Note 1 – Organization and Description of Business | |
ClearSign Combustion Corporation (ClearSign or the Company) is a development stage company located in Seattle, Washington and incorporated in the state of Washington on January 23, 2008. The Company was formed to design, develop and market technologies that improve both the energy efficiency and emission control characteristics of combustion systems. The Company’s primary technologies include its Electrodynamic Combustion Control™ or ECC™ technology, which introduces a computer-controlled electric field into the combustion region which may better control gas-phase chemical reactions and improve system performance and cost-effectiveness, and its Duplex™ technology, which achieves very low emissions without the need of external flue gas recirculation, selective catalytic reduction, or higher excess air operation. | |
As a development stage company, the Company has generated limited revenues from operations to date to meet its operating expenses, and has historically financed its operations primarily through issuances of equity securities. The Company has incurred losses since its inception totaling $13,964,000 and expects to experience operating losses and negative cash flow for the foreseeable future. Management believes that the successful growth and operation of the Company’s business is dependent upon its ability to obtain adequate sources of funding through co-development agreements, strategic partnering agreements, or equity or debt financing to adequately support research and development efforts, protect intellectual property, form relationships with strategic partners, and provide for working capital and general corporate purposes. There can be no assurance that the Company will be successful in achieving its long-term plans as set forth above, or that such plans, if consummated, will enable the Company to obtain profitable operations or continue in the long-term as a going concern. | |

Note 2 – Summary of Significant Accounting Policies | |
Development Stage Enterprise | |
The Company is a development stage company as defined in Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 915, Development Stage Entities. The Company is devoting substantially all of its present efforts to design and develop new technologies in combustion systems and its planned principal operations have not yet commenced. The Company has not generated any significant revenues from operations and has no assurance of any future revenues. All losses accumulated since January 23, 2008 have been considered as part of the Company's development stage activities. | |
Use of Estimates | |
The preparation of financial statements in conformity with accounting principles generally accepted in the United States (US GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. | |
Revenue Recognition | |
The Company recognizes revenue on co-development agreements using the percentage of completion method. Under this method, the completion percentage is determined by dividing costs incurred to date by total estimated project costs. Since these projects will require technological development to complete, which by its nature is difficult to predict, the actual cost required to complete contracted work may vary from estimates. Estimated project costs are revised regularly which can alter the reported level of project profitability. Any estimated project losses are recognized in the current reporting period. Customer billings are recorded when cash receipts are probable and in accordance with the underlying co-development contract. If billings exceed recognized revenue, the difference is recorded as a current liability, while any recognized revenues exceeding billings are recorded as a current asset. Recognized revenues are subject to revisions as the contract progresses to completion and actual revenue and cost become certain. Revisions in revenue estimates are reflected in the period in which the facts that give rise to the revision become known. | |
Cost of Revenue | |
Cost of co-development revenue includes both direct and allocated indirect costs of completing the scope of work of co-development agreements. Direct costs include labor, materials and other costs incurred directly in fulfilling co-development agreements. Indirect costs include labor, rent, depreciation and other costs associated with operating the Company. Due to the nature of the work involved, the cost of co-development projects may fluctuate substantially from period to period. | |
Cash and Cash Equivalents | |
Highly liquid investments purchased with an original maturity of three months or less are considered cash equivalents. Cash is maintained with a commercial bank where accounts are generally guaranteed by the Federal Deposit Insurance Corporation up to $250,000. The Company’s deposits exceed this limit. The Company has not experienced losses in such accounts and believes it is not exposed to any significant credit risk on cash and cash equivalents. | |
Fixed Assets | |
Fixed assets are recorded at cost. Depreciation is computed using the straight-line method over the estimated lives of the respective assets. Leasehold improvements are depreciated over the life of the lease or their useful life, whichever is shorter. All other fixed assets are depreciated over three to four years. Maintenance and repairs are expensed as incurred. | |
Patents and Trademarks | |
Patents and trademarks are recorded at cost. Amortization is computed using the straight-line method over the estimated useful lives of the assets once they are awarded, which has not yet occurred. | |
Impairment of Long-Lived Assets | |
