1. Organization and Summary of Significant Accounting Policies

Business

InvenSense, Inc. (“the Company”) was incorporated in California in June 2003 and reincorporated in Delaware in January 2004. The Company designs, develops, markets and sells Micro-Electro-Mechanical Systems (“MEMS”) sensors, such as accelerometers, gyroscopes and microphones for consumer electronics, and is dedicated to bringing the best-in-class size, performance and cost solutions to market. Targeting applications in smartphones and tablets, console and portable video gaming devices, digital still and video cameras, smart TVs (including digital set-top boxes, televisions and multi-media HDDs), navigation devices, toys, and health and fitness accessories, the Company delivers leading solutions based on its advanced multi-axis technology.

These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto for the fiscal year ended March 30, 2014 included in the Company’s Annual Report on Form 10-K filed on May 29, 2014 with the Securities and Exchange Commission (“SEC”). No material changes have been made to the Company’s significant accounting policies since the Company’s Annual Report on Form 10-K for the fiscal year ended March 30, 2014.

Certain Significant Business Risks and Uncertainties

The Company participates in the high-technology industry and believes that adverse changes in any of the following areas could have a material effect on the Company’s future financial position, results of operations, or cash flows: reliance on a limited number of primary customers to support the Company’s revenue generating activities; advances and trends in new technologies and industry standards; market acceptance of the Company’s products; development of sales channels; strategic relationships, including key component suppliers; litigation or claims against the Company based on intellectual property, patent, product, regulatory, or other factors; and the Company’s ability to attract and retain employees necessary to support its growth.

Basis of Consolidation

The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles, or GAAP, and include our accounts and the accounts of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The functional currency of each of the Company’s subsidiaries is the U.S. dollar. Foreign currency gains or losses are recorded as other income (expense), net, in the condensed consolidated statements of operations.

Fiscal Year

The Company’s fiscal year is a 52 or 53 week period ending on the Sunday closest to March 31. The Company’s most recent fiscal year (“Fiscal 2014”) ended on March 30, 2014 (“March 2014”). The second fiscal quarter in each of the two most recent fiscal years ended on September 28, 2014 (“three months ended September 28, 2014” or “September 2014”) and September 29, 2013 (“three months ended September 29, 2013” or “September 2013”), respectively, and each quarter period included 13 weeks.

Use of Estimates

The preparation of the Company’s Condensed Consolidated Financial Statements and related Notes in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and related Notes and the reported amounts of income and expenses during the reporting period. Significant estimates included in the Consolidated Financial Statements and related Notes include income taxes, inventory valuation, stock-based compensation, loss contingencies, warranty reserves, valuation of acquired assets and contingent consideration, and valuation of convertible senior notes, including the related convertible notes hedges and warrants. These estimates are based upon information available as of the date of the consolidated financial statements, and actual results could differ from those estimates.

Concentration of Credit Risk

At September 28, 2014, two customers accounted for 55% and 12% of accounts receivable. At March 30, 2014, three customers accounted for 28%, 19% and 19% of accounts receivable.

For the three months ended September 28, 2014, two customers accounted for 29% and 26% of net revenue. For the six months ended September 28, 2014, three customers accounted for 30%, 17% and 10% of net revenue. For the three months ended September 29, 2013, two customers accounted for 36% and 14% of net revenue. For the six months ended September 29, 2013, one customer accounted for 31% of net revenue.

Warranty

The Company’s warranty agreements are contract and component specific and can be for a period of up to three years after shipment for selected components. The accrual includes management’s judgment regarding anticipated rates of warranty claims and associated repair costs. The following table summarizes the activity related to product warranty liability during the six months ended September 28, 2014 and September 29, 2013:

Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares outstanding during the period, which excludes dilutive unvested restricted stock.

Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares outstanding, including unvested restricted stock, certain warrants to purchase common stock and potential dilutive shares from the dilutive effect of outstanding stock options using the treasury stock method.

The following table presents the calculation of basic and diluted net income (loss) per share:

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU No. 2014-09 provides guidance that companies will recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the payment to which a company expects to be entitled in exchange for those goods or services. The Company will be required to implement the new revenue recognition standard for the first quarter of fiscal year 2018. The Company is currently evaluating the impact on its consolidated financial statements.

2. Cash Equivalents and Available-for-sale Investments, and Fair Value of Financial Instruments

At September 28, 2014, of the $38.4 million of the Company’s cash and cash equivalents, $35.3 million was cash and $3.1 million was cash equivalents invested in money market funds and commercial paper. At September 28, 2014, $34.7 million of the $38.4 million of cash and cash equivalents were held by our foreign subsidiaries. If these funds are needed for our operations in the United States, the Company would be required to accrue and pay U.S. taxes to repatriate these funds. However, the Company’s intent is to indefinitely reinvest these funds outside of the United States, and the Company’s current plans for the foreseeable future do not demonstrate a need to repatriate them to fund U.S. operations. Additionally, as of September 28, 2014, the Company had short-term available-for-sale investments of $86.6 million and long-term available-for-sale investments of $35.0 million totaling $121.6 million. Long-term investments as of September 28, 2014 of $35.0 million had scheduled maturities between one and two years from the balance sheet date.

At March 30, 2014, of the $26.0 million of the Company’s cash and cash equivalents, $15.3 million was cash and $10.7 million was cash equivalents invested in money market funds. At March 30, 2014, $9.8 million of the $26.0 million of cash and cash equivalents were held by our foreign subsidiaries. As of March 30, 2014, the Company had short-term available-for-sale investments of $91.3 million and long-term available-for-sale investments of $128.8 million totaling $220.1 million which was held in the US entity. Long-term investments as of March 30, 2014 of $128.8 million had scheduled maturities between one and two years from the balance sheet date.

The Company applies the provisions of ASC 820-10, “Fair Value Measurements”. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. ASC 820-10 requires disclosure that establishes a framework for measuring fair value and expands disclosure about fair value measurements. The standard describes a fair value hierarchy based on three levels of inputs that may be used to measure fair value. The inputs for the first two levels are considered observable and the last is unobservable and include the following:

Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2 — Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; or

Level 3 — Unobservable inputs in which there is little or no market data, and as a result, prices or valuation techniques are employed that require inputs that are significant to the fair value measurement.

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, the Company measures certain financial assets and liabilities at fair value.

The fair values of our money market funds were derived from quoted market prices as active markets for these instruments exist. The Company chose not to elect the fair value option as prescribed by ASC 825-10-05 “Fair Value Option” for its financial assets and liabilities that had not been previously carried at fair value. Therefore, financial assets and liabilities not carried at fair value, such as accounts payable, are still reported at their carrying values.

Level 3 financial liabilities:

The following table provides a summary of changes in fair value of the Company’s contingent consideration categorized as Level 3 for the six months ended September 28, 2014:

	Six Months Ended
	September 28, 2014
	(in thousands)
Beginning balance	$	—
Add: Contingent consideration in connection with acquisitions		16,034
Ending balance	$	16,034

Contingent consideration on acquired businesses (See Note 8) was measured at fair value using Level 3 inputs as defined in the fair value hierarchy. The following table presents certain information about the significant unobservable inputs used in the fair value measurement for the contingent consideration measured at fair value on a recurring basis using significant unobservable inputs:

Description	Valuation Techniques	Significant Unobservable Inputs
Liabilities: Contingent consideration	Present value of a Probability Weighted Earn-out model using an appropriate discount rate.	Estimate of meeting the milestones.

An increase in the estimate of probability of meeting the milestones could result in a significantly higher estimated fair value of the contingent consideration liability. Alternatively, a decrease in the estimate of probability of meeting the milestones could result in a significantly lower estimated fair value of contingent consideration liability.

The fair value of contingent consideration was derived from a probability weighted earn-out model of future contingent payments. The cash payments are expected to be made upon meeting the milestones (See Note 8). The valuation of the contingent consideration was based on a collaborative effort of the Company’s engineering and finance departments, and third party valuation experts. The estimate of meeting the milestones and discount rates will be reviewed quarterly and updated as and when necessary. Potential valuation adjustments will be made to adjust the contingent consideration payments. These adjustments will be recorded in the statements of operations.

There were no transfers of assets measured at fair value between Level 1 and Level 2 during the six months ended September 28, 2014.

4. Commitments and Contingencies

Operating Lease Obligations

The Company has non-cancelable operating leases for its facilities through fiscal year 2020.

Future minimum lease payments under operating leases as of September 28, 2014 are as follows:

	Amount
	(in thousands)
Fiscal Years Ending:
2015 (remainder)	$	2,340
2016		5,878
2017		5,970
2018		5,877
2019		5,991
Beyond		6,133
Total	$	32,189

The Company’s lease agreements provide for rental payments which have certain lease incentives and graduated rental payments. As a result, the rent expense is recognized on a straight-line basis over the term of the lease. The Company’s rental expense under operating leases was approximately $1.2 million and $2.3 million for the three and six months ended September 28, 2014, respectively. The Company’s rental expense under operating leases was approximately $1.2 million and $1.8 million for the three and six months ended September 29, 2013, respectively.

Legal Proceedings

From time to time the Company is involved in litigation that the Company believes is of the type common to companies engaged in our line of business, including intellectual property and employment issues. Regardless of the merit or resolution of any such litigation, complex intellectual property litigation is generally costly and can divert the efforts and attention of our management and technical personnel.

5. Convertible Senior Notes

In November 2013, the Company issued $175.0 million aggregate principal amount of 1.75% Convertible Senior Notes due on November 1, 2018 (the “Notes”), in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933 (the “Securities Act”). The Notes offered have not been registered under the Securities Act, or applicable state securities laws or blue sky laws, and may not be offered or sold in the United States absent registration under the Securities Act and applicable state securities laws or available exemptions from the registration requirements.

