Organization Consolidation And Presentation Of Financial Statements [Abstract]

Description of Business and Basis of Presentation

(1) Description of Business and Basis of Presentation

Marchex, Inc. (the “Company”) was incorporated in the state of Delaware on January 17, 2003. The Company is a call analytics company that helps businesses connect, drive, measure, and convert callers into customers. The Company provides products and services for businesses of all sizes that depend on consumer phone calls or texts to drive sales. The Company’s analytics technology can facilitate call quality and texting, analyze calls and measure the outcomes of calls. The Company also delivers performance-based, pay-for-call advertising across numerous mobile and online publishers to connect consumers with businesses over the phone.

The accompanying unaudited condensed consolidated financial statements of Marchex, Inc. and its wholly-owned subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by generally accepted accounting principles for annual financial statements. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019, or for any other period. The balance sheet at December 31, 2018 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and notes required by accounting principles generally accepted in the United States of America for complete financial statements. These condensed consolidated financial statements and notes should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes included in the Annual Report on Form 10-K for the year ended December 31, 2018, as amended, and filed with the SEC.

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company transactions and balances have been eliminated in consolidation. Certain reclassifications have been made to the consolidated financial statements in the prior periods to conform to the current period presentation.

Acquisitions

In November 2018, we acquired Telmetrics Inc. (“Telmetrics”), an enterprise call and text tracking and analytics company, and SITA Laboratories, Inc. (d/b/a Callcap) (“Callcap”), a call monitoring and analytics solutions company. See Note 10. Acquisitions of the notes to the condensed consolidated financial statements for further discussion.

Accounting Policies [Abstract]

Significant Accounting Policies

(2) Significant Accounting Policies

The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These judgments are difficult as matters that are inherently uncertain directly impact their valuation and accounting. Actual results may vary from management’s estimates and assumptions.

Except for the changes below, the Company has consistently applied the accounting policies to all periods presented in these condensed consolidated financial statements.

FASB ASC Topic 842, Leases, (ASC 842) is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. If an entity chooses the second option, the transition requirements for existing leases also apply to leases entered into between the date of initial application and the effective date. The entity must also recast its comparative period financial statements and provide the disclosures required by the new standard for the comparative periods. The new standard was effective for the Company on January 1, 2019. The Company adopted the new standard on January 1, 2019 and used the effective date as its date of initial application. Consequently, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019. The new standard provides a number of optional practical expedients in transition. The Company elected the ‘package of practical expedients’, which permits it not to reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs.

The primary impact upon adoption of the standard relates to the recognition of new right-of-use (ROU) assets and lease liabilities on the Company’s balance sheet for its office and operating leases and providing significant new disclosures about its leasing activities. On adoption, the Company recognized additional operating lease liabilities of approximately $8.7 million based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases and right-of-use (ROU) assets of approximately $7.4 million.

The new standard also provides practical expedients for an entity’s ongoing accounting. The Company elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, the Company did not recognize ROU assets or lease liabilities, and this included not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. The Company also elected the practical expedient to not separate lease and non-lease components for all of its leases.

Recent Accounting Pronouncement(s) Not Yet Effective

In August 2018, the FASB issued Accounting Standards Update No. 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40) – Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract (ASU 2018-15), an ASU which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to be capitalized. The ASU is effective for reporting periods beginning after December 15, 2019, with early adoption permitted. The Company does not expect adoption of ASU 2018-15 to have a material impact on its consolidated financial statements.

In August 2018, the FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13), an ASU which modifies the disclosure requirements on fair value measurements in ASC 820. The ASU is effective for reporting periods beginning after December 15, 2019, with early adoption permitted. The Company does not expect adoption of ASU 2018-13 to have a material impact on its consolidated financial statements.

In January 2017, the FASB issued Accounting Standards Update No 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (ASU 2017-04). ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating “Step 2” from the goodwill impairment test. ASU 2017-04 is effective for public companies’ annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company does not expect adoption of ASU 2017-04 to have a material impact on its consolidated financial statements.

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. The ASU is effective for reporting periods beginning after December 15, 2019, with early adoption 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, which is effective for reporting periods beginning after December 15, 2019, 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 consolidated financial statements.

Revenue From Contract With Customer [Abstract]

Revenue Recognition

(3) Revenue Recognition

The Company generates the majority of its revenues from advertisers for its performance based advertising services, which include the use of its call analytics technology and pay-for-call advertising products and services. The Company’s revenue also consists of payments from its reseller partners for use of its local leads platform and marketing services, which they offer to their small business customers. 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.

