1. Organization and Basis of Presentation

Inphi Corporation (the “Company”), a Delaware corporation, was incorporated in November 2000. The Company is a fabless provider of high-speed analog and mixed signal semiconductor solutions for the communications, data center and computing markets. The Company’s semiconductor solutions are designed to address bandwidth bottlenecks in networks, maximize throughput and minimize latency in computing environments and enable the rollout of next generation communications, data center and computing infrastructures. In addition, the semiconductor solutions provide a vital high-speed interface between analog signals and digital information in high-performance systems such as telecommunications transport systems, enterprise networking equipment, data center and enterprise servers, storage platforms, test and measurement equipment and military systems.

The interim unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), for interim financial information and with the instructions to Securities and Exchange Commission (“SEC”), Form 10-Q and Article 10 of SEC Regulation S-X. They do not include all of the information and footnotes required by GAAP for complete financial statements. Therefore, these financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2015, included in the Company’s Annual Report on Form 10-K filed with the SEC on February 29, 2016.

The interim condensed consolidated financial statements included herein are unaudited; however, they contain all normal recurring accruals and adjustments that, in the opinion of management, are necessary to state fairly the Company’s consolidated financial position at June 30, 2016, and its consolidated results of operations for the three and six months ended June 30, 2016 and 2015 and cash flows for the six months ended June 30, 2016 and 2015. The results of operations for the three and six months ended June 30, 2016 are not necessarily indicative of the results to be expected for future quarters or the full year.

On June 29, 2016, the Company signed a definitive agreement to sell the memory product business to Rambus Inc. for $90,000 in cash inclusive of $11,250 which will be placed into escrow for a period of twelve months following the closing as security for the Company’s indemnification obligations pursuant to the agreement. The sale was completed on August 4, 2016. The Company's consolidated financial statements and accompanying notes for current and prior periods have been restated to present the results of operations of the memory product business as discontinued operations. In addition, the assets and liabilities to be disposed of have been treated and classified as held for sale. For more information on discontinued operations, see Note 3.

2. Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued guidance on “Revenue from Contracts with Customers.” The new revenue recognition guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. The guidance requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The new guidance was initially effective for the Company on January 1, 2017. The new guidance permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that the new revenue recognition guidance will have on the consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor determined the effect of the standard on the ongoing financial reporting. In July 2015, the FASB voted to defer the effective date of the new revenue recognition standard by one year. The guidance may be adopted as early as January 1, 2017, the effective date of the original guidance.

In July 2015, the FASB issued guidance applying to inventory measured using any other method other than last-in, last-out method. Under this guidance inventory is measured at the lower of cost and net realizable value. The net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The guidance is applied prospectively and is effective for the Company beginning January 1, 2017. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements and related disclosures.

In September 2015, the FASB issued guidance that requires an acquirer in a business combination to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The guidance also requires disclosure of the effect on earnings of changes in depreciation, amortization or other income effects, if any, as a result of the adjustment to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. This guidance is effective for the Company beginning January 1, 2016. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements and related disclosures.

(Dollars in thousands except share and per share amounts)

In January 2016, the FASB issued guidance that requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The guidance simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. The guidance eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, and requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. The guidance also requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. Separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements is required under this guidance. The guidance further clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The guidance is applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption and is effective for the Company in its first quarter of fiscal 2018. Early adoption is permitted only if certain criteria is met. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued guidance that requires companies that lease assets (lessees) to recognize on the balance sheet the assets and liabilities for the rights and obligations created by the leases with lease terms of more than 12 months. This guidance is effective for the Company beginning January 1, 2019. Early adoption is permitted. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements and related disclosures.

In March 2016, the FASB issued a guidance that eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The guidance require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The guidance also requires that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The guidance is effective for the Company beginning after January 1, 2017. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements and related disclosures.

In March 2016, the FASB issued a guidance in the assessment whether an entity is a principal or an agent in the new revenue standard (gross versus net revenue presentation). The guidance has the same effective date and transition requirements as the new revenue standard, which is effective for calendar year ¬end public companies in 2018 with early adoption permitted in 2017.

In March 2016, the FASB issued a guidance that will change certain aspects of accounting for share-based payments to employees. The new guidance requires all income tax effects of awards to be recognized in the income statement when the awards vest or are settled. It also allows an employer to repurchase more of an employee’s shares than the minimum for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The new guidance allows entities to estimate forfeiture or recognize forfeitures when they occur. It also requires presentation of excess tax benefits as an operating activity and cash paid by employer to taxing authorities on the employees’ behalf for withheld shares as financing activity on the statement of cash flows. The Company early adopted this standard at the beginning of 2016 and the effect of adoption is discussed in Note 13 of the condensed consolidated financial statements.

In April 2016, the FASB issued a guidance which amends the revenue guidance on identifying performance obligations and accounting for licenses of intellectual property. The guidance changed the previous proposals on renewals of right-of-use licenses and contractual restrictions. The guidance has the same effective date and transition requirements as the new revenue standard, which is effective for calendar year ¬end public companies in 2018 with early adoption permitted in 2017.

