business combinations accounted for under the purchase method of accounting. In 2019, due to a significant selling price correction leading to unfavorable market conditions, the Company performed a quantitative test by weighting the results of an income-based valuation technique, the discounted cash flows method, and a market-based valuation technique to determine its reporting units’ fair values.

Based on the results of the impairment assessments of goodwill and other intangible assets performed in 2018, the Company concluded that it is more likely than not that the fair value of its goodwill exceeds the carrying value and that there are no impairment indicators related to intangible assets.

An impairment charge would be recognized when the carrying amount exceeds the estimated fair value of a reporting unit. These impairment evaluations use many assumptions and estimates in determining an impairment loss, including certain assumptions and estimates related to future earnings. If the Company does not achieve its earnings objectives, the assumptions and estimates underlying these impairment evaluations could be adversely affected, which could result in an asset impairment charge that would negatively impact operating results. The Company’s performance has continued to be negatively impacted by the challenging pricing environment affecting the industry and the market during 2019 resulting in an increase in inventory reserves for certain gases; however, the Company’s sales volume has increased in 2019 when compared to 2018. The Company determined as of September 30, 2019, that the year-to-date decline in revenue and operating loss, along with the decrease in the Company’s stock price during 2019 represented a triggering event which required a goodwill impairment test. Based on these indicators, the Company quantitatively evaluated its goodwill for impairment as of September 30, 2019 and determined that goodwill was not impaired.

At September 30, 2019 the Company had $47.8 million of goodwill, of which $47.0 million is attributable to the acquisition of Aspen Refrigerants, Inc. on October 10, 2017.

The Company’s other intangible assets consist of the following:

Amortization expense for the nine months ended September 30, 2019 and 2018 was $2.2 million for both periods. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. During the third quarter of 2019, the company recorded approximately $0.5 million of impairment changes with the shutdown of its Nashville and Puerto Rico facilities. No other impairment charges were recognized for the nine month period ended September 30, 2019 and for the year ended December 31, 2018.

As described in note 1, there is uncertainty around the Company's ability to comply with current and future financial covenants. Therefore, in accordance with ASC 470, the Company has reclassified its term loan debt as a current liability as of September 30, 2019.

The Company was not in compliance with the Total Leverage Ratio and the minimum liquidity covenants, calculated as of June 30, 2019 and September 30, 2019, set forth in its Term Loan Facility. At September 30, 2019, the Company's Total Leverage Ratio was 13.79:1.00 (versus a required Total Leverage Ratio of 6.40:1.00) and the Company's Liquidity (as defined in the Term Loan Facility) was $23.2 million (versus a required level of $28 million). The Company was also not in compliance with the minimum EBITDA covenant for the four quarters ended June 30, 2019 set forth in the PNC Facility and the Fixed Charge Coverage Ratio (0.40 versus 1.00) covenant for the four quarters ended September 30, 2019 set forth in the PNC Facility.

Each of the foregoing represent an Event of Default, as defined in the respective loan agreements. The occurrence of an Event of Default under both the Term Loan Facility and the PNC Facility provide the respective lenders with the right to declare all amounts under the respective agreements to be immediately due and payable and the respective lenders have the right to terminate the obligation to make loans thereunder, and furthermore allows the respective lenders to exercise any and all other remedies under the applicable agreements. The lenders under both the Term Loan Facility and the PNC Facility have delivered reservation of rights letters and the Company has been making interest payments on the PNC Facility at the default rate of interest. The Company is currently seeking a waiver and amendment from its lenders to waive prior defaults and reset the financial covenants under both the Term Loan Facility and the PNC Facility. However, there can be no assurance that the Company will be able to conclude any such waivers or amendments on acceptable terms or at all.

