Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies (a) Basis of Presentation The financial information presented in the accompanying unaudited consolidated financial statements as of June 30, 2015, and for the three and six months ended June 30, 2015 and 2014 has been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and in accordance with rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the accompanying unaudited consolidated financial statements reflect all adjustments, consisting primarily of normal recurring accruals, necessary for a fair presentation of the financial position as of June 30, 2015, the results of operations for the three and six months ended June 30, 2015 and 2014, and cash flows for the six months ended June 30, 2015 and 2014. These unaudited consolidated financial statements should be read in conjunction with the annual audited consolidated financial statements and notes thereto. (b) Reclassification Certain items in the prior period financial statements have been reclassified for comparative purposes to conform to the current period presentation. (c) Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles 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 consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates and assumptions made by management include estimated useful lives of property and equipment and capitalized software development costs, goodwill and intangibles, determination of estimated selling prices, allowances for doubtful accounts, valuation of deferred tax assets, valuation assumptions in purchase accounting, certain assumptions related to stock-based compensation and legal and other contingencies. Actual results could differ from those estimates and assumptions. (d) Cash and Cash Equivalents Highly liquid financial instruments purchased with original maturities of 90 days or less at the date of purchase are reported as cash equivalents. Cash equivalents are recorded at cost, which approximates fair value. Included in cash and cash equivalents are funds representing amounts reserved for the face value of registration fees or tickets sold on behalf of customers. While these funds are not restricted as to their use, a liability for amounts due to customers under these arrangements has been recorded in accounts payable in the accompanying consolidated balance sheets. The Company had amounts due to customers of $5.3 million and $3.4 million included within cash and cash equivalents as of June 30, 2015 and December 31, 2014, respectively. (e) Short-term Investments The Company’s short-term investments consist of highly liquid financial instruments with original maturities greater than 90 days but less than one year. These short-term investments are comprised of certificates-of-deposit. (f) Revenue Recognition The Company derives revenue from two primary sources: platform subscription-based solutions and hospitality cloud solutions. These services are generally provided under annual or multi-year contracts that are generally only cancellable for cause. Revenue is generally recognized on a straight-line basis over the life of the contract. The Company recognizes revenue when all of the following conditions are met: (i) persuasive evidence exists of an arrangement with the customer reflecting the terms and conditions under which the solutions or services will be provided; (ii) delivery to customers has occurred or services have been rendered; (iii) the fee is fixed or determinable; and (iv) collection of the fees is reasonably assured. The Company considers a signed agreement or other similar documentation to be persuasive evidence of an arrangement. Collectability is assessed based on a number of factors, including transaction history and the creditworthiness of a customer. If it is determined that collection is not reasonably assured, revenue is not recognized until collection becomes reasonably assured, which is generally upon receipt of cash. The Company applies the provisions of Financial Accounting Standards Board (“FASB”) ASU 2009-13, Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements Platform Subscription Revenue Event Management The Company generates the majority of its revenue through Software-as-a-Service (“SaaS”) subscriptions to the event management platform, pricing for which is subject to the features and functionality selected. No features or functionality within the subscription-based services have stand-alone value apart from one another and, therefore, the entire subscription fee is recognized on a straight-line basis over the term of the subscription arrangement. SaaS subscriptions may include functionality that enables customers to manage the registration of participants attending the customer’s event or events. In some cases, the negotiated fee for the subscription is based on a maximum number of event registrations permitted over the subscription term. At any time during the subscription term, customers may elect to purchase blocks of additional registrations, which are referred to as subscription up-sells. The fees associated with the up-sells are added to the original subscription fee, and the revenue is recognized over the remaining subscription period. No portion of the subscription fee is refundable regardless of the actual number of registrations that occur. Mobile Apps Subscription-based solutions also include the sale of mobile event apps. The revenue for mobile event apps solutions is generally recognized on a straight-line basis over the life of the contract. A customer may use a singular mobile event app for any number of events. At any time during the subscription term, customers may elect to purchase additional mobile event apps, which are referred to as mobile up-sells. The fees associated with the up-sells are added to the original subscription fee, and the revenue is recognized over the remaining subscription