Nature of Operations and Continuance of Business [Text Block]	'
	1	Nature of Operations and Continuance of Business
		The Company was incorporated in the State of Nevada on January 22, 2007 to acquire and commercially exploit various new energy related technologies through licenses and purchases. On December 8, 2008, the Company continued its corporate jurisdiction out of the State of Nevada and into the province of British Columbia, Canada. The Company is in the business of developing and providing energy alternatives. The Company also provides marketing and graphic design services to help companies optimize their environmental awareness presence through the eyes of government, industry and the general public.
		These consolidated financial statements have been prepared on a going concern basis, which implies the Company will continue to realize its assets and discharge its liabilities in the normal course of business. The Company has yet to acquire commercially exploitable energy related technology, and is unlikely to generate earnings in the immediate or foreseeable future. The continuation of the Company as a going concern is dependent upon the continued financial support from its shareholders, the ability of management to raise additional equity capital through private and public offerings of its common stock, and the attainment of profitable operations. As at May 31, 2014, the Company has accumulated losses of $9,314,295 since inception. These factors raise substantial doubt regarding the Company’s ability to continue as a going concern. These consolidated financial statements do not include any adjustments to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.
		Management requires additional funds over the next twelve months to fully implement its business plan. Management is currently seeking additional financing through the sale of equity and from borrowings from private lenders to cover its operating expenditures. There can be no certainty that these sources will provide the additional funds required for the next twelve months.

Significant Accounting Policies [Text Block]	'
	2	Significant Accounting Policies
		(a)	Basis of Presentation/Principles of Consolidation
			These consolidated financial statements and related notes are presented in accordance with accounting principles generally accepted in the United States. These consolidated financial statements include the accounts of the Company and its subsidiaries, Carbon Commodity Corporation, Climate ESCO Ltd., Mantra Energy Alternatives Ltd., Mantra China Inc., Mantra China Limited, Mantra Media Corp., Mantra NextGen Power Inc., and Mantra Wind Inc. All the subsidiaries are wholly-owned with the exception of Climate ESCO Ltd., which is 64.84% owned and Mantra Energy Alternatives Ltd., which is 89.09% owned. All inter- company balances and transactions have been eliminated.
		(b)	Use of Estimates
			The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company regularly evaluates estimates and assumptions related to allowance for doubtful accounts, the estimated useful lives and recoverability of long-lived assets, valuation of inventory, equity component of convertible debt, stock-based compensation, and deferred income tax asset valuation allowances. The Company bases its estimates and assumptions on current facts, historical experience and various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the accrual of costs and expenses that are not readily apparent from other sources. The actual results experienced by the Company may differ materially and adversely from the Company’s estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected.
		(c)	Cash and Cash Equivalents
			The Company considers all highly liquid instruments with maturity of three months or less at the time of issuance to be cash equivalents.
		(d)	Accounts Receivable
			The Company recognizes allowances for doubtful accounts to ensure accounts receivable are not overstated due to the inability or unwillingness of its customers to make required payments. The allowance is based on historical bad debt expense, the age of receivable and the specific identification of receivables the Company considers at risk.
		(e)	Property and Equipment
			Property and equipment are stated at cost. The Company depreciates the cost of property and equipment over their estimated useful lives at the following annual rates:
		Automotive	3 years straight-line basis
		Computer equipment	3 years straight-line basis
		Leasehold improvements	5 years straight-line basis
		Office equipment and furniture	5 years straight-line basis
		Research equipment	5 years straight-line basis
		(f)	Intangible Assets
			Intangible assets consist of patents and are stated at cost and have a definite life. Intangible assets are amortized over their estimated useful lives. The Company periodically evaluates the reasonableness of the useful lives of these assets. Once these assets are fully amortized, they are removed from the accounts. These assets are reviewed for impairment or obsolescence when events or changes in circumstances indicate that the carrying amount may not be recoverable. If impaired, intangible assets are written down to fair value based on discounted cash flows or other valuation techniques. The Company has no intangibles with indefinite lives.
