Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation and Consolidation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The Company’s consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Actual results may differ from the Company’s estimates, and such differences may be material to the accompanying consolidated financial statements. Cash, Cash Equivalents and Short-term Investments The Company considers all highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. The Company’s short-term investments consists of certificates of deposits with original maturities of greater than three months and remaining maturities less than one year as of the balance sheet date. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at invoiced amounts and do not bear interest. The Company generally does not require collateral and performs ongoing credit evaluations of its customers and maintains allowances for potential credit losses. The Company maintains an allowance for doubtful accounts based upon the expected collectability of its accounts receivable. The allowance is determined based upon specific account identification Property and Equipment, net Property and equipment, net, are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets, which are three years for computer equipment and software and five years for all other asset categories except leasehold improvements, which are amortized over the shorter of the lease term or the expected useful life of the improvements. Equipment leased under capital leases is amortized over the shorter of the lease term or the asset’s estimated useful life. Internal-Use Software Development Costs C osts incurred for computer software developed or obtained for internal use, the Company begins to capitalize 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. These costs are amortized to cost of revenues over the estimated useful life of the related asset, generally estimated to be three years. Costs incurred prior to meeting these criteria together with costs incurred for training and maintenance are expensed as incurred and recorded in research and development expense on the Company’s consolidated statements of operations. Leases Leases meeting certain criteria are accounted for as capital leases. The imputed interest is included in interest expense in the accompanying consolidated statements of operations, and the capitalized value is amortized as part of the Company’s property and equipment, net. Obligations under capital leases are reduced by lease payments, net of imputed interest. All other leases are accounted for as operating leases. When an operating lease contains a predetermined fixed escalation of the minimum rent, or if tenant allowances have been received, the related rent expense is recognized on a straight-line basis over the term of the lease, with the difference between the recognized rent expense and amounts payable under the lease recorded as deferred rent liability. Business Combinations The Company accounts for acquisitions of entities that include inputs and processes and have the ability to create outputs as business combinations. Under the acquisition method of accounting, the total consideration is allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition dates. The excess of the consideration transferred over those fair values is recorded as goodwill. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Acquisition related costs are not considered part of the consideration, and are expensed as general and administrative expense as incurred. Goodwill and Intangible Assets, net Intangible assets with a finite life are amortized over their estimated useful lives. Goodwill is tested for impairment at least annually, and more frequently upon the occurrence of certain events. The Company completes its annual impairment test during the fourth quarter of each year. There was no impairment of goodwill for the years ended December 31, 2015, 2014 and 2013. Impairment of Long-Lived Assets Long-lived assets are reviewed 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 first 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, an impairment loss would be recognized when the carrying amount of the asset exceeds the fair value of the asset. The Company has not recognized any impairment of long-lived assets for the years ended December 31, 2015, 2014 and 2013. Fair Value of Financial Instruments The carrying values of the Company’s financial instruments, including cash equivalents, accounts receivable, accounts payable, accrued compensation and benefits, and other current liabilities, approximate fair value due to their short-term nature. Debt obligations are stated at the carrying value as the stated interest rates approximate market rates available to the Company. The Company records money market funds, short-term investments and contingent consideration at fair value. See Note 3 (Fair Value Measurements) Revenue Recognition The Company derives revenues primarily from the set-up and activation of coupons and coupons codes, and digital media services. 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; and · Collection is reasonably assured. Coupons. The Company generates revenues, as consumers select, activate, or redeem a coupon through our platform by either printing it for physical redemption at a retailer or saving it to a retailer loyalty account for automatic digital redemption. In the case of the setup fees, it recognizes revenues proportionally, on a per activation basis, using the number of authorized activations per insertion order, commencing on the date of the first coupon activation. For coupons, the pricing is generally determined on a per unit activation basis. Setup fees charged to customers represent charges for the creation of digital coupons and related activation, tracking and security features. Upfront insertion orders generally include a limit on the number of activations, or times consumers may select a coupon. Coupon Codes . The Company generally generates revenues when a consumer makes a purchase using a coupon code from its platform and completion of the order is reported to the Company. In the same period that the Company recognize revenues for the delivery of coupon codes, it also estimates and record a reserve, based upon historical experience, to provide for end-user cancelations or product returns which may not be reported until a subsequent date. Digital Media - The Company’s media services enable CPGs and retailers to deliver digital media and advertising to promote their brands and products on the Company’s websites and mobile apps, and through the Company’s affiliate publishers and non-publisher third parties. The Company charges a fee for these media campaigns, the pricing of which is based on the advertisement size and position. Related fees are generally billed monthly, based on a per-campaign, per-impression or per-click basis. The Company does not offer rights of refund of previously paid or delivered amounts, rebates, rights of return or price protection. In all instances, the Company limits the amount of revenue recognized to the amounts for which it have the right to bill its’ customers. Gross versus Net Revenue Reporting In the normal course of business and through its distribution network, the Company delivers digital coupons and media on retailers’ websites, through retailers’ loyalty programs, and on the websites of digital publishers. In these situations, the Company generally pays a distribution fee to the retailers or publishers which is included in the Company’s cost of revenues. The determination of whether revenues 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 is the principal or an agent, the Company follows the accounting guidance for principal-agent considerations. Because the Company is the primary obligor and is responsible for (i) fulfilling the digital coupon and media delivery, (ii) establishing the selling prices for delivery of the digital coupons and media, and (iii) performing all billing and collection activities including retaining credit risk, the Company has concluded that it is the principal in these arrangements and therefore the Company reports revenues and cost of revenues on a gross basis. Multiple-element Arrangements For arrangements with multiple-deliverables, the Company determines whether each of the individual deliverables qualify as a separate unit of accounting. In order to treat deliverables in a multiple element arrangement as a separate unit of accounting, the deliverable must have standalone value upon delivery. The Company allocates the arrangement fee to all the deliverables (separate units of accounting) using the relative selling price method in accordance with the selling price hierarchy, which includes vendor-specific objective evidence (“VSOE”) if available, third-party evidence (“TPE”) if VSOE is not available and best estimate of selling price (“BESP”) if neither VSOE nor TPE is available. VSOE and TPE do currently not exist for any of the Company’s deliverables. Accordingly, for arrangements with multiple deliverables that can be separated into different units of accounting, the Company allocates the arrangement fee to the separate units of accounting based on BESP. 