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 sensor systems on a chip, including accelerometers, gyroscopes and microphones for the mobile, wearable, smart home, gaming, industrial, and automotive market segments.

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 29, 2015 included in the Company’s Annual Report on Form 10-K filed on May 28, 2015 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 29, 2015.

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 (“GAAP”), and include the Company’s accounts and the accounts of its 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 2015”) ended on March 29, 2015 (“March 2015”). The third fiscal quarter in each of the two most recent fiscal years ended on December 27, 2015 (“three months ended December 27, 2015”) and December 28, 2014 (“three months ended December 28, 2014”), respectively, and each quarter period included 13 weeks. Fiscal year 2016 is a 53-week fiscal year ending April 3, 2016 (“Fiscal 2016”). The extra week is included in our fourth fiscal quarter ended April 3, 2016.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP and applicable rules and regulations of the SEC regarding interim financial reporting. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations.

The condensed consolidated balance sheet as of March 29, 2015, included herein was derived from the audited financial statements as of that date, but does not include all disclosures required by GAAP. The unaudited interim condensed consolidated financial statements, in the opinion of management, reflect all normal recurring adjustments necessary to present fairly the Company’s financial position, results of operations, comprehensive income (loss) and cash flows for the interim periods. The results of operations for the period ended December 27, 2015 is not necessarily indicative of the results to be expected for the fiscal year ending April 3, 2016 or for any future year or interim period.

Use of Estimates

The preparation of the Company’s Condensed Consolidated Financial Statements and notes thereto in conformity with 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 notes thereto and the reported amounts of income and expenses during the reporting period. Significant estimates included in the Consolidated Financial Statements and notes thereto include income taxes, inventory valuation, stock-based compensation, goodwill, 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.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. In accordance with Accounting Standard Codification 350, the Company reviews goodwill for impairment at the reporting unit level on an annual basis or whenever events or changes in circumstances indicate the carrying value may not be recoverable. As the Company uses the market approach to assess impairment, its common stock price is an important component of the fair value calculation. The Company has determined that it has a single reporting unit for purposes of performing its goodwill impairment test. The Company performed its annual impairment test during the quarter ended December 27, 2015 and determined that its goodwill was not impaired.

Concentration of Credit Risk

The majority of the Company’s products are shipped through its distributors or contract manufacturers (collectively “intermediaries”), who are the legal counter-parties to our sales. When the Company references customers, sales and revenue in this report, the Company is referring to the manufacturers of consumer electronics devices who are the end customers for our products. However, any disclosure about the composition of the Company’s accounts receivable refers to the intermediaries. Some of the Company’s intermediaries may serve more than one of the Company’s customers. As a result, attempting to compare or correlate disclosures about our accounts receivable composition as of a particular date with the disclosures regarding revenues generated by our customers for the period ending on the same date can be difficult or misleading.

A distributor accounted for 69% of accounts receivable at December 27, 2015. A distributor and a customer accounted for 77% and 12% of accounts receivable, respectively, at December 28, 2014.

For the three months ended December 27, 2015, one customer accounted for 47% of net revenue and another customer accounted for 13% of net revenue. For the nine months ended December 27, 2015, one customer accounted for 40% of net revenue and another customer accounted for 18% of net revenue. For the three months ended December 28, 2014, one customer accounted for 45% of net revenue and another customer accounted for 24% of net revenue. For the nine months ended December 28, 2014, one customer accounted for 29% of net revenue and another customer accounted for 28% of net revenue.

Warranty

The Company offers one year standard warranty on its products. In selective cases, the warranty period could be extended to multiple years. The Company’s accrual for anticipated warranty costs has increased primarily due to an increase in unit sales volume and a commensurate increase in the volume of product returned under the warranty agreements. The accrual also 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 nine months ended December 27, 2015 and December 28, 2014:

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. In periods in which the Company has reported a net loss, the common stock equivalents are excluded from the calculation of diluted net loss per share of common stock as their effect is antidilutive under the treasury stock method.

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

Recent Accounting Pronouncements

On November 20, 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-17. The new guidance requires that all deferred tax assets and liabilities, along with any related valuation allowance for each tax-paying jurisdiction within each tax-paying component, be classified as noncurrent on the balance sheet. The new guidance will be effective for public business entities in fiscal years beginning after December 15, 2016, including interim periods within those years. Early adoption is permitted for all entities as of the beginning of an interim or annual reporting period. The Company does not expect this guidance to have significant impact on its consolidated financial statements.

2. Cash Equivalents and Available-for-Sale Investments

At December 27, 2015, cash and cash equivalents totaled $43.9 million, of which $33.0 million was cash and $10.9 million was cash equivalents invested in money market funds. At December 27, 2015, $26.4 million of the 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 December 27, 2015, the Company had short-term available-for-sale investments of $253.3 million which are held in the US entity.

At March 29, 2015, cash and cash equivalents totaled $85.6 million, of which $61.6 million was cash and $24.0 million was cash equivalents. At March 29, 2015, $47.7 million of the cash and cash equivalents were held by our foreign subsidiaries. Additionally, as of March 29, 2015, the Company had short-term available-for-sale investments of $129.9 million which are held in the US entity.

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 the Company’s 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 nine months ended December 27, 2015:

	Nine Months Ended
	December 27, 2015			December 28, 2014
	(in thousands)
Beginning balance	$	9,124		$	—
Add: Contingent consideration in connection with acquisitions		—			16,034
Payments made on contingent liabilities		(1,908	)		—
Change in fair value and other		(5,307	)		875
Ending balance	$	1,909		$	16,909

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 achieving 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 initial 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.

During the nine months ended December 27, 2015, the fair value of contingent consideration declined by $5.3 million. The decline in fair value was the result of a reduction in the probability of a design win milestone associated with the Movea, S.A., (“Movea”) acquisition from 50% to 0% and a reduction in the probability of a design win associated with the Trusted Positioning, Inc. (“TPI”) acquisition from 50% to 0%. The decline in fair value of the design win milestones for Movea and TPI was $4.0 million and $2.4 million, respectively, which were recorded as a credit to research and development expense. The earn-out payments for the Movea and TPI’s design win milestones were not made as these mile stones were not met and expired during the nine months ended December 27, 2015. Offsetting this amount is an increase in the fair value of two TPI cloud application milestones as a result of an increase in the estimated probability of achievement of those milestones. The increase in the fair value of the cloud application milestones was $1.1 million which was recorded as a debit to research and development expense during the nine months ended December 27, 2015. A design milestone for TPI was achieved and the payment of $1.9 million was made during the three and nine months ended December 27, 2015.

4. Commitments and Contingencies

Operating Lease Obligations

The Company has non-cancelable operating leases for its facilities through fiscal year 2022.

Future minimum lease payments, net of future minimum lease income, under operating leases as of December 27, 2015 are as follows:

	Amount
Fiscal Years Ending:	(in thousands)
2016 (remainder)	$	1,206
2017		5,157
2018		6,340
2019		6,529
2020		5,184
Beyond		1,810
Total	$	26,226

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, net of the rent income from subleases of $0.4 million and $1.1 million, was approximately $1.1 million and $3.7 million for the three and nine months ended December 27, 2015, respectively. The Company’s rental expense under operating leases was approximately $1.3 million and $3.6 million for the three and nine months ended December 28, 2014, respectively.

Purchase Commitments

The Company has non-cancelable purchase commitments with its foundry vendors. Future minimum payments of $44.0 million under the purchase commitments as of December 27, 2015 are due in less than twelve months.

Legal Proceedings and Contingencies

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 litigation related to intellectual property and employment issues.

In January and March of 2015, purported shareholders filed five substantially similar class action complaints in the U.S. District Court, Northern District of California against the Company and two of the Company’s current and former executives (“Class Action Defendants”) (Jim McMillan v. InvenSense, Inc., et al. Case No. 3:15-cv-00084-JD, filed January 7, 2015; William Lendales v. InvenSense, Inc. et al., Case No. 3:15-cv-00142-VC, filed on January 12, 2015; Plumber & Steamfitters Local 21 Pension Fund v. InvenSense, Inc., et al., Case No. 5:15-cv-00249-BLF, filed on January 16, 2015; William B. Davis vs. InvenSense, Inc., et al., Case No. 5:15-cv-00425-RMW, filed on January 29, 2015; and Saratoga Advantage Trust Technology & Communications Portfolio v. InvenSense et al., Case No. 3:15-cv-01134, filed on March 11, 2015). On April 23, 2015, those cases were consolidated into a single proceeding which is currently pending in the U.S. District Court, Northern District of California and captioned In re InvenSense, Inc. Securities Litigation, Case No. 3:15-cv-00084-JD (the “Securities Case”), and the Vossen Group was designated as lead plaintiff. On May 26, 2015, the lead plaintiffs filed a consolidated amended class action complaint, which alleges that the defendants violated the federal securities laws by making materially false and misleading statements regarding our business results between July 29, 2014 and October 28, 2014, and seeks unspecified damages along with plaintiff’s costs and expenses, including attorneys’ fees. On June 25, 2015, the Class Action Defendants filed a motion seeking dismissal of the case and a hearing on that motion was held on October 7, 2015. The parties are awaiting the court’s decision.

