Summary of business and significant accounting policies
Summary of significant accounting policies
Summary of business and significant accounting policies
GoPro, Inc. (GoPro or the Company) makes mountable and wearable cameras, drones 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 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.
Principles of consolidation. These consolidated financial statements include all the accounts of the Company and its wholly-owned 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 consolidated financial statements and accompanying notes. The Company bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. 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 (loss). For all periods presented, comprehensive income (loss) approximated net income (loss). Therefore, the consolidated statements of comprehensive income (loss) have been omitted.
Prior period reclassifications. Reclassifications of certain prior period amounts in the consolidated financial statements have been made to conform to the current period presentation.
Cash equivalents and marketable securities. Cash equivalents primarily consist of investments in money market funds with maturities of three months or less from the date of purchase. Marketable securities consist of commercial paper, U.S. agency securities, and corporate debt securities, and are classified as available-for-sale securities. The Company views these securities as available to support current operations and it has classified all available-for-sale securities as current assets. Available-for-sale securities are carried at fair value with unrealized gains and losses, if any, included in stockholders' equity. Unrealized losses are charged against other income (expense), net, for declines in fair value below the cost of an individual investment that is deemed to be other than temporary. The Company has not identified any marketable securities as other-than-temporarily impaired for the periods presented. The cost of securities sold is based upon a specific identification method.
Accounts receivable and allowance for doubtful accounts. Accounts receivable are stated at invoice value less estimated allowances for returns and doubtful accounts. Allowances are recorded based on the Company's assessment of various factors, such as: historical experience, credit quality of its customers, age of the accounts receivable balances, geographic related risks, economic conditions and other factors that may affect a customer’s ability to pay. The allowance for doubtful accounts as of December 31, 2016 and 2015 was $1.3 million and $1.4 million, respectively.
Inventory. Inventory consists of finished goods and component parts, which are purchased directly or from contract manufacturers. Inventory is stated at the lower of cost or market on a first-in, first-out basis. The Company writes down its inventory for estimated obsolescence or excess inventory equal to the difference between the cost of inventory and estimated market value. The Company’s assessment of market value is based upon assumptions around market conditions and estimated future demand for its products within a specified time horizon, generally 12 months. Adjustments to reduce inventory to net realizable value are recognized in cost of revenue.
Point of purchase (POP) displays. The Company provides retailers with POP displays, generally free of charge, in order to facilitate the marketing of the Company’s products within retail stores. The POP displays contain a display that broadcasts video images taken by GoPro cameras with product placement available for cameras and accessories. POP display costs, less any fees charged, are capitalized as long-term assets and charged to sales and marketing expense over the expected period of benefit, which generally ranges from 24 to 36 months. Cash outflows and amortization related to POP displays are classified as operating activities in the consolidated statement of cash flows. Amortization was $19.6 million, $16.8 million and $18.0 million in 2016, 2015 and 2014, respectively.
Property and equipment, net. Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful life of the assets, ranging from one to ten years. Leasehold improvements are amortized over the shorter of the lease term or their expected useful life. Property and equipment pending installation, configuration or qualification are classified as construction in progress. Costs of maintenance and repairs that do not improve or extend the lives of the respective assets are expensed as incurred.
Fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the reporting date. The Company estimates and categorizes the fair value of its financial assets by applying the following hierarchy:
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. 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.
Leases. The Company leases its office space and facilities under cancelable and non-cancelable operating leases. For leases that contain rent escalation or rent concession provisions, the Company recognizes rent expense on a straight-line basis over the term of the lease. The Company does not assume renewals in its determination of the lease term unless the renewals are deemed to be reasonably assured at lease inception.
Goodwill and other intangible assets. Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in a business combination. Acquired intangible assets other than goodwill are amortized over their useful lives unless the lives are determined to be indefinite. For intangible assets acquired in a business combination, the estimated fair values of the assets received are used to establish their recorded values. Valuation techniques consistent with the market approach, income approach and/or cost approach are used to measure fair value.
Impairment of goodwill and long-lived assets. The Company performs an annual assessment of its goodwill during the fourth quarter of each calendar year or more frequently if indicators of potential impairment exist, such as an adverse change in business climate or a decline in the overall industry demand, that would indicate it is more likely than not that the fair value of its single reporting unit is less than its carrying value. There was no impairment of goodwill for any periods presented. For the annual impairment testing in 2016, the Company performed a quantitative analysis and determined the fair value of its single reporting unit exceeded the carrying value. Other indefinite-lived intangible assets are assessed for impairment at least annually. If their value carrying value exceeds the estimated fair value, the difference is recorded as an impairment. See Note 4 for information regarding impairment charges recorded for indefinite-lived intangible assets.
Long-lived assets, such as property and equipment and intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of assets to be held and used is measured by comparing the carrying amount to the estimated future undiscounted cash flows expected to be generated by the asset group. If it is determined that an asset group is not recoverable, an impairment charge is recognized for the amount by which the carrying amount of the asset group exceeds its fair value. There was no material impairment of long-lived assets for any periods presented.
Warranty. The Company records a liability for estimated product warranty costs at the time product revenue is recognized. The Company's standard warranty obligation to its end-users generally provides a 12-month warranty coverage on all of its products except in the European Union where the Company provides a two-year warranty. The Company's estimate of costs to service its warranty obligations is based on its historical experience of repair and replacement of the associated products and expectations of future conditions. The warranty obligation is affected by product failure rates and the related use of materials, labor costs and freight incurred in correcting any product failure.
