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 (“the Company”). 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, valuation of acquired assets and assumed liabilities in business combinations and valuation allowance for deferred income tax assets. 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 $38.6 million and $47.7 million at December 31, 2020 and December 31, 2019, respectively. We classified our cash equivalents of $37.9 million and $46.2 million as of December 31, 2020 and 2019, respectively, within Level 1 of the fair value hierarchy because they are valued using quoted market prices. Our cash equivalents are measured at fair value on a recurring basis and their carrying values approximate their respective fair values.

As of December 31, 2020, 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, 2020 Using:
	Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs
	(Level 1)		(Level 2)		(Level 3)
Money market funds (included in cash and cash equivalents)	$	37,948	$	-	$	-
Total	$	37,948	$	-	$	-

As of December 31, 2019, 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, 2019 Using:
	Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs
	(Level 1)		(Level 2)		(Level 3)
Money market funds (included in cash and cash equivalents)	$	46,174	$	-	$	-
Total	$	46,174	$	-	$	-

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.

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.

For the years ended December 31, 2020 and 2019, changes to and ending balances of the allowance for doubtful accounts were as follows (in thousands):

	Years ended December 31,
	2020		2019
Allowance for doubtful accounts balance - beginning of year	$	20	$	20
Additions to the allowance for doubtful accounts		118		-
Deductions against the allowance for doubtful accounts		-		-
Allowance for doubtful accounts balance - end of year	$	138	$	20

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

Goodwill – We record goodwill when consideration paid in a business acquisition exceeds the value of the net assets acquired. Our estimates of fair value are based upon assumptions believed to be reasonable at the time, but such estimates are inherently uncertain and unpredictable. Assumptions may be incomplete or inaccurate and unanticipated events or circumstances may occur, which may affect the accuracy of validity of such assumptions, estimates or actual results. Goodwill is not amortized but rather is tested for impairment annually in the fourth quarter or more frequently, if facts and circumstances warrant a review. Circumstances that could trigger an impairment test include, but are not limited to, a significant adverse change in the business climate or legal factors, an adverse action or assessment by a regulator, or unanticipated competition. We have determined that there is a single reporting unit for the purpose of conducting the goodwill impairment assessment. In accordance with ASC Topic 350, Intangibles—Goodwill and Other, we first assess qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. If after assessing the totality of events or circumstances, we determine that it is more likely than not (i.e. greater than 50% likelihood) that the fair value of the reporting unit is less than its carrying amount, then the quantitative test is required. The quantitative goodwill impairment test requires us to estimate and compare the fair value of the reporting unit, determined using an income approach and a market approach, with its carrying value. If the fair value of the reporting unit exceeds the carrying value of the net assets, goodwill is not impaired. If the fair value of the reporting unit is less than the carrying value, the difference is recorded as an impairment loss up to the amount of goodwill.

Application of the goodwill impairment test requires judgments, including identification of the reporting units, assigning goodwill to reporting units, a qualitative assessment to determine whether there are any impairment indicators, and determining the fair value of each reporting unit which often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, asset lives and market multiples, among other items. There is no assurance that the actual future earnings or cash flows of the reporting unit will not decline significantly from the projections used in the impairment analysis. Goodwill impairment charges may be recognized in future periods to the extent changes in factors or circumstances occur, including deterioration in the macroeconomic environment and industry, deterioration in the Company’s performance or its future projections, or changes in plans for its reporting unit.

As of December 31, 2020, we had $1.7 million of goodwill. Changes in the valuation of goodwill could materially impact our operating results and financial position. To date, there have been no impairments of goodwill.

Valuation 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. In evaluating potential impairment of these assets, we specifically consider whether any indicators of impairment are present, including, but not limited to:

•

whether there has been a significant adverse change in the business climate that affects the value of an asset:

•

whether there has been a significant change in the extent or way an asset is used; and

•

whether there is an expectation that the asset will be sold or disposed of before the end of its originally estimated useful life.

We did not identify any events or changes in business circumstances that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate during the year ended December 31, 2020.