The Company adopted FASB ASC Topic 606, Revenue from Contracts with Customers, (ASC 606) on January 1, 2018 using the modified retrospective approach for all contracts not completed as of the date of initial application, referred to as open contracts. Therefore, the comparative information has not been adjusted and continues to be reported under ASC 605. Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration we expect to receive in exchange for those goods or 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 primary impact upon adoption of the standard relates to the deferral (i.e. capitalization) of incremental contract acquisition costs which are recorded as other non-current assets in the balance sheet and the recognition (i.e. amortization) of them in sales and marketing expenses in the statements of operations over the term of the initial contract and anticipated renewal contracts to which the costs relate. The Company recognized a $189,000 decrease to accumulated deficit as of January 1, 2018 for the cumulative impact of adoption of the amended guidance associated with the incremental contract acquisition costs on open contracts that were capitalized. The impact of the adoption of ASC 606 on net loss applicable to common stockholders for the year ended December 31, 2018 and on the unaudited consolidated balance sheet at December 31, 2018 was not significant.

The Company’s call analytics technology platform provides data and insights that can measure the performance of mobile, online and offline advertising for advertisers 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 including call-based ads the Company distributes through its sources of call distribution 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 Company’s call marketplace offers advertisers and adverting service providers’ ad placements across the Company’s distribution network. Advertisers or advertising service providers are charged on a pay-per-call or cost-per-action basis. The Company generates revenue upon delivery of qualified and reported phone calls to advertisers or advertising service providers’ listings. These advertisers and advertising service providers pay the Company a designated transaction fee for each qualified phone call, which occurs when a user makes a phone call, clicks, or completes a specified action on any of their advertisement listings after it has been placed by the Company or by the Company’s distribution partners. The Company also generates revenue from cost-per-action services, which occurs when a user makes a phone call from the Company’s advertiser’s listing or is redirected from one of the Company’s web sites or a third-party web site in the Company’s distribution network to an advertiser web site and completes the specified action. Each qualified phone call or specified action on a listing represents a completed transaction. Revenue is recognized as services are provided upon the delivery of a qualified phone call or completed action. The Company’s distribution network is primarily comprised of third party mobile and online search engines and applications, mobile carriers, directories, destination sites, shopping engines, Internet domains or web sites, other targeted Web-based content, and offline sources. The Company enters into agreements with these third-party distribution partners to provide distribution for pay-for-call advertisement listings, which contain call tracking numbers and/or URL strings. The Company generally pays distribution partners based on a percentage of revenue or a fixed amount per phone call or other actions on these listings. The Company acts as the principal with the advertiser for revenue call transactions and is responsible for the fulfillment of services. The Company recognizes revenue for these fees under the gross revenue recognition method.

The Company’s local leads platform allows reseller partners to sell call advertising, search marketing, and other lead generation products through their existing sales channels to small business advertisers. The Company generates revenue from reseller partners utilizing the Company’s local leads platform and is paid account fees and/or agency fees for the Company’s products in the form of a percentage of the cost of every call or click delivered to advertisers. Revenue is recognized over time as services are provided. The reseller partners engage the advertisers and are the principal for the transaction, and the Company, in certain instances, is only financially liable to the publishers in the Company’s capacity as a collection agency for the amount collected from the advertisers. The Company recognizes revenue for these fees under the net revenue recognition method. In limited arrangements resellers pay the Company a fee for fulfilling an advertiser’s campaign in its distribution network and the Company acts as the principal and recognizes revenue for these fees under the gross revenue recognition method.

For the three months ended March 31, 2018, revenues disaggregated by service type were $19.9 million for performance based advertising services and $2.0 million for local leads services. For the three months ended March 31, 2019, revenues disaggregated by service type were $25.2 million for performance based advertising services and $1.2 million for local leads services.

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. The Company establishes an allowance for advertiser credits, which is included in accrued expense and other current liabilities in the balance sheet as of March 31, 2019, 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. Customer payments received in advance of revenue recognition are contract liabilities and are recorded as deferred revenue. During the three months ended March 31, 2019, revenue recognized that was included in the contract liabilities balance at the beginning of the period was $349,000.

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.

