NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in thousands except share and per share data and as otherwise noted)

1. Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all the information and footnotes required by U.S. GAAP for complete financial statements.  In the opinion of management, all adjustments of a normal, recurring nature that are considered necessary for a fair presentation have been included.  For further information, refer to the audited consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Form 10-K”).

Throughout this Quarterly Report on Form 10-Q, including under Part 1, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” we disclose certain measures that the Company has taken in response to the macroeconomic impacts of the novel coronavirus (“COVID-19”).  The full extent to which the COVID-19 pandemic will directly or indirectly impact the Company’s business, results of operations and financial condition will depend on future developments that remain highly uncertain at this time.

Nature of Operations

PCTEL, Inc. (the “Company”) was incorporated in California in 1994 and reincorporated in Delaware in 1998. The Company is a

leading global provider of wireless technology, including purpose-built Industrial Internet of Things (“IoT”) devices, antenna systems,

and test and measurement solutions. The Company solves complex wireless challenges to help organizations stay connected, transform, and grow, and the Company has expertise in radio frequency (“RF”), digital and mechanical engineering. The Company has two businesses (antennas & Industrial IoT devices and test & measurement products) that address three market segments: Enterprise Wireless, Intelligent Transportation, and Industrial IoT.

The Company’s principal executive offices are located at 471 Brighton Drive, Bloomingdale, Illinois 60108. The telephone number at

that address is (630) 372-6800 and the website is www.pctel.com. Additional information about the Company can be obtained on the Company’s website; however, the information within, or that can be accessed through, the Company’s website, is not part of this Quarterly Report on Form 10-Q. 

Basis of Consolidation

The unaudited interim condensed consolidated financial statements of the Company include the condensed consolidated balance sheets for the period ended June 30, 2021 and December 31, 2020, the condensed consolidated statement of cash flows for the six months ended June 30, 2021 and 2020, and the condensed consolidated statements of operations, condensed consolidated statements of comprehensive (loss) income, and the condensed consolidated statements of stockholders’ equity for the three and six months ended June 30, 2021 and 2020, respectively. The interim condensed consolidated financial statements are unaudited and reflect all adjustments of a normal recurring nature that are, in the opinion of management, necessary for a fair presentation of the interim period financial statements.  The condensed consolidated balance sheet as of December 31, 2020 is derived from the audited financial statements as of December 31, 2020.  

The unaudited interim condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”).  Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted.  The significant accounting policies followed by the Company are set forth in the 2020 Form 10-K.  There were no material changes in the Company’s significant accounting policies during the three and six months ended June 30, 2021.  In addition, the Company reaffirms the use of estimates in the preparation of the financial statements as set forth in the 2020 Form 10-K.  These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the 2020 Form 10-K.  The results of operations for the period ended June 30, 2021 may not be indicative of the results for the period ending December 31, 2021.

Foreign Operations

Cross-border transactions, both with external parties and in our internal operations, result in exposure to foreign exchange rate fluctuations. We are exposed to currency risk with the Chinese Yuan due to our operations in China, and with other foreign currencies related to the acquisition of Smarteq (see Note 4) and related to suppliers and employees outside the U.S. Fluctuations could have an adverse effect on our results of operations and cash flows. We manage certain operating activities at the local level with revenues,

9

costs, assets, and liabilities generally being denominated in local currencies. However, our results of operations and assets and liabilities are reported in U.S. dollars and thus will fluctuate with changes in exchange rates between such local currencies and the U.S. dollar.  Gains and losses resulting from transactions originally in foreign currencies and then translated into U.S. dollars are included in the condensed consolidated statements of operations.  For the six months ended June 30, 2021, approximately 6% of revenues and 18% of expenses were transacted in foreign currencies as compared to 3% and 18% for the six months ended June 30, 2020.  Net foreign exchange losses resulting from foreign currency transactions included in other income, net were $(53) and $(18) for the three months ended June 30, 2021 and 2020, respectively.  Net foreign exchange gains(losses) resulting from foreign currency transactions included in other income, net was $(45) and $19 for the six months ended June 30, 2021 and 2020, respectively.          

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”), Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (ASU 2017-14).  This guidance eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge.  Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value.  The changes are effective for smaller reporting companies for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, and early adoption is permitted.  The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (“Topic 848”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This update provides optional expedients and exceptions for applying generally accepted accounting principles to certain contract modifications and hedging relationships that reference London Inter-bank Offered Rate (LIBOR) or another reference rate expected to be discontinued. Topic 848 is effective upon issuance and generally can be applied through December 31, 2022.  The Company is currently evaluating the impact of Topic 848 on the consolidated financial statements.

2. Fair Value of Financial Instruments

The Company follows accounting guidance for fair value measurements and disclosures, which establishes a fair value hierarchy that requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.  Fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three-tier fair value hierarchy has been established, which prioritizes the inputs used in measuring fair value as follows:

Level 1: inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2: inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities.

Level 3: unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Cash equivalents are measured at fair value and investments are recognized at amortized cost in the Company’s financial statements.  Accounts receivable is a financial asset with a carrying value that approximates fair value due to the short-term nature of these assets.  Accounts payable, accrued employee compensation and certain operating liabilities are financial liabilities with a carrying value that approximates fair value due to the short-term nature of these liabilities.

4. Business Combinations

On April 30, 2021, the Company acquired all the outstanding stock of Smarteq Wireless Aktiebolag (“Smarteq”), a Swedish company based in Kista, Sweden that designs antennas for specialized industrial IoT and vehicular applications, pursuant to a Share Sale and Purchase Agreement (the “SPA”) between PCTEL and Allgon Aktiebolag, a Swedish company and holder of the outstanding stock of Smarteq. Smarteq owns all the outstanding stock of SAS Smarteq France (“Smarteq France”), which engages in sales of Smarteq products.

Pursuant to the SPA, the Company acquired Smarteq for a cash purchase price consisting of SEK 53.0 million plus working capital adjustments of SEK 1.6 million and an adjustment for the net cash at closing of SEK 2.1 million for total cash consideration of SEK 56.8 million ($6.8 million), all of which was provided from PCTEL’s existing cash. The Company believes the acquisition of Smarteq will provide a strong local presence, expertise, and channel partners to accelerate revenue growth in Europe, as well as a complementary portfolio of products for our Industrial IoT and intelligent transportation customers worldwide.  The results for Smarteq are combined with the Company’s antenna and Industrial IoT device product line.  The Company applied the provisions of Accounting Standards Codification (ASC) 805, Business Combinations, in accounting for its acquisitions. It requires the Company to recognize separately from goodwill the assets acquired, and the liabilities assumed, at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the acquisition date fair values of the net assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions where applicable to accurately value assets acquired and liabilities assumed at the acquisition date its estimates are inherently uncertain and subject to refinement. The purchase price allocation is preliminary because the evaluations necessary to assess the fair values of the net assets acquired are still in process.  As a result, during the measurement period, which may be up to one year from the acquisition date, the Company will record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments will be recorded to the consolidated statements of operations.  The operating results of the acquired business are included in the Company’s Consolidated Financial Statements from the date of the acquisition.

Fair Value of Purchase Consideration:

The following table summarizes the fair value of purchase consideration to acquire Smarteq:

Fair value of purchase consideration
Cash	$	6,785
Working capital adjustment		(5	)
Total purchase consideration	$	6,780

11

Assumptions in the Allocations of Purchase Price

The Company prepared the purchase price allocation and in doing so utilized reports of a third-party valuation expert to calculate the fair value of the identifiable intangible assets.  Estimates of fair value require management to make significant estimates and assumptions which are preliminary and subject to change upon finalization of the valuation analysis. The goodwill recognized is attributable primarily to the acquired workforce, expected synergies, and other benefits that the Company believes will result from integrating the Smarteq operations with the operations of the Company. Updates to and/or completion of the valuations of certain assets acquired and liabilities assumed may result in changes to the recorded amounts of assets and liabilities, with corresponding adjustments to goodwill amounts in subsequent periods. The Company expects to complete the purchase price allocation within 12 months of the respective acquisition date.  The areas that are not yet finalized relate to intangible assets, goodwill and inventory.

The fair value of the customer relationships was determined using the multi-period excess earnings method (“MPEEM”). MPEEM estimates the value of an intangible asset by quantifying the amount of residual (or excess) cash flows generated by the future

12

customer cash flows, and discounting those cash flows to the present value. Future cash flows for customers were estimated based on forecasted revenue and costs, taking into account the growth rates, customer attrition, and contributory charges. The fair value of the customer backlog was calculated using the present value of the cash flows associated with the acquired backlog.

The fair values of the trade names, developed technology, and exclusive rights were determined using the relief-from-royalty method. The relief-from-royalty method is a specific application of the discounted-cash-flow method, which is a form of the income approach. It is based on the principle that ownership of the intangible asset relieves the owner of the need to pay a royalty to another party in exchange for rights to use the asset. Key assumptions to estimate the hypothetical royalty rate include observable royalty rates, which are royalty rates in negotiated licenses and market-based royalty rates which are royalty rates found in available market data for licenses involving similar assets.

The fair value of covenants to non-compete was estimated using the with-or-without method. The with-and-without method estimates the value of an intangible asset by quantifying the loss of economic profits under a hypothetical condition where only the subject intangible does not exist and needs to be re-created. Projected revenues, operating expenses and cash flows are calculated in each "with" and "without" scenario and the difference in the cash flow is discounted to present value.

Inventory was valued at net realizable value.  Raw materials were valued at book value and finished goods were valued assuming hypothetical revenues from finished goods adjusted for disposal costs, profit attributable to the seller and holding costs. An inventory step-up of $0.5 million is included in the purchase price allocation above.  Approximately $0.3 million of the inventory step-up was recognized during the three months ended June 30, 2021.  

The Company assumed gross accounts receivable of $1.4 million.  Based on Smarteq’s bad debt experience and a review of the receivables, the Company does not anticipate an issue with collectability.  

The Company assumed liabilities in the acquisition which primarily consist of accounts payable, accrued employee compensation and certain operating liabilities. The fair value of the liabilities assumed are valued at their cash settlement value.

As part of the acquisition of Smarteq on April 30, 2021, the Company assumed an office lease. The office in Kista, Sweden has 4,080 square feet used for engineering, sales, and administration and the lease term is through July 31, 2023.  On the acquisition date, the Company recorded $0.2 million for each of the right-of-use assets and the lease liabilities.

The Company assumed Smarteq France’s five-year loan of approximately $0.1 million with an interest rate of 0.57%.  The loan was part of a program from the French Ministry of Economy and Finance to support for French businesses during the COVID-19 pandemic.  The loan is denominated in Euros.  Payment of the interest and principal on the loan are deferred until June 2022 and the loan term ends in May 2026.  

The Company recorded net deferred tax assets of $2.4 million, primarily relating to deferred tax assets for net operating losses. The Company also booked a deferred tax asset for inventory reserves and deferred tax liabilities related to intangible asset amortization that is not deductible for income taxes.  The Company booked a full valuation allowance against the net deferred tax assets.  While the Company expects book and tax profits in 2021 and future periods, Smarteq has recorded a three-year cumulative tax loss.  Based on this objective evidence and uncertainty associated with the COVID-19 pandemic, the Company recorded a full valuation allowance on the opening balance sheet.

Goodwill recorded in connection with the acquisition was $3.3 million. The Company does not expect to deduct any of the acquired goodwill for tax purposes. The Company recorded $0.3 million of transaction costs in general and administrative expenses in the statement of operations.  The transaction costs will not be deductible for income tax purposes.

Cash and Cash Equivalents

At June 30, 2021 and December 31, 2020, cash and cash equivalents included bank balances and investments with original maturities of less than 90 days.  At June 30, 2021 and December 31, 2020, the Company’s cash equivalents were invested in highly liquid AAA rated money market funds that are required to comply with Rule 2a-7 of the Investment Company Act of 1940.  Such funds utilize the amortized cost method of accounting, seek to maintain a constant $1.00 per share price, and are redeemable upon demand.  The Company restricts its investments in AAA money market funds to those invested 100% in either short-term U.S. government agency securities or bank repurchase agreements collateralized by these same securities.  The fair values of these money market funds are established through quoted prices in active markets for identical assets (Level 1 inputs).  The Company’s cash in U.S. banks is insured by the Federal Deposit Insurance Corporation up to the insurable limit of $250.

The Company had cash in foreign bank accounts of $3.2 million at June 30, 2021 and $2.9 million at December 31, 2020.  The Company had $2.3 million and $2.9 million of cash and cash equivalents in bank accounts in China at June 30, 2021 and December 31, 2020, respectively, and the Company had $0.9 million of cash in its Sweden and France bank accounts at June 30, 2021.

As of June 30, 2021, the Company has no intention of repatriating the cash in its foreign bank accounts.  If the Company decides to repatriate the cash in the foreign bank accounts, it may have trouble doing so in a timely manner.  The Company may also be exposed to foreign currency fluctuations and taxes if it repatriates these funds.   

Investments

At June 30, 2021 and December 31, 2020, the Company’s investments consisted of corporate bonds with ratings at the purchase date of A or higher and certificates of deposit.

