Business overview
GoPro, Inc. (GoPro or the Company) was incorporated as Woodman Labs, Inc. in California on February 14, 2004 as an S Corporation and reincorporated in Delaware in December 2011 as a C Corporation. The Company produces mountable and wearable cameras and accessories, which the Company refers to as capture devices. Additionally, GoPro develops and provides desktop editing software and mobile applications for free to consumers. The Company’s capture devices are sold globally through retailers, wholesale distributors and on the Company’s website. The Company has wholly-owned subsidiaries in Hong Kong, Germany and the Cayman Islands. GoPro’s corporate headquarters are located in San Mateo, California with additional operational support offices in Hong Kong, the Netherlands and Shenzhen, China.
In July 2012, the Company’s board of directors (Board) approved a 3-for-1 split of the preferred stock and common stock. All share and per share amounts for all periods presented in these consolidated financial statements have been adjusted to reflect the stock split.
The Company completed its initial public offering (IPO) of Class A common stock on July 1, 2014. The Company sold 8,900,000 shares and certain of its stockholders sold 11,570,000 shares, including 2,670,000 shares for the underwriters' option to purchase additional shares. The shares were sold at an initial public offering price of $24.00 per share for net proceeds of $200.8 million to the Company, after deducting underwriting discounts and commissions of $12.8 million. Offering costs incurred by the Company were approximately $6.2 million.
The Company completed a follow-on offering of common stock in November 2014. The Company sold 1,287,533 shares of Class A common stock and certain of its stockholders sold 10,627,042 shares, including 1,554,075 shares for the underwriters' option to purchase additional shares. The shares were sold at an initial public offering price of $75.00 per share for net proceeds of $93.2 million to the Company, after deducting underwriting discounts and commissions of $3.4 million. Offering costs incurred by the Company were approximately $1.5 million.
Basis of presentation
Basis of presentation
Basis of presentation
The Company’s fiscal year ends on December 31, and its fiscal quarters end on March 31, June 30 and September 30.
Principles of consolidation
These consolidated financial statements include all the accounts of the Company and its wholly-owned subsidiaries. Unless otherwise specified, references to the Company are references to the Company and its consolidated subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation.
 
Use of estimates
The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the amounts reported and disclosed in the Company’s consolidated financial statements and accompanying notes. The Company bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. The actual results experienced by the Company may differ materially and adversely from management’s estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected.
Comprehensive income
For all periods presented, comprehensive income equaled net income. Therefore, the Consolidated Statements of Comprehensive Income have been omitted from the consolidated financial statements.
Summary of significant accounting policies
Summary of significant accounting policies
Summary of significant accounting policies
Cash equivalents
Cash equivalents consist of short-term, highly liquid financial instruments with immaterial interest rate risk that are readily convertible to cash and have maturities of three months or less from the date of purchase. As of December 31, 2014, cash equivalents consisted of money market funds recorded at cost, which approximates fair value and a corporate debt security that was less than 90 days from maturity when acquired, recorded at amortized cost which approximates fair value.
Marketable securities
Marketable securities consist of commercial paper, U.S. treasury securities, U.S. agency securities, and corporate debt securities, and are classified as available-for-sale securities. As the Company views these securities as available to support current operations, it has classified all available-for-sale securities as short-term. Available-for-sale securities are carried at fair value with unrealized gains and losses, if any, reported as a component of accumulated other comprehensive income in stockholders' equity, while realized gains and losses and other-than-temporary impairments, if any, are reported as a component of net income. As of December 31, 2014, the Company's marketable securities were recorded at their amortized cost which approximates fair value. An impairment charge is recorded in the Consolidated Statements of Operations for declines in fair value below the cost of an individual investment that is deemed to be other than temporary. The Company assesses whether a decline in value is temporary based on the length of time that the fair market value has been below cost, the severity of the decline and the intent and ability to hold or sell the investment. The Company did not identify any marketable securities as other-than-temporarily impaired as of December 31, 2014.
Accounts receivable and allowance for doubtful accounts
Accounts receivables are stated at invoice value less estimated allowances for returns and doubtful accounts. The Company continually monitors customer payments and maintains a reserve for estimated losses resulting from its customers’ inability to make required payments. The Company considers factors such as historical experience, credit quality, age of the accounts receivable balances, geographic related risks and economic conditions that may affect a customer’s ability to pay. In cases where there are circumstances that may impair a specific customer’s ability to meet its financial obligations, a specific allowance is recorded against amounts due, and thereby reduces the net recognized receivable to the amount reasonably believed to be collectible. For all periods presented, the activity in the allowance for doubtful accounts was not material.
Inventories
Inventories consist of finished goods and component parts, which are purchased directly or from contract manufacturers. Inventories are stated at the lower of cost or market on a first-in, first-out basis. The Company’s assessment of market value requires the use of estimates regarding the net realizable value of its inventory balances, including an assessment of excess or obsolete inventories. The Company determines excess and obsolete inventories based on an estimate of the future demand for its products within a specified time horizon, generally 12 months. The estimates used for future demand are also used for near-term capacity planning and inventory purchases and are consistent with revenue forecast assumptions. If the Company’s demand forecast is greater than actual demand, the Company may be required to record an excess inventory charge, which would decrease gross profit. Any write-downs taken establish a new cost basis for the underlying inventory. For all periods presented, inventories were predominantly comprised of finished goods.
 
Point of purchase (POP) displays
The Company sponsors a program to provide retailers with POP displays in order to facilitate the marketing of the Company’s products within retail stores. The POP displays contain a video display that broadcast video images taken by GoPro cameras with product placement available on the POP display for cameras and accessories. The Company generally provides these POP displays to customers free of charge. The costs of the POP displays, less any fees charged to customers, are capitalized as a long-term asset on the accompanying Consolidated Balance Sheets, and the net cost is recognized over the expected period of the benefit provided by these assets, which generally ranges from 24 to 36 months.

