Basis of presentation and summary of significant accounting policies
Basis of presentation and summary of significant accounting policies
Basis of presentation and summary of significant accounting policies
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and in accordance with the interim period reporting requirements of Form 10-Q. The unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) that management believes are necessary for the fair presentation of the Company's financial condition, results of operations, and cash flows for the periods presented, but are not necessarily indicative of the results expected for the full fiscal year or any other future period. The condensed consolidated balance sheet at December 31, 2014 has been derived from the audited financial statements at that date, but does not include all of the disclosures required by GAAP. This quarterly report should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2014 (2014 Annual Report). There have been no significant changes in the Company’s accounting policies from those disclosed in the footnotes to the audited financial statements contained in its 2014 Annual Report.
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 in 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 condensed consolidated financial statements and accompanying notes. The Company regularly evaluates estimates and assumptions in several areas, including those related to: revenue recognition and related estimates (including sales returns, web-based sale deliveries at period-end, implied post contract support, and marketing allowances), collectability of accounts receivable, stock-based compensation, inventory valuation, product warranty liabilities, the valuation and useful lives of intangible assets and property and equipment, goodwill, and income taxes. 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. Actual results could differ materially from management's estimates. To the extent there are material differences between the estimates and the actual results, future results of operations could be affected.
Comprehensive income
For all periods presented, comprehensive income equaled net income. Therefore, the condensed consolidated statements of comprehensive income have been omitted from the condensed consolidated financial statements.
Recent accounting pronouncements
In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers, which amends the existing accounting standards for revenue recognition. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount to which an entity expects to be entitled when products and services are transferred to customers. ASU 2014-09 was originally to be effective for the Company on January 1, 2017. In July 2015, the FASB affirmed a one-year deferral of the effective date of the new revenue standard. The new standard will become effective for the Company on January 1, 2018 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. Early application is permitted but not before the original effective date of annual periods beginning after December 15, 2016. The Company is currently evaluating the impact the adoption of ASU 2014-09 will have on the Company's consolidated financial statements.
Prior period reclassifications
Reclassifications of certain prior period amounts in the condensed consolidated financial statements have been made to conform to the current period presentation.

Acquisitions and acquired intangible assets and goodwill
During the six months ended June 30, 2015, the Company completed several acquisitions for an aggregate cash consideration of $59.3 million that were accounted for as business combinations. These acquisitions were not material to the Company's condensed consolidated financial statements, either individually or in the aggregate, and therefore actual and proforma disclosures under the applicable accounting guidance have not been presented.

(1) Included in “cash and cash equivalents” in the accompanying condensed consolidated balance sheets as of June 30, 2015 and December 31, 2014, in addition to cash of $331.6 million and $237.0 million, respectively.
The Company classifies its cash equivalents and marketable securities as Level 1 or Level 2 within the fair value hierarchy. The fair value of Level 1 financial instruments, which are traded in active markets, is based on quoted market prices for identical instruments. The fair value of Level 2 financial instruments is 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. At June 30, 2015 and December 31, 2014, the Company had no financial assets or liabilities that were classified as Level 3, which are valued based on inputs supported by little or no market activity.
At June 30, 2015 and December 31, 2014, the amortized cost of the Company's cash equivalents and marketable securities approximated their fair value and there were no material unrealized gains/(losses) either individually or in total.
During the six months ended June 30, 2015, the Company had no transfers of financial assets between levels. At June 30, 2015, $116.7 million of the Company's marketable securities had a contractual maturity of one year or less and $62.3 million had a contractual maturity of one to two years.

Equity incentive plans
The Company has outstanding equity grants from its three stock-based employee compensation plans: the 2014 Equity Incentive Plan (2014 Plan), the 2010 Equity Incentive Plan (2010 Plan), and the Employee Stock Purchase Plan (ESPP). No shares have been issued under the 2010 Plan since June 2014. The 2014 Plan provides for the granting of incentive and nonqualified stock options, restricted stock awards (RSAs), restricted stock units (RSUs), stock appreciation rights, stock bonus awards, and performance awards to employees, non-employee directors, and consultants. Options granted under the 2014 Plan generally expire within 10 years from the date of grant and generally vest over four years. 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 Plan generally vest either annually or quarterly over three or four years based upon on continued service. 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. For additional information regarding the Company's equity incentive plans, please refer to the footnotes to the audited financial statements contained in its 2014 Annual Report.

