NOTE 1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | |||||||||||
Rocket Fuel Inc. (the "Company") was incorporated as a Delaware corporation on March 25, 2008. The Company is a provider of an artificial-intelligence digital advertising solution. The Company is headquartered in Redwood City, California, and has offices in seven cities in the United States. The Company established a wholly-owned subsidiary in the United Kingdom, with an office in the Netherlands, in 2011 and wholly-owned subsidiaries in Germany and Canada in 2013. | |||||||||||
In September 2013, the Company completed the initial public offering of its common stock (the "IPO") whereby 4,000,000 shares of common stock were sold by the Company and 600,000 shares of common stock were sold by selling stockholders. The public offering price of the shares sold in the offering was $29.00 per share. The Company did not receive any proceeds from the sale of shares by the selling stockholders. The total gross proceeds from the offering to the Company were $116.0 million. After deducting underwriters' discounts and commissions and offering expenses, the aggregate net proceeds received by the Company totaled approximately $103.3 million. | |||||||||||
Basis of Presentation—The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. | |||||||||||
Principles of Consolidation—The consolidated financial statements include the Company and its wholly-owned subsidiary, Rocket Fuel, Ltd., an England and Wales corporation, which is engaged in marketing and selling advertising campaigns. All intercompany transactions and balances have been eliminated in consolidation. | |||||||||||
Use of Estimates—The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosures 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. Actual results could differ from those estimates. | |||||||||||
Certain Significant Risks and Uncertainties—The Company is subject to those risks common in technology-driven markets, including, but not limited to, competitive forces, dependence on key personnel, customer demand for its solution, management of growth, the successful protection of its proprietary technologies, compliance with government regulations, and the possibility of not being able to obtain additional financing when needed. | |||||||||||
Foreign Currency Translation—The Company's foreign subsidiary records its assets, liabilities and results of operations in its local currency, which is their functional currency. The Company translates its subsidiary consolidated financial statements into U.S. dollars each reporting period for purposes of consolidation. | |||||||||||
Assets and liabilities of the Company's foreign subsidiary are translated at the period-end currency exchange rates, certain equity accounts are translated at historical exchange rates while revenue, expenses, gains and losses are translated at the average currency exchange rates in effect for the period. The effects of these translation adjustments are reported in a separate component of stockholders' equity titled accumulated other comprehensive loss. | |||||||||||
Fair Value of Financial Instruments—The Company's financial instruments consist principally of cash equivalents, accounts receivable, accounts payable, accrued liabilities, capital lease, term debt and line of credit. The fair value of the Company's cash equivalents is determined based on quoted prices in active markets for identical assets for its money market funds. The recorded values of the Company's accounts receivable, accounts payable and accrued liabilities approximate their current fair values due to the relatively short-term nature of these accounts. The Company believes that the fair value of the capital lease, term debt and line of credit approximates its recorded amount at December 31, 2013 as the interest rate on the capital lease, term debt and line of credit is variable and is based on market interest rates after consideration of default and credit risk. | |||||||||||
Cash and Cash Equivalents—Cash consists of cash maintained in checking and savings accounts. All highly liquid investments purchased with an original maturity date of 90 days or less at the date of purchase are considered to be cash equivalents. Cash equivalents consist of money market funds. | |||||||||||
Concentration of Credit Risk—Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist primarily of cash and accounts receivable. A significant portion of the Company's cash is held at one major financial institution, which management assesses to be of high credit quality. The Company has not experienced any losses in such accounts. | |||||||||||
The Company mitigates its credit risk with respect to accounts receivable by performing credit evaluations and monitoring its customers' accounts receivable balances. As of December 31, 2013, no single customer accounted for more than 10% of accounts receivable. As of December 31, 2012, one customer accounted for more than 10% of accounts receivable. | |||||||||||
During the years ended December 31, 2013, 2012 and 2011, no single customer represented more than 10% of revenue. | |||||||||||
Provision for Doubtful Accounts—The Company records a provision for doubtful accounts based on historical experience and a detailed assessment of the collectability of its accounts receivable. In estimating the allowance for doubtful accounts, management considers, among other factors, the aging of the accounts receivable, historical write-offs and the credit-worthiness of each customer. If circumstances change, such as higher-than-expected defaults or an unexpected material adverse change in a major customer's ability to meet its financial obligations, the Company's estimate of the recoverability of the amounts due could be reduced by a material amount. | |||||||||||
The following table presents the changes in the allowance for doubtful accounts (in thousands): | |||||||||||