In addition, in January and March of 2015, other purported shareholders filed three substantially similar shareholder derivative complaints against two of our current and former officers and several of our current directors, twice in the U.S. District Court, Northern District of California and once in Santa Clara Superior Court (George E Rollins v. Behrooz Abdi et al., Case No. 5:15-cv-00184-PSG, filed on January 13, 2015; Linda Karr v. Behrooz Abdi et al., Case No. 5:15-cv-00200-NC, filed on January 14, 2015; and Robert Bilbrey v. Behrooz Abdi et al., Case No. 1-15-CV-278742 was filed on March 20, 2015) (collectively, the “Derivative Cases”). In the Derivative Cases complaints, the plaintiffs make allegations similar to those presented in the Securities Case, but the plaintiffs asserts various state law causes of action, including claims of breach of fiduciary duty and unjust enrichment. The Company has undertaken an evaluation of these complaints. Plaintiffs in the Derivative Cases have agreed to an indefinite stay pending developments in the Securities Case. In light of the unresolved legal issues, while a loss is reasonably possible, the amount of any potential loss cannot be estimated. At this stage, the Company is unable to predict the outcome of this matter and, accordingly, cannot estimate the potential financial impact on the Company’s business, operating results, cash flows or financial position.

The semiconductor and MEMS industries are characterized by companies that hold large numbers of patents and other intellectual property rights and that vigorously pursue, protect and enforce intellectual property rights.

Robert Bosch GmbH (“Bosch”), one of the Company’s competitors, and the Company have each previously made generalized assertions of potential patent infringement by the other. On October 28, 2015, the Company and Bosch resolved all assertions of potential infringement between them and entered into a multi-year, worldwide patent cross license agreement for MEMS and sensor technologies, excluding patents covering InvenSense’s CMOS-MEMS eutectic bonding production process and Bosch’s two-layer porous silicon production process, and an upfront payment of $11.5 million to Bosch. The other terms of the settlement and the patent cross license agreement remain confidential and are not expected to have a material impact on our future results. Based on the status of the negotiations, the Company recognized a pre-tax charge of $11.7 million during the quarter ended June 28, 2015; there were no significant changes to the final terms which required any additional charge for prior periods to be recorded in the quarter ended December 27, 2015. In the future, other third parties may assert against the Company and its customers and distributors, their patent and other intellectual property rights to technologies that are important to our business.

The Company is not aware of any other pending legal matters or claims, individually or in the aggregate, that are expected to have a material adverse impact on its consolidated financial position, results of operations, or cash flows. However, the Company’s analysis of whether a claim may proceed to litigation cannot be predicted with certainty, nor can the results of litigation be predicted with certainty. Nevertheless, defending any of these actions, regardless of the outcome, may be costly, time consuming, distract management personnel, and have a negative effect on our business. An adverse outcome in any of these actions, including a judgment or settlement, may cause a material adverse effect on our future business, operating results, and/or financial condition.

The Company indemnifies certain customers, distributors, suppliers and subcontractors for attorney fees and damages and costs awarded against such parties in certain circumstances in which the Company’s products are alleged to infringe third-party intellectual property rights, including patents, registered trademarks or copyrights. Indemnification costs are charged to operations as incurred.

The Company’s Third Amended and Restated Bylaws require the Company to indemnify its directors and officers and employees to the fullest extent permitted by the Delaware General Corporation Law (DGCL). In addition, the Company’s current directors, including the Company’s chief executive officer and certain executive officers, have entered into separate indemnification agreements with the Company. The Company’s Second Amended and Restated Certificate of Incorporation, as amended, limits the liability of directors to the Company or its stockholders to the fullest extent permitted by the DGCL. The obligation to indemnify generally means that the Company is required to pay or reimburse the individuals’ reasonable legal expenses and possibly damages and other liabilities incurred in connection with these matters.

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 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 obligations 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 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 of $21.89 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.

18

INVENSENSE, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

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 an 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 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 were allocated to the equity component of the Notes, $3.0 million of issuance costs paid to the initial purchaser were accounted for as a debt discount and $0.25 million of the issuance costs were classified as other non-current assets. Debt issuance costs were reclassified and presented in the balance sheet as a direct deduction from the carrying value of the debt liability, consistent with the presentation of a debt discount in the first quarter of the Company’s fiscal year 2016 pertaining to the requirement of ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs. 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 December 27, 2015, the remaining amortization period of the debt discount and the issuance costs is 2.8 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 Notes 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 the 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.

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 3.6 million shares for fiscal year 2016.

Under the 2011 Plan, 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 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 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 2011 Plan and 2004 Stock Incentive Plan are as follows (in thousands, except per share amounts):

	Options Issued and Outstanding			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (In Years)		Aggregate Intrinsic Value
Balance — March 29, 2015		8,307		$	12.99		7.60	$	29,817
Options granted		1,692			14.50
Exercised options		(397	)		6.58
Cancelled options		(522	)		13.87

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 consolidated statements of income 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. The Company used historical experience to estimate expected term. The expected volatility was based on the historical stock volatilities of the Company’s historical data with that of a peer group of publicly listed companies over a period equal to the expected terms. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term. The Company does not anticipate paying any cash dividends in the foreseeable future and, therefore, uses an expected dividend yield of zero.

The aggregate intrinsic value of the stock options exercised during the three and nine months ended December 27, 2015 was $0.2 million and $2.8 million, respectively. The aggregate intrinsic value of the stock options exercised during the three and nine months ended December 28, 2014 was $2.3 million and $16.5 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 $17.9 million at December 27, 2015, and will be amortized over a weighted-average remaining period of approximately 2.4 years. 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 nine months ended December 27, 2015 and December 28, 2014.

	Three Months Ended						Nine Months Ended
	December 27,			December 28,			December 27,			December 28,
	2015			2014			2015			2014
Expected term (in years)		5.2			5.0			5.1			4.5
Volatility		44.8	%		45.9	%		45.1	%		42.1	%
Risk-free interest rate		1.7	%		1.6	%		1.5	%		1.5	%
Dividend rate		0	%		0	%		0	%		0	%

The weighted-average grant date fair value of the Company’s stock options granted in the three and nine month ended December 27, 2015 was $4.35 and $5.97 per share, respectively. The weighted-average grant date fair value of the stock options granted in the three and nine months ended December 28, 2014 was $6.65 and $7.28 per share, respectively.

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 29, 2015		4,030		$	17.75
Granted		1,559			13.12
Released		(807	)		17.00
Forfeited		(550	)		17.83
Unvested at December 27, 2015		4,232		$	16.18

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 December 27, 2015, there was $43.6 million of total unrecognized compensation cost related to restricted stock units and restricted stock, which the Company expects to recognize over a period of 2.7 years. The weighted-average grant-date fair value per share of restricted stock units and restricted stock awarded in the three and nine months ended December 27, 2015 was $10.44 and $13.12 per share, respectively. The weighted-average grant-date fair value per share of restricted stock units and restricted stock awarded in the three and nine months ended December 28, 2014 was $16.25 and $21.08 per share, respectively.

2013 Employee Stock Purchase Plan

Under the 2013 Employee Stock Purchase Plan, effective September 13, 2013, (the “ESPP”), 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 ESPP 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 ESPP). Each offering period consists of one purchase period of approximately nine months duration.

At the 2015 annual meeting of stockholders, stockholders of the Company approved an amendment to the current ESPP to increase the number of shares of common stock reserved for future issuance by 1,000,000 shares which brought the total of common stock reserved for issuance to employees to an aggregate of 1,400,000 shares. As of December 27, 2015, 400,000 shares had been purchased.

During the three and nine months ended December 27, 2015, compensation expense recognized in connection with the Purchase Plan was $0.1 million and $0.6 million, respectively. During the three and nine months ended December 28, 2014, compensation expense recognized in connection with the Purchase Plan was $0.3 million and $0.7 million, respectively.

Common Stock

As of December 27, 2015 and March 29, 2015, common stock reserved for future issuance was as follows:

7. Income Taxes

In the three and nine months ended December 27, 2015, the Company recorded an income tax provision (benefit) of $5.09 million and $3.36 million, respectively In the three and nine months ended December 28, 2014, the Company recorded an income tax provision (benefit) of ($2.7) million and ($1.9) million respectively. The Company’s estimated 2016 effective tax rate differs from the U.S. statutory rate primarily due to foreign tax differentials, a current year loss in the U.S., and was negatively affected by an increase in non-deductible stock option expense, and other deductible federal tax attributes.

