SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	2	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation - The consolidated financial statements include the accounts of Aware, Inc. and its subsidiary.  All significant intercompany transactions have been eliminated.
	Use of Estimates – The preparation of our financial statements in conformity with accounting principles generally accepted in the United States of America requires us 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 amount of revenues and expenses during the reporting period.  The most significant estimates included in the financial statements pertain to revenue recognition, reserves for doubtful accounts, useful lives of fixed assets, valuation allowance for deferred income tax assets, and accrued liabilities.  Actual results could differ from those estimates.
	Fair Value Measurements - The Financial Accounting Standards Board (“FASB”) Codification defines fair value, and establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to the unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under the FASB Codification are: i) Level 1 – valuations that are based on quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date; ii) Level 2 – valuations that are based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly; and iii) Level 3 – valuations that require inputs that are both significant to the fair value measurement and unobservable.
	Cash and cash equivalents, which primarily include money market mutual funds, were $72.7 million and $71.1 million as of December 31, 2013 and December 31, 2012, respectively. We classified our cash equivalents of $68.6 million and $67.1 million as of December 31, 2013 and 2012, respectively, within Level 1 of the fair value hierarchy because they are valued using quoted market prices.
	Our investments, which consist of high yield corporate debt securities, are also classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. We categorize our investments as available-for-sale securities, and carry them at fair value in our financial statements.  We had $2.8 million and $2.0 million of available-for-sale investments as of December 31, 2013 and December 31, 2012, respectively.
	As of December 31, 2013, our assets that are measured at fair value on a recurring basis and whose carrying values approximate their respective fair values include the following (in thousands):
			Fair Value Measurement at December 31, 2013 Using:
			Quoted Prices in		Significant Other		Significant
			Active Markets for		Observable Inputs		Unobservable
			Identical Assets				Inputs
			(Level 1)		(Level 2)		(Level 3)
	Corporate debt securities		$	2,754	$	-	$	-
	Money market funds (included in cash and cash equivalents)			68,556
	Total		$	71,310	$	-	$	-
	As of December 31, 2012, our assets that are measured at fair value on a recurring basis and whose carrying values approximate their respective fair values include the following (in thousands):
			Fair Value Measurement at December 31, 2012 Using:
			Quoted Prices in		Significant Other		Significant
			Active Markets for		Observable Inputs		Unobservable
			Identical Assets				Inputs
			(Level 1)		(Level 2)		(Level 3)
	Corporate debt securities		$	2,010	$	-	$	-
	Money market funds (included in cash and cash equivalents)			67,050
	Total		$	69,060	$	-	$	-
	Cash and Cash Equivalents – Cash and cash equivalents, which consist primarily of money market funds and demand deposits, are stated at fair value. All highly liquid investments purchased with an original maturity of three months or less are considered cash equivalents. Our cash balances exceed the Federal Deposit Insurance Corporation limits. The Company does not believe it is exposed to significant credit risk related to cash and cash equivalents.
	Investments - At December 31, 2013 and 2012, we categorized all investment securities as available-for-sale, since we may liquidate these investments currently.  In calculating realized gains and losses, cost is determined using specific identification. Unrealized gains and losses on available-for-sale securities are excluded from earnings and reported in a separate component of stockholders’ equity called Accumulated Comprehensive Income.
	Realized gains on investments were $23,000 and $85,000 in the years ended December 31, 2013 and 2012, respectively.  There were no realized gains or losses on investments in the year ended December 31, 2011.
	Unrealized losses on investments were $156,000, $30,000, and $20,000 in the years ended December 31, 2013, 2012, and 2011.
	The amortized cost of our corporate debt securities was $3.0 million at December 31, 2013. Corporate debt securities comprising investments mature in 2015 to 2018.
	Allowance for Doubtful Accounts – Accounts are charged to the allowance for doubtful accounts as they are deemed uncollectible based on a periodic review of the accounts.
	Inventories – Inventories are stated at the lower of cost or net realizable value. Cost is determined by the first-in, first-out (“FIFO”) method.  We evaluate all inventories for net realizable value on a quarterly basis, and record provisions for excess and obsolete inventory when required.  There was no reserve for excess and obsolete inventory as of December 31, 2013.
	Property and Equipment – Property and equipment is stated at cost.  Depreciation and amortization of property and equipment is provided using the straight-line method over the estimated useful lives of the assets. Upon retirement or sale, the costs of the assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss on disposal is included in the determination of income or loss.  Expenditures for repairs and maintenance are charged to expense as incurred.
	The estimated useful lives of assets used by us are:
		Building	30 years
		Building improvements	5 to 20 years
		Furniture and fixtures	5 years
		Computer, office & manufacturing equipment	3 years
		Purchased software	3 years
	Impairment of Long-Lived Assets – We review long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate.  Each impairment test is based on a comparison of the undiscounted cash flows estimated to be generated by those assets over their estimated economic life to the related carrying value of those assets to determine if the assets are impaired. If an impairment is indicated, the asset is written down to its estimated fair value.  The cash flow estimates used to identify the potential impairment reflect our best estimates using appropriate assumptions and projections at that time.  We believe that no significant impairment of our long-lived assets has occurred as of December 31, 2013 and 2012.
	Revenue Recognition – We recognize revenue when there is persuasive evidence of an arrangement, the sales price is fixed or determinable, collection of the related receivable is reasonably assured, and delivery has occurred or services have been rendered.
	Persuasive evidence of an arrangement: We use contracts signed by both the customer and us or written purchase orders issued by the customer as evidence of an arrangement.
	Product delivery: We deem delivery to have occurred: (i) upon shipment when products are shipped FOB shipping point, or (ii) upon delivery at a customer’s location when products are shipped FOB destination, or (iii) when software is delivered electronically.  If customer acceptance provisions apply, revenue is not recognized until delivery has occurred and we have received such acceptance. If we are required to provide installation services, revenue is not recognized until installation is complete.