		(g)	Long-lived Assets
			In accordance with ASC 360, “ Property, Plant and Equipment ”, the Company tests long-lived assets or asset groups for recoverability when events or changes in circumstances indicate that their carrying amount may not be recoverable. Circumstances which could trigger a review include, but are not limited to: significant decreases in the market price of the asset; significant adverse changes in the business climate or legal factors; accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of the asset; current period cash flow or operating losses combined with a history of losses or a forecast of continuing losses associated with the use of the asset; and current expectation that the asset will more likely than not be sold or disposed significantly before the end of its estimated useful life. Recoverability is assessed based on the carrying amount of the asset and its fair value, which is generally determined based on the sum of the undiscounted cash flows expected to result from the use and the eventual disposal of the asset, as well as specific appraisal in certain instances. An impairment loss is recognized when the carrying amount is not recoverable and exceeds fair value.
		(h)	Foreign Currency Translation
			Transactions in foreign currencies are translated into the currency of measurement at the exchange rates in effect on the transaction date. Monetary balance sheet items expressed in foreign currencies are translated into U.S. dollars at the exchange rates in effect at the balance sheet date. The resulting exchange gains and losses are recognized in income.
			The Company’s integrated foreign subsidiaries are financially or operationally dependent on the Company. The Company uses the temporal method to translate the accounts of its integrated operations into U.S. dollars. Monetary assets and liabilities are translated at the exchange rates in effect at the balance sheet date. Non-monetary assets and liabilities are translated at historical rates. Revenues and expenses are translated at average rates for the period, except for amortization, which is translated on the same basis as the related asset. The resulting exchange gains or losses are recognized in income.
		(i)	Income Taxes
			The Company accounts for income taxes using the asset and liability method in accordance with ASC 740, “ Accounting for Income Taxes ”. The asset and liability method provides that deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized.
			As of May 31, 2014 and 2013, the Company did not have any amounts recorded pertaining to uncertain tax positions.
			The Company files federal and provincial income tax returns in Canada and federal, state and local income tax returns in the U.S., as applicable. The Company may be subject to a reassessment of federal and provincial income taxes by Canadian tax authorities for a period of three years from the date of the original notice of assessment in respect of any particular taxation year. For Canadian and U.S. income tax returns, the open taxation years range from 2010 to 2014. In certain circumstances, the U.S. federal statute of limitations can reach beyond the standard three year period. U.S. state statutes of limitations for income tax assessment vary from state to state. Tax authorities of Canada and U.S. have not audited any of the Company’s, or its subsidiaries’, income tax returns for the open taxation years noted above.
			The Company recognizes interest and penalties related to uncertain tax positions in tax expense. During the years ended May 31, 2014 and 2013, there were no charges for interest or penalties.
		(j)	Technology Development Revenue Recognition
			The Company performs research and development services. The Company recognizes revenue under research contracts when a contract has been executed, the contract price is fixed and determinable, delivery of services or products has occurred, and collectability of the contract price is considered reasonably assured and can be reasonably estimated. Revenue is based on direct labor hours expended at contract billing rates plus other billable direct costs.
		(k)	Financial Instruments and Fair Value Measures
			ASC 820, “ Fair Value Measurements and Disclosures ” requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. ASC 820 prioritizes the inputs into three levels that may be used to measure fair value:
	Level 1
	Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.
	Level 2
	Level 2 applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.
	Level 3
	Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.
	The Company’s financial instruments consist principally of cash, amounts receivable, accounts payable and accrued liabilities, loans payable, convertible debentures, obligations under capital lease, and amounts due to related parties. Pursuant to ASC 820, the fair value of cash is determined based on “Level 1” inputs, which consist of quoted prices in active markets for identical assets. The recorded values of all other financial instruments approximate their current fair values because of their nature and respective maturity dates or durations.
		(l)	Research and Development Costs
			Research and development costs are expensed as incurred.
		(m)	Stock-based Compensation
			The Company records stock-based compensation in accordance with ASC 718, “ Compensation – Stock Compensation ”, using the fair value method. All transactions in which goods or services are the consideration received for the issuance of equity instruments are accounted for based on the fair value of the consideration received or the fair value of the equity instrument issued, whichever is more reliably measurable.
			The Company uses the Black-Scholes option pricing model to calculate the fair value of stock-based awards. This model is affected by the Company’s stock price as well as assumptions regarding a number of subjective variables. These subjective variables include, but are not limited to the Company’s expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors. The value of the portion of the award that is ultimately expected to vest is recognized as an expense in the consolidated statement of operations over the requisite service period.