Property and Equipment—Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the related assets. Maintenance and repairs are charged to expense as incurred, and improvements and betterments are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation or amortization, as applicable, are removed from the balance sheet and any resulting gain or loss is reflected in operations in the period realized. | |||||||||||
Construction in progress primarily includes costs related to the leasehold improvements associated with our new corporate headquarters in Redwood City, California and the recently leased New York, New York sales office. Construction in progress also includes network equipment infrastructure to support our data centers around the world. Interest capitalized during the periods presented was not material. | |||||||||||
Leasehold improvements are amortized on a straight-line basis over the term of the lease, or the useful life of the assets, whichever is shorter. Depreciation and amortization periods for the Company's property and equipment are as follows: | |||||||||||
Asset Classification | Estimated Useful Life | ||||||||||
Computer hardware and purchased software | 2 - 3 years | ||||||||||
Capitalized internal-use software costs | 2 - 3 years | ||||||||||
Office equipment, furniture and fixtures | 5 years | ||||||||||
Internal-Use Software Development Costs—The Company incurs costs to develop software for internal use. The Company expenses all costs that relate to the planning and post implementation phases of development as research and development expense. The Company capitalizes costs when preliminary efforts are successfully completed, management has authorized and committed project funding, and it is probable that the project will be completed and will be used as intended. Costs incurred for enhancements that are expected to result in additional material functionality are capitalized. The Company capitalized $6.3 million, $4.7 million and $2.6 million in internal-use software costs during the years ended December 31, 2013, 2012 and 2011, respectively, which are included in property, equipment and software—net on the consolidated balance sheets. | |||||||||||
Amortization commences when the website or software for internal use is ready for its intended use and the amortization period is the estimated useful life of the related asset, which is generally three years. Amortization expense totaled $3.4 million, $2.3 million and $1.5 million for the years ended December 31, 2013, 2012 and 2011, respectively. | |||||||||||
Impairment of Long-lived Assets—The Company periodically reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset is impaired or the estimated useful lives are no longer appropriate. If indicators of impairment exist and the undiscounted projected cash flows associated with such assets are less than the carrying amount of the asset, an impairment loss is recorded to write the assets down to their estimated fair values. Fair value is estimated based on discounted future cash flows. No impairment charges were recorded during the years ended December 31, 2013, 2012 and 2011. | |||||||||||
Revenue Recognition—The company generates revenue by delivering digital advertisements to Internet users through various channels, including display, mobile, social and video. | |||||||||||
The Company recognizes revenue when all four of the following criteria are met: | |||||||||||
• | |||||||||||
Persuasive evidence of an arrangement exists | |||||||||||
• | |||||||||||
Delivery has occurred or a service has been provided | |||||||||||
• | |||||||||||
Customer fees are fixed or determinable | |||||||||||
• | |||||||||||
Collection is reasonably assured | |||||||||||
Revenue arrangements are evidenced by a fully executed insertion order ("IO"). Generally, IOs state the number and type of advertising impressions (cost-per-thousand) to be delivered, the agreed upon rate for each delivered impression, and a fixed period of time for delivery. | |||||||||||
The Company determines collectability by performing ongoing credit evaluations and monitoring its customers' accounts receivable balances. For new customers and their agents, which may be advertising agencies or other third parties, the Company performs a credit check with an independent credit agency and may check credit references to determine creditworthiness. The Company only recognizes revenue when collection is reasonably assured. | |||||||||||
In the normal course of business, the Company frequently contracts with advertising agencies on behalf of their advertiser clients. The determination of whether revenue should be reported on a gross or net basis is based on an assessment of whether the Company is acting as the principal or an agent in the transaction. In determining whether the Company acts as the principal or an agent, the Company follows the accounting guidance for principal-agent considerations. While none of the factors identified in this guidance is individually considered presumptive or determinative, because the Company is the primary obligor and is responsible for (i) fulfilling the advertisement delivery, (ii) establishing the selling prices for delivery of the advertisements, and (iii) performing all billing and collection activities including retaining credit risk, the Company has concluded that it acts as the principal in the majority of these arrangements and therefore reports revenue earned and costs incurred on a gross basis. | |||||||||||
On occasion, the Company has offered customer incentive programs which provide rebates after achieving a specified level of advertising spending. The Company records reductions to revenue for estimated commitments related to these customer incentive programs. For transactions involving incentives, the Company recognizes revenue net of the estimated amount to be paid by rebate, provided that the rebate amount can be reasonably and reliably estimated and the other conditions for revenue recognition have been met. The Company's policy requires that, if rebates cannot be reliably estimated, revenue is not recognized until reliable estimates can be made or the rebate program lapses. | |||||||||||
Multiple-Element Arrangements—The Company enters into arrangements to sell advertising that includes different media placements or ad services that are delivered at the same time, or within close proximity of one another. Beginning on January 1, 2011, the Company adopted new authoritative guidance on multiple element arrangements, using the prospective method for all arrangements entered into or materially modified from the date of adoption. Under this new guidance, the Company allocates arrangement consideration in multiple-deliverable revenue arrangements at the inception of an 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. | |||||||||||
VSOE—The 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 stand-alone selling prices for these services fall within a reasonably narrow pricing range. The Company has not been able to establish VSOE for any of its advertising offerings. | |||||||||||
TPE—When 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 Company's 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 the selling prices of similar competitor services on a stand-alone basis. As a result, the Company has not been able to establish selling price based on TPE. | |||||||||||
BESP—When 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 stand-alone basis. BESP is generally used to allocate the selling price to deliverables in the Company's 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. In particular, the Company reviews multiple data points to determine BESP, including price lists used by the Company's sales team in pricing negotiations, historical average and median pricing achieved in prior contractual customer arrangements and input from the Company's sales operation department regarding what it believes the deliverables could be sold for on a stand-alone basis. BESP is determined at an advertising unit level that is consistent with the Company's underlying market strategy and stratified based on specific consideration of channel, geography, industry and size, as deemed necessary. | |||||||||||
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 the 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 advertising services as they are delivered, assuming all other revenue recognition criteria are met. Deferred revenue is comprised of contractual billings in excess of recognized revenue and payments received in advance of revenue recognition. | |||||||||||
Cost of Revenue—Cost of revenue consists primarily of media cost for advertising impressions purchased from real-time advertising exchanges and other third parties. Cost of revenue also includes third-party data center costs and the salaries and related costs of the Company's operations group. This group sets up, initiates and monitors the Company's advertising campaigns. In addition, depreciation of the data center equipment, rental payments to third-party vendors for data centers and amortization of capitalized internal-use software are included in cost of revenue. | |||||||||||
Research and Development—Research and development expenses include costs associated with the maintenance and ongoing development of the Company's technology, including compensation and employee benefits and allocated costs associated with the Company's engineering and research and development departments, as well as costs for contracted services and supplies. Allocated costs include charges for facilities, office expenses, telephones, and other miscellaneous expenses. The Company reviews costs incurred in the application development stage and assesses such costs for potential capitalization. | |||||||||||
Sales and Marketing—Sales and marketing expenses consist primarily of compensation (including commissions) and employee benefits of sales and marketing personnel and related support teams, allocated costs, certain advertising costs, travel, trade shows and marketing materials. Allocated costs include charges for facilities, office expenses, telephones, and other miscellaneous expenses. The Company incurred advertising costs of $3.6 million, $0.1 million and $0.1 million for the years ended December 31, 2013, 2012 and 2011, respectively. | |||||||||||
General and Administrative—General and administrative expenses include facilities costs, executive and administrative compensation and employee benefits, depreciation, professional services fees, insurance costs, bad debt and other allocated costs, such as facility-related expenses, supplies and other fixed costs. Allocated costs include charges for facilities, office expenses, telephones, and other miscellaneous expenses. | |||||||||||
Stock-based Compensation—The Company measures compensation expense for all stock-based payment awards, including stock options granted to employees, based on the estimated fair values on the date of the grant. The fair value of each stock option granted is estimated using the Black-Scholes option pricing model. Stock-based compensation is recognized on a straight-line basis over the requisite vesting period, net of estimated forfeitures. The forfeiture rate is based on an analysis of the Company's actual historical forfeitures. | |||||||||||
The Company accounts for stock options issued to non-employees based on the fair value of the awards determined using the Black-Scholes option pricing model. The fair value of stock options granted to non-employees is re-measured as the stock options vest, and the resulting change in fair value, if any, is recognized in the Company's consolidated statement of operations during the period the related services are rendered, generally between one and four years. | |||||||||||
Preferred Stock Warrant Liability—Freestanding warrants related to shares that are redeemable or contingently redeemable are classified as a liability on the Company's consolidated balance sheets. The fully vested convertible preferred stock warrants were subject to re-measurement at each balance sheet date, and any change in fair value is recognized as a component of other expense, net. As completion of the Company's initial public offering constituted a liquidation event, the convertible preferred stock warrants were converted into common stock or warrants to purchase common stock, and the liability was reclassified to additional paid-in capital as of December 31, 2013. | |||||||||||
Income Taxes—The Company accounts for income taxes using an asset and liability approach. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Operating loss and tax credit carry-forwards are measured by applying currently enacted tax laws. Valuation allowances are provided when necessary to reduce net deferred tax assets to an amount that is more likely than not to be realized. Due to uncertainty as to the realization of benefits from deferred tax assets, including net operating loss carry-forwards, research and development and other tax credits, the Company has provided a full valuation allowance reserved against such assets as of December 31, 2013, 2012 and 2011. | |||||||||||
The Company recognizes the tax effects of an uncertain tax position only if it is more likely than not to be sustained based solely on its technical merits as of the reporting date, and then, only in an amount more likely than not to be sustained upon review by the tax authorities. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes. | |||||||||||
Comprehensive Income (Loss)—In June 2011, the Financial Accounting Standards Board ("FASB") issued an accounting standards update that requires an entity to present the total of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. This guidance eliminates the option to present the components of other comprehensive income as part of the statement of equity. The Company retrospectively adopted these new standards in the first quarter of 2012 and has presented a separate consolidated statement of comprehensive loss for the years ended December 31, 2013, 2012 and 2011. | |||||||||||
Deferred Offering Costs—Deferred offering costs consisted primarily of direct incremental costs related to the Company's initial public offering of its common stock. Approximately $0.1 million of deferred offering costs are included in other assets on the Company's consolidated balance sheets as of December 31, 2013 and 2012, respectively. Upon completion of the initial public offering, these amounts were offset against the proceeds of the offering. | |||||||||||
Recently Issued and Adopted Accounting Pronouncements—Under the Jumpstart Our Business Startups Act, or JOBS Act, we qualify as an "emerging growth company." We have irrevocably elected to opt out of the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act, and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not "emerging growth companies." | |||||||||||
In February 2013, the FASB issued guidance that addresses the presentation of amounts reclassified from accumulated other comprehensive income. This guidance does not change current financial reporting requirements. Instead, an entity is required to cross-reference to other required disclosures that provide additional detail about amounts reclassified out of accumulated other comprehensive income. In addition, the guidance requires an entity to present significant amounts reclassified out of accumulated other comprehensive income by line item of net income if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. Adoption of this standard is required for periods beginning after December 15, 2012 for public companies. The adoption of this accounting standard did not have an impact on our consolidated financial position, results of operations and cash flows. | |||||||||||
In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (ASU 2013-11). The guidance requires an entity to present its unrecognized tax benefits net of its deferred tax assets when settlement in this manner is available under the tax law, which would be based on facts and circumstances as of the balance sheet reporting date and would not consider future events. Gross presentation of unrecognized tax benefit will still be required in the notes to the financial statements. ASU 2013-11 will apply on a prospective basis to all unrecognized tax benefits that exist at the effective date. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of ASU 2013-11 is not expected to have a material impact on our consolidated financial statements. | |||||||||||

