Accounting Policies [Abstract] |
Organization and Summary of Significant Accounting Policies | 1. Organization and Summary of Significant Accounting Policies Organization and Basis of Presentation We are a leading worldwide developer and supplier of custom-designed user interface solutions that enable people to interact more easily and intuitively with a wide variety of mobile computing, communications, entertainment, and other electronic devices. We currently target the markets for mobile product applications, including mobile smartphones and feature phones; tablets; the personal computer, or PC, product applications market, primarily notebook and ultrabook computers; and other select electronic device markets, with our customized human interface solutions. Every solution we deliver either contains or consists of our touch-based semiconductor solution, which includes our capacitive sensing ASIC, customer-specific firmware, and software. Our original equipment manufacturer, or OEM, customers include many of the world’s largest OEMs for mobile smartphones and feature phones and most of the tier one PC OEMs. The consolidated financial statements are presented in accordance with U.S. generally accepted accounting principles, or U.S. GAAP, and 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. The fiscal years presented in this report were a 52-week period ended June 29, 2013, a 53-week period ended June 30, 2012 and a 52-week period ended June 25, 2011. 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, share-based compensation costs, provision for income taxes, deferred income tax asset valuation allowances, uncertain tax positions, tax contingencies, 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. Cash Equivalents and Investments Cash equivalents consist of highly liquid investments with original maturities of three months or less. Our non-current investments are reported at fair value, with unrealized gains and losses excluded from earnings and shown separately as a component of accumulated other comprehensive income within stockholders’ equity. We charge other-than-temporary declines in the fair value of a debt security to earnings if the decline is due to a credit loss or if we intend to or need to sell at a loss, resulting in the establishment of a new cost basis in the debt security. We charge other-than-temporary declines in the fair value of a debt security to other comprehensive income if the decline is due to a noncredit loss. We include interest earned on securities in interest income. We determine realized gains and losses on the sale of securities using the specific identification method. Our cash equivalents and investments classified as available-for-sale securities as of the end of fiscal 2013 and 2012 were as follows (in thousands):

Fair Value We measure certain financial assets and liabilities at fair value. When we measure fair value on either a recurring or nonrecurring basis, inputs used in valuation techniques are assigned a hierarchical level as follows:
| • |  | Level 1 inputs are observable inputs that reflect quoted prices for identical assets or liabilities in active markets.
| • |  | Level 2 inputs reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.
| • |  | Level 3 inputs are unobservable inputs reflecting our assumptions, which are incorporated into valuation techniques and models used to determine fair value. The assumptions are consistent with market participant assumptions that are reasonably available.
Financial assets and liabilities measured at fair value on a recurring basis, by level within the fair value hierarchy, as of the end of fiscal 2013 and 2012 were as follows (in thousands):
|  | 2013 |  |  | 2012 |
|  | Level 1 |  |  | Level 3 |  |  | Level 1 |  |  | Level 3 |
Assets |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Liabilities |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Contingent consideration liability recorded for business acquisition |  | $ | — |  |  | $ | 8,247 |  |  | $ | — |  |  | $ | 11,900 |
In connection with the acquisition of Pacinian in June 2012, we entered into a contingent consideration arrangement, and subsequently paid $5.0 million of additional consideration to the former Pacinian stockholders upon customer acceptance of a ThinTouch product. As of June 30, 2013, we owe up to $10.0 million of additional consideration to the former Pacinian stockholders based on sales of products utilizing ThinTouch technology through June 2016. We have classified the contingent consideration liability recorded for a business acquisition as a Level 3 liability, of which $8.1 million and $11.9 million is included in the non-current portion of other liabilities as of the end of fiscal 2013 and 2012, respectively, and $196,000 has been included in other current liabilities as of the end of fiscal 2013. The contingent consideration liability is estimated applying a probability-weighted discounted cash flow model with an assumed discount rate of approximately 13% as of the end of fiscal 2013. There were no Level 2 financial assets or liabilities as of the end of fiscal 2013 or 2012. Changes in fair value of our Level 3 financial assets for fiscal 2013 and 2012 were as follows (in thousands):
|  | 2013 |  |  | 2012 |
Beginning balance |  | $ | 15,321 |  |  | $ | 25,876 |
Net unrealized gain/(loss) |  |  | 4,998 |  |  |  | (522 | )
Impairment recovery of redeemed investments |  |  | — |  |  |  | 77 |
Redemptions |  |  | (3,350 | ) |  |  | (10,110 | )
Ending balance |  | $ | 16,969 |  |  | $ | 15,321 |
Changes in fair value of contingent consideration measured using significant unobservable inputs (Level 3) for fiscal 2013 and 2012 were as follows (in thousands):
|  | 2013 |  |  | 2012 |
Beginning balance |  | $ | 11,900 |  |  | $ | — |
Contingent consideration liability incurred |  |  | — |  |  |  | 11,900 |

Accretion and remeasurement |  |  | 1,347 |  |  |  | — |
Ending balance |  | $ | 8,247 |  |  | $ | 11,900 |
