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 mixed signal semiconductor solutions for the communications and computing markets. The Company’s end-to-end data transport platform delivers high signal at leading – edge data speeds, addressing performance and bandwidth bottlenecks in networks, from fiber to memory. The Company’s semiconductor solutions minimize latency in computing environments and enable the rollout of next generation communications and computing infrastructures. The Company’s 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, datacenter and enterprise servers and storage platforms.

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, 2011, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 15, 2012.

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, 2012, and its consolidated results of operations for the three and six months ended June 30, 2012 and 2011 and cash flows for the six months ended June 30, 2012 and 2011. The results of operations for the three and six months ended June 30, 2012 are not necessarily indicative of the results to be expected for future quarters or the full year.

2. Recent Accounting Pronouncements

In May 2011, Financial Accounting Standards Board (“FASB”) issued an amendment to its accounting guidance on fair value measurement. The amendments provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between GAAP and International Financial Reporting Standards. The amendments change certain fair value measurement principles and enhance the disclosure requirements about fair value measurements. This guidance is effective during interim and annual periods beginning after December 15, 2011 and are applied prospectively. The adoption of this guidance had no impact on the Company’s consolidated financial statements.

In June 2011, FASB issued an amendment to its accounting guidance on comprehensive income. The amendments require an entity to present the total of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendments eliminate the option to present the components of other comprehensive income as part of the statement of equity. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The Company has elected to present the components of comprehensive income as a separate statement. In December 2011, the FASB issued amendments to defer the presentation on the face of the financial statements the reclassification adjustments out of accumulated other comprehensive income on the components of net income and other comprehensive income for all periods presented.

3. Investments

The following table summarizes the investments by investment category:

	June 30, 2012				December 31, 2011
	Cost		Fair Value		Cost		Fair Value
Available-for-sale securities:
US treasury securities	$	23,549	$	23,547	$	24,153	$	24,156
Municipal bonds		38,062		38,332		40,080		40,272

Total investments	$	89,776	$	90,053	$	89,377	$	89,283

As of June 30, 2012, we had 25 investments that were in an unrealized loss position. The gross unrealized losses on these investments at June 30, 2012 of $66 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 contractual maturities of available-for-sale securities at June 30, 2012 are presented in the following table:

	Cost		Fair Value
Due in one year or less	$	38,033	$	38,067
Due between one and five years		51,743		51,986
	$	89,776	$	90,053

4. Inventories

Inventories consist of the following:

	June 30, 2012		December 31, 2011

As of June 30, 2012 and December 31, 2011, computer software costs included in property and equipment were $1,999 and $1,712, respectively. Amortization expense of capitalized computer software costs was $66 and $127 for the three and six months ended June 30, 2012, respectively. Amortization expense of capitalized computer software costs was $58 and $113 for the three and six months ended June 30, 2011, respectively.

6. Product Warranty Obligation

As of June 30, 2012 and December 31, 2011, the product warranty liability was $1,750 and $1,000, respectively. The following table sets forth changes in warranty accrual included in other accrued expenses in the Company’s consolidated balance sheets:

	Three Months Ended June  30,				Six Months Ended June 30,
	2012		2011		2012		2011
Beginning balance	$	1,750	$	615	$	1,000	$	602
Accruals for warranties		—		385		750		398
Settlements		—		—		—		—
	$	1,750	$	1,000	$	1,750	$	1,000

In September 2010, the Company was informed of a claim related to repair and replacement costs in connection with shipments of over 4,000 integrated circuits made by the Company during the summer and fall of 2009. The Company also began to assess, provide and accumulate additional warranty reserves based on estimated, probable costs to replace units.

In March 2010, the Company developed additional tests to screen out the wafer die that might be susceptible to a suspected type of failure ultimately related to the lack of a manufacturing design rule and resumed shipments to the customer. Based on its standard warranty provisions, the Company has provided replacement parts to the customer for the known and suspected failures that had occurred.

