Description of Business and Summary of Significant Accounting Policies and Practices

(1) Description of Business and Summary of Significant Accounting Policies and Practices

(a) 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 mobile advertising and analytics company that helps connect online behavior to real-world, offline actions. The Company provides products and services for businesses that focus on consumer phone calls to drive sales. The Company’s technology can facilitate call quality, analyze phone calls in real time and measure the outcomes of calls while its technology platform delivers performance-based, pay-for-call advertising across numerous mobile and online publishers to connect consumers with businesses over the phone.

The 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.

In July 2013, the Company sold certain assets related to Archeo’s pay-per-click advertising services and, in April 2015, the Company sold certain assets related to Archeo’s domain operations, including the bulk of its domain name portfolio. The operating results related to these dispositions are shown as discontinued operations in the consolidated statements of operations for all periods presented. In December 2015, the Company sold the remaining Archeo operations. The December 2015 disposition did not meet the criteria for discontinued operations, and as a result the operating results are reflected in continuing operations. See Note 10. Discontinued Operations and Disposition of the Notes to Consolidated Financial Statements for further discussion. Unless otherwise indicated, information presented in the Notes to Consolidated Financial Statements relates only to the Company’s continuing operations.

(b) Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. Cash equivalents consist primarily of money market funds.

(c) Fair Value of Financial Instruments

The Company had the following financial instruments as of December 31, 2014 and 2015: cash and cash equivalents, accounts receivable, refundable taxes, accounts payable and accrued liabilities. The carrying value of these financial instruments approximates their fair value based on the liquidity of these financial instruments and their short-term nature.

(d) Accounts Receivable

Accounts receivable are recorded at the invoiced amount and do not bear interest. Accounts receivable balances are presented net of allowance for doubtful accounts and allowance for advertiser credits.

Allowance for Doubtful Accounts

The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in existing accounts receivable. The Company determines the allowance based on analysis of historical bad debts, advertiser concentrations, advertiser credit-worthiness and current economic trends. Past due balances over 90 days and specific other balances are reviewed individually for collectability. The Company reviews the allowance for collectability quarterly. Account balances are written off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.

The allowance for doubtful accounts activity for the periods indicated is as follows (in thousands):


	Balance at beginning of period		Charged to costs and expenses		Write-offs, net of recoveries		Balance at end of period
December 31, 2013	$	577	$	772	$	728	$	621
December 31, 2014		621		256		294		583
December 31, 2015		583		61		160		484

Allowance for Advertiser Credits

The allowance for advertiser credits is the Company’s best estimate of the amount of expected future reductions in advertisers’ payment obligations related to delivered services. The Company determines the allowance for advertiser credits and adjustments based on analysis of historical credits.

The allowance for advertiser credits activity for the periods indicated is as follows (in thousands):


	Balance at beginning of period		Additions charged against revenue		Credits processed		Balance at end of period
December 31, 2013	$	585	$	994	$	870	$	709
December 31, 2014		709		1,257		948		1,018
December 31, 2015		1,018		263		756		525

(e) Property and Equipment

Property and equipment are stated at cost. Depreciation on computers and other related equipment, purchased and internally developed software, and furniture and fixtures is calculated on the straight-line method over the estimated useful lives of the assets, generally averaging three years. Leasehold improvements are amortized straight-line over the shorter of the lease term or estimated useful lives of the assets ranging from three to eight years.

(f) Goodwill

Goodwill represents the excess of the purchase price over the fair value of identifiable assets acquired and liabilities assumed in business combinations accounted for under the purchase method.

The Company applies the provisions of FASB ASC 350 “Goodwill and Intangible Assets”. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but instead tested for impairment at least annually in accordance with the provisions of FASB ASC 350. FASB ASC 350 also requires that intangible assets with definite useful lives be amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment in accordance with FASB ASC 360.

(g) Impairment or Disposal of Long-Lived Assets

The Company reviews its long-lived assets for impairment in accordance with FASB ASC 360 whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds fair value. Assets to be disposed of would be separately presented on the balance sheet and reported at the lower of their carrying amount or fair value less costs to sell, and no longer depreciated.

(h) Revenue Recognition

The Company generates revenue primarily by delivering performance-based advertising services, which include call advertising, cost-per-action services, and pay-per-click services. These primary sources amounted to greater than 77% of revenue for the years ended December 31, 2013, 2014 and 2015. In addition, the Company generates revenue through its Local Leads platform, which enables partner resellers to sell call advertising and/or search marketing products, and campaign management services. These secondary sources accounted for less than 23% of revenue for the years ended December 31, 2013, 2014 and 2015.

The Company recognizes revenue upon the completion of its performance obligation, provided that: (1) evidence of an arrangement exists; (2) the arrangement fee is fixed and determinable; and (3) collection is reasonably assured. The Company has no barter transactions.

In providing pay-for call marketing services, 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 phone call, which occurs when a user makes a phone call or clicks on any of their advertisement listings after it has been placed by the Company or by the Company’s distribution partners. Each phone call on an advertisement listing represents a completed transaction. The advertisement listings are displayed within the Company’s distribution network, which includes mobile and online search engines and applications, directories, destination sites, shopping engines, third party Internet domains or web sites, and other targeted Web-based content, mobile carriers and offline sources. 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.