		(n)	Loss Per Share
			The Company computes loss per share in accordance with ASC 260, " Earnings per Share " which requires presentation of both basic and diluted earnings per share (“EPS”) on the face of the income statement. Basic EPS is computed by dividing the loss available to common shareholders (numerator) by the weighted average number of shares outstanding (denominator) during the period. Diluted EPS gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method and convertible preferred stock using the if-converted method. In computing diluted EPS, the average stock price for the period is used in determining the number of shares assumed to be purchased from the exercise of stock options or warrants. Diluted EPS excludes all dilutive potential shares if their effect is anti dilutive. As at May 31, 2014, the Company had 10,904,755 (2013 – 10,329,619) dilutive potential shares outstanding.
		(o)	Comprehensive Loss
			ASC 220, “ Comprehensive Income ,” establishes standards for the reporting and display of comprehensive loss and its components in the financial statements. As at May 31, 2014 and 2013, the Company has no items that represent a comprehensive loss and, therefore, has not included a schedule of comprehensive loss in the consolidated financial statements.

		(a)	On September 2, 2009, the Company entered into an agreement with a company to acquire a worldwide, exclusive license for the Mixed Reactant Flow-By Fuel Cell technology. The term of the agreement is for twenty years or the expiry of the last patent licensed under the agreement, whichever is later. The Company agreed to pay the licensor the following license fees:
		•	an initial license fee of Cdn$10,000 payable in two installments: Cdn$5,000 upon execution of the agreement (paid) and Cdn$5,000 within thirty days of September 2, 2009 (paid);
		•	a further license fee of Cdn$15,000 (paid) to be paid within ninety days of September 2, 2009; and
		•	an annual license fee, payable annually on the anniversary of the date of the agreement as follows:

		1-Sep-12	Cdn$30,000 (accrued)
		1-Sep-13	Cdn$40,000 (accrued)
		September 1, 2014 and each	Cdn$50,000
		successive anniversary
	The Company is to pay the licensor a royalty calculated as 2% of the gross revenue and 15% of any and all consideration directly or indirectly received by the Company from the grant of any sublicense rights. The Company will pay interest at a rate of 1% per month on any amounts past due. In addition, the Company is responsible for the timely payment of all future costs relating to patent expenses and any new or useful art, process, machine, manufacture or composition of matter arising out of any licensor improvements or joint improvements licensed under this agreement and identified by the licensor as potentially patentable. The Company must also invest a minimum of Cdn$250,000 in research and development directly associated with the technology.
		(b)	On May 23, 2012, a former employee of the Company delivered a Notice of Application seeking judgment against the Company for approximately $55,000. The hearing of that Application took place on July 31, 2012, at which time the former employee obtained judgment in the approximate amount of $55,000. The Company did not defend the amount of the judgment and the amount is included in accounts payable, but claims a complete set-off on the basis that the former employee retains 1,000,000 shares of common stock of the Company as security for payment of the outstanding consulting fees owed to him. On August 31, 2012, the Company commenced a separate action against the former employee seeking a return of the 1,000,000 shares of common stock and a stay of execution of the judgment. That application is pending and has not yet been heard or determined by the court. The payment of the judgment claim of approximately $55,000 is dependent upon whether the former employee will first return the 1,000,000 shares of common stock noted above. The probable outcome of the Company’s claim for the return of the shares cannot yet be determined.
		(c)	On March 13, 2013, the Company entered into an agreement with a consultant who will complete a specified project for approximately $137,000 over a period of approximately 15 weeks.

In addition, the Company will grant to each employee 100,000 stock options exercisable at a price of $0.10 per share. These options will be non-transferrable, vest immediately, and expire upon the earlier of 24 months, or upon termination of the employment agreements. The agreements will be immediately terminated if the subsidiary does not receive the NSERC grant.
		(e)	On March 1, 2014, the Company entered into an agreement with a consultant who will perform services for $7,250 a month for a period of one year.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	31-May-14
Basis of Presentation/Principles of Consolidation [Policy Text Block]	'
		(a)	Basis of Presentation/Principles of Consolidation
			These consolidated financial statements and related notes are presented in accordance with accounting principles generally accepted in the United States. These consolidated financial statements include the accounts of the Company and its subsidiaries, Carbon Commodity Corporation, Climate ESCO Ltd., Mantra Energy Alternatives Ltd., Mantra China Inc., Mantra China Limited, Mantra Media Corp., Mantra NextGen Power Inc., and Mantra Wind Inc. All the subsidiaries are wholly-owned with the exception of Climate ESCO Ltd., which is 64.84% owned and Mantra Energy Alternatives Ltd., which is 89.09% owned. All inter- company balances and transactions have been eliminated.
