Basis of Presentation
Basis of Presentation and Summary of Significant Accounting Policies
Basis of presentation and Summary of Significant Accounting Policies
The Company’s fiscal year ends on December 31, and its fiscal quarters end on March 31, June 30 and September 30.
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary to present fairly the financial position of the Company and its results of operations and cash flows for the interim periods presented have been included. Operating results for the nine months ended September 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014, for any other interim period or for any other future year.
The condensed consolidated balance sheet at December 31, 2013 has been derived from the audited financial statements at that date, but does not include all of the disclosures required by GAAP. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s prospectus filed pursuant to Rule 424(b) under the Securities Act with the Securities and Exchange Commission (SEC) on June 26, 2014.
There have been no significant changes in the Company’s accounting policies from those disclosed in its prospectus filed with the SEC on June 26, 2014, other than the cash equivalents policy described below.
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 September 30, 2014, cash equivalents consisted of money market funds and are stated at cost, which approximates fair value.
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 GoPro, Inc. 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 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 regularly evaluates estimates and assumptions related to its allowance for doubtful accounts, stock-based compensation, inventory valuation, warranty liabilities, sales returns, web-based sale deliveries at period-end, implied post contract support and marketing allowances, the valuation and useful life evaluation of acquired intangibles, the valuation of deferred income tax assets and uncertain tax positions. 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.
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 condensed 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 condensed consolidated financial statements.
Correction of error
During the preparation of the condensed consolidated financial statements for the period ended June 30, 2014, the Company determined that within the consolidated statement of cash flows previously disclosed for the quarter ended March 31, 2014, net cash provided by operating activities was understated by $3.2 million and net cash used for investing activities was understated by the same amount. The Company has properly presented its condensed consolidated statement of cash flows for the nine months ended September 30, 2014 and determined that this revision is not material to prior periods.

Fair Value Measurements
Fair Value Measurements
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.

As of September 30, 2014, the Company’s financial assets included only money market funds of $86.0 million, which were included in cash and cash equivalents on the accompanying condensed consolidated balance sheets. These marketable securities are measured at fair value in active markets on a recurring basis and are classified within Level 1 of the fair value hierarchy. As of September 30, 2014, the Company had no financial assets or liabilities that were classified within Level 2 and Level 3, and had not elected the fair value option for any financial assets and liabilities for which such an election would have been permitted. During the nine months ended September 30, 2014, the Company had no transfers of financial assets between Level 1 and Level 2.
Redeemable Convertible Preferred Stock
Redeemable Convertible Preferred Stock
Redeemable convertible preferred stock
At 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, respectively. Concurrent with the close of the IPO on July 1, 2014, all shares of Series A preferred stock were converted into shares of Class B common stock. Prior to the conversion to Class B common stock, and after giving effect to the Reclassification (defined in Note 6 below), 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 Class B 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 Company's 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 Class B 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 of Directors of the Company (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.
On December 19, 2012, certain Series A stockholders exercised their conversion right and converted 4,211,303 shares of Series A preferred stock to common stock to participate in a common share sale transaction between the Company’s principal stockholder and a new investor pursuant to the pre-existing tag-along right. On December 20, 2012, the Series A preferred stock was modified to eliminate an 8% cumulative dividend and to extend the redemption date to July 2017. The 8% cumulative dividend had been accreted using the effective interest method from the time of issue through February 28, 2016, until the 8% cumulative dividend was eliminated on December 20, 2012. The Company recorded preferred stock dividend accretion of $4.2 million and $3.4 million in the years ended December 31, 2012 and 2011, respectively. On December 21, 2012, a dividend of $1.05 per share was declared and paid to holders of common and preferred stock totaling $117.4 million. The dividend payment to the preferred stockholders represented a settlement of accumulated dividends to date, prepayments of future cumulative dividends and participation in additional dividends paid to common stockholders as contractually provided for. The cash dividend was reflected first as a reduction to preferred stock to the extent that such dividend payments were accreted, with any cash paid in excess of this amount recorded as a reduction of retained earnings until exhausted, then as a reduction of additional paid-in-capital until exhausted, and then as accumulated deficit.

Preferred Stock
Upon completion of its IPO on July 1, 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 the Board. As of September 30, 2014 there were 5,000,000 shares of preferred stock authorized, and no shares of preferred stock issued or outstanding.
Common stock
As of December 31, 2013, the Company had 150,000,000 shares of common stock authorized for issuance and 81,420,040 shares issued and outstanding. On June 20, 2014, the Company filed a Restated Certificate of Incorporation to establish two classes of authorized common stock (Reclassification): Class A common stock and Class B common stock. As a result of the Reclassification, all outstanding shares of common stock were converted into shares of Class B common stock. As of September 30, 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 September 30, 2014, 26,292,404 shares of Class A common stock were issued and outstanding and 99,484,734 shares of Class B common stock were issued and outstanding.