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. Deferred Revenues Deferred revenues consist of coupon setup fees and activation fees that are expected to be recognized upon coupon activations, which generally occurs within the next twelve months. Cost of Revenues Cost of revenues consist primarily of distribution fees, third-party data center costs, personnel costs and depreciation and amortization expense. Distribution fees consist of payments to partners within the Company’s network for their digital coupon publishing services. Personnel costs include salaries, bonuses, stock-based awards and employee benefits. The personnel costs are primarily attributable to individuals maintaining the Company’s data centers and operations, which initiate, sets up and deliver digital coupon media campaigns. Depreciation and amortization expense includes depreciation of data center equipment and amortization of capitalized internal use software. Research and Development Expense The Company expenses the cost of research and development as incurred. Research and development expense consists primarily of personnel and related headcount costs and costs of professional services associated with the ongoing development of the Company’s technology. Stock-based Compensation The Company accounts for stock-based compensation using the fair value method, which requires the Company to measure the stock-based compensation based on the grant-date fair value of the awards and recognize the compensation expense over the requisite service period. The Company recognizes compensation expense net of estimated forfeitures. Equity awards issued to nonemployees are recorded at fair value on their measurement date and are subject to adjustment each period as the awards vest. The fair value of RSUs equals the market value of the Company’s common stock on the date of grant. RSUs granted prior to the Company’s IPO have a contractual term of seven years and vest upon the satisfaction of both a service condition and a liquidity-event condition. The service condition is satisfied as to 25% of the RSUs on each of the first four anniversaries of the vesting commencement date. The liquidity-event condition is satisfied upon the earlier of (i) six months after the effective date of the IPO or (ii) March 15 of the calendar year following the year in which the IPO was declared effective; and (iii) the time immediately prior to the consummation of a change in control. The vesting condition that was satisfied six months following the Company’s IPO did not affect the expense attribution period for the RSUs for which the service condition has been met as of the date of the Company’s IPO. This six-month period was not a substantive service condition and, accordingly, beginning on the effectiveness of the Company’s IPO in March 2014, the Company recognized a cumulative stock-based compensation expense for the portion of the RSUs that had met the service condition as of the date of the Company’s IPO. The Company recognized stock-based compensation expense associated with RSUs of $27.7 million and $29.5 million during the years ended December 31, 2015 and 2014, respectively. RSUs granted on or after the Company’s IPO have similar terms as the RSUs granted prior to the Company’s IPO, but are not subject to a liquidity-event condition in order to vest, and the compensation expense is recognized on a straight-line basis over the applicable service period. Advertising Expense Advertising costs are expensed when incurred and are included in sales and marketing expense on the accompanying consolidated statements of operations. The Company incurred $1.4 million, $0.8 million and $1.9 million of advertising costs during the years ended December 31, 2015, 2014 and 2013, respectively. Advertising costs consist primarily of online marketing costs, such as sponsored search, advertising on social networking sites, e-mail marketing campaigns, loyalty programs, and affiliate programs. Income Taxes The Company accounts for income taxes in accordance with authoritative guidance, which requires the use of the 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 reverse. A valuation allowance is provided when it is more likely than not that the deferred tax assets will not be realized. In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes The Company recognizes liabilities for uncertain tax positions based upon a two-step process. To the extent a tax position does not meet a more-likely-than-not level of certainty, no benefit is recognized in the consolidated financial statements. If a position meets the more-likely-than-not level of certainty, it is recognized in the consolidated financial statements at the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company accounts for any applicable interest and penalties as a component of income tax expense. Foreign Currency Foreign currency denominated assets and liabilities of foreign subsidiaries, where the local currency is the functional currency, are translated into U.S. Dollars using the exchange rates in effect at the balance sheet dates, and income and expenses are translated using average exchange rates during the period. The resulting foreign currency translation adjustments are recorded in accumulated other comprehensive income (loss), a component of stockholders’ equity. Gains and losses from foreign currency transactions are included in other income (expense), net in the accompanying consolidated statements of operations. Foreign currency transaction gains (losses) were immaterial for all the periods presented in the accompanying consolidated financial statements. Other Comprehensive Income (Loss) Other comprehensive income (loss) consists of foreign currency translation adjustments. Net Loss per Share Attributable to Common Stockholders The Company computes its basic and diluted net loss per share attributable to common stockholders using the two-class method required for companies with participating securities. The Company’s basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, less the weighted average unvested common stock subject to repurchase. The diluted net income per share attributable to common stockholders is computed by giving effect to all potentially dilutive common shares equivalents outstanding during the period. The effects of options to purchase common stock, redeemable convertible preferred stock (outstanding prior to the Company’s IPO in March 2014), RSUs, and common stock warrants are excluded from the computation of diluted net loss per share attributable to common stockholders because their effect is antidilutive. Segments The Company’s chief operating decision maker, who is the Chief Executive Officer, reviews the Company’s financial information presented on a consolidated basis for purposes of allocating resources and evaluating our financial performance. There are no segment managers who are held accountable by the chief operating decision maker, or anyone else, for operations, operating results, and planning for levels or components below the consolidated unit level. Accordingly, the Company has determined that it operates in a single reporting segment. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, short-term investments and accounts receivable. For cash, cash equivalents and short-term investments, the Company is exposed to credit risk in the event of default by the financial institutions to the extent of the amounts recorded on the accompanying consolidated balance sheets. Credit risk with respect to accounts receivable is dispersed due to the large number of customers. The Company does not require collateral for accounts receivable.