In certain cases, the Company records revenue based on available and reported preliminary information from third parties. 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’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 March 31, 2019, the Company had $247,000 of net deferred contract costs and the amortization associated with these costs was $108,000 for the three months ended March 31, 2019.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]

Stock-based Compensation Plans

(4) 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,
	2018		2019
Service costs	$	128	$	59
Sales and marketing		214		177
Product development		91		76
General and administrative		518		233
Total stock-based compensation	$	951	$	545

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, 2018 and 2019, 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. For the three months ended March 31, 2018, the Company used an expected dividend yield for those grants prior to the record date of the Company’s common stock cash dividend payment in March 2018.

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,
	2018	2019
Expected life (in years)	4.0	4.0
Risk-free interest rate	2.54%	2.22%
Expected volatility	53%	40%
Expected dividend yield	0% - 3.57%	0%

Stock option activity during the three months ended March 31, 2019 is summarized as follows:

	Shares (in thousands)			Weighted average exercise price		Weighted average remaining contractual term (in years)
Balance at December 31, 2018		5,511		$	4.98		5.53
Options granted		110			4.03
Options forfeited		(160	)		3.23
Options expired		(123	)		5.90
Options exercised		(55	)		3.30
Balance at March 31, 2019		5,283		$	5.01		5.05

Restricted stock awards and restricted stock units are generally measured at fair value on the date of grant based on the number of awards granted and the quoted price of the Company’s common stock. Restricted stock units entitle the holder to receive one share of the Company’s Class B common stock upon satisfaction of certain service conditions.

Restricted stock awards and restricted stock unit activity during the three months ended March 31, 2019 is summarized as follows:

	Shares/ Units (in thousands)			Weighted average grant date fair value

Earnings Per Share [Abstract]

Net Income (Loss) Per Share

(5) 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.

In certain cases, the Company may engage directly with one or more advertising agencies who act on an advertiser’s behalf. In addition, an advertising agency may represent more than one advertiser that utilizes the Company’s products and services. One advertising agency represented 20% and 14% of revenue for the three months ended March 31, 2018 and 2019, respectively. This same advertising agency represented 23% and 29% of accounts receivable as of December 31, 2018 and March 31, 2019, respectively.

A significant amount of the Company’s revenue earned from advertisers is generated through arrangements with distribution partners. The Company may not be successful in renewing any of these agreements, or, if they are renewed, they may not be on terms as favorable as current arrangements. The Company may not be successful in entering into agreements with new distribution partners or advertisers on commercially acceptable terms. In addition, several of these distribution partners or advertisers may be considered potential competitors. There were no distribution partners paid more than 10% of revenue for the three months ended March 31, 2018 and 2019.

Leases

(9) Leases

The Company leases office space for its corporate headquarters in Seattle, WA. It also leases an 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, the lessor will pay towards the cost of certain leasehold improvements (“landlord contribution”) of which the Company may use up to approximately $180,000 of any unused landlord contribution as a credit against any payment obligation under the lease. 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. The letter of credit was collateralized by a $575,000 certificate of deposit, which was restricted in use and is included in other assets in the Company’s condensed consolidated balance sheet as of December 31, 2018 and March 31, 2019. On April 2, 2019, the Company was no longer required to collateralize the letter of credit and the certificate of deposit matured.

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’s lease agreement with respect to office space in Wichita, Kansas is on a month-to-month basis. The lease agreement stipulates a mutual 120-day non-cancelable period to cease rental payments and vacate the premises, and is classified as a short-term operating lease. Short-term leases are leases having a term of twelve months or less.

Lease cost recognized in the Company’s consolidated statements of operations and other information is summarized as follows (in thousands):

	Three months ended March 31, 2019

In connection with the Telmetrics acquisition in 2018, the Company has an earnout arrangement that requires the Company to pay up to a maximum of $3.0 million in cash based upon the achievement of targeted financial goals over the two (2) twelve (12) month periods following the acquisition date. The estimated fair value of the contingent consideration arrangement is approximately $1.6 million and is recorded on the balance sheet in acquisition-related liabilities as of March 31, 2019.

During the three months ended March 31, 2019, the Company committed $2.5 million in funding for a strategic technology initiative over the next 12 months.

(b) 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 our contract parties to seek to minimize the impact of any associated litigation in which they may be involved. To date, there have been no known events or circumstances that have resulted in any material costs related to these indemnification provisions and no liabilities therefore have been recorded in the accompanying consolidated financial statements. However, the maximum potential amount of the future payments we could be required to make under these indemnification 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.

