Accounting Policies [Abstract] |
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 products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems, including (i) refrigerant sales, (ii) refrigerant management services consisting primarily of reclamation of refrigerants and (iii) RefrigerantSide® Services performed at a customer's site, consisting of system decontamination to remove moisture, oils and other contaminants. In addition, RefrigerantSide® Services include predictive and diagnostic services for industrial and commercial refrigeration applications, which are designed to predict potential catastrophic problems and identify inefficiencies in an operating system. 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®, Chill Smart®, Fluid Chemistry®, and Performance Optimization are predictive and diagnostic service offerings. As a component of the Company’s products and services, the Company also participates in the generation of carbon offset projects. The Company operates principally through its wholly-owned subsidiary, 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. In preparing the accompanying consolidated financial statements, and in accordance with ASC855-10 “Subsequent Events”, the Company’s management has evaluated subsequent events through the date that the financial statements were filed. 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. and Hudson Technologies Company. The Company does not present a statement of comprehensive income as its comprehensive income is not materially different than its net income.
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 December 31, 2014 and December 31, 2013, because of the relatively short maturity of these instruments. The carrying value of short and long-term debt approximates fair value, based upon quoted market rates of similar debt issues, as of December 31, 2014 and December 31, 2013.
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 year ended December 31, 2014, two customers each accounted for 10% or more of the Company’s revenues and, in the aggregate these two customers accounted for 25% of the Company’s revenues. At December 31, 2014, there were $688,000 in outstanding receivables from these customers. For the year ended December 31, 2013, two customers each accounted for 10% or more of the Company’s revenues and, in the aggregate these two customers accounted for 23% of the Company’s revenues. At December 31, 2013, there were $344,000 in outstanding receivables from these customers. 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 market. 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 market adjustment, the impact of which is reflected in cost of sales on the Consolidated Statements of Operations. Any such adjustment is 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.
Revenues and Cost of Sales | Revenues and Cost of Sales Revenues are recorded upon completion of service or product shipment and passage of title to customers in accordance with contractual terms. The Company evaluates each sale to ensure collectability. In addition, each sale is based on an arrangement with the customer and the sales price to the customer is fixed. License fees are recognized over the period of the license based on the respective performance measurements associated with the license. Royalty revenues are recognized when earned. 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. 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 refrigerant and reclamation sales and RefrigerantSide® Services, including license and royalty revenues. The revenues for each of these lines are as follows:
Years Ended December 31, |  | 2014 |  | 2013 |
(in thousands) |  |  |  |  |  |  |
Refrigerant and reclamation sales |  | $ | 50,460 |  | $ | 54,293 |
RefrigerantSide® Services |  |  | 5,350 |  |  | 4,341 |
Total |  | $ | 55,810 |  | $ | 58,634 |
Income Taxes | Income Taxes The Company utilizes the asset and liability method for recording deferred income taxes, which provides for the establishment of deferred tax asset or liability accounts based on the difference between tax and financial reporting bases of certain 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 is expected to recognize future taxable income. The Company assesses the recoverability of its deferred tax assets based on its expectation that it will recognize future taxable income and adjusts its valuation allowance accordingly. As of December 31, 2014 and 2013, the net deferred tax asset was $6,428,000 and $5,570,000, respectively. Certain states either do not allow or limit NOLs and as such the Company will be liable for certain state taxes. To the extent that the Company utilizes its NOLs, it will not pay tax on such income but may be subject to the federal alternative minimum tax. In addition, to the extent that the Company’s net income, if any, exceeds the annual NOL limitation it will pay income taxes based on existing statutory rates. Moreover, as a result of a “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. Approximately $8,000,000 of the Company’s $16,000,000 of NOLs are subject to annual limitations of $1,300,000. As a result of an Internal Revenue Service audit, the 2011 and prior federal tax years have been closed. The Company operates in many states throughout the United States and, as of December 31, 2014, the various states’ statutes of limitations remain open for tax years subsequent to 2008. The Company recognizes interest and penalties, if any, relating to income taxes as a component of the provision for income taxes. The IRS recently initiated an examination of the Company’s federal income tax returns for the fiscal years 2012 and 2013. The Company does not expect the results of this examination to have a material effect on the Company’s financial statements. 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 December 31, 2014 and 2013, the Company had no uncertain tax positions.