Revenue recognition. Revenue is primarily comprised of product revenue, net of returns and sales incentives. The Company derives substantially all of its revenue from the sale of cameras, mounts and accessories and the related implied post contract support (PCS). The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collectability is reasonably assured. For most of the Company's revenue, these criteria are met at the time the product is shipped. For customers who purchase products directly from the Company’s website, revenue is deferred until delivery to the customer's address because the Company retains a portion of the risk of loss on these sales during transit.
The Company grants limited rights to return product for certain large retailers and distributors. The Company records reductions to revenue and cost of sales for expected future product returns at the time of sale based on analyses of historical return trends by customer class. Return trends are influenced by product life cycles, new product introductions, market acceptance of products, product sell-through, the type of customer, seasonality, and other factors. Return rates may fluctuate over time, but are sufficiently predictable to allow the Company to estimate expected future product returns.
The Company's camera sales are multiple element arrangements that generally include the following two units of accounting: a) the hardware component (camera and/or accessories) and the embedded firmware essential to the functionality of the camera delivered at the time of sale, and b) the implied right for the customer to receive PCS. PCS includes the right to receive, on a when and if available basis, future unspecified firmware upgrades and features as well as bug fixes, email and telephone support. The Company accounts for each element separately and allocates revenue based on its best estimate of the selling price (BESP). The Company's process for determining BESP considers multiple factors that may vary over time depending upon the unique facts and circumstances related to each deliverable, including: the level of support provided to customers, estimated costs to provide the Company's support, the amount of time and cost that is allocated to the Company's efforts to develop the undelivered elements, and market trends in the pricing for similar offerings. The Company also offers several mobile and desktop applications at no charge to help users manage, edit, view and share their content. These applications are not essential to the functionality of the camera, therefore, are not accounted as a separate element of the arrangement.
Revenue allocated to the delivered hardware and the related essential software is recognized at the time of sale provided the conditions for recognition of revenue have been met. Revenue allocated to PCS is deferred and recognized on a straight-line basis over the estimated term of the support period, which is estimated to be 15 months based on historical experience. Deferred revenue also includes amounts related to the Company’s GoPro Care and GoPro Plus fee-based service offerings.
Sales incentives. The Company offers sales incentives through various programs, consisting primarily of cooperative advertising and marketing development fund programs. Sales incentives are recorded as a reduction to revenue in the period the incentives are offered to the Company’s customers or the related revenue is recognized, whichever is later. In addition, the Company offers price protection discounts to certain customers when camera device models are released or repriced and the customer has remaining inventory on hand. The Company calculates price protection discounts in the period that the price reduction goes into effect, and they are recorded as a reduction of revenue, based on the evaluation of inventory currently held by the customer subject to price protection.
Shipping costs. Amounts billed to customers for shipping and handling are classified as revenue and the Company's related shipping and handling costs incurred are classified as cost of revenue.
Sales taxes. Sales taxes collected from customers and remitted to respective governmental authorities are recorded as liabilities and not included in revenue.
Advertising costs. Advertising costs consist of costs associated with print, television and ecommerce media advertisements and are expensed as incurred. The Company incurs promotional expenses resulting from payments under event, resort and athlete sponsorship contracts. These sponsorship arrangements are considered to be executory contracts and, as such, the costs are expensed as performance under the contract is received. The costs associated with preparation of sponsorship activities, including the supply of GoPro products, media team support, and activation fees are expensed as incurred. Prepayments made under sponsorship agreements are included in prepaid expenses or other long-term assets depending on the period to which the prepayment applies. Advertising costs were $106.0 million, $64.7 million and $47.2 million in 2016, 2015 and 2014, respectively.
Stock-based compensation. The Company accounts for stock-based compensation in accordance with accounting guidance that requires all stock-based awards granted to employees and directors to be measured at fair value and recognized as an expense. The Company primarily issues restricted stock units. For service-based awards, stock-based compensation is recognized on a straight-line basis over the requisite service period, net of estimated forfeitures. For performance and market-based awards which also require a service period, the Company uses graded vesting over the longer of the derived service period or when the performance or market condition is satisfied.
The Company recognizes a benefit from stock-based compensation as additional paid-in capital if an excess tax benefit is realized by following the with-and-without approach. The indirect effects of stock-based compensation deductions are reflected in the income tax provision for purposes of measuring the excess tax benefit at settlement of awards.
Foreign currency. The U.S. dollar is the functional currency of the Company's foreign subsidiaries. The Company remeasures monetary assets or liabilities denominated in currencies other than the U.S. dollar using exchange rates prevailing on the balance sheet date, and non-monetary assets and liabilities at historical rates. Foreign currency remeasurement and transaction gains and losses are included in other expense, net and have not been material for any periods presented.
Income taxes. The Company utilizes the asset and liability method for computing its income tax provision, under which deferred tax assets and liabilities are recognized for the expected future consequences of temporary differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates. Management makes estimates, assumptions and judgments to determine the Company's provision for income taxes, deferred tax assets and liabilities, and any valuation losses recorded against deferred tax assets. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent the Company believes recovery is not likely, establishes a valuation allowance.
The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. Interest and penalties related to unrecognized tax benefits are recognized within income tax expense.
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.