Bank Credit Line

On October 10, 2017, Hudson Technologies Company (“HTC”), Hudson Holdings, Inc. (“Holdings”) and Aspen Refrigerants, Inc. (“ARI”), as borrowers (collectively, the “Borrowers”), and the Company as a guarantor, became obligated under an Amended and Restated Revolving Credit and Security Agreement (the “PNC Facility”) with PNC Bank, National Association, as administrative agent, collateral agent and lender (“Agent” or “PNC”), PNC Capital Markets LLC as lead arranger and sole bookrunner, and such other lenders as may thereafter become a party to the PNC Facility.

Under the terms of the PNC Facility, the Borrowers may borrow, from time to time, up to $150 million at any time consisting of revolving loans in a maximum amount up to the lesser of $150 million and a borrowing base that is calculated based on the outstanding amount of the Borrowers’ eligible receivables and eligible inventory, as described in the PNC Facility. The PNC Facility also contains a sublimit of $15 million for swing line loans and $5 million for letters of credit.

Amounts borrowed under the PNC Facility were used by the Borrowers to consummate the acquisition of ARI and for working capital needs, certain permitted future acquisitions, and to reimburse drawings under letters of credit. At September 30, 2019, total borrowings under the PNC Facility were $15.2 million, and total additional availability was approximately $23.2 million. In addition, there was a $130,000 outstanding letter of credit at September 30, 2019.

Interest on loans under the PNC Facility is payable in arrears on the first day of each month with respect to loans bearing interest at the domestic rate (as set forth in the PNC Facility) and at the end of each interest period with respect to loans bearing interest at the Eurodollar rate (as set forth in the PNC Facility) or, for Eurodollar rate loans with an interest period in excess of three months, at the earlier of (a) each three months from the commencement of such Eurodollar rate loan or (b) the end of the interest period. Interest charges with respect to loans were initially computed on the actual principal amount of loans outstanding during the month at a rate per annum equal to (A) with respect to domestic rate loans, the sum of (i) a rate per annum equal to the higher of (1) the base commercial lending rate of PNC, (2) the federal funds open rate plus 0.5% and (3) the daily LIBOR plus 1.0%, plus (ii) between 0.50% and 1.00% depending on average quarterly undrawn availability and (B) with respect to Eurodollar rate loans, the sum of the Eurodollar rate plus between 1.50% and 2.00% depending on average quarterly undrawn availability.

Borrowers and the Company granted to the Agent, for the benefit of the lenders, a security interest in substantially all of their respective assets, including receivables, equipment, general intangibles (including intellectual property), inventory, subsidiary stock, real property, and certain other assets.

The PNC Facility contains a financial covenant requiring the Company to maintain at all times a Fixed Charge Coverage Ratio (FCCR) of not less than 1.00 to 1.00, as of the end of each trailing period of four consecutive quarters. The FCCR (as defined in the PNC Facility) is the ratio of (a) EBITDA for such period, minus unfinanced capital expenditures made during such period, minus the aggregate amount of cash taxes paid during such period, to (b) the aggregate amount of all scheduled payments of principal (excluding principal payments relating to outstanding revolving loans under the PNC Facility) and all cash payments of interest, plus cash dividends and distributions made during such period, plus payments in respect of capital lease obligations made during such period.

On December 6, 2017, the Borrowers and the Company as a guarantor, entered into a First Amendment to Amended and Restated Revolving Credit and Security Agreement (the “First Revolver Amendment”) with PNC. The First Revolver Amendment, which was entered into in connection with the syndication of the credit facility, amended the PNC Facility to allow syndicate lenders to provide certain cash management and hedging products and services to the Borrowers, and made amendments to the PNC Facility with respect to lender approval requirements of specified matters and other administrative matters.

On November 30, 2018, the Borrowers and the Company as a guarantor, entered into a Second Amendment to Amended and Restated Revolving Credit and Security Agreement, Consent and Waiver (the “Second Revolver Amendment”) with PNC Bank, National Association, as administrative agent, collateral agent and lender and the lenders thereunder.

