NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ( Continued)

Cash, Cash Equivalents and Restricted Cash   --  The Company considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents. The Company had no balances held in a financial institution in the United States in excess of federally insured amounts at March 31, 2017 and December 31, 2016.

    Accounts Receivable   --  Accounts receivables consist of trade receivables arising in the normal course of business. The Company establishes an allowance for doubtful accounts, which reflects the Company’s best estimate of probable losses inherent in the accounts receivable balance. The Company determines the allowance based on known troubled accounts, historical experience, and other currently available evidence. 

The roll forward of the allowance for doubtful accounts for the three months ended March 31, 2017 and the year ended December 31, 2016 is as follows:

Inventory   --  Inventory is carried at the lower of cost or market, as determined on the first-in, first-out method.

Property and Equipment   --  Property and equipment are stated at cost. Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized, upon being placed in service. Expenditures for maintenance and repairs are charged to expense as incurred. Depreciation is computed for financial statement purposes on a straight-line basis over the estimated useful lives of the assets which range from three to ten years (See Note 4).

Long-Term Investments   --  Investments in non-consolidated companies are included in long-term investments in the consolidated balance sheet and are accounted for under the cost method and equity method. For these non-quoted investments, we regularly review the assumptions underlying the operating performance and cash flow forecasts based on information requested from these privately held companies. Generally, this information may be more limited, may not be as timely as and may be less accurate than information available from publicly traded companies. Assessing each investment's carrying value requires significant judgment by management. If it is determined that there is another-than-temporary decline in the fair value of a non-public equity security, we write-down the investment to its fair value and record the related write-down as an investment loss in the consolidated statement of operations.

Intangible Assets   --  Definite life intangible assets include patents. The Company accounts for definite life intangible assets in accordance with Financial Accounting Standards Board, (“FASB”) Accounting Standards Codification, (“ASC”) Topic 350, “Goodwill and Other Intangible Assets” and amortized the patents on a straight line basis over the estimated useful life of two to ten years. 

Goodwill -- Goodwill is evaluated for impairment annually, and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Triggering events that may indicate impairment include, but are not limited to, a significant adverse change in customer demand or business climate that could affect the value of goodwill or a significant decrease in expected cash flows.

Revenue Recognition and Sales Incentives   --  The Company accounts for revenue recognition in accordance with the Securities and Exchange Commission Staff Accounting Bulletin No. 101, “Revenue Recognition in Financial Statements” (SAB 101), FASB ASC 605 Revenue Recognition. The Company recognizes revenue when rights and risk of ownership have passed to the customer, when there is persuasive evidence of an arrangement, product has been shipped or delivered to the customer, the price and terms are finalized, and collections of resulting receivable is reasonably assured. Products are primarily shipped FOB shipping point at which time title passes to the customer. In some instances, the Company uses common carriers for the delivery of products. In these arrangements, sales are recognized upon delivery to the customer. The Company's revenue arrangements with its customers often include early payment discounts and such sales incentives are recorded against sales.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ( Continued)

The Company has received long-term contracts for the installation of various water filtrations systems and grants from government entities for development and use of silicon carbide membranes in various water filtration and treatment applications. Revenues from long-term contracts and grants are recognized on the percentage-of-completion method, measured by the percentage of project costs incurred to date to estimated total project costs for each long-term contract or grant multiplied by the long-term contract or grant income on a project-by-project basis. This method is used because management considers costs incurred to be the best available measure of progress on contracts in process.

Project costs of the long-term contracts and grants include  all direct material and labor costs and those indirect costs related to the project. Project costs are capitalized and accreted into cost of sales based on the percentage of the project completed. Should a loss be estimated on an incomplete project it would be recorded in the period in which such a loss is determined. Changes in estimated profitability of a project are recognized in the period in which the revisions are determined. The aggregate of costs incurred and income recognized on incomplete projects are recorded as costs in excess of billings and are shown as a current asset. 

The aggregate of billings in excess of related costs incurred and income recognized on projects is shown as a current liability.   