The Company tests long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable through the estimated undiscounted cash flows expected to result from the use and eventual disposition of the assets. In that event, a loss is recognized based on the amount by which the carrying amount exceeds the fair value of the long-lived assets. Loss on long-lived assets to be disposed of is determined in a similar manner, except that fair values are reduced for the cost of disposal. During 2013, the Company recorded an impairment loss of $4,000 from abandonment of a capitalized patent. As of December 31, 2012, the Company determined that there was no impairment. | |
Fair Value of Financial Instruments | |
Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are categorized based on whether or not the inputs are observable in the market and the degree that the inputs are observable. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. | |
The Company's financial instruments primarily consist of cash and cash equivalents, accounts payable and accrued expenses. As of the balance sheet dates, the estimated fair values of the financial instruments were not materially different from their carrying values as presented on the balance sheets. This is primarily attributed to the short maturities of these instruments. The Company did not identify any other non-recurring assets and liabilities that are required to be presented in the balance sheets at fair value. | |
Research and Development | |
The cost of research and development is expensed as incurred. Research and development costs consist of salaries, benefits, share based compensation, consulting fees, rent, utilities, depreciation, and consumables. | |
Deferred Rent | |
Operating lease agreements which contain provisions for future rent increases or periods in which rent payments are reduced or abated are recorded in monthly rent expense in the amount of the total payments over the lease term divided by the number of months of the lease term. The difference between rent expense recorded and the amount paid is credited or charged to deferred rent which is reflected on the accompanying balance sheet. | |
Income Taxes | |
The Company accounts for income taxes using an asset and liability approach which allows for the recognition and measurement of deferred tax assets based upon the likelihood of realization of tax benefits in future years. Under the asset and liability approach, deferred taxes are provided for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided for deferred tax assets if it is more likely than not these items will either expire before the Company is able to realize their benefits, or that future deductibility is uncertain. | |
Tax benefits from an uncertain tax position are recognized only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate resolution. | |
Stock-Based Compensation | |
The costs of all employee stock options, as well as other equity-based compensation arrangements, are reflected in the financial statements based on the estimated fair value of the awards on the grant date. That cost is recognized over the period during which an employee is required to provide service in exchange for the award. Stock compensation for stock granted to non-employees is determined as the fair value of the consideration received or the fair value of equity instruments issued, whichever is more reliably measured. | |
Net Loss per Common Share | |
Basic loss per share is computed by dividing loss available to common stockholders by the weighted-average number of common shares outstanding. Diluted loss per share is computed similar to basic loss per share except that the denominator is increased to include additional common shares available upon exercise of stock options and warrants using the treasury stock method, except for periods for which no common share equivalents are included because their effect would be anti-dilutive. Potentially dilutive shares outstanding amounted to 1,109,724 and 920,743 at December 31, 2013 and 2012, respectively. | |
Recently Issued Accounting Pronouncements | |
Management does not believe that any recently issued, but not yet effective standards, if adopted, will have a material effect on the financial statements. | |
Emerging Growth Company | |
The Company is an emerging growth company as defined under the Jumpstart Our Business Startups Act of 2012 (JOBS Act). An emerging growth company may delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The Company will remain an emerging growth company until December 31, 2017, although it will lose that status sooner if its revenues exceed $1 billion, if it issues more than $1 billion in non-convertible debt in a three year period, or if the market value of its common stock that is held by non-affiliates exceeds $700 million as of any June 30. At June 30, 2013, the market value of the Company’s common stock that is held by non-affiliates totaled $60 million. | |

Note 5 – Income Taxes | ||||||||
Through December 31, 2013, the Company incurred net operating losses for federal tax purposes of approximately $14,100,000. The net operating loss carry forward may be used to reduce taxable income through the years 2028 to 2033. The availability of the Company's net operating loss carry forward is subject to limitation if there is a 50% or more change in the ownership of the Company's stock. | ||||||||
A reconciliation of the expected tax computed at the statutory federal income tax rate to the provision for income taxes is as follows: | ||||||||
2013 | 2012 | |||||||
Expected tax benefit at 34% | $ | -1,797,000 | $ | -1,424,000 | ||||

Provision for income taxes | $ | - | $ | - | ||||