Over 90% of our revenues are derived from sales to customers located outside the U.S. A significant percentage of our pre-tax income in the three months ended December 27, 2015 and December 28, 2014 was generated internationally, primarily from our Cayman Island subsidiary, which is currently a zero tax jurisdiction. Since 2011, our Cayman Island subsidiary has procured the rights to manufacture and sell our products in non-US locations via an intercompany technology license arrangement with its U.S. parent company. In addition, the Company has not provided for U.S. federal income and foreign withholding taxes on undistributed earnings from its non-U.S. subsidiaries, as it is the practice and intention of the Company to reinvest the earnings of its non-U.S. subsidiaries in those operations. Our effective tax rate is highly dependent upon the geographic distribution of our worldwide earnings or losses, and the tax regulations in each geographic region. We expect that a large percentage of our consolidated pre-tax income will continue to be derived from, and reinvested in, our overseas operations. We anticipate that this pre-tax income will continue to be subject to foreign tax at significantly lower tax rates when compared to the United States federal statutory tax rate.

The Company had deferred tax assets related to Research and Development Credits and other tax attributes including accrued expenses and stock based compensation that can be used to offset taxable income in future periods and reduce our income taxes payable in those future periods. Realization of our deferred tax assets is dependent upon future federal, state and foreign taxable income. Many of those credit carryforwards will expire if they are not used within certain time periods. As of December 27, 2015, management determined that there is sufficient positive evidence to conclude that it is more likely than not that we will have sufficient taxable income in the future that will allow us to realize these deferred tax assets (“DTAs”). However, it is possible that some or all of these credits could ultimately expire unused, especially if our U.S. entity does not make a taxable profit, which has been limited mainly due to stock option deductions since the company went public. Therefore, unless we are able to generate sufficient taxable income from our U.S. operations, a substantial valuation allowance to reduce our U.S. DTAs may be required, which would materially increase our expenses in the period the allowance is recognized and materially adversely affect our results of operations and statement of financial condition. Our judgments regarding future profitability may change due to future market conditions, changes in U.S. or international tax laws and other factors. These changes, if any, may require possible material adjustments to these deferred tax assets, resulting in a reduction in net income or an increase in net loss in the period when such determinations are made.

The Company has not provided for U.S. federal income and foreign withholding taxes on undistributed earnings from non-U.S. operations as of December 27, 2015.

The Company has recorded $14.2 million of uncertain tax positions within “Other long-term liabilities” on the condensed consolidated balance sheet as at December 27, 2015. 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 is in the process of an Internal Revenue Service (“IRS”) examination for tax years 2011, 2012, 2013 and 2014. The Company may be subject to examination by California for tax years 2010 and forward. Generally, the Company is subject to routine examination for tax years 2008 and forward in various foreign tax jurisdictions in which it operates.

8. Acquisition

The Company completed two acquisitions in fiscal 2015. The acquisitions have been accounted for using the acquisition method of accounting in accordance with ASC 805—Business Combinations. Under the acquisition method of accounting, the total purchase consideration of the acquisition is allocated to the tangible assets and identifiable intangible assets and liabilities assumed based on their relative fair values. The excess of the purchase consideration over the net tangible and identifiable intangible assets is recorded as goodwill, and was derived from expected benefits from future technology development, synergies and the knowledgeable and experienced workforce who joined the Company after the acquisition.

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 with the potential to pay an additional $13.0 million in cash contingent upon the achievement of certain milestones within one year of the acquisition.

The table below is a summary of the 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
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 included $2.6 million of long-term debt which was included in the long-term liabilities. The debt was measured at fair value using the effective interest rate method and considered as Level 3 inputs as defined in the fair value hierarchy, which approximates carrying value as of December 27, 2015.

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 before December 29, 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 and recorded in accrued liabilities. The product development milestone of $5.0 million was achieved and the payment was made in fiscal 2015. The difference between the contractual amount of $5.0 million and the fair value of this contingent consideration was recorded in the research and development expense for the year ended March 29, 2015. During the nine months ended December 27, 2015, the fair value of contingent consideration for Movea declined by $4.0 million. The decline in fair value was the result of a reduction in the probability of a design win milestone associated with the Movea acquisition from 50% to 0%. The decline in fair value of the design win milestones for Movea was recorded as a credit to research and development expense.

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 five 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 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 $25.9 million. The total purchase price, as presented in the table below, consists of (i) cash of $11.4 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.

The table below is a summary of the 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	$	11,379
Issuance of common stock		5,703
Contingent consideration		7,634
Fair value of previously held 4.57% equity interest		1,215
	$	25,931
Allocation of purchase price:
Current assets	$	392
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	$	25,931

The purchase price includes contingent consideration comprised of (i) $5.0 million payable upon a design win within one year of acquisition, (ii) $3.0 million payable upon achieving a development milestone before December 29, 2014, (iii) $2.0 million payable upon successful development of cloud application within two years of acquisition and (iv) $2.0 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 development milestone of $3 million was achieved and the payment was made in fiscal 2015. The difference between the contractual amount of $3.0 million and the fair value of this contingent consideration was recorded in the research and development expense for the year ended March 29, 2015.

During the nine months ended December 27, 2015, the fair value of contingent consideration for TPI declined by $1.3 million. The decline in fair value was the result of a reduction in the probability of a design win associated with the TPI acquisition from 50% to 0%. The decline in fair value of the design win milestones for TPI was $2.4 million which was recorded as a credit to research and development expense. Offsetting this amount is an increase in the fair value of two TPI cloud application milestones as a result of an increase in the estimated probability of achievement of those milestones. The increase in the fair value of the cloud application milestones was $1.1 million which was recorded as a debit to research and development expense. A design milestone for TPI was achieved and the payment of $1.9 million was made during the three and nine months ended December 27, 2015.

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 in fiscal 2015.

9. Goodwill and Intangible Assets

The Company monitors the recoverability of goodwill recorded in connection with acquisitions annually, or whenever events or changes in circumstances indicate the carrying value may not be recoverable. There were no changes in the carrying amount of goodwill since March 29, 2015. The Company performs the annual goodwill impairment analysis as of the first day of the third quarter of each fiscal year. As of and for the three months ended December 27, 2015, the Company concluded that the $139.2 million of goodwill was not impaired.

Purchased intangible assets subject to amortization consist primarily of developed technology, customer relationships and patents and are reported net of accumulated amortization. Developed technology, customer relationships and patents are amortized on a straight line basis over the estimated useful life of the assets. In-process research and development (“IPR&D”) is assessed for impairment until the development is completed and products are available for sale. The Company expects to complete the IPR&D projects at various dates during fiscal year 2016 at which time amortization will commence. The costs that the Company incurred on the IPR&D projects after the acquisition were expensed. During fiscal 2015, the Company recorded $0.8 million of impairment on IPR&D on the MEMS Microphone business. During the three and nine months ended September 2015, one of the IPR&D projects was released to production. Therefore, the IPR&D value allocated to this project of $3.3 million was transferred to developed technology. Further, the estimated useful life for this technology is five years.

10. Subsequent event

Subsequent to the quarter ended December 27, 2015, the Company acquired certain assets of a company and its affiliates involved in the development of navigation solutions. The total cash consideration associated with the acquisition was approximately $7 million. The Company also will record approximately $1 million contingent consideration that would be payable in the future should certain specified milestones be met. This acquisition is not significant to the Company’s results of operations.

We leverage our unique intellectual property in micro-electro-mechanical system (MEMS) design and manufacturing to reduce size, cost and power. Our proprietary algorithms improve speed and accuracy and our application programming interfaces (APIs) simplify the task of incorporating motion in end user applications.

While our solutions have broad applicability, we currently target the Mobile, Wearables, Smart Home, Gaming, Industrial, and Automotive markets. We utilize a fabless model, leveraging generally available CMOS and MEMS foundries and semiconductor packaging supply chains in combination with our own proprietary additions and improvements.

Our current strategy is to continue targeting consumer electronics and industrial markets with integrated motion and sound devices that meet or exceed the performance and cost requirements of customers, 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 for an extended period of time or at all. We do not receive long-term purchase commitments from any of our customers, all of whom purchase our products on a purchase 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 or customer device certification protocols. This dynamic 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 more likely to introduce it into others. Additionally, once a customer introduces one of our lower functionality sensors into their platforms, we believe they will become more likely to adopt our more advanced integrated MotionTracking and audio devices.

Net Revenue

We derive our net revenue from sales of our Motion and Sound solutions. We primarily sell our products through our worldwide sales organization. We also sell our products through an indirect channel of distributors that fulfill orders from manufacturers of consumer electronics devices, original design manufacturers and contract manufacturers (collectively referred to as “intermediaries”). When we reference customers in this report, we are referring to the manufacturers of consumer electronics devices to whom these intermediaries sell our products.