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 or call related data element they receive from calls including call-based ads the Company distributes through our sources of call distribution or for each phone number tracked based on a pre-negotiated rate.

The Company generates revenue from reseller partners and publishers utilizing the Company’s Local Leads platform to sell call advertising, search marketing, and other lead generation products. The Company is paid account fees and also agency fees for the Company’s products in the form of a percentage of the cost of every call or click delivered to advertisers. The reseller partners or publishers engage the advertisers and are the primary obligor, 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 primary obligor. The Company recognizes revenue for these fees under the gross revenue recognition method.

Advertisers pay the Company additional fees for services such as campaign management. Advertisers generally pay the Company on a click-through basis, although in certain cases the Company receives a fixed fee for delivery of these services. In some cases we also deliver banner campaigns for select advertisers. Banner advertising revenue may be based on a fixed fee per click and is generated and recognized on click-through activity. In other cases, banner payment terms are volume-based with revenue generated and recognized when impressions are delivered.

The Company’s revenues are primarily generated using third party distribution networks to deliver the pay-for-call and pay-per-click advertisers’ listings. The distribution network includes mobile and online search engines and applications, directories, destination sites, shopping engines, third party Internet domains or web sites, other targeted Web-based content, mobile carriers and other offline sources. The Company enters into agreements with various distribution partners to provide distribution for pay-for-call and pay-per-click advertisement listings, which contain call tracking numbers and/or URL strings of its advertisers. The Company pays a revenue share to the distribution partners to access their mobile, online, offline and other user traffic. The Company generally pays distribution partners based on a percentage of revenue or a fixed amount per phone call or click-through on these listings. The Company acts as the primary obligor with the advertiser for revenue call or click-through transactions, and is responsible for the fulfillment of services.

The revenue derived from advertisers is generally reported gross based upon the amounts received from the advertiser. The Company also recognizes revenue for certain agency contracts with advertisers under the net revenue recognition method. Under these specific agreements, the Company purchases listings on behalf of advertisers from mobile sources, search engines and applications, directories, other Web-based content providers and offline sources. The Company is paid account fees and also agency fees based on the total amount of the purchase made on behalf of these advertisers. Under these agreements, the advertisers are primarily responsible for choosing the publisher and determining pricing, and the Company, in certain instances, is only financially liable to the publisher for the amount collected from our advertisers. This creates a sequential liability for media purchases made on behalf of advertisers. In certain instances, the web publishers engage the advertisers directly and the Company is paid an agency fee based on the total amount of the purchase made by the advertiser. In other arrangements resellers pay us a fee for fulfilling an advertiser’s campaign in our distribution network and we act as the primary obligor. We recognize revenue for these fees under the gross revenue recognition method.

For arrangements that include multiple deliverables, the entire fee from the arrangement is allocated to each respective deliverable based on its relative selling price and recognized when revenue recognition criteria for each deliverable are met. The selling price for each deliverable is established based on the sales price charged when the same deliverable is sold separately, the price at which a third party sells the same or similar and largely interchangeable deliverable on a standalone basis or the estimated selling price if the deliverable were to be sold separately.

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 the end of a reporting period.

(i) Service Costs

The largest component of the Company’s service costs consist of user acquisition costs that relate primarily to payments made to distribution partners for access to their mobile, online, and other offline user traffic. The Company enters into agreements of varying durations with distribution partners that integrate the Company’s services into their web sites and indexes. The primary payment structure of the distribution partner agreements is a variable payment based on a specified percentage of revenue. These variable payments are often subject to minimum payment amounts per phone call. Other payment structures that to a lesser degree exist include: 1) variable payments based on a specified metric, such as number of paid calls or other actions, 2) fixed payments, based on a guaranteed minimum amount of usage delivered, and 3) a combination arrangement with both fixed and variable amounts that may be paid in advance.

The Company expenses user acquisition costs based on whether the agreement provides for variable or fixed payments. Agreements with variable payments based on a percentage of revenue, number of paid phone calls or other metrics are expensed as incurred based on the volume of the underlying activity or revenue multiplied by the agreed-upon price or rate. Agreements with fixed payments with minimum guaranteed amounts of usage are expensed as the greater of the pro-rata amount over the term of arrangement or the actual usage delivered to date based on the contractual revenue share.

Service costs also include network operations and customer service costs that consist primarily of costs associated with providing performance-based advertising and marketing services, network costs and fees paid to outside service providers that provide the Company’s paid listings and customer services. Customer service and other costs associated with serving the Company’s call marketing services include depreciation and colocation charges of network equipment, bandwidth and software license fees, salaries of related personnel, stock-based compensation and telecommunication costs, including the use of telephone numbers for providing call-based advertising services. Other service costs include credit card processing fees and domain name and related costs, including the renewal of the domain name registrations.

(j) Advertising Expenses

Advertising costs are expensed as incurred and include mobile and online advertising and related outside marketing activities, including sponsorships and trade shows. Such costs are included in sales and marketing. Advertising costs were approximately $1.0 million, $742,000 and $2.4 million for the years ended December 31, 2013, 2014 and 2015, respectively.