Recent accounting pronouncements
Standard
 
Description
 
Expected date of adoption
 
Effect on the financial statements or other significant matters
Standards that are not yet adopted
 
 
 
 
Revenue from Contracts with Customers
Accounting Standards Update (ASU) No. 2014-09, 2016-08, 2016-10 and 2016-12 (Topic 606)
 
The updated revenue standard establishes principles for recognizing revenue and develops a common revenue standard for all industries. Under the new model, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new standard requires that entities disclose the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Early adoption is permitted, but not earlier than the first quarter of 2017. The retrospective or cumulative effect transition method is permitted.
 
January 1, 2018
 
The Company completed an initial analysis of the impact of the standard on its sales contract portfolio by reviewing its current accounting policies and practices to identify potential differences that would result from applying the requirements of the new standard to its sales contracts. The Company does not anticipate a material impact on its consolidated financial statements because the analysis of its contracts under the new standard supports the recognition of most of its revenue at the time product is shipped, consistent with its current revenue policy. Although the Company is continuing to review certain aspects of its policies and practices, it expects that, as a result of the adoption of the new guidance, the timing of recognizing certain sales incentives as a reduction of revenue will generally be earlier than under the existing guidance. The Company expects to utilize the modified retrospective transition method. 

Leases
ASU No. 2016-02(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
 
Although the Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements and related disclosures, the Company currently expects that most of its operating lease commitments will be subject to the new standard and recognized as operating lease liabilities and right-of-use assets upon adoption.
Stock Compensation 
ASU No. 2016-09 (Topic 718)
 
This standard simplifies certain aspects of the accounting for share-based payment transactions, including income taxes, classification of awards and classification on the statement of cash flows. The new guidance also allows an entity 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.
 
January 1, 2017
 
The adoption of the standard resulted in a net cumulative-effect adjustment of $16.2 million to decrease accumulated deficit as of January 1, 2017, mostly related to the recognition of previously unrecognized excess tax benefits using the modified retrospective method. The previously unrecognized excess tax effects were recorded as a reduction to tax liabilities or an increase to deferred tax assets, which was fully offset by a valuation allowance. Without the valuation allowance, the Company’s deferred tax assets would have increased by $162.8 million. The Company elected to apply the change in presentation to the statements of cash flows prospectively and elected to account for forfeitures as they occur.
Income Taxes
ASU No. 2016-16 (Topic 740)
 
This standard requires entities to recognize at the transaction date the income tax consequences of intra-entity asset transfers. Previous guidance requires the tax effects from intra-entity asset transfers to be deferred until that asset is sold to a third party or recovered through use. The updated standard is effective in annual and interim periods in fiscal years beginning after December 15, 2017, with early adoption permitted during the first interim period of a fiscal year, and requires a modified retrospective transition method.
 
January 1, 2018
 
The Company is evaluating the impact that the adoption of this standard will have on its consolidated financial statements and related disclosures.
Intangible - Goodwill and Other
ASU No. 2017-04 (Topic 350)
 
This standard simplifies the accounting for goodwill and removes Step 2 of the annual goodwill impairment test. Upon adoption, goodwill impairment will be determined based on the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017, and requires a prospective transition method.
 
January 1, 2020
 
The Company is evaluating the impact that the adoption of this standard will have on its consolidated financial statements and related disclosures.
Business Acquisitions
Business Acquisitions
Business Acquisitions
In 2016, the Company completed acquisitions of two privately-held mobile editing application companies for total cash consideration of approximately $104 million. The aggregate allocation of the purchase prices primarily included $17.4 million of identifiable intangible assets, $3.4 million of net deferred tax liabilities and approximately $89 million of residual goodwill. Net tangible assets acquired were not material. In addition to the amounts above, aggregate deferred cash and stock compensation of up to approximately $35 million is payable to certain continuing employees subject to meeting specified future employment conditions. This amount is being recognized as compensation expense over the requisite service periods of up to four years from the respective acquisition dates, including approximately $22 million recognized in 2016.
In 2015, the Company completed several acquisitions qualifying as business combinations for aggregate consideration of $70.2 million, the substantial majority of which was cash consideration. The aggregated allocation of the purchased prices primarily included $32.3 million of identifiable intangible assets, $4.7 million of net deferred tax liabilities and approximately $43.0 million of residual goodwill. Net liabilities assumed were not material.
Goodwill is primarily attributable to expected synergies in the technologies that can be leveraged by the Company in future product offerings related to device and software related offerings. Goodwill is not expected to be deductible for U.S. income tax purposes. The operating results of the acquired companies have been included in the Company's consolidated financial statements for 2016 and 2015 from the date of acquisition.
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.

Financing Arrangements
Financing Arrangements
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 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.
As of December 31, 2016, the Company may borrow up to approximately $150 million under the Credit Facility and was in compliance with all financial covenants contained in the Credit Agreement. No borrowings have been made from the Credit Facility to date.