The Notes are senior unsecured obligation of the Company and rank equally in right of payment with all of the Company’s existing and future senior unsecured indebtedness and are junior to any of the Company’s existing and future secured indebtedness. The Notes pay interest in cash semi-annually (May and November) at a rate of 1.75% per annum. Net proceeds received by the Company, after issuance costs, were approximately $169.3 million.

On or after August 1, 2018 until the maturity date, the Notes may be converted at the option of the holders. Holders may convert the Notes at their option prior to August 1, 2018 only under the following circumstances:

15

INVENSENSE, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1) During any calendar quarter commencing after the calendar quarter ending on March 31, 2014 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

2) During the five business day period after any five consecutive trading day period in which the “trading price” per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; or

3) Upon the occurrence of specified corporate events, including if there is a fundamental change.

Upon conversion, the Company will pay cash up to the aggregate principal amount of the Notes to be converted and pay or deliver cash, shares of its own common stock or a combination of cash and shares of its own common stock, at the Company’s election, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the notes being converted.

The conversion rate is initially 45.683 shares per $1,000 principal amount of the Notes (equivalent to an initial conversion price of approximately $21.89 per share of common stock), subject to certain adjustments.

The Notes are not redeemable by the Company prior to the maturity date. At the event of default or fundamental change, the principal amount of the notes plus accrued and unpaid interest may become due immediately at the Note holders’ option.

The Company used and plans to use the net proceeds of approximately $169.3 million from the offering of the Notes (after the issuance costs) for general corporate purposes, including to replace cash used for business acquisitions (see Note 8), for the cost of the Note hedge transactions (see below) and for capital expenditures and working capital. However, the Company has not designated with certainty all of the particular uses for the net proceeds from the Notes.

The Company separately accounts for the liability and equity components of the Notes. The initial debt component of the Notes was valued at $135.7 million based on the contractual cash flows discounted at an appropriate comparable market non-convertible debt borrowing rate at the date of issuance of 7.3%, with the equity component representing the residual amount of the proceeds of $39.3 million which was recorded as a debt discount. The issuance costs were allocated pro-rata based on the relative initial carrying amounts of the debt and equity components, including the Note hedges and warrants transactions described below. As a result, $2.5 million of the issuance costs was allocated to the equity component of the Notes, $3.0 million of issuance costs paid to the initial purchaser was accounted for as a debt discount and $0.25 million of the issuance costs was classified as other non-current assets. The debt discount and the issuance costs allocated to the debt component are amortized as additional interest expense over the term of the Notes using the effective interest method. As of September 28, 2014 the remaining amortization period of the debt discount and the issuance costs is 4.1 years. The effective interest rate of the Notes is 7.84% per annum (1.75% coupon rate plus 6.09% of non-cash accretion expense).

Convertible Notes Hedges and Warrants

Concurrent with the issuance of the Notes on November 6 and 7, 2013, the Company purchased call options for its own common stock to hedge the Notes (the “Note Hedge”) and sold call options for its own common stock (the “Warrants”). The Note Hedges and Warrants transactions are structured to reduce the potential future economic dilution associated with the conversion of the Notes and are excluded from the computation of diluted earnings per share for each period presented, as the Company’s average stock price during each period is less than the conversion price.

The Note Hedges — On November 6 and 7, 2013, the Company purchased call options from a counterparty for an aggregate price of approximately $39.1 million, which gives the Company the right to buy from the counterparty up to approximately 8.0 million shares of the Company’s common stock at a price of $21.89 per share, subject to adjustments. The Note Hedge is exercisable upon conversion of the Note for a number of shares equal to the product of 0.045683 and amount of the converted Note. Upon exercise of the Note Hedge the Company will receive from the counterparty cash, shares of Company’s common stock, or a combination thereof, equal to the amount by which the market price per share of the Company’s common stock exceeds $21.89 during the applicable valuation period. By the Note Hedge terms the Company will receive cash and shares in a combination that offsets share dilution caused by conversion of the Note.

Warrants — On November 6 and 7, 2013, the Company sold call options to the same counterparty for approximately $25.6 million, which gives the counterparty the right to buy from the Company up to approximately 8.0 million shares of the Company’s common stock at an exercise price of $28.66 per share, subject to adjustments, on a series of days commencing on February 1, 2019 and ending May 13, 2019. Upon exercise of the Warrants, the Company has the option to deliver cash or shares of its common stock equal to the difference between the market price on the exercise date and the strike price of the warrants. Upon exercise of the Warrants, the Company will pay to the Initial Purchaser cash, shares of Company’s common stock, or a combination thereof (at the Company’s choice), equal to the amount by which the market price per share of the Company’s common stock exceeds $28.66 during the applicable valuation period.

The Note Hedges and Warrants above are classified in stockholders’ equity in the Company’s consolidated balance sheets.

The convertible notes issued by the Company in November 2013 are shown in the accompanying consolidated balance sheets at their original issuance value, net of unamortized discount, and are not marked to market each period. The approximate fair value of the convertible notes as of September 28, 2014 was $195.4 million. The fair value of the convertible notes was determined using quoted market prices for similar securities, which, due to limited trading activity, are considered Level 2 in the fair value hierarchy.

6. Stockholders’ Equity

Stock Plans

In July 2011, the Company’s Board of Directors and its stockholders approved the establishment of the 2011 Stock Incentive Plan (the “2011 Plan”). The 2011 Plan provides for annual increases in the number of shares available for issuance there under on the first business day of each fiscal year, beginning with the Company’s fiscal year following the year of this offering, equal to four percent (4%) of the number of shares of the Company’s common stock outstanding as of such date, which resulted in an annual increase of 3.5 million shares for fiscal year 2015.

Under the Company’s 2004 Stock Incentive Plan and 2011 Stock Incentive Plan (the “Plans”), the Board of Directors may grant either incentive stock options, nonqualified stock options, or stock awards to eligible persons, including employees, nonemployees, members of the Board of Directors, consultants and other independent advisors who provide services to the Company.

Incentive stock options may only be granted to employees and at an exercise price of no less than 100% of fair value on the date of grant. Nonqualified stock options may be granted at an exercise price of no less than 100% of fair value on the date of grant. For owners of more than 10% of the Company’s common stock, options may only be granted for an exercise price of not less than 110% of fair value, and these options generally expire 10 years from the date of grant. Stock options may be exercisable immediately but are subject to repurchase. Stock options vest over the period determined by the Board of Directors, generally four years.

Stock option activities of the Company under the Plans are as follows (in thousands, except per share amounts):

	Options Available for Grant			Options Issued and Outstanding			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (In Years)		Aggregate Intrinsic Value
Outstanding — March 30, 2014		12,595			8,276		$	10.37		7.87	$	102,072

Valuation of Stock-Based Awards

The Company applies the provisions of ASC 718-10 “Compensation — Stock Compensation” which establishes the accounting for stock-based awards based on the fair value of the award measured at grant date. Accordingly, stock-based compensation cost is recognized in the condensed consolidated statements of operations as a component of both cost of revenues and operating expenses over the requisite service period. ASC 718-10 requires tax benefits in excess of compensation cost to be reported as a financing cash flow rather than as a reduction of taxes paid. The determination of the fair value of stock-based payment awards on the date of grant using the Black-Scholes option pricing model is affected by the volatilities of a peer group of companies based on industry, stage of life cycle, size and financial leverage, actual and projected employee stock option exercise behaviors, risk-free interest rate and expected dividends. Variables to be determined include expected volatility, estimated term and risk-free interest rate.

The aggregate intrinsic value of the stock options exercised during the three and six months ended September 28, 2014 was $11.2 million and $14.1 million respectively. The aggregate intrinsic value of the stock options exercised during the three and six months ended September 29, 2013 was $11.3 million and $22.8 million respectively. The aggregate intrinsic value was calculated as the difference between the exercise price of the stock options and the estimated fair market value of the underlying common stock at the date of exercise.

The number of options expected to vest takes into account an estimate of expected forfeitures. The remaining unamortized stock-based compensation expense, reduced for estimated forfeitures and related to non-vested options, was $18.3 million, and $20.7 million at September 28, 2014 and September 29, 2013, respectively, and will be amortized over a weighted-average remaining period of approximately 2.6 and 3.1 years, respectively. Total unrecognized expense will be adjusted for future changes in estimated forfeitures.

The Company used the following weighted-average assumptions in determining stock-based compensation expense for options granted in the three and six months ended September 28, 2014 and September 29, 2013.

	Three Months Ended						Six Months Ended
	September 28, 2014			September 29, 2013			September 28, 2014			September 29, 2013

Restricted stock units and restricted stock granted to employees are generally subject to the employee’s continued service to the Company over that period. The fair value of restricted stock units and restricted stock is determined using the fair value of the Company’s common stock on the date of the grant. Compensation expense is generally recognized on a straight-line basis over the requisite service period of each grant adjusted for estimated forfeitures. At September 28, 2014, there was approximately $43.6 million of total unrecognized compensation cost related to restricted stock units and restricted stock, which the Company expects to recognize over a weighted-average period of 3.2 years. The weighted-average grant-date fair value per share of restricted stock units and restricted stock awarded in the six months ended September 28, 2014 and September 29, 2013 was $21.84 and $14.69, respectively.

Common Stock

As of September 28, 2014 and March 30, 2014, common stock reserved for future issuance was as follows:

2013 Employee Stock Purchase Plan

Under the 2013 Employee Stock Purchase Plan, effective September 13, 2013, (the “Purchase Plan”), eligible employees may apply accumulated payroll deductions, which may not exceed 10% of an employee’s compensation, to the purchase of shares of the Company’s common stock at periodic intervals. The purchase price of stock under the Purchase Plan is equal to 85% of the lower of (i) the fair market value of the Company’s common stock on the first day of each offering period, or (ii) the fair market value of the Company’s common stock on the purchase date (as defined in the Purchase Plan). Each offering period consists of one purchase period of approximately six months duration.