(k) Product Development and Other Intangible Assets

Product development costs consist primarily of expenses incurred by the Company in the research and development, creation, and enhancement of the Company’s call services and websites. Research and development costs are expensed as incurred and include compensation and related expenses, costs of computer hardware and software, and costs incurred in developing features and functionality of the services. For the periods presented, substantially all of the product development expenses are research and development. Product development costs are expensed as incurred or capitalized into property and equipment in accordance with FASB ASC 350. FASB ASC 350 requires that cost incurred in the preliminary project and post-implementation stages of an internal use software project be expensed as incurred and that certain costs incurred in the application development stage of a project be capitalized.

The Company capitalizes costs incurred to acquire domain names or URLs, which include the initial registration fees, and amortizes the costs over the expected useful life of the domain names on a straight-line basis. The expected useful lives range from 12 to 36 months. In order to maintain the rights to each domain name acquired, the Company pays periodic registration fees, which generally cover a minimum period of 12 months. The Company records registration renewal fees of domain name intangible assets as a prepaid expense and recognizes the cost over the renewal period.

(l) Income Taxes

We utilize the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax law is recognized in results of operations in the period that includes the enactment date. In 2014, we adopted ASU 2013-11 whereby we reclassified uncertain tax positions of $534,000 from other non-current liabilities to deferred tax assets.

(m) Stock-Based Compensation

(n) Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America 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, the fair value of the Company’s common stock and stock option awards, the impairment of goodwill and intangible assets and the valuation allowance for deferred tax assets. Actual results could differ from those estimates.

(o) Concentrations

The Company maintains substantially all of its cash and cash equivalents with one financial institution and are all considered at Level 1 fair value with observable inputs that reflect quoted prices for identical assets or liabilities in active markets. At various points during the year ended December 31, 2015, the Company held cash equivalents in a commercial paper sweep account with the same financial institution. These Level 2 assets were fully liquidated prior to December 31, 2015.

A significant majority 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 consolidated revenue for the year ended December 31, 2015. There was one distribution partner who was paid less than 17% of consolidated revenue for each of the years ended December 31, 2013 and 2014.

The advertisers representing more than 10% of consolidated revenue are as follows (in percentages):


	Years ended December 31,
	2013			2014			2015
Advertiser A		26	%		25	%		29	%
Advertiser B		13	%			*			*
Advertiser C		12	%		28	%			*
Advertiser D			*			*		19	%

Advertiser A is also a distribution partner.

The outstanding receivable balance for each advertiser representing more than 10% of consolidated accounts receivable is as follows (in percentages):


	At December 31,
	2014			2015
Advertiser A		41	%		14	%
Advertiser D		16	%		28	%
Advertiser E			*		19	%

*	Less than 10%.

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. For the years ended December 31, 2013 and 2014 no advertising agency represented more than 10% of consolidated revenue and for the year ended December 31, 2015, one advertising agency represented 18% of consolidated revenue. As of December 31, 2013, no advertising agency represented more than 10% of consolidated accounts receivable. There was one advertising agency, which represented 13% and 22% of consolidated accounts receivable balance as of December 31, 2014 and December 31, 2015, respectively.

(p) 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 our 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. Additionally, the Company has paid dividends equally to both classes of common stock and the unvested restricted shares since it initiated a quarterly cash dividend in November 2006.

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. Under the two class method, dividends paid on unvested restricted stock are allocated to these participating securities and therefore impact the calculation of amounts allocated to common stock.

The following table calculates net income (loss) from continuing operations to net income (loss) applicable to common stockholders used to compute basic net income (loss) per share for the periods ended (in thousands, except per share amounts):

For the years ended December 31, 2013, 2014, and 2015, 174, 1,007, and 785 shares of unvested Class B restricted common shares, respectively.

•

For the year ended December 31, 2013, 2014 and 2015, 43, 1,134, and 1,437 restricted stock units, respectively.

(q) Guarantees

FASB ASC 460 provides accounting guidance surrounding liability recognition and disclosure requirements related to guarantees. In the ordinary course of business, the Company is not subject to potential obligations under guarantees that fall within the scope of FASB ASC 460 except for standard indemnification provisions that are contained within many of the Company’s advertiser and distribution partner agreements, and give rise only to the disclosure requirements prescribed by FASB ASC 460.

In certain agreements, 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 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.

(r) Recent Accounting Pronouncement Not Yet Effective

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09), which amends the existing accounting standards for revenue recognition. ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled when products or services are transferred to customers. In July 2015, the FASB voted to approve a one year delay of the effective date. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. ASU 2014-09 may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The Company is currently in the process of evaluating the impact of adoption of ASU 2014-09 on its consolidated financial statements.

In April 2015, the FASB issued Accounting Standards Update No. 2015-05, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40), Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement (ASU 2015-05), an ASU that provides guidance on a customer’s accounting for cloud computing costs. The ASU is effective for reporting periods beginning after December 15, 2015, with early adoption permitted. The ASU may be adopted, either retrospectively or prospectively to arrangements entered into, or materially modified, after the effective date. The Company does not expect adoption to have a material impact on its consolidated financial statements.

