Discontinued Operations and Related Party Investment

(14) Discontinued Operations and Related Party Investment

In October 2020, the Company sold certain assets related to its Local Leads Platform, Call Marketplace and other assets not related to core conversational analytics. The purchaser is a related party controlled by a shareholder and officers of the Company. This divestiture represented a discontinued operation since the disposal enables the Company to focus more wholly on its core conversational analytics and sales engagement solution activities, and it will have a significant effect on the Company’s operations and financial results. The Company has no further involvement in the key strategic decision making or operations of the divested assets. Accordingly, we have presented the results of operations of these assets in the Condensed Consolidated Financial Statements as discontinued operations, net of tax, for historical periods.

The Company received cash consideration at closing of approximately $2.3 million. No gain or loss on the sale of discontinued operations was recognized in the Condensed Consolidated Statement of Operations as it was sold to a related party. The net consideration received from the sale is recognized in the Company’s Consolidated Statements of Stockholder’s Equity. The sale also includes (i) contingent consideration based on the achievement of certain revenue and thresholds from the Call Marketplace, Local Leads Platform and the purchaser’s total business; (ii) certain contingent sale transaction consideration; (iii) shares of Class B common stock in the purchaser equal to the issuance of a 10% equity interest; and (iv) the cancellation of Company stock options for 1.5 million shares currently held by two officers of the Company who are involved in the transaction.

In connection with the closing, the Company also entered into an administrative support services agreement with the related party purchaser pursuant to which the Company will provide services to the related party purchaser for a support services fee, with certain guaranteed payments to the Company in the first year and conditionally in the second year following closing. Support services fees related to this arrangement totaled $1.2 million for the three months ended March 31, 2021 and are included in the Company’s Condensed Consolidated Statements of Operations, net of the related expenses, within Service costs, Sales and marketing, Product development, and General and administrative.

As of March 31, 2021, the net amount of $242,000 is due from the purchaser and is included in the Company’s Condensed Consolidated Balance Sheet within Prepaid and other current assets as of March 31, 2021. The net amount due to the purchaser of $1.1 million is included in the Company’s Condensed Consolidated Balance Sheet within Accounts payable as of December 31, 2020.

The Company has determined that although we hold variable interests in the related party purchaser, we are not the primary beneficiary and are not required to consolidate the entity. We considered whether we have the ability to exercise significant influence over the operating and financial policies of the purchaser and do not believe these criteria were met. As a result, the Company has elected to measure the investment at cost because the equity securities do not have a readily determinable fair value. The investment

balance of $341,000 is included in Other assets, net on the Company’s Condensed Consolidated Balance Sheet as of December 31, 2020 and March 31, 2021.

The Condensed Consolidated Financial Statements for the three months ended March 31, 2020 reflect the operations of the divested assets as a discontinued operation. Discontinued operations include the following:

	Three months ended March 31, 2020
Revenue	$	12,778

Service costs		9,670

Commitments, Contingencies, and Taxes

(10) Commitments, Contingencies, and Taxes

Commitments

The Company has commitments for future payments primarily related to office facilities leases and other contractual obligations. The Company leases its office facilities under operating lease agreements in accordance with ASC 842 and recognizes rent expense on a straight-line basis over the lease term with any lease incentive amortized as a reduction of rent expense over the lease term. Other contractual obligations primarily relate to minimum contractual payments due to outside service providers. Future minimum payments are approximately as follows (in thousands):

	Facilities and other operating leases (1)		Other contractual obligations		Total
2021		1,441		819		2,260
2022		1,871		272		2,143

Total minimum payments	$	4,856	$	1,121	$	5,977
(1) For additional information regarding the Company's operating leases, see Note 9, Leases of the Notes to the Condensed Financial Statements.

Contingencies

The Company from time to time is a party to disputes and legal and administrative proceedings arising from the ordinary course of business. In some agreements to which the Company is a party, the Company has agreed to indemnification provisions of varying scope and terms with advertisers, vendors and other parties with respect to certain matters, including, but not limited to, losses arising out of the Company’s breach of agreements or representations and warranties made by the Company, services to be provided by the Company and intellectual property infringement claims made by third parties. As a result of these provisions, the Company may from

time to time provide certain levels of financial support to its contract parties to seek to minimize the impact of any associated litigation in which they may be involved. The Company has also entered into purchase arrangements that included earnout arrangements based on targeted financial goals that are subject to review and escrow provisions wherein a portion of consideration was placed into escrow in order to secure indemnification obligations. The escrow amounts are included as part of the purchase price consideration and if there is any excess escrow amount above identified indemnification obligations, the excess may be released. In the event any indemnification obligations are identified, the economic consideration may be reduced accordingly.

To date, there have been no known events or circumstances that have resulted in any material costs related to these indemnification provisions, additional earnout consideration, and no liabilities therefore have been recorded in the accompanying Condensed Consolidated Financial Statements. However, the maximum potential amount of the future payments we could be required to make under these provisions could be material.

While any litigation contains an element of uncertainty, the Company is not aware of any legal proceedings or claims which are pending that the Company believes, based on current knowledge, will have, individually or taken together, a material adverse effect on the Company’s financial condition, results of operations or liquidity.

Taxes

The Company determined that it is not more likely than not that its deferred tax assets will be realized and accordingly recorded 100% valuation allowance against these deferred tax assets as of December 31, 2020 (excluding certain insignificant Canadian deferred tax assets) and March 31, 2021. In assessing whether it is more likely than not that the Company’s deferred tax assets will be realized, factors considered included: historical taxable income, historical trends related to advertiser usage rates, projected revenues and expenses, macroeconomic conditions, issues facing the industry, existing contracts, the Company’s ability to project future results and any appreciation of its other assets. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the periods in which those temporary differences are deductible. The Company considered the future reversal of deferred tax liabilities, carryback potential, projected taxable income, and tax planning strategies as well as its history of taxable income or losses in the relevant jurisdictions in making this assessment. Based on the level of historical taxable losses and the uncertainty of projections for future taxable income over the periods for which the deferred tax assets are deductible, the Company concluded that it is not more likely than not that the gross deferred tax assets will be realized.

