Description of business	1. Description of business TransAct Technologies Incorporated (together with its subsidiaries, “TransAct,” the “Company,” “we,” “us,” or “our”), which has its headquarters in Hamden, Connecticut and its primary operating facility in Ithaca, New York, operates in one operating segment: software-driven technology and printing solutions for high growth markets including food service technology, casino and gaming, POS automation, and oil and gas markets. Our solutions are designed from the ground up based on market and customer requirements and are sold under the BOHA!^TM, AccuDate™, Epic®, Ithaca®, EPICENTRAL^TM and Printrex® product brands. We sell our products to original equipment manufacturers, value-added resellers, select distributors, and directly to end-users. Our product distribution spans across the Americas, Europe, the Middle East, Africa, Asia, Australia, New Zealand, the Caribbean Islands and the South Pacific. TransAct also provides world-class service, spare parts, accessories and printing supplies to its growing worldwide installed base of products.

Summary of significant accounting policies

2. Summary of significant accounting policies

Principles of consolidation: The accompanying Consolidated Financial Statements include the accounts of TransAct and its wholly-owned subsidiaries, which require consolidation, after the elimination of intercompany accounts, transactions and unrealized profit.

Use of estimates: The preparation of Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and disclosure of contingent assets and liabilities as of the date of the Consolidated Financial Statements and the reported amounts of sales and expenses during the reporting period. Actual results could differ from those estimates.

Segment reporting: We apply the provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 280, “Segment Reporting.” We view our operations and manage our business as one segment: the design, development and marketing of software-driven technology and printing solutions and providing printer and terminal related software, services, supplies and spare parts. Factors used to identify TransAct’s single operating segment include the organizational structure of the Company and the financial information available for evaluation by the chief operating decision-maker in making decisions about how to allocate resources and assess performance.

Cash and cash equivalents: We consider all highly liquid investments with a maturity date of three months or less at date of purchase to be cash equivalents.

Allowance for doubtful accounts: We establish an allowance for doubtful accounts to ensure trade receivables are valued appropriately. We maintain an allowance for doubtful accounts based on a variety of factors, including the length of time receivables are past due, significant one-time events and historical experience. We record a specific allowance for individual accounts when we become aware of a customer’s inability to meet its financial obligations, such as in the case of bankruptcy filings or deterioration in the customer’s operating results or financial position. If circumstances related to customers change, we further adjust estimates of the recoverability of receivables.

The following table summarizes the activity recorded in the valuation account for accounts receivable:

	Year Ended December 31,
(In thousands)	2020			2019
Balance, beginning of period	$	221		$	205
Additions charged to costs and expenses		1			39
Deductions		(2	)		(23	)
Balance, end of period	$	220		$	221

Inventories: Inventories are stated at the lower of cost (principally standard cost, which approximates actual cost on a first-in, first-out basis) or net realizable value. We review net realizable value based on estimated selling prices in the ordinary course of business less estimated costs of completions, disposal and transportation, historical usage and estimates of future demand. Based on these reviews, inventory write-downs are recorded, as necessary, to reflect estimated obsolescence, excess quantities and net realizable value.

Fixed assets: Fixed assets are stated at cost. Depreciation is recorded using the straight-line method over the estimated useful lives. The estimated useful life of tooling is five years; machinery and equipment is ten years; furniture and office equipment is five years to ten years; and computer software and equipment is three years to seven years. Leasehold improvements are amortized over the shorter of the term of the lease or the useful life of the asset. Costs related to repairs and maintenance are expensed as incurred. The costs of sold or retired assets are removed from the related asset and accumulated depreciation accounts and any gain or loss is recognized. Depreciation expense was $1.0 million and $1.1 million in 2020 and 2019, respectively.

Leases: We account for leases in accordance with ASC 842, “Leases” (“ASC 842”) which we adopted effective January 1, 2019. The adoption required a modified retrospective transition approach, applying the new standard to all leases existing at the date of initial application. An entity was allowed to choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. The Company elected to adopt the standard using the effective date, January 1, 2019, as its date of initial application.

The standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification determines whether lease expense is recognized based on an effective interest method for finance leases or on a straight-line basis over the term of the lease for operating leases. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less are accounted for based on existing guidance for operating leases. If risks and rewards are conveyed without the transfer of control, the lease is treated as financing. If the lessor does not convey risks and rewards or control, the lease is treated as operating.

We have elected certain practical expedients available under ASC 842 upon adoption. We have applied the practical expedient which allows prospective transition to ASC 842 on January 1, 2019. Under this transition practical expedient, we did not reassess lease classification, embedded leases or initial direct costs. We have applied the practical expedient for short-term leases. We have lease agreements that include lease and non-lease components, and we have not elected the practical expedients to combine these components for any of our leases. The adoption of ASC 842 had no effect on our Consolidated Statements of Operations. Upon adoption of ASC 842 on January 1, 2019, we recorded a $3.7 million right-of-use asset and a $3.9 million lease liability. The adoption of the new standard had no impact on retained earnings.

We enter into lease agreements for the use of real estate space and certain other equipment under operating leases and we have no financing leases. We determine if an arrangement contains a lease at inception. Our leases are included in Right of use assets and Lease liabilities in our Condensed Consolidated Balance Sheet.

Right of use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Lease right of use assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. Our right-of-use-asset and lease liability was higher at December 31, 2020 compared to December 31, 2019 due to the extension of one of our leases. On February 28, 2020, we entered into an amendment to extend the lease on our facility in Ithaca, New York, which resulted in recording an additional right-of-use-asset and lease liability of $1.5 million. The lease, which was last amended on January 14, 2016, was scheduled to expire on May 31, 2021. The lease amendment provides for an extension of the lease for four additional years from June 1, 2021 to May 31, 2025. Lease expense is recognized on a straight-line basis over the lease term. As most of our leases do not provide an implicit rate, the Company determines its incremental borrowing rate by using the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term, an amount equal to the lease payments in a similar economic environment. Our lease right of use assets exclude lease incentives. Our leases have remaining lease terms of one year to seven years, some of which include options to extend. The majority of our leases with options to extend provide for extensions of up to five years. The exercise of lease renewal options is at our sole discretion and our lease right of use assets and liabilities reflect only the options we are reasonably certain that we will exercise. Lease expense is recognized on a straight-line basis over the lease term.

Goodwill and Intangible assets: We acquire businesses in purchase transactions that result in the recognition of goodwill and intangible assets. The determination of the value of intangible assets requires management to make estimates and assumptions. In accordance with ASC 350-20 “Goodwill,” acquired goodwill is not amortized but is subject to impairment testing at least annually and when an event occurs or circumstances change that indicate it is more likely than not an impairment exists. We perform a fair value-based impairment test to the carrying value of goodwill and indefinite-lived intangible assets on an annual basis (as of December 31) and, if certain events or circumstances indicate that an impairment loss may have been incurred, on an interim basis. The Company utilizes the option to first assess qualitative factors to determine whether it is necessary to perform the Step 1 quantitative goodwill impairment test in accordance with the applicable accounting standards. Under the qualitative assessment, management considers relevant events and circumstances including but not limited to macroeconomic conditions, industry and market considerations, Company performance and events directly affecting the Company. If the Company determines that the Step 1 quantitative impairment test is required, management estimates the fair value of the reporting unit primarily using the income approach, which reflects management’s cash flow projections, and also evaluates the fair value using the market approach. Factors considered that may trigger an interim period impairment review of either acquired goodwill or intangible assets are: significant underperformance relative to expected historical or projected future operating results; significant changes in the manner of use of acquired assets or the strategy for the overall business; significant negative industry or economic trends; and significant decline in market capitalization relative to net book value. Finite lived intangible assets are amortized and are tested for impairment when appropriate.

During the three months ended March 31, 2020, our stock price declined to the lowest price since 2009. We determined that the significant decline in our market capitalization and broader economic downturn arising from the COVID-19 pandemic was a triggering event and an indicator that it was more likely than not that the carrying value of goodwill exceeded fair value. Therefore, we concluded that quantitative analyses were required to be performed due to the triggering event occurring during the first quarter of 2020. We utilized an implied market value method under the market approach to calculate the fair value of the Company as of March 31, 2020, which we determined was the best approximation of fair value in the current social and economic environment. Based on our interim impairment assessment as of March 31, 2020, we determined that no goodwill or intangible asset impairment occurred and the fair value of goodwill was substantially higher than our carrying value.