In Denmark, Value Added Tax (“VAT”) of 25% of the invoice amount is collected in respect of the sales of goods on behalf of tax authorities. The VAT collected is not revenue of the Company; instead, the amount is recorded as a liability on the balance sheet until such VAT is paid to the authorities.  

Advertising Cost   --  Cost incurred in connection with advertising of the Company’s products is expensed as incurred. Such costs amounted to $2,803 and $5,966 for the three months ended March 31, 2017 and 2016, respectively.

Research and Development Cost   --  The Company expenses research and development costs for the development of new products and systems as incurred. Included in operating expense for the three months ended March 31, 2017 and 2016 were $139,336 and $188,513, respectively, of research and development costs.

Income Taxes   --  The Company accounts for income taxes in accordance with FASB ASC Topic 740 Accounting for Income Taxes. This statement requires an asset and liability approach for accounting for income taxes.

Income (Loss) Per Share   --  The Company calculates earnings (loss) per share in accordance with FASB ASC 260 Earnings Per Share. Basic earnings per common share (EPS) are based on the weighted average number of common shares outstanding during each period. Diluted earnings per common share are based on shares outstanding (computed as under basic EPS) and potentially dilutive common shares. Potential common shares included in the diluted earnings per share calculation include in-the-money stock options and warrants that have been granted but have not been exercised.

Stock Options and Awards   --  The Company has granted stock options and awards to certain key employees and directors. See Note 13. The Company accounts for options in accordance with the provisions of FASB ASC Topic 718, Compensation – Stock Compensation. Non-cash compensation costs of $96,178 and $110,526 have been recognized for the vesting of options granted to employees with an associated recognized tax benefit of $ 22,525 and $43,699 for the three months ended March 31, 2017 and 2016, respectively.

Fair Value of Financial Instruments   -- The Company accounts for fair value measurements for financial assets and financial liabilities in accordance with FASB ASC Topic 820. The authoritative guidance, which, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as the exit price, representing the amount that would either be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

  NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ( Continued)

Unless otherwise disclosed, the fair value of the Company ’s financial instruments including cash, accounts receivable, prepaid expenses, investments, accounts payable, accrued expenses, capital lease obligations and notes payable approximates their recorded values due to their short-term maturities.

Accounting Estimates   --  The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets allowance for doubtful accounts receivable, cost in excess of billings, reserve for obsolete inventory, depreciation and impairment of property plant and equipment and impairment of goodwill and liabilities billings in excess of cost commitment and contingencies, the disclosures of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimated.

Recent Accounting Pronouncements   --  In May 2014, the Financial Accounting Standards Board (FASB) issued a new standard to achieve a consistent application of revenue recognition within the U.S., resulting in a single revenue model to be applied by reporting companies under U.S. generally accepted accounting principles. Under the new model, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the new standard requires that reporting companies disclose the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. On July 9 2015, the FASB agreed to delay the effective date by one year; accordingly, the new standard is effective for us beginning in the first quarter of 2018 and we expect to adopt it at that time. The new standard is required to be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying it recognized at the date of initial application. We have not yet selected a transition method, nor have we determined the impact of the new standard on our consolidated financial statements.

In 2015, the FASB issued an amended standard requiring that we classify all deferred tax assets and liabilities as non-current on the balance sheet instead of separating deferred taxes into current and non-current. The amended standard was adopted by the Company effective January 1, 2017 and had no effect on the underlying financial statements.

In February 2016, the FASB issued changes to the accounting for leases that primarily affect presentation and disclosure requirements. The new standard will require the recognition of a right to use asset and underlying lease liability for operating leases with an initial life in excess of one year. This standard is effective for us beginning in the first quarter of 2019. We have not yet determined the impact of the new standard on our consolidated financial statements.

In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties About an Entity ’s Ability to Continue as a Going Concern, that will require management to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. In connection with each annual and interim period, management will assess if there is substantial doubt about an entity’s ability to continue as a going concern within one year after the issuance date. Substantial doubt exists if it is probable that the entity will be unable to meet its obligations within one year after the issuance date. The new standard defines substantial doubt and provides example indicators. Disclosures will be required if conditions give rise to substantial doubt. However, management will need to assess if its plans will alleviate substantial doubt to determine the specific disclosures. The Company adopted the new standard and management evaluated the Company’s ability to continue as a going concern and made the required disclosures (See Note 2).