Net revenue	$	120,029	$	115,864	$	338,870	$	272,740

Net revenue increased by $4.2 million, or 4%, in the third quarter of fiscal 2016 and increased by $66.1 million, or 24%, in the nine months ended December 27, 2015 compared to the corresponding periods of fiscal 2015. The increases in net revenue were primarily due to higher shipment volume, partially offset by lower per unit average selling prices. Total unit shipments increased by 14% and 42% in the three and nine months ended December 27, 2015, respectively. Our overall average unit selling price for the three and nine months ended December 27, 2015 decreased 9% and 13%, respectively, 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 December 27, 2015, Apple Inc., or Apple and Samsung Electronics Co., Ltd., or Samsung accounted for 47% and 13% of net revenue, respectively. For the nine months ended December 27, 2015, Apple and Samsung accounted for 40% and 18% of net revenue, respectively. For the three months ended December 28, 2014, Apple and Samsung accounted for 45% and 24% of net revenue, respectively. For the nine months ended December 28, 2014, Apple and Samsung accounted for 29% and 28% of net revenue, respectively.

The net revenue decrease for the smartphone and tablet end market in the three months ended December 27, 2015 reflects a comparable year ago period that included an initial sales ramp at a key customer, combined with increased competition for market share across this market segment. The net revenue increase for the smartphone and tablet end market for the nine months ended December 27, 2015 reflects expansion of the smartphone portion of the handset market and increased adoption of our technologies in those devices during that time period. The net revenue growth to total net revenue for the optimal image stabilization end market in the three and nine months ended December 27, 2015 primarily reflects increased adoption of our technology for optical image stabilization in smartphone camera modules. The net revenue growth and contribution to total net revenue for the gaming and other end market in the three and nine months ended December 27, 2015 primarily reflects increased adoption and expansion of a range of consumer electronic products in this market.

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. Sales into named Asian countries constituted 47% and 54% of our net revenue in the three and nine months ended December 27, 2015, respectively, compared with 50% and 64% of our net revenue in the three and nine months ended December 28, 2014, respectively. The net revenue increases in the United States and China reflect growing demand for our products primarily by mobile device manufacturers and consumer electronic manufacturers.

We believe that a substantial percentage of our net revenue will continue to come from sales to customers and contract manufacturers 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 28, 2015 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.

% of net revenue		41	%		43	%		42	%		41	%

Gross profit decreased by $0.6 million in the third quarter of fiscal 2016 and increased by $28.3 million in the nine months ended December 27, 2015 as compared to the corresponding periods of fiscal 2015. In the three months ended December 27, 2015, gross profit decreased primarily due to a $2.0 million net inventory charge largely related to excess and obsolete inventories combined with decreases in average selling price per unit sold for comparable products, partially offset by an increase in unit sales of our products. In the nine months ended December 27, 2015, gross profit increased primarily due to a significant increase in unit sales of our products, partially offset by decreases in average selling price per unit sold for comparable products. Gross margin was negatively impacted by a $3.9 million and a $8.1 million net inventory charge largely related to excess and obsolete inventories in the nine month ended December 27, 2015 and December 28, 2014, respectively.

Gross profit as a percentage of net revenue, or gross margin, decreased in the third quarter of fiscal 2016 primarily due to a $2.0 million net inventory charge as compared to the three months ended December 28, 2014. Gross margin increased in the nine months ended December 27, 2015 primarily due to a $8.1 million inventory charge during the nine months ended December 28, 2014.

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, intellectual property license costs, reference design development 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

31

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 for the three months ended December 27, 2015 increased by $1.3 million, or 5%, as compared to the corresponding period last year. The increase was primarily attributable to a $0.7 million increase in third-party project and contractor costs associated with new product development, a $0.5 million increase in allocated infrastructure costs to support higher headcount, a $0.2 million increase in employee compensation and benefits costs mainly due to an increase in headcount and a $0.1 million increase in depreciation costs related to increased capital equipment during the three months ended December 27, 2015. Offsetting these increases was a $0.3 million decrease in engineering equipment costs during the three months ended December 27, 2015. Research and development headcount increased to 320 at December 27, 2015 from 291 at December 28, 2014.

Research and development expense for the nine months ended December 27, 2015 increased by $5.5 million, or 8%, compared to the corresponding period last year. The increase was primarily attributable to a $6.5 million increase in employee compensation and benefits costs mainly due to an increase in headcount in part from our acquisitions of Movea and TPI, a $2.2 million increase in third party project and contractor costs associated with new product development, a $1.3 million increase in allocated infrastructure costs to support higher headcount, a $0.6 million increase in depreciation costs related to increased capital equipment, a $0.5 million increase in facility costs due to expansion of global facilities, a $0.2 million increase in travel expense and a $0.2 million increase in engineering equipment costs. Offsetting these increases was a $5.3 million credit from contingent consideration adjustment related to our acquisitions (See Note 8 to Condensed Consolidated Financial Statements). Research and development expense for nine months ended December 28, 2014 included an $0.8 million write-off of in-process research and development costs.

Selling, General and Administrative

Selling, general and administrative expense primarily consists of personnel related expenses, 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 organizations.

Selling, general and administrative expense decreased by $1.3 million, or 8%, in the three months ended December 27, 2015 compared to the corresponding period last year. The decrease was primarily attributable to a $1.6 million decrease in outside services expenses primarily resulting from the Movea and TPI acquisition legal costs incurred in the third quarter of fiscal 2015 and a $0.3 million decrease in depreciation costs resulting from the asset disposal in the third quarter of fiscal 2015. Offsetting these decreases was a $0.4 million increase in equipment costs and a $0.2 million increase in marketing expenses. Selling, general and administrative headcount decreased to 153 at December 27, 2015 from 157 at December 28, 2014.

Selling, general and administrative expense increased by $1.2 million, or 3%, in the nine months ended December 27, 2015 compared to the corresponding period last year. The increase was primarily attributable to a $3.7 million increase in employee compensation and benefits costs mainly due to an average higher headcount in the nine months ended December 27, 2015, an increase of $0.4 million in allocated infrastructure costs, offset partially by a decrease of $2.8 million in outside expenses due primarily to legal costs resulting from the Movea and TPI acquisitions in the nine months ended December 28, 2014.

Other income (expense), net was $(35,000) and $(0.3) million for the three months ended December 27, 2015 and December 28, 2014, respectively. Other (expense), net decreased by $0.2 million due to higher interest income for the three months ended December 27, 2015 as compared to the corresponding period of last year. Other income (expense), net was $0.1 million and $1.1 million for the nine months ended December 27, 2015 and December 28, 2014, respectively. Other income, net decreased by $1.0 million primarily due to a $0.9 million gain on our recorded subsequent to acquisition on an equity investment in TPI during the nine months ended December 28, 2014.

In the three and nine months ended December 27, 2015, the Company recorded an income tax provision (benefit) of $5.1 million and $3.4 million, respectively. In the three and nine months ended December 28, 2014, the Company recorded an income tax provision (benefit) of ($2.7) million and ($1.9) million respectively. The Company’s estimated 2016 effective tax rate differs from the U.S. statutory rate primarily due to foreign tax differentials, a current year loss in the U.S., and was negatively affected by an increase in non-deductible stock option expense, and other deductible federal tax attributes.

33

Included in our gross unrecognized tax benefits balance of $29.9 million at December 27, 2015 are $27.3 million of tax positions which would affect income tax expense if recognized. As of December 27, 2015, approximately $2.6 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.

Over 90% of our revenues are derived from sales to customers located outside the U.S. A significant percentage of our pre-tax income in the three months ended December 27, 2015 and December 28, 2014 was generated internationally, primarily from our Cayman Island subsidiary, which is currently a zero tax jurisdiction. Since 2011, our Cayman Island subsidiary has procured the rights to manufacture and sell our products in non-US locations via an intercompany technology license arrangement with its U.S. parent company. In addition, the Company has not provided for U.S. federal income and foreign withholding taxes on undistributed earnings from its non-U.S. subsidiaries, as it is the practice and intention of the Company to reinvest the earnings of its non-U.S. subsidiaries in those operations. Our effective tax rate is highly dependent upon the geographic distribution of our worldwide earnings or losses, and the tax regulations in each geographic region. We expect that a large percentage of our consolidated pre-tax income will continue to be derived from, and reinvested in, our overseas operations. We anticipate that this pre-tax income will continue to be subject to foreign tax at significantly lower tax rates when compared to the United States federal statutory tax rate.

