(UNAUDITED)

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

REVERSE ACQUISITION

On August 24, 2011, pursuant to an Agreement and Plan of Merger, dated as of August 23, 2011 (the “Merger Agreement”), by and among LiqTech International, Inc.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Functional Currency / Foreign currency translation -- The functional currency of LiqTech International, Inc., LiqTech USA, Inc. and LiqTech NA is the U.S. Dollar. The Functional Currency of LiqTech Int. DK and LiqTech AS is the Danish Krone (“DKK”), the functional currency of LiqTech Germany is the Euro, the functional currency of LiqTech Singapore is the Singapore Dollar and the functional currency of LiqTech Asia is the South Korean Won. The Company’s reporting currency is the U.S. Dollar for the purpose of these financial statements. The foreign subsidiaries balance sheet accounts are translated into U.S. dollars at the period-end exchange rates and all revenue and expenses are translated into U.S. dollars at the average exchange rates prevailing during the period ending March 31, 2013 and 2012, respectively. Translation gains and losses are deferred and accumulated as a component of other comprehensive income in stockholders’ equity. Transaction gains and losses that arose from exchange rate fluctuations from transactions denominated in a currency other than the functional currency are included in the statement of operations as incurred.

Cash and Cash Equivalents -- 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 financial institution in the United States in excess of federally insured amounts at March 31, 2013 and December 31, 2012.

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, 2013 and the year ended December 31, 2012 is as follows:

	2013			2012
Allowance for doubtful accounts at the beginning of the period	$	1,243,500		$	389,032
Bad debt expense		27,925			1,078,365
Amount of receivables written off		-			(248,895	)
Effect of currency translation		(16,500	)		24,998
Allowance for doubtful accounts at the end of the period	$	1,254,925		$	1,243,500

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

Inventory consists of the following at March 31, 2013 and December 31, 2012:

	2013			2012
Furnace parts and supplies	$	588,165		$	529,358
Raw materials		641,516			705,025
Work in process		1,587,076			1,502,144
Finished goods		1,504,977			1,447,855
Reserve for obsolescence		(72,102	)		(72,567	)
Net Inventory	$	4,249,632		$	4,111,815

The Company’s inventory is held as collateral on the Company’s lines of credit.

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 3).

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 an-other-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.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

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. 

Revenue Recognition and Sales Incentives -- The Company's 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.

The Company has received various grants from government entities for development and use of silicon carbide membranes in various water filtration and treatment applications. Revenues from 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 grant multiplied by the 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 grants include all direct material and labor costs and those indirect costs related to project. Project costs are capitalized and accreted into cost of sales based on the percentage of the project completed. The Company has never recorded a loss on these projects, 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 $11,788 and $20,447, for the three months ended March 31, 2013 and 2012, respectively.

Research and Development Cost -- The Company expenses research and development costs for the development of new products as incurred. Included in operating expense for the three months ended March 31, 2013 and 2012 were $146,985, and $226,674, 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.

Earnings / (Loss) Per Share -- The Company calculates earnings 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 that have been granted but have not been exercised.

11

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Stock Options -- The Company has granted stock options to certain key employees (See Note 11). During the years presented in the accompanying consolidated financial statements, the Company has granted options. The Company accounts for options in accordance with the provisions of FASB ASC Topic 718, Compensation – Stock Compensation. Non-cash compensation costs of $31,369 and $32,602 have been recognized for the vesting of options granted to employees with an associated recognized tax benefit of $0 for each of the periods ended March 31, 2013 and 2012.

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:

·   Level 1. Observable inputs such as quoted prices in active markets for identical assets or liabilities;

·   Level 2. Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

·   Level 3. Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

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 and liabilities, 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 July 2012, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2012-02, Intangibles-Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment (ASU 2012-02). ASU 2012-02 was issued with the intent of reducing the cost and complexity of performing impairment tests for indefinite-lived intangible assets by providing an entity with the option to first make a qualitative assessment about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it is necessary to perform a quantitative impairment test. The amendments in this update also enhance the consistency of impairment testing guidance among long-lived asset categories by permitting the qualitative assessment, which is similar to the previously updated guidance for goodwill impairment testing provided in ASU 2011-08. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted, including for annual and interim impairment tests performed as of a date before July 27, 2012, if a public entity's financial statements for the most recent annual or interim period have not yet been issued. The Company adopted ASU 2012-02 during the third quarter ended September 30, 2012. Adoption of this standard did not have a material impact on the Company's consolidated financial statements.

 NOTE 9 – 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.

The temporary differences, tax credits and carry forwards gave rise to the following deferred tax asset (liabilities) at March 31, 2013 and December 31, 2012:

	2013			2012
Vacation accrual	$	4,093		$	4,093
Allowance for doubtful Accounts		243,314			243,314
Reserve for obsolete inventory		19,925			19,925
Net current tax assets	$	267,332		$	267,332
Business tax credit carryover		25,379			25,379
Net operating loss carryover		1,139,923			856,517
Excess of book over tax depreciation		(802,797	)		(805,949	)
Net deferred tax liability	$	(362,505	)	$	(75,947	)

15

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 meet 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%.

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 can difficult to determine and can only be estimated. Management estimates that it is more likely than not that the Company will generate adequate net profits to use the deferred tax assets; management has estimated that all of the deferred tax will be realized and consequently, a valuation allowance was not recorded.

As of March 31, 2013, the Company had net operating loss carryovers of approximately $2,100,000 for U.S. Federal purposes expiring through 2033, approximately $317,000 for Danish Tax purposes which do not expire, $63,000 for German tax purposes which do not expire and $45,000 for Singapore tax purposes which do not expire.

A reconciliation of income tax expense at the federal statutory rate to income tax expense at the Company’s effective rate was as follows at March 31, 2013 and 2012:

	2013			2012
Computed tax at expected statutory rate	$	(328,670	)	$	147,417
State and local income taxes, net of federal benefits		-			6,945
Non-deductible expenses		-			849
Non-US income taxed at different rates		31,806			(34,477	)
Manufacture and other tax credits		-			(13,600	)
Other items		-			3,842
Income tax expense	$	(296,864	)	$	110,977

The components of income tax expense (benefit) from continuing operations for the years ended March 31, 2013 and 2012 consisted of the following:

	2013		2012
Current income tax expense:
Danish	$	-	$	120,107
Federal		-		60,600
State		-		2,779
Current tax expense	$	-	$	183,486

Deferred tax expense (benefit) arising from:
Excess of tax over financial accounting depreciation	$	-		$	43,766
Net operating loss carryover		(296,864	)		(87,021	)
Allowance for doubtful accounts		-			(10,504	)
Reserve for obsolete inventory		-			(18,750	)
Deferred tax expense	$	(296,864	)	$	(72,509	)
Income Tax Expense (Benefit)	$	(296,864	)	$	110,977

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

16

The Company files Danish  and U.S. federal, and Minnesota state income tax returns, and LiqTech AS and LiqTech International AS are generally no longer subject to tax examinations for years prior to 2007 for their Danish tax returns.  LiqTech NA is generally no longer subject to tax examinations for years prior to 2008 for U.S. federal and U.S. states tax returns.

