SUMMARY_OF_SIGNIFICANT_ACCOUNT

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2014
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Text Block]	NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	The following are summarized accounting policies considered to be significant by the Company’s management:
	Accounting Method
	The Company’s consolidated financial statements are prepared using the accrual basis of accounting in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and have been consistently applied in the preparation of the consolidated financial statements.
	Use of Estimates
	The preparation of consolidated financial statements in accordance with generally accepted accounting principles requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities known to exist as of the date the consolidated financial statements are published, and the reported amounts of revenues and expenses during the reporting period. Uncertainties with respect to such estimates and assumptions are inherent in the preparation of the Company’s consolidated financial statements; accordingly, it is possible that the actual results could differ from these estimates and assumptions and could have a material effect on the reported amounts of the Company’s consolidated financial position and consolidated results of operations.
	Cash and Cash Equivalents
	The Company considers all unrestricted cash, short-term deposits, and other investments with original maturities of no more than ninety days when acquired to be cash and cash equivalents for the purposes of the statement of cash flows. Under the Loan Guarantee Agreement at Neal Hot Springs with the Department of Energy, all funds for USG Oregon LLC are deposited into PNC Bank subject to certain procedural restrictions on the use of the funds. The waterfall of funds out of the Revenue account is processed semi-annually. At December 31, 2014, $3.8 million in USG Oregon LLC funds were deposited at PNC Bank in the Revenue account and $271,000 in Oregon USG Holdings LLC funds were deposited at Umpqua Bank, and were unavailable for immediate corporate needs. Discussion regarding restricted cash is included in Note 3.
	Accounts Receivable Allowance for Doubtful Accounts
	Trade Accounts Receivable Management estimates the amount of trade accounts receivable that may not be collectible and records an allowance for doubtful accounts. The allowance is an estimate based upon aging of receivable balances, historical collection experience, and the periodic credit evaluations of our customers’ financial condition. Receivable balances are written off when we determine that the balance is uncollectible. As of December 31, 2014 and 2013, there were no balances that were over 90 days past due and no balance in allowance for doubtful accounts was recognized.
	Grant Accounts Receivable For receivables from grants from Federal or State agencies, the Company records the receivable amounts net of the funds expected to be received. Therefore, no allowance accounts are considered to be necessary for receivables from grants at December 31, 2014 and 2013.
	Concentration of Credit Risk
	The Company’s cash and cash equivalents, including restricted cash, consisted of commercial bank deposits, money market accounts, and petty cash. Cash deposits are held in commercial banks in Boise, Idaho and Portland, Oregon. Deposits are guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 per legal entity. At December 31, 2014, the Company’s total cash balance, excluding money market funds, was $4,487,085, and bank deposits amounted to $4,577,004. The primary difference was due to outstanding checks and deposits. Of the bank deposits, $3,156,637 was not covered by or was in excess of FDIC insurance guaranteed limits. At December 31, 2014, the Company’s money market funds invested, primarily, in government backed securities totaled $30,515,067 and were not subject to deposit insurance.
	Equity Securities
	The Company determines the appropriate classification of marketable securities at the time of purchase and reevaluates this designation as of each balance sheet date. The Company classifies these securities as either held-to-maturity, trading, or available-for-sale. All marketable securities and restricted investments were classified as available-for-sale securities. The Company classifies its investments as “available for sale” because it does not intend to actively buy and sell for short-term profits. The Company's investments are subject to market risk, primarily interest rate and credit risk. The fair value of investments is determined using observable or quoted market prices for those securities.
	Available-for-sale securities are carried at fair value, with unrealized gains and losses included as a component of accumulated other comprehensive income (loss). Realized gains and losses, declines in value judged to be other than temporary and interest on available-for-sale securities are included in net income. The cost of securities sold is based on the specific identification method whereby the gain or loss is calculated based upon the cost of specifically identified securities for each sales transaction.
	Property, Plant and Equipment
	Property, plant and equipment, including assets under capital lease, are recorded at historical cost. Costs of acquisition of geothermal properties are capitalized in the period of acquisition. Major improvements that significantly increase the useful lives and/or capabilities of the assets are capitalized. A primary factor in determining whether to capitalize construction type costs is the stage of the potential project’s development. Once a project is determined to be commercially viable, all costs directly associated with the development and construction of the project are capitalized. Until that time, all development costs are expensed. A commercially viable project will have, among other factors, a reservoir discovery well or other significant geothermal surface anomaly, a power transmission path that is identified and available, and an electricity off-taker identified. A valid reservoir discovery is generally defined when a test well has been substantially completed that indicates the presence of a geothermal reservoir that has a high probability of possessing the necessary temperatures, permeability, and flow rates. After a valid discovery has been made, the project enters the development stage. Generally, all costs incurred during the development stage are capitalized and tracked on an individual project basis. If a geothermal project is abandoned, the associated costs that have been capitalized are charged to expense in the year of abandonment. Expenditures for repairs and maintenance are charged to expense as incurred. Interest costs incurred during the construction period of defined major projects from debt that is specifically incurred for those projects are capitalized. Funds received from grants associated with capital projects reduce the cost of the asset directly associated with the individual grants. The offset of the cost of the asset associated with grant proceeds is recorded in the period when the requirements of the grant are substantially complete and the amount can be reasonably estimated.
	Direct labor costs, incurred for specific major projects expected to have long-term benefits will be capitalized. Direct labor costs subject to capitalization include employee salaries, as well as, related payroll taxes and benefits. With respect to the allocation of salaries to projects, salaries are allocated based on the percentage of hours that our key managers, engineers and scientists work on each project and are invoiced to the project each month. These individuals track their time worked at each project. Major projects are, generally, defined as projects expected to exceed $500,000. Direct labor includes all of the time incurred by employees directly involved with construction and development activities. General and/or indirect management time and time spent evaluating the feasibility of potential projects is expensed when incurred. Employee training time is expensed when incurred.