An aggregate of 400,000 shares of common stock were reserved for issuance to employees under the Purchase Plan. As of September 28, 2014, 61,000 shares had been purchased.

Stock-Based Compensation Expense

Total employee stock-based compensation costs for the Company’s stock plans for the three and six months ended September 28, 2014 and September 29, 2013 are as follows:

7. Income Taxes

In the three and six months ended September 28, 2014, the Company recorded an income tax provision of $0.6 million and $0.9 million respectively. In the three and six months ended September 30, 2013, the Company recorded an income tax provision of $1.9 million and $3.8 million respectively. The Company’s estimated 2015 effective tax rate differs from the U.S. statutory rate primarily due to profits earned in jurisdictions where the tax rate is lower than the U.S. tax rate partially offset by the unfavorable effects of non-deductible stock-based compensation expense.

The Company files U.S. federal income tax returns as well as income tax returns in California, Massachusetts and various foreign jurisdictions. The Company has not provided for U.S. federal income and foreign withholding taxes on undistributed earnings from non-U.S. operations as of September 28, 2014 because such earnings are to be reinvested indefinitely.

The Company has recorded $10.5 million of uncertain tax positions within “Other long-term liabilities” on the condensed consolidated balance sheet as at September 28, 2014. The Company does not expect any significant increases or decreases to its unrecognized tax benefits within the next twelve months. While management believes that the Company has adequately provided for all tax positions, amounts asserted by tax authorities could be greater or less than the recorded position. Accordingly, the Company’s provisions on federal, state and foreign tax-related matters to be recorded in the future may change as revised estimates are made or the underlying matters are settled or otherwise resolved.

The Company’s tax year from 2003 and onwards could be subject to examinations by tax authorities in one or more tax jurisdictions. The Internal Revenue Service (the “IRS”) is currently examining the fiscal years 2011 through 2013. In addition, the Company is subject to audits by state, local, and foreign tax authorities. Management believes that adequate provisions have been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs.

8. Business Combination

Movea S.A

On July 22, 2014, the Company acquired 100% equity interest of Movea, a company formed under the laws of France, and a leading provider of software for ultra-low power location, activity tracking and context sensing. The acquisition of Movea further scales the Company’s leadership in motion software.

The Company paid $60.9 million in cash as consideration for the acquisition and could pay an additional $13.0 million in cash contingent upon the achievement of certain milestones within one year of the acquisition.

In addition, the Company, under its 2011 Stock Incentive Plan granted restricted stock units (RSU), with a fair value of $6.6 million, to certain Movea employees. The RSUs will vest over a 5 year requisite service period.

The purchase price includes contingent considerations of (i) $8.0 million payable in cash to the former Movea shareholders upon a design win with a major smartphone manufacturer within one year of closing date, and (ii) $5.0 million payable in cash to the former Movea shareholders upon a specific product development milestone by December 2014. The fair value of the contingent consideration of $8.4 million was derived from a probability weighted earn-out model of future contingent payments.

The purchase price exceeded the fair value of the net tangible and identifiable intangible assets acquired and, as a result, the Company recorded goodwill in connection with this transaction. The acquisition will provide assembled workforce and synergy with other of the Company’s offerings. These factors primarily contributed to a purchase price that resulted in goodwill.

The following table presents certain information on acquired identifiable intangible assets related to the Movea acquisition:

	Estimated Fair Value (in thousands)		Estimated Useful Life (in years)
Developed technology	$	7,200		5

The fair value of developed technology was determined using a cost approach, which includes an estimate of time and expenses required to recreate the intangible asset. The fair value of developed technology was capitalized as of the acquisition date and will be amortized using a straight-line method to cost of revenue over the estimated useful life of 5 years.

Trusted Positioning, Inc.

On August 29, 2014, the Company completed the acquisition of Trusted Positioning, Inc., (“TPI”), a Canadian corporation, which is an indoor/outdoor positioning software company with the vision to provide ‘Positioning Everywhere’. The acquisition of TPI, particularly its advanced location tracking software, strengthens the Company’s position as a provider of intelligent sensor System on Chips (SoC) for the fast growing mobile market.

The Company’s acquisition of TPI was completed through a step acquisition. In fiscal 2014, the Company made investments totaling $0.3 million to own approximately 4.57% of TPI’s outstanding common stock. On August 29, 2014, the Company purchased the remaining outstanding common stock of TPI for a total consideration of $26.1 million. The total purchase price, as presented in the table below, consists of (i) cash of $11.5 million (ii) issuance of 236,000 shares of the Company’s common stock with a fair value of $5.7 million (iii) contingent considerations with a combined fair value of $7.6 million payable upon TPI’s achievement of certain product development milestones, and (iv) initial investments with a fair value of $1.2 million.

In addition, the Company, under its 2011 Stock Incentive Plan, granted equity awards (restricted stock units and stock options), to certain TPI employees with an aggregate fair value of $5.0 million. The equity awards will vest over a 5 year requisite service period.

The table below is a summary of the preliminary purchase price allocation for the 100% equity interest of the fair value of assets acquired and liabilities assumed in connection with the acquisition of TPI (in thousands):

Cash consideration	$	11,499
Issuance of common stock		5,703

The fair value of developed technology was determined using a cost approach, which includes an estimate of time and expenses required to recreate the intangible asset. The fair value of developed technology was capitalized as of the acquisition date and will be amortized using a straight-line method to cost of revenue over the estimated useful life of 5 years.

In connection with the acquisition of TPI, the Company recorded a non-cash gain of approximately $0.9 million resulting from the difference between carrying value of its initial investments in TPI of $0.3 million and fair value of such investments of $1.2 million, as of the acquisition date. This non-cash gain is recorded in “Other income, net” on the Condensed Consolidated Statement of Operations.

MEMS Microphone Business of Analog Devices, Inc.

In the third quarter of fiscal 2014, the Company acquired certain assets relating to Analog Devices, Inc. (“ADI”) MEMS microphone business for a purchase price of $100 million in cash, of which the Company is entitled to certain contingent future expense reimbursements of approximately $2.2 million. The Company also agreed to a contingent cash payment of up to $70.0 million payable upon the achievement of certain revenue performance targets within one year of the transaction close date. Due to a low probability of achieving the revenue targets, the fair value of the contingent consideration is estimated to be zero in the purchase price allocation described below. ADI licensed certain technology related to the MEMS microphone business to the Company on a royalty-free, worldwide basis, and provides certain transition services to the Company following the closing.

The strategic rationale for the acquisition was to accelerate the Company’s audio roadmap and complement its current MEMS System on Chip product offerings at existing mobile, gaming and wearable device customers, while gaining entry into new markets. The acquisition expands the Company’s patent portfolio and existing tier one customer base, which includes major OEM brands worldwide.

The allocation of the purchase price of the assets acquired and liabilities assumed based on their fair values was as follows:

	Total Amount
	(in thousands)
Inventories	$	5,107
Property and equipment, net		4,339
Intangible assets:
Developed technology		28,520
In-Process Research & Development		7,330
Customer Relationships		1,560
Goodwill		50,952
Total assets acquired	$	97,808
Total purchase price (net of $2.2 million of contingent expense reimbursements)		97,808

The fair value of intangible assets of $37.4 million has been allocated to the following three asset categories: 1) developed technology, 2) in-process research & development and 3) customer relationships. Developed technology and customer relationships are amortized on a straight line basis over the estimated useful life of the assets.

9. Goodwill and Purchased Intangible Assets

Purchased intangible assets subject to amortization consist primarily of developed technology and customer relationships and are reported net of accumulated amortization. Developed technology and customer relationships are amortized on a straight line basis over the estimated useful life of the assets. In-process research and development is assessed for impairment until the development is completed and products are available for sale. The Company expects to complete the in-process research and development projects at various dates during fiscal year 2015 at which time amortization will commence. During the three months ended September 28, 2014, the Company recorded $0.8 million of impairment on in-process research and development on one of the ADI acquisition projects.

Overview

Business Overview

We are the pioneer and a global market leader in devices for the motion interface market that detect and track an object’s motion in three-dimensional space. We entered the audio sensor (microphone) markets through the acquisition of the MEMS Microphone product line of Analog Devices, Inc., in fiscal 2014. In the second quarter of fiscal 2015, we acquired Movea, a leading provider of software for ultra-low power location, activity tracking and context sensing and Trusted Positioning, Inc. (TPI), an indoor/outdoor positioning software company.

Our MotionTracking devices and audio products combine micro-electro-mechanical system (MEMS) motion sensors, such as accelerometers, gyroscopes, microphones and compasses, with mixed-signal integrated circuits (ICs) and proprietary algorithms and firmware that intelligently process, synthesize and calibrate the output of sensors for use by software applications via an application programming interface (API). Our devices are differentiated by their small form factor, high level of integration, performance, reliability and cost effectiveness. While our solutions have broad applicability, we currently target consumer electronics applications such as smartphones and tablets, console and portable video gaming devices, digital still and video cameras, smart TVs (including digital set-top boxes, televisions and multi-media HDDs), navigation devices, industrial sensors, toys, and health and fitness accessories. We utilize a fabless model, leveraging current CMOS and MEMS foundries and semiconductor packaging supply chains.

Our current strategy is to continue targeting the consumer electronics market with integrated MotionTracking and audio devices that meet or exceed the performance and cost requirements of consumer electronics manufacturers, are easy to integrate and set industry performance benchmarks. Our ability to secure new customers depends on winning competitive processes, known as design wins. These selection processes are typically lengthy, and, as a result, our sales cycles will vary based on the market served, whether the design win is with an existing or a new customer and whether our product being designed into our customer’s device is a first generation or subsequent generation product. Because the sales cycle for our products is long, we can incur design and development support expenditures in circumstances where we do not ultimately recognize any net revenue. We do not receive long-term purchase commitments from any of our customers, all of whom purchase our products on a purchase

27

order basis. While product life cycles in our target market vary by application, once one of our solutions is incorporated into a customer’s design, we believe that it will likely remain a component of the customer’s product for its life cycle because of the time and expense associated with redesigning the product or substituting an alternative solution. The trend is also supported by the increased likelihood that once a customer introduces one of our products into one of their devices, we believe they are likely to introduce it into others. Additionally, once a customer introduces one of our lower functionality sensors into their platforms, we believe they are more likely to adopt our more advanced integrated MotionTracking and audio devices.