Overview

We are a clean technology company that provides state-of-the-art technologies for gas and liquid purification by manufacturing ceramic silicon carbide filters. For more than a decade, we have developed and manufactured products of re-crystallized silicon carbide. We specialize in three business areas: ceramic membranes for liquid filtration, diesel particulate filters for the control of soot exhaust particles from diesel engines and kiln furniture for the refractory industry. Using nanotechnology, we develop proprietary products using patented silicon carbide technology. Our products are based on unique silicon carbide membranes which facilitate new applications and improve existing technologies. We market our products from our offices in the United States and Denmark, and through local representatives in Italy, Germany, France, Korea, Brazil and Singapore. The products are shipped directly to customers from our production facilities in the United States and Denmark.

The terms “LiqTech”, “we”, “our”, “us”, the “Company” or any derivative thereof, as used herein refer to LiqTech International, Inc., a Nevada corporation, together with its direct and indirect wholly-owned subsidiaries, including LiqTech USA, Inc., a Delaware corporation (“LiqTech USA”), which owns all of the outstanding equity interest in LiqTech International A/S, a Danish limited company, organized under the Danish Act on Limited Companies of the Kingdom of Denmark (“LiqTech Denmark International”) and LiqTech NA, Inc., a Delaware corporation (“LiqTech Delaware”). Collectively, LiqTech USA, LiqTech Denmark International and LiqTech Delaware are referred to herein as our “Subsidiaries”. On August 23, 2012, LiqTech A/S, a Danish limited company (“LiqTech Denmark”) and former subsidiary of the Company was merged with and into LiqTech Denmark International.

We conduct operations in the Kingdom of Denmark and the United States. Our Danish operations are located in the Copenhagen, Denmark area and our U.S. operations are conducted by LiqTech Delaware located in White Bear Lake, Minnesota. In October and December 2011, we opened sales offices in France and Germany and in January2012, we opened a sales office in Singapore.

Our Products

We manufacture and sell (i) ceramic membranes for the filtration of liquid; (ii) diesel particulate filters for the control of soot exhaust particles from diesel engines and (iii) to a much lesser extent, kiln furniture to support ceramics during the firing process.

Ceramic Silicon Carbide Membranes for Liquid Filtration

Under the “LiqTech” and “Cometas” brand names, we manufacture and sell ceramic silicon carbide membranes for liquid filtration using our patented silicon carbide technology (“SiC Filters”) that currently focus on hydrocarbon production-derived contaminated water, which we refer to herein as “produced water” and pre-filtration for reverse osmosis. Our SiC Filters have been used in the following applications by our clients:

● Produced water: Our membranes can be used for the filtration of water from oil produced in offshore platforms. We have performed testing with many of the major international private and public oil and gas companies. We have recently been awarded a contract by one of the major international oil and gas companies to provide and service produced water filters on one of its offshore platforms. Our products have been delivered and the initial service period under the contract commenced.

● Pre-filtration of reverse osmosis drinking water: Prior to passing through reverse osmosis membranes to produce drinking or industrial water from sea or surface water, the sea or surface water must be pre-filtered. We have performed successful tests for the pre-filtration of sea and surface water for this purpose with numerous clients, including Arteron in Malaysia, a company producing compact drinking water, Hoimyung Corp in South Korea, a supplier of industrial waste water systems and pretreatment for reverse osmosis, Kemic Vater Cleaning in Denmark, a supplier of drinking water equipment, and Puretec in Israel, a producer of reverse osmosis systems.

20

● Treatment of ballast water: Our liquid filtration membranes can be applied to limit the spreading of non-native species that may be transported in the ballast water of sea-going vessels. We have partnered with Singapore based companies and R&D centers to develop a solution for the ballast water treatment market. A distributor in Japan is in contact with shipyards seeking filtration solutions for our ballast water systems.

● Industrial applications: Our membranes have performed successful tests in industrial applications for the removal of a variety of substances such as heavy metal (Haldor Topsoe, Denmark), legionella (HYTEK Italy), manure (Bioffuel Technology, Denmark), pool and spa water (Provital, Denmark) and raw sugar (Al Khaleej Sugar, UAE).

● Producing clean drinking water: The potential for the use of LiqTech SIC membranes in drinking water production is diverse and the benefits are numerous. Some examples include: group water – removal of precipitated salts such as iron and manganese; surface water – removal of organic suspended solids and humic acid; and sea water – pre-filtration before reverse osmosis.

● Waste water treatment: Our membranes can be used to remove suspended solids in waste water treatment. Our membranes have performed successful tests for treating waste water with Hydrosolutions, Puretec in Israel and Asia Pacific Water Technologies in South Korea.

Our products are based on the following silicon carbide membrane technologies:

● CoMem is a unique patented membrane technology that utilizes a cross-flow structure to handle high concentrations of suspended solids found in produced water from the oil and chemical industry, wastewater from industrial processes and manure filtration; and

● Aqua Solution integrates a dead-end structural design with cutting-edge membrane technology in a solution specifically designed for applications in pre-treatment for reverse osmosis, wastewater treatment and pool and spa filtration.

Our filters are manufactured with a silicon carbide ceramic membrane based on a patented technology, and we are not aware of any other company that makes both the substrate (honeycomb) and the membrane (the part which accomplishes the filtering) solely from silicon carbide.

The advantages of our SiC membrane compared to other pre-filtration systems for reverse osmosis are:

● Our SiC membrane offers the same water flow as commonly used sand filters which take up to 400 times more space and have pore sizes at least three times bigger than our SiC membrane, and reduces the number of membrane elements and pressure vessels;

● With our SiC membrane, high flow capacities are achieved at very low pressures, which reduces energy costs;

● Our SiC membrane reduces water consumption for sand filter backwash; and

● Our SiC membrane eliminates consumption/maintenance of cartridges.

On February 14, 2013, we announced that our ultra-filtration Silicon Carbide (SiC) membrane product has been approved for liquid sterilization according to the recognized American Society for Testing and Materials (ASTM) standard F838-05 for liquid filtration. This standard is widely used for pharmaceutical, food & beverage and drinking water applications. The combination of the unmatched performance of SiC membranes compared to any other ceramic membrane material in terms of liquid flux, chemical resistance and product life, now combined with the capability of providing sterile filtration, represents disruptive technology to the existing norm, and is an industry game-changer for Drinking Water, Biotech and Food & Beverage applications. Our SiC membranes enable mechanical removal of bacteria, which is cheaper and more reliable than any other sterilization technology. We believe we are the only membrane manufacturer worldwide to achieve liquid sterilization with a SiC membrane.

21

The independent Danish Technological Institute (DTI) laboratory conducted a sterile membrane certification according to the ASTM standard. Following the test procedure set forth by ASTM, our SiC membranes were evaluated in terms of bacteria rejection. DTI conducted in that certification that the membrane filter has the ability to retain bacteria corresponding to a log 7 reduction.  The ability to retain bacteria corresponding to a log 7 reduction (99.99999% removal) is recognized as sterile filtration, i.e. the membrane can be considered as a bacterial barrier.  On the basis of this achieved ASTM standard, we are now considering expanding our strategic focus beyond the existing business areas of industrial wastewater treatment and produced water treatment and toward new areas such as Biotech, food & beverage, and drinking water, where our SiC membranes may offer sterile filtration with a significant value proposition for the end-users.