	Depreciation is calculated on a straight-line basis over the estimated useful life of the asset. Where appropriate, terms of property rights and revenue contracts can influence the determination of estimated useful lives. Estimated useful lives in years by major asset categories are summarized as follows:
			Estimated Useful
	Asset Categories		Lives in Years
	Furniture, vehicle and other equipment		3 to 5
	Power plant, buildings and improvements		3 to 30
	Wells		30
	Well pumps and components		5 to 15
	Pipelines		30
	Transmission lines		30
	Intangible Assets
	All costs directly associated with the acquisition of geothermal and surface water rights are capitalized as intangible assets. These costs are amortized over their estimated utilization period. There are several factors that influence the estimated utilization periods as well as underlying fair value that include, but are not limited to, the following:
	-	contractual expiration terms of the right,
	-	contractual terms of an associated revenue contract (i.e., PPAs),
	-	compliance with utilization and other requirements, and
	-	hierarchy of other right holders who share the same resource.
	Currently, amortization expense is being calculated on a straight-line basis over an estimated utilization period of 30 years for assets placed in service. If an intangible water or geothermal right is forfeited or otherwise lost, the remaining unamortized costs are expensed in the period of forfeiture. An impaired right is reduced to its estimated fair market value in the year the impairment is realized. Costs incurred that extend the term of an intangible right are capitalized and amortized over the new estimated period of utilization.
	Impairment of Long-Lived Assets
	The Company evaluates its long-term assets annually for impairment and when circumstances/events occur that may impact the fair value of the assets. An impairment loss would be recognized if the carrying amount of a capitalized asset is not recoverable and exceeds its fair value. The most recent assessment was performed based upon financial conditions and assumptions as of December 31, 2014, and there have not been any significant changes in financial conditions and assumptions subsequent to that assessment date. Management believes that there have not been any circumstances that have warranted the recognition of losses due to the impairment of long-lived assets.
	Stock Options Granted to Employees and Non-employees
	The Company follows financial accounting standards that require the measurement of the value of employee services received in exchange for an award of an equity instrument based on the grant-date fair value of the award. For employees, directors and officers, the fair value of the awards are expensed over the vesting period. The current vesting period for all such options is eighteen months.
	Non-employee stock-based compensation is granted at the Board of Director’s discretion to reward select consultants for exceptional performance. Prior to issuance of the awards, the Company was not under any obligation to issue the stock options. Subsequent to the award, the recipient was not obligated to perform any services. Therefore, the fair value of these options was expensed on the grant date, which was also the measurement date.
	Under the fair value recognition provisions, share-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the vesting period. Determining the fair value of share-based awards at the grant date requires judgment. In addition, judgment is also required in estimating the amount of share-based awards that are expected to be forfeited. If actual results differ significantly from these estimates, stock-based compensation expense and our results of operations could be materially impacted.
	Stock Based Compensation Granted to Employees
	The Company recognizes the value of common stock granted to employees and directors over the periods in which the services are received. The value of those services is based upon the estimated fair value of the common stock to be awarded. Estimated fair value is adjusted each reporting period. At the end of each vesting period, estimated fair value is adjusted to fair market value. The adjustment is reflected in the reporting period in which the vesting occurs.
	Earnings Per Share
	The Company follows financial accounting standards, which provides for calculation of "basic" and "diluted" earnings per share. Basic earnings per share includes no dilution and is computed by dividing net income available to common shareholders by the weighted average common shares outstanding for the period. Diluted earnings per share reflect the potential dilution of securities that could share in the earnings of an entity similar to fully diluted earnings per share. Both basic and diluted were presented for the calculation of the income per share for the periods that reported income. Stock equivalents were not included in the calculation for the periods that reported losses since their inclusion would be considered anti-dilutive. Total common stock equivalents on a fully diluted basis at December 31, 2014 and 2013 were 126,744,104 ( 126,006,172 annual weighted average) and 124,494,963 ( 123,497,883 annual weighted average); respectively.
	Financial Instruments
	The Company’s financial instruments consist of cash and cash equivalents, trade account and other receivables, refundable tax credits, and accounts payable and accrued liabilities. Unless otherwise noted, it is management’s opinion that the Company is not exposed to significant interest, currency or credit risks arising from these financial instruments. The fair values of these financial instruments approximate their carrying values, unless otherwise noted.
	The Company’s functional currency is the U.S. dollar. Monetary items are converted into U.S. dollars at the rate prevailing at the balance sheet date. Resulting gains and losses are generally included in determining net income for the period in which exchange rates change.
	Revenue
	Revenue Recognition
	Energy Sales The energy sales revenue is recognized when the electrical power generated by the Company’s power plants is delivered to the customer who is reasonably assured to be able to pay under the terms defined by the Power Purchase Agreements (“PPAs”).
	Renewable Energy Credits (“RECs”) Currently, the Company operates three plants that produce renewable energy that creates a right to a REC. The Company earns one REC for each megawatt hour produced from the geothermal power plant. The Company considers the RECs to be an inventory item held for sale, and outputs that are an economic benefit obtained directly through the operation of the plants. The Company does not currently hold any RECs for our own use. Revenues from RECs sales are recognized when the Company has met the terms and conditions of certain energy sales agreements with a financially capable buyer. At Raft River Energy I LLC, each REC is certified by the Western Electric Coordinating Council and sold under a REC Purchase and Sales Agreement to Holy Cross Energy. At San Emidio and Neal Hot Springs, the RECs are owned by our customer and are bundled with energy sales. At all three plants, title for the RECs pass during the same month as energy sales. As a result, costs associated with the sale of RECs are not segregated on the statement of operations.
	Revenue Source
	All of the Company’s operating revenues (energy sales and energy credit sales) originate from energy production from its interests in geothermal power plants located in the states of Idaho, Oregon and Nevada.
	Asset Retirement Obligations
	The Company records the fair value of estimated asset retirement obligations (“AROs”) associated with tangible long-lived assets in the period incurred or acquired. AROs are legal obligations to settle under existing or enacted law, statue, or contract. The value of these obligations are originally based upon discounted cash flow estimates and are accreted to full value over time through charges to operations. Costs associated with future conditions are recognized as AROs in the period the condition occurs or is known to the Company. Generally, costs associated with AROs are earthwork, revegetation, well capping, and structure removal necessary to return the sites to their original conditions.
