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 operates principally through its wholly-owned subsidiary, Hudson Technologies Company, and Aspen Refrigerants (“Aspen” or “ARI”), a division of Hudson Technologies Company. Unless the context requires otherwise, references to the “Company”, “Hudson”, “we", “us”, “our”, or similar pronouns refer to Hudson Technologies, Inc. and its subsidiaries. The Company is a leading provider of sustainable refrigerant products and services to the Heating Ventilation Air Conditioning and Refrigeration (“HVACR”) industry. For nearly three decades, we have demonstrated our commitment to our customers and the environment by becoming one of the first in the United States and largest refrigerant reclaimers through multimillion dollar investments in the plants and advanced separation technology required to recover a wide variety of refrigerants and restoring them to Air-Conditioning, Heating, and Refrigeration Institute (“AHRI”) standard for reuse as certified EMERALD Refrigerants™. 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. 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. During the year ended December 31, 2020 and continuing through the six months ended June 30, 2021, the effects of a novel strain of coronavirus ("COVID-19") pandemic and the related actions by governments around the world to attempt to contain the spread of the virus have materially impacted the global economy. While it is difficult to predict the full scale of the ongoing impact of the COVID-19 outbreak and business disruption, the Company has been taking actions to address the impact of the pandemic, such as working closely with our customers, reducing our expenses and monitoring liquidity. The impact of the pandemic and the corresponding actions were reflected into our judgments, assumptions and estimates to prepare the financial statements. As of the date of this filing, there has been no material impact on our ability to procure or distribute our products and services. However, if the duration of the COVID-19 pandemic is longer and the operational impact is greater than estimated, the judgments, assumptions and estimates will be updated and could result in different results in the future. 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, 2020. Operating results for the six-month period ended June 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. 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, which have been prepared in accordance with accounting principles generally accepted in the United States, 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. and Hudson Technologies Company. The Company does not present a statement of comprehensive income (loss) as its comprehensive income (loss) is the same as its net income (loss). Fair Value of Financial Instruments The carrying values of financial instruments including cash, trade accounts receivable and accounts payable approximate fair value at June 30, 2021 and December 31, 2020, 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 June 30, 2021 and December 31, 2020. See Note 2 for further details. 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. At June 30, 2021, the Company had trade receivables of $35.1 million, allowance for doubtful accounts of $1.8 million, resulting in net accounts receivable of $33.3 million. For the six month period ended June 30, 2021 there was one customer accounting for 10% of the Company’s revenues and at June 30, 2021 there were $2.2 million of accounts receivable from this customer. For the six month period ended June 30, 2020 there was one customer accounting for 12% of the Company’s revenues and at June 30, 2020 there were $2.0 million of accounts receivable from this customer. 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. Goodwill is tested for impairment at the reporting unit level. The Company has one reporting unit at June 30, 2021. 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 records 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. There were no goodwill impairment losses recognized in 2020 or the six months ended June 30, 2021. Cylinder Deposit Liability The cylinder deposit liability, which is included in Accrued expenses and other current liabilities on the Company’s Balance Sheet, represents the amount due to customers for the return of refillable cylinders. ARI charges its customers cylinder deposits upon the shipment of refrigerant gases that are contained in refillable cylinders. The amount charged to the customer by ARI approximates the cost of a new cylinder of the same size. Upon return of a cylinder, this liability is reduced. Revenues and Cost of Sales 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 to which 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 which has been exercised, 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. 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. The Company elected to implement ASC 606-10-25-18B, whereby the Company accounts 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. 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. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted in response to the COVID-19 pandemic. The CARES Act, among other things, permits NOL carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. Further, starting in 2021, the 100% NOL utilization reverts back to the pre-CARES Act limitation of 80% of taxable income. The Company has evaluated its options under the carryback provision and filed a claim for refund, resulting in a cash benefit. Further, the CARES Act accelerates the refund of the alternative minimum tax credits to allow a full refund of any remaining credit amount in taxable years beginning in 2019. The credits were originally fully refundable in taxable years beginning in 2021. As a result, the Company has recorded a preliminary $47,000 tax benefit related to the alternative minimum tax refund in the quarter ended March 31, 2020 and an additional $380,000 in the quarter ended June 30, 2020. Finally, the CARES Act contains modifications on the limitation of business interest for tax years beginning in 2019 and 2020. As of June 30, 2021, the Company had NOLs of approximately $38.5 million, of which none have an expiration date. As of June 30, 2021, the Company had state tax NOLs of approximately $31.3 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 our assessment as of December 31, 2018, 2019, 2020 and June 30, 2021, 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 2018, and due to additional losses, increased the valuation allowance through 2019, 2020 and June 30, 2021, with an ending balance of $14.0 million as of June 30, 2021. 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 June 30, 2021 and December 31, 2020, 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 loss per share is as follows (dollars in thousands, unaudited): ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Three Months |  | Six Months
​ | ​ | ended June 30, | ​ | ended June 30,
​ |  | 2021 |  | 2020 |  | 2021 |  | 2020
Net income (loss) | ​ | $ | 11,277 | ​ | $ | 2,386 | ​ | $ | 10,201 | ​ | $ | (499)

​ During the three month periods ended June 30, 2021 and 2020, certain options aggregating 30,843 and 5,282,377 shares, respectively, have been excluded from the calculation of diluted shares, due to the fact that their effect would be anti-dilutive. During the six month periods ended June 30, 2021 and 2020, certain options aggregating 199,694 and 7,042,377 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 including potential impact of COVID-19 uncertainties. 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, goodwill and valuation allowance for the deferred tax assets relating to its NOLs and commitments and contingencies. With respect to trade 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 its business could affect its 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. 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, Measurement of Credit Losses on Financial Instruments, which revises guidance for the accounting for credit losses on financial instruments within its scope, and in November 2018, issued ASU No. 2018-19 and in April 2019, issued ASU No. 2019-04 and in May 2019, issued ASU No. 2019-05, and in November 2019, issued ASU No. 2019-11, which each amended the standard. The new standard introduces an approach, based on expected losses, to estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale debt securities. The new approach to estimating credit losses (referred to as the current expected credit losses model) applies to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities, net investments in leases and off-balance-sheet credit exposures. This ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, with early adoption permitted. Entities are required to apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The Company is still evaluating the impact of this ASU. In March 2020, the FASB issued ASU 2020-04, which provides relief from accounting analysis and impacts that may otherwise be required for modifications to agreements necessitated by reference rate reform. It also provides optional expedients to enable the continuance of hedge accounting where certain hedging relationships are impacted by reference rate reform. This optional guidance is effective immediately, and available to be used through December 31, 2022. We are assessing the impact that reference rate reform and the related adoption of this guidance will have on our financial statements. In August 2020, the FASB issued ASU 2020-06, "Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity", which is intended to simplify the accounting for convertible instruments by removing certain separation models in Subtopic 470-20, Debt-Debt with Conversion and Other Options, for convertible instruments. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2021, with early adoption permitted. We are currently in the process of evaluating the effects of the provisions of ASU 2020-06 on our financial statements.