From time to time, various state, federal and other jurisdictional tax authorities undertake audits of the Company and its filings. In evaluating the exposure associated with various tax filing positions, the Company on occasion accrues charges for uncertain positions. Resolution of uncertain tax positions will impact the Company’s effective tax rate when settled. The Company does not have any significant interest or penalty accruals. The provision for income taxes includes the impact of contingency provisions and changes to contingencies that are considered appropriate. The Company files U.S. federal, certain U.S. states, and certain foreign tax returns. Generally, U.S. federal, U.S. state, and foreign tax returns filed for years after 2012 are within the statute of limitations and are under examination or may be subject to examination.

Earnings Per Share [Abstract]

Net Income (Loss) Per Share

(7) Net Income (Loss) Per Share

The Company computes net income (loss) per share of Class A and Class B common stock using the two-class method. Under the provisions of the two-class method, basic net income (loss) per share is computed by dividing net income (loss) applicable to common stockholders by the weighted average number of common shares outstanding during the year. Diluted net income (loss) per share is computed by dividing net income (loss) applicable to common stockholders by the weighted average number of common and dilutive common equivalent shares outstanding during the period. The computation of the diluted net income (loss) per share of Class B common stock assumes the conversion of Class A common stock to Class B common stock, while the diluted net income (loss) per share of Class A common stock does not assume the conversion of those shares.

In accordance with the two-class method, the undistributed earnings (losses) for each year are allocated based on the contractual participation rights of the Class A and Class B common shares and the restricted shares as if the earnings for the year had been distributed. Considering the terms of the Company’s charter which provides that, if and when dividends are declared on the Company’s common stock in accordance with Delaware General Corporation Law, equivalent dividends shall be paid with respect to the shares of Class A common stock and Class B common stock and that both classes of common stock have identical dividend rights and would share equally in the Company’s net assets in the event of liquidation, the Company has allocated undistributed earnings (losses) on a proportionate basis.

Instruments granted in unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are participating securities prior to vesting. As such, the Company’s restricted stock awards are considered participating securities for purposes of calculating earnings per share.

Segment Reporting and Geographic Information

(3) Segment Reporting and Geographic Information

Operating segments are revenue-producing components of the enterprise for which separate financial information is produced internally for the Company’s management. For the three months ended March 31, 2020 and 2021, the Company operated in a single segment comprised of its core analytics and solutions services. In October 2020, the Company sold certain assets related to its Local Leads Platform, Call Marketplace and other assets not related to core conversational analytics. As a result, the operating results related to these assets are shown as discontinued operations in the Condensed Consolidated Statements of Operations for all periods presented. See Note 14. Discontinued Operations and Related Party Investment for further discussion.

Long-lived assets by geographical region are based on the location of the legal entity that owns the assets. As of December 31, 2020 and March 31, 2021, no significant long-lived assets were held by entities outside of the United States.

Revenues from customers by geographical areas are tracked on the basis of the location of the customer. The majority of the Company’s revenue and accounts receivable are derived from domestic sales to customers.

Revenues by geographic region are as follows (in percentages):

