Basis of presentation
Summary of business and significant accounting policies
Summary of business and significant accounting policies
GoPro, Inc. (GoPro or the Company) makes mountable and wearable cameras and accessories. The Company’s products are sold globally through retailers, wholesale distributors and on the Company’s website. The Company's global corporate headquarters are located in San Mateo, California.
Basis of presentation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). The Company's fiscal year ends on December 31, and its fiscal quarters end on March 31, June 30, and September 30. The condensed consolidated financial statements reflect all adjustments (which are normal and recurring in nature) that management believes are necessary for the fair presentation of its financial statements, 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, 2015 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 on Form 10-Q should be read in conjunction with the Company's Annual Report on Form 10-K (Annual Report) for the year ended December 31, 2015. There have been no significant changes in the Company’s accounting policies from those disclosed in its Annual Report.
Principles of consolidation. These condensed 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. Significant estimates and assumptions made by management include those related to: revenue recognition (including sales returns, web-based sale deliveries at period-end, implied post contract support and marketing allowances), stock-based compensation, inventory valuation, product warranty liabilities, the valuation and useful lives of long-lived assets (property and equipment, goodwill and intangibles) 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 approximated net income. Therefore, the condensed consolidated statements of comprehensive income have been omitted from the condensed 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.

Description
 
Date of adoption
 
Effect on the financial statements or other significant matters
Standards that are not yet adopted
 
 
 
 
Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606)
 
This standard 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. In August 2015, the FASB deferred the effective date by one year while providing the option to adopt the standard on the original effective date of January 1, 2017. In March 2016, the FASB issued additional guidance regarding principal versus agent considerations in the accounting of revenue. The standard may be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption.
 
January 1, 2018
 
The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements and related disclosures.
ASU No. 2016-02, Leases (Topic 842)
 
This standard requires lessees to put most leases on their balance sheets but recognize the expenses on their income statements in a manner similar to current practice. Lessees would recognize a right-to-use asset and lease liability for all leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The new standard should be applied on a modified retrospective basis.
 
January 1, 2019
 
The Company is beginning to evaluate the impact that the adoption of this standard will have on its consolidated financial statements.
ASU No. 2016-09, Stock Compensation (Topic 718)
 
This standard requires income tax effects of awards to be recognized in the income statement when the awards vest or are settled, allowing an employer to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting, and to make a policy election to account for forfeitures as they occur. Early adoption is permitted for an entity in any interim or annual period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period.
 
January 1, 2017
 
The Company is beginning to evaluate the impact that the adoption of this standard will have on its consolidated financial statements.
Standards that were adopted
 
 
 
 
ASU No. 2015-03 and ASU 2015-15, Interest - Imputation of Interest (Subtopic 835-30)

 
ASU 2015-03 requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with debt discounts.
ASU 2015-15 was issued to provide clarification to ASU 2015-03 in that fees related to line-of-credit arrangements should continue to be presented as an asset and subsequently amortized ratably over the term of the line-of-credit arrangement.
 
January 1, 2016
 
The adoption of this standard did not have a material impact on the consolidated financial statements. At March 31, 2016, the Company presented debt issuance costs of $3.3 million related to its secured revolving credit facility as an asset on its consolidated balance sheet.
Acquisitions
Acquisitions
Acquisitions
On March 9, 2016, the Company completed its acquisition of a privately-held mobile editing application company for cash consideration of approximately $45 million. The preliminary purchase price allocation primarily included approximately $7.3 million of identifiable intangible assets and approximately $37.5 million of residual goodwill, based on the best estimates of management. Changes to amounts recorded as assets or liabilities resulting from finalizing the purchase price allocation may result in a corresponding adjustment to goodwill. Goodwill is primarily attributable to expected synergies in the technologies that can be leveraged by the Company in future software offerings. Goodwill is not expected to be deductible for U.S. income tax purposes. The operating results of the acquired company have been included in the Company's consolidated financial statements for the three months ended March 31, 2016 from the date of acquisition.
On April 11, 2016, the Company completed its acquisition of a privately-held mobile editing application company for cash consideration of approximately $59 million. The Company is currently determining the fair value of assets acquired and liabilities assumed necessary to develop the purchase price allocation. The Company expects to provide disclosure of the purchase price allocation in its quarterly report on Form 10-Q for the second quarter of 2016.
The acquired companies are headquartered in Austin, Texas and Paris, France. In addition to the amounts above, aggregate deferred cash and stock compensation of up to approximately $37 million is payable to certain continuing employees subject to specified future employment conditions. This amount is expected to be recognized as compensation expense over the requisite service periods of up to four years from the respective acquisition dates.
Actual and pro forma results of operations for these acquisitions have not been presented because they do not have a material impact to the Company's consolidated results of operations, either individually or in aggregate.