At June 30, 2015, there was $61.9 million of unearned stock-based compensation expense related to unvested options, which is expected to be amortized over a weighted average period of 2.46 years.
Restricted stock units
The cost of RSUs 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 service period. The Company also has issued RSUs with both a market condition and service condition. The Company estimated the fair value of these market-based RSUs using a Monte Carlo valuation model on the date of grant. A summary of the Company’s RSU activity is as follows:

In June 2014, the Company granted an award of 4.5 million RSUs to the Chief Executive Officer (CEO RSUs), which included 1.5 million RSUs that vested immediately upon grant and 3.0 million RSUs that were subject to a market-based condition and a service condition. In January 2015, the market-based condition was achieved and the Company recorded stock-based compensation expense of $6.0 million and $21.8 million during the three and six months ended June 30, 2015.  At June 30, 2015, $14.5 million of total unearned compensation costs related to the CEO RSUs is expected to be recognized over the remaining vesting period of 2.0 years.
At June 30, 2015, there was $72.0 million of unearned stock-based compensation related to RSUs (including the CEO RSUs), which is expected to be amortized over a weighted average period of 2.27 years.

In the second quarter of 2015, the CEO contributed an aggregate 4,858,180 shares of Class B common stock to the Company without consideration per the terms of a Contribution Agreement dated December 28, 2011, and amended on May 11, 2015.  Under the original Contribution Agreement, the CEO agreed to contribute back to the Company from time to time the same number of shares of common stock as are issued to a certain Company employee upon the exercise of certain stock options held by such employee.  Pursuant to this agreement, the CEO contributed back to the Company 180,000 shares of Class B common stock in April 2015.  In May 2015, the CEO contributed back to the Company 4,678,180 shares of Class B common stock pursuant to the amended agreement, representing all of the then remaining shares subject to the contribution obligations. All of the shares contributed by the CEO were subsequently retired during the three months ended June 30, 2015.
Employee stock purchase plan
On February 13, 2015, a purchase under the Company's ESPP was made and employees purchased an aggregate of 313,233 shares at a price of $20.40 per share. During the three and six months ended June 30, 2015, the Company recorded $0.9 million and $1.9 million of stock-based compensation expense related to the ESPP. At June 30, 2015, there was $0.5 million of unearned stock-based compensation related to the Company’s ESPP, which is expected to be recognized over 0.12 years.
Stock-based compensation expense
The Company measures compensation expense for all stock-based payment awards, including stock options, RSUs, 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. There have been no significant changes in the Company’s valuation assumptions for measuring compensation expense from those disclosed in the footnotes to the audited financial statements contained in its 2014 Annual Report.

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 shares issued upon the early exercise of options subject to repurchase and non-vested restricted shares to be participating securities, because holders of such shares have a non-forfeitable right to dividends. Additionally, prior to the date of the Company's initial public offering (IPO) in June 2014, the Company considered its redeemable convertible preferred stock to be participating securities due to their non-cumulative dividend rights. Immediately after the completion of the Company's IPO, all outstanding shares of redeemable convertible preferred stock converted to 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. 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. Class A common stock is not convertible into Class B common stock.
Basic net income (loss) per share attributable to common stockholders is computed by dividing the net income (loss) 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 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.
Undistributed earnings are allocated based on the contractual participation rights of 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.

The Company's tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items arising in that quarter. In each quarter, the Company updates its estimate of the annual effective tax rate, and if the estimated annual tax rate changes, the Company makes a cumulative adjustment in that quarter.