In 2012, based on additional review, investigation and discussions with the customer, the Company booked an additional warranty accrual of $750. This amount was recorded as a reduction to revenue. In June 2012, the Company entered into a settlement agreement with the customer in which the Company paid $1,750 cash in July 2012 to settle this claim.

7. Other long-term liabilities

Other long-term liabilities consist of the following:

	June 30, 2012		December 31, 2011
Deferred rent	$	1,603	$	1,988
Income tax payable		1,903		1,546
	$	3,506	$	3,534

8. Income Taxes

The Company normally determines its interim tax provision using an estimated annual effective tax rate methodology. For the three and six months ended June 30, 2012, the discrete method was used to calculate the Company’s interim tax expense. The Company has determined that a calculation of an annual effective tax rate would not represent a reliable estimate due to the sensitivity of the annual effective tax rate estimate to even minimal changes to forecasted earnings for the year. Under the discrete method, the Company determines its tax expense based upon actual results as if the interim period were an annual period.

The Company recorded an income tax provision (benefit) of $346 and ($924) in the three and six months ended June 30, 2012, respectively. During the three and six months ended June 30, 2011, the Company recorded an income tax provision of $383 and $1,149, respectively. The effective tax rate for the three and six months ended June 30, 2012 was (28%) and 23%, respectively from 14% and 19% in the comparable periods of 2011, respectively. The difference between the effective tax rates and the 35% federal statutory rate resulted primarily from foreign income taxes provided at lower rates, geographic mix in operating results, recognition of research and development credits, unrecognized tax benefits and stock-based compensation adjustments.

During the three and six months ended June 30, 2012, the gross amount of the Company’s unrecognized tax benefits increased approximately $2,032 and $647, respectively as a result of tax positions taken during the current year. Substantially all of the unrecognized tax benefits as of June 30, 2012, if recognized, would affect the Company’s effective tax rate. As of June 30, 2012, the Company does not expect any significant increases or decreases to its unrecognized tax benefits within the next 12 months.

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.

Net income (loss) has been allocated to the common stock, unvested early exercised options and unvested restricted stock awards based on their respective rights to share in dividends.

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,

		6,494,226		1,179,193		6,305,992		594,605

10. Stock–Based Compensation

In 2000, the Company adopted the 2000 Stock Option/Stock Issuance Plan (the “2000 Plan”). Under the provisions of the 2000 Plan, employees, outside directors, consultants and other independent advisors who provide services to the Company may be issued incentive and non-qualified stock options to purchase common stock or may be issued shares of common stock directly. The Board of Directors is authorized to administer the 2000 Plan and establish the stock option terms, including the exercise price and vesting period. Options granted under the plan may have varying vesting schedules; however, options generally vest 25% upon completion of one year of service and thereafter in 36 equal monthly installments. Options granted are immediately exercisable and the shares issued upon exercise of the option are subject to a repurchase right held by the Company. The repurchase price under the repurchase right is the original exercise price and the right lapses in accordance with the option-vesting schedule. As of June 30, 2012 and December 31, 2011, there were no unvested shares outstanding subject to the Company’s right of repurchase. The proceeds received from the unvested early exercise of options are presented in the balance sheet as liabilities and subsequently classified to equity based on the vesting schedule. The vesting of certain options granted or shares issued under the 2000 Plan is subject to acceleration of vesting upon the occurrence of certain events as defined in the 2000 Plan.

Under the 2000 Plan, the exercise price, in the case of an incentive stock option, can-not be less than 100%, and in the case of a nonqualified stock option, not less than 85%, of the fair market value of such shares on the date of grant. The term of the option is determined by the Board but in no case can exceed 10 years.

In June 2010, the Board of Directors approved the Company’s 2010 Stock Incentive Plan (the “2010 Plan”), which became effective in November 2010. Upon completion of the Company’s initial public offering, shares originally reserved for issuance under the 2000 Plan but which were not issued or subject to outstanding grants on the effective date of the 2010 Plan, and shares subject to outstanding options or forfeiture restriction under the 2000 Plan on the effective date of the 2010 Plan that are subsequently forfeited or terminated before being exercised, become available for awards under the 2010 Plan, up to 428,571 shares. 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 Board of Directors 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, 2012, 1,717,268 shares of common stock have been reserved for future grants under the 2010 Plan.

