NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The condensed consolidated financial statements include all the accounts of Applied Micro Circuits Corporation (“AMCC”, “APM”, “AppliedMicro” or the “Company”), and its wholly-owned subsidiaries including Veloce Technologies Inc. (“Veloce”), which was consolidated in prior accounting periods as a variable interest entity (“VIE”) since the Company was determined to be its primary beneficiary. On June 20, 2012, the Company completed the acquisition of Veloce which became a wholly owned subsidiary of the Company as of this date. See note 4 of Notes to Condensed Consolidated Financial Statements. All significant intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management 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. The Company regularly evaluates estimates and assumptions related to its:

• capitalized mask sets including its useful lives, which affects cost of goods sold and property and equipment or R&D expenses, if not capitalized;

• inventory valuation, warranty liabilities, and revenue reserves, which affects cost of sales, gross margin, and revenues;

• allowance for doubtful accounts, which affects operating expenses;

• the unrealized losses or other-than-temporary impairments of short-term investments available for sale, which affects interest income (expense), net;

• the valuation of purchased intangibles and goodwill, which affects amortization and impairments of purchased intangibles and impairments of goodwill;

• Veloce accrued liability which considers: (i) estimating the total value of the expected Veloce consideration, (ii) determining the stage at which a milestone is deemed to be probable of attainment, (iii) the estimated progress towards achieving the milestone at the time such milestone was deemed probable of achievement, and (iv) estimating the approximate timing of the expected completion of the milestones and related payments;

• the potential costs of litigation, which affects operating expenses;

• the valuation of deferred income taxes, which affects income tax expense (benefit); and

• stock-based compensation, which affects gross margin and operating expenses.

The Company bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. The actual results experienced by the Company may differ materially and adversely from management’s estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected.

Strategic Investments

The Company has entered into certain equity investments in privately held businesses to achieve certain strategic business objectives. The Company’s investments in equity securities of privately held businesses are accounted for under the cost method. Under the cost method, strategic investments in which the Company holds less than a 20% voting interest and on which the Company does not have the ability to exercise significant influence are carried at the lower of cost or cost reduced by other-than-temporary impairments, as appropriate. These investments are included in other assets on the Company’s condensed consolidated balance sheets. The Company periodically reviews these investments for other-than-temporary declines in fair value based on the specific identification method and writes down investments when an other-than-temporary decline has occurred. No other-than-temporary declines were recorded during the three and nine months ended December 31, 2012 and 2011. During the three and nine months ended December 31, 2012 and 2011, the Company invested zero and $0.5 million, and $2.25 million and $4.75 million, respectively, in non-marketable equity investments and these amounts were carried at cost.

* At December 31, 2012 and March 31, 2012, approximately $1.7 million and $4.6 million of the estimated fair value presented were mortgage-backed securities, respectively.

The established guidelines for measuring fair value and expanded disclosures regarding fair value measurements are defined as a three-level valuation hierarchy for disclosure of fair value measurements as follows:

Level 1 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2 — Inputs (other than quoted market prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.

Level 3 — Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Valuation of instruments includes unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of assets or liabilities.

The following is a summary of cash, cash equivalents and available-for-sale investments by type of instruments measured at fair value on a recurring basis (in thousands):

Other-Than-Temporary Impairment

Based on an evaluation of securities that have been in a loss position, the Company did not recognize any other-than-temporary impairment charges, for the three and nine months ended December 31, 2012 and 2011. The Company considered various factors which included a credit and liquidity assessment of the underlying securities and the Company’s intent and ability to hold the underlying securities until its estimated recovery of amortized cost. As of December 31, 2012 and March 31, 2012, the Company also had $7.3 million and $7.5 million in gross unrealized gains, respectively. The basis for computing realized gains or losses is by specific identification.

Warranty reserves:

The Company’s products typically carry a one year warranty. The Company establishes reserves for estimated product warranty costs at the time revenue is recognized. Although the Company engages in extensive product quality programs and processes, its warranty obligation is affected by product failure rates, use of materials and service delivery costs incurred in correcting any product failure. Should actual product failure rates, use of materials or service delivery costs differ from the Company’s estimates, additional warranty reserves could be required, which could reduce its gross margin.

Net loss per share:

Shares used in basic net loss per share are computed using the weighted average number of common shares outstanding during each period. Shares used in diluted net loss per share include the dilutive effect of common shares potentially issuable upon the exercise of stock options, vesting of restricted stock units (“RSUs”) and outstanding warrants. However, potentially issuable common shares are not used in computing diluted net loss per share as their effect would be anti-dilutive due to the loss recorded during the periods presented. The reconciliation of shares used to calculate basic and diluted net loss per share consists of the following (in thousands, except per share data):

	Three Months Ended						Nine Months Ended
	December 31,						December 31,
	2012			2011			2012			2011
Net loss	$	(71,562	)	$	(7,077	)	$	(116,509	)	$	(15,106	)
Shares used in net loss per share computation:

Basic and diluted net loss per share	$	(1.08	)	$	(0.12	)	$	(1.81	)	$	(0.24	)

The effect of anti-dilutive securities (comprised of options and restricted stock units) totaling 5.4 million and 8.7 million equivalent shares for the three and nine months ended December 31, 2012, respectively, and 10.7 million and 8.8 million shares for the three and nine months ended December 31, 2011, respectively, have been excluded from the net loss per share computation, as their impact would be anti-dilutive because the Company has incurred losses in the periods presented.