The Second Revolver Amendment amended the Amended and Restated Revolving Credit and Security Agreement dated October 10, 2017 (as amended to date, the “PNC Facility”), to replace the existing fixed charge coverage ratio until September 30, 2019 with an EBITDA covenant requiring minimum EBITDA for the four fiscal quarters ended on the following dates: September 30, 2018 - $9,240,000; December 31, 2018 - $9,428,000; March 31, 2019 - $9,270,000; June 30, 2019 - $14,195,000. The minimum fixed charge coverage ratio of 1.00:1.00 recommenced for the quarter ended September 30, 2019.

The Second Revolver Amendment also increased the applicable interest rate margin to 3% for Eurodollar Rate Loans (as defined in the PNC Facility) and 2% for Domestic Rate Loans (as defined in the PNC Facility) through September 30, 2019, with applicable margins thereafter of between 2.5% and 3% for Eurodollar Rate Loans and 1.5% and 2% for Domestic Rate Loans based on the applicable fixed charge coverage ratio. In connection with the Second Revolver Amendment, the Borrowers also paid the Agent a waiver and amendment fee of $250,000.

On April 17, 2019, the Borrowers, the Company as a guarantor, and ten new subsidiaries of the Borrowers (the “New Subsidiaries”), entered into a Third Amendment and Joinder to Amended and Restated Revolving Credit and Security Agreement and Waiver (the “Third Revolver Amendment”) with PNC Bank, National Association, as administrative agent, collateral agent and lender and the lenders thereunder. Pursuant to the Third Amendment, the New Subsidiaries were added as guarantors under the PNC Facility.

The Company evaluated the First, Second and Third Revolver Amendments in accordance with the provisions of ASC 470 to determine if the Amendments were a modification or an extinguishment of debt and concluded that amendments were a modification of the original term loan agreement for accounting purposes. As a result, the Company capitalized an additional $250,000 of deferred financing costs in connection with the Second Revolver Amendment, which are being amortized over the remaining term.

The PNC Facility also contains customary non-financial covenants relating to the Company and the Borrowers, including limitations on Borrowers’ ability to pay dividends on common stock or preferred stock, and also includes certain events of default, including payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to other obligations, events of bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of control.

The commitments under the PNC Facility will expire and the full outstanding principal amount of the loans, together with accrued and unpaid interest, are due and payable in full on October 10, 2022, unless the commitments are terminated and the outstanding principal amount of the loans are accelerated sooner following an event of default.

In connection with the closing of the PNC Facility, the Company also entered into an Amended and Restated Guaranty and Suretyship Agreement, dated as of October 10, 2017 (the “Revolver Guarantee”), pursuant to which the Company affirmed its unconditional guarantee of the payment and performance of all obligations owing by Borrowers to PNC, as Agent for the benefit of the revolving lenders.

Term Loan Facility

On October 10, 2017, HTC, Holdings, and ARI, as borrowers, and the Company, as guarantor, became obligated under a Term Loan Credit and Security Agreement (the “Term Loan Facility”) with U.S. Bank National Association, as administrative agent and collateral agent (“Term Loan Agent”) and funds advised by FS Investments and such other lenders as may thereafter become a party to the Term Loan Facility (the “Term Loan Lenders”).

Under the terms of the Term Loan Facility, the Borrowers immediately borrowed $105 million pursuant to a term loan (the “Initial Term Loan”) and could borrow up to an additional $25 million for a period of eighteen months after closing to fund additional permitted acquisitions (the “Delayed Draw Commitment”, and together with the Initial Term Loan, the “Term Loans”).

On June 29, 2018, HTC, Holdings and ARI, as borrowers, and the Company as a guarantor, entered into a Limited Waiver and First Amendment to Term Loan Credit and Security Agreement and Other Documents (the “First Amendment”) with U.S. Bank National Association, as collateral agent and administrative agent, and the various lenders thereunder. The First Amendment terminated the Delayed Draw Commitment and provided an interim waiver with respect to compliance with the existing total leverage ratio ("TLR”) covenant at June 30, 2018.