Initial public offering. In July 2014, the Company completed its IPO in which the Company issued and sold 8.9 million shares of Class A common stock at a public offering price of $24.00 per share and the selling stockholders sold 11.6 million shares of Class A common stock, including 2.7 million shares upon the underwriters' option to purchase additional shares. The Company did not receive any proceeds from the sale of shares by the selling stockholders. The total net proceeds received by the Company from the IPO were $200.8 million after deducting underwriting discounts and commissions.
Follow-on offering. In November 2014, the Company completed a follow-on offering in which the Company issued and sold 1.3 million shares of Class A common stock at a public offering price of $75.00 per share and the selling stockholders sold 10.6 million shares of Class A common stock, including 1.6 million shares upon the underwriters' option to purchase additional shares. The Company did not receive any proceeds from the sale of shares by the selling stockholders. The total net proceeds received by the Company from the follow-on offering were $93.2 million after deducting underwriting discounts and commissions.
Redeemable convertible preferred stock. Prior to the Company's IPO, the Company had 30.5 million of Series A redeemable convertible preferred stock outstanding, which were convertible into shares of Class B common stock at a rate of 1-for-1. Concurrent with the close of the IPO, those outstanding shares were converted into Class B common stock.
Common stock. Following the Company's IPO, the Company had two classes of authorized common stock: Class A common stock with 500 million shares authorized and Class B common stock with 150 million shares authorized. As of December 31, 2016, 104.6 million shares of Class A stock were issued and outstanding and 36.7 million shares of Class B stock were issued and outstanding. The rights of the holders of Class A and Class B common stock are identical, except with respect to voting power and conversion rights. Each share of Class A common stock is entitled to one vote per share and each share of Class B common stock is entitled to ten votes per share. Each share of Class B common stock is convertible at any time at the option of the stockholder into one share of Class A common stock and has no expiration date. The Class B common stock is also convertible into Class A common stock on the same basis upon any transfer, whether or not for value, except for “permitted transfers” as defined in the Company’s restated certificate of incorporation. Each share of Class B common stock will convert automatically into one share of Class A common stock upon the date when the outstanding shares of Class B common stock represent less than 10% of the aggregate number of shares of common stock then outstanding. As of December 31, 2016, the Class B stock continued to represent greater than 10% of the overall outstanding shares.
The Company had the following shares of common stock reserved for issuance upon the exercise of equity instruments as of December 31, 2016:

Stock repurchase program. The stock repurchase program authorized by the Company’s board of directors in September 2015 to repurchase up to $300 million of the Company's Class A common stock expired on September 30, 2016 and has not been renewed. The repurchase program did not obligate the Company to acquire any specific number of shares. Under the program, the Company repurchased approximately 1.5 million shares of its common stock at an average price of $23.05 per share, for an aggregate purchase price of approximately $35.6 million. The Company holds the repurchased shares as treasury stock.
CEO stock contributions. In the first half of 2015, the CEO contributed an aggregate 5.2 million 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 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 the year.

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). In 2014, the Company terminated the authority to grant new awards under the 2010 Plan and 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.
The 2014 Plan serves as the successor to the 2010 Plan and 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 qualified 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 and are exercisable for shares of the Company's Class A stock. Options with performance or market-based conditions are generally subject to a required service period along with the performance or market condition. RSUs granted under the 2014 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 values of the stock as of the first date or the ending date of each six-month offering period. The 2014 Plan and the ESPP also provides for automatic annual increases in the number of shares reserved for future issuance. 
Employee retirement plan. The Company has a defined contribution retirement plan covering U.S. and other international full-time employees that provides for voluntary employee contributions from 1% to 86% of annual compensation, subject to a maximum limit allowed by Internal Revenue Service guidelines. The Company matches 100% of each employee’s contributions up to a maximum of 4% of the employee's eligible compensation. The Company's matching contributions to the plan were $7.2 million, $5.5 million and $2.7 million in 2016, 2015 and 2014, respectively.

In June 2014, the Company granted an award of 4.5 million RSUs covering shares of the Company's Class B common stock 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 vesting condition and a three-year service-based vesting condition. The market-based condition was achieved in January 2015. Stock-based compensation expense related to the CEO RSUs was $6.4 million, $29.4 million and $38.3 million for 2016, 2015 and 2014, respectively.
Employee stock purchase plan In 2016 and 2015, the Company issued 668,107 and 436,924 shares under its ESPP at weighted average prices of $9.15 and $26.88, respectively. The weighted-average fair value of each right to purchase shares of the Company's Class A common stock granted under the ESPP was $3.99, $15.76 and $7.16 in 2016, 2015 and 2014, respectively.
Fair value disclosures The fair value of stock options granted and purchases under the Company's ESPP is estimated using the Black-Scholes option pricing model. Expected term of stock options granted was estimated based on the simplified method. Expected stock price volatility was estimated by taking the average historic price volatility for industry peers based on daily price observations over a period equivalent to the expected term. Risk-free interest rate was based on the yields of U.S. Treasury securities with maturities similar to the expected term. Dividend yield was zero as the Company does not have any history of, nor plans to make, dividend payments.
The fair value of stock options granted was estimated as of the grant date using the following assumptions:

The income tax benefit related to stock-based compensation expense was zero, $28.0 million and $19.5 million for 2016, 2015 and 2014, respectively. There is no current year tax benefit due to a full valuation allowance on U.S. net deferred tax assets (see Note 9 below).
At December 31, 2016, total unearned stock-based compensation of $116.3 million related to stock options, RSUs and ESPP shares is expected to be recognized over a weighted average period of 2.6 years.
Net income (loss) per share
Net income (loss) per share
Basic 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 during the period. All participating securities are excluded from basic weighted average common shares outstanding. 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 Company's IPO and their conversion, the Company considered its redeemable convertible preferred stock to be participating securities due to their non-cumulative dividend rights.
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 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.