(1) Included in “cash and cash equivalents” in the accompanying condensed consolidated balance sheets as of March 31, 2016 and December 31, 2015. Cash balances were $191.9 million and $228.6 million as of March 31, 2016 and December 31, 2015, respectively.
Cash equivalents and marketable securities are classified as Level 1 or Level 2 because the Company uses quoted market prices or alternative pricing sources and models utilizing market observable inputs to determine their fair value. At March 31, 2016 and December 31, 2015, 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. During the three months ended March 31, 2016, the Company had no transfers of financial assets between levels.

Financing Arrangements
In March 2016, the Company entered into a Credit Agreement (Credit Agreement) with JPMorgan Chase Bank, N.A., as administrative agent, Wells Fargo Bank, National Association, as co-agent, and the lender parties thereto. The Credit Agreement provides for a secured revolving credit facility (Credit Facility) under which the Company may borrow up to an aggregate of $250 million and the Company and lenders may increase the total commitments under the Credit Facility to up to $300 million, subject to certain conditions. The Credit Facility will terminate, and all outstanding borrowings become due and payable, in March 2021.
The amount that may be borrowed under the Credit Facility is based upon a borrowing base formula with respect to the Company’s inventory and accounts receivable balances. Borrowed funds accrue interest, at the Company’s election, based on an annual rate of (a) London Interbank Offered Rate (LIBOR) or (b) the administrative agent’s base rate, plus an applicable margin of between 1.50% and 2.00% for LIBOR rate loans, and between 0.50% and 1.00% for base rate loans, depending on the level of utilization of the Credit Facility. The Company is required to pay a commitment fee on the unused portion of the Credit Facility of 0.25% or 0.375% per annum, based on the level of utilization of the Credit Facility. Amounts owing under the Credit Agreement and related credit documents are guaranteed by the Company and its material subsidiaries. The Company and its U.S., Cayman and Netherlands subsidiaries have also granted security interests in substantially all of their assets to collateralize these obligations.
The Credit Agreement contains customary affirmative covenants, such as financial statement reporting requirements and delivery of borrowing base certificates, as well as customary covenants that limit the ability of the Company and its subsidiaries to, among other things, pay dividends, incur debt, create liens and encumbrances, make investments and redeem or repurchase stock. The Company is required to maintain a minimum fixed charge coverage ratio if and when the unborrowed availability under the Credit Facility is less than the greater of $25.0 million or 10.0% of the borrowing base at such time. The Credit Agreement contains customary events of default, such as the failure to pay obligations when due, initiation of bankruptcy or insolvency proceedings, defaults on certain other indebtedness, change of control or breach of representations and warranties or covenants. Upon an event of default, the lenders may, subject to customary cure rights, require the immediate payment of all amounts outstanding and foreclose on collateral.
No borrowings have been made from the Credit Facility to date. As of March 31, 2016, the Company was in compliance with all financial covenants contained in the Credit Agreement.

Stock repurchase program
On September 30, 2015, the Company's board of directors authorized a program to repurchase up to $300 million of the Company's Class A common stock. The repurchase program, which expires in September 2016, does not obligate the Company to acquire any specific number of shares and may be discontinued or extended at any time by the board of directors. Share repurchases under the program may be made from time-to-time through open market transactions, block trades, privately negotiated transactions or otherwise, including under plans complying with both Rule 10b-18 and Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. At March 31, 2016 and December 31, 2015, the Company has a remaining share repurchase authorization of $264.4 million. The Company currently intends to hold its repurchased shares as treasury stock.
CEO stock contributions
In 2015, the CEO contributed an aggregate 5.2 million 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 were 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 0.5 million shares of Class B common stock from January 2015 through April 2015.  In May 2015, the CEO contributed back to the Company 4.7 million 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 retired during 2015.