The Term Loans mature on October 10, 2023. Principal payments on the Term Loans are required on a quarterly basis, commencing with the quarter ended March 31, 2018, in the amount of 1% per annum of the original principal of the outstanding Term Loans. Commencing with the fiscal year ending December 31, 2018, the Term Loan Facility also requires annual principal payments of up to 50% of Excess Cash Flow (as defined in the Term Loan Facility) if the Company’s Total Leverage Ratio (as defined in the Term Loan Facility) for the applicable year is greater than 2.75 to 1.00. The Term Loan Facility also requires mandatory prepayments of the Term Loans in the event of certain asset dispositions, debt issuances, and casualty and condemnation events. The Term Loans may be prepaid at the option of the Borrowers at par in an amount up to $30 million. Additional prepayments are permitted after the first anniversary of the closing date and were originally subject to a prepayment premium of 3% in year two, 1% in year three and zero in year four and thereafter.

Interest on the Term Loans is generally payable on the earlier of the last day of the interest period applicable to such Eurodollar rate loan and the last day of the Term Loan Facility, as applicable. Interest was originally payable at the rate per annum of the Eurodollar Rate (as defined in the Term Loan Facility) plus 7.25%. The Borrowers have the option of paying 3.00% interest per annum in kind by adding such amount to the principal of the Term Loans during no more than five fiscal quarters during the term of the Term Loan Facility.

Borrowers and the Company granted to the Term Loan Agent, for the benefit of the Term Loan Lenders, a security interest in substantially all of their respective assets, including receivables, equipment, general intangibles (including intellectual property), inventory, subsidiary stock, real property, and certain other assets.

The Term Loan Facility originally contained a financial covenant requiring the Company to maintain a Total Leverage Ratio (TLR) of not greater than 4.75 to 1.00, tested as of the last day of the fiscal quarter. The Term Loan Facility was amended on August 14, 2018, including a waiver of the TLR covenant at June 30, 2018, as described below. The TLR (as defined in the Term Loan Facility) is the ratio of (a) funded debt as of such day to (b) EBITDA for the four consecutive fiscal quarters ending on the last day of such fiscal quarter. Funded debt (as defined in the Term Loan Facility) includes amounts borrowed under the PNC Facility and the Term Loan Facility as well as capitalized lease obligations and other indebtedness for borrowed money maturing more than one year from the date of creation thereof. As of September 30, 2019 and December 31, 2018, the TLR was approximately 13.79 to 1 and 11.82 to 1, respectively.

The Term Loan Facility also contains customary non-financial covenants relating to the Company and the Borrowers, including limitations on their ability to pay dividends on common stock or preferred stock, and also includes certain events of default, including payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to other obligations, events of bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of control.

In connection with the closing of the Term Loan Facility, the Company also entered into a Guaranty and Suretyship Agreement, dated as of October 10, 2017 (the “Term Loan Guarantee”), pursuant to which the Company affirmed its unconditional guarantee of the payment and performance of all obligations owing by Borrowers to Term Loan Agent, as agent for the benefit of the Term Loan Lenders.

The Term Loan Agent and the Agent have entered into an intercreditor agreement governing the relative priority of their security interests granted by the Borrowers and the Guarantor in the collateral, providing that the Agent shall have a first priority security interest in the accounts receivable, inventory, deposit accounts and certain other assets (the “Revolving Credit Priority Collateral”) and the Term Loan Agent shall have a first priority security interest in the equipment, real property, capital stock of subsidiaries and certain other assets (the “Term Loan Priority Collateral”).

On August 14, 2018, HTC, Holdings and ARI, as borrowers, and the Company as a guarantor, entered into a Waiver and Second Amendment to Term Loan Credit and Security Agreement (the “Second Amendment”) with U.S. Bank National Association, as collateral agent and administrative agent, and the various lenders thereunder. The Second Amendment superseded interim waivers and amended the Term Loan Facility, to waive compliance with the existing TLR covenant at June 30, 2018.