There were no transfers in or out of our Level 1, 2, or 3 assets or liabilities during fiscal 2013 or 2012. The fair values of our accounts receivable and accounts payable approximate their carrying values because of the short-term nature of those instruments. The fair value of our notes payable approximates carrying value in all material respects. Intangible assets, property and equipment, and goodwill are measured at fair value on a non-recurring basis if impairment is indicated. Concentration of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash equivalents, investments, and accounts receivable. Our investment policy, which is predicated on capital preservation and liquidity, limits investments to U.S. government treasuries and agency issues, taxable securities, and municipal issued securities with a minimum rating of A1 (Moody’s) or P1 (Standard and Poor’s) or equivalent. Included within our investment portfolio are investments in ARS investments, which met our investment guidelines at the time of our investment. Our ARS investments are currently not liquid as a result of continued auction failures. We sell our products to contract manufacturers that provide manufacturing services for OEMs and to some OEMs directly. We extend credit based on an evaluation of a customer’s financial condition, and we generally do not require collateral. The following customers accounted for more than 10% of our accounts receivable balance as of the end of fiscal 2013 and 2012:
|  | 2013 |  |  | 2012 |
Customer A |  |  | 27 | % |  |  | * |
Customer B |  |  | * |  |  |  | 14 | %
Customer C |  |  | * |  |  |  | 12 | %
* | Less than 10%
Other Concentrations Our products include certain components that are currently single sourced. We believe other vendors would be able to provide similar components; however, the qualification of such vendors may require start-up time. In order to mitigate any adverse impacts from a disruption of supply, we strive to maintain an adequate supply of critical single-sourced components. 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, which is generally upon shipment of the product. We accrue for estimated sales returns, incentives and other allowances at the time we recognize revenue. Our products contain embedded firmware and software that allows for further differentiation and customer integration, which together with, or consisting of, our ASIC chip delivers the essential functionality of our products and, as such, software revenue recognition guidance is not applicable. Advertising Costs Advertising costs, if any, are expensed when incurred. Allowance for Doubtful Accounts We maintain allowances for doubtful accounts for estimated losses resulting from the inability of customers to meet their financial obligations. On an ongoing basis, we evaluate the collectability of accounts receivable based on a combination of factors. In circumstances in which we are aware of a specific customer’s potential inability to meet its financial obligation, we record a specific reserve of the bad debt against amounts due. In addition, we make judgments and estimates on the collectability of accounts receivable based on our historical bad debt experience, customers’ creditworthiness, current economic trends, recent changes in customers’ payment trends, and deterioration in customers’ operating results or financial position. If circumstances change adversely, additional bad debt allowances may be required. For all periods presented, credit losses on our accounts receivable have been insignificant, and we believe that an adequate allowance for doubtful accounts has been provided. Cost of Revenue Our cost of revenue includes the cost of products shipped to our customers, which primarily includes the cost of products built to our specifications by our contract manufacturers, the cost of silicon wafers supplied by independent semiconductor wafer manufacturers, and the related assembly, package, and test costs of our die and packaged ASICs. Also included in our cost of revenue are personnel and related costs, including share-based compensation, for quality assurance and manufacturing support; logistics costs; depreciation of equipment supporting manufacturing; license amortization; inventory write-downs and losses on purchase obligations; and warranty costs. Inventories Inventories are stated at the lower of cost (first-in, first-out method) or market (estimated net realizable value) as of the end of fiscal 2013 and 2012 and consisted of the following (in thousands):
|  | 2013 |  |  | 2012 |
Raw materials |  | $ | 38,181 |  |  | $ | 26,957 |
Finished goods |  |  | 11,767 |  |  |  | 4,710 |
|  | $ | 49,948 |  |  | $ | 31,667 |
Periodically, we purchase inventory from our contract manufacturers when a customer delays its delivery schedule or cancels its order. In those circumstances in which our customer has cancelled its order and we purchase inventory from our contract manufacturers, we record a write-down, if necessary, to reduce the carrying value of the inventory purchased to its net realizable value. The effect of these write-downs is to establish a new cost basis in the related inventory, which we do not subsequently write up. We also record a liability and charge to cost of revenue for estimated losses on inventory we are obligated to purchase from our contract manufacturers when such losses become probable from customer delays or order cancellations. Property and Equipment We state property and equipment at cost less accumulated depreciation and amortization. We compute depreciation using the straight-line method over the estimated useful lives of the assets. We amortize leasehold improvements over the shorter of the lease term or the useful life of the asset. Foreign Currency 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. All of our revenue and approximately 92% of our consolidated costs are denominated in U.S. dollars. We remeasure foreign currency expenses at the weighted average exchange rate in the month that the transaction occurred. Remeasurement of monetary assets and liabilities that are not denominated in the functional currency are included currently in operating results. Foreign currency losses included in operating results