FAIR VALUE MEASUREMENTS | ' | |||||||||||||
NOTE 2. FAIR VALUE MEASUREMENTS | ||||||||||||||
Fair value is defined as the price that would be received on sale of an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants at the measurement date. The FASB has established a fair value hierarchy that distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity's own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). | ||||||||||||||
The three levels of the fair value hierarchy under the guidance for fair value measurement are described below: | ||||||||||||||
Level 1 | Inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Pricing inputs are based upon quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. For securities, the valuations are based on quoted prices of the security that are readily and regularly available in an active market, and accordingly, a significant degree of judgment is not required. As of December 31, 2013, and 2012, the Company used Level 1 assumptions for its money market funds. | |||||||||||||
Level 2 | Pricing inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. As of December 31, 2013, and 2012, the Company did not have any Level 2 financial assets or liabilities. | |||||||||||||
Level 3 | Pricing inputs are generally unobservable for the assets or liabilities and include situations where there is little, if any, market activity for the investment. The inputs into the determination of fair value require management's judgment or estimation of assumptions that market participants would use in pricing the assets or liabilities. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models, and similar techniques. As of December 31, 2013, the Company did not have any Level 3 financial assets or liabilities. As of December 31, 2012, the Company used Level 3 assumptions for its convertible preferred stock warrant liability. | |||||||||||||
The carrying amounts of cash equivalents, accounts receivable, prepaid expenses, accounts payable and accrued liabilities approximate fair value due to the short-term nature of these items. Based on the borrowing rates currently available to the Company for debt with similar terms, the carrying value of the capital lease, term debt and line of credit approximate fair value (using Level 2 inputs). | ||||||||||||||
Level 3 was used to value our convertible preferred stock warrant liability, the value of which is determined based on an option-pricing model that takes into account the contract terms as well as multiple inputs, such as the Company's stock price, risk-free interest rates and expected volatility. Additional quantitative information related to the convertible preferred stock warrants is included in Note 9. | ||||||||||||||
The following tables set forth the Company's financial instruments that were measured at fair value on a recurring basis as of December 31, 2013 and 2012, by level within the fair value hierarchy. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability.