6. Goodwill and Intangible Assets

Goodwill    

The change in the carrying amount of goodwill during the six months ended June 30, 2021 is as follows:

	Amount
Balance at December 31, 2020	$	3,332
Acquisition of Smarteq		3,259
Foreign currency translation		(69	)
Balance at June 30, 2021	$	6,522

The Company performs an annual impairment test of goodwill as of the end of the first month of the fourth fiscal quarter (October 31), or at an interim date if an event occurs or if circumstances change that would indicate that an impairment loss may have been incurred. In performing the annual impairment test, the Company may consider qualitative factors that would indicate possible impairment. A quantitative fair value assessment is also performed at the reporting unit level. If the fair value exceeds the carrying value, then goodwill is not impaired, and no further testing is performed. If the carrying value exceeds the fair value, the implied fair value of goodwill is then compared against the carrying value of goodwill to determine the amount of impairment.  In addition to the annual impairment test, the Company is required to regularly assess whether a triggering event has occurred which would require interim impairment testing. The Company considered the current and expected future economic and market conditions surrounding the COVID-19 pandemic and its impact on each of the reporting units. Further, the Company assessed the current market capitalization, and financial forecasts.  There were no triggering events during the six months ended June 30, 2021 and June 30, 2020.  The Company will continue to monitor goodwill for impairment going forward.

7. Balance Sheet Information

Accounts Receivable

17

Accounts receivable are recorded at invoiced amounts with standard net terms that range between 30 and 90 days.  The Company extends credit to its customers based on an evaluation of a customer’s financial condition and collateral is generally not required.  The Company records reserves for credit losses and credit allowances that reduce the value of accounts receivable to fair value.

The allowances for accounts receivable consisted of the following:

	June 30, 2021		December 31, 2020
Credit loss provision	$	32	$	66
Credit allowances		48		47
Total allowances	$	80	$	113

Effective January 1, 2020, the Company adopted ASU 2016-13.  This ASU replaces the incurred loss impairment model with an expected loss impairment model for financial instruments, including accounts receivable.  The amendment requires entities to consider forward-looking information to estimate expected credit losses.  The Company did not record an adjustment upon adoption of ASU 2016-13.  

The Company is exposed to credit losses primarily through the sale of products. The Company’s expected loss methodology for accounts receivable is developed using historical collection experience, current and future economic market conditions, and a review of the current status of customers’ trade accounts receivable. Due to the short-term nature of accounts receivable, the estimate of amount of accounts receivable that may not be collected is based on aging of the account receivable balances and the financial condition of customers. Additionally, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. The Company’s monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of customers' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible. The Company’s allowance for credit losses was $0.03 million at June 30, 2021 and $0.07 million at December 31, 2020.  

The following table summarizes the allowance for credit losses activity during the six months ended June 30, 2021:

Restricted Stock Units

The Company grants service-based restricted stock units as employee incentives.  Restricted stock units are primarily granted to foreign employees for long-term incentive purposes.  Employee restricted stock units are service-based awards and are amortized over the vesting period.  At the vesting date, these units are converted to shares of common stock.  The Company records expense on a straight-line basis for restricted stock units.

The following table summarizes the restricted stock unit activity during the six months ended June 30, 2021:

	Shares			Weighted Average Fair Value
Unvested Restricted Stock Units - December 31, 2020		9,083		$	7.02

The following table summarizes information about stock options outstanding under all stock option plans:

	Options Outstanding					Options Exercisable
Range of Exercise Prices	Number Outstanding		Weighted Average Contractual Life (Years)	Weighted- Average Exercise Price		Number Exercisable		Weighted Average Exercise Price
$ 5.06 - $ 6.98		4,000	2.92	$	6.02		3,664	$	5.93

The weighted average contractual life and intrinsic value of options outstanding and options exercisable at June 30, 2021, was the following:

	Weighted Average Contractual Life (years)		Intrinsic Value
Options Outstanding		2.92	$	3
Options Exercisable		2.86	$	3

The intrinsic value is based on the share price of $6.55 at June 30, 2021.

For outstanding stock options, the Company calculated the fair value of each option grant on the date of grant using the Black-Scholes option-pricing model. Because the Company’s employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, the existing models may not necessarily provide a reliable single measure of the fair value of the employee stock options. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility and expected option life.  

The dividend yield rate is calculated by dividing the Company’s annual dividend by the closing price on the grant date. The risk-free interest rate is based on the U.S. Treasury yields with a remaining term that approximates the expected life of the options granted.  The expected volatility is based on a five-year historical period of the Company’s stock price. The expected life for options granted is based on historical data of employee exercise performance.  The Company records expense based on the graded vesting method.  

Performance-Based Equity Awards

Short-Term Incentive Plan

Incentive compensation earned by executives and key managers under the Company’s 2021 Short-Term Incentive Plan (“STIP”) will be settled 50% in cash and 50% in shares of the Company’s stock as was the case with the 2020 STIP.  Under both the 2021 STIP and 2020 STIP, payouts could be earned based on annual revenue and adjusted EBITDA targets.  No shares were earned under the 2020 STIP because the Company did not exceed the revenue or EBITDA thresholds.  

Long-Term Incentive Plan

22

The Company grants performance-based awards to executives and key managers to encourage sustainable growth, consistent earnings, and management retention.  Based on the fair value of the shares on the grant date, the Company records stock compensation expense over the performance period based on the estimated achievement of the award.

The following table summarizes the performance award activity:

	Awards at Target		Weighted Average Fair Value
Unvested Performance Awards - December 31, 2020		316,726	$	6.84
Awards granted		187,864		8.15
Unvested Performance Awards - June 30, 2021		504,590	$	7.33

The Company granted performance awards under its long-term incentive plan to executives and key managers in February 2021 (“2021 LTIP”).  The performance period for the 2021 LTIP is from January 1, 2021 through December 31, 2023.  At target, the total fair market value of the award was $1.5 million based on the average share price of $8.15 on the grant date.  On the award date, the aggregate number of shares that could be earned at target was 187,864 and the maximum number of aggregate shares that could be earned was 328,762.  

Under the 2021 LTIP and similar plans from 2019 and 2020, shares of the Company’s stock can be earned based on achievement of a three-year revenue growth target with a penalty if a certain adjusted EBITDA level is not maintained.  If the Company achieves less than the target growth over the performance period, the participant will receive fewer shares than the target award, determined on a straight-line basis. If the Company achieves greater than the target growth, the participant will receive more shares than the target award on an accelerated basis. Participants are required to be in service at the determination date of the award following the end of the performance period in order to receive the award. Shares earned will be fully vested shares.  The Company records stock compensation expense over the performance period based on the Company’s estimate of the aggregate number of shares that will be earned under the incentive plan.     

The following table summarizes the active performance-based long-term incentive plans at June 30, 2021:

			Number of Shares
	Share Price		That Could Be Earned:
LTIP award	on Grant Date		Target		Maximum		Performance Period
2019 LTIP	$	5.27		171,437		295,325	January 1, 2019 through December 31, 2021
2020 LTIP	$	8.70		145,289		254,256	January 1, 2020 through December 31, 2022
2021 LTIP	$	8.15		187,864		328,762	January 1, 2021 through December 31, 2023
				504,590		878,343

Employee Stock Purchase Plan (“ESPP”)

The ESPP enables eligible employees to purchase common stock at the lower of 85% of the fair market value of the common stock on the first or last day of each offering period.  Each offering period is approximately six months.     

Based on the 15% discount and the fair value of the option feature of the ESPP, it is considered compensatory.  Compensation expense is calculated using the fair value of the employees’ purchase rights under the Black-Scholes model.

The Company calculated the fair value of each employee stock purchase grant on the date of grant using the Black-Scholes option-pricing model using the following assumptions:

	Employee Stock Purchase Plan
	2021			2020
Dividend yield		3.1	%		4.1	%
Risk-free interest rate		0.1	%		0.1	%
Expected volatility		48	%		44	%
Expected life (in years)		0.5			0.5

The dividend yield rate was calculated by dividing the Company’s annual dividend by the closing price on the grant date.  The risk-free interest rate was based on the U.S. Treasury yields with a remaining term that approximates the expected life of the options granted.  The volatility was based on a five-year historical period of the Company’s stock price.  The expected life was based on the offering period.

Board of Director Equity Awards

The Company grants equity awards to members of its Board of Directors as an annual retainer and for committee service. These awards are shares of the Company’s stock that vest upon issuance or, in some cases, one year after issuance. In addition, new directors receive a one-time grant that vests over three years. In May 2021, the Company issued 61,186 shares to directors for their annual retainer and committee services of which 49,652 shares vested immediately upon issuance, with the remainder vesting one year after issuance. The fair value of the service based restricted shares for directors that vested during the six months ended June 30, 2021 was $0.3 million.

The following table summarizes the director awards activity:

	Shares			Weighted Average Fair Value
Outstanding - December 31, 2020		2,416		$	6.90
Shares awarded		61,186			6.57
Shares vested		(52,068	)		6.65
Outstanding - June 30, 2021		11,534		$	6.57

 Employee Withholding Taxes on Stock Awards

For ease in administering the issuance of stock awards, the Company holds back shares of vested restricted stock awards, stock option exercises and short-term and long-term incentive plan stock awards for the value of the statutory withholding taxes.  For everyone receiving a share award, the Company redeems the shares it computes as the value for the withholding tax and remits this amount to the appropriate tax authority.  For withholding taxes related to stock awards, the Company paid $0.8 million and $1.1 million during the six months ended June 30, 2021 and 2020, respectively.

Stock Repurchases

On November 6, 2019, the Board of Directors approved a share repurchase program (“2019 Repurchase Plan”), which was reauthorized on March 10, 2020 under the 2019 Repurchase Plan, the Company was authorized to repurchase up to $7.0 million of its common stock through the end of 2020.  The Company spent $2.0 million to repurchase 375,046 shares at an average price of $5.36 during the three months ended March 31, 2020.  Due to uncertainties related to the COVID-19 pandemic and to protect the Company’s cash position, on April 1, 2020 the Board of Directors approved the termination of the 2019 Repurchase Plan.  

On November 4, 2020, the Board of Directors approved a $5.0 million share repurchase program (“2020 Repurchase Plan”). The Company spent $1.8 million to repurchase 288,573 shares at an average price of $6.30 during the three months ended December 31, 2020 and the Company spent $0.7 million during the six months ended June 30, 2021 to repurchase 112,951 shares at an average price of $6.49.  The Company retired all repurchased shares.

10. Commitments and Contingencies

China Restructuring

On August 7, 2019, the Company’s Board of Directors approved a transition plan for the Company’s China manufacturing operations. As part of the plan, the Company is transitioning high-volume manufacturing from its Tianjin, China facility to contract manufacturers in China and elsewhere in order to reduce fixed costs in China, optimize the cost structure of the antenna product line, and create flexibility in antenna manufacturing due to the uncertainty of the lease of the current manufacturing premises, as described below. For the year ended December 31, 2020, the Company incurred restructuring expenses of $0.1 million for employee severance related to the separation of 12 employees and for the year ended December 31, 2019, the Company incurred restructuring expenses of $0.5 million for employee severance and related benefits related to the separation of 84 employees.   Severance costs were paid from the Company’s cash in its China bank accounts.      

On October 8, 2020, the lease of the premises on which the Company’s China manufacturing operations are conducted expired and the renewal is pending and uncertain. The Company has been notified that the Chinese Party Central Committee and the State Council are accelerating the layout optimization and transformation of the industrial park in which the Company’s leased premises is located and, accordingly, leases and lease extensions for all premises in the industrial park have been suspended and rent collection has been postponed.  The Company has not received an indication of the likelihood of approval of its lease extension.  However, should the lease ultimately be extended, rent will be due for the period of the lease suspension.  As a result of the uncertainty regarding the Tianjin Lease (as defined in Note 11) renewal, the Company is refining its transition plan for the manufacturing activities conducted on the leased premises. As part of the refined transition plan, the Company will retain a group of employees in Tianjin, China, but will reduce additional headcount in Tianjin and incur additional restructuring charges..  The Company expects the transition to be substantially completed by the end of the 2021 fiscal year.

The following table summarizes the restructuring activity during the six months ended June 30, 2021 and the status of the reserves at June 30, 2021:

			Lease
	Severance		Termination			Total
Balance at December 31, 2020	$	0	$	15		$	15
Restructuring expense		60		0			60
Payments made		0		(15	)		(15	)
Balance at June 30, 2021	$	60	$	0		$	60

The restructuring liability is recorded in accrued liabilities on the condensed consolidated balance sheet at June 30, 2021 and December 31, 2020.

Warranty Reserve and Sales Returns

The Company allows its major distributors and certain other customers to return unused product under specified terms and conditions.  The Company accrues for product returns based on historical sales and return trends.  The refund liability related to estimated sales returns was $0.2 million and $0.1 million at June 30, 2021 and December 31, 2020, respectively, and is included within accrued liabilities on the accompanying condensed consolidated balance sheets.

11. Leases

The Company has operating leases for facilities and finance leases for office equipment.  Leases with an initial term of 12 months or less are not recorded in the balance sheet.  The Company determines if an arrangement is a lease at inception of a contract.

Right of Use (“ROU”) assets represent the Company's right to use an underlying asset during the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the net present value of fixed lease payments over the lease term. The Company's lease term is deemed to include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. ROU assets also include any advance lease payments made and exclude lease incentives. As most of the Company's operating leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments on a collateralized basis. Finance lease agreements generally include an interest rate that is used to determine the present value of future lease payments. Operating fixed lease expense and finance lease depreciation expense are recognized on a straight-line basis over the lease term.