On February 19, 2013, we announced that our SiC membranes are currently being used in the recovery of protein in a foodstuff application in China. FANRUNSI (Shanghai) Fluid Technology Co. Ltd., a Chinese engineering firm located in Shanghai, has installed 240 square meters of our SiC membranes at a Chinese customer location. The end-user is considering a further expansion of additional SiC membranes worth more than $1 million in 2013.

On February 21, 2013, we announced the newest product to our portfolio, SiC membrane discs. The membrane disc system is based on a principle of creating cross-flow by rotating the membrane as an alternative to pumping the liquid across the membrane in the traditional tubular setup. Energy consumption is only 17% compared to regular cross-flow. The membrane disc system can handle liquids with high solid content and will therefore be used in applications such as wastewater treatment, manure concentration and pharmaceuticals. The application is also suitable in algae dewatering before final extraction of Omega 3 and other high-value content for production of feed or bio ethanol. These applications are growing markets, and all face a continuous challenge in finding energy-effective treatment solutions. We believe that our SiC membrane discs will set the standard for requirements in future system design, due to higher flux and better chemical resistance at a comparable price to other solutions. We believe the market for membrane discs has strong potential alongside our other tubular and flat sheet membranes.

The product was developed with funding from the Danish foundation for Green Development and Demonstration Program (GUDP – Groen udvikling og demonstrations program). The foundation has partially funded the development of the SiC membrane discs for concentration of manure however we retain full ownership of the intellectual property. Concentration of manure will enhance the production of biogas compared to gasification of raw manure, and will limit the CO2 emission from transportation of the untreated manure prior to the gasification.

We intend to target the membrane disc product through a strategic partnership with an experienced system integrator. The system integrator has a long history in designing membrane disc equipment. The total market size for sludge treatment is estimated to reach $5.8 billion in 2013, growing at a compound annual growth rate of 4.6% (Source: Filtration Industry AnalystVolume 2008, Issue 12, December 2008, Pages 5). We believe the membrane technology portion of this market is approximately 5% of the total market, or approximately $290 million.

In addition to the above, the International Feed Industry Federation states that the feed production market reached 873 million metric tons in 2012, representing a market worth $350 billion. It is further estimated that membranes could account for $350-$700 million of the total market according to Transparency Market Research.

On March 5, 2013, we announced that we have launched a new state-of-the-art SiC Flat Sheet Membrane (FSM) disc for Membrane Bioreactors (MBR) and Moving Bed Bioreactors (MBBR) for wastewater treatment.

The FSM uses the outside-in filtration principle. This allows either a pressurized mode or a vacuum suction mode of operation which reduces the cost of installation. The FSM module is submerged in a tank containing dirty water and by applying moderate suction pressure, clean water is produced. This configuration is mainly used in modern MBR and MBBR wastewater treatment systems and reduces the strain on housings, pumps and controls. With this new expansion of the product portfolio, we believe we will be able to cover a wider spectrum of the market. While our tubular filter is suited for low-solid content feeds, the FSM is better suited for higher-solid content applications and our rotating discs target very high solid content feeds.

The high clean-water permeability of the SiC material, being around 20 times more permeable than conventional polymeric 0.1um UF membranes and 4 times more permeable than aluminum oxide 0.1um UF membranes (competing ceramic material), allows compact systems that save valuable footprint space for our customers.

22

The FSM targets the waste water market, which we believe is among the most important applications in membrane technology. The MBR market reached a size of about $800 million in 2011 and is expected to grow at approximately 20% per year to exceed $3 billion in 2018 according to Global water market research team at Frost & Sullivan. Published in Waterworld Magazine.

This new technology offers a flexible high-performance solution with the outstanding material advantages of SiC, providing customers ultra-compact systems with the reliability and robustness of a ceramic membrane.

We have entered into cooperation agreements with two system integrators with specific know-how and market access to develop market-driven products with what we believe to be the best value proposition. We currently expect to generate revenue from the sales of the FSMs during 2013.

For the years ended December 31, 2012 and 2011, we received grants from governmental entities of $549,648 and $3,039,118, respectively. In 2011, we received a $2 million grant from The Danish National Advanced Technology Foundation to develop a SiC-based membrane that can perform reverse osmosis. If successful, we believe this will be the first inorganic reverse osmosis membrane ever developed. The goal is to produce clean drinking water from sea water.

We believe increased government regulation on the treatment of produced water may increase our sales of SiC membranes. Existing technology may have difficulty meeting any increased requirements because the hydro-cyclone technology currently used in most treatments of produced water is not effective at removing suspended solids and is prone to clogging.

For the three months ended March 31, 2013 and March 31, 2012, our sales of liquid filters and services were $1,202,952 and $901,926, respectively, and accounted for 35% and 14% of our total sales, respectively.

Diesel Particulate Filters

We offer diesel particulate filters (“DPF”) for exhaust emission control solutions to the verified retrofit and the original equipment manufacturer (OEM) market through our direct sales force. DPF sales are generally made to distributors specializing in sales to end users. We use a proprietary “nano washcoat” to provide catalytic coating for anything from diesel particulate filters to catalytic converters. We have developed a robust silicon carbide diesel particulate filter that is especially useful for vehicles that produce a high soot load, and, if properly maintained, should last as long as the vehicle’s engine. Our DPFs are ideal for off-road vehicles because of their strength, chemical non-reactive nature, temperature resilience and thermal conductivity. Our DPF products are sold worldwide, under the LiqTech brand name.

Our silicon carbide filters can handle higher soot loads than filters that do not use a silicon carbide membrane, which makes them ideal for situations in which engines infrequently reach high enough temperatures to burn off soot. Examples include:

● Garbage trucks;

● Port vehicles;

● Diesel pickup trucks not carrying a full load;

● Off-road construction vehicles that idle for long periods of time; and

● Intra-city vehicles that do not reach highway speeds.

Most of our competitors’ DPFs do not use a silicon carbide membrane.

For the three months ended March 31, 2013 and 2012, our sales of diesel particulate filters were $1,932,305 and $5,337,566, respectively, and accounted for 57% and 84% of our total sales, respectively.

Kiln Furniture

Kiln furniture refers to all items used in a kiln to support ceramics that creates additional space to maximize the number of items for each firing. Our high-quality SiC kiln furniture is thinner (allowing more items to be added for each firing), withstands higher heat, lasts longer and reduces the firing time (reducing energy costs) as compared to cordierite, mullite and oxide bonded kiln furniture.

23

We intend to produce kiln furniture as a means to maximize the efficiency of our manufacturing process and not as one of our primary products.

We began selling kiln furniture in 2011 and our sales for the three months ended March 31, 2013 and March 31, 2012, were $263,891 and $102,229, respectively, and accounted for 8% and 2% of our total sales, respectively.