As of December 31, 2020, we have determined that no goodwill or intangible asset impairment has occurred and the fair value of goodwill was substantially higher than our carrying value based on our assessment as of December 31, 2020 when our annual review for impairment was performed.

Revenue recognition: We account for revenue in accordance with ASC Topic 606: Revenue from Contracts with Customers. In accordance with ASC 606, a performance obligation is a promise in a contract with a customer to transfer a distinct good or service to the customer. Some of our contracts with customers contain a single performance obligation, while other contracts contain multiple performance obligations (most commonly when contracts include a hardware product, software and extended warranties). A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied.

The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring services to the customer. To the extent the transaction price includes variable consideration, such as price protection, reserves for returns and other allowances, the Company estimates 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 the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur.

For a majority of our revenue, which consists of printers, terminals, consumables, and replacement parts, the Company recognizes revenue as of a point of time. The transaction price is recognized upon shipment of the order when control of the goods is transferred to the customer and at the time the performance obligation is fulfilled. We also sell a software solution in our casino and gaming market, EPICENTRAL™, that enables casino operators to create promotional coupons and marketing messages and to print them in real time at the slot machine. EPICENTRAL^TM is primarily comprised of both a software component, which is licensed to the customer, and a hardware component. EPICENTRAL™ software and hardware are integrated to deliver the system’s full functionality. The transaction prices from EPICENTRAL™ software license and hardware are recognized upon installation and formal acceptance by the customer when control of the license is transferred to the customer. For out-of-warranty repairs, the transaction price is recognized after the repair work is completed and the printer or terminal is returned to the customer, as control of the product is transferred to the customer and our performance obligation is completed.

Performance obligations are satisfied over time if the customer receives the benefits as we perform work, if the customer controls the asset as it is being produced, or if the product being produced for the customer has no alternative use and we have a contractual right to payment. For our separately priced extended warranty, BOHA! cloud-based software applications, technical support for our food service technology terminals and maintenance agreements (including free one-year maintenance received by customers upon completion of EPICENTRAL™ installation) revenue is recognized over time as the customer receives the benefit. The transaction price from the maintenance services is recognized ratably over time, using output methods, as control of the services is transferred to the customer. Our cloud-based BOHA! software allows customers to use hosted software over the contract period on a subscription basis without taking possession of the software and the subscription price is recognized ratably over the contract period. For extended warranties, the transaction price is recognized ratably over the warranty period, using output methods, as control of the services is transferred to the customer.

When there is more than one performance obligation in a customer arrangement, the Company typically uses the “standalone selling price” method to determine the transaction price to allocate to each performance obligation. The Company sells the performance obligations separately and has established standalone selling prices for its products and services. In the case of an overall price discount, the discount is applied to each performance obligation proportionately based on standalone selling price. To determine the standalone selling price for initial EPICENTRAL™ installations, the Company uses the adjusted market assessment approach.

For contracts with terms of less than 12 months, the Company expenses sales commissions as they are incurred, since the expected amortization period of the cost to obtain a contract is less than 12 months.

Disaggregation of revenue

The following table disaggregates our revenue by market type, as we believe it best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Sales and usage-based taxes are excluded from revenues.

Contract balances

Contract assets consist of unbilled receivables. Pursuant to the over-time revenue recognition model, revenue may be recognized prior to the customer being invoiced. An unbilled receivable is recorded to reflect revenue that is recognized when such revenue exceeds the amount invoiced to the customer. Unbilled receivables are separated into current and non-current assets and included within “Accounts Receivable” and “Other Non-Current Assets” on the Consolidated Balance Sheets as of December 31, 2020. We first recorded contract assets during 2020 upon the start of a long-term BOHA! contract.