The net deferred tax asset at December 31, 2013 and 2012 was $4,795,000 and $3,075,000, respectively. A 100% valuation allowance has been established against the deferred tax assets as the utilization of the loss carry forward cannot reasonably be assured. Significant components of the deferred tax assets (liabilities), computed at the statutory federal tax rate of 34%, are approximately as follows: | ||||||||

The Company is authorized to issue 62,500,000 shares of common stock and 2,000,000 shares of preferred stock. Preferences, limitations, voting powers and relative rights of any preferred stock to be issued may be determined by the Company’s Board of Directors. The Company has not issued any shares of preferred stock. | ||||||||||||||||
In April and May 2012, the Company completed an initial public offering (IPO) whereby 3,450,000 shares of common stock were issued at $4.00 per share, which included the exercise of the overallotment allowance by the underwriter, MDB Capital Group, LLC (MDB). Gross proceeds from the IPO totaled $13.8 million and net cash proceeds approximated $11.2 million. Expenses of the offering approximated $2.7 million, including underwriter fees of $1.2 million paid to MDB along with a warrant to purchase 345,000 shares of ClearSign’s common stock at $5.00 per share exercisable from April 2013 to April 2017 valued at $128,000, qualified independent underwriter fees of $110,000, underwriter legal fees of $125,000, underwriter expenses of $35,000, and issuer legal fees of $822,000, which was paid in part through the issuance of 110,000 shares of the Company’s common stock to its legal counsel at a price of $4.00 per share. | ||||||||||||||||
As described in Note 10, the Company completed a $6.5 million registered direct offering of common stock in March 2014. | ||||||||||||||||
Equity Incentive Plan | ||||||||||||||||
The Company has an Equity Incentive Plan which provides for the granting of options to purchase shares of common stock, stock awards to purchase shares at no less than 85% of the value of the shares, and stock bonuses to officers, employees, board members, certain consultants, and advisors. The Compensation Committee of the Board of Directors is authorized to administer the Equity Incentive Plan and establish the grant terms, including the grant price, vesting period and exercise date. As of December 31, 2013, the number of shares reserved for issuance under the Equity Incentive Plan totaled 991,300 shares. The Equity Incentive Plan provides for quarterly increases in the available number of authorized shares equal to the lesser of 10% of any new shares issued by the Company during the quarter immediately prior to the adjustment date or such lesser amount as the Board of Directors shall determine. Activity under the Equity Incentive Plan is as follows: | ||||||||||||||||

Stock Options | ||||||||||||||||
In 2013, the Company granted to certain employees 203,990 and 2,400 stock options at an exercise prices of $4.88 per share and $7.33 per share, respectively, under the Equity Incentive Plan. The stock options were issued at the grant date fair value for a contractual life of 10 years and vest over four years. As permitted by SAB 107, due to the Company’s insufficient history of option activity, management utilized the simplified approach to estimate the options’ expected term, which represents the period of time that options granted are expected to be outstanding. Expected volatility was determined through the average of a peer group of public companies. The Company estimated the forfeiture rate at the time of grant and will revise it, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company recognizes compensation costs only for those equity awards expected to vest. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield in effect at the time of grant. The Company has never declared or paid dividends and has no plans to do so in the foreseeable future. The Company did not grant stock options in 2012. | ||||||||||||||||
The following weighted-average assumptions were utilized in the calculation of the fair value of the stock options: | ||||||||||||||||
Expected life | 6.25 years | |||||||||||||||

In 2013 and 2012, the Company granted 30,000 and 20,799 shares, respectively, of common stock under the Equity Incentive Plan to its three independent directors in accordance with agreements for service on the board. The fair value of the stock at the time of grant was $5.00 and $4.94 per share for a total value of $150,000 and $103,000 which the Company recognized in general and administrative expense in 2013 and 2012, respectively. | ||||||||||||||||
In 2011, the Company granted 125,000 shares of stock under the Equity Incentive Plan to a key employee which are subject to declining repurchase rights by the Company at $0.0001 per share should the employee terminate employment or upon other related circumstances prior to June 30, 2015. The fair value of the stock at the time of grant was $2.20 per share for a total value of $275,000. After the repurchase rights had expired on 62,500 shares, the Company terminated the remaining stock grant agreement in December 2012 and issued a new stock grant for 62,500 shares of which 2,500 shares were vested immediately. The new stock grant is subject to declining repurchase rights by the Company on 60,000 shares at $0.0001 per share should the employee terminate employment or upon other related circumstances prior to September 30, 2016. The Company recognized general and administrative compensation expense of $31,000 and $96,000 in 2013 and 2012, respectively, and $202,000 for the period from inception (January 23, 2008) to December 31, 2013.