Equity incentive plans
2010 Equity Incentive Plan
In August 2010, the Board approved the adoption of the 2010 Equity Incentive Plan (2010 EIP). As amended, the 2010 EIP permitted the Company to grant up to 40,920,000 shares of the Company’s common stock. The 2010 EIP provided for the grant of incentive and nonqualified stock options, restricted stock, restricted stock units (RSUs) and stock appreciation rights to employees, non-employee directors and consultants of the Company. All shares that were cancelled, forfeited or expired in accordance with the terms of the 2010 EIP were returned to the plan and became available for grant in conjunction with the issuance of new stock awards. Following the Reclassification, all shares subject to the 2010 EIP were converted into Class B common stock. The 2010 EIP terminated with the establishment of the 2014 Equity Incentive Plan (2014 EIP), and no further grants were issued out of the 2010 EIP following termination, though outstanding awards under the 2010 EIP at the time of the plan’s termination remained outstanding in accordance with their terms.
2014 Equity Incentive Plan
In June 2014, the Board approved the adoption of the 2014 EIP, which became effective on June 26, 2014. As of September 30, 2014, the 2014 EIP permits the Company to grant up to 13,921,880 shares of the Company’s Class A common stock, which includes 451,651 shares of Class B common stock previously reserved but unissued under the 2010 EIP 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.
The 2014 EIP will terminate in 2024, unless sooner terminated by the Board. The 2014 EIP provides for the grant of incentive and nonqualified stock options, restricted stock, RSUs, stock appreciation rights and performance awards to employees, non-employee directors and consultants of the Company. All shares that are cancelled, forfeited or expired are returned to the 2014 EIP and are available for grant in conjunction with the issuance of new stock awards.
The Board oversees the administration of the Company’s equity plans and generally determines eligibility, vesting schedules and other terms for awards granted under the plans. Stock options under the 2014 EIP have a maximum contractual term of not more than ten years from the date of grant and are generally exercisable upon vesting. Vesting generally occurs over four years and becomes exercisable 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. Awards that provide for early exercise are subject to repurchase upon the termination of services prior to vesting. The exercise price of stock options must generally be at least 100% of the fair value of the Company’s Class A common stock based on the closing price of the shares on the date of grant.
Employee Stock Purchase Plan
Concurrent with the effectiveness of the Company’s registration statement on Form S-1 on June 26, 2014, the Company’s 2014 Employee Stock Purchase Plan (ESPP) became effective. The ESPP allows eligible employees to purchase shares of the Company’s Class A common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to any plan limitations. The ESPP generally provides for six-month offering periods, and at the end of each offering period, employees are able to purchase shares at 85% of the lower of the fair market value of the Company’s Class A common stock on the first trading day of the offering period or on the last day of the offering period.

The amount of unearned stock-based compensation currently estimated to be expensed with respect to unvested employee options at December 31, 2013 and September 30, 2014 was $22.8 million and $58.5 million, respectively. As of December 31, 2013 and September 30, 2014, the weighted-average period over which the unearned stock-based compensation is expected to be recognized was 1.0 year and 3.4 years, respectively. If there are any modifications or cancellations of the underlying unvested awards, the Company may be required to accelerate, increase or cancel any remaining unearned stock-based compensation expense. Future stock-based compensation expense will increase to the extent that the Company grants additional equity awards or assumes unvested equity awards in connection with acquisitions.
Restricted stock
The Company granted restricted stock pursuant to the 2010 EIP. Restricted stock are share awards that, upon grant, the holder receives restricted shares of the Company’s Class B common stock, 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. Restricted stock is legally issued and outstanding. However, restricted stock is only deemed outstanding for basic earnings per share computation purposes upon the lapse of the Company’s right of repurchase.
Early exercised stock options subject to repurchase
The Company granted options that provide the right to exercise unvested options for shares of restricted stock pursuant to the 2010 EIP. Restricted shares issued upon early exercise of stock options are legally issued and outstanding. However, these restricted shares 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 condensed consolidated balance sheets, and reclassified to stockholders’ equity (deficit) as the Company’s repurchase right lapses.

The weighted average remaining vesting term for the restricted stock and unvested early-exercised stock options subject to repurchase as of December 31, 2013 and September 30, 2014 was 1.4 years and 1.1 years, respectively. The amount of unearned stock-based compensation currently estimated to be expensed with respect to unvested restricted stock and early-exercised stock options at December 31, 2013 and September 30, 2014 was $7.4 million and $8.0 million, respectively. The total fair value of vested restricted stock and early exercised stock options subject to repurchase was $0.9 million and $2.6 million in the three months ended September 30, 2013 and September 30, 2014, respectively, and $2.7 million and $3.1 million in the nine months ended September 30, 2013 and September 30, 2014 respectively.
Restricted stock units
RSUs are share awards that, upon vesting, will deliver to the holder shares of the Company’s Class A common stock under the 2014 EIP or Class B common stock under the 2010 EIP. Typically, vesting of RSUs is subject to the employee’s continuing service to the Company. 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 also issues 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 balance as of September 30, 2014 included 3 million RSUs subject to a market condition. These RSUs were issued to the CEO in the second quarter of fiscal 2014 and can be earned ratably over a period of three years, subject to the achievement of certain market condition milestones that were set by the Compensation Committee.