Revenue recognition. The core principle of Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”) is that we should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. To achieve that core principle, we should apply the following five step model:

1) Identify the contract with the customer

A contract with a customer exists when (i) we enter into an enforceable contract with a customer that defines each party’s rights regarding the goods or services to be transferred and identifies the related payment terms, (ii) the contract has commercial substance, and (iii) we determine that collection of substantially all consideration for goods and services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. We apply judgment in determining the customer’s intent and ability to pay, which is based on a variety of factors including the customer’s historical payment experience, or in the case of a new customer, published credit and financial information pertaining to the customer.

We evaluate contract modifications for the impact on revenue recognition if they have been approved by both parties such that the enforceable rights and obligations under the contract have changed. Contract modifications are either accounted for using a cumulative effect adjustment or prospectively over the remaining term of the arrangement. The determination of which method is more appropriate depends on the nature of the modification, which we evaluate on a case-by-case basis.

We combine two or more contracts entered into at or near the same time with the same customer and account for them as a single contract if (i) the contracts are negotiated as a package with a common commercial objective, (ii) the amount of consideration to be paid in one contract depends on the price or performance of the other contract, or (iii) some or all of the goods or services in one contract would be combined with some or all of the goods and services in the other contract into a single performance obligation. If two or more contracts are combined, the consideration to be paid is aggregated and allocated to the individual performance obligations without regard to the consideration specified in the individual contracts.

2) Identify the performance obligations in the contract

Performance obligations promised in a contract are identified based on the goods and services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the good or service either on its own or together with other available resources, and are distinct in the context of the contract, whereby the transfer of the good or service is separately identifiable from other promises in the contract. To the extent a contract includes multiple promised goods and services, we apply judgment to determine whether promised goods and services are capable of being distinct and distinct in the context of the contract. If these criteria are not met, the promised goods and services are accounted for as a combined performance obligation. To identify performance obligations, we consider all of the goods or services promised in a contract regardless of whether they are explicitly stated or are implied by customary business practices.

3) Determine the transaction price

The transaction price is determined based on the consideration we expect to be entitled in exchange for transferring promised goods and services to the customer. Determining the transaction price requires significant judgment. To the extent the transaction price includes variable consideration, we estimate the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in our judgment, it is probable that a significant future reversal of cumulative revenue recognized under the contract will not occur. Any estimates, including the effect of the constraint on variable consideration, are evaluated at each reporting period. Some of our arrangements include usage-based royalties where a software license is the predominant item that the royalty relates to. In these arrangements, revenue from the usage-based royalty is recognized when the subsequent usage occurs.

The amount of consideration is not adjusted for a significant financing component if the time between payment and the transfer of the related good or service is expected to be one year or less under the practical expedient in ASC 606-10-32-18. Our revenue arrangements are typically accounted for under such expedient, as payment is typically due within 30 to 60 days. As of December 31, 2020 and 2019, none of our contracts contained a significant financing component.

4) Allocate the transaction price to performance obligations in the contract

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price (“SSP”) basis unless the transaction price is variable and meets the criteria to be allocated entirely to a performance obligation or to a distinct service that forms part of a single performance obligation. The consideration to be received is allocated among the separate performance obligations based on relative SSPs. The SSP is the price at which we would sell a promised good or service separately to a customer. The best estimate of SSP is the observable price of a good or service when we sell that good or service separately. A contractually stated price or a list price for a good or service may be the SSP of that good or service. We use a range of amounts to estimate SSP when we sell each of the goods and services separately and need to determine whether there is a discount that needs to be allocated based on the relative SSP of the various goods and services. In instances where SSP is not directly observable, such as when we do not sell the product or service separately, we typically determine the SSP using an adjusted market assessment approach using information that may include market conditions and other observable inputs. We typically have more than one SSP for individual goods and services due to the stratification of those goods and services by customers and circumstances. In these instances, we may use information such as the nature of the customer and distribution channel in determining the SSP.

5) Recognize revenue when or as we satisfy a performance obligation

We satisfy performance obligations either over time or at a point in time. Revenue is recognized over time if 1) the customer simultaneously receives and consumes the benefits provided by our performance, 2) our performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or 3) our performance does not create an asset with an alternative use to us and we have an enforceable right to payment for performance completed to date. If we do not satisfy a performance obligation over time, the related performance obligation is satisfied at a point in time by transferring the control of a promised good or service to a customer.

We categorize revenue as software licenses, software maintenance, or services. 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. Our software licenses are functional intellectual property and typically provide customers with the right to use our software on a term or perpetual basis as it exists when made available to the customer. We recognize revenue from perpetual software licenses at a point in time upon delivery, provided all other revenue recognition criteria are met.

