SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The preparation of the Companys consolidated financial statements in conformity with GAAP 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 income and expenses during the reporting period. These estimates are based on information available as of the date of the consolidated financial statements; therefore, actual results could differ from managements estimates. Foreign Currency Translation The consolidated financial statements of the Companys foreign subsidiaries are measured using the local currency as the functional currency. Assets and liabilities of foreign subsidiaries are translated at exchange rates in effect as of the balance sheet date. Revenues and expenses are translated at average exchange rates in effect during the year. Translation adjustments are recorded within accumulated other comprehensive loss, a separate component of stockholders equity. Cash and Cash Equivalents The Company considers all highly liquid investments, such as treasury bills, commercial paper, certificates of deposit and money market instruments with maturities of three months or less at the time of acquisition to be cash equivalents. Cash and cash equivalents primarily consist of amounts held in interest-bearing money market funds that were readily convertible to cash. The fair value of cash and cash equivalents approximates their carrying value. Marketable Securities The Company determines the classification of its marketable securities at the time of purchase and re-evaluates these determinations at each balance sheet date. Debt securities are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity. Held-to-maturity securities are stated at amortized cost and are periodically assessed for other-than-temporary impairment. Amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity, and is included in interest income. Held-to-maturity securities with less than one year to maturity are included in short-term marketable securities. All other held-to-maturity securities are classified as long-term securities. Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company places its cash and cash equivalents with major financial institutions, which management assesses to be of high credit quality, in order to limit the exposure of each investment. Credit risk with respect to accounts receivable is dispersed due to the Companys large number of customers. In addition, the Companys credit risk is mitigated by the relatively short collection period. Collateral is not required for accounts receivable. The Company maintains an allowance for doubtful accounts receivable balances. The allowance is based upon historical loss patterns, the number of days that billings are past due and an evaluation of the potential risk of loss associated with delinquent accounts. When new information becomes available to indicate that the estimate provided for the allowance was incorrect, an adjustment, which is considered a change in the estimate, is made. The carrying value of accounts receivable approximates their fair value. As of December 31, 2016, 2015 and 2014, there were no customers that accounted for more than 10% of total accounts receivable. The following table presents the changes in the allowance for doubtful accounts (in thousands): Year Ended December 31, 2016 2015 2014 Allowance for doubtful accounts: Balance, beginning of period $ 3,208 $ 1,627 $ 810 Add: bad debt expense 15,913 10,271 6,369 Less: write-offs, net of recoveries (14,129 ) (8,690 ) (5,552 ) Balance, end of period $ 4,992 $ 3,208 $ 1,627 Property, Equipment and Software Property, equipment and software are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which are approximately three to five years. Leasehold improvements are amortized over the shorter of the lease term or 10 years. Website and Internal-Use Software Development Costs Costs related to website and internal-use software are primarily related to the Companys website, including support systems. The Company capitalizes its costs to develop software when preliminary development efforts are successfully completed, management has authorized and committed project funding and it is probable that the project will be completed and the software will be used as intended. Such costs are amortized on a straight-line basis over the estimated useful life of the related asset, which is generally three years. Costs incurred prior to meeting these criteria, together with costs incurred for training and maintenance, are expensed as incurred. Costs incurred for enhancements that are expected to result in additional material functionality are capitalized and amortized over the estimated useful life of the upgrades. The Company capitalized $19.2 million, $14.7 million and $13.9 million in website and internal-use software costs during the years ended December 31, 2016, 2015 and 2014, respectively, which are included in property, equipment and software, net on the consolidated balance sheets. Amortization expense related to website and internal-use software was $12.3 million, $8.4 million and $4.6 million for the years ended December 31, 2016, 2015 and 2014, respectively. The Company wrote off $0.1 million, $0.1 million and $0.0 million of website and internal-use software costs in the years ended December 31, 2016, 2015 and 2014, respectively. The retirements were related to obsolete projects no longer supported by the Company. The loss on disposition of the projects has been included in depreciation and amortization expense in the Companys consolidated statements of operations. Business Combinations The Company accounts for acquisitions of entities that include inputs and processes and have the ability to create outputs as business combinations. The Company allocates the purchase price of the acquisition to the tangible assets, liabilities and identifiable intangible assets acquired based on their estimated fair values. The excess of the purchase price over those fair values is recorded as goodwill. Acquisition-related expenses and integration costs are expensed as incurred. During