Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | 1. NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES Nature of Business ® ® The Company participates, either directly or indirectly, in 19 active joint venture arrangements in North America, Europe and Asia. Each of these joint ventures generally manufactures and markets products in the geographic territory to which it is assigned. While most of the Company’s joint ventures exclusively sell rust and corrosion inhibiting products, some of the joint ventures also sell the Company’s Natur-Tec ® The Company has evaluated events occurring after the date of the consolidated financial statements for events requiring recording or disclosure in the financial statements. Principles of Consolidation Non-Controlling Interests Reclassification - Net Sales Revenue Recognition Trade Receivable The following table is a tabular rollforward for the allowance for doubtful accounts: August 31, 2012 $ 20,000 Bad debts 21,000 Adjustment to provision (21,000 ) August 31, 2013 $ 20,000 Bad debts 107,000 Adjustment to provision (87,000 ) August 31, 2014 40,000 Bad debts 6,000 Adjustment to provision (6,000 ) August 31, 2015 $ 40,000 Trade Receivables from Joint Ventures Fees for Services Provided to Joint Ventures – Cash and Cash Equivalents Available for Sale Securities Inventories Property and Depreciation Buildings and improvements (years) 5 - 30 Machinery and equipment (years) 3 - 10 Investments in Joint Ventures Recoverability of Long-Lived Assets Income Taxes The Company records net deferred tax assets to the extent the Company believes these assets will more likely than not be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. In the event the Company determines that it would be able to realize its deferred income tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The Company records uncertain tax positions on the basis of a two-step process whereby the Company determines whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position and those tax positions that meet the more-likely-than-not recognition threshold. The Company recognizes the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the related tax authority. Foreign Currency Translation (Accumulated Other Comprehensive Income (Loss)) The Company (excluding NTIC China, Zerust Brazil, Natur-Tec India, NTI Asean and its joint ventures) conducts all foreign transactions based on the U.S. dollar. Since investments in joint ventures are accounted for using the equity method, any changes in foreign currency exchange rates are reflected as a foreign currency translation adjustment and does not change the equity in income from joint ventures reflected in the Company’s consolidated statements of operations.

NTI ASEAN NTI Asean is an entity that holds investments in eight entities operating in the Association of Southeast Asian Nations (ASEAN) region, including the following countries: China (although the joint venture agreements for the Chinese joint venture were terminated as of December 31, 2014 and liquidation of this joint venture is anticipated), Indonesia, Korea, Malaysia, Philippines, Singapore, Taiwan and Thailand. Prior to September 1, 2012, the Company owned 50% of the equity and voting rights of NTI Asean and accounted for its investment using the equity method, as its ownership was considered to be less than a majority.

The Company accounted for the transaction resulting in the additional ownership as a business combination. Beginning in the first quarter of fiscal 2013, the Company consolidated the results of NTI Asean. Immediately prior to the transaction, the Company re-measured the fair value of NTI Asean and determined that there was no difference between the fair value and the book value of the entity. As a result, there was no accounting impact related to the business combination in the consolidated statements of operations. The Company determined the fair value of NTI Asean using the capitalized income method, including a capitalization rate of 25%.

