The Company and Summary of Significant Accounting Policies and Estimates	3 Months Ended

Accounting Policies [Abstract]
The Company and Summary of Significant Accounting Policies and Estimates	The Company and Summary of Significant Accounting Policies and Estimates The Company Logitech International S.A, together with its consolidated subsidiaries, ("Logitech" or the "Company") designs, manufactures and markets products that allow people to connect through music, gaming, video, computing, and other digital platforms. The Company sells its products to a broad network of domestic and international customers, including direct sales to retailers and indirect sales through distributors. Logitech was founded in Switzerland in 1981 and Logitech International S.A. has been the parent holding company of Logitech since 1988. Logitech International S.A. is a Swiss holding company with its registered office in Apples, Switzerland and headquarters in Lausanne, Switzerland, which conducts its business through subsidiaries in the Americas, Europe, Middle East and Africa ("EMEA") and Asia Pacific. Shares of Logitech International S.A. are listed on both the SIX Swiss Exchange under the trading symbol LOGN and the Nasdaq Global Select Market under the trading symbol LOGI. Basis of Presentation The condensed consolidated interim financial statements include the accounts of Logitech and its subsidiaries. All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and therefore do not include all the information required by GAAP for complete financial statements. They should be read in conjunction with the Company’s audited consolidated financial statements for the fiscal year ended March 31, 2017, included in its Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on May 26, 2017. In the opinion of management, these condensed consolidated financial statements include all adjustments, consisting of only normal and recurring adjustments, necessary and in all material aspects, for a fair statement of the results of operations, comprehensive income, financial position, cash flows and changes in shareholders' equity for the periods presented. Operating results for the three months ended June 30, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2018, or any future periods. Reclassification Certain amounts from the comparative period in the accompanying unaudited condensed consolidated financial statements have been reclassified to conform to the condensed consolidated financial statement presentation as of and for the three months ended June 30, 2017 . Changes in Significant Accounting Policies Other than the recent accounting pronouncements adopted, discussed below, there have been no substantial changes in the Company’s significant accounting policies during the three months ended June 30, 2017 compared with the significant accounting policies described in its Annual Report on Form 10-K for the fiscal year ended March 31, 2017 . Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Significant estimates and assumptions made by management involve the fair value of goodwill, intangible assets acquired from business acquisitions, warranty liabilities, accruals for customer programs and related breakage when appropriate, sales return reserves, allowance for doubtful accounts, inventory valuation, contingent consideration from business acquisitions and periodical reassessment of its fair value, share-based compensation expense, uncertain tax positions, and valuation allowances for deferred tax assets. Although these estimates are based on management’s best knowledge of current events and actions that may impact the Company in the future, actual results could differ materially from those estimates. Recent Accounting Pronouncements Adopted In July 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-11, "Simplifying the Measurement of Inventory (Topic 330)" ("ASU 2015-11"). Topic 330, Inventory, previously required an entity to measure inventory at the lower of cost or market, with market value represented by replacement cost, net realizable value or net realizable value less a normal profit margin. ASU 2015-11 requires an entity to measure inventory at the lower of cost or net realizable value and is effective for fiscal years beginning after December 15, 2016, with early adoption permitted. The Company has adopted this standard effective April 1, 2017 which did not have a material impact on its condensed consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" ("ASU 2016-09"). ASU 2016-09 simplifies several aspects of the accounting for share-based payments, including immediate recognition of all excess tax benefits and deficiencies in the income statement, changing the threshold to qualify for equity classification up to the employees' maximum statutory tax rates, allowing an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures as they occur, and clarifying the classification on the statement of cash flows for the excess tax benefits and employee taxes paid when an employer withholds shares for tax withholding purposes. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, with early adoption permitted. The Company has adopted this standard effective April 1, 2017. Changes to the statements of cash flows related to the classification of excess tax benefits were implemented on a retroactive basis and accordingly, to conform to the current year presentation, the Company reclassified $3.3 million of excess tax benefits previously reported under financing activities to operating activities for the three months ended June 30, 2016 on its condensed consolidated statements of cash flows. Under the new standard, the Company accounts for forfeitures as they occur. The change in accounting for forfeitures resulted in a cumulative-effect adjustment to decrease retained earnings as of March 31, 2017 by $3.3 million . The Company further recognized a cumulative-effect adjustment to increase retained earnings as of March 31, 2017 by $57.2 million upon adoption of the new guidance to account for gross excess tax benefits of $75.2 million that were previously not recognized because the related tax deduction had not reduced current income taxes, offset by a valuation allowance of $18.0 million to reduce the deferred tax assets to amounts that are more likely than not to be realized. In January 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment (Topic 350)" ("ASU 2017-04"), which removes Step 2 from the goodwill impairment test. ASU 2017-04 is effective for annual or any interim goodwill impairments in annual periods beginning December 15, 2019, with early adoption permitted. The Company has adopted this standard effective April 1, 2017 which did not have a material impact on its condensed consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting" ("ASU 2017-09"), which provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU 2017-09 is effective for annual periods beginning after December 15, 2017, with early adoption permitted, including adoption in any interim period for which financial statements have not yet been issued. The Company has adopted this standard effective April 1, 2017 which did not have a material impact on its condensed consolidated financial statements. Recent Accounting Pronouncements To Be Adopted In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09") which supersedes the revenue recognition requirements under ASC 605, Revenue Recognition. ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. 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 reporting companies to disclose the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new standard will become effective for the Company on April 1, 2018. The standard allows for either a "full retrospective" adoption, meaning the standard is applied to all of the periods presented subject to practical expedients, or a "modified retrospective" adoption, meaning the standard is applied only in the initial year, or interim period in year of initial application with a cumulative adjustment to opening retained earnings for existing contracts. The Company currently expects to utilize the modified retrospective transition method. The Company continues to evaluate the impact this new standard could have on the current contracts with customers and the accruals of various sales and marketing programs the Company offers and on the related breakage estimates. The Company has not completed its analysis of the impact to its condensed consolidated financial statements and this information will not be available until the Company completes its full assessment. It is possible that during the fiscal year 2018, the Company may identify certain areas which may result in material impact on the Company’s condensed consolidated financial statements, or the Company may revise its adoption method. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments-Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10)” ("ASU 2016-01"). ASU 2016-01 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, with early adoption permitted. The Company does not believe that the adoption of ASU 2016-01 will have a material impact on its condensed consolidated financial statements and will adopt this standard effective April 1, 2018. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" ("ASU 2016-02"), w hich requires the recognition of lease assets and lease liabilities arising from operating leases in the statement of financial position. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The Company is evaluating the full effect that ASU 2016-02 will have on its condensed consolidated financial statements and will adopt this standard effective April 1, 2019. In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory" ("ASU 2016-16"), which eliminates the deferral of income tax effects of intra-entity asset transfers until the transferred asset is sold to an unrelated party or recovered through use however, this standard does not apply to intra-entity transfer of inventory. ASU 2016-16 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, with early adoption permitted but only in the first interim period of an annual period. The cumulative effect of change on equity upon adoption is to be quantified under the modified retrospective approach and recorded as of the beginning of the period of adoption. The Company is evaluating the full effect that ASU 2016-16 will have on its condensed consolidated financial statements and will adopt this standard effective April 1, 2018. In December 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash" ("ASU 2016-18"), which requires that a statement of cash flows explains the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. ASU 2016-18 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, with early adoption permitted. The adoption of this standard should be applied using a retrospective transition method to each period presented. The Company does not expect the adoption of ASU 2016-18 will have a material impact on its condensed consolidated financial statements and will adopt this standard effective April 1, 2018. In March 2017, the FASB issued ASU 2017-07, "Compensation-Retirement Benefit (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" ("ASU 2017-07"), which requires that the Company disaggregate the service cost component from the other components of net benefit cost, and also provides guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allow only the service cost component of net benefit cost to be eligible for capitalization. ASU 2017-07 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, with early adoption permitted. The Company does not expect the adoption of ASU 2017-07 will have a material impact on its condensed consolidated financial statements and will adopt this standard effective April 1, 2018.