Net Revenue

We derive our net revenue from sales of our MotionTracking and audio devices. We primarily sell our products through our worldwide sales organization to manufacturers of consumer electronics devices from whom we have secured a design win. These manufacturers of consumer electronics devices are categorized as our customers. The sale may be executed directly with the manufacturer or via the manufacturer’s supply chain to their designated contract manufacturer. We also sell our products through an indirect channel of distributors that fulfill orders for our products from manufacturers of consumer electronics devices, original design manufacturers and contract manufacturers.

Net revenue	$	90,195	$	70,941	$	156,876	$	126,851

Net revenue increased by $19.3 million, or 27% in the second quarter of fiscal 2015 and increased by $30.0 million, or 24%, in the first half of fiscal 2015 compared to the corresponding periods of fiscal 2014. The increases in net revenue were primarily due to higher volume shipments, partially offset by lower per unit average selling prices. Total unit shipments increased by 59% and 54% in the three and six months ended September 28, 2014, respectively. Our overall average unit selling price for the three and six months ended September 28, 2014 decreased 20% as a result of the change in our product mix and declines in average selling prices. We expect a continued trend of declining unit average selling prices for our products during their life cycles.

For the three months ended September 28, 2014, two customers each accounted for 29% (Samsung) and 26% (Apple) of total net revenue. For the six months ended September 28, 2014, three customers each accounted for 30% (Samsung), 17% (Apple) and 10% (LG) of total net revenue. For the three months ended September 29, 2013, two customers each accounted for 36% (Samsung) and 14% (Nintendo) of total net revenue. For the six months ended September 29, 2013, one customer accounted for 31% (Samsung) of total net revenue.

We report revenue by geographic region based upon the location of the headquarters of our customers. We primarily sell our products directly to customers and distributors in Asia and North America. We believe that a significant portion of our net revenue will continue to come from sales to customers located in Asia, where most of the manufacturers of consumer electronics devices that use and may in the future use our products are located. As a result of this regional customer concentration, we may be subject to economic and political events and other developments that impact our customers in Asia. For more information, see the section titled “Risk Factors — Our business, financial condition and results of operations could be adversely affected by the political and economic conditions of the countries in which we conduct business”, referred to under Item 1A of Part I in our Annual Report on Form 10-K filed on May 29, 2014 with the SEC.

Gross Profit and Gross Margin

Gross profit is the difference between net revenue and cost of revenue and gross margin is gross profit as a percentage of sales.

	Three Months Ended						Six Months Ended
(in thousands)	September 28, 2014			September 29, 2013			September 28, 2014			September 29, 2013
Gross profit	$	31,341		$	36,577		$	62,517		$	65,896
% of net revenue		35	%		52	%		40	%		52	%

Gross profit decreased by $5.2 million, or 14%, in the second quarter of fiscal 2015 and decreased by $3.4 million, or 5%, in the first half of fiscal 2015 compared to corresponding periods of fiscal 2014. In the second quarter and in the first half of fiscal 2015, gross profit as a percentage of sales, or gross margin, decreased significantly due to a $7.4 million inventory charge largely related to excess and obsolete inventories and a shift in revenue mix towards lower margin, high volume customers.

We expect gross margins to fluctuate during future periods due to changes in product mix, average unit selling prices, manufacturing costs, manufacturing yields, amortization of acquired intangible assets, levels of inventory valuation and excess reserves recorded, if any, and levels of product demand.

Research and Development

Research and development expense primarily consists of personnel related expenses (including employee cash compensation and benefits, and stock-based compensation), intellectual property license costs, reference design development

29

costs, development testing and evaluation costs, depreciation expense and allocated occupancy costs. Research and development activities include the design of new products, refinement of existing products and processes and design of test methodologies, including hardware and software to ensure compliance with required specifications. All research and development costs are expensed as incurred. We expect our research and development expenses to increase, in absolute dollar terms, to expand our product offerings and enhance existing products.

Research and development expense increased by $11.8 million, or 120%, in the second quarter of fiscal 2015 compared to the corresponding period of fiscal 2014. The increase in research and development expense were primarily attributable to a $4.8 million increase in employee cash compensation and benefits costs due to an increase in the number of employees, a $2.3 million increase in engineering supplies, a $2.0 million increase in stock-based compensation expense due to an increase in the number of employees, $0.9 million increase in IT and infrastructure expenses, and a $1.1 million increase in outside services.

Research and development expense increased by $23.1 million, or 129%, in the first half of fiscal 2015 compared to the corresponding period of fiscal 2014. The increase in research and development expense was primarily attributable to a $8.3 million increase in employee cash compensation and benefits costs due to an increase in the number of employees, a $5.4 million increase in engineering supplies, a $4.4 million increase in stock-based compensation expense due to an increase in the number of employees, $2.0 million increase in IT and infrastructure expenses, and a $1.8 million increase in outside services.

Selling, General and Administrative

Selling, general and administrative expense primarily consists of personnel related expenses (including employee cash compensation and benefits, and stock-based compensation), sales commissions, field application engineering support, travel costs, professional and consulting fees, legal fees, depreciation expense and allocated occupancy costs. We expect selling, general and administrative expenses to increase on an absolute basis in the future as we, hire personnel to expand our sales, marketing, finance, legal and other administrative personnel and pay the costs associated with litigation, if any.

Selling, general and administrative expense increased by $3.2 million, or 28%, in the second quarter of fiscal 2015 compared to the corresponding period of fiscal 2014. The increase was primarily attributable to a $1.2 million increase in stock-based compensation expense and a $1.9 million increase in employee cash compensation and benefits costs due to an increase in our workforce. Selling, general and administrative headcount was 149 at September 28, 2014 and 111 at September 29, 2013. Additions to headcount primarily supported expansion of new product and growth in business.

Selling, general and administrative expense increased by $7.9 million, or 39%, in the first half of fiscal 2015 compared to the corresponding period of fiscal 2014. The increase was primarily attributable to a $3.2 million increase in stock-based compensation expense due to an increase in the number of employees and a change in estimate of our stock award forfeiture rate, a $1.5 million increase in IT and infrastructure costs and a $3.1 million increase in employee cash compensation and benefits costs due to an increase in our workforce.

Other income, net increased by $1.0 million, or 471%, for the three months and increased by $1.1 million, or 374%, for the six months ended September 28, 2015 compared to the corresponding period of 2014. The increases in other income were primarily due to gain on equity investment in TPI of $0.9 million.

Income Tax Provision

% of income (loss) before income tax		(10	)%		13	%		(8	)%		14	%

In the three and six months ended September 28, 2014, we recorded an income tax provision of $0.6 million and $0.9 million, respectively. In the three and six months ended September 28, 2013, we recorded an income tax provision of $1.9 million and $3.8 million, respectively. The provision for income taxes for the three and six months ended September 28, 2014 differs from the U.S. statutory tax rate of 35% due primarily to the tax impact of earnings from foreign operations, and non-deductibility of certain share-based compensation. Earnings in countries where tax rates are lower than the U.S. notional rate contributed to the majority of the difference between the rate of our tax provision and the U.S. statutory tax rate. The effective tax rate for the six months ended September 28, 2014, compared to the same period in fiscal year 2013, is attributable to the federal research and development tax credit not being extended as of September 28, 2014, while the September 29, 2013 effective tax rate includes both the 2013 federal research and development credit and retroactive inclusion of the 2012 federal research and development tax credit.

Included in our gross unrecognized tax benefits balance of $13.0 million at September 2014 are $10.5 million of tax positions which would affect income tax expense if recognized. As of September 28, 2014, approximately $2.5 million of unrecognized tax benefits would be offset by a change in valuation allowance. Due to the high degree of uncertainty regarding the settlement of these liabilities, we are unable to estimate the year in which the future cash flows may occur. As a result, these amounts are not included in the tables above.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements and the related notes included elsewhere in this Quarterly Report on Form 10-Q are prepared in accordance with accounting principles generally accepted in the United States. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, net revenue, costs, and expenses, and any related disclosures. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Changes in accounting estimates are reasonably likely to occur from period to period. Accordingly, actual results could differ significantly from the estimates made by our management. We evaluate our estimates and assumptions on an ongoing basis. To the extent that there are material differences between these estimates and our actual results, our future financial statement presentation, financial condition results of operations and cash flows will be affected.

We believe that the assumptions and estimates associated with income taxes, inventory valuation, and stock-based compensation have the greatest potential impact on our condensed consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates.

There have been no material changes to the our critical accounting policies and estimates as compared to the critical accounting policies and estimates described in our Annual Report on Form 10-K filed with the SEC on May 29, 2014.

Liquidity and Capital Resources

As of September 28, 2014, we had $160.0 million of cash, cash equivalents and investments. We believe our current cash, cash equivalents and investments will be sufficient to satisfy our liquidity requirements for the next 12 months. Our liquidity may be negatively impacted as a result of a decline in sales of our products due to a decline in our end markets, decrease in sales of our customers’ products in the market, or adoption of competitors’ products. Additionally, $34.7 million of the $38.4 million of cash and cash equivalents was held by our foreign subsidiaries as of September 28, 2014. If these funds are needed for our operations in the United States, we would be required to accrue and pay U.S. taxes to repatriate these funds. However, our intent is to indefinitely reinvest these funds outside of the United States, and our current plans do not demonstrate a need to repatriate them to fund our U.S. operations.

