Accounting Policies [Abstract]
Basis of Presentation	1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC, and U.S. generally accepted accounting principles, or U.S. GAAP. However, certain information or footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to SEC rules and regulations. In our opinion, the financial statements include all adjustments, which are of a normal and recurring nature and necessary for the fair presentation of the results of the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the operating results for the full fiscal year or any future period. These financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended June 27, 2015. The consolidated financial statements include our financial statements and those of our wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated upon consolidation. Our fiscal year is the 52- or 53-week period ending on the last Saturday in June. Our fiscal 2016 and 2015 years are 52-week periods ending on June 25, 2016 and June 27, 2015, respectively. The quarterly fiscal periods presented in this report were 13-week periods and 26-week periods for the three and six months ended December 26, 2015 and December 27, 2014, respectively. For ease of presentation, the accompanying consolidated financial statements have been shown as ending on calendar quarter end dates as of and for all periods presented, unless otherwise indicated. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, allowance for doubtful accounts, cost of revenue, inventories, loss on purchase commitments, product warranty, accrued liabilities, share-based compensation costs, provision for income taxes, deferred income tax asset valuation allowances, uncertain tax positions, goodwill, intangible assets, investments, contingent consideration liability and loss contingencies. We base our estimates on historical experience, applicable laws and regulations, and various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Foreign Currency Transactions and Foreign Exchange Contracts The U.S. dollar is our functional and reporting currency. We remeasure our monetary assets and liabilities not denominated in the functional currency into U.S. dollar equivalents at the rate of exchange in effect on the balance sheet date. We measure and record non-monetary balance sheet accounts at the historical rate in effect at the date of transaction. We remeasure foreign currency expenses at the weighted average exchange rate in the month that the transaction occurred. These foreign currency transactions and remeasurement gains and losses, resulted in a net gain of $0.1 million and a net loss of $3.0 million in the three and six months ended December 31, 2015, and resulted in a net gain of $15.1 million and $14.9 million in the three and six months ended December 31, 2014. They are included in selling, general, and administrative expenses in the condensed consolidated statements of income. We enter into foreign currency contracts to manage exposure related to certain foreign currency obligations. The foreign currency contracts are not designated as hedging instruments and, accordingly, are not subject to hedge accounting. In fiscal year 2015, we entered into foreign currency forward contracts to purchase Japanese yen, using U.S. dollars. As of December 31, 2015, we had outstanding foreign currency forward contracts totaling ¥7.3 billion for a total of $60.5 million, at an average exchange rate of 120.51. The value date of the foreign currency forward contracts is March 11, 2016. The net fair value of the outstanding foreign currency forward contracts is disclosed in Note 4 Fair Value, and is recorded as a liability under other accrued liabilities in the condensed consolidated balance sheets. In the three and six months ended December 31, 2015, we recognized net unrealized losses of $0.4 million and net unrealized gains of $1.2 million, respectively, on the foreign currency forward contracts, which are recorded in selling, general, and administrative expenses in the condensed consolidated statements of income.

Revenue Recognition

Revenue Recognition [Abstract]
Revenue Recognition	2. Revenue Recognition We recognize revenue from product sales when there is persuasive evidence that an arrangement exists, delivery has occurred and title has transferred, the price is fixed or determinable, and collection is reasonably assured. We accrue for estimated sales returns, incentives, and other allowances at the time we recognize revenue. Our products contain embedded firmware and software, which together with, or consisting of, our ASIC chip, deliver the essential functionality of our products and, as such, software revenue recognition guidance is not applicable. Our sales to distributors are made under agreements that do not provide for price adjustments after purchase and provide for only limited return rights under product warranty. Revenue on these sales is recognized in the same manner as sales to our non-distributor customers.