the measurement period, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. After the measurement period, which could be up to one year after the transaction date, subsequent adjustments are recorded to the Companys consolidated statements of operations. Goodwill Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. The carrying amount of goodwill is reviewed at least annually, or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. The Company has the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of its single reporting operating unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test under the authoritative guidance issued by the Financial Accounting Standards Board (FASB). If the Company determines that it is more likely than not that its fair value is less than the carrying amount, or opts not to perform a qualitative assessment, then the two-step goodwill impairment test will be performed. The first step, identifying a potential impairment, compares the fair value of the reporting unit with its carrying amount. If the carrying amount exceeds its fair value, the second step will be performed; otherwise, no further step is required. The second step, measuring the impairment loss, compares the implied fair value of the goodwill with the carrying amount of the goodwill. Any excess of the goodwill carrying amount over the applied fair value is recognized as an impairment loss, and the carrying value of goodwill is written down to fair value. No impairment charges have been recorded to date. Intangible Assets Intangible assets include acquired intangible assets identified through business combinations, which are carried at fair value less accumulated amortization, and purchased intangible assets, which are carried at cost less accumulated amortization. Amortization is recorded over the estimated useful lives of the assets, generally two years to 12 years. The Company reviews amortizable intangible assets to be held and used for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Determination of recoverability is based on the lowest level of identifiable estimated undiscounted cash flows resulting from the use of the asset and its eventual disposition. Measurement of any impairment loss is based on the excess of the carrying value of the asset over its fair value. No impairment charges have been recorded to date. Cost-Method Investments Nonmarketable equity investments, that the Company has determined do not meet the criteria for accounting under the equity method of accounting, are accounted for using the cost method of accounting and classified as Other non-current assets on the consolidated balance sheets. Under the cost method, investments are carried at cost and are adjusted only for other-than-temporary declines in fair value, certain distributions and additional investments. The carrying amount of investments is reviewed if events or changes in circumstances indicate that the carrying value may not be recoverable. Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed of The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. Revenue Recognition The Company generates revenue from its advertising products, transactions, other services and, through the end of 2015, brand advertising. The Company recognizes revenue when all of the following conditions are met: there is persuasive evidence of an arrangement, service has been provided to the customer, the amount to be paid by the customer is fixed or determinable, and collection is reasonably assured. Payments received in advance of services being rendered are recorded as deferred revenue and recognized over the requisite service period. Advertising . The Company generates advertising revenue primarily through the display of advertising products on its website and mobile app. These arrangements are evidenced by either written or electronic acceptance of an agreement that stipulates the types of advertising to be delivered, the timing and pricing. Performance-based advertising placements are priced on a cost-per-click basis through an auction, while impression-based ads are delivered pursuant to fixed monthly fee advertising plans. The Company recognizes revenue from the delivery of performance-based ads in the period of delivery and from the delivery of impression-based ads ratably over the service period, in each case net of customer discounts. The Company also generates advertising revenue through indirect sales of advertising products, such as through reseller agreements that allow partners to sell Yelp Branded Profiles to their clients and the monetization of remnant advertising inventory through third-party ad networks. Transactions . The Company generates transactions revenue from Yelp Eat24, revenue-sharing partner arrangements and the sale of vouchers through the Companys Yelp Deals and Gift Certificates. Yelp Eat24 generates revenue through arrangements with restaurants, in which restaurants pay a commission percentage fee on orders placed through the Yelp Eat24 platform. The Company records revenue associated with Yelp Eat24 transactions on a net basis. Yelp Platform partnerships provide consumers with the ability to complete food delivery and other transactions through third parties directly on Yelp. The Company earns a fee on Platform partnerships for acting as an agent for these transactions, which it record on a net basis and include in revenue upon completion of a transaction. Yelp Deals allow merchants to promote themselves and offer discounted goods and services on a real-time basis to consumers directly on the Companys website and mobile app. The Company earns a fee on Yelp Deals for acting as an agent in these transactions, which are recorded on a net basis and included in revenue upon sale of the deal. The Company records a sales allowance for potential Yelp Deals refunds based on the Companys estimate of future refunds. Gift Certificates allow merchants to sell full-priced gift certificates directly to consumers through their business listing pages. The Company earns a fee based on the amount of the Gift Certificate sold, which it