We also offer certain products pursuant to a usage based software model which includes a term software license to use the software for a fixed term. We recognize revenue for fixed fees associated with usage based software licenses at a point in time upon delivery, provided all other revenue recognition criteria are met. Fees subject to the usage-based royalty exception are recognized when the subsequent usage occurs.

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. Software support and software updates are considered distinct services. However, these distinct services are considered a single performance obligation consisting of a series of distinct services that are substantially the same and have the same pattern of transfer to the customer. We recognize software maintenance revenue over time on a straight-line basis over the contract period.

Services

Service revenue consists of fees from biometrics customers for software engineering services we provide to them. We recognize services revenue over time as the services are delivered using an input method (i.e., labor hours incurred as a percentage of total labor hours budgeted), provided all other revenue recognition criteria are met. The use of the over-time revenue recognition method requires judgment in developing budgeted labor hours. Changes in budgeted hours may occur and the resulting impact on revenue recognition is accounted for in the period of the change in estimate.

Arrangements with multiple performance obligations

In addition to selling software licenses, software maintenance and software services on a standalone basis, a significant portion of our contracts include multiple performance obligations. The various combinations of multiple performance obligations and our revenue recognition for each are described as follows:

•

Perpetual software licenses and software maintenance. When software licenses and software maintenance contracts are sold together, the software licenses and software maintenance are generally considered distinct performance obligations. The transaction price is allocated to the software licenses and the software maintenance based on relative SSP. Revenue allocated to the software licenses is recognized at a point in time upon delivery, provided all other revenue recognition criteria are met. Revenue allocated to the software maintenance is recognized over time on a straight-line basis over the contract period.

•

Perpetual software licenses and services. When software licenses and significant customization engineering services are sold together, they are accounted for as a combined performance obligation, as the software licenses are generally highly dependent on, and interrelated with, the associated services and therefore are not distinct performance obligations. Revenue for the combined performance obligation is recognized over time as the services are delivered using an input method (i.e., labor hours incurred as a percentage of total labor hours budgeted). When software licenses and standard implementation or consulting-type services are sold together, they are generally considered distinct performance obligations, as the software licenses are not dependent on or interrelated with the associated services. The transaction price in these arrangements is allocated to the software licenses and services based on relative SSP. Revenue allocated to the software licenses is recognized at a point in time upon delivery, provided all other revenue recognition criteria are met. Revenue allocated to the services is recognized over time using an input method. In arrangements with both software licenses and services, the software license portion of the arrangement is classified as software license revenue and the services portion is classified as services revenue in our consolidated statements of operations.

•

Perpetual software licenses, software maintenance and services. When we sell software licenses, software maintenance and software services together, we account for the individual performance obligations separately if they are distinct. The transaction price is allocated to the separate performance obligations based on relative SSP. Revenue allocated to the software licenses is recognized at a point in time upon delivery. Revenue allocated to the services is recognized over time using an input method (i.e., labor hours incurred as a percentage of total labor hours budgeted). Revenue for the software maintenance is recognized over time on a straight-line basis over the contract period. However, if the software services are significant customization engineering services, they are accounted for with the software licenses as a combined performance obligation, as stated above. Revenue for the combined performance obligation is recognized over time using an input method.

•

Usage based software licenses consisting of a term software license and software maintenance. When usage based software subscription licenses are sold, the term software license and software maintenance are generally considered distinct performance obligations. The transaction price is allocated to term software license and the software maintenance based on relative SSP. We sell usage based software license for a fixed fee and/or a usage-based royalty fee, sometimes subject to a minimum guarantee. When the amount is in the form of a fixed fee, including the guaranteed minimum in usage based royalty, revenue is allocated to the term software license recognized at a point in time upon delivery, provided all other revenue recognition criteria are met. Any royalties not subject to the guaranteed minimum or earned in excess of the minimum amount are recognized as revenue when the subsequent usage occurs. Revenue allocated to the software maintenance is recognized over the contract term time on a straight-line basis over the contract period.

Returns

We do not offer rights of return for our products and services in the normal course of business.

Customer Acceptance

Our contracts with customers generally do not include customer acceptance clauses.

