Basis of Presentation and Consolidation

The accompanying unaudited condensed consolidated financial statements and condensed footnotes have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by United States generally accepted accounting principles (“GAAP”) for complete financial statements. In the opinion of management, all adjustments, consisting of only normal recurring items, considered necessary for fair statement have been included. The results of operations for the three months ended March 31, 2016, are not necessarily indicative of the results to be expected for the year ending December 31, 2016, or for other interim periods or for future years.

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated on consolidation. The condensed consolidated balance sheet as of December 31, 2015, is derived from audited financial statements as of that date but does not include all of the information and footnotes required by GAAP for complete financial statements.

These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 filed with the Securities and Exchange Commission (“SEC”) on February 22, 2016.

Fair Value Measurements

The Company’s financial instruments, including cash equivalents, accounts receivable, accounts payable and accrued expenses are carried at cost, which approximates fair value because of the short-term nature of those instruments. Based on borrowing rates available to the Company for loans with similar terms and maturities, and in consideration of the Company’s credit risk profile, the carrying value of borrowings (Note 6) approximates fair value (level 2 within the fair value hierarchy).

Cash equivalents consist of money market funds, which are readily convertible into cash and have original maturity dates of less than three months from the date of their respective purchases. These money market funds presented as cash equivalents on the consolidated balance sheets are classified as level 1 within the fair value hierarchy, and totaled $25,587 and $25,564 as of March 31, 2016 and December 31, 2015, respectively.

Allowance for Doubtful Accounts and Revenue Credits

The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the Company’s receivables portfolio determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available evidence. The Company has not historically experienced significant credit losses from its accounts receivable. The Company performs a regular review of its customers’ payment histories and associated credit risks and it does not require collateral from its customers. Certain contracts with advertising agencies contain sequential liability provisions, whereby the agency does not have an obligation to pay the Company until payment is received from the agency’s customers. In these circumstances, the Company evaluates the credit worthiness of the agency’s customers, in addition to the agency itself. As of March 31, 2016 and December 31, 2015, the Company recorded an allowance for doubtful accounts in the amount of $2,006 and $2,188, respectively.

From time to time, the Company provides credits to customers and an allowance is made based on historical credit activity. As of March 31, 2016, and December 31, 2015, the Company recorded an allowance for potential customer credits in the amount of $1,566 and $2,274, respectively.

Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. Intangible assets that are not considered to have an indefinite useful life are amortized over their useful lives, which generally range from two to six years. Estimated remaining useful lives of purchased intangible assets are evaluated to assess whether events or changes in circumstances warrant a revision to the remaining periods of amortization.

In addition, we evaluate our goodwill for impairment at least annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that these assets may be impaired. No goodwill impairment has been identified in any of the periods presented.

Revenue Recognition

The Company generates revenues principally from subscriptions either directly with advertisers or with advertising agencies to its platform for the management of search, social and display advertising. The Company’s subscription agreements are generally one year or longer in length. The Company’s subscription fee under most contracts is variable based on the value of the advertising spend that the Company’s advertisers manage through the Company’s platform and is generally invoiced on a monthly basis. Contracts with direct advertisers and certain contracts with advertising agencies also include a minimum monthly fee that is payable over the duration of the contract. The Company’s customers do not have the right to take possession of the software supporting the application service at any time, nor do the arrangements contain general rights of return. The Company commences revenue recognition for both direct advertisers and advertising agencies when all of the following conditions are met:

persuasive evidence of an arrangement exists;

the Company’s platform is made available to the customer;

the fee is fixed or determinable; and

collection is reasonably assured.

The Company recognizes the total minimum fee for both direct advertisers and advertising agencies, where applicable, over the duration of the contract, commencing on the date that the Company’s platform is made available to the customer, provided revenues recognized do not exceed amounts that are invoiced and due. The variable fee, which is based on a percentage of the value of the advertising spend managed through the Company’s platform, is recognized once the amount is fixed or determinable, which is generally on a monthly basis concurrent with the issuance of the customer invoice. Signed contracts are used as evidence of an arrangement. The Company assesses collectability based on a number of factors such as past collection history with the customer and creditworthiness of the customer. Certain agreements with advertising agencies also contain sequential liability provisions, which provide that the agency has no obligation to pay the Company until the agency receives payment from its customers. In these circumstances, the Company evaluates the credit worthiness of the agency’s customers, in addition to the agency itself, to conclude whether or not collectability is reasonably assured. If the Company determines collectability is not reasonably assured, the Company defers the revenue recognition until collectability becomes reasonably assured.