	Reclassification
	Certain amounts in the prior period financial statements have been reclassified to conform to the current period presentation. These reclassifications had no effect on reported income, total assets, or stockholders’ equity as previously reported.
	Recent Accounting Pronouncements
	Management has considered all recent accounting pronouncements. The following pronouncements were deemed applicable to our financial statements:
	Stock Compensation
	In June 2014, FASB issued Accounting Standards Update No. 2014-12 (“Update 2014-12”), Compensation-Stock Compensation, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (Topic 718). Update 2014-12 provides guidance on how to account for share-based payment awards that require a specific performance target to be achieved in order for the employees to become eligible to vest in the awards. Update 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Management is still evaluating the applicability and possible impact this update may have on the accounting treatment and its financial statement presentation.
	Presentation of Property, Plant and Equipment
	In April 2014, FASB issued Accounting Standards Update No. 2014-08 (“Update 2014-08”), Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360), Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. Update 2014-08 provides guidance to address the issues surrounding the reporting of discontinued operations and enhance the convergence of the FASB’s and the International Accounting Standard Board’s reporting requirements for discontinued operations. Update 2014-08 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Management is still evaluating the applicability and possible impact this update may have on the accounting treatment and its financial statement presentation.
Business Combinations In December 2014, FASB issued Accounting Standards Update No. 2014-18 (“Update 2014-18”), Accounting for Identifiable Intangible Assets in Business Combination, Business Combinations (Topic 805). Update 2014-18 provides modifications to the evaluation of variable interest entities that may impact consolidation of reporting entities. Update 2014-18 is effective for fiscal year beginning after December 15, 2015, and the effective date of adoption depends on the timing of that first in-scope transaction. If the first in-scope transaction occurs in the first fiscal year beginning after December 12, 2015, the elective adoption will be effective for that fiscal year’s annual financial reporting and all interim and annual periods thereafter. The focus of this Update addresses the types of intangible assets that the Company, typically, has not acquired or does not seek to acquire; however, Management will continue to evaluate the possible impact that this Update may have on the accounting treatment of applicable elements and the financial presentation of these elements.
Consolidation In February 2015, FASB issued Accounting Standards Update No. 2015-02 (“Update 2015-02”), Amendments to the Consolidation Analysis, Consolidation (Topic 810). Update 2015-02 provides modifications to the evaluation of variable interest entities that may impact consolidation of reporting entities. Update 2015-02 is effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The Company currently consolidates variable interest entities and may create or acquire variable interest entities for future endeavors. Management is still evaluating the possible impact this update may have on the financial presentation of the Company’s consolidated financial statements.

	During the year ended December, 2014, the Company continued development activities for San Emidio, Nevada and the Guatemala projects. Two new exploration wells for the San Emidio Phase II project were drilled, one exploration well drilled in 2013 was abandoned, and one other well drilled in 2013 was placed into production during the year for approximately $2.03 million. A portion of the drilling and development costs were offset by grant proceeds of $632,210. The new production well was connected to the existing Phase I power plant and is producing fluid to the plant as part of a long term test of the South Zone reservoir. During the year, costs that exceeded $924,000 were incurred at Guatemala for the construction of nine temperature gradient wells.
	On December 12, 2014, the Company completed an acquisition of Earth Power Resources Inc. See Note 16 for details. After acquisition, the Company incurred approximately $133,000 on the drilling of a new production well.
	Effective April 22, 2014, the Company acquired a group of companies (The Geysers, California) that included long-term assets that totaled $7.74 million (land of $1.6 million, well and drilling construction in progress of $6.14 million). See note 16 for acquisition details. After acquisition, the Company incurred development costs of approximately $259,000 for design and study work for a new power plant, transmission line and well field.
	During the year ended December, 2013, the Company determined that the project located in the Republic of Guatemala was economically viable and began capitalizing drilling costs that amounted to over $1.7 million. At Neal Hot Springs, an agreement was reached with a major contractor that resulted in the reduction of project costs and related retainage of $2.26 million. Additional costs of approximately $7.8 million were incurred at the Neal Hot Springs power plant to finalize construction costs. The remaining balance of the ITC cash grant for San Emidio relating to previously disputed expenditures of approximately $1.05 million was collected. On February 15, 2013, the Company signed a settlement agreement with SAIC (the general contractor and construction loan holder) that reduced the construction liability including construction costs and accrued interest by approximately $2.14 million for the San Emidio, Nevada project. Costs that totaled approximately $817,000 were capitalized for a phase II monitoring well at San Emidio.

INCOME_TAXES

INCOME TAXES	12 Months Ended
	Dec. 31, 2014
INCOME TAXES [Text Block]	NOTE 7 – INCOME TAXES
	To produce the estimated income tax assets and liabilities, several estimates are required than include: current and future federal and State income tax rates, State apportionment factors, future earnings, the Company’s tax positions, financial elements/terms used for stock option valuation, and availability of tax credits and other benefits. Federal and State income tax law is constantly changing and is subject to inherent uncertainties due different interpretations and tax positions. Although Management believes that its estimates are reasonable, no assurance can be given that the final tax outcome of these matters will not be different than that which is reflected in our tax provisions. Ultimately, the actual tax benefits to be realized will be based upon future taxable earnings levels, which are very difficult to predict.
	Income taxes are recorded based upon the liability method. Under this approach, deferred income taxes are recorded to reflect the tax consequences in future years of differences between the tax basis of assets and liabilities and their financial reporting amounts at each year-end.
	At December 31, 2014, the Company had net deferred tax assets calculated at an expected rate, noted in the table below, of approximately $12,102,000 (December 31, 2013 - $10,435,000). As of December 31, 2013, the Company recognized the net deferred income tax asset to the extent of the impact on current book earnings. Effective December 31, 2014, Company management believes that historical, current and expected earnings are sufficient to meet the more likely than not standard to enable the Company to recognize the net deferred tax asset. As allowable under accounting standards, the Company elects to fully remove the valuation allowance as of December 31, 2014.
