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 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 statement of the Company's 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, 2016 has been derived from the audited financial statements at that date, but does not include all 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, 2016. 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. 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, 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, intangible assets and goodwill) and income taxes. The Company bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from management's estimates. To the extent there are material differences between the estimates and the actual results, future results of operations could be affected.
Comprehensive income (loss). For all periods presented, comprehensive income (loss) approximated net income (loss). Therefore, the condensed 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.
Recent accounting standards
Standard
 
Description
 
Date of adoption
 
Effect on the financial statements or other significant matters
Standards that were adopted
 
 
 
 
Stock Compensation 
Accounting Standards Update (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.
 
January 1, 2017
 
Adoption of the standard resulted in the recognition of previously unrecognized excess tax benefits using the modified retrospective method. The Company recorded an increase to U.S. deferred tax assets of $179 million which was recorded directly against accumulated deficit. The increased deferred tax asset allowed for an offset against long-term income tax payable of $16 million. A full valuation allowance was provided on the remaining U.S. deferred tax asset of $163 million, which was also recorded against accumulated deficit. The net impact to equity was a decrease in the accumulated deficit of approximately $16 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.
Standards not yet adopted
 
 
 
 
Revenue from Contracts with Customers
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's 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. (For full year 2016, the Company recognized approximately $42 million as a reduction to revenue for such sales incentives.) 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. 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.
Income Taxes
ASU No. 2016-16 (Topic 740)
 
This standard requires entities to recognize the income tax consequences of intra-entity asset transfers when they occur. This removes the exception to postpone recognition until the asset has been sold to an outside party. 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


 
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.

Although there are several other new accounting standards issued or proposed by the FASB, which the Company has adopted or will adopt, as applicable, the Company does not believe any of these additional accounting pronouncements has had or will have a material impact on its financial statements.

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, 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.
At March 31, 2017 and December 31, 2016, the Company may borrow up to approximately $82 million and $150 million, respectively, 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.
Convertible Notes
On April 12, 2017, the Company issued $175 million aggregate principal amount of 3.50% Convertible Senior Notes due 2022 in a private offering to qualified institutional buyers. See Note 11 for further information.

Employee benefit plans
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 one to four years depended on the vesting conditions. Restricted stock units (RSUs) granted under the 2014 Plan generally vest over a two to 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 2016 Annual Report.

The market-based condition was achieved in January 2015. Stock-based compensation expense related to the CEO RSUs was $0.5 million and $2.4 million for the three months ended March 31, 2017 and 2016, respectively.
Employee stock purchase plan. In the three months ended March 31, 2017 and 2016, the Company issued 625,811 and 431,673 shares under its ESPP at weighted average prices of $8.02 and $8.76, respectively.
Stock-based compensation expense. The Company measures compensation expense for all stock-based payment awards based on the estimated fair values on the date of the grant. The fair value of stock options granted and ESPP issuances is estimated using the Black-Scholes option pricing model. The fair value of RSUs is determined using the Company's closing stock price on the date of grant. There have been no significant changes in the Company’s valuation assumptions from those disclosed in its 2016 Annual Report.
The following table summarizes stock-based compensation included in the condensed consolidated statements of operations:

The income tax benefit related to stock-based compensation expense was zero and $2.0 million for the three months ended March 31, 2017 and 2016, respectively. There was no income tax benefit in the three months ended March 31, 2017 due to a full valuation allowance on the Company's U.S. net deferred tax assets (see Note 6 below).
At March 31, 2017, total unearned stock-based compensation of $122.9 million related to stock options, RSUs and ESPP shares is expected to be recognized over a weighted average period of 2.3 years.
Net loss per share
Net loss per share
Net loss per share
Basic net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding, including all potentially dilutive common shares.
The rights of the holders of Class A common stock 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. The computation of the diluted net loss per share of Class A common stock assumes the conversion of Class B common stock.