Line of Credit—In April 2010, the Company entered into a loan and security agreement, or the Comerica Agreement, with Comerica Bank, or Comerica, to establish a revolving line of credit for working capital purposes. The maximum amount available for borrowing under the revolving line of credit, as amended in June 2013, was not to exceed the lesser of $35.0 million or an amount equal to 85% of certain eligible accounts receivable. Eligible accounts excluded, among others, accounts that had aged over 120 days, and accounts in which 25% of the total account had aged over 120 days, and certain other accounts such as governmental, intercompany, employee and certain foreign accounts. The revolving line of credit had a maturity date of July 26, 2014 and could be repaid and redrawn at any time prior to the maturity date, at which time all advances and any accrued and unpaid interest were due and payable. Interest was charged at LIBOR, plus a 2.75% applicable margin, which equaled 2.99% as of December 31, 2012, respectively. As of December 31, 2013 and 2012, the Company had $0 and $1.9 million, respectively, outstanding under the revolving line of credit. | |||||
Term Debt—In March 2012, the Company amended the Comerica Agreement to provide for growth capital advances of up to $3.0 million. The Comerica Agreement was further amended in February 2013 to increase the growth capital advances to up to $15.0 million. Growth capital advances could be drawn on before February 13, 2014 and were payable in equal monthly installments beginning on March 13, 2014 and continuing over a twenty-four month period ending on February 13, 2016 when the remaining principal and any accrued and unpaid interest would be due and payable. Interest on outstanding balances was charged at LIBOR, plus a 4.75% applicable margin, which equaled 4.99% as of December 31, 2012, respectively. As of December 31, 2012, the principal amount of $5.0 million, respectively, was outstanding under the loan. | |||||
Venture Debt—In April 2010, the Company entered into a loan and security agreement with Venture Lending and Leasing, or the VLL Agreement, to provide for a growth capital loan of up to $1.0 million, which the Company drew in full concurrently upon entering into the VLL Agreement. The funds borrowed were used for general corporate purposes of the Company. The loan was payable in monthly installments of interest only for the first six months, and thereafter interest and principal was payable in 30 equal monthly installments. Interest accrued at a fixed rate of 13%. All receivables, equipment, fixtures, deposit accounts, investment property, and all other goods and personal property of the Company, whether tangible or intangible, were collateral on the loan. The Agreement contained certain conditions of default. As of December 31, 2012, the principal amount of $0.1 million was outstanding under the agreement. | |||||
In March 2013, the Company repaid the VLL growth capital loan in full per the terms of the VLL Agreement, upon which VLL's security interest in the Company's collateral was released, and the agreement was terminated. As such, no amounts were outstanding under the VLL Agreement as of December 31, 2013. | |||||
Loan Facility—On December 20, 2013, we entered into an Amended and Restated Revolving Credit and Term Loan Agreement, or the Loan Facility, with certain lenders, including Comerica Bank, as administrative agent for the lenders. The Loan Facility provides for an $80.0 million revolving credit facility, with a $5.0 million letter of credit subfacility and a $1.5 million swing line subfacility, and a $20.0 million secured term loan facility. The Loan Facility permits us, subject to certain requirements, to request an increase in the maximum revolving commitments under the Loan Facility by up to $25.0 million in additional revolving commitments. Revolving loans may be advanced under the Loan Facility in amounts up to the lesser of the $80.0 million maximum and a borrowing base equal to 85% of the value of our eligible accounts receivable. The borrowing base is subject to certain reserves and eligibility criteria. Comerica may also issue letters of credit under the subfacility up to $5.0 million, provided that the aggregate amount of advances outstanding under the revolving facility, the subfacility and the swing line facility do not exceed the lesser of the $80.0 million maximum and the borrowing base amount. If at any time the aggregate amounts outstanding under the revolving facility, the letter of credit subfacility and the swing line facility exceed the lesser of the $80.0 million maximum and the borrowing base then in effect, then we must make a prepayment in an amount sufficient to eliminate the excess. Term loans equal to $20.0 million were advanced to us under the term loan facility during December 2013. Loan proceeds may be used for general corporate purposes. We may prepay revolving loans and term loans under the Loan Facility in whole or in part at any time without premium or penalty, subject to certain conditions. | |||||
Revolving loans bear interest, at our option, at (i) a base rate determined pursuant to the terms of the Loan Facility, plus a spread of 1.75% to 2.50%, or (ii) a LIBOR rate determined pursuant to the terms of the Loan Facility, plus a spread of 2.75% to 3.50%. Term loans bear interest, at our option, at (i) a base rate determined pursuant to the terms of the Loan Facility, plus a spread of 2.75% to 3.50%, or (ii) a LIBOR rate determined pursuant to the terms of the Loan Facility, plus a spread of 3.75% to 4.50%. In each case, the spread is based on the cash reflected on our balance sheet for the preceding fiscal quarter. The base rate is determined by taking the greatest of (i) the prime rate announced by Comerica, (ii) the federal funds rate plus 1.0% and (iii) the daily adjusting LIBOR rate plus 1.0%. Interest is due and payable quarterly in arrears for base rate loans. Interest is due and payable at the end of an interest period (or at each three month interval in the case of loans with interest periods greater than three months) for LIBOR rate loans. Term loans will be repaid in quarterly principal installments of approximately $1.3 million commencing in January 2015, with any remaining principal, together with all accrued and unpaid interest, due and payable on December 20, 2018. Principal, together with all accrued and unpaid interest, on the revolving loans are due and payable on December 20, 2016. | |||||
We are required to maintain certain financial covenants under the Loan Facility, including the following: | |||||
EBITDA. We are required to maintain specified quarterly EBITDA, which is defined for this purpose, with respect to any fiscal period as an amount equal to the sum of (i) consolidated net income (loss) in accordance with GAAP, after eliminating all extraordinary nonrecurring items of income, plus (ii) depreciation and amortization, income tax expense, total interest expense paid or accrued, non-cash stock-based compensation expense, costs and expenses from permitted acquisitions up to certain limits, costs and expenses in connection with the Loan Facility and any other expenses agreed with Comerica and the lenders less (iii) all extraordinary and non-recurring revenue and gains (including income tax benefits). | |||||
Liquidity ratio. Under the Loan Facility, the ratio of (i) the sum of all cash on deposit with Comerica and certain other domestic financial institutions and the aggregate amount of all eligible accounts receivable to (ii) all indebtedness owing to the lender of the Loan Facility must be at least 1.10 to 1.00. | |||||
The terms of the Loan Facility also require us to comply with certain non-financial covenants. As of December 31, 2013, we were in compliance with each of the financial and non-financial covenants. | |||||
Covenants | |||||
As of December 31, 2012, the Company was not in compliance with various financial and non-financial covenants under the April 2010 Comerica Loan and Security Agreement. However, the Company subsequently obtained a waiver for each of the covenant violations. As of December 31, 2012, the Company was in breach of the covenant under the VLL Agreement requiring submission of monthly consolidated financial statements within 30 days of month end. As of March 31, 2013, the VLL Agreement had been terminated upon repayment. Hence, a waiver was not required. | |||||

Warrants—In April 2010, the Company issued a fully vested warrant to purchase 161,533 shares of Series A preferred stock at an exercise price of $0.9286 per share. The warrant was issued in connection with the Company entering into a loan and security agreement. The warrant expires 10 years from the date of issuance. The fair value of the warrant at issuance was $22,000 based on the Company's option-pricing model, which approximates a binomial lattice model, using the weighted-average assumptions of 0% dividend yield, 70.5% volatility, risk-free interest rate of 3.96% and contractual life of 10 years. The warrant was outstanding as of December 31, 2012. | |||||||||||||||||
On September 25, 2013, upon closing of the Company's IPO, the warrant converted from a warrant to purchase Series A preferred stock to common stock, and the liability at its then fair value of $4.5 million was reclassified to additional paid-in capital.

2008 Equity Incentive Plan—The 2008 Equity Incentive Plan (the "2008 Plan") provides for the grant of incentive stock options and nonqualified stock options. The compensation committee of the Board of Directors has the authority to approve the employees and non-employees to whom options are granted and determine the terms of each option, including (i) the number of shares of common stock subject to the option; (ii) when the option becomes exercisable; (iii) the option exercise price, which, in the case of incentive stock options, must be at least 100% of the fair market value of the common stock as of the date of grant; and (iv) the duration of the option (which, in the case of incentive stock options, may not exceed 10 years). Options granted under the 2008 Plan generally vest over four years and expire no later than 10 years from the date of grant. As of December 31, 2012 and 2011, 14,738 and 33,080 shares of common stock, respectively, were available for future grant under the 2008 Plan.