	The Company’s significant temporary timing differences that impact deferred income tax assets and liabilities are stock compensation and book to tax depreciation. The recognition of employee stock compensation has different rules that impact both the value and the timing of recognized compensation costs. Typically, employee stock compensation costs are higher and are recognized before compensation costs are allowable for income tax purposes. The book value of the deferred stock compensation asset, related to stock options, is reduced when the options are exercised, forfeited or expire. Differences in book to tax depreciation costs, generally, result in a deferred tax liability. Allowable depreciation expenses for income tax purposes utilize shorter asset lives and are calculated using accelerated methods (i.e., MACRS). Also, the Company has both earned and acquired NOLs available to offset current and future earnings.
	For financial reporting purposes the Company reports its operations as fully consolidated entity; however, for tax purposes the entities that have multiple ownership interests report their activities as separate entities. Some portions of the tax differences created by the structure of the reporting entities are limited to the consolidated Company as a whole. These differences, calculated with the estimated income tax rate are summarized as follows:
			31-Dec-14
			Consolidated			Adjustments			Net Available
	Deferred tax assets:
	Net operating loss carry forward	$	47,696,000		$	-17,096,000		$	30,600,000
	Stock based compensation		1,518,000			-			1,518,000
	Deferred tax liabilities:

	Net deferred tax asset	$	4,274,000		$	6,033,000		$	10,307,000
	The significant components of the net deferred tax asset calculated with the estimated effective income tax rate were as follows:
				December 31,
				2014			2013
		Current deferred tax assets:
		Net operating loss carry forward	$	1,730,000		$	-
		Stock based compensation		73,000			28,000

		Deferred tax asset recognized and utilized in current period		-1,753,000			-1,578,000
		Deferred tax asset valuation allowance		-			-8,857,000
		Net deferred tax asset	$	10,307,000		$	-
	The current portion of the deferred tax asset is based upon an estimate of the earnings for the year ended December 31, 2015.
	When calculating the effective tax rate, the federal income tax rate was used in addition to the applicable State income tax rates as deductible for federal income taxes. At year end, the Company held interests in the States of Idaho, Oregon, Nevada and California. The calculation of the average State income tax rate was based upon State apportionment factors that included operating revenues, payroll costs, and property costs. The Company, also, has interests in the Republic of Guatemala; however, the income tax effect of these interests were minimal for the years ended December 31, 2014 and 2013.
	The Company’s estimated effective income tax rate is as follows:
				For the Years Ended December 31,
				2014			2013
		U.S. Federal statutory rate		34.00%			34.00%
		Average State and foreign income tax, net of federal tax effect		3.7			4.2
		Production tax credits		-			-
		Net effective tax rate		37.70%			38.20%
	At December 31, 2014, the Company had net income tax operating loss carry forwards of approximately $81,166,000 ($74,550,000 in December 31, 2013), which expire in the years 2023 through 2034. Approximately $76,837,000 of the operating losses were generated by the Company; the residual were acquired. On April 22, 2014, the Company purchased a group of companies (see note 16 for details). Federal and applicable state net operating losses that totalled approximately $30 million were included in the acquisition. These NOLs are scheduled to expire in the years ending 2028 through 2033. The use of these net operating losses is restricted by the Company’s basis and the “applicable federal rate” as defined by Section 382 of federal tax law. The estimated available net operating losses from the acquired companies were approximately $4,329,000 at December 31, 2014.
	The net change in the deferred tax asset valuation allowance account is detailed as follows:
			For the Year Ended December 31,
			2014			2013
	Change in net operating loss	$	5,588,000		$	16,258,000
	Change in estimated effective tax rate		-45,000			614,000

	Net change in deferred tax valuation allowance	$	-8,857,000		$	-1,973,000
	At December 31, 2014, Raft River Energy I LLC has a book-to-tax difference of $38.7 million due to the acceleration of intangible drilling costs and depreciation. By contract, 99% percent of this book-to-tax difference has been allocated to the non-controlling interest and would not be available to the consolidated group to offset future tax liabilities. At December 31, 2014, USG Oregon LLC has a book-to-tax difference of $57.5 million due to the acceleration of depreciation.
	Accounting for Income Tax Uncertainties and Related Matters
	The Company may be assessed penalties and interest related to the underpayment of income taxes. Such assessments would be treated as a provision of income tax expense on the financial statements. For the years ended December 31, 2014 and 2013, and the nine months ended December 31, 2012, no income tax expense has been realized as a result of operations and no income tax penalties and interest have been accrued related to uncertain tax positions. The Company files income tax returns in the U.S. federal jurisdiction and in the States of Idaho, California and Oregon. These filings are subject to a three year statute of limitations. The Company’s evaluation of income tax positions included the year ended December 31, 2014 and 2013, and the nine months ended December 31, 2012. No filings are currently under examination. No adjustments due to tax uncertainties have been made to reduce the estimated income tax benefit at year end. Any valuations relating to these income tax provisions will comply with U.S. Generally Accepted Accounting Principles .

	On August 31, 2011, USG Oregon LLC (“USG Oregon”), a subsidiary of the Company, completed the first funding drawdown associated with the U.S. Department of Energy (“DOE”) $96.8 million loan guarantee (“Loan Guarantee”) to construct its power plant at Neal Hot Springs in Eastern Oregon (the “Project”). The U.S. Treasury’s Federal Financing Bank, as lender for the Project, issues payments direct to vendors. All loan advances covered by the Loan Guarantee have been made under the Future Advance Promissory Note (the “Note”) dated February 23, 2011. Upon the occurrence and continuation of an event of default under the transaction documents, all amounts payable under the Note may be accelerated. In connection with the Loan Guarantee, the DOE has been granted a security interest in all of the equity interests of USG Oregon, as well as in the assets of USG Oregon, including a mortgage on real property interests relating to the Project site. The loan advances began August 31, 2011 and the last advance was taken on July 31, 2013. No additional advances are allowed under the terms of the loan. A total of 13 draws were taken and each individual draw or tranche is considered to be a separate loan. On August 12, 2013, proceeds of the ITC cash grant were distributed in accordance with the loan agreement, with $11,870,137 of the proceeds being used to prepay the Project loan, $11,167,473 of proceeds being used to fund a series of Project reserves, and balance of $9,711,930 being distributed as equity to the project owners. After the loan prepayment, the remaining final loan balance was $70,386,576. The loan principal is scheduled to be paid over 21.5 years with semi-annual installments including interest calculated at an aggregate fixed interest rate of 2.598% . The principal payment amounts are calculated on a straight-line basis according to the life of the loans and the original loan principal amounts. The principal portion of the aggregate loan payment is adjusted as individual tranches are extinguished. The principal payments are scheduled to start at $1,709,963 and are expected to be reduced to $1,626,251 on February 10, 2017. The loan balance at December 31, 2014 totaled $66,974,610 (estimated current portion $3,419,927).