Property and equipment, net
Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful life of the assets, ranging from one to seven years. Leasehold improvements are stated at cost and amortized over the shorter of the lease term or the expected useful life of the improvements. Property and equipment pending installation, configuration or qualification are classified as construction in progress.
Fair value measurements
The Company categorizes the fair value of its financial assets according to the hierarchy established by the FASB, which prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are:
Level 1
Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to directly access.
Level 2
Valuations based on quoted prices for similar assets or liabilities; valuations for interest-bearing securities based on non-daily quoted prices in active markets; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.
Level 3
Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. In circumstances in which a quoted price in an active market for the identical liability is not available, the Company is required to use the quoted price of the identical liability when traded as an asset, quoted prices for similar liabilities, or quoted prices for similar liabilities when traded as assets. If these quoted prices are not available, the Company is required to use another valuation technique, such as an income approach or a market approach.
Leases
The Company leases its facilities under cancelable and non-cancelable operating leases. For leases that contain rent escalation or rent concession provisions, the Company records the total rent expense on a straight-line basis over the term of the lease. The Company records the difference between the rent paid and the straight-line rent as a deferred rent liability on the accompanying Consolidated Balance Sheets. Leasehold improvements are included in property and equipment, net.
Goodwill, acquired intangible assets and other long-lived assets
Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired in a business combination. Goodwill is not amortized but the Company performs an annual qualitative assessment of its goodwill during the fourth quarter of each calendar year to determine if any events or circumstances exist, such as an adverse change in business climate or a decline in the overall industry demand, that would indicate that it would more likely than not reduce the fair value of a reporting unit below its carrying amount, including goodwill. If events or circumstances do not indicate that the fair value of a reporting unit is below its carrying amount, then goodwill is not considered to be impaired and no further testing is required. If further testing is required, the Company performs a two-step process. The first step involves comparing the fair value of the Company’s reporting unit to its carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the second step of the test is performed by comparing the carrying value of the goodwill in the reporting unit to its implied fair value. An impairment charge is recognized for the excess of the carrying value of goodwill over its implied fair value. For the purpose of impairment testing, the Company has determined that it has one reporting unit. There has been no impairment of goodwill for any periods presented.
The Company’s long-lived assets consist of property and equipment and acquired intangible assets. Acquired intangible assets with definite lives are amortized on a straight-line basis over the remaining estimated economic life of the underlying products and technologies. The Company reviews its definite-lived long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset may not be recoverable. Recoverability of an asset group is measured by comparing its carrying amount to the expected future undiscounted cash flows that the asset group is expected to generate. If it is determined that an asset group is not recoverable, an impairment loss is recorded in the amount by which the carrying amount of the asset group exceeds its fair value. There has been no impairment of long-lived assets for any periods presented.
Warranty
The Company generally provides 12-month warranty coverage on all of its products except in the European Union where the Company provides a two-year warranty. The Company’s warranty provides for repair or replacement of the associated products during the warranty period. The Company establishes a liability for estimated product warranty costs at the time product revenue is recognized. The warranty obligation is affected by product failure rates and the related use of materials, labor costs and freight incurred in correcting any product failure. Should actual product failure rates, use of materials, or other costs differ from the Company’s estimates, additional warranty liabilities could be required, which would reduce its gross profit.
Revenue recognition
Revenue is primarily comprised of product revenue, net of returns and sales incentives.
Revenue is primarily derived from the sale of capture devices, as well as the related implied post contract support (PCS). The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and collectability is reasonably assured. Evidence of an arrangement consists of an order from its distributors, resellers or online customers. The Company considers delivery to have occurred once title and risk of loss has been transferred. Customer deposits are included in accrued liabilities on the accompanying Consolidated Balance Sheets and are recognized as revenue when all the criteria for recognition of revenue are met.
The Company’s standard terms and conditions of sale for its non-web-based sales do not allow for product returns and it generally does not allow product returns other than under warranty. However, the Company grants limited rights to return product for certain large retailers and distributors. Estimates of expected future product returns are recognized at the time of sale based on analyses of historical return trends by customer class. Upon recognition, the Company reduces revenue and cost of sales for the estimated return. Return trends are influenced by product life cycle status, new product introductions, market acceptance of products, sales levels, product sell-through, the type of customer, seasonality, product quality issues, operational policies and procedures, and other factors. Return rates can fluctuate over time, but are sufficiently predictable to allow the Company to estimate expected future product returns.
For customers who purchase products directly from the Company’s website, transfer of risk of loss is determined to be upon delivery to the customer’s address. The Company defers those sales made to customers who purchase products from its website during a fixed time frame prior to the end of the reporting period for which the Company estimates delivery to occur in the following period. The Company uses estimates to determine when shipments are delivered based on third-party metrics for average transit time. Additionally, the Company provides a 30-day money back guarantee for web-based sales for which the Company reduces revenue by an estimate of potential future product returns related to the web-based sales, based on analyses of historical return trends and seasonality. Estimates for web-based sale returns and estimates to derive web sale shipment delivery dates may differ from actual results.
The Company’s camera products include multiple elements. Each element in a multiple element arrangement must be evaluated to determine whether it represents a separate unit of accounting. An element constitutes a separate unit of accounting when it has standalone value and delivery of an undelivered element is both probable and delivery is within the Company’s control.
The Company has determined its multiple element arrangements generally include two separate units of accounting: The first element is the hardware component (camera and accessories) and the embedded firmware essential to the functionality of the camera delivered at the time of sale. The second element is the implied right for the customer to receive post contract support included with the purchase of the Company’s camera products. PCS includes the right to receive, on a when and if available basis, future unspecified firmware upgrades and features as well as bug fixes, email and telephone support.
The Company accounts for each element separately and allocate fees from the arrangement based on the relative selling price of each element. Revenue allocated to an undelivered element is recognized over an estimated service period. The Company recognizes revenue for delivered elements only when all contractual obligations have been completed.
The Company uses a hierarchy to determine the allocation of revenue. The hierarchy is as follows: (i) vendor-specific objective evidence of fair value (VSOE), (ii) third-party evidence of selling price (TPE) and (iii) best estimate of the selling price (BESP).
i.
VSOE generally exists only when a company sells a deliverable separately and is the price actually charged by the company for that deliverable. The Company does not sell its deliverables separately and, as such, do not have VSOE.
ii.
TPE can be substantiated by determining the price that other parties sell similar or substantially similar offerings. The Company does not believe that there is accessible TPE evidence for similar deliverables since there are not comparable deliverables sold by other companies.
iii.
BESP reflects the Company’s best estimates of what the selling prices of elements would be if they were sold regularly on a stand-alone basis. The Company believes that BESP is the most appropriate methodology for determining the allocation of revenue for its multiple element arrangements.
The Company has allocated revenue between its two elements using the relative selling price method which is based on the BESP for all deliverables. Revenue allocated to the delivered hardware and the related essential software is recognized at the time of sale provided the conditions for recognition of revenue have been met. Revenue allocated to PCS is deferred and recognized on a straight-line basis over the estimated term of the support period, which is estimated to be one year based on historical experience. As of December 31, 2014, and 2013, deferred implied PCS revenue was $11.6 million and $6.4 million, respectively.
The Company’s process for determining the BESP for its deliverables involves multiple factors that may vary depending upon the unique facts and circumstances related to each deliverable. Key factors considered by the Company in developing the BESP for PCS include evaluating the level of support provided to customers and analyzing the amount of time and cost that is allocated to the Company’s efforts to develop the undelivered elements, determining the cost of its support efforts, and then adding an appropriate level of gross profit to these costs.
Sales incentives
The Company offers sales incentives through various programs, consisting primarily of cooperative advertising and marketing development fund programs. The Company records cooperative advertising and marketing development fund programs with customers as a reduction to revenue unless it receives an identifiable benefit in exchange for credits claimed by the customer and can reasonably estimate the fair value of the identifiable benefit received, in which case the Company will record it as a marketing expense. In addition, the Company offers price protection discounts to certain customers when new capture device models are released and the customer has remaining inventory on hand of the older capture device model. The Company estimates price protection discounts, which are recorded as a reduction of revenue, by evaluating inventory currently held by the customer subject to price protection. The Company records reductions to revenue for sales incentives when the related revenue is recognized.
Cost of revenue
Cost of revenue includes actual product cost, the cost of shipping, depreciation and amortization, warehousing and processing inventory, warranty replacement costs, excess and obsolete inventory write-downs, certain allocated costs and license fees paid to third parties.
Shipping costs
The Company records amounts billed to customers for shipping costs as revenue in the accompanying Consolidated Statements of Operations. The Company classifies related shipping and handling costs incurred as cost of revenue in the accompanying Consolidated Statements of Operations.
Deferred revenue
Deferred revenue is comprised of customer deposits, undelivered post contract support and undelivered web sale shipments. The cost of revenue related to deferred web sales is included in inventory.
Research and development
Research and development expense includes internal and external costs. Internal costs include employee related expenses, equipment costs, depreciation expense and allocated facility costs. External research and development expenses consist of costs associated with consultants, tooling and prototype materials.
Substantially all research and development expense is related to new research and development efforts and the designing of significant improvements to existing products. Research and development expense to establish the technological feasibility of the Company’s internally developed software is expensed as incurred. To date, the period between achieving technological feasibility and the release of internally developed software to be sold, leased, or marketed has been short and development costs qualifying for capitalization have been insignificant.
Advertising costs
Advertising costs consist of costs associated with print, television and ecommerce media advertisements and are expensed as incurred. A significant amount of the Company’s promotional expenses result from payments under event, resort and athlete sponsorship contracts. Accounting for sponsorship payments is based upon specific contract provisions. These sponsorship arrangements are considered to be executory contracts and, as such, the costs are recognized as performance under the contract is received. The costs associated with preparation of sponsorship activities, including the supply of GoPro products, media team support and activation fees are considered costs of producing advertising and are expensed as incurred. Prepayments made under sponsorship agreements are included in prepaid expenses or other assets depending on the period to which the prepayment applies. Advertising costs were $47.2 million, $55.5 million, and $46.9 million for the years ended December 31, 2014, 2013, and 2012, respectively.
Stock-based compensation
The Company accounts for stock-based compensation activity using the fair value recognition and measurement provisions of GAAP. These provisions require the all share-based payments to employees, including grants of stock options, restricted stock units (RSUs), restricted stock awards (RSAs) and purchases under the Company's Employee Stock Purchase Plan (ESPP), to be measured based on the grant-date fair value of the awards, with the resulting expense generally recognized over the period during which the employee is required to perform service in exchange for the award. The fair value of each stock option granted is estimated using the Black-Scholes option pricing model. The fair value of service-based RSUs and RSAs granted represents the closing price of the Company's common stock on the date of grant. The fair value of stock-based awards with market and service conditions are estimated using a Monte Carlo valuation model. The fair value of purchases under the Company's ESPP is calculated based on the closing price of the Company's common stock on the date of grant. For service-based awards, stock-based compensation is recognized on a straight-line basis over the requisite service period, net of estimated forfeitures. The forfeiture rate is based on an analysis of the Company's actual historical forfeitures. For performance and market-based awards which also require a service period, the Company uses graded vesting over the longer of the derived service period or when the performance or market condition is satisfied.
The Company accounts for stock options and restricted stock issued to nonemployees based on the fair value of the awards determined using the Black-Scholes option pricing model. The fair value of awards granted to nonemployees is re-measured as the awards 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.
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 reflected in the income tax provision for purposes of measuring the excess tax benefit at settlement of awards.
Sales taxes
Sales taxes collected from customers and remitted to respective governmental authorities are not included in revenue and are reflected as a liability on the accompanying Consolidated Balance Sheets.
Foreign currency
The Company and the Company’s wholly-owned subsidiaries use the U.S. dollar as their functional currency. Local currency transactions of the Company’s international operations are remeasured into U.S. dollars at the rates of exchange in effect at the date of the transaction. For those wholly-owned subsidiaries with assets or liabilities denominated in currencies other than the U.S. dollar, non-monetary assets are remeasured into U.S. dollars using historical rates of exchange. Monetary assets and liabilities are remeasured into U.S. dollars using exchange rates prevailing on the balance sheet date. Transaction gains and losses were not material for all periods presented and are included in other expense, net, in the accompanying Consolidated Statements of Operations.
Income taxes
The Company utilizes the asset and liability method of accounting for income taxes which requires the recognition of deferred tax assets and liabilities for expected future consequences of temporary differences between the financial reporting and income tax bases of assets and liabilities using enacted tax rates. Management makes estimates, assumptions and judgments to determine the Company’s provision for income taxes and also for deferred tax assets and liabilities, and any valuation allowances recorded against the Company’s deferred tax assets. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent the Company believes that recovery is not likely, the Company must establish a valuation allowance.
The calculation of the Company’s current provision for income taxes involves the use of estimates, assumptions and judgments while taking into account current tax laws, interpretation of current tax laws and possible outcomes of future tax audits. The Company has established reserves to address potential exposures related to tax positions that could be challenged by tax authorities. Although the Company believes its estimates, assumptions and judgments to be reasonable, any changes in tax law or its interpretation of tax laws and the resolutions of potential tax audits could significantly impact the amounts provided for income taxes in the Company’s consolidated financial statements.
The calculation of the Company’s deferred tax asset balance involves the use of estimates, assumptions and judgments while taking into account estimates of the amounts and type of future taxable income. Actual future operating results and the underlying amount and type of income could differ materially from the Company’s estimates, assumptions and judgments thereby impacting the Company’s financial position and results of operations.
The Company has adopted ASC 740-10 “Accounting for Uncertainty in Income Taxes” that prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of uncertain tax positions taken or expected to be taken in the Company’s income tax return, and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.
The Company includes interest and penalties related to unrecognized tax benefits within income tax expense in the accompanying Consolidated Statements of Operations.
Recent accounting pronouncements
On May 28, 2014, the Financial Accounting Standards Board (FASB) issued a new accounting standard update on revenue from contracts with customers, which supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. The new guidance adheres to the core principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this principle, the new guidance lists five steps that entities should follow, including identifying the contract with a customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations in the contract and recognizing revenue when the entity satisfies a performance obligation. The new guidance becomes effective for the Company on January 1, 2017, with retrospective application permitted. Early application is not permitted. The Company is currently assessing the impact of this new guidance.
In June 2014, the FASB issued a new accounting standard update on the accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period is treated as a performance condition. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The new guidance becomes effective for the Company on January 1, 2016, with early adoption permitted. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial statements.
In August 2014, the FASB issued new guidance related to the disclosures around going concern. The new standard update provides guidance around management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial statements.
Fair value measurements
Fair value measurements
Fair value measurements
The Company measures its cash equivalents and marketable securities at fair value based on an expected exit price as defined by the authoritative guidance on fair value measurements, which represents the amount that would be received on the sale of an asset or paid to transfer a liability, as the case may be, in an orderly transaction between market participants. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis, whereby, inputs used in valuation techniques are assigned a hierarchical level.
The Company’s assets that are measured at fair value on a recurring basis, by level, within the fair value hierarchy as of December 31, 2014 are summarized as follows:

The fair value of the Company's Level 1 financial instruments, which are traded in active markets, are based on quoted market prices for identical instruments. The fair value of the Company's Level 2 fixed income securities are obtained from an independent pricing service, which may use quoted market prices for identical or comparable instruments or model driven valuations using observable market data or inputs corroborated by observable market data. The Company's procedures include controls to ensure that appropriate fair values are recorded, including comparing the fair values obtained from the Company's pricing service against fair values obtained from other independent sources.

Redeemable convertible preferred stock
As of December 31, 2013, there were 36,000,000 shares of Series A preferred stock authorized and 30,523,036 shares of Series A preferred stock issued and outstanding. Concurrent with the close of the IPO in July 2014, all shares of Series A preferred stock were converted into Class B common stock. Prior to their conversion to Class B common stock, the Series A preferred stock had the following terms:
Conversion
Each share of Series A preferred stock was convertible, at the option of the holder, into shares of common stock at a rate of 1-for-1. The conversion of all outstanding Series A preferred stock occurred in connection with the closing of the IPO.
Voting rights
The holders of shares of the Company’s Series A preferred stock voted equally with shares of Class B common stock on an as-if converted to common stock basis on all matters, including the election of directors.
Dividend rights
The holders of each Series A share were entitled to receive any noncumulative dividends on an equal basis with common stock, when and if declared by the Board.
Redemption rights
In the event of any liquidation, dissolution, or winding up of the Company, whether voluntary or involuntary, the Company was required to redeem shares of Series A preferred stock at the original issue price of $2.53 per share plus any noncumulative dividends declared by the Board. If the holders had not previously exercised the rights granted to them, the Series A preferred stock was redeemable within 365 days after July 1, 2017, subject to a majority vote of the then outstanding Series A preferred shares. As the redemption events described above could have occurred and were not solely within the Company’s control, all shares of preferred stock were presented outside of permanent equity.