2013 Equity Incentive Plan—The Company's board of directors adopted and the Company's stockholders approved a 2013 Equity Incentive Plan (the "2013 Plan"), and the 2013 Plan became effective September 18, 2013. The 2013 Plan permits the grant of incentive stock options, within the meaning of Section 422 of the Code, to the Company's employees and any parent and subsidiary corporations' employees, and for the grant of nonstatutory stock options, restricted stock, restricted stock units, stock appreciation rights, performance units and performance shares to the Company's employees, directors and consultants and the Company's parent and subsidiary corporations' employees and consultants. | |||||||||||||||||
Under the 2013 Plan, a total of 5,000,000 shares of common stock have been reserved for issuance. In addition, the shares to be reserved for issuance under the 2013 Plan will also include shares subject to stock options or similar awards granted under the 2008 Plan that expire or terminate without having been exercised in full and shares issued pursuant to awards granted under the 2008 Plan that are forfeited to or repurchased by the Company (provided that the maximum number of shares that may be added to the 2013 Plan pursuant to this provision is 7,900,000 shares). | |||||||||||||||||
The number of shares available for issuance under the 2013 Plan will also include an annual increase on the first day of each fiscal year beginning in 2014, equal to the least of (i) 4,000,000 shares; (ii) 5% of the outstanding shares of common stock as of the last day of the immediately preceding fiscal year; or (iii) such other amount as the Company's board of directors may determine. | |||||||||||||||||
The compensation committee of the board of directors has the authority to approve the employees and other service providers to whom equity awards are granted and to determine the terms of each award, subject to the terms of the 2013 Plan. The compensation committee may determine the number of shares subject to an award, except that the 2013 Plan provides certain limits on the number of awards that may be granted to non-employee members of the board of directors under the 2013 Plan in any fiscal year. Options and stock appreciation rights granted under the 2013 Plan must have a per share exercise price equal to at least 100% of the fair market value of a shares of the common stock as of the date of grant and may not expire later than 10 years from the date of grant. | |||||||||||||||||

Employee Stock-based Compensation—The fair value of options on the date of grant is estimated based on the Black-Scholes option-pricing model using the single-option award approach with the weighted-average assumptions set forth below. Expected term represents the period that the Company's stock-based awards are expected to be outstanding and is determined based on the simplified method. Volatility is estimated using comparable public company volatility for similar option terms. The risk-free interest rate is determined using a U.S. Treasury rate for the period that coincides with the expected term. | |||||||||||||||||
As the Company has never paid cash dividends, and at present, has no intention to pay cash dividends in the future, expected dividends are zero. Expected forfeitures are based on the Company's historical experience. The Company uses the straight-line method for expense recognition. | |||||||||||||||||

The table above includes the impact of the issuance of restricted stock at fair value. | |||||||||||||||||
As of December 31, 2013, 2012 and 2011, unamortized stock-based compensation expense related to unvested common stock options was $21.7 million, $12.5 million and $0.7 million, respectively. The weighted-average period over which such stock-based compensation expense will be recognized is approximately 2.9 years. | |||||||||||||||||
Options to Non-employees—The Company did not grant any stock options to non-employees for the years ended December 31, 2012 or 2011. For the year ended December 31, 2013, the Company granted options to purchase a total of 8,500 shares of common stock to non-employees. The definition of an employee includes a non-employee director of the Company. Stock options granted to non-employees are recorded at their fair value on the measurement date. The measurement of stock-based compensation is subject to periodic adjustment as the underlying equity instruments vest. The fair value of options granted to consultants is expensed when vested. | |||||||||||||||||
The Company recorded stock-based compensation expense for options issued to non-employees under the 2008 Plan of approximately $0.1 million, $0.1 million and $0.0 million for the years ended December 31, 2013, 2012 and 2011, respectively. Options to non-employees of 8,900 and 12,400 were outstanding as of December 31, 2013 and 2012, respectively. | |||||||||||||||||
Restricted Stock—Pursuant to restricted stock purchase agreements, the Company issued a total of 13,571 and 68,815 shares for the year ended December 31, 2012 and 2011, respectively, and no shares for the year ended December 31, 2013, respectively. | |||||||||||||||||
Restricted Stock Units (RSUs)—During the year ended December 31, 2013, the Company granted 383,402 RSUs and 1,000 RSUs were cancelled.

At December 31, 2013, unrecognized compensation expense related to the RSUs was $14.5 million. The unrecognized compensation expense will be amortized on a straight-line basis through 2017. | |||||||||||||||||
Employee Stock Purchase Plan | |||||||||||||||||
In August 2013, the Company's board of directors adopted and the stockholders approved the Company's 2013 Employee Stock Purchase Plan (the "ESPP"), which became effective upon adoption by the Company's board of directors. The ESPP allows eligible employees to purchase shares of the Company's common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to any plan limitations. The offering periods generally start on the first trading day on or after June 1 and December 1 of each year and end on the first trading day on or before November 30 and May 31 approximately six months later. The administrator may, in its discretion, modify the terms of future offering periods. Due to the timing of the IPO, the first offering period started October 1, 2013 and will end on May 31, 2014. At the end of each offering period, employees are able to purchase shares at 85% of the lower of the fair market value of the Company's common stock on the first trading day of the offering period or on the last trading day of the offering period. There were no offerings of share purchase rights to employees under the Company's ESPP for the year ended December 31, 2013. At December 31, 2013, total compensation costs related to rights to purchase common shares under the ESPP but not yet vested were approximately $1.8 million, which will be recognized over the offering period. | |||||||||||||||||
The assumptions used to calculate our stock-based compensation for each stock purchase right granted under the ESPP were as follows: | |||||||||||||||||

NOTE 10. NET INCOME (LOSS) PER SHARE | |||||||||||
The Company calculates its basic and diluted net income (loss) per share attributable to common stockholders in conformity with the two-class method required for companies with participating securities. Under the two-class method, in periods when the Company has net income, net income attributable to common stockholders is determined by allocating undistributed earnings, calculated as net income less current period convertible preferred stock non-cumulative dividends, between common stock and convertible preferred stock. In computing diluted net income attributable to common stockholders, undistributed earnings are re-allocated to reflect the potential impact of dilutive securities. The Company's basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. The diluted net loss per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, convertible preferred stock, options to purchase common stock and preferred stock warrants are considered common stock equivalents but have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is antidilutive. | |||||||||||
Basic loss per share is calculated by dividing net loss by the weighted-average number of shares of common stock outstanding during the period, less shares subject to repurchase, and excludes any dilutive effects of employee stock-based awards and warrants. As the Company had net losses for the years ended December 31, 2013, 2012 and 2011, all potential common shares were determined to be anti-dilutive. | |||||||||||
The following table sets forth the computation of net loss per common share (in thousands, except per share amounts): | |||||||||||