12

The effect of dilutive securities (comprised of options and restricted stock units) totaling 1.4 million and 0.7 million equivalent shares for the three and nine months ended December 31, 2012, respectively, and 0.2 million and 0.5 million shares for the three and nine months ended December 31, 2011, respectively, have been excluded from the net loss per share computation, as their impact would be anti-dilutive because the Company has incurred losses in the periods presented.

Total equivalent shares excluded from the net loss per share computation are 6.8 million and 9.4 million for the three and nine months ended December 31, 2012, respectively, and 10.9 million and 9.3 million shares for three and nine months ended December 31, 2011, respectively.

3. RESTRUCTURING CHARGES

The Company recognizes restructuring costs related to asset impairment and exit or disposal activities. Cost relating to facilities closure, or lease commitments are recognized when the facility has been exited. Termination costs are recognized when the cost are deemed both probable and estimable.

December 2012 Restructuring Program

The Company implemented a restructuring program during the three months ended December 31, 2012to reorganize its' operations and reduce its workforce and related operating expenses. The plan includes eliminating job redundancies and reducing the Company's current workforce by approximately 70 employees. As a result, the Company recorded a charge of $1.5 million for employee severances and $4.7 million for an asset impairment. The asset impairment related to the impairment of the unamortized value of a software intellectual property license, which the Company no longer intends to use to develop new products. The Company expects the restructuring program to be completed by the end of its current fiscal year ended March 31, 2013.

The restructuring activity for the three months ended December 31, 2012 is described below.

	Workforce Reduction			Asset Impairment		Total
Restructuring charges	$	1,529		$	4,689	$	6,218
Cash payments	(97		)	—		(97		)
Liability	$	1,432		$	4,689	$	6,121

April 2011 Restructuring Program

The April 2011 restructuring program was implemented as part of the Company’s ongoing cost reduction efforts and to better align its global operations to achieve greater efficiencies. The Company moved more of its functions offshore, which would allow it to be closer and more connected to its customer’s third party subcontract manufacturers. The April 2011 restructuring plan included eliminating or relocating 25 positions. As a result of the April 2011 restructuring program, the Company recorded a charge of $0.9 million for employee severances for the three and nine months ended December 31, 2011.

4. VELOCE

On June 20, 2012 (the “Closing Date”), the Company completed its acquisition of Veloce pursuant to the terms of the Agreement and Plan of Merger, entered into as of May 17, 2009 (the “Initial Agreement”), as amended by Amendment No. 1 to Agreement and Plan of Merger, entered into as of November 8, 2010 (the “First Amendment”), and Amendment No. 2 to Agreement and Plan of Merger, entered into as of April 5, 2012 (the “Second Amendment” and, collectively with the Initial Agreement and the First Amendment, the “Merger Agreement”). The First Amendment was amended, restated and replaced in its entirety by the Second Amendment.

The terms of the Merger Agreement include the payment of initial consideration of up to $60.4 million, payable in shares of Company common stock and/or cash (at the Company's election) to holders of Veloce common stock, Veloce stock options that were vested on the Closing Date, and holders of Veloce stock equivalents (collectively, “Veloce Equity Holders”). During the three and nine months ended December 31, 2012, as part of the above arrangement, the Company issued 0.2 million shares valued at $1.1 million and 2.9 million shares valued at $16.0 million, respectively, and paid approximately $1.1 million and $15.9 million in cash, respectively. Of the $60.4 million that relates to the initial consideration, $31.9 million has been paid to date. To the extent payments of the $60.4 million are paid in the Company's common stock and relate to shares of Veloce stock that were outstanding at the date of the closing of the Merger, the value of the Company's common stock is fixed at $5.546 per share (“fixed shares”). The balance of the $60.4 million or approximately $28.5 million will be paid over multiple quarters and will include approximately 1.2 million fixed shares and at least $10.2 million in cash for a total value of $16.9 million.

13

The remaining $11.6 million of the $28.5 million will be paid in a combination of cash and shares of the Company's common stock valued at the then-current market price.

For accounting purposes, the consideration to be paid under the Merger Agreement is considered compensatory and is recognized as research and development expense when incurred. Recognition of these costs as expense will occur when the specific development and performance milestones become probable of achievement and the amount of expense will be based upon the estimated stage of product development to date. As of March 31, 2012, the first development and performance milestone set forth under the Merger Agreement was considered probable of achievement and the Company recognized $60.4 million of research and development expense.

The total estimated value to the Veloce Equity Holders is based on the Company achieving certain performance benchmarks defined under the Merger Agreement within a certain time period. The Company performed various simulations during the three months ended December 31, 2012. The results of the simulations exceeded expectations for certain of the benchmarks defined under the Merger Agreement, and as a result the estimated maximum value to the Veloce Equity Holders was increased from approximately $135 million to the contractual maximum of $178.5 million, based on the Company's current expectations regarding the achievement of such product development milestones. As such, the total expense that the company expects to recognize has been updated to be in the range of $117M (recognized through December 31, 2012) up to $178.5 million, depending upon the achievement of multiple product development cycles and technical performance results. The increase in the estimated value to the Veloce Equity Holders also resulted in an increase of the estimated value of the first performance milestone. Research and Development expense recognized during the three months ended December 31, 2012 relating to the first performance milestone was based upon the estimated stage of the development of the first milestone as of December 31, 2012 and the estimated value tied to the first performance milestone. The remaining costs associated with the first performance milestone, estimated value of the first milestone less expense recognized through December 31, 2012, will be recognized on a straight line basis, subject to adjustment for actual progress towards the milestones, over the remaining period of expected development which is currently estimated not to exceed the next three fiscal quarters.