	The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model using the assumptions noted in the following table. Expected volatilities are based on historical volatility of the Company’s stock. The Company uses historical data to estimate option volatility within the Black-Scholes model. The expected term of options granted represents the period of time that options granted are expected to be outstanding, based upon past experience and future estimates and includes data from the Plan. The risk-free rate for periods within the expected term of the option is based upon the U.S. Treasury yield curve in effect at the time of grant. The Company currently does not foresee the payment of dividends in the near term.
	The fair value of the stock options granted was estimated using the Black-Scholes option-pricing model and is amortized over the vesting period of the underlying options. The assumptions used to calculate the fair value are as follows:
				For the Year Ended December 31,
				2014			2013
		Dividend yield		0			0
		Expected volatility		81 - 100%			71 - 81%
		Risk free interest rate		0.69 - 0.82%			0.27 - 0.82%
		Expected life (years)		2.94			4.63
	Changes in the subjective input assumptions can materially affect the fair value estimate and, therefore, the existing models do not necessarily provide a reliable measure of the fair value of the Company’s stock options.

FAIR_VALUE_MEASUREMENT

FAIR VALUE MEASUREMENT	12 Months Ended
	Dec. 31, 2014
FAIR VALUE MEASUREMENT [Text Block]	NOTE 12 – FAIR VALUE MEASUREMENT
	Current U.S. generally accepted accounting principles establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement).
	The three levels of the fair value hierarchy are as follows:
	Level 1 – Quoted prices are available in active markets for identical assets or liabilities. Active markets are those in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
	Level 2 – Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors, and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace.
	Level 3 – Pricing inputs include significant inputs that are generally unobservable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value. Level 3 instruments include those that may be more structured or otherwise tailored to the Company’s needs.
	Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.
	The following table discloses by level within the fair value hierarchy the Company’s assets and liabilities measured and reported on its Consolidated Balance Sheet as of December 31, 2014 at fair value on a recurring basis:
			Total		Level 1		Level 2		Level 3
	Assets:
	Money market accounts *	$	30,515,067	$	30,515,067	$	-	$	-
	* - Money market accounts include both restricted and unrestricted funds.
	As allowed by current financial reporting standards, the Company has elected not to implement fair value recognition and reporting for all non-financial assets and non-financial liabilities, except for those that are recognized or disclosed at fair value in the financial statements on a recurring basis, that is, at least annually.

	Operating Lease Agreements
	The Company has entered into several lease agreements with terms expiring up to December 1, 2034 for geothermal properties in Neal Hot Springs, Oregon; Washoe County, Nevada; Eureka County, Nevada; The Geysers, California; Raft River, Idaho and the Republic of Guatemala. The Company incurred total lease expenses for the years ended December 31, 2014 and 2013, of $579,815 and $286,923 ; respectively. The Company believes that it is in compliance with all of the following lease terms.
	BLM Lease Agreements
	Idaho
	On August 1, 2007, the Company signed a geothermal resources lease agreement with the United States Department of the Interior Bureau of Land Management (“BLM”). The contract requires an annual payment of $3,502 including processing fees. The primary term of the agreement is 10 years. After the primary term, the Company has the right to extend the contract. BLM has the right to terminate the contract upon written notice if the Company does not comply with the terms of the agreement.
	San Emidio
	The lease contracts are for approximately 21,905 acres of land and geothermal rights located in the San Emidio Desert, Nevada. The lease contracts have primary terms of 10 years. Per federal regulations applicable for the contracts, the lessee has the option to extend the primary lease term another 40 years if the BLM does not need the land for any other purpose and the lessee is maintaining production at commercial quantities. The leases require the lessee to conduct operations in a manner that minimizes adverse impacts to the environment.
	Gerlach
	The Gerlach Geothermal LLC assets are comprised of two BLM geothermal leases and one private lease totaling 3,615 acres. Both BLM leases have a royalty rate which is based upon 10% of the value of the resource at the wellhead. The amounts are calculated according to a formula established by Minerals Management Service (“MMS”). One of the two BLM leases has a second royalty commitment to a third party of 4% of gross revenue for power generation and 5% for direct use based on BTUs consumed at a set comparable price of $7.00 per million BTU of natural gas. The private lease has a 10 year primary term and would receive a royalty of 3% gross revenue for the first 10 years and 4% thereafter.

	Power Purchase Agreements
	Raft River Energy I LLC
	The Company signed a power purchase agreement with Idaho Power Company for the sale of power generated from its joint venture Raft River Energy I LLC. The Company also signed a transmission agreement with Bonneville Power Administration for transmission of electricity from this plant to Idaho Power. These agreements will govern the operational revenues for the initial phases of the Company’s operating activities. The contract allows power sales up to 13 megawatts annual average. The price of energy sold under the Idaho Power PPA is split into three seasons: power produced during the peak periods of July, August, November and December will be purchased at 120% of the set price; power produced in the three month low demand season (March, April, May) will be purchased at 73.50% of the set price; and power produced in the remaining five months of the year will be purchased at 100% of the set price. The PPA sets a first year average purchase price of $53.60 per megawatt hour. The $53.60 purchase price is escalated each year at a compound annual rate of 2.1% until year 15. From years 16 to 25 of the contract the escalation rate will drop to 0.6% per year.