The Company had deferred tax assets related to Research and Development Credits and other tax attributes including accrued expenses and stock based compensation that can be used to offset taxable income in future periods and reduce our income taxes payable in those future periods. Realization of our deferred tax assets is dependent upon future federal, state and foreign taxable income. Many of those credit carryforwards will expire if they are not used within certain time periods. As of December 27, 2015, management determined that there is sufficient positive evidence to conclude that it is more likely than not that we will have sufficient taxable income in the future that will allow us to realize these DTAs. However, it is possible that some or all of these credits could ultimately expire unused, especially if our U.S. entity does not make a taxable profit, which has been limited mainly due to stock option deductions since the company went public. Therefore, unless we are able to generate sufficient taxable income from our U.S. operations, a substantial valuation allowance to reduce our U.S. DTAs may be required, which would materially increase our expenses in the period the allowance is recognized and materially adversely affect our results of operations and statement of financial condition. Our judgments regarding future profitability may change due to future market conditions, changes in U.S. or international tax laws and other factors. These changes, if any, may require possible material adjustments to these deferred tax assets, resulting in a reduction in net income or an increase in net loss in the period when such determinations are made.

The US Tax Court, on July 27, 2015, in Altera Corp. v. Commissioner, 145 T.C. No. 3 (2015), issued an opinion related to the portion of the Treasury regulations issued under IRC Section 482 requiring related-party participants in a cost-sharing arrangement to share stock-based compensation costs. A final decision has yet to be issued by the Tax Court due to other outstanding issues related to the case. At this time, the U.S. Department of the Treasury has not withdrawn the requirement to include stock-based compensation from its regulations. We have reviewed this case and its impact on the Company and concluded that no adjustment to the consolidated financial statements is appropriate at this time. We will continue to monitor ongoing developments and potential impacts to our consolidated financial statements.

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 28, 2015.

Liquidity and Capital Resources

As of December 27, 2015, we had $43.9 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, $26.4 million of the $43.9 million of cash and cash equivalents were held by our foreign subsidiaries as of December 27, 2015. 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 nine months ended December 27, 2015 and December 28, 2014 was as follows:

	Nine Months Ended
	December 27,			December 28,
	2015			2014
	(in thousands)
Net cash provided by operating activities	$	86,022		$	15,105

Net cash provided by financing activities		2,812			7,814
Net increase (decrease) in cash and cash equivalents	$	(41,760	)	$	39,032

Net Cash Provided by Operating Activities

Net cash provided by operating activities for the nine months ended December 27, 2015 of $86.0 million was primarily due to non-cash expenses of $43.6 million, a change in operating assets and liabilities of $40.6 million and a net income of $1.7 million. The non-cash expenses of $43.6 million consisted primarily of stock-based compensation of $25.9 million, depreciation and amortization of $16.3 million, non-cash interest expense of $6.0 million, deferred income tax assets of $1.6 million, partially offset by contingent consideration adjustment of $5.3 million and tax effect of employee benefit plan of $0.9 million. The changes in our net operating assets and liabilities of $40.6 million were primarily comprised of a net increase of $24.8 million in Accounts payable and Accrued liabilities mainly due to price discounts to a customer, a decrease of $13.4 million in Inventories and a decrease of $2.2 million in “Prepaid and other current assets”.

Net cash provided by operating activities for the nine months ended December 28, 2014 of $15.1 million is primarily due to non-cash expenses of $35.9 million partially offset by a net decrease in operating assets and liabilities of $19.4 million and a net loss of $1.5 million. The non-cash expenses of $35.9 million consisted primarily of stock-based compensation of $22.9 million, depreciation and amortization of $12.3 million, non-cash interest expense of $5.6 million, partially offset by deferred income tax assets of $5.2 million. The net decrease in operating assets and liabilities of $19.4 million consisted primarily of increases in Accounts receivable of $34.3 million, partially offset by increases in Accrued liabilities of $8.2 million and decreases in Inventories of $5.2 million. The increase in Accounts receivable is primarily attributable to an increase in net revenue.

Net Cash Provided By (Used In) Investing Activities

Net cash used in investing activities in the nine months ended December 27, 2015 of $130.6 million primarily reflected the purchase of available-for-sale investments of $239.3 million and the purchase of property and equipment of $6.2 million, partially offset by the sale and maturity of available-for-sale investments of $114.9 million.

Net cash provided by investing activities in the nine months ended December 28, 2014 of $16.1 million was primarily from the sale and maturity of available-for-sale investments of $112.7 million, partially offset by cash paid for acquisitions of $71.3 million (net of cash acquired), and purchase of property and equipment of $25.3 million.

35

Net Cash Provided by Financing Activities

Net cash provided by financing activities in the nine months ended December 27, 2015 of $2.8 million resulted primarily from proceeds from the issuance of common stock of $4.7 million partially offset by certain payments of contingent consideration related to the TPI acquisition of $1.9 million.

Net cash provided by financing activities in the nine months ended December 28, 2014 of $7.9 million resulted primarily from the proceeds from the issuance of common stock on stock options exercises and ESPP purchases.

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 December 27, 2015, we were not involved in any unconsolidated SPE transactions.

Warranties and Indemnification

In connection with the sale of our products in the ordinary course of business, we often make representations affirming, among other things, that our products do not infringe on the intellectual property rights of others, and agree to indemnify customers against third-party claims for such infringement. Further, our certificate of incorporation and bylaws require us to indemnify our officers and directors against any action that may arise out of their services in that capacity. We have not been subject to any material liabilities under such provisions and therefore believe that our exposure for these indemnification obligations is minimal. Accordingly, we have no liabilities recorded for these indemnity agreements as of December 27, 2015.

Contractual Obligations

The following table summarizes our outstanding contractual obligations as of December 27, 2015:

	Payments Due by Period

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 Consolidated Financial Statements included in the Annual Report on Form 10-K for a full description of the convertible senior notes.

Operating leases consist of contractual obligations from agreements for non-cancelable office space, net of future minimum lease income. Minimum sublease income from third parties was approximately $0.4 million and $1.1 million for the three and nine months ended December 27, 2015. In the event of the failure of a third party to comply with its obligations under the subleases, we remain contractually obligated, as primary lessee, under the lease.

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

Included in our gross unrecognized tax benefits balance of $29.9 million at December 27, 2015 are $27.3 million of tax positions which would affect income tax expense if recognized. As of December 27, 2015, approximately $2.6 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.

Recent Accounting Pronouncements

The information set forth under Note 1 — Organization and Summary of Significant Accounting Policies — of the Notes to Condensed Consolidated Financial Statements, included in Part I, Item 1 of this Quarterly Report, is hereby incorporated by reference herein.

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 29, 2015. Our exposure to market risk has not changed materially since March 29, 2015.

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.

Organization and Summary of Significant Accounting Policies

9 Months Ended

Dec. 27, 2015

Accounting Policies [Abstract]

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 sensor systems on a chip, including accelerometers, gyroscopes and microphones for the mobile, wearable, smart home, gaming, industrial, and automotive market segments.

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 29, 2015 included in the Company’s Annual Report on Form 10-K filed on May 28, 2015 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 29, 2015.

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 (“GAAP”), and include the Company’s accounts and the accounts of its 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 2015”) ended on March 29, 2015 (“March 2015”). The third fiscal quarter in each of the two most recent fiscal years ended on December 27, 2015 (“three months ended December 27, 2015”) and December 28, 2014 (“three months ended December 28, 2014”), respectively, and each quarter period included 13 weeks. Fiscal year 2016 is a 53-week fiscal year ending April 3, 2016 (“Fiscal 2016”). The extra week is included in our fourth fiscal quarter ended April 3, 2016.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP and applicable rules and regulations of the SEC regarding interim financial reporting. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations.

The condensed consolidated balance sheet as of March 29, 2015, included herein was derived from the audited financial statements as of that date, but does not include all disclosures required by GAAP. The unaudited interim condensed consolidated financial statements, in the opinion of management, reflect all normal recurring adjustments necessary to present fairly the Company’s financial position, results of operations, comprehensive income (loss) and cash flows for the interim periods. The results of operations for the period ended December 27, 2015 is not necessarily indicative of the results to be expected for the fiscal year ending April 3, 2016 or for any future year or interim period.

Use of Estimates

The preparation of the Company’s Condensed Consolidated Financial Statements and notes thereto in conformity with 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 notes thereto and the reported amounts of income and expenses during the reporting period. Significant estimates included in the Consolidated Financial Statements and notes thereto include income taxes, inventory valuation, stock-based compensation, goodwill, 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.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. In accordance with Accounting Standard Codification 350, the Company reviews goodwill for impairment at the reporting unit level on an annual basis or whenever events or changes in circumstances indicate the carrying value may not be recoverable. As the Company uses the market approach to assess impairment, its common stock price is an important component of the fair value calculation. The Company has determined that it has a single reporting unit for purposes of performing its goodwill impairment test. The Company performed its annual impairment test during the quarter ended December 27, 2015 and determined that its goodwill was not impaired.