Additionally, during the three months ended December 31, 2012, the second development and performance milestone set forth under the Merger Agreement was considered probable of achievement. The Company recognized research and development expenses that were based upon the estimated stage of development and estimated value tied to the second performance milestone. The remaining costs associated with the second performance milestone will be recognized on a straight line basis, subject to adjustment for actual progress towards the milestones, over the remaining period of expected development which is currently estimated not to exceed the next three fiscal quarters.

The third and last development and performance milestone set forth under the Merger Agreement was not yet considered probable of achievement as of December 31, 2012.

Total research and development expenses expected to be recognized upon completion of the first and second performance milestones is approximately $142.8 million (including the initial consideration of $60.4 million), of which approximately $117 million has been recognized through December 31, 2012. During the three and nine months ended December 31, 2012, expenses recognized in connection with first and second performance milestones were $51.9 million and $56.6 million, respectively. The amount and timing of expense recognition is determined based upon the probability of the respective performance milestone being achieved, the estimated progress of development, and estimated date of the milestone attainment. Timing of payments will be based upon actual attainment of the development and performance milestones, and upon vesting, if any, associated with outstanding Veloce' stock equivalents.

5. STOCKHOLDERS’ EQUITY

Preferred Stock

The Certificate of Incorporation allows for the issuance of up to two million shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences, and the number of shares constituting any series of the designation of such series, without further vote or action by the stockholders.

Common Stock

At December 31, 2012, the Company had 375.0 million shares authorized for issuance and approximately 67.0 million shares issued and outstanding. At March 31, 2012, there were approximately 61.9 million shares issued and outstanding.

14

Employee Stock Purchase Plan

The Company had in effect the 1998 Employee Stock Purchase Plan (1998 Plan) under which 4.8 million shares of common stock was reserved for issuance. In August 2010, the Company’s stockholders approved the proposal to increase the number of shares reserved for issuance to 6.3 million shares. In August 2012, the Company’s stockholders approved the proposal to reserve an additional 1.8 million shares under the 2012 Employee Stock Purchase Plan (2012 Plan). Upon adoption of the 2012 Plan, the 1998 Plan was terminated. Under the terms of the 2012 Plan, purchases are made semiannually and the purchase price of the common stock is equal to 85% of the fair market value of the common stock on the first or last day of the offering period, whichever is lower. During the nine months ended December 31, 2012 and 2011, 0.4 million shares for each of these periods were issued under the 1998 Plan. At December 31, 2012, 6.6 million shares had been issued under all previous stock plans and none were available for future issuance, and 1.8 million shares were available for issuance under the 2012 Plan.

Stock Repurchase Program

In August 2004, the Board authorized a stock repurchase program for the repurchase of up to $200.0 million of the Company’s common stock. Under the program, the Company is authorized to make purchases in the open market or enter into structured stock repurchase agreements. In October 2008, the Board increased the stock repurchase program by $100.0 million. During the nine months ended December 31, 2012, approximately 0.1 million shares were repurchased on the open market at a weighted average price of $5.18 per share. During nine months ended December 31, 2011, approximately 3.5 million shares were repurchased on the open market at a weighted average price of $5.98 per share. From the time the program was first implemented in August 2004, the Company has repurchased on the open market a total of 17.3 million shares at a weighted average price of $10.04 per share. All repurchased shares were retired upon delivery to the Company.

The Company also utilizes structured stock repurchase agreements to buy back shares which are prepaid written put options on its common stock. The Company pays a fixed sum of cash upon execution of each agreement in exchange for the right to receive either a pre-determined amount of cash or stock depending on the closing market price of its common stock on the expiration date of the agreement. Upon expiration of each agreement, if the closing market price of its common stock is above the pre-determined price, the Company will have its cash investment returned with a premium. If the closing market price is at or below the pre-determined price, the Company will receive the number of shares specified at the agreement inception. The Company considered the guidance in ASC Topic 480-10, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity and ASC Topic 815-40, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock. Any cash received, including the premium, is treated as additional paid-in capital on the balance sheet.

During the nine months ended December 31, 2012, the Company did not enter into any structured stock repurchase agreements. During nine months ended December 31, 2011, the Company entered into structured stock repurchase agreements totaling $10.0 million for which it received 1.0 million in shares of its common stock at an effective purchase price of $9.74 per share from the settled structured stock repurchase agreements. At December 31, 2011, the Company had no outstanding structured stock repurchase agreements. From the inception of the Company’s most recent stock repurchase program in August 2004, it entered into structured stock repurchase agreements totaling $277.5 million. Upon settlement of these agreements, as of December 31, 2012, the Company received $179.8 million in cash and 10.0 million shares of its common stock at an effective purchase price of $9.78 per share.

The table below is a plan-to-date summary of the Company’s repurchase program activity as of December 31, 2012 (in thousands, except per share data):

	Aggregate Price		Repurchased Shares	Average Price Per Share
Stock repurchase program
Authorized amount	$	300,000	—	$	—
Open market repurchases	173,611		17,284	10.04
Structured stock repurchase agreements*	110,517		9,989	11.06
Total repurchases	$	284,128	27,273	$	10.42
Available for repurchase	$	15,872

* The amounts above do not include gains recorded to additional paid-in-capital of $12.8 million from structured stock repurchase agreements which settled in cash. The average price per share for structured stock repurchase agreements adjusted for gains from settlements in cash would have been $9.78 per share and for total repurchases would have been $9.97 per share.