NOTE 11. INCOME TAXES | |||||||||||
The Company accounts for income taxes in accordance with authoritative guidance, which requires the use of the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based upon the difference between the consolidated financial statement carrying amounts and the tax basis of assets and liabilities and are measured using the enacted tax rate expected to apply to taxable income in the years in which the differences are expected to be reversed. | |||||||||||

A valuation allowance is provided for deferred tax assets where the recoverability of the assets is uncertain. The determination to provide a valuation allowance is dependent upon the assessment of whether it is more likely than not that sufficient future taxable income will be generated to utilize the deferred tax assets. Based on the weight of the available evidence, which includes the Company's historical operating losses, lack of taxable income and the accumulated deficit, the Company provided a full valuation allowance against the deferred tax assets resulting from the tax loss and credits carried forward. As of December 31, 2013, the Company had net operating loss carry-forwards of approximately $43.9 million for federal income taxes and $18.4 million for state income taxes. If not utilized, these carry-forwards will begin to expire in 2029 for both federal purposes and state purposes. | |||||||||||
As of December 31, 2013, the Company had research and development credit carry-forwards of approximately $1.7 million and $1.7 million for federal and state income taxes, respectively. If not utilized, the federal carry-forwards will begin to expire in various amounts beginning in 2029. The state tax credit can be carried forward indefinitely. | |||||||||||
A stock option exercise may result in a tax deduction prior to the actual realization of the related tax benefit because the Company has a net operating loss carry-forward. In that situation, a tax benefit and a credit to additional paid-in capital for the excess federal and California deduction of $(8.3) million and $(1.0) million would not be recognized until that deduction reduces taxes payable. | |||||||||||
Internal Revenue Code Section 382 limits the use of net operating loss and tax credit carry-forwards in certain situations where changes occur in the stock ownership of a company. If the Company has a change of ownership, then utilization of the net operating loss and tax credit carry-forwards may be restricted. | |||||||||||
On January 1, 2009, the Company adopted ASC 740-10 (formerly referred to as FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109). ASC 740-10 requires that the tax effects of a position be recognized only if it is "more likely than not" to be sustained based solely on its technical merits as of the reporting date. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes. | |||||||||||
With the adoption of ASC 740-10, companies are required to adjust their financial statements to reflect only those tax positions that are more likely than not to be sustained. Any necessary adjustment would be recorded directly to retained earnings and reported as a change in accounting principle as of the date of adoption. ASC 740-10 prescribes a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns. The implementation of ASC 740, did not result in any material changes to the liability for unrecognized tax benefits. | |||||||||||
The table below provides a reconciliation of the beginning and ending amount of unrecognized tax benefits (excluding interest and penalties) for the years ended December 31, 2013, 2012 and 2011 (in thousands): | |||||||||||

Indemnification Agreements—In the ordinary course of business, the Company may provide indemnifications of varying scope and terms to customers, vendors, lessors, business partners, and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements, services to be provided by the Company or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with directors and certain officers and employees that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or employees. No demands have been made upon the Company to provide indemnification under such agreements, and thus there are no claims that the Company is aware of that could have a material effect on the Company's consolidated balance sheets, consolidated statements of operations, consolidated statements of comprehensive loss, or consolidated statements of cash flows. | |||||

NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | ' | ||||||||||
Principles of Consolidation | ' | ||||||||||
Principles of Consolidation—The consolidated financial statements include the Company and its wholly-owned subsidiary, Rocket Fuel, Ltd., an England and Wales corporation, which is engaged in marketing and selling advertising campaigns. All intercompany transactions and balances have been eliminated in consolidation. | |||||||||||
Use of Estimates | ' | ||||||||||
Use of Estimates—The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosures 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. Actual results could differ from those estimates. | |||||||||||
Certain Significant Risks and Uncertainties | ' | ||||||||||
Certain Significant Risks and Uncertainties—The Company is subject to those risks common in technology-driven markets, including, but not limited to, competitive forces, dependence on key personnel, customer demand for its solution, management of growth, the successful protection of its proprietary technologies, compliance with government regulations, and the possibility of not being able to obtain additional financing when needed. | |||||||||||
Foreign Currency Translation | ' | ||||||||||
Foreign Currency Translation—The Company's foreign subsidiary records its assets, liabilities and results of operations in its local currency, which is their functional currency. The Company translates its subsidiary consolidated financial statements into U.S. dollars each reporting period for purposes of consolidation. | |||||||||||
Assets and liabilities of the Company's foreign subsidiary are translated at the period-end currency exchange rates, certain equity accounts are translated at historical exchange rates while revenue, expenses, gains and losses are translated at the average currency exchange rates in effect for the period. The effects of these translation adjustments are reported in a separate component of stockholders' equity titled accumulated other comprehensive loss. | |||||||||||
Fair Value of Financial Instruments | ' | ||||||||||
Fair Value of Financial Instruments—The Company's financial instruments consist principally of cash equivalents, accounts receivable, accounts payable, accrued liabilities, capital lease, term debt and line of credit. The fair value of the Company's cash equivalents is determined based on quoted prices in active markets for identical assets for its money market funds. The recorded values of the Company's accounts receivable, accounts payable and accrued liabilities approximate their current fair values due to the relatively short-term nature of these accounts. The Company believes that the fair value of the capital lease, term debt and line of credit approximates its recorded amount at December 31, 2013 as the interest rate on the capital lease, term debt and line of credit is variable and is based on market interest rates after consideration of default and credit risk. | |||||||||||
Cash and Cash Equivalents | ' | ||||||||||
Cash and Cash Equivalents—Cash consists of cash maintained in checking and savings accounts. All highly liquid investments purchased with an original maturity date of 90 days or less at the date of purchase are considered to be cash equivalents. Cash equivalents consist of money market funds. | |||||||||||
Concentration of Credit Risk | ' | ||||||||||
Concentration of Credit Risk—Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist primarily of cash and accounts receivable. A significant portion of the Company's cash is held at one major financial institution, which management assesses to be of high credit quality. The Company has not experienced any losses in such accounts. | |||||||||||
The Company mitigates its credit risk with respect to accounts receivable by performing credit evaluations and monitoring its customers' accounts receivable balances. As of December 31, 2013, no single customer accounted for more than 10% of accounts receivable. As of December 31, 2012, one customer accounted for more than 10% of accounts receivable. | |||||||||||
During the years ended December 31, 2013, 2012 and 2011, no single customer represented more than 10% of revenue. | |||||||||||
Provision for Doubtful Accounts | ' | ||||||||||
Provision for Doubtful Accounts—The Company records a provision for doubtful accounts based on historical experience and a detailed assessment of the collectability of its accounts receivable. In estimating the allowance for doubtful accounts, management considers, among other factors, the aging of the accounts receivable, historical write-offs and the credit-worthiness of each customer. If circumstances change, such as higher-than-expected defaults or an unexpected material adverse change in a major customer's ability to meet its financial obligations, the Company's estimate of the recoverability of the amounts due could be reduced by a material amount. | |||||||||||

