| Note 1. | Basis of Presentation and Management’s Liquidity Plans | ||
| Basis of Presentation — The accompanying unaudited condensed consolidated interim financial statements include the accounts of Andrea Electronics Corporation and its subsidiaries (“Andrea” or the “Company”). All intercompany balances and transactions have been eliminated in consolidation. | |||
| These unaudited condensed consolidated interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In addition, the December 31, 2012 balance sheet data was derived from the audited consolidated financial statements, but does not include all disclosures required by GAAP. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The results of operations of any interim period are not necessarily indicative of the results of operations to be expected for any other interim period or for the fiscal year. | |||
| These unaudited condensed consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the fiscal year ended December 31, 2012 included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012, filed on March 29, 2013. The accounting policies used in preparing these unaudited condensed consolidated interim financial statements are consistent with those described in the December 31, 2012 audited consolidated financial statements. | |||

| Loss Per Share — Basic loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding during the period. Diluted loss adjusts basic loss per share for the effects of convertible securities, stock options and other potentially dilutive financial instruments, only in the periods in which such effect is dilutive. Diluted earnings per share are based on the assumption that all dilutive convertible shares and stock options were converted or exercised. Dilution is computed by applying the treasury stock method for the outstanding options, and the if-converted method for the outstanding convertible instruments. Under the treasury stock method, options are assumed to be exercised at the beginning of the period (or at the time of issuance, if later) and as if funds obtained thereby were used to purchase common stock at the average market price during the period. Under the if-converted method, outstanding convertible instruments are assumed to be converted into common stock at the beginning of the period (or at the time of issuance, if later). Securities that could potentially dilute basic earnings per share (“EPS”) in the future that were not included in the computation of the diluted EPS because to do so would have been anti-dilutive for the periods presented, consist of the following: | ||||||||||||||||||||||

At times during the periods ended September 30, 2013 and December 31, 2012, the Company had cash deposits in excess of the maximum amounts insured by the Federal Deposit Insurance Corporation insurance limits. At September 30, 2013 and December 31, 2012, the Company’s cash was held at two financial institutions. | ||||||||||||||||||||||

| Allowance for Doubtful Accounts — The Company performs on-going credit evaluations of its customers and adjusts credit limits based upon payment history and the customer’s current credit worthiness, as determined by the review of their current credit information. Collections and payments from customers are continuously monitored. The Company maintains an allowance for doubtful accounts, which is based upon historical experience as well as specific customer collection issues that have been identified. While such bad debt expenses have historically been within expectations and allowances established, the Company cannot guarantee that it will continue to experience the same credit loss rates that it has in the past. If the financial condition of customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. | ||||||||||||||||||||||
| Inventories — Inventories are stated at the lower of cost (on a first-in, first-out) or market basis. The cost of inventory is based on the respective cost of materials. Andrea reviews its inventory reserve for obsolescence on a quarterly basis and establishes reserves on inventories based on the specific identification method as well as a general reserve. Andrea records changes in inventory reserves as part of cost of revenues. | ||||||||||||||||||||||

| Intangible and Lived Assets — Andrea accounts for its long-lived assets in accordance with ASC 360 “Property, Plant and Equipment” for purposes of determining and measuring impairment of its long-lived assets (primarily intangible assets) other than goodwill. Andrea’s policy is to periodically review the value assigned to its long-lived assets to determine if they have been permanently impaired by adverse conditions which may affect Andrea. If Andrea identifies a permanent impairment such that the carrying amount of Andrea’s long lived assets are not recoverable using the sum of an undiscounted cash flow projection (gross margin dollars from product revenues), a new cost basis for the impaired asset will be established. If required, an impairment charge is recorded based on an estimate of future discounted cash flows. This new cost basis will be net of any recorded impairment. At September 30, 2013 and 2012, Andrea concluded that the Andrea DSP Microphone and Audio Software Products business segment was not required to be tested for recoverability. | ||||||||||||||||||||||
| Revenue Recognition — Non software-related revenue, which is generally comprised of microphones and microphone connectivity product revenues, is recognized when title and risk of loss pass to the customer, which is generally upon shipment. With respect to licensing revenues, Andrea recognizes revenue in accordance with ASC 985, “Software” and ASC 605 “Revenue Recognition.” License revenue is recognized based on the terms and conditions of individual contracts. In addition, fee based services, which are short-term in nature, are generally performed on a time-and-material basis under separate service arrangements and the corresponding revenue is generally recognized as the services are performed. | ||||||||||||||||||||||