Our Manufacturing

We currently manufacture our products in facilities located in Ballerup, Denmark and White Bear Lake, Minnesota. The main raw materials that we use in our manufacturing processes are silicon carbide, platinum and palladium. We purchase these commodities from various sources generally based upon availability and price. There is a limited supply of silicon carbide available to us. As other industries develop products utilizing silicon carbide, we may not be able to obtain adequate supplies of silicon carbide required for the manufacture of our existing and planned future water filtration products. Any increased demand for silicon carbide, platinum or palladium could increase the price we must pay to obtain it and could adversely affect our profitability.  However, our management believes that we could obtain satisfactory substitutes for these materials should they become unavailable.

Prior to our entry into the new subcontract agreement with Scandinavian Brake Systems, as discussed below, our manufacturing facilities operated at peak capacity. We currently have a subcontract agreement for production capacity with a subcontractor located in Tennessee. We have also entered into a new subcontract agreement with Scandinavian Brake Systems to utilize the production capacity of their Notox division. The new subcontract arrangement, which extends until the end of 2014, is expected to significantly increase our production capacity.

We have plans to expand our production capacity in both Denmark and Minnesota, primarily through additional investment in equipment relating to our liquid filtration products, when this becomes necessary.

Sales, Marketing and Distribution

Our products are sold primarily to large industrial customers that use our products for gas and liquid filtration. To date, most of our sales have been in the transportation sector, and we are seeking to broaden our sales into other areas such as produced water in the oil and gas market, desalination market and other water purification markets. We had had no customers who accounted for more than 10% of total sales at March 31, 2013. For the three months ended March 31, 2012, our four largest customers accounted for approximately 19%, 17%, 11% and 8%, respectively, of our net sales (approximately 55% in total). We plan to actively market our existing products to new customers as we increase our production capacity. We currently have 10 full-time sales personnel or distribution agents. We promote our products through direct contact to potential customers and by meeting potential customers in trade fairs and exhibitions.

Government Regulation

We do not believe that we are subject to any special governmental regulations affecting our products in the countries in which we have operations, except that in Minnesota, we are required to comply with the Minnesota Air Pollution standards related to the use of our incinerator located in our Minnesota facilities. We are subject to numerous health and safety laws and regulations. In the United States, these laws and regulations include the Federal Occupation Safety and Health Act and comparable state legislation. We are also subject to similar requirements in other countries in which we have extensive operations, including Denmark, where we are subject to various regulations. These regulations are frequently changing, and it is impossible to predict the effect of such laws and regulations on us in the future. We actively seek to maintain a safe, healthy and environmentally friendly workplace for all of our employees and those who work with us.

Research and Development

We currently have five full-time employees spending a majority of their time on research and development. For the three months ended March 31, 2013 and 2012, we spent $146,985 and $226,674, respectively, on research and development.

24

Competition

Our products compete with other filters that are made using both ceramic and plastic membranes. Most of our competitors are large industrial companies. However, we believe our patented technology allows us to produce high quality, low cost products that give us an advantage over many of our competitors, many of which have greater financial, technological, manufacturing and personnel resources. We intend to continue to devote resources to improving our products in order to maintain our existing customers and to add new customers.

Recent Developments

On April 1, 2013 Mr. Helmer was appointed as our new Chief Executive Officer (See Item 5 herein below). Over the course of more than 40 years Mr. Helmer has in many different situations successfully demonstrated his talent for leading and growing companies into meaningfully larger and more profitable companies including his role as CEO of GIGA A/S, a Danish company in the NKT Group.  When he joined GIGA as its seventh employee, it had limited capital, was not profitable and had revenue of less than $1 million. In less than 5 years, GIGA employed 100 people, and was generating revenues and pre-tax profit of $135 million and $73 million, respectfully. In 2000 Intel (USA) acquired GIGA for $1.25 billion.

On March 25, 2013 we entered into an agreement with a global leader in oilfield equipment and services, FMC Technologies, Inc. (NYSE: FTI), for the use of our state-of-the-art disruptive silicon carbide membrane technology for oil/gas applications. This exclusive agreement will bring LiqTech International's silicon carbide membrane technology into the highly attractive unconventional shale oil/gas sector and will allow for the development of new water treatment systems. The agreement includes a multi-year, multi-million dollar commitment towards LiqTech technology in order for FMC Technologies to maintain exclusivity.

On March 5, 2013 we launched a new state-of-the-art Silicon Carbide (SiC) Flat Sheet Membrane (FSM) disc for Membrane Bioreactors (MBR) and Moving Bed Bioreactors (MBBR) for wastewater treatment.

On February 26, 2013 we appointed Mr. Mark Vernon, Group Chief Executive Officer of Spirax-Sarco Engineering plc (London Stock Exchange: SPX) to our Board of Directors. Mr. Vernon has enjoyed a long career in the industrial engineering industry, with broad experience in strategic planning, operations management, marketing, sales and new product development. He has travelled extensively, visiting over 65 countries worldwide, and has established businesses and manufacturing operations in many emerging markets. Since April 2008, Mr. Vernon has served as Group Chief Executive Officer of Spirax-Sarco a multi-national industrial engineering company headquartered in the UK, comprising more than 50 operating companies located in 35 countries around the world with revenues exceeding $1 billion. Mr. Vernon joined Spirax-Sarco in 2003 as President of the Group's USA operating company before being appointed to their Board of Directors in 2006 with responsibility for business operations in North and South America. Mr. Vernon also currently serves as a Director of Senior plc, a $1.2 billion UK-based aerospace and industrial engineering business.

On February 21, 2013 we announced the newest product to the Company's portfolio, SiC membrane discs. The membrane disc system is based on a principle of creating cross-flow by rotating the membrane as an alternative to pumping the liquid across the membrane in the traditional tubular setup. Energy consumption is only 17% compared to regular cross-flow membranes.

On February 19, 2013 we announced that LiqTech SiC membranes are currently being used in the recovery of protein in a foodstuff application in China. FANRUNSI (Shanghai) Fluid Technology Co. Ltd., a Chinese engineering firm located in Shanghai, has installed 240 m2 of LiqTech SiC membranes at a Chinese customer location.  

On February 14, 2013 we announced that the Company's ultra-filtration Silicon Carbide (SiC) membrane product has been approved for liquid sterilization according to the recognized ASTM standard F838-05 for liquid filtration. This standard is widely used for pharmaceutical, food & beverage and drinking water applications. The combination of the unmatched performance of SiC membranes compared to any other ceramic membrane material in terms of liquid flux, chemical resistance and lifetime, now combined with the capability of providing sterile filtration, represents disruptive technology to the existing norm, and is an industry game-changer for Drinking Water, Biotech and Food & Beverage applications. The LiqTech SiC membranes enable mechanical removal of bacteria, which is cheaper and more reliable than any other sterilization technology.

