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 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.

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 the quarterly report should be read in conjunction with the Company’s audited financial statements and related notes thereto for the year ended December 31, 2013. Operating results for the six month period ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.

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. and Hudson Technologies Company.

Fair Value of Financial Instruments

The carrying values of financial instruments including trade accounts receivable and accounts payable approximate fair value at June 30, 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 June 30, 2014 and December 31, 2013.

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 receivables 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 six month period ended June 30, 2014, two customers each accounted for 10% or more of the Company’s revenues and, in the aggregate these two customers accounted for 28% of the Company’s revenues. At June 30, 2014, there were $1,230,000 in outstanding receivables from these customers.

For the six month period ended June 30, 2013, two customers each accounted for 10% or more of the Company’s revenues and, in the aggregate these two customers accounted for 29% of the Company’s revenues. At June 30, 2013, there were $1,842,000 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

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 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 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 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 buyer 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:

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 June 30, 2014 and December 31, 2013, the net deferred tax asset was $5,294,000 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 $10,600,000 of the Company’s $16,000,000 of NOLs are subject to annual limitations of $1,300,000.

The Company has a current income tax receivable of $1,699,000 at June 30, 2014. This receivable is primarily related to the pre-tax loss for the year ended December 31, 2013.

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 June 30, 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 closed an examination of the Company’s federal income tax return for the fiscal year 2011. There were no changes to the 2011 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 June 30, 2014 and December 31, 2013, the Company had no uncertain tax positions.

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):

During the three month periods ended June 30, 2014 and 2013, certain options and warrants aggregating 80,843 and 50,000 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, 2014 and 2013, certain options and warrants aggregating 80,843 and 50,000 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 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 and 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 December 2009, the Environmental Protection Agency (“EPA”) issued a final rule (the “2009 Rule”) which limited the total pounds of virgin HCFC refrigerants that could be produced and imported for the years 2010 through 2014 to levels which, based upon the EPA’s estimates, would require as much as 20% of the service demand for existing equipment to be met by reclaimed or recycled HCFC refrigerants. As a result of litigation, the 2009 Rule was vacated, and in April 2013, the EPA issued a final rule (the “April 2013 Rule”) providing for further reductions in the production and importation of HCFC refrigerants in the years 2013 and 2014 when compared to the reductions originally established in the 2009 Rule. In December 2013, a proposed rule was issued by the EPA to address production and consumption allowances for HCFC refrigerants for the years 2015 through 2019. In the proposed rule, the EPA discusses several alternatives for the phase down of HCFC-22 during the years 2015 through 2019, and identifies a preferred approach that would implement a linear draw down for the production or importation of HCFC-22 that would start at 30 million pounds in 2015 and reduce by approximately 6 million pounds each year and end at zero in 2020. A final rule to address production and consumption allowances for the years 2015 through 2019 has not yet been issued by the EPA. The Company expects that a final rule establishing the actual number of pounds for the years 2015 through 2019 will be issued late in 2014.

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 March 2013, the FASB issued ASU No. 2013-05, which amends the guidance in ASC 830, “Foreign Currency Matters”. ASU No. 2013-05 addresses the accounting for the cumulative translation adjustment (“CTA”) when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. This amended guidance is to be applied prospectively and is effective for the Company beginning on January 1, 2014. The implementation of the amended accounting guidance did not have a material impact on our consolidated financial position or results of operations.

In July 2013, the FASB issued ASU 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." ASU 2013-11 requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The amendments in this Update are effective for fiscal years (and interim periods within those years) beginning after December 15, 2013. The adoption of ASU 2013-11 did not have a material impact on our results of operations or our financial position.

Share-Based Compensation [Abstract]	'
Share-based Compensation	'
	Note 2 - Share-based Compensation

	Share-based compensation represents the cost related to share-based awards, typically stock options, 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 six month periods ended June 30, 2014 and 2013, the share-based compensation expense of $18,000 and $33,000, respectively, is reflected in general and administrative expenses in the consolidated income statements.

	Share-based awards have historically been stock options 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 June 30, 2014, the Plans authorized the issuance of stock options to purchase 5,500,000 shares of the Company’s common stock and, as of June 30, 2014 there were 2,511,733 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 generally vested from immediately to two years from the grant date and have had a contractual term ranging from five to ten years.

	For the six month periods ended June 30, 2014 and 2013, the Company issued options to purchase 10,000 shares and 50,000 shares, respectively. As of June 30, 2014, there was $79,000 of unrecognized compensation cost related to non-vested previously granted option awards.

	Effective July 25, 1997, the Company adopted its 1997 Employee Stock Option Plan, which was amended on August 19, 1999, (“1997 Plan”) pursuant to which 2,000,000 shares of common stock were reserved for issuance upon the exercise of options designated as either (i) incentive stock options (“ISOs”) under the Internal Revenue Code of 1986, as amended (the ”Code”), or (ii) nonqualified options. ISOs could be granted under the 1997 Plan to employees and officers of the Company. Non-qualified options could be granted to consultants, directors (whether or not they are employees), employees or officers of the Company. Stock appreciation rights could also be issued in tandem with stock options. Effective June 11, 2007, the Company’s ability to grant options or stock appreciation rights under the 1997 Plan expired.