Our diluted net income per share amounts for each period presented include the weighted average effect of potentially dilutive shares. We use the “treasury stock” method to determine the dilutive effect of our stock options, deferred stock units, or DSUs, and market stock units, or MSUs. Dilutive net income per share amounts do not include the potential weighted average effect of 969,730 and 532,982 shares of common stock related to certain share-based awards that were outstanding during the three months ended December 31, 2015 and 2014, respectively, and 717,991 and 332,892 shares of common stock related to certain share-based awards that were outstanding during the six months ended December 31, 2015 and 2014, respectively. These share-based awards were not included in the computation of diluted net income per share because their effect would have been antidilutive.

The contingent consideration liability recorded for business combinations was included in acquisition-related liabilities as of December 31, 2015 and June 30, 2015, respectively. We measure our foreign currency contracts at fair value on a recurring basis. We utilized Level 2 inputs to value the foreign currency forward contracts. Specifically, we utilized quoted prices for similar assets and liabilities in markets that are not active. Key inputs for the foreign currency forward contracts are spot rates and yield curves for the respective currencies. The foreign currency contracts were included in other accrued liabilities as of December 31, 2015 and June 30, 2015. Changes in fair value of our Level 3 financial assets as of December 31, 2015 were as follows (in millions): Balance as of June 30, 2015 $ 15.8 Net loss (1.0 ) Redemptions (0.6 ) Balance as of December 31, 2015 $ 14.2 Changes in fair value of our Level 3 contingent consideration liabilities as of December 31, 2015 were as follows (in millions): Balance as of June 30, 2015 $ 44.2 Cash settlement of contingent consideration liability (9.6 ) Accretion and remeasurement (1.6 ) Balance as of December 31, 2015 $ 33.0 In connection with our acquisition of Validity Sensors, Inc., or Validity, we entered into a contingent consideration arrangement. As of December 31, 2015, we may be required to make additional cash payments of up to $100.6 million as consideration to the former Validity stockholders and option holders based on unit sales of products utilizing Validity technology through March 2016. In connection with our acquisition of Pacinian Corporation, or Pacinian, we entered into a contingent consideration arrangement. As of December 31, 2015, we may be required to make additional cash payments of up to $10.0 million as consideration to the former Pacinian stockholders based on unit sales of products utilizing ThinTouch technology through June 2016. Changes in the fair value of our contingent consideration liabilities subsequent to the Validity and Pacinian acquisitions are included in operating expenses as change in contingent consideration in the condensed consolidated statements of income. Cash payments of contingent consideration are classified in the condensed consolidated statements of cash flows as a financing activity up to the amount of the contingent consideration recorded at the time of the acquisition, and as an operating activity for cash payments that exceed the liability recorded at the time of acquisition. There were no transfers in or out of our Level 1, 2, or 3 assets or liabilities during the three and six months ended December 31, 2015 and 2014. The fair values of our accounts receivable and accounts payable approximate their carrying values because of the short-term nature of those instruments. Intangible assets, property and equipment, and goodwill are measured at fair value on a non-recurring basis if impairment is indicated. The interest rate on our bank debt is variable, which is subject to change from time to time to reflect a market interest rate; accordingly, the carrying value of our bank debt approximates fair value.