Comparison of the three month periods ended March 31, 2013 and March 31, 2012

Revenues

Net sales for the three month period ended March 31, 2013 were $3,399,148 compared to $6,341,721 for the same period in 2012, representing a decrease of $2,942,573, or 46.4%. The decrease in sales consisted of a decrease in sales of DPFs of $3,405,261 and an increase in sales of liquid filters and kiln furniture of $301,026 and $161,662 respectively. The decrease in demand for our DPFs is mainly due to a postponement in use of mandates in the US market and the absence ofthe low emission zone activity in London, which contributed to our net sales for the three month period ended March 31, 2012. The increase in demand for our liquid filters and kiln furniture is due to an increase in worldwide sales of our products.

Gross profit

Gross profit for the three month period ended March 31, 2013 was $562,023 compared to $2,089,684 for the same period in 2012, representing a decrease of $1,527,661 or 73.1%. The decrease in gross profit was due to a decrease in sales for the period ended March 31, 2013 compared to the same period in 2012.

26

Expenses

Total operating expenses for the three month period ended March 31, 2013 were $1,414,584, a decrease of $194,520, or 12.1%, compared to $1,609,104 for the same period in 2012. This decrease in operating expenses is attributable to a decrease in selling and marketing expenses of $85,993 or 13.0%, general and administrative expenses of $28,838 or 4.0% and research and development expenses of $79,689 or 35.2% compared to the same period in 2012.

Selling and marketing expenses for the three month period ended March 31, 2013 were $573,925 compared to $659,918 for the same period in 2012, representing a decrease of $85,993 or 13.0%. This decrease is attributable to decreased selling and marketing expenditures for the three month period ending March 31, 2013 compared to the same period in 2012. While we believe that investment in sales will produce attractive returns for the Company and our shareholders, profitability from such investments will likely take several fiscal quarters to be realized.

General and administrative expenses for the three month period ended March 31, 2013 were $693,674 compared to $722,512 for the same period in 2012, representing a decrease of $28,838 or 4%. This decrease is attributable to decreased general and administrative expenditures for the three month period ending March 31, 2013 compared to the same period in 2012, but the levels for the three months ended both March 31, 2013 and 2012 were approximately what we expect for comparable periods going forward. During the three months ended March 31, 2013, the Company also added an additional $27,925 to its bad debt reserve compared to $110,000 for the same period in 2012. Included in the three month period ending March 31, 2013 is an additional $31,369 of non-cash compensation expense for options granted to employees and management compared to $32,602 for the three month period ended March 31, 2012. 

Research and development expenses for the three month period ended March 31, 2013 were $146,985 compared to $226,674 for the same period in 2012, representing a decrease of $79,689 or 35.2%. This decrease is attributable to decreased research and development expenditures for the three month period ending March 31, 2013 compared to the same period in 2012.

Net Income/(Loss)Attributable to LiqTech

Net loss for the three month period ended March 31, 2013 was $669,811 compared to net income of $322,601 for the same period in 2012, representing a decrease of $992,412. This decrease was primarily attributable to a decrease of $1,527,661 in our gross profit partially offset by a decrease of $194,520 in operating expenses and a decrease in income tax expense of $407,841. The largest contributor to the decrease in operating expenses was a decrease in selling and marketing expenses of $85,993 or 13.0%, compared to the same period in 2012.

Liquidity and Capital Resources

We have historically satisfied our capital and liquidity requirements through internally generated cash from operations and our available lines of credit. At March 31, 2013, we had cash of $3,115,618 and working capital of $7,437,217 and at December 31, 2012 we had cash of $3,873,338 and working capital of $8,069,595. At March 31, 2013, our working capital decreased by $632,378. Total current assets were $10,992,438 and $11,826,816 at March 31, 2013 and December 31, 2012, respectively and total current liabilities were $3,555,221 and $3,757,221 at March 31, 2013 and December 31, 2012, respectively.

On March 2, 2012, we completed a registered public offering of our common stock. As part of the closing, we issued 2,511,500 shares of our common stock in a registered direct placement of our shares at a per share price of $3.25. The net proceeds to us from the closing were approximately $7.1 million. We intend to use the net proceeds from the offering for the development and marketing of our products, the engineering, development and testing of our membranes, and the opening of local sales offices in certain countries outside of the U.S. and Denmark. Pending application of such proceeds, we expect to invest the proceeds in short-term, interest-bearing, investment-grade marketable securities or money market obligations.

LiqTech Int. DK has a DKK 6,000,000 (approximately $1,027,908 at March 31, 2013) standby line of credit with a bank, subject to certain borrowing base limitations. Outstanding borrowings are due on demand. There was $0 outstanding as of March 31, 2013 and December 31, 2012. Interest is charged quarterly at 3.76% per annum at March 31, 2013 and the line is secured by certain of the Company’s receivables, inventory and equipment. At March 31, 2013, the line had been paid down to $0 outstanding, with $1,027,908 available on the line of credit.

LiqTech Int. DK has also a DKK 3,000,000 (approximately $513,954 at March 31, 2013) standby line of credit with a bank, subject to certain borrowing base limitations. Outstanding borrowings are due on demand. There was $0 outstanding as of March 31, 2013 and December 31, 2012. Interest is charged quarterly at 3.76% per annum at March 31, 2013 and the line is secured by certain of the Company’s receivables, inventory and equipment. At March 31, 2013, the line had been paid down to $0 outstanding, with $513,954 available on the line of credit.

27

In general, lines of credit in Denmark are due on demand. We do not believe that any of our lines of credit will be called but, if they were called, we believe that we could refinance with other lenders in Denmark with similar terms.

We believe that our cash flow together with currently available funds from our existing lines of credit and other potential sources of funds will be sufficient to fund our anticipated working capital needs and capital spending requirements for the foreseeable future. However, if we were to incur any unanticipated expenditures or the negative trend of our operating cash flow does continue, such circumstances could put a substantial burden on our cash resources.

We may also need additional funds for possible future strategic acquisitions of businesses, products or technologies complementary to our business. If additional funds are required, we may raise such funds from time to time through public or private sales of equity or debt securities. Financing may not be available on acceptable terms, or at all, and our failure to raise capital when needed could materially adversely impact our growth plans and our financial condition and results of operations. Additional equity financing may be dilutive to holders of our common stock, and debt financing, if available, may involve significant cash payment obligations and covenants that restrict our ability to operate our business.

Cash Flows

Cash provided (used) by operating activities is net income (losses) adjusted for certain non-cash items and changes in assets and liabilities. Cash used by operating activities for the period ended March 31, 2013 was $533,657, representing a decrease of $1,267,551, compared to cash provided by operating activities of $733,894 for the period ended March 31, 2012. The $533,657 in cash used by operating activities for the period ended March 31, 2013 was mainly due to the net loss of $669,811, the increases of $137,817 in inventory, the decrease of $247,459 in accounts receivable and a decrease of $204,904 in accrued expenses.

The increases in inventory, the decrease in accounts receivable and the decrease in accrued expenses were all due to normal variation in course of business.

Cash used in investing activities was $129,720 for the year period ended March 31, 2013, as compared to cash used in investing activities of $671,871 for the period ended March 31, 2012. Cash used in investing activities decreased in 2013, compared to 2012, primarily due to proceeds of $689,827 received in 2011 on insurance claims as a result of fire of the company’s building in 2011. We anticipate that we will continue to invest in additional production equipment in order to meet the demand for our products.