Contract liabilities consist of customer prepayments and deferred revenue. Customer prepayments are reported as “Accrued Liabilities” in current liabilities in the Condensed Consolidated Balance Sheets and represent customer payments made in advance of performance obligations in instances where credit has not been extended and is recognized as revenue when the performance obligation is complete. Deferred revenue is reported separately in current liabilities and non-current liabilities and consists of our extended warranty contracts, technical support for our food service technology terminals, EPICENTRAL™ maintenance contracts and prepaid software subscriptions for our BOHA! software applications, and is recognized as revenue as (or when) we perform under the contract. The decrease in current deferred revenue in 2020 compared to 2019 is primarily due to delayed renewals of our EPICENTRAL™ maintenance contracts from COVID-19 related closures of casinos during 2020. Non-current deferred revenue decreased primarily due to decreased sales of long-term extended warranties for a legacy POS printer. During the year ended December 31, 2020, we recognized revenue of $1.3 million related to our contract liabilities as of December 31, 2019.

Net contract assets (liabilities) consist of the following:

	December 31,

Net contract assets (liabilities)	$	50		$	(1,151	)

Remaining performance obligations

Remaining performance obligations represent the transaction price of firm orders for which a good or service has not been delivered to our customer. As of December 31, 2020, the aggregate amount of the transaction price allocated to remaining performance obligations was $4.4 million. The Company expects to recognize revenue on $3.8 million of our remaining performance obligations within the next 12 months, $0.4 million within the next 24 months and the balance of these remaining performance obligations recognized within the next 36 months.

Concentration of credit risk: Financial instruments that potentially expose us to concentrations of credit risk are limited to cash and cash equivalents held by our banks in excess of insured limits and accounts receivable.

Accounts receivable from customers representing 10% or more of total accounts receivable were as follows:

	December 31,
	2020			2019
International Gaming Technology (“IGT”)		11	%		15	%
Scientific Games		–			10	%

Sales to customers representing 10% or more of total net sales were as follows:

	December 31,
	2020			2019
IGT		15	%		14	%

Warranty: We generally warrant our products for up to 24 months and record the estimated cost of such product warranties at the time the sale is recorded. Estimated warranty costs are based upon actual past experience of product repairs and the related estimated cost of labor and material to make the necessary repairs.

The following table summarizes the activity recorded in the accrued product warranty liability:

	December 31,
(In thousands)	2020			2019
Balance, beginning of period	$	215		$	273
Warranties issued		56			181
Warranty settlements		(131	)		(239	)
Balance, end of period	$	140		$	215

$112 thousand and $174 thousand of the accrued product warranty liability were classified as current in Accrued liabilities at December 31, 2020 and 2019, respectively. The remaining $28 thousand and $41 thousand of the accrued product warranty liability as of December 31, 2020 and 2019, respectively, is classified as long-term in Other liabilities.

Engineering, design and product development: Engineering, design and product development expenses include expenses incurred in connection with specialized engineering and design to introduce new products and to customize existing products, and are expensed as a component of operating expenses as incurred. We recorded $5.7 million and $4.4 million of research and development expenses in 2020 and 2019, respectively.

Costs incurred in the engineering, design and product development of a computer software product are charged to expense until technological feasibility has been established, at which point all material software costs are capitalized within Intangible assets in our Consolidated Balance Sheet until the product is available for general release to customers. While judgment is required in determining when technological feasibility of a product is established, we have determined that it is reached after all high-risk development issues have been documented in a formal detailed plan design. The amortization of these costs have been included in cost of sales over the estimated life of the product. During 2019, we contracted several third-parties to develop software for our food service technology products, the cost for which we capitalized. Unamortized development costs for such software were $551 thousand as of December 31, 2020. The total amount charged to cost of sales for capitalized software development costs was $153 thousand and $186 thousand in 2020 and 2019, respectively.

Advertising: Advertising costs are expensed as incurred. Advertising expenses, which are included in selling and marketing expense on the accompanying Consolidated Statements of Operations, for 2020 and 2019 totaled $0.7 million and $1.4 million, respectively. These expenses include items such as consulting and professional services, tradeshows, and print advertising.

Income taxes: The income tax amounts reflected in the accompanying Consolidated Financial Statements are accounted for under the liability method in accordance with ASC 740, “Income Taxes” (“ASC 740”). Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. We assess the likelihood that net deferred tax assets will be realized from future taxable income, and to the extent that we believe that realization is not likely, we establish a valuation allowance. In accordance with ASC 740, we identified, evaluated and measured the amount of benefits to be recognized for our tax return positions.