The following table summarizes the share-based compensation expense and total income tax benefit recognized for share-based awards for the three months ended June 30, 2017 and 2016 (in thousands): Three Months Ended 2017 2016 Cost of goods sold $ 711 $ 675 Marketing and selling 4,381 3,437 Research and development 1,543 914 General and administrative 4,070 3,491 Total share-based compensation expense 10,705 8,517 Income tax benefit (11,282 ) (1,815 ) Total share-based compensation expense (credit), net of income tax $ (577 ) $ 6,702 The income tax benefit in the respective period primarily consists of tax benefit related to the share-based compensation expense for the period and direct tax benefit realized, including net excess tax benefits recognized, from stock-based awards vested or exercised during the period. As of June 30, 2017 and 2016 , the Company capitalized $0.9 million and $0.5 million of stock-based compensation expense to inventory, respectively. Defined Benefit Plans Certain of the Company’s subsidiaries sponsor defined benefit pension plans or non-retirement post-employment benefits covering substantially all of their employees. Benefits are provided based on employees’ years of service and earnings, or in accordance with applicable employee benefit regulations. The Company’s practice is to fund amounts sufficient to meet the requirements set forth in the applicable employee benefit and tax regulations. The cost recorded of $2.3 million and $2.8 million for the three months ended June 30, 2017 and 2016 , respectively, was primarily related to service costs.

Income Taxes

Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company is incorporated in Switzerland but operates in various countries with differing tax laws and rates. Further, a portion of the Company’s income before taxes and the provision for (benefit from) income taxes are generated outside of Switzerland. The income tax benefit for the three months ended June 30, 2017 was $5.4 million based on an effective income tax rate of (17.2)% of pre-tax income, compared to an income tax provision of $3.1 million based on an effective income tax rate of 12.2% of pre-tax income for the three months ended June 30, 2016 . The change in the effective income tax rate for the three months ended June 30, 2017 , compared to the three months ended June 30, 2016 , is primarily due to the recognition of $9.9 million of excess tax benefits, offset by valuation allowance of $1.3 million for federal tax credit carryforwards after adoption of ASU 2016-09. In the three months ended June 30, 2017 and June 30, 2016 , there was a discrete tax benefit of $0.7 million for both periods from the reversal of uncertain tax positions from the expiration of statutes of limitations. As of June 30 and March 31 , 2017 , the total amount of unrecognized tax benefits due to uncertain tax positions was $65.0 million and $63.7 million , respectively, all of which would affect the effective income tax rate if recognized. The Company had $32.1 million in non-current income taxes payable and $1.5 million in current income taxes payable, including interest and penalties, related to its income tax liability for uncertain tax positions as of June 30, 2017 compared to $51.8 million in non-current income taxes payable and $1.5 million in current income taxes payable as of March 31, 2017 . The Company anticipates a settlement of approximately $1.4 million with the tax authorities in a foreign jurisdiction in the next twelve months. The Company recognizes interest and penalties related to unrecognized tax positions in income tax expense. As of June 30 and March 31, 2017 , the Company had $3.2 million and $3.0 million , respectively, of accrued interest and penalties related to uncertain tax positions. Although the Company has adequately provided for uncertain tax positions, the provisions on these positions may change as revised estimates are made or the underlying matters are settled or otherwise resolved. During fiscal year 2018, the Company will continue to review its tax positions and provide for or reverse unrecognized tax benefits as issues arise. During the next twelve months, it is reasonably possible that the amount of unrecognized tax benefits could increase or decrease significantly due to changes in tax law in various jurisdictions, new tax audits and changes in the U.S. dollar as compared to other currencies. Excluding these factors, uncertain tax positions may decrease by as much as $8.5 million from the lapse of the statutes of limitations in various jurisdictions during the next twelve months.