	Three months ended March 31,

Description of Business and Basis of Presentation (Policies)	3 Months Ended
	Mar. 31, 2021
Accounting Policies [Abstract]
Description of Business	Description of Business Marchex, Inc. (the “Company”) was incorporated in the state of Delaware on January 17, 2003. The Company is a conversational analytics and solutions company that helps businesses connect, drive, measure, and convert callers into customers, and connects the voice of the customer to their business. We deliver data insights and incorporate artificial intelligence (AI)-powered functionality that drives insights and solutions to help companies find, engage and support their customers across voice and text-based communication channels. Divestiture In October 2020, the Company sold its interests in certain assets related to its Local Leads Platform, Call Marketplace and other assets not related to core conversational analytics and sales engagement solutions. The purchaser is a related party controlled by a shareholder and officers of the Company. The assets met the definition of a business and represented a discontinued operation since the disposal enabled the Company to focus more wholly on its core conversational analytics and sales engagement solution activities, and it had a significant effect on the Company’s operations and financial results. The Company will have no further involvement in the key strategic decision making or operations of the business. As a result, the operating results related to these assets are shown as discontinued operations, net of tax, in the Condensed Consolidated Statements of Operations for the three months ended March 31, 2020. See Note 14. Discontinued Operations and Related Party Investment of the Notes to the Condensed Consolidated Financial Statements for further discussion. Unless otherwise indicated, information presented in the Notes to the Financial Statements relates only to the Company’s continuing operations.
The Impact of COVID-19 on our Business	The Impact of COVID-19 on our Business In late 2019, an outbreak of COVID-19 emerged and by March 2020, was declared a global pandemic by the World Health Organization. Across the United States and the world, governments and municipalities instituted measures in an effort to control the spread of COVID-19, including quarantines, shelter-in-place orders, school closings, travel restrictions and the closure of non-essential businesses. By the end of March, the macroeconomic impacts became significant, exhibited by, among other things, a rise in unemployment and market volatility. For most of the quarter ended March 31, 2020, the Company’s results reflect historical trends and seasonality. However, beginning in March 2020, the Company experienced a decline in revenues due to the impact of COVID-19 and the related reductions in global economic activity and reduced spending by its customers in response to the macroeconomic impact. During the quarter ended March 31, 2020, the Company also assessed the realized and potential credit deterioration of its customers due to changes in the macroeconomic environment, which has been reflected in an increase in its allowance for credit losses for accounts receivable as of March 31, 2020 and December 31, 2020. Additionally, the Company determined that indicators of impairment had occurred during the first quarter of 2020, which resulted in the Company performing an interim impairment analysis during the first quarter of 2020. As a result of this interim impairment test, the Company recognized an impairment of its intangible long-lived assets and goodwill during the first quarter of 2020. See the Note 11. Identifiable Intangible Assets from Acquisitions and Note 12. Goodwill in these Notes to the Condensed Consolidated Financial Statements for additional information. For additional information for the effects of the COVID-19 pandemic and resulting global disruptions on the Company’s business and operations, refer to Item 2 of Part I, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Item 1.A of Part II, “Risk Factors”.
Basis of Presentation	Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading. The preparation of our unaudited Condensed Consolidated Financial Statements requires management to make estimates and assumptions that affect the amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. The Company has used estimates related to several financial statement amounts, including revenues, allowance for doubtful accounts, allowance for advertiser credits, useful lives for property and equipment and intangible assets, valuation of intangible assets, valuation of contingent consideration transferred as a result of business combinations, the fair value of the Company’s common stock and stock option awards, the impairment of goodwill and the valuation allowance for deferred tax assets. The inputs into our judgments and estimates consider the economic implications of COVID-19 on our critical and significant accounting estimates. Actual results could differ from those estimates. Operating results for the three months ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021, or for any other period. The interim financial information is unaudited, and reflects all normal adjustments that are, in our opinion, necessary to provide a fair statement of results for the interim periods presented. The balance sheet at December 31, 2020 has been derived from the audited Consolidated Financial Statements at that date. This report should be read in conjunction with the Consolidated Financial Statements in our 2020 Form 10-K where we include additional information about our policies and the methods and assumptions used in our estimates. Our Company consolidates all entities that we control by ownership of a majority voting interest. All inter-company transactions and balances have been eliminated in consolidation. Certain reclassifications have been made to the Condensed Consolidated Financial Statements in the prior periods to conform to the current period presentation. Assets, liabilities and operations of foreign subsidiaries are recorded based on the functional currency of the entity. For a majority of our foreign operations, the functional currency is the U.S. dollar. Assets and liabilities denominated in other than the functional currency are remeasured each month with the remeasurement gain or loss recorded in other income and expense in the Condensed Consolidated Statements of Operations.
Recent Accounting Pronouncement Not Yet Effective	Recent Accounting Pronouncements Not Yet Effective In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments — Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (ASU 2016-13), an ASU amending the impairment model for most financial assets and certain other instruments. Early adoption is permitted after December 15, 2018. The ASU must be adopted using a modified-retrospective approach. In November 2018, the FASB issued Accounting Standards Update No. 2018-19, Codification Improvements (Topic 326), Financial Instruments - Credit Losses (ASU 2018-19), an ASU intended to improve the Codification or correct its unintended application. The ASU is effective upon the adoption of the amendments in Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, with early adoption permitted after December 15, 2018. The Company does not expect adoption of ASU 2018-19 and ASU 2016-13 to have a material impact on its Condensed Consolidated Financial Statements. In addition, in May 2019, the FASB issued Accounting Standards Update No. 2019-05, Financial Instruments — Credit Losses (Topic 326), Targeted Transition Relief, (ASU 2019-05)), an ASU which provides ASU 2016-13 transition relief by providing entities with an alternative to irrevocably elect the fair value option for eligible financial assets measured at amortized cost upon adoption of the credit losses standard. To be eligible for the transition election, the existing financial asset must otherwise be both within the scope of the new credit losses standard and eligible for the applying the fair value option in ASC 825-10. The election must be applied on an instrument-by-instrument basis and is not available for either available-for-sale or held-to-maturity debt securities. The ASU is effective upon the adoption of the amendments in ASU 2016-13. In addition, in November 2019, the FASB issued Accounting Standards Update No. 2019-10, Financial Instruments - Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) - Effective Dates (ASU-2019-10), an ASU modifying the effective dates of various previous pronouncements. As the Company qualifies as a Smaller Reporting Company with the SEC, this ASU revised the effective date of ASU 2016-13 and ASU 2017-04 to fiscal years beginning after December 15, 2022. The Company does not expect adoption of ASU 2019-10 to have a material impact on our Consolidated Financial Statements. The Company does not expect adoption of ASU 2019-10, ASU 2019-05, ASU 2018-19 and ASU 2016-13 to have a material impact on its Consolidated Financial Statements. In February 2020, the FASB issued Accounting Standards Update No. 2020-02, Financial Instruments — Credit Losses (Topic 326) and Leases (Topic 842). This ASU adds an SEC paragraph pursuant to the issuance of SEC Staff Accounting Bulletin No. 119, which adds Topic 6M on Accounting for Loan Losses by Registrants Engaged in Lending Activities Subject to FASB ASC Topic 326. It also adds a note in paragraph 842-10-S65-1 regarding the updated effective date for Leases pursuant to the issuance of ASU 2019-10. Additionally, in March 2020 Accounting Standards Update No. 2020-03, Codification Improvements to Financial Instruments (ASU 2020-03), an ASU which represent changes to clarify or improve the Codification. The amendments make the Codification easier to understand and easier to apply by eliminating inconsistencies and providing clarifications. The amendments and are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. The Company does not expect adoption of ASU 2020-02 and of ASU 2020-03 to have a material impact on our Consolidated Financial Statements. In November 2019, the FASB issued Accounting Standards Update No. 2019-11, Codification Improvement to Topic 326, Financial Instruments — Credit Losses, an ASU which makes several amendments to the new credit losses standard, including an amendment requiring entities to include certain expected recoveries of the amortized cost basis previously written off, or expected to be written off, in the allowance for credit losses for purchased credit deteriorated assets. The amendments also provide transition relief related to troubled debt restructurings, allow entities to exclude accrued interest amounts from certain required disclosures and clarify the requirements for applying the collateral maintenance practical expedient. For entities that have not yet adopted the new credit losses standard, the effective dates and transition requirements are the same as those in ASU 2016-13. For entities that have adopted the new credit losses standard, the amendments are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted in any interim period, as long as the entity has adopted the new credit losses standard. The ASU must be adopted using a modified-retrospective approach. The Company does not expect adoption of ASU 2019-11 to have a material impact on its Consolidated Financial Statements. In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes, an ASU which eliminates certain exceptions to the guidance in Accounting Standards Codification (ASC or Codification) 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new guidance also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The guidance also clarifies that single-member limited liability companies and similar disregarded entities that are not subject to income tax are not required to recognize an allocation of consolidated income tax expense in their separate financial statements, but they could elect to do so. The ASU is effective for reporting periods beginning after December 15, 2020, with early adoption permitted. The transition method related to the ASU amendments depend upon the nature of the guidance and vary depending upon the specific amendment being implemented. The Company does not expect adoption of ASU 2019-12 to have a material impact on its Consolidated Financial Statements.
Revenue Recognition	Revenue Recognition We generate the majority of our revenues from core analytics and solutions services. Customers typically receive the benefit of the Company’s services as they are performed and substantially all the Company’s revenue is recognized over time as the services are performed. Revenue is recognized when a customer obtains control of services in an amount that reflects the consideration the Company expects to receive in exchange for those services. The Company measures revenue based on the consideration specified in the customer arrangement, and revenue is recognized when the performance obligations in the customer arrangement are satisfied. A performance obligation is a promise in a contract to transfer a distinct service or product to the customer. The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when or as the customer receives the benefit of the performance obligation. The Company’s call analytics technology platform provides data and insights that can measure the performance of mobile, online and offline advertising for customers and small business resellers. The Company generates revenue from the Company’s call analytics technology platform when advertisers pay the Company a fee for each call/text or call/text related data element they receive from calls or texts or for each phone number tracked based on a pre-negotiated rate. Revenue is recognized as services are provided over time, which is generally measured by the delivery of each call/text or call/text related data element or each phone number tracked. The majority of the Company’s customers are invoiced on a monthly basis following the month of the delivery of services and are required to make payments under standard credit terms. Collection on the related receivables may vary from reported information based upon third-party refinement of the estimated and reported amounts owed that occurs subsequent to period ends. The Company establishes an allowance for advertiser credits, which is included in Other accrued expenses and current liabilities in the balance sheet, using its best estimate of the amount of expected future reductions in advertisers’ payment obligations related to delivered services based on analysis of historical credits. The balance associated with the allowance for advertiser credits in the Company’s Condensed Consolidated Balance Sheet was $206,000 and $216,000 as of December 31, 2020 and March 31, 2021, respectively. Customer payments received in advance of revenue recognition are also contract liabilities and are recorded as deferred revenue. The deferred revenue balance in the Company’s Condensed Consolidated Balance Sheet as of December 31, 2020 and March 31, 2021 was $1.4 million and $1.3 million, respectively. During the three months ended March 31, 2020 and 2021, revenue recognized that was included in the contract liabilities balances at the beginning of the period was $503,000 and $749,000, respectively. The majority of the Company’s total revenue is derived from contracts that include consideration that is variable in nature. The variable elements of these contracts primarily include the number of transactions (for example, the number qualified phone calls). For contracts with an effective term greater than one year, the Company applies the standard’s practical expedient that permits the exclusion of disclosure of the value of unsatisfied performance obligations for these contracts as the Company’s right to consideration corresponds directly to the value provided to the customer for services completed to date and all future variable consideration is allocated to wholly unsatisfied performance obligations. A term for purposes of these contracts has been estimated at 24 months. In addition, the Company applies the standard’s optional exemption to disclose information about performance obligations for contracts that have original expected terms of one year or less. For arrangements that include multiple performance obligations, the transaction price from the arrangement is allocated to each respective performance obligation based on its relative standalone selling price and recognized when revenue recognition criteria for each performance obligation are met. The standalone selling price for each performance obligation is established based on the sales price at which the Company would sell a promised good or service separately to a customer or the estimated standalone selling price. The Company’s incremental direct costs of obtaining a contract, which consist primarily of sales commissions, are generally deferred and amortized to sales and marketing expense over the estimated life of the relevant customer relationship of approximately 24 months and are subject to being monitored every period to reflect any significant change in assumptions. In addition, the deferred contract cost asset is assessed for impairment on a periodic basis. The Company’s contract acquisition costs are included in other assets, net in the balance sheet. The Company is applying the standard’s practical expedient permitting expensing of costs to obtain a contract when the expected amortization period is one year or less, which typically results in expensing commissions paid to acquire certain contracts. As of December 31, 2020 and March 31, 2021, the Company had $167,000 and $140,000 of net deferred contract costs, respectively, and the accumulated amortization associated with these costs was $989,000 and $1.1 million for the periods ended December 31, 2020 and March 31, 2021, respectively.
Stock-Based Compensation	The Company grants stock-based awards, including stock options, restricted stock awards, and restricted stock units. The Company measures stock-based compensation cost at the grant date based on the fair value of the award and recognizes it as expense over the vesting or service period, as applicable, of the stock-based award using the straight-line method. The Company accounts for forfeitures as they occur. The Company uses the Black-Scholes option pricing model to estimate the per share fair value of stock option grants with time-based vesting. The Black-Scholes model relies on a number of key assumptions to calculate estimated fair values. For the three months ended March 31, 2020 and 2021 the expected life of each award granted was determined based on historical experience with similar awards, giving consideration to contractual terms, anticipated exercise patterns, vesting schedules and expirations. Expected volatility is based on historical volatility levels of the Company’s Class B common stock and the expected volatility of companies in similar industries that have similar vesting and contractual terms. The risk-free interest rate is based on the implied yield currently available on U.S. Treasury issues with terms approximately equal to the expected life of the option.