Cash used by financing activities was $76,688 for the year period ended March 31, 2013, as compared to cash provided by financing activities of $5,353,131 for the year period ended March 31, 2012. The change of $5,429,819 in cash provided by financing activities in 2012, compared to 2013, was primarily due to cash received in connection with the stock offering during the first quarter 2012, when the Company issued 2,511,500 new shares of common stock at 3.25 per share.

Significant Accounting Policies and Critical Accounting Estimates

The methods, estimates, and judgments that we use in applying our accounting policies have a significant impact on the results that we report in our consolidated financial statements. Some of our accounting policies require us to make difficult and subjective judgments, often as a result of the need to make estimates regarding matters that are inherently uncertain. Our most critical accounting estimates include:

● the assessment of collectability of accounts receivable, which impacts operating expenses when and if we record bad debt or adjust the allowance for doubtful accounts;  

● the assessment of recoverability of long-lived assets, which impacts gross margin or operating expenses when and if we record asset impairments or accelerate their depreciation;

● the recognition and measurement of current and deferred income taxes (including the measurement of uncertain tax positions), which impact our provision for taxes;

● the valuation of inventory, which impacts gross margin; and

● the recognition and measurement of loss contingencies, which impact gross margin or operating expenses when we recognize a loss contingency, revise the estimate for a loss contingency, or record an asset impairment.

28

We discuss these policies further below, as well as the estimates and judgments involved.

Accounts Receivable / Allowance for Doubtful Accounts / Bad Debt

We assess the collectability of accounts receivable on an ongoing basis and establish an allowance for doubtful accounts when collection is no longer reasonably assured. In establishing the allowance, factors we consider include known troubled accounts, historical experience, age, and other currently available evidence.

Long-Lived Assets

We assess the impairment of long-lived assets when events or changes in circumstances indicate that the carrying value of the assets or the asset grouping may not be recoverable. Factors that we consider in deciding when to perform an impairment review include significant under-performance of a business or product line in relation to expectations, significant negative industry or economic trends, and significant changes or planned changes in our use of the assets. We measure the recoverability of assets that will continue to be used in our operations by comparing the carrying value of the asset grouping to our estimate of the related total future undiscounted net cash flows. If an asset grouping’s carrying value is not recoverable through the related undiscounted cash flows, the asset grouping is considered to be impaired. The impairment is measured by comparing the difference between the asset grouping’s carrying value and its fair value. Long-lived assets such as goodwill, intangible assets, and property, plant and equipment are considered non-financial assets, and are recorded at fair value only if an impairment charge is recognized.

Impairments of long-lived assets are determined for groups of assets related to the lowest level of identifiable independent cash flows. Due to our asset usage model and the interchangeable nature of our ceramic filter manufacturing capacity, we must make subjective judgments in determining the independent cash flows that can be related to specific asset groupings. In addition, as we make manufacturing process conversions and other factory planning decisions, we must make subjective judgments regarding the remaining useful lives of assets, primarily process-specific filter manufacturing tools and building improvements. If we determine that the useful lives of assets are shorter than we had originally estimated, we accelerate the rate of depreciation over the assets’ new, shorter useful lives. During the three months ended March 31, 2013 and 2012, no impairment charge of long-lived assets has been recorded.

Revenue Recognition and Sales Incentives

The Company's 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.

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.

Income Taxes

We must make estimates and judgments in determining the provision for taxes for financial statement purposes. These estimates and judgments occur in the calculation of tax credits, benefits, and deductions, and in the calculation of certain tax assets and liabilities that arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes. Significant changes in these estimates may result in an increase or decrease to our tax provision in a subsequent period.

29

We must assess the likelihood that we will be able to recover our deferred tax assets. If recovery is not likely, we must increase our provision for taxes by recording a valuation allowance against the deferred tax assets that we estimate will not ultimately be recoverable. We believe that we will ultimately recover the deferred tax assets recorded on our consolidated balance sheets. However, should there be a change in our ability to recover our deferred tax assets, our tax provision would increase in the period in which we determined that the recovery was not likely. Recovery of a portion of our deferred tax assets is impacted by management's plans and methods of allocating research and development costs to the underlying reporting units.

The calculation of our tax liabilities involves uncertainties in the application of complex tax regulations in Denmark and the United States. When a tax position is determined uncertain, we recognize liabilities based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. If we determine that a tax position will more likely than not be sustained on audit, the second step requires us to estimate and measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as we have to determine the probability of various possible outcomes. If uncertainties arise we re-evaluate the tax positions on a quarterly basis. This evaluation is based on factors such as changes in facts or circumstances, changes in tax law, new audit activity, and effectively settled issues. Determining whether an uncertain tax position is effectively settled requires judgment. Such a change in recognition or measurement would result in the recognition of a tax benefit or an additional charge to the tax provision.

Inventory

The valuation of inventory requires us to estimate obsolete or excess inventory as well as inventory that is not of saleable quality. The determination of obsolete or excess inventory requires us to estimate the future demand for our products. The estimate of future demand is compared to work-in-process and finished goods inventory levels to determine the amount, if any, of obsolete or excess inventory. As of March 31, 2013, we had total furnace parts and supplies of $1,098,222, raw material of $641,516, work-in-process inventory of $1,587,076, total finished goods inventory of $994,920 and reserve a for obsolescence of $72,102. The estimated future demand is included in the development of our short-term manufacturing plans to enable consistency between inventory valuation and production. Product-specific facts and circumstances reviewed in the inventory valuation process include a review of the customer base, acceptance of the product by the customer and the various environmental authorities, competitor’s products, as well as an assessment of the selling price in relation to the product cost. If our demand forecast for specific products is greater than actual demand, and we fail to reduce manufacturing output accordingly, we could be required to write off inventory, which would negatively impact our gross margin.

In order to determine what costs can be included in the valuation of inventory, we must determine normal capacity at our manufacturing and assembly and test facilities, based on historical production, compared to total available capacity. If the factory production is below the established normal capacity level, a portion of our manufacturing overhead costs would not be included in the cost of inventory, and therefore would be recognized as cost of sales in that period, which would negatively impact our gross margin. We refer to these costs as excess capacity charges. Over the past two years we have experienced no excess capacity charges. We have had to outsource some of the firing of products in order to meet demand.

Loss Contingencies

We are subject to various legal and administrative proceedings and asserted and potential claims, accruals related to product warranties and potential asset impairments (loss contingencies) that arise in the ordinary course of business. An estimated loss from such contingencies is recognized as a charge to income if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Disclosure of a loss contingency is required if there is at least a reasonable possibility that a loss has been incurred. The outcomes of legal and administrative proceedings and claims, and the estimation of product warranties and asset impairments, are subject to significant uncertainty. Significant judgment is required in both the determination of probability and the determination as to whether a loss is reasonably estimable. With respect to estimating the losses associated with repairing and replacing parts in connection with product warranty, we make judgments with respect to customer claim rates. Current warranty estimates are immaterial for accrual or further disclosure. At least quarterly, we review the status of each significant matter, and we may revise our estimates. These revisions could have a material impact on our results of operations and financial position.