Auction Rate Securities

Auction Rate Securities	6 Months Ended
	Dec. 31, 2015
Text Block [Abstract]
Auction Rate Securities	5. Auction Rate Securities Our ARS investments, which are primarily included in non-current other assets in the condensed consolidated balance sheets, have failed to settle in auctions beginning in 2007. These investments are not liquid, and in the event we need to access these funds, we will not be able to do so without a loss of principal, unless redeemed by the issuers or a future auction on these investments is successful. During the six months ended December 31, 2015, $0.6 million of our ARS investments were redeemed at par value. As there are currently no active markets for our various failed ARS investments, we have estimated the fair value of these investments as of December 31, 2015 using a trinomial discounted cash flow analysis. The analysis considered, among others, the following factors: · the collateral underlying the security investments; · the creditworthiness of the counterparty; · the timing of expected future cash flows; · the probability of a successful auction in a future period; · the underlying structure of each investment; · the present value of future principal and interest payments discounted at rates considered to reflect current market conditions; · a consideration of the probabilities of default, a successful future auction, or redemption at par for each period; and · estimates of the recovery rates in the event of default for each investment. When possible, our failed ARS investments were compared to other observable market data or securities with similar characteristics. Our estimate of the fair value of our ARS investments could fluctuate from period to period depending on future market conditions. We have ARS investments with a fair value of $12.4 million maturing in fiscal year 2018 and $1.8 million fair value with no maturity date. As of December 31, 2015, all of our ARS investments are below investment grade. The various types of ARS investments we held as of December 31, 2015, including the original cost basis, other-than-temporary impairment included in retained earnings, new cost basis, unrealized gain, and fair value, consisted of the following (in millions): Original Cost Basis Other-than- temporary Impairment in Retained Earnings New Cost Basis Unrealized Gain Fair Value Credit linked notes $ 13.5 $ (5.2 ) (1) $ 8.3 $ 4.1 $ 12.4 Preferred stock 5.0 (5.0 ) - 1.8 1.8 Total ARS $ 18.5 $ (10.2 ) $ 8.3 $ 5.9 $ 14.2 (1) Other-than-temporary impairment in retained earnings is partially offset by cumulative accretion of $3.1 million on non-current investments. Accretion is reclassified from accumulated other comprehensive income and recorded in the condensed consolidated statements of income as non-cash interest income. The various types of ARS investments we held as of June 30, 2015, including the original cost basis, other-than-temporary impairment included in retained earnings, new cost basis, unrealized gain, and fair value, consisted of the following (in millions): Original Cost Basis Other-than- temporary Impairment in Retained Earnings New Cost Basis Unrealized Gain Fair Value Credit linked notes $ 13.5 $ (6.1 ) (1) $ 7.4 $ 5.0 $ 12.4 Preferred stock 5.0 (5.0 ) - 2.8 2.8 Municipals 0.6 (0.1 ) 0.5 0.1 0.6 Total ARS $ 19.1 $ (11.2 ) $ 7.9 $ 7.9 $ 15.8 (1) Other-than-temporary impairment in retained earnings is partially offset by cumulative accretion of $2.7 million on non-current investments. Accretion is reclassified from accumulated other comprehensive income and recorded in the condensed consolidated statements of income as non-cash interest income. All of our ARS investments are accounted for as non-current as the maturity dates are more than 12 months from the balance sheet date. We do not intend to sell the ARS investments before the recovery of the amortized cost basis and it is not more likely than not that we will be required to sell the investments before the recovery of the amortized cost basis.

Commitments And Contingencies Disclosure [Abstract]
Product Warranties, Indemnifications, Contingencies and Legal Proceedings	9. Product Warranties, Indemnifications, Contingencies and Legal Proceedings Product Warranties We generally warrant our products for a period of 12 months from the date of delivery and accrue estimated probable product warranty costs as a cost of revenue at the time we recognize revenue. Factors that affect our warranty liability include historical and anticipated rates of warranty claims, materials usage, rework, and delivery costs. We assess the adequacy of our warranty obligations each reporting period and adjust the accrued warranty liability on the basis of our estimates. Indemnifications In connection with certain agreements, we are obligated to indemnify the counterparty against third party claims alleging infringement of certain intellectual property rights by us. We have also entered into indemnification agreements with our officers and directors. Maximum potential future payments cannot be estimated because these agreements do not have a maximum stated liability. However, historical costs related to these indemnification provisions have not been significant. We have not recorded any liability in our condensed consolidated financial statements for such indemnification obligations. Contingencies We have in the past and may in the future receive notices from third parties that claim our products infringe their intellectual property rights. We cannot be certain that our technologies and products do not and will not infringe issued patents or other proprietary rights of third parties. Any infringement claims, with or without merit, could result in significant litigation costs and diversion of management and financial resources, including the payment of damages, which could have a material adverse effect on our business, financial condition, and results of operations. Legal Proceedings In April 2015, we filed patent infringement actions with the United States District Court in the Northern District of California and with the United States International Trade Commission in which we allege certain competitor products infringe several of our patents. We intend to vigorously pursue these claims. In October 2015, Amkor Technology filed a complaint against us alleging infringement of intellectual property rights and various other claims. In November 2015, we filed an indemnification claim against the former stockholders and option holders of Validity to secure our rights under the Agreement and Plan of Reorganization between us and Validity. Pursuant to the Agreement, we can offset costs, damages and settlements against the contingent consideration earnout balance for certain of the claims brought by Amkor. Accordingly, we intend to reserve the majority of the remaining contingent consideration earnout balance and have reclassified the reserved balance from a current liability to a non-current liability, as final settlement of the Amkor complaint is not expected to occur within the next twelve months. We are involved in several other non-material litigation activities. We have expensed all legal fees incurred to date in connection with our legal activities.