The Company's lease cost for the three and six months ended June 30, 2021 and 2020, respectively, included the following components:

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Operating lease costs	$	115	$	165	$	212	$	410
Short-term lease costs		41		14		82		27
Variable lease costs		2		0		4		2

 On March 5, 2020, PCTEL (Tianjin) Wireless Telecommunications Products, Co. Ltd., a wholly owned subsidiary of the Company (“PCTEL Tianjin”), entered into a letter agreement with Wang Zhuang Village Committee of Tianjin, China (the “Letter Agreement”) specifying the terms for extension of the lease of the premises on which PCTEL Tianjin currently conducts its manufacturing activities in Tianjin, China (the “Tianjin Lease”) to October 2022. The Letter Agreement did not, however, effect the lease extension. The Tianjin Lease expired on October 8, 2020 without extension.  On October 16, 2020, the Wang Zhuang Village Committee issued a notice informing PCTEL Tianjin that the Chinese Party Central Committee and the State Council are accelerating the layout optimization and transformation of the industrial park in which the leased premises is located, and accordingly leases and lease extensions for all premises in the industrial park have been suspended and rent collection has been postponed. The letter indicates that if the Tianjin Lease extension is subsequently approved, the rent for the period from October 9, 2020 to the date of the Tianjin Lease extension (the “Intervening Period”) will then be due and payable.  In July 2021, PCTEL Tianjin received an indication from local Chinese authorities that the Tianjin lease extension is likely to be approved for a period of October 10, 2020 to December 31, 2021 and lease negotiations have commenced. However, based upon past practices and verbal assurances, the Company believes that PCTEL Tianjin will have not less than 30 days to vacate the leased premises if the Lease Extension is not approved.

As part of the acquisition of Smarteq on April 30, 2021, the Company assumed an office lease and an automotive lease. The office in Kista, Sweden has 4,080 square feet used for engineering, sales, and administration with a lease term ending July 31, 2023.  On the acquisition date, the Company recorded $0.2 million for each of the right-of-use assets and the lease liabilities.

12. Borrowings

As part of the Smarteq acquisition, the Company assumed a five-year loan of approximately $0.1 million with an interest rate of 0.57%.  The loan was part of a program from the French Ministry of Economy and Finance as financial support for French businesses during the COVID-19 pandemic.  The loan is denominated in Euros. Payment of the interest and principal on the loan is deferred until June 2022 and the loan term ends in May 2026. The amount due within one year is $2, and the remainder is due in equal monthly payments thereafter.

13. Income Taxes

The Company recorded income tax expense of $12 and $16 for the six months ended June 30, 2021 and 2020, respectively. The expense recorded for the six months ended June 30, 2021 and 2020 was lower than the statutory rate of 21% because the Company has a full valuation allowance on its deferred tax assets. The Company’s valuation allowance is due to the uncertainty regarding the utilization of the deferred tax assets.

The Company had deferred tax assets net of deferred tax liabilities of $15.2 million at June 30, 2021 and $12.9 million at December 31, 2020. The deferred tax assets consisted of domestic deferred tax assets of $12.1 million, China deferred tax assets of $0.8 million, and $2.3 million of deferred tax assets for Sweden. The Company’s gross deferred tax assets consist of federal and state net operating losses (“NOLs”), credits, and timing differences. As part of the acquisition of Smarteq, the recorded deferred tax assets of $2.3 million associated with net operating losses inventory reserves and recorded tax liabilities associated with acquired intangible assets.  Because of the objective evidence of cumulative three-year losses and uncertainty associated with the COVID-19 pandemic, the Company recorded a full valuation allowance on the deferred tax assets.  

The Company’s federal NOLs generated in 2018 and future periods will not expire, and the Company’s NOLs and credits generated as of December 31, 2017 have a finite life primarily based on the 20-year carry forward of federal net operating losses. The timing differences have a ratable reversal pattern over 12 years. On a regular basis, the Company evaluates the recoverability of deferred tax assets and the need for a valuation allowance. Such evaluations involve the application of significant judgment. The Company considers multiple factors in its evaluation of the need for a valuation allowance. The Company generated book and tax income during 2020 but generated book losses for the six months ended June 30, 2021. The Company believes its financial outlook remains positive but because of difficulties with forecasting financial results historically, and due to the uncertainties associated with the COVID-19 pandemic, the Company maintained a full valuation allowance on its deferred tax assets at June 30, 2021 and December 31, 2020.  

The analysis that the Company prepared to determine the valuation allowance required significant judgment and assumptions regarding future market conditions as well as forecasts for profits, taxable income, and taxable income by jurisdiction. Due to the sensitivity of the analysis, changes to the assumptions in subsequent periods could have a material effect on the valuation allowance.

The Company files a consolidated federal income tax return, income tax returns with various states, and foreign income tax returns in various foreign jurisdictions. The Company’s U.S. federal tax returns remain subject to examination for 2017 and subsequent periods. The Company’s U.S. state tax returns remain subject to examination for 2015 and subsequent periods. The Company’s foreign tax returns remain subject to examination for 2011 and subsequent periods. The Company’s gross unrecognized tax benefit was $0.8 million at June 30, 2021 and December 31, 2020.

28

On March 27, 2020, the “Coronavirus Aid, Relief and Economic Security Act” (CARES Act) was signed into law. The CARES Act includes provisions relating to refundable payroll tax credits, deferment of the employer portion of certain payroll taxes, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property.  Under the CARES Act, the Company is deferring the employer portion of social security taxes and will apply for a refund of its Alternative Minimum Tax credit.  As of June 30, 2021, the Company has deferred $0.5 million of payroll taxes. The payroll taxes will be deferred until the due dates of December 31, 2021 and December 31, 2022.  The Company records a deferred tax asset for the payroll tax liability due by December 31, 2022 that is not deductible in 2021 for income tax purposes.

15. Revenue from Contracts with Customers

Under Topic 606, a contract with a customer is an agreement which both parties have approved, that creates enforceable rights and obligations, has commercial substance, and specified payment terms, and for which collectability is probable. Once the Company has entered into a contract, it is evaluated to identify performance obligations. For each performance obligation, revenue is recognized as control of promised goods or services transfers to the customer in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services. The amount of revenue recognized takes into account variable consideration, such as returns and volume rebates.  A majority of the Company’s revenue is short cycle in nature with shipments within one year from order. The Company's payment terms generally range between 30 to 90 days.

All of the Company’s revenue relates to contracts with customers.  The Company’s accounting contracts are from purchase orders or purchase orders combined with purchase agreements.  The majority of the Company’s revenue is recognized on a “point-in-time” basis and a nominal amount of revenue is recognized “over time”.  For the sale of antenna products and test & measurement products, the Company satisfies its performance obligations generally at the time of shipment or upon delivery based on the contractual terms with its customers.  For products shipped on consignment, the Company recognizes revenue upon delivery from the consignment location.  For its test & measurement software tools, the Company has a performance obligation to provide software maintenance and support for one year.  The Company recognizes revenues for the maintenance and support over this period.  

The Company considers shipping and handling performed by the Company as fulfillment activities.  Amounts billed for shipping and handling are included in revenues, while costs incurred for shipping and handling are included in cost of revenues.  The Company excludes taxes from the transaction price.  Cost of contracts include sales commissions.  The Company expenses the cost of contracts when incurred because the amortization period is one year or less.

The Company allows its major distributors and certain other customers to return unused product under specified terms and conditions.  The Company estimates product returns based on historical sales and return trends and records a corresponding refund liability.  The refund liability was $0.2 million and $0.1 million at June 30, 2021 and December 31, 2020 respectively and is included within accrued liabilities in the accompanying condensed consolidated balance sheets.  The Company records an asset based on historical experience

30

for the amount of product it expects to return to inventory as a result of customer returns, which is recorded in inventories in the accompanying condensed consolidated balance sheets.  The product return asset was $0.1 million at June 30, 2021 and December 31, 2020.

There were no contract assets at June 30, 2021 or December 31, 2020. The Company records contract liabilities for deferred revenue and customer prepayments.  Contract liabilities are recorded in accrued liabilities in the accompanying condensed consolidated balance sheets.  The contract liability was $0.5 million and $0.4 million at June 30, 2021 and December 31, 2020, respectively.  The Company recognized revenue of $0.5 million and $0.4 million during the six months ended June 30, 2021 and 2020, respectively, related to contract liabilities that existed at the beginning of the period.   

16. Subsequent Events

The Company evaluates subsequent events occurring between the most recent balance sheet date and the date that the financial statements are available to be issued in order to determine whether the subsequent events are to be recorded and/or disclosed in the Company’s financial statements and footnotes. The financial statements are considered to be available to be issued at the time that they are filed with the SEC.  There were no other subsequent events or transactions that required recognition or disclosure in the unaudited interim condensed consolidated financial statements.

COVID-19 Update

The global COVID-19 outbreak and increased business uncertainty had an adverse impact on our financial results during 2020 through global shutdowns and supply chain and operational disruptions. We took a variety of actions during 2020 to help mitigate the financial impact, including executing temporary cost savings measures, reducing our capital spending, and proactively managing our working capital. For test & measurement products, we experienced higher revenues in the first half of 2021 compared to the prior year. Demand for our antennas and Industrial IoT devices is taking longer to recover, but revenue improvement is forecasted during the second half of 2021.  The global recovery in demand has had impacts on our business, including increased material cost inflation, logistics costs increases and in some cases component part shortages. Currently, our expectation is that the impacts of material cost inflation and logistics constraints will continue into the second half of 2021.

Our foremost focus continues to be the health and safety of our employees.  We continue to maintain our enhanced health and safety protocols at our facilities and are encouraging our employees to obtain vaccination. We will continue to closely monitor the risks posed by COVID-19 and the guidance from relevant authorities. We will adjust our practices accordingly, as we have throughout the pandemic.

Second Quarter Overview

Revenues for the three months ended June 30, 2021 were $21.7 million, an increase of 9.3% compared to $19.8 million for the same period in 2020.  By product line, revenues increased by $0.3 million (4.8%) to $6.4 million for test & measurement products and increased by $1.7 million (11.9%) to $15.6 million for antennas and Industrial IoT devices. The increase in revenues for antennas and Industrial IoT devices was primarily due to the acquisition of Smarteq.  Gross profits of $9.9 million for the quarter increased by $0.4 million compared to the same period in 2020, primarily due to the revenue increases for both product lines.  Operating expense of $10.1 million was $1.6 million higher than in the second quarter 2020. The increase results from inclusion of two months of Smarteq’s operating expenses and employee-related costs, including salaries and incentive compensation expenses. Operating expenses for the second quarter 2020 were lower due, in part, to measures the Company took at the beginning of the pandemic to control costs, including temporary reductions in salaries, travel, and other discretionary spending.  The net impact of these changes resulted in a loss before tax of $0.2 million in the second quarter 2021 compared to income before tax of $1.2 million for the second quarter of 2020.

Revenues for the six months ended June 30, 2021 were $39.4 million, an increase of 5.5%, compared to $37.3 million for the same period in 2020. By product line, revenues increased by $0.4 million (3.4%) to $12.6 million for test & measurement products and increased by $1.9 million (7.5%) to $27.3 million for antennas and Industrial IoT devices. The increase in revenues for test & measurement products was driven by growth in products for public safety applications.  The increase in revenues for antennas and Industrial IoT devices was primarily due to the acquisition of Smarteq. Gross profits of $18.3 million increased by $0.5 million compared to the same period in the prior year due to the higher revenues in both product lines. Operating expenses of $19.1 million was $1.6 million higher than the same period in the prior year. The increase results from inclusion of two months of Smarteq’s operating expenses and employee-related costs, including salaries and incentive compensation expenses in addition to higher restructuring expenses and intangible amortization expenses related to the Smarteq acquisition. Operating expenses for the second quarter 2020 were lower due, in part, to measures the Company took at the beginning of the pandemic to control costs, including temporary reductions in salaries, travel, and other discretionary spending. The net impact of these changes resulted in a decrease in income before tax of $1.3 million for the six months ended June 30, 2021 compared to the same period in 2020. Net loss before tax was $0.8 million for the six months ended June 30, 2021 and net income was $0.5 million for the six months ended June 30, 2020.

Our cash and investments decreased by $7.1 million during the second quarter 2021 primarily due to the cash paid for our acquisition of Smarteq Wireless Aktiebolag. See the description below for additional details on the acquisition.  As of June 30, 2021, we had cash and investments of $33.4 million and debt of $0.1 million.

Smarteq Acquisition

33

On April 30, 2021, we acquired all the outstanding stock of Smarteq Wireless Aktiebolag, a Swedish company based in Kista, Sweden that designs antennas for specialized industrial IoT and vehicular applications (“Smarteq”), pursuant to a Share Sale and Purchase Agreement between PCTEL and Allgon Aktiebolag, a Swedish company and holder of the outstanding stock of Smarteq (the “Agreement”). Smarteq owns all the outstanding stock of SAS Smarteq France, which engages in sales of Smarteq products. PCTEL paid cash consideration of SEK 56.8 million ($6.8 million) at the close of the transaction, all of which was provided from PCTEL’s existing cash.  We believe the acquisition of Smarteq will provide a strong local presence, expertise, and channel partners to accelerate our growth in Europe, as well as a complementary portfolio of products for our Industrial IoT and intelligent transportation customers worldwide. The results for Smarteq are combined with the Company’s antenna and Industrial IoT vice product line.

Research and development expenses were higher by $0.2 million and $0.3 million for the three and six months ended June 30, 2021 compared to the same period in 2020 primarily due to expenses related to Smarteq.