Payments of principal and interest on the Loans will be deferred for a period in excess of six months. We expect this repayment commencement period to be in the middle part to latter half of 2021. Principal and interest are payable monthly commencing one month after the payment deferral period and may be prepaid by the Company at any time prior to maturity with no prepayment penalties. There are scenarios where, under the terms of the CARES Act, recipients can apply for and receive forgiveness for all, or a portion of the Loans issued. Such forgiveness will be determined, subject to limitations and conditions, based on the use of Loan proceeds for certain permissible purposes as set forth in the CARES Act, including, but not limited to, payroll, mortgage and rent costs. Due to the uncertainties concerning the anticipated timing of repayment that are not within our control as well as the evolving parameters and interpretations of requirements, these loans are presented as a current liability on our Condensed Consolidated Balance Sheets.

CARES Act Loans and Foreign Wage Subsidy

(13) CARES Act Loans and Foreign Wage Subsidy

During the second quarter of 2020, the Company secured $5.3 million in promissory notes to bank lenders pursuant to government loan programs (collectively, the “Loans”). At December 31, 2020 and March 31, 2021, the remaining balance was $5.1 million. The difference relates to the business operations divested in October 2020. The Loans were made under, and are subject to the terms and conditions of, the CARES Act and are administered by the U.S. Small Business Administration (“SBA”). The current terms of the Loans are two years with maturity dates in the second quarter of 2022 and they contain a fixed annual interest rate of 1%. Payments of principal and interest on the Loans will be deferred for a period in excess of six months. We expect this repayment commencement period to be in the middle part to latter half of 2021. Principal and interest are payable monthly commencing one month after the payment deferral period and may be prepaid by the Company at any time prior to maturity with no prepayment penalties. There are scenarios where, under the terms of the CARES Act, recipients can apply for and receive forgiveness for all, or a portion of the Loans issued. Such forgiveness will be determined, subject to limitations and conditions, based on the use of Loan proceeds for certain permissible purposes as set forth in the CARES Act, including, but not limited to, payroll, mortgage and rent costs. Due to the uncertainties concerning the anticipated timing of repayment that are not within our control as well as the evolving parameters and interpretations of requirements, these loans are presented as a current liability on our Condensed Consolidated Balance Sheets.