In November 2015, the FASB issued Accounting Standards Update No. 2015-17, Income Taxes (Topic 740), Balance Sheet Classification of Deferred Taxes (ASU 2015-17), an ASU amending the accounting for income taxes and requiring all deferred tax assets and liabilities to be classified as non-current on the consolidated balance sheet. The ASU is effective for reporting periods beginning after December 15, 2016, with early adoption permitted. The ASU may be adopted either prospectively or retrospectively. The Company does not expect adoption to have a material impact on its consolidated financial statements.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842), an ASU requiring the recognition of lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The ASU is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The ASU must be adopted retrospectively. The Company is currently in the process of evaluating the impact of adoption of ASU 2016-02 on its consolidated financial statements.

Credit Agreement

(3) Credit Agreement

In April 2008, the Company entered into a credit agreement providing for a senior secured $30 million revolving credit facility (“Credit Agreement”). The Credit Agreement, as amended, matures on April 1, 2017. Interest on outstanding balances under the Credit Agreement will accrue at LIBOR plus an applicable margin rate, as determined under the agreement and has an unused commitment fee.

Commitments and Contingencies

(4) Commitments and Contingencies

(a) Commitments

The Company has commitments for future payments related to office facilities leases and other contractual obligations. The Company leases its office facilities under operating lease agreements expiring through 2018. The Company recognizes rent expense under such agreements on a straight-line basis over the lease term with any lease incentive amortized as a reduction of rent expense over the lease term. The Company also has other contractual obligations expiring over varying time periods through 2018. Other contractual obligations primarily relate to minimum contractual payments due to distribution partners and other outside service providers.

Future minimum payments are approximately as follows (in thousands):


	Facilities operating leases		Other contractual obligations		Total
2016	$	2,319	$	3,904	$	6,223

Rent expense incurred by the Company was approximately $1.9 million for each of the years ended December 31, 2013, 2014 and 2015.

(b) Contingencies

On November 17, 2015, Steven Porter, a purported shareholder of the Company, filed a securities class action against the Company and certain officers of the Company, alleging violations of the federal securities laws (the “Complaint”). Mr. Porter seeks to represent all people who purchased or otherwise acquired the Company’s Class B common stock during the period from March 19, 2014 to September 18, 2014, and seeks unspecified damages. The Complaint alleges securities violations, and that false and/or misleading statements were made and that the material adverse facts about the Company’s business, operations, and prospects failed to be disclosed. The Company intends to vigorously defend itself against the claims asserted in this action and believes that it has meritorious defenses to the allegations made in the Complaint.

In addition, 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 to, 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 believes the legal proceedings and other claims mentioned above, based on current knowledge, will not have a material adverse effect on the Company’s financial condition, results of operations or liquidity.

Net deferred tax assets	$	—		$	—

As of December 31, 2015, the Company’s federal NOL carryforwards were approximately $40.0 million for income tax purposes, which will begin to expire in 2026. As of December 31, 2015, the Company’s state, city, and other foreign jurisdiction NOL carryforwards were approximately $6.2 million, which begin to expire in 2025.

In addition, at December 31, 2014 and 2015, the Company had certain federal NOL carryforwards of approximately $1.7 million, which begin to expire in 2019. The Tax Reform Act of 1986 limits the use of NOL and tax credit carryforwards in certain situations where changes occur in the stock ownership of a company. The Company believes that such a change has occurred related to these specific NOL carryforwards, and that the utilization of the approximately $1.7 million in carryforwards is limited such that substantially all of these NOL carryforwards will never be utilized. Accordingly, the Company has not included these federal NOL carryforwards in its deferred tax assets.

As of December 31, 2015, the Company has research and development credit carryforwards of $4.0 million available for income tax purposes, which will begin to expire 2029. In December 2015, the Protecting Americans from Tax Hikes (Path) Act of 2015 was signed into law and retroactively extended the research and development tax credit to January 1, 2015 through December 31, 2015 and prospectively made the credit permanent. Accordingly, a tax benefit of $510,000 was included in the year ended December 31, 2015. In December 2014, the Tax Increase Prevention Act of 2014 was signed into law and retroactively extended the research and development tax credit to January 1, 2014 through December 31, 2014. Accordingly, a tax benefit of $547,000 was included in the year ended December 31, 2014.

The Company has recorded a deferred tax asset for stock-based compensation recorded on unexercised non-qualified stock options and certain restricted shares and restricted share units. The ultimate realization of this asset is dependent upon the fair value of the Company’s stock when the options are exercised and when restricted shares or restricted share units vest, and generation of sufficient taxable income to realize the benefit of the related tax deduction.

At December 31, 2013 , 2014 and 2015, the Company recorded a valuation allowance of $23.0 million, $44.8 million and $34.5 million, respectively, against its federal, state, city and foreign net deferred tax assets, as it believes it is more likely than not that these benefits will not be realized. The net change in the total valuation allowance for each of the years ended December 31, 2014 and 2015 was an increase of $21.8 million and a decrease of ($10.3) million, respectively. During 2015, the Company’s deferred tax assets and valuation allowance decreased $10.3 million primarily due to the April 2015 sale of certain assets related to Archeo’s domain operations, including the bulk of its domain portfolio.