	USG Nevada LLC
	As a part of the purchase of the assets from Empire Geothermal Power, LLC and Michael B. Stewart acquisition (“Empire Acquisition”), a power purchase agreement with Sierra Pacific Power Company was assigned to the Company. The contract had a stated expected output of 3,250 kilowatts maximum per hour and extended through 2017. During the year ended March 31, 2012, the power purchase agreement was replaced by a new amended and restated 25 year contract signed in December of 2011 that sets the new rate at $89.75 per megawatt hour with a 1% annual escalation rate. The new contract currently allows for a maximum of 73,444 megawatt hours annually that will be paid for at the full contract price. Upon declaration of commercial operation under the PPA, an Operating Security Deposit is required to be maintained at NV Energy for the full term of the PPA. As of December 31, 2014, the Company has funded a security deposit of $1,468,898.
	USG Oregon LLC
	In December of 2009, the Company’s subsidiary (USG Oregon LLC), signed a power purchase agreement with Idaho Power Company for the sale of power generated by the Neal Hot Springs, Oregon project. The agreement has a term of 25 years and provides for the purchase of power up to 25 megawatts (22 megawatt planned annual average output level). Beginning 2012, the flat energy price is $96.00 per megawatt hour. The price escalates annually by 3.9% in the initial years and by 1.0% during the latter years of the agreement. The approximate 25 -year levelized price is $117.65 per megawatt hour.
	Asset Retirement Obligations (“AROs”)
	The Geysers, California
	On April 22, 2014, the Company completed the acquisition of a group of companies owned by Ram Power Corp.’s (“Ram”) Geysers Project located in Northern California. Two of the acquired companies (Western GeoPower, Inc. and Etoile Holdings, Inc.) contained asset retirement obligations that, primarily, originate with the environmental regulations defined by the laws of the State of California. The liabilities related to the removal and disposal of arsenic impacted soil and existing steam conveyance pipelines are estimated to total $800,000. Obligations related to decommissioning four existing wells were estimated to total $600,000. These obligations are based upon the expected future value of the remedy or settlement and the values have not been calculated at discounted rates. At December 31, 2014, the Company has not considered it necessary to specifically fund these obligations. Since management is still evaluating the development plan for this project that could eliminate or significantly reduce these obligations, no charges directly associated the asset retirement obligations have been charged to operations. All of the obligations are considered to be long-term at December 31, 2014.
	Raft River Energy I LLC, USG Nevada LLC, and USG Oregon LLC
	These Companies operate in Idaho, Nevada and Oregon and are subject to environmental laws and regulations of these states. The plants, wells, pipelines and transmission lines are expected to have long useful lives. Generally, these assets will require funds for retirement or reclamation. However, these estimated obligations are believed to be less than or not significantly more than the assets’ estimated salvage values. Therefore, as of December 31, 2014, no retirement obligations have been recognized.
	401(k) Plan
	The Company offers a defined contribution plan qualified under section 401(k) of the Internal Revenue Code to all its eligible employees. All employees are eligible at the beginning of the quarter after completing 3 months of service. Subsequent to June 30, 2013, the Company began matching 50% of the employee’s contribution up to 6%. Prior to June 30, 2013, the plan required the Company to match 25% of the employee’s contribution up to 6%. Employees may contribute up to the maximum allowed by the Internal Revenue Code. The Company made matching contributions to the plan that totaled $97,785 and $60,425 for the years ended December 31, 2014 and 2013, respectively.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Method [Policy Text Block]	Accounting Method
	The Company’s consolidated financial statements are prepared using the accrual basis of accounting in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and have been consistently applied in the preparation of the consolidated financial statements.
Use of Estimates [Policy Text Block]	Use of Estimates
	The preparation of consolidated financial statements in accordance with generally accepted accounting principles requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities known to exist as of the date the consolidated financial statements are published, and the reported amounts of revenues and expenses during the reporting period. Uncertainties with respect to such estimates and assumptions are inherent in the preparation of the Company’s consolidated financial statements; accordingly, it is possible that the actual results could differ from these estimates and assumptions and could have a material effect on the reported amounts of the Company’s consolidated financial position and consolidated results of operations.
Cash and Cash Equivalents [Policy Text Block]	Cash and Cash Equivalents
	The Company considers all unrestricted cash, short-term deposits, and other investments with original maturities of no more than ninety days when acquired to be cash and cash equivalents for the purposes of the statement of cash flows. Under the Loan Guarantee Agreement at Neal Hot Springs with the Department of Energy, all funds for USG Oregon LLC are deposited into PNC Bank subject to certain procedural restrictions on the use of the funds. The waterfall of funds out of the Revenue account is processed semi-annually. At December 31, 2014, $3.8 million in USG Oregon LLC funds were deposited at PNC Bank in the Revenue account and $271,000 in Oregon USG Holdings LLC funds were deposited at Umpqua Bank, and were unavailable for immediate corporate needs. Discussion regarding restricted cash is included in Note 3.
Accounts Receivable Allowance for Doubtful Accounts [Policy Text Block]	Accounts Receivable Allowance for Doubtful Accounts
	Trade Accounts Receivable Management estimates the amount of trade accounts receivable that may not be collectible and records an allowance for doubtful accounts. The allowance is an estimate based upon aging of receivable balances, historical collection experience, and the periodic credit evaluations of our customers’ financial condition. Receivable balances are written off when we determine that the balance is uncollectible. As of December 31, 2014 and 2013, there were no balances that were over 90 days past due and no balance in allowance for doubtful accounts was recognized.
	Grant Accounts Receivable For receivables from grants from Federal or State agencies, the Company records the receivable amounts net of the funds expected to be received. Therefore, no allowance accounts are considered to be necessary for receivables from grants at December 31, 2014 and 2013.
Concentration of Credit Risk [Policy Text Block]	Concentration of Credit Risk
	The Company’s cash and cash equivalents, including restricted cash, consisted of commercial bank deposits, money market accounts, and petty cash. Cash deposits are held in commercial banks in Boise, Idaho and Portland, Oregon. Deposits are guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 per legal entity. At December 31, 2014, the Company’s total cash balance, excluding money market funds, was $4,487,085, and bank deposits amounted to $4,577,004. The primary difference was due to outstanding checks and deposits. Of the bank deposits, $3,156,637 was not covered by or was in excess of FDIC insurance guaranteed limits. At December 31, 2014, the Company’s money market funds invested, primarily, in government backed securities totaled $30,515,067 and were not subject to deposit insurance.
