Significant Accounting Policies	'
	(1)  Summary of Significant Accounting Policies
	(a)  Description of Business
	UQM Technologies, Inc. and our wholly-owned subsidiaries are engaged in the research, development and manufacture of permanent magnet electric motors and the electronic controls for such motors. Our facility is located in Longmont, Colorado. Our revenue is derived primarily from product sales to customers in the commercial truck, bus, automotive, marine and military markets, and from contract research and development services. We are impacted by other factors such as the continued receipt of contracts from industrial and governmental parties, our ability to protect and maintain the proprietary nature of our technology, continued product and technological advances and our ability, together with our partners, to commercialize our products and technology.
	(b)  Principles of Consolidation
	The consolidated financial statements include the accounts of UQM Technologies, Inc. and those of all majority-owned or controlled subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
	(c)  Cash and Cash Equivalents and Short-term Investments
	We consider cash on hand and investments with original maturities of three months or less to be cash and cash equivalents. Investments with original maturities of greater than three months and less than one year from the balance sheet date are classified as short-term.
	We limit our cash and cash equivalents and investments to high quality financial institutions in order to minimize our credit risk. We maintain cash and cash equivalent balances with financial institutions that exceed federally insured limits. We have not experienced any losses related to these balances and management believes our credit risk to be minimal.
	(d)  Investments
	We have an investment policy approved by the Board of Directors that governs the quality, acceptability and dollar concentration of our investments. Under the policy, we may invest in marketable securities consisting primarily of commercial paper, asset-backed and mortgage-backed notes and bank certificates of deposits with original maturities beyond three months. All marketable securities are held in our name at two major financial institutions that hold custody of the investments. All of our investments are held-to-maturity investments as we have the positive intent and ability to hold until maturity. These securities are recorded at amortized cost.
	The amortized cost and unrealized gain or loss of our investments at March 31, 2014 and March 31, 2013 were:
				31-Mar-14						31-Mar-13
				Amortized Cost			Gain (Loss)			Amortized Cost			Gain (Loss)

	Six months to one year			63,029			-
	Over one year			-			62,436
			$	63,029		$	62,436
	(e)  Accounts Receivables
	We extend unsecured credit to many of our customers following a review of the customers’ financial condition and credit history. Our sales are conducted through acceptance of customer purchase orders or in some cases through supply agreements. For credit qualified customers, our standard terms are net 30 days. For international customers without an adequate credit rating, our typical terms are irrevocable letter of credit or cash payment in advance of delivery. We establish an allowance for uncollectable accounts based upon a number of factors including the length of time trade receivables are past due, the customer’s ability to pay its obligation to us, the condition of the general economy, estimates of credit risk, historical trends and other information. We write off accounts receivable when they become uncollectible against our allowance for doubtful accounts receivable. At March 31, 2014 and 2013, we had an allowance for doubtful accounts receivable of zero and $3,838,092,  respectively. The following represents activity under our allowance for doubtful accounts receivable for the fiscal years ended March 31, 2014, 2013 and 2012:
						Additions