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, 2018 and March 31, 2019. 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.

Acquisitions

(11) Acquisitions

(a) Telmetrics Acquisition:

In November 2018, the Company acquired 100% of the outstanding stock of Telmetrics, an enterprise call

and text tracking and analytics company based in Canada for total consideration consisting of the following:

•

Approximately $10.1 million in cash, paid at closing; and

•

Up to $3.0 million in cash based upon the achievement of targeted financial goals over the two (2) twelve (12) month periods following the acquisition date.

The Company accounted for the Telmetrics acquisition as a business combination. As a result of the

acquisition, the Company captured additional scale with its call analytics business and enhanced text communications product initiatives.

A summary of the consideration for the acquisition is as follows (in thousands):

Cash	$	10,100
Future consideration		1,600
Total	$	11,700

The future consideration includes an earnout arrangement that requires the Company to pay up to a maximum of $3.0 million in cash to the former shareholders of Telmetrics based upon the achievement of targeted financial goals over the two (2) twelve (12) month periods following the acquisition date. The potential undiscounted amount of all future payments that the Company could be required to make under the contingent earnout arrangement is between $0 and $3.0 million. Of the $3.0 million possible earnout, $450,000 may be paid to certain employees to the extent they remain employed by the Company on the first and second anniversaries following the acquisition date. Such amounts have been excluded from the purchase consideration and are treated as compensation expense. The fair value of the contingent consideration arrangement of approximately $1.6 million was estimated by applying the income approach, which is based on significant inputs that are not observable in the market (Level 3 inputs), such as the discount rate and the probability of meeting targeted financial goals. As of March 31, 2019, the range of outcomes, and the assumptions used to develop the estimates had not changed. The earnout liability is recorded on the balance sheet in acquisition-related liabilities.

In connection with the acquisition, a portion of the cash consideration was placed in escrow to secure indemnification obligations for a period of 18 months from the closing date. The escrow amounts are included as part of the purchase price consideration and will ultimately be released in the event no indemnification obligations are identified. In the event any indemnification obligations are identified, the purchase price may be reduced accordingly. The consideration is preliminary pending finalization of potential working capital adjustments.

The following summarizes the preliminary estimated fair value of the assets acquired and the liabilities assumed as of March 31, 2019 (in thousands):

Cash and cash equivalents	$	359
Accounts receivable		1,274
Prepaid expenses and other current assets	586
Property and equipment	281
Identifiable intangible assets		6,351
Liabilities assumed		(885	)
Deferred tax liabilities		(1,677	)
Net assets acquired		6,289
Goodwill		5,411
Total	$	11,700

The acquired identifiable intangible assets of approximately $6.4 million consist primarily of customer relationships, technology, tradenames, and non-compete agreements which will be amortized over 24 to 60 months (weighted average of 3.6 years) using the straight-line method. Goodwill represents the expected synergies with our existing business, the acquired assembled workforce, potential new customers and future cash flows after the acquisition of Telmetrics. The goodwill is not anticipated to be deductible for Canadian tax purposes.

(b) Callcap Acquisition:

In November 2018, the Company acquired 100% of the outstanding stock of Callcap, a call monitoring and

analytics solutions company based in Kansas for total consideration of $35.0 million, consisting of the following:

•

Approximately $25.0 million in cash, and

•

3.4 million shares of Class B common stock valued at approximately $10.0 million, to be issued over the four-year period following the acquisition date. The issuance of the Class B common stock is not contingent.

The Company accounted for the Callcap acquisition as a business combination. As a result of the

acquisition, the Company expanded its customer base, as well as enhanced its growth opportunities in verticals and new customer channels, such as the small business segment.

A summary of the consideration for the acquisition is as follows (in thousands):

Cash	$	24,993
Fair value of equity consideration		10,017
Total	$	35,010

The fair value of the 3.4 million shares of Class B common stock to be issued over the four-year period

following the acquisition date, was calculated based on the closing price of Marchex’s Common Stock on Nasdaq on the acquisition date and is recorded on the Company’s balance sheet within additional paid-in capital.

In connection with the acquisition, a portion of the cash and equity consideration was (or will be on issuance) placed in escrow to secure indemnification obligations for a period of 18 months from the closing date. The escrow amounts are included as part of the purchase price consideration and will ultimately be released in the event no indemnification obligations are identified. In the event any indemnification obligations are identified, the purchase price may be reduced accordingly.