Debt

Debt Disclosure [Abstract]
Debt	10. Debt We have a credit agreement, or the Credit Agreement, in place with the lenders party thereto, or the Lenders, and Wells Fargo Bank, National Association, or the Administrative Agent, as administrative agent for the Lenders. The Credit Agreement provides for, among other things, (i) a revolving credit facility of up to $250 million, which includes a $20 million sublimit for letters of credit and a $20 million sublimit for swingline loans, and (ii) a term loan facility in an amount of $150 million. Under the terms of the Credit Agreement, we may, subject to the satisfaction of certain conditions, request increases in the revolving credit facility commitments and additional term loan commitments in an aggregate principal amount of up to $100 million to the extent existing or new lenders agree to provide such increased or additional commitments, as applicable. We borrowed $150 million under the term loan facility and $100 million under the revolving credit facility. Initial debt issuance costs were approximately $5.0 million, which are being amortized over 60 months. Our obligations under the Credit Agreement are guaranteed by the material domestic subsidiaries of our company, subject to certain exceptions (such material subsidiaries, together with our company, collectively, the Credit Parties). The obligations of the Credit Parties under the Credit Agreement and the other loan documents delivered in connection therewith are secured by a first priority security interest in substantially all of the existing and future personal property of the Credit Parties, including, without limitation, 65% of the voting capital stock of certain of the Credit Parties’ direct foreign subsidiaries, subject to certain exceptions. The revolving credit facility and term loans bear interest at our election of a Base Rate plus an applicable margin or LIBOR plus an applicable margin. Swingline loans bear interest at a Base Rate plus an applicable margin. The Base Rate is a floating rate that is the greater of the Prime Rate, the Federal Funds Rate plus 50 basis points, or LIBOR plus 100 basis points. The applicable margin is based on a sliding scale which ranges from zero to 100 basis points for Base Rate loans and 100 basis points to 200 basis points for LIBOR loans. The term loan facility requires repayment over five years with nineteen quarterly principal payments which began in the three months ending March 31, 2015. Each of the first four quarterly principal payments is $1.9 million, each of the following quarterly principal payments is $3.8 million, with the final principal payment of $90.0 million due on September 30, 2019. The revolving credit facility requires payment in full at the end of five years on September 30, 2019. We are also required to pay a commitment fee for any unused portion of the revolving credit facility, which ranges from 0.25% to 0.45% per annum. Interest on the term loan facility and revolving credit facility is payable quarterly. As of December 31, 2015, the outstanding balance of the debt owed under the Credit Agreement was $242.5 million. On October 20, 2015, we entered into a Commitment Increase Agreement and First Amendment to Credit Agreement, or the First Amendment, with the Administrative Agent and each of the Lenders, which amends the Credit Agreement. Pursuant to the First Amendment, we exercised our right under the Credit Agreement to request a $100 million increase to the aggregate revolving credit commitment thereunder, for total aggregate revolving credit commitments of $250 million and the Lenders under the Credit Agreement agreed to provide such increased revolving credit. The First Amendment also amends the Credit Agreement by (i) reducing commitment fee rates set forth in the definition of Applicable Margin; (ii) providing that we may, from time to time, request incremental increases from the Lenders in the aggregate revolving and term commitments by an amount not exceeding $100 million, such increases to be in addition to the increase provided by the First Amendment; and (iii) making certain other administrative changes, all as set forth in the First Amendment. Borrowings under the Credit Agreement will continue to bear interest at a variable interest rate based on LIBOR or a Base Rate, in each case plus the Applicable Margin. The Applicable Margin is based on our consolidated total leverage ratio pursuant to a pricing grid set forth in the Credit