Since December 31, 2014, the Company has conducted business in China through a wholly-owned subsidiary, NTIC (Shanghai) Co. Ltd. As of December 31, 2014, the Company started recognizing Tianjin Zerust based on its carrying value instead of the equity method since the Company no longer expects to significantly affect the joint venture’s operations or decision making. See Note 8. Because of the lack of financial and other information received from Tianjin Zerust, it is possible that receipt of future financial and other information from Tianjin Zerust may impact the realization of NTIC’s investment in and realization of a receivable from Tianjin Zerust. The last time the Company received financial information from Tianjin Zerust was through November 2014. NTIC as of August 31, 2015, does not believe there are any triggering events that would require an impairment test. NTIC’s current net investment is approximately $1.1 million, which is 60% of its investment in Tianjin Zerust, which was $1,883,668 as of August 31, 2015. The Company will continue to evaluate the realization of this asset on an ongoing basis and adjust if necessary. The Company records expenses that are directly attributable to the joint ventures on its consolidated statements of operations in the line item “Expenses incurred in support of joint ventures.” The expenses include items such as employee compensation and benefit expenses, travel expense and consulting expense. The Company did not make any joint venture investments during fiscal 2015. On May 31, 2014, NTI Asean purchased the other 50% ownership interest in its joint venture in Singapore for $110,988. The Company did not make any other joint venture investments during fiscal 2014. On November 30, 2013, the Company agreed to sell its indirect ownership interest in Mütec GmbH (Mütec), the Company’s former joint venture in Germany which manufactures proprietary electronic sensing instruments. In connection with the transaction, the owner of Mütec borrowed $168,000 from the Company to be repaid over four years with no interest. As of August 31, 2015 and August 31, 2014, $125,891 and $156,854 was due to the Company related to this transaction. |

Fair Value Disclosures [Text Block] | 8. CHINA OPERATIONS Effective December 31, 2014, the Company terminated its joint venture agreements with its previous joint venture in China, Tianjin Zerust, began the process of liquidating the joint venture entity, and commenced operations in China through a wholly-owned subsidiary, NTIC (Shanghai) Co. Ltd. on January 1, 2015. Effective December 31, 2014, the Company’s investment in Tianjin Zerust is reported at carrying value based on the Company’s decreased level of influence over the entity, and the Company has reclassified previously unrecognized gains on foreign currency translation from accumulated other comprehensive income. Any declines in the fair value are reflected as adjustments to the carrying value. No such adjustments were recorded during fiscal 2015. The investment in Tianjin Zerust is as follows: Investment Equity method investment – August 31, 2014 $ 2,243,524 Equity in earnings – fiscal year 2015 132,824 Reclassification of translation gains on foreign currency translation (492,680 ) Investment at carrying value – August 31, 2015 $ 1,883,668 The Company incurred expenses of $1,642,258 during fiscal 2015 related to the termination of the joint venture agreement with Tianjin Zerust, the initiation of the liquidation of Tianjin Zerust and the formation and initial operation of NTIC China. Such expenses consisted primarily of legal expenses and personnel expenses associated with the establishment of the subsidiary and the hiring of new personnel. These expenses are recorded as operating expenses on the consolidated statements of operations and are partially off-set by the gross margin contribution from sales of NTIC China. Because of the lack of financial and other information received from Tianjin Zerust, it is possible that if and when financial and other information is received from Tianjin Zerust that the Company may need to recognize an impairment charge on its investment in Tianjin Zerust. The Company estimates that its maximum exposure in terms of an impairment charge would be approximately $1,130,200 on its investment in Tianjin Zerust, or 60% of the entire investment at carrying value, which was $1,883,668 as of August 31, 2015. |

Earnings Per Share [Text Block] | 11. NET INCOME PER COMMON SHARE Basic net income per common share is computed by dividing net income by the weighted average number of common shares outstanding. Diluted net income per share assumes the exercise of stock options using the treasury stock method, if dilutive. Options to purchase shares of common stock of 45,067 and 22,000 were excluded from the computation of common share equivalents for fiscal 2015, 2014 and 2013, respectively, as the exercise prices of such options were greater than market price of a share of common stock. The following is a reconciliation of the earnings per share computation: Numerator: August 31, 2015 August 31, 2014 August 31, 2013 Net income attributable to NTIC $ 1,789,571 $ 4,106,372 $ 3,366,894 Denominator: Basic-weighted shares outstanding 4,521,788 4,454,836 4,421,636 Weighted shares assumed upon exercise of stock options 127,272 124,662 54,259 Diluted – weighted shares outstanding 4,649,060 4,579,498 4,475,895 Basic earnings per share: $ 0.40 $ 0.92 $ 0.76 Diluted earnings per share: $ 0.38 $ 0.90 $ 0.75 The dilutive impact summarized above relates to the periods when the average market price of Company stock exceeded the exercise price of the potentially dilutive option securities granted. Earnings per common share were based on the weighted average number of common shares outstanding during the periods when computing the basic earnings per share. When dilutive, stock options are included as equivalents using the treasury stock market method when computing the diluted earnings per share. |