Our primary uses of cash are to fund operating expenses, purchases of inventory, the acquisition of property and equipment and to pursue strategic investments or acquisitions if opportunities arise. Cash used to fund operating expenses excludes the impact of non-cash items such as depreciation, amortization and stock-based compensation and is impacted by the timing of when we pay these expenses as reflected in the change in our outstanding accounts payable and accrued expenses.

Our primary sources of cash are cash receipts on accounts receivable from our shipment of products to customers and distributors. Aside from the growth in amounts billed to our customers, net cash collections of accounts receivable are impacted by the efficiency of our cash collections process, which can vary from period to period depending on the payment cycles of our major customers and distributors.

The change in cash and cash equivalents for the six months ended September 28, 2014 and 2013 was as follows:

	Six Months Ended
(in thousands)	September 28, 2014			September 29, 2013
Net cash provided by (used in) operating activities	$	(2,749	)	$	16,457
Net cash provided by (used in) investing activities		9,458			(9,953	)
Net cash provided by financing activities		5,690			10,836
Net increase (decrease) in cash and cash equivalents	$	12,399		$	17,340

Net Cash Provided by (Used In) Operating Activities

Net cash used in operating activities for the six months ended September 28, 2014 of $2.7 million is primarily due to a net loss of $11.7 and a net increase in operating assets and liabilities of $16.8 million, partially offset by non-cash expenses of $25.7 million.

32

The net increase in operating assets and liabilities of $16.8 million consisted primarily of increases in “Accounts receivable” of $27.3 million, “ Inventories” of $2.0 million and “Other assets” of $1.1 million, partially offset by increases in “Accounts payable” of $5.4 million and “Accrued liabilities” of $8.1 million. The increase in “Amounts receivable” is primarily attributable to an increase in net revenue.

The non-cash expenses of $25.7 million consisted primarily of depreciation and amortization of $7.2 million and stock-based compensation of $14.6 million and non-cash interest expense of $3.7 million.

Net cash provided by operating activities for the six months ended September 29, 2013 of $16.5 million primarily reflected net income of $23.9 million and non-cash expenses of $7.7 million, partially off-set by a net change in operating assets and liabilities of $15.2 million consisting primarily of an increase in “Inventories” of $14.7 million, and “Accounts receivable” of $5.5 million, partially off-set by an increase in “Accrued liabilities” of $4.8 million. Non-cash expenses of $7.7 million consisted primarily of stock-based compensation of $6.2 million and depreciation and amortization of $1.5 million. The $14.7 million increase in “Inventories” was attributable to increased production to meet future demand. The $5.5 million increase in “Accounts receivable” principally relates to increased sales associated with an upward trend in demand in September 29, 2013 compared with March 2013. The $4.8 million increase in “Accrued liabilities” is due primarily to higher accrued legal and payroll related expenses.

Net Cash Provided By (Used In) Investing Activities

Net cash provided by investing activities in the six months ended September 28, 2014 of $9.5 million primarily from the sale and maturity of available-for-sale investments of $98.5 million, partially offset by cash paid for acquisitions of $71.4 million (net of cash acquired), and purchase of property and equipment of $17.6 million.

Net cash used in investing activities in the six months ended September 29, 2013 of $10.0 million primarily reflected the purchase of available-for-sale investments of $46.3 million and the purchase of property and equipment of $9.8 million, partially off-set by the sale and maturity of available-for-sale investments of $46.2 million.

Net Cash Provided by Financing Activities

Net cash provided by financing activities in the six months ended September 28, 2014 of $5.7 million resulted primarily from the proceeds from the issuance of common stock on stock options exercises and ESPP purchases.

Net cash provided by financing activities in the six months ended September 29, 2013 of $10.8 million resulted primarily from proceeds from the issuance of common stock of $7.6 million and excess tax benefit from stock-based compensation of $3.2 million.

Off Balance Sheet Arrangements

As part of our ongoing business, we do not participate in transactions that generate relationships with unconsolidated entities of financial partnerships, such as entities often referred to as structured finance or special purpose entities, or SPEs, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As of September 28, 2014, we were not involved in any unconsolidated SPE transactions

Contractual Obligations

The following table summarizes our outstanding contractual obligations as of September 28, 2014:

	Payments Due by Period
	Total		Less Than 1 Year		1-3 Years		3-5 Years		More Than 5 Years
	(in thousands)
Convertible senior notes obligations	$	175,000	$	—	$	—	$	175,000	$	—
Interest on convertible senior notes obligations		12,526		2,291		5,932		4,303
Operating lease obligations		32,189		2,340		11,848		11,868		6,133
Purchase obligations		74,270		74,270		—		—		—
Total contractual obligations	$	293,985	$	78,901	$	17,780	$	191,171	$	6,133

33

Convertible senior notes and interest on convertible senior notes obligations relate to the convertible senior notes issued in November 2013. See Note 5 to the Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q for a full description of the convertible senior notes.

Operating leases consist of contractual obligations from agreements for non-cancelable office space.

Purchase obligations consist of the minimum purchase commitments made to contract manufacturers.

Included in our gross unrecognized tax benefits balance of $13.0 million at September 2014 are $10.5 million of tax positions which would affect income tax expense if recognized. As of September 2014, approximately $2.5 million of unrecognized tax benefits would be offset by a change in valuation allowance. Due to the high degree of uncertainty regarding the settlement of these liabilities, we are unable to estimate the year in which the future cash flows may occur. As a result, these amounts are not included in the tables above.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

For quantitative and qualitative disclosures about market risk affecting InvenSense, see “Quantitative and Qualitative Disclosures About Market Risk” in Item 7A of Part II of our Annual Report on Form 10-K for the fiscal year ended March 30, 2014. Our exposure to market risk has not changed materially since March 30, 2014.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on such evaluation, our principal executive officer and principal financial officer have concluded that as of such date, our disclosure controls and procedures were effective.

Changes in Internal Control

There were no changes in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the period covered by this Quarterly Report on Form 10-Q that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations of Internal Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Cash Equivalents and Available-for-sale Investments, and Fair Value of Financial Instruments

2. Cash Equivalents and Available-for-sale Investments, and Fair Value of Financial Instruments

At September 28, 2014, of the $38.4 million of the Company’s cash and cash equivalents, $35.3 million was cash and $3.1 million was cash equivalents invested in money market funds and commercial paper. At September 28, 2014, $34.7 million of the $38.4 million of cash and cash equivalents were held by our foreign subsidiaries. If these funds are needed for our operations in the United States, the Company would be required to accrue and pay U.S. taxes to repatriate these funds. However, the Company’s intent is to indefinitely reinvest these funds outside of the United States, and the Company’s current plans for the foreseeable future do not demonstrate a need to repatriate them to fund U.S. operations. Additionally, as of September 28, 2014, the Company had short-term available-for-sale investments of $86.6 million and long-term available-for-sale investments of $35.0 million totaling $121.6 million. Long-term investments as of September 28, 2014 of $35.0 million had scheduled maturities between one and two years from the balance sheet date.

At March 30, 2014, of the $26.0 million of the Company’s cash and cash equivalents, $15.3 million was cash and $10.7 million was cash equivalents invested in money market funds. At March 30, 2014, $9.8 million of the $26.0 million of cash and cash equivalents were held by our foreign subsidiaries. As of March 30, 2014, the Company had short-term available-for-sale investments of $91.3 million and long-term available-for-sale investments of $128.8 million totaling $220.1 million which was held in the US entity. Long-term investments as of March 30, 2014 of $128.8 million had scheduled maturities between one and two years from the balance sheet date.

The Company applies the provisions of ASC 820-10, “Fair Value Measurements”. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. ASC 820-10 requires disclosure that establishes a framework for measuring fair value and expands disclosure about fair value measurements. The standard describes a fair value hierarchy based on three levels of inputs that may be used to measure fair value. The inputs for the first two levels are considered observable and the last is unobservable and include the following:

Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2 — Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; or

Level 3 — Unobservable inputs in which there is little or no market data, and as a result, prices or valuation techniques are employed that require inputs that are significant to the fair value measurement.

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, the Company measures certain financial assets and liabilities at fair value.

The fair values of our money market funds were derived from quoted market prices as active markets for these instruments exist. The Company chose not to elect the fair value option as prescribed by ASC 825-10-05 “Fair Value Option” for its financial assets and liabilities that had not been previously carried at fair value. Therefore, financial assets and liabilities not carried at fair value, such as accounts payable, are still reported at their carrying values.

Fair value measurements at each reporting date were as follows:

September 28, 2014:

Assets and liabilities measured at fair value on a recurring basis were presented in the Company’s condensed consolidated balance sheet as of September 28, 2014.

Level 1 and 2 financial assets:

The fair values of money market funds were derived from quoted market prices as active markets for these instruments exist. The fair values of corporate notes and bonds, commercial paper, municipal notes and bonds and U.S. Agency Securities were derived from non-binding market consensus prices that are corroborated by observable market data.

Level 3 financial liabilities:

The following table provides a summary of changes in fair value of the Company’s contingent consideration categorized as Level 3 for the six months ended September 28, 2014:

	September 28, 2014
	(in thousands)
Beginning balance	$	—
Add: Contingent consideration in connection with acquisitions		16,034
Ending balance	$	16,034

Contingent consideration on acquired businesses (See Note 8) was measured at fair value using Level 3 inputs as defined in the fair value hierarchy. The following table presents certain information about the significant unobservable inputs used in the fair value measurement for the contingent consideration measured at fair value on a recurring basis using significant unobservable inputs:

Description	Valuation Techniques	Significant Unobservable Inputs
Liabilities: Contingent consideration	Present value of a Probability Weighted Earn-out model using an appropriate discount rate.	Estimate of meeting the milestones.