Fair Value Disclosures [Abstract]
Fair Value Measurements	3. Fair Value Measurements The fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: Level 1—Quoted prices in active markets for identical assets or liabilities. Level 2—Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for similar assets or liabilities in active or inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3—Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability. The Company’s fair value hierarchy for its financial assets and liabilities that are measured at fair value on a recurring basis are as follows (in thousands): December 31, 2015 Level 1 Level 2 Level 3 Total Assets: Money market funds (1) $ 19,948 $ — $ — $ 19,948 Certificate of deposits (2) — 25,000 — 25,000 Total $ 19,948 $ 25,000 $ — $ 44,948 Liabilities: Contingent consideration related to Eckim acquisition (3) $ 2,291 $ — $ — $ 2,291 Contingent consideration related to Shopmium acquisition — — 1,407 1,407 Total $ 2,291 $ — $ 1,407 $ 3,698 (1) Included in cash and cash equivalents (2) Included in short-term investments (3) Included in other current liabilities December 31, 2014 Level 1 Level 2 Level 3 Total Assets: Money market funds (1) $ 14,928 $ — $ — $ 14,928 Total $ 14,928 $ — $ — $ 14,928 Liabilities: Contingent consideration (2) $ — $ — $ 1,048 $ 1,048 Total $ — $ — $ 1,048 $ 1,048 (1) Included in cash and cash equivalents (2) Included in other current liabilities The valuation technique used to measure the fair value of money market funds included using quoted prices in active markets for identical assets. The valuation technique used to measure the fair value of certificate of deposits included using quoted prices in active markets for similar assets. The fair value of contingent consideration related to Eckim is the result of the earnout period ending for measuring shares issuable based on Eckim achieving certain revenue and profit milestones as of December 31, 2015. The liability was valued based on 335,891 closing stock price per share of $6.82 on December 31, 2015. The fair value of contingent consideration related to Shopmium was estimated using a Monte Carlo simulation and was based on significant inputs not observable in the market, thus classified as a Level 3 instrument. The inputs include the Company’s stock price, maximum earn-out shares, historical and projected financial results of Shopmium, historical volatility of the Company's stock price and risk-free interest rate. See Note 6 (Acquisitions) The following table represents the change in the contingent consideration (in thousands): Eckim Shopmium Level 3 Level 3 Balance as of December 31, 2014 $ 1,048 $ — Acquisition date fair value measurement — 1,462 Change in fair value 1,243 — Foreign currency translation — (55 ) Transfers out of Level 3 (2,291 ) — Balance as of December 31, 2015 $ — $ 1,407 For the year ended December 31, 2015, the Company recorded a loss of $1.2 million due to the change in fair value of the contingent consideration related to Eckim. The change in fair value of the contingent consideration during the period was primarily driven by Eckim achieving certain revenue and profit milestones, partially offset by the decline in the Company’s common stock price per share. As the contingent consideration relates to Eckim, the liability’s fair value was remeasured with Level 1 inputs by taking the actual number of shares issuable, calculated based on actual revenues and profit achievement, by the Company’s common stock price as of December 31, 2015. Accordingly, the liability was transferred out of Level 3 to Level 1 input category of fair value measurements.