	Fixed or determinable fee: We consider fees to be fixed or determinable if the fee is not subject to refund or adjustment and the payment terms are within normal established practices. If the fee is not fixed or determinable, we recognize the revenue as amounts become due and payable.
	Collection is deemed probable: We conduct a credit review for significant transactions at the time of the arrangement to determine the credit-worthiness of the customer. Collection is deemed probable if we expect that the customer will pay amounts under the arrangement as payments become due.
	We categorize revenue as software licenses, software maintenance, services, hardware sales, or royalties. In addition to the general revenue recognition policies described above, specific revenue recognition policies apply to each category of revenue.
	Software licenses
	Software licenses consist of revenue from the sale of software licenses for biometrics and imaging applications.  We recognize revenue from software licenses upon delivery when licenses are sold in single element arrangements.
	Software maintenance
	Software maintenance consists of revenue from the sale of software maintenance contracts for biometrics and imaging software.  Software maintenance contracts entitle customers to receive software support and software updates, if and when they become available, during the term of the maintenance contract. We recognize software maintenance revenue ratably over the related contract period.
	Services
	Service revenue consists of fees from biometrics customers for engineering services we provide to them. We recognize services revenue as services are delivered when services are sold in single element arrangements.
	Hardware sales
	Hardware sales consist of sales of biometrics equipment to a single U.S. government customer.  We recognize hardware sales upon delivery and acceptance of the equipment by the customer.
	Royalties
	Royalty revenue consists of royalties we receive under DSL silicon IP contracts with customers that have incorporated our intellectual property into their products. Since we cannot reasonably estimate royalty revenue, such revenue is recognized in the quarter in which a final report is received from a customer. Royalty reports are typically received in the quarter immediately following the quarter in which sales of royalty-bearing products occur.
	Multiple element arrangements
	In addition to selling software licenses, software maintenance and services in single element arrangements, we also sell these three products and hardware as part of multiple element arrangements.  The various combinations of multiple element arrangements and our revenue recognition for each are described as follows:
		●	Software licenses and software maintenance. When software licenses and software maintenance contracts are sold together, we recognize software license revenue upon delivery, provided we have vendor specific objective evidence (“VSOE”) for the fair value of the maintenance contract fee, and we recognize the fair value of maintenance contract revenue ratably over the related contract period.
		●	Software licenses and services. When software licenses and engineering services are sold together, the total fee is generally recognized by applying contract accounting. We have adopted the percentage-of-completion method of contract accounting, and we generally use an input method (i.e., labor hours) to determine our completion percentage. The software license portion of the arrangement is classified as software license revenue and the engineering services portion is classified as services revenue.
		●	Software licenses, software maintenance and services. When we sell software licenses, software maintenance and services together, revenue is recognized as follows: i) software maintenance revenue is separated from the other two elements and is recognized ratably over the related software maintenance contract period; provided we have VSOE for the fair value of the maintenance element; and ii) the total fee from the software license and engineering service elements is recognized by applying the contract accounting method described in the previous paragraph.
		●	Hardware sales, software maintenance, and services. We have a multiple element arrangement with one customer that involves the delivery of hardware, maintenance, and services.  We determined that these elements qualified as separate units of accounting because they have value to the customer on a standalone basis.  We recognize revenue from this arrangement as follows: i) hardware revenue is recognized upon delivery and acceptance of the equipment by the customer; ii) maintenance revenue is recognized ratably over the related contract period; and iii) service revenue is recognized as services are delivered.
	Income Taxes – We compute deferred income taxes based on the differences between the financial statement and tax basis of assets and liabilities using enacted rates in effect in the years in which the differences are expected to reverse.  We establish a valuation allowance to offset temporary deductible differences, net operating loss carryforwards and tax credits when it is more likely than not that the deferred tax assets will not be realized.
	We recognize the tax benefit from an uncertain tax position only if it is more-likely-than-not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the tax position. The evaluation of an uncertain tax position is based on factors that include, but are not limited to, changes in the tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, and changes in facts or circumstances related to a tax position.  Any changes to these estimates, based on the actual results obtained and/or a change in assumptions, could impact our tax provision in future periods.  Interest and penalty charges, if any, related to unrecognized tax benefits would be classified as a provision for income tax in the statement of income.
Capitalization of Software Costs – We capitalize certain internally developed software development costs after technological feasibility of the product has been established.  No software costs were capitalized for the years ended December 31, 2013, 2012 and 2011, because such costs incurred subsequent to the establishment of technological feasibility, but prior to commercial availability, were immaterial.
Research and Development Costs – Costs incurred in the research and development of our products are expensed as incurred.
Concentration of Credit Risk – At December 31, 2013 and 2012, we had cash and cash equivalents, in excess of federally insured deposit limits of approximately $72.4 million and $70.8 million, respectively.
Concentration of credit risk with respect to net accounts receivable consisted of $2.7 million, $0.2 million, $0.2 million, $0.2 million and $0.2 million with five customers, respectively, at December 31, 2013, and $1.1 million, $0.6 million, $0.5 million, $0.4 million and $0.3 million with five customers, respectively, at December 31, 2012.
Concentration of credit risk with respect to our investment portfolio consisted of $0.8 million, $0.5 million, $0.5 million, $0.5 million, and $0.4 million with five issuers of corporate debt securities, respectively, at December 31, 2013, and $1.0 million and $1.0 million with two issuers of corporate debt securities, respectively, at December 31, 2012.
Stock-Based Compensation – We grant stock options and stock to our employees and directors.  We measure stock-based compensation cost at the grant date based on the fair value of the award and recognize stock-based compensation expense on a straight-line basis over the requisite service period of the award.