Concentration of Credit Risk

The majority of the Company’s products are shipped through its distributors or contract manufacturers (collectively “intermediaries”), who are the legal counter-parties to our sales. When the Company references customers, sales and revenue in this report, the Company is referring to the manufacturers of consumer electronics devices who are the end customers for our products. However, any disclosure about the composition of the Company’s accounts receivable refers to the intermediaries. Some of the Company’s intermediaries may serve more than one of the Company’s customers. As a result, attempting to compare or correlate disclosures about our accounts receivable composition as of a particular date with the disclosures regarding revenues generated by our customers for the period ending on the same date can be difficult or misleading.

A distributor accounted for 69% of accounts receivable at December 27, 2015. A distributor and a customer accounted for 77% and 12% of accounts receivable, respectively, at December 28, 2014.

For the three months ended December 27, 2015, one customer accounted for 47% of net revenue and another customer accounted for 13% of net revenue. For the nine months ended December 27, 2015, one customer accounted for 40% of net revenue and another customer accounted for 18% of net revenue. For the three months ended December 28, 2014, one customer accounted for 45% of net revenue and another customer accounted for 24% of net revenue. For the nine months ended December 28, 2014, one customer accounted for 29% of net revenue and another customer accounted for 28% of net revenue.

Warranty

The Company offers one year standard warranty on its products. In selective cases, the warranty period could be extended to multiple years. The Company’s accrual for anticipated warranty costs has increased primarily due to an increase in unit sales volume and a commensurate increase in the volume of product returned under the warranty agreements. The accrual also 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 nine months ended December 27, 2015 and December 28, 2014:

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. In periods in which the Company has reported a net loss, the common stock equivalents are excluded from the calculation of diluted net loss per share of common stock as their effect is antidilutive under the treasury stock method.

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

Recent Accounting Pronouncements

On November 20, 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-17. The new guidance requires that all deferred tax assets and liabilities, along with any related valuation allowance for each tax-paying jurisdiction within each tax-paying component, be classified as noncurrent on the balance sheet. The new guidance will be effective for public business entities in fiscal years beginning after December 15, 2016, including interim periods within those years. Early adoption is permitted for all entities as of the beginning of an interim or annual reporting period. The Company does not expect this guidance to have significant impact on its consolidated financial statements.

Cash and Cash Equivalents [Abstract]

Cash Equivalents and Available-for-Sale Investments

2. Cash Equivalents and Available-for-Sale Investments

At December 27, 2015, cash and cash equivalents totaled $43.9 million, of which $33.0 million was cash and $10.9 million was cash equivalents invested in money market funds. At December 27, 2015, $26.4 million of the 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 December 27, 2015, the Company had short-term available-for-sale investments of $253.3 million which are held in the US entity.

At March 29, 2015, cash and cash equivalents totaled $85.6 million, of which $61.6 million was cash and $24.0 million was cash equivalents. At March 29, 2015, $47.7 million of the cash and cash equivalents were held by our foreign subsidiaries. Additionally, as of March 29, 2015, the Company had short-term available-for-sale investments of $129.9 million which are held in the US entity.

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 the Company’s 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:

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 nine months ended December 27, 2015:

	Nine Months Ended
	December 27, 2015			December 28, 2014
	(in thousands)
Beginning balance	$	9,124		$	—

Change in fair value and other		(5,307	)		875
Ending balance	$	1,909		$	16,909

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 achieving 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 initial 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.

During the nine months ended December 27, 2015, the fair value of contingent consideration declined by $5.3 million. The decline in fair value was the result of a reduction in the probability of a design win milestone associated with the Movea, S.A., (“Movea”) acquisition from 50% to 0% and a reduction in the probability of a design win associated with the Trusted Positioning, Inc. (“TPI”) acquisition from 50% to 0%. The decline in fair value of the design win milestones for Movea and TPI was $4.0 million and $2.4 million, respectively, which were recorded as a credit to research and development expense. The earn-out payments for the Movea and TPI’s design win milestones were not made as these mile stones were not met and expired during the nine months ended December 27, 2015. Offsetting this amount is an increase in the fair value of two TPI cloud application milestones as a result of an increase in the estimated probability of achievement of those milestones. The increase in the fair value of the cloud application milestones was $1.1 million which was recorded as a debit to research and development expense during the nine months ended December 27, 2015. A design milestone for TPI was achieved and the payment of $1.9 million was made during the three and nine months ended December 27, 2015.

Commitments and Contingencies

4. Commitments and Contingencies

Operating Lease Obligations

The Company has non-cancelable operating leases for its facilities through fiscal year 2022.

Future minimum lease payments, net of future minimum lease income, under operating leases as of December 27, 2015 are as follows:

	Amount
Fiscal Years Ending:	(in thousands)
2016 (remainder)	$	1,206

Total	$	26,226

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, net of the rent income from subleases of $0.4 million and $1.1 million, was approximately $1.1 million and $3.7 million for the three and nine months ended December 27, 2015, respectively. The Company’s rental expense under operating leases was approximately $1.3 million and $3.6 million for the three and nine months ended December 28, 2014, respectively.

Purchase Commitments

The Company has non-cancelable purchase commitments with its foundry vendors. Future minimum payments of $44.0 million under the purchase commitments as of December 27, 2015 are due in less than twelve months.

Legal Proceedings and Contingencies

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 litigation related to intellectual property and employment issues.

In January and March of 2015, purported shareholders filed five substantially similar class action complaints in the U.S. District Court, Northern District of California against the Company and two of the Company’s current and former executives (“Class Action Defendants”) (Jim McMillan v. InvenSense, Inc., et al. Case No. 3:15-cv-00084-JD, filed January 7, 2015; William Lendales v. InvenSense, Inc. et al., Case No. 3:15-cv-00142-VC, filed on January 12, 2015; Plumber & Steamfitters Local 21 Pension Fund v. InvenSense, Inc., et al., Case No. 5:15-cv-00249-BLF, filed on January 16, 2015; William B. Davis vs. InvenSense, Inc., et al., Case No. 5:15-cv-00425-RMW, filed on January 29, 2015; and Saratoga Advantage Trust Technology & Communications Portfolio v. InvenSense et al., Case No. 3:15-cv-01134, filed on March 11, 2015). On April 23, 2015, those cases were consolidated into a single proceeding which is currently pending in the U.S. District Court, Northern District of California and captioned In re InvenSense, Inc. Securities Litigation, Case No. 3:15-cv-00084-JD (the “Securities Case”), and the Vossen Group was designated as lead plaintiff. On May 26, 2015, the lead plaintiffs filed a consolidated amended class action complaint, which alleges that the defendants violated the federal securities laws by making materially false and misleading statements regarding our business results between July 29, 2014 and October 28, 2014, and seeks unspecified damages along with plaintiff’s costs and expenses, including attorneys’ fees. On June 25, 2015, the Class Action Defendants filed a motion seeking dismissal of the case and a hearing on that motion was held on October 7, 2015. The parties are awaiting the court’s decision.

In addition, in January and March of 2015, other purported shareholders filed three substantially similar shareholder derivative complaints against two of our current and former officers and several of our current directors, twice in the U.S. District Court, Northern District of California and once in Santa Clara Superior Court (George E Rollins v. Behrooz Abdi et al., Case No. 5:15-cv-00184-PSG, filed on January 13, 2015; Linda Karr v. Behrooz Abdi et al., Case No. 5:15-cv-00200-NC, filed on January 14, 2015; and Robert Bilbrey v. Behrooz Abdi et al., Case No. 1-15-CV-278742 was filed on March 20, 2015) (collectively, the “Derivative Cases”). In the Derivative Cases complaints, the plaintiffs make allegations similar to those presented in the Securities Case, but the plaintiffs asserts various state law causes of action, including claims of breach of fiduciary duty and unjust enrichment. The Company has undertaken an evaluation of these complaints. Plaintiffs in the Derivative Cases have agreed to an indefinite stay pending developments in the Securities Case. In light of the unresolved legal issues, while a loss is reasonably possible, the amount of any potential loss cannot be estimated. At this stage, the Company is unable to predict the outcome of this matter and, accordingly, cannot estimate the potential financial impact on the Company’s business, operating results, cash flows or financial position.

The semiconductor and MEMS industries are characterized by companies that hold large numbers of patents and other intellectual property rights and that vigorously pursue, protect and enforce intellectual property rights.

Robert Bosch GmbH (“Bosch”), one of the Company’s competitors, and the Company have each previously made generalized assertions of potential patent infringement by the other. On October 28, 2015, the Company and Bosch resolved all assertions of potential infringement between them and entered into a multi-year, worldwide patent cross license agreement for MEMS and sensor technologies, excluding patents covering InvenSense’s CMOS-MEMS eutectic bonding production process and Bosch’s two-layer porous silicon production process, and an upfront payment of $11.5 million to Bosch. The other terms of the settlement and the patent cross license agreement remain confidential and are not expected to have a material impact on our future results. Based on the status of the negotiations, the Company recognized a pre-tax charge of $11.7 million during the quarter ended June 28, 2015; there were no significant changes to the final terms which required any additional charge for prior periods to be recorded in the quarter ended December 27, 2015. In the future, other third parties may assert against the Company and its customers and distributors, their patent and other intellectual property rights to technologies that are important to our business.