Disclosure of Compensation Related Costs, Share-based Payments [Text Block] | 12. STOCK-BASED COMPENSATION The Company has two stock-based compensation plans under which stock options and other stock-based awards have been granted, the Northern Technologies International Corporation Amended and Restated 2007 Stock Incentive Plan (the 2007 Plan) and the Northern Technologies International Corporation Employee Stock Purchase Plan (the ESPP). The Compensation Committee of the Board of Directors and the Board of Directors administer these plans. The 2007 Plan provides for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock, stock unit awards, performance awards and stock bonuses to eligible recipients to enable the Company and its subsidiaries to attract and retain qualified individuals through opportunities for equity participation in the Company, and to reward those individuals who contribute to the achievement of the Company’s economic objectives. Subject to adjustment as provided in the 2007 Plan, up to a maximum of 800,000 shares of the Company’s common stock are issuable under the 2007 Plan. Options granted under the 2007 Plan generally have a term of ten years and become exercisable over a three- or four-year period beginning on the one-year anniversary of the date of grant. Options are granted at per share exercise prices equal to the market value of the Company’s common stock on the date of grant. The Company issues new shares upon the exercise of options. As of August 31, 2015, only stock options and stock bonuses had been granted under the 2007 Plan. The maximum number of shares of common stock of the Company available for issuance under the ESPP is 100,000 shares, subject to adjustment as provided in the ESPP. The ESPP provides for six-month offering periods beginning on September 1 and March 1 of each year. The purchase price of the shares is 90% of the lower of the fair market value of common stock at the beginning or end of the offering period. This discount may not exceed the maximum discount rate permitted for plans of this type under Section 423 of the Internal Revenue Code of 1986, as amended. The ESPP is compensatory for financial reporting purposes. The fair value of option grants is determined at date of grant, using the Black-Scholes option pricing model with the assumptions listed below. The volatility factor used in the Black-Scholes option pricing model is based on historical stock price fluctuations and the risk-free interest rate is based on U.S. treasury rates appropriate for the expected term. Dividend yield and expected volatility are estimated using historical amounts that are anticipated to be consistent with current values. Expected life of the option is based on the life of the option agreements. Based on these valuations, the Company recognized compensation expense of $495,683, $454,015 and $306,451 during fiscal 2015, 2014 and 2013, respectively, related to the options that vested during such time period. As of August 31, 2015, the total compensation cost for non-vested options not yet recognized in the Company’s consolidated statements of operations was $259,585. Stock-based compensation expense of $179,785 and $79,800 is expected to be recognized during fiscal 2016 and 2017, based on outstanding options as of August 31, 2015. Future option grants will impact the compensation expense recognized. Stock-based compensation expense is included in general and administrative expense on the consolidated statements of operations. The Company currently estimates a ten percent forfeiture rate for stock options, and will continue to review this estimate in future periods. The fair value of each option grant is estimated on the grant date using the Black-Scholes option-pricing model with the following assumptions and results for the grants: August 31, 2015 August 31, 2014 August 31, 2013 Dividend yield 0.00 % 0.00 % 0.00% Expected volatility 46.6 % 47.4 % 48.0% Expected life of option (years) 10 10 5 - 10 Weighted average risk-free interest rate 1.63 % 1.39 % 0.71% Stock option activity during the periods indicated is as follows: Number of Shares (#) Weighted Average Exercise Price Aggregate Outstanding at August 31, 2012 203,873 $ 10.01 Options granted 118,294 10.25 Options exercised (37,040 ) 9.96 Options exercised (24,500 ) 13.12 Outstanding at August 31, 2013 260,627 $ 9.84 Options granted 56,373 14.83 Options exercised (74,000 ) 7.82 Options terminated (4,000 ) 8.57 Outstanding at August 31, 2014 239,000 11.66 Options granted 45,067 20.10 Options exercised (38,333 ) 9.00 Options terminated (4,000 ) 10.20 Outstanding at August 31, 2015 241,734 $ 13.72 $ 677,475 Exercisable at August 31, 2015 160,453 $ 12.13 $ 577,528 The weighted average per share fair value of options granted during fiscal 2015, 2014 and 2013 was $11.58, $8.57, and $5.53, respectively.