We use the Black-Scholes option valuation model to estimate the fair value of stock option awards. This valuation model takes into account the exercise price of the award, as well as a variety of significant assumptions.  The assumptions used to estimate the fair value of stock options include the expected term, the expected volatility of our stock over the expected term, the risk-free interest rate over the expected term, and our expected annual dividend yield.
For stock awards, we determine the fair value of the award by using the fair market value of our stock on the date of grant; provided the number of shares in the grant is fixed on the grant date.
Computation of Earnings per Share – Basic earnings per share is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding.  Diluted earnings per share is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding plus additional common shares that would have been outstanding if dilutive potential common shares had been issued.  For the purposes of this calculation, stock options are considered common stock equivalents in periods in which they have a dilutive effect.  Stock options that are antidilutive are excluded from the calculation.
Fair Value of Financial Instruments – The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value because of their short-term nature. The carrying amount of investments is based on the fair value of the individual securities in our investment portfolio.
Advertising Costs – Advertising costs are expensed as incurred and were not material for 2013, 2012, and 2011.
Recent Accounting Pronouncements – There were no recently issued accounting pronouncements applicable to us that we had not adopted as of December 31, 2013.
Reclassifications - Certain prior period amounts have been reclassified to be consistent with the current period presentation, particularly as a result of the discontinued operations presentation of our DSL service assurance business. See Note 4 to the Consolidated Financial Statements.
Segments – Following the shutdown of our DSL Service Assurance Segment as described in Note 4, we organize ourselves into a single segment reporting to the chief operating decision makers. We have sales outside of the United States, which are described in Note 10.  All long-lived assets are maintained in the United States.

PATENT RELATED INCOME	'
	3	PATENT RELATED INCOME
	In the years ended December 31, 2013 and 2012, we derived patent related income from two sources, which are described below:
	Gain on sale of patent assets. In 2011, we engaged an intellectual property law firm to help us conduct a process to sell a portion of our patent portfolio pertaining to wireless and certain DSL patents. The process produced two significant patent sales for a total of $86.4 million of net gains in the year ended December 31, 2012. This income was included on a separate line of the consolidated statements of income and comprehensive income entitled “Gain on sale of patent assets.”  The two patent sales are described below:
	Wireless patent sale.  On April 26, 2012, we entered into an agreement with an unaffiliated third party to sell a portion of our patent portfolio pertaining to wireless technology for $75.0 million. The proceeds from the sale were reduced by $3.8 million of transaction costs, which consisted primarily of fees from the law firm that assisted us in the sale.  The transaction closed in June 2012 and resulted in a gain of $71.2 million.
	DSL patent sale.  On August 22, 2012, we entered into an agreement with an unaffiliated third party to sell a portion of our patent portfolio pertaining to digital subscriber line (“DSL”) technology for $16.0 million. The proceeds from the sale were reduced by $0.8 million of transaction costs, which also consisted primarily of fees from the law firm that assisted us in the sale.  The transaction closed in September 2012 and resulted in a gain of $15.2 million.
	Income from patent arrangement. In December 2010, we entered into an arrangement with an unaffiliated third party under which we assigned patents in return for royalties on proceeds from patent monetization efforts by the third party.  In the years ended December 31, 2013 and 2012, we recorded income related to this arrangement of $0.8 million and $1.1 million, respectively. Such income was included on a separate line of the consolidated statements of income and comprehensive income entitled “Income from patent arrangement.”

	Our board of directors approved the shutdown of our DSL service assurance hardware and software product lines in 2012 and 2013, respectively. Both product lines were previously components of our DSL Service Assurance Segment. Results from the DSL Service Assurance Segment have been reported as discontinued operations because we no longer have any significant continuing involvement with, or cash flows from, this segment.

	The consolidated statements of income and comprehensive income for the years ended December 31, 2012 and 2011 have been reclassified to reflect the effect of discontinued operations as set forth above.
	We incurred one-time costs related to the shutdown of the DSL service assurance hardware and software product lines.  Shutdown costs for each product line were:
	DSL service assurance hardware product line.  In 2012, we incurred one-time shutdown costs related to the hardware product line of approximately $282,000, the majority of which were severance and employee-related costs.  All such costs were incurred, paid, and included in loss from discontinued operations for the year ended December 31, 2012.
	DSL service assurance software product line.  In 2013, we incurred one-time shutdown costs related to the software product line of approximately $2.9 million. Such costs comprise: i) $3.7 million of payments to customers to terminate contracts, which were offset by $1.2 million of deferred revenue obligations that were relieved as a result of such contract terminations; ii) $311,000 of severance and employee-related costs; and iii) $48,000 of asset write-offs.  All such costs were incurred and included in loss from discontinued operations for the year ended December 31, 2013. All DSL service assurance software product line exit costs were paid in 2013, with the exception of $90,000 of severance costs, which were paid in early January 2014.

	Total income tax expense for the year ended December 31, 2013 was $1.2 million, including $1.9 million that was recorded in continuing operations less a tax benefit of $0.7 million that was recorded in discontinued operations. Income tax expense for 2013 was based on the U.S. statutory rate of 34%, increased by state income taxes.  Tax expense in 2013 also reflects two items related to 2012, including:
		●	a tax benefit of $95,000 related to the 2012 research tax credit. This credit was extended retroactively back to January 1, 2012, by the American Taxpayer Relief Act of 2012, which was enacted on January 2, 2013; and
		●	a tax benefit of $148,000 related to a reduction in the estimate of the 2012 tax expense recorded in our 2012 financial statements.
