Notes to Financial Statements (unaudited)

1. Organization and Operations

Integrated Surgical Systems, Inc. (the “Company”) was incorporated in Delaware in 1990 to design, manufacture, sell and service image-directed, computer-controlled robotic software and hardware products for use in orthopedic surgical procedures.  On June 28, 2007, the Company completed the sale of substantially all of its operating assets.  After completion of the sale, the Company no longer engaged in any business activities related to its former business described above. The Company’s current operations are limited to raising additional funds to be used to maintain the Company’s public company status and to complete a business combination or strategic alliance, if suitable candidates are identified.

2. Significant Accounting Policies

Basis of Presentation

The accompanying unaudited financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial statements and with the rules and regulations under Regulation S-X of the Securities and Exchange Commission for Form 10-Q. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statement presentation. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary to present fairly the financial position as of September 30, 2013, the results of operations and cash flows for the nine months then ended have been included. These financial statements should be read in conjunction with the financial statements of the Company and the Company’s management discussion and analysis included in the Company’s Form 10-K for the year ended December 31, 2012. Interim results are not necessarily indicative of the results for a full year.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses for the reporting period.  Actual results could differ from those estimates.

Cash and cash equivalents

Cash and cash equivalents include checking and money market accounts held in two financial institutions. The Company has a checking account at one institution with a balance of approximately $22,000 at September 30, 2013. The funds in this account are fully guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. The Company has a money market account in a brokerage account with a second financial institution, with a money market cash balance of approximately $50,000 at September 30, 2013. Assets in this brokerage account are protected by the Securities Investor Protection Corporation (“SIPC”) up to $500,000.  The Company had no uninsured cash and cash equivalents at September 30, 2013.

Stock-Based Compensation

Compensation costs for stock, warrants or options issued to employees and non-employees are based on the fair value method and accounted for in accordance with FASB ASC 718, “ Compensation – Stock Compensation .”  The value of warrants and options are calculated using a Black-Scholes Model, using the market price of the Company’s common stock on the date of issuance for the employee options and the date of commitment for non-employee options, an expected dividend yield of zero, the expected life of the warrants or options and the expected volatility of the Company’s common stock.

8

Investment in Available-for-Sale Securities

The Company has a portfolio of investments in available-for-sale debt securities, which consist of fixed income debt securities and equity securities, which are accounted for in accordance with FASB ASC 320, “Investments - Debt and Equity Securities.”  Management determines the appropriate classification of the securities at the time they are acquired and evaluates the appropriateness of such classifications at each balance sheet date.  Available-for-sale securities are stated at fair value, and unrealized holding gains and losses, net of the related deferred tax effect, if any, are reported as other comprehensive income, a separate component of stockholders’ equity.

Fair Value Measurement

FASB ASC 820“Fair Value Measurements and Disclosures” clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, FASB ASC 820 establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

· Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

· Level 2 - Include other inputs that are directly or indirectly observable in the marketplace.

· Level 3 - Unobservable inputs which are supported by little or no market activity.

The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

In accordance with FASB ASC 820, the Company measures its cash equivalents, investments in available-for-sale securities, and derivative liability at fair value. The Company’s cash equivalents and investments in available-for-sale securities are classified within Level 1 by using quoted market prices. The Company’s derivative liability is classified within Level 3.

The carrying value of other current assets and liabilities are considered to be representative of their respective fair values because of the short-term nature of those instruments.

Income Taxes

Deferred income taxes have been provided for temporary differences between financial statement and income tax reporting under the liability method, using expected tax rates and laws that are expected to be in effect when the differences are expected to reverse.  A valuation allowance is provided when realization is not considered more likely than not.

The Company applies the provisions of FASB ASC 740, “Income Taxes.”  ASC 740 clarifies the accounting for uncertainty in income taxes recognized in the Company’s financial statements in accordance with ASC 740, “Income Taxes,” and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

The Company’s policy is to classify expenses as a result of income tax assessments as interest expense for interest charges and as penalties in general and administrative expenses for penalty assessments.

9

Cost-Basis Method Valuation

The Company’s non-marketable equity investment was previously recorded using the cost-basis method of accounting, and was classified as a long-term asset on the accompanying balance sheet as permitted by FASB ASC 325, “Cost Method Investments”, as the Company owned less than 20% of the voting securities and did not have the ability to exercise significant influence over operating and financial policies of the entity. In 2012, the Company distributed a majority of this investment to its stockholders and reclassified the remaining shares as available-for-sale securities. During the same period, the investee’s stock became publicly traded and its fair value became readily available. Therefore, these shares have been accounted for in accordance with FASB ASC 320, “Investment – Debt and Equity Securities”.   See Note 5, “Investment in ClearSign” for more information. The remaining shares were sold during the three months ended June 30, 2013.

Recently Adopted Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2011-04, “Fair Value Measurement” (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs. This guidance amends the disclosure requirements related to recurring and nonrecurring fair value measurements and includes the following provisions:  application of the concepts of highest and best use and valuation premise, introduction of an option to measure groups of offsetting assets and liabilities on a net basis, incorporation of certain premiums and discounts in fair value measurements, and the measurement of fair value of certain instruments classified in shareholders’ equity. In addition, the amended guidance includes several new fair value disclosure requirements, including, among other things, information about valuation techniques and unobservable inputs used in Level 3 fair value measurements and a narrative description of Level 3 measurements’ sensitivity to changes in unobservable inputs. The guidance became effective for the reporting period beginning January 1, 2012. The adoption of this guidance did not have a material impact on the Company’s financial statements.

In June 2011, the FASB issued Accounting Standards Update 2011-05, “Comprehensive Income” (Topic 220): Presentation of Comprehensive Income. This amended guidance eliminates the option for reporting entities to present components of other comprehensive income in the statement of stockholders’ equity. Instead, this amended guidance now requires reporting entities to present all non-owner changes in stockholders’ equity either as a single continuous statement of comprehensive income or as two separate but consecutive statements. The guidance became effective for the reporting period beginning January 1, 2012. The adoption of this guidance did not have a material impact on the Company’s financial statements.

Recently Announced Accounting Pronouncements

In July 2013, the FASB issued Accounting Standards Update 2013-11, “Income Taxes” (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This amended guidance will require an unrecognized tax benefit, or a portion of an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The guidance will become effective for the reporting period beginning January 1, 2014. The adoption of this guidance is not estimated to have a material impact on the Company’s financial statements.

Management does not believe that any other recently issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying financial statements.

3.  Income (Loss) Per Share

Basic income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period plus dilutive common stock equivalents, using the treasury stock method.

Common stock equivalents for convertible preferred stock of 1,158,845 and 1,217,457 shares were excluded from the calculation of loss per share for the nine months ended September 30, 2013 and the three months ended September 30, 2013, respectively, because they were not dilutive; these shares would have been dilutive if the Company had not had a net loss for the this period. Common stock equivalents for convertible preferred stock of 991,153 shares were included in calculation of gain per share for the nine months and three months ended September 30, 2012.