Sales and marketing expenses include costs associated with the sales and marketing employees, product line management, and trade show expenses.

Sales and marketing expenses increased $1.0 million for the three months ended June 30, 2021 compared to the same period in 2020 due to two months of sales and marketing expenses for Smarteq of $0.2 million, higher incentive compensation expense of $0.3 million, employee related costs of $0.2 million, marketing expenses of $0.1 million, travel of $0.1 million, and also due to the fact that the second quarter 2020 included a bad debt recovery for $0.1 million.

Sales and marketing expenses increased $0.6 million for the six months ended June 30, 2021 compared to the same period in 2020 as expenses associated with the acquisition of Smarteq of $0.2 million, higher incentive compensation expense of $0.2 million, and employee related costs of $0.3 million offsetting lower travel expenses of $0.2 million and lower other sales and marketing expenses of $0.1 million.

General and administrative expenses include costs associated with general management, finance, human resources, IT, legal, public company costs, and other operating expenses to the extent not otherwise allocated to business segments.

General and administrative expenses increased by $0.4 million for the three months ended June 30, 2021 compared to the same period in 2020 due to expenses for the Smarteq business, non-recurring professional fees associated with the acquisition of Smarteq, and higher employee costs related to salaries and cash-based incentive compensation programs.

General and administrative expenses increased by $0.7 million for the six months ended June 30, 2021 compared to the same period in 2020 due to expenses for the Smarteq business, non-recurring professional fees incurred associated with the acquisition of Smarteq, and higher employee costs related to salaries and cash-based incentive compensation programs.

Amortization of intangible assets within operating expenses was $55 for the three and six months ended June 30, 2021.  This relates to intangible assets for the Smarteq acquisition.  The amortization of intangible assets of $33 that was recorded during the six months

36

ended June 30, 2020 related to intangible assets that became fully amortized during the first quarter 2020. There was $0 of intangible asset amortization during the three months ended June 30, 2020.

Restructuring expenses relate to the transition of manufacturing operations from our Tianjin, China facility to contract manufacturers.  Restructuring expenses of $60 for the three and six months ended June 30, 2021 consisted of employee severance and payroll related costs associated with the termination of five employees in Tianjin.  During 2021, we expect to reduce additional headcount in Tianjin and incur additional restructuring charges for severance and non-cash costs. We expect additional restructuring expense of between $0.8 million and $1.0 million in 2021 primarily for employee terminations but also for other non-cash related expenses.  We expect the transition to be substantially completed by the end of the 2021 fiscal year.

Restructuring expenses of $0.1 million for the six months ended June 30, 2020 consisted of employee severance and payroll related costs associated with the termination of ten employees in Tianjin.

Expense for income taxes	$	7		$	8		$	12		$	16
Effective tax rate		(4.3	)%		0.7	%		(1.5	)%		3.1	%

We recorded income tax expense of $12 and $16 for the six months ended June 30, 2021 and 2020, respectively. The expense recorded for the six months ended June 30, 2021 and 2020 differed from the Federal statutory rate of 21% primarily because we have a full valuation allowance on our deferred tax assets. The full valuation allowance is due to the uncertainty regarding the utilization of the deferred tax assets.

On a regular basis, we evaluate the recoverability of deferred tax assets and the need for a valuation allowance. Such evaluations involve the application of significant judgment. We considered multiple factors in our evaluation of the need for a valuation allowance. The full valuation allowance against our deferred tax assets was $15.3 million at June 30, 2021 and $12.9 million at December 31, 2020. The deferred tax assets consist of domestic deferred tax assets of $12.1 million and foreign deferred tax assets of $3.2 million. As part of the Smarteq acquisition, we recorded $2.4 million of net deferred tax assets. While the Company expects book and tax profits in 2021 and future periods, Smarteq has recorded a three-year cumulative tax loss.  Based on this objective evidence and uncertainty associated with the COVID-19 pandemic, the Company recorded a full valuation allowance on the opening balance sheet for Smarteq.

We recorded pretax book income during 2020 and believe our financial outlook remains positive.  However, the COVID-19 pandemic has created a high level of uncertainty. Due to this uncertainty, as well as difficulties with forecasting financial results historically, we maintained a full valuation allowance on our deferred tax assets at June 30, 2021.  The analysis that we prepared to determine the valuation allowance required significant judgment and assumptions regarding future market conditions as well as forecasts for profits, taxable income, and taxable income by jurisdiction. Due to the sensitivity of the analysis, changes to the assumptions in subsequent periods could have a material effect on the valuation allowance. See Note 13 to the condensed consolidated financial statements for more information related to income taxes.

Net Loss

We recorded a net loss of $0.2 million for the three months ended June 30, 2021 compared to net income of $1.2 million for the same period in 2020, as higher operating expenses offset higher gross profits.  Operating expenses were higher by $1.6 million as we spent more in all functional areas, and we recorded higher restructuring expenses and intangible amortization expense for the intangible assets acquired from Smarteq.  

We recorded a net loss of $0.8 million for the six months ended June 30, 2021 compared to net income of $0.5 million for the same period in 2020, as the impact of higher operating expenses and lower other income and expense offset the higher gross profits from higher revenues. The increase in gross profit was a result of an increase in gross profit for both test & measurement products and antennas and Industrial IoT devices.  Operating expenses were higher by $1.6 million as we spent more in all functional areas, and we recorded intangible amortization expense for the intangible assets acquired from Smarteq and we recorded higher restructuring expenses.  Other income and expense was lower by $0.3 million because primarily because of lower interest income due to lower interest rates.

Overview

Our primary source of liquidity is cash provided by operations, with short-term swings in liquidity supported by a significant balance of cash and short-term investments.  The balance has fluctuated with cash from operations, acquisitions and divestitures, payment of dividends and the repurchase of our common shares.

Within operating activities, we are historically a net generator of operating funds from our income statement activities.  During the six months ended June 30, 2021, our balance sheet provided operating funds.  In periods of expansion, we expect to use cash from our balance sheet.

Within investing activities, capital spending historically ranges between 2.0% and 4.0% of our revenues and the primary use of capital is for manufacturing, engineering, and product development.  We historically have made significant transfers between investments and cash as we rotate our large cash balances and short-term investment balances between money market funds, which are accounted for as cash equivalents, and other investment vehicles.  We have a history of supplementing our organic revenue with acquisitions of product lines or companies, resulting in significant uses of our cash and short-term investment balances from time to time.  We used $6.3 million, net of cash acquired for the purchase of Smarteq in April 2021.  We expect the historical trend for capital spending and the variability caused by moving money between cash and investments and periodic merger and acquisition activity to continue in the future.

Within financing activities, we have historically generated funds from the exercise of stock options and proceeds from the issuance of common stock through the ESPP. We have historically used funds to issue dividends and we periodically repurchase shares of our common stock through share repurchase programs.  We used $3.8 million for the repurchase of shares during the full year 2020 and $0.7 million for the repurchase of shares during the six months ended June 30, 2021. Share repurchases were funded with cash on hand. As of June 30, 2021, there was $2.5 million remaining under our repurchase program.  

38

At June 30, 2021, our cash, cash equivalents, and investments were approximately $33.4 million, and we had working capital of $50.0 million.  As the COVID-19 pandemic continues to evolve, we are proactively managing our costs and our working capital in order to protect our financial position and maintain our workforce. Management believes our cash and investments provide adequate liquidity and working capital to support our operations given our historic ability to generate free cash flow (cash flow from operations less capital spending) and our low level of debt.

Operating Activities:

Operating activities generated $3.1 million of cash during the six months ended June 30, 2021.  We generated $2.4 million of cash from our statement of operations activities and $0.7 million from the balance sheet. The balance sheet was a net source of cash as accounts receivable collections offset the impact of higher inventories. Accounts receivable decreased by $1.3 million primarily due to lower days sales outstanding on outstanding invoices. Inventories increased for both product lines by approximately $1.1 million in order to maintain customer service levels while the Company manages supply chain delays and component shortages.  

Operating activities generated $7.1 million of cash during the six months ended June 30, 2020.  We generated $3.6 million of cash from our statement of operations activities and $3.5 million from the balance sheet.  The balance sheet was a net source of cash as reductions in accounts receivable and inventories as well as an inflation in our accounts payable balance offset payments for accrued liabilities.  Accounts receivable decreased by $2.1 million primarily because revenues declined by $3.1 million from the through months ended June 30, 2020 compared to the three months ended December 31, 2019.  Accrued liabilities decreased by $1.2 million primarily because we paid $2.6 million in the first quarter for cash bonuses earned under our 2019 short-term incentive plan.  

Investing Activities:

Our investing activities provided $2.7 million of cash during the six months ended June 30, 2021.  In April 2021, the Company used $6.3 million for the purchase of Smarteq, net of cash acquired.  During the six months ended June 30, 2021, redemptions and maturities of our investments provided $26.3 million in funds and we rotated $16.1 million of cash into new investments.  We used $1.3 million for capital expenditures during the six months ended June 30, 2021.  

Our investing activities used $3.0 million of cash during the six months ended June 30, 2020.  During the six months ended June 30, 2020, redemptions and maturities of our short-term investments provided $25.8 million in funds and we rotated $26.3 million of cash into new investments.  We used $2.4 million for capital expenditures during the six months ended June 30, 2020.  We used cash of $1.4 million for leasehold improvements and other facility related equipment for the facility which opened in January 2020. During the six months ended Jun 30, 2020 we received $1.0 million in tenant allowances for the Clarksburg facility. This amount is reflected in operating activities.

Financing Activities:

We used $3.2 million in cash for financing activities during the six months ended June 30, 2021.  We also used $2.0 million for quarterly cash dividends, we used $0.7 million for share repurchases, and $0.8 million for payroll taxes related to stock-based compensation in this period.  The tax payments related to restricted stock awards.  Proceeds from the issuance of common stock for our ESPP provided $0.4 million for the six months ended June 30, 2021.

We used $4.7 million in cash for financing activities during the six months ended June 30, 2020. We used $2.1 million for quarterly cash dividends paid, and $2.0 million for share repurchases. We used $1.1 million for payroll taxes related to stock-based compensation. The tax payments related to restricted stock awards and the short-term incentive plan. Proceeds from the issuance of common stock for our ESPP provided $0.5 million for the six months ended June 30, 2020. On April 16, 2020, we received a $3.5 million paycheck protection program (“PPP”) loan from the Small Business Administration. Based upon subsequent guidance regarding PPP loan eligibility, we returned the funds on April 30, 2020.

Off-Balance Sheet Arrangements

None.

Contractual Obligations and Commercial Commitments

We had purchase obligations of $12.6 million and $10.9 million at June 30, 2021 and December 31, 2020, respectively, for the purchase of inventory as well as for other goods and services in the ordinary course of business.  Balances for purchases currently recognized as liabilities on the balance sheet are excluded.

We had a liability of $0.9 million and $0.8 million related to income tax uncertainties at June 30, 2021 and December 31, 2020, respectively.  We do not know the timing of the settlement of this liability.

39

Critical Accounting Policies and Estimates

We use certain critical accounting policies as described in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates” of the 2020 Form 10-K.  There have been no material changes in any of our critical accounting policies since December 31, 2020.  See Note 1 to the Condensed Consolidated Financial Statements for a discussion of recent accounting pronouncements.  

Item 3: Quantitative and Qualitative Disclosures about Market Risk

See our 2020 Form 10-K (Item 7A).  As of June 30, 2021, there have been no material changes in this information.

Item 4: Controls and Procedures

Our management evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can only provide reasonable assurance of achieving the desired control objectives.  Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of the end of the period covered by this report, our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act, as amended (the “Exchange Act”) were effective to ensure that information we are required to disclose in reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure, and that such information is recorded, processed, summarized, and reported within time periods specified in the Securities and Exchange Commission rules and forms.  

In connection with the evaluation required by Rule 13a-15(d), management, with the participation of the Chief Executive Officer and Chief Financial Officer, has identified that there have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We have not experienced any material impact to our internal controls over financial reporting despite transitioning nearly all of our administrative workforce to a remote working environment as a result of the COVID-19 pandemic. We are continually monitoring and assessing the impact of COVID-19 on our internal controls to minimize the impact to their design and operating effectiveness.

PART II - OTHER INFORMATION

Item 1: Legal Proceedings

We may, from time to time, be the subject of various pending or threatened legal actions in the ordinary course of our business. All such matters are subject to many uncertainties and outcomes that are not predictable with assurance. To our knowledge, as of June 30, 2021, there were no claims or litigation pending against the Company that would be reasonably likely to have a material adverse effect on our consolidated financial position, results of operations or liquidity.

Item 1A: Risk Factors

See our 2020 Form 10-K (Item 1A).  As of August 9, 2021, there have been no material changes in this information other than the risk factor below.

We face risks as a result of the acquisition of Smarteq Wireless Aktiebolag.

On April 30, 2021, we completed our acquisition of Smarteq Wireless Aktiebolag (“Smarteq”). As a result of the acquisition, we face various risks, including, among others, the following:

• difficulty in integrating Smarteq’s products, engineering and technology, operations, sales and distribution channels, internal accounting controls, or work force with our existing business;

• greater than anticipated costs related to the integration of Smarteq’s business and operations into our existing business and operations;

• diversion of resources and management attention from other strategic activities;

• disruption of our on-going business and of Smarteq’s business, operations, and relationships with contract manufacturers, suppliers, service providers, customers, and employees;

• difficulty in realizing the potential financial or strategic benefits of the acquisition of Smarteq;

• difficulty in maintaining uniform standards, controls, procedures, and policies;

• tax, employment, logistics, and other related issues unique to Smarteq or organizations like Smarteq;

• possible impairment of relationships with employees, suppliers, and customers as a result of integration of the Smarteq business and our existing business;

• possible impairment of assets related to goodwill resulting from the acquisition of Smarteq, and reductions in our future operating results from amortization of intangible assets.