| During the three months ended March 31, 2013, it was determined that certain royalties related to a customer’s licensing agreement were not reported for 2012 and for the quarter ended March 31, 2013. The amount of unreported royalty revenue due to the Company was determined during the three months ended June 30, 2013. Since the Company was unable to estimate this amount at March 31, 2013, the Company did not record any revenue related to the unreported royalty revenue. During the three months ended June 30, 2013, the Company reported revenue of approximately $445,000, of which $295,000 and $150,000 consisted of royalties related to the licensing agreement from 2012 and for the quarter ended March 31, 2013, respectively. | ||||||||||||||||||||||
| Income Taxes — Andrea accounts for income taxes in accordance with ASC 740, “Income Taxes” (“ASC 740”). ASC 740 requires an asset and liability approach for financial accounting and reporting for income taxes and establishes for all entities a minimum threshold for financial statement recognition of the benefit of tax positions, and requires certain expanded disclosures. The provision for income taxes is based upon income or loss after adjustment for those permanent items that are not considered in the | ||||||||||||||||||||||
| determination of taxable income. Deferred income taxes represent the tax effects of differences between the financial reporting and tax bases of the Company’s assets and liabilities at the enacted tax rates in effect for the years in which the differences are expected to reverse. The Company evaluates the recoverability of deferred tax assets and establishes a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Andrea expects it will reduce its valuation allowance in future periods to the extent that it can demonstrate its ability to utilize the assets. Management makes judgments as to the interpretation of the tax laws that might be challenged upon an audit and cause changes to previous estimates of tax liability. In management’s opinion, adequate provisions for income taxes have been made for all years. If actual taxable income by tax jurisdiction varies from estimates, additional allowances or reversals of reserves may be necessary. Income tax expense consists of the tax payable for the period and the change during the period in deferred tax assets and liabilities. The Company has identified its federal tax return and its state tax return in New York as “major” tax jurisdictions. Based on the Company’s evaluation, it has been concluded that there are no significant uncertain tax positions requiring recognition in the Company’s condensed consolidated interim financial statements. The Company’s evaluation was performed for tax years ended 2009 through 2012. The Company believes that its income tax positions and deductions will be sustained on audit and does not anticipate any adjustments that will result in a material change to its financial position. | ||||||||||||||||||||||
| The provision for income taxes for the three months ended September 30, 2013 of approximately $128,000 is a result of certain licensing revenues that are subject to withholding of income tax as mandated by the foreign jurisdiction in which the revenues are earned. Although this provision could be offset by future tax benefits since the Company records a full valuation against deferred tax assets, the provision of approximately $128,000 will not be reduced by such tax benefits. Additionally, approximately $87,000 of the provision recorded for the three months ended September 30, 2013 relates to royalty revenue reported during the three months ended June 30, 2013. At the time the revenue was reported, the Company was unaware that some portion of this revenue would be subject to foreign income tax as this income was previously exempt from foreign taxes. The provision for income taxes for the three months ended September 30, 2012 of approximately $155,000 is the result of increasing the valuation allowance against our deferred tax assets after considering changes in previously existing positive and negative evidence of the Company’s ability to utilize those deferred tax assets. | ||||||||||||||||||||||
| Stock-Based Compensation — At September 30, 2013, Andrea had two stock-based employee compensation plans, which are described more fully in Note 6. Andrea accounts for stock-based compensation in accordance with ASC 718, “Compensation — Stock Compensation” (“ASC 718”). ASC 718 establishes accounting for stock-based awards exchanged for employee services. Under the provisions of ASC 718, stock-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the employee’s requisite service period (generally the vesting period of the equity grant). The fair value of the Company’s common stock options are estimated using the Black Scholes option-pricing model with the following assumptions: expected volatility, dividend rate, risk free interest rate and the expected life. The Company expenses stock-based compensation by using the straight-line method. In accordance with ASC 718, excess tax benefits realized from the exercise of stock-based awards are classified in cash flows from financing activities. The future realization of the reserved deferred tax assets related to these tax benefits associated with the exercise of stock options will result in a credit to additional paid in capital if the related tax deduction reduces taxes payable. The Company has elected the “with and without approach” regarding ordering of windfall tax benefits to determine whether the windfall tax benefit did reduce taxes payable in the current year. Under this approach, the windfall tax benefit would be recognized in additional paid-in-capital only if an incremental tax benefit is realized after considering all other benefits presently available. | ||||||||||||||||||||||