The Company’s officers, employees, and board members are not entitled to receive grants from the Consultant Plan. The Compensation Committee of the Board of Directors is authorized to administer the Consultant Plan and establish the grant terms. The number of shares reserved for issuance under the Consultant Plan on the date of adoption of May 2, 2013 totaled 75,000 shares.

Summary of Significant Accounting Policies (Policies) | 12 Months Ended |
Dec. 31, 2013 | |
Accounting Policies [Abstract] | ' |
Development Stage Enterprise Policy [Policy Text Block] | ' |
Development Stage Enterprise | |
The Company is a development stage company as defined in Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 915, Development Stage Entities. The Company is devoting substantially all of its present efforts to design and develop new technologies in combustion systems and its planned principal operations have not yet commenced. The Company has not generated any significant revenues from operations and has no assurance of any future revenues. All losses accumulated since January 23, 2008 have been considered as part of the Company's development stage activities. | |
Use Of Estimates, Policy [Policy Text Block] | ' |
Use of Estimates | |
The preparation of financial statements in conformity with accounting principles generally accepted in the United States (US GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. | |
Revenue Recognition, Policy [Policy Text Block] | ' |
Revenue Recognition | |
The Company recognizes revenue on co-development agreements using the percentage of completion method. Under this method, the completion percentage is determined by dividing costs incurred to date by total estimated project costs. Since these projects will require technological development to complete, which by its nature is difficult to predict, the actual cost required to complete contracted work may vary from estimates. Estimated project costs are revised regularly which can alter the reported level of project profitability. Any estimated project losses are recognized in the current reporting period. Customer billings are recorded when cash receipts are probable and in accordance with the underlying co-development contract. If billings exceed recognized revenue, the difference is recorded as a current liability, while any recognized revenues exceeding billings are recorded as a current asset. Recognized revenues are subject to revisions as the contract progresses to completion and actual revenue and cost become certain. Revisions in revenue estimates are reflected in the period in which the facts that give rise to the revision become known. | |
Cost of Sales, Policy [Policy Text Block] | ' |
Cost of Revenue | |
Cost of co-development revenue includes both direct and allocated indirect costs of completing the scope of work of co-development agreements. Direct costs include labor, materials and other costs incurred directly in fulfilling co-development agreements. Indirect costs include labor, rent, depreciation and other costs associated with operating the Company. Due to the nature of the work involved, the cost of co-development projects may fluctuate substantially from period to period. | |
Cash and Cash Equivalents, Policy [Policy Text Block] | ' |
Cash and Cash Equivalents | |
Highly liquid investments purchased with an original maturity of three months or less are considered cash equivalents. Cash is maintained with a commercial bank where accounts are generally guaranteed by the Federal Deposit Insurance Corporation up to $250,000. The Company’s deposits exceed this limit. The Company has not experienced losses in such accounts and believes it is not exposed to any significant credit risk on cash and cash equivalents. | |
Fixed Assets Policy [Policy Text Block] | ' |
Fixed Assets | |
Fixed assets are recorded at cost. Depreciation is computed using the straight-line method over the estimated lives of the respective assets. Leasehold improvements are depreciated over the life of the lease or their useful life, whichever is shorter. All other fixed assets are depreciated over three to four years. Maintenance and repairs are expensed as incurred. | |
Patents and Trademarks Policy [Policy Text Block] | ' |
Patents and Trademarks | |
Patents and trademarks are recorded at cost. Amortization is computed using the straight-line method over the estimated useful lives of the assets once they are awarded, which has not yet occurred. | |
Impairment Of Long Lived Asset Policy [Policy Text Block] | ' |
Impairment of Long-Lived Assets | |
The Company tests long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable through the estimated undiscounted cash flows expected to result from the use and eventual disposition of the assets. In that event, a loss is recognized based on the amount by which the carrying amount exceeds the fair value of the long-lived assets. Loss on long-lived assets to be disposed of is determined in a similar manner, except that fair values are reduced for the cost of disposal. During 2013, the Company recorded an impairment loss of $4,000 from abandonment of a capitalized patent. As of December 31, 2012, the Company determined that there was no impairment. | |