Stock Option Awards

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions:

	Three Months Ended June  30,						Six Months Ended June  30,
	2012			2011			2012			2011
Risk-free interest rate		1.43	%		2.84	%		1.39	%		2.84	%
Expected life (in years)		6.25			6.46			6.25			6.45
Dividend yield		—			—			—			—
Expected volatility		50.00	%		50.00	%		50.00	%		50.00	%

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, 2011		4,259,106		$	7.50		7.21	$	25,168
Granted		1,295,995			13.55
Exercised		(450,558	)		2.57
Canceled		(275,350	)		13.15
Outstanding at June 30, 2012		4,829,193		$	9.26		6.85	$	14,111
Exercisable at June 30, 2012		2,896,132		$	4.87		5.25	$	14,111
Vested at June 30, 2012		2,241,180		$	3.88		4.60	$	13,486
Vested and expected to vest at June 30, 2012		4,753,485		$	9.18		6.81	$	14,102

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 grant date fair value of employee options vested during the six months ended June 30, 2012 and 2011 was $1,800 and $1,597, respectively.

The weighted average grant date fair value per share of stock options granted to employees during the six months ended June 30, 2012 and 2011 was $6.65 and $11.48, respectively.

The total intrinsic value of options exercised during the six months ended June 30, 2012 and 2011 was $5,173 and $39,271, 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 $1,156 and $3,280, respectively, for the six months ended June 30, 2012 and 2011.

Restricted Stock Units and Awards

The Company granted restricted stock units and awards to members of the Board of Directors and employees. Most of the Company’s outstanding restricted stock units vest over four years with vesting contingent upon continuous service. The Company estimates the fair value of restricted stock units and awards 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, 2011		726,556		$	20.58
Granted		1,057,586			12.96
Vested		(79,188	)		19.36
Canceled		(81,667	)		18.59
Outstanding at June 30, 2012		1,623,287			15.77
Expected to vest at June 30, 2012		1,563,985

As of December 31, 2011, the Company had 21,425 outstanding nonvested restricted stock awards, 4,288 of which vested during the six months ended June 30, 2012 resulting to 17,137 nonvested restricted stock awards outstanding as of June 30, 2012.

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 shares at the beginning or the end of each six-month period.

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 to 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 one million shares. There was no common stock issued under the ESPP during the six months ended June 30, 2012 as the first offering period under the ESPP commenced in February 2012.

The fair value of employee stock purchase plan is estimated at the start of offering period using the Black-Scholes option pricing model with the following assumptions for the six months ended June 30, 2012:

Risk-free interest rate		0.12	%
Expected life (in years)		0.50
Dividend yield		—
Expected volatility		90	%
Estimated fair value	$	5.90

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,
	2012		2011		2012		2011
Operating expenses
Cost of goods sold	$	190	$	119	$	319	$	160

Sales and marketing		840		660		1,544		798
General and administrative		800		470		1,418		640
	$	3,311	$	2,315	$	5,928	$	2,943

Total unrecognized compensation cost related to unvested stock options, restricted stock units and awards at June 30, 2012, prior to the consideration of expected forfeitures, is approximately $36,525 and is expected to be recognized over a weighted-average period of 3.13 years.

11. 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, 2012.

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

June 30, 2012	Total		Level 1		Level 2

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 Company’s 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, Company filedinter partes requests for reexamination with the United States Patent and Trademark Office (the “USPTO”), asserting that the patents-in-suit are invalid.