3.Discontinued Operations

In June 2016, the Company announced sale of its memory product business (the “Business”) to Rambus Inc. for $90,000 in cash, $11,250 of which will be placed into escrow for a period of the twelve months following the closing as security for the Company’s indemnification obligations pursuant to the Asset Purchase Agreement dated June 29, 2016. The sale was completed on August 4, 2016. The divestiture of the Business was part of a strategic plan to focus on and increase investments in the Company’s communication business. The assets and liabilities of the Business have been classified as held for sale and the results of operations are shown in net income (loss) from discontinued operations. The Company’s condensed consolidated financial statements and the accompanying notes for current and prior periods have been restated.

Total investments	$	180,654	$	180,900	$	43,677	$	43,616

As of June 30, 2016, the Company had 13 investments that were in an unrealized loss position. The gross unrealized losses on these investments at June 30, 2016 of $13 were determined to be temporary in nature. The Company reviews the investments to identify and evaluate investments that have an indication of possible other-than-temporary impairment. Factors considered in determining whether a loss is other-than-temporary include the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the investee, and the intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value.

The realized gain related to the Company’s available-for-sale investment which was reclassified from other comprehensive income was included in other income in the condensed consolidated statements of income.

The contractual maturities of available-for-sale securities at June 30, 2016 are presented in the following table:

	Cost		Fair Value

8. Product Warranty Obligation

As of June 30, 2016 and December 31, 2015, the product warranty liability was $110. There was no movement in product warranty liability during the three and six months ended June 30, 2016 and 2015.

9.Convertible debt

In December 2015, the Company issued $230,000 of 1.125% convertible senior notes due 2020 (Convertible Notes). The Convertible Notes will mature December 1, 2020, unless earlier converted or repurchased. Interest on the Convertible Notes is payable on June 1 and December 1 of each year, beginning on June 1, 2016. The initial conversion rate is 24.8988 shares of common stock per $1 principal amount of Convertible Notes, which represents an initial conversion price of approximately $40.16 per share. The total interest expense recognized for the three months ended June 30, 2016 was $3,171, which consists of $521 of contractual interest expense, $2,432 of amortization of debt discount and $218 of amortization of debt issuance costs. The total interest expense recognized for the six months ended June 30, 2016 was $6,303, which consists of $1,276 of contractual interest expense, $4,613 of amortization of debt discount and $414 of amortization of debt issuance costs.

In connection with the issuance of the Convertible Notes, the Company entered into capped call transactions (Capped Call) in private transactions. Under the Capped Call, the Company purchased capped call options that in aggregate relate to 100% of the total number of shares of the Company's common stock underlying the Convertible Notes, with a strike price equal to the conversion price of the Convertible Notes and with a cap price equal to $52.06 per share.

10. Other long-term liabilities

Other long-term liabilities consist of the following:

	June 30, 2016		December 31, 2015
Deferred rent	$	1,348	$	1,728
Income tax payable		1,589		6,969
	$	2,937	$	8,697

11. Income Taxes

The Company determined its interim provision using an estimated single annual effective tax rate for all tax jurisdictions for the three and six months ended June 30, 2016. For the three and six months ended June 30, 2015, the Company determined its interim tax provision applying a separate estimated annual effective tax rate to its loss jurisdictions. ASC 740 provides that when an entity operates in a jurisdiction that has generated ordinary losses on a year-to-date basis or on the basis of the results anticipated for the full fiscal year and no benefit can be recognized on those losses, a separate effective tax rate should be computed and applied to ordinary income (or loss) in that jurisdiction. The Company incurred pretax loss during the three and six months ended June 30, 2015 from the Singapore operation and did not recognize tax benefit of the losses due to full valuation allowance established against deferred tax assets. Thus, a separate effective tax rate was applied to the Singapore jurisdiction to compute the Company’s interim tax expense.

The Company recorded an income tax provision (benefit) from continuing operations of $303 and ($29) in the three and six months ended June 30, 2016, respectively. The effective tax rate for the three and six months ended June 30, 2016 was 24% and (4%), respectively. The difference between the effective tax rates and the 34% federal statutory rate was primarily due to the change in valuation allowance, foreign income taxes provided at lower rates, geographic mix in operating results, unrecognized tax benefits, recognition of federal and state research and development credits and windfall tax benefits from stock-based compensation from early adoption of Accounting Standards Update 2016-09. The Company recorded an income tax provision (benefit) from continuing operations of ($869) and $1,869 in the three and six months ended June 30, 2015, respectively. The effective tax rate for the three and six months ended June 30, 2015 was 61% and (19%), respectively. The difference between the effective tax rates and the 34% federal statutory rate was primarily due to the change in valuation allowance, foreign income taxes provided at lower rates, geographic mix in operating results, unrecognized tax benefits, stock-based compensation adjustments and recognition of state research and development credits.