Property and Equipment | ' | ||||||||||
Property and Equipment—Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the related assets. Maintenance and repairs are charged to expense as incurred, and improvements and betterments are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation or amortization, as applicable, are removed from the balance sheet and any resulting gain or loss is reflected in operations in the period realized. | |||||||||||
Construction in progress primarily includes costs related to the leasehold improvements associated with our new corporate headquarters in Redwood City, California and the recently leased New York, New York sales office. Construction in progress also includes network equipment infrastructure to support our data centers around the world. Interest capitalized during the periods presented was not material. | |||||||||||
Leasehold improvements are amortized on a straight-line basis over the term of the lease, or the useful life of the assets, whichever is shorter. Depreciation and amortization periods for the Company's property and equipment are as follows: | |||||||||||
Asset Classification | Estimated Useful Life | ||||||||||
Computer hardware and purchased software | 2 - 3 years | ||||||||||
Capitalized internal-use software costs | 2 - 3 years | ||||||||||
Office equipment, furniture and fixtures | 5 years | ||||||||||
Internal Use Software Development Costs | ' | ||||||||||
Internal-Use Software Development Costs—The Company incurs costs to develop software for internal use. The Company expenses all costs that relate to the planning and post implementation phases of development as research and development expense. The Company capitalizes costs when preliminary efforts are successfully completed, management has authorized and committed project funding, and it is probable that the project will be completed and will be used as intended. Costs incurred for enhancements that are expected to result in additional material functionality are capitalized. The Company capitalized $6.3 million, $4.7 million and $2.6 million in internal-use software costs during the years ended December 31, 2013, 2012 and 2011, respectively, which are included in property, equipment and software—net on the consolidated balance sheets. | |||||||||||
Amortization commences when the website or software for internal use is ready for its intended use and the amortization period is the estimated useful life of the related asset, which is generally three years. Amortization expense totaled $3.4 million, $2.3 million and $1.5 million for the years ended December 31, 2013, 2012 and 2011, respectively. | |||||||||||
Impairment of Long-lived Asset | ' | ||||||||||
Impairment of Long-lived Assets—The Company periodically reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset is impaired or the estimated useful lives are no longer appropriate. If indicators of impairment exist and the undiscounted projected cash flows associated with such assets are less than the carrying amount of the asset, an impairment loss is recorded to write the assets down to their estimated fair values. Fair value is estimated based on discounted future cash flows. No impairment charges were recorded during the years ended December 31, 2013, 2012 and 2011. | |||||||||||
Revenue Recognition | ' | ||||||||||
Revenue Recognition—The company generates revenue by delivering digital advertisements to Internet users through various channels, including display, mobile, social and video. | |||||||||||
The Company recognizes revenue when all four of the following criteria are met: | |||||||||||
• | |||||||||||
Persuasive evidence of an arrangement exists | |||||||||||
• | |||||||||||
Delivery has occurred or a service has been provided | |||||||||||
• | |||||||||||
Customer fees are fixed or determinable | |||||||||||
• | |||||||||||
Collection is reasonably assured | |||||||||||
Revenue arrangements are evidenced by a fully executed insertion order ("IO"). Generally, IOs state the number and type of advertising impressions (cost-per-thousand) to be delivered, the agreed upon rate for each delivered impression, and a fixed period of time for delivery. | |||||||||||
The Company determines collectability by performing ongoing credit evaluations and monitoring its customers' accounts receivable balances. For new customers and their agents, which may be advertising agencies or other third parties, the Company performs a credit check with an independent credit agency and may check credit references to determine creditworthiness. The Company only recognizes revenue when collection is reasonably assured. | |||||||||||
In the normal course of business, the Company frequently contracts with advertising agencies on behalf of their advertiser clients. The determination of whether revenue should be reported on a gross or net basis is based on an assessment of whether the Company is acting as the principal or an agent in the transaction. In determining whether the Company acts as the principal or an agent, the Company follows the accounting guidance for principal-agent considerations. While none of the factors identified in this guidance is individually considered presumptive or determinative, because the Company is the primary obligor and is responsible for (i) fulfilling the advertisement delivery, (ii) establishing the selling prices for delivery of the advertisements, and (iii) performing all billing and collection activities including retaining credit risk, the Company has concluded that it acts as the principal in the majority of these arrangements and therefore reports revenue earned and costs incurred on a gross basis. | |||||||||||
On occasion, the Company has offered customer incentive programs which provide rebates after achieving a specified level of advertising spending. The Company records reductions to revenue for estimated commitments related to these customer incentive programs. For transactions involving incentives, the Company recognizes revenue net of the estimated amount to be paid by rebate, provided that the rebate amount can be reasonably and reliably estimated and the other conditions for revenue recognition have been met. The Company's policy requires that, if rebates cannot be reliably estimated, revenue is not recognized until reliable estimates can be made or the rebate program lapses. | |||||||||||
Multiple-Element Arrangements | ' | ||||||||||
Multiple-Element Arrangements—The Company enters into arrangements to sell advertising that includes different media placements or ad services that are delivered at the same time, or within close proximity of one another. Beginning on January 1, 2011, the Company adopted new authoritative guidance on multiple element arrangements, using the prospective method for all arrangements entered into or materially modified from the date of adoption. Under this new guidance, the Company allocates arrangement consideration in multiple-deliverable revenue arrangements at the inception of an 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. | |||||||||||
VSOE—The 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 stand-alone selling prices for these services fall within a reasonably narrow pricing range. The Company has not been able to establish VSOE for any of its advertising offerings. | |||||||||||
TPE—When 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 Company's 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 the selling prices of similar competitor services on a stand-alone basis. As a result, the Company has not been able to establish selling price based on TPE. | |||||||||||
BESP—When 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 stand-alone basis. BESP is generally used to allocate the selling price to deliverables in the Company's 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. In particular, the Company reviews multiple data points to determine BESP, including price lists used by the Company's sales team in pricing negotiations, historical average and median pricing achieved in prior contractual customer arrangements and input from the Company's sales operation department regarding what it believes the deliverables could be sold for on a stand-alone basis. BESP is determined at an advertising unit level that is consistent with the Company's underlying market strategy and stratified based on specific consideration of channel, geography, industry and size, as deemed necessary. | |||||||||||