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting, which changes how companies account for certain aspects of share-based payments to employees. The new guidance requires all income tax effects of awards to be recognized in the income statement when the awards vest or are settled, allows an employer to repurchase more of an employee ’s shares than previously allowed for tax withholding purposes without triggering liability accounting, allows a company to make a policy election to account for forfeitures as they occur, and eliminates the requirement that excess tax benefits be realized before companies can recognize them. The new guidance also requires excess tax benefits and tax shortfalls to be presented on the cash flow statement as an operating activity rather than as a financing activity, and clarifies that cash paid to a tax authority when shares are withheld to satisfy its statutory income tax withholding obligation are to be presented as a financing activity. The standard was adopted effective January 1, 2017 and did not have a material effect on the Company’s financial position, results of operations and cash flows.

Other recent accounting pronouncements issued by the FASB did not or are not believed by management to have a material impact on the Company ’s present or future financial statements. 

NOTE 2 - GOING CONCERN

The accompanying consolidated financial statements have been prepared in conformity with generally accepted accounting principles of the United States of America, which contemplate continuation of the Company as a going concern. However, the Company has limited cash and incurred significant recent losses. These factors raise substantial doubt about the ability of the Company to continue as a going concern. There is no assurance that the Company will be successful in raising additional cash through the issuance of debt or equity instruments or return to achieving profitable operations. The financial statements do not include any adjustments that might result from the outcome of these uncertainties.  

Depreciation expense amounted to $ 258,654 and $351,743 for the three months ended March 31, 2017 and 2016, respectively. The property and equipment is held as collateral on lines of credit and guarantees with financial institutions. See Note 9.  

At March 31, 2017, our total investments of $5,354 consisted of an investment of $5,354 in LEA Technology in France to strengthen our sales channels in the French market. 

At December 31, 2016, our total investments of $5,282 consisted of an investment of $5,282 in LEA Technology in France to strengthen our sales channels in the French market.

NOTE 6   - DEFINITE-LIFE INTANGIBLE ASSETS

At March 31, 2017 and December 31, 2016, definite-life intangible assets, net of accumulated amortization, consisted of patents on the Company’s products of $4,775 and $5,614, respectively. The patents are recorded at cost and amortized over two to ten years. Amortization expense for the three months ended March 31, 2017 and 2016 was $839 and $745, respectively. Expected future amortization expense for the years ended are as follows: 

NOTE 7 - GOODWILL

The Company recorded Goodwill in connection with the acquisition of LiqTech Systems . Goodwill is evaluated for impairment annually in the fourth quarter of the Company’s fiscal year, and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Triggering events that may indicate impairment include, but are not limited to, a significant adverse change in customer demand or business climate that could affect the value of goodwill or a significant decrease in expected cash flows. Key variables included in evaluating goodwill for impairment include the pipeline of proposed potential customer sales, budgeted reoccurring sales, risk free interest rate and risk premium rate and future budgeted operating results. The Company recorded an impairment charge of $7,343,208 during the year ended December 31, 2016, as management's estimated fair value of the reporting unit did not exceed the carrying value during 2016 fourth quarter testing. 

NOTE 8   - NOTES PAYABLE

The Company had a 4.02% note payable used to purchase a vehicle with $ 51,065 and $54,929 balance outstanding as of March 31, 2017 and December 31, 2016. The note calls for monthly payments of $1,338, matures August 1, 2020 and is secured by the vehicle purchased.

The following represents the future maturities of long-term debt as of March 31, 2017:

NOTE 9   - LINES OF CREDIT

In connection with certain orders, we have to give the customer a working guarantee or a prepay ment guarantee or security bond. For that purpose, we previously had a guarantee credit line of DKK 94,620 (approximately $13,600 at March 31, 2017) with a bank, subject to certain base limitations. As of March 31, 2017, we had DKK 94,620 (approximately $13,600) in working guarantee against the line. This line of credit is guaranteed by Vækstfonden (the Danish state's investments fund) and is secured by certain assets of LiqTech Systems such as receivables, inventory and equipment.