During the three and six months ended June 30, 2016, the gross amount of the Company’s unrecognized tax benefits increased (decreased) by approximately $296 and ($1,588), respectively primarily due to a state tax audit settlement and expiration of the statute of limitations on certain foreign income taxes, partially offset by the results of tax positions taken during the current year. Substantially all of the unrecognized tax benefits as of June 30, 2016, if recognized, would affect the Company’s effective tax rate. The Company believes that in the next twelve months, it is reasonably possible that the gross unrecognized tax benefit may decrease by approximately $100 due to the expiration of statute of limitations on certain foreign income taxes.

The Company does not provide for U.S. income taxes on undistributed earnings of its controlled foreign corporations that are intended to be invested indefinitely outside the United States.

12. Earnings Per Share

The following shows the reconciliation of weighted average shares used in the calculation of basic and diluted earnings per share:

	Three Months Ended June 30,				Six Months Ended June 30,
	2016		2015		2016		2015
Weighted-average common stock—basic		40,412,319		38,431,307		40,085,260		38,065,942
Effect of potentially dilutive securities:
Add options to purchase common stock		1,324,796		—		1,327,237		—
Add unvested restricted stock unit		2,101,373		—		2,234,865		—
Add employee stock purchase plan		—		—		32,955		—
Weighted-average common stock—diluted		43,838,488		38,431,307		43,680,317		38,065,942

The following securities were not included in the computation of diluted earnings per share as inclusion would have been anti-dilutive:

	Three Months Ended June 30,				Six Months Ended June 30,
	2016		2015		2016		2015
Common stock options		—		2,615,744		—		2,774,985
Restricted stock unit		939,346		4,856,581		479,679		4,652,690
Convertible debt		5,727,092		—		5,727,092		—
		6,666,438		7,472,325		6,206,771		7,427,675

As discussed in Note 2, the Company early adopted ASU 2016-09. Based on the new guidance, the excess tax benefit is no longer included in the weighted diluted common stock calculation under the treasury stock method and therefore, increased the total weighted diluted common stock by 969,985 and 971,547 in the three and six months ended June 30, 2016, respectively. This change was applied prospectively.

13. Stock–Based Compensation

In June 2010, the Board of Directors (the “Board”) approved the Company’s 2010 Stock Incentive Plan (the “2010 Plan”), which became effective in November 2010. The 2010 Plan provides for the grants of restricted stock, stock appreciation rights and stock unit awards to employees, non-employee directors, advisors and consultants. The Compensation Committee administers the 2010 Plan, including the determination of the recipient of an award, the number of shares subject to each award, whether an option is to be classified as an incentive stock option or nonstatutory option, and the terms and conditions of each award, including the exercise and purchase prices and the vesting or duration of the award. Options granted under the 2010 Plan are exercisable only upon vesting. At June 30, 2016, 2,889,858 shares of common stock have been reserved for future grants under the 2010 Plan.

Stock Option Awards

The Company did not grant any stock options during the three and six months ended June 30, 2016 and 2015.

The following table summarizes information regarding options outstanding:

	Number of Shares			Weighted Average Exercise Price		Weighted Average Remaining Contractual Life		Aggregate Intrinsic Value
Outstanding at December 31, 2015		2,256,396		$	10.61		5.29	$	37,036
Granted		—			—
Exercised		(311,985	)		9.25
Canceled		(3,167	)		8.83
Outstanding at June 30, 2016		1,941,244		$	10.83		4.84	$	41,159
Exercisable at June 30, 2016		1,897,477		$	10.84		4.79	$	40,207
Vested and expected to vest at June 30, 2016		1,941,021		$	10.83		4.84	$	41,155

The intrinsic value of options outstanding, exercisable and vested and expected to vest is calculated based on the difference between the exercise price and the fair value of the Company’s common stock as of the respective balance sheet dates.

The total intrinsic value of options exercised during the six months ended June 30, 2016 and 2015 was $6,855 and $7,971, respectively. The intrinsic value of exercised options is calculated based on the difference between the exercise price and the fair value of the Company’s common stock as of the exercise date. Cash received from the exercise of stock options was $2,607 and $4,469, respectively, for the six months ended June 30, 2016 and 2015.

Restricted Stock Units and Awards

The Company granted restricted stock units (“RSUs”) to members of the Board and employees. Most of the Company’s outstanding RSUs vest over four years with vesting contingent upon continuous service. The Company estimates the fair value of RSUs using the market price of the common stock on the date of the grant. The fair value of these awards is amortized on a straight-line basis over the vesting period.