Contract Balances

When the timing of our delivery of goods or services is different from the timing of payments made by customers, we recognize either a contract asset (performance precedes contractual due date) or a contract liability (customer payment precedes performance). Customers that prepay are represented by the deferred revenue below until the performance obligation is satisfied. Our contract assets consist of unbilled receivables. Our contract liabilities consisted of deferred (unearned) revenue, which is generally related to software maintenance contracts. We classify deferred revenue as current or noncurrent based on the timing of when we expect to recognize revenue.

The following table presents changes in our contract assets and liabilities during the years ended December 31, 2019 and 2020 (in thousands):

Remaining Performance Obligations

Remaining performance obligations represent the transaction price from contracts for which work has not been performed or goods and services have not been delivered. We expect to recognize revenue on approximately 67% of the remaining performance obligations over the next 12 months, with the remainder recognized thereafter. As of December 31, 2020, the aggregate amount of the transaction price allocated to remaining performance obligations with a duration greater than one year, comprised of software maintenance contracts, was $2.4 million.

Contract Costs

We recognize an other asset for the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. We have determined that certain sales commissions meet the requirements to be capitalized, and we amortize these costs on a consistent basis with the pattern of transfer of the goods and services in the contract. Total capitalized costs to obtain a contract were immaterial during the periods presented and are included in other current and long-term assets on our consolidated balance sheets.

We apply a practical expedient to expense costs as incurred for costs to obtain a contract when the amortization period is one year or less. These costs include sales commissions on software maintenance contracts with a contract period of one year or less as sales commissions paid on contract renewals are commensurate with those paid on the initial contract.

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 consolidated statements of operations.

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 during the years ended December 31, 2020 and 2019, 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, 2020 and 2019, we had cash and cash equivalents, in excess of federally insured deposit limits of approximately $38.3 million and $47.5 million, respectively.

Concentration of credit risk with respect to net accounts receivable and unbilled receivables consisted of amounts owed by the following customers that comprised more than 10% of net accounts receivable and unbilled receivables at December 31:

Customer A		39	%		72	%

Stock-Based Compensation – We grant stock and stock options 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.

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.

For stock options, we use the Black-Scholes option valuation model to estimate the fair value of the award. 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.

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.

Segments – We organize ourselves into a single segment reporting to the chief operating decision maker. We have sales outside of the United States. All long-lived assets are maintained in the United States.

We conduct our operations in the United States and sell our products and services to domestic and international customers. Revenues were generated from the following geographic regions (in thousands):

Acquisitions

4.	ACQUISTIONS

In November 2020, the Company entered into a Bill of Sale and Assignment Agreement (the “Agreement”) with Radiant Mission Solutions Inc. (“Radiant” as seller) and Maxar Technologies, Inc. (as guarantor) to acquire certain assets and assume certain liabilities of Radiant’s AFIX product line for cash consideration of approximately $2.4 million. The acquisition of AFIX, provides turnkey face and fingerprint biometric and forensic analysis software for small and medium-sized law enforcement and government agencies, extends our ABIS product family.

The acquisition was accounted for as a business combination, whereby all the assets acquired, and liabilities assumed were recognized at fair value on the acquisition date, with any excess of the consideration transfer over the fair value of the net assets acquired recognized as goodwill. Unaudited pro forma results of operations assuming the above acquisition had taken pace at the beginning of each period are not provided because the historical operating results and pro forma results would not be materially different from reported results for the periods presented.

The preliminary fair values recorded were based on a preliminary valuation and the estimates and assumptions used in such valuation are subject to change, within the measurement period (up to one year from the acquisition date). The Company is continuing to obtain information to determine the acquired assets and liabilities, including tax, assets, liabilities and other assets. The following table summarizes the preliminary fair values of the assets acquired and liabilities assumed at the date of acquisition (in thousands):

Net working capital, excluding deferred revenue	$	155
Customer relationships		940
Developed technology		280
Trade name / trademarks		20
Goodwill		1,651
Gross assets acquired		3,046
Deferred revenue		(616	)
Net assets acquired	$	2,430

After allocating the purchase price to the assets acquired and liabilities assumed based on their fair values at the date of acquisition, the Company recorded goodwill of approximately $1.7 million. Goodwill largely consists of expected synergies to be realized from combining operations. The goodwill is deductible for income tax purposes.