The Company’s income tax expense was $11.2 million and $1.6 million for the three months ended June 30, 2015 and 2014, respectively, and $14.5 million and $5.5 million for the six months ended June 30, 2015 and 2014, respectively. The Company’s provision for income taxes in each period has differed from the tax computed at the U.S. federal statutory income tax rate due to state taxes, the effect of non-U.S. operations, deductible and non-deductible stock-based compensation expense, non-deductible acquisition-related costs, tax credits and adjustments to unrecognized tax benefits. The higher income tax expense for the three and six months ended June 30, 2015, compared to the same periods in 2014, was primarily due to higher worldwide pre-tax income. The negative tax rates for the same periods in 2014 were primarily attributable to the impact of net losses that are not benefited, foreign withholding taxes, and non-deductible stock based compensation offset, in part, by research tax credits.
The Company is currently under examination by the U.S. Internal Revenue Service for tax years 2012 and 2013. 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 also currently under examination by the California Franchise Tax Board for tax years 2011 and 2012. At this time, the Company is not able to estimate the potential impact that these examinations may have on income tax expense. If the examinations are resolved unfavorably, they may have a material negative impact on the Company's results of operations.
At June 30, 2015 and December 31, 2014, the Company’s total amount of gross unrecognized tax benefits was $17.7 million and $16.6 million, respectively. If recognized, $17.7 million of the unrecognized tax benefits (net of federal benefit) at June 30, 2015 would be recorded as a reduction of the income tax provision in future periods. Management believes events that could occur in the next 12 months and cause a material change in unrecognized tax benefits include, but are not limited to, the completion of examinations by the U.S. or foreign taxing authorities, and the expiration of statute of limitations on the Company's tax returns. The calculation of unrecognized tax benefits involves dealing with uncertainties in the application of complex global tax regulations. Management regularly assesses the Company's tax positions in light of legislative, bilateral tax treaty, regulatory and judicial developments in the countries in which it does business. 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.

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 credit risk in its accounts receivable 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.

Supplier concentration
The Company relies on third parties for the supply and manufacture of its capture devices, some of which are sole-source suppliers.  The Company believes that outsourcing manufacturing enables greater scale and flexibility. As demand and product lines change, the Company periodically evaluates the need and advisability of adding manufacturers to support its operations.  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.

Revenue in the United States, which is included in the Americas geographic region, was $189.1 million and $132.7 million for the three months ended June 30, 2015 and 2014, respectively, and $344.4 million and $243.3 million for the six months ended June 30, 2015 and 2014, respectively. During the three months 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 $8.3 million of revenue to be reclassified from the APAC region to the EMEA region for the six months ended June 30, 2014. 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.
As of June 30, 2015 and December 31, 2014, long-lived assets, which represent gross property and equipment, located outside the United States, primarily in China, were $43.5 million and $25.4 million, respectively.
Basis of presentation and summary of significant accounting policies (Policies)
Basis of accounting 
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and in accordance with the interim period reporting requirements of Form 10-Q. The unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) that management believes are necessary for the fair presentation of the Company's financial condition, results of operations, and cash flows for the periods presented, but are not necessarily indicative of the results expected for the full fiscal year or any other future period. The condensed consolidated balance sheet at December 31, 2014 has been derived from the audited financial statements at that date, but does not include all of the disclosures required by GAAP. This quarterly report should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2014 (2014 Annual Report). There have been no significant changes in the Company’s accounting policies from those disclosed in the footnotes to the audited financial statements contained in its 2014 Annual Report.
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 in 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 condensed consolidated financial statements and accompanying notes. The Company regularly evaluates estimates and assumptions in several areas, including those related to: revenue recognition and related estimates (including sales returns, web-based sale deliveries at period-end, implied post contract support, and marketing allowances), collectability of accounts receivable, stock-based compensation, inventory valuation, product warranty liabilities, the valuation and useful lives of intangible assets and property and equipment, goodwill, and income taxes. 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. Actual results could differ materially from management's estimates. To the extent there are material differences between the estimates and the actual results, future results of operations could be affected.
Comprehensive income 
Comprehensive income
For all periods presented, comprehensive income equaled net income. Therefore, the condensed consolidated statements of comprehensive income have been omitted from the condensed consolidated financial statements.
Recent accounting pronouncements 
Recent accounting pronouncements
In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers, which amends the existing accounting standards for revenue recognition. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount to which an entity expects to be entitled when products and services are transferred to customers. ASU 2014-09 was originally to be effective for the Company on January 1, 2017. In July 2015, the FASB affirmed a one-year deferral of the effective date of the new revenue standard. The new standard will become effective for the Company on January 1, 2018 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. Early application is permitted but not before the original effective date of annual periods beginning after December 15, 2016. The Company is currently evaluating the impact the adoption of ASU 2014-09 will have on the Company's consolidated financial statements.
Prior period reclassifications