The following table summarizes information regarding outstanding restricted stock units:

	Number of Shares			Weighted Average Grant Date Fair Value Per Share
Outstanding at December 31, 2015		4,600,869		$	15.37
Granted		1,394,799			32.68
Vested		(1,205,465	)		14.31
Canceled		(297,315	)		17.38
Outstanding at June 30, 2016		4,492,888		$	20.89
Expected to vest at June 30, 2016		4,378,136

The RSUs include performance-based stock units subject to achievement of pre-established revenue goal and earnings per share on non-GAAP basis. Once the goals are met, the performance-based stock units are subject to four years of vesting from the original grant date, contingent upon continuous service. The total performance-based units that vested for the three and six months ended June 30, 2016 was 31,786. As of June 30, 2016, the total performance-based units outstanding was 300,356.

Employee Stock Purchase Plan

In December 2011, the Company adopted the Employee Stock Purchase Plan (“ESPP”). Participants purchase the Company's stock using payroll deductions, which may not exceed 15% of their total cash compensation. Pursuant to the terms of the ESPP, the "look-back" period for the stock purchase price is six months. Offering and purchase periods will begin on February 10 and August 10 of each year. Participants will be granted the right to purchase common stock at a price per share that is 85% of the lesser of the fair market value of the Company's common stock at the beginning or the end of each six-month period.

Table Of Contents

Inphi Corporation

Notes to Unaudited Condensed Consolidated Financial Statements

(Dollars in thousands except share and per share amounts)

The ESPP imposes certain limitations upon an employee’s right to acquire common stock, including the following: (i) no employee shall be granted a right to participate if such employee immediately after the election to purchase common stock, would own stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company, and (ii) no employee may be granted rights to purchase more than $25 fair value of common stock for each calendar year. The maximum aggregate number of shares of common stock available for purchase under the ESPP is 1,750,000 shares. The total common stock issued under the ESPP during the six months ended June 30, 2016 and 2015 was 164,696 and 160,776, respectively.

The fair value of the ESPP is estimated at the start of offering period using the Black-Scholes option pricing model with the following assumptions:

	Six Months Ended June 30,
	2016			2015
Risk-free interest rate		0.45	%		0.07	%
Expected life (in years)		0.50			0.50
Dividend yield		—			—
Expected volatility		55	%		41	%
Estimated fair value	$	7.26		$	5.34

Stock-Based Compensation Expense

Stock-based compensation expense is included in the Company’s results of operations as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2016		2015		2016		2015
Operating expenses
Cost of goods sold	$	426	$	358	$	761	$	696
Research and development		4,684		3,510		8,398		6,546
Sales and marketing		952		884		1,728		1,641
General and administrative		662		1,375		1,835		2,621
Discontinued operations		1,056		1,075		2,010		2,118
	$	7,780	$	7,202	$	14,732	$	13,622

Total unrecognized compensation cost related to unvested stock options, restricted stock units and awards at June 30, 2016, prior to the consideration of expected forfeitures, is approximately $79,366 and is expected to be recognized over a weighted-average period of 2.95 years.

The Company early adopted Accounting Standards Update 2016-09. The effect of adoption resulted to a net credit of $5,261 on the beginning balance of accumulated deficit from previously unrecorded deferred tax assets for net operating loss carryover generated by windfall tax benefit. The adoption increased weighted average diluted common stock by 969,985 and 971,547 in the three and six months ended June 30, 2016, respectively. In addition, the current period’s excess tax benefit related to stock-based compensation is presented as operating activity in the statement of cash flows. The change in the cash flow was adopted retrospectively and the Company reclassified $829 of excess tax benefit for the six months ended June 30, 2015 from financing activity to operating activity.

14. Fair Value Measurements

The guidance on fair value measurements requires fair value measurements to be classified and disclosed in one of the following three categories:

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: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

The Company measures its investments in marketable securities at fair value using the market approach, which uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The Company has cash equivalents which consist of money market funds valued using the amortized cost method, in accordance with Rule 2a-7 under the 1940 Act, which approximates fair value.

The Company determines the amount of transfers between Levels 1 and 2 or transfers into or out of Level 3 by using the end-of-period fair value. The Company had no transfers among the fair value hierarchy during the three and six months ended June 30, 2016.

The following table presents information about assets required to be carried at fair value on a recurring basis:

The Convertible Notes are not marked to fair value at the end of each reporting period. As of June 30, 2016 and December 31, 2015, the fair value of Convertible Notes was determined on the basis of market prices observable for similar instruments and is considered Level 2 in the fair value hierarchy.

As of June 30, 2016, the total value of open purchase orders for wafers was approximately $9,394.

Legal Proceedings

Netlist, Inc. v. Inphi Corporation, Case No. 09-cv-6900 (C.D. Cal.)

On September 22, 2009, Netlist filed suit in the United States District Court, Central District of California, or the Court, asserting that the Company infringes U.S. Patent No. 7,532,537. Netlist filed an amended complaint on December 22, 2009, further asserting that the Company infringes U.S. Patent Nos. 7,619,912 and 7,636,274, collectively with U.S. Patent No. 7,532,537, the patents-in-suit, and seeking both unspecified monetary damages to be determined and an injunction to prevent further infringement. These infringement claims allege that the iMB™ and certain other memory module components infringe the patents-in-suit. The Company answered the amended complaint on February 11, 2010 and asserted that the Company does not infringe the patents-in-suit and that the patents-in-suit are invalid. In 2010, the Company filedinter partes requests for reexamination with the United States Patent and Trademark Office (the “USPTO”), asserting that the patents-in-suit are invalid. As a result of the proceedings at the USPTO, the Court has stayed the litigation, with the parties advising the Court on status every 120 days.