10

A warrant for 30,000 shares was excluded from the calculation of loss per share for the nine months and three months ended September 30, 2013, and a warrant for 30,000 shares, and stock options of 100,000 were excluded from the calculation of income (loss) per share for the nine months and three months ended September 30, 2012, respectively, because their effect was anti-dilutive.

4.  Investments in Available-for-Sale Securities

The following is a summary of the Company’s investment in available-for-sale securities as of September 30, 2013:

	Cost		Unrealized Gains		Unrealized Losses		Fair Value
U.S. federal agency securities	$	90,778	$	129	$	(339)	$	90,568

	$	2,589,097	$	15,882	$	(23,711)	$	2,581,268

The following is a summary of the Company’s investment in available-for-sale securities as of December 31, 2012:

	Cost		Unrealized Gains		Unrealized Losses		Fair Value
U.S. federal agency securities	$	19,592	$	196	$	-	$	19,788
Municipal securities		1,154,841		2,882		(2,090)		1,155,633
Certificates of deposit		1,193,494		8,734		(16,904)		1,185,324
Corporate debt securities		285,524		4,164		(9,633)		280,055
Equity securities – ClearSign common stock		7,905		9,485		-		17,390
	$	2,661,356	$	25,461	$	(28,627)	$	2,658,190

The Company’s investment portfolio had a net realized loss of $3,419 and $1,231 for the nine months ended September 30, 2013 and 2012, respectively. The Company’s investment portfolio had a net realized loss of $14,511 and $89 for the three months ended September 30, 2013 and 2012, respectively.

The cost and fair value of investments in available-for-sale securities, by contractual maturity, as of September 30, 2013, were as follows:

	Cost		Fair Value
Due within one year	$	528,115	$	526,184
Due after one year through three years		1,045,080		1,042,919
Due after three years		1,015,902		1,012,165
	$	2,589,097	$	2,581,268

Expected maturities will differ from contractual maturities because the issuers of certain debt securities have the right to call or prepay their obligations without any penalties. Accordingly, the Company has classified the entire fair value of its investments in available-for-sale securities as current assets in the accompanying balance sheets.

5.  Cost-Basis Investment

On April 20, 2011, the Company purchased 363,636 shares of common stock of ClearSign Combustion Corporation, a privately-held Washington corporation (“ClearSign”), for an aggregate purchase price of $1,000,000, or $2.75 per share, in connection with ClearSign’s private offering of up to $3,000,000 of its common stock (the “ClearSign Offering”). Due to a 1.25-for-one stock split, which occurred subsequent to this purchase, the Company held 454,545 shares of common stock of ClearSign. Prior to June 30, 2012, this investment had been accounted for using the cost method, as the Company owned less than 20% of the voting securities and did not have the ability to exercise significant influence over operating and financial policies of the entity. 

11

ClearSign filed a registration statement on Form S-1 (as amended) for the initial public offering of its common stock that was declared effective April 24, 2012. On April 25, 2012, ClearSign Combustion Corporation (“ClearSign”) completed an initial public offering selling 3,000,000 shares of its common stock at $4.00 per share, and trading under the symbol CLIR on NASDAQ. The shares of common stock of ClearSign previously acquired in a private placement by the Company were registered for resale or distribution as part of the offering.

On April 24, 2012, the Company’s board of directors declared a dividend to the shareholders of the Company, of an aggregate of 450,000 shares of common stock of ClearSign. The dividend was at the rate of 0.05513475 shares of ClearSign for each share of common stock of the Company, which equates to one share of common stock of ClearSign for approximately 18.137 shares of the Company’s common stock. The record date of the dividend was May 9, 2012, and the payment date of the dividend was May 23, 2012. A total of 450,952 shares of ClearSign were distributed, including 952 rounding shares. In 2012, the Company recorded a gain of $811,713 equal to the increase in the fair value of the ClearSign investment which had been distributed, or $1,803,808, as measured on April 25, 2012 less the cost basis of the investment.

The Company retained 3,593 shares of ClearSign common stock, which were then sold on April 29, 2013. A realized gain of $24,475 was recorded during the nine months ended September 30, 2013.

6.  Redeemable Convertible Preferred Stock

The Company’s Certificate of Incorporation authorized 1,000,000 shares of undesignated, serial preferred stock. Preferred stock may be issued from time to time in one or more series. The Board of Directors is authorized to determine the rights, preferences, privileges, and restrictions granted to and imposed upon any wholly unissued series of preferred stock and designation of any such series without any further vote or action by the Company’s stockholders.

As of September 30, 2013 and December 31, 2012, the Company’s only outstanding series of convertible preferred stock is the Series G Convertible Preferred Stock (“Series G”).

The Series G stock has a stated value of $1,000 per share, and is convertible into common stock at a conversion price equal to 85% of the lowest sale price of the common stock on its listed market over the five trading days preceding the date of conversion ("Beneficial Conversion Feature"), subject to a maximum conversion price. The number of shares of common stock that may be converted is determined by dividing the stated value of the number of shares of Series G to be converted by the conversion price. The Company may elect to pay the Series G holder in cash at the current market price multiplied by the number of shares of common stock issuable upon conversion.

For the period ended September 30, 2013 and the year ended December 31, 2012, no shares of Series G were converted into shares of common stock. At September 30, 2013 and December 31, 2012, the outstanding Series G shares were convertible into a minimum of 1,415,933 and 991,153 shares of common stock, respectively.

Upon a change in control, sale of or similar transaction, as defined in the Certificate of Designation for the Series G, each holder of the Series G has the option to deem such transaction as a liquidation and may redeem his or her shares at the liquidation value of $1,000, per share, for an aggregate amount of $168,496.  The sale of all the assets on June 28, 2007 triggered the preferred stockholders’ redemption option.  As such redemption is not in the control of the Company, the Series G stock has been accounted for as if it was redeemable preferred stock and is classified on the balance sheet between liabilities and stockholders’ equity.

The conversion feature of the preferred stock is considered a derivative according to ASC 815 “Derivatives and Hedging”, therefore, the fair value of the derivative is reflected in the financial statements as a liability, which was determined to be $71,884 as of September 30, 2013, and has been included as “conversion feature liability” on the accompanying balance sheets. As of December 31, 2012, the fair value of the derivative was determined to be $108,839.

12

The fair value of the conversion feature liability is calculated under a Black-Scholes Model, using the market price of the Company’s common stock on each of the balance sheet dates presented, the expected dividend yield, the expected life of the redemption and the expected volatility of the Company’s common stock.

The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and considering factors specific to the conversion feature liability. Since some of the assumptions used by the Company are unobservable, the conversion feature liability is classified within level 3 hierarchy in the fair value measurement.

The expected volatility of the conversion feature liability was based on the historical volatility of the Company’s common stock. The expected life assumption was based on the remaining life of the underlying preferred stock redemption. The risk-free interest rate for the expected term of the conversion feature liability was based on the average market rate on U.S. treasury securities in effect during the applicable quarter. The dividend yield reflected historical experience as well as future expectations over the expected term of the underlying preferred stock redemption. Therefore, the fair value of the conversion feature liability is sensitive to changes in above assumptions and changes of the Company’s common stock price.