The following summarizes the preliminary estimated fair value of the assets acquired and the liabilities assumed as of March 31, 2019 (in thousands):

Cash and cash equivalents	$	490
Accounts receivable		246
Prepaid expenses and other current assets		504
Property and equipment		93
Identifiable intangible assets		15,128
Liabilities assumed		(482	)
Net assets acquired		15,979
Goodwill		19,031
Total	$	35,010

The acquired identifiable intangible assets of approximately $15.1 million consist primarily of customer relationships, tradenames, technologies, and non-compete agreements, which will be amortized over their preliminary estimated useful lives ranging from 24 to 60 months (weighted average of 4.1 years) using the straight-line method. Goodwill represents the expected synergies with our existing business, the acquired assembled workforce, potential new customers and future cash flows after the acquisition of Callcap. The goodwill is deductible for federal tax purposes.

The following unaudited pro forma financial information summarizes the combined results of operations of the Company, Telmetrics, and Callcap, and is based on the historical results of operations of the Company, Telmetrics, and Callcap.

Goodwill

(13) Goodwill

There was no change in goodwill for the three months ended March 31, 2019.

We perform our annual impairment testing on November 30 and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. No impairment of goodwill has been identified in 2019. 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.

(14) 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, 2019, the Company repurchased 90,000 shares of Class B common stock for approximately $900 (employee restricted equity subject to vesting repurchased for $.01 per share upon termination of employment), which was not pursuant to the 2014 Repurchase Program. The Company did not repurchase any Class B common stock during the three months ended March 31, 2018.