As to the proceeding at the USPTO, reexamination has been ordered for all of the patents that were alleged to infringe, and at present, the USPTO has determined that almost all of the originally filed claims are not valid, with certain amended claims being determined patentable. It is expected that a Reexamination Certificate will issue for U.S. Patent No. 7,532,537 based upon amended claims, and the parties continue to assert their respective positions with respect to the reexamination proceedings for U.S. Patent Nos. 7,619,912 and 7,636,274.

While the Company intends to defend the foregoing USPTO proceedings and lawsuit vigorously, the USPTO proceedings and litigation, whether or not determined in the Company’s favor or settled, could be costly and time-consuming and could divert management’s attention and resources, which could adversely affect the Company’s business.

Based on the nature of USPTO proceedings and litigation, the Company is currently unable to predict the final outcome of this lawsuit and therefore, cannot determine the likelihood of loss nor estimate a range of possible loss. However, because of the nature and inherent uncertainties of litigation, should the outcome of these actions be unfavorable, the Company’s business, financial condition, results of operations or cash flows could be materially and adversely affected.

Indemnifications

In the ordinary course of business, the Company may provide indemnifications of varying scope and terms to customers, vendors, lessors, investors, directors, officers, employees and other parties with respect to certain matters, including, but not limited to, losses arising out of the Company’s breach of such agreements, services to be provided by the Company, or from intellectual property infringement claims made by third-parties. These indemnifications may survive termination of the underlying agreement and the maximum potential amount of future payments the Company could be required to make under these indemnification provisions may not be subject to maximum loss clauses. The Company has not incurred material costs to defend lawsuits or settle claims related to these indemnifications. Accordingly, the Company has no liabilities recorded for these agreements as of June 30, 2016 and December 31, 2015.

17. Subsequent Events

On August 4, 2016, the Company completed the sale of its memory product business to Rambus Inc. In connection with the sale, the Company entered into a transition service agreement with Rambus Inc. under which the Company will provide certain services on an interim, transitional basis, for a period of six months. The gain from the sale of the memory product business is expected to be material which will be reported in the third quarter of 2016.

Quarterly Update

As discussed in more detail below, for the three and six months ended June 30, 2016 compared to the three and six months ended June 30, 2015, we delivered the following financial performance:

•

Revenue from continuing operations increased by $11.0 million, or 22%, to $60.5 million in the three months ended June 30, 2016. In the six months ended June 30, 2016, total revenue increased by $22.2 million, or 24%, to $114.6 million.

•

Gross profit from continuing operations as a percentage of revenue increased to 68.2% from 64.6% in the three months ended June 30, 2016. In the six months ended June 30, 2016, gross profit as a percentage of revenue increased to 68.2% from 57.1%.

•

Total operating expenses from continuing operations increased by $3.9 million, or 12%, to $37.2 million in the three months ended June 30, 2016. In the six months ended June 30, 2016, total operating expenses increased by $9.2 million, or 15%, to $72.0 million.

•

Income from continuing operations increased by $5.3 million, or 403%, to $4.0 million in the three months ended June 30, 2016. In the six months ended June 30, 2016, income from operations increased by $16.3 million, or 162%, to $6.2 million.

•

Diluted earnings per share from continuing operations increased by $0.03 from ($0.01) in the three months ended June 30, 2016. In the six months ended June 30, 2016, diluted earnings per share increased by $0.33 from ($0.31).

The increase in our revenue for the three and six months ended June 30, 2016 was a result of the increase in consumption of our dual linear transimpedance amplifiers (TIA), quad linear driver products and complementary metal oxide semiconductor based 100G physical layers (iPHY) products.

The increase in gross margin was due to increase in sale of high margin products as discussed above and lower product cost from the inventory fair value step-up related to the acquired Cortina inventories for the three and six months ended June 30, 2016.

Total operating expenses increased due primarily to an increase in headcount and stock-based compensation expense. Our expenses primarily consist of personnel costs, which include compensation, benefits, payroll related taxes and stock-based compensation. From July 2015 to June 2016, our headcount increased by 20 new employees, primarily in the engineering department. We expect expenses to continue to increase in absolute dollars as we continue to invest resources to develop more products and to support the growth of our business. Our diluted earnings per share increased primarily due to increase in revenue partially offset by increase in operating expenses.