Equity Securities [Policy Text Block]	Equity Securities
	The Company determines the appropriate classification of marketable securities at the time of purchase and reevaluates this designation as of each balance sheet date. The Company classifies these securities as either held-to-maturity, trading, or available-for-sale. All marketable securities and restricted investments were classified as available-for-sale securities. The Company classifies its investments as “available for sale” because it does not intend to actively buy and sell for short-term profits. The Company's investments are subject to market risk, primarily interest rate and credit risk. The fair value of investments is determined using observable or quoted market prices for those securities.
	Available-for-sale securities are carried at fair value, with unrealized gains and losses included as a component of accumulated other comprehensive income (loss). Realized gains and losses, declines in value judged to be other than temporary and interest on available-for-sale securities are included in net income. The cost of securities sold is based on the specific identification method whereby the gain or loss is calculated based upon the cost of specifically identified securities for each sales transaction.
Property, Plant and Equipment [Policy Text Block]	Property, Plant and Equipment
	Property, plant and equipment, including assets under capital lease, are recorded at historical cost. Costs of acquisition of geothermal properties are capitalized in the period of acquisition. Major improvements that significantly increase the useful lives and/or capabilities of the assets are capitalized. A primary factor in determining whether to capitalize construction type costs is the stage of the potential project’s development. Once a project is determined to be commercially viable, all costs directly associated with the development and construction of the project are capitalized. Until that time, all development costs are expensed. A commercially viable project will have, among other factors, a reservoir discovery well or other significant geothermal surface anomaly, a power transmission path that is identified and available, and an electricity off-taker identified. A valid reservoir discovery is generally defined when a test well has been substantially completed that indicates the presence of a geothermal reservoir that has a high probability of possessing the necessary temperatures, permeability, and flow rates. After a valid discovery has been made, the project enters the development stage. Generally, all costs incurred during the development stage are capitalized and tracked on an individual project basis. If a geothermal project is abandoned, the associated costs that have been capitalized are charged to expense in the year of abandonment. Expenditures for repairs and maintenance are charged to expense as incurred. Interest costs incurred during the construction period of defined major projects from debt that is specifically incurred for those projects are capitalized. Funds received from grants associated with capital projects reduce the cost of the asset directly associated with the individual grants. The offset of the cost of the asset associated with grant proceeds is recorded in the period when the requirements of the grant are substantially complete and the amount can be reasonably estimated.
	Direct labor costs, incurred for specific major projects expected to have long-term benefits will be capitalized. Direct labor costs subject to capitalization include employee salaries, as well as, related payroll taxes and benefits. With respect to the allocation of salaries to projects, salaries are allocated based on the percentage of hours that our key managers, engineers and scientists work on each project and are invoiced to the project each month. These individuals track their time worked at each project. Major projects are, generally, defined as projects expected to exceed $500,000. Direct labor includes all of the time incurred by employees directly involved with construction and development activities. General and/or indirect management time and time spent evaluating the feasibility of potential projects is expensed when incurred. Employee training time is expensed when incurred.
	Depreciation is calculated on a straight-line basis over the estimated useful life of the asset. Where appropriate, terms of property rights and revenue contracts can influence the determination of estimated useful lives. Estimated useful lives in years by major asset categories are summarized as follows:
			Estimated Useful
	Asset Categories		Lives in Years
	Furniture, vehicle and other equipment		3 to 5
	Power plant, buildings and improvements		3 to 30
	Wells		30
	Well pumps and components		5 to 15
	Pipelines		30
	Transmission lines		30
Intangible Assets [Policy Text Block]	Intangible Assets
	All costs directly associated with the acquisition of geothermal and surface water rights are capitalized as intangible assets. These costs are amortized over their estimated utilization period. There are several factors that influence the estimated utilization periods as well as underlying fair value that include, but are not limited to, the following:
	-	contractual expiration terms of the right,
	-	contractual terms of an associated revenue contract (i.e., PPAs),
	-	compliance with utilization and other requirements, and
	-	hierarchy of other right holders who share the same resource.
	Currently, amortization expense is being calculated on a straight-line basis over an estimated utilization period of 30 years for assets placed in service. If an intangible water or geothermal right is forfeited or otherwise lost, the remaining unamortized costs are expensed in the period of forfeiture. An impaired right is reduced to its estimated fair market value in the year the impairment is realized. Costs incurred that extend the term of an intangible right are capitalized and amortized over the new estimated period of utilization.
Impairment of Long-Lived Assets [Policy Text Block]	Impairment of Long-Lived Assets
	The Company evaluates its long-term assets annually for impairment and when circumstances/events occur that may impact the fair value of the assets. An impairment loss would be recognized if the carrying amount of a capitalized asset is not recoverable and exceeds its fair value. The most recent assessment was performed based upon financial conditions and assumptions as of December 31, 2014, and there have not been any significant changes in financial conditions and assumptions subsequent to that assessment date. Management believes that there have not been any circumstances that have warranted the recognition of losses due to the impairment of long-lived assets.
Stock Options Granted to Employees and Non-employees [Policy Text Block]	Stock Options Granted to Employees and Non-employees
	The Company follows financial accounting standards that require the measurement of the value of employee services received in exchange for an award of an equity instrument based on the grant-date fair value of the award. For employees, directors and officers, the fair value of the awards are expensed over the vesting period. The current vesting period for all such options is eighteen months.
	Non-employee stock-based compensation is granted at the Board of Director’s discretion to reward select consultants for exceptional performance. Prior to issuance of the awards, the Company was not under any obligation to issue the stock options. Subsequent to the award, the recipient was not obligated to perform any services. Therefore, the fair value of these options was expensed on the grant date, which was also the measurement date.
	Under the fair value recognition provisions, share-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the vesting period. Determining the fair value of share-based awards at the grant date requires judgment. In addition, judgment is also required in estimating the amount of share-based awards that are expected to be forfeited. If actual results differ significantly from these estimates, stock-based compensation expense and our results of operations could be materially impacted.
Stock Based Compensation Granted to Employees [Policy Text Block]	Stock Based Compensation Granted to Employees
	The Company recognizes the value of common stock granted to employees and directors over the periods in which the services are received. The value of those services is based upon the estimated fair value of the common stock to be awarded. Estimated fair value is adjusted each reporting period. At the end of each vesting period, estimated fair value is adjusted to fair market value. The adjustment is reflected in the reporting period in which the vesting occurs.