| Use of Estimates — The preparation of condensed consolidated interim 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, liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated interim financial statements and the reported amounts of revenues and expenses during the reporting period. | ||||||||||||||||||||||
| Management bases its estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. The most significant estimates, among other things, are used in accounting for allowances for bad debts, inventory valuation and obsolescence, product warranty, depreciation, deferred income taxes, expected realizable values for assets (primarily intangible assets), contingencies, revenue recognition as well as the recording and presentation of the Company’s convertible preferred stock. Estimates and assumptions are periodically reviewed and the effects of any material revisions are reflected in the condensed consolidated interim financial statements in the period that they are determined to be necessary. Actual results could differ from those estimates and assumptions. | ||||||||||||||||||||||
| Subsequent Events — The Company evaluates events that occurred after the balance sheet date but before the condensed consolidated interim financial statements are issued. Based upon the evaluation, except as noted in Note 6, the Company did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the condensed consolidated interim financial statements | ||||||||||||||||||||||

| On October 10, 2000, Andrea issued and sold in a private placement $7,500,000 of Series C Redeemable Convertible Preferred Stock (the “Series C Preferred Stock”). Each of these shares of Series C Preferred Stock had a stated value of $10,000 plus a $1,671 increase in the stated value, which sum is convertible into Common Stock at a conversion price of $0.2551. On February 17, 2004, Andrea announced that it had entered into an Exchange and Termination Agreement and an Acknowledgment and Waiver Agreement, which eliminated the dividend of 5% per annum on the stated value. The additional amount of $1,671 represents the 5% per annum from October 10, 2000 through February 17, 2004. The shares of Series C Preferred Stock are subject to antidilution provisions, which are triggered in the event of certain stock splits, recapitalizations, or other dilutive transactions. In addition, issuances of common stock at a price below the conversion price then in effect (currently $0.2551), or the issuance of warrants, options, rights, or convertible securities which have an exercise price or conversion price less than that conversion price, other than for certain previously outstanding securities and certain “excluded securities” (as defined in the certificate of amendment), require the adjustment of the conversion price to that lower price at which shares of common stock have been issued or may be acquired. In the event that Andrea issues securities in the future which have a conversion price or exercise price which varies with the market price and the terms of such variable price are more favorable than the conversion price in the Series C Preferred Stock, the purchasers may elect to substitute the more favorable variable price when making conversions of the Series C Preferred Stock. | |||
| In accordance with Sub Topic 815-40, Andrea evaluated the Series C Preferred Stock and concluded that it is not indexed to the Company’s stock because of the conversion price adjustment feature described above. Accordingly, under the provisions of ASC 815, “Derivatives and Hedging” (“ASC 815”), Andrea evaluated the Series C Preferred Stock embedded conversion feature. The Company has concluded that the embedded conversion feature would be classified in stockholders’ equity if it were a freestanding instrument as the Series C Preferred Stock is more akin to equity and as such it should not be bifurcated from the Series C instrument and accounted for separately. | |||
| As of September 30, 2013, there were 44.231432 shares of Series C Preferred Stock outstanding, which were convertible into 2,023,658 shares of Common Stock and remaining accrued dividends of $73,921. | |||

| On February 17, 2004, Andrea entered into a Securities Purchase Agreement (including a Registration Rights Agreement) with certain holders of the Series C Preferred Stock and other investors (collectively, the “Buyers”) pursuant to which the Buyers agreed to invest a total of $2,500,000. In connection with this agreement, on February 23, 2004, the Buyers purchased, for a purchase price of $1,250,000, an aggregate of 1,250,000 shares of a new class of preferred stock, the Series D Preferred Stock, convertible into 5,000,000 shares of Common Stock (an effective conversion price of $0.25 per share) and Common Stock warrants exercisable for an aggregate of 2,500,000 shares of Common Stock. These warrants were exercisable at any time after August 17, 2004, at an exercise price of $0.38 per share. On February 23, 2009, these warrants expired without being exercised. | |||
| In addition, on June 4, 2004, the Buyers purchased for an additional $1,250,000, an additional 1,250,000 shares of Series D Preferred Stock convertible into 5,000,000 shares of Common Stock (an effective conversion price of $0.25 per share) and Common Stock warrants exercisable for an aggregate of 2,500,000 shares of Common Stock. The warrants were exercisable at any time after December 4, 2004 and before June 4, 2009 at an exercise price of $0.17 per share. On June 4, 2009, these warrants expired without being exercised. | |||