Our cash and cash equivalents were $146.9 million at June 30, 2016, compared with $283.0 million at December 31, 2015. Cash provided by operating activities was $24.7 million during the six months ended June 30, 2016 compared to $26.6 million during the six months ended June 30, 2015. Cash used in investing activities during the six months ended June 30, 2016 was $152.0 million primarily due to purchases of marketable securities of $171.7 million and purchases of property and equipment of $11.8 million offset by sales and maturities of marketable securities of $33.5 million and cost method investment of $2.0 million. Cash used in financing activities of $8.9 million was primarily due to minimum tax withholding paid on behalf of employees of $13.6 million and loan to supplier of $0.7 million offset by proceeds from the exercise of stock options and employee stock purchase plan of $5.8 million.

Critical Accounting Policies and Estimates

The preparation of financial statements in accordance with U.S. generally accepted accounting principles, or GAAP, requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of net revenue and expenses in the reporting period. We regularly evaluate our estimates and assumptions related to allowances for doubtful accounts, warranty reserves, inventory reserves, stock-based compensation expense, goodwill and intangible assets valuation, deferred income tax asset valuation allowances, uncertain tax positions, litigation, other loss contingencies and business combinations. We base our estimates and assumptions on current facts, historical experience and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of revenue, costs and expenses that are not readily apparent from other sources. The actual results experienced by us may differ materially and adversely from our estimates. To the extent there are material differences between our estimates and the actual results, our future results of operations will be affected. For a description of our critical accounting policies and estimates, please refer to the “Critical Accounting Policies and Estimates” section of our Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our Annual Report on Form 10-K for the year ended December 31, 2015. There have been no material changes in any of our critical accounting policies during the six months ended June 30, 2016. We early adopted Accounting Standards Update 2016-09, Improvements to Employee Share-Based Payment Accounting. The effect of adoption is discussed in Note 13 of Notes to Unaudited Condensed Consolidated Financial Statements.

Research and development expenses for the three and six months ended June 30, 2016 increased compared to the corresponding 2015 periods primarily due to the increase in research and development headcount, salaries and equity awards, which resulted in a $2.5 million and $4.0 million increase in personnel costs and stock-based compensation expense, respectively. CAD software tool license expense increased by $0.7 million and $0.9 million for the three and six months ended June 30, 2016, respectively, due mainly to increased headcount in engineering. Reimbursement from customers related to research and development contracts decreased by $2.5 million and $5.2 million for the three and six months ended June 30, 2016, respectively. For the six months ended June 30, 2016, laboratory supplies consumption increased by $1.2 million due to increase in research projects. The increases were partially offset by the abandonment of the project related to in-process research and development costs which resulted in an impairment charge of $1.8 million for the three and six months June 30, 2015. The increase in research and development expense was primarily driven by our strategy to expand our product offerings and enhance our existing product offerings.

General and administrative expenses for the three and six months ended June 30, 2016 decreased compared to the corresponding 2015 periods due to decrease in stock-based compensation expense by $0.7 million and $0.8 million, respectively mainly from vesting of grant to an officer. In the six months ended June 30, 2016, outside legal and accounting fees decreased by $0.6 million in connection with the completion of the Cortina acquisition and reduced expenditures for litigation matters described in Note 16 of the notes to our condensed consolidated financial statements. In the three and six months ended June 30, 2015, we incurred a loss of $0.5 million from the disposal of certain property and equipment from the Cortina acquisition.

Provision (benefit) for income taxes	$	(29	)	$	1,869	$	(1,898	)		(102%	)

We determined the interim provision using an estimated single annual effective tax rate for all tax jurisdictions for the three and six months ended June 30, 2016. For the three and six months ended June 30, 2015, we determined our interim tax provision applying a separate estimated annual effective tax rate to its loss jurisdictions. ASC 740 provides that when an entity operates in a jurisdiction that has generated ordinary losses on a year-to-date basis or on the basis of the results anticipated for the full fiscal year and no benefit can be recognized on those losses, a separate effective tax rate should be computed and applied to ordinary income (or loss) in that jurisdiction. We incurred pretax loss during the three and six months ended June 30, 2015 for the Singapore operations and will not recognize tax benefit of the losses due to full valuation allowance established against deferred tax assets. Thus, a separate effective tax rate was applied to the Singapore jurisdiction to compute the interim tax expense.

Table Of Contents

The income tax provision (benefit) from continuing operations for the three and six months ended June 30, 2016 reflects an effective tax rate of 24% and (4%), respectively. The effective tax rates for the three and six months ended June 30, 2016 differs from the statutory rate of 34% primarily due to the change in valuation allowance, foreign income taxes provided at lower rates, geographic mix in operating results, unrecognized tax benefits, recognition of federal and state research and development credits and windfall tax benefits from stock-based compensation from early adoption of Accounting Standards Update 2016-09.

The income tax provision (benefit) from continuing operations for the three and six months ended June 30, 2015 reflects an effective tax rate of 61% and (19%), respectively. The effective tax rates for the three and six months ended June 30, 2015 differs from the statutory rate of 34% primarily due to the change in valuation allowance, foreign income taxes provided at lower rates, geographic mix in operating results, unrecognized tax benefits and recognition of state research and development credits.