	Total income tax expense for the year ended December 31, 2012 was $20.4 million, including $20.5 million that was recorded in continuing operations less a tax benefit of $51,000 that was recorded in discontinued operations. The Company’s actual tax liability for 2012 was $7.8 million as taxes that were currently payable were reduced by a $14.4 million equity adjustment. This equity adjustment is described more fully below.
	In 2012, we used a significant portion of our available deferred tax assets to reduce income taxes on pre-tax income. A substantial portion of the deferred tax assets we utilized comprised cumulative deductions for stock options in excess of book expense. Under income tax accounting rules, the portion of tax benefits attributable to such deductions must be recorded as an adjustment to equity versus a reduction of income tax expense. In the year ended December 31, 2012, the tax benefits from such stock-based awards were $14.4 million, which we recorded as an equity adjustment to additional paid-in capital.
	Income tax expense in 2012 was also reduced by a $1.8 million reversal of the valuation allowance on our remaining deferred tax assets at December 31, 2012. We reversed the valuation allowance because based on all the available evidence, we believed that it is more likely than not that our deferred tax assets will be realizable.  In reaching this determination, we evaluated: i) our most recent years operating results; ii) our future financial plans; and iii) the nature of the components comprising deferred tax assets at December 31, 2012.
		As of December 31, 2013 and 2012, we had deferred tax assets for which we had recorded no valuation allowance.  The principal components of deferred tax assets were as follows at December 31 (in thousands):
			2013			2012
	Capitalized research and development costs		$	364		$	817
	Research and development and other tax credit carryforwards			-			27
	Other			781			916
	Total			1,145			1,760
	Less valuation allowance			(-	)		(-	)
	Deferred tax assets, net		$	1,145		$	1,760
	We will continue to assess the level of valuation allowance required in future periods. Should evidence regarding the realizability of tax assets change at a future point in time, the valuation allowance will be adjusted accordingly.
	As a result of significant taxable income in 2012 and the utilization of research and development credits thereon, we conducted a review to determine whether any of our prior year research and development tax credits represented an uncertain tax position.  Based on that review, we determined that $1.9 million of federal credits and $1.0 million of state credits could not be supported and therefore, those credits were written off.  In addition to the write-off, we also determined that $1.9 million of federal credits and $1.0 million of state credits represented an uncertain tax position for which we established a valuation allowance.  A rollforward of the uncertain tax position related to our research and development tax credits is as follows (in thousands):
		Uncertain tax positions at December 31, 2011		$	-
		Increase due to positions taken in prior periods			2,945
		Uncertain tax positions at December 31, 2012		$	2,945
		Increase due to positions taken in prior periods			-
		Uncertain tax positions at December 31, 2013		$	2,945
	Uncertain tax positions of $2.6 million will impact our tax rate if realized.  The difference between this amount and the total uncertain tax positions in the table above is the federal tax effect on state tax credits.
	In addition to deferred tax assets carried on our balance sheet, we also had net federal and state research and development credit carryforwards available at December 31, 2013 of $4.9 million and $0.7 million.  These credits were not recorded as tax assets as they relate to excess stock compensation deductions that may not be recorded as tax assets under generally accepted accounting principles until the amounts have been utilized to reduce our tax liability. To the extent that these assets are used to reduce future taxes, the benefit will be recorded as a reduction to additional paid-in capital. In 2013, we recorded a tax benefit of $128,000 to equity related to the use of these tax credits to reduce our tax liability.
	Our policy is to recognize interest and penalties related to uncertain tax positions in income tax expense.  As of December 31, 2013, we had no accrued interest or penalties related to uncertain tax positions.
	The tax years from 1998 through 2013 are subject to examination by the IRS and state tax authorities.

EQUITY AND STOCK COMPENSATION PLANS	'
	8.        EQUITY AND STOCK COMPENSATION PLANS
	Fixed Stock Option Plans – We have two fixed option plans.  Under our 1996 Stock Option Plan (“1996 Plan”), we were authorized to grant incentive stock options and nonqualified stock options to our employees and directors for up to 6,100,000 shares of common stock. There were no shares available for grant under the 1996 Plan as of December 31, 2013.  Under our 2001 Nonqualified Stock Plan (“2001 Plan”), we are authorized to grant nonqualified stock options, stock appreciation rights and stock awards to our employees and directors for up to 8,000,000 shares of common stock.  As of December 31, 2013, there were 4,632,086 shares available for grant under the 2001 Plan.
	Under both plans, options are granted at exercise prices as determined by the Board of Directors and have terms ranging from four to a maximum of ten years. Our options generally vest over three to five years, although we have granted options in the past that were 50% or fully vested on the date of grant.
	The following table presents stock-based employee compensation expenses included in our consolidated statements of income and comprehensive income (in thousands):
		Years ended December 31,
		2013			2012		2011
	Cost of services	$	34		$	16	$	29
	Research and development		81			51		110
	Selling and marketing		14			126		108
	General and administrative		533			83		859
	Loss from discontinued operations		-			45		171
	Stock-based compensation expense	$	662		$	321	$	1,277
	Stock-based compensation expenses in the preceding table include expenses associated with grants of: i) stock options; ii) stock appreciation rights (SARs); and iii) unrestricted shares of our common stock.  The method used to determine stock-based compensation expense for each type of equity grant is described in the following paragraphs.
	Stock Option and SAR Grants. For the years ended December 31, 2013, 2012, and 2011, we granted stock options for 0, 50,000, and 0 shares, respectively. No SARS were granted during the three year period ended December 31, 2013. We estimate the fair value of stock options and SARs using the Black-Scholes valuation model.
	The Black-Scholes valuation model takes into account the exercise price of the award, as well as a variety of significant assumptions. The assumptions used to estimate the fair value of stock options and SARs include the expected term, the expected volatility of our stock over the expected term, the risk-free interest rate over the expected term, and our expected annual dividend yield. We believe that the valuation technique and the approach utilized to develop the underlying assumptions are appropriate in calculating the fair values of stock options granted in the year ended December 31, 2012. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards.