for fiscal 2013, 2012, and 2011 were not material. To date, we have not undertaken hedging transactions related to foreign currency exposure. Goodwill We review the carrying value of goodwill at least annually for impairment during the last quarter of our fiscal year. The frequency of our review is dictated by events or changes in circumstances indicating that the carrying value may be impaired. Impairment of Long-Lived Assets We evaluate long-lived assets, such as property and equipment and intangible assets subject to amortization, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. We review the carrying value of indefinite-lived intangible assets for impairment at least annually during the last quarter of our fiscal year, or more frequently if we believe indicators of impairment exist. We measure recoverability of assets to be held and used by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated undiscounted future cash flows, we recognize an impairment charge in an amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the consolidated balance sheets and reported at the lower of the carrying amount or fair value less costs to sell, and would no longer be depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the consolidated balance sheets. There were no events during the fiscal year that triggered an impairment of our long-lived assets. Other Accrued Liabilities As of the end of fiscal 2013 and 2012, other accrued liabilities consisted of the following (in thousands):
|  | 2013 |  |  | 2012 |
Customer obligations |  | $ | 16,291 |  |  | $ | 13,076 |
Inventory obligations |  |  | 6,333 |  |  |  | 5,680 |
Warranty |  |  | 1,696 |  |  |  | 2,175 |
Other |  |  | 7,117 |  |  |  | 5,584 |
|  | $ | 31,437 |  |  | $ | 26,515 |
Segment Information We operate in one segment: the development, marketing, and sale of intuitive human interface solutions for electronic devices and products. Share-Based Compensation Costs We utilize the Black-Scholes option pricing model to estimate the grant date fair value of stock options granted to employees, which requires the input of highly subjective assumptions, including expected volatility and expected life. Historical and implied volatilities were used in estimating the fair value of our stock option awards. The expected life for our options was previously estimated based on historical trends since our initial public offering. In fiscal 2011, we began to grant options with a contractual life of seven years rather than 10 years and we began using the simplified method of establishing the expected life as we did not have any history of options with seven-year lives. In fiscal 2013, we began to grant options which vest over a three-year period rather than a four-year period and we continued to use the simplified method of establishing the expected life as we do not have any history of options which vest over a three year period. Changes in these inputs and assumptions can materially affect the measure of estimated fair value of our share-based compensation. Further, we estimate forfeitures for share-based awards that are not expected to vest. We charge estimated fair value less estimated forfeitures to earnings on a straight-line basis over the vesting period of the underlying awards, which is generally three to four years for our stock option and deferred stock unit, or DSU, awards, three years for our market stock unit, or MSU, awards, and up to two years for our employee stock purchase plan. Product Warranties We generally warrant our products for a period of 12 months from the date of sale and estimate probable product warranty costs 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. However, we assess the adequacy of our warranty obligations periodically and adjust the accrued warranty liability on the basis of our estimates. Changes in our warranty liability (included in other accrued liabilities) for fiscal 2013 and 2012 were as follows (in thousands):
|  | 2013 |  |  | 2012 |
Beginning accrued warranty |  | $ | 2,175 |  |  | $ | 2,984 |
Provision for product warranties |  |  | 875 |  |  |  | 1,759 |
Cost of warranty claims and settlements |  |  | (1,354 | ) |  |  | (2,568 | )
Ending accrued warranty |  | $ | 1,696 |  |  | $ | 2,175 |
Income Taxes We account for income taxes under the asset and liability method. We recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. We recognize the effect on deferred tax assets and liabilities of a change in tax rates in income in the period that includes the enactment date. We establish valuation allowances when necessary to reduce deferred tax assets to the amounts that are more likely than not to be realized. We consider the operating earnings of our foreign subsidiaries to be indefinitely invested outside the United States. Accordingly, no provision has been made for the U.S. federal, state, or foreign taxes that may result from future remittances of undistributed earnings of our foreign subsidiaries. We use a two-step approach to recognizing and measuring uncertain tax positions. The first step is to determine whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement with a taxing authority. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of highly complex tax laws. Resolution of these uncertainties in a manner inconsistent with our expectations could have a material impact on our consolidated financial position, results of operations, and cash flows. We believe we have adequately provided for reasonably foreseeable outcomes in connection with the resolution of income tax uncertainties. However, our results have in the past, and could in the future, include favorable and unfavorable adjustments to our estimated tax liabilities in the period a determination of such estimated tax liability is made or resolved, upon the filing of an amended return, upon a change in facts, circumstances, or interpretation, or upon the expiration of a statute of limitation. Accordingly, our effective tax rate could fluctuate materially from period to period. Research and Development Research and development costs are expensed as incurred.