records on a net basis and includes in revenue upon a consumers purchase of the Gift Certificate. Brand Advertising. Through the end of 2015, the Company generated brand advertising revenue through the sale of graphic and text display advertisements on its website. The Company recognized revenue from the sale of impression-based advertisements on its online network in the period in which the advertisements (impressions) were delivered, net of customer discounts. The Company also generated brand revenue from fixed-price brand sponsorships that were recognized ratably over the service period. The arrangements were evidenced by insertion orders or contracts that stipulate the types of advertising delivered and the pricing. Other Services . The Company generates other revenue through subscription services, such as sales of monthly subscriptions to its Yelp Reservations product, licensing payments for access to Yelp data and other non-advertising, non-transaction partnerships. Subscription revenues are recognized ratably over the contract terms beginning on the commencement date of each contract, which is the date the service is made available to customers. Multiple Element Arrangements . The Company enters into arrangements with its customers to sell advertising packages that include different media placements or ad services that are delivered at the same time, or within close proximity of one another. The Company allocates arrangement consideration in multiple-deliverable arrangements at the inception of the arrangement to all deliverables or those packages in which all components of the package are delivered at the same time, based on the relative selling price method in accordance with the selling price hierarchy, which includes: (1) vendor-specific objective evidence (VSOE), if available; (2) third-party evidence (TPE), if VSOE is not available; and (3) best estimate of selling price (BESP), if neither VSOE nor TPE is available. VSOEThe Company determines VSOE based on its historical pricing and discounting practices for the specific product or service when sold separately. In determining VSOE, the Company requires that a substantial majority of the standalone selling prices for these services fall within a reasonably narrow price range; however, the Company has not historically sold a large volume of advertising products on a standalone basis. As a result, the Company has not been able to establish VSOE for any of its advertising products. TPEWhen VSOE cannot be established for deliverables in multiple element arrangements, the Company applies judgment with respect to whether it can establish a selling price based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, the Companys go-to-market strategy differs from that of its peers and its offerings contain a significant level of differentiation such that the comparable pricing of services cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor services selling prices are on a standalone basis. As a result, the Company has not been able to establish selling price based on TPE. BESPWhen it is unable to establish selling price using VSOE or TPE, the Company uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale if the service were sold on a standalone basis. BESP is generally used to allocate the selling price to deliverables in the Companys multiple element arrangements. The Company determines BESP for deliverables by considering multiple factors including, but not limited to, prices it charges for similar offerings, market conditions, competitive landscape and pricing practices. The Company limits the amount of allocable arrangement consideration to amounts that are fixed or determinable and that are not contingent on future performance or future deliverables. The Company will regularly review BESP. Changes in assumptions or judgments or changes to elements in the arrangement could cause a material increase or decrease in the amount of revenue that the Company reports in a particular period. The Company recognizes the relative fair value of the media placements or ad services as they are delivered assuming all other revenue recognition criteria are met. Cost of Revenue The Companys cost of revenue primarily consists of credit card processing fees, web hosting, salaries, benefits and stock-based compensation expense for its infrastructure teams related to operating the Companys website and mobile app. It also includes food delivery related costs as well as creative design for brand advertising and video production expenses. All costs are expensed when incurred. Stock-Based Compensation The Company accounts for stock-based employee compensation plans under the fair value recognition and measurement provisions in accordance with applicable accounting standards, which require all stock-based payments to employees, including grants of stock options, restricted stock awards, restricted stock units and issuances under its 2012 Employee Stock Purchase Plan, as amended (ESPP), to be measured based on the grant-date fair value of the awards. Prior to January 1, 2016, stock-based compensation expense was recorded net of estimated forfeitures in the Companys consolidated statements of income (loss) and, accordingly, was recorded for only those stock-based awards that the Company expected to vest. The Company estimated the forfeiture rate based on historical forfeitures of equity awards and adjusted the rate to reflect changes in facts and circumstances, if any. The Company revised its estimated forfeiture rate if actual forfeitures differed from its initial estimates. Effective as of January 1, 2016, the Company adopted a change in accounting policy in accordance with Accounting Standards Update 2016-09, CompensationStock Compensation (Topic 718) (ASU 2016-09) to account for forfeitures as they occur. The change was applied on a modified retrospective basis with a cumulative effect adjustment to retained earnings of $1.1 million (which reduced the accumulated deficit) as of January 1, 2016. No prior periods were recast as a result of this change in accounting policy. Advertising