The fair values of intangible assets were based on valuations using the income approach. The preliminary fair value of intangible assets and their estimated useful live are as follows (dollars in thousands):

	Useful Life	Gross Amount		Accumulated Amortization		Net Book Value
Customer relationships	8 years	$	940	$	15	$	925
Developed technology	5 years	280		7		273
Tradenames	7 years	20		1		19
		$	1,240	$	23	$	1,217

During the year ended December 31, 2020 we recorded $23 thousand of amortization for its intangibles. The Company expects to record amortization for the years ended December 31 (in thousands):

5.	INCOME TAXES

We recorded a benefit for income taxes of $1.6 million in the year ended December 31, 2020 that includes a $1.4 million tax benefit of the current year tax loss which can be carried back due to changes made by the Coronavirus Aid, Relief and Economic Security Act (CARES Act) which was signed into law on March 27, 2020. The CARES Act contained specific relief and stimulus measures including allowing net operating losses originating in 2018 through 2020 to be carried back five years to offset taxable income in the carryback period. We recorded a provision for income taxes of $5.2 million in the year ended December 31, 2019. The components of the provision for income taxes are as follows (in thousands):

	Year ended December 31,
	2020			2019
Current:
Federal		(1,397	)		8
State		(237	)		32

Federal		—			4,965
State		—			206
		—			5,171
Provision for (benefit from) income taxes	$	(1,634	)	$	5,211

A reconciliation of the U.S. federal statutory rate to the effective tax rate is as follows:

	Year ended December 31,
	2020			2019
Federal statutory rate		21	%		21	%
State rate, net of federal benefit		6			6
Tax credits		3			10
Permanent adjustments		—			(1	)
Change in valuation allowance		(25	)		(202	)
Expiration of statutes on uncertain tax positions		2			—
Net operating loss carryback rate benefit under CARES Act		11			—
Other		—			(1	)
Effective tax rate		18	%		(167	)%

The 2020 difference between the effective tax rate and the U.S federal statutory rates was driven primarily due to the change in valuation allowance of our deferred tax assets. This was partially offset by an income tax rate benefit related to a carryback of the 2020 net operating losses under the CARES Act.

The 2019 difference between the effective tax rate and the U.S federal statutory rates was driven primarily due to the change in valuation allowance of our deferred tax assets.

We had deferred tax assets of $8.7 million and $6.3 million as of December 31, 2020 and 2019 respectively. The principal components of deferred tax assets were as follows at December 31 (in thousands):

	2020			2019
Depreciation	$	307		$	354
Stock compensation		121			115
Research and development credits		6,686			4,975

Total		8,674			6,325
Less valuation allowance		(8,674	)		(6,325	)
Deferred tax assets, net	$	—		$	—

As of December 31, 2020, $6.7 million of our deferred tax assets relates to research credit carryforwards. We have assessed the need for a valuation allowance on our deferred tax assets. We evaluated and considered all available evidence, both positive and negative, to determine whether, based on the weight of that evidence, a valuation allowance for deferred tax assets was needed. As part of this analysis, we have given more weight to recent, historical evidence than future projections as we consider the past more objective. As of the fourth quarter of 2020, we have a cumulative pretax loss over the most recent three-year period including a pretax loss of $9.2 million in 2020. We considered the cumulative loss as of the end of the fourth quarter of 2020 to be significant negative evidence in the overall analysis.

In 2019, we appointed a new Chief Executive Officer and, as a result, we reviewed and made changes to our strategy and business plans. We will be making additional investments in research, product development and sales and marketing including additional headcount. These changes in strategy and additional investment started in 2019 and continued in 2020. Our pretax income forecasts are highly predicated upon new product development and penetrating new markets. Therefore, this evidence is given nominal weight in the analysis compared to the recent history of losses and anticipated investment.

Further, a significant portion of our deferred tax assets relates to federal and state research and development credits. These credits may only offset 75% of the tax liability after net operating loss carryforwards are utilized and thus, we have the risk that the credits could expire before utilization if sufficient taxable income in the carryforward periods doesn’t exist.