The table below shows the quantitative information about the significant unobservable inputs used in the fair value measurement of level 3 conversion feature liability:

Expected life of the redemption in years	1.0
Risk free interest rate	0.10	%
Expected annual volatility	78.24	%
Annual rate of dividends	0	%

The changes in the fair value of the derivative are as follows:

Balance as of January 1, 2013	$	108,839
Decrease of fair value		(36,955)
Ending balance as of September 30, 2013	$	71,884

7.  Stock-based Compensation

On August 15, 2008, the Company granted 25,000 non-qualified stock options to each of its four directors.  These options had a vesting period of one year from the date of grant, and they became fully vested and exercisable on August 15, 2009.  These options expired on August 15, 2013.  As of December 31, 2012, 100,000 options remained outstanding under this grant, and as of September 30, 2013 no options remain outstanding under this grant.

FASB ASC 718 “Compensation-Stock Compensation” requires entities to estimate the number of forfeitures expected to occur and record expense based upon the number of awards expected to vest.  The outstanding stock options under the 1998 Plan have been fully vested and related expenses were fully amortized for the nine months and three months ended September 30, 2013.

13

For the nine months and three months ended September 30, 2013, option activity was as follows:

	Shares	Weighted- Average Exercise Price		Remaining Contractual Term
Outstanding at beginning of period	100,000	$	0.38		0.13
Granted	-		-
Expired and forfeited	(100,000)		0.38
Exercised	-		-
Outstanding at end of period	-	$	-		-
Exercisable at September 30, 2013	-	$	-		-

The Company has outstanding 30,000 warrants issued in lieu of consulting fees, which expire in July 2014 and have an exercise price of $0.63 per share.

The Company agreed to compensate two of its four directors by issuing common stock and one director in cash for services rendered in 2013 and 2012. Two of these directors are affiliated with the advisory services firm that is currently providing investment banking services to the Company.  The Company agreed to compensate the fourth director in a combination of cash and common stock for services rendered in the first quarter 2013 and 2012.  Beginning in the second quarter of 2013 and continuing through 2013, the Company agreed to compensate this director in cash instead of cash and common stock.  The number of shares issued to each director was determined based upon the equivalent cash compensation accrued divided by the closing price of the Company’s common stock on the date that the compensation is fully earned each quarter, which is the last day of such quarter. The Company recorded stock-based compensation as common of $12,500 for the quarter ending September 30, 2013 for two directors, which is recorded as common stock to be issued.

On January 17, 2013, the Company issued 31,250 shares of common stock to each of two directors, and 15,626 shares of common stock to another director, as compensation for the three months ended December 31, 2012. These shares, totaling 78,126, were valued at a per share price of $0.20, or a total of $15,625.

On April 12, 2013, the Company issued 34,722 shares of common stock to each of two directors, and 17,362 shares of common stock to another director, as compensation for the three months ended March 31, 2013. These shares, totaling 86,806, were valued at a per share price of $0.18, or a total of $15,625.

On July 15, 2013, the Company issued 39,063 shares of common stock to each of two directors as compensation for the three months ended June 30, 2013. These shares, totaling 78,126, were valued at a per share price of $0.16, or a total of $12,500.

On October 11, 2013, the Company issued 44,643 shares of common stock to each of two directors as compensation for the three months ended September 30, 2013. These shares, totaling 89,286, were valued at a per share price of $0.14, or a total of $12,500.

8.   Income Taxes

The Company accounts for income taxes under FASB ASC 740 “Accounting for Income Taxes.”  Deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards, and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities in the Company’s financial statements and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that all or some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

The Company is no longer subject to U.S. federal and state income tax examination by tax authorities for years before 2008.

The Company has evaluated and concluded that there are no uncertain tax positions requiring recognition in the Company’s financial statements for nine months and three months ended September 30, 2013 and 2012.  The provision for income tax expense for the nine months ended September 30, 2013 was $800, and for the nine months ended September 30, 2012 was $8,013. The provision for income tax expense for the nine months ended September 30, 2012 includes a provision for alternative minimum tax.

14

As of September 30, 2013, and December 31, 2012, the Company had deferred tax assets primarily consisting of its net operating loss carryforwards.  However, because of the cumulative losses in several consecutive years, the Company has recorded a full valuation allowance such that its net deferred tax asset is zero.

The Company must make judgments as to whether the deferred tax assets will be recovered from future taxable income. To the extent that the Company believes that recovery is not likely, it must establish a valuation allowance.  A valuation allowance has been established for deferred tax assets which the Company does not believe meet the “more likely than not” criteria.  The Company’s judgments regarding future taxable income may change due to changes in market conditions, changes in tax laws, tax planning strategies or other factors.  If the Company’s assumptions and consequently its estimates change in the future, the valuation allowances it has  established may be increased or decreased, resulting in a respective increase or decrease in income tax expense.

9.   Related Party Transactions

The Company entered into an Investment Banking Advisory Services agreement in November 2007 with MDB Capital Group, LLC (“MDB”), and the parties extended this agreement indefinitely in April 2009.  The agreement may be terminated by either party upon 30-days written notice. The Company has not paid, nor is it currently obligated to pay, any fees to MDB pursuant to this agreement and no services have been provided by MDB.

The Company has a securities investment account with MDB, consisting of (a) available-for-sale investments totaling $2,581,268, that include short-term federal securities of $90,568, certificates of deposit, municipal securities and corporate bonds totaling $2,490,700 at September 30, 2013, and (b) available-for-sale investments totaling $2,658,190, that included short-term federal securities of $19,788, certificates of deposit, municipal securities and corporate bonds totaling $2,621,012, and equity securities of $17,390 at December 31, 2012.

Mr. Christopher Marlett, the Chief Executive Officer and director of the Company, is also the Chief Executive Officer of MDB. Mr. Gary Schuman, who is the Chief Financial Officer of the Company, is also the Chief Financial Officer and Chief Compliance Officer of MDB.  The Company reimburses MDB for Mr. Schuman’s services in the amount of $3,000 per month, totaling $27,000 for the nine months and $9,000 for each of the three months ended September 30, 2013 and 2012.  Mr. Robert Levande, who is an officer and director of the Company, is also a senior managing director of MDB.

10. Commitments and Contingencies

From time to time, the Company may be subject to other claims and litigation arising in the ordinary course of business.  The Company is not currently a party to any legal proceedings that it believes would reasonably be expected to have a material adverse effect on the Company’s business, financial condition or results of operations.

15

The following discussion should be read in conjunction with the unaudited financial statements and notes thereto in Part I, Item 1 of this Quarterly Report on Form 10-Q and with the audited financial statements and Notes thereto, and Management’s Discussion and Analysis of Financial Condition and Results of Operations that are included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012 as filed with the SEC.