	Specific assumptions used to determine the fair value of options granted during the years ended December 31, 2013, 2012 and 2011, using the Black-Scholes valuation model were:
		Year Ended		Year Ended	Year Ended
		December 31,		December 31,	December 31,
		2013		2012	2011
	Expected term (1)	n/a		5 years	n/a
	Expected volatility factor (2)	n/a		58-63%	n/a
	Risk-free interest rate (3)	n/a		0.92%	n/a
	Expected annual dividend yield	n/a		n/a	n/a
	(1) The expected term for each grant for the year ended December 31, 2012 was determined based on the contractual term of the option.
	(2) The expected volatility for each grant is estimated based on an average of historical volatility over a period of time which we believe to be representative of our future volatility.
	(3) The risk-free interest rate for each grant is based on the U.S. Treasury yield curve in effect at the time of grant for a period equal to the expected term of the stock option.
	We do not estimate our forfeiture rates as the actual forfeiture rate is known at the end of each reporting period due to the timing of our stock option vesting.
	Unrestricted Stock Grants.  Our 2001 Plan permits us to grant shares of unrestricted stock to our directors, officers and employees.  Stock-based compensation expense for stock grants is determined based on the fair market value of our stock on the date of grant; provided the number of shares in the grant is fixed on the grant date.
	We granted 130,000, 0, and 105,000 shares of unrestricted stock during the years ended December 31, 2013, 2012, and 2011, respectively. The accounting treatment of those awards is described below:
	Year ended December 31, 2013. In April 2013, we granted 130,000 shares of unrestricted stock to directors, officers and employees. The shares were issued in two equal installments shortly after June 30, 2013 and December 31, 2013. We expensed $623,000 of stock-based compensation expense related to this grant in the year ended December 31, 2013. There was no unamortized stock-based compensation charge associated with this stock grant as of December 31, 2013.
	We issued shares of common stock related to the April 2013 grant as follows: i) 51,374 net shares of common stock were issued in early July 2013 after employees surrendered 13,626 shares for which we paid $71,000 of withholding taxes on their behalf; and ii) 49,936 net shares of common stock were issued in early January 2014 after employees surrendered 15,064 shares for which we paid $92,000 of withholding taxes on their behalf.
	Year ended December 31, 2012. No shares of unrestricted stock were granted in 2012, however we granted shares of unrestricted common stock in 2010 that affected results for the year ended December 31, 2012. Activity in 2012 related to the 2010 stock grant was: i) 2012 stock-based compensation expense included $189,000 related to the 2010 grant; and ii) we issued 118,113 net shares of common stock after employees surrendered 33,441 shares for which we paid $174,000 of withholding taxes on their behalf.
	Year ended December 31, 2011. Our former President and CEO resigned in April 2011.  As part of his separation arrangement he was granted 105,000 shares of common stock, which resulted in a stock-based compensation charge of $362,000 in the year ended December 31, 2011. We issued 71,662 net shares of common stock after he surrendered 33,338 shares for which we paid $115,000 of withholding taxes on his behalf.
	The aforementioned 2010 stock grant also affected results for the year ended December 31, 2011. Activity in 2011 related to the 2010 stock grant was: i) 2011 stock-based compensation expense included $443,000 related to the 2010 grant; and ii) we issued a net of 157,988 shares of common stock after employees surrendered 36,998 shares for which we paid $109,000 of withholding taxes on their behalf.
	A summary of stock option transactions for our two fixed stock option plans for the years ended December 31, 2013, 2012, and 2011 are presented below:

	The number of option shares vested and expected to vest at December 31, 2013 was 1,004,989 and those options had a weighted average exercise price of $5.68.
	No stock options were granted in the years ended December 31, 2013 and 2011. All options granted during the year ended December 31, 2012 had exercise prices equal to the fair market value of our common stock on the date of grant, and the weighted average grant date fair values of options granted were $2.38.
	At December 31, 2013, the weighted average remaining contractual term for total options outstanding and total options exercisable was approximately 1 year for each.
	At December 31, 2013, the aggregate intrinsic value of options outstanding and options exercisable was approximately $0.4 million for each. The intrinsic value of a stock option is the amount by which the market value of the underlying stock exceeds the exercise price of the option.  The aggregate intrinsic value of options exercised during the year ended December 31, 2013 was approximately $4,000.
	The following table summarizes the stock options outstanding at December 31, 2013:
		Options Outstanding								Options Exercisable

At December 31, 2013, unrecognized compensation expense related to non-vested stock options was approximately $46,000, which is expected to be recognized over a weighted average period of 1.0 years.
We issue common stock from previously authorized but unissued shares to satisfy option exercises and purchases under our Employee Stock Purchase Plan.
Employee Stock Purchase Plan - In June 1996, we adopted an Employee Stock Purchase Plan (the “ESPP Plan”) under which eligible employees could purchase common stock at a price equal to 85% of the lower of the fair market value of the common stock at the beginning or end of each six-month offering period.  On November 29, 2005 we amended the ESPP Plan to provide that eligible employees may purchase common stock at a price equal to 95% of the fair market value of the common stock as of the end of each six-month offering period.  There is no stock-based compensation expense related to our Employee Stock Purchase Plan because it is not considered a compensatory plan. The plan does not have a look-back feature, and has a minimal discount of 5% of the fair market value of the common stock as of the end of each six-month offering period.  Participation in the ESPP Plan is limited to 6% of an employee’s compensation, may be terminated at any time by the employee and automatically ends on termination of employment.  A total of 350,000 shares of common stock have been reserved for issuance.  As of December 31, 2013 there were 108,959 shares available for future issuance under the ESPP Plan.  We issued 7,196, 4,661, and 5,563 common shares under the ESPP Plan in 2013, 2012, and 2011, respectively.