On August 27, 2010, the USPTO ordered the request forInter Partes Reexamination for U.S. Patent No. 7,636,274 and found a substantial new question of patentability based upon each of the different issues that the Company raised as the reexamination requestor. On September 27, 2011, the Patent Office issued a First Office Action based on the Netlist ‘274 Patent Reexamination Request and rejected 91 of its 97 claims. On October 27, 2011, Netlist responded to the USPTO determination by amending some but not all of the claims, adding new claims and making arguments as to the validity of the rejected claims in view of the cited references. The Company provided rebuttable comments to the USPTO on November 28, 2011. On March 12, 2012, the Examiner issued an Action Closing Prosecution, indicating that the claims pending contain allowable subject matter, and Netlist did not respond to the Action Closing Prosecution in the time provided by the USPTO. On June 22, 2012, the USPTO issued a Right of Appeal Notice, and on July 23, 2012, the Company filed a Notice of Appeal. Netlist has an opportunity to cross-appeal, pending which the Company expect to file an Appeal Brief. The proceeding is expected to continue in accordance with establishedInter Partes Reexamination procedures.

On September 8, 2010, the USPTO ordered the request forInter Partes Reexamination for U.S. Patent No. 7,532,537 and found a substantial new question of patentability based upon different issues that the Company raised as the reexamination requestor. The USPTO accompanied this Reexamination Order of U.S. Patent No. 7,532,537 with its own evaluation of the validity of this patent, and rejected some but not all of claims. In a response dated October 8, 2010, Netlist responded to the USPTO determination by amending some but not all of the claims, adding new claims and making arguments as to why the claims were not invalid in view of the cited references. The Company provided rebuttable comments to the USPTO on November 8, 2010 along with a Petition requesting an increase in the number of allowed pages of the rebuttable comments. On January 20, 2011, the USPTO granted the Petition in part. The Company then filed updated rebuttal comments on January 27, 2011 in compliance with the granted Petition. The USPTO has considered these updated rebuttal comments, and in a communication dated June 15, 2011, continued to reject all the previously rejected claims. The USPTO also rejected all the claims newly added in the October 8, 2010 Netlist response. In a further communication dated June 21, 2011, the USPTO issued an Action Closing Prosecution indicating that it would confirm the patentability of four claims and reject all the other pending claims. On August 22, 2011, Netlist responded to the Action Closing Prosecution by further amending some claims and making arguments as to the validity of the rejected claims in view of the cited references. The Company submitted rebuttal comments on September 21, 2011. In a further communication dated February 7, 2012, the USPTO issued a Right of Appeal Notice, which also indicated that the previous amendments to claim made by Netlist would be entered, and that the current pending claims, as amended, were patentable. The Company filed a Notice of Appeal at the USPTO on March 8, 2012, within the time period provided for filing the Notice of Appeal and Netlist did not file Notice of Cross-Appeal. The Company filed its Appeal Brief on May 8, 2012, and Netlist filed its Responsive Brief on July 2, 2012. The parties are awaiting a further communication from the USPTO as the next substantive step of the proceeding. The proceeding is expected to continue in accordance with establishedInter Partes Reexamination procedures.

On September 8, 2010, the USPTO ordered the request forInter Partes Reexamination for U.S. Patent No. 7,619,912 and found a substantial new question of patentability based upon different issues that the Company raised as the reexamination requestor. The USPTO accompanied this Reexamination Order of U.S. Patent No. 7,619,912 with its own evaluation of the validity of this patent, and initially determined that all of the claims were patentable based upon the Company’s request forInter Partes Reexamination. Netlist did not comment upon this Reexamination Order. The USPTO on February 28, 2011 also merged the Proceedings of the Company’s Reexamination of U.S. Patent No. 7,619,912, bearing Control No. 90/001,339 with Inter Partes Reexamination Proceeding 95/000,578 filed October 20, 2010 on behalf of SMART Modular Technologies, Inc. and Inter Partes Reexamination Proceeding 95/000,579 filed October 21, 2010 on behalf of Google, Inc. In each of these other Reexamination Proceedings, the USPTO had indicated that there existed a substantial new question of patentability with respect to certain claims of U.S. Patent No. 7,619,912, but had not accompanied the Reexamination Orders related thereto with its own evaluation of the validity of this patent, indicating that such evaluation would be forthcoming at a later time. This further evaluation was received in an Office Action dated April 4, 2011, in which the Examiner rejected a substantial majority of the claims based upon a number of different rejections, including certain of the rejections originally proposed by the Company in its Request for Reexamination. This Office Action also indicated that one claim was deemed to be patentable over the prior art of record in the merged Reexamination Proceedings. After seeking and obtaining an extension of time to respond to the Office Action dated April 4, 2011, Netlist served its response on July 5, 2011, which added new claims and made arguments as to why the originally filed claims were not invalid in view of the cited references. Each of the merged Reexamination Requestors, including the Company, submitted rebuttal comments by August 29, 2011. The USPTO considered this Netlist response and each of the rebuttal comments, and in an Office Action dated October 14, 2011, continued to reject most, but not all of the previously rejected claims, as well as rejected claims that had been added by Netlist in its July 5, 2011 response. After seeking and obtaining an extension of time to respond to the Office Action dated October 14, 2011, Netlist served its response on January 13, 2012, which response made amendments based upon subject matter that had been indicated as allowable in the Office Action dated October 14, 2011, added other new claims and made arguments as to why all of these claims should be allowed. The three different merged Reexamination Requestors, including the Company, timely submitted rebuttal comments on or about February 13, 2012. The merged Reexamination Proceeding will be conducted in accordance with established procedures for merged Reexamination Proceedings, with a further communication from the USPTO expected as the next substantive step.