Preferred stock
Upon completion of its IPO in July 2014, the Company filed a Restated Certificate of Incorporation, which authorized the issuance of undesignated preferred stock with rights and preferences, including voting rights, designated from time to time by its board of directors. As of December 31, 2014, there were 5,000,000 shares of preferred stock authorized, and no shares issued or outstanding.
Common stock
As of December 31, 2014, the Company had 500,000,000 shares of Class A common stock authorized and 150,000,000 shares of Class B common stock authorized. As of December 31, 2014, 52,091,317 shares of Class A stock were issued and outstanding and 77,023,371 shares of Class B stock were issued and outstanding.
In June 2014, the Company filed a Restated Certificate of Incorporation which established two classes of authorized common stock (Reclassification): Class A common stock and Class B common stock. As a result, all outstanding shares of common stock were converted into shares of Class B common stock. The rights of the holders of Class A and Class B common stock are identical, except with respect to voting and conversion. Each share of Class A common stock is entitled to one vote per share and each share of Class B common stock is entitled to ten votes per share. Each share of Class B common stock is convertible at any time at the option of the stockholder into one share of Class A common stock and has no expiration date. The Class B common stock is also convertible into Class A common stock on the same basis upon any transfer, whether or not for value, except for “Permitted Transfers” as defined in the Company’s Restated Certificate of Incorporation. Each share of Class B common stock will convert automatically into one share of Class A common stock upon the date when the outstanding shares of Class B common stock represent less than 10% of the aggregate number of shares of common stock then outstanding.
As of December 31, 2013, the Company had 150,000,000 shares of common stock authorized for issuance. At December 31, 2013, there were 81,420,040 shares of common stock issued and outstanding.
The Company had the following shares of common stock reserved for issuance upon the exercise of equity instruments as of December 31, 2014 (in thousands):

Stock compensation plans
2014 Equity Incentive Plan
In June of 2014, stockholders approved the 2014 Equity Incentive Plan (2014 EIP) and the Company’s authority to grant new awards under the 2010 Equity Incentive Plan (2010 EIP) was terminated. The 2014 EIP provides for equity grants to employees, including executive officers, and non-employee directors and contractors, including stock options, RSUs, RSAs, stock appreciation rights, stock bonuses, and performance awards. Options granted under the 2014 EIP generally expire within 10 years from the date of grant and generally vest over four years, at the rate of 25% on the first anniversary of the date of grant and ratably on a monthly basis over the remaining 36-month period thereafter based on continued service and are exercisable for shares of the Company’s Class A common stock. Options with performance or market-based conditions are generally subject to a required service period along with the performance or market condition. RSUs granted under the 2014 EIP generally vest either annually or quarterly over three or four years based upon on continued service, and are settled upon vesting as shares of the Company’s Class A common stock. All awards that expire, are reacquired or repurchased at cost, are cancelled or otherwise terminate and shares that are withheld to satisfy exercise proceeds and tax withholding obligations are returned to the plan and are available for grant in conjunction with the issuance of new stock awards under the 2014 EIP. Awards settled in cash will not reduce the number of shares available under the 2014 EIP.
As of December 31, 2014 the 2014 EIP permitted the Company to grant up to 13,973,723 shares of the Company’s Class A common stock, which includes 339,259 shares previously reserved as Class B common stock but unissued under the 2010 EIP that became available for issuance as Class A common stock under the 2014 EIP, and 164,235 shares previously issuable pursuant to awards under the 2010 EIP that expired, forfeited or terminated unexercised, or were repurchased or used to pay the exercise price of an option or withheld to satisfy tax withholding obligations, that became available for issuance as Class A common stock under the 2014 EIP. The share reserve may also increase to the extent that outstanding awards under the 2010 EIP expire or terminate unexercised or shares that are repurchased at cost or used to pay the exercise price of an option or withheld to satisfy tax withholding obligations.
2010 Equity Incentive Plan
In August 2010, the Board approved the adoption of the 2010 EIP. The 2010 EIP provided for equity grants to employees, including executive officers, and non-employee directors and contractors that permits the granting of stock options, RSUs, RSAs and stock appreciation rights. Options granted under the 2010 EIP generally expire within 10 years from the date of grant. Options and RSUs granted under the 2010 Plan generally vest over four years based on continued service, and are settled or exercisable upon vesting as shares of the Company’s Class B common stock. Following the Reclassification, all shares subject to the 2010 EIP were reclassified into Class B common stock and all outstanding options under the 2010 EIP will become Class B shares upon exercise. In the second quarter of 2014, the Company terminated the authority to grant new awards under the 2003 Plan.
Employee Stock Purchase Plan
In June 2014, the Company approved the 2014 Employee Stock Purchase Plan (ESPP). The ESPP allows eligible employees to purchase shares of the Company's Class A common stock through payroll deductions at a price equal to 85% of the lower of the fair market values of the stock as of the beginning or the end of six-month offering periods. An employee's payroll deductions under the ESPP are limited to 15% of their eligible compensation and employees may not purchase more than 2,500 shares of stock per offering period. As of December 31, 2014, 3,367,557 shares were reserved for future issuance under the ESPP.

RSAs and early-exercised stock options' activity
RSAs represent share awards of the Company’s common stock that are generally subject to repurchase at the original issuance price upon termination of services prior to vesting. These repurchase terms are considered to be a forfeiture provision and do not result in mark-to-market accounting each reporting period. The Company has also granted options that provide certain option holders the right to exercise unvested options for shares of restricted stock. RSAs and restricted shares issued upon early exercise of stock are legally issued and outstanding, but are only deemed outstanding for basic earnings per share computation purposes upon the lapse of the Company’s right of repurchase. Cash received from option holders for exercise of unvested options is treated as a refundable deposit shown as a liability on the accompanying Consolidated Balance Sheets, and reclassified to Stockholders’ Equity (Deficit) as the Company’s repurchase right lapses.
A summary of the Company’s restricted stock and early-exercised stock options subject to repurchase activity is as follows:

The total fair value of restricted stock and early exercised stock options subject to repurchase vested in the year ended December 31, 2014, 2013, and 2012 was $11.2 million, $6.1 million, and $2.9 million, respectively. As of December 31, 2014, the early exercised stock options were fully vested, and the amount of unearned stock-based compensation related to unvested restricted stock was $0.1 million, with a weighted average remaining vesting term of 0.1 years.
In December 2011, the Company granted 433,500 shares of restricted stock and 210,000 stock options at an exercise price of $1.52 per share to two consultants in accordance with the terms of their service agreements, subject to monthly vesting over a three-year service period and a two-year service period, respectively.
RSU activity
The Company has granted RSUs pursuant to the EIP. RSUs are share awards that, upon vesting, will deliver to the holder shares of the Company’s common stock. Typically, vesting of RSUs is subject to the employee’s continuing service to the Company on the vesting date. The cost of these awards is determined using the fair value of the Company’s common stock on the date of grant, and compensation is recognized on a straight-line basis over the requisite vesting period. The Company has also issued RSUs with both a market condition and a service condition.  The Company estimates the fair value of these market-based RSUs using a Monte Carlo valuation model on the date of grant.
The following table summarizes the activities of the Company’s RSUs:

There were no RSUs awarded during the years ended December 31, 2012 and 2013. As of December 31, 2014, the amount of unearned stock-based compensation estimated to be expensed with respect to RSUs was $94.7 million, and the weighted average remaining vesting term was 2.9 years. The total fair value of RSUs vested during the year ended December 31, 2014 was $28.2 million.
In June of 2014, the Company issued 4,500,000 RSU's to the Chief Executive Officer (CEO RSUs) which included 1,500,000 RSUs that vested immediately upon grant. The balance as of December 31, 2014 included the remaining 3,000,000 unvested RSUs that vest subject to performance criteria set by the Compensation Committee as well as with continued service over a three-year period.
Fair value disclosures
The Company measures compensation expense for all stock-based payment awards, including stock options, RSUs, and RSAs granted to employees and purchases under the Company's ESPP, based on the estimated fair values on the date of the grant. The fair value of stock options granted and purchases under the Company's ESPP is estimated using the Black-Scholes option pricing model.
The Black-Scholes option pricing model requires the following major inputs:
Fair value of common stock. The Company uses the closing price of the Company's common stock on the date of grant. Prior to the Company's IPO which completed in July 2014, the fair value of its common stock was determined by its board of directors, which intended all options granted to be exercisable at a price per share not less than the per share fair value of the common stock underlying those options on the date of grant. The valuations of the Company's common stock were determined in accordance with the guidelines outlined in the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. Upon completion of the Company's initial public offering in July 2014, its Class A common stock was valued by reference to its publicly traded price.
Expected volatility. Expected volatility is a measure of the amount by which the stock price is expected to fluctuate. The Company estimates the expected volatility of its stock options at their grant date by taking the average historical volatility of a group of comparable publicly traded companies over a period equal to the expected life of the options.
Expected term. Expected term represents the period over which the Company anticipates stock-based awards to be outstanding. As the Company has undergone significant operational and structural changes, the historical exercise data do not provide a reasonable basis upon which to estimate expected life. As a result, the Company used the simplified method, as provided under Staff Accounting Bulletin Topic 14.D, “Share-Based Payment,” to calculate the expected term estimate based on the options’ vesting term and contractual terms. Under the simplified method, the expected life is equal to the average of the stock-based award’s weighted average vesting period and its contractual term.
Risk-free interest rate. The risk-free interest rate is the estimated average interest rate based on U.S. Treasury zero-coupon notes with terms consistent with the expected life of the awards.
Expected dividends. Since the Company does not anticipate paying any recurring cash dividends in the foreseeable future, it uses an expected dividend yield of 0% in stock option valuation models.
The fair value of stock options granted was estimated as of the grant date using the assumptions listed in the following table:

Stock-based compensation expense related to the CEO RSUs for the year ended December 31, 2014 was $38.3 million and was included in general and administrative expense in the accompanying Consolidated Statement of Operations.
In October 2013, the Company issued 430,000 shares of restricted stock to two founders of an acquired company, of which 322,500 were subject to monthly vesting over a three-year service period. During the year ended December 31, 2014, vesting was accelerated for 195,740 shares of these shares due to the termination of one of the founders, per the terms of the original award agreements. The Company recorded a charge of $3.2 million to research and development in the accompanying Consolidated Statement of Operations.
Stock option modifications
During the year ended December 31, 2012, the Company modified options to purchase 250,000 shares of common stock of three employees to accelerate vesting and extend the time allowed to exercise the stock options in conjunction with termination of employment. The Company recorded a charge of $1.1 million related to the modification of these awards, of which $1.0 million was recorded to sales and marketing expense and the remaining amounts to research and development and general and administrative expenses based on the employees’ functional role within the Company.
Compensation cost recognized upon employee sale of shares to the Chief Executive Officer (CEO)
In December 2012, eight employees sold 760,500 shares of their common stock for $13.0 million to the Company’s CEO. The stock was sold at $17.08 per share, which was greater than the determined fair value of the common stock at the time of sale. The fair value was determined by the Board, based on the Company’s development and sales efforts, revenue growth, independent third-party valuations and additional objective and subjective factors relating to the Company’s business. The Company determined that the amount paid by the Company’s CEO exceeded the estimated fair value of these shares by $2.6 million and concluded that the value transferred to employees in excess of the fair value of shares sold was additional compensation to the selling employees. As a result, the Company recorded compensation expense of $2.6 million, of which $0.3 million was recorded to research and development, $1.7 million was recorded to sales and marketing and $0.6 million was recorded to general and administrative expense in the accompanying Consolidated Statements of Operations. Of the 760,500 shares sold, the Company's CEO purchased 240,000 shares from two employees who are family members of the Company’s CEO.
Net income per share attributable to common stockholders
Net income per share attributable to common stockholders
Net income per share attributable to common stockholders
Basic and diluted net income per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. Prior to the IPO and their conversion, the Company considered its redeemable convertible preferred stock to be participating securities. In addition, the Company considers shares issued upon the early exercise of options subject to repurchase and non-vested restricted shares to be participating securities, as the holders of these shares have a nonforfeitable right to dividends.
Basic net income (loss) per share attributable to common stockholders is computed by dividing the net income attributable to common stockholders by the weighted-average number of common shares outstanding during the period. All participating securities are excluded from basic weighted average common shares outstanding. Diluted net income (loss) per share attributable to common stockholders is computed by dividing the net income attributable to common stockholders by the weighted-average number of common shares outstanding, including all potentially dilutive common shares, if the effect of each class of potential shares of common stock is dilutive.
The undistributed earnings are allocated based on the contractual participation rights of the Class A and Class B common shares as if the earnings for the year have been distributed. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis. The computation of the diluted net income (loss) per share of Class A common stock assumes the conversion of Class B common stock, while diluted net income (loss) per share of Class B common stock does not assume the conversion of Class A common stock as Class A common stock is not convertible into Class B common stock.

Credit facility
On December 21, 2012, the Company entered into a $170.0 million syndicated senior secured credit facility consisting of a $120.0 million three-year term loan facility and a $50.0 million four-year revolving credit facility. The Company received net proceeds of $127.6 million, net of $2.4 million of debt issuance and lender costs. The debt issuance and lender costs were allocated between the term loan facility and the revolving credit facility based on the maximum lending commitment amounts. The debt issuance costs allocated to the term loan facility were reported as deferred charges and the lender costs allocated to the term loan facility were included in the carrying value of the term loan as debt discount. Borrowings under the credit facility were collateralized by substantially all of the assets of the Company. In August 2014, the Company terminated this credit facility.
As of December 31, 2013, $114.0 million of the term loan was outstanding and the remaining unamortized discount was $0.4 million. The effective interest rate on the term loan was 3.79% on December 31, 2013. The interest rate was based on the 6-month adjusted LIBOR (London Interbank Offered Rate) plus 2.5%. Mandatory additional principal prepayments could have been required based on excess cash flows of the Company. The Company’s excess cash flows, as defined in the credit facility, for 2013 triggered a contractual principal prepayment obligation of $48.5 million, which has been classified as a current liability as of December 31, 2013. Concurrent with the close of the IPO in July 2014, the Company repaid, in full, the term loan outstanding of $108.0 million, and recorded the remaining deferred issuance costs and debt discount of $0.6 million related to the term loan as interest expense.
The revolving credit facility contractually matured on December 21, 2016. As of December 31, 2013, zero of the revolving credit facility had been drawn down and $20.0 million was committed to a standby letter of credit. In April 2014, the $20.0 million standby letter of credit was terminated. In August 2014, the Company terminated the revolving credit facility and recorded the remaining deferred issuance costs of $0.5 million related to the revolving credit facility as interest expense. 
The credit agreement contains customary representations and warranties and customary affirmative and negative covenants applicable to the Company and its restricted subsidiaries, including, among other things, restrictions on indebtedness, liens, investments, mergers, dispositions, prepayment of other indebtedness and dividends and other distributions. The credit agreement contains an acceleration clause for certain events related to the Company’s financial creditworthiness, including a financial covenant that requires the Company to maintain specific consolidated ratios. As of December 31, 2013, the Company was in compliance with all covenants.

Undistributed earnings of $96.2 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.
Income tax expense reconciles to the amount computed by applying the federal statutory rate (35%) to income before income taxes as follows:

Recognition of deferred tax assets is appropriate when realization of such assets is more likely than not. Based upon the weight of available evidence, which includes the Company’s historical operating performance and the U.S. cumulative net profits in prior periods, the Company believes it is more likely than not that deferred tax assets will be realized.
As of December 31, 2014, the Company’s federal and state net operating loss carryforwards for income tax purposes were $0.4 million and $10.1 million, respectively, and state tax credit carryforwards were approximately $6.2 million. All of the Company's federal and state loss carryforwards and $2.6 million of the state tax credit carryforwards will be recorded to additional paid-in capital when realized. If not utilized, the federal and state losses will begin to expire from 2019 to 2034, while the state tax credits may be carried forward indefinitely. If certain substantial changes in the entity's ownership occur, there could be an annual limitation on the amount of the carryforwards that can be utilized.
On December 19, 2014, The Tax Increase Prevention Act of 2014 was signed into law, which retroactively reinstated the federal research tax credit provisions from January 1, 2014 through December 31, 2014. As a result, the Company recognized an income tax benefit of $6.6 million for federal research and development tax credits.
Uncertain income tax positions
The Company has adopted ASC 740-10 “Accounting for Uncertainty in Income Taxes.” ASC 740-10 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of uncertain tax positions taken or expected to be taken in the Company’s income tax return, and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.
The Company’s total amounts of gross unrecognized tax benefits as of December 31, 2014 was $16.6 million, which represented an increase in unrecognized tax benefits by $6.7 million during 2014. If recognized, $15.5 million of these unrecognized tax benefits (net of federal benefit) would be recorded as a reduction of future income tax provision for the year ending December 31, 2014.
A reconciliation of the beginning and ending amount of the unrecognized income tax benefits during the years ended December 31, 2014 and 2013 are as follows:

The Company’s policy is to account for interest and penalties as income tax expense. As of the December 31, 2014, the Company had accrued interest and penalties of approximately $0.2 million related to unrecognized tax benefits. There was no accrued interest or penalties as of December 31, 2013 and 2012.
It is reasonably possible that the total amounts of unrecognized tax benefits will significantly increase within the next 12 months. However, the range of the reasonably possible change cannot be reliably estimated.
The Company files income tax returns in the U.S. and certain non-U.S. jurisdictions. The Company is subject to U.S. federal income tax examination for calendar tax years ending 2012 through 2014, from 2010 through 2014 for state tax purposes, from 2013 through 2014 for Hong Kong and 2014 for the Netherlands. The U.S. federal and U.S. state taxing authorities may choose to audit tax returns for tax years beyond the statute of limitation period due to significant tax attribute carryforwards from prior years, making adjustments only to carryforward attributes.
The Company is currently under examination by the California Franchise Tax Board for the 2011 and 2012 tax years. At this time, the Company is not able to estimate the potential impact that the examination may have on income tax expense. If the examination is resolved unfavorably, it may have a material negative impact on the Company's results of operations. During 2014, the Company completed an audit by the Internal Revenue Service for the 2011 tax year which included a partial year S corporation and partial year C corporation return. The resolution of this examination did not have a material impact on income tax expense.

Legal proceedings
From time to time, the Company is involved in legal proceedings in the ordinary course of business. The Company believes that the outcome of any existing litigation, either individually or in the aggregate, will not have a material impact on the results of operations, financial condition or cash flows of the Company.
Indemnifications
The Company has entered into indemnification agreements with its directors and executive officers which requires it to indemnify its directors and executive officers against liabilities that may arise by reason of their status or service. In addition, in the normal course of business, the Company enters into agreements that contain a variety of representations and warranties and provide for general indemnification. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future, but have not yet been made. To date, the Company has not paid any claims or been required to defend any action related to its indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations.

In March 2014, the Company modified its Retirement Plan to include an employer matching contribution. The matching contribution was retroactive to January 1, 2014. The matching contribution from the Company is equal to the employee’s 401(k) deferral up to 4% of their 401(k) eligible compensation per pay period.

Concentrations of risk and segment information
Segment information
The Company operates as one operating segment as it reports financial information on an aggregate and consolidated basis to its CEO, who is the Company's chief operating decision maker.
Customer concentration
Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of trade receivables. The Company believes that the credit risk in its trade receivables is mitigated by the Company’s credit evaluation process, relatively short collection terms and dispersion of its customer base. The Company generally does not require collateral and losses on trade receivables have historically been within management’s expectations.
As of December 31, 2014 and 2013, the Company had the following customers who represented 10% or more of its net accounts receivable balance:

Supplier concentration
The Company relies on third parties for the supply and manufacture of its capture devices. In instances where a supply and manufacture agreement does not exist or suppliers fail to perform their obligations, the Company may be unable to find alternative suppliers or satisfactorily deliver its products to its customers on time, if at all.
The Company also relies on third parties with whom it outsources supply chain activities related to inventory warehousing, order fulfillment, distribution and other direct sales logistics. The Company cannot provide assurance that these parties will perform their obligations per the contractual terms or that any cost savings, or other benefits will be derived from the efforts of these parties. If any of these parties breaches or terminates their agreement with the Company or otherwise fails to perform their obligations in a timely manner, the Company’s financial results may be adversely affected.

Revenue in the United States, which is included in the Americas geographic region, was $796.0 million, $498.5 million and $278.7 million for the years ended December 31, 2014, 2013 and 2012, respectively. During the year ended December 31, 2014, the Company reclassified four countries it had previously included in the APAC geographical region to now be included in the EMEA geographical region. This caused $19.3 million, $10.6 million and $3.6 million of revenue to be reclassified from the APAC region to the EMEA region.
As of December 31, 2014 and 2013 long-lived assets, which represent property and equipment, located outside the United States, primarily China, were $25.4 million and $6.0 million, respectively.
The Company does not disclose revenue by product category as it does not track sales incentives and other revenue adjustments by product category to report such data.

Acquisitions
On October 18, 2013, the Company completed the acquisition of 100% of the shares of General Things, a leading digital design and software studio based in San Francisco, California for aggregate acquisition consideration of $17.0 million, comprised of $10.0 million of cash and $7.0 million related to 430,000 shares of the Company’s common stock. The cash consideration includes retention bonuses of $1.7 million and the shares of the Company’s common stock includes 322,500 unvested stock awards. The acquisition is expected to advance the Company’s business back-end and consumer-facing web development.
Of the aggregate acquisition consideration, approximately $10.1 million was determined to be the accounting purchase price attributable to the portion of cash and common stock for which there is no remaining requisite service period. The Company expects to record $6.9 million as compensation expense over the requisite service periods following the acquisition.
The Company also recorded acquisition-related transaction costs of $0.3 million, which were included in general and administrative expenses during the year ended December 31, 2013.
The Company has calculated the fair value of the tangible and intangible assets acquired to allocate the purchase price as of the acquisition date. The excess of purchase price over the aggregate fair values was recognized as goodwill. The purchase price of the transaction was allocated as follows:

The fair value of the intangible asset was determined using the income approach with significant inputs that are not observable in the market. Key assumptions included expected future cash flows and discount rates consistent with the assessment of risk. The purchased intangible asset will be amortized using a straight-line amortization method over its estimated useful lives. Among the factors that contributed to a purchase price in excess of the fair value of the net tangible and intangible assets were the synergies in products that can be leveraged by the Company and the acquisition of an assembled workforce of experienced software engineers.
The results of operations of General Things are included in the accompanying Consolidated Statements of Operations from the date of acquisition. Pro forma results of operations for the General Things acquisition have not been presented because they are not material to the Company’s consolidated financial statements.
Basis of presentation (Policies)
Principles of consolidation
These consolidated financial statements include all the accounts of the Company and its wholly-owned subsidiaries. Unless otherwise specified, references to the Company are references to the Company and its consolidated subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation.
Use of estimates
The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the amounts reported and disclosed in the Company’s consolidated financial statements and accompanying notes. The Company bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. The actual results experienced by the Company may differ materially and adversely from management’s estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected.
Comprehensive income
Cash equivalents
Cash equivalents consist of short-term, highly liquid financial instruments with immaterial interest rate risk that are readily convertible to cash and have maturities of three months or less from the date of purchase.
Marketable securities
Marketable securities consist of commercial paper, U.S. treasury securities, U.S. agency securities, and corporate debt securities, and are classified as available-for-sale securities. As the Company views these securities as available to support current operations, it has classified all available-for-sale securities as short-term. Available-for-sale securities are carried at fair value with unrealized gains and losses, if any, reported as a component of accumulated other comprehensive income in stockholders' equity, while realized gains and losses and other-than-temporary impairments, if any, are reported as a component of net income. As of December 31, 2014, the Company's marketable securities were recorded at their amortized cost which approximates fair value. An impairment charge is recorded in the Consolidated Statements of Operations for declines in fair value below the cost of an individual investment that is deemed to be other than temporary. The Company assesses whether a decline in value is temporary based on the length of time that the fair market value has been below cost, the severity of the decline and the intent and ability to hold or sell the investment.
Accounts receivable and allowance for doubtful accounts
Accounts receivables are stated at invoice value less estimated allowances for returns and doubtful accounts. The Company continually monitors customer payments and maintains a reserve for estimated losses resulting from its customers’ inability to make required payments. The Company considers factors such as historical experience, credit quality, age of the accounts receivable balances, geographic related risks and economic conditions that may affect a customer’s ability to pay. In cases where there are circumstances that may impair a specific customer’s ability to meet its financial obligations, a specific allowance is recorded against amounts due, and thereby reduces the net recognized receivable to the amount reasonably believed to be collectible.
Inventories
Inventories consist of finished goods and component parts, which are purchased directly or from contract manufacturers. Inventories are stated at the lower of cost or market on a first-in, first-out basis. The Company’s assessment of market value requires the use of estimates regarding the net realizable value of its inventory balances, including an assessment of excess or obsolete inventories. The Company determines excess and obsolete inventories based on an estimate of the future demand for its products within a specified time horizon, generally 12 months. The estimates used for future demand are also used for near-term capacity planning and inventory purchases and are consistent with revenue forecast assumptions. If the Company’s demand forecast is greater than actual demand, the Company may be required to record an excess inventory charge, which would decrease gross profit. Any write-downs taken establish a new cost basis for the underlying inventory.
Point of purchase (POP) displays
The Company sponsors a program to provide retailers with POP displays in order to facilitate the marketing of the Company’s products within retail stores. The POP displays contain a video display that broadcast video images taken by GoPro cameras with product placement available on the POP display for cameras and accessories. The Company generally provides these POP displays to customers free of charge. The costs of the POP displays, less any fees charged to customers, are capitalized as a long-term asset on the accompanying Consolidated Balance Sheets, and the net cost is recognized over the expected period of the benefit provided by these assets, which generally ranges from 24 to 36 months.
Property and equipment, net
Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful life of the assets, ranging from one to seven years. Leasehold improvements are stated at cost and amortized over the shorter of the lease term or the expected useful life of the improvements. Property and equipment pending installation, configuration or qualification are classified as construction in progress.
Fair value measurements
The Company categorizes the fair value of its financial assets according to the hierarchy established by the FASB, which prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are:
Level 1
Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to directly access.
Level 2
Valuations based on quoted prices for similar assets or liabilities; valuations for interest-bearing securities based on non-daily quoted prices in active markets; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.
Level 3
Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. In circumstances in which a quoted price in an active market for the identical liability is not available, the Company is required to use the quoted price of the identical liability when traded as an asset, quoted prices for similar liabilities, or quoted prices for similar liabilities when traded as assets. If these quoted prices are not available, the Company is required to use another valuation technique, such as an income approach or a market approach.
Leases
The Company leases its facilities under cancelable and non-cancelable operating leases. For leases that contain rent escalation or rent concession provisions, the Company records the total rent expense on a straight-line basis over the term of the lease. The Company records the difference between the rent paid and the straight-line rent as a deferred rent liability on the accompanying Consolidated Balance Sheets. Leasehold improvements are included in property and equipment, net.
Goodwill, acquired intangible assets and other long-lived assets
Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired in a business combination. Goodwill is not amortized but the Company performs an annual qualitative assessment of its goodwill during the fourth quarter of each calendar year to determine if any events or circumstances exist, such as an adverse change in business climate or a decline in the overall industry demand, that would indicate that it would more likely than not reduce the fair value of a reporting unit below its carrying amount, including goodwill. If events or circumstances do not indicate that the fair value of a reporting unit is below its carrying amount, then goodwill is not considered to be impaired and no further testing is required. If further testing is required, the Company performs a two-step process. The first step involves comparing the fair value of the Company’s reporting unit to its carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the second step of the test is performed by comparing the carrying value of the goodwill in the reporting unit to its implied fair value. An impairment charge is recognized for the excess of the carrying value of goodwill over its implied fair value. For the purpose of impairment testing, the Company has determined that it has one reporting unit. There has been no impairment of goodwill for any periods presented.
The Company’s long-lived assets consist of property and equipment and acquired intangible assets. Acquired intangible assets with definite lives are amortized on a straight-line basis over the remaining estimated economic life of the underlying products and technologies. The Company reviews its definite-lived long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset may not be recoverable. Recoverability of an asset group is measured by comparing its carrying amount to the expected future undiscounted cash flows that the asset group is expected to generate. If it is determined that an asset group is not recoverable, an impairment loss is recorded in the amount by which the carrying amount of the asset group exceeds its fair value.
Warranty
The Company generally provides 12-month warranty coverage on all of its products except in the European Union where the Company provides a two-year warranty. The Company’s warranty provides for repair or replacement of the associated products during the warranty period. The Company establishes a liability for estimated product warranty costs at the time product revenue is recognized. The warranty obligation is affected by product failure rates and the related use of materials, labor costs and freight incurred in correcting any product failure. Should actual product failure rates, use of materials, or other costs differ from the Company’s estimates, additional warranty liabilities could be required, which would reduce its gross profit.
Revenue recognition
Revenue is primarily comprised of product revenue, net of returns and sales incentives.
Revenue is primarily derived from the sale of capture devices, as well as the related implied post contract support (PCS). The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and collectability is reasonably assured. Evidence of an arrangement consists of an order from its distributors, resellers or online customers. The Company considers delivery to have occurred once title and risk of loss has been transferred. Customer deposits are included in accrued liabilities on the accompanying Consolidated Balance Sheets and are recognized as revenue when all the criteria for recognition of revenue are met.
The Company’s standard terms and conditions of sale for its non-web-based sales do not allow for product returns and it generally does not allow product returns other than under warranty. However, the Company grants limited rights to return product for certain large retailers and distributors. Estimates of expected future product returns are recognized at the time of sale based on analyses of historical return trends by customer class. Upon recognition, the Company reduces revenue and cost of sales for the estimated return. Return trends are influenced by product life cycle status, new product introductions, market acceptance of products, sales levels, product sell-through, the type of customer, seasonality, product quality issues, operational policies and procedures, and other factors. Return rates can fluctuate over time, but are sufficiently predictable to allow the Company to estimate expected future product returns.
For customers who purchase products directly from the Company’s website, transfer of risk of loss is determined to be upon delivery to the customer’s address. The Company defers those sales made to customers who purchase products from its website during a fixed time frame prior to the end of the reporting period for which the Company estimates delivery to occur in the following period. The Company uses estimates to determine when shipments are delivered based on third-party metrics for average transit time. Additionally, the Company provides a 30-day money back guarantee for web-based sales for which the Company reduces revenue by an estimate of potential future product returns related to the web-based sales, based on analyses of historical return trends and seasonality. Estimates for web-based sale returns and estimates to derive web sale shipment delivery dates may differ from actual results.
The Company’s camera products include multiple elements. Each element in a multiple element arrangement must be evaluated to determine whether it represents a separate unit of accounting. An element constitutes a separate unit of accounting when it has standalone value and delivery of an undelivered element is both probable and delivery is within the Company’s control.