Acquisitions	6. Acquisitions On October 30, 2015, the Company acquired all the outstanding shares of Shopmium S.A. (“Shopmium”), a company based in France, and creator of a mobile app for receipt-scanning and cash-back. The total acquisition consideration of $19.5 million consisted of $16.5 million in cash, 278,639 shares of the Company’s common stock with a fair value of $1.5 million or $5.54 per share, and contingent consideration of up to $4.8 million payable in cash with a fair value of $1.5 million. The contingent consideration payout is based on Shopmium achieving certain revenue and profit milestones for the years ended December 31, 2016 and 2017. At the date of acquisition, the contingent consideration’s fair value of $1.5 million was determined using a Monte Carlo simulation. The Company completed the following business combinations during the year ended December 31, 2014: · On October 10, 2014, the Company entered into an asset purchase agreement with Padopolis, Inc. (“Padopolis”), a digital catalog publishing company. Total purchase price for Padopolis was $1.7 million in cash · On August 4, 2014, the Company entered into an asset purchase agreement with Eckim, a company specializing in search engine performance marketing. The total acquisition consideration of $19.3 million consisted of $12.5 million in cash and up to $6.8 million in contingent consideration. The contingent consideration consists of shares of the Company’s common stock. The contingently issuable shares are contingent on Eckim achieving certain revenue and profit milestones by December 31, 2015. The Company estimated the fair value of the contingent consideration using a Monte Carlo simulation. · On January 2, 2014, the Company acquired all the outstanding shares of Yub, Inc. (“Yub”), a company that allows consumers to link digital offers and promotions to payment cards for savings when they use the cards for in-store purchases. The total acquisition consideration of $10.1 million, which consisted of 1,000,040 shares of the Company’s common stock, was based on the fair value of the Company’s common stock of $10.05 per share. The acquisitions provide the Company with customer and vendor relationships, developed technologies, domain names, patents, registered users, trade names and backlog. The fair values of identifiable intangible assets were determined using discounted cash flow models. The excess of the consideration paid over the fair value of the net tangible assets and identifiable intangible assets acquired is recorded as goodwill. The goodwill is attributable to expected synergies from combined operations and the acquired companies’ knowhow. Assets acquired and liabilities assumed were recorded at their fair values as of the respective acquisition dates. The following table summarizes the consideration paid for each acquisition and the related fair values of the assets acquired and liabilities assumed (in thousands): Acquisition Consideration Net Tangible Assets Acquired/ (Liabilities Assumed) Identifiable Intangible Assets Goodwill Goodwill Deductible for Taxes Acquisition Related Expenses (2) Shopmium $ 19,461 $ (1,383 ) $ 5,803 $ 15,041 Not $ 333 Padopolis 1,700 — 896 804 Deductible 166 Eckim 19,289 — 8,636 10,653 Deductible (1) 288 Yub 10,050 (241 ) 2,320 7,971 Not 376 $ 50,500 $ (1,624 ) $ 17,655 $ 34,469 $ 1,163 (1) Subject to final settlement of the contingent consideration (2) Expensed as general and administrative The following table sets forth each component of identifiable intangible assets acquired in connection with the acquisitions: (in thousands): Shopmium Padopolis Eckim Yub Total Estimated Useful Life (in Years) Developed technologies $ 3,343 $ 596 $ 2,233 $ 692 $ 6,864 5 Customer relationships 1,696 184 4,752 176 6,808 5 Vendor relationships - — — 890 890 4 Domain names 344 116 1,651 487 2,598 5 Registered users 420 — — — 420 4 Patents — — — 75 75 5 Total identifiable intangible assets $ 5,803 $ 896 $ 8,636 $ 2,320 $ 17,655 The financial results of the acquired companies are included in the Company’s consolidated statements of operations from their respective acquisition dates and were insignificant to the Company’s operating results.

Debt Obligations	8. Debt Obligations 2013 Credit and Security Agreement In September 2013, the Company entered into an agreement with a commercial bank to establish an accounts receivable based revolving line of credit. The maximum amount available for borrowing under the revolving credit facility is the lesser of $25.0 million (which can be increased to $30.0 million if certain conditions are met) or an amount equal to 85% of certain eligible accounts, which excludes accounts that are over 60 days outstanding from the original due date. The revolving line of credit has a maturity date of September 30, 2016 and may be repaid and redrawn at any time prior to the maturity date. Interest is charged at a floating interest rate based on the daily three month LIBOR, plus an applicable margin. In May 2014, the Company entered into an amendment, which revised the applicable margin from 2.75% to 2.00% per annum and the financial reporting intervals from monthly to quarterly reporting. As of December 31, 2014, $7.5 million was outstanding under the revolving line of credit. During the year ended December 31, 2015, the Company terminated the line of credit and paid off the balance in full.

Stock-based Compensation 2013 Equity Incentive Plan In October 2013, the Company adopted the 2013 Equity Incentive Plan (the “2013 Plan”), which became effective in March 2014 and serves as the successor to the Company’s 2006 Stock Plan (the “2006 Plan”). Pursuant to the 2013 Plan, 4,000,000 shares of common stock were initially reserved for grant, plus (1) any shares that were reserved and available for issuance under the 2006 Plan at the time the 2013 Plan became effective, and (2) any shares that become available upon forfeiture or repurchase by the Company under the 2006 Plan and 2000 Plan. Under the 2013 Plan, the Company may grant stock options, stock appreciation rights, restricted stock and restricted stock units, performance shares and units to employees, directors and consultants. The shares available will be increased at the beginning of each year by lesser of (i) 4% of outstanding common stock on the last day of the immediately preceding year, or (ii) such number determined by the board of directors. Under the 2013 Plan, both the ISOs and NSOs are granted at a price per share not less than 100% of the fair market value on the effective date of the grant. The board of directors determines the vesting period for each option award on the grant date, and the options generally expire 10 years from the grant date or such shorter term as may be determined by the board of directors. Stock Options The fair value of each option was estimated on the date of grant for the periods presented using the following assumptions: Year Ended December 31, 2015 2014 2013 Expected life (in years) 5.50 to 6.08 6.08 6.08 Risk-free interest rate 1.67% to 1.89% 2.33% 1.09% Volatility 55% to 60% 55% 51% to 53% Dividend yield — — — The weighted-average grant-date fair value of options granted was $5.50, $8.60 and $3.05 per share during the years ended December 31, 2015, 2014 and 2013, respectively. Restricted Stock Units The fair value of RSUs equals the market value of the Company’s common stock on the date of grant. The RSUs are excluded from issued and outstanding shares until they are vested.