In addition, the Second Amendment also: (i) increases the interest rate by 300 basis points effective July 1, 2018; (ii) waives the existing prepayment premium in the Term Loan Facility in the event the term loan is repaid in full prior to March 31, 2020; (iii) adds an exit fee equal to three percent (3.00%) of the outstanding principal balance of the term loans on the date of the Second Amendment (provided, that payment of the exit fee is waived in the event that the term loan is repaid in full prior to January 1, 2020, and provided further that the exit fee is reduced to one-and-one-half percent (1.50%) in the event that the term loan is repaid in full on or after January 1, 2020 but prior to March 31, 2020); (iv) restricted acquisitions and other equity investments prior to September 30, 2018; and (v) required payment of a one-time waiver fee equal to one percent (1.00%) of the outstanding term loans.

On November 30, 2018, the Borrowers, and the Company as a guarantor, entered into a Waiver and Third Amendment to Term Loan Credit and Security Agreement (the “Third Amendment”) with U.S. Bank National Association, as collateral agent and administrative agent, and the various lenders thereunder.

The Third Amendment superseded interim waivers and amended the Term Loan Facility to reset the maximum Total Leverage Ratio covenant contained in the Term Loan Facility at the indicated dates as follows: (i) June 30, 2018 - 10.15:1.00; (ii) September 30, 2018 - 12.45:1.00; (iii) December 31, 2018 – 12.75:1.00; (iv) March 31, 2019 – 12.95:1.00; (v) June 30, 2019 – 8.25:1.00; September 30, 2019 – 6.40:1.00; (vi) December 31, 2019 – 5:70:1.00; and (vii) March 31, 2020 and each fiscal quarter thereafter – 4:75:1.00.

The Third Amendment increased the scheduled quarterly principal repayments to $525,000 effective December 31, 2018. In addition the Third Amendment requires a further repayment of principal on or before November 14, 2019 in an amount equal to (x) 100% of Excess Cash Flow (as defined in the Term Loan Facility) for the four fiscal quarter period ended September 30, 2019 if after giving effect to the payment thereof, the Borrowers have minimum aggregate Undrawn Availability (as defined in the Term Loan Facility) of at least $35,000,000, (y) 50% of Excess Cash Flow for the four fiscal quarter period ended September 30, 2019 if after giving effect to the payment thereof, the Borrowers have minimum aggregate Undrawn Availability of at least $15,000,000 but less than $35,000,000, and (z) 0% of Excess Cash Flow for the four fiscal quarter period ended September 30, 2019 if after giving effect to the payment thereof, the Borrowers have minimum aggregate Undrawn Availability less than $15,000,000, with any such payment subject to reduction by the amount of any voluntary prepayments made following the date of the Third Amendment. Any voluntary prepayments will not be subject to the prepayment premium or make-whole provisions of the Term Loan Facility. The Third Amendment also adds a minimum liquidity requirement (consisting of cash plus undrawn availability on the Borrowers’ revolving loan facility) of $28 million, measured monthly.

The Third Amendment also amended the exit fee payable to the term loan lenders to five percent (5.00%) of the outstanding principal balance of the term loans on November 30, 2018 (the “Exit Fee”), which Exit Fee shall be payable in full in cash upon the earlier to occur of (x) repayment in full of the term loans, or (y) any acceleration of the term loans. The Exit Fee will be reduced by one-tenth of one percent (0.10%) for every $1,000,000 in voluntary prepayments made prior to January 1, 2020; provided, that, in no event shall the Exit Fee be reduced below three percent (3.00%) as a result of any such prepayments, (ii) payment of the Exit Fee shall be waived in the event that repayment in full of the term loans occurs prior to January 1, 2020, and (iii) the Exit Fee shall be reduced by an amount equal to fifty percent (50%) of the amount that would otherwise payable in the event that repayment in full occurs on or after January 1, 2020 but prior to March 31, 2020.

On April 17, 2019, the Borrowers and the Company as a guarantor, and ten new subsidiaries of the Borrowers (the “New Subsidiaries”), entered into a Joinder to Term Loan Credit and Security Agreement and Other Documents (the “Joinder”) with U.S. Bank National Association, as collateral agent and administrative agent, and the various lenders thereunder. Pursuant to the Joinder, the New Subsidiaries were added as guarantors under the Term Loan Facility.