The Company regularly reviews deferred tax assets to assess whether it is more likely than not that the deferred tax assets will be realized and, if necessary, establishes a valuation allowance for portions of such assets to reduce the carrying value. 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 Company incurred taxable losses in 2013, 2014, and 2015 of $7.6 million, $10.9 million, and $13.6 million, respectively. During the third quarter of 2014, a significant customer cancelled its arrangement with the Company resulting in lower projected revenue and profitability. 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.

During the years ended December 31, 2013, 2014 and 2015, the Company recognized excess tax benefits (shortfalls) on stock option exercises, restricted stock vesting, and dividends paid on unvested restricted stock of approximately ($76,000), ($1.2) million, and $0, respectively, which were recorded to additional paid-in capital.

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 our 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 following table summarizes activity related to tax contingencies from January 1, 2013 to December 31, 2015 (in thousands):

Stockholders' Equity

(6) Stockholders’ Equity

(a) Common Stock and Authorized Capital

The authorized capital stock of the Company consists of 1,000,000 shares of undesignated preferred stock and 125,000,000 shares of Class B common stock. The Company’s board of directors has the authority to issue up to 1,000,000 shares of preferred stock, $0.01 par value in one or more series and has the authority to designate rights, privileges and restrictions of each such series, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series.

The Company has two classes of authorized common stock: Class A common stock and Class B common stock. Except with respect to voting rights, the Class A and Class B shares have identical rights. Each share of Class A common stock is entitled to twenty-five votes per share, and each share of Class B common stock is entitled to one vote per share. Each share of Class A common stock is convertible at the holder’s option into one share of Class B common stock.

In accordance with the stockholders’ agreement signed by Class A and the founding Class B common stockholders, the following provisions survived the Company’s initial public offering: Class A stockholders other than Russell C. Horowitz may only sell, assign or transfer their Class A stock to existing Class A stockholders or to the Company and in the event of transfers of Class A stock not expressly permitted by the stockholders’ agreement, such shares of Class A stock shall be converted into shares of Class B common stock.

In April 2014, the Company completed a follow-on public offering in which the Company sold an aggregate of 3.4 million shares of the Company’s Class B common stock, which includes the exercise of the underwriters’ option to purchase 514,100 additional shares, at a public offering price of $10.50 per share. In addition, another 3.2 million shares were sold by the selling stockholders, which include the exercise of the underwriter’s option to purchase 343,000 additional shares. The Company received aggregate net proceeds of $32.5 million, after deducting underwriting discounts and commissions and estimated offering expenses. The Company did not receive any of the proceeds from the sales of shares by the selling stockholders.

In November 2014, the Company’s board of directors authorized a new 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 years ended December 31, 2014 and 2015, the Company repurchased 669,000 and 924,000 shares of Class B common stock for $2.5 million and $3.8 million, respectively, as part of the 2014 Repurchase Program. During the year ended December 31, 2013, the Company repurchased approximately 31,000 shares of Class B common stock for $119,000 under its previous repurchase program.

During the years ended December 31, 2013, 2014 and 2015, the Company’s board of directors authorized the retirement of 679,000 shares, 598,000 shares, and 1,375,000 shares, respectively, of the Company’s Class B common stock, all of which have been repurchased by the Company. Shares repurchased but not yet retired by the Company are classified as treasury stock on the consolidated balance sheet before retirement. Retirement of treasury stock results in reductions to common stock and additional paid-in capital.

The Company’s board of directors declared the following quarterly dividends on the Company’s Class A common stock and Class B common stock:


Approval Date	Per share dividend		Date of record	Total amount (in thousands)		Payment date
January 2014	$	0.02	February 7, 2014	$	771	February 18, 2014
April 2014	$	0.02	May 5, 2014	$	846	May 15, 2014
July 2014	$	0.02	August 5, 2014	$	856	August 15, 2014
October 2014	$	0.02	November 7, 2014	$	857	November 18, 2014
January 2015	$	0.02	February 6, 2015	$	840	February 17, 2015
April 2015	$	0.02	May 7, 2015	$	845	May 18, 2015

We do not anticipate declaring or paying further dividends subsequent to the May 2015 dividend in the foreseeable future

(b) Stock Option Plan

The Company’s stock incentive plan (the “2012 Plan”), which was established in 2012, allows for grants of stock options, restricted stock units and restricted stock awards to eligible participants and such options may be designated as incentive or non-qualified stock options at the discretion of the 2012 Plan’s Administrative Committee. Prior to the 2012 Plan, the Company granted stock-based awards under its 2003 Amended and Restated Stock Incentive Plan (the “2003 Plan”). No further awards were made under the 2003 Plan after December 31, 2012. The 2012 Plan authorizes up to 3,500,000 shares of Class B common stock that may be issued with respect to awards granted under the 2012 Plan, and provides that the total number of shares of Class B common stock for which options designated as incentive stock options may be granted shall not exceed 3,500,000 shares. Annual increases to each of these share limits are to be added on the first day of each fiscal year beginning on January 1, 2013 equal to 5% of the outstanding common stock (including for this purpose any shares of common stock issuable upon conversion of any outstanding capital stock of the Company) or in the case of incentive stock options, the lesser of 2,000,000 shares of Class B common stock or such number as determined by the Company’s board of directors. As a result of this provision, the authorized number of shares available under the 2012 Plan was increased by 2,102,493 and 2,097,153 on January 1, 2015 and 2016, respectively, bringing the aggregate authorized number of shares available under the 2012 plan to 11,501,545. The Company may issue new shares or reissue treasury shares for stock option exercises and restricted stock grants. Generally, stock options have 10-year terms and vest 25% each year either annually or quarterly, over a 4-year period and restricted stock awards and units vest 25% each year annually over a 4-year period.