The reexamination proceedings could result in a determination that the patents-in-suit, in whole or in part, are valid or invalid, as well as modifications of the scope of the patents-in-suit.

Based on these papers the court in January 2012 ordered a continued stay of the proceedings until the conclusion of the reexamination and interference proceedings, and in the meantime requested that the parties file papers by January 30, 2013 stating their position on whether the stay should be extended. At this time, the Court could decide to maintain or lift the stay.

On March 29, 2012, the Company received notice of a lawsuit, entitled Claim for Confirmation of Invalidation of Dismissal etc., filed in an international jurisdiction by a former employee. The Company was subsequently served with the complaint in April 2012. Legal and other expenses and accrual of costs related to this and other matters are reflected in the Company’s financial statements as of June 30, 2012. The lawsuit was withdrawn in June 2012 and the claim was settled in July 2012.

While the Company intends to defend the foregoing lawsuits vigorously, 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.

The Company is unable to assess the possible outcome of these matters. 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.

• Total revenues decreased by $0.7 million, or 3%, to $23.3 million in the three months ended June 30, 2012. In the six months ended June 30, 2012, total revenues decreased by $2.0 million, or 4%, to $43.5 million.

• Gross profit as a percentage of revenue decreased to 64.3% from 64.8% in the three months ended June 30, 2012. In the six months ended June 30, 2012, gross profit as a percentage of revenue decreased to 63.8% from 65.2%.

• Total operating expenses increased by $3.6 million, or 28%, to $16.4 million in the three months ended June 30, 2012. In the six months ended June 30, 2012, total operating expenses increased by $8.4 million, or 35%, to $32.2 million.

• Income from operations decreased by $4.2 million, or 152%, to a loss from operations of $1.4 million in the three months ended June 30, 2012. In the six months ended June 30, 2012, income from operations decreased by $10.3 million, or 176%, to a loss from operations of $4.5 million.

• Diluted earnings per share decreased by $0.14 to ($0.06) in the three months ended June 30, 2012. In the six months ended June 30, 2012, diluted earnings per share decreased by $0.27 to ($0.11).

This decrease in our revenue was a result of discontinuance of legacy products supported by our Taiwan subsidiary and provision for estimated settlement of a warranty claim with a customer that was several years old.

Our income from operations decreased due to lower gross profit and increased operating expenses. 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 2011 to June 2012, we hired 46 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 decreased primarily due to reduction in revenues combined with increases in operating expenses.

Our cash and cash equivalents were $33.8 million at June 30, 2012, compared with $29.7 million at December 31, 2011. We generated cash flow from operations of $8.1 million during the six months ended June 30, 2012 compared to $2.4 million during the six months ended June 30, 2011. Cash used in investing activities during the six months ended June 30, 2012 was $5.0 million primarily due to purchases of marketable securities and purchases of property and equipment offset by sales and maturities of marketable securities. We generated cash flow from financing activities of $1.0 million primarily due to proceeds from exercise of stock options of $1.2 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 valuation, deferred income tax asset valuation allowances, uncertain tax positions, litigation and other loss contingencies. 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, 2011. There have been no material changes in any of our critical accounting policies during the six months ended June 30, 2012.