Stock Options

The Company has granted stock options to employees and non-employee directors under several plans. These option plans include two stockholder-approved plans (the 1992 Stock Option Plan and 1997 Directors’ Stock Option Plan) and four plans not approved by stockholders (the 2000 Equity Incentive Plan, Cimaron Communications Corporation’s 1998 Stock Incentive Plan assumed in the fiscal 1999 merger, and JNI Corporation’s 1997 and 1999 Stock Option Plans assumed in the fiscal 2004 merger). Certain other outstanding options were assumed through the Company’s various acquisitions.

In April 2011, the Compensation Committee and the Board of Directors approved the Company’s 2011 Equity Incentive Plan (“2011 Plan”). The Company’s stockholders approved the 2011 Plan during its August 2011 annual meeting. The 2011 Plan serves as a successor to the 1992 Plan and no additional equity awards will be granted under the 1992 Plan. The total number of shares of common stock reserved for issuance under the 2011 Plan consists of 4.2 million shares plus up to 10.9 million shares subject to any stock awards under the 1992 Plan or the 2000 Plan that terminate or are forfeited or repurchased and would otherwise be returned to the share reserve under the 1992 Plan or the 2000 Plan, respectively.

The Board has delegated administration of the Company’s equity plans to the Compensation Committee, which generally determines eligibility, vesting schedules and other terms for awards granted under the plans. Options under the plans expire not more than ten years from the date of grant and are generally exercisable upon vesting. Vesting generally occurs over four years. New hire grants generally vest and become exercisable at the rate of 25% on the first anniversary of the date of grant and ratably on a monthly basis over a period of 36 months thereafter; subsequent option grants to existing employees generally vest and become exercisable ratably on a monthly basis over a period of 48 months measured from the date of grant.

In May 2009, Dr. Gopi, our CEO, was awarded 300,000 stock options for “Extraordinary Accomplishment.” The Black-Scholes value of these stock options is $1.1 million. These options will vest only if Company performance milestones are satisfied; otherwise they will expire unvested. The first milestone for 75,000 shares will vest only if we achieve an annual revenue target of $270 million or more for any fiscal year from fiscal 2010 through fiscal 2013. The next milestone for another 75,000 shares will vest only if we achieve an annual revenue target of $310 million or more for any fiscal year from fiscal 2010 through fiscal 2013 or an annual revenue target of $350 million or more for fiscal 2014. The last milestone for 150,000 shares will vest only if we achieve an annual operating margin of 13.5% of annual revenue or higher in fiscal 2013 or 15% or higher for any fiscal year from fiscal 2010 through fiscal 2012. The Company evaluates the probability of achieving the milestones and adjusts any stock option expense accordingly.

At December 31, 2012 and March 31, 2012, there were no shares of common stock subject to repurchase. Options are granted at prices at least equal to fair value of the Company’s common stock on the date of grant.

Option activity under the Company’s stock incentive plans during the nine months ended December 31, 2012 is set forth below (in thousands, except per share data):

	Number of Shares		Weighted Average Exercise Price Per Share
Outstanding at the beginning of the year	4,164		$	10.67
Granted	40		5.58
Exercised	(110	)	5.22
Forfeited	(406	)	15.56
Outstanding at the end of the period	3,688		$	10.24
Vested and expected to vest at the end of the period	3,675		$	10.25
Vested at the end of the period	3,105		$	10.50

At December 31, 2012, the weighted average remaining contractual term for options outstanding and vested is 3.3 years each.

The aggregate pretax intrinsic value of options exercised during the nine months ended December 31, 2012 was approximately $0.1 million. This intrinsic value represents the excess of the fair market value of the Company’s common stock on the date of exercise over the exercise price of such options.

16

The weighted average remaining contractual life and weighted average per share exercise price of options outstanding and of options exercisable as of December 31, 2012 were as follows (in thousands, except exercise prices and years):

	Options Outstanding				Options Exercisable
Range of Exercise Prices	Number of Shares	Weighted Average Remaining Contractual Life	Weighted Average Exercise Price		Number of Shares	Weighted Average Exercise Price
$  1.68 - $ 7.12	843	2.96	$	6.54	503	$	6.18
7.13 - 8.07	853	3.81	7.71		823	7.70

$  1.68 - $24.16	3,688	3.33	$	10.24	3,105	$	10.50

As of December 31, 2012, the aggregate pre-tax intrinsic value of options outstanding and exercisable was approximately $2.2 million and $1.8 million. The aggregate pre-tax intrinsic values were calculated based on the closing price of the Company’s common stock of $8.42 on December 31, 2012.

Restricted Stock Units

The Company has granted restricted stock units (“RSUs”) pursuant to its 1992 Plan, 2000 Equity Incentive Plan and 2011 Equity Incentive Plan as part of its regular annual employee equity compensation review program as well as to new hires. RSUs are share awards that, upon vesting, will deliver to the holder, shares of the Company’s common stock. Generally, RSUs vest ratably on a quarterly basis over four years from the date of grant. For employees hired after May 15, 2006, RSUs will vest on a quarterly basis over four years from the date of hire provided that no shares will vest during the first year of employment, at the end of which the shares that would have vested during that year will vest and the remaining shares will vest over the remaining 12 quarters.