In addition, under foreign wage and rent subsidy programs in response to the COVID-19 pandemic, a subsidiary received approximately $151,000 in funding during the three months ended March 31, 2021 that were treated as reductions of payroll and related expenses.

Stockholders' Equity

(6) Stockholder’s Equity

Common Stock

In November 2014, the Company’s board of directors authorized a share repurchase program (the “2014 Repurchase Program”), which supersedes and replaces any prior repurchase programs. Under the 2014 Repurchase Program, the Company is authorized to repurchase up to 3 million shares of the Company’s Class B common stock in the aggregate through open market and privately negotiated transactions, at such times and in such amounts as the Company deems appropriate. Repurchases may also be made under a Rule 10b5-1 plan, which would permit shares to be repurchased when the Company might otherwise be precluded from doing so under insider trading laws. The timing and actual number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements, capital availability, and other market conditions. The 2014 Repurchase Program does not have an expiration date and may be expanded, limited or terminated at any time without prior notice. During the three months ended March 31, 2020 and 2021, the Company did not repurchase any Class B common stock.

Stock-based Compensation Plans

The Company grants stock-based awards, including stock options, restricted stock awards, and restricted stock units. The Company measures stock-based compensation cost at the grant date based on the fair value of the award and recognizes it as expense over the vesting or service period, as applicable, of the stock-based award using the straight-line method. The Company accounts for forfeitures as they occur.

Stock-based compensation expense was included in the following operating expense categories as follows (in thousands):

	Three Months Ended March 31,
	2020		2021
Service costs	$	16	$	8
Sales and marketing		261		229
Product development		81		97
General and administrative		604		410
Total stock-based compensation	$	962	$	744

The Company uses the Black-Scholes option pricing model to estimate the per share fair value of stock option grants with time-based vesting. The Black-Scholes model relies on a number of key assumptions to calculate estimated fair values. For the three months ended March 31, 2020 and 2021 the expected life of each award granted was determined based on historical experience with similar awards, giving consideration to contractual terms, anticipated exercise patterns, vesting schedules and expirations. Expected volatility is based on historical volatility levels of the Company’s Class B common stock and the expected volatility of companies in similar industries that have similar vesting and contractual terms. The risk-free interest rate is based on the implied yield currently available on U.S. Treasury issues with terms approximately equal to the expected life of the option.

The following weighted average assumptions were used in determining the fair value of time-vested stock option grants for the periods presented:

	Three months ended March 31,
	2020	2021
Expected life (in years)	4.0 - 6.25	4.0 - 6.25
Risk-free interest rate	1.13%-1.22%	0.64%-1.16%
Expected volatility	46%-52%	50%-56%

(9) Leases

The Company has an operating lease for office space for its corporate headquarters in Seattle, Washington. It also has operating leases for office space in Mississauga, Canada and Wichita, Kansas. The Company leases its office facilities under operating lease agreements in accordance with ASC 842 and recognizes rent expense on a straight-line basis over the lease term with any lease incentives amortized as a reduction of rent expense over the lease term.

The Company’s lease agreement with respect to office space in Seattle, Washington, as amended, expires on March 31, 2025. The Company has the option to terminate the lease in March 2023, subject to satisfaction of certain conditions, including a payment of a termination fee of approximately $671,000. In addition, as part of the agreement, the lessor paid towards the cost of certain leasehold improvements (“landlord contribution”) of which the Company could use approximately $180,000 of unused landlord contribution as a credit against any payment obligation under the lease. In the second quarter of 2019, the Company requested the $180,000 landlord contribution from the lessor as a reimbursement towards certain leasehold improvements and received those funds in the third quarter of 2019. In the first quarter of 2018, the lessor paid $373,000 towards certain leasehold improvements which the Company accounted for as a lease incentive and is amortizing as a reduction of rent expense over the lease term. Additionally, in April 2018, the lessor refunded the previously provided security deposit and the Company provided a letter of credit to the lessor in the amount of $575,000, which will be reduced by $100,000 annually starting in April 2019. Additionally, in the third quarter of 2020, the Company concluded that exercising its option to terminate this office lease in March 2023 had met the reasonably certain threshold and as such, the Company remeasured its ROU asset and liability associated with this lease as of September 30, 2020 based on the expected termination fee payment of approximately $671,000 and a lease termination date of March 2023.

The Company’s lease agreement with respect to office space in Mississauga, Canada commenced in November 2016, with a lease term of 60 months, expiring on November 30, 2021. The Company has the option to terminate the lease upon nine months’ notice without any termination fees if such notice is provided.

The Company commenced a new lease for an office space in Wichita, Kansas in June 2020 which continues for a period of 66 months with an option to extend the term for two additional periods of three years each. The Company has the option to terminate the lease pursuant to certain terms as specified in the lease without any termination fees if notice is provided.

Goodwill And Intangible Assets Disclosure [Abstract]

Goodwill

(12) Goodwill

The balance of goodwill as of December 31, 2020 and March 31, 2021 is $17.6 million. There were no changes in the carrying amount of goodwill for the three months ended March 31, 2021.