Fair Value Of Financial Instruments, Policy [Policy Text Block] | ' |
Fair Value of Financial Instruments | |
Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are categorized based on whether or not the inputs are observable in the market and the degree that the inputs are observable. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. | |
The Company's financial instruments primarily consist of cash and cash equivalents, accounts payable and accrued expenses. As of the balance sheet dates, the estimated fair values of the financial instruments were not materially different from their carrying values as presented on the balance sheets. This is primarily attributed to the short maturities of these instruments. The Company did not identify any other non-recurring assets and liabilities that are required to be presented in the balance sheets at fair value. | |
Research and Development Expense, Policy [Policy Text Block] | ' |
Research and Development | |
The cost of research and development is expensed as incurred. Research and development costs consist of salaries, benefits, share based compensation, consulting fees, rent, utilities, depreciation, and consumables. | |
Deferred Rent Policy [Policy Text Block] | ' |
Deferred Rent | |
Operating lease agreements which contain provisions for future rent increases or periods in which rent payments are reduced or abated are recorded in monthly rent expense in the amount of the total payments over the lease term divided by the number of months of the lease term. The difference between rent expense recorded and the amount paid is credited or charged to deferred rent which is reflected on the accompanying balance sheet. | |
Income Tax, Policy [Policy Text Block] | ' |
Income Taxes | |
The Company accounts for income taxes using an asset and liability approach which allows for the recognition and measurement of deferred tax assets based upon the likelihood of realization of tax benefits in future years. Under the asset and liability approach, deferred taxes are provided for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided for deferred tax assets if it is more likely than not these items will either expire before the Company is able to realize their benefits, or that future deductibility is uncertain. | |
Tax benefits from an uncertain tax position are recognized only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate resolution. | |
Share-Based Compensation, Option and Incentive Plans Policy [Policy Text Block] | ' |
Stock-Based Compensation | |
The costs of all employee stock options, as well as other equity-based compensation arrangements, are reflected in the financial statements based on the estimated fair value of the awards on the grant date. That cost is recognized over the period during which an employee is required to provide service in exchange for the award. Stock compensation for stock granted to non-employees is determined as the fair value of the consideration received or the fair value of equity instruments issued, whichever is more reliably measured. | |
Earnings Per Share, Policy [Policy Text Block] | ' |
Net Loss per Common Share | |
Basic loss per share is computed by dividing loss available to common stockholders by the weighted-average number of common shares outstanding. Diluted loss per share is computed similar to basic loss per share except that the denominator is increased to include additional common shares available upon exercise of stock options and warrants using the treasury stock method, except for periods for which no common share equivalents are included because their effect would be anti-dilutive. Potentially dilutive shares outstanding amounted to 1,109,724 and 920,743 at December 31, 2013 and 2012, respectively. | |
New Accounting Pronouncements, Policy [Policy Text Block] | ' |
Recently Issued Accounting Pronouncements | |
Management does not believe that any recently issued, but not yet effective standards, if adopted, will have a material effect on the financial statements. | |
Growing Company [Policy Text Block] | ' |
Emerging Growth Company | |
The Company is an emerging growth company as defined under the Jumpstart Our Business Startups Act of 2012 (JOBS Act). An emerging growth company may delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The Company will remain an emerging growth company until December 31, 2017, although it will lose that status sooner if its revenues exceed $1 billion, if it issues more than $1 billion in non-convertible debt in a three year period, or if the market value of its common stock that is held by non-affiliates exceeds $700 million as of any June 30. At June 30, 2013, the market value of the Company’s common stock that is held by non-affiliates totaled $60 million. | |