The Company’s portion of the cumulative undistributed earnings of foreign joint ventures that are essentially permanent in duration were $18,483,377, $20,540,523 and $22,281,510 at August 31, 2015, 2014 and 2013, respectively. During fiscal 2015, the Company recorded deferred income tax expense of $79,000 representing foreign withholding taxes to be paid with respect to the portion of the cumulative undistributed earnings of foreign joint ventures that it determined were not essentially permanent in duration. If some or all of the undistributed earnings of the joint ventures are remitted to the Company in the future, income taxes, if any, after the application of foreign tax credits will be provided at that time. To the extent undistributed earnings of the Company’s joint ventures are distributed in the future, it is not expected to result in any material additional U.S. income tax liability after the application of foreign tax credits. The tax effect of the temporary differences and tax carryforwards comprising the net deferred taxes shown on the consolidated balance sheets at August 31, 2015 and 2014 are as follows: August 31, 2015 2014 Current: Accrued bonus $ 174,000 $ 524,000 Allowance for doubtful accounts 14,500 14,500 Inventory costs 81,200 100,800 Prepaid expenses and other (41,800 ) (40,600 ) Other accrued expenses 102,100 86,800 Deferred joint venture expenses 93,200 104,100 Total current $ 424,100 $ 789,600 Noncurrent: Property and equipment $ (204,000 ) $ (171,200 ) Goodwill 19,400 27,300 Other intangible assets 1,103,800 825,200 Nonqualified stock options 308,900 260,400 Foreign net operating loss carryforward 26,800 - Capital loss carryforward - 50,900 Foreign tax credit carryforward 4,654,800 4,141,100 Investment in foreign joint ventures (79,000 ) - Research and development credit 2,224,600 1,910,800 New hire retention credit 10,600 10,600 8,065,900 7,055,100 Valuation allowance (6,889,900 ) (6,113,400 ) Total noncurrent 1,176,000 941,700 At August 31, 2015, the Company had foreign tax credit carryforwards of approximately $4,654,800, of which approximately $187,400 will expire if not utilized by August 31, 2016. In addition, the Company had federal and state tax credit carryforwards of $2,235,200 at August 31, 2015 which begin to expire in fiscal 2019. These federal and state tax credit carryforwards consist primarily of federal and Minnesota research and development credit carryforwards. The Company also has foreign net operating loss carryforwards of $26,800 at August 31, 2015 which begin to expire in fiscal 2020. As of August 31, 2015, the Company recorded a valuation allowance of $4,654,800 with respect to the foreign tax credit carryforwards. In addition, the Company has recorded a valuation allowance of $2,335,100 with respect to federal and state tax credit carryforwards. As of August 31, 2014, the Company recorded a valuation allowance of $4,141,100 with respect to the foreign tax credit carryforwards. In addition, the Company has recorded a valuation allowance of $1,919,800 with respect to federal and state tax credit carryforwards. The Company records a tax valuation allowance to reduce deferred tax assets to the amount expected to be realized when it is more likely than not that some portion or all of its deferred tax assets will not be realized. The Company determined based on all available evidence, including historical data and projections of future results, that it is more likely than not that all of its deferred tax assets, except for its foreign tax credit carryforward, federal and Minnesota research and development credit carryforwards, and capital loss carryforwards will be fully realized. The Company determined that its deferred tax asset related to foreign tax credit carryforwards will not be realized due to insufficient federal taxable income within the carryforward period and the fact that for ordering purposes the foreign tax credit carryforwards are not allowed to be used until after any current year foreign tax credits are utilized. In addition, based on historical data and future projections, the Company determined that it is more likely than not that its deferred tax asset related to federal and Minnesota research and development credit carryforwards will not be realized due to insufficient federal and Minnesota taxable income within the carryforward period after considering the foreign tax credit usage. The following table is a tabular rollforward for the valuation allowance: August 31, 2012 $ 4,933,100 Adjustment to valuation allowance 1,153,000 August 31, 2013 $ 6,086,100 Adjustment to valuation allowance 27,300 August 31, 2014 6,113,400 Adjustment to valuation allowance 776,500 August 31, 2015 $ 6,889,900 The following is a tabular reconciliation of the total amounts of unrecognized tax benefits: Fiscal Year Ended August 31, 2015 2014 Gross unrecognized tax benefits – beginning balance $ 180,000 $ 170,000 Gross increases - prior period tax positions 15,000 2,000 Gross increases – current period tax positions 8,000 8,000 Gross unrecognized tax benefits – ending balance $ 203,000 $ 180,000 The entire amount of unrecognized tax benefits would affect the effective tax rate. It is not expected that the amount of unrecognized tax benefits will change significantly in the next 12 months. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of the Company’s income tax provision. Accrued interest and penalties are included within the related tax liability line in the consolidated balance sheet. There was no liability for the payment of interest and penalties at both August 31, 2015 and August 31, 2014. The Company is subject to taxation in the United States and various states and foreign jurisdictions. With few exceptions, as of August 31, 2015, the Company is no longer subject to federal, state, local, or foreign examinations by tax authorities for years prior to August 31, 2012. |

Commitments and Contingencies Disclosure [Text Block] | 18. COMMITMENTS AND CONTINGENCIES On August 18, 2015, the Compensation Committee of the Board of Directors of the Company approved the material terms of an annual bonus plan for the Company’s executive officers as well as certain officers and employees for the fiscal year ending August 31, 2016. For fiscal 2016 as in past years, the total amount available under the bonus plan for all plan participants, including executive officers, is dependent upon the Company’s earnings before interest, taxes and other income, as adjusted to take into account amounts to be paid under the bonus plan and certain other adjustments (Adjusted EBITOI). Each plan participant’s percentage of the overall bonus pool is based upon the number of plan participants, the individual’s annual base salary and the individual’s position and level of responsibility within the company. In the case of each of the Company’s executive officer participants, 75% of the amount of their individual bonus payout will be determined based upon the Company’s actual EBITOI for fiscal 2016 compared to a pre-established target EBITOI for fiscal 2016 and 25% of the payout will be determined based upon such executive officer’s achievement of certain pre-established individual performance objectives. The payment of bonuses under the plan are discretionary and may be paid to executive officer participants in both cash and shares of NTIC common stock, the exact amount and percentages will be determined by the Company’s Board of Directors, upon recommendation of the Compensation Committee, after the completion of the Company’s consolidated financial statements for fiscal 2016. On August 19, 2014, the Compensation Committee of the Board of Directors of the Company approved the material terms of an annual bonus plan for the Company’s executive officers as well as certain officers and employees for the fiscal year ending August 31, 2015. For fiscal 2015 as in past years, the total amount available under the bonus plan for all plan participants, including executive officers, was dependent upon the Company’s Adjusted EBITOI. Each plan participant’s percentage of the overall bonus pool was based upon the number of plan participants, the individual’s annual base salary and the individual’s position and level of responsibility within the company. In the case of each of the Company’s executive officer participants, 75% of the amount of their individual bonus payout was determined based upon the Company’s actual EBITOI for fiscal 2015 compared to a pre-established target EBITOI for fiscal 2015 and 25% of the payout was determined based upon such executive officer’s achievement of certain pre-established individual performance objectives. Accrued bonuses as of August 31, 2015 and 2014 were $620,000 and $1,460,000, respectively. Four joint ventures (consisting of the Company’s joint venture in Korea, India, Thailand and Tianjin Zerust) accounted for 67.0% of the Company’s trade joint venture receivables at August 31, 2015. Three joint ventures (consisting of the Company’s joint ventures in Korea, Thailand and Tianjin Zerust) accounted for 62.9% of the Company’s trade joint venture receivables at August 31, 2014. On March 23, 2015, the Company and NTI Asean filed a lawsuit in Tianjin No 1 Intermediate People’s Court against two individuals, Meng Tao and Xu Hui, related to breaches of duties and contractual commitments owed to NTI Asean under certain agreements related to the Company’s former joint venture in China, Tianjin Zerust Anti-Corrosion Technologies Ltd (Tianjin Zerust). The lawsuit alleges, among other things, that Mr. Meng Tao and