Overview

The Company was incorporated in Delaware in 1990 and was founded to design, manufacture, sell and service image-directed, computer-controlled robotic software and hardware products for use in orthopedic surgical procedures. On June 28, 2007, the Company completed the sale of substantially all of its operating assets.  After completion of the sale, the Company no longer engaged in any business activities related to its former business described above. The Company has managed its financial assets to preserve capital on a conservative basis and not for investment return, so as not to be considered an investment company under the Investment Company Act of 1940. The Company’s current operations are limited to raising additional funds to be used to maintain the Company’s public company status and to complete a business combination or strategic alliance, if suitable candidate(s) are identified. To that end, since 2007, the Company has reviewed a number of business combination opportunities; however, none of these opportunities fit within the Company criteria or moved beyond preliminary review stages. The Company continues to evaluate business combination opportunities, and recently, it has considered several transactions that have come to the attention of the board of directors through its members.

On April 20, 2011, the Company purchased 363,636 shares of common stock of ClearSign Combustion Corporation, a privately-held Washington corporation (“ClearSign”), for an aggregate purchase price of $1,000,000, or $2.75 per share, in connection with ClearSign’s private offering of up to $3,000,000 of its common stock (the “ClearSign Offering”). Due to a 1.25-for-one stock split, which occurred subsequent to this purchase, the Company held 454,545 shares of common stock of ClearSign.  ClearSign is an early-stage clean energy company focused on developing technology to increase energy efficiency in most types of industrial combustion systems. ClearSign filed a registration statement on Form S-1 (as amended) for the initial public offering of its common stock that was declared effective April 24, 2012. On April 25, 2012, ClearSign Combustion Corporation (“ClearSign”) completed an initial public offering selling 3,000,000 shares of its common stock at $4.00 per share, and trading under symbol CLIR on the NASDAQ. The shares of common stock of ClearSign previously acquired in a private placement by the Company were registered as part of the offering.

On April 24, 2012, the Company’s board of directors declared a dividend to the stockholders of the Company, of an aggregate of 450,000 shares of common stock of ClearSign. The dividend was at the rate of 0.05513475 shares of ClearSign for each share of common stock of the Company, which equates to one share of common stock of ClearSign for approximately 18.137 shares of the Company’s common stock. The record date of the dividend was May 9, 2012, and the payment date of the dividend was May 23, 2012. As of September 30, 2013, the Company has sold its remaining shares of ClearSign.

As of September 30, 2013, the Company had no employees, and the Company relies on outside contractors to perform basic and necessary services.

Results of Operations

Nine months Ended September 30, 2013 and 2012

For the nine months ended September 30, 2013 and 2012, the Company had a net loss of $124,033 and net income of $615,373, respectively. The decrease in net income was due primarily to the recording of a gain on the Company’s investment in ClearSign of approximately $811,700 in the nine months ending September 30, 2012, offset by the change in fair value of the conversion feature liability, and an increase in realized gain from investment in-available-for-sale securities in the current period. General and administrative expenses were $202,220 and $203,189 for the nine months ended September 30, 2013 and 2012, respectively. Legal fees increased by approximately $9,000 for the nine months ended September 30, 2013 compared to the nine months ended September 30, 2012 due primarily to attorney services required for an SEC inquiry. Accounting fees decreased from approximately $76,000 in the nine months ended September 30, 2012 to approximately $69,000 in the nine months ended September 30, 2013 due to non-recurring costs associated with changing financial auditors in the nine months ended September 30, 2012. Outside services expense decreased from approximately $18,000 in the nine months ended September 30, 2012 to approximately $12,000 in the nine months ended September 30, 2013 due to expenses associated with the distribution of the Company’s investment in ClearSign in the nine months ending September 30, 2012. The Company had a realized loss in available-for-sale securities for the nine months ended September 30, 2013 and 2012 of approximately $3,400 and $1,200, respectively. Change in fair value of conversion feature was a decrease of approximately $37,000 for the nine months ended September 30, 2013, due to the change in fair value of the conversion feature of the Company’s convertible preferred stock; the change in value was an increase of approximately $33,000 for the same period in 2012.

Three months Ended September 30, 2013 and 2012

For the three months ended September 30, 2013 and 2012, the Company had a net loss of $57,363 and $34,873, respectively. The decrease in net income was due primarily to the decrease in interest income in the three months ending September 30, 2012. General and administrative expenses were $54,825 and $54,934 for the three months ended September 30, 2013 and 2012, respectively. Legal fees decreased by approximately $2,100 for the three months ended September 30, 2013 compared to the three months ended September 30, 2012. Outside services expense increased from approximately $2,600 in the three months ended September 30, 2012 to approximately $4,800 in the three months ended September 30, 2013 due to increased transfer agent fees in the current period. Net interest income was approximately $12,200 and $19,800 for the three months ended September 30, 2013 and 2012, respectively. The Company had a realized loss in available-for-sale securities of approximately $15,000 and $100 for the three months ended September 30, 2013 and September 30, 2012, respectively. Change in fair value of conversion feature was a decrease of approximately $245 for the three months ended September 30, 2013, due to the change in fair value of the conversion feature of the Company’s convertible preferred stock; the change in value was an increase of approximately $300 for the same period in 2012.

Liquidity and Capital Resources

The Company believes that existing cash, cash equivalents, and short-term available-for-sale securities will provide sufficient working capital for the Company to meet its operating plan for the next twelve months. The Board of Directors, including a director as its Chief Executive Officer, another director as its Secretary, and the Chief Financial Officer of a related party as the Company’s Chief Financial Officer assist the Company with its continuing obligations under the federal securities laws and to assist with the Company’s plan to evaluate various merger, acquisition, or strategic alliance opportunities. None of these individuals receive additional compensation, other than that which is disclosed herein, for providing this assistance. The Company does not have an estimate as to when it will identify a qualified merger, acquisition, or strategic alliance candidate.  There is no assurance that such opportunities will be available, or if available, upon favorable terms.  If the Company is unsuccessful in completing a suitable merger, acquisition or strategic alliance, then the Board of Directors may liquidate the Company and distribute all its remaining assets, which consist primarily of cash and available-for-sale securities, to its stockholders.

The Company anticipates that it will incur operating losses from operations in the next twelve months, until it enters into a suitable merger, acquisition or strategic alliance transaction, or until its liquidation.

Cash used in operating activities for the nine months ending September 30, 2013 was approximately $111,400, which primarily consisted of operating loss of approximately $124,000 and an increase in accounts payable of $11,000, and a decrease in other current assets of approximately $4,800, and adjustments for non-cash expenses consisting of stock-based compensation of approximately $41,000 and offset by a change in the conversion feature liability of $37,000 related to the Company’s Series G Convertible Preferred Stock and realized loss of approximately $3,400 on available for sale securities.

17

Cash provided by investing activities for the nine months ending September 30, 2013 of approximately $69,000 was from the maturity or sale of available-for-sale securities of approximately $1,547,000, offset by the purchase of available-for-sale securities of approximately $1,478,000.