	Effective September 10, 2004, the Company adopted its 2004 Stock Incentive Plan (“2004 Plan”) pursuant to which 2,500,000 shares of common stock were reserved for issuance upon the exercise of options, designated as either (i) ISOs under the Code, or (ii) nonqualified options, restricted stock, deferred stock or other stock-based awards. ISOs may be granted under the 2004 Plan to employees and officers of the Company. Non qualified options, restricted 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 2004 Plan is sooner terminated, the ability to grant options or other awards under the 2004 Plan will expire on September 10, 2014.

	ISOs granted under the 2004 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 2004 Plan may not be granted at a price less than the fair market value of the common stock. Options granted under the 2004 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).

	Effective August 27, 2008, the Company adopted its 2008 Stock Incentive Plan (“2008 Plan”) pursuant to which 3,000,000 shares of common stock were reserved for issuance upon the exercise of options, designated as either (i) ISOs under the Code, or (ii) nonqualified options, restricted stock, deferred stock or other stock-based awards. ISOs may be granted under the 2008 Plan to employees and officers of the Company. Non qualified options, restricted 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 2008 Plan is sooner terminated, the ability to grant options or other awards under the 2008 Plan will expire on August 27, 2018.

	ISOs granted under the 2008 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 2008 Plan may not be granted at a price less than the fair market value of the common stock. Options granted under the 2008 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).

	All stock options have been granted to employees and non-employees at exercise prices equal to or in excess of the market value 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 with the following weighted-average assumptions:

	Note 3 - Debt

	Bank Credit Line

	On June 22, 2012, a subsidiary of Hudson entered into a Revolving Credit, Term Loan and Security Agreement (the “PNC Facility”) with PNC Bank, National Association, as agent (“Agent” or “PNC”), and such other lenders as may thereafter become a party to the PNC Facility. Under the terms of the PNC Facility, Hudson could initially borrow up to $27,000,000 consisting of a term loan in the principal amount of $4,000,000 and revolving loans in a maximum amount up to the lesser of $23,000,000 and a borrowing base that is calculated based on the outstanding amount of Hudson’s eligible receivables and eligible inventory, as described in the PNC Facility. On February 15, 2013, the PNC Facility was amended. As a result of this amendment, Hudson may borrow up to a maximum of $40,000,000 consisting of a term loan in the principal amount of $4,000,000 and revolving loans in a maximum amount up to $36,000,000. Amounts borrowed under the PNC Facility may be used by Hudson for working capital needs and to reimburse drawings under letters of credit. Fees and expenses relating to the creation of the PNC Facility of approximately $125,000 are being amortized over the life of the loan. At June 30, 2014, total borrowings under the PNC Facility were none, and there was $24,000,000 available to borrow under the revolving line of credit. The effective interest rate under the PNC Facility was 3.0% at June 30, 2014.

	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 are 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 .5% and (3) the daily LIBOR plus 1%, plus (ii) .5% and (B) with respect to Eurodollar rate loans, the sum of the Eurodollar rate plus 2.75%.

	Hudson granted to PNC, for itself, and as agent for such other lenders as may thereafter become a lender under the PNC Facility, a security interest in Hudson’s receivables, intellectual property, general intangibles, inventory and certain other assets.

	The PNC Facility contains certain financial and non-financial covenants relating to Hudson, including limitations on Hudson’s 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 PNC Facility contains a financial covenant to maintain at all times a Fixed Charge Coverage Ratio of not less than 1.10 to 1.00, tested quarterly on a rolling twelve month basis. Fixed Charge Coverage Ratio is defined in the PNC Facility, with respect to any fiscal period, as the ratio of (a) EBITDA of Hudson for such period, minus unfinanced capital expenditures (as defined in the PNC Facility) made by Hudson during such period, minus the aggregate amount of cash taxes paid by Hudson during such period, minus the aggregate amount of dividends and distribution made by Hudson during such period, minus the aggregate amount of payments made with cash by Hudson to satisfy soil sampling and reclamation related to environmental cleanup at the Company’s former Hillburn, NY facility during such period (to the extent not already included in the calculation of EBITDA as determined by the Agent) to (b) the aggregate amount of all principal payments due and/or made, except principal payments related to outstanding revolving advances with regard to all funded debt (as defined in the PNC Facility) of Hudson during such period, plus the aggregate interest expense of Hudson during such period. EBITDA as defined in the PNC Facility shall mean for any period the sum of (i) earnings before interest and taxes for such period plus (ii) depreciation expenses for such period, plus (iii) amortization expenses for such period, plus (iv) non-cash charges.