Not applicable.

ITEM 4.  CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

Our management, under supervision and with the participation of both of our Chief Executive Officerand Chief Financial Officer, carried out an evaluation of the effectiveness of the design and operation of our “disclosure controls and procedures” (as defined in the Securities Exchange Act of 1934 (the “Exchange Act”) Rules 13a-15(e) and 15-d-15(e)) as of the end of the period covered by this report (the “Evaluation Date”).  Based upon that evaluation, both of our Chief Executive Officer and Chief Financial Officer concluded that as of the Evaluation Date, our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act (i) is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms and (ii) is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

We do not expect that our disclosure controls and procedures will prevent all errors and all instances of fraud. Disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Further, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and the benefits must be considered relative to their costs. Because of the inherent limitations in all disclosure controls and procedures, no evaluation of disclosure controls and procedures can provide absolute assurance that we have detected all our control deficiencies and instances of fraud, if any. The design of disclosure controls and procedures also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.　

(b) Changes in Internal Control over Financial Reporting

There were no changes in our internal controls over financial reporting that occurred during the period covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Translation gains and losses are deferred and accumulated as a component of other comprehensive income in stockholders’ equity. Transaction gains and losses that arose from exchange rate fluctuations from transactions denominated in a currency other than the functional currency are included in the statement of operations as incurred.

Cash and Cash Equivalents -- 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 financial institution in the United States in excess of federally insured amounts at March 31, 2013 and December 31, 2012.

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, 2013 and the year ended December 31, 2012 is as follows:

	2013			2012
Allowance for doubtful accounts at the beginning of the period	$	1,243,500		$	389,032
Bad debt expense		27,925			1,078,365
Amount of receivables written off		-			(248,895	)
Effect of currency translation		(16,500	)		24,998
Allowance for doubtful accounts at the end of the period	$	1,254,925		$	1,243,500

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

Inventory consists of the following at March 31, 2013 and December 31, 2012:

	2013			2012
Furnace parts and supplies	$	588,165		$	529,358
Raw materials		641,516			705,025
Work in process		1,587,076			1,502,144
Finished goods		1,504,977			1,447,855
Reserve for obsolescence		(72,102	)		(72,567	)
Net Inventory	$	4,249,632		$	4,111,815

The Company’s inventory is held as collateral on the Company’s lines of credit.

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 3).

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 an-other-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. 

Revenue Recognition and Sales Incentives -- The Company's 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.

The Company has received various grants from government entities for development and use of silicon carbide membranes in various water filtration and treatment applications. Revenues from 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 grant multiplied by the 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 grants include all direct material and labor costs and those indirect costs related to project. Project costs are capitalized and accreted into cost of sales based on the percentage of the project completed. The Company has never recorded a loss on these projects, 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 $11,788 and $20,447, for the three months ended March 31, 2013 and 2012, respectively.

Research and Development Cost -- The Company expenses research and development costs for the development of new products as incurred. Included in operating expense for the three months ended March 31, 2013 and 2012 were $146,985, and $226,674, 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.

Earnings / (Loss) Per Share -- The Company calculates earnings 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 that have been granted but have not been exercised.

Stock Options -- The Company has granted stock options to certain key employees (See Note 11). During the years presented in the accompanying consolidated financial statements, the Company has granted options. The Company accounts for options in accordance with the provisions of FASB ASC Topic 718, Compensation – Stock Compensation. Non-cash compensation costs of $31,369 and $32,602 have been recognized for the vesting of options granted to employees with an associated recognized tax benefit of $0 for each of the periods ended March 31, 2013 and 2012.

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:

·  Level 1. Observable inputs such as quoted prices in active markets for identical assets or liabilities;

·  Level 2. Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

·  Level 3. Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

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 and liabilities, 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 July 2012, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2012-02, Intangibles-Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment (ASU 2012-02). ASU 2012-02 was issued with the intent of reducing the cost and complexity of performing impairment tests for indefinite-lived intangible assets by providing an entity with the option to first make a qualitative assessment about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it is necessary to perform a quantitative impairment test. The amendments in this update also enhance the consistency of impairment testing guidance among long-lived asset categories by permitting the qualitative assessment, which is similar to the previously updated guidance for goodwill impairment testing provided in ASU 2011-08. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted, including for annual and interim impairment tests performed as of a date before July 27, 2012, if a public entity's financial statements for the most recent annual or interim period have not yet been issued. The Company adopted ASU 2012-02 during the third quarter ended September 30, 2012. Adoption of this standard did not have a material impact on the Company's consolidated financial statements.

NOTE 11 - STOCKHOLDERS' EQUITY

Common Stock

Parent has authorized 100,000,000 shares of common stock, $0.001 par value. As of March 31, 2013 and December 31, 2012, there were 24,111,500 common shares issued and outstanding.

Voting

Holders of Parent common stock are entitled to one vote for each share held of record on each matter submitted to a vote of stockholders, including the election of directors, and do not have any right to cumulate votes in the election of directors.

Dividends

Subject to the rights and preferences of the holders of any series of preferred stock which may at the time be outstanding, holders of Parent common stock are entitled to receive ratably such dividends as our Board of Directors from time to time may declare out of funds legally available.

Liquidation Rights

In the event of any liquidation, dissolution or winding-up of affairs of Parent, after payment of all of our debts and liabilities and subject to the rights and preferences of the holders of any outstanding shares of any series of our preferred stock, the holders of Parent common stock will be entitled to share ratably in the distribution of any of our remaining assets.

 Other Matters

Holders of Parent common stock have no conversion, preemptive or other subscription rights, and there are no redemption rights or sinking fund provisions with respect to the common stock. All of the issued and outstanding shares of common stock on the date of this report are validly issued, fully paid and non-assessable.

Preferred Stock

Our Board of Directors has the authority to issue Parent preferred stock in one or more classes or series and to fix the designations, powers, preferences and rights, the qualifications, limitations or restrictions thereof, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any class or series, without further vote or action by the stockholders. The issuance of Parent preferred stock may have the effect of delaying, deferring or preventing a change in control of us without further action by the stockholders and may adversely affect the voting and other rights of the holders of common stock.

Common Stock Offering

On March 2, 2012, we completed a registered public offering of Parent’s common stock. As part of the closing, we issued 2,511,500 shares of our common stock in a registered direct placement of our shares at a per share price of $3.25. The proceeds net of offering cost received from the closing were approximately $7.1 million.

Common Stock Purchase Warrants

We have outstanding warrants to purchase 6,625,575 shares of Parent common stock, of which 6,500,000 warrants are exercisable for cash at a price of $1.50 per share of common stock and will expire on December 31, 2016 and 125,575 warrants are exercisable for cash at a price of $4.0625 per share of Parent common stock and will expire on March 7, 2017. 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 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 is empowered to grant stock options to employees, officers, and directors of the Company. At March 31, 2013, 1,964,130 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:

	LiqTech International, Inc.
Expected term (Years)		3.0	-	3.5
Volatility		0.07%	-	52.69%
Risk free interest rate		2.33%
Dividend yield		0%

The Company recognized employee stock based compensation expense of $31,369 and $32,602 for the three months ended March 31, 2013 and 2012, respectively. At March 31, 2013 the Company had approximately $94,108 of unrecognized compensation cost related to non-vested options expected to be recognized through December 31, 2013.