In May 2009, the Company issued three years performance-based RSU grants, or “EBITDA” Grants which were completed in fiscal 2012 and no additional grants will be made under this grant.

In April 2011, the Committee authorized additional three years performance-based RSU grants, or “EBITDA2” Grants. EBITDA2 Grants are similar to the EBITDA Grant program introduced in 2009. The Company evaluates the probability of achieving the milestones and adjusts any RSU expense which is included in stock-based compensation expense. The Company believes that that it would be highly unlikely for any EBITDA2 shares to vest during the three-year life of the program. Fiscal 2012 was declared zero attainment and vesting target shares have rolled over to fiscal 2013. The Company expects that all shares issued under the EBITDA2 program will expire unvested when the program concludes in May 2014.

In November 2011 and February 2012, the Committee authorized additional 18 months performance-based RSU grants, or “Performance Retention Grants”, which are intended to incentivize superior performance and retain key employees. In May 2012, the Committee authorized 12 months Performance Retention Grants. Vesting for the Performance Retention Grants is subject to (i) the accomplishment of goals and objectives of the individual’s business unit and (ii) individual performance as measured by the accomplishment of individual goals and objectives. The 18-month RSU shares generally vest 2/3 after one year, with certain unearned amounts able to roll over to the subsequent vesting period, and 1/3 after 18 months. The 12-month RSU shares will have the opportunity to vest after 1 year. Unvested RSU shares remaining at the end of the program period will expire unvested. The Company evaluates the probability of achieving the goals and objectives and adjusts any RSU expense which is included in stock-based compensation expense.

In February 2012, Dr. Gopi was awarded 500,000 restricted stock units. The value of these restricted stock units is $3.7 million. These awards will vest only if the Company’s performance milestones relating to the Veloce merger are satisfied; otherwise they will expire unvested. The Company evaluates the probability of achieving the milestones and recognizes expense accordingly. During the three and nine months ended December 31, 2012, two of the performance milestones were assessed of being probable of completion and their associated expense has been recorded in the Company's financial statements during these periods.

17

Restricted stock unit activity during the nine months ended December 31, 2012 is set forth below (in thousands):

	Restricted Stock Units Outstanding Number of Shares
Outstanding at the beginning of the year	9,244
Awarded	894
Vested	(2,152	)
Cancelled	(1,322	)
Outstanding at the end of the period	6,664

The weighted average remaining contractual term for the restricted stock units outstanding as of December 31, 2012 was 1.4 years.

As of December 31, 2012, the aggregate pre-tax intrinsic value of restricted stock units outstanding was $56.1 million which includes performance based awards which are subject to milestone attainment. The aggregate pretax intrinsic values were calculated based on the closing price of the Company’s common stock of $8.42 on December 31, 2012.

The aggregate pretax intrinsic value of RSUs released during the nine months ended December 31, 2012 was $13.0 million. This intrinsic value represents the fair market value of the Company’s common stock on the date of release.

Warrants

On May 17, 2009, the Company entered into a development agreement with Veloce pursuant to which Veloce agreed, among other things, to perform development work for the Company on an exclusive basis for up to five years for cash and other consideration, including a warrant to purchase shares of the Company’s common stock (the “Warrant”). The Warrant vesting schedule was amended in conjunction with the amended development agreement on November 8, 2010. In connection with the Merger Agreement amendment entered into on April 5, 2012, the Company and Veloce further modified the Warrant by fully accelerating the vesting schedule resulting in the recognition of approximately $1.3 million of stock compensation expense during the quarter ended June 30, 2012. All vested shares were subsequently sold and the proceeds distributed, prior to the acquisition of Veloce by the Company on June 20, 2012.

6. STOCK-BASED COMPENSATION

The Company accounts for stock based compensation activity using the modified prospective method. This method requires companies to estimate the fair value of stock-based compensation on the date of grant using an option-pricing model. The Company uses the Black-Scholes model to value stock-based compensation, excluding RSUs, which we use the fair market value of our common stock. The Black-Scholes model determines the fair value of share-based payment awards based on the stock price on the date of grant and is affected by assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, the Company’s stock price, volatility over the term of the awards and actual and projected employee stock option exercise behaviors. Option-pricing models were developed for use in estimating the value of traded options that have no vesting or hedging restrictions and are fully transferable. Although the fair value of stock options granted by the Company is estimated by the Black-Scholes model, the estimated fair value may not be indicative of the fair value observed in a willing buyer/willing seller market transaction.

The Company did not grant options during the three months ended December 31, 2012 and 2011. The fair value of the options granted during the nine months ended December 31, 2012 and 2011 is estimated as of the grant date using the Black-Scholes option-pricing model assuming the weighted-average assumptions listed in the following table:

	Nine Months Ended December 31,
	Employee Stock Options						Employee Stock Purchase Plans
	2012			2011			2012			2011
Expected life (years)	4.5			3.8			0.5			0.5
Risk-free interest rate	0.7		%	1.4		%	0.2		%	0.2		%
Volatility	54		%	48		%	50		%	55		%
Dividend yield	—			—			—			—
Weighted average fair value	$	2.47		$	3.83		$	1.50		$	1.92

18

The weighted average grant-date fair value per share of the restricted stock units awarded was $6.13 and $5.71 during the three and nine months ended December 31, 2012, respectively, compared to $8.02 and $9.21 during the three and nine months ended December 31, 2011, respectively. The weighted average fair value per share was calculated based on the fair market value of the Company’s common stock on the respective grant dates.