As of December 31, 2016, $3.3 million of earnings had been indefinitely reinvested outside the U.S., primarily in active non-U.S. business operations. We do not intend to repatriate these earnings to fund U.S. operations and, accordingly, we do not provide for U.S. federal income and foreign withholding tax on these earnings.

The lower effective tax rates of 2016 compared to 2015 resulted from a significant benefit on pre-tax book losses, offset by the establishment of a valuation allowance on all U.S. federal and state net deferred tax assets and by income taxes paid at lower rates in profitable foreign jurisdictions (primarily wholly owned subsidiaries in Europe). The provision for income taxes in each period has differed from the tax computed at U.S. federal statutory tax rates due to change in valuation allowance, the effect of non-U.S. operations, deductible and non-deductible stock-based compensation expense, states taxes, federal research and development tax credits, and other adjustments.
The higher effective tax rate for 2015 compared to 2014 was due to higher U.S. taxable income and lower international taxable income, which resulted from incurring a higher proportion of our 2015 operating expenses in foreign jurisdictions. Additionally, the effective tax rate for 2015 was lower than the federal statutory rate of 35% primarily due to benefits from research and development tax credits.
Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities were as follows:

Recognition of deferred tax assets is appropriate when realization of such assets is more likely than not. Based upon the weight of available evidence, the Company believes it is not more likely that not that the U.S. deferred tax assets will be realized. Accordingly, a full valuation allowance is established against U.S. deferred tax assets. The foreign deferred tax assets in each jurisdiction are minimal and are supported by taxable income or in the case of acquired companies, by the future reversal of deferred tax liabilities. It is more likely than not that the Company's foreign deferred tax assets will be realized and thus, no valuation allowance is required on foreign deferred tax assets. The Company will continue to assess the realizability of the deferred tax assets in each of the applicable jurisdictions going forward. The Company's valuation allowance increased by $101.9 million to $110.4 million as of December 31, 2016, primarily due to the establishment of a full valuation allowance on all U.S. federal and state deferred tax assets. As of December 31, 2015, the Company had established a valuation allowance of $8.6 million for state research tax credits.
As of December 31, 2016, the Company’s federal, California and other state net operating loss carryforwards for income tax purposes were $467.2 million, $201.5 million and $207.3 million, respectively and federal and California state tax credit carryforwards were $32.5 million and $27.9 million, respectively. If not utilized, federal loss, federal credit and California loss carryforwards will begin to expire from 2030 to 2036, while other state loss carryforwards will begin to expire from 2019 to 2036. California tax credits may be carried forward indefinitely.
Under the provisions of §382 of the Internal Revenue Code, a change of control may impose an annual limitation on the amount of the Company’s net operating loss and tax credit carryforwards that can be used to reduce future tax liabilities. Of the Company’s total $467.2 million federal and state net operating loss carryforwards, approximately $8 million was from one of our 2016 acquisitions. These acquired tax attributes are subject to an annual limitation of $1.7 million per year for federal purposes and will begin to expire in the year 2034, if not utilized.
Uncertain income tax positions. The Company had gross unrecognized tax benefits of $56.9 million, $36.3 million and $16.6 million, as of December 31, 2016, 2015 and 2014, respectively. For fiscal 2016, 2015 and 2014, total unrecognized income tax benefits in an amount of $24.1 million, $31.0 million and $16.6 million, respectively, if recognized, would reduce income tax expense after considering the impact of the change in valuation allowance in the U.S. A material portion of our gross unrecognized tax benefits, if recognized, would increase the Company’s net operating loss carryforward, which would be offset by a full valuation allowance based on present circumstances.
These unrecognized tax benefits relate primarily to unresolved matters with taxing authorities regarding the Company’s transfer pricing positions and tax positions based on the Company’s interpretation of certain U.S. trial and appellate court decisions, which remain subject to appeal and therefore could be overturned in future periods. The Company’s existing tax positions will continue to generate an increase in unrecognized tax benefits in subsequent 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. Although the completion, settlement and closure of any audits is uncertain, it is reasonably possible that the total amount of unrecognized tax benefits will materially increase within the next 12 months. However, given the number of years remaining that are subject to examination, the range of the reasonably possible change cannot be estimated reliably.
A reconciliation of the beginning and ending amount of the unrecognized income tax benefits are as follows:

The Company’s policy is to account for interest and penalties related to income tax liabilities within the provision for income taxes. The balances of accrued interest and penalties recorded in the balance sheets and provision for income taxes were not material for any period presented.
The Company files income tax returns in the U.S. and non-U.S. jurisdictions. The Company is subject to federal, state and foreign income tax examinations for calendar tax years ending 2012 through 2015. The tax authorities could choose to audit the tax years beyond the statute of limitation period due to tax attribute carryforwards from prior years, making adjustments only to carryforward attributes. The Company is currently under examination by the Internal Revenue Service for the 2012 through 2015 tax years. At this time, the Company is not able to estimate the potential impact that the examination may have on income tax expense. If the examination is resolved unfavorably, there is a possibility it may have a material negative impact on the Company's results of operations.