We are dependent on the accuracy and completeness of statements and disclosures made by Smarteq and its representatives. We did not control and may be unaware of activities of Smarteq before the acquisition relating to, among other things, intellectual property, litigation or disputes, information security vulnerabilities, violations of laws, policies, rules and regulations, commercial disputes, tax liabilities, and other liabilities.  

Any of the risks described above could have a material adverse impact on our business, financial condition, results of operations, or prospects.

[Employee Name and Address]

Subject:  Enhancement of Severance Benefit

Dear [Name of Employee]:

I am pleased to inform you of the approval by the Board of Directors of PCTEL, Inc. (the “Company”) on May 27, 2021 of the enhancement of the severance benefit provided to you pursuant to the severance benefit letter between you and the Company dated [insert date] (the “Prior Severance Benefits Letter”) related to continuation coverage pursuant to COBRA (as defined below). Upon the conditions set forth below, the Company will pay the entire cost of COBRA premiums for the period indicated rather than requiring you to continue to pay the portion thereof equivalent to the portion employees pay for their health insurance benefits. In order to receive this enhanced benefit, please execute this severance benefits letter agreement (“Letter Agreement”) which will supersede the Prior Severance Benefits Letter. You are hereinafter referred to as “Employee”.

Severance Benefits

(a)Termination by Company Without Cause and Apart From Change of Control. If, either prior to the occurrence of a Change of Control or after the twelve (12) month period following a Change of Control, Employee's employment is terminated (A) involuntarily by the Company for reasons other than Cause, death or Disability, or (B) by Employee pursuant to a Voluntary Termination for Good Reason, then Employee shall be entitled to receive the following benefits from the Company:

(i) Salary Continuation. Employee shall continue to receive Employee's then current Base Salary for a period of twelve (12) months following Employee's termination of employment by the Company for reasons other than Cause. All such severance payments shall be paid in accordance with the Company's normal payroll practices. Such continuation of Employee's Base Salary shall be in lieu of any and all other benefits which Employee is entitled to receive on the date of Employee's termination of employment pursuant to any Company severance and benefit plans and practices or pursuant to other agreements with the Company.  Employee shall not be entitled to pro-rated payment of an annual bonus.

(ii) Benefits.  Provided that Employee receives health insurance benefits (i.e., medical, dental and/or vision) through the Company on the date of Employee’s termination by the Company for reasons other than Cause (the “Termination Date”) and elects continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), within the time period prescribed pursuant to COBRA, the Company will pay the cost of COBRA premiums for continued health coverage for Employee and any eligible dependents covered by Employee’s health insurance benefits immediately prior to the Termination Date at the same level of coverage as was provided to Employee immediately prior to the Termination Date. The Company shall continue to pay the cost of the COBRA premiums until the earlier of (A) twelve (12) months following the Termination Date, and (B) the date upon which Employee or Employee’s dependents become covered under another employer’s group health, dental and vision insurance benefit plans. For purposes of Title X of COBRA, the date of the qualifying event for Employee and his/her dependents shall be the Termination Date.  Employee agrees to notify a representative of the Human Resources Department

of the date upon which Employee or Employee’s dependents become covered under another employer’s group health, dental and vision insurance benefit plans if such date occurs prior to the end of the period specified in clause (A) above.

(iii) Partial Accelerated Vesting.  All equity awards from the Company then held by Employee shall partially accelerate, or if Employee is then holding unvested shares, Company’s right to repurchase the then-unvested shares under each such equity award shall partially lapse, with respect to the number of shares under each such award that would have become vested or been released from such repurchase right under each respective equity award if Employee’s employment with the Company had continued for an additional twelve (12) months following Employee’s effective termination date for reasons other than Cause.

(b) Termination Following a Change of Control.  If Employee’s employment is terminated within twelve (12) months following a Change of Control, the severance and other benefits to which Employee is entitled, if any, shall be governed by the Management Retention Agreement, as amended and restated (which includes the definition of Change of Control).

(c) Other Termination. If Employee's employment is terminated by the Company for Cause, or by Employee for any reason, including death or Disability but other than pursuant to a Voluntary Termination for Good Reason, then Employee shall not be entitled to receive the severance and other benefits discussed above, but may be eligible for those benefits (if any) as may then be required by law or established under the Company's severance and benefit plans and policies existing at the time of such termination.

Separation Agreement and Release.  The receipt of any severance payments or benefits pursuant to this Letter Agreement will be subject to Employee signing, delivering and not revoking a separation agreement and release of claims (in a form reasonably acceptable to the Company), provided that such separation agreement and release of claims is effective within sixty (60) days following the Termination Date.  No severance pursuant to this Letter Agreement will be paid or provided until the separation agreement and release of claims becomes effective.  If the 60^th day after the Termination Date is in the subsequent calendar year, no payment will be made prior to January 1 of such subsequent calendar year.  If Employee should die before all of the severance amounts have been paid, such unpaid amounts will be paid in a lump sum payment promptly following such event to Employee’s designated beneficiary, if living, or otherwise to the personal representative of Employee’s estate.

Section 409A Compliance.  To the extent (i) the requirements for the “short term deferral” rule and/or the “separation pay plan” rule are not satisfied, and (ii) Employee is a “specified employee” of the Company (or any successor entity thereto) within the meaning of Section 409A(a)(2)(B)(i) on the date of Employee’s termination (other than a termination due to death), then the portion of the severance payments payable to Employee, if any, under this Agreement, when considered together with any other severance payments or separation benefits that is deemed a deferral of compensation under Section 409A shall be delayed until the earlier of: (A) the date that is six (6) months and one (1) day after the date of termination, or (B) the date of Employee’s death (such date, the “Delayed Initial Payment Date”), and the Company (or the successor entity thereto) shall (x) pay to Employee a lump sum equal to the amount Employee would have otherwise received on or before the Delayed Initial Payment Date, without any adjustment on account of such delay, as if the payments had not been delayed pursuant to this section, and (y) pay the balance of the payments in accordance with any applicable payment schedules set forth herein.  Notwithstanding anything herein to the contrary, if Employee dies following her termination, but prior to the six (6) month anniversary of Employee’s Termination Date, then any payments which have been delayed in accordance with this clause will be payable in a lump sum as soon as administratively practicable after the date of Employee’s death.

Definition of Terms:

The following terms referred to in this Letter Agreement shall have the following meanings:

Base Salary. “Base Salary” shall mean an amount equal to the Employee's Company annual salaried compensation.

Cause. “Cause” shall mean:

(i) any material act (that remains uncured for thirty (30) days following written notice from the Company) which permits the Company to terminate a written employment agreement or similar arrangement between Employee and the Company, for “cause” or a substantially equivalent term as defined in such agreement or arrangement, or

(ii) in the event there is no such agreement or arrangement, or the agreement or arrangement does not define the term “cause” or a substantially equivalent term, then “Cause” means: (A) an act of personal dishonesty taken by Employee in connection with her responsibilities as an employee and intended to result in substantial personal enrichment of Employee, (B) Employee being convicted of, or a plea of nolo contendere to, a felony, (C) a willful act by Employee which constitutes gross misconduct and which is injurious to the Company, or (D) following delivery to Employee of a written demand for performance from the Company which describes the basis for the Company's reasonable belief that Employee has not substantially performed her duties, continued violations by Employee of Employee's obligations to the Company which are demonstrably willful and deliberate on Employee's part.

Change of Control. “Change of Control” is as defined in the Management Retention Agreement (as amended and restated) entered into between Company and Employee.

Disability.  “Disability” shall mean:

(i) Executive is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months;

(ii) Executive is, by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, receiving income replacement benefits for at least three (3) months under the Company’s accident and health plan; or

(iii) Executive is determined to be totally disabled by the Social Security Administration.

Voluntary Termination for Good Reason.  “Voluntary Termination for Good Reason” shall mean that Employee voluntarily resigns within thirty (30) days following the expiration of any cure period (as discussed below) after the occurrence, without Employee’s written consent, of any of the following events:  

(i) a material diminution by the Company in the Base Salary of Employee as in effect immediately prior to such reduction (other than a reduction that applies to Company officers and/or managers generally);

(ii) a material change in the geographic location at which Employee must perform service (in other words, the relocation of Employee to a facility or a location more than fifty (50) miles from Employee’s then present location); or

(iii) any other action or inaction that constitutes a material breach by the Company of this Agreement;

provided, however, that before Employee’s employment may be terminated by a Voluntary Termination for Good Reason:

(A) Employee must provide written notice to the Company, within ninety (90) days of the initial existence of the Voluntary Termination for Good Reason condition, setting forth the reasons for Employee’s intention to terminate her employment as a result of a Voluntary Termination for Good Reason; and

(B) the Company must have an opportunity within thirty (30) days following delivery of such notice to cure the Voluntary Termination for Good Reason condition.  

For the avoidance of doubt, the voluntary resignation by Employee after the occurrence of either of the following shall not constitute grounds for a “Voluntary Termination for Good Reason”:  

(1) a reduction of the Employee’s duties, title, authority or responsibilities, relative to the Employee’s duties, title, authority or responsibilities as in effect immediately prior to such reduction, as a result of (i) the Company being acquired and made part of a larger entity, (ii) a restructuring of the Company and/or its subsidiaries, or a restructuring of the Company’s employees’ functions, and/or reporting relationships; or

(2) a material reduction of the facilities or perquisites (including office space and location) available to the Employee immediately prior to such reduction.

Notwithstanding anything herein to the contrary, the Company agrees that it will not materially reduce Employee’s aggregate level of employee benefits, including bonuses, to which Employee was entitled immediately prior to such reduction with the result that Employee’s aggregate benefits package is materially reduced (other than a reduction that generally applies to Company officers and/or managers).

Please indicate your acceptance of the foregoing by signing and returning to me a copy of this Letter Agreement.  

Very truly yours,

David A. Neumann

PCTEL, Inc.

I accept and agree to the foregoing this ____ day of ___________, 2021.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Basis of Presentation

1. Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all the information and footnotes required by U.S. GAAP for complete financial statements.  In the opinion of management, all adjustments of a normal, recurring nature that are considered necessary for a fair presentation have been included.  For further information, refer to the audited consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Form 10-K”).

Throughout this Quarterly Report on Form 10-Q, including under Part 1, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” we disclose certain measures that the Company has taken in response to the macroeconomic impacts of the novel coronavirus (“COVID-19”).  The full extent to which the COVID-19 pandemic will directly or indirectly impact the Company’s business, results of operations and financial condition will depend on future developments that remain highly uncertain at this time.

Nature of Operations

PCTEL, Inc. (the “Company”) was incorporated in California in 1994 and reincorporated in Delaware in 1998. The Company is a

leading global provider of wireless technology, including purpose-built Industrial Internet of Things (“IoT”) devices, antenna systems,

and test and measurement solutions. The Company solves complex wireless challenges to help organizations stay connected, transform, and grow, and the Company has expertise in radio frequency (“RF”), digital and mechanical engineering. The Company has two businesses (antennas & Industrial IoT devices and test & measurement products) that address three market segments: Enterprise Wireless, Intelligent Transportation, and Industrial IoT.

The Company’s principal executive offices are located at 471 Brighton Drive, Bloomingdale, Illinois 60108. The telephone number at

that address is (630) 372-6800 and the website is www.pctel.com. Additional information about the Company can be obtained on the Company’s website; however, the information within, or that can be accessed through, the Company’s website, is not part of this Quarterly Report on Form 10-Q. 

Basis of Consolidation

The unaudited interim condensed consolidated financial statements of the Company include the condensed consolidated balance sheets for the period ended June 30, 2021 and December 31, 2020, the condensed consolidated statement of cash flows for the six months ended June 30, 2021 and 2020, and the condensed consolidated statements of operations, condensed consolidated statements of comprehensive (loss) income, and the condensed consolidated statements of stockholders’ equity for the three and six months ended June 30, 2021 and 2020, respectively. The interim condensed consolidated financial statements are unaudited and reflect all adjustments of a normal recurring nature that are, in the opinion of management, necessary for a fair presentation of the interim period financial statements.  The condensed consolidated balance sheet as of December 31, 2020 is derived from the audited financial statements as of December 31, 2020.  

The unaudited interim condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”).  Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted.  The significant accounting policies followed by the Company are set forth in the 2020 Form 10-K.  There were no material changes in the Company’s significant accounting policies during the three and six months ended June 30, 2021.  In addition, the Company reaffirms the use of estimates in the preparation of the financial statements as set forth in the 2020 Form 10-K.  These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the 2020 Form 10-K.  The results of operations for the period ended June 30, 2021 may not be indicative of the results for the period ending December 31, 2021.