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Financial Instruments, Owned, at Fair Value [Abstract]
Fair Value Measurements	Fair Value Measurements Fair Value Measurements The Company considers fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The Company utilizes the following three-level fair value hierarchy to establish the priorities of the inputs used to measure fair value: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than quoted market prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. The following table presents the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis, excluding assets related to the Company’s defined benefit pension plans, classified by the level within the fair value hierarchy (in thousands): June 30, 2017 March 31, 2017 Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Assets: Cash equivalents $ 426,910 $ — $ — $ 448,742 $ — $ — Trading investments for deferred compensation plan included in other assets: Money market funds $ 3,107 $ — $ — $ 2,813 $ — $ — Mutual funds 13,807 — — 12,230 — — Total of trading investments for deferred compensation plan $ 16,914 $ — $ — $ 15,043 $ — $ — Currency exchange derivative assets $ — $ 104 $ — $ — $ 48 $ — Liabilities: Acquisition-related contingent $ — $ — $ 7,475 $ — $ — $ 9,908 Currency exchange derivative liabilities $ — $ 1,711 $ — $ — $ 443 $ — The following table summarizes the change in fair value of the Company’s contingent consideration balance during the three months ended June 30, 2017 and 2016 (in thousands): Three Months Ended 2017 2016 Beginning of the period $ 9,908 $ — Fair value of contingent consideration upon acquisition — 18,000 Change in fair value of contingent consideration (1,978 ) — Expected payment for first earn-out period(1) (455 ) — End of the period $ 7,475 $ 18,000 (1) As of June 30, 2017, the first twelve month earn-out period is complete and the earn-out payment of $0.5 million is based on the actual net sales of Jaybird products and no longer subject to fair value measurement. Investment Securities The marketable securities for the Company's deferred compensation plan are recorded at a fair value of $16.9 million and $15.0 million , respectively, as of June 30, 2017 and March 31, 2017 , based on quoted market prices. Quoted market prices are observable inputs that are classified as Level 1 within the fair value hierarchy. Unrealized trading gains / (losses) related to trading securities for the three months ended June 30, 2017 and 2016 were not material and are included in other expense, net in the Company's condensed consolidated statements of operations. Acquisition-related contingent consideration On April 20, 2016 (the "Acquisition Date"), the Company acquired all of the equity interest of JayBird, LLC (“Jaybird”). Pursuant to the purchase agreement, there is an additional earn-out of up to $45.0 million based on the achievement of certain net revenue growth targets over approximately a two-year period (the "Jaybird Acquisition"). The acquisition-related contingent consideration liability arising from the Jaybird Acquisition represents the future potential earn-out payments of up to $45.0 million based on the achievement of certain net revenue targets over approximately a two year period. If the net revenue targets are met, the Company will pay a maximum of $25.0 million and $20.0 million in fiscal years 2018 and 2019, respectively. The fair value of the earn-out as of the Acquisition Date was $18.0 million , which was determined by using a Monte Carlo Simulation that includes significant unobservable inputs such as a risk-adjusted discount rate of 16% and projected net sales of Jaybird over the earn-out period. The fair value is remeasured at each reporting period at the estimated fair value based on the inputs on the date of remeasurement, with the change in fair value recognized as "change in fair value of contingent consideration for business acquisition" in the operating expense section in the condensed consolidated statements of operations. Projected net sales are based on the Company's internal projections, including analysis of the target markets. The fair value of the contingent consideration was $7.9 million and $9.9 million as of June 30, 2017 and March 31, 2017, respectively. The decrease in fair value of contingent consideration for the three months ended June 30, 2017 results primarily from Jaybird's lower-than-expected net sales, partially offset by the change in the time value of money. As of June 30, 2017, the first twelve month earn-out period is complete and the expected earn-out payment of $0.5 million is included in the accrued and other current liabilities. Although these estimates are based on management’s best knowledge of current events, the estimates could change significantly from period to period. Any changes to the significant unobservable inputs used, including change in the forecast of net sales for the earn-out periods, may result in change in the fair value of contingent consideration, and could have a material impact on future results of operations. Actual payment of contingent consideration in the future could be different from the current estimated fair value of the contingent consideration. Assets Measured at Fair Value on a Nonrecurring Basis The Company’s non-marketable cost method investments, and non-financial assets, such as goodwill, intangible assets and property, plant and equipment, are recorded at fair value only upon initial recognition or if an impairment is recognized. There were no material impairments of long-lived assets during the three months ended June 30, 2017 or 2016 . Non-marketable cost method investments. These investments are classified as Level 3 due to the absence of quoted market prices, the inherent lack of liquidity, and the fact that inputs used to measure fair value are unobservable and require management's judgment. When certain events or circumstances indicate that impairment may exist, the Company revalues the investments using various assumptions, including the financial metrics and ratios of comparable public companies. The primary investment included in non-marketable investments is the Company’s investment in Series A Preferred Stock of Lifesize Inc. ("Lifesize") recorded at the fair value of $5.6 million on the date of the Lifesize divestiture. The aggregate recorded amount of cost method investments included in other assets as of June 30, 2017 and March 31, 2017 was $7.1 million and $7.4 million , respectively.

For products launched prior to April 1, 2014, the standard warranty period was up to five years. Starting from April 1, 2014, the standard warranty for all new products launched was changed to two years from the date of purchase for European Countries and generally one year from date of purchase for all other countries. Changes in the Company’s warranty liability for the three months ended June 30, 2017 and 2016 were as follows (in thousands): Three Months Ended 2017 2016 Beginning of the period $ 21,911 $ 20,380 Assumed from business acquisition — 1,813 Provision 5,124 3,177 Settlements (4,567 ) (3,428 ) Currency translation (412 ) (190 ) End of the period $ 22,056 $ 21,752 Guarantees Logitech Europe S.A., one of our wholly-owned subsidiaries, guaranteed payments of certain third-party contract manufacturers’ purchase obligations.