| The shares of Series D Preferred Stock are also subject to antidilution provisions, which are triggered in the event of certain stock splits, recapitalizations, or other dilutive transactions. In addition, issuances of common stock at a price below the conversion price then in effect (currently $0.25), or the issuance of warrants, options, rights, or convertible securities which have an exercise price or conversion price less than that conversion price, other than for certain previously outstanding securities and certain “excluded securities” (as defined in the certificate of amendment), require the adjustment of the conversion price to that lower price at which shares of common stock have been issued or may be acquired. In the event that Andrea issues securities in the future which have a conversion price or exercise price which varies with the market price and the terms of such variable price are more favorable than the conversion price in the Series D Preferred Stock, the purchasers may elect to substitute the more favorable variable price when making conversions of the Series D Preferred Stock. In addition, the Company is required to use its best efforts to secure the inclusion for quotation on the Over the Counter Bulletin Board for the common stock issuable under the Series D Preferred Stock and to arrange for at least two market makers to register with the Financial Industry Regulatory Authority. In the event that the holder of the Series D Preferred Stock and related warrants is unable to convert these securities into Andrea Common Stock, the Company shall pay to each such holder a Registration Delay Payment. This payment is to be paid in cash and is equal to the product of (i) the stated value of such Preferred Shares multiplied by (ii) the product of (1) .0005 multiplied by (2) the number of days that sales cannot be made pursuant to the Registration Statement (excluding any days during that may be considered grace periods as defined by the Registration Rights Agreement). | |||
| In accordance with Sub Topic 815-40, Andrea evaluated the Series D Preferred Stock and concluded that it is not considered to be indexed to the Company’s stock because of the conversion price adjustment feature described above. Accordingly, under the provisions of ASC 815, Andrea evaluated the Series D Preferred Stock embedded conversion feature. The Company has concluded that the embedded conversion feature would be classified in stockholders’ equity if it were a freestanding instrument as the Series D Preferred Stock is more akin to equity and as such it should not be bifurcated from the Series D instrument and accounted for separately. | |||
| As of September 30, 2013, there were 907,144 shares of Series D Preferred Stock outstanding which were convertible into 3,628,576 shares of Common Stock. | |||

| In 1998, the Board adopted the 1998 Stock Option Plan (“1998 Plan”), which was subsequently approved by the shareholders. The 1998 Plan, as amended, authorizes the granting of awards, the exercise of which would allow up to an aggregate of 6,375,000 shares of Andrea’s Common Stock to be acquired by the holders of those awards. The awards can take the form of stock options, stock appreciation rights, restricted stock, deferred stock, stock reload options or other stock-based awards. Awards may be granted to key employees, officers, directors and consultants. No further awards will be granted under the 1998 Plan. | |||||||||||||||||||||||||||||||||||
| In October 2006, the Board adopted the Andrea Electronics Corporation 2006 Equity Compensation Plan (“2006 Plan”), which was subsequently approved by the shareholders. The 2006 Plan, as amended, authorizes the granting of awards, the exercise of which would allow up to an aggregate of 18,000,000 shares of Andrea’s Common Stock to be acquired by the holders of those awards. The awards can take the form of stock options, stock appreciation rights, restricted stock or other stock-based awards. Awards may be granted to key employees, officers, directors and consultants. At September 30, 2013, there were 4,386,436 shares available for further issuance under the 2006 Plan. | |||||||||||||||||||||||||||||||||||
| The stock option awards granted under these plans have been granted with an exercise price equal to the market price of the Company’s stock at the date of grant; with vesting periods of up to four years and 10-year contractual terms. | |||||||||||||||||||||||||||||||||||
| The fair values of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model that uses the weighted-average assumptions. Expected volatilities are based on implied volatilities from historical volatility of the Company’s stock. The expected term of options granted represents the period of time that options granted are expected to be outstanding. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. | |||||||||||||||||||||||||||||||||||

| Loss Per Share | ' | |||||||||||||||||||||