Agreement. Under the Credit Agreement, there are restrictive operating covenants, including three financial covenants which limit the consolidated total leverage ratio, or leverage ratio, the consolidated interest coverage ratio, or interest coverage ratio, and places a restriction on the amount of capital expenditures that may be made in any fiscal year. The leverage ratio is the ratio of debt as of the measurement date to earnings before interest, taxes, depreciation and amortization, or EBITDA, for the four consecutive quarters ending with the quarter of measurement. The leverage ratio must not exceed 2.50 to 1.0 during the first two years of the agreement, and 2.0 to 1.0 during the last three years of the agreement. The interest coverage ratio is EBITDA to interest expense for the four consecutive quarters ending with the quarter of measurement. The interest coverage ratio must not be less than 3.50 to 1.0 during the term of the Credit Agreement. As of December 31, 2015, we were in compliance with the restrictive operating covenants.

Any additional shares repurchased under our common stock repurchase program would be available for issuance under our share-based compensation plans. Stock Options Stock option activity, including stock options granted, exercised, and forfeited, weighted average exercise prices for stock options outstanding and exercisable, and the aggregate intrinsic value were as follows: Stock Weighted Aggregate Option Average Intrinsic Awards Exercise Value Outstanding Price (in millions) Balance as of June 30, 2015 2,870,425 $ 38.50 Granted 239,840 84.34 Exercised (402,408 ) 29.40 Forfeited (4,265 ) 74.00 Balance as of December 31, 2015 2,703,592 43.86 $ 102.5 Exercisable at December 31, 2015 1,912,867 31.69 $ 94.4 The aggregate intrinsic value was determined using the closing price of our common stock on December 24, 2015 of $81.00 and excludes the impact of stock options that were not in-the-money. Deferred Stock Units DSU activity, including DSUs granted, delivered, and forfeited, and the balance and aggregate intrinsic value of DSUs was as follows: Aggregate Intrinsic DSU Awards Value Outstanding (in millions) Balance as of June 30, 2015 860,376 Granted 579,618 Delivered (269,344 ) Forfeited (26,070 ) Balance as of December 31, 2015 1,144,580 $ 92.7 The aggregate intrinsic value was determined using the closing price of our common stock on December 24, 2015 of $81.00. Of the shares delivered, 76,767 shares valued at $6.4 million were withheld to meet statutory minimum tax withholding requirements. Market Stock Units Our Amended and Restated 2010 Incentive Compensation Plan provides for the grant of MSU awards to our employees, consultants, and directors. An MSU is a promise to deliver shares of our common stock at a future date based on the achievement of market-based performance requirements in accordance with the terms of the MSU grant agreement. We have granted MSUs to our executive officers, which are designed to vest in three tranches with the target quantity for each tranche equal to one-third of the total MSU grant. The first tranche vests based on a one-year performance period; the second tranche vests based on a two-year performance period; and the third tranche vests based on a three-year performance period. Performance is measured based on the achievement of a specified level of total stockholder return, or TSR, relative to the TSR of the Philadelphia Semiconductor Index, or SOX Index. The potential payout ranges from 0% to 200% of the grant target quantity and is adjusted on a two-to-one ratio based on our TSR performance relative to the SOX Index TSR performance using the following formula: (100% + ([Synaptics TSR—SOX Index TSR] x 2)) Beginning with the MSU grants in fiscal 2015, the payout for tranche one and two will not exceed 100% and the payout for tranche three will be calculated based on the total target quantity for the entire grant multiplied by the payout factor, which will then be reduced by tranche one and tranche two stock issuances. Delivery of shares earned, if any, will take place on the dates provided in the applicable MSU grant agreement, assuming the grantee is still an employee, consultant, or director of our company at the end of the applicable performance period. On the delivery date, we withhold shares to cover statutory minimum tax withholding requirements and deliver a net quantity of shares to the employee, consultant, or director after such withholding. Until