Based upon the information available to us at the time, the above analysis of evidence represents our best estimate regarding the utilization of the deferred tax assets, and we concluded as of December 31,2019 that it is more likely than not that the deferred tax assets will not be realized. Therefore, we have recorded a full valuation allowance of $6.3 million against our deferred tax assets as of December 2019. We have also concluded that as of December 31, 2020 it is more likely than not that the deferred tax assets will not be realized. Therefore, we have recorded a full valuation allowance for a total of $8.7 million as of December 31, 2020. We will continue to monitor the evidence and the realizability of our deferred tax assets in future periods. Should evidence regarding the realizability of our deferred tax assets change at a future point in time, we will adjust the valuation allowance as required.

A roll forward of the uncertain tax position that was primarily related to our research and development tax credits is as follows (in thousands):

Uncertain tax positions at December 31, 2018	$	998
Increase due to positions taken in prior periods		10
Uncertain tax positions at December 31, 2019		1,008
Decrease due to positions taken in prior periods		(206	)
Uncertain tax positions at December 31, 2020	$	802

Uncertain tax positions of $0.8 million will impact our tax rate if realized.

The tax years from 2017 through 2020 are subject to examination by the IRS and the tax years 2004 through 2020 are subject to examination by state tax authorities.

Equity and Stock Compensation Plans

6.	EQUITY AND STOCK COMPENSATION PLANS

Stock Option Plan – We have one active fixed stock option plan which is 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 under this plan. As of December 31, 2020, there were 3,760,815 shares available for grant under the 2001 Plan.

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. Options generally vest over three to five years.

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,
	2020		2019
Cost of services	$	17	$	18
Research and development		188		117
Selling and marketing		168		57
General and administrative		465		500
Stock-based compensation expense	$	838	$	692

Stock-based compensation expense in the preceding table includes expenses associated with grants of: i) stock options, ii) unrestricted shares of our common stock; and iii) performance share awards. The methods used to determine stock-based compensation expense for each type of equity grant are described in the following paragraphs.

Stock Option Grants. For the years ended December 31, 2020 and 2019, we granted stock options for 50,000 and 435,000 shares of our common stock, respectively. We estimate the fair value of those stock options 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 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 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. 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, 2020. 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 year ended December 31, 2020, using the Black-Scholes valuation model were:

	Years ended December 31,
	2020			2019
Expected term (1)	6.14 years			6.08-6.18 years
Expected volatility factor (2)		37	%	35-46%
Risk-free interest rate (3)		0.6	%	1.51-1.66%
Expected annual dividend yield	n/a			n/a

(1) The expected term for each grant was determined based on the simplified method.

(2) The expected volatility for each grant is estimated based on an average of historical volatility over the expected term of the stock options.

(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.

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 256,250, and 285,500 shares of unrestricted stock during the years ended December 31, 2020, and 2019, respectively.

The accounting treatment of unrestricted stock awards in 2020 and 2019 is described below:

In 2020, we granted 256,250 shares of unrestricted stock to directors, officers, and employees. In March and May 2020, we granted 243,000 shares of unrestricted stock to directors, officers, and employees. The shares were issued in two equal installments shortly after June 30, 2020 and December 31, 2020. In October and November, we granted 13,250 shares of unrestricted stock to employees. The shares were issued shortly after December 31, 2020.

We expensed $0.7 million of stock-based compensation expense related to these grants in the year ended December 31, 2020. There was no unamortized stock-based compensation charge associated with these stock grants as of December 31, 2020.

We issued 109,773 shares of common stock related to the March and May 2020 grants in early July 2020 after employees surrendered 11,727 shares for which we paid $75,000 of withholding taxes on their behalf.

In 2019 we granted 285,500 shares of unrestricted stock to directors, officers, and employees. We also, granted 120,000 shares to be issued in four equal installments on the anniversaries of their grant dates in September and October of 2020, 2021, 2022, and 2023, provided the grantee is serving as a director, officer, or employee on those dates. We also granted 165,500 shares throughout March, September, and October of 2019. We issued 71,500 and 94,000 shares shortly after September 30, 2019 and December 31, 2019, respectively. The total stock-based compensation expense related to the 285,500 shares granted in 2019 is $947,000, of which $633,000 was charged to expense in the 2019 and $122,000 was charged to expense in 2020. We anticipate the remaining $230,000 will be charged to expense ratably through 2023.