Liquidity and Capital Resources

As of June 30, 2016, we had cash, cash equivalents and investments in marketable securities of $327.8 million. Our primary uses of cash are to fund operating expenses, purchase inventory and acquire property and equipment. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the changes in our outstanding accounts payable and accrued expenses. Our primary sources of cash are cash receipts on accounts receivable from our revenue. In 2015, we issued convertible debt, which resulted in an increase in cash, cash equivalents and investments in marketable securities. 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.

The following table summarizes our cash flows for the periods indicated:

	Six Months Ended June 30,
	2016			2015
	(in thousands)
Net cash provided by operating activities	$	24,700		$	26,568
Net cash used in investing activities		(151,959	)		(5,704	)
Net cash used in financing activities		(8,871	)		(1,589	)
Net increase (decrease) in cash and cash equivalents	$	(136,130	)	$	19,275

Net Cash Provided by Operating Activities

Net cash provided by operating activities during the six months ended June 30, 2016 primarily reflected depreciation and amortization of $15.0 million, stock-based compensation expense of $14.7 million, accretion of convertible debt of $5.0 million and increase in accounts payable of $1.5 million partially offset by increases in accounts receivable of $8.6 million, prepaid expenses and other assets of $1.0 million and decrease in accrued expenses of $2.5 million. Our accounts payable increased due to increased production volume. Our accounts receivable increased due to higher product shipments to customers. Our accrued expenses decreased due to the timing of payment of employee related expenses. Our prepaid expenses and other assets increased due to additional subscriptions.

Net cash provided by operating activities during the six months ended June 30, 2015 primarily reflected depreciation and amortization of $12.9 million, stock-based compensation of $13.6 million, impairment of in-process research and development costs of $1.8 million, decreases in accounts receivable by $1.4 million, inventories by $2.3 million and prepaid expenses by $1.7 million, and change in income tax payable/receivable of $1.3 million, partially offset by net loss of $9.7 million. Our receivables decreased due to collections from customers. Our inventories decreased due to shipments to customers. Our prepaid expenses and other assets decreased due to settlement of a non-trade receivable.

Net Cash Used in Investing Activities

Net cash used in investing activities during the six months ended June 30, 2016 consisted of cash used to purchase property and equipment of $11.8 million and purchases of marketable securities of $171.7 million and cost method investment of $2.0 million, partially offset by sales and maturities of marketable securities of $33.5 million.

Net cash used in investing activities during the six months ended June 30, 2015, consisted of cash used to purchase property and equipment of $6.6 million and purchases of marketable securities of $7.9 million, offset by sales and maturities of marketable securities of $8.8 million.

Table Of Contents

Net Cash Used in Financing Activities

Net cash used in financing activities during the six months ended June 30, 2016 consisted of minimum tax withholding paid on behalf of employees for restricted stock units of $13.6 million, payment of costs related to debt issuance of $0.4 million, loan to supplier of $0.7 million partially offset by proceeds from the exercise of stock options and employee stock purchase plan of $5.8 million.

Net cash used in financing activities during the six months ended June 30, 2015 consisted of minimum tax withholding paid on behalf of employees for restricted stock units of $8.0 million, partially offset by proceeds from the exercises of stock options and employee stock purchase plan of $6.4 million.

Operating and Capital Expenditure Requirements

Our principal source of liquidity as of June 30, 2016 consisted of $327.8 million of cash, cash equivalents and investments in marketable securities, of which $29.5 million is held by our foreign subsidiaries. Based on our current operating plan, we believe that our existing cash and cash equivalents from operations will be sufficient to finance our operational cash needs through at least the next 12 months. In the future, we expect our operating and capital expenditures to increase as we increase headcount, expand our business activities and grow our end customer base which will result in higher needs for working capital. Our ability to generate cash from operations is also subject to substantial risks described in Part II, Item 1A, Risk Factors. If any of these risks occur, we may be unable to generate or sustain positive cash flow from operating activities. We would then be required to use existing cash and cash equivalents to support our working capital and other cash requirements. If additional funds are required to support our working capital requirements, acquisitions or other purposes, we may seek to raise funds through debt financing or from other sources. If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders could be significantly diluted, and these newly-issued securities may have rights, preferences or privileges senior to those of existing stockholders. If we raise additional funds by obtaining loans from third parties, the terms of those financing arrangements may include negative covenants or other restrictions on our business that could impair our operating flexibility, and would also require us to incur interest expense. We can provide no assurance that additional financing will be available at all or, if available, that we would be able to obtain additional financing on terms favorable to us.

We do not plan to repatriate cash balances from foreign subsidiaries to fund our operations in the United States. There may be adverse tax effects upon repatriation of these funds to the United States.