Cash used in operating activities for the nine months ending September 30, 2012 was approximately $105,000, which primarily consisted of operating income of approximately $615,000 and an increase in accounts payable of $8,500, and adjustments for non-cash expenses consisting of stock-based compensation of $47,000 and conversion feature liability of $33,000 related to the Company’s Series G Convertible Preferred Stock, offset by an adjustment for a non-cash gain in investment in ClearSign of approximately $812,000.

Cash provided by investing activities for the nine months ending September 30, 2012 of approximately $485,000 was from the purchase of available-for-sale securities of approximately $1,492,000, offset by the maturity or sale of available-for-sale securities of approximately $1,977,000.

Critical Accounting Policies and Estimates

The Company’s discussion and analysis of the financial condition and results of operations are based upon the Company’s unaudited financial statements included elsewhere in this Form 10-Q and has been prepared in accordance with accounting principles generally accepted in the United States of America as disclosed in the Company’s annual financial statements in its Form 10-K for the year ended December 31, 2012.  Interim results are not necessarily indicative of the results for a full year.

The Company has discussed its critical accounting policies with the Board of Directors.

Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the reporting period.  Actual results could differ from those estimates.

Investments in Available-for-Sale Securities

The Company has a portfolio of investments in available-for-sale debt securities, which consist of fixed income debt securities, which are accounted for in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 320, “Investments - Debt and Equity Securities.”  Management determines the appropriate classification of the securities at the time they are acquired and evaluates the appropriateness of such classifications at each balance sheet date.  Available-for-sale securities are stated at fair value, and unrealized holding gains and losses, net of the related deferred tax effect, if any, are reported as other comprehensive income, a separate component of stockholders’ equity.

Financial Instruments

The Company considers the carrying amounts of financial instruments, including cash, other current assets and accounts payable to approximate their fair values because of the short term nature of those instruments.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Market risk represents the risk of loss that may impact the Company’s financial position, operating results or cash flows due to changes in U.S. interest rates.  The Company’s exposure to market risk is confined to its available-for-sale investments that it expects to hold less than one year. The goals of the Company’s cash investment policy are the security of the principal amount invested and fulfillment of liquidity needs.  The Company currently does not hedge interest rate exposure. Because of the short-term nature of its investments, the Company does not believe that an increase in market rates would have any material negative impact on the value of its investment portfolio.

18

As of September 30, 2013, the Company held approximately $72,000 in money market and checking accounts at two institutions.  The Company has a checking account at one institution with a balance of approximately $22,000 at September 30, 2013.  The funds in this account are fully insured by the Federal Deposit Insurance Corporation (“FDIC”) as of September 30, 2013.   The Company has a money market account in a brokerage account with a second financial institution, invested in short-term federal securities and corporate bonds, with a money market cash balance of approximately $50,000 at September 30, 2013. Assets in this brokerage account are protected by the Securities Investor Protection Corporation (“SIPC”) up to $500,000.  The Company had no uninsured cash and cash equivalents at September 30, 2013.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time period specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the reports filed under the Exchange Act is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer. We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of September 30, 2013 (the “Evaluation Date”). Based upon the evaluation of our disclosure controls and procedures as of the Evaluation Date, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective because of the identification of a material weakness in our internal control over financial reporting which is identified below, which we view as an integral part of our disclosure controls and procedures.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Rule 13a-15(f). Our internal control over financial reporting is a process designed to provide reasonable assurance to our management and board of directors regarding the reliability of financial reporting and the preparation of the financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.

Our internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America, and our receipts and expenditures of are being made only in accordance with authorizations of our management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal controls over financial reporting may not prevent or detect misstatements. All internal control systems, no matter how well designed, have inherent limitations, including the possibility of human error and the circumvention of overriding controls. Accordingly, even effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2012. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework. Based on its evaluation, our management concluded that there is a material weakness in our internal control over financial reporting and management has concluded that the Company’s internal controls over financial reporting are ineffective as of December 31, 2012. A material weakness is a deficiency, or a combination of control deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. Management believes that despite these weaknesses in internal controls, there are no material misstatements in our annual financial statements.

19

The material weakness relates to the lack of segregation of duties in our financial reporting process and our utilization of outside third party consultants. We do not have a seperately designated audit committee. These weaknesses are due to our lack of additional accounting and operational staff. To remedy this material weakness, we ultimately, if and when we conclude a business combination, will engage an internal accounting staff to assist with financial reporting.

Changes in Internal Controls over Financial Reporting

There were no changes in our internal control over financial reporting during quarter ended September 30, 2013, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the Effectiveness of Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management or board override of the control.

The design of any system of controls also is based in part upon 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; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Part II. OTHER INFORMATION

Item 1.  Legal Proceedings

From time to time, the Company may be subject to claims and litigation arising in the ordinary course of business.  The Company is not currently a party to any legal proceedings that it believes would reasonably be expected to have a material adverse effect on the Company’s business, financial condition or results of operations.

Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2013

Accounting Policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

Basis of Presentation

The accompanying unaudited financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial statements and with the rules and regulations under Regulation S-X of the Securities and Exchange Commission for Form 10-Q. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statement presentation. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary to present fairly the financial position as of September 30, 2013, the results of operations and cash flows for the nine months then ended have been included. These financial statements should be read in conjunction with the financial statements of the Company and the Company’s management discussion and analysis included in the Company’s Form 10-K for the year ended December 31, 2012. Interim results are not necessarily indicative of the results for a full year.

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 of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses for the reporting period.  Actual results could differ from those estimates.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and cash equivalents

Cash and cash equivalents include checking and money market accounts held in two financial institutions. The Company has a checking account at one institution with a balance of approximately $22,000 at September 30, 2013. The funds in this account are fully guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. The Company has a money market account in a brokerage account with a second financial institution, with a money market cash balance of approximately $50,000 at September 30, 2013. Assets in this brokerage account are protected by the Securities Investor Protection Corporation (“SIPC”) up to $500,000.  The Company had no uninsured cash and cash equivalents at September 30, 2013.

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

Stock-Based Compensation

Compensation costs for stock, warrants or options issued to employees and non-employees are based on the fair value method and accounted for in accordance with FASB ASC 718, “ Compensation – Stock Compensation .”  The value of warrants and options are calculated using a Black-Scholes Model, using the market price of the Company’s common stock on the date of issuance for the employee options and the date of commitment for non-employee options, an expected dividend yield of zero, the expected life of the warrants or options and the expected volatility of the Company’s common stock.

Marketable Securities, Available-for-sale Securities, Policy [Policy Text Block]

Investment in Available-for-Sale Securities

The Company has a portfolio of investments in available-for-sale debt securities, which consist of fixed income debt securities and equity securities, which are accounted for in accordance with FASB ASC 320, “Investments - Debt and Equity Securities.”  Management determines the appropriate classification of the securities at the time they are acquired and evaluates the appropriateness of such classifications at each balance sheet date.  Available-for-sale securities are stated at fair value, and unrealized holding gains and losses, net of the related deferred tax effect, if any, are reported as other comprehensive income, a separate component of stockholders’ equity.