Effective April 1, 2012, the Company revised its estimated forfeiture rate used in determining the amount of stock-based compensation from 6.8% to 6.6% as a result of an decreasing rate of forfeitures in recent periods, which the Company believes is indicative of the rate it will experience during the remaining vesting period of currently outstanding unvested grants.

The following table summarizes stock-based compensation expense related to stock options and restricted stock units (in thousands):

	Three Months Ended					Nine Months Ended
	December 31,					December 31,
	2012		2011			2012		2011
Stock-based compensation expense by type of award
Stock options and warrants	$	935	$	1,646		$	3,024	$	4,207
Restricted stock units	5,276		2,824			18,427		7,533
Total stock-based compensation	6,211		4,470			21,451		11,740
Stock-based compensation expensed from/(capitalized to) inventory	11		(37		)	94		(5		)
Total stock-based compensation expense	$	6,222	$	4,433		$	21,545	$	11,735

The following table summarizes stock-based compensation expense as it relates to the Company’s condensed consolidated statement of operations (in thousands):

	Three Months Ended					Nine Months Ended
	December 31,					December 31,
	2012		2011			2012		2011
Stock-based compensation expense by cost centers
Cost of revenues	$	147	$	120		$	502	$	297
Research and development	2,814		2,647			10,733		6,761
Selling, general and administrative	3,250		1,703			10,216		4,682
Total stock-based compensation	$	6,211	$	4,470		$	21,451	$	11,740
Stock-based compensation expensed from/(capitalized to) inventory	11		(37		)	94		(5		)
Total stock-based compensation expense	$	6,222	$	4,433		$	21,545	$	11,735

The amount of unearned stock-based compensation currently estimated to be expensed from now through fiscal 2016, including time and performance based awards that are expected to vest, at December 31, 2012 is $12.6 million. The weighted-average period over which the unearned stock-based compensation is expected to be recognized is approximately 1.4 years. If there are any modifications or cancellations of the underlying unvested securities, the Company may be required to accelerate, increase or cancel any remaining unearned stock-based compensation expense. Future stock-based compensation expense and unearned stock-based compensation will increase to the extent that the Company grants additional equity awards or assumes unvested equity awards in connection with acquisitions.

The above stock based compensation expense of approximately $21.5 million for the nine months ended December 31, 2012 does not include approximately $1.3 million of expense related to the acceleration of Veloce warrants. See note 5 of Notes to Condensed Consolidated Financial Statements for further details relating to the Veloce warrants.

7. CONTINGENCIES

Legal Proceedings

The Company is currently a party to various legal proceedings, including those noted in this section. While Management presently believes that the ultimate outcome of these proceedings, individually and in the aggregate, will not materially harm

19

the Company's financial position, results of operations, cash flows, or overall trends, legal proceedings are subject to inherent uncertainties, unfavorable rulings or other events could occur. In addition, legal proceedings are expensive to prosecute and defend against and can divert Management attention and Company resources away from the Company's business objectives. Unfavorable resolutions could include monetary damages against the Company, or preclude the Company from recovering the damages it seeks in legal proceedings it has commenced. It is also possible that the Company could conclude it is in the best interests of its stockholders, employees, and customers to settle one or more such matters, and any such settlement could include substantial payments or the surrender of rights to collect substantial payments from third parties. However, The Company has not reached this conclusion with respect to any particular matter at this time.

In 1993, the Company was named as a Potentially Responsible Party (“PRP”) along with more than 100 other companies that used an Omega Chemical Corporation waste treatment facility in Whittier, California (the “Omega Site”). The U.S. Environmental Protection Agency (“EPA”) has alleged that Omega failed to properly treat and dispose of certain hazardous waste materials at the Omega Site. The Company is a member of a large group of PRPs, known as the Omega Chemical Site PRP Organized Group (“OPOG”) that has agreed to fund certain on-going remediation efforts at the Omega Site. In February 2001, the U.S. District Court for the Central District of California (the “Court”) approved a consent decree between EPA and OPOG to study contamination and evaluate cleanup options at the Omega Site (the Operable Unit 1 or “OU1”). In January 2009, the Court approved two amendments to the consent decree, the first expanding the scope of work to mitigate volatile organic compounds affecting indoor air quality near the Omega Site and the second adding settling parties to the consent decree. Removal of waste materials from the Omega Site has been completed. As part of OU1, efforts to remediate the soil and groundwater at the Omega Site, including without limitation the extraction of chemical vapors from the soil in and around the site, are underway and are expected to be ongoing for several years. In addition, OPOG and EPA are investigating a regional groundwater contamination plume allegedly originating at the Omega Site (the Operable Unit 2 or “OU2”). In September 2011, EPA issued an interim Record of Decision specifying the interim clean-up actions EPA has chosen for OU2, and in September 2012, it issued a special notice letter that triggered the commencement of good faith settlement negotiations with OPOG. It is anticipated that such settlement negotiations will result in EPA and OPOG entering into a remediation consent decree with the Court regarding OU2. In November 2007, Angeles Chemical Company, located downstream from the Omega Site, filed a lawsuit (the “Angeles Litigation”) in the Court against OPOG and the PRPs for cost recovery and indemnification for future response costs allegedly resulting from the regional groundwater contamination plume described above. In March 2008, the Court granted OPOG’s motion to stay the Angeles Litigation pending EPA’s determination of how to investigate and remediate the regional groundwater. In 2010, certain PRP’s challenged the criteria previously used to allocate liability among the PRP’s. In December 2011, an allocation committee established by OPOG to review those criteria recommended changes to the cost allocation structure that would, upon final approval, increase the Company’s overall share of liability within the PRP group. In addition, the recent departure of one or more PRPs from OPOG could have the effect of increasing the proportional liability of the remaining PRPs, including the Company. In January 2012, as a result of the allocation criteria modifications and PRP departure from OPOG described above, the Company’s proportional allocation of liability was increased. Although the Company considers a loss relating to the Omega Site probable, its share of any financial obligations for the remediation of the Omega Site, including taking into account the allocation increases described above, is not currently believed to be material to the Company’s financial statements, based on the Company’s approximately 0.5% contribution to the total waste tonnage sent to the site and current estimates of the potential remediation costs. Based on currently available information, the Company has a loss accrual that is not material and believes that the actual amount of its costs will not be materially different from the amount accrued. However, proceedings are ongoing and the eventual outcome of the clean-up efforts and the pending litigation matters is uncertain at this time. Based on currently available information, the Company does not believe that any eventual outcome will have a material adverse effect on its operations.