The amount of unearned stock-based compensation currently estimated to be expensed with respect to RSUs at December 31, 2013 and September 30, 2014 was $4.7 million and $56.2 million, respectively. The total fair value of RSUs vested in the three and nine months ended September 30, 2014 was $0.9 million and $28.5 million, respectively.
Sharing of proceeds from sale of securities
During the development stage of the Company, the founder and CEO entered into a verbal agreement with an employee to share 10% of any proceeds from the sale of equity securities held by the founder and CEO. As a result of the issuance of preferred stock to common stockholders in February 2011, and subsequent sale of these preferred shares by the founder and CEO to third parties, an obligation under this verbal agreement arose. In order to satisfy this obligation and any future obligations that may have arisen out of this verbal agreement, the Company entered into a written agreement and provided the following forms of compensation to the employee:

•
In March 2011, the Company paid the employee $6.1 million in cash, which was recorded as compensation expense within sales and marketing expense. Also in March 2011, the CEO reimbursed the Company for $6.1 million, which was recorded as a stockholder contribution to additional paid-in capital;
•
In June 2011, the Company issued the employee an option to purchase 6,584,427 shares of common stock at an exercise price of $0.763 per share. The option vested immediately and has a contractual life of 10 years. Stock compensation expense of $6.8 million was recorded in June 2011 within sales and marketing expense as a result of this grant. Upon exercise of this option by the employee, the founder and CEO will contribute an equal number of common shares back to the Company. In June 2014, the employee exercised the option to purchase 665,443 shares, for which the CEO contributed the same number of shares back to the Company; and
•
In December 2011, the Company issued the employee 270,000 RSUs that vest upon a change in control of the Company.

Income tax benefit for the three months ended September 30, 2014 was $2.9 million compared to a tax benefit of $1.3 million for the three months ended September 30, 2013 primarily due to lower cumulative U.S. pre-tax income and lower foreign withholding taxes during the three months ended September 30, 2014.
Income tax expense for the nine months ended September 30, 2014 was $2.6 million compared to $6.1 million for the nine months ended September 30, 2013 primarily due to lower U.S. pre-tax income, higher earnings in jurisdictions with lower tax rates than the U.S. and lower foreign withholding tax.
Net Income (Loss) per Share Attributable to Common Stockholders
Net Income (loss) per Share Attributable to Common Stockholders
Net income (loss) per share attributable to common stockholders
Basic and diluted net income (loss) per common share is presented in conformity with the two-class method required for participating securities. The Company considers its redeemable convertible preferred stock to be participating securities. In June 2014, the Company filed a Restated Certificate of Incorporation which established two classes of authorized common stock: 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.
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.
The following table presents the calculations of basic and diluted net income (loss) per share attributable to Class A and Class B common stockholders:

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. The remaining unamortized discount was $0.4 million as of December 31, 2013. The effective interest rate on the term loan was 3.79% on December 31, 2013. 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 amount has been classified as a current liability as of December 31, 2013. Concurrent with the close of the IPO on July 1, 2014, the Company repaid, in full, the term loan outstanding of $108.0 million. The Company recorded the remaining deferred issuance costs and debt discount of $0.6 million related to the term loan as interest expense during the three months ended September 30, 2014.
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 of the revolving credit facility 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 remaining deferred issuance costs of $0.5 million related to the revolving credit facility as interest expense during the three months ended September 30, 2014.
The credit agreement contained customary representations and warranties and customary affirmative and negative covenants applicable to the Company and its restricted subsidiaries. As of December 31, 2013, the Company was in compliance with all covenants.

Concentrations of risk and segment information

Segment information
The Company operates as one operating segment as it only 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.
Customers with accounts receivable equal to or greater than 10% of total accounts receivable as of December 31, 2013 and September 30, 2014 were as follows:

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 be sure that these parties will perform their obligations as expected 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.

Basis of Presentation (Policies)
Basis of accounting 
The Company’s fiscal year ends on December 31, and its fiscal quarters end on March 31, June 30 and September 30.
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary to present fairly the financial position of the Company and its results of operations and cash flows for the interim periods presented have been included. Operating results for the nine months ended September 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014, for any other interim period or for any other future year.
The condensed consolidated balance sheet at December 31, 2013 has been derived from the audited financial statements at that date, but does not include all of the disclosures required by GAAP. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s prospectus filed pursuant to Rule 424(b) under the Securities Act with the Securities and Exchange Commission (SEC) on June 26, 2014.
There have been no significant changes in the Company’s accounting policies from those disclosed in its prospectus filed with the SEC on June 26, 2014, other than the cash equivalents policy described below.
Principles of consolidation 
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 GoPro, Inc. and its consolidated subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation.
Use of estimates 
Use of estimates
The preparation of financial statements in accordance with 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 regularly evaluates estimates and assumptions related to its allowance for doubtful accounts, stock-based compensation, inventory valuation, warranty liabilities, sales returns, web-based sale deliveries at period-end, implied post contract support and marketing allowances, the valuation and useful life evaluation of acquired intangibles, the valuation of deferred income tax assets and uncertain tax positions. 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.
Recent accounting pronouncements 
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 condensed 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 condensed consolidated financial statements.
Cash and Cash Equivalents, Policy [Policy Text Block]