delivery of shares, the grantee has no rights as a stockholder with respect to any shares underlying the MSU award. During the six months ended December 31, 2015, MSU activity, including MSUs granted, delivered, and forfeited, and the balance and aggregate intrinsic value of MSUs as of December 31, 2015 was as follows: Aggregate Intrinsic MSU Awards Value Outstanding (in millions) Balance as of June 30, 2015 132,376 Granted 77,700 Performance adjustment 41,921 Delivered (103,199 ) Forfeited (2,648 ) Balance as of December 31, 2015 146,150 $ 11.8 We value the MSUs using the Monte Carlo simulation model on the date of grant and amortize the compensation expense over the three-year performance and service period on a straight-line basis. The unrecognized share-based compensation cost of our outstanding MSUs was approximately $13.2 million as of December 31, 2015, which will be recognized over a weighted average period of approximately 1.44 years.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	12. Income Taxes We account for income taxes under the asset and liability method. We consider the operating earnings of our foreign subsidiaries to be indefinitely invested outside the United States. Therefore, no provision has been made for the federal, state, or foreign taxes that may result from future remittances of undistributed earnings of our foreign subsidiaries. The provision for income taxes recorded in interim periods is recorded by applying the estimated annual effective tax rate to year-to-date income before provision for income taxes, excluding the effects of significant unusual or infrequently occurring discrete items. The tax effects of discrete items are recorded in the same period that the related discrete items are reported and results in a difference between the actual effective tax rate and the estimated annual effective tax rate. The provision for income taxes of $9.5 million and $8.3 million for the three months ended December 31, 2015 and 2014, respectively, represented estimated federal, state, and foreign income taxes. The effective tax rate for the three months ended December 31, 2015 and 2014, diverged from the combined U.S. federal and state statutory tax rate primarily because of foreign income taxed at lower tax rates and research credits, which included the retroactive reinstatement of the federal research credit, partially offset by foreign withholding taxes, nondeductible amortization, and net unrecognized tax benefits associated with qualified stock options. Federal research and development credits of $3.1 million generated from fiscal 2015 were treated as a discrete tax benefit in the three months ended December 31, 2015. The provision for income taxes for the three months ended December 31, 2014, excluding the impact of accounting for contingent consideration as a discrete item, would have been $9.2 million. The provision for income taxes of $18.7 million and $18.6 million for the six months ended December 31, 2015 and 2014, respectively, represented estimated federal, state, and foreign income taxes. The effective tax rate for the six months ended December 31, 2015 diverged from the combined U.S. federal and state statutory tax rate primarily because of foreign income taxed at lower tax rates and research credits, partially offset by foreign withholding taxes, nondeductible amortization and net unrecognized tax benefits associated with qualified stock options. Federal research and development credits of $3.1 million generated from fiscal 2015 were treated as a discrete tax benefit in the six months ended December 31, 2015. The effective tax rate for the six months ended December 31, 2014 diverged from the combined U.S. federal and state statutory tax rate primarily because of foreign income taxed at lower tax rates, partially offset by foreign withholding taxes, nondeductible amortization, and net unrecognized tax benefits associated with qualified stock options. The provision for income taxes for the six months ended December 31, 2014, excluding the impact of accounting for contingent consideration as a discrete item, would have been $20.5 million. On March 31, 2015, Japan’s parliament approved legislation to reduce corporate income tax rates by 3.29 percentage points over the next two years. As a result, the current combined national and local effective tax rate of 35.6% will be reduced to 32.3% over the next two years. We accounted for the impact of the tax rate change in the fourth quarter