Contractual Payment Obligations

Our contractual obligations for 2016 and beyond are included in our Annual Report on Form 10-K for the year ended December 31, 2015, filed with the SEC on February 29, 2016. See note 16 of the notes to our unaudited condensed consolidated financial statements for information regarding obligations as of June 30, 2016.

Off-Balance Sheet Arrangements

At June 30, 2016, we had no material off-balance sheet arrangements, other than our facility operating leases.

Recent Authoritative Accounting Guidance

See note 2 of the notes to our unaudited condensed consolidated financial statements for information regarding recently issued accounting pronouncements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Sensitivity

We had cash and cash equivalents and investments in marketable securities of $327.8 million and $326.7 million at June 30, 2016 and December 31, 2015, respectively, which was held for working capital purposes. Our exposure to market interest-rate risk relates primarily to our investment portfolio. We do not use derivative financial instruments to hedge the market risks of our investments. We manage our total portfolio to encompass a diversified pool of investment-grade securities to preserve principal and maintain liquidity. We place our investments with high-quality issuers, money market funds and debt securities. Our investment portfolio as of June 30, 2016 consisted of money market funds, U.S. Treasuries, municipal bonds, corporate/government agency bonds, commercial papers and asset backed securities. Investments in both fixed rate and floating rate instruments carry a degree of interest rate risk. Fixed rate securities may have their market value adversely impacted due to an increase in interest rates, while floating rate securities may produce less income than expected if interest rates fall. Due in part to these factors, our future investment income may fall short of expectations due to changes in interest rates or if the decline in fair value of our publicly traded debt investments is judged to be other-than-temporary. We may suffer losses in principal if we are forced to sell securities that have declined in market value due to changes in interest rates. However, because any debt securities we hold are classified as available-for-sale, no gains or losses are realized in the income statement due to changes in interest rates unless such securities are sold prior to maturity or unless declines in value are determined to be other-than-temporary. These securities are reported at fair value with the related unrealized gains and losses, net of applicable taxes, included in accumulated other comprehensive income (loss), reported in a separate component of stockholders' equity. Although, we currently expect that our ability to access or liquidate these investments as needed to support our business activities will continue, we cannot ensure that this will not change.

Table Of Contents

In a low interest rate environment, as short-term investments mature, reinvestment may occur at less favorable market rates. Given the short-term nature of certain investments, the current interest rate environment may negatively impact our investment income.

Foreign Currency Risk

To date, our international customer and vendor agreements have been denominated almost exclusively in United States dollars. Accordingly, we have limited exposure to foreign currency exchange rates and currently enter into immaterial foreign currency hedging transactions.

Item 4. Controls and Procedures

Evaluation of disclosure controls and procedures

We maintain “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) under the Securities Exchange Act 1934, or the Exchange Act, that are designed to ensure that information required to be disclosed by us in reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer (our principal executive officer) and Chief Financial Officer (our principal financial officer), as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that such controls and procedures, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Our disclosure controls and procedures have been designed to meet reasonable assurance standards, but management does not expect that our disclosure controls and procedures will prevent or detect all error and all fraud. Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any disclosure controls and procedures is also 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.

Based on their evaluation as of the end of the period covered by this Quarterly Report on Form 10-Q, our Chief Executive Officer (our principal executive officer) and Chief Financial Officer (our principal financial officer) have concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1.Legal Proceedings

The information required by this Item 1 is set forth under Note 16 of Notes to Unaudited Condensed Consolidated Financial Statements, included in Part I, Item 1 of this Report, and is hereby incorporated by reference herein. For an additional discussion of certain risks associated with legal proceedings, see Item 1A. Risk Factors, below.

Item 1A.Risk Factors

You should carefully consider the risks described in Part I, Item 1A, Risk Factors, of our Annual Report on Form 10-K for the year ended December 31, 2015, which are incorporated by reference herein, as our business, financial condition and results of operations could be adversely affected by any of the risks and uncertainties described therein.

Table Of Contents

We may sell one or more of our product lines, from time to time, as a result of our evaluation of our products and markets, and any such divestiture could adversely affect our continuing business and our expenses, revenues, results of operation, cash flows and financial position.

We periodically evaluate our various product lines and may, as a result, consider the divestiture of one or more of those product lines. For example, in June 2016, we entered into an asset purchase agreement with Rambus, Inc. pursuant to which we agreed to sell our memory product business for $90 million in cash. Any such divestiture could adversely affect our continuing business and expenses, revenues, results of operations, cash flows and financial position.

Divestitures of product lines have inherent risks, including the expense of selling the product line, the possibility that any anticipated sale will not occur, delays in closing any sale, the risk of lower-than-expected proceeds from the sale of the divested business, unexpected costs associated with the separation of the business to be sold from the seller’s information technology and other operating systems, and potential post-closing claims for indemnification or breach of transition services obligations of the seller. Expected cost savings, which are offset by revenue losses from divested businesses, may also be difficult to achieve or maximize due to the seller’s fixed cost structure, and a seller may experience varying success in reducing fixed costs or transferring liabilities previously associated with the divested business.