The Company did not grant any options with exercise prices less than the then current market value during 2013, 2014, and 2015.

The Company measures stock-based compensation cost at the grant date based on the fair value of the award and recognizes it as expense, net of estimated forfeitures, over the vesting or service period, as applicable, of the stock award using the straight-line method. Stock-based compensation has been included in the same lines as compensation paid to the same employees in the consolidated statements of operations.

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


	Twelve months ended December 31,
	2013		2014		2015
Service costs	$	1,179	$	1,373	$	1,189
Sales and marketing		643		888		1,307
Product development		1,635		2,595		2,410
General and administrative		5,777		7,032		5,118

Total stock-based compensation	$	9,234	$	11,888	$	10,024

For the years ended December 31, 2013, 2014, and 2015, the income tax benefit related to stock-based compensation included in net loss from continuing operations was $2.6 million, $0, and $0, respectively.

FASB ASC 718 requires the benefits of tax deductions in excess of the stock-based compensation cost to be classified as financing cash inflows and is shown as “Excess tax benefit related to stock-based compensation” on the consolidated statement of cash flows. In addition, a tax benefit and a credit to additional paid-in capital for the excess deductions is not recognized until that deduction reduces taxes payable. For the years ended December 31, 2013, 2014 and 2015, we incurred excess tax benefits of $3.0 million, $6.6 million and $331,000, respectively, which were not recorded because the Company is in a cumulative loss carryforward position for income taxes.

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 years ended December 31, 2013, 2014 and 2015, 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 forfeitures. 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 Company uses an expected annual dividend yield in consideration of the Company’s common stock dividend payments.

The following weighted average assumptions were used in determining the fair value of time-vested stock options granted for the periods indicated:


	Years ended December 31,
	2013	2014	2015
Expected life (in years)	4.00 – 6.25	4.00	4.00 – 6.25
Risk-free interest rate	0.57% to 2.10%	1.25% to 1.45%	1.13% to 1.56%
Expected volatility	54% to 64%	55% to 62%	59% to 65%
Weighted average expected volatility	57%	56%	62%
Expected dividend yield	0.87% to 2.33%	0.76% to 2.03%	0.00% to 0.36%

The Company may issue equity awards which include stock options and restricted stock awards that have vesting based on a combination of certain service and market conditions. The compensation costs and derived service periods for stock option grants with vesting based on a combination of service and market conditions are estimated using the binomial lattice model to determine the fair value for each tranche and a Monte Carlo simulation to determine the derived service period for each tranche. The risk-free interest rate is based on the 10 year bond rate as of the valuation date based on the contractual life of the option.

The following weighted average assumptions were used in determining the fair value for options granted with vesting based on a combination of certain service and market conditions for the period indicated:


		2013
Expected life (in years)		1.18 – 2.28
Risk-free interest rate		2.89%
Expected volatility		61%
Weighted average expected volatility		61%
Expected dividend yield		0.89%

There were no awards granted in 2014 or 2015 with vesting based on a combination of certain service and market conditions.

Stock option, restricted stock award, and restricted stock unit activity during the period is as follows:


	Options and Restricted Stock available for grant			Number of options outstanding			Weighted average exercise price of options		Weighted average remaining contractual term (in years)		Aggregate intrinsic value (in thousands)
Balance at December 31, 2014		2,207,633			7,797,228		$	7.90		6.58	$	800

Options exercisable at December 31, 2015					5,686,583		$	7.77		5.01	$	41

Information related to stock compensation activity during the period indicated is as follows:


	Years ended December 31,
	2013		2014		2015
Weighted average fair value of options granted	$	2.56	$	3.89	$	2.13

Total grant date fair value of restricted stock vested (in thousands)	$	5,751	$	6,568	$	7,657

At December 31, 2015, there was $7.2 million of unrecognized stock option compensation expense related to non-vested awards, which is expected to be recognized over a weighted average period of 2.1 years.

During the years ended December 31, 2013, 2014, and 2015 gross proceeds recognized from the exercise of stock options was $2.9 million, $4.2 million and $220,000, respectively. The net excess tax benefit (shortfall) on stock option exercises, restricted stock vesting, and dividends paid on unvested restricted stock during the years ended December 31, 2013, 2014 and 2015, of ($76,000), ($1.2) million and $0, respectively, was recorded to additional paid-in capital.