An increase in the estimate of probability of meeting the milestones could result in a significantly higher estimated fair value of the contingent consideration liability. Alternatively, a decrease in the estimate of probability of meeting the milestones could result in a significantly lower estimated fair value of contingent consideration liability.

The fair value of contingent consideration was derived from a probability weighted earn-out model of future contingent payments. The cash payments are expected to be made upon meeting the milestones (See Note 8). The valuation of the contingent consideration was based on a collaborative effort of the Company’s engineering and finance departments, and third party valuation experts. The estimate of meeting the milestones and discount rates will be reviewed quarterly and updated as and when necessary. Potential valuation adjustments will be made to adjust the contingent consideration payments. These adjustments will be recorded in the statements of operations.

There were no transfers of assets measured at fair value between Level 1 and Level 2 during the six months ended September 28, 2014.

Organization and Summary of Significant Accounting Policies

1. Organization and Summary of Significant Accounting Policies

Business

InvenSense, Inc. (“the Company”) was incorporated in California in June 2003 and reincorporated in Delaware in January 2004. The Company designs, develops, markets and sells Micro-Electro-Mechanical Systems (“MEMS”) sensors, such as accelerometers, gyroscopes and microphones for consumer electronics, and is dedicated to bringing the best-in-class size, performance and cost solutions to market. Targeting applications in smartphones and tablets, console and portable video gaming devices, digital still and video cameras, smart TVs (including digital set-top boxes, televisions and multi-media HDDs), navigation devices, toys, and health and fitness accessories, the Company delivers leading solutions based on its advanced multi-axis technology.

These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto for the fiscal year ended March 30, 2014 included in the Company’s Annual Report on Form 10-K filed on May 29, 2014 with the Securities and Exchange Commission (“SEC”). No material changes have been made to the Company’s significant accounting policies since the Company’s Annual Report on Form 10-K for the fiscal year ended March 30, 2014.

Certain Significant Business Risks and Uncertainties

The Company participates in the high-technology industry and believes that adverse changes in any of the following areas could have a material effect on the Company’s future financial position, results of operations, or cash flows: reliance on a limited number of primary customers to support the Company’s revenue generating activities; advances and trends in new technologies and industry standards; market acceptance of the Company’s products; development of sales channels; strategic relationships, including key component suppliers; litigation or claims against the Company based on intellectual property, patent, product, regulatory, or other factors; and the Company’s ability to attract and retain employees necessary to support its growth.

Basis of Consolidation

The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles, or GAAP, and include our accounts and the accounts of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The functional currency of each of the Company’s subsidiaries is the U.S. dollar. Foreign currency gains or losses are recorded as other income (expense), net, in the condensed consolidated statements of operations.

Fiscal Year

The Company’s fiscal year is a 52 or 53 week period ending on the Sunday closest to March 31. The Company’s most recent fiscal year (“Fiscal 2014”) ended on March 30, 2014 (“March 2014”). The second fiscal quarter in each of the two most recent fiscal years ended on September 28, 2014 (“three months ended September 28, 2014” or “September 2014”) and September 29, 2013 (“three months ended September 29, 2013” or “September 2013”), respectively, and each quarter period included 13 weeks.

Use of Estimates

The preparation of the Company’s Condensed Consolidated Financial Statements and related Notes in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and related Notes and the reported amounts of income and expenses during the reporting period. Significant estimates included in the Consolidated Financial Statements and related Notes include income taxes, inventory valuation, stock-based compensation, loss contingencies, warranty reserves, valuation of acquired assets and contingent consideration, and valuation of convertible senior notes, including the related convertible notes hedges and warrants. These estimates are based upon information available as of the date of the consolidated financial statements, and actual results could differ from those estimates.

Concentration of Credit Risk

At September 28, 2014, two customers accounted for 55% and 12% of accounts receivable. At March 30, 2014, three customers accounted for 28%, 19% and 19% of accounts receivable.

For the three months ended September 28, 2014, two customers accounted for 29% and 26% of net revenue. For the six months ended September 28, 2014, three customers accounted for 30%, 17% and 10% of net revenue. For the three months ended September 29, 2013, two customers accounted for 36% and 14% of net revenue. For the six months ended September 29, 2013, one customer accounted for 31% of net revenue.

Warranty

The Company’s warranty agreements are contract and component specific and can be for a period of up to three years after shipment for selected components. The accrual includes management’s judgment regarding anticipated rates of warranty claims and associated repair costs. The following table summarizes the activity related to product warranty liability during the six months ended September 28, 2014 and September 29, 2013:

	Six Months Ended
	September 28, 2014			September 29, 2013

Adjustments related to changes in estimate		(96	)		(203	)
Less: actual warranty costs		(15	)		(16	)
Ending balance	$	72		$	101

Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares outstanding during the period, which excludes dilutive unvested restricted stock.

Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares outstanding, including unvested restricted stock, certain warrants to purchase common stock and potential dilutive shares from the dilutive effect of outstanding stock options using the treasury stock method.

The following table presents the calculation of basic and diluted net income (loss) per share:

	Three Months Ended					Six Months Ended

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU No. 2014-09 provides guidance that companies will recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the payment to which a company expects to be entitled in exchange for those goods or services. The Company will be required to implement the new revenue recognition standard for the first quarter of fiscal year 2018. The Company is currently evaluating the impact on its consolidated financial statements.

Stockholders' Equity

6. Stockholders’ Equity

Stock Plans

In July 2011, the Company’s Board of Directors and its stockholders approved the establishment of the 2011 Stock Incentive Plan (the “2011 Plan”). The 2011 Plan provides for annual increases in the number of shares available for issuance there under on the first business day of each fiscal year, beginning with the Company’s fiscal year following the year of this offering, equal to four percent (4%) of the number of shares of the Company’s common stock outstanding as of such date, which resulted in an annual increase of 3.5 million shares for fiscal year 2015.

Under the Company’s 2004 Stock Incentive Plan and 2011 Stock Incentive Plan (the “Plans”), the Board of Directors may grant either incentive stock options, nonqualified stock options, or stock awards to eligible persons, including employees, nonemployees, members of the Board of Directors, consultants and other independent advisors who provide services to the Company.

Incentive stock options may only be granted to employees and at an exercise price of no less than 100% of fair value on the date of grant. Nonqualified stock options may be granted at an exercise price of no less than 100% of fair value on the date of grant. For owners of more than 10% of the Company’s common stock, options may only be granted for an exercise price of not less than 110% of fair value, and these options generally expire 10 years from the date of grant. Stock options may be exercisable immediately but are subject to repurchase. Stock options vest over the period determined by the Board of Directors, generally four years.

Stock option activities of the Company under the Plans are as follows (in thousands, except per share amounts):

	Options Available for Grant			Options Issued and Outstanding			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (In Years)		Aggregate Intrinsic Value
Outstanding — March 30, 2014		12,595			8,276		$	10.37		7.87	$	102,072

Valuation of Stock-Based Awards

The Company applies the provisions of ASC 718-10 “Compensation — Stock Compensation” which establishes the accounting for stock-based awards based on the fair value of the award measured at grant date. Accordingly, stock-based compensation cost is recognized in the condensed consolidated statements of operations as a component of both cost of revenues and operating expenses over the requisite service period. ASC 718-10 requires tax benefits in excess of compensation cost to be reported as a financing cash flow rather than as a reduction of taxes paid. The determination of the fair value of stock-based payment awards on the date of grant using the Black-Scholes option pricing model is affected by the volatilities of a peer group of companies based on industry, stage of life cycle, size and financial leverage, actual and projected employee stock option exercise behaviors, risk-free interest rate and expected dividends. Variables to be determined include expected volatility, estimated term and risk-free interest rate.

The aggregate intrinsic value of the stock options exercised during the three and six months ended September 28, 2014 was $11.2 million and $14.1 million respectively. The aggregate intrinsic value of the stock options exercised during the three and six months ended September 29, 2013 was $11.3 million and $22.8 million respectively. The aggregate intrinsic value was calculated as the difference between the exercise price of the stock options and the estimated fair market value of the underlying common stock at the date of exercise.

The number of options expected to vest takes into account an estimate of expected forfeitures. The remaining unamortized stock-based compensation expense, reduced for estimated forfeitures and related to non-vested options, was $18.3 million, and $20.7 million at September 28, 2014 and September 29, 2013, respectively, and will be amortized over a weighted-average remaining period of approximately 2.6 and 3.1 years, respectively. Total unrecognized expense will be adjusted for future changes in estimated forfeitures.

The Company used the following weighted-average assumptions in determining stock-based compensation expense for options granted in the three and six months ended September 28, 2014 and September 29, 2013.

	Three Months Ended						Six Months Ended
	September 28, 2014			September 29, 2013			September 28, 2014			September 29, 2013

Restricted Stock Units and Restricted Stock

Restricted stock unit and restricted stock activity of the Company under the Plans are as follows:

Restricted stock units and restricted stock activities	Shares			Weighted Average Grant Date Fair Value Per Share
	(in thousands, except per share amount)
Unvested at March 30, 2014		3,325		$	16.63
Granted		1,048			21.84
Released		(378	)		13.93
Forfeited		(99	)		16.64
Unvested at September 28, 2014		3,896		$	18.29

Restricted stock units and restricted stock granted to employees are generally subject to the employee’s continued service to the Company over that period. The fair value of restricted stock units and restricted stock is determined using the fair value of the Company’s common stock on the date of the grant. Compensation expense is generally recognized on a straight-line basis over the requisite service period of each grant adjusted for estimated forfeitures. At September 28, 2014, there was approximately $43.6 million of total unrecognized compensation cost related to restricted stock units and restricted stock, which the Company expects to recognize over a weighted-average period of 3.2 years. The weighted-average grant-date fair value per share of restricted stock units and restricted stock awarded in the six months ended September 28, 2014 and September 29, 2013 was $21.84 and $14.69, respectively.