The Company is not aware of any other pending legal matters or claims, individually or in the aggregate, that are expected to have a material adverse impact on its consolidated financial position, results of operations, or cash flows. However, the Company’s analysis of whether a claim may proceed to litigation cannot be predicted with certainty, nor can the results of litigation be predicted with certainty.

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 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 obligations 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 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 of $21.89 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 an 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 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 were allocated to the equity component of the Notes, $3.0 million of issuance costs paid to the initial purchaser were accounted for as a debt discount and $0.25 million of the issuance costs were classified as other non-current assets. Debt issuance costs were reclassified and presented in the balance sheet as a direct deduction from the carrying value of the debt liability, consistent with the presentation of a debt discount in the first quarter of the Company’s fiscal year 2016 pertaining to the requirement of ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs. 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 December 27, 2015, the remaining amortization period of the debt discount and the issuance costs is 2.8 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 Notes 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 the 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.

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 3.6 million shares for fiscal year 2016.

Under the 2011 Plan, 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 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 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 2011 Plan and 2004 Stock Incentive Plan are as follows (in thousands, except per share amounts):

	Options Issued and Outstanding			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (In Years)		Aggregate Intrinsic Value
Balance — March 29, 2015		8,307		$	12.99		7.60	$	29,817
Options granted		1,692			14.50
Exercised options		(397	)		6.58
Cancelled options		(522	)		13.87
Balance — December 27, 2015		9,080		$	13.50		7.37	$	8,690
Vested and expected to vest — December 27, 2015		8,318		$	13.26		7.26	$	8,654
Vested — December 27, 2015		4,490		$	11.43		6.39	$	8,265

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 consolidated statements of income 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. The Company used historical experience to estimate expected term. The expected volatility was based on the historical stock volatilities of the Company’s historical data with that of a peer group of publicly listed companies over a period equal to the expected terms. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term. The Company does not anticipate paying any cash dividends in the foreseeable future and, therefore, uses an expected dividend yield of zero.

The aggregate intrinsic value of the stock options exercised during the three and nine months ended December 27, 2015 was $0.2 million and $2.8 million, respectively. The aggregate intrinsic value of the stock options exercised during the three and nine months ended December 28, 2014 was $2.3 million and $16.5 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 $17.9 million at December 27, 2015, and will be amortized over a weighted-average remaining period of approximately 2.4 years. 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 nine months ended December 27, 2015 and December 28, 2014.

	Three Months Ended						Nine Months Ended
	December 27,			December 28,			December 27,			December 28,
	2015			2014			2015			2014
Expected term (in years)		5.2			5.0			5.1			4.5
Volatility		44.8	%		45.9	%		45.1	%		42.1	%
Risk-free interest rate		1.7	%		1.6	%		1.5	%		1.5	%
Dividend rate		0	%		0	%		0	%		0	%

The weighted-average grant date fair value of the Company’s stock options granted in the three and nine month ended December 27, 2015 was $4.35 and $5.97 per share, respectively. The weighted-average grant date fair value of the stock options granted in the three and nine months ended December 28, 2014 was $6.65 and $7.28 per share, respectively.

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 29, 2015		4,030		$	17.75
Granted		1,559			13.12
Released		(807	)		17.00
Forfeited		(550	)		17.83
Unvested at December 27, 2015		4,232		$	16.18

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 December 27, 2015, there was $43.6 million of total unrecognized compensation cost related to restricted stock units and restricted stock, which the Company expects to recognize over a period of 2.7 years. The weighted-average grant-date fair value per share of restricted stock units and restricted stock awarded in the three and nine months ended December 27, 2015 was $10.44 and $13.12 per share, respectively. The weighted-average grant-date fair value per share of restricted stock units and restricted stock awarded in the three and nine months ended December 28, 2014 was $16.25 and $21.08 per share, respectively.

2013 Employee Stock Purchase Plan

Under the 2013 Employee Stock Purchase Plan, effective September 13, 2013, (the “ESPP”), 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 ESPP 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 ESPP). Each offering period consists of one purchase period of approximately nine months duration.

At the 2015 annual meeting of stockholders, stockholders of the Company approved an amendment to the current ESPP to increase the number of shares of common stock reserved for future issuance by 1,000,000 shares which brought the total of common stock reserved for issuance to employees to an aggregate of 1,400,000 shares. As of December 27, 2015, 400,000 shares had been purchased.

During the three and nine months ended December 27, 2015, compensation expense recognized in connection with the Purchase Plan was $0.1 million and $0.6 million, respectively. During the three and nine months ended December 28, 2014, compensation expense recognized in connection with the Purchase Plan was $0.3 million and $0.7 million, respectively.

Common Stock

As of December 27, 2015 and March 29, 2015, common stock reserved for future issuance was as follows:

Common stock reserved for issuance	December 27, 2015		March 29, 2015,

Income Taxes

7. Income Taxes

In the three and nine months ended December 27, 2015, the Company recorded an income tax provision (benefit) of $5.09 million and $3.36 million, respectively In the three and nine months ended December 28, 2014, the Company recorded an income tax provision (benefit) of ($2.7) million and ($1.9) million respectively. The Company’s estimated 2016 effective tax rate differs from the U.S. statutory rate primarily due to foreign tax differentials, a current year loss in the U.S., and was negatively affected by an increase in non-deductible stock option expense, and other deductible federal tax attributes.

Over 90% of our revenues are derived from sales to customers located outside the U.S. A significant percentage of our pre-tax income in the three months ended December 27, 2015 and December 28, 2014 was generated internationally, primarily from our Cayman Island subsidiary, which is currently a zero tax jurisdiction. Since 2011, our Cayman Island subsidiary has procured the rights to manufacture and sell our products in non-US locations via an intercompany technology license arrangement with its U.S. parent company. In addition, the Company has not provided for U.S. federal income and foreign withholding taxes on undistributed earnings from its non-U.S. subsidiaries, as it is the practice and intention of the Company to reinvest the earnings of its non-U.S. subsidiaries in those operations. Our effective tax rate is highly dependent upon the geographic distribution of our worldwide earnings or losses, and the tax regulations in each geographic region. We expect that a large percentage of our consolidated pre-tax income will continue to be derived from, and reinvested in, our overseas operations. We anticipate that this pre-tax income will continue to be subject to foreign tax at significantly lower tax rates when compared to the United States federal statutory tax rate.

The Company had deferred tax assets related to Research and Development Credits and other tax attributes including accrued expenses and stock based compensation that can be used to offset taxable income in future periods and reduce our income taxes payable in those future periods. Realization of our deferred tax assets is dependent upon future federal, state and foreign taxable income. Many of those credit carryforwards will expire if they are not used within certain time periods. As of December 27, 2015, management determined that there is sufficient positive evidence to conclude that it is more likely than not that we will have sufficient taxable income in the future that will allow us to realize these deferred tax assets (“DTAs”). However, it is possible that some or all of these credits could ultimately expire unused, especially if our U.S. entity does not make a taxable profit, which has been limited mainly due to stock option deductions since the company went public. Therefore, unless we are able to generate sufficient taxable income from our U.S. operations, a substantial valuation allowance to reduce our U.S. DTAs may be required, which would materially increase our expenses in the period the allowance is recognized and materially adversely affect our results of operations and statement of financial condition. Our judgments regarding future profitability may change due to future market conditions, changes in U.S. or international tax laws and other factors. These changes, if any, may require possible material adjustments to these deferred tax assets, resulting in a reduction in net income or an increase in net loss in the period when such determinations are made.

The Company has not provided for U.S. federal income and foreign withholding taxes on undistributed earnings from non-U.S. operations as of December 27, 2015.

The Company has recorded $14.2 million of uncertain tax positions within “Other long-term liabilities” on the condensed consolidated balance sheet as at December 27, 2015. 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 is in the process of an Internal Revenue Service (“IRS”) examination for tax years 2011, 2012, 2013 and 2014. The Company may be subject to examination by California for tax years 2010 and forward. Generally, the Company is subject to routine examination for tax years 2008 and forward in various foreign tax jurisdictions in which it operates.

Business Combinations [Abstract]

Acquisition

8. Acquisition

The Company completed two acquisitions in fiscal 2015. The acquisitions have been accounted for using the acquisition method of accounting in accordance with ASC 805—Business Combinations. Under the acquisition method of accounting, the total purchase consideration of the acquisition is allocated to the tangible assets and identifiable intangible assets and liabilities assumed based on their relative fair values. The excess of the purchase consideration over the net tangible and identifiable intangible assets is recorded as goodwill, and was derived from expected benefits from future technology development, synergies and the knowledgeable and experienced workforce who joined the Company after the acquisition.