Restricted stock awards and restricted stock unit activity during the period is as follows:


	Shares/ Units			Weighted Average Grant Date Fair Value
Unvested at December 31, 2014		2,140,762		$	6.55
Granted		1,328,837			4.26
Vested		(1,025,527	)		7.47
Forfeited		(221,992	)		5.56

Unvested at December 31, 2015		2,222,080		$	4.86

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 awards and restricted stock units are accounted for under FASB ASC 718 using the straight-line method net of estimated forfeitures.

At December 31, 2015, there was $8.4 million of unrecognized restricted stock compensation expense related to non-vested restricted stock, which is expected to be recognized over a weighted average period of 2.0 years.

During 2013, 2014 and 2015, the Company repurchased 220,000, 175,000 and 70,000 shares, respectively, from certain executives for minimum withholding taxes on 1,031,000, 527,000 and 257,000 restricted stock award vests, respectively. The number of shares repurchased was based on the value on the vesting date of the restricted stock awards equivalent to the value of the executives’ minimum withholding taxes of $1.8 million, $1.1 million and $284,000 for 2013, 2014, and 2015, respectively. The Company then remitted cash to the appropriate taxing authorities. The payments are reflected as a financing activity within the consolidated statement of cash flows when paid. The payments had the effect of share repurchases by the Company as they reduced the number of shares that would have otherwise been issued on the vesting date and were recorded as a reduction of additional paid-in capital.

In February 2015, vesting of approximately 139,000 stock options and 108,000 restricted stock awards were accelerated in light of certain terms in a certain executive’s employment agreement.

(c) Employee Stock Purchase Plan

On February 15, 2004, the Company’s board of directors and stockholders approved the 2004 Employee Stock Purchase Plan (“2004 ESPP”), which became effective on March 30, 2004. The Company authorized an aggregate of 300,000 shares of Class B common stock for issuance under the plan to participating employees.

In December 2005, the compensation committee of the Company’s board of directors amended the 2004 ESPP to provide that effective January 1, 2006 eligible participants may purchase the Company’s Class B common stock under the purchase plan at a price equal to 95% of the fair value on the last day of an offering period. During the year ended December 31, 2013, 11,511 shares were purchased at prices ranging from $4.00 to $8.22 per share. The 2004 ESPP, as amended, expired on December 31, 2013.

On March 8, 2013, the Company’s board of directors adopted and in May 2013 the stockholders approved the 2014 Employee Stock Purchase Plan (“2014 ESPP”), which became effective on January 1, 2014. The Company authorized an aggregate of 225,000 shares of Class B common stock for issuance under the plan to participating employees. The 2014 ESPP provides eligible employees the opportunity to purchase the Company’s Class B common stock at a price equal to 95% of the closing price on the last business day of each purchase periods. The 2014 ESPP permits eligible employees to purchase amounts up to 15% of their compensation in the purchase period, and no employee is permitted to purchase stock worth more than $25,000 in any calendar year, valued as of the first day of each purchase period. During the year ended December 31, 2014, 11,944 shares purchased at prices ranging from $3.94 to $11.42 per share. During the year ended December 31, 2015, 27,692 shares were purchased at prices ranging from $3.70 to $4.70 per share.

(7) 401(k) Savings Plan

The Company has a Retirement/Savings Plan (401(k) Plan) under Section 401(k) of the Internal Revenue Code, which covers those employees that meet eligibility requirements. Eligible employees may contribute up to the Internal Revenue Code prescribed maximum amounts. During 2011, the Company elected to match a portion of the employee contributions up to a defined maximum. In 2013, 2014 and 2015, cash contributions were made in the amount of $186,000, $276,000 and $276,000, respectively.

Goodwill

Goodwill

(8) Goodwill

Changes in the carrying amount of goodwill during the year ended December 31, 2015 are as follows (in thousands):


	Call Driven		Archeo			Total
Balance as of December 31, 2014	$	63,305	$	2,374		$	65,679
Sale of certain assets related to domain operations		—		(2,374	)		(2,374	)

Balance as of December 31, 2015	$	63,305	$	—		$	63,305

The decrease in goodwill is related to the sale of certain assets related to Archeo’s domain operations during the second quarter of 2015, including the bulk of its domain name portfolio, and is included in the gain on sale of discontinued operations, net in the Company’s Consolidated Statements of Operations. The assets sold constituted a business within the Archeo reporting unit. Goodwill was allocated to the sold business based on its relative fair value compared to the remainder of the Archeo reporting unit at the time.

The Company reviews goodwill for impairment annually on November 30 and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. The Company performed its annual impairment testing as of November 30, 2015. As a result of the testing, the Company determined that there was no impairment of goodwill for the year ended December 31, 2015.

The estimated fair values of the Company’s reporting units were based on estimates of future operating results, discounted cash flows and other market-based factors. To calculate the estimated fair value of the Call-driven reporting unit, the Company uses the discounted cash flow method and market approach, which are weighted equally. The Company estimates discounted cash flows using estimates of future operating results and discount rates, which take into consideration factors such as estimated future revenues and operating costs, the Company’s tax rate and expectations of competitive and economic environments. The Company also uses comparative market multiples and other market-based factors. The quoted market price of the Company’s Class B common stock is used to corroborate the results of the estimates of fair values of the reporting units. However, if the Company had used materially different assumptions regarding the future performance of our reporting units or a lower market multiple in the valuation, this could have resulted in an impairment of some or all of the Company’s goodwill

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; and significant changes in competition and market dynamics. These estimates 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 or changes in the share price of the Company’s common stock and market capitalization. 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, among other factors, could result in the need to perform an impairment analysis in future periods. The Company cannot accurately predict the amount and timing of any future impairment of goodwill. Should the value of goodwill become impaired, the Company would record an impairment charge, which could have an adverse effect on its financial condition and results of operations.