Stockholders' Equity (Deficit)	11. Stockholders’ Equity (Deficit) Amended and Restated Certificate of Incorporation In March 2014, the Company filed an amended and restated certificate of incorporation, which became effective immediately following the completion of the Company’s IPO. Under the restated certificate of incorporation, the authorized capital stock consists of 250,000,000 shares of common stock and 10,000,000 shares of preferred stock. Common Stock . The rights, preferences and privileges of the holders of common stock are subject to the rights of the holders of shares of any series of preferred stock which the Company may issue in the future. Subject to the foregoing, for as long as such stock is outstanding, the holders of common stock are entitled to receive ratably any dividends as may be declared by the board of directors out of funds legally available for dividends. Holders of common stock are entitled to one vote per share on any matter to be voted upon by stockholders. The amended and restated certificate of incorporation establishes a classified board of directors that is divided into three classes with staggered three year terms. Only the directors in one class will be subject to election at each annual meeting of stockholders, with the directors in other classes continuing for the remainder of their three year terms. Upon liquidation, dissolution or winding-up, the assets legally available for distribution to the Company’s stockholders would be distributable ratably among the holders of common stock and any participating preferred stock outstanding at that time, subject to prior satisfaction of all outstanding debt and liabilities and the preferential rights of and the payment of liquidation preferences, if any, on any outstanding shares of preferred stock. Preferred Stock . The board of directors is authorized to issue undesignated preferred stock in one or more series without stockholder approval and to determine for each such series of preferred stock the voting powers, designations, preferences, and special rights, qualifications, limitations, or restrictions as permitted by law, in each case without further vote of action by the stockholders. The board of directors can also increase or decrease the number of shares of any series of preferred stock, but not below the number of shares of that series then outstanding, without any further vote or action by the stockholders. The board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of common stock. Amendment . The amendment of the provisions in the restated certificate requires approval by holders of at least 66 2/3% of the Company’s outstanding capital stock entitled to vote generally in the election of directors. Common Stock Subject to Repurchase The Company’s equity plan allows certain employees to exercise options prior to vesting. The Company has the right to repurchase any issued but unvested common shares upon termination of service of an employee, at the original purchase price. The consideration received by the Company upon exercise of an unvested option is considered to be a deposit of the exercise price, and the related dollar amount is recorded as a liability. This liability is reclassified to stockholders’ equity (deficit) on a ratable basis as the award vests. The Company had no liability at December 31, 2015, 2014 and 2013 related to unvested exercised options. Common Stock Repurchases In February 2015, the Company’s Board of Directors authorized the repurchase of up to $50.0 million of the Company’s common stock through February 2016, subject to certain limitations. Stock repurchases may be made from time-to-time in open market transactions or privately negotiated transactions.

The benefit from income taxes for the year ended December 31, 2015 was primarily attributable to a decrease in deferred tax liabilities that arose from a gain the Company recorded from the change in the fair value of contingent consideration related the Eckim acquisition and net foreign tax benefit, partially offset by state income taxes. The provision for income taxes for the year ended December 31, 2014 was primarily attributable to the recognition of deferred tax liabilities that arose from the gain the Company recorded from a change in the fair value of contingent consideration related to the Eckim acquisition. There was no provision or benefit recorded for the year ended December 31, 2013 due to the valuation allowance recorded against substantially all of our deferred tax assets. Undistributed earnings of $0.5 million of the Company’s foreign subsidiaries are considered to be indefinitely reinvested and, accordingly, no provision for federal and state income taxes have been provided thereon. The Company intends to reinvest these earnings indefinitely in its foreign subsidiaries. If these earnings were distributed to the United States in the form of dividends or otherwise or if the shares of the relevant foreign subsidiaries were sold or otherwise transferred, the Company would be subject to additional U.S. income taxes (subject to adjustment for foreign tax credits) and foreign withholding taxes. Determination of the amount of unrecognized deferred income tax liability related to these earnings is not practical. As a result of meeting certain employment and capital investment actions under Section 10AA of the India Income Tax Act, the Company’s India subsidiary qualifies for an income tax holiday, for tax years 2014 through 2019. A portion of these tax incentives will expire at the beginning of 2020. The Company recognizes a benefit from stock-based compensation as additional paid-in capital if an incremental tax benefit is realized by following the with-and-without approach. In addition, the indirect effects of stock-based compensation deductions are not considered in the income tax provision for purposes of measuring the excess tax benefit at settlement of awards. The components of the Company’s deferred tax assets and liabilities are as follows (in thousands): Year Ended December 31, 2015 2014 Deferred tax assets: Credits and net operating loss carryforward $ 73,012 $ 57,524 Accrued compensation 3,197 3,441 Deferred revenues 114 113 Stock based compensation 10,317 9,420 Property and equipment (1,588 ) 906 Other deferred tax assets 1,419 1,605 Total deferred tax assets 86,471 73,009 Valuation allowance (85,835 ) (67,450 ) Deferred tax liabilities: Basis difference on purchased intangible assets 1,526 5,603 Other deferred tax liabilities 1,642 2,123 Total deferred tax liabilities 3,168 7,726 Net deferred tax assets (liabilities) $ (2,532 ) $ (2,167 ) Other deferred tax assets and liabilities are primarily comprised of the tax effects of accounts receivable reserves, sales allowances and change in fair value of contingent consideration. As of December 31, 2015 and 2014, the Company had gross deferred