Use of Estimates [Policy Text Block]	'
		(b)	Use of Estimates
			The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company regularly evaluates estimates and assumptions related to allowance for doubtful accounts, the estimated useful lives and recoverability of long-lived assets, valuation of inventory, equity component of convertible debt, stock-based compensation, and deferred income tax asset valuation allowances. The Company bases its estimates and assumptions on current facts, historical experience and various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the accrual of costs and expenses that are not readily apparent from other sources. The actual results experienced by the Company may differ materially and adversely from the Company’s estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected.
Cash and Cash Equivalents [Policy Text Block]	'
		(c)	Cash and Cash Equivalents
			The Company considers all highly liquid instruments with maturity of three months or less at the time of issuance to be cash equivalents.
Accounts Receivable [Policy Text Block]	'
		(d)	Accounts Receivable
			The Company recognizes allowances for doubtful accounts to ensure accounts receivable are not overstated due to the inability or unwillingness of its customers to make required payments. The allowance is based on historical bad debt expense, the age of receivable and the specific identification of receivables the Company considers at risk.
Property and Equipment [Policy Text Block]	'
		(e)	Property and Equipment
			Property and equipment are stated at cost. The Company depreciates the cost of property and equipment over their estimated useful lives at the following annual rates:
		Automotive	3 years straight-line basis
		Computer equipment	3 years straight-line basis
		Leasehold improvements	5 years straight-line basis
		Office equipment and furniture	5 years straight-line basis
		Research equipment	5 years straight-line basis
Intangible Assets [Policy Text Block]	'
		(f)	Intangible Assets
			Intangible assets consist of patents and are stated at cost and have a definite life. Intangible assets are amortized over their estimated useful lives. The Company periodically evaluates the reasonableness of the useful lives of these assets. Once these assets are fully amortized, they are removed from the accounts. These assets are reviewed for impairment or obsolescence when events or changes in circumstances indicate that the carrying amount may not be recoverable. If impaired, intangible assets are written down to fair value based on discounted cash flows or other valuation techniques. The Company has no intangibles with indefinite lives.
Long-lived Assets [Policy Text Block]	'
		(g)	Long-lived Assets
			In accordance with ASC 360, “ Property, Plant and Equipment ”, the Company tests long-lived assets or asset groups for recoverability when events or changes in circumstances indicate that their carrying amount may not be recoverable. Circumstances which could trigger a review include, but are not limited to: significant decreases in the market price of the asset; significant adverse changes in the business climate or legal factors; accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of the asset; current period cash flow or operating losses combined with a history of losses or a forecast of continuing losses associated with the use of the asset; and current expectation that the asset will more likely than not be sold or disposed significantly before the end of its estimated useful life. Recoverability is assessed based on the carrying amount of the asset and its fair value, which is generally determined based on the sum of the undiscounted cash flows expected to result from the use and the eventual disposal of the asset, as well as specific appraisal in certain instances. An impairment loss is recognized when the carrying amount is not recoverable and exceeds fair value.
Foreign Currency Translation [Policy Text Block]	'
		(h)	Foreign Currency Translation
			Transactions in foreign currencies are translated into the currency of measurement at the exchange rates in effect on the transaction date. Monetary balance sheet items expressed in foreign currencies are translated into U.S. dollars at the exchange rates in effect at the balance sheet date. The resulting exchange gains and losses are recognized in income.
			The Company’s integrated foreign subsidiaries are financially or operationally dependent on the Company. The Company uses the temporal method to translate the accounts of its integrated operations into U.S. dollars. Monetary assets and liabilities are translated at the exchange rates in effect at the balance sheet date. Non-monetary assets and liabilities are translated at historical rates. Revenues and expenses are translated at average rates for the period, except for amortization, which is translated on the same basis as the related asset. The resulting exchange gains or losses are recognized in income.
Income Taxes [Policy Text Block]	'
		(i)	Income Taxes
			The Company accounts for income taxes using the asset and liability method in accordance with ASC 740, “ Accounting for Income Taxes ”. The asset and liability method provides that deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized.
			As of May 31, 2014 and 2013, the Company did not have any amounts recorded pertaining to uncertain tax positions.