| Loss Per Share — Basic loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding during the period. Diluted loss adjusts basic loss per share for the effects of convertible securities, stock options and other potentially dilutive financial instruments, only in the periods in which such effect is dilutive. Diluted earnings per share are based on the assumption that all dilutive convertible shares and stock options were converted or exercised. Dilution is computed by applying the treasury stock method for the outstanding options, and the if-converted method for the outstanding convertible instruments. Under the treasury stock method, options are assumed to be exercised at the beginning of the period (or at the time of issuance, if later) and as if funds obtained thereby were used to purchase common stock at the average market price during the period. Under the if-converted method, outstanding convertible instruments are assumed to be converted into common stock at the beginning of the period (or at the time of issuance, if later). Securities that could potentially dilute basic earnings per share (“EPS”) in the future that were not included in the computation of the diluted EPS because to do so would have been anti-dilutive for the periods presented, consist of the following: | ||||||||||||||||||||||

| Allowance for Doubtful Accounts | ' | |||||||||||||||||||||
| Allowance for Doubtful Accounts — The Company performs on-going credit evaluations of its customers and adjusts credit limits based upon payment history and the customer’s current credit worthiness, as determined by the review of their current credit information. Collections and payments from customers are continuously monitored. The Company maintains an allowance for doubtful accounts, which is based upon historical experience as well as specific customer collection issues that have been identified. While such bad debt expenses have historically been within expectations and allowances established, the Company cannot guarantee that it will continue to experience the same credit loss rates that it has in the past. If the financial condition of customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. | ||||||||||||||||||||||
| Inventories | ' | |||||||||||||||||||||
| Inventories — Inventories are stated at the lower of cost (on a first-in, first-out) or market basis. The cost of inventory is based on the respective cost of materials. Andrea reviews its inventory reserve for obsolescence on a quarterly basis and establishes reserves on inventories based on the specific identification method as well as a general reserve. Andrea records changes in inventory reserves as part of cost of revenues. | ||||||||||||||||||||||

| Intangible and Lived Assets | ' | |||||||||||||||||||||
| Intangible and Lived Assets — Andrea accounts for its long-lived assets in accordance with ASC 360 “Property, Plant and Equipment” for purposes of determining and measuring impairment of its long-lived assets (primarily intangible assets) other than goodwill. Andrea’s policy is to periodically review the value assigned to its long-lived assets to determine if they have been permanently impaired by adverse conditions which may affect Andrea. If Andrea identifies a permanent impairment such that the carrying amount of Andrea’s long lived assets are not recoverable using the sum of an undiscounted cash flow projection (gross margin dollars from product revenues), a new cost basis for the impaired asset will be established. If required, an impairment charge is recorded based on an estimate of future discounted cash flows. This new cost basis will be net of any recorded impairment. At September 30, 2013 and 2012, Andrea concluded that the Andrea DSP Microphone and Audio Software Products business segment was not required to be tested for recoverability. | ||||||||||||||||||||||
| Revenue Recognition | ' | |||||||||||||||||||||
| Revenue Recognition — Non software-related revenue, which is generally comprised of microphones and microphone connectivity product revenues, is recognized when title and risk of loss pass to the customer, which is generally upon shipment. With respect to licensing revenues, Andrea recognizes revenue in accordance with ASC 985, “Software” and ASC 605 “Revenue Recognition.” License revenue is recognized based on the terms and conditions of individual contracts. In addition, fee based services, which are short-term in nature, are generally performed on a time-and-material basis under separate service arrangements and the corresponding revenue is generally recognized as the services are performed. | ||||||||||||||||||||||
| During the three months ended March 31, 2013, it was determined that certain royalties related to a customer’s licensing agreement were not reported for 2012 and for the quarter ended March 31, 2013. The amount of unreported royalty revenue due to the Company was determined during the three months ended June 30, 2013. Since the Company was unable to estimate this amount at March 31, 2013, the Company did not record any revenue related to the unreported royalty revenue. During the three months ended June 30, 2013, the Company reported revenue of approximately $445,000, of which $295,000 and $150,000 consisted of royalties related to the licensing agreement from 2012 and for the quarter ended March 31, 2013, respectively. | ||||||||||||||||||||||
| Income Taxes | ' | |||||||||||||||||||||
| Income Taxes — Andrea accounts for income taxes in accordance with ASC 740, “Income Taxes” (“ASC 740”). ASC 740 requires an asset and liability approach for financial accounting and reporting for income taxes and establishes for all entities a minimum threshold for financial statement recognition of the benefit of tax positions, and requires certain expanded disclosures. The provision for income taxes is based upon income or loss after adjustment for those permanent items that are not considered in the | ||||||||||||||||||||||