tax assets of $86.5 million and $73.0 million, respectively. The Company also had deferred tax liabilities of $3.2 million and $7.7 million as of December 31, 2015 and 2014, respectively. Realization of the deferred tax assets is dependent upon the generation of future taxable income, if any, the amount and timing of which is uncertain. Based on the available objective evidence, and historical operating performance, management believes that it is more likely than not that all U.S. and certain foreign deferred tax assets are not realizable. Accordingly, the net deferred tax assets have been fully offset with a valuation allowance. The net valuation allowance increased by approximately $18.4 million and $8.6 million for the years ended December 31, 2015 and 2014, respectively. As of December 31, 2015, the Company had federal net operating loss carryforwards of approximately $218.8 million which will begin to expire in 2018. The Company had state net operating loss carryforwards of approximately $212.2 million which will begin to expire in 2016. Federal net operating loss carryforwards of $68.0 million and $55.0 million at December 31, 2015 and 2014, respectively, represent deductions from stock-based compensation for which a benefit would be recorded in additional paid-in capital when it reduces income taxes payable. As of December 31, 2015, the Company has research credit carryforwards for federal income tax purposes of approximately $9.6 million which will begin to expire in the year 2031. The Company also had state net research credit carryforwards for income tax purposes of approximately $9.4 million which can be carried forward indefinitely. A reconciliation of the gross unrecognized tax benefit is as follows (in thousands): Year Ended December 31, 2015 2014 2013 Unrecognized tax benefit - beginning balance $ 1,366 $ 813 $ 285 Increases for tax positions taken in prior years 5,611 553 271 Increases for tax positions taken in current year 1,782 — 257 Unrecognized tax benefit - ending balance $ 8,759 $ 1,366 $ 813 As of December 31, 2015, the Company has unrecognized tax benefits of $5.5 million if realized would not affect the Company’s effective tax rate as these tax benefits would be offset by changes in the Company’s valuation allowance. The Company does not believe there will be any material changes in its unrecognized tax benefits over the next twelve months. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense. As of December 31, 2015 and 2014, the Company had no accrued interest or penalties related to uncertain tax positions. Due to the Company’s historical loss position, all tax years from inception through December 31, 2015 remain open due to unutilized net operating losses. The Company files income tax returns in the United States and various states and foreign jurisdictions and is subject to examination by various taxing authorities including major jurisdiction like the United States. As such, all its net operating loss and research credit carryforwards that may be used in future years are subject to adjustment, if and when utilized. Utilization of the net operating loss carryforwards and credits may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before their utilization.

Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The Company’s consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Actual results may differ from the Company’s estimates, and such differences may be material to the accompanying consolidated financial statements.
Cash, Cash Equivalents and Short-term Investments	Cash, Cash Equivalents and Short-term Investments The Company considers all highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. The Company’s short-term investments consists of certificates of deposits with original maturities of greater than three months and remaining maturities less than one year as of the balance sheet date.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at invoiced amounts and do not bear interest. The Company generally does not require collateral and performs ongoing credit evaluations of its customers and maintains allowances for potential credit losses. The Company maintains an allowance for doubtful accounts based upon the expected collectability of its accounts receivable. The allowance is determined based upon specific account identification
Property and Equipment, Net	Property and Equipment, net Property and equipment, net, are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets, which are three years for computer equipment and software and five years for all other asset categories except leasehold improvements, which are amortized over the shorter of the lease term or the expected useful life of the improvements. Equipment leased under capital leases is amortized over the shorter of the lease term or the asset’s estimated useful life.
Internal-Use Software Development Costs	Internal-Use Software Development Costs C osts incurred for computer software developed or obtained for internal use, the Company begins to capitalize 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. These costs are amortized to cost of revenues over the estimated useful life of the related asset, generally estimated to be three years. Costs incurred prior to meeting these criteria together with costs incurred for training and maintenance are expensed as incurred and recorded in research and development expense on the Company’s consolidated statements of operations.
Leases	Leases Leases meeting certain criteria are accounted for as capital leases. The imputed interest is included in interest expense in the accompanying consolidated statements of operations, and the capitalized value is amortized as part of the Company’s property and equipment, net. Obligations under capital leases are reduced by lease payments, net of imputed interest. All other leases are accounted for as operating leases. When an operating lease contains a predetermined fixed escalation of the minimum rent, or if tenant allowances have been received, the related rent expense is recognized on a straight-line basis over the term of the lease, with the difference between the recognized rent expense and amounts payable under the lease recorded as deferred rent liability.
Business Combinations	Business Combinations The Company accounts for acquisitions of entities that include inputs and processes and have the ability to create outputs as business combinations. Under the acquisition method of accounting, the total consideration is allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition dates. The excess of the consideration transferred over those fair values is recorded as goodwill. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Acquisition related costs are not considered part of the consideration, and are expensed as general and administrative expense as incurred.