At December 31, 2016, $11.5 million of the warranty liability was recorded as an element of accrued liabilities and $0.5 million was recorded as an element of other long-term liabilities.
Legal proceedings. From time to time, the Company is involved in legal proceedings in the ordinary course of business. 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 December 31, 2016, the Company has not paid any claims nor has it 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 geographic 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's management believes that credit risk for 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 products, some of which are sole-source suppliers. The Company's management 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.

Summary of business and significant accounting policies (Policies)
Basis of presentation 
Basis of presentation. The accompanying 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.
Principles of consolidation 
Principles of consolidation. These consolidated financial statements include all the accounts of the Company and its wholly-owned 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 consolidated financial statements and accompanying notes. The Company bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. 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 (loss) 
Comprehensive income (loss). For all periods presented, comprehensive income (loss) approximated net income (loss). Therefore, the consolidated statements of comprehensive income (loss) have been omitted
Prior period reclassifications 
Prior period reclassifications. Reclassifications of certain prior period amounts in the consolidated financial statements have been made to conform to the current period presentation.
Cash equivalents and marketable securities 
Cash equivalents and marketable securities. Cash equivalents primarily consist of investments in money market funds with maturities of three months or less from the date of purchase. Marketable securities consist of commercial paper, U.S. agency securities, and corporate debt securities, and are classified as available-for-sale securities. The Company views these securities as available to support current operations and it has classified all available-for-sale securities as current assets. Available-for-sale securities are carried at fair value with unrealized gains and losses, if any, included in stockholders' equity. Unrealized losses are charged against other income (expense), net, for declines in fair value below the cost of an individual investment that is deemed to be other than temporary. The Company has not identified any marketable securities as other-than-temporarily impaired for the periods presented. The cost of securities sold is based upon a specific identification method.
Accounts receivable and allowance for doubtful accounts 
Accounts receivable and allowance for doubtful accounts. Accounts receivable are stated at invoice value less estimated allowances for returns and doubtful accounts. Allowances are recorded based on the Company's assessment of various factors, such as: historical experience, credit quality of its customers, age of the accounts receivable balances, geographic related risks, economic conditions and other factors that may affect a customer’s ability to pay.
Inventory 
Inventory. Inventory consists of finished goods and component parts, which are purchased directly or from contract manufacturers. Inventory is stated at the lower of cost or market on a first-in, first-out basis. The Company writes down its inventory for estimated obsolescence or excess inventory equal to the difference between the cost of inventory and estimated market value. The Company’s assessment of market value is based upon assumptions around market conditions and estimated future demand for its products within a specified time horizon, generally 12 months. Adjustments to reduce inventory to net realizable value are recognized in cost of revenue.
Point of purchase (POP) displays 
Point of purchase (POP) displays. The Company provides retailers with POP displays, generally free of charge, in order to facilitate the marketing of the Company’s products within retail stores. The POP displays contain a display that broadcasts video images taken by GoPro cameras with product placement available for cameras and accessories. POP display costs, less any fees charged, are capitalized as long-term assets and charged to sales and marketing expense over the expected period of benefit, which generally ranges from 24 to 36 months. Cash outflows and amortization related to POP displays are classified as operating activities in the consolidated statement of cash flows.
Property and equipment, net 
Property and equipment, net. Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful life of the assets, ranging from one to ten years. Leasehold improvements are amortized over the shorter of the lease term or their expected useful life. Property and equipment pending installation, configuration or qualification are classified as construction in progress. Costs of maintenance and repairs that do not improve or extend the lives of the respective assets are expensed as incurred.
Fair value measurements 
Fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the reporting date. The Company estimates and categorizes the fair value of its financial assets by applying the following hierarchy:
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. 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.
Leases 
Leases. The Company leases its office space and facilities under cancelable and non-cancelable operating leases. For leases that contain rent escalation or rent concession provisions, the Company recognizes rent expense on a straight-line basis over the term of the lease. The Company does not assume renewals in its determination of the lease term unless the renewals are deemed to be reasonably assured at lease inception.
Goodwill and other intangible assets 
Goodwill and other intangible assets. Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in a business combination. Acquired intangible assets other than goodwill are amortized over their useful lives unless the lives are determined to be indefinite. For intangible assets acquired in a business combination, the estimated fair values of the assets received are used to establish their recorded values. Valuation techniques consistent with the market approach, income approach and/or cost approach are used to measure fair value.
Impairment of goodwill 
Impairment of goodwill and long-lived assets. The Company performs an annual assessment of its goodwill during the fourth quarter of each calendar year or more frequently if indicators of potential impairment exist, such as an adverse change in business climate or a decline in the overall industry demand, that would indicate it is more likely than not that the fair value of its single reporting unit is less than its carrying value. There was no impairment of goodwill for any periods presented. For the annual impairment testing in 2016, the Company performed a quantitative analysis and determined the fair value of its single reporting unit exceeded the carrying value. Other indefinite-lived intangible assets are assessed for impairment at least annually. If their value carrying value exceeds the estimated fair value, the difference is recorded as an impairment. See Note 4 for information regarding impairment charges recorded for indefinite-lived intangible assets.
Long-lived assets, such as property and equipment and intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of assets to be held and used is measured by comparing the carrying amount to the estimated future undiscounted cash flows expected to be generated by the asset group. If it is determined that an asset group is not recoverable, an impairment charge is recognized for the amount by which the carrying amount of the asset group exceeds its fair value. There was no material impairment of long-lived assets for any periods presented.