Foreign Operations

Cross-border transactions, both with external parties and in our internal operations, result in exposure to foreign exchange rate fluctuations. We are exposed to currency risk with the Chinese Yuan due to our operations in China, and with other foreign currencies related to the acquisition of Smarteq (see Note 4) and related to suppliers and employees outside the U.S. Fluctuations could have an adverse effect on our results of operations and cash flows. We manage certain operating activities at the local level with revenues,

costs, assets, and liabilities generally being denominated in local currencies. However, our results of operations and assets and liabilities are reported in U.S. dollars and thus will fluctuate with changes in exchange rates between such local currencies and the U.S. dollar.  Gains and losses resulting from transactions originally in foreign currencies and then translated into U.S. dollars are included in the condensed consolidated statements of operations.  For the six months ended June 30, 2021, approximately 6% of revenues and 18% of expenses were transacted in foreign currencies as compared to 3% and 18% for the six months ended June 30, 2020.  Net foreign exchange losses resulting from foreign currency transactions included in other income, net were $(53) and $(18) for the three months ended June 30, 2021 and 2020, respectively.  Net foreign exchange gains(losses) resulting from foreign currency transactions included in other income, net was $(45) and $19 for the six months ended June 30, 2021 and 2020, respectively.          

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”), Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (ASU 2017-14).  This guidance eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge.  Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value.  The changes are effective for smaller reporting companies for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, and early adoption is permitted.  The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (“Topic 848”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This update provides optional expedients and exceptions for applying generally accepted accounting principles to certain contract modifications and hedging relationships that reference London Inter-bank Offered Rate (LIBOR) or another reference rate expected to be discontinued. Topic 848 is effective upon issuance and generally can be applied through December 31, 2022.  The Company is currently evaluating the impact of Topic 848 on the consolidated financial statements.

Fair Value of Financial Instruments

6 Months Ended

Jun. 30, 2021

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

2. Fair Value of Financial Instruments

The Company follows accounting guidance for fair value measurements and disclosures, which establishes a fair value hierarchy that requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.  Fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three-tier fair value hierarchy has been established, which prioritizes the inputs used in measuring fair value as follows:

Level 1: inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2: inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities.

Level 3: unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Cash equivalents are measured at fair value and investments are recognized at amortized cost in the Company’s financial statements.  Accounts receivable is a financial asset with a carrying value that approximates fair value due to the short-term nature of these assets.  Accounts payable, accrued employee compensation and certain operating liabilities are financial liabilities with a carrying value that approximates fair value due to the short-term nature of these liabilities.

Business Combinations [Abstract]

Business Combination

4. Business Combinations

On April 30, 2021, the Company acquired all the outstanding stock of Smarteq Wireless Aktiebolag (“Smarteq”), a Swedish company based in Kista, Sweden that designs antennas for specialized industrial IoT and vehicular applications, pursuant to a Share Sale and Purchase Agreement (the “SPA”) between PCTEL and Allgon Aktiebolag, a Swedish company and holder of the outstanding stock of Smarteq. Smarteq owns all the outstanding stock of SAS Smarteq France (“Smarteq France”), which engages in sales of Smarteq products.

Pursuant to the SPA, the Company acquired Smarteq for a cash purchase price consisting of SEK 53.0 million plus working capital adjustments of SEK 1.6 million and an adjustment for the net cash at closing of SEK 2.1 million for total cash consideration of SEK 56.8 million ($6.8 million), all of which was provided from PCTEL’s existing cash. The Company believes the acquisition of Smarteq will provide a strong local presence, expertise, and channel partners to accelerate revenue growth in Europe, as well as a complementary portfolio of products for our Industrial IoT and intelligent transportation customers worldwide.  The results for Smarteq are combined with the Company’s antenna and Industrial IoT device product line.  The Company applied the provisions of Accounting Standards Codification (ASC) 805, Business Combinations, in accounting for its acquisitions. It requires the Company to recognize separately from goodwill the assets acquired, and the liabilities assumed, at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the acquisition date fair values of the net assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions where applicable to accurately value assets acquired and liabilities assumed at the acquisition date its estimates are inherently uncertain and subject to refinement. The purchase price allocation is preliminary because the evaluations necessary to assess the fair values of the net assets acquired are still in process.  As a result, during the measurement period, which may be up to one year from the acquisition date, the Company will record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments will be recorded to the consolidated statements of operations.  The operating results of the acquired business are included in the Company’s Consolidated Financial Statements from the date of the acquisition.

Fair Value of Purchase Consideration:

The following table summarizes the fair value of purchase consideration to acquire Smarteq:

Fair value of purchase consideration
Cash	$	6,785
Working capital adjustment		(5	)

Preliminary Purchase Price Allocation:

The Company acquired all of the assets and liabilities of Smarteq, including cash of $0.5 million and debt of $0.1 million.

The following is an allocation of the purchase price as of the April 30, 2021 closing date based upon a preliminary estimate of the fair value of the assets acquired and liabilities assumed by the Company in the acquisition:

Assumptions in the Allocations of Purchase Price

The Company prepared the purchase price allocation and in doing so utilized reports of a third-party valuation expert to calculate the fair value of the identifiable intangible assets.  Estimates of fair value require management to make significant estimates and assumptions which are preliminary and subject to change upon finalization of the valuation analysis. The goodwill recognized is attributable primarily to the acquired workforce, expected synergies, and other benefits that the Company believes will result from integrating the Smarteq operations with the operations of the Company. Updates to and/or completion of the valuations of certain assets acquired and liabilities assumed may result in changes to the recorded amounts of assets and liabilities, with corresponding adjustments to goodwill amounts in subsequent periods. The Company expects to complete the purchase price allocation within 12 months of the respective acquisition date.  The areas that are not yet finalized relate to intangible assets, goodwill and inventory.

The fair value of the customer relationships was determined using the multi-period excess earnings method (“MPEEM”). MPEEM estimates the value of an intangible asset by quantifying the amount of residual (or excess) cash flows generated by the future

customer cash flows, and discounting those cash flows to the present value. Future cash flows for customers were estimated based on forecasted revenue and costs, taking into account the growth rates, customer attrition, and contributory charges. The fair value of the customer backlog was calculated using the present value of the cash flows associated with the acquired backlog.

The fair values of the trade names, developed technology, and exclusive rights were determined using the relief-from-royalty method. The relief-from-royalty method is a specific application of the discounted-cash-flow method, which is a form of the income approach. It is based on the principle that ownership of the intangible asset relieves the owner of the need to pay a royalty to another party in exchange for rights to use the asset. Key assumptions to estimate the hypothetical royalty rate include observable royalty rates, which are royalty rates in negotiated licenses and market-based royalty rates which are royalty rates found in available market data for licenses involving similar assets.

The fair value of covenants to non-compete was estimated using the with-or-without method. The with-and-without method estimates the value of an intangible asset by quantifying the loss of economic profits under a hypothetical condition where only the subject intangible does not exist and needs to be re-created. Projected revenues, operating expenses and cash flows are calculated in each "with" and "without" scenario and the difference in the cash flow is discounted to present value.

Inventory was valued at net realizable value.  Raw materials were valued at book value and finished goods were valued assuming hypothetical revenues from finished goods adjusted for disposal costs, profit attributable to the seller and holding costs. An inventory step-up of $0.5 million is included in the purchase price allocation above.  Approximately $0.3 million of the inventory step-up was recognized during the three months ended June 30, 2021.  

The Company assumed gross accounts receivable of $1.4 million.  Based on Smarteq’s bad debt experience and a review of the receivables, the Company does not anticipate an issue with collectability.  

The Company assumed liabilities in the acquisition which primarily consist of accounts payable, accrued employee compensation and certain operating liabilities. The fair value of the liabilities assumed are valued at their cash settlement value.

As part of the acquisition of Smarteq on April 30, 2021, the Company assumed an office lease. The office in Kista, Sweden has 4,080 square feet used for engineering, sales, and administration and the lease term is through July 31, 2023.  On the acquisition date, the Company recorded $0.2 million for each of the right-of-use assets and the lease liabilities.

The Company assumed Smarteq France’s five-year loan of approximately $0.1 million with an interest rate of 0.57%.  The loan was part of a program from the French Ministry of Economy and Finance to support for French businesses during the COVID-19 pandemic.  The loan is denominated in Euros.  Payment of the interest and principal on the loan are deferred until June 2022 and the loan term ends in May 2026.  

The Company recorded net deferred tax assets of $2.4 million, primarily relating to deferred tax assets for net operating losses. The Company also booked a deferred tax asset for inventory reserves and deferred tax liabilities related to intangible asset amortization that is not deductible for income taxes.  The Company booked a full valuation allowance against the net deferred tax assets.  While the Company expects book and tax profits in 2021 and future periods, Smarteq has recorded a three-year cumulative tax loss.  Based on this objective evidence and uncertainty associated with the COVID-19 pandemic, the Company recorded a full valuation allowance on the opening balance sheet.

Goodwill recorded in connection with the acquisition was $3.3 million. The Company does not expect to deduct any of the acquired goodwill for tax purposes. The Company recorded $0.3 million of transaction costs in general and administrative expenses in the statement of operations.  The transaction costs will not be deductible for income tax purposes.

Cash and Cash Equivalents

At June 30, 2021 and December 31, 2020, cash and cash equivalents included bank balances and investments with original maturities of less than 90 days.  At June 30, 2021 and December 31, 2020, the Company’s cash equivalents were invested in highly liquid AAA rated money market funds that are required to comply with Rule 2a-7 of the Investment Company Act of 1940.  Such funds utilize the amortized cost method of accounting, seek to maintain a constant $1.00 per share price, and are redeemable upon demand.  The Company restricts its investments in AAA money market funds to those invested 100% in either short-term U.S. government agency securities or bank repurchase agreements collateralized by these same securities.  The fair values of these money market funds are established through quoted prices in active markets for identical assets (Level 1 inputs).  The Company’s cash in U.S. banks is insured by the Federal Deposit Insurance Corporation up to the insurable limit of $250.

The Company had cash in foreign bank accounts of $3.2 million at June 30, 2021 and $2.9 million at December 31, 2020.  The Company had $2.3 million and $2.9 million of cash and cash equivalents in bank accounts in China at June 30, 2021 and December 31, 2020, respectively, and the Company had $0.9 million of cash in its Sweden and France bank accounts at June 30, 2021. The Company’s cash in its foreign bank accounts is not insured.  At June 30, 2021, $1.1 million of the cash and cash equivalents in China was invested in a 90-day deposit account classified as cash equivalents and $1.2 million was in cash accounts. As of June 30, 2021, the Company has no intention of repatriating the cash in its foreign bank accounts.  If the Company decides to repatriate the cash in the foreign bank accounts, it may have trouble doing so in a timely manner.  The Company may also be exposed to foreign currency fluctuations and taxes if it repatriates these funds.   

Investments

At June 30, 2021 and December 31, 2020, the Company’s investments consisted of corporate bonds with ratings at the purchase date of A or higher and certificates of deposit. All the investments at June 30, 2021 and December 31, 2020 were classified as held-to-maturity.  The bonds and certificates of deposit classified as short-term investments have original maturities greater than 90 days and mature within one year and the bonds and certificates of deposit classified as long-term investments have maturities greater than one year but less than two years.  The Company’s bond investments are recorded at the purchase price and carried at amortized cost.  

Effective January 1, 2020, the Company adopted ASU 2016-13.  This ASU replaces the incurred loss impairment model with an expected loss impairment model for financial instruments, including short-term investments.  The amendment requires entities to consider forward-looking information to estimate expected credit losses.  Under ASU 2016-13, the Company classifies its held-to-maturity investment portfolio by the investment type and further classifies the corporate bonds by the bond ratings.  For estimating potential credit losses, the Company considers the historical loss data, the bond ratings, as well as and current and future economic conditions.

Cash equivalents and investments were as follows at June 30, 2021 and December 31, 2020:

Goodwill and Intangible Assets

6. Goodwill and Intangible Assets

Goodwill    

The change in the carrying amount of goodwill during the six months ended June 30, 2021 is as follows:

	Amount
Balance at December 31, 2020	$	3,332
Acquisition of Smarteq		3,259
Foreign currency translation		(69	)
Balance at June 30, 2021	$	6,522

The Company performs an annual impairment test of goodwill as of the end of the first month of the fourth fiscal quarter (October 31), or at an interim date if an event occurs or if circumstances change that would indicate that an impairment loss may have been incurred. In performing the annual impairment test, the Company may consider qualitative factors that would indicate possible impairment. A quantitative fair value assessment is also performed at the reporting unit level. If the fair value exceeds the carrying value, then goodwill is not impaired, and no further testing is performed. If the carrying value exceeds the fair value, the implied fair value of goodwill is then compared against the carrying value of goodwill to determine the amount of impairment.  In addition to the annual impairment test, the Company is required to regularly assess whether a triggering event has occurred which would require interim impairment testing. The Company considered the current and expected future economic and market conditions surrounding the COVID-19 pandemic and its impact on each of the reporting units. Further, the Company assessed the current market capitalization, and financial forecasts.  There were no triggering events during the six months ended June 30, 2021 and June 30, 2020.  The Company will continue to monitor goodwill for impairment going forward.

Balance Sheet Information

7. Balance Sheet Information

Accounts Receivable

Accounts receivable are recorded at invoiced amounts with standard net terms that range between 30 and 90 days.  The Company extends credit to its customers based on an evaluation of a customer’s financial condition and collateral is generally not required.  The Company records reserves for credit losses and credit allowances that reduce the value of accounts receivable to fair value.