Fair Value Measurement, Policy [Policy Text Block]

Fair Value Measurement

FASB ASC 820“Fair Value Measurements and Disclosures” clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, FASB ASC 820 establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

⋅ Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

⋅ Level 2 - Include other inputs that are directly or indirectly observable in the marketplace.

⋅ Level 3 - Unobservable inputs which are supported by little or no market activity.

The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

In accordance with FASB ASC 820, the Company measures its cash equivalents, investments in available-for-sale securities, and derivative liability at fair value. The Company’s cash equivalents and investments in available-for-sale securities are classified within Level 1 by using quoted market prices. The Company’s derivative liability is classified within Level 3.

The carrying value of other current assets and liabilities are considered to be representative of their respective fair values because of the short-term nature of those instruments.

Income Tax, Policy [Policy Text Block]

Income Taxes

Deferred income taxes have been provided for temporary differences between financial statement and income tax reporting under the liability method, using expected tax rates and laws that are expected to be in effect when the differences are expected to reverse.  A valuation allowance is provided when realization is not considered more likely than not.

The Company applies the provisions of FASB ASC 740, “Income Taxes.”  ASC 740 clarifies the accounting for uncertainty in income taxes recognized in the Company’s financial statements in accordance with ASC 740, “Income Taxes,” and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

The Company’s policy is to classify expenses as a result of income tax assessments as interest expense for interest charges and as penalties in general and administrative expenses for penalty assessments.

Cost Basis Method Valuation [Policy Text Block]

Cost-Basis Method Valuation

The Company’s non-marketable equity investment was previously recorded using the cost-basis method of accounting, and was classified as a long-term asset on the accompanying balance sheet as permitted by FASB ASC 325, “Cost Method Investments”, as the Company owned less than 20% of the voting securities and did not have the ability to exercise significant influence over operating and financial policies of the entity. In 2012, the Company distributed a majority of this investment to its stockholders and reclassified the remaining shares as available-for-sale securities. During the same period, the investee’s stock became publicly traded and its fair value became readily available. Therefore, these shares have been accounted for in accordance with FASB ASC 320, “Investment – Debt and Equity Securities”.   See Note 5, “Investment in ClearSign” for more information. The remaining shares were sold during the three months ended June 30, 2013.

Recently Announced Accounting Pronouncements, Policy [Policy Text Block]

Recently Adopted Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2011-04, “Fair Value Measurement” (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs. This guidance amends the disclosure requirements related to recurring and nonrecurring fair value measurements and includes the following provisions:  application of the concepts of highest and best use and valuation premise, introduction of an option to measure groups of offsetting assets and liabilities on a net basis, incorporation of certain premiums and discounts in fair value measurements, and the measurement of fair value of certain instruments classified in shareholders’ equity. In addition, the amended guidance includes several new fair value disclosure requirements, including, among other things, information about valuation techniques and unobservable inputs used in Level 3 fair value measurements and a narrative description of Level 3 measurements’ sensitivity to changes in unobservable inputs. The guidance became effective for the reporting period beginning January 1, 2012. The adoption of this guidance did not have a material impact on the Company’s financial statements.

In June 2011, the FASB issued Accounting Standards Update 2011-05, “Comprehensive Income” (Topic 220): Presentation of Comprehensive Income. This amended guidance eliminates the option for reporting entities to present components of other comprehensive income in the statement of stockholders’ equity. Instead, this amended guidance now requires reporting entities to present all non-owner changes in stockholders’ equity either as a single continuous statement of comprehensive income or as two separate but consecutive statements. The guidance became effective for the reporting period beginning January 1, 2012. The adoption of this guidance did not have a material impact on the Company’s financial statements.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Announced Accounting Pronouncements

In July 2013, the FASB issued Accounting Standards Update 2013-11, “Income Taxes” (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This amended guidance will require an unrecognized tax benefit, or a portion of an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The guidance will become effective for the reporting period beginning January 1, 2014. The adoption of this guidance is not estimated to have a material impact on the Company’s financial statements.

Management does not believe that any other recently issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying financial statements.

Accounting Policies [Abstract]

Basis of Presentation and Significant Accounting Policies [Text Block]

2. Significant Accounting Policies

Basis of Presentation

The accompanying unaudited financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial statements and with the rules and regulations under Regulation S-X of the Securities and Exchange Commission for Form 10-Q. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statement presentation. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary to present fairly the financial position as of September 30, 2013, the results of operations and cash flows for the nine months then ended have been included. These financial statements should be read in conjunction with the financial statements of the Company and the Company’s management discussion and analysis included in the Company’s Form 10-K for the year ended December 31, 2012. Interim results are not necessarily indicative of the results for a full year.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses for the reporting period.  Actual results could differ from those estimates.

Cash and cash equivalents

Cash and cash equivalents include checking and money market accounts held in two financial institutions. The Company has a checking account at one institution with a balance of approximately $22,000 at September 30, 2013. The funds in this account are fully guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. The Company has a money market account in a brokerage account with a second financial institution, with a money market cash balance of approximately $50,000 at September 30, 2013. Assets in this brokerage account are protected by the Securities Investor Protection Corporation (“SIPC”) up to $500,000.  The Company had no uninsured cash and cash equivalents at September 30, 2013.

Stock-Based Compensation

Compensation costs for stock, warrants or options issued to employees and non-employees are based on the fair value method and accounted for in accordance with FASB ASC 718, “ Compensation – Stock Compensation .”  The value of warrants and options are calculated using a Black-Scholes Model, using the market price of the Company’s common stock on the date of issuance for the employee options and the date of commitment for non-employee options, an expected dividend yield of zero, the expected life of the warrants or options and the expected volatility of the Company’s common stock.

Investment in Available-for-Sale Securities

The Company has a portfolio of investments in available-for-sale debt securities, which consist of fixed income debt securities and equity securities, which are accounted for in accordance with FASB ASC 320, “Investments - Debt and Equity Securities.”  Management determines the appropriate classification of the securities at the time they are acquired and evaluates the appropriateness of such classifications at each balance sheet date.  Available-for-sale securities are stated at fair value, and unrealized holding gains and losses, net of the related deferred tax effect, if any, are reported as other comprehensive income, a separate component of stockholders’ equity.

Fair Value Measurement

FASB ASC 820“Fair Value Measurements and Disclosures” clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, FASB ASC 820 establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

⋅ Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

⋅ Level 2 - Include other inputs that are directly or indirectly observable in the marketplace.

⋅ Level 3 - Unobservable inputs which are supported by little or no market activity.

The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

In accordance with FASB ASC 820, the Company measures its cash equivalents, investments in available-for-sale securities, and derivative liability at fair value. The Company’s cash equivalents and investments in available-for-sale securities are classified within Level 1 by using quoted market prices. The Company’s derivative liability is classified within Level 3.

The carrying value of other current assets and liabilities are considered to be representative of their respective fair values because of the short-term nature of those instruments.