A summary of the status of the options outstanding under the Company’s stock option plans at March 31, 2013 is presented below:

			Options Outstanding						Options Exercisable
Range of Exercise Prices			Number Outstanding		Weighted Average Remaining Contractual Life (years)		Weighted Average Exercise Price		Number Exercisable		Weighted Average Exercise Price
$1.50				452,500		1.90	$	1.50		301,667	$	1.50

Exercisable end of period		1,214,420	$	2.67		1.90	$	507,250

At March 31, 2013 the Company had 749,710 non-vested options with a weighted average exercise price of $2.74 and with a weighted average grant date fair value of $0.18, resulting in unrecognized compensation expense of $94,108, which is expected to be expensed over a weighted-average period of 0.75 years.

The total intrinsic value of options exercised during the three months ended March 31, 2013 was $507,250. Intrinsic value is measured using the fair market value at the date of exercise (for shares exercised) or at March 31, 2013 (for outstanding options), less the applicable exercise price.

Note 9 - Income Taxes

Income Tax Disclosure [Text Block]

 NOTE 9 – 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.

The temporary differences, tax credits and carry forwards gave rise to the following deferred tax asset (liabilities) at March 31, 2013 and December 31, 2012:

	2013			2012
Vacation accrual	$	4,093		$	4,093
Allowance for doubtful Accounts		243,314			243,314
Reserve for obsolete inventory		19,925			19,925
Net current tax assets	$	267,332		$	267,332
Business tax credit carryover		25,379			25,379
Net operating loss carryover		1,139,923			856,517
Excess of book over tax depreciation		(802,797	)		(805,949	)
Net deferred tax liability	$	(362,505	)	$	(75,947	)

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 meet 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%.

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 can difficult to determine and can only be estimated. Management estimates that it is more likely than not that the Company will generate adequate net profits to use the deferred tax assets; management has estimated that all of the deferred tax will be realized and consequently, a valuation allowance was not recorded.

As of March 31, 2013, the Company had net operating loss carryovers of approximately $2,100,000 for U.S. Federal purposes expiring through 2033, approximately $317,000 for Danish Tax purposes which do not expire, $63,000 for German tax purposes which do not expire and $45,000 for Singapore tax purposes which do not expire.

A reconciliation of income tax expense at the federal statutory rate to income tax expense at the Company’s effective rate was as follows at March 31, 2013 and 2012:

	2013			2012
Computed tax at expected statutory rate	$	(328,670	)	$	147,417
State and local income taxes, net of federal benefits		-			6,945
Non-deductible expenses		-			849
Non-US income taxed at different rates		31,806			(34,477	)
Manufacture and other tax credits		-			(13,600	)
Other items		-			3,842
Income tax expense	$	(296,864	)	$	110,977

The components of income tax expense (benefit) from continuing operations for the years ended March 31, 2013 and 2012 consisted of the following:

	2013		2012
Current income tax expense:
Danish	$	-	$	120,107
Federal		-		60,600
State		-		2,779
Current tax expense	$	-	$	183,486

Deferred tax expense (benefit) arising from:
Excess of tax over financial accounting depreciation	$	-		$	43,766
Net operating loss carryover		(296,864	)		(87,021	)
Allowance for doubtful accounts		-			(10,504	)
Reserve for obsolete inventory		-			(18,750	)
Deferred tax expense	$	(296,864	)	$	(72,509	)
Income Tax Expense (Benefit)	$	(296,864	)	$	110,977

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

The Company files Danish  and U.S. federal, and Minnesota state income tax returns, and LiqTech AS and LiqTech International AS are generally no longer subject to tax examinations for years prior to 2007 for their Danish tax returns.  LiqTech NA is generally no longer subject to tax examinations for years prior to 2008 for U.S. federal and U.S. states tax returns.

Property, Plant and Equipment, Policy [Policy Text Block]

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 3).

Investment, Policy [Policy Text Block]

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 an-other-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.

Goodwill and Intangible Assets, Policy [Policy Text Block]

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.

Revenue Recognition, Policy [Policy Text Block]

Revenue Recognition and Sales Incentives -- The Company's 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.

The Company has received various grants from government entities for development and use of silicon carbide membranes in various water filtration and treatment applications. Revenues from 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 grant multiplied by the 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 grants include all direct material and labor costs and those indirect costs related to project. Project costs are capitalized and accreted into cost of sales based on the percentage of the project completed. The Company has never recorded a loss on these projects, 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 Costs, Policy [Policy Text Block]

Advertising Cost -- Cost incurred in connection with advertising of the Company’s products is expensed as incurred. Such costs amounted to $11,788 and $20,447, for the three months ended March 31, 2013 and 2012, respectively.

Research, Development, and Computer Software, Policy [Policy Text Block]

Research and Development Cost -- The Company expenses research and development costs for the development of new products as incurred. Included in operating expense for the three months ended March 31, 2013 and 2012 were $146,985, and $226,674, respectively, of research and development costs.

Income Tax, Policy [Policy Text Block]

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.

Earnings Per Share, Policy [Policy Text Block]

Earnings / (Loss) Per Share -- The Company calculates earnings 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 that have been granted but have not been exercised.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Stock Options -- The Company has granted stock options to certain key employees (See Note 11). During the years presented in the accompanying consolidated financial statements, the Company has granted options. The Company accounts for options in accordance with the provisions of FASB ASC Topic 718, Compensation – Stock Compensation. Non-cash compensation costs of $31,369 and $32,602 have been recognized for the vesting of options granted to employees with an associated recognized tax benefit of $0 for each of the periods ended March 31, 2013 and 2012.

Fair Value Measurement, Policy [Policy Text Block]

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:

·  Level 1. Observable inputs such as quoted prices in active markets for identical assets or liabilities;

·  Level 2. Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

·  Level 3. Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

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.

Use of Estimates, Policy [Policy Text Block]

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 and liabilities, 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.

New Accounting Pronouncements, Policy [Policy Text Block]

Recent Accounting Pronouncements

In July 2012, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2012-02, Intangibles-Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment (ASU 2012-02). ASU 2012-02 was issued with the intent of reducing the cost and complexity of performing impairment tests for indefinite-lived intangible assets by providing an entity with the option to first make a qualitative assessment about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it is necessary to perform a quantitative impairment test. The amendments in this update also enhance the consistency of impairment testing guidance among long-lived asset categories by permitting the qualitative assessment, which is similar to the previously updated guidance for goodwill impairment testing provided in ASU 2011-08. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted, including for annual and interim impairment tests performed as of a date before July 27, 2012, if a public entity's financial statements for the most recent annual or interim period have not yet been issued. The Company adopted ASU 2012-02 during the third quarter ended September 30, 2012. Adoption of this standard did not have a material impact on the Company's consolidated financial statements.