Common Stock

As of September 28, 2014 and March 30, 2014, common stock reserved for future issuance was as follows:

2013 Employee Stock Purchase Plan

Under the 2013 Employee Stock Purchase Plan, effective September 13, 2013, (the “Purchase Plan”), eligible employees may apply accumulated payroll deductions, which may not exceed 10% of an employee’s compensation, to the purchase of shares of the Company’s common stock at periodic intervals. The purchase price of stock under the Purchase Plan is equal to 85% of the lower of (i) the fair market value of the Company’s common stock on the first day of each offering period, or (ii) the fair market value of the Company’s common stock on the purchase date (as defined in the Purchase Plan). Each offering period consists of one purchase period of approximately six months duration.

An aggregate of 400,000 shares of common stock were reserved for issuance to employees under the Purchase Plan. As of September 28, 2014, 61,000 shares had been purchased.

Stock-Based Compensation Expense

Total employee stock-based compensation costs for the Company’s stock plans for the three and six months ended September 28, 2014 and September 29, 2013 are as follows:

Convertible Senior Notes

Debt Disclosure [Abstract]

Convertible Senior Notes

5. Convertible Senior Notes

In November 2013, the Company issued $175.0 million aggregate principal amount of 1.75% Convertible Senior Notes due on November 1, 2018 (the “Notes”), in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933 (the “Securities Act”). The Notes offered have not been registered under the Securities Act, or applicable state securities laws or blue sky laws, and may not be offered or sold in the United States absent registration under the Securities Act and applicable state securities laws or available exemptions from the registration requirements.

The Notes are senior unsecured obligation of the Company and rank equally in right of payment with all of the Company’s existing and future senior unsecured indebtedness and are junior to any of the Company’s existing and future secured indebtedness. The Notes pay interest in cash semi-annually (May and November) at a rate of 1.75% per annum. Net proceeds received by the Company, after issuance costs, were approximately $169.3 million.

On or after August 1, 2018 until the maturity date, the Notes may be converted at the option of the holders. Holders may convert the Notes at their option prior to August 1, 2018 only under the following circumstances:

1) During any calendar quarter commencing after the calendar quarter ending on March 31, 2014 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

2) During the five business day period after any five consecutive trading day period in which the “trading price” per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; or

3) Upon the occurrence of specified corporate events, including if there is a fundamental change.

Upon conversion, the Company will pay cash up to the aggregate principal amount of the Notes to be converted and pay or deliver cash, shares of its own common stock or a combination of cash and shares of its own common stock, at the Company’s election, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the notes being converted.

The conversion rate is initially 45.683 shares per $1,000 principal amount of the Notes (equivalent to an initial conversion price of approximately $21.89 per share of common stock), subject to certain adjustments.

The Notes are not redeemable by the Company prior to the maturity date. At the event of default or fundamental change, the principal amount of the notes plus accrued and unpaid interest may become due immediately at the Note holders’ option.

The Company used and plans to use the net proceeds of approximately $169.3 million from the offering of the Notes (after the issuance costs) for general corporate purposes, including to replace cash used for business acquisitions (see Note 8), for the cost of the Note hedge transactions (see below) and for capital expenditures and working capital. However, the Company has not designated with certainty all of the particular uses for the net proceeds from the Notes.

The Company separately accounts for the liability and equity components of the Notes. The initial debt component of the Notes was valued at $135.7 million based on the contractual cash flows discounted at an appropriate comparable market non-convertible debt borrowing rate at the date of issuance of 7.3%, with the equity component representing the residual amount of the proceeds of $39.3 million which was recorded as a debt discount. The issuance costs were allocated pro-rata based on the relative initial carrying amounts of the debt and equity components, including the Note hedges and warrants transactions described below. As a result, $2.5 million of the issuance costs was allocated to the equity component of the Notes, $3.0 million of issuance costs paid to the initial purchaser was accounted for as a debt discount and $0.25 million of the issuance costs was classified as other non-current assets. The debt discount and the issuance costs allocated to the debt component are amortized as additional interest expense over the term of the Notes using the effective interest method. As of September 28, 2014 the remaining amortization period of the debt discount and the issuance costs is 4.1 years. The effective interest rate of the Notes is 7.84% per annum (1.75% coupon rate plus 6.09% of non-cash accretion expense).

Convertible Notes Hedges and Warrants

Concurrent with the issuance of the Notes on November 6 and 7, 2013, the Company purchased call options for its own common stock to hedge the Notes (the “Note Hedge”) and sold call options for its own common stock (the “Warrants”). The Note Hedges and Warrants transactions are structured to reduce the potential future economic dilution associated with the conversion of the Notes and are excluded from the computation of diluted earnings per share for each period presented, as the Company’s average stock price during each period is less than the conversion price.

The Note Hedges — On November 6 and 7, 2013, the Company purchased call options from a counterparty for an aggregate price of approximately $39.1 million, which gives the Company the right to buy from the counterparty up to approximately 8.0 million shares of the Company’s common stock at a price of $21.89 per share, subject to adjustments. The Note Hedge is exercisable upon conversion of the Note for a number of shares equal to the product of 0.045683 and amount of the converted Note. Upon exercise of the Note Hedge the Company will receive from the counterparty cash, shares of Company’s common stock, or a combination thereof, equal to the amount by which the market price per share of the Company’s common stock exceeds $21.89 during the applicable valuation period. By the Note Hedge terms the Company will receive cash and shares in a combination that offsets share dilution caused by conversion of the Note.

Warrants — On November 6 and 7, 2013, the Company sold call options to the same counterparty for approximately $25.6 million, which gives the counterparty the right to buy from the Company up to approximately 8.0 million shares of the Company’s common stock at an exercise price of $28.66 per share, subject to adjustments, on a series of days commencing on February 1, 2019 and ending May 13, 2019. Upon exercise of the Warrants, the Company has the option to deliver cash or shares of its common stock equal to the difference between the market price on the exercise date and the strike price of the warrants. Upon exercise of the Warrants, the Company will pay to the Initial Purchaser cash, shares of Company’s common stock, or a combination thereof (at the Company’s choice), equal to the amount by which the market price per share of the Company’s common stock exceeds $28.66 during the applicable valuation period.

The Note Hedges and Warrants above are classified in stockholders’ equity in the Company’s consolidated balance sheets.

Goodwill and Purchased Intangible Assets

9. Goodwill and Purchased Intangible Assets

Purchased intangible assets subject to amortization consist primarily of developed technology and customer relationships and are reported net of accumulated amortization. Developed technology and customer relationships are amortized on a straight line basis over the estimated useful life of the assets. In-process research and development is assessed for impairment until the development is completed and products are available for sale. The Company expects to complete the in-process research and development projects at various dates during fiscal year 2015 at which time amortization will commence. During the three months ended September 28, 2014, the Company recorded $0.8 million of impairment on in-process research and development on one of the ADI acquisition projects.

The following table summarizes the activity related to the carrying value of goodwill (in thousands):

Income Taxes

7. Income Taxes

In the three and six months ended September 28, 2014, the Company recorded an income tax provision of $0.6 million and $0.9 million respectively. In the three and six months ended September 30, 2013, the Company recorded an income tax provision of $1.9 million and $3.8 million respectively. The Company’s estimated 2015 effective tax rate differs from the U.S. statutory rate primarily due to profits earned in jurisdictions where the tax rate is lower than the U.S. tax rate partially offset by the unfavorable effects of non-deductible stock-based compensation expense.

The Company files U.S. federal income tax returns as well as income tax returns in California, Massachusetts and various foreign jurisdictions. The Company has not provided for U.S. federal income and foreign withholding taxes on undistributed earnings from non-U.S. operations as of September 28, 2014 because such earnings are to be reinvested indefinitely.

The Company has recorded $10.5 million of uncertain tax positions within “Other long-term liabilities” on the condensed consolidated balance sheet as at September 28, 2014. The Company does not expect any significant increases or decreases to its unrecognized tax benefits within the next twelve months. While management believes that the Company has adequately provided for all tax positions, amounts asserted by tax authorities could be greater or less than the recorded position. Accordingly, the Company’s provisions on federal, state and foreign tax-related matters to be recorded in the future may change as revised estimates are made or the underlying matters are settled or otherwise resolved.

The Company’s tax year from 2003 and onwards could be subject to examinations by tax authorities in one or more tax jurisdictions. The Internal Revenue Service (the “IRS”) is currently examining the fiscal years 2011 through 2013. In addition, the Company is subject to audits by state, local, and foreign tax authorities. Management believes that adequate provisions have been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs.

Movea S.A

On July 22, 2014, the Company acquired 100% equity interest of Movea, a company formed under the laws of France, and a leading provider of software for ultra-low power location, activity tracking and context sensing. The acquisition of Movea further scales the Company’s leadership in motion software.

The Company paid $60.9 million in cash as consideration for the acquisition and could pay an additional $13.0 million in cash contingent upon the achievement of certain milestones within one year of the acquisition.

In addition, the Company, under its 2011 Stock Incentive Plan granted restricted stock units (RSU), with a fair value of $6.6 million, to certain Movea employees. The RSUs will vest over a 5 year requisite service period.

The table below is a summary of the preliminary purchase price allocation of the fair value of assets acquired and liabilities assumed in connection with the acquisition of Movea (in thousands):

Cash consideration	$	60,900
Contingent consideration		8,400
	$	69,300
Preliminary allocation of purchase price:
Current assets	$	3,082
Fixed assets		209
Other non-current assets		592
Developed technology		7,200
Goodwill		68,330
Current liabilities		(5,016	)
Long-term liabilities		(5,097	)
Total preliminary purchase price	$	69,300

The purchase price includes contingent considerations of (i) $8.0 million payable in cash to the former Movea shareholders upon a design win with a major smartphone manufacturer within one year of closing date, and (ii) $5.0 million payable in cash to the former Movea shareholders upon a specific product development milestone by December 2014. The fair value of the contingent consideration of $8.4 million was derived from a probability weighted earn-out model of future contingent payments.