Accounting Policies [Abstract]
Accompanying Unaudited Condensed Consolidated Financial Statements	The accompanying unaudited condensed consolidated financial statements of Marchex, Inc. and its wholly-owned subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by generally accepted accounting principles for annual financial statements. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019, or for any other period. The balance sheet at December 31, 2018 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and notes required by accounting principles generally accepted in the United States of America for complete financial statements. These condensed consolidated financial statements and notes should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes included in the Annual Report on Form 10-K for the year ended December 31, 2018, as amended, and filed with the SEC. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company transactions and balances have been eliminated in consolidation. Certain reclassifications have been made to the consolidated financial statements in the prior periods to conform to the current period presentation. Acquisitions In November 2018, we acquired Telmetrics Inc. (“Telmetrics”), an enterprise call and text tracking and analytics company, and SITA Laboratories, Inc. (d/b/a Callcap) (“Callcap”), a call monitoring and analytics solutions company. See Note 10. Acquisitions of the notes to the condensed consolidated financial statements for further discussion.
Recent Accounting Pronouncement(s) Not Yet Effective	Recent Accounting Pronouncement(s) Not Yet Effective In August 2018, the FASB issued Accounting Standards Update No. 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40) – Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract (ASU 2018-15), an ASU which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to be capitalized. The ASU is effective for reporting periods beginning after December 15, 2019, with early adoption permitted. The Company does not expect adoption of ASU 2018-15 to have a material impact on its consolidated financial statements. In August 2018, the FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13), an ASU which modifies the disclosure requirements on fair value measurements in ASC 820. The ASU is effective for reporting periods beginning after December 15, 2019, with early adoption permitted. The Company does not expect adoption of ASU 2018-13 to have a material impact on its consolidated financial statements. In January 2017, the FASB issued Accounting Standards Update No 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (ASU 2017-04). ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating “Step 2” from the goodwill impairment test. ASU 2017-04 is effective for public companies’ annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company does not expect adoption of ASU 2017-04 to have a material impact on its consolidated financial statements. 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. The ASU is effective for reporting periods beginning after December 15, 2019, with early adoption 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, which is effective for reporting periods beginning after December 15, 2019, 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 consolidated financial statements.
Revenue Recognition	Revenue Recognition The Company generates the majority of its revenues from advertisers for its performance based advertising services, which include the use of its call analytics technology and pay-for-call advertising products and services. The Company’s revenue also consists of payments from its reseller partners for use of its local leads platform and marketing services, which they offer to their small business customers. 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. The Company adopted FASB ASC Topic 606, Revenue from Contracts with Customers, (ASC 606) on January 1, 2018 using the modified retrospective approach for all contracts not completed as of the date of initial application, referred to as open contracts. Therefore, the comparative information has not been adjusted and continues to be reported under ASC 605. Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration we expect to receive in exchange for those goods or 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 primary impact upon adoption of the standard relates to the deferral (i.e. capitalization) of incremental contract acquisition costs which are recorded as other non-current assets in the balance sheet and the recognition (i.e. amortization) of them in sales and marketing expenses in the statements of operations over the term of the initial contract and anticipated renewal contracts to which the costs relate. The Company recognized a $189,000 decrease to accumulated deficit as of January 1, 2018 for the cumulative impact of adoption of the amended guidance associated with the incremental contract acquisition costs on open contracts that were capitalized. The impact of the adoption of ASC 606 on net loss applicable to common stockholders for the year ended December 31, 2018 and on the unaudited consolidated balance sheet at December 31, 2018 was not significant. The Company’s call analytics technology platform provides data and insights that can measure the performance of mobile, online and offline advertising for advertisers 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 including call-based ads the Company distributes through its sources of call distribution 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 Company’s call marketplace offers advertisers and adverting service providers’ ad placements across the Company’s distribution network. Advertisers or advertising service providers are charged on a pay-per-call or cost-per-action basis. The Company generates revenue upon delivery of qualified and reported phone calls to advertisers or advertising service providers’ listings. These advertisers and advertising service providers pay the Company a designated transaction fee for each qualified phone call, which occurs when a user makes a phone call, clicks, or completes a specified action on any of their advertisement listings after it has been placed by the Company or by the Company’s distribution partners. The Company also generates revenue from cost-per-action services, which occurs when a user makes a phone call from the Company’s advertiser’s listing or is redirected from one of the Company’s web sites or a third-party web site in the Company’s distribution network to an advertiser web site and completes the specified action. Each qualified phone call or specified action on a listing represents a completed transaction. Revenue is recognized as services are provided upon the delivery of a qualified phone call or completed action. The Company’s distribution network is primarily comprised of third party mobile and online search engines and applications, mobile carriers, directories, destination sites, shopping engines, Internet domains or web sites, other targeted Web-based content, and offline sources. The Company enters into agreements with these third-party distribution partners to provide distribution for pay-for-call advertisement listings, which contain call tracking numbers and/or URL strings. The Company generally pays distribution partners based on a percentage of revenue or a fixed amount per phone call or other actions on these listings. The Company acts as the principal with the advertiser for revenue call transactions and is responsible for the fulfillment of services. The Company recognizes revenue for these fees under the gross revenue recognition method. The Company’s local leads platform allows reseller partners to sell call advertising, search marketing, and other lead generation products through their existing sales channels to small business advertisers. The Company generates revenue from reseller partners utilizing the Company’s local leads platform and is paid account fees and/or agency fees for the Company’s products in the form of a percentage of the cost of every call or click delivered to advertisers. Revenue is recognized over time as services are provided. The reseller partners engage the advertisers and are the principal for the transaction, and the Company, in certain instances, is only financially liable to the publishers in the Company’s capacity as a collection agency for the amount collected from the advertisers. The Company recognizes revenue for these fees under the net revenue recognition method. In limited arrangements resellers pay the Company a fee for fulfilling an advertiser’s campaign in its distribution network and the Company acts as the principal and recognizes revenue for these fees under the gross revenue recognition method. For the three months ended March 31, 2018, revenues disaggregated by service type were $19.9 million for performance based advertising services and $2.0 million for local leads services. For the three months ended March 31, 2019, revenues disaggregated by service type were $25.2 million for performance based advertising services and $1.2 million for local leads services. 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. The Company establishes an allowance for advertiser credits, which is included in accrued expense and other current liabilities in the balance sheet as of March 31, 2019, 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. Customer payments received in advance of revenue recognition are contract liabilities and are recorded as deferred revenue. During the three months ended March 31, 2019, revenue recognized that was included in the contract liabilities balance at the beginning of the period was $349,000. 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. In certain cases, the Company records revenue based on available and reported preliminary information from third parties. 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’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 March 31, 2019, the Company had $247,000 of net deferred contract costs and the amortization associated with these costs was $108,000 for the three months ended March 31, 2019.
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, 2018 and 2019, 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. For the three months ended March 31, 2018, the Company used an expected dividend yield for those grants prior to the record date of the Company’s common stock cash dividend payment in March 2018.