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 2014 Employee Stock Purchase Plan (ESPP). No new options or awards have been granted under the 2010 Plan since June 2014. Outstanding options and awards under the 2010 plan continue to be subject to the terms and conditions of the 2010 Plan. Options granted under the 2014 Plan generally expire within 10 years from the date of grant and generally vest over four years. RSUs granted under the 2014 Plan generally vest annually over a four year period based upon continued service and are settled at vesting in shares of the Company's Class A common stock. 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 lesser of the fair market value of the stock as of the first date or the ending date of each six month offering period. For additional information regarding the Company's equity incentive plans, please refer to the audited financial statements contained in its 2015 Annual Report.

In June 2014, the Company granted an award of 4.5 million RSUs to the Company's CEO (CEO RSUs), which included 1.5 million RSUs that vested immediately upon grant and 3.0 million RSUs that were subject to both a market-based condition and a service condition. The market-based condition was achieved in January 2015. Stock-based compensation expense related to the CEO RSUs was $2.4 million and $15.8 million for the three months ended March 31, 2016 and 2015, respectively.
Employee stock purchase plan
In the three months ended March 31, 2016 and 2015, the Company issued 431,673 and 313,233 shares under the ESPP at weighted average prices of $8.76 and $20.40, respectively. The weighted-average fair value of each right to purchase shares of common stock granted under the ESPP was $3.49 and $16.56 for the three months ended March 31, 2016 and 2015, respectively. At March 31, 2016, there were 5.6 million shares reserved for future issuances under the ESPP.
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. The fair value of RSUs is determined using the Company's stock price on the date of grant. 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 2015 Annual Report.

Net income per share attributable to common stockholders
Net income per share attributable to common stockholders
Net income (loss) per share
Basic net income per share is computed by dividing the net income by the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted-average number of common shares outstanding, including all potentially dilutive common shares.
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.
Undistributed earnings are allocated based on the contractual participation rights of Class A and Class B 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 per share of Class A common stock assumes the conversion of Class B common stock.

Income taxes
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, a cumulative adjustment is made in that quarter.

The Company recorded an income tax benefit of $14.3 million for the three months ended March 31, 2016 due to a pre-tax net loss, which resulted in an effective tax rate of 11.7%. The Company's lower effective tax rate for 2016 compared to 2015 resulted from incurring a higher proportion of its first quarter 2016 net loss in foreign jurisdictions that provide little or no tax benefit and a tax benefit from restructuring charges in the first quarter of 2016. The Company's provision for income taxes in each period has differed from the tax computed at U.S. federal statutory tax rates due to state taxes, the effect of non-U.S. operations, deductible and non-deductible stock-based compensation expense, and adjustments to unrecognized tax benefits.
The Company is currently under examination by the Internal Revenue Service for the 2012 through 2014 tax years and 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 examinations are resolved unfavorably, there is a possibility it may have a material negative impact on the Company's results of operations.
At March 31, 2016 and December 31, 2015, the Company’s gross unrecognized tax benefits was $45.4 million and $36.3 million, respectively. If recognized, $31.1 million of these unrecognized tax benefits (net of federal benefit) at March 31, 2016 would be recorded as a reduction of future income tax provision. 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.