Income Taxes

Deferred income taxes have been provided for temporary differences between financial statement and income tax reporting under the liability method, using expected tax rates and laws that are expected to be in effect when the differences are expected to reverse.  A valuation allowance is provided when realization is not considered more likely than not.

The Company applies the provisions of FASB ASC 740, “Income Taxes.”  ASC 740 clarifies the accounting for uncertainty in income taxes recognized in the Company’s financial statements in accordance with ASC 740, “Income Taxes,” and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

The Company’s policy is to classify expenses as a result of income tax assessments as interest expense for interest charges and as penalties in general and administrative expenses for penalty assessments.

Cost-Basis Method Valuation

The Company’s non-marketable equity investment was previously recorded using the cost-basis method of accounting, and was classified as a long-term asset on the accompanying balance sheet as permitted by FASB ASC 325, “Cost Method Investments”, as the Company owned less than 20% of the voting securities and did not have the ability to exercise significant influence over operating and financial policies of the entity. In 2012, the Company distributed a majority of this investment to its stockholders and reclassified the remaining shares as available-for-sale securities. During the same period, the investee’s stock became publicly traded and its fair value became readily available. Therefore, these shares have been accounted for in accordance with FASB ASC 320, “Investment – Debt and Equity Securities”.   See Note 5, “Investment in ClearSign” for more information. The remaining shares were sold during the three months ended June 30, 2013.

Recently Adopted Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2011-04, “Fair Value Measurement” (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs. This guidance amends the disclosure requirements related to recurring and nonrecurring fair value measurements and includes the following provisions:  application of the concepts of highest and best use and valuation premise, introduction of an option to measure groups of offsetting assets and liabilities on a net basis, incorporation of certain premiums and discounts in fair value measurements, and the measurement of fair value of certain instruments classified in shareholders’ equity. In addition, the amended guidance includes several new fair value disclosure requirements, including, among other things, information about valuation techniques and unobservable inputs used in Level 3 fair value measurements and a narrative description of Level 3 measurements’ sensitivity to changes in unobservable inputs. The guidance became effective for the reporting period beginning January 1, 2012. The adoption of this guidance did not have a material impact on the Company’s financial statements.

In June 2011, the FASB issued Accounting Standards Update 2011-05, “Comprehensive Income” (Topic 220): Presentation of Comprehensive Income. This amended guidance eliminates the option for reporting entities to present components of other comprehensive income in the statement of stockholders’ equity. Instead, this amended guidance now requires reporting entities to present all non-owner changes in stockholders’ equity either as a single continuous statement of comprehensive income or as two separate but consecutive statements. The guidance became effective for the reporting period beginning January 1, 2012. The adoption of this guidance did not have a material impact on the Company’s financial statements.

Recently Announced Accounting Pronouncements

In July 2013, the FASB issued Accounting Standards Update 2013-11, “Income Taxes” (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This amended guidance will require an unrecognized tax benefit, or a portion of an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The guidance will become effective for the reporting period beginning January 1, 2014. The adoption of this guidance is not estimated to have a material impact on the Company’s financial statements.

Management does not believe that any other recently issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying financial statements.

5.  Cost-Basis Investment

On April 20, 2011, the Company purchased 363,636 shares of common stock of ClearSign Combustion Corporation, a privately-held Washington corporation (“ClearSign”), for an aggregate purchase price of $1,000,000, or $2.75 per share, in connection with ClearSign’s private offering of up to $3,000,000 of its common stock (the “ClearSign Offering”). Due to a 1.25-for-one stock split, which occurred subsequent to this purchase, the Company held 454,545 shares of common stock of ClearSign. Prior to June 30, 2012, this investment had been accounted for using the cost method, as the Company owned less than 20% of the voting securities and did not have the ability to exercise significant influence over operating and financial policies of the entity. 

ClearSign filed a registration statement on Form S-1 (as amended) for the initial public offering of its common stock that was declared effective April 24, 2012. On April 25, 2012, ClearSign Combustion Corporation (“ClearSign”) completed an initial public offering selling 3,000,000 shares of its common stock at $4.00 per share, and trading under the symbol CLIR on NASDAQ.  The shares of common stock of ClearSign previously acquired in a private placement by the Company were registered for resale or distribution as part of the offering.

On April 24, 2012, the Company’s board of directors declared a dividend to the shareholders of the Company, of an aggregate of 450,000 shares of common stock of ClearSign. The dividend was at the rate of 0.05513475 shares of ClearSign for each share of common stock of the Company, which equates to one share of common stock of ClearSign for approximately 18.137 shares of the Company’s common stock. The record date of the dividend was May 9, 2012, and the payment date of the dividend was May 23, 2012. A total of 450,952 shares of ClearSign were distributed, including 952 rounding shares. In 2012, the Company recorded a gain of $811,713 equal to the increase in the fair value of the ClearSign investment which had been distributed, or $1,803,808, as measured on April 25, 2012 less the cost basis of the investment.

The Company retained 3,593 shares of ClearSign common stock, which were then sold on April 29, 2013. A realized gain of $24,475 was recorded during the nine months ended September 30, 2013.

Earnings Per Share [Text Block]

3.  Income (Loss) Per Share

Basic income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period plus dilutive common stock equivalents, using the treasury stock method.

Common stock equivalents for convertible preferred stock of 1,158,845 and 1,217,457 shares were excluded from the calculation of loss per share for the nine months ended September 30, 2013 and the three months ended September 30, 2013, respectively, because they were not dilutive; these shares would have been dilutive if the Company had not had a net loss for the this period.  Common stock equivalents for convertible preferred stock of 991,153 shares were included in calculation of gain per share for the nine months and three months ended September 30, 2012.

A warrant for 30,000 shares was excluded from the calculation of loss per share for the nine months and three months ended September 30, 2013, and a warrant for 30,000 shares, and stock options of 100,000 were excluded from the calculation of income (loss) per share for the nine months and three months ended September 30, 2012, respectively, because their effect was anti-dilutive.

Income Tax Disclosure [Abstract]

Income Tax Disclosure [Text Block]

8.   Income Taxes

The Company accounts for income taxes under FASB ASC 740 “Accounting for Income Taxes.”  Deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards, and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities in the Company’s financial statements and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that all or some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

The Company is no longer subject to U.S. federal and state income tax examination by tax authorities for years before 2008.

The Company has evaluated and concluded that there are no uncertain tax positions requiring recognition in the Company’s financial statements for nine months and three months ended September 30, 2013 and 2012.  The provision for income tax expense for the nine months ended September 30, 2013 was $800, and for the nine months ended September 30, 2012 was $8,013. The provision for income tax expense for the nine months ended September 30, 2012 includes a provision for alternative minimum tax.

As of September 30, 2013, and December 31, 2012, the Company had deferred tax assets primarily consisting of its net operating loss carryforwards.  However, because of the cumulative losses in several consecutive years, the Company has recorded a full valuation allowance such that its net deferred tax asset is zero.