The purchase price exceeded the fair value of the net tangible and identifiable intangible assets acquired and, as a result, the Company recorded goodwill in connection with this transaction. The acquisition will provide assembled workforce and synergy with other of the Company’s offerings. These factors primarily contributed to a purchase price that resulted in goodwill.

The following table presents certain information on acquired identifiable intangible assets related to the Movea acquisition:

	Estimated Fair Value (in thousands)		Estimated Useful Life (in years)
Developed technology	$	7,200		5

The fair value of developed technology was determined using a cost approach, which includes an estimate of time and expenses required to recreate the intangible asset. The fair value of developed technology was capitalized as of the acquisition date and will be amortized using a straight-line method to cost of revenue over the estimated useful life of 5 years.

Trusted Positioning, Inc.

On August 29, 2014, the Company completed the acquisition of Trusted Positioning, Inc., (“TPI”), a Canadian corporation, which is an indoor/outdoor positioning software company with the vision to provide ‘Positioning Everywhere’. The acquisition of TPI, particularly its advanced location tracking software, strengthens the Company’s position as a provider of intelligent sensor System on Chips (SoC) for the fast growing mobile market.

The Company’s acquisition of TPI was completed through a step acquisition. In fiscal 2014, the Company made investments totaling $0.3 million to own approximately 4.57% of TPI’s outstanding common stock. On August 29, 2014, the Company purchased the remaining outstanding common stock of TPI for a total consideration of $26.1 million. The total purchase price, as presented in the table below, consists of (i) cash of $11.5 million (ii) issuance of 236,000 shares of the Company’s common stock with a fair value of $5.7 million (iii) contingent considerations with a combined fair value of $7.6 million payable upon TPI’s achievement of certain product development milestones, and (iv) initial investments with a fair value of $1.2 million.

In addition, the Company, under its 2011 Stock Incentive Plan, granted equity awards (restricted stock units and stock options), to certain TPI employees with an aggregate fair value of $5.0 million. The equity awards will vest over a 5 year requisite service period.

The table below is a summary of the preliminary purchase price allocation for the 100% equity interest of the fair value of assets acquired and liabilities assumed in connection with the acquisition of TPI (in thousands):

Cash consideration	$	11,499
Issuance of common stock		5,703
Contingent consideration		7,634
Fair value of previously held 4.57% equity interest		1,215
	$	26,051
Preliminary allocation of purchase price:
Current assets	$	512
Fixed assets		50
Other non-current assets		546
Developed technology		8,600
Goodwill		19,893
Current liabilities		(1,247	)
Long-term liabilities		(2,303	)
Total preliminary purchase price	$	26,051

The purchase price includes contingent consideration comprised of (i) $5 million payable upon a design win within one year of acquisition, (ii) $3 million payable upon achieving a development milestone by December 2014, (iii) $2 million payable upon successful development of cloud application within two years of acquisition and (iv) $2 million upon first deployment of cloud application which is expected within one year of successful development of cloud application. The contingent considerations, which was derived from a probability weighted earn-out model of future contingent payments, have a combined fair value of $7.6 million, of which $4.9 million was recorded in accrued liabilities and $2.7 million was recorded in other long-term liabilities.

The following table presents certain information on acquired identifiable intangible assets related to the TPI acquisition:

	Estimated Fair Value (in thousands)		Estimated Useful Life (in years)
Developed technology	$	8,600	5

The fair value of developed technology was determined using a cost approach, which includes an estimate of time and expenses required to recreate the intangible asset. The fair value of developed technology was capitalized as of the acquisition date and will be amortized using a straight-line method to cost of revenue over the estimated useful life of 5 years.

In connection with the acquisition of TPI, the Company recorded a non-cash gain of approximately $0.9 million resulting from the difference between carrying value of its initial investments in TPI of $0.3 million and fair value of such investments of $1.2 million, as of the acquisition date. This non-cash gain is recorded in “Other income, net” on the Condensed Consolidated Statement of Operations.

MEMS Microphone Business of Analog Devices, Inc.

In the third quarter of fiscal 2014, the Company acquired certain assets relating to Analog Devices, Inc. (“ADI”) MEMS microphone business for a purchase price of $100 million in cash, of which the Company is entitled to certain contingent future expense reimbursements of approximately $2.2 million. The Company also agreed to a contingent cash payment of up to $70.0 million payable upon the achievement of certain revenue performance targets within one year of the transaction close date. Due to a low probability of achieving the revenue targets, the fair value of the contingent consideration is estimated to be zero in the purchase price allocation described below. ADI licensed certain technology related to the MEMS microphone business to the Company on a royalty-free, worldwide basis, and provides certain transition services to the Company following the closing.

The strategic rationale for the acquisition was to accelerate the Company’s audio roadmap and complement its current MEMS System on Chip product offerings at existing mobile, gaming and wearable device customers, while gaining entry into new markets. The acquisition expands the Company’s patent portfolio and existing tier one customer base, which includes major OEM brands worldwide.

The allocation of the purchase price of the assets acquired and liabilities assumed based on their fair values was as follows:

	Total Amount
	(in thousands)
Inventories	$	5,107
Property and equipment, net		4,339
Intangible assets:
Developed technology		28,520
In-Process Research & Development		7,330
Customer Relationships		1,560
Goodwill		50,952
Total assets acquired	$	97,808
Total purchase price (net of $2.2 million of contingent expense reimbursements)		97,808

The fair value of intangible assets of $37.4 million has been allocated to the following three asset categories: 1) developed technology, 2) in-process research & development and 3) customer relationships. Developed technology and customer relationships are amortized on a straight line basis over the estimated useful life of the assets.

The table below presents certain information on acquired identifiable intangible assets related to the ADI acquisition:

	Estimated Fair Value (in thousands)		Estimated Useful Life (in years)
Developed technology	$	28,520	6
Customer relationships	$	1,560	7

The amounts of revenue and earnings of the Microphone Product Line since the acquisition date included in the consolidated statements of operations for the current reporting periods have not been presented because the impact was not material to the Company’s consolidated results of operations.

No material changes have been made to the Company’s significant accounting policies since the Company’s Annual Report on Form 10-K for the fiscal year ended March 30, 2014.

Certain Significant Business Risks and Uncertainties

Certain Significant Business Risks and Uncertainties

The Company participates in the high-technology industry and believes that adverse changes in any of the following areas could have a material effect on the Company’s future financial position, results of operations, or cash flows: reliance on a limited number of primary customers to support the Company’s revenue generating activities; advances and trends in new technologies and industry standards; market acceptance of the Company’s products; development of sales channels; strategic relationships, including key component suppliers; litigation or claims against the Company based on intellectual property, patent, product, regulatory, or other factors; and the Company’s ability to attract and retain employees necessary to support its growth.

Basis of Consolidation

Basis of Consolidation

The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles, or GAAP, and include our accounts and the accounts of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The functional currency of each of the Company’s subsidiaries is the U.S. dollar. Foreign currency gains or losses are recorded as other income (expense), net, in the condensed consolidated statements of operations.

Fiscal Year

Fiscal Year

The Company’s fiscal year is a 52 or 53 week period ending on the Sunday closest to March 31. The Company’s most recent fiscal year (“Fiscal 2014”) ended on March 30, 2014 (“March 2014”). The second fiscal quarter in each of the two most recent fiscal years ended on September 28, 2014 (“three months ended September 28, 2014” or “September 2014”) and September 29, 2013 (“three months ended September 29, 2013” or “September 2013”), respectively, and each quarter period included 13 weeks.

Use of Estimates

Use of Estimates

The preparation of the Company’s Condensed Consolidated Financial Statements and related Notes in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and related Notes and the reported amounts of income and expenses during the reporting period. Significant estimates included in the Consolidated Financial Statements and related Notes include income taxes, inventory valuation, stock-based compensation, loss contingencies, warranty reserves, valuation of acquired assets and contingent consideration, and valuation of convertible senior notes, including the related convertible notes hedges and warrants. These estimates are based upon information available as of the date of the consolidated financial statements, and actual results could differ from those estimates.

Concentration of Credit Risk

Concentration of Credit Risk

At September 28, 2014, two customers accounted for 55% and 12% of accounts receivable. At March 30, 2014, three customers accounted for 28%, 19% and 19% of accounts receivable.

For the three months ended September 28, 2014, two customers accounted for 29% and 26% of net revenue. For the six months ended September 28, 2014, three customers accounted for 30%, 17% and 10% of net revenue. For the three months ended September 29, 2013, two customers accounted for 36% and 14% of net revenue. For the six months ended September 29, 2013, one customer accounted for 31% of net revenue.

Warranty

Net Income (Loss) Per Share

Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares outstanding during the period, which excludes dilutive unvested restricted stock.

Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares outstanding, including unvested restricted stock, certain warrants to purchase common stock and potential dilutive shares from the dilutive effect of outstanding stock options using the treasury stock method.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU No. 2014-09 provides guidance that companies will recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the payment to which a company expects to be entitled in exchange for those goods or services. The Company will be required to implement the new revenue recognition standard for the first quarter of fiscal year 2018. The Company is currently evaluating the impact on its consolidated financial statements.

Fair Value Measurements

The Company applies the provisions of ASC 820-10, “Fair Value Measurements”. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. ASC 820-10 requires disclosure that establishes a framework for measuring fair value and expands disclosure about fair value measurements. The standard describes a fair value hierarchy based on three levels of inputs that may be used to measure fair value. The inputs for the first two levels are considered observable and the last is unobservable and include the following:

Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2 — Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; or

Level 3 — Unobservable inputs in which there is little or no market data, and as a result, prices or valuation techniques are employed that require inputs that are significant to the fair value measurement.