	Year ended March 31, 2012
	Allowance for doubtful accounts- deducted											-
	from accounts receivable		$	-			127,697			-					$	127,697
	(f)   Inventories
	Inventories are stated at the lower of cost or market. Cost is determined by the first-in, first-out method. We charge directly to expense slow moving or obsolete inventory items during the period we assess the value of such inventory to be impaired. For the fiscal years ended March 31, 2014, 2013 and 2012, we impaired inventory of $5,047, $8,928 and $10,169, respectively.
	(g)   Property and Equipment
	Property and equipment are stated at cost, unless the asset was acquired, in part, with U.S. Department of Energy (“DOE”) grant funds, in which case it is stated at cost net of DOE reimbursements. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from three to five years, except for buildings, which are depreciated over 27.5 years. Maintenance and repairs are charged to expense as incurred. Depreciation expense for the fiscal years ended March 31, 2014, 2013 and 2012 was $1,098,622, $1,218,812 and $1,139,821, respectively, and was reported in operating costs and expenses on the Consolidated Statements of Operations.
	(h)   Patent and Trademark Costs
	Patent and trademark costs consist primarily of legal expenses, and represent those costs incurred by us for the filing of patent and trademark applications. Amortization of patent and trademark costs is computed using the straight-line method over the estimated useful life of the asset, typically 13 years for patents, and 40 years for trademarks. Amortization expense for the fiscal years ended March 31, 2014, 2013 and 2012 was $37,399, $34,022, and $39,137, respectively.
	(i)   Impairment of Long-Lived Assets
	We periodically evaluate whether circumstances or events have affected the recoverability of long-lived assets including intangible assets with finite useful lives. The assessment of possible impairment is based on our ability to recover the carrying value of the asset or groups of assets from expected future cash flows (undiscounted and without interest charges) estimated by management. If expected future cash flows are less than the carrying value, an impairment loss is recognized to adjust the asset to fair value as determined by expected discounted future cash flows.
	(j)   Product Warranties
	Our warranty policy generally provides three months to three years of coverage depending on the product. We record a liability for estimated warranty obligations at the date products are sold. The estimated cost of warranty coverage is based on our actual historical experience with our current products or similar products. For new products, the required reserve is based on historical experience of similar products until sufficient historical data has been collected on the new product. Adjustments are made as new information becomes available. The following is a summary of warranty activity for the fiscal years ended March 31, 2014, 2013 and 2012:
						Additions
			Balance at			Charged to			Charged to
			Beginning			Costs and			Other						Balance at
			of Year			Expenses			Accounts			Deductions			End of Year
	Year ended March 31, 2014
	Accrued warranty cost		$	77,393			164,567			-		66,299	(A)		$	175,661
	Year ended March 31, 2013
	Accrued warranty cost		$	154,978			58,676			-		136,261	(A)		$	77,393
	Year ended March 31, 2012
	Accrued warranty cost		$	89,463			196,815			-		131,300	(A)		$	154,978
	Note (A) Represents actual warranty payments for units returned under warranty
	(k)  Revenue and Cost Recognition
	Revenue from sales of products is generally recognized at the time title to the goods and the benefits and risks of ownership passes to the customer, which is typically when products are shipped based on the terms of the customer purchase agreement.
Revenue relating to long-term fixed price contracts is recognized using the percentage of completion method. Under the percentage of completion method, contract revenues and related costs are recognized based on the percentage that costs incurred to date bear to total estimated costs. Changes in job performance, estimated profitability and final contract settlements may result in revisions to cost and revenue, and are recognized in the period in which the revisions are determined. Contract costs include all direct materials, subcontract and labor costs and other indirect costs. Selling, general and administrative costs are charged to expense as incurred. At the time a loss on a contract becomes known, the entire amount of the estimated loss is accrued.
The aggregate of costs incurred and estimated earnings recognized on uncompleted contracts in excess of related billings is shown as a current asset, and billings on uncompleted contracts in excess of costs incurred and estimated earnings is shown as a current liability.
(l)   Government Grants
The Company recognizes revenue and cost reimbursements from government grants when it is probable that the Company will comply with the conditions attached to the grant arrangement and the grant proceeds will be received. Government grants are recognized in the Consolidated Statements of Operations on a systematic basis over the periods in which the Company recognizes the related costs for which the government grant is intended to compensate. Specifically, when government grants are related to reimbursements for cost of revenues or operating expenses, the government grants are recognized as a reduction of the related expense in the Consolidated Statements of Operations. For government grants related to reimbursements of capital expenditures, the government grants are recognized as a reduction of the basis of the asset and recognized in the Consolidated Statements of Operations over the estimated useful life of the depreciable asset as reduced depreciation expense.
The Company records government grants receivable in the Consolidated Balance Sheets in accounts receivable.
(m) Income Taxes
The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The valuation of deferred tax assets may be reduced if future realization is not assured. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income tax expense or benefit in the period that includes the enactment date. The Company has unexpired net operating losses and research and development credits carrying forward into current years that date from the tax year 1999 and 2001, respectively. As such, all federal tax returns from 1999 to the present are subject to audit.
(n) Research and Development
Costs of researching and developing new technology, or significantly altering existing technology, are expensed as incurred.
(o)  Loss Per Common Share
Basic loss per share is computed by dividing loss attributable to common stockholders by the weighted average number of common shares outstanding during the periods presented. Diluted loss per share is computed by dividing loss attributable to common stockholders by all outstanding and potentially dilutive shares during the periods presented, unless the effect is antidilutive. At March 31, 2014, 2013 and 2012,  640,979 and 358,855 and 167,680 shares of common stock issued but not yet vested, respectively under the Stock Bonus Plan, were being held by the Company. For fiscal years 2014, 2013 and 2012, 267,911, 32,681 and 16,487 shares were potentially includable in the calculation of diluted loss per share under the treasury stock method but were not included, because to do so would be antidilutive.  At March 31, 2014, 2013 and 2012, options to purchase 3,342,627, 4,282,001 and 3,254,905 shares of common stock, respectively, and warrants to purchase 1,489,733, zero and zero shares of common stock, respectively, were outstanding. For the fiscal years ended March 31, 2014, 2013 and 2012, options and warrants for 3,371,161, 2,872,257 and 3,201,569 shares were not included in the computation of diluted loss per share because the option exercise price was greater than the average market price of the common stock.  In-the-money options and warrants determined under the treasury stock method to acquire 462,104, zero and 2,834 shares of common stock for the fiscal years ended March 31, 2014, 2013 and 2012, respectively, were potentially includable in the calculation of diluted loss per share but were not, because to do so would be antidilutive.
(p)  Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

	Impairments for the fiscal year ended March 31, 2012 consist solely of capitalized legal fees associated with the preparation and filing of patent applications that were subsequently abandoned. Because no patents were issued, none of these patent application costs were amortized prior to their impairment.