The Company must make judgments as to whether the deferred tax assets will be recovered from future taxable income. To the extent that the Company believes that recovery is not likely, it must establish a valuation allowance.  A valuation allowance has been established for deferred tax assets which the Company does not believe meet the “more likely than not” criteria.  The Company’s judgments regarding future taxable income may change due to changes in market conditions, changes in tax laws, tax planning strategies or other factors.  If the Company’s assumptions and consequently its estimates change in the future, the valuation allowances it has  established may be increased or decreased, resulting in a respective increase or decrease in income tax expense.

7.  Stock-based Compensation

On August 15, 2008, the Company granted 25,000 non-qualified stock options to each of its four directors.  These options had a vesting period of one year from the date of grant, and they became fully vested and exercisable on August 15, 2009.  These options expired on August 15, 2013.  As of December 31, 2012, 100,000 options remained outstanding under this grant, and as of September 30, 2013 no options remain outstanding under this grant.

FASB ASC 718 “Compensation-Stock Compensation” requires entities to estimate the number of forfeitures expected to occur and record expense based upon the number of awards expected to vest.   The outstanding stock options under the 1998 Plan have been fully vested and related expenses were fully amortized for the nine months and three months ended September 30, 2013.

For the nine months and three months ended September 30, 2013, option activity was as follows:

	Shares	Weighted- Average Exercise Price		Remaining Contractual Term
Outstanding at beginning of period	100,000	$	0.38		0.13
Granted	-		-
Expired and forfeited	(100,000)		0.38
Exercised	-		-
Outstanding at end of period	-	$	-		-
Exercisable at September 30, 2013	-	$	-		-

The Company has outstanding 30,000 warrants issued in lieu of consulting fees, which expire in July 2014 and have an exercise price of $0.63 per share.

The Company agreed to compensate two of its four directors by issuing common stock and one director in cash for services rendered in 2013 and 2012.  Two of these directors are affiliated with the advisory services firm that is currently providing investment banking services to the Company.  The Company agreed to compensate the fourth director in a combination of cash and common stock for services rendered in the first quarter 2013 and 2012.   Beginning in the second quarter of 2013 and continuing through 2013, the Company agreed to compensate this director in cash instead of cash and common stock.  The number of shares issued to each director was determined based upon the equivalent cash compensation accrued divided by the closing price of the Company’s common stock on the date that the compensation is fully earned each quarter, which is the last day of such quarter. The Company recorded stock-based compensation as common of $12,500 for the quarter ending September 30, 2013 for two directors, which is recorded as common stock to be issued.

On January 17, 2013, the Company issued 31,250 shares of common stock to each of two directors, and 15,626 shares of common stock to another director, as compensation for the three months ended December 31, 2012. These shares, totaling 78,126, were valued at a per share price of $0.20, or a total of $15,625.

On April 12, 2013, the Company issued 34,722 shares of common stock to each of two directors, and 17,362 shares of common stock to another director, as compensation for the three months ended March 31, 2013. These shares, totaling 86,806, were valued at a per share price of $0.18, or a total of $15,625.

On July 15, 2013, the Company issued 39,063 shares of common stock to each of two directors as compensation for the three months ended June 30, 2013. These shares, totaling 78,126, were valued at a per share price of $0.16, or a total of $12,500.

On October 11, 2013, the Company issued 44,643 shares of common stock to each of two directors as compensation for the three months ended September 30, 2013. These shares, totaling 89,286, were valued at a per share price of $0.14, or a total of $12,500.

Redeemable Convertible Preferred Stock

6.  Redeemable Convertible Preferred Stock

The Company’s Certificate of Incorporation authorized 1,000,000 shares of undesignated, serial preferred stock. Preferred stock may be issued from time to time in one or more series. The Board of Directors is authorized to determine the rights, preferences, privileges, and restrictions granted to and imposed upon any wholly unissued series of preferred stock and designation of any such series without any further vote or action by the Company’s stockholders.

As of September 30, 2013 and December 31, 2012, the Company’s only outstanding series of convertible preferred stock is the Series G Convertible Preferred Stock (“Series G”).

The Series G stock has a stated value of $1,000 per share, and is convertible into common stock at a conversion price equal to 85% of the lowest sale price of the common stock on its listed market over the five trading days preceding the date of conversion ("Beneficial Conversion Feature"), subject to a maximum conversion price. The number of shares of common stock that may be converted is determined by dividing the stated value of the number of shares of Series G to be converted by the conversion price. The Company may elect to pay the Series G holder in cash at the current market price multiplied by the number of shares of common stock issuable upon conversion.

For the period ended September 30, 2013 and the year ended December 31, 2012, no shares of Series G were converted into shares of common stock. At September 30, 2013 and December 31, 2012, the outstanding Series G shares were convertible into a minimum of 1,415,933 and 991,153 shares of common stock, respectively.

Upon a change in control, sale of or similar transaction, as defined in the Certificate of Designation for the Series G, each holder of the Series G has the option to deem such transaction as a liquidation and may redeem his or her shares at the liquidation value of $1,000, per share, for an aggregate amount of $168,496.  The sale of all the assets on June 28, 2007 triggered the preferred stockholders’ redemption option.  As such redemption is not in the control of the Company, the Series G stock has been accounted for as if it was redeemable preferred stock and is classified on the balance sheet between liabilities and stockholders’ equity.

The conversion feature of the preferred stock is considered a derivative according to ASC 815 “Derivatives and Hedging”, therefore, the fair value of the derivative is reflected in the financial statements as a liability, which was determined to be $71,884 as of September 30, 2013, and has been included as “conversion feature liability” on the accompanying balance sheets. As of December 31, 2012, the fair value of the derivative was determined to be $108,839.

The fair value of the conversion feature liability is calculated under a Black-Scholes Model, using the market price of the Company’s common stock on each of the balance sheet dates presented, the expected dividend yield, the expected life of the redemption and the expected volatility of the Company’s common stock.

The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and considering factors specific to the conversion feature liability. Since some of the assumptions used by the Company are unobservable, the conversion feature liability is classified within level 3 hierarchy in the fair value measurement.

The expected volatility of the conversion feature liability was based on the historical volatility of the Company’s common stock. The expected life assumption was based on the remaining life of the underlying preferred stock redemption. The risk-free interest rate for the expected term of the conversion feature liability was based on the average market rate on U.S. treasury securities in effect during the applicable quarter. The dividend yield reflected historical experience as well as future expectations over the expected term of the underlying preferred stock redemption. Therefore, the fair value of the conversion feature liability is sensitive to changes in above assumptions and changes of the Company’s common stock price.

The table below shows the quantitative information about the significant unobservable inputs used in the fair value measurement of level 3 conversion feature liability:

Expected life of the redemption in years	1.0
Risk free interest rate	0.10	%
Expected annual volatility	78.24	%
Annual rate of dividends	0	%

The changes in the fair value of the derivative are as follows:

Balance as of January 1, 2013	$	108,839
Decrease of fair value		(36,955)
Ending balance as of September 30, 2013	$	71,884