Facility Leases
The Company leases its facilities under long-term operating leases, which expire at various dates through 2027. As of December 31, 2015, the Company’s total future minimum lease payments under noncancelable operating leases were $152.2 million. The Company has not entered into any new material lease commitments during the three months ended March 31, 2016. Rent expense was $5.4 million and $2.4 million for the three months ended March 31, 2016 and 2015, respectively.
Other Commitments
In the ordinary course of business, the Company also enters into multi-year agreements to purchase sponsorships with event organizers, resorts and athletes as part of its marketing efforts; software licenses related to its financial and IT systems; manufacturing equipment for tooling and molds; and various other contractual commitments. As of December 31, 2015, the Company’s undiscounted future expected obligations under these agreements were $28.8 million. During the three months ended March 31, 2016, the Company entered into new agreements, primarily related to software licenses that resulted in additional total commitments of approximately $5 million over the next several years.
Legal proceedings
From time to time, the Company is involved in legal proceedings in the ordinary course of business, including the litigation matters described in Part II, Item 1 of this quarterly report on Form 10-Q. Due to inherent uncertainties of litigation, the Company cannot accurately predict the ultimate outcome of these matters. The Company is unable at this time to determine whether the outcome of the litigation would have a material impact on the results of operations, financial condition or cash flows of the Company.
Indemnifications
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. It is not possible to determine the maximum potential amount under these indemnification agreements due to the Company’s limited history with indemnification claims and the unique facts and circumstances involved in each particular agreement. As of March 31, 2016, 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.

Concentrations of risk and segment information
Concentrations of risk and segment information
Concentrations of risk and geographic information
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.
Customers who represented 10% or more of the Company's net accounts receivable balance were as follows:

Supplier concentration
The Company relies on third parties for the supply and manufacture of its cameras and accessories, 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.

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 March 31, 2016 and December 31, 2015, long-lived assets, which represent gross property and equipment, located outside the United States, primarily in China, were $51.0 million and $47.6 million, respectively.

Basis of presentation (Policies)
Basis of presentation 
Basis of presentation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). The Company's fiscal year ends on December 31, and its fiscal quarters end on March 31, June 30, and September 30. The condensed consolidated financial statements reflect all adjustments (which are normal and recurring in nature) that management believes are necessary for the fair presentation of its financial statements, 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, 2015 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 on Form 10-Q should be read in conjunction with the Company's Annual Report on Form 10-K (Annual Report) for the year ended December 31, 2015. There have been no significant changes in the Company’s accounting policies from those disclosed in its Annual Report.
Principles of consolidation 
Principles of consolidation. These condensed 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. Significant estimates and assumptions made by management include those related to: revenue recognition (including sales returns, web-based sale deliveries at period-end, implied post contract support and marketing allowances), stock-based compensation, inventory valuation, product warranty liabilities, the valuation and useful lives of long-lived assets (property and equipment, goodwill and intangibles) 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 approximated net income. Therefore, the condensed consolidated statements of comprehensive income have been omitted

Effect on the financial statements or other significant matters
Standards that are not yet adopted
 
 
 
 
Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606)
 
This standard 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. In August 2015, the FASB deferred the effective date by one year while providing the option to adopt the standard on the original effective date of January 1, 2017. In March 2016, the FASB issued additional guidance regarding principal versus agent considerations in the accounting of revenue. The standard may be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption.
 
January 1, 2018
 
The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements and related disclosures.
ASU No. 2016-02, Leases (Topic 842)
 
This standard requires lessees to put most leases on their balance sheets but recognize the expenses on their income statements in a manner similar to current practice. Lessees would recognize a right-to-use asset and lease liability for all leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The new standard should be applied on a modified retrospective basis.
 
January 1, 2019
 
The Company is beginning to evaluate the impact that the adoption of this standard will have on its consolidated financial statements.
ASU No. 2016-09, Stock Compensation (Topic 718)
 
This standard requires income tax effects of awards to be recognized in the income statement when the awards vest or are settled, allowing an employer to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting, and to make a policy election to account for forfeitures as they occur. Early adoption is permitted for an entity in any interim or annual period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period.
 
January 1, 2017
 
The Company is beginning to evaluate the impact that the adoption of this standard will have on its consolidated financial statements.
Standards that were adopted
 
 
 
 
ASU No. 2015-03 and ASU 2015-15, Interest - Imputation of Interest (Subtopic 835-30)

 
ASU 2015-03 requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with debt discounts.
ASU 2015-15 was issued to provide clarification to ASU 2015-03 in that fees related to line-of-credit arrangements should continue to be presented as an asset and subsequently amortized ratably over the term of the line-of-credit arrangement.
 
January 1, 2016
 
The adoption of this standard did not have a material impact on the consolidated financial statements. At March 31, 2016, the Company presented debt issuance costs of $3.3 million related to its secured revolving credit facility as an asset on its consolidated balance sheet.