| determination of taxable income. Deferred income taxes represent the tax effects of differences between the financial reporting and tax bases of the Company’s assets and liabilities at the enacted tax rates in effect for the years in which the differences are expected to reverse. The Company evaluates the recoverability of deferred tax assets and establishes a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Andrea expects it will reduce its valuation allowance in future periods to the extent that it can demonstrate its ability to utilize the assets. Management makes judgments as to the interpretation of the tax laws that might be challenged upon an audit and cause changes to previous estimates of tax liability. In management’s opinion, adequate provisions for income taxes have been made for all years. If actual taxable income by tax jurisdiction varies from estimates, additional allowances or reversals of reserves may be necessary. Income tax expense consists of the tax payable for the period and the change during the period in deferred tax assets and liabilities. The Company has identified its federal tax return and its state tax return in New York as “major” tax jurisdictions. Based on the Company’s evaluation, it has been concluded that there are no significant uncertain tax positions requiring recognition in the Company’s condensed consolidated interim financial statements. The Company’s evaluation was performed for tax years ended 2009 through 2012. The Company believes that its income tax positions and deductions will be sustained on audit and does not anticipate any adjustments that will result in a material change to its financial position. | ||||||||||||||||||||||
| The provision for income taxes for the three months ended September 30, 2013 of approximately $128,000 is a result of certain licensing revenues that are subject to withholding of income tax as mandated by the foreign jurisdiction in which the revenues are earned. Although this provision could be offset by future tax benefits since the Company records a full valuation against deferred tax assets, the provision of approximately $128,000 will not be reduced by such tax benefits. Additionally, approximately $87,000 of the provision recorded for the three months ended September 30, 2013 relates to royalty revenue reported during the three months ended June 30, 2013. At the time the revenue was reported, the Company was unaware that some portion of this revenue would be subject to foreign income tax as this income was previously exempt from foreign taxes. The provision for income taxes for the three months ended September 30, 2012 of approximately $155,000 is the result of increasing the valuation allowance against our deferred tax assets after considering changes in previously existing positive and negative evidence of the Company’s ability to utilize those deferred tax assets. | ||||||||||||||||||||||
| Stock-Based Compensation | ' | |||||||||||||||||||||
| Stock-Based Compensation — At September 30, 2013, Andrea had two stock-based employee compensation plans, which are described more fully in Note 6. Andrea accounts for stock-based compensation in accordance with ASC 718, “Compensation — Stock Compensation” (“ASC 718”). ASC 718 establishes accounting for stock-based awards exchanged for employee services. Under the provisions of ASC 718, stock-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the employee’s requisite service period (generally the vesting period of the equity grant). The fair value of the Company’s common stock options are estimated using the Black Scholes option-pricing model with the following assumptions: expected volatility, dividend rate, risk free interest rate and the expected life. The Company expenses stock-based compensation by using the straight-line method. In accordance with ASC 718, excess tax benefits realized from the exercise of stock-based awards are classified in cash flows from financing activities. The future realization of the reserved deferred tax assets related to these tax benefits associated with the exercise of stock options will result in a credit to additional paid in capital if the related tax deduction reduces taxes payable. The Company has elected the “with and without approach” regarding ordering of windfall tax benefits to determine whether the windfall tax benefit did reduce taxes payable in the current year. Under this approach, the windfall tax benefit would be recognized in additional paid-in-capital only if an incremental tax benefit is realized after considering all other benefits presently available. | ||||||||||||||||||||||
| Use of Estimates | ' | |||||||||||||||||||||
| Use of Estimates — The preparation of condensed consolidated interim 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, liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated interim financial statements and the reported amounts of revenues and expenses during the reporting period. | ||||||||||||||||||||||
| Management bases its estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. The most significant estimates, among other things, are used in accounting for allowances for bad debts, inventory valuation and obsolescence, product warranty, depreciation, deferred income taxes, expected realizable values for assets (primarily intangible assets), contingencies, revenue recognition as well as the recording and presentation of the Company’s convertible preferred stock. Estimates and assumptions are periodically reviewed and the effects of any material revisions are reflected in the condensed consolidated interim financial statements in the period that they are determined to be necessary. Actual results could differ from those estimates and assumptions. | ||||||||||||||||||||||
| Subsequent Events | ' | |||||||||||||||||||||
| Subsequent Events — The Company evaluates events that occurred after the balance sheet date but before the condensed consolidated interim financial statements are issued. Based upon the evaluation, except as noted in Note 6, the Company did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the condensed consolidated interim financial statements. | ||||||||||||||||||||||