The Company performs its annual impairment testing on November 30 and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. When evaluating goodwill for impairment, the Company may first perform a qualitative assessment and determine if the fair value of the reporting unit is more likely than not greater than its carrying amount. For the three months ended March 31, 2020, the Company’s stock price was impacted by volatility in the U.S. financial markets as a result of the rapid spread of the coronavirus globally which has resulted in increased travel restrictions and disruption and shutdown of businesses, and traded below the then book value for an extended period of time. Accordingly, the Company tested its goodwill for impairment and concluded that the carrying value exceeded the estimated fair value of the Company’s single reporting unit and recognized an impairment loss during the first quarter of 2020 of $14.7 million. The Company tested its goodwill for impairment again upon the Divestiture and at November 30, 2020. No additional impairment loss was determined to have occurred. The impairment charges from the first quarter of 2020 are reflected in the Company’s Condensed Consolidated Statement of Operations for the three months ended March 31, 2020 within Impairment of goodwill. The estimated fair value of the Company’s single reporting unit was based on estimates of future operating results, discounted cash flows and other market-based factors, including the Company’s stock price. The goodwill impairment loss resulted primarily from a sustained decline in the Company’s common stock share price and market capitalization as well as lower projected revenue growth rates and profitability levels compared to historical results. The lower projected operating results reflect changes in assumptions related to organic revenue growth rates, market trends, business mix, cost structure, and other expectations about the anticipated short-term and long-term operating results.

The testing of goodwill for impairment requires the Company to make significant estimates about its future performance and cash flows, as well as other assumptions. Events and circumstances considered in determining whether the carrying value of goodwill may not be recoverable include, but are not limited to: significant changes in performance relative to expected operating results; significant changes in the use of the assets; significant changes in competition and market dynamics; significant and sustained declines in the Company’s stock price and market capitalization; a significant decline in its expected future cash flows or a significant adverse change in the Company’s business climate. These estimates and circumstances are inherently uncertain and can be affected by

numerous factors, including changes in economic, industry or market conditions, changes in business operations, a loss of a significant customer, changes in competition, volatility in financial markets, or changes in the share price of the Company’s Class B common stock and market capitalization. The Company will continue to monitor its financial performance, stock price and other factors in order to determine if there are any indicators of impairment prior to its annual impairment evaluation in November 2021.

Accounting Policies [Abstract]

Description of Business and Basis of Presentation

(1) Description of Business and Basis of Presentation

Description of Business

Marchex, Inc. (the “Company”) was incorporated in the state of Delaware on January 17, 2003. The Company is a conversational analytics and solutions company that helps businesses connect, drive, measure, and convert callers into customers, and connects the voice of the customer to their business. We deliver data insights and incorporate artificial intelligence (AI)-powered functionality that drives insights and solutions to help companies find, engage and support their customers across voice and text-based communication channels.

Divestiture

In October 2020, the Company sold its interests in certain assets related to its Local Leads Platform, Call Marketplace and other assets not related to core conversational analytics and sales engagement solutions. The purchaser is a related party controlled by a shareholder and officers of the Company. The assets met the definition of a business and represented a discontinued operation since the disposal enabled the Company to focus more wholly on its core conversational analytics and sales engagement solution activities, and it had a significant effect on the Company’s operations and financial results. The Company will have no further involvement in the key strategic decision making or operations of the business. As a result, the operating results related to these assets are shown as discontinued operations, net of tax, in the Condensed Consolidated Statements of Operations for the three months ended March 31, 2020. See Note 14. Discontinued Operations and Related Party Investment of the Notes to the Condensed Consolidated Financial Statements for further discussion. Unless otherwise indicated, information presented in the Notes to the Financial Statements relates only to the Company’s continuing operations.

The Impact of COVID-19 on our Business

In late 2019, an outbreak of COVID-19 emerged and by March 2020, was declared a global pandemic by the World Health Organization. Across the United States and the world, governments and municipalities instituted measures in an effort to control the spread of COVID-19, including quarantines, shelter-in-place orders, school closings, travel restrictions and the closure of non-essential businesses. By the end of March, the macroeconomic impacts became significant, exhibited by, among other things, a rise in unemployment and market volatility.

For most of the quarter ended March 31, 2020, the Company’s results reflect historical trends and seasonality. However, beginning in March 2020, the Company experienced a decline in revenues due to the impact of COVID-19 and the related reductions in global economic activity and reduced spending by its customers in response to the macroeconomic impact. During the quarter ended March 31, 2020, the Company also assessed the realized and potential credit deterioration of its customers due to changes in the macroeconomic environment, which has been reflected in an increase in its allowance for credit losses for accounts receivable as of March 31, 2020 and December 31, 2020. Additionally, the Company determined that indicators of impairment had occurred during the first quarter of 2020, which resulted in the Company performing an interim impairment analysis during the first quarter of 2020. As a result of this interim impairment test, the Company recognized an impairment of its intangible long-lived assets and goodwill during the first quarter of 2020. See the Note 11. Identifiable Intangible Assets from Acquisitions and Note 12. Goodwill in these Notes to the Condensed Consolidated Financial Statements for additional information.

For additional information for the effects of the COVID-19 pandemic and resulting global disruptions on the Company’s business and operations, refer to Item 2 of Part I, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Item 1.A of Part II, “Risk Factors”.

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading.

The preparation of our unaudited Condensed Consolidated Financial Statements requires management to make estimates and assumptions that affect the amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. The Company has used estimates

related to several financial statement amounts, including revenues, allowance for doubtful accounts, allowance for advertiser credits, useful lives for property and equipment and intangible assets, valuation of intangible assets, valuation of contingent consideration transferred as a result of business combinations, the fair value of the Company’s common stock and stock option awards, the impairment of goodwill and the valuation allowance for deferred tax assets. The inputs into our judgments and estimates consider the economic implications of COVID-19 on our critical and significant accounting estimates. Actual results could differ from those estimates.

Operating results for the three months ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021, or for any other period. The interim financial information is unaudited, and reflects all normal adjustments that are, in our opinion, necessary to provide a fair statement of results for the interim periods presented. The balance sheet at December 31, 2020 has been derived from the audited Consolidated Financial Statements at that date. This report should be read in conjunction with the Consolidated Financial Statements in our 2020 Form 10-K where we include additional information about our policies and the methods and assumptions used in our estimates.

Our Company consolidates all entities that we control by ownership of a majority voting interest. All inter-company transactions and balances have been eliminated in consolidation. Certain reclassifications have been made to the Condensed Consolidated Financial Statements in the prior periods to conform to the current period presentation.