Goodwill is tested for impairment at least annually, and more frequently upon the occurrence of certain events. The Company completes its annual impairment test during the fourth quarter of each year. There was no impairment of goodwill for the years ended December 31, 2015, 2014 and 2013.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Long-lived assets are reviewed 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 first 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, an impairment loss would be recognized when the carrying amount of the asset exceeds the fair value of the asset. The Company has not recognized any impairment of long-lived assets for the years ended December 31, 2015, 2014 and 2013.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying values of the Company’s financial instruments, including cash equivalents, accounts receivable, accounts payable, accrued compensation and benefits, and other current liabilities, approximate fair value due to their short-term nature. Debt obligations are stated at the carrying value as the stated interest rates approximate market rates available to the Company. The Company records money market funds, short-term investments and contingent consideration at fair value. See Note 3 (Fair Value Measurements)

Coupons. The Company generates revenues, as consumers select, activate, or redeem a coupon through our platform by either printing it for physical redemption at a retailer or saving it to a retailer loyalty account for automatic digital redemption. In the case of the setup fees, it recognizes revenues proportionally, on a per activation basis, using the number of authorized activations per insertion order, commencing on the date of the first coupon activation. For coupons, the pricing is generally determined on a per unit activation basis. Setup fees charged to customers represent charges for the creation of digital coupons and related activation, tracking and security features. Upfront insertion orders generally include a limit on the number of activations, or times consumers may select a coupon. Coupon Codes . The Company generally generates revenues when a consumer makes a purchase using a coupon code from its platform and completion of the order is reported to the Company.

Digital Media - The Company’s media services enable CPGs and retailers to deliver digital media and advertising to promote their brands and products on the Company’s websites and mobile apps, and through the Company’s affiliate publishers and non-publisher third parties. The Company charges a fee for these media campaigns, the pricing of which is based on the advertisement size and position. Related fees are generally billed monthly, based on a per-campaign, per-impression or per-click basis. The Company does not offer rights of refund of previously paid or delivered amounts, rebates, rights of return or price protection. In all instances, the Company limits the amount of revenue recognized to the amounts for which it have the right to bill its’ customers.
Gross versus Net Revenue Reporting	Gross versus Net Revenue Reporting In the normal course of business and through its distribution network, the Company delivers digital coupons and media on retailers’ websites, through retailers’ loyalty programs, and on the websites of digital publishers. In these situations, the Company generally pays a distribution fee to the retailers or publishers which is included in the Company’s cost of revenues. The determination of whether revenues 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 is the principal or an agent, the Company follows the accounting guidance for principal-agent considerations. Because the Company is the primary obligor and is responsible for (i) fulfilling the digital coupon and media delivery, (ii) establishing the selling prices for delivery of the digital coupons and media, and (iii) performing all billing and collection activities including retaining credit risk, the Company has concluded that it is the principal in these arrangements and therefore the Company reports revenues and cost of revenues on a gross basis.
Multiple-element Arrangements	Multiple-element Arrangements For arrangements with multiple-deliverables, the Company determines whether each of the individual deliverables qualify as a separate unit of accounting. In order to treat deliverables in a multiple element arrangement as a separate unit of accounting, the deliverable must have standalone value upon delivery. The Company allocates the arrangement fee to all the deliverables (separate units of accounting) using the relative selling price method in accordance with the selling price hierarchy, which includes vendor-specific objective evidence (“VSOE”) if available, third-party evidence (“TPE”) if VSOE is not available and best estimate of selling price (“BESP”) if neither VSOE nor TPE is available. VSOE and TPE do currently not exist for any of the Company’s deliverables. Accordingly, for arrangements with multiple deliverables that can be separated into different units of accounting, the Company allocates the arrangement fee to the separate units of accounting based on BESP. 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.
Deferred Revenues	Deferred Revenues Deferred revenues consist of coupon setup fees and activation fees that are expected to be recognized upon coupon activations, which generally occurs within the next twelve months.
Cost of Revenues	Cost of Revenues Cost of revenues consist primarily of distribution fees, third-party data center costs, personnel costs and depreciation and amortization expense. Distribution fees consist of payments to partners within the Company’s network for their digital coupon publishing services. Personnel costs include salaries, bonuses, stock-based awards and employee benefits. The personnel costs are primarily attributable to individuals maintaining the Company’s data centers and operations, which initiate, sets up and deliver digital coupon media campaigns. Depreciation and amortization expense includes depreciation of data center equipment and amortization of capitalized internal use software.
Research and Development Expense	Research and Development Expense The Company expenses the cost of research and development as incurred. Research and development expense consists primarily of personnel and related headcount costs and costs of professional services associated with the ongoing development of the Company’s technology.
Stock-based Compensation	Stock-based Compensation The Company accounts for stock-based compensation using the fair value method, which requires the Company to measure the stock-based compensation based on the grant-date fair value of the awards and recognize the compensation expense over the requisite service period. The Company recognizes compensation expense net of estimated forfeitures. Equity awards issued to nonemployees are recorded at fair value on their measurement date and are subject to adjustment each period as the awards vest. The fair value of RSUs equals the market value of the Company’s common stock on the date of grant. RSUs granted prior to the Company’s IPO have a contractual term of seven years and vest upon the satisfaction of both a service condition and a liquidity-event condition. The service condition is satisfied as to 25% of the RSUs on each of the first four anniversaries of the vesting commencement date. The liquidity-event condition is satisfied upon the earlier of (i) six months after the effective date of the IPO or (ii) March 15 of the calendar year following the year in which the IPO was declared effective; and (iii) the time immediately prior to the consummation of a change in control. The vesting condition that was satisfied six months following the Company’s IPO did not affect the expense attribution period for the RSUs for which the service condition has been met as of the date of the Company’s IPO. This six-month period was not a substantive service condition and, accordingly, beginning on the effectiveness of the Company’s IPO in March 2014, the Company recognized a cumulative stock-based compensation expense for the portion of the RSUs that had met the service condition as of the date of the Company’s IPO. The Company recognized stock-based compensation expense associated with RSUs of $27.7 million and $29.5 million during the years ended December 31, 2015 and 2014, respectively. RSUs granted on or after the Company’s IPO have similar terms as the RSUs granted prior to the Company’s IPO, but are not subject to a liquidity-event condition in order to vest, and the compensation expense is recognized on a straight-line basis over the applicable service period.