Dividends - In April 2012, our board of directors declared a special cash dividend of $1.15 per share. The dividend was paid on May 25, 2012 to shareholders of record as of May 11, 2012.  The total amount of the dividend paid was $25.5 million.
In November 2012, our board of directors declared a second special cash dividend of $1.80 per share. The dividend was paid on December 17, 2012 to shareholders of record as of December 3, 2012.  The total amount of the dividend paid was $40.5 million.
Share Repurchases – In July 2011, we purchased 250,000 shares of our common stock at a price of $2.90 per share from a shareholder in a privately negotiated transaction.  In addition, we paid a broker commission of 4 cents per share in connection with the transaction.

	Lease Commitments – We own our principal office and research facility in Bedford, Massachusetts, which we have occupied since November 1997.  We also conducted a portion of our activities in a leased facility in California in 2011 and 2012. We terminated that lease in September 2012 by making a one-time payment of $15,000.
	Rental expense, including the cost of the 2012 termination buyout of the California lease, was approximately $0, $25,000, and $17,000 in 2013, 2012 and 2011, respectively.
	Litigation - There are no material pending legal proceedings to which we are a party or to which any of our properties are subject which, either individually or in the aggregate, are expected to have a material adverse effect on our business, financial position or results of operations.
	Guarantees and Indemnification Obligations – We enter into agreements in the ordinary course of business that require us: i) to perform under the terms of the contracts, ii) to protect the confidentiality of our customers’ intellectual property, and iii) to indemnify customers, including indemnification against third party claims alleging infringement of intellectual property rights.  We also have agreements with each of our directors and executive officers to indemnify such directors or executive officers, to the extent legally permissible, against all liabilities reasonably incurred in connection with any action in which such individual may be involved by reason of such individual being or having been a director or officer of the Company.
	Given the nature of the above obligations and agreements, we are unable to make a reasonable estimate of the maximum potential amount that we could be required to pay.  Historically, we have not made any significant payments on the above guarantees and indemnifications and no amount has been accrued in the accompanying consolidated financial statements with respect to these guarantees and indemnifications.

OFF-BALANCE SHEET ARRANGEMENTS	'
	13.      OFF-BALANCE SHEET ARRANGEMENTS
	We do not currently have any arrangements with unconsolidated entities, such as entities often referred to as structured finance, special purpose entities, or variable interest entities which are often established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.  Accordingly, we are not exposed to any financing, liquidity, market or credit risk if we had such relationships.
	During 2011 and 2012 we disclosed that we had a patent arrangement with an unaffiliated third party that we classified as a variable interest entity.  We also disclosed that: i) we had no equity interest in this entity; ii) we were not contractually obligated to fund this entity, therefore our maximum exposure to loss as a result of our involvement with this entity was zero; iii) we may receive royalties in the future if certain conditions are met; iv) we were not the primary beneficiary of this entity; v) we have not consolidated this entity’s results into our financial statements, therefore we carried the assets and liabilities of this entity in our balance sheet at zero; and vi) prior to September 30, 2012, this arrangement had no impact on our results of operations, financial position or cash flows in any previous periods.
	In August 2012, certain contractual provisions of the arrangement were amended.  As a result, the arrangement was no longer considered a variable interest entity under generally accepted accounting principles, and we ceased to classify it as such once the amendment was signed.

SUMMARY_OF_SIGNIFICANT_ACCOUNT1

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation - The consolidated financial statements include the accounts of Aware, Inc. and its subsidiary.  All significant intercompany transactions have been eliminated.
Use of Estimates	'
	Use of Estimates – The preparation of our financial statements in conformity with accounting principles generally accepted in the United States of America requires us 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 amount of revenues and expenses during the reporting period.  The most significant estimates included in the financial statements pertain to revenue recognition, reserves for doubtful accounts, useful lives of fixed assets, valuation allowance for deferred income tax assets, and accrued liabilities.  Actual results could differ from those estimates.
Fair Value Measurements	'
	Fair Value Measurements - The Financial Accounting Standards Board (“FASB”) Codification defines fair value, and establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to the unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under the FASB Codification are: i) Level 1 – valuations that are based on quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date; ii) Level 2 – valuations that are based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly; and iii) Level 3 – valuations that require inputs that are both significant to the fair value measurement and unobservable.
	Cash and cash equivalents, which primarily include money market mutual funds, were $72.7 million and $71.1 million as of December 31, 2013 and December 31, 2012, respectively. We classified our cash equivalents of $68.6 million and $67.1 million as of December 31, 2013 and 2012, respectively, within Level 1 of the fair value hierarchy because they are valued using quoted market prices.
	Our investments, which consist of high yield corporate debt securities, are also classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. We categorize our investments as available-for-sale securities, and carry them at fair value in our financial statements.  We had $2.8 million and $2.0 million of available-for-sale investments as of December 31, 2013 and December 31, 2012, respectively.