The allowances for accounts receivable consisted of the following:

	June 30, 2021		December 31, 2020
Credit loss provision	$	32	$	66
Credit allowances		48		47
Total allowances	$	80	$	113

Effective January 1, 2020, the Company adopted ASU 2016-13.  This ASU replaces the incurred loss impairment model with an expected loss impairment model for financial instruments, including accounts receivable.  The amendment requires entities to consider forward-looking information to estimate expected credit losses.  The Company did not record an adjustment upon adoption of ASU 2016-13.  

The Company is exposed to credit losses primarily through the sale of products. The Company’s expected loss methodology for accounts receivable is developed using historical collection experience, current and future economic market conditions, and a review of the current status of customers’ trade accounts receivable. Due to the short-term nature of accounts receivable, the estimate of amount of accounts receivable that may not be collected is based on aging of the account receivable balances and the financial condition of customers. Additionally, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. The Company’s monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of customers' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible. The Company’s allowance for credit losses was $0.03 million at June 30, 2021 and $0.07 million at December 31, 2020.  

The following table summarizes the allowance for credit losses activity during the six months ended June 30, 2021:

Balance at December 31, 2020	$	66
Current period benefit for credit losses		(34	)
Balance at June 30, 2021	$	32

Inventories

Inventories are stated at the lower of cost or net realizable value and include material, labor and overhead costs using the first-in, first-out method of costing.  Inventories as of June 30, 2021 and December 31, 2020 were composed of raw materials, work-in-process and finished goods.  The Company had consigned inventory with customers of $0.5 million and $0.3 million at June 30, 2021 and December 31, 2020, respectively.  The Company records allowances to reduce the value of inventory to the lower of cost or net realizable value, including allowances for excess and obsolete inventory.  Reserves for excess inventory are calculated based on an estimate of inventory in excess of normal and planned usage.  Obsolete reserves are based on the identification of inventory where the carrying value is above net realizable value.  The allowance for inventory losses was $3.8  million at June 30, 2021 and $3.7 million at December 31, 2020.

Inventories, net consisted of the following:

	June 30, 2021		December 31, 2020
Raw materials	$	5,646	$	5,315
Work-in-process		975		883
Finished goods		5,770		3,786
Inventories, net	$	12,391	$	9,984

Prepaid Expenses and Other Assets

Prepaid assets are stated at cost and are amortized over the useful lives (up to one year) of the assets.

Property and Equipment

Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the assets.  The Company depreciates computer equipment and software licenses over three to five years, office equipment, manufacturing and test equipment, and motor vehicles over five years, furniture and fixtures over seven years, and buildings over 30 years.  Leasehold improvements are amortized over the shorter of the corresponding lease term or useful life.  Depreciation expense and gains and losses on the disposal of property and equipment are included in cost of sales and operating expenses in the condensed consolidated statements of operations.  Maintenance and repairs are expensed as incurred.

Property and equipment consisted of the following:

Service-Based Awards

Restricted Stock

The Company grants service-based stock awards to employees under its long-term incentive plan (“LTIP”).  All stock awards to employees are issued under the PCTEL, Inc. 2019 Stock Incentive Plan.  For the annual awards granted to executives and key

managers in the six months ended June 30, 2021 and 2020, respectively, the awards were comprised one-third of service-based restricted awards and two-thirds of performance-based awards. When service-based restricted stock is granted, the Company records deferred stock compensation within additional paid-in capital, representing the fair value of the common stock on the date the restricted shares are granted.  The Company records stock compensation expense on a straight-line basis over the vesting period of the applicable service-based restricted shares.  

The following table summarizes service-based restricted stock activity for the six months ended June 30, 2021: 

	Shares			Weighted Average Fair Value
Unvested Restricted Stock Awards - December 31, 2020		432,422		$	6.90
Shares awarded		170,158			8.04
Shares vested		(270,607	)		6.60

Restricted Stock Units

The Company grants service-based restricted stock units as employee incentives.  Restricted stock units are primarily granted to foreign employees for long-term incentive purposes.  Employee restricted stock units are service-based awards and are amortized over the vesting period.  At the vesting date, these units are converted to shares of common stock.  The Company records expense on a straight-line basis for restricted stock units.

The following table summarizes the restricted stock unit activity during the six months ended June 30, 2021:

	Shares			Weighted Average Fair Value
Unvested Restricted Stock Units - December 31, 2020		9,083		$	7.02
Units awarded		17,800			7.11
Units vested/Shares awarded		(5,446	)		6.47
Unvested Restricted Stock Units - June 30, 2021		21,437		$	7.23

The intrinsic value of service-based restricted stock units that vested and were issued as shares during the six months ended June 30, 2021 and 2020 was $42 and $44, respectively. In June 2021, the Company issued 15,000 service-based restricted stock units to employees of the Swedish subsidiary, Smarteq, with a four-year vesting period commencing in 2022.   

Stock Options

The Company may grant employees stock options to purchase common stock.  The Company issues stock options with exercise prices no less than the fair value of the Company’s stock on the grant date.  Employee stock options are subject to installment vesting typically over a period of not less than three years.  Stock options may be exercised at any time prior to their expiration date or within 180 days of termination of employment, or such shorter time as may be provided in the related stock option agreement. The stock options outstanding at June 30, 2021 have a seven-year life.  

The following tables summarizes the stock option activity for the six months ended June 30, 2021:

	Options Outstanding			Weighted Average Exercise Price
Outstanding at December 31, 2020		16,250		$	6.54
Options exercised		(6,000	)		5.48
Options cancelled/expired		(6,250	)		7.89
Outstanding at June 30, 2021		4,000		$	6.02
Exercisable at June 30, 2021		3,664		$	5.93

During the six months ended June 30, 2021, the Company received proceeds of $8 and issued 1,420 shares for the exercise of 6,000 options. The intrinsic value of the options exercised was $53.  During the six months ended June 30, 2020, the Company received proceeds of $0.1 million from the exercise of options for 9,412 shares and issued 10,194 shares for the exercise of 52,355 options. The intrinsic value of the options exercised was $0.1 million. The Company did not grant stock options during the six months ended June 30, 2021 or 2020.

The following table summarizes information about stock options outstanding under all stock option plans:

	Options Outstanding					Options Exercisable
Range of Exercise Prices	Number Outstanding		Weighted Average Contractual Life (Years)	Weighted- Average Exercise Price		Number Exercisable		Weighted Average Exercise Price
$ 5.06 - $ 6.98		4,000	2.92	$	6.02		3,664	$	5.93

The weighted average contractual life and intrinsic value of options outstanding and options exercisable at June 30, 2021, was the following:

	Weighted Average Contractual Life (years)		Intrinsic Value
Options Outstanding		2.92	$	3
Options Exercisable		2.86	$	3

The intrinsic value is based on the share price of $6.55 at June 30, 2021.

For outstanding stock options, the Company calculated the fair value of each option grant on the date of grant using the Black-Scholes option-pricing model. Because the Company’s employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, the existing models may not necessarily provide a reliable single measure of the fair value of the employee stock options. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility and expected option life.  

The dividend yield rate is calculated by dividing the Company’s annual dividend by the closing price on the grant date. The risk-free interest rate is based on the U.S. Treasury yields with a remaining term that approximates the expected life of the options granted.  The expected volatility is based on a five-year historical period of the Company’s stock price. The expected life for options granted is based on historical data of employee exercise performance.  The Company records expense based on the graded vesting method.  

Performance-Based Equity Awards

Short-Term Incentive Plan

Incentive compensation earned by executives and key managers under the Company’s 2021 Short-Term Incentive Plan (“STIP”) will be settled 50% in cash and 50% in shares of the Company’s stock as was the case with the 2020 STIP.  Under both the 2021 STIP and 2020 STIP, payouts could be earned based on annual revenue and adjusted EBITDA targets.  No shares were earned under the 2020 STIP because the Company did not exceed the revenue or EBITDA thresholds.  

Long-Term Incentive Plan

The Company grants performance-based awards to executives and key managers to encourage sustainable growth, consistent earnings, and management retention.  Based on the fair value of the shares on the grant date, the Company records stock compensation expense over the performance period based on the estimated achievement of the award.

The following table summarizes the performance award activity:

	Awards at Target		Weighted Average Fair Value
Unvested Performance Awards - December 31, 2020		316,726	$	6.84
Awards granted		187,864		8.15
Unvested Performance Awards - June 30, 2021		504,590	$	7.33

The Company granted performance awards under its long-term incentive plan to executives and key managers in February 2021 (“2021 LTIP”).  The performance period for the 2021 LTIP is from January 1, 2021 through December 31, 2023.  At target, the total fair market value of the award was $1.5 million based on the average share price of $8.15 on the grant date.  On the award date, the aggregate number of shares that could be earned at target was 187,864 and the maximum number of aggregate shares that could be earned was 328,762.  

Under the 2021 LTIP and similar plans from 2019 and 2020, shares of the Company’s stock can be earned based on achievement of a three-year revenue growth target with a penalty if a certain adjusted EBITDA level is not maintained.  If the Company achieves less than the target growth over the performance period, the participant will receive fewer shares than the target award, determined on a straight-line basis. If the Company achieves greater than the target growth, the participant will receive more shares than the target award on an accelerated basis. Participants are required to be in service at the determination date of the award following the end of the performance period in order to receive the award. Shares earned will be fully vested shares.  The Company records stock compensation expense over the performance period based on the Company’s estimate of the aggregate number of shares that will be earned under the incentive plan.     

The following table summarizes the active performance-based long-term incentive plans at June 30, 2021:

			Number of Shares
	Share Price		That Could Be Earned:
LTIP award	on Grant Date		Target		Maximum		Performance Period
2019 LTIP	$	5.27		171,437		295,325	January 1, 2019 through December 31, 2021
2020 LTIP	$	8.70		145,289		254,256	January 1, 2020 through December 31, 2022
2021 LTIP	$	8.15		187,864		328,762	January 1, 2021 through December 31, 2023
				504,590		878,343

Employee Stock Purchase Plan (“ESPP”)

The ESPP enables eligible employees to purchase common stock at the lower of 85% of the fair market value of the common stock on the first or last day of each offering period.  Each offering period is approximately six months.     

Based on the 15% discount and the fair value of the option feature of the ESPP, it is considered compensatory.  Compensation expense is calculated using the fair value of the employees’ purchase rights under the Black-Scholes model.

The Company calculated the fair value of each employee stock purchase grant on the date of grant using the Black-Scholes option-pricing model using the following assumptions:

	Employee Stock Purchase Plan
	2021			2020
Dividend yield		3.1	%		4.1	%
Risk-free interest rate		0.1	%		0.1	%
Expected volatility		48	%		44	%
Expected life (in years)		0.5			0.5

The dividend yield rate was calculated by dividing the Company’s annual dividend by the closing price on the grant date.  The risk-free interest rate was based on the U.S. Treasury yields with a remaining term that approximates the expected life of the options granted.  The volatility was based on a five-year historical period of the Company’s stock price.  The expected life was based on the offering period.

Board of Director Equity Awards

The Company grants equity awards to members of its Board of Directors as an annual retainer and for committee service. These awards are shares of the Company’s stock that vest upon issuance or, in some cases, one year after issuance. In addition, new directors receive a one-time grant that vests over three years. In May 2021, the Company issued 61,186 shares to directors for their annual retainer and committee services of which 49,652 shares vested immediately upon issuance, with the remainder vesting one year after issuance. The fair value of the service based restricted shares for directors that vested during the six months ended June 30, 2021 was $0.3 million.

The following table summarizes the director awards activity:

	Shares			Weighted Average Fair Value
Outstanding - December 31, 2020		2,416		$	6.90
Shares awarded		61,186			6.57
Shares vested		(52,068	)		6.65
Outstanding - June 30, 2021		11,534		$	6.57

 Employee Withholding Taxes on Stock Awards

For ease in administering the issuance of stock awards, the Company holds back shares of vested restricted stock awards, stock option exercises and short-term and long-term incentive plan stock awards for the value of the statutory withholding taxes.  For everyone receiving a share award, the Company redeems the shares it computes as the value for the withholding tax and remits this amount to the appropriate tax authority.  For withholding taxes related to stock awards, the Company paid $0.8 million and $1.1 million during the six months ended June 30, 2021 and 2020, respectively.

Stock Repurchases

On November 6, 2019, the Board of Directors approved a share repurchase program (“2019 Repurchase Plan”), which was reauthorized on March 10, 2020 under the 2019 Repurchase Plan, the Company was authorized to repurchase up to $7.0 million of its common stock through the end of 2020.  The Company spent $2.0 million to repurchase 375,046 shares at an average price of $5.36 during the three months ended March 31, 2020.  Due to uncertainties related to the COVID-19 pandemic and to protect the Company’s cash position, on April 1, 2020 the Board of Directors approved the termination of the 2019 Repurchase Plan.  

On November 4, 2020, the Board of Directors approved a $5.0 million share repurchase program (“2020 Repurchase Plan”). The Company spent $1.8 million to repurchase 288,573 shares at an average price of $6.30 during the three months ended December 31, 2020 and the Company spent $0.7 million during the six months ended June 30, 2021 to repurchase 112,951 shares at an average price of $6.49.  The Company retired all repurchased shares.

Authorized Shares

On May 29, 2020, the Company filed a Certificate of Amendment to its Amended and Restated Certificate of Incorporation (i) changing the Company’s name from “PC-Tel, Inc.” to “PCTEL, Inc.” and (ii) decreasing the number of authorized shares of common stock from 100,000,000 shares to 50,000,000 shares.