	2012		2011		Amount			%
	(dollars in thousands)
Total revenue	$	43,509	$	45,505	$	(1,996	)		(4	)%

Total revenue for three and six months ended June 30, 2012 decreased compared to corresponding 2011 periods due to decrease in the number of units sold of 44% and 36%, respectively. This decrease was due to discontinuance of legacy products supported by our Taiwan subsidiary. In addition, revenue for the six months ended June 30, 2012 decreased by $0.8 million for estimated settlement of a warranty claim with a customer that was several years old. The decreases were partially offset by a year over year increase in average selling price of approximately 73% and 51% for three and six months ended June 30, 2012, respectively. The increase in average selling price was due to change in product mix, mainly as a result of the discontinuance of storage products sold at lower prices.

	2012		2011		Amount		%
	(dollars in thousands)
Research and development	$	18,572	$	13,661	$	4,911		36	%

Research and development expenses for three and six months ended June 30, 2012 increased due to the increase in research and development headcount and equity awards, which resulted in $1.2 million and $2.8 million increase in personnel costs and stock-based compensation expense, respectively. In addition, packaging and pre-production engineering mask costs increased by $0.8 million and $0.7 million, and consulting fees increased by $0.8 million and $1.0 million for the three and six months ended June 30, 2012, respectively. The increase in research and development expense was primarily driven by our strategy to expand our product offerings and enhance our existing products. Specifically, we accelerated the development of our products for next generation communications networks and high-speed memory interfaces.

Sales and Marketing

	Three Months Ended June 30,				Change
	2012		2011		Amount		%

Sales and marketing	$	7,268	$	5,719	$	1,549		27	%

Sales and marketing expenses for three and six months ended June 30, 2012 increased primarily due to an increase in personnel costs, including stock-based compensation expense of $0.2 million and $1.1 million, respectively, to support sales activities.

General and Administrative

	Three Months Ended June 30,				Change
	2012		2011		Amount		%

General and administrative	$	6,367	$	4,419	$	1,948		44	%

General and administrative expenses for the three and six months ended June 30, 2012 increased primarily due to increase in personnel costs and legal fees. Personnel costs, including stock-based compensation expense increased by $0.3 million and $0.8 million for the three and six months ended June 30, 2012, respectively, due to an increase in headcount and equity awards. Outside legal fees increased by $0.2 million and $0.5 million for the three and six months ended June 30, 2011, respectively, related primarily to litigation matters described in note 13 of the notes to our consolidated financial statements. In addition, we recorded an accrual of costs with regard to employment and other related claims as well as associated costs of $0.7 million during the six months ended June 30, 2012.

Provision (benefit) for Income Taxes

	Three Months Ended June 30,				Change

	(dollars in thousands)
Provision (benefit) for income taxes	$	(924	)	$	1,149	$	(2,073	)		(180	)%

The income tax expense for the three and six months ended June 30, 2012 reflects an effective tax rate of (28%) and 23%, respectively. The effective tax rates for the three and six months ended June 30, 2012 differs from the statutory rate of 35% primarily due to foreign income taxes provided at lower rates, geographic mix in profitability, recognition of research and development credits, and unrecognized tax benefits. For the three and six months ended June 30, 2012, the discrete method was used to calculate the interim tax expense. We determined that a calculation of an annual effective tax rate would not represent a reliable estimate due to the sensitivity of the annual effective tax rate estimate to even minimal changes to forecasted earnings for the year. Under the discrete method, we determine the tax expense based upon actual results as if the interim period were an annual period.

The income tax expense for the three and six months ended June 30, 2011 reflects an effective tax rate of 14% and 19%, respectively. The effective tax rates for the three and six months ended June 30, 2011 differs from the statutory rate of 35% primarily due to foreign income taxes provided at lower rates, geographic mix in profitability, recognition of research and development credits, and unrecognized tax benefits.