Xu Hui have engaged in self-dealing, usurped business opportunities, and received economic benefits that were required to go to Tianjin Zerust. As of August 31, 2015, the Company is not able to reasonably estimate the amount of any recovery to NTI Asean, if any. On April 21, 2015, the Company and NTI Asean initiated a lawsuit in the District Court for the Second Judicial District, County of Ramsey, State of Minnesota against Cortec Corporation alleging, among other things, that Cortec Corporation aided and abetted breaches of duties and contractual commitments owed to the Company and NTI Asean related to the Company’s joint venture in China, Tianjin Zerust. From time to time, the Company is subject to various claims and legal actions in the ordinary course of its business. The Company records a liability in its consolidated financial statements for costs related to claims, including future legal costs, settlements and judgments, where the Company has assessed that a loss is probable and an amount can be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when no amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is not probable or the amount is not estimable, or both, if there is a reasonable possibility that material loss may be have been incurred. In the opinion of management, as of August 31, 2015, the amount of liability, if any, with respect to these matters, individually or in the aggregate, will not materially affect the Company’s consolidated results of operations, financial position or cash flows. |

Fair Value, Measurement Inputs, Disclosure [Text Block] | 20. Fair Value Measurements The Company follows the authoritative guidance on fair value measurements and disclosures with respect to assets and liabilities that are measured at fair value on both a recurring and non-recurring basis. Under this guidance, fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The authoritative guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability, developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The categorization of financial assets and financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is broken down into three levels defined as follows: Level 1 - Inputs are quoted prices in active markets for identical assets or liabilities. Level 2 - Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3 - Inputs are unobservable for the asset or liability. See the section below titled Valuation Techniques for further discussion of how the Company determines fair value for investments. Assets and Liabilities That Are Measured at Fair Value on a Recurring Basis Assets and liabilities that are measured at fair value on a recurring basis primarily relate to marketable equity securities. These items are marked-to-market at each reporting period. The following tables provide information by level for assets and liabilities that are measured at fair value on a recurring basis: Fair Value Measurements Fair value as of Level 1 Level 2 Level 3 Available for sale securities $ 2,027,441 $ 2,027,441 $ — $ — Fair Value Measurements Fair value as of Level 1 Level 2 Level 3 Available for sale securities $ 5,519,766 $ 5,519,766 $ — $ — Valuation Techniques Financial assets that are classified as Level 1 securities include cash equivalents and as of August 31, 2015, available for sale securities. These are valued using quoted market prices in an active market. The Company reviews the fair value hierarchy classification on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy. The Company’s policy is to recognize transfers into and out of levels within the fair value hierarchy at the end of the fiscal quarter in which the actual event or change in circumstances that caused the transfer occurs. There were no transfers between Level 1, Level 2, or Level 3 during the fiscal years ended August 31, 2015 or August 31, 2014. When a determination is made to classify an asset or liability within Level 3, the determination is based upon the significance of the unobservable inputs to the overall fair value measurement. |

Income Tax, Policy [Policy Text Block] | Income Taxes The Company records net deferred tax assets to the extent the Company believes these assets will more likely than not be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. In the event the Company determines that it would be able to realize its deferred income tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The Company records uncertain tax positions on the basis of a two-step process whereby the Company determines whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position and those tax positions that meet the more-likely-than-not recognition threshold. The Company recognizes the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the related tax authority. |