China Restructuring

On August 7, 2019, the Company’s Board of Directors approved a transition plan for the Company’s China manufacturing operations. As part of the plan, the Company is transitioning high-volume manufacturing from its Tianjin, China facility to contract manufacturers in China and elsewhere in order to reduce fixed costs in China, optimize the cost structure of the antenna product line, and create flexibility in antenna manufacturing due to the uncertainty of the lease of the current manufacturing premises, as described below. For the year ended December 31, 2020, the Company incurred restructuring expenses of $0.1 million for employee severance related to the separation of 12 employees and for the year ended December 31, 2019, the Company incurred restructuring expenses of $0.5 million for employee severance and related benefits related to the separation of 84 employees.   Severance costs were paid from the Company’s cash in its China bank accounts.      

On October 8, 2020, the lease of the premises on which the Company’s China manufacturing operations are conducted expired and the renewal is pending and uncertain. The Company has been notified that the Chinese Party Central Committee and the State Council are accelerating the layout optimization and transformation of the industrial park in which the Company’s leased premises is located and, accordingly, leases and lease extensions for all premises in the industrial park have been suspended and rent collection has been postponed.  The Company has not received an indication of the likelihood of approval of its lease extension.  However, should the lease ultimately be extended, rent will be due for the period of the lease suspension.  As a result of the uncertainty regarding the Tianjin Lease (as defined in Note 11) renewal, the Company is refining its transition plan for the manufacturing activities conducted on the leased premises. As part of the refined transition plan, the Company will retain a group of employees in Tianjin, China, but will reduce additional headcount in Tianjin and incur additional restructuring charges..  The Company expects the transition to be substantially completed by the end of the 2021 fiscal year.

The following table summarizes the restructuring activity during the six months ended June 30, 2021 and the status of the reserves at June 30, 2021:

Leases [Abstract]

Leases

11. Leases

The Company has operating leases for facilities and finance leases for office equipment.  Leases with an initial term of 12 months or less are not recorded in the balance sheet.  The Company determines if an arrangement is a lease at inception of a contract.

Right of Use (“ROU”) assets represent the Company's right to use an underlying asset during the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the net present value of fixed lease payments over the lease term. The Company's lease term is deemed to include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. ROU assets also include any advance lease payments made and exclude lease incentives. As most of the Company's operating leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments on a collateralized basis. Finance lease agreements generally include an interest rate that is used to determine the present value of future lease payments. Operating fixed lease expense and finance lease depreciation expense are recognized on a straight-line basis over the lease term.

The Company's lease cost for the three and six months ended June 30, 2021 and 2020, respectively, included the following components:

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020

 On March 5, 2020, PCTEL (Tianjin) Wireless Telecommunications Products, Co. Ltd., a wholly owned subsidiary of the Company (“PCTEL Tianjin”), entered into a letter agreement with Wang Zhuang Village Committee of Tianjin, China (the “Letter Agreement”) specifying the terms for extension of the lease of the premises on which PCTEL Tianjin currently conducts its manufacturing activities in Tianjin, China (the “Tianjin Lease”) to October 2022. The Letter Agreement did not, however, effect the lease extension. The Tianjin Lease expired on October 8, 2020 without extension.  On October 16, 2020, the Wang Zhuang Village Committee issued a notice informing PCTEL Tianjin that the Chinese Party Central Committee and the State Council are accelerating the layout optimization and transformation of the industrial park in which the leased premises is located, and accordingly leases and lease extensions for all premises in the industrial park have been suspended and rent collection has been postponed. The letter indicates that if the Tianjin Lease extension is subsequently approved, the rent for the period from October 9, 2020 to the date of the Tianjin Lease extension (the “Intervening Period”) will then be due and payable.  In July 2021, PCTEL Tianjin received an indication from local Chinese authorities that the Tianjin lease extension is likely to be approved for a period of October 10, 2020 to December 31, 2021 and lease negotiations have commenced. However, based upon past practices and verbal assurances, the Company believes that PCTEL Tianjin will have not less than 30 days to vacate the leased premises if the Lease Extension is not approved.    

As part of the acquisition of Smarteq on April 30, 2021, the Company assumed an office lease and an automotive lease. The office in Kista, Sweden has 4,080 square feet used for engineering, sales, and administration with a lease term ending July 31, 2023.  On the acquisition date, the Company recorded $0.2 million for each of the right-of-use assets and the lease liabilities.

Income Tax Disclosure [Abstract]

Income Taxes

13. Income Taxes

The Company recorded income tax expense of $12 and $16 for the six months ended June 30, 2021 and 2020, respectively. The expense recorded for the six months ended June 30, 2021 and 2020 was lower than the statutory rate of 21% because the Company has a full valuation allowance on its deferred tax assets. The Company’s valuation allowance is due to the uncertainty regarding the utilization of the deferred tax assets.

The Company had deferred tax assets net of deferred tax liabilities of $15.2 million at June 30, 2021 and $12.9 million at December 31, 2020. The deferred tax assets consisted of domestic deferred tax assets of $12.1 million, China deferred tax assets of $0.8 million, and $2.3 million of deferred tax assets for Sweden. The Company’s gross deferred tax assets consist of federal and state net operating losses (“NOLs”), credits, and timing differences. As part of the acquisition of Smarteq, the recorded deferred tax assets of $2.3 million associated with net operating losses inventory reserves and recorded tax liabilities associated with acquired intangible assets.  Because of the objective evidence of cumulative three-year losses and uncertainty associated with the COVID-19 pandemic, the Company recorded a full valuation allowance on the deferred tax assets.  

The Company’s federal NOLs generated in 2018 and future periods will not expire, and the Company’s NOLs and credits generated as of December 31, 2017 have a finite life primarily based on the 20-year carry forward of federal net operating losses. The timing differences have a ratable reversal pattern over 12 years. On a regular basis, the Company evaluates the recoverability of deferred tax assets and the need for a valuation allowance. Such evaluations involve the application of significant judgment. The Company considers multiple factors in its evaluation of the need for a valuation allowance. The Company generated book and tax income during 2020 but generated book losses for the six months ended June 30, 2021. The Company believes its financial outlook remains positive but because of difficulties with forecasting financial results historically, and due to the uncertainties associated with the COVID-19 pandemic, the Company maintained a full valuation allowance on its deferred tax assets at June 30, 2021 and December 31, 2020.  

The analysis that the Company prepared to determine the valuation allowance required significant judgment and assumptions regarding future market conditions as well as forecasts for profits, taxable income, and taxable income by jurisdiction. Due to the sensitivity of the analysis, changes to the assumptions in subsequent periods could have a material effect on the valuation allowance.

The Company files a consolidated federal income tax return, income tax returns with various states, and foreign income tax returns in various foreign jurisdictions. The Company’s U.S. federal tax returns remain subject to examination for 2017 and subsequent periods. The Company’s U.S. state tax returns remain subject to examination for 2015 and subsequent periods. The Company’s foreign tax returns remain subject to examination for 2011 and subsequent periods. The Company’s gross unrecognized tax benefit was $0.8 million at June 30, 2021 and December 31, 2020.

On March 27, 2020, the “Coronavirus Aid, Relief and Economic Security Act” (CARES Act) was signed into law. The CARES Act includes provisions relating to refundable payroll tax credits, deferment of the employer portion of certain payroll taxes, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property.  Under the CARES Act, the Company is deferring the employer portion of social security taxes and will apply for a refund of its Alternative Minimum Tax credit.  As of June 30, 2021, the Company has deferred $0.5 million of payroll taxes. The payroll taxes will be deferred until the due dates of December 31, 2021 and December 31, 2022.  The Company records a deferred tax asset for the payroll tax liability due by December 31, 2022 that is not deductible in 2021 for income tax purposes.

Revenue From Contract With Customer [Abstract]

Revenue from Contracts with Customers

15. Revenue from Contracts with Customers

Under Topic 606, a contract with a customer is an agreement which both parties have approved, that creates enforceable rights and obligations, has commercial substance, and specified payment terms, and for which collectability is probable. Once the Company has entered into a contract, it is evaluated to identify performance obligations. For each performance obligation, revenue is recognized as control of promised goods or services transfers to the customer in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services. The amount of revenue recognized takes into account variable consideration, such as returns and volume rebates.  A majority of the Company’s revenue is short cycle in nature with shipments within one year from order. The Company's payment terms generally range between 30 to 90 days.

All of the Company’s revenue relates to contracts with customers.  The Company’s accounting contracts are from purchase orders or purchase orders combined with purchase agreements.  The majority of the Company’s revenue is recognized on a “point-in-time” basis and a nominal amount of revenue is recognized “over time”.  For the sale of antenna products and test & measurement products, the Company satisfies its performance obligations generally at the time of shipment or upon delivery based on the contractual terms with its customers.  For products shipped on consignment, the Company recognizes revenue upon delivery from the consignment location.  For its test & measurement software tools, the Company has a performance obligation to provide software maintenance and support for one year.  The Company recognizes revenues for the maintenance and support over this period.  

The Company considers shipping and handling performed by the Company as fulfillment activities.  Amounts billed for shipping and handling are included in revenues, while costs incurred for shipping and handling are included in cost of revenues.  The Company excludes taxes from the transaction price.  Cost of contracts include sales commissions.  The Company expenses the cost of contracts when incurred because the amortization period is one year or less.

The Company allows its major distributors and certain other customers to return unused product under specified terms and conditions.  The Company estimates product returns based on historical sales and return trends and records a corresponding refund liability.  The refund liability was $0.2 million and $0.1 million at June 30, 2021 and December 31, 2020 respectively and is included within accrued liabilities in the accompanying condensed consolidated balance sheets.  The Company records an asset based on historical experience

for the amount of product it expects to return to inventory as a result of customer returns, which is recorded in inventories in the accompanying condensed consolidated balance sheets.  The product return asset was $0.1 million at June 30, 2021 and December 31, 2020.

There were no contract assets at June 30, 2021 or December 31, 2020. The Company records contract liabilities for deferred revenue and customer prepayments.  Contract liabilities are recorded in accrued liabilities in the accompanying condensed consolidated balance sheets.  The contract liability was $0.5 million and $0.4 million at June 30, 2021 and December 31, 2020, respectively.  The Company recognized revenue of $0.5 million and $0.4 million during the six months ended June 30, 2021 and 2020, respectively, related to contract liabilities that existed at the beginning of the period.

Foreign Operations

Foreign Operations

Cross-border transactions, both with external parties and in our internal operations, result in exposure to foreign exchange rate fluctuations. We are exposed to currency risk with the Chinese Yuan due to our operations in China, and with other foreign currencies related to the acquisition of Smarteq (see Note 4) and related to suppliers and employees outside the U.S. Fluctuations could have an adverse effect on our results of operations and cash flows. We manage certain operating activities at the local level with revenues,

costs, assets, and liabilities generally being denominated in local currencies. However, our results of operations and assets and liabilities are reported in U.S. dollars and thus will fluctuate with changes in exchange rates between such local currencies and the U.S. dollar.  Gains and losses resulting from transactions originally in foreign currencies and then translated into U.S. dollars are included in the condensed consolidated statements of operations.  For the six months ended June 30, 2021, approximately 6% of revenues and 18% of expenses were transacted in foreign currencies as compared to 3% and 18% for the six months ended June 30, 2020.  Net foreign exchange losses resulting from foreign currency transactions included in other income, net were $(53) and $(18) for the three months ended June 30, 2021 and 2020, respectively.  Net foreign exchange gains(losses) resulting from foreign currency transactions included in other income, net was $(45) and $19 for the six months ended June 30, 2021 and 2020, respectively.          

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”), Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (ASU 2017-14).  This guidance eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge.  Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value.  The changes are effective for smaller reporting companies for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, and early adoption is permitted.  The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (“Topic 848”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This update provides optional expedients and exceptions for applying generally accepted accounting principles to certain contract modifications and hedging relationships that reference London Inter-bank Offered Rate (LIBOR) or another reference rate expected to be discontinued. Topic 848 is effective upon issuance and generally can be applied through December 31, 2022.  The Company is currently evaluating the impact of Topic 848 on the consolidated financial statements.

Lease description		On March 5, 2020, PCTEL (Tianjin) Wireless Telecommunications Products, Co. Ltd., a wholly owned subsidiary of the Company (“PCTEL Tianjin”), entered into a letter agreement with Wang Zhuang Village Committee of Tianjin, China (the “Letter Agreement”) specifying the terms for extension of the lease of the premises on which PCTEL Tianjin currently conducts its manufacturing activities in Tianjin, China (the “Tianjin Lease”) to October 2022. The Letter Agreement did not, however, effect the lease extension. The Tianjin Lease expired on October 8, 2020 without extension.  On October 16, 2020, the Wang Zhuang Village Committee issued a notice informing PCTEL Tianjin that the Chinese Party Central Committee and the State Council are accelerating the layout optimization and transformation of the industrial park in which the leased premises is located, and accordingly leases and lease extensions for all premises in the industrial park have been suspended and rent collection has been postponed. The letter indicates that if the Tianjin Lease extension is subsequently approved, the rent for the period from October 9, 2020 to the date of the Tianjin Lease extension (the “Intervening Period”) will then be due and payable.  In July 2021, PCTEL Tianjin received an indication from local Chinese authorities that the Tianjin lease extension is likely to be approved for a period of October 10, 2020 to December 31, 2021 and lease negotiations have commenced. However, based upon past practices and verbal assurances, the Company believes that PCTEL Tianjin will have not less than 30 days to vacate the leased premises if the Lease Extension is not approved