Assets, liabilities and operations of foreign subsidiaries are recorded based on the functional currency of the entity. For a majority of our foreign operations, the functional currency is the U.S. dollar. Assets and liabilities denominated in other than the functional currency are remeasured each month with the remeasurement gain or loss recorded in other income and expense in the Condensed Consolidated Statements of Operations.

Recent Accounting Pronouncements Not Yet Effective

In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments — Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (ASU 2016-13), an ASU amending the impairment model for most financial assets and certain other instruments. Early adoption is permitted after December 15, 2018. The ASU must be adopted using a modified-retrospective approach. In November 2018, the FASB issued Accounting Standards Update No. 2018-19, Codification Improvements (Topic 326), Financial Instruments - Credit Losses (ASU 2018-19), an ASU intended to improve the Codification or correct its unintended application. The ASU is effective upon the adoption of the amendments in Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, with early adoption permitted after December 15, 2018. The Company does not expect adoption of ASU 2018-19 and ASU 2016-13 to have a material impact on its Condensed Consolidated Financial Statements. In addition, in May 2019, the FASB issued Accounting Standards Update No. 2019-05, Financial Instruments — Credit Losses (Topic 326), Targeted Transition Relief, (ASU 2019-05)), an ASU which provides ASU 2016-13 transition relief by providing entities with an alternative to irrevocably elect the fair value option for eligible financial assets measured at amortized cost upon adoption of the credit losses standard. To be eligible for the transition election, the existing financial asset must otherwise be both within the scope of the new credit losses standard and eligible for the applying the fair value option in ASC 825-10. The election must be applied on an instrument-by-instrument basis and is not available for either available-for-sale or held-to-maturity debt securities. The ASU is effective upon the adoption of the amendments in ASU 2016-13. In addition, in November 2019, the FASB issued Accounting Standards Update No. 2019-10, Financial Instruments - Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) - Effective Dates (ASU-2019-10), an ASU modifying the effective dates of various previous pronouncements. As the Company qualifies as a Smaller Reporting Company with the SEC, this ASU revised the effective date of ASU 2016-13 and ASU 2017-04 to fiscal years beginning after December 15, 2022. The Company does not expect adoption of ASU 2019-10 to have a material impact on our Consolidated Financial Statements. The Company does not expect adoption of ASU 2019-10, ASU 2019-05, ASU 2018-19 and ASU 2016-13 to have a material impact on its Consolidated Financial Statements.

In February 2020, the FASB issued Accounting Standards Update No. 2020-02, Financial Instruments — Credit Losses (Topic 326) and Leases (Topic 842). This ASU adds an SEC paragraph pursuant to the issuance of SEC Staff Accounting Bulletin No. 119, which adds Topic 6M on Accounting for Loan Losses by Registrants Engaged in Lending Activities Subject to FASB ASC Topic 326. It also adds a note in paragraph 842-10-S65-1 regarding the updated effective date for Leases pursuant to the issuance of ASU 2019-10. Additionally, in March 2020 Accounting Standards Update No. 2020-03, Codification Improvements to Financial Instruments (ASU 2020-03), an ASU which represent changes to clarify or improve the Codification. The amendments make the Codification easier to understand and easier to apply by eliminating inconsistencies and providing clarifications. The amendments and are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. The Company does not expect adoption of ASU 2020-02 and of ASU 2020-03 to have a material impact on our Consolidated Financial Statements.

In November 2019, the FASB issued Accounting Standards Update No. 2019-11, Codification Improvement to Topic 326, Financial Instruments — Credit Losses, an ASU which makes several amendments to the new credit losses standard, including an

amendment requiring entities to include certain expected recoveries of the amortized cost basis previously written off, or expected to be written off, in the allowance for credit losses for purchased credit deteriorated assets. The amendments also provide transition relief related to troubled debt restructurings, allow entities to exclude accrued interest amounts from certain required disclosures and clarify the requirements for applying the collateral maintenance practical expedient. For entities that have not yet adopted the new credit losses standard, the effective dates and transition requirements are the same as those in ASU 2016-13. For entities that have adopted the new credit losses standard, the amendments are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted in any interim period, as long as the entity has adopted the new credit losses standard. The ASU must be adopted using a modified-retrospective approach. The Company does not expect adoption of ASU 2019-11 to have a material impact on its Consolidated Financial Statements.

In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes, an ASU which eliminates certain exceptions to the guidance in Accounting Standards Codification (ASC or Codification) 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new guidance also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The guidance also clarifies that single-member limited liability companies and similar disregarded entities that are not subject to income tax are not required to recognize an allocation of consolidated income tax expense in their separate financial statements, but they could elect to do so. The ASU is effective for reporting periods beginning after December 15, 2020, with early adoption permitted. The transition method related to the ASU amendments depend upon the nature of the guidance and vary depending upon the specific amendment being implemented. The Company does not expect adoption of ASU 2019-12 to have a material impact on its Consolidated Financial Statements.

Revenue Recognition

3 Months Ended

Mar. 31, 2021

Revenue From Contract With Customer [Abstract]

Revenue Recognition

(2) Revenue Recognition

We generate the majority of our revenues from core analytics and solutions services. Customers typically receive the benefit of the Company’s services as they are performed and substantially all the Company’s revenue is recognized over time as the services are performed.

Revenue is recognized when a customer obtains control of services in an amount that reflects the consideration the Company expects to receive in exchange for those services. The Company measures revenue based on the consideration specified in the customer arrangement, and revenue is recognized when the performance obligations in the customer arrangement are satisfied. A performance obligation is a promise in a contract to transfer a distinct service or product to the customer. The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when or as the customer receives the benefit of the performance obligation.

The Company’s call analytics technology platform provides data and insights that can measure the performance of mobile, online and offline advertising for customers and small business resellers. The Company generates revenue from the Company’s call analytics technology platform when advertisers pay the Company a fee for each call/text or call/text related data element they receive from calls or texts or for each phone number tracked based on a pre-negotiated rate. Revenue is recognized as services are provided over time, which is generally measured by the delivery of each call/text or call/text related data element or each phone number tracked.