Advertising Expense	Advertising Expense Advertising costs are expensed when incurred and are included in sales and marketing expense on the accompanying consolidated statements of operations. The Company incurred $1.4 million, $0.8 million and $1.9 million of advertising costs during the years ended December 31, 2015, 2014 and 2013, respectively. Advertising costs consist primarily of online marketing costs, such as sponsored search, advertising on social networking sites, e-mail marketing campaigns, loyalty programs, and affiliate programs.
Income Taxes	Income Taxes The Company accounts for income taxes in accordance with authoritative guidance, which requires the use of the 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 reverse. A valuation allowance is provided when it is more likely than not that the deferred tax assets will not be realized. In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes The Company recognizes liabilities for uncertain tax positions based upon a two-step process. To the extent a tax position does not meet a more-likely-than-not level of certainty, no benefit is recognized in the consolidated financial statements. If a position meets the more-likely-than-not level of certainty, it is recognized in the consolidated financial statements at the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company accounts for any applicable interest and penalties as a component of income tax expense.
Foreign Currency	Foreign Currency Foreign currency denominated assets and liabilities of foreign subsidiaries, where the local currency is the functional currency, are translated into U.S. Dollars using the exchange rates in effect at the balance sheet dates, and income and expenses are translated using average exchange rates during the period. The resulting foreign currency translation adjustments are recorded in accumulated other comprehensive income (loss), a component of stockholders’ equity. Gains and losses from foreign currency transactions are included in other income (expense), net in the accompanying consolidated statements of operations. Foreign currency transaction gains (losses) were immaterial for all the periods presented in the accompanying consolidated financial statements.
Other Comprehensive Income (Loss)	Other Comprehensive Income (Loss) Other comprehensive income (loss) consists of foreign currency translation adjustments.
Net Loss per Share Attributable to Common Stockholders	Net Loss per Share Attributable to Common Stockholders The Company computes its basic and diluted net loss per share attributable to common stockholders using the two-class method required for companies with participating securities. The Company’s basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, less the weighted average unvested common stock subject to repurchase. The diluted net income per share attributable to common stockholders is computed by giving effect to all potentially dilutive common shares equivalents outstanding during the period. The effects of options to purchase common stock, redeemable convertible preferred stock (outstanding prior to the Company’s IPO in March 2014), RSUs, and common stock warrants are excluded from the computation of diluted net loss per share attributable to common stockholders because their effect is antidilutive.
Segments	Segments The Company’s chief operating decision maker, who is the Chief Executive Officer, reviews the Company’s financial information presented on a consolidated basis for purposes of allocating resources and evaluating our financial performance. There are no segment managers who are held accountable by the chief operating decision maker, or anyone else, for operations, operating results, and planning for levels or components below the consolidated unit level. Accordingly, the Company has determined that it operates in a single reporting segment.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, short-term investments and accounts receivable. For cash, cash equivalents and short-term investments, the Company is exposed to credit risk in the event of default by the financial institutions to the extent of the amounts recorded on the accompanying consolidated balance sheets. Credit risk with respect to accounts receivable is dispersed due to the large number of customers. The Company does not require collateral for accounts receivable.

Loss Contingency, Lawsuit Filing Date	On March 11, 2015, a putative stockholder class action lawsuit was filed against us, the members of our board of directors, certain of our executive officers and the underwriters of our IPO: Nguyen v. Coupons.com Incorporated, Case No. CGC-15-544654 (California Superior Court, San Francisco County). The complaint asserts claims under the Securities Act and seeks unspecified damages and other relief on behalf of a putative class of persons and entities who purchased stock pursuant or traceable to the registration statement and prospectus for our IPO. Plaintiff Nguyen requested and obtained a dismissal without prejudice of his San Francisco action and filed another complaint with substantially the same allegations in the Santa Clara County Superior Court, Nguyen v. Coupons.com Incorporated, Case No. 1-15-CV-278777 (California Superior Court, Santa Clara County) (Mar. 30, 2015). Three other complaints with substantially the same allegations have also been filed: O’Donnell v. Coupons.com Incorporated, Case No. 1-15-CV-278399 (California Superior Court, Santa Clara County) (Mar. 20, 2015); So v. Coupons.com Incorporated, Case No. 1-15-CV-278774 (California Superior Court, Santa Clara County) (Mar. 30, 2015); and Silverberg v. Coupons.com Incorporated, Case No. 1-15-CV-278891 (California Superior Court, Santa Clara County) (Apr. 2, 2015). On May 7, 2015, the Santa Clara court consolidated the Nguyen, So and Silverberg actions with the O’Donnell action.