Liquidity and Capital Resources

As of June 30, 2012, we had cash, cash equivalents and investments in marketable securities of $123.8 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. 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,
	2012			2011
	(in thousands)
Net cash provided by operating activities	$	8,089		$	2,407
Net cash used in investing activities		(4,974	)		(89,590	)

Effect of currency exchange rate on cash		—			(1	)
Net increase (decrease) in cash and cash equivalents	$	4,067		$	(77,610	)

Net Cash Provided by Operating Activities

Net cash provided by operating activities during the six months ended June 30, 2012 primarily reflected an increase in accounts payable and accrued expenses of $3.7 million, an increase in deferred revenue of $0.9 million, decrease in inventory of $0.8 million, depreciation and amortization of $2.0 million and stock-based compensation of $5.9 million offset by net loss of $3.1 million and increases in accounts receivable of $1.7 million and change in income tax payable/receivable of $0.6 million . Our accounts payable and accrued expenses increased as a result of increased production volume, provision for warranty costs, employment and other related claims. Our receivables increased due to shipments made in the last month of the quarter. Our deferred revenue increased as distributors increased their inventory level for shipment to customers in third quarter. Our inventory decreased due to shipments to customers in the last month of the quarter.

Net cash provided by operating activities for the six months ended June 30, 2011 primarily reflected net income of $4.8 million, change in income tax payable/receivable of $1.9 million, increase in accrued expenses of $2.0 million, depreciation and amortization of $1.6 million and stock-based compensation of $2.9 million, offset by increases to accounts receivable of $0.8 million and inventories of $1.2 million, decreases to accounts payable of $0.7 million and deferred revenue of $0.6 million, deferred income taxes of $0.8 million and excess tax benefit related to stock-based compensation of $6.1 million. Accrued expenses increased as a result of inventories received not yet invoiced by the vendors. Our accounts receivable increased due to higher product shipments in the second quarter of 2011. Our inventories increased as a result of growing production for expected delivery to customers in the third quarter of 2011. Our accounts payable decreased due to payments to vendors. Our deferred revenue decreased as distributors reduced their inventory levels and shipped parts to end customers to meet their demand.

Net Cash Used in Investing Activities

Net cash used in investing activities during the six months ended June 30, 2012, consisted of cash used to purchase property and equipment of $4.3 million and purchases of marketable securities of $18.6 million, offset by sales and maturities of marketable securities of $17.7 million

During the six months ended June 30, 2011, net cash used in investing activities consisted of cash used to purchase investments in marketable securities of $87 million and property and equipment of $2.6 million mainly for laboratory equipment and leasehold improvements for our offices in California.

Net Cash Provided by Financing Activities

Net cash provided by financing activities during the six months ended June 30, 2012 consisted primarily of proceeds from exercise of stock options of $1.2 million.

Net cash provided by financing activities during the six months ended June 30, 2011 consisted primarily of $6.1 million excess tax benefit related to stock-based compensation, net proceeds from secondary offering of $1.3 million and proceeds from the exercise of stock options and warrants of $3.3 million. In addition, we also paid $1.1 million of expenses related to our initial public offering.

Operating and Capital Expenditure Requirements

Our principal source of liquidity as of June 30, 2012 consisted of $123.8 million of cash, cash equivalents and investments in marketable securities, of which $4.9 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 to 18 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

23

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.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Sensitivity

We had cash and cash equivalents and investments in marketable securities of $123.8 million and $119.0 million at June 30, 2012 and December 31, 2011, 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, 2012 consisted of money market funds, U.S. Treasuries, municipal bonds, corporate bonds, certificates of deposit, 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.

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 do not currently enter into foreign currency hedging transactions.

24

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 and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any 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 met. Our disclosure controls and procedures have been designed to meet reasonable assurance standards. 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 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.

Based on their evaluation as of the end of the period covered by this Quarterly Report on Form 10-Q, our Chief Executive Officer and Chief 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 during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