Indemnifications The Company indemnifies certain of its suppliers and customers for losses arising from matters such as intellectual property disputes and product safety defects, subject to certain restrictions. The scope of these indemnities varies, but in some instances, includes indemnification for damages and expenses, including reasonable attorneys’ fees. As of June 30, 2017 , no amounts have been accrued for these indemnification provisions. The Company does not believe, based on historical experience and information currently available, that it is probable that any material amounts will be required to be paid under its indemnification arrangements. The Company also indemnifies its current and former directors and certain of its current and former officers. Certain costs incurred for providing such indemnification may be recoverable under various insurance policies. The Company is unable to reasonably estimate the maximum amount that could be payable under these arrangements because these exposures are not limited, the obligations are conditional in nature and the facts and circumstances involved in any situation that might arise are variable. The stock purchase agreement entered on December 28, 2015 in connection with the investment by three venture capital firms in Lifesize contains representations, warranties and covenants of Logitech and Lifesize, Inc. to the Investors.

Based on currently available information, the Company does not believe that resolution of pending matters will have a material adverse effect on its financial condition, cash flows or results of operations. However, litigation is subject to inherent uncertainties, and there can be no assurances that the Company’s defenses will be successful or that any such lawsuit or claim would not have a material adverse impact on the Company’s business, financial condition, cash flows or results of operations in a particular period. Any claims or proceedings against the Company, whether meritorious or not, can have an adverse impact because of defense costs, diversion of management and operational resources, negative publicity and other factors. Any failure to obtain a necessary license or other rights, or litigation arising out of intellectual property claims, could adversely affect the Company’s business.

The Company and Summary of Significant Accounting Policies and Estimates (Policies)	3 Months Ended
	Jun. 30, 2017
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated interim financial statements include the accounts of Logitech and its subsidiaries. All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and therefore do not include all the information required by GAAP for complete financial statements. They should be read in conjunction with the Company’s audited consolidated financial statements for the fiscal year ended March 31, 2017, included in its Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on May 26, 2017. In the opinion of management, these condensed consolidated financial statements include all adjustments, consisting of only normal and recurring adjustments, necessary and in all material aspects, for a fair statement of the results of operations, comprehensive income, financial position, cash flows and changes in shareholders' equity for the periods presented. Operating results for the three months ended June 30, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2018, or any future periods.
Reclassification	Reclassification Certain amounts from the comparative period in the accompanying unaudited condensed consolidated financial statements have been reclassified to conform to the condensed consolidated financial statement presentation as of and for the three months ended June 30, 2017 .
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Significant estimates and assumptions made by management involve the fair value of goodwill, intangible assets acquired from business acquisitions, warranty liabilities, accruals for customer programs and related breakage when appropriate, sales return reserves, allowance for doubtful accounts, inventory valuation, contingent consideration from business acquisitions and periodical reassessment of its fair value, share-based compensation expense, uncertain tax positions, and valuation allowances for deferred tax assets. Although these estimates are based on management’s best knowledge of current events and actions that may impact the Company in the future, actual results could differ materially from those estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted In July 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-11, "Simplifying the Measurement of Inventory (Topic 330)" ("ASU 2015-11"). Topic 330, Inventory, previously required an entity to measure inventory at the lower of cost or market, with market value represented by replacement cost, net realizable value or net realizable value less a normal profit margin. ASU 2015-11 requires an entity to measure inventory at the lower of cost or net realizable value and is effective for fiscal years beginning after December 15, 2016, with early adoption permitted. The Company has adopted this standard effective April 1, 2017 which did not have a material impact on its condensed consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" ("ASU 2016-09"). ASU 2016-09 simplifies several aspects of the accounting for share-based payments, including immediate recognition of all excess tax benefits and deficiencies in the income statement, changing the threshold to qualify for equity classification up to the employees' maximum statutory tax rates, allowing an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures as they occur, and clarifying the classification on the statement of cash flows for the excess tax benefits and employee taxes paid when an employer withholds shares for tax withholding purposes. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, with early adoption permitted. The Company has adopted this standard effective April 1, 2017. Changes to the statements of cash flows related to the classification of excess tax benefits were implemented on a retroactive basis and accordingly, to conform to the current year presentation, the Company reclassified $3.3 million of excess tax benefits previously reported under financing activities to operating activities for the three months ended June 30, 2016 on its condensed consolidated statements of cash flows. Under the new standard, the Company accounts for forfeitures as they occur. The change in accounting for forfeitures resulted in a cumulative-effect adjustment to decrease retained earnings as of March 31, 2017 by $3.3 million . The Company further recognized a cumulative-effect adjustment to increase retained earnings as of March 31, 2017 by $57.2 million upon adoption of the new guidance to account for gross excess tax benefits of $75.2 million that were previously not recognized because the related tax deduction had not reduced current income taxes, offset by a valuation allowance of $18.0 million to reduce the deferred tax assets to amounts that are more likely than not to be realized. In January 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment (Topic 350)" ("ASU 2017-04"), which removes Step 2 from the goodwill impairment test. ASU 2017-04 is effective for annual or any interim goodwill impairments in annual periods beginning December 15, 2019, with early adoption permitted. The Company has adopted this standard effective April 1, 2017 which did not have a material impact on its condensed consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting" ("ASU 2017-09"), which provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU 2017-09 is effective for annual periods beginning after December 15, 2017, with early adoption permitted, including adoption in any interim period for which financial statements have not yet been issued. The Company has adopted this standard effective April 1, 2017 which did not have a material impact on its condensed consolidated financial statements. Recent Accounting Pronouncements To Be Adopted In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09") which supersedes the revenue recognition requirements under ASC 605, Revenue Recognition. ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. 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 reporting companies to disclose the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new standard will become effective for the Company on April 1, 2018. The standard allows for either a "full retrospective" adoption, meaning the standard is applied to all of the periods presented subject to practical expedients, or a "modified retrospective" adoption, meaning the standard is applied only in the initial year, or interim period in year of initial application with a cumulative adjustment to opening retained earnings for existing contracts. The Company currently expects to utilize the modified retrospective transition method. The Company continues to evaluate the impact this new standard could have on the current contracts with customers and the accruals of various sales and marketing programs the Company offers and on the related breakage estimates. The Company has not completed its analysis of the impact to its condensed consolidated financial statements and this information will not be available until the Company completes its full assessment. It is possible that during the fiscal year 2018, the Company may identify certain areas which may result in material impact on the Company’s condensed consolidated financial statements, or the Company may revise its adoption method. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments-Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10)” ("ASU 2016-01"). ASU 2016-01 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, with early adoption permitted. The Company does not believe that the adoption of ASU 2016-01 will have a material impact on its condensed consolidated financial statements and will adopt this standard effective April 1, 2018. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" ("ASU 2016-02"), w hich requires the recognition of lease assets and lease liabilities arising from operating leases in the statement of financial position. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The Company is evaluating the full effect that ASU 2016-02 will have on its condensed consolidated financial statements and will adopt this standard effective April 1, 2019. In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory" ("ASU 2016-16"), which eliminates the deferral of income tax effects of intra-entity asset transfers until the transferred asset is sold to an unrelated party or recovered through use however, this standard does not apply to intra-entity transfer of inventory. ASU 2016-16 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, with early adoption permitted but only in the first interim period of an annual period. The cumulative effect of change on equity upon adoption is to be quantified under the modified retrospective approach and recorded as of the beginning of the period of adoption. The Company is evaluating the full effect that ASU 2016-16 will have on its condensed consolidated financial statements and will adopt this standard effective April 1, 2018. In December 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash" ("ASU 2016-18"), which requires that a statement of cash flows explains the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. ASU 2016-18 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, with early adoption permitted. The adoption of this standard should be applied using a retrospective transition method to each period presented. The Company does not expect the adoption of ASU 2016-18 will have a material impact on its condensed consolidated financial statements and will adopt this standard effective April 1, 2018. In March 2017, the FASB issued ASU 2017-07, "Compensation-Retirement Benefit (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" ("ASU 2017-07"), which requires that the Company disaggregate the service cost component from the other components of net benefit cost, and also provides guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allow only the service cost component of net benefit cost to be eligible for capitalization. ASU 2017-07 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, with early adoption permitted. The Company does not expect the adoption of ASU 2017-07 will have a material impact on its condensed consolidated financial statements and will adopt this standard effective April 1, 2018.