See Note 4 for information regarding impairment charges recorded for indefinite-lived intangible assets.
Long-lived assets, such as property and equipment and intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of assets to be held and used is measured by comparing the carrying amount to the estimated future undiscounted cash flows expected to be generated by the asset group. If it is determined that an asset group is not recoverable, an impairment charge is recognized for the amount by which the carrying amount of the asset group exceeds its fair value. There was no material impairment of long-lived assets for any periods presented.
Warranty 
Warranty. The Company records a liability for estimated product warranty costs at the time product revenue is recognized. The Company's standard warranty obligation to its end-users generally provides a 12-month warranty coverage on all of its products except in the European Union where the Company provides a two-year warranty. The Company's estimate of costs to service its warranty obligations is based on its historical experience of repair and replacement of the associated products and expectations of future conditions. The warranty obligation is affected by product failure rates and the related use of materials, labor costs and freight incurred in correcting any product failure.
Revenue recognition 
Revenue recognition. Revenue is primarily comprised of product revenue, net of returns and sales incentives. The Company derives substantially all of its revenue from the sale of cameras, mounts and accessories and the related implied post contract support (PCS). The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collectability is reasonably assured. For most of the Company's revenue, these criteria are met at the time the product is shipped. For customers who purchase products directly from the Company’s website, revenue is deferred until delivery to the customer's address because the Company retains a portion of the risk of loss on these sales during transit.
The Company grants limited rights to return product for certain large retailers and distributors. The Company records reductions to revenue and cost of sales for expected future product returns at the time of sale based on analyses of historical return trends by customer class. Return trends are influenced by product life cycles, new product introductions, market acceptance of products, product sell-through, the type of customer, seasonality, and other factors. Return rates may fluctuate over time, but are sufficiently predictable to allow the Company to estimate expected future product returns.
The Company's camera sales are multiple element arrangements that generally include the following two units of accounting: a) the hardware component (camera and/or accessories) and the embedded firmware essential to the functionality of the camera delivered at the time of sale, and b) the implied right for the customer to receive PCS. PCS includes the right to receive, on a when and if available basis, future unspecified firmware upgrades and features as well as bug fixes, email and telephone support. The Company accounts for each element separately and allocates revenue based on its best estimate of the selling price (BESP). The Company's process for determining BESP considers multiple factors that may vary over time depending upon the unique facts and circumstances related to each deliverable, including: the level of support provided to customers, estimated costs to provide the Company's support, the amount of time and cost that is allocated to the Company's efforts to develop the undelivered elements, and market trends in the pricing for similar offerings. The Company also offers several mobile and desktop applications at no charge to help users manage, edit, view and share their content. These applications are not essential to the functionality of the camera, therefore, are not accounted as a separate element of the arrangement.
Revenue allocated to the delivered hardware and the related essential software is recognized at the time of sale provided the conditions for recognition of revenue have been met. Revenue allocated to PCS is deferred and recognized on a straight-line basis over the estimated term of the support period, which is estimated to be 15 months based on historical experience. Deferred revenue also includes amounts related to the Company’s GoPro Care and GoPro Plus fee-based service offerings.
Sales incentives 
Sales incentives. The Company offers sales incentives through various programs, consisting primarily of cooperative advertising and marketing development fund programs. Sales incentives are recorded as a reduction to revenue in the period the incentives are offered to the Company’s customers or the related revenue is recognized, whichever is later. In addition, the Company offers price protection discounts to certain customers when camera device models are released or repriced and the customer has remaining inventory on hand. The Company calculates price protection discounts in the period that the price reduction goes into effect, and they are recorded as a reduction of revenue, based on the evaluation of inventory currently held by the customer subject to price protection.
Shipping costs 
Shipping costs. Amounts billed to customers for shipping and handling are classified as revenue and the Company's related shipping and handling costs incurred are classified as cost of revenue.
Sales taxes 
Sales taxes. Sales taxes collected from customers and remitted to respective governmental authorities are recorded as liabilities and not included in revenue.
Advertising costs 
Advertising costs. Advertising costs consist of costs associated with print, television and ecommerce media advertisements and are expensed as incurred. The Company incurs promotional expenses resulting from payments under event, resort and athlete sponsorship contracts. These sponsorship arrangements are considered to be executory contracts and, as such, the costs are expensed as performance under the contract is received. The costs associated with preparation of sponsorship activities, including the supply of GoPro products, media team support, and activation fees are expensed as incurred. Prepayments made under sponsorship agreements are included in prepaid expenses or other long-term assets depending on the period to which the prepayment applies.
Stock-based compensation 
Stock-based compensation. The Company accounts for stock-based compensation in accordance with accounting guidance that requires all stock-based awards granted to employees and directors to be measured at fair value and recognized as an expense. The Company primarily issues restricted stock units. For service-based awards, stock-based compensation is recognized on a straight-line basis over the requisite service period, net of estimated forfeitures. For performance and market-based awards which also require a service period, the Company uses graded vesting over the longer of the derived service period or when the performance or market condition is satisfied.
The Company recognizes a benefit from stock-based compensation as additional paid-in capital if an excess tax benefit is realized by following the with-and-without approach. The indirect effects of stock-based compensation deductions are reflected in the income tax provision for purposes of measuring the excess tax benefit at settlement of awards.
Foreign currency 
Foreign currency. The U.S. dollar is the functional currency of the Company's foreign subsidiaries. The Company remeasures monetary assets or liabilities denominated in currencies other than the U.S. dollar using exchange rates prevailing on the balance sheet date, and non-monetary assets and liabilities at historical rates. Foreign currency remeasurement and transaction gains and losses are included in other expense, net and have not been material for any periods presented.
Income taxes 
Income taxes. The Company utilizes the asset and liability method for computing its income tax provision, under which deferred tax assets and liabilities are recognized for the expected future consequences of temporary differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates. Management makes estimates, assumptions and judgments to determine the Company's provision for income taxes, deferred tax assets and liabilities, and any valuation losses recorded against deferred tax assets. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent the Company believes recovery is not likely, establishes a valuation allowance.
The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. Interest and penalties related to unrecognized tax benefits are recognized within income tax expense.
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.