The majority of the Company’s customers are invoiced on a monthly basis following the month of the delivery of services and are required to make payments under standard credit terms. Collection on the related receivables may vary from reported information based upon third-party refinement of the estimated and reported amounts owed that occurs subsequent to period ends. The Company establishes an allowance for advertiser credits, which is included in Other accrued expenses and current liabilities in the balance sheet, using its best estimate of the amount of expected future reductions in advertisers’ payment obligations related to delivered services based on analysis of historical credits. The balance associated with the allowance for advertiser credits in the Company’s Condensed Consolidated Balance Sheet was $206,000 and $216,000 as of December 31, 2020 and March 31, 2021, respectively. Customer payments received in advance of revenue recognition are also contract liabilities and are recorded as deferred revenue. The deferred revenue balance in the Company’s Condensed Consolidated Balance Sheet as of December 31, 2020 and March 31, 2021 was $1.4 million and $1.3 million, respectively. During the three months ended March 31, 2020 and 2021, revenue recognized that was included in the contract liabilities balances at the beginning of the period was $503,000 and $749,000, respectively.

The majority of the Company’s total revenue is derived from contracts that include consideration that is variable in nature. The variable elements of these contracts primarily include the number of transactions (for example, the number qualified phone calls). For contracts with an effective term greater than one year, the Company applies the standard’s practical expedient that permits the exclusion of disclosure of the value of unsatisfied performance obligations for these contracts as the Company’s right to consideration corresponds directly to the value provided to the customer for services completed to date and all future variable consideration is allocated to wholly unsatisfied performance obligations. A term for purposes of these contracts has been estimated at 24 months. In addition, the Company applies the standard’s optional exemption to disclose information about performance obligations for contracts that have original expected terms of one year or less.

For arrangements that include multiple performance obligations, the transaction price from the arrangement is allocated to each respective performance obligation based on its relative standalone selling price and recognized when revenue recognition criteria for each performance obligation are met. The standalone selling price for each performance obligation is established based on the sales price at which the Company would sell a promised good or service separately to a customer or the estimated standalone selling price.

The Company’s incremental direct costs of obtaining a contract, which consist primarily of sales commissions, are generally deferred and amortized to sales and marketing expense over the estimated life of the relevant customer relationship of approximately 24 months and are subject to being monitored every period to reflect any significant change in assumptions. In addition, the deferred contract cost asset is assessed for impairment on a periodic basis. The Company’s contract acquisition costs are included in other assets, net in the balance sheet. The Company is applying the standard’s practical expedient permitting expensing of costs to obtain a contract when the expected amortization period is one year or less, which typically results in expensing commissions paid to acquire certain contracts. As of December 31, 2020 and March 31, 2021, the Company had $167,000 and $140,000 of net deferred contract costs, respectively, and the accumulated amortization associated with these costs was $989,000 and $1.1 million for the periods ended December 31, 2020 and March 31, 2021, respectively.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Identifiable Intangible Assets from Acquisitions

(11) Identifiable Intangible Assets from Acquisitions

For the three months ended March 31, 2020, our stock price was impacted by volatility in the U.S. financial markets as a result of the rapid spread of the coronavirus globally which has resulted in increased travel restrictions and disruption and shutdown of businesses, and traded below the then book value for an extended period of time. As a result, the Company performed an interim impairment test of our long-lived intangible assets using an undiscounted cash flow analysis pursuant to ASC 360, Property, Plant, and Equipment to determine if the cash flows expected to be generated by the asset groups over the estimated remaining useful life of the primary assets were sufficient to recover the carrying value of the asset groups, which were determined to be at the acquisition level. Based on this analysis, which included evaluating various cash flow scenarios, the undiscounted cash flows were not sufficient to recover the carrying value of the groups. As a result, the Company was required to determine the fair value of each asset group. To estimate the fair value, the Company utilized both the cost recovery and income approach, which is based on a discounted cash flow (DCF) analysis and calculates the fair value by estimating the after-tax cash flows attributable to the asset group and then discounting the after-tax cash flows to present value using a risk-adjusted discount rate. Assumptions used in the DCF require significant judgment, including judgment about appropriate discount rates and terminal values, growth rates, and the amount and timing of expected future cash flows. The forecasted cash flows are based on the Company's most recent strategic plan and for periods beyond the strategic plan and the Company's estimates were based on assumed growth rates expected as of the measurement date. The Company believes its assumptions were consistent with the plans and estimates that a market participant would use to manage the business.

Based on the results of this testing, the Company recorded pre-tax non-cash impairment totaling $5.0 million in the first quarter of 2020 relating to customer relationships, technologies, non-compete agreements and tradenames. These charges are reflected in the Company’s Condensed Consolidated Statement of Operations for the three-month period ended March 31, 2020.

Identifiable intangible assets from acquisitions consisted of the following (in thousands):

	As of December 31, 2020
	Gross Carrying Amount		Accumulated Amortization			Impairment			Net Carrying Amount
Customer relationships	$	13,018	$	(4,693	)	$	(3,430	)	$	4,895
Technologies		9,369		(4,731	)		(1,062	)		3,576
Non-compete agreements		3,409		(2,413	)		(346	)		650
Tradenames		734		(538	)		(121	)		75
Total identifiable intangible assets from acquisitions	$	26,530	$	(12,375	)	$	(4,959	)	$	9,196

	As of March 31, 2021
	Gross Carrying Amount		Accumulated Amortization			Impairment			Net Carrying Amount
Customer relationships	$	13,018	$	(5,189	)	$	(3,430	)	$	4,399
Technologies		9,369		(5,336	)		(1,062	)		2,971
Non-compete agreements		3,409		(2,474	)		(346	)	$	589
Tradenames		734		(557	)		(121	)		56
Total identifiable intangible assets from acquisitions	$	26,530	$	(13,556	)	$	(4,959	)	$	8,015

Amortizable intangible assets are amortized on a straight-line basis over their useful lives. Customer relationships, acquired technologies, tradenames, and non-compete agreements have a weighted average useful life from date of purchase of 5 years, 3 years, 2 years, 1-2 years, respectively. Aggregate amortization expense incurred by the Company for the three months ended March 31, 2020 and 2021 was approximately $1.8 million and $1.2 million, respectively. Based upon the current amount of acquired identifiable intangible assets subject to amortization, the estimated amortization expense for the next five years is as follows: $3.3 million in 2021, $2.1 million in 2022, $2.0 million in 2023, and $602,000 in 2024.