Foreign currency translation: The financial position and results of operations of our foreign subsidiary in the UK are measured using local currency as the functional currency. Assets and liabilities of such subsidiary have been translated into U.S. dollars at the year-end exchange rate, related sales and expenses have been translated at the exchange rate as of the date the transaction was recognized, and shareholders’ equity has been translated at historical exchange rates. The resulting translation gains or losses, net of tax, are recorded in shareholders’ equity as a cumulative translation adjustment, which is a component of accumulated other comprehensive income. Foreign currency transaction gains and losses, including those related to intercompany balances, are recognized in Other, net on the Consolidated Statements of Operations.

Share-based payments: At December 31, 2020, we have share-based employee compensation plans, which are described more fully in Note 10 - Stock incentive plans. We account for those plans under the recognition and measurement principles of ASC 718, “Compensation – Stock Compensation”. Share-based compensation expense is measured at the grant date, based on the estimated fair value of the award, and is recognized as expense over the employee’s requisite service period.

We use the Black-Scholes option-pricing model to calculate the fair value of share-based awards. The key assumptions for this valuation method include the expected term of the option, stock price volatility, risk-free interest rate, dividend yield, market price of our underlying stock and exercise price. Many of these assumptions are require judgment and are highly sensitive in the determination of compensation expense. Forfeitures are recognized as they occur.

Net income and loss per share: We report net income or loss per share in accordance with ASC 260, “Earnings per Share (EPS).” Under this guidance, basic EPS, which excludes dilution, is computed by dividing income or loss available to common shareholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. Diluted EPS includes in-the-money stock options using the treasury stock method. During a loss period, the assumed exercise of in-the-money stock options has an anti-dilutive effect, and therefore, these instruments are excluded from the computation of diluted EPS. See Note 12 - Earnings per share.

Note receivable [Abstract]
Note receivable	3. Note receivable The note receivable balance relates to loans given to a third party software developer for whom we license our food service technology software with an interest rate of 4.5%, which were due in April 2020. We intend to collect the remaining principal and interest due under the note pursuant to a lender recourse provision that enables us to apply payments that would have been due to the third party under revenue sharing provisions of a previously signed license agreement towards the loan balance. A $100 thousand royalty fee was scheduled to be paid to the third party in January 2021 that was instead applied towards the note receivable balance as it became due. As a result $100 thousand of the balance was classified as current and the remaining $1.6 million is expected to be reduced thereafter using the lender recourse provision. Notes receivable are stated at unpaid balances and interest income is recognized on the accrual method. As of December 31, 2020, we have no allowances for loan losses, unamortized deferred loan fees or unearned discounts.