We issued shares of common stock related to the March 2019 grant as follows: i) 58,548 net shares of common stock were issued in early July 2019 after employees surrendered 12,952 shares for which we paid $43,000 of withholding taxes on their behalf; and ii) 56,605 net shares of common stock were issued in early January 2020 after employees surrendered 14,895 shares for which we paid $50,000 of withholding taxes on their behalf. We also issued 20,000 and 10,000 shares of common stock related to a September 2019 and October 2019 grant in September 2020 and October 2020 respectively.

Performance Share Award. In September 2019, we granted 20,000 shares of stock to an officer as a performance share award under our 2001 Nonqualified Stock Plan. The shares were issued in September 2019 and became fully vested on March 19, 2020 as the officer was still serving as a director, officer or employee, 2020. Stock-based compensation expense for this stock grant was determined based on the fair market value of our stock on the date of grant, as the number of shares in the grant was fixed on the grant date. The total stock-based compensation expense related to this grant was $55,000, of which $31,000 was charged to expense in 2019 and $24,000 was charged to expense in 2020.

In October 2019, we granted 10,000 shares of stock to an officer as a performance share award under our 2001 Nonqualified Stock Plan. The shares were issued in October 2019 and became full vested on April 1, 2020 as the officer was still serving as a director, officer or employee. Stock-based compensation expense for this stock grant was determined based on the fair market value of our stock on the date of grant, as the number of shares in the grant was fixed on the grant date. The total stock-based compensation expense related to this grant was $29,000, of which $15,000 was charged to expense in 2019 and $14,000 was charged to expense 2020.

A summary of stock option transactions for our fixed stock option plan for the years ended December 31, 2020, and 2019 are presented below:

	2020				2019
	Shares		Weighted Average Exercise Price		Shares		Weighted Average Exercise Price
Outstanding at beginning of year		435,000	$	6.00		18,000	$	2.52

Exercisable at year end		112,496	$	6.00		16,248	$	6.00

Total options outstanding at December 31, 2020 were 425,000. 112,496 of those options were vested and had a weighted average exercise price of $6.00.

Options to purchase up to 50,000 and 435,000 shares of our common stock were granted in the years ended December 31, 2020 and 2019 respectively.

At December 31, 2020, the weighted average remaining contractual term for total options outstanding and total options exercisable was approximately 8.83 and 8.78 years, respectively.

At December 31, 2020, the aggregate intrinsic value of options outstanding and options exercisable was zero. 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 following table summarizes the stock options outstanding at December 31, 2020:

	Options Outstanding						Options Exercisable
Exercise Price Range	Number		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (in years)		Number		Weighted Average Exercise Price
$4 to $5		106,250	$	4.50		8.8304		28,124	$	4.50
$5 to $6		106,250	$	5.50		8.8304		28,124	$	5.50
$6 to $7		106,250	$	6.50		8.8304		28,124	$	6.50
$7 to $8		106,250	$	7.50		8.8304		28,124	$	7.50
		425,000	$	6.00		8.8304		112,496	$	6.00

At December 31, 2020, unrecognized compensation expense related to non-vested stock options was approximately $176,000, which is expected to be recognized over a weighted average period of 2.93 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, 2020 there were 23,635 shares available for future issuance under the ESPP Plan. We issued 15,388, and 13,699 common shares under the ESPP Plan in 2020, and 2019, respectively.

Share Purchases - On April 30, 2020, our Board of Directors approved a program authorizing to purchase up to $10 million of our common stock, of which $1.0 million had been utilized as of December 31, 2020. During the year ended December 31, 2020, we repurchased 298,214 shares of our common stock. The shares may be purchased from time to time in the open market or through privately negotiated transactions at management’s discretion, depending upon market conditions and other factors. The authorization to repurchase Company stock expires on December 31, 2021. Repurchases will be made under the program using our own cash resources and will been accordance with Rule 10b-18 under the Securities Exchange Act of 1934 and other applicable laws, rules and regulations. The program does not obligate us to acquire any particular amount of common stock and the program may be modified or suspended at any time at our Board of Director’s discretion.

Dividends – We did not pay dividends in the years ended December 31, 2020 and 2019.

Commitments and Contingent Liabilities

7.	COMMITMENTS AND CONTINGENT LIABILITIES

Lease Commitments – We own our principal office and research facility in Bedford, Massachusetts, which we have occupied since November 1997. We have no real estate lease commitments and no equipment lease commitments.

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.