of our fiscal 2015. The Protecting Americans from Tax Hikes Act of 2015, or the PATH Act which made research tax credit permanent, was passed on December 17, 2015. The PATH Act retroactively extended federal research credit from January 1, 2015. As such, we recognized six months of tax benefit totaling $3.1 million from the federal research tax credit related to fiscal 2015 and another six months of federal research tax credit in the second quarter of fiscal 2016. The total liability for gross unrecognized tax benefits related to uncertain tax positions increased $2.3 million during the six months ended December 31, 2015 to $13.9 million from $11.6 million at June 30, 2015, and was included in other long-term liabilities on our condensed consolidated balance sheets. If recognized, the total gross unrecognized tax benefits would reduce the effective tax rate on income from continuing operations. Accrued interest and penalties related to unrecognized tax benefits as of December 31, 2015 was $1.4 million; this balance increased by $0.3 million from June 30, 2015. We classify interest and penalties as components of income tax expense. It is reasonably possible that the amount of the liability for unrecognized tax benefits may change within the next twelve months and an estimate of the range of possible changes is an increase in our liability up to $1.0 million. In July 2015, the U.S. Tax Court issued an opinion in Altera Corp. v. Commissioner In September 2015, we were notified by the National Tax Agency of Japan that our open tax years would be subject to audit. Our major tax jurisdictions are the United States, Hong Kong SAR, and Japan. From fiscal 2009 onward, we remain subject to examination by one or more of these jurisdictions.

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, allowance for doubtful accounts, cost of revenue, inventories, loss on purchase commitments, product warranty, accrued liabilities, share-based compensation costs, provision for income taxes, deferred income tax asset valuation allowances, uncertain tax positions, goodwill, intangible assets, investments, contingent consideration liability and loss contingencies. We base our estimates on historical experience, applicable laws and regulations, and various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
Foreign Currency Transactions and Foreign Exchange Contracts	Foreign Currency Transactions and Foreign Exchange Contracts The U.S. dollar is our functional and reporting currency. We remeasure our monetary assets and liabilities not denominated in the functional currency into U.S. dollar equivalents at the rate of exchange in effect on the balance sheet date. We measure and record non-monetary balance sheet accounts at the historical rate in effect at the date of transaction. We remeasure foreign currency expenses at the weighted average exchange rate in the month that the transaction occurred. These foreign currency transactions and remeasurement gains and losses, resulted in a net gain of $0.1 million and a net loss of $3.0 million in the three and six months ended December 31, 2015, and resulted in a net gain of $15.1 million and $14.9 million in the three and six months ended December 31, 2014. They are included in selling, general, and administrative expenses in the condensed consolidated statements of income. We enter into foreign currency contracts to manage exposure related to certain foreign currency obligations. The foreign currency contracts are not designated as hedging instruments and, accordingly, are not subject to hedge accounting. In fiscal year 2015, we entered into foreign currency forward contracts to purchase Japanese yen, using U.S. dollars. As of December 31, 2015, we had outstanding foreign currency forward contracts totaling ¥7.3 billion for a total of $60.5 million, at an average exchange rate of 120.51. The value date of the foreign currency forward contracts is March 11, 2016. The net fair value of the outstanding foreign currency forward contracts is disclosed in Note 4 Fair Value, and is recorded as a liability under other accrued liabilities in the condensed consolidated balance sheets. In the three and six months ended December 31, 2015, we recognized net unrealized losses of $0.4 million and net unrealized gains of $1.2 million, respectively, on the foreign currency forward contracts, which are recorded in selling, general, and administrative expenses in the condensed consolidated statements of income.