Income per Common and Equivalent Shares | Income per Common and Equivalent Shares If dilutive, common equivalent shares (common shares assuming exercise of options and warrants) utilizing the treasury stock method are considered in the presentation of diluted earnings per share. The reconciliation of shares used to determine net income per share is as follows (dollars in thousands, unaudited):
|  | Years ended December 31, |
|  | 2014 |  | 2013 |
Net loss |  | $ | (720) |  | $ | (5,842) |
Weighted average number of shares - basic |  |  | 29,122,746 |  |  | 24,826,101 |
Shares underlying warrants |  |  | 0 |  |  | 0 |
Shares underlying options |  |  | 0 |  |  | 0 |
Weighted average number of shares outstanding - diluted |  |  | 29,122,746 |  |  | 24,826,101 |
During the year ended December 31, 2014 and 2013, certain options and warrants aggregating 4,449,624 and 3,760,161 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 management to make estimates and assumptions that affect reported amounts of certain assets and liabilities, the disclosure of contingent assets and liabilities, and the results of operations during the reporting period. Actual results could differ from these estimates. 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 estimations. 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. As a result of litigation, the federal regulations implementing the January 2010 phase down schedule were vacated, and in April 2013, the Environmental Protection Agency (“EPA”) published a final rule providing for the production or importation of 63 million and 51 million pounds of HCFC-22 in 2013 and 2014, respectively. The Company believes that the production permitted by the final rule created an oversupply of HCFC-22 during the 2013 cooling season. The Company believes that this oversupply resulted in a reduction in the market price of HCFC-22 during 2013, which resulted in the Company having to record a lower of cost or market adjustment in the amount of $14,700,000 for the year ended December 31, 2013 (the “LCM”). On October 16, 2014, the Administrator of the EPA signed 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 has established a linear draw down for the production or importation of virgin HCFC-22 that will start at approximately 22 million pounds in 2015 and reduce by approximately 4.5 million pounds each year and end 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 April 2014, the FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” ASU 2014-08 changes the requirements for reporting discontinued operations so that only those disposals of components of an entity that represent a strategic shift that has (or will have) a major effect on an entity’s operations and financial results will be reported as discontinued operations in the financial statements when the component of an entity or group of components of an entity meets the criteria to be classified as held for sale, is disposed of by sale, or is disposed of other than by sale (for example, by abandonment or in a distribution to owners in a spinoff). Examples of a strategic shift that has (or will have) a major effect on an entity’s operations and financial results could include a disposal of a major geographical area, a major line of business, a major equity method investment, or other major parts of an entity. A business or nonprofit activity that, on acquisition, meets the criteria to be classified as held for sale also is a discontinued operation. The amendments in ASU 2014-08 require an entity to present, for each comparative period, the assets and liabilities of a disposal group that includes a discontinued operation separately in the asset and liability sections, respectively, of the statement of financial position and also require additional disclosures about discontinued operations. Public business entities should apply the amendments in ASU 2014-08 prospectively to both disposals (or classifications as held for sale) of components of an entity and businesses that, on acquisition, are classified as held for sale that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The adoption of ASU 2014-08 will not have a material impact on our results of operations or our financial position. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The guidance also specifies the accounting for some costs to obtain or fulfill a contract with a customer. The new standard also will result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively (for example, service revenue and contract modifications) and improve guidance for multiple-element arrangements. For a public entity, the amendments in this Update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. An entity should apply the amendments in ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application. We are currently evaluating the effects of ASU 2014-09 and therefore cannot estimate the effects, if any, on historical or future revenue recognition at this time.