	On October 25, 2013, we entered into the Second Amendment to the PNC Facility (the “Second PNC Amendment”) which, among other things, waived our requirement to comply with the minimum fixed charge coverage ratio covenant of 1.10 to 1.00 for the fiscal quarter ended September 30, 2013, under the PNC Facility. The covenant waiver was required primarily because of the adverse impact on our results of operations from the significant reduction in the selling price of HCFC-22 following the EPA’s final ruling allowing for the production or importation of 63 million and 51 million pounds of HCFC-22 in 2013 and 2014, respectively.

	The Second PNC Amendment also redefined the “Revolving Interest Rate” as well as the “Term Loan Rate” (as defined in the Facility) as follows:

	“Revolving Interest Rate” shall mean an interest rate per annum equal to (a) the sum of the Alternate Base Rate plus one percent (1.00%) with respect to Domestic Rate Loans and (b) the sum of the Eurodollar Rate plus two and three quarters of one percent (2.75%) with respect to the Eurodollar Rate.

	“Term Loan Rate” shall mean an interest rate per annum equal to (a) the sum of the Alternate Base Rate plus one percent (1.00%) with respect to the Domestic Rate Loans and (b) the sum of the Eurodollar Rate plus two and three quarters of one percent (2.75%) with respect to Eurodollar Rate Loans.

	The Second PNC Amendment suspended the minimum fixed charge ratio covenant until the quarterly period ending March 31, 2015 and set the minimum EBITDA for the quarters ended December 31, 2013 through December 31, 2014.

	On July 2, 2014, we entered into the Third Amendment to the PNC Facility (the “Third PNC Amendment”) which, among other things, extended the term of PNC Facility. Pursuant to the Third PNC Amendment, which was effective June 30, 2014, the Termination Date of the Facility (as defined in the Facility) has been extended to June 30, 2018. The Third PNC Amendment also amended the Minimum EBITDA covenant in the Facility to require that the Company maintain, on a trailing 12 month basis, tested quarterly, minimum EBITDA for the quarters ending June 30, 2014 through December 31, 2014, as follows:

	Period	Amount
	Six month period ending June 30, 2014	$	1,123,000
	Nine month period ending September 30, 2014	$	1,330,000
	Twelve month period ending December 31, 2014	$	802,000

	EBITDA for the six month period ended June 30, 2014 was $1,535,000, which was in compliance with the EBITDA covenant, as amended by the Third PNC Amendment, for the period. The EBITDA was calculated as follows:

		For the six months
		ended June 30, 2014
	Net income	$	468,000
	add: income tax provision		261,000
	Income before income taxes		729,000
	add: interest expense		395,000
	add: depreciation and amortization		411,000

	Earnings before interest, taxes, depreciation, and amortization	$	1,535,000

	EBITDA, which represents a non-GAAP measurement of certain financial results, does not represent and should not be considered as an alternative to net income or cash provided by operating activities as determined by GAAP. We make no representation or assertion that EBITDA is indicative of our cash provided by operating activities or results of operations. We have provided a reconciliation of the net loss to EBITDA solely for the purpose of complying with SEC disclosure requirements and not as an indication that EBITDA is a substitute measure for income from operations.

	The Company was in compliance with all covenants, as amended by the Third PNC Amendment, under the PNC Facility as of June 30, 2014. The Company’s ability to comply with these covenants in future quarters may be affected by events beyond the Company’s control, including general economic conditions, weather conditions, regulations and refrigerant pricing. Although we expect to remain in compliance with all covenants in the PNC Facility, as amended by the Third PNC Amendment, depending on our future operating performance and general economic conditions, we cannot make any assurance that we will continue to be in compliance.

	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 June 30, 2018, unless the commitments are terminated and the outstanding principal amount of the loans are accelerated sooner following an event of default.

	Note 4 – Capital Stock

	On June 6, 2014 the Company entered into an Underwriting Agreement with an investment banking firm for itself and as representative for two other investment banking firms (collectively, the “Underwriters”), in connection with an underwritten offering (the “Offering”) of 6,000,000 shares of the Company’s common stock, par value $0.01 per share (the “Firm Shares”). Pursuant to the Underwriting Agreement, the Company agreed to sell to the Underwriters, and the Underwriters agreed to purchase from the Company, an aggregate of 6,000,000 shares of common stock at a price of $2.3375 per share, and the price to the public was $2.50 per share. Pursuant to the Underwriting Agreement, the Company also granted the Underwriters a 30 day option to purchase up to 900,000 additional shares of its common stock to cover over-allotments, if any. The Company also agreed to reimburse certain expenses incurred by the Underwriters in the Offering.

	The closing of the Offering was held on June 11, 2014, at which time, the Company sold 6,900,000 shares of its common stock to the Underwriters (including 900,000 shares to cover over-allotments) at a price of $2.3375 per share, and received gross proceeds of $16,128,750. The Underwriters will also receive reimbursement of expenses of $150,000. The Company also incurred approximately $400,000 of additional expenses in connection with the Offering.