The Company applies the authoritative accounting guidance regarding revenue recognition for arrangements with multiple deliverables. Professional services and training, when sold with the Company’s platform subscription services, are accounted for separately when those services have standalone value. In determining whether professional services and training services can be accounted for separately from subscription services, the Company considers the following factors: availability of the services from other vendors; the nature of the services; the dependence of the subscription services on the customer’s decision to buy the professional services; and whether the Company sells the Company’s subscription services without professional services. If the deliverables have stand-alone value, the Company accounts for each deliverable separately and revenues are recognized for the respective deliverables as they are delivered. If one or more of the deliverables do not have stand-alone value, the deliverables that do not have stand-alone value are combined with the final deliverables within the arrangement and treated as a single unit of accounting. Revenues for arrangements treated as a single unit of accounting are recognized over the period of the contract commencing upon delivery of the final deliverable. As of March 31, 2016, the Company did not have stand-alone value for the professional services and training services. This is because the Company includes professional services and training services with the Company’s subscription services and those services are not available from other vendors.

Cost of Revenues

Cost of revenues primarily consists of costs related to hosting the Company’s cloud-based platform, providing implementation and ongoing customer support, data communications expenses, salaries and benefits of operations and support personnel, software license fees, costs associated with website development activities, indirect overhead, amortization expense associated with capitalized internally developed software and intangible assets and property and equipment depreciation.

Recent Accounting Pronouncements

In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting (Topic 718) which is intended to simplify several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The amendments in this update are effective for annual periods beginning after December 15, 2016 and interim periods therein. Early adoption is permitted. The Company is currently evaluating the impact the adoption of this standard will have on the consolidated financial statements.

In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which updates the new revenue standard (ASU 2014-09) by clarifying the principal versus agent implementation guidance, but does not change the core principle of the new standard. The updates to the principal versus agent guidance require an entity to (1) identify the specified goods or services (or bundles of goods or services), including rights to goods or services from a third party and (2) determine whether it controls each specified good or service before each good or service (or right to a third party good or service) is transferred to the customer. This guidance will be effective for the Company in the first quarter of its fiscal year ending December 31, 2017. The Company is currently evaluating the impact of the adoption of this ASU on the consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The amendments in this update are effective for annual periods beginning after December 15, 2018 and interim periods therein, and must be adopted using a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the consolidated financial statements. The Company is currently evaluating the impact the adoption of this standard will have on the consolidated financial statements.

In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. The new standard eliminates the requirement for an acquirer to retrospectively adjust provisional amounts recorded in a business combination to reflect new information about the facts and circumstances that existed as of the acquisition date and that, if known, would have affected measurement or recognition of amounts initially recognized. As an alternative, the standard requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. It requires that the acquirer record, in the financial statements of the period in which adjustments to provisional amounts are determined, the effect on earnings of changes in depreciation, amortization or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The new standard is effective prospectively for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years, with early adoption permitted. We early adopted this standard during the first quarter of 2016 on a prospective basis, and it did not have an effect on the Company’s financial position or results of operations. We will apply the new guidance to future adjustments to provisional amounts.

In August 2014, the FASB issued ASU 2014-15, Disclosures of Uncertainties About an Entity’s Ability to Continue as a Going Concern. The new standard provides guidance around management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on the consolidated financial statements.

In June 2014, the FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. The guidance requires that a performance target that affects vesting and could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance as it relates to such awards. This guidance is effective for the Company in its first quarter of fiscal year ending December 31, 2017. The Company is currently evaluating the impact of our pending adoption of this ASU on the consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates when compared with the current guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. This guidance will be effective for the Company in the first quarter of its fiscal year ending December 31, 2017. The Company is currently evaluating the impact of the adoption of this ASU on the consolidated financial statements.