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 with the potential to pay an additional $13.0 million in cash contingent upon the achievement of certain milestones within one year of the acquisition.

The table below is a summary of the 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
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 included $2.6 million of long-term debt which was included in the long-term liabilities. The debt was measured at fair value using the effective interest rate method and considered as Level 3 inputs as defined in the fair value hierarchy, which approximates carrying value as of December 27, 2015.

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 before December 29, 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 and recorded in accrued liabilities. The product development milestone of $5.0 million was achieved and the payment was made in fiscal 2015. The difference between the contractual amount of $5.0 million and the fair value of this contingent consideration was recorded in the research and development expense for the year ended March 29, 2015. During the nine months ended December 27, 2015, the fair value of contingent consideration for Movea declined by $4.0 million. The decline in fair value was the result of a reduction in the probability of a design win milestone associated with the Movea acquisition from 50% to 0%. The decline in fair value of the design win milestones for Movea was recorded as a credit to research and development expense.

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 five 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 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 $25.9 million. The total purchase price, as presented in the table below, consists of (i) cash of $11.4 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.

The table below is a summary of the 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	$	11,379
Issuance of common stock		5,703
Contingent consideration		7,634
Fair value of previously held 4.57% equity interest		1,215
	$	25,931
Allocation of purchase price:

Developed technology		8,600
Goodwill		19,893
Current liabilities		(1,247	)
Long-term liabilities		(2,303	)
Total preliminary purchase price	$	25,931

The purchase price includes contingent consideration comprised of (i) $5.0 million payable upon a design win within one year of acquisition, (ii) $3.0 million payable upon achieving a development milestone before December 29, 2014, (iii) $2.0 million payable upon successful development of cloud application within two years of acquisition and (iv) $2.0 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 development milestone of $3 million was achieved and the payment was made in fiscal 2015. The difference between the contractual amount of $3.0 million and the fair value of this contingent consideration was recorded in the research and development expense for the year ended March 29, 2015.

During the nine months ended December 27, 2015, the fair value of contingent consideration for TPI declined by $1.3 million. The decline in fair value was the result of a reduction in the probability of a design win associated with the TPI acquisition from 50% to 0%. The decline in fair value of the design win milestones for TPI was $2.4 million which was recorded as a credit to research and development expense. Offsetting this amount is an increase in the fair value of two TPI cloud application milestones as a result of an increase in the estimated probability of achievement of those milestones. The increase in the fair value of the cloud application milestones was $1.1 million which was recorded as a debit to research and development expense. A design milestone for TPI was achieved and the payment of $1.9 million was made during the three and nine months ended December 27, 2015.

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 in fiscal 2015.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Intangible Assets

9. Goodwill and Intangible Assets

The Company monitors the recoverability of goodwill recorded in connection with acquisitions annually, or whenever events or changes in circumstances indicate the carrying value may not be recoverable. There were no changes in the carrying amount of goodwill since March 29, 2015. The Company performs the annual goodwill impairment analysis as of the first day of the third quarter of each fiscal year. As of and for the three months ended December 27, 2015, the Company concluded that the $139.2 million of goodwill was not impaired.

Purchased intangible assets subject to amortization consist primarily of developed technology, customer relationships and patents and are reported net of accumulated amortization. Developed technology, customer relationships and patents are amortized on a straight line basis over the estimated useful life of the assets. In-process research and development (“IPR&D”) is assessed for impairment until the development is completed and products are available for sale. The Company expects to complete the IPR&D projects at various dates during fiscal year 2016 at which time amortization will commence. The costs that the Company incurred on the IPR&D projects after the acquisition were expensed. During fiscal 2015, the Company recorded $0.8 million of impairment on IPR&D on the MEMS Microphone business. During the three and nine months ended September 2015, one of the IPR&D projects was released to production. Therefore, the IPR&D value allocated to this project of $3.3 million was transferred to developed technology. Further, the estimated useful life for this technology is five years.

Amortization for acquired intangible assets for the three and nine months ended December 27, 2015 was approximately $2.3 million and $6.8 million, respectively. Amortization for purchased intangible assets for the three months and nine months ended December 28, 2014 was approximately $2.0 million and $4.9 million respectively. The following table represents intangible assets and accumulated amortization:

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 sensor systems on a chip, including accelerometers, gyroscopes and microphones for the mobile, wearable, smart home, gaming, industrial, and automotive market segments.

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 29, 2015 included in the Company’s Annual Report on Form 10-K filed on May 28, 2015 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 29, 2015.

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 (“GAAP”), and include the Company’s accounts and the accounts of its 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 2015”) ended on March 29, 2015 (“March 2015”). The third fiscal quarter in each of the two most recent fiscal years ended on December 27, 2015 (“three months ended December 27, 2015”) and December 28, 2014 (“three months ended December 28, 2014”), respectively, and each quarter period included 13 weeks. Fiscal year 2016 is a 53-week fiscal year ending April 3, 2016 (“Fiscal 2016”). The extra week is included in our fourth fiscal quarter ended April 3, 2016.

Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP and applicable rules and regulations of the SEC regarding interim financial reporting. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations.

The condensed consolidated balance sheet as of March 29, 2015, included herein was derived from the audited financial statements as of that date, but does not include all disclosures required by GAAP. The unaudited interim condensed consolidated financial statements, in the opinion of management, reflect all normal recurring adjustments necessary to present fairly the Company’s financial position, results of operations, comprehensive income (loss) and cash flows for the interim periods. The results of operations for the period ended December 27, 2015 is not necessarily indicative of the results to be expected for the fiscal year ending April 3, 2016 or for any future year or interim period.

Use of Estimates

Use of Estimates

The preparation of the Company’s Condensed Consolidated Financial Statements and notes thereto in conformity with 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 notes thereto and the reported amounts of income and expenses during the reporting period. Significant estimates included in the Consolidated Financial Statements and notes thereto include income taxes, inventory valuation, stock-based compensation, goodwill, 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.

Goodwill

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. In accordance with Accounting Standard Codification 350, the Company reviews goodwill for impairment at the reporting unit level on an annual basis or whenever events or changes in circumstances indicate the carrying value may not be recoverable. As the Company uses the market approach to assess impairment, its common stock price is an important component of the fair value calculation. The Company has determined that it has a single reporting unit for purposes of performing its goodwill impairment test. The Company performed its annual impairment test during the quarter ended December 27, 2015 and determined that its goodwill was not impaired.

Concentration of Credit Risk

Concentration of Credit Risk

The majority of the Company’s products are shipped through its distributors or contract manufacturers (collectively “intermediaries”), who are the legal counter-parties to our sales. When the Company references customers, sales and revenue in this report, the Company is referring to the manufacturers of consumer electronics devices who are the end customers for our products. However, any disclosure about the composition of the Company’s accounts receivable refers to the intermediaries. Some of the Company’s intermediaries may serve more than one of the Company’s customers. As a result, attempting to compare or correlate disclosures about our accounts receivable composition as of a particular date with the disclosures regarding revenues generated by our customers for the period ending on the same date can be difficult or misleading.

A distributor accounted for 69% of accounts receivable at December 27, 2015. A distributor and a customer accounted for 77% and 12% of accounts receivable, respectively, at December 28, 2014.

For the three months ended December 27, 2015, one customer accounted for 47% of net revenue and another customer accounted for 13% of net revenue. For the nine months ended December 27, 2015, one customer accounted for 40% of net revenue and another customer accounted for 18% of net revenue. For the three months ended December 28, 2014, one customer accounted for 45% of net revenue and another customer accounted for 24% of net revenue. For the nine months ended December 28, 2014, one customer accounted for 29% of net revenue and another customer accounted for 28% of net revenue.

Warranty

Warranty

The Company offers one year standard warranty on its products. In selective cases, the warranty period could be extended to multiple years. The Company’s accrual for anticipated warranty costs has increased primarily due to an increase in unit sales volume and a commensurate increase in the volume of product returned under the warranty agreements. The accrual also 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 nine months ended December 27, 2015 and December 28, 2014:

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. In periods in which the Company has reported a net loss, the common stock equivalents are excluded from the calculation of diluted net loss per share of common stock as their effect is antidilutive under the treasury stock method.

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

Recent Accounting Pronouncements

Recent Accounting Pronouncements

On November 20, 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-17. The new guidance requires that all deferred tax assets and liabilities, along with any related valuation allowance for each tax-paying jurisdiction within each tax-paying component, be classified as noncurrent on the balance sheet. The new guidance will be effective for public business entities in fiscal years beginning after December 15, 2016, including interim periods within those years. Early adoption is permitted for all entities as of the beginning of an interim or annual reporting period. The Company does not expect this guidance to have significant 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.