The current business environment is subject to evolving market conditions and requires significant management judgment to interpret the potential impact to our assumptions. For the period January 1, 2016 to March 4, 2016, the Company’s stock price has been impacted by continued deterioration in the U.S. financial markets and at various points in time, the Company’s stock price approached or dropped below the then book value. To the extent that changes in the current business environment impact the Company’s ability to achieve levels of forecasted operating results and cash flows, if the Company’s stock price were to trade below book value per share for an extended period of time and/or should other events occur indicating the remaining carrying value of our assets might be impaired, the Company would test its goodwill for impairment and may recognize an impairment loss to the extent that the carrying amount exceeds such asset’s fair value. 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 2016.

Segment Reporting and Geographic Information

(9) 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. In July 2013, the Company sold certain assets related to Archeo’s pay-per-click advertising services and, in April 2015, the Company sold certain assets related to Archeo’s domain operations, including the bulk of its domain name portfolio. These dispositions are shown as discontinued operations, net of tax in the condensed consolidated statements of operations for all periods presented and are excluded from segment reporting. On December 31, 2015 the Company sold the remaining Archeo operations, which did not meet the criteria for discontinued operations presentation. See Note 10. Discontinued Operations and Disposition for further discussion.

The Company’s Call-driven segment comprises its performance-based advertising business focused on driving phone calls. The Archeo segment comprised the Company’s click-based advertising businesses. Call-driven segment expenses include both direct costs incurred by the segment business as well as corporate overhead costs. Archeo segment expenses only include direct costs incurred by the segment. Segment expenses exclude the following: stock-based compensation, amortization of intangible assets from acquisitions, acquisition and disposition related costs, gain on sale of Archeo assets, and other income (expense).

A measure of segment assets is not currently provided to the Company’s chief operating decision maker and has therefore not been disclosed. The carrying amount of goodwill for our Call-driven segment at December 31, 2014 and 2015 was approximately $63.3 million. The carrying amount of goodwill for our Archeo segment was approximately $2.4 million and $0 at December 31, 2014 and 2015, respectively.

Discontinued Operations and Disposition

12 Months Ended

Dec. 31, 2015

(10) Discontinued Operations and Disposition

(a) Discontinued Operations

In July 2013, the Company completed the sale of certain pay-per-click advertising services, and, in April 2015, the Company sold certain assets related to Archeo’s domain operations, including the bulk of its domain name portfolio. These disposals meet the requirements of Accounting Standards Codification 205-20, Discontinued Operations, for presentation as discontinued operations. As a result, the operating results related to these dispositions are shown as discontinued operations, net of tax. The operating results for the discontinued operations were as follows (in thousands):


	Years ended December 31,
	2013			2014		2015
Revenue	$	7,898		$	9,043	$	7,081
Expenses:
Service costs		5,992			3,322		1,624

Gain on sales and disposals of intangible assets, net		(3,774	)		—		—

Income tax expense		1,691			1,773		—

Income from discontinued operations, net of tax	$	3,049		$	3,425	$	5,123

Gain on sale of discontinued operations		1,492			422		22,195
Income tax expense		562			144		—

Gain on sale of discontinued operations, net of tax	$	930		$	278	$	22,195

Discontinued operations, net of tax	$	3,979			3,703	$	27,318

The discontinued operation incurred amortization of $190,000, $115,000 and $16,000 in the years ended December 31, 2013, 2014 and 2015, respectively.

The net cash proceeds from the sale of the pay-per-click assets in July 2013 were approximately $1.4 million, which included a contingent earn-out consideration payment in 2014. The net cash proceeds related to Archeo’s domain operations in April 2015 were approximately $28.1 million. The sale includes a contingent earn-out consideration payment that depends upon the achievement of certain thresholds and will be recognized as income when received.

(b) Disposition

On December 31, 2015, the Company sold the remaining Archeo operations for cash proceeds of $750,000. The estimated transaction costs were approximately $244,000 and the net carrying value of the liabilities assumed were approximately $990,000, resulting in a net gain of $1.5 million from the sale. The Company evaluated this disposition and determined that it did not meet the criteria for classification as a discontinued operation. As a result, operating results of these Archeo operations and the related gain on sale are reflected in the Company’s continuing operations in the consolidated statements of operations. For the years ended December 31, 2013, 2014 and 2015, income before provision for income taxes for these Archeo operations included in the Company’s continuing operations, were $4.7 million, $950,000, and $431,000, respectively.

Description of Business and Basis of Presentation

The entire disclosure related to a disposal group. Includes, but is not limited to, a discontinued operation, disposal classified as held-for-sale or disposed of by means other than sale or disposal of an individually significant component.