	As of December 31, 2013, our assets that are measured at fair value on a recurring basis and whose carrying values approximate their respective fair values include the following (in thousands):
			Fair Value Measurement at December 31, 2013 Using:
			Quoted Prices in		Significant Other		Significant
			Active Markets for		Observable Inputs		Unobservable
			Identical Assets				Inputs
			(Level 1)		(Level 2)		(Level 3)
	Corporate debt securities		$	2,754	$	-	$	-
	Money market funds (included in cash and cash equivalents)			68,556
	Total		$	71,310	$	-	$	-
	As of December 31, 2012, our assets that are measured at fair value on a recurring basis and whose carrying values approximate their respective fair values include the following (in thousands):
			Fair Value Measurement at December 31, 2012 Using:
			Quoted Prices in		Significant Other		Significant
			Active Markets for		Observable Inputs		Unobservable
			Identical Assets				Inputs
			(Level 1)		(Level 2)		(Level 3)
	Corporate debt securities		$	2,010	$	-	$	-
	Money market funds (included in cash and cash equivalents)			67,050
	Total		$	69,060	$	-	$	-
Cash and Cash Equivalents	'
	Cash and Cash Equivalents – Cash and cash equivalents, which consist primarily of money market funds and demand deposits, are stated at fair value. All highly liquid investments purchased with an original maturity of three months or less are considered cash equivalents. Our cash balances exceed the Federal Deposit Insurance Corporation limits. The Company does not believe it is exposed to significant credit risk related to cash and cash equivalents.
Investments	'
	Investments - At December 31, 2013 and 2012, we categorized all investment securities as available-for-sale, since we may liquidate these investments currently.  In calculating realized gains and losses, cost is determined using specific identification. Unrealized gains and losses on available-for-sale securities are excluded from earnings and reported in a separate component of stockholders’ equity called Accumulated Comprehensive Income.
	Realized gains on investments were $23,000 and $85,000 in the years ended December 31, 2013 and 2012, respectively.  There were no realized gains or losses on investments in the year ended December 31, 2011.
	Unrealized losses on investments were $156,000, $30,000, and $20,000 in the years ended December 31, 2013, 2012, and 2011.
	The amortized cost of our corporate debt securities was $3.0 million at December 31, 2013. Corporate debt securities comprising investments mature in 2015 to 2018.
Allowance for Doubtful Accounts	'
	Allowance for Doubtful Accounts – Accounts are charged to the allowance for doubtful accounts as they are deemed uncollectible based on a periodic review of the accounts.
Inventories	'
	Inventories – Inventories are stated at the lower of cost or net realizable value. Cost is determined by the first-in, first-out (“FIFO”) method.  We evaluate all inventories for net realizable value on a quarterly basis, and record provisions for excess and obsolete inventory when required.  There was no reserve for excess and obsolete inventory as of December 31, 2013.
Property and Equipment	'
	Property and Equipment – Property and equipment is stated at cost.  Depreciation and amortization of property and equipment is provided using the straight-line method over the estimated useful lives of the assets. Upon retirement or sale, the costs of the assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss on disposal is included in the determination of income or loss.  Expenditures for repairs and maintenance are charged to expense as incurred.
	The estimated useful lives of assets used by us are:
		Building	30 years
		Building improvements	5 to 20 years
		Furniture and fixtures	5 years
		Computer, office & manufacturing equipment	3 years
		Purchased software	3 years
Impairment of Long-Lived Assets	'
	Impairment of Long-Lived Assets – We review long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate.  Each impairment test is based on a comparison of the undiscounted cash flows estimated to be generated by those assets over their estimated economic life to the related carrying value of those assets to determine if the assets are impaired. If an impairment is indicated, the asset is written down to its estimated fair value.  The cash flow estimates used to identify the potential impairment reflect our best estimates using appropriate assumptions and projections at that time.  We believe that no significant impairment of our long-lived assets has occurred as of December 31, 2013 and 2012.
Revenue Recognition	'
	Revenue Recognition – We recognize revenue when there is persuasive evidence of an arrangement, the sales price is fixed or determinable, collection of the related receivable is reasonably assured, and delivery has occurred or services have been rendered.
	Persuasive evidence of an arrangement: We use contracts signed by both the customer and us or written purchase orders issued by the customer as evidence of an arrangement.
	Product delivery: We deem delivery to have occurred: (i) upon shipment when products are shipped FOB shipping point, or (ii) upon delivery at a customer’s location when products are shipped FOB destination, or (iii) when software is delivered electronically.  If customer acceptance provisions apply, revenue is not recognized until delivery has occurred and we have received such acceptance. If we are required to provide installation services, revenue is not recognized until installation is complete.
	Fixed or determinable fee: We consider fees to be fixed or determinable if the fee is not subject to refund or adjustment and the payment terms are within normal established practices. If the fee is not fixed or determinable, we recognize the revenue as amounts become due and payable.
	Collection is deemed probable: We conduct a credit review for significant transactions at the time of the arrangement to determine the credit-worthiness of the customer. Collection is deemed probable if we expect that the customer will pay amounts under the arrangement as payments become due.
	We categorize revenue as software licenses, software maintenance, services, hardware sales, or royalties. In addition to the general revenue recognition policies described above, specific revenue recognition policies apply to each category of revenue.
	Software licenses
	Software licenses consist of revenue from the sale of software licenses for biometrics and imaging applications.  We recognize revenue from software licenses upon delivery when licenses are sold in single element arrangements.
	Software maintenance
	Software maintenance consists of revenue from the sale of software maintenance contracts for biometrics and imaging software.  Software maintenance contracts entitle customers to receive software support and software updates, if and when they become available, during the term of the maintenance contract. We recognize software maintenance revenue ratably over the related contract period.
	Services
	Service revenue consists of fees from biometrics customers for engineering services we provide to them. We recognize services revenue as services are delivered when services are sold in single element arrangements.
	Hardware sales
	Hardware sales consist of sales of biometrics equipment to a single U.S. government customer.  We recognize hardware sales upon delivery and acceptance of the equipment by the customer.
	Royalties
	Royalty revenue consists of royalties we receive under DSL silicon IP contracts with customers that have incorporated our intellectual property into their products. Since we cannot reasonably estimate royalty revenue, such revenue is recognized in the quarter in which a final report is received from a customer. Royalty reports are typically received in the quarter immediately following the quarter in which sales of royalty-bearing products occur.