AppliedMicro TPack A/S, the Company’s wholly-owned subsidiary acquired in September 2010 (“TPack”), is involved in a contract dispute with Xtera Communications Inc. and its subsidiary Meriton Networks Canada Inc. (collectively, “Xtera”), regarding a software development and licensing agreement the parties entered into in September 2006. In August 2009, Xtera filed an action against TPack in the United States District Court for the Eastern Division of Texas, which was dismissed in October 2010 for lack of jurisdiction. In September 2009, TPack filed an action against Xtera in the Ontario Superior Court of Justice in Canada, which action was resumed in March 2011 following dismissal of the Texas action. In the Canadian action, TPack seeks contract damages from Xtera of approximately $1.0 million plus pre-judgment interest and expenses. In April 2011, Xtera filed a statement of defense and counter claim with the Ontario court, in which Xtera denies liability to TPack and seeks reimbursement of approximately $1.7 million in development fees and royalties previously paid to TPack, plus pre-judgment interest and expenses. Discovery in the legal proceedings is continuing. The Company does not currently anticipate that the TPack/Xtera legal proceedings will have a material adverse effect on the Company.

OVERVIEW

The Company

Applied Micro Circuits Corporation (“AppliedMicro”, “APM”, “AMCC”, the “Company”, “we” or “our”) is a leader in semiconductor solutions for the data center, enterprise, telecom and consumer/small medium business (“SMB”) markets. We design, develop, market, sell and support high-performance low power ICs, which are essential for the processing, transporting and storing of information worldwide. In the telecom and enterprise markets, we utilize a combination of design expertise coupled with system-level knowledge and multiple technologies to offer IC products for wireline and wireless communications equipment such as wireless access points, wireless base stations, multi-function printers, enterprise and edge switches, blade servers, storage systems, gateways, core switches, routers, metro, long-haul, and ultra-long-haul transport platforms. In the consumer/SMB markets, we combine optimized software and system-level expertise with highly integrated semiconductors to deliver comprehensive reference designs and stand-alone semiconductor solutions for wireline and wireless communications equipment such as wireless access points, network attached storage, and residential and smart energy gateways. We are committed to our strategy to focus on the transition to converge computing and connectivity into the Data Center which will create optimized total-cost-of-ownership solutions for cloud server workloads and position us towards the large growth data center market. Our corporate headquarters are located in Sunnyvale, California. Sales and engineering offices are located throughout the world.

We are a semiconductor company that possesses fundamental and differentiated intellectual property for high speed signal processing, packet based communications processors and telecommunications transport protocols. This intellectual property enables us to be a key player in the data center, enterprise and telecommunications applications. Our customer focus is on the OEMs and telecommunications companies that build and connect to data centers. As of December 31, 2012, our business had two reporting units, Computing and Connectivity.

21

Since the start of fiscal 2011, we have invested a total of $436.3 million in the R&D of new products, including higher-speed, lower-power and lower-cost products, products that combine the functions of multiple existing products into single highly-integrated solutions, and other products to expand and complete our portfolio of communications solutions including our ARM 64-bit based server product development. These products, and our customers’ products for which they are intended, are highly complex. Due to this complexity, it often takes several years to complete the development and qualification of a product before it enters into volume production. Accordingly, we have not yet generated significant revenues from some of the products developed during this time period. In addition, downturns in the telecommunications market can severely impact our customers’ business and often result in significantly less demand for our products than was expected when the development work commenced.

We implemented a restructuring program during the three months ended December 31, 2012to reorganize our operations and reduce our workforce and related operating expenses. The plan includes eliminating job redundancies and reducing our current workforce by approximately 70 employees. As a result, we recorded a charge of $1.5 million for employee severances and $4.7 million for an asset impairment. The asset impairment related to the impairment of the unamortized value of a software intellectual property license, which the Company no longer intends to use to develop new products.

We expect to incur cash expenditures of approximately $1.2 million to $1.4 million during the current fiscal year ending March 31, 2013 for employee severances and anticipate that the restructuring plan will reduce ongoing headcount expenses by approximately $8.0 million to $9.0 million annually and other additional operational expenses by $4.0 million to $5.0 million annually. We expect the restructuring program to be completed by the end of its current fiscal year ending March 31, 2013.