NOTE 1 0   - LEASES

Operating Leases   -- The Company leases office and production facilities under operating lease agreements expiring in March 2021, August 2018, May 2018, and June 2017. In some of these lease agreements, the Company has the right to extend.

The future minimum lease payments for non-cancelable operating leases having remaining terms in excess of one year as of March 31, 2017 are as follows:

Lease expense charged to operations was $ 152,100 and $185,115 for the three months ended March 31, 2017 and 2016, respectively.

Capital Leases  --  The Company leases equipment on various variable rate capital leases currently calling for monthly payments of approximately $9,447, $599 and $539 expiring through July 2018.

For the three months ended March 31, 2017 and 2016, matching contributions were expensed and totaled $2,706 and $2,826, respectively.

Contingencies -- From time to time, we may be involved in litigation relating to claims arising out of our operations in the normal course of business.

On September 9, 2014, Mr. Raffaele Bruno Tronchetti Provera (“Plaintiff”), the 60% owner of LiqTech Italy s.r.l. (the “Venture”), sued LiqTech International A/S, the 40% owner of the Venture (“Defendant”), 750,000 Euros before the Court of Como, Italy alleging, among other things, that certain products provided by Defendant to the Venture were defective.   As of May 15, 2017, the case is in the preliminary stages where the court has appointed an expert in order to verify the quality of the products in order to determine whether there is sufficient evidence to proceed.  An evaluation of the outcome will only be possible after the results of the court appointment expert are known. This outcome of the court appointment expert is expected to be reported in the second quarter of 2017. Defendant believes that the claims are without merit and intends to vigorously defend any litigation.

In connection with certain orders, we have to give the customer a working guarantee or a prepayment guarantee or security bond. For that purpose, we have a guarantee line of DKK 94,620 (approximately $13,600 at March 31, 2017) with a bank, subject to certain base limitations. As of March 31, 2017, we had DKK 94,620 (approximately $13,600 at March 31, 2017) in working guarantee against the line. 

NOTE 1 2   - INCOME TAXES

The Company accounts for income taxes in accordance with FASB ASC Topic 740, Accounting for Income Taxes;, which requires the Company to provide a net deferred tax asset or liability equal to the expected future tax benefit or expense of temporary reporting differences between book and tax accounting and any available operating loss or tax credit carry forwards. The amount of and ultimate realization of the benefits from the deferred tax assets for income tax purposes is dependent, in part, upon the tax laws in effect, the Company’s future earnings, and other future events, the effects of which cannot be determined. In accordance with prevailing accounting guidance, the Company is required to recognize and disclose any income tax uncertainties. The guidance provides a two-step approach to recognizing and measuring tax benefits and liabilities when realization of the tax position is uncertain. The first step is to determine whether the tax position meets the more-likely-than-not condition for recognition and the second step is to determine the amount to be recognized based on the cumulative probability that exceeds 50%, Actual results could differ from these estimates.

As of March 31, 2017, the Company had net operating loss carryovers of approximately $11,743,000 for U.S. Federal purposes expiring through 2036; approximately $6,649,000 for Danish tax purposes, which do not expire; approximately $437,000 for German tax purposes, which do not expire and approximately $571,000 for Singapore tax purposes which do not expire.

As of March 31, 2017 and December 31, 2016, the Company established a valuation allowance of $3,675,000 and $3,542,000 for the tax components of LiqTech International Inc. and Liqtech NA, $1,157,000 and $1,095,000 for the tax components of LiqTech International AS and LiqTech Systems, $122,000 and $122,000 for the tax component of LiqTech Germany and $97,000 and $97,000 for the tax component of LiqTech Singapore as management could not determine that it was more than likely not that sufficient income could be generated by these components to realize the resulting net operating loss carry forwards and other deferred tax assets of these components. The change in the valuation allowance for the period ended March 31, 2017 was $133,400, $62,000, $0 and $0 for the US, Danish, German and Singapore components.

The Company is not relying on the reversal of deferred tax liabilities to realize the deferred tax assets. The same variable used by the Company in evaluating goodwill for impairment was used in assessing the realization of deferred tax assets (See Note 7).