Borrowings [Abstract]
Borrowings	9. Borrowings On March 13, 2020, we entered into a new credit facility (the “Siena Credit Facility”) with Siena Lending Group LLC. The Siena Credit Facility provides for a revolving credit line of up to $10.0 million expiring on March 13, 2023. Borrowings under the Siena Credit Facility bear a floating rate of interest equal to the greatest of (i) the prime rate plus 1.75%, (ii) the federal funds rate plus 2.25%, and (iii) 6.50%. The total deferred financing costs related to expenses incurred to complete the Siena Credit Facility was $245 thousand, which were reported as “other current assets” in current assets and “other assets” in non-current assets in the Condensed Consolidated Balance Sheets. We also pay a fee of 0.50% on unused borrowings under the facility. Borrowings under the facility are secured by a lien on substantially all the assets of the Company. The Siena Credit Facility imposes a minimum EBITDA financial covenant on the Company and borrowings are subject to a borrowing base based on (i) 85% of eligible accounts receivable plus the lesser of (a) $5.0 million and (b) 50% of eligible raw material and 60% of finished goods inventory. As of December 31, 2020, we had $4.5 million of borrowing capacity available under the Siena Credit Facility and had no outstanding borrowings. We were in compliance with all financial covenants of the Siena Credit Facility at December 31, 2020. Prior to entering the Siena Credit Facility, we maintained a credit facility with TD Bank N.A. (“TD Bank) which provided for a $20 million revolving credit line. Borrowings under the revolving credit line bore a floating rate of interest at the prime rate minus one percent and were secured by a lien on all our assets. We also paid a fee of 0.125% on unused borrowings under the revolving credit line. On May 1, 2020 (the “Loan Date”), the Company was granted the PPP Loan from Berkshire Bank in the aggregate amount of $2.2 million, pursuant to the PPP. The PPP Loan, which is evidenced by a Note dated the Loan Date issued by the Company (the “Note”) in favor of Berkshire Bank, as lender (the “PPP Lender”), matures on May 1, 2022 and bears interest at a fixed rate of 1.0% per annum, accruing from the Loan Date and payable monthly. No payments were due on the PPP Loan for six months from the date of first disbursement, and if a loan forgiveness application is submitted to the SBA within 10 months after the end of the covered period, no payments are due until the date on which the SBA remits the loan forgiveness amount to the PPP Lender (or notifies the PPP Lender that no loan forgiveness is allowed), but interest continues to accrue during the deferment period. If no loan forgiveness is allowed, the Company will be required to pay the PPP Lender equal monthly payments of principal and interest based on the principal amount outstanding on the PPP Loan, plus interest outstanding at the end of the deferment period, and taking into account any reductions in the principal amount due to forgiveness, if any. The Note is unsecured and guaranteed by the SBA. The Note may be prepaid by the Company at any time prior to maturity with no prepayment penalties. The Note provides for customary defaults, including failure to make payment when due or to fulfill the Company’s obligations under the Note or related documents, reorganizations, mergers, consolidations or other changes to the Company’s business structure, and certain defaults on other indebtedness, bankruptcy events, adverse changes in financial condition or civil or criminal actions. The PPP Loan may be accelerated upon the occurrence of a default. Under the terms of the PPP, the PPP Loan may be forgiven to the extent that funds from the PPP Loan are used for payroll costs and costs to continue group health care benefits, as well as for interest on mortgage obligations incurred before February 15, 2020, rent under lease agreements in effect before February 15, 2020, utilities for which service began before February 15, 2020, and interest on debt obligations incurred before February 15, 2020 (collectively, “qualifying expenses”), subject to conditions and limitations provided in the CARES Act. At least 60% (as amended) of the proceeds from the PPP Loan must be used for eligible payroll costs for the PPP Loan to be forgiven. The Company has maximized the use of PPP Loan proceeds for qualifying expenses and intends to apply for forgiveness of the PPP Loan in accordance with the terms of the CARES Act, as amended by the Paycheck Protection Flexibility Act of 2020. Whether forgiveness will be granted and in what amount is subject to an application to, and approval by, the SBA and may also be subject to further requirements in any regulations and guidelines the SBA may adopt. The PPP Loan is classified as “Long-term debt” in the Condensed Consolidated Balance Sheet until the forgiveness determination has been made by the SBA. In the event that no portion of the PPP Loan is forgiven by the SBA, $1.5 million in principal and interest of the $2.2 million PPP Loan would be due in 2021 with the remaining balance due in 2022.

Stock incentive plans

10. Stock incentive plans

Stock incentive plans. We currently have two primary stock incentive plans: the 2005 Equity Incentive Plan and the 2014 Equity Incentive Plan, which provide for awards to executives, key employees, directors and consultants. The plans generally provide for awards in the form of: (i) incentive stock options, (ii) non-qualified stock options, (iii) restricted stock, (iv) restricted stock units (which may include performance-based vesting), (v) stock appreciation rights or (vi) limited stock appreciation rights. Awards granted under these plans have exercise prices equal to 100% of the fair market value of the common stock at the date of grant. Awards granted have a ten-year term and generally vest over a two-year to five-year period, unless automatically accelerated for certain defined events. As of May 2014, no new awards may be made under the 2005 Equity Incentive Plan. Under our 2014 Equity Incentive Plan, as amended in May 2020, we are authorized to grant awards of up to 2,200,000 shares of TransAct common stock. At December 31, 2020, 837,204 shares of common stock remained available for issuance under the 2014 Equity Incentive Plan.

Under the assumptions indicated below, the weighted-average per share fair value of stock option grants for 2020 and 2019 was $3.19 and $3.01, respectively. We also issued restricted stock units for certain executives and directors that vest over a specified period of time, and in some instances require achieving certain performance metrics. The weighted-average per share fair value of these restricted stock units was $9.77 and $10.46 in 2020 and 2019, respectively.