Earnings Per Share [Policy Text Block]	Earnings Per Share
	The Company follows financial accounting standards, which provides for calculation of "basic" and "diluted" earnings per share. Basic earnings per share includes no dilution and is computed by dividing net income available to common shareholders by the weighted average common shares outstanding for the period. Diluted earnings per share reflect the potential dilution of securities that could share in the earnings of an entity similar to fully diluted earnings per share. Both basic and diluted were presented for the calculation of the income per share for the periods that reported income. Stock equivalents were not included in the calculation for the periods that reported losses since their inclusion would be considered anti-dilutive. Total common stock equivalents on a fully diluted basis at December 31, 2014 and 2013 were 126,744,104 ( 126,006,172 annual weighted average) and 124,494,963 ( 123,497,883 annual weighted average); respectively.
Financial Instruments [Policy Text Block]	Financial Instruments
	The Company’s financial instruments consist of cash and cash equivalents, trade account and other receivables, refundable tax credits, and accounts payable and accrued liabilities. Unless otherwise noted, it is management’s opinion that the Company is not exposed to significant interest, currency or credit risks arising from these financial instruments. The fair values of these financial instruments approximate their carrying values, unless otherwise noted.
	The Company’s functional currency is the U.S. dollar. Monetary items are converted into U.S. dollars at the rate prevailing at the balance sheet date. Resulting gains and losses are generally included in determining net income for the period in which exchange rates change.
Revenue [Policy Text Block]	Revenue
	Revenue Recognition
	Energy Sales The energy sales revenue is recognized when the electrical power generated by the Company’s power plants is delivered to the customer who is reasonably assured to be able to pay under the terms defined by the Power Purchase Agreements (“PPAs”).
	Renewable Energy Credits (“RECs”) Currently, the Company operates three plants that produce renewable energy that creates a right to a REC. The Company earns one REC for each megawatt hour produced from the geothermal power plant. The Company considers the RECs to be an inventory item held for sale, and outputs that are an economic benefit obtained directly through the operation of the plants. The Company does not currently hold any RECs for our own use. Revenues from RECs sales are recognized when the Company has met the terms and conditions of certain energy sales agreements with a financially capable buyer. At Raft River Energy I LLC, each REC is certified by the Western Electric Coordinating Council and sold under a REC Purchase and Sales Agreement to Holy Cross Energy. At San Emidio and Neal Hot Springs, the RECs are owned by our customer and are bundled with energy sales. At all three plants, title for the RECs pass during the same month as energy sales. As a result, costs associated with the sale of RECs are not segregated on the statement of operations.
	Revenue Source
	All of the Company’s operating revenues (energy sales and energy credit sales) originate from energy production from its interests in geothermal power plants located in the states of Idaho, Oregon and Nevada.
Asset Retirement Obligations [Policy Text Block]	Asset Retirement Obligations
	The Company records the fair value of estimated asset retirement obligations (“AROs”) associated with tangible long-lived assets in the period incurred or acquired. AROs are legal obligations to settle under existing or enacted law, statue, or contract. The value of these obligations are originally based upon discounted cash flow estimates and are accreted to full value over time through charges to operations. Costs associated with future conditions are recognized as AROs in the period the condition occurs or is known to the Company. Generally, costs associated with AROs are earthwork, revegetation, well capping, and structure removal necessary to return the sites to their original conditions.
Reclassification [Policy Text Block]	Reclassification
	Certain amounts in the prior period financial statements have been reclassified to conform to the current period presentation. These reclassifications had no effect on reported income, total assets, or stockholders’ equity as previously reported.
Recent Accounting Pronouncements [Policy Text Block]	Recent Accounting Pronouncements
	Management has considered all recent accounting pronouncements. The following pronouncements were deemed applicable to our financial statements:
	Stock Compensation
	In June 2014, FASB issued Accounting Standards Update No. 2014-12 (“Update 2014-12”), Compensation-Stock Compensation, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (Topic 718). Update 2014-12 provides guidance on how to account for share-based payment awards that require a specific performance target to be achieved in order for the employees to become eligible to vest in the awards. Update 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Management is still evaluating the applicability and possible impact this update may have on the accounting treatment and its financial statement presentation.
	Presentation of Property, Plant and Equipment
	In April 2014, FASB issued Accounting Standards Update No. 2014-08 (“Update 2014-08”), Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360), Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. Update 2014-08 provides guidance to address the issues surrounding the reporting of discontinued operations and enhance the convergence of the FASB’s and the International Accounting Standard Board’s reporting requirements for discontinued operations. Update 2014-08 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Management is still evaluating the applicability and possible impact this update may have on the accounting treatment and its financial statement presentation.
	Business Combinations In December 2014, FASB issued Accounting Standards Update No. 2014-18 (“Update 2014-18”), Accounting for Identifiable Intangible Assets in Business Combination, Business Combinations (Topic 805). Update 2014-18 provides modifications to the evaluation of variable interest entities that may impact consolidation of reporting entities. Update 2014-18 is effective for fiscal year beginning after December 15, 2015, and the effective date of adoption depends on the timing of that first in-scope transaction. If the first in-scope transaction occurs in the first fiscal year beginning after December 12, 2015, the elective adoption will be effective for that fiscal year’s annual financial reporting and all interim and annual periods thereafter. The focus of this Update addresses the types of intangible assets that the Company, typically, has not acquired or does not seek to acquire; however, Management will continue to evaluate the possible impact that this Update may have on the accounting treatment of applicable elements and the financial presentation of these elements.
	Consolidation In February 2015, FASB issued Accounting Standards Update No. 2015-02 (“Update 2015-02”), Amendments to the Consolidation Analysis, Consolidation (Topic 810). Update 2015-02 provides modifications to the evaluation of variable interest entities that may impact consolidation of reporting entities. Update 2015-02 is effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The Company currently consolidates variable interest entities and may create or acquire variable interest entities for future endeavors. Management is still evaluating the possible impact this update may have on the financial presentation of the Company’s consolidated financial statements.