Income taxes

Income taxes
The Company’s income tax expense and the resulting effective tax rate are based upon the estimated annual effective tax rates applicable for the respective period, including losses generated in countries where we are projecting annual losses for which a deferred tax asset is not anticipated to be recognized. In the fourth quarter of 2016, we recorded a full valuation allowance against our net U.S. deferred tax assets, and for the foreseeable future anticipate providing a valuation allowance against any additional deferred tax assets until such time it is more likely than not the benefit of these deferred tax assets may be recognized.
The Company's tax provision and the resulting effective tax rate for interim periods is determined based upon its estimated annual effective tax rate, adjusted for the effect of discrete items arising in that quarter. The Company also includes jurisdictions with a projected loss for the year (or year-to-date loss) where the Company cannot or does not expect to recognize a tax benefit from its estimated annual effective tax rate. The impact of such inclusions could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings or losses versus annual projections. 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 provision of $22.3 million for the three months ended March 31, 2017 on a pre-tax net loss of $88.9 million, which resulted in a negative effective tax rate of 25.1%. The Company’s income tax provision in the three months ended March 31, 2017 was principally composed of tax expenses incurred on pre-tax income in profitable foreign jurisdictions. While the Company incurred pre-tax losses in the United States and certain lower-rate jurisdictions, the Company does not expect to recognize any tax benefits on pre-tax losses in the United States due to a full valuation allowance recorded against its U.S. deferred tax assets. The effective tax rate of 11.7% for the three months ended March 31, 2016 resulted from the Company providing a net tax benefit on pre-tax losses in the United States, which was offset by income taxes at lower rates in profitable foreign jurisdictions (primarily related to the Company's wholly owned subsidiaries in Europe). Future changes in the forecast annual income (loss) projections, tax rate changes, or discrete tax items could result in significant adjustments to quarterly income tax expense (benefit) in future periods.
The Company is currently under examination by the Internal Revenue Service for the 2012 through 2015 tax years and 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 March 31, 2017 and December 31, 2016, the Company’s gross unrecognized tax benefits were $70.6 million and $56.9 million, respectively. If recognized, $16.6 million of these unrecognized tax benefits (net of U.S. federal benefit) at March 31, 2017 would be recorded as a reduction of future income tax provision. 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.

The Company incurs costs for Company-related chartered aircraft fees for the use of the CEO’s private plane. The Company recorded expense of zero and $0.3 million in the three months ended March 31, 2017 and 2016, respectively. As of March 31, 2017 and December 31, 2016, the Company had no accounts payable associated with these aircraft fees.
The Company obtained services from a vendor whose CEO is also one of the members of the Company's board of directors. The Company recorded expense of zero and $0.1 million in the three months ended March 31, 2017 and 2016, respectively. As of March 31, 2017 and December 31, 2016, the Company had accounts payable associated with this vendor of zero and $0.3 million, respectively.

Facility Leases. The Company leases its facilities under long-term operating leases, which expire at various dates through 2027. As of December 31, 2016, the Company’s total future minimum lease payments under noncancelable operating leases were $139.5 million. There have been no material changes to the Company's lease commitments during the first quarter of 2017. Rent expense was $5.2 million and $5.4 million for the three months ended March 31, 2017 and 2016, 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; and various other contractual commitments. As of December 31, 2016, the Company's total undiscounted future expected obligations under multi-year agreements described above with terms longer than one year was $53.7 million. During the three months ended March 31, 2017, the Company terminated a contract with a software license vendor that resulted in a reduction to the Company's future expected obligations of $4.5 million, including $3.0 million for the remainder of 2017 and $1.5 million for 2018. There were no other material changes during the first quarter of 2017.

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, 2017, 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.

First quarter 2017 restructuring
On March 15, 2017, the Company approved a restructuring to further reduce future operating expenses and better align resources around its long-term business strategy. The restructuring provided for a reduction of employee headcount and open positions, eliminating a total of approximately 270 positions, as well as the consolidation of certain leased office facilities. In the first quarter of 2017, the Company recorded restructuring charges of $9.1 million, including $8.5 million related to severance and $0.7 million related to accelerated depreciation. The actions associated with the restructuring are expected to be substantially completed in the third quarter of 2017.

On November 29, 2016, the Company approved a restructuring to reduce future operating expenses and achieve its goal of returning to profitability. The restructuring provided for a reduction of the Company's global workforce of approximately 15%, the closure of the Company’s entertainment group to concentrate on its core business and the consolidation of certain leased office facilities. Under the fourth quarter 2016 restructuring, the Company has recorded cumulative charges of $39.8 million, including $3.3 million in the three months ended March 31, 2017. The restructuring was largely completed by the end of the first quarter of 2017.