Effect on the financial statements or other significant matters
Standards that are not yet adopted
 
 
 
 
Revenue from Contracts with Customers
Accounting Standards Update (ASU) No. 2014-09, 2016-08, 2016-10 and 2016-12 (Topic 606)
 
The updated revenue standard establishes principles for recognizing revenue and develops a common revenue standard for all industries. Under the new model, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new standard requires that entities disclose the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Early adoption is permitted, but not earlier than the first quarter of 2017. The retrospective or cumulative effect transition method is permitted.
 
January 1, 2018
 
The Company completed an initial analysis of the impact of the standard on its sales contract portfolio by reviewing its current accounting policies and practices to identify potential differences that would result from applying the requirements of the new standard to its sales contracts. The Company does not anticipate a material impact on its consolidated financial statements because the analysis of its contracts under the new standard supports the recognition of most of its revenue at the time product is shipped, consistent with its current revenue policy. Although the Company is continuing to review certain aspects of its policies and practices, it expects that, as a result of the adoption of the new guidance, the timing of recognizing certain sales incentives as a reduction of revenue will generally be earlier than under the existing guidance. The Company expects to utilize the modified retrospective transition method. 

Leases
ASU No. 2016-02(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.

Although the Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements and related disclosures, the Company currently expects that most of its operating lease commitments will be subject to the new standard and recognized as operating lease liabilities and right-of-use assets upon adoption.
Stock Compensation 
ASU No. 2016-09 (Topic 718)
 
This standard simplifies certain aspects of the accounting for share-based payment transactions, including income taxes, classification of awards and classification on the statement of cash flows. The new guidance also allows an entity 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.
 
January 1, 2017
 
The adoption of the standard resulted in a net cumulative-effect adjustment of $16.2 million to decrease accumulated deficit as of January 1, 2017, mostly related to the recognition of previously unrecognized excess tax benefits using the modified retrospective method. The previously unrecognized excess tax effects were recorded as a reduction to tax liabilities or an increase to deferred tax assets, which was fully offset by a valuation allowance. Without the valuation allowance, the Company’s deferred tax assets would have increased by $162.8 million. The Company elected to apply the change in presentation to the statements of cash flows prospectively and elected to account for forfeitures as they occur.
Income Taxes
ASU No. 2016-16 (Topic 740)
 
This standard requires entities to recognize at the transaction date the income tax consequences of intra-entity asset transfers. Previous guidance requires the tax effects from intra-entity asset transfers to be deferred until that asset is sold to a third party or recovered through use. The updated standard is effective in annual and interim periods in fiscal years beginning after December 15, 2017, with early adoption permitted during the first interim period of a fiscal year, and requires a modified retrospective transition method.
 
January 1, 2018
 
The Company is evaluating the impact that the adoption of this standard will have on its consolidated financial statements and related disclosures.
Intangible - Goodwill and Other
ASU No. 2017-04 (Topic 350)
 
This standard simplifies the accounting for goodwill and removes Step 2 of the annual goodwill impairment test. Upon adoption, goodwill impairment will be determined based on the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017, and requires a prospective transition method.

Revenue from Contracts with Customers
Accounting Standards Update (ASU) No. 2014-09, 2016-08, 2016-10 and 2016-12 (Topic 606)
 
The updated revenue standard establishes principles for recognizing revenue and develops a common revenue standard for all industries. Under the new model, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new standard requires that entities disclose the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Early adoption is permitted, but not earlier than the first quarter of 2017. The retrospective or cumulative effect transition method is permitted.
 
January 1, 2018
 
The Company completed an initial analysis of the impact of the standard on its sales contract portfolio by reviewing its current accounting policies and practices to identify potential differences that would result from applying the requirements of the new standard to its sales contracts. The Company does not anticipate a material impact on its consolidated financial statements because the analysis of its contracts under the new standard supports the recognition of most of its revenue at the time product is shipped, consistent with its current revenue policy. Although the Company is continuing to review certain aspects of its policies and practices, it expects that, as a result of the adoption of the new guidance, the timing of recognizing certain sales incentives as a reduction of revenue will generally be earlier than under the existing guidance. The Company expects to utilize the modified retrospective transition method. 

Leases
ASU No. 2016-02(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.