Expenses Advertising costs are expensed in the period in which the advertising takes place. Costs of producing advertising are expensed in the period in which production takes place. Total advertising expenses incurred were $46.9 million, $30.9 million and $8.1 million for the years ended December 31, 2016, 2015 and 2014, respectively. Comprehensive Income (Loss) Comprehensive income (loss) consists of net income (loss) and other comprehensive income (loss), which includes certain changes in equity that are excluded from net income (loss). Specifically, it includes foreign currency translation adjustments. Income Taxes The Company records income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Companys financial statements or tax returns. In estimating future tax consequences, generally all expected future events other than enactments or changes in the tax law or rates are considered. Valuation allowances are provided to reduce deferred tax assets to the amount that is more likely than not to be realized. The Company operates in various tax jurisdictions and is subject to audit by various tax authorities. The Company provides for tax contingencies whenever it is deemed probable that a tax asset has been impaired or a tax liability has been incurred for events such as tax claims or changes in tax laws. Tax contingencies are based upon their technical merits, relative tax law and the specific facts and circumstances as of each reporting period. Changes in facts and circumstances could result in material changes to the amounts recorded for such tax contingencies. The Company recognizes a tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Effective as of January 1, 2016, the Company early adopted a change in accounting policy in accordance with ASU 2016-09, which eliminated the requirement that excess tax benefits be realized as a reduction in current taxes payable before the associated tax benefit could be recognized as an increase in paid in capital. Under ASU 2016-09, these previously unrecognized deferred tax assets were recognized on a modified retrospective basis as of January 1, 2016, the start of the year in which the Company early adopted ASU 2016-09. The U.S. federal and state net operating losses and credits recognized as of January 1, 2016, as described above, have been offset by a valuation allowance. As a result, only the Ireland net operating losses resulted in a cumulative-effect adjustment to retained earnings of $0.2 million (which reduced the accumulated deficit) as of January 1, 2016. Additionally, ASU 2016-09 addresses the presentation of excess tax benefits and employee taxes paid on the statement of cash flows. The Company is now required to present excess tax benefits as an operating activity in the same manner as other cash flows related to income taxes on the statement of cash flows rather than as a financing activity. The Company adopted this change prospectively. Employee Benefit Plan The Company sponsors a qualified 401(k) defined contribution plan covering eligible employees. Participants may contribute a portion of their annual compensation up to a maximum annual amount set by the Internal Revenue Service (IRS). Employer contributions under this plan were $3.8 million, $2.9 million and $1.9 million for the years ended December 31, 2016, 2015 and 2014, respectively. Recent Accounting Pronouncements Not Yet Effective In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014-09 “Revenue from Contracts with Customers” (“ASU 2014-09”). ASU 2014-09 supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue when they transfer promised goods or services to customers, in an amount that reflects the consideration that the entity expects to be entitled to in exchange for such goods or services. As currently issued and amended, ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, though early adoption is permitted for annual reporting periods beginning after December 15, 2016. In December 2016, the FASB issued guidance on Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. The new revenue standard may be applied retrospectively to each prior period presented " full retrospective modified retrospective In January 2016, FASB issued Accounting Standards Update 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10) (ASU 2016-01). The new standard provides guidance for the recognition, measurement, presentation and disclosure of financial instruments. This guidance is effective for annual and interim periods beginning after December 15, 2017 and early adoption is not permitted. The Company is currently evaluating the impact of the adoption of ASU 2016-01 on its consolidated financial statements. In February 2016, FASB issued Accounting Standards Update No. 2016-02, Leases (ASU 2016-02). The new guidance generally requires an entity to recognize on its balance sheet operating and financing lease liabilities and corresponding right-of-use assets. The standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2018 and early adoption is permitted. The new standard requires a modified retrospective transition for existing leases to each prior reporting period presented. The Company is currently evaluating the impact of the adoption of ASU 2016-02 on its consolidated financial statements. In August 2016, FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Subtopic 230) (ASU 2016-15). The new guidance provides clarity around the cash flow classification for specific issues in an effort to reduce the current and potential future diversity in practice. The standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2017 and early adoption is permitted. The Company is currently evaluating the impact of the adoption of ASU 2016-15 on its consolidated financial statements. In November 2016, FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Subtopic 230) (ASU 2016-18). The new guidance requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2017 and early adoption is permitted. The Company is currently evaluating the impact of the adoption of ASU 2016-18 on its consolidated financial statements. |