Government Grants	'
	(7)  Government Grant
	We have a grant (the “Grant”) with the DOE under the American Recovery and Reinvestment Act for reimbursements up to a maximum of $32.4 million. The Grant provides funds to facilitate the manufacture and deployment of electric drive vehicles, batteries and electric drive vehicle components in the United States. Pursuant to the terms of the Agreement, the DOE will reimburse us for 50 percent of qualifying costs for the purchase of facilities, tooling and manufacturing equipment, and for engineering related to product qualification and testing of our electric propulsion systems. The period of the Grant is through January 12, 2015. We recognize government grant reimbursements when it is probable that the Company will comply with the conditions attached to the grant arrangement and the grant proceeds will be received.
	The Grant is also subject to our compliance with certain reporting requirements. The American Recovery and Reinvestment Act imposes minimum construction wages and labor standards for projects funded by the Grant. If we dispose of assets acquired using Grant funding, we may be required to reimburse the DOE upon such sale date if the fair value of the asset on the date of disposition exceeds $5,000. The amount of any such reimbursement shall be equal to 50 percent of the fair value of the asset on the date of disposition.
	While UQM has exclusive patent ownership rights for any technology developed with Grant funds, we are required to grant the DOE a non-exclusive, non-transferable, paid-up license to use such technology.
	During the second quarter of the current fiscal year, we changed our cumulative estimate of reimbursable rates under the Grant which resulted in an increase in our reimbursement of costs recorded for the fiscal year ended March 31, 2014 of $958,000.
	At March 31, 2014, we had received reimbursements from the DOE under the Grant totaling approximately $24.4 million and had grant funds receivable of approximately $0.6 million.
	The application of grant funds to the recorded value of eligible capital asset purchases under the Grant as of March 31, 2014 and March 31, 2013 are as follows:

	Deferred compensation under executive employment agreements represents the future compensation potentially payable under the retirement and voluntary termination provisions of executive employment agreements. The value of the Level 3 liability in the foregoing table was determined using a discounted cash flow model.  The significant unobservable input used in the calculation is a discount rate of 14 percent, which is based on the expected cost of capital for the Company.  A 1 percent change in this discount rate would result in approximately a $2,500 change in the recorded value of the liability as of March 31, 2014.

	In February, 2014, we completed a follow-on offering consisting of 2,864,872 shares of our common stock, and common stock purchase warrants to purchase 1,432,436 shares of our common stock. The warrants have an exercise price of $2.1275 per whole share of common stock and are exercisable on or after August 6, 2014 and on or before August 5, 2018.  In addition, the placement agent was issued warrants to purchase 57,297 shares of common stock, on substantially the same terms as the warrants issued to the purchasers. Cash proceeds, net of offering costs, were $4,911,933. The fair value of the warrants at the time of issuance was $1,832,943, and was recorded as additional paid-in capital. This fair value was determined using the Black-Scholes option pricing model with the following assumptions: a term of four and a half years, risk-free interest rate of 1.5%, volatility of 78.3%, and dividend yield of zero. Warrants to acquire 1,489,733 and zero shares of our common stock were outstanding at March 31, 2014 and 2013, respectively.