The Company has determined its multiple element arrangements generally include two separate units of accounting: The first element is the hardware component (camera and accessories) and the embedded firmware essential to the functionality of the camera delivered at the time of sale. The second element is the implied right for the customer to receive post contract support included with the purchase of the Company’s camera products. PCS includes the right to receive, on a when and if available basis, future unspecified firmware upgrades and features as well as bug fixes, email and telephone support.
The Company accounts for each element separately and allocate fees from the arrangement based on the relative selling price of each element. Revenue allocated to an undelivered element is recognized over an estimated service period. The Company recognizes revenue for delivered elements only when all contractual obligations have been completed.
The Company uses a hierarchy to determine the allocation of revenue. The hierarchy is as follows: (i) vendor-specific objective evidence of fair value (VSOE), (ii) third-party evidence of selling price (TPE) and (iii) best estimate of the selling price (BESP).
i.
VSOE generally exists only when a company sells a deliverable separately and is the price actually charged by the company for that deliverable. The Company does not sell its deliverables separately and, as such, do not have VSOE.
ii.
TPE can be substantiated by determining the price that other parties sell similar or substantially similar offerings. The Company does not believe that there is accessible TPE evidence for similar deliverables since there are not comparable deliverables sold by other companies.
iii.
BESP reflects the Company’s best estimates of what the selling prices of elements would be if they were sold regularly on a stand-alone basis. The Company believes that BESP is the most appropriate methodology for determining the allocation of revenue for its multiple element arrangements.
The Company has allocated revenue between its two elements using the relative selling price method which is based on the BESP for all deliverables. Revenue allocated to the delivered hardware and the related essential software is recognized at the time of sale provided the conditions for recognition of revenue have been met. Revenue allocated to PCS is deferred and recognized on a straight-line basis over the estimated term of the support period, which is estimated to be one year based on historical experience. As of December 31, 2014, and 2013, deferred implied PCS revenue was $11.6 million and $6.4 million, respectively.
The Company’s process for determining the BESP for its deliverables involves multiple factors that may vary depending upon the unique facts and circumstances related to each deliverable. Key factors considered by the Company in developing the BESP for PCS include evaluating the level of support provided to customers and analyzing the amount of time and cost that is allocated to the Company’s efforts to develop the undelivered elements, determining the cost of its support efforts, and then adding an appropriate level of gross profit to these costs.
Sales incentives
The Company offers sales incentives through various programs, consisting primarily of cooperative advertising and marketing development fund programs. The Company records cooperative advertising and marketing development fund programs with customers as a reduction to revenue unless it receives an identifiable benefit in exchange for credits claimed by the customer and can reasonably estimate the fair value of the identifiable benefit received, in which case the Company will record it as a marketing expense. In addition, the Company offers price protection discounts to certain customers when new capture device models are released and the customer has remaining inventory on hand of the older capture device model. The Company estimates price protection discounts, which are recorded as a reduction of revenue, by evaluating inventory currently held by the customer subject to price protection. The Company records reductions to revenue for sales incentives when the related revenue is recognized.
Cost of revenue
Cost of revenue includes actual product cost, the cost of shipping, depreciation and amortization, warehousing and processing inventory, warranty replacement costs, excess and obsolete inventory write-downs, certain allocated costs and license fees paid to third parties.
Shipping costs
The Company records amounts billed to customers for shipping costs as revenue in the accompanying Consolidated Statements of Operations. The Company classifies related shipping and handling costs incurred as cost of revenue in the accompanying Consolidated Statements of Operations.
Deferred revenue
Deferred revenue is comprised of customer deposits, undelivered post contract support and undelivered web sale shipments. The cost of revenue related to deferred web sales is included in inventory.
Research and development
Research and development expense includes internal and external costs. Internal costs include employee related expenses, equipment costs, depreciation expense and allocated facility costs. External research and development expenses consist of costs associated with consultants, tooling and prototype materials.
Substantially all research and development expense is related to new research and development efforts and the designing of significant improvements to existing products. Research and development expense to establish the technological feasibility of the Company’s internally developed software is expensed as incurred.
Advertising costs
Advertising costs consist of costs associated with print, television and ecommerce media advertisements and are expensed as incurred. A significant amount of the Company’s promotional expenses result from payments under event, resort and athlete sponsorship contracts. Accounting for sponsorship payments is based upon specific contract provisions. These sponsorship arrangements are considered to be executory contracts and, as such, the costs are recognized as performance under the contract is received. The costs associated with preparation of sponsorship activities, including the supply of GoPro products, media team support and activation fees are considered costs of producing advertising and are expensed as incurred. Prepayments made under sponsorship agreements are included in prepaid expenses or other assets depending on the period to which the prepayment applies.
Stock-based compensation
The Company accounts for stock-based compensation activity using the fair value recognition and measurement provisions of GAAP. These provisions require the all share-based payments to employees, including grants of stock options, restricted stock units (RSUs), restricted stock awards (RSAs) and purchases under the Company's Employee Stock Purchase Plan (ESPP), to be measured based on the grant-date fair value of the awards, with the resulting expense generally recognized over the period during which the employee is required to perform service in exchange for the award. The fair value of each stock option granted is estimated using the Black-Scholes option pricing model. The fair value of service-based RSUs and RSAs granted represents the closing price of the Company's common stock on the date of grant. The fair value of stock-based awards with market and service conditions are estimated using a Monte Carlo valuation model. The fair value of purchases under the Company's ESPP is calculated based on the closing price of the Company's common stock on the date of grant. For service-based awards, stock-based compensation is recognized on a straight-line basis over the requisite service period, net of estimated forfeitures. The forfeiture rate is based on an analysis of the Company's actual historical forfeitures. For performance and market-based awards which also require a service period, the Company uses graded vesting over the longer of the derived service period or when the performance or market condition is satisfied.
The Company accounts for stock options and restricted stock issued to nonemployees based on the fair value of the awards determined using the Black-Scholes option pricing model. The fair value of awards granted to nonemployees is re-measured as the awards 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.
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 reflected in the income tax provision for purposes of measuring the excess tax benefit at settlement of awards.
Sales taxes
Sales taxes collected from customers and remitted to respective governmental authorities are not included in revenue and are reflected as a liability on the accompanying Consolidated Balance Sheets.
Foreign currency
The Company and the Company’s wholly-owned subsidiaries use the U.S. dollar as their functional currency. Local currency transactions of the Company’s international operations are remeasured into U.S. dollars at the rates of exchange in effect at the date of the transaction. For those wholly-owned subsidiaries with assets or liabilities denominated in currencies other than the U.S. dollar, non-monetary assets are remeasured into U.S. dollars using historical rates of exchange. Monetary assets and liabilities are remeasured into U.S. dollars using exchange rates prevailing on the balance sheet date.
Income taxes
The Company utilizes the asset and liability method of accounting for income taxes which requires the recognition of deferred tax assets and liabilities for expected future consequences of temporary differences between the financial reporting and income tax bases of assets and liabilities using enacted tax rates. Management makes estimates, assumptions and judgments to determine the Company’s provision for income taxes and also for deferred tax assets and liabilities, and any valuation allowances recorded against the Company’s deferred tax assets. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent the Company believes that recovery is not likely, the Company must establish a valuation allowance.
The calculation of the Company’s current provision for income taxes involves the use of estimates, assumptions and judgments while taking into account current tax laws, interpretation of current tax laws and possible outcomes of future tax audits. The Company has established reserves to address potential exposures related to tax positions that could be challenged by tax authorities. Although the Company believes its estimates, assumptions and judgments to be reasonable, any changes in tax law or its interpretation of tax laws and the resolutions of potential tax audits could significantly impact the amounts provided for income taxes in the Company’s consolidated financial statements.
The calculation of the Company’s deferred tax asset balance involves the use of estimates, assumptions and judgments while taking into account estimates of the amounts and type of future taxable income. Actual future operating results and the underlying amount and type of income could differ materially from the Company’s estimates, assumptions and judgments thereby impacting the Company’s financial position and results of operations.
The Company has adopted ASC 740-10 “Accounting for Uncertainty in Income Taxes” that prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of uncertain tax positions taken or expected to be taken in the Company’s income tax return, and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.
The Company includes interest and penalties related to unrecognized tax benefits within income tax expense in the accompanying Consolidated Statements of Operations.
Recent accounting pronouncements
On May 28, 2014, the Financial Accounting Standards Board (FASB) issued a new accounting standard update on revenue from contracts with customers, which supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. The new guidance adheres to the core principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this principle, the new guidance lists five steps that entities should follow, including identifying the contract with a customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations in the contract and recognizing revenue when the entity satisfies a performance obligation. The new guidance becomes effective for the Company on January 1, 2017, with retrospective application permitted. Early application is not permitted. The Company is currently assessing the impact of this new guidance.
In June 2014, the FASB issued a new accounting standard update on the accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period is treated as a performance condition. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The new guidance becomes effective for the Company on January 1, 2016, with early adoption permitted. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial statements.
In August 2014, the FASB issued new guidance related to the disclosures around going concern. The new standard update provides guidance around management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial statements.