The Company evaluated the First, Second and Third Amendments in accordance with the provisions of ASC 470 to determine if the Amendments were a modification or an extinguishment of debt and concluded that the amendments were a modification of the original term loan agreement for accounting purposes. As a result, in 2018 the Company capitalized an additional $1.0 million of deferred financing costs in connection with the Second Amendment, which are being amortized over the remaining term.

Vehicle and Equipment Loans

The Company has entered into various vehicle and equipment loans. These loans are payable in 60 monthly payments through March 2020 and bear interest ranging from 0.0% to 8.3%.

Capital Lease Obligations

The Company rents certain equipment with a net book value of approximately $0.03 million at September 30, 2019 under leases which have been classified as capital leases. Scheduled future minimum lease payments under capital leases, net of interest, are as follows:

Twelve Month Period Ending September 30,	Amount
(in thousands)
‑2020	$	14
‑2021		5
‑2022		0
‑2023		0
‑2024		0
Subtotal		19
Less interest expense		(1)
Total	$	18

Scheduled maturities of the Company’s long-term debt and capital lease obligations are as follows:

Twelve Month Period Ending September 30,	Amount
(in thousands)
‑2020	$	2,114
‑2021		2,105
‑2022		2,100
‑2023		2,100
‑2024		93,712
Total	$	102,131

The above schedule reflects the scheduled maturities related to the term loan, which has been reclassified to short-term due to the uncertainty around the Company's ability to comply with current and future financial covenants.

Fair Value

Fair Value

Note 2 - Fair Value

ASC Subtopic 820‑10 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company often utilizes certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and/or the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market-corroborated, or generally unobservable inputs. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Based upon observable inputs used in the valuation techniques, the Company is required to provide information according to the fair value hierarchy.

The fair value hierarchy ranks the quality and reliability of the information used to determine fair values into three broad levels as follows:

Level 1: Valuations for assets and liabilities traded in active markets from readily available pricing sources for market transactions involving identical assets or liabilities.

Level 2: Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained from third-party pricing services for identical or similar assets or liabilities.

Level 3: Valuations for assets and liabilities include certain unobservable inputs in the assumptions and projections used in determining the fair value assigned to such assets or liabilities.

In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

Note 5‑ Leases

The Company has various lease agreements with terms up to 11 years, including leases of buildings and various equipment. Some leases include options to purchase, terminate or extend for one or more years. These options are included in the lease term when it is reasonably certain that the option will be exercised.

At inception, the Company determines if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. Some of the Company’s lease arrangements contain lease components (e.g. minimum rent payments) and non-lease components (e.g. common area maintenance, charges, utilities and property taxes). The Company elected the package of practical expedients permitted under the transition guidance, which allows us to carry forward our historical lease classification, our assessment on whether a contract contains a lease, and our initial direct costs for any leases that existed prior to the adoption of the new standard. We also elected to combine lease and non-lease components and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of operations on a straight line basis over the lease term. The Company’s lease agreements do not contain any material residual value, guarantees or material restrictive covenants.

Operating leases are included in Right of use asset, Accrued expenses and other current liabilities, and Long-term lease liabilities on the consolidated balance sheets. These assets and liabilities are recognized at the commencement date based on the present value of remaining lease payments over the lease term using the Company’s secured incremental borrowing rates or implicit rates, when readily determinable. Short-term operating leases, which have an initial term of 12 months or less, are not recorded on the balance sheet. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Variable lease expense is recognized in the period in which the obligation for those payments is incurred. The Company has four leases with renewal options and they are not reasonably certain to be exercised.

Lease expense is included in selling, general and administrative expenses on the consolidated statements of operations and is reported net of lease income. Lease income is not material to the results of operations for the quarter and nine months  ended September 30, 2019.

The following table presents information about the amount, timing and uncertainty of cash flows arising from the Company’s operating leases as of September 30, 2019.