	Stock Option Plans
	As of March 31, 2014, we had 1,100,000 shares of common stock authorized and 14,870 shares of common stock available for future grant to employees and consultants under our 2012 Equity Incentive Plan (“Plan”).  The term of the 2012 Plan is ten years. Under the 2012 Plan, the exercise price of each option is set at the fair value of the common stock on the date of grant and the maximum term of the option is ten years from the date of grant. Options granted to employees generally have a ten year term and vest ratably over a three-year period. The maximum number of options that may be granted to an employee under the Plan in any calendar year is 500,000 options. Forfeitures under the Plan are available for re-issuance at any time prior to expiration of the Plan in 2022. Options granted under the Plan to employees require the option holder to abide by certain Company policies, which restrict their ability to sell the underlying common stock. Prior to the adoption of the 2012 Plan, we issued stock options under our 2002 Equity Incentive Plan. Forfeitures under the 2002 Equity Incentive Plan may not be re-issued.
	We also have a Stock Option Plan for Non-Employee Directors (“Directors Plan”) pursuant to which Directors may elect to receive stock options in lieu of cash compensation for their services as directors. As of March 31, 2014, we had 1,000,000 shares of common stock authorized and 224,173 shares of common stock available for future grant under the Directors Plan. Option terms range from three to ten years from the date of grant. Option exercise prices are equal to the fair value of the common shares on the date of grant. Options granted under the plan vest immediately. Forfeitures under the Directors Plan are available for re-issuance at a future date.
	Stock Bonus Plan
	We have a Stock Bonus Plan (“Stock Plan”) administered by the Board of Directors. As of March 31, 2014, we had 1,954,994 shares of common stock authorized and there were 47,149 shares of common stock available for future grant under the Stock Plan.  Under the Stock Plan, shares of common stock may be granted to employees, key consultants, and directors who are not employees as additional compensation for services rendered. Vesting requirements for grants under the Stock Plan, if any, are determined by the Board of Directors at the time of grant.
	Stock Purchase Plan
	We have established a Stock Purchase Plan under which eligible employees may contribute up to 10 percent of their compensation to purchase shares of our common stock at 85 percent of the fair market value at specified dates.  At March 31, 2014, we had 700,000 shares of common stock authorized and 307,650 shares of common stock available for issuance under the Stock Purchase Plan.
	Share-Based Compensation Expense
	We use the straight-line attribution method to recognize share-based compensation costs over the requisite service period of the award. The exercise price of options is equal to the market price of our common stock (defined as the closing price reported by the NYSE MKT) on the date of grant. We adjust share-based compensation on a quarterly basis for changes to the estimate of expected equity award forfeitures based on actual forfeiture experience.  The effect of adjusting the forfeiture rate for all expense amortization is recognized in the period the forfeiture estimate is changed. The effect of forfeiture adjustments during the years ended March 31, 2014, 2013 and 2012 was insignificant.
	We use the Black-Scholes-Merton option pricing model for estimating the fair value of stock option awards. The expected volatility and the expected life of options granted are based on historical experience, and the risk free interest rate is obtained from the U.S. Department of the Treasury daily yield curve rates. The weighted average estimated values of employee and director stock option grants, as well as the weighted average assumptions that were used in calculating such values during the years ended March 31, 2014, 2013 and 2012, were based on estimates at the date of grant as follows:
			Year Ended March 31,

	Deferred tax assets, net of valuation allowance		$	-		$	-
	As of March 31, 2014 and March 31, 2013, respectively, we had net operating loss (“NOL”) carry-forwards of approximately $70.9 million and $67.3 million for U.S. income tax purposes that expire in varying amounts through 2034. Approximately $5.3 million of the net operating loss carry-forwards are attributable to stock options, the benefit of which will be credited to additional paid-in capital if realized. However, due to the provisions of Section 382 of the Internal Revenue Code, the utilization of a portion of these NOLs may be limited. Future ownership changes under Section 382 could occur that would result in additional Section 382 limitations, which could further restrict the use of NOLs. In addition, any Section 382 limitation could reduce our ability for utilization to zero if we fail to satisfy the continuity of business enterprise requirement for the two-year period following an ownership change.
	The valuation allowance for deferred tax assets of $26.1 million and $25.2 million at March 31, 2014 and 2013, respectively, relates principally to the uncertainty of the utilization of deferred tax assets in various tax jurisdictions. The Company continually assesses both positive and negative evidence to determine whether it is more-likely-than-not that the deferred tax assets can be realized prior to their expiration. Based on the Company’s assessment it has determined the deferred tax assets are not currently realizable.
	We have not recorded any potential liability for uncertain tax positions taken on our tax returns.
	We may, from time to time, be assessed interest or penalties by major tax jurisdictions, although any such assessments historically have been minimal and immaterial to our financial results. Penalties are recorded in selling, general and administrative expenses and interest paid or received is recorded in interest expense or interest income, respectively, in the consolidated statements of operations.

	We have established a 401(k) Savings Plan (“401K Plan”) under which eligible employees may contribute up to 15 percent of their compensation. Employees over the age of 18 are eligible immediately upon hire to participate in the 401K Plan. At the direction of the participants, contributions are invested in several investment options offered by the 401K Plan. We currently match 33 percent of participants’ contributions, subject to certain limitations. These matching contributions vest ratably over a three-year period. Matching contributions to the 401K Plan were $132,471, $149,311, and $135,825, for the years ended March 31, 2014, 2013, and 2012, respectively.