period. No portion of the subscription fee is refundable. Audience Management Platform Revenue related to the Audience Management Platform is generated primarily through convenience and order processing fees charged to the end user purchasing tickets at the time a ticket for an event is sold and is recorded at the time of the event, net of the face value of the ticket. Revenue for these ticket fees collected in advance of the event is recorded as deferred revenue until the event occurs. If an event is cancelled, the customer receives a full refund of the ticket price and fees paid. Other subscription-based solutions include the sale of survey solutions, which are contracted though annual or multiyear arrangements. Subscription agreements do not provide customers with the right to take possession of the underlying software at any time. Hospitality Cloud Revenue In 2014, the Hospitality Cloud was branded to provide a full spectrum of cloud-based solutions across the hotel group sales lifecycle. Prior to this branding, the Company primarily concentrated on servicing the hospitality sector with marketing solutions through the Cvent Supplier Network (“CSN”), which continues to provide substantially all of the revenue for this product line as it did in the prior periods. Marketing solutions revenue is generated through the delivery of various forms of advertising sold through annual or multi-year contracts to marketers, principally hotels and venues. Such solutions include prominent display of a customer’s venue within CSN, the Cvent Destination Guide, the Elite Meetings magazine or additional sourcing websites such as EliteMeetings.com and SpeedRFP.com, each of which are designed for a different planner audience. Pricing for the advertisements is based on the term of the advertisement, targeted geography, number of advertisements and prominence of the ad placement. The Company enters into arrangements with multiple deliverables that generally include various marketing solutions that may be sold individually or bundled together and delivered over various periods of time. In such situations, the Company applies the provisions of FASB, Accounting Standards Codification (“ASC”), No. 605-25, Revenue Recognition – Multiple Element Arrangements Certain one-time marketing solutions, which can run for a month, several months, or a year, are primarily sold in a package. In determining whether the marketing solutions sold in packages have standalone value, the Company considers the availability of the services from other vendors, the nature of the solutions, and the contractual dependence of the solutions to the rest of the package. Based on these considerations, the Company has determined the estimated selling price for each marketing solution sold in a package. Revenue arrangements with multiple deliverables are divided into separate units of accounting and the arrangement consideration is allocated to all deliverables based on the relative selling price method. In such circumstances, the Company uses the selling price hierarchy of: (i) Vendor-specific objective evidence, or VSOE, if available, (ii) third-party evidence of selling price, or TPE, and (iii) best estimate of selling price. VSOE is limited to the price charged when the same element is sold separately by the Company. Due to the unique nature of some multiple deliverable revenue arrangements, the Company may not be able to establish selling prices based on historical stand-alone sales using VSOE or TPE; therefore the Company may use its best estimate to establish selling prices for these arrangements. The Company establishes the best estimates within a range of selling prices considering multiple factors including, but not limited to, size of transaction, customer demand and price lists. (g) Deferred Revenue Deferred revenue consists of contractual billings or payments received in advance of revenue recognition from platform subscription services or Hospitality Cloud solutions that are subsequently recognized when the revenue recognition criteria are met. The Company generally invoices customers in advance in annual or quarterly installments. (h) Business Combinations The Company is required to allocate the purchase price of acquired companies to the identifiable tangible and intangible assets acquired and liabilities assumed at the acquisition date based upon their estimated fair values. Goodwill as of the acquisition date represents the excess of the purchase consideration of an acquired business over the fair value of the underlying net tangible and intangible assets acquired and liabilities assumed. This allocation and valuation require management to make significant estimates and assumptions, specifically with respect to the value of long-lived and intangible assets. Critical estimates in valuing intangible assets include but are not limited to estimates about: future expected cash flows from customer contracts, customer lists, distribution agreements, proprietary technology and non-competition agreements; the acquired company’s brand awareness and market position, assumptions about the period of time the brand will continue to be used in the Company’s product portfolio; as well as expected costs to develop the in-process research and development into commercially viable products and estimated cash flows from the projects when completed, and discount rates. The Company’s estimates of fair value are based upon assumptions the Company believes to be reasonable, but which are inherently uncertain and unpredictable. Assumptions may be incomplete or inaccurate, and unanticipated events and circumstances may occur. In addition, uncertain tax positions and tax-related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date. The Company continues to evaluate these items quarterly and records any adjustments to the preliminary estimates to goodwill provided that