First quarter 2016 restructuring
On January 12, 2016, the Company approved a restructuring that provided for a reduction in the Company’s global workforce of approximately 7%. The Company incurred aggregate restructuring expenses of $6.5 million in the first quarter of 2016, which primarily included cash-based severance costs. The plan was completed as of March 31, 2016 and all costs have been paid. No charges were recorded in periods after March 31, 2016.
Subsequent Events (Notes)
Subsequent Events [Text Block]
Subsequent events
On April 12, 2017, the Company issued $175 million aggregate principal amount of 3.50% Convertible Senior Notes ("Notes") due 2022 in a private placement to initial purchasers for initial resale to qualified institutional buyers. The Notes mature on April 15, 2022, unless earlier repurchased or converted into shares of Class A common stock subject to certain conditions. The Notes are convertible into cash, shares of the Company’s Class A common stock, or a combination thereof, at the Company’s election, at an initial conversion rate of 94.0071 shares of common stock per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately $10.64 per share of common stock, subject to adjustment. The Company will pay interest on the Notes semi-annually in arrears on April 15 and October 15 of each year with interest payments beginning on October 15, 2017. Proceeds received from the issuance of the Notes will be allocated between a liability component (current and long-term debt) and an equity component (additional paid-in capital), within the consolidated balance sheet for the second quarter of 2017. The fair value of the liability component will be measured using rates determined for similar debt instruments without a conversion feature.
In connection with the offering, the Company entered into a prepaid forward stock repurchase transaction ("Prepaid Forward") with a financial institution ("Forward Counterparty"). Pursuant to the Prepaid Forward, the Company used approximately $78 million of the net proceeds from the offering of the Notes to pay the prepayment amount of the Prepaid Forward and the initial aggregate number of the Company’s Class A common stock underlying the Prepaid Forward is approximately 9.2 million shares (based on the closing sale price of the Company’s Class A common stock on NASDAQ on April 6, 2017). The expiration date for the Prepaid Forward is April 15, 2022, although it may be settled earlier in whole or in part. Upon settlement of the Prepaid Forward, at expiration or upon any early settlement, the Forward Counterparty will deliver to the Company the number of shares of Class A common stock underlying the Prepaid Forward or the portion thereof being settled early. The shares purchased under the Prepaid Forward will be treated as treasury stock on the consolidated balance sheet (and not outstanding for purposes of the calculation of basic and diluted earnings per share), but will remain outstanding for corporate law purposes, including for purposes of any future stockholders' votes, until the Forward Counterparty delivers the shares underlying the Prepaid Forward to the Company.
Summary of business and significant accounting policies (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 statement of the Company's 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, 2016 has been derived from the audited financial statements at that date, but does not include all 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, 2016. 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. 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, 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, intangible assets and goodwill) and income taxes. The Company bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from management's estimates. To the extent there are material differences between the estimates and the actual results, future results of operations could be affected.
Comprehensive income (loss) 
Comprehensive income (loss). For all periods presented, comprehensive income (loss) approximated net income (loss). Therefore, the condensed consolidated statements of comprehensive income (loss) have been omitted

Stock Compensation 
Accounting Standards Update (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.
 
January 1, 2017
 
Adoption of the standard resulted in the recognition of previously unrecognized excess tax benefits using the modified retrospective method. The Company recorded an increase to U.S. deferred tax assets of $179 million which was recorded directly against accumulated deficit. The increased deferred tax asset allowed for an offset against long-term income tax payable of $16 million. A full valuation allowance was provided on the remaining U.S. deferred tax asset of $163 million, which was also recorded against accumulated deficit. The net impact to equity was a decrease in the accumulated deficit of approximately $16 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.
Standards not yet adopted
 
 
 
 
Revenue from Contracts with Customers
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's 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. (For full year 2016, the Company recognized approximately $42 million as a reduction to revenue for such sales incentives.) 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. 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.
Income Taxes
ASU No. 2016-16 (Topic 740)
 
This standard requires entities to recognize the income tax consequences of intra-entity asset transfers when they occur. This removes the exception to postpone recognition until the asset has been sold to an outside party. 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


 
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.

Standards not yet adopted
 
 
 
 
Revenue from Contracts with Customers
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's 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. (For full year 2016, the Company recognized approximately $42 million as a reduction to revenue for such sales incentives.) 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. 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.
Income Taxes
ASU No. 2016-16 (Topic 740)
 
This standard requires entities to recognize the income tax consequences of intra-entity asset transfers when they occur. This removes the exception to postpone recognition until the asset has been sold to an outside party. 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


 
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.