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 the 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 advertising services as they are delivered, assuming all other revenue recognition criteria are met. Deferred revenue is comprised of contractual billings in excess of recognized revenue and payments received in advance of revenue recognition. | |||||||||||
Cost of Revenue | ' | ||||||||||
Cost of Revenue—Cost of revenue consists primarily of media cost for advertising impressions purchased from real-time advertising exchanges and other third parties. Cost of revenue also includes third-party data center costs and the salaries and related costs of the Company's operations group. This group sets up, initiates and monitors the Company's advertising campaigns. In addition, depreciation of the data center equipment, rental payments to third-party vendors for data centers and amortization of capitalized internal-use software are included in cost of revenue. | |||||||||||
Research and Development | ' | ||||||||||
Research and Development—Research and development expenses include costs associated with the maintenance and ongoing development of the Company's technology, including compensation and employee benefits and allocated costs associated with the Company's engineering and research and development departments, as well as costs for contracted services and supplies. Allocated costs include charges for facilities, office expenses, telephones, and other miscellaneous expenses. The Company reviews costs incurred in the application development stage and assesses such costs for potential capitalization. | |||||||||||
Sales and Marketing | ' | ||||||||||
Sales and Marketing—Sales and marketing expenses consist primarily of compensation (including commissions) and employee benefits of sales and marketing personnel and related support teams, allocated costs, certain advertising costs, travel, trade shows and marketing materials. Allocated costs include charges for facilities, office expenses, telephones, and other miscellaneous expenses. The Company incurred advertising costs of $3.6 million, $0.1 million and $0.1 million for the years ended December 31, 2013, 2012 and 2011, respectively. | |||||||||||
General and Administrative | ' | ||||||||||
General and Administrative—General and administrative expenses include facilities costs, executive and administrative compensation and employee benefits, depreciation, professional services fees, insurance costs, bad debt and other allocated costs, such as facility-related expenses, supplies and other fixed costs. Allocated costs include charges for facilities, office expenses, telephones, and other miscellaneous expenses. | |||||||||||
Stock-Based Compensation | ' | ||||||||||
Stock-based Compensation—The Company measures compensation expense for all stock-based payment awards, including stock options granted to employees, based on the estimated fair values on the date of the grant. The fair value of each stock option granted is estimated using the Black-Scholes option pricing model. Stock-based compensation is recognized on a straight-line basis over the requisite vesting period, net of estimated forfeitures. The forfeiture rate is based on an analysis of the Company's actual historical forfeitures. | |||||||||||
The Company accounts for stock options issued to non-employees based on the fair value of the awards determined using the Black-Scholes option pricing model. The fair value of stock options granted to non-employees is re-measured as the stock options vest, and the resulting change in fair value, if any, is recognized in the Company's consolidated statement of operations during the period the related services are rendered, generally between one and four years. | |||||||||||
Preferred Stock Warrant Liability | ' | ||||||||||
Preferred Stock Warrant Liability—Freestanding warrants related to shares that are redeemable or contingently redeemable are classified as a liability on the Company's consolidated balance sheets. The fully vested convertible preferred stock warrants were subject to re-measurement at each balance sheet date, and any change in fair value is recognized as a component of other expense, net. As completion of the Company's initial public offering constituted a liquidation event, the convertible preferred stock warrants were converted into common stock or warrants to purchase common stock, and the liability was reclassified to additional paid-in capital as of December 31, 2013. | |||||||||||
Income Taxes | ' | ||||||||||
Income Taxes—The Company accounts for income taxes using an asset and liability approach. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Operating loss and tax credit carry-forwards are measured by applying currently enacted tax laws. Valuation allowances are provided when necessary to reduce net deferred tax assets to an amount that is more likely than not to be realized. Due to uncertainty as to the realization of benefits from deferred tax assets, including net operating loss carry-forwards, research and development and other tax credits, the Company has provided a full valuation allowance reserved against such assets as of December 31, 2013, 2012 and 2011. | |||||||||||
The Company recognizes the tax effects of an uncertain tax position only if it is more likely than not to be sustained based solely on its technical merits as of the reporting date, and then, only in an amount more likely than not to be sustained upon review by the tax authorities. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes. | |||||||||||
Comprehensive Income (Loss) | ' | ||||||||||
Comprehensive Income (Loss)—In June 2011, the Financial Accounting Standards Board ("FASB") issued an accounting standards update that requires an entity to present the total of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. This guidance eliminates the option to present the components of other comprehensive income as part of the statement of equity. The Company retrospectively adopted these new standards in the first quarter of 2012 and has presented a separate consolidated statement of comprehensive loss for the years ended December 31, 2013, 2012 and 2011. | |||||||||||
Deferred Offering Costs | ' | ||||||||||
Deferred Offering Costs—Deferred offering costs consisted primarily of direct incremental costs related to the Company's initial public offering of its common stock. Approximately $0.1 million of deferred offering costs are included in other assets on the Company's consolidated balance sheets as of December 31, 2013 and 2012, respectively. Upon completion of the initial public offering, these amounts were offset against the proceeds of the offering. | |||||||||||
Recently Issued and Adopted Accounting Pronouncements | ' | ||||||||||
Recently Issued and Adopted Accounting Pronouncements—Under the Jumpstart Our Business Startups Act, or JOBS Act, we qualify as an "emerging growth company." We have irrevocably elected to opt out of the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act, and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not "emerging growth companies." | |||||||||||
In February 2013, the FASB issued guidance that addresses the presentation of amounts reclassified from accumulated other comprehensive income. This guidance does not change current financial reporting requirements. Instead, an entity is required to cross-reference to other required disclosures that provide additional detail about amounts reclassified out of accumulated other comprehensive income. In addition, the guidance requires an entity to present significant amounts reclassified out of accumulated other comprehensive income by line item of net income if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. Adoption of this standard is required for periods beginning after December 15, 2012 for public companies. The adoption of this accounting standard did not have an impact on our consolidated financial position, results of operations and cash flows. | |||||||||||
In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (ASU 2013-11). The guidance requires an entity to present its unrecognized tax benefits net of its deferred tax assets when settlement in this manner is available under the tax law, which would be based on facts and circumstances as of the balance sheet reporting date and would not consider future events. Gross presentation of unrecognized tax benefit will still be required in the notes to the financial statements. ASU 2013-11 will apply on a prospective basis to all unrecognized tax benefits that exist at the effective date. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of ASU 2013-11 is not expected to have a material impact on our consolidated financial statements. | |||||||||||