the Company is within the measurement period. Subsequent to the measurement period, changes to these uncertain tax positions and tax related valuation allowances will affect the Company’s provision for income taxes in the consolidated statements of operations in the current period. Other estimates associated with the accounting for these acquisitions may change as additional information becomes available regarding the assets acquired and liabilities assumed. Costs incurred related to acquisitions are expensed as incurred. (i) Goodwill Goodwill represents the excess of: (i) the aggregate of the fair value of consideration transferred in a business combination, over (ii) the fair value of assets acquired, net of liabilities assumed. Goodwill is not amortized, but is subject to annual impairment tests. The goodwill impairment test is a two-step test. Under the first step, the fair value of the reporting unit is compared with its carrying value, including goodwill. If the fair value of the reporting unit is less than its carrying value, an indication of goodwill impairment exists for the reporting unit and the entity must perform step two of the impairment test (measurement). Under step two, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation and the residual fair value after this allocation is the implied fair value of the reporting unit goodwill. Fair value of the reporting unit is estimated using a discounted cash flow analysis. If the fair value of the reporting unit exceeds its carrying value, step two is not performed. In September 2011, the FASB issued ASU 2011-08, Intangibles—Goodwill and Other (Topic 350): Testing Goodwill for Impairment The Company performs its annual impairment review of goodwill on November 30 and when a triggering event occurs between annual impairment tests. There were no triggering events or indications of impairment as of June 30, 2015. (j) Capitalized Software Development Costs Costs to develop internal use software to support the Company’s platform are capitalized and recorded as capitalized software in accordance with the provisions of FASB ASC Subtopic 350-40, Intangibles-Goodwill and Other Subtopic 40 Internal-Use Software (k) Deferred Tax Assets and Liabilities Income taxes are accounted for under the asset and liability 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 rates is recognized in income in the period that includes the enactment date. To the extent that it is not considered to be more likely than not that a deferred tax asset will be realized, a valuation allowance is established. The Company applies the provisions of FASB interpretation No. 48, Accounting for Uncertainty in Income Taxes Income Taxes—Overall (l) Stock-Based Compensation The Company accounts for its employee stock-based compensation awards in accordance with FASB ASC Topic 718, Compensation—Stock Compensation Determining the fair value of stock options under the Black-Scholes model requires judgment, including estimated volatility, risk free rate, expected term and estimated dividend yield. The assumptions used in calculating the fair value of stock-based compensation awards represent the Company’s best estimates, based on management judgment. The estimate of the value per share of the Company’s common stock used in the option-pricing model prior to the Company’s IPO in August 2013 was based on the contemporaneous valuations performed with the assistance of an unrelated third-party valuation specialist and management’s analysis of market transactions in proximity to the valuation dates. The estimated dividend yield is zero since the Company has not issued dividends to date and does not anticipate issuing dividends. The risk-free interest rate is based on the implied yield currently available on U.S. Treasury zero coupon issues with an equivalent remaining term. Due to its limited trading history, the Company estimates volatility for option grants by evaluating the average historical volatility of a peer group of similar public companies. The expected term of the Company’s stock options represent the period that its stock-based awards are expected to be outstanding. For purposes of determining the expected term, the Company applies the simplified approach, in which the expected term of an award is presumed to be the mid-point between the vesting date and the expiration date of the award. Awards generally vest over a service period of four years, with a maximum contractual term of ten years. Pursuant to FASB ASC Subtopic 718-10-35, Stock Compensation (m) Foreign Currency The Company’s foreign subsidiary in India designates the U.S. dollar as the functional currency. For the subsidiary, assets and liabilities denominated in foreign currency are remeasured into U.S. dollars at current exchange rates for monetary assets and liabilities and historical exchange rates for nonmonetary assets and liabilities. Foreign currency gains and losses associated with remeasurement are included in general and administrative expense in the consolidated statements of operations. Foreign currency gains (losses) associated with transactions and remeasurement were $(1.0) million and less than $0.1 million for the three months ended June 30, 2015 and 2014, respectively; and $(0.8) million and $0.5 million for the six months ended June 30, 2015 and 2014, respectively. The Company’s foreign subsidiary in the UK designates the British Pound as its functional currency. For the subsidiary, assets and liabilities denominated in foreign currency are translated into U.S. dollars at current exchange rates. Foreign currency gains and losses associated with translation are included in accumulated other comprehensive gain (loss) in the consolidated balance sheets. (n) Non-Monetary Transactions The Company occasionally participates in non-monetary transactions with its customers in exchange for marketing and other services.