The Company further considered the following positive and negative evidence:  

Positive Evidence

1 ) The Company executed in a Diesel Particular Filtration supplier contract with a Chinese entity.

2 ) For Danish tax purposes the Company is able to obtain tax refunds for research and development expenditures.

Negative Evidence  

1) The Company has noted a longer than anticipated sales cycle from proposals to signing filtration systems order.

2) The Company has a net loss from operations for the years ended December 31, 2016 and 2015.

3) The Company has experienced a decrease in liquid filter sales.

4) The Company has experienced delays in requested shipment date of large DPF sales orders and collection of receivables from large water treatment systems.

The temporary differences, tax credits and carry forwards gave rise to the following deferred tax asset (liabilities) at March 31, 2017 and December 31, 2016:  

A reconciliation of income tax expense at the federal statutory rate to income tax expense at the Company ’s effective rate is as follows for the three months ended March 31, 2017 and 2016: 

The components of income tax expense (benefit) from continuing operations for the three months ended March 31, 2017 and 2016 consisted of the following:

Deferred income tax expense / (benefit) results primarily from the reversal of temporary timing differences between tax and financial statement income.  

The Company files Danish, U.S. federal and  Minnesota state income tax returns. LiqTech International AS is generally no longer subject to tax examinations for years prior to 2011 for their Danish tax returns. LiqTech NA is generally no longer subject to tax examinations for years prior to 2013 for U.S. federal and U.S. states tax returns. 

For the three months ended March 31, 2017, Parent had 630,000 options outstanding to purchase shares of common stock of Parent at $0.74 to $1.01 per share and Parent had 700,000  warrants outstanding to purchase shares of common stock of Parent at $0.81 to $1.65 per share, which were not included in the loss per share computation because their effect would be anti-dilutive.

For the three months ended March 31, 2016, Parent had 1,071,000 o ptions outstanding to purchase shares of common stock of Parent at $0.74 to $1.90 per share and Parent had 7,325,575 warrants outstanding to purchase shares of common stock of Parent at $0.81 to $4.06 per share, which were not included in the loss per share computation because their effect would be anti-dilutive.

The exercise price of the warrants and the number of shares underlying the warrants are subject to adjustment for stock dividends, subdivisions of the outstanding shares of common stock and combinations of the outstanding shares of common stock. For so long as the warrants remain outstanding, we are required to keep reserved from our authorized and unissued shares of common stock a sufficient number of shares to provide for the issuance of the shares of common stock underlying the warrants.

Stock Options   

In August 2011, Parent ’s Board of Directors adopted a Stock Option Plan (the “Plan”). Under the terms and conditions of the Plan, the Board of Directors is empowered to grant stock options to employees, officers, and directors of the Company. At March 31, 2017, 630,000 options were granted and outstanding under the Plan. 

The Company recognizes compensation costs for stock option awards to employees based on their grant-date fair value. The value of each stock option is estimated on the date of grant using the Black-Scholes option-pricing model. The weighted-average assumptions used to estimate the fair values of the stock options granted using the Black-Scholes option-pricing model are as follows:

The Company recognized stock based compensation expense  related to the options of $25,519 and $110,526 for the three months ended March 31, 2017 and 2016, respectively. At March 31, 2017, the Company had approximately $80,408 of unrecognized compensation cost related to non-vested options expected to be recognized through December 31, 2025. 

A summary of the status of the options outstanding under the Plan at March 31, 2017 is presented below: 

A summary of the status of the options at March 31, 2017, and changes during the period are presented below:

At March 31, 2017, the Company had 333,333 non-vested options to purchase shares of Parent common stock  with a weighted average exercise price of $0.74 and with a weighted average grant date fair value of $0.46, resulting in unrecognized compensation expense of $80,408, which is expected to be expensed over a weighted-average period of 1.0 years.

The total intrinsic value of options at March 31, 2017 was $0. Intrinsic value is measured using the fair market value at the date of exercise (for shares exercised) or at March 31, 2017 (for outstanding options), less the applicable exercise price.