The table below indicates the key assumptions used in the option valuation calculations for options granted in 2020 and 2019 and a discussion of our methodology for developing each of the assumptions used in the valuation model:

	December 31,
	2020			2019
Expected option term (in years)		7.0			6.8
Expected volatility		41.7	%		38.8	%
Risk-free interest rate		0.9	%		2.6	%
Dividend yield		0.0	%		3.5	%

Expected Option Term - This is the weighted average period of time over which the options granted are expected to remain outstanding giving consideration to our historical exercise patterns. Options granted have a maximum term of ten years and an increase in the expected term will increase compensation expense.

Expected Volatility – The stock volatility for each grant is measured using the weighted average of historical daily price changes of our common stock over the most recent period approximately equal to the expected option term of the grant. An increase in the expected volatility factor will increase compensation expense.

Risk-Free Interest Rate - This is the U.S. Treasury rate in effect at the time of grant having a term approximately equal to the expected term of the option. An increase in the risk-free interest rate will increase compensation expense.

Dividend Yield –The dividend yield is calculated by dividing the annual dividend declared per common share by the weighted average market value of our common stock on the date of grant. An increase in the dividend yield will decrease compensation expense.

For 2020 and 2019, we recorded $876 thousand and $692 thousand of share-based compensation expense, respectively, included primarily in general and administrative expense in our Consolidated Statements of Operations. We also recorded income tax benefits of $193 thousand and $152 thousand in 2020 and 2019, respectively, related to such share-based compensation. At December 31, 2020, these benefits are recorded as a deferred tax asset in the Consolidated Balance Sheets.

Equity award activity in the 2005 Equity Incentive Plan and the 2014 Equity Incentive Plan is summarized below:

	Stock Options					Restricted Stock Units
	Number of Shares			Average Price*		Number of Units			Average Price**
Outstanding at December 31, 2019		1,142,468		$	9.23		90,575		$	10.46

*	weighted average exercise price per share

**	weighted-average contractual remaining term in years

Shares that are issued upon exercise of employee stock awards are newly issued shares and not issued from treasury stock. As of December 31, 2020, unrecognized compensation cost related to non-vested equity awards granted under our stock incentive plans is approximately $1.9 million, which is expected to be recognized over a weighted average period of 2.2 years.

The total fair value of awards vested during the years ended December 31, 2020 and 2019 was $1.7 million and $1.6 million, respectively. The total intrinsic value (which is the amount by which the stock price exceeded the exercise price on the date of exercise) of stock options exercised during the years ended December 31, 2020 was $174 thousand and cash received from option exercises was $375 thousand in 2020. No stock options were exercised during the year ended December 31, 2019. We recorded a realized tax provision in 2020 from equity-based awards of $14 thousand related to options exercised.

11. Income taxes

The components of the income tax benefit are as follows:

	December 31,
(In thousands)	2020			2019
Current:
Federal	$	(2,141	)	$	58
State		17			51
Foreign		(48	)		(58	)

State		(36	)		5
Foreign		152			-
		(367	)		(294	)
Income tax benefit	$	(2,539	)	$	(149	)

Our effective tax rates were 31.1 % and (40.6)% for 2020 and 2019, respectively. The effective tax rate for 2020 included the impact of the net operating loss (“NOL”) that we expect to carry back to prior years. The CARES Act permits NOLs incurred in 2018, 2019 and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. We generated a NOL for 2020 which we will carry back to tax years that had a federal statutory tax rate of 34% compared to 21% in 2020. We recorded an unusually high tax benefit in 2019 due to the impact of R&D credits on a near break-even level of income before income tax.

At December 31, 2020, we have no federal net operating loss carryforwards and $33 thousand of state net operating loss carryforwards, $460 thousand in R&D credit carryforwards, and no state tax credit carryforwards. Foreign loss before taxes was $468 thousand and $515 thousand in 2020 and 2019, respectively.

Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the Consolidated Financial Statements. Our deferred tax assets and liabilities were comprised of the following:

	December 31,
(In thousands)	2020			2019
Deferred tax assets:
Foreign net operating losses	$	563		$	538
Depreciation		302			165
Inventory reserves		719			916
Deferred revenue		47			58
Warranty reserve		31			47
Stock compensation expense		731			701
Other accrued compensation		388			226
R&D credit carryforward		460			111
Other liabilities and reserves		394			276
Gross deferred tax assets		3,635			3,038
Valuation allowance		(659	)		(444	)
Net deferred tax assets		2,976			2,594

Deferred tax liabilities:
Other		37			29
Net deferred tax liabilities		37			29
Total net deferred tax assets	$	2,939		$	2,565

As of December 31, 2020 a valuation allowance of $659 thousand has been established for foreign net operating loss carryforwards that are not expected to be used. The following table summarizes the activity recorded in the valuation allowance on the deferred tax assets:

	Year Ended December 31,
(In thousands)	2020		2019
Balance, beginning of period	$	444	$	390
Additions charged to income tax provision		215		54
Balance, end of period	$	659	$	444

Differences between the U.S. statutory federal income tax rate and our effective income tax rate are analyzed below:

	Year Ended December 31,
	2020			2019

Federal statutory tax rate		21.0	%		21.0	%
U.S. corporate tax rate change		9.5			–
R&D credit		4.2			(83.2	)
State income taxes, net of federal income taxes		0.2			12.0
Business meals and entertainment		0.1			5.4
Miscellaneous permanent items		–			1.4
Uncertain tax positions		(0.2	)		1.0
Foreign-derived intangible income deduction		–			(5.4	)
Stock award excess tax benefit		(0.3	)		(8.4	)
Stock option cancellations		(0.5	)		0.8
Valuation allowance and tax accruals		(2.6	)		14.8
Other		(0.3	)		–
Effective tax rate		31.1	%		(40.6	)%

We had $121 thousand and $107 thousand of total gross unrecognized tax benefits at December 31, 2020 and 2019, respectively that, if recognized, would favorably affect the effective income tax rate in any future periods. We are not aware of any events that could occur within the next twelve months that could cause a significant change in the total amount of unrecognized tax benefits. A tabular reconciliation of the gross amounts of unrecognized tax benefits at the beginning and end of the year is as follows:

	December 31,
(In thousands)	2020			2019
Unrecognized tax benefits as of January 1	$	107		$	104
Tax positions taken during the current period		41			28
Lapse of statute of limitations		(27	)		(25	)
Unrecognized tax benefits as of December 31	$	121		$	107

We expect $24 thousand of the $121 thousand of unrecognized tax benefits will reverse in 2021 upon the expiration of the statute of limitations.

We recognize interest and penalties related to uncertain tax positions in the income tax provision. We have accrued interest and penalties related to uncertain tax positions of $19 thousand and $18 thousand as of December 31, 2020 and 2019, respectively.

We are subject to U.S. federal income tax as well as income tax of certain state and foreign jurisdictions. We have substantially concluded all U.S. federal income tax, state and local, and foreign tax matters through 2016. However, our federal tax returns for the years 2017 through 2019 remain open to examination. Various state and foreign tax jurisdiction tax years remain open to examination as well, though we believe that any additional assessment would be immaterial to the Consolidated Financial Statements.

Earnings per share

12. Earnings per share

Earnings per share was computed as follows (in thousands, except per share amounts):

	Year Ended December 31,
	2020			2019
Net (loss) income	$	(5,630	)	$	516

Shares:
Basic: Weighted average common shares outstanding		7,827			7,466
Add: Dilutive effect of outstanding equity awards as determined by the treasury stock method		-			211
Diluted: Weighted average common and common equivalent shares outstanding		7,827			7,677

Net (loss) income per common share:
Basic	$	(0.72	)	$	0.07
Diluted		(0.72	)		0.07

The computation of diluted earnings per share excludes the effect of the potential exercise of stock awards, including stock options, restricted stock units and performance stock awards, when the average market price of the common stock is lower than the exercise price of the related stock award during the period. These outstanding stock awards are not included in the computation of diluted earnings per share because the effect would be anti-dilutive. Anti-dilutive stock awards excluded from the computation of earnings per dilutive share were 1,284,000 and 447,000 , at December 31, 2020 and 2019, respectively.