			The Company files federal and provincial income tax returns in Canada and federal, state and local income tax returns in the U.S., as applicable. The Company may be subject to a reassessment of federal and provincial income taxes by Canadian tax authorities for a period of three years from the date of the original notice of assessment in respect of any particular taxation year. For Canadian and U.S. income tax returns, the open taxation years range from 2010 to 2014. In certain circumstances, the U.S. federal statute of limitations can reach beyond the standard three year period. U.S. state statutes of limitations for income tax assessment vary from state to state. Tax authorities of Canada and U.S. have not audited any of the Company’s, or its subsidiaries’, income tax returns for the open taxation years noted above.
			The Company recognizes interest and penalties related to uncertain tax positions in tax expense. During the years ended May 31, 2014 and 2013, there were no charges for interest or penalties.
Technology Development Revenue [Policy Text Block]	'
		(j)	Technology Development Revenue Recognition
			The Company performs research and development services. The Company recognizes revenue under research contracts when a contract has been executed, the contract price is fixed and determinable, delivery of services or products has occurred, and collectability of the contract price is considered reasonably assured and can be reasonably estimated. Revenue is based on direct labor hours expended at contract billing rates plus other billable direct costs.
Financial Instruments and Fair Value Measures [Policy Text Block]	'
		(k)	Financial Instruments and Fair Value Measures
			ASC 820, “ Fair Value Measurements and Disclosures ” requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. ASC 820 prioritizes the inputs into three levels that may be used to measure fair value:
	Level 1
	Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.
	Level 2
	Level 2 applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.
	Level 3
	Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.
	The Company’s financial instruments consist principally of cash, amounts receivable, accounts payable and accrued liabilities, loans payable, convertible debentures, obligations under capital lease, and amounts due to related parties. Pursuant to ASC 820, the fair value of cash is determined based on “Level 1” inputs, which consist of quoted prices in active markets for identical assets. The recorded values of all other financial instruments approximate their current fair values because of their nature and respective maturity dates or durations.
Research and Development Costs [Policy Text Block]	'
		(l)	Research and Development Costs
			Research and development costs are expensed as incurred.
Stock-based Compensation [Policy Text Block]	'
		(m)	Stock-based Compensation
			The Company records stock-based compensation in accordance with ASC 718, “ Compensation – Stock Compensation ”, using the fair value method. All transactions in which goods or services are the consideration received for the issuance of equity instruments are accounted for based on the fair value of the consideration received or the fair value of the equity instrument issued, whichever is more reliably measurable.
			The Company uses the Black-Scholes option pricing model to calculate the fair value of stock-based awards. This model is affected by the Company’s stock price as well as assumptions regarding a number of subjective variables. These subjective variables include, but are not limited to the Company’s expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors. The value of the portion of the award that is ultimately expected to vest is recognized as an expense in the consolidated statement of operations over the requisite service period.
Loss Per Share [Policy Text Block]	'
		(n)	Loss Per Share
			The Company computes loss per share in accordance with ASC 260, " Earnings per Share " which requires presentation of both basic and diluted earnings per share (“EPS”) on the face of the income statement. Basic EPS is computed by dividing the loss available to common shareholders (numerator) by the weighted average number of shares outstanding (denominator) during the period. Diluted EPS gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method and convertible preferred stock using the if-converted method. In computing diluted EPS, the average stock price for the period is used in determining the number of shares assumed to be purchased from the exercise of stock options or warrants. Diluted EPS excludes all dilutive potential shares if their effect is anti dilutive. As at May 31, 2014, the Company had 10,904,755 (2013 – 10,329,619) dilutive potential shares outstanding.
Comprehensive Loss [Policy Text Block]	'
		(o)	Comprehensive Loss
			ASC 220, “ Comprehensive Income ,” establishes standards for the reporting and display of comprehensive loss and its components in the financial statements. As at May 31, 2014 and 2013, the Company has no items that represent a comprehensive loss and, therefore, has not included a schedule of comprehensive loss in the consolidated financial statements.
Recent Accounting Pronouncements [Policy Text Block]	'
		(p)	Recent Accounting Pronouncements
			The Company has limited operations and is considered to be in the development stage. In the year ended May 31, 2014, the Company has elected to early adopt Accounting Standards Update No. 2014-10,
			Development Stage Entities (Topic 915): Elimination of Certain Financial Reporting Requirements . The adoption of this ASU allows the Company to remove the inception to date information and all references to development stage.
			We do not expect the adoption of any other recently issued accounting pronouncements to have a significant impact on our results of operations, financial position or cash flow.