	Multiple element arrangements
	In addition to selling software licenses, software maintenance and services in single element arrangements, we also sell these three products and hardware as part of multiple element arrangements.  The various combinations of multiple element arrangements and our revenue recognition for each are described as follows:
		●	Software licenses and software maintenance. When software licenses and software maintenance contracts are sold together, we recognize software license revenue upon delivery, provided we have vendor specific objective evidence (“VSOE”) for the fair value of the maintenance contract fee, and we recognize the fair value of maintenance contract revenue ratably over the related contract period.
		●	Software licenses and services. When software licenses and engineering services are sold together, the total fee is generally recognized by applying contract accounting. We have adopted the percentage-of-completion method of contract accounting, and we generally use an input method (i.e., labor hours) to determine our completion percentage. The software license portion of the arrangement is classified as software license revenue and the engineering services portion is classified as services revenue.
		●	Software licenses, software maintenance and services. When we sell software licenses, software maintenance and services together, revenue is recognized as follows: i) software maintenance revenue is separated from the other two elements and is recognized ratably over the related software maintenance contract period; provided we have VSOE for the fair value of the maintenance element; and ii) the total fee from the software license and engineering service elements is recognized by applying the contract accounting method described in the previous paragraph.
		●	Hardware sales, software maintenance, and services. We have a multiple element arrangement with one customer that involves the delivery of hardware, maintenance, and services.  We determined that these elements qualified as separate units of accounting because they have value to the customer on a standalone basis.  We recognize revenue from this arrangement as follows: i) hardware revenue is recognized upon delivery and acceptance of the equipment by the customer; ii) maintenance revenue is recognized ratably over the related contract period; and iii) service revenue is recognized as services are delivered.
Income Taxes	'
	Income Taxes – We compute deferred income taxes based on the differences between the financial statement and tax basis of assets and liabilities using enacted rates in effect in the years in which the differences are expected to reverse.  We establish a valuation allowance to offset temporary deductible differences, net operating loss carryforwards and tax credits when it is more likely than not that the deferred tax assets will not be realized.
	We recognize the tax benefit from an uncertain tax position only if it is more-likely-than-not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the tax position. The evaluation of an uncertain tax position is based on factors that include, but are not limited to, changes in the tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, and changes in facts or circumstances related to a tax position.  Any changes to these estimates, based on the actual results obtained and/or a change in assumptions, could impact our tax provision in future periods.  Interest and penalty charges, if any, related to unrecognized tax benefits would be classified as a provision for income tax in the statement of income.
Capitalization of Software Costs	'
	Capitalization of Software Costs – We capitalize certain internally developed software development costs after technological feasibility of the product has been established.  No software costs were capitalized for the years ended December 31, 2013, 2012 and 2011, because such costs incurred subsequent to the establishment of technological feasibility, but prior to commercial availability, were immaterial.
Research and Development Costs	'
	Research and Development Costs – Costs incurred in the research and development of our products are expensed as incurred.
Concentration of Credit Risk	'
	Concentration of Credit Risk – At December 31, 2013 and 2012, we had cash and cash equivalents, in excess of federally insured deposit limits of approximately $72.4 million and $70.8 million, respectively.
	Concentration of credit risk with respect to net accounts receivable consisted of $2.7 million, $0.2 million, $0.2 million, $0.2 million and $0.2 million with five customers, respectively, at December 31, 2013, and $1.1 million, $0.6 million, $0.5 million, $0.4 million and $0.3 million with five customers, respectively, at December 31, 2012.
	Concentration of credit risk with respect to our investment portfolio consisted of $0.8 million, $0.5 million, $0.5 million, $0.5 million, and $0.4 million with five issuers of corporate debt securities, respectively, at December 31, 2013, and $1.0 million and $1.0 million with two issuers of corporate debt securities, respectively, at December 31, 2012.
Stock-Based Compensation	'
	Stock-Based Compensation – We grant stock options and stock to our employees and directors.  We measure stock-based compensation cost at the grant date based on the fair value of the award and recognize stock-based compensation expense on a straight-line basis over the requisite service period of the award.
	We use the Black-Scholes option valuation model to estimate the fair value of stock option awards. This valuation model takes into account the exercise price of the award, as well as a variety of significant assumptions.  The assumptions used to estimate the fair value of stock options include the expected term, the expected volatility of our stock over the expected term, the risk-free interest rate over the expected term, and our expected annual dividend yield.
	For stock awards, we determine the fair value of the award by using the fair market value of our stock on the date of grant; provided the number of shares in the grant is fixed on the grant date.
Computation of Earnings per Share	'
	Computation of Earnings per Share – Basic earnings per share is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding.  Diluted earnings per share is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding plus additional common shares that would have been outstanding if dilutive potential common shares had been issued.  For the purposes of this calculation, stock options are considered common stock equivalents in periods in which they have a dilutive effect.  Stock options that are antidilutive are excluded from the calculation.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments – The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value because of their short-term nature. The carrying amount of investments is based on the fair value of the individual securities in our investment portfolio.
Advertising Costs	'
	Advertising Costs – Advertising costs are expensed as incurred and were not material for 2013, 2012, and 2011.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements – There were no recently issued accounting pronouncements applicable to us that we had not adopted as of December 31, 2013.
Reclassifications	'
	Reclassifications - Certain prior period amounts have been reclassified to be consistent with the current period presentation, particularly as a result of the discontinued operations presentation of our DSL service assurance business. See Note 4 to the Consolidated Financial Statements.
Segments	'
	Segments – Following the shutdown of our DSL Service Assurance Segment as described in Note 4, we organize ourselves into a single segment reporting to the chief operating decision makers. We have sales outside of the United States, which are described in Note 10.  All long-lived assets are maintained in the United States.