Acquisition of Veloce

On June 20, 2012 (the “Closing Date”), the Company completed its acquisition of Veloce pursuant to the terms of the Agreement and Plan of Merger, entered into as of May 17, 2009 (the “Initial Agreement”), as amended by Amendment No. 1 to Agreement and Plan of Merger, entered into as of November 8, 2010 (the “First Amendment”), and Amendment No. 2 to Agreement and Plan of Merger, entered into as of April 5, 2012 (the “Second Amendment” and, collectively with the Initial Agreement and the First Amendment, the “Merger Agreement”). The First Amendment was amended, restated and replaced in its entirety by the Second Amendment. The Merger is treated as a “reorganization” under Section 368 of the Internal Revenue Code.

The terms of the Merger Agreement include the payment of initial consideration of up to $60.4 million, payable in shares of Company common stock and/or cash (at the Company's election) to holders of Veloce common stock, Veloce stock options that were vested on the Closing Date, and holders of Veloce stock equivalents (collectively, “Veloce Equity Holders”). During the three and nine months ended December 31, 2012, as part of the above arrangement, the Company issued 0.2 million shares valued at $1.1 million and 2.9 million shares valued at $16.0 million, respectively, and paid approximately $1.1 million and $15.9 million in cash, respectively. Of the $60.4 million that relates to the initial consideration, $31.9 million has been paid to date. To the extent payments of the $60.4 million are paid in the Company's common stock and relate to shares of Veloce stock that were outstanding at the date of the closing of the Merger, the value of the Company's common stock is fixed at $5.546 per share (“fixed shares”). The balance of the $60.4 million or approximately $28.5 million will be paid over multiple quarters and will include approximately 1.2 million fixed shares and at least $10.2 million in cash for a total value of $16.9 million. The remaining $11.6 million of the $28.5 million will be paid in a combination of cash and shares of the Company's common stock valued at the then-current market price.

For accounting purposes, the consideration payable for the acquisition of Veloce is considered compensatory and is recognized as research and development expense when incurred. Recognition of these costs will occur when the specific development and performance milestones become probable of achievement and the amount of expense will be based upon the estimated stage of product development to date. As of March 31, 2012, the first development and performance milestone set forth under the Merger Agreement was considered probable of achievement and the Company recognized $60.4 million of expense.

The total estimated value to the Veloce Equity Holders is based on the Company achieving certain performance benchmarks defined under the Merger Agreement within a certain time period. The Company performed various simulations during the three months ended December 31, 2012. The results of the simulations exceeded expectations for certain of the benchmarks defined under the Merger Agreement, and as a result the estimated maximum value to the Veloce Equity Holders was increased from approximately $135 million to the contractual maximum of $178.5 million, based on the Company's current expectations regarding the achievement of such product development milestones. As such, the total estimated value to the Veloce Equity Holders has been updated to be in the range of $117 million to $178.5 million, depending upon the achievement of multiple product development milestones and technical performance results. The increase in the estimated value to the Veloce Equity Holders also resulted in an increase of the estimated value of the first performance milestone. Research and Development expense recognized during the three months ended December 31, 2012 relating to the first performance milestone

22

was based upon the estimated stage of the development of the first milestone as of December 31, 2012 and the estimated value tied to the first performance milestone. The remaining costs associated with the first performance milestone, estimated value of the first milestone less expense recognized through December 31, 2012, will be recognized on a straight line basis, subject to adjustment for actual progress towards the milestones, over the remaining period of expected development which is currently estimated not to exceed the next three fiscal quarters.

Additionally, during the three months ended December 31, 2012, the second development and performance milestone set forth under the Merger Agreement was considered probable of achievement. The Company recognized research and development expenses that were based upon the estimated stage of development and estimated value tied to the second performance milestone. The remaining costs associated with the second performance milestone will be recognized on a straight line basis, subject to adjustment for actual progress towards the milestones, over the remaining period of expected development which is currently estimated not to exceed the next three fiscal quarters.

The third and last development and performance milestone set forth under the Merger Agreement was not yet considered probable of achievement as of December 31, 2012.

Total research and development expenses expected to be recognized upon completion of the first and second performance milestones is approximately $142.8 million (including the initial consideration of $60.4 million), of which approximately $117 million has been recognized through December 31, 2012. During the three and nine months ended December 31, 2012, expenses recognized in connection with first and second performance milestones were $51.9 million and $56.6 million, respectively. The amount and timing of expense recognition is determined based upon the probability of the respective performance milestone being achieved, the estimated progress of development, and estimated date of the milestone attainment. Timing of payments will be based upon actual attainment of the development and performance milestones, and upon vesting, if any, associated with outstanding Veloce' stock equivalents.

Of the total of approximately $142.8 million which is expected to be due to Veloce upon the attainment of the first two development and performance milestones and expected to be paid over multiple quarters, $31.9 million has been paid to date and the Company expects that approximately another $77 million will be paid in cash and stock by September 30, 2013.

Net Revenues. We generate revenues primarily through sales of our IC products, embedded processors and printed circuit board assemblies to OEMs, such as Alcatel-Lucent, Ciena, Cisco, Brocade, Fujitsu, Hitachi, Huawei, Juniper, Ericsson, NEC, Nokia Siemens Networks, and Tellabs, who in turn supply their equipment principally to communications service providers.

On a sell-through basis, we had approximately 61 days of inventory in the distributor channel at December 31, 2012 as compared to 65 days at December 31, 2011. The decrease in inventory days was due to a further decline in amounts sold into the distributor channel than the amounts sold through during the quarter ended December 31, 2012 as compared to the quarter ended December 31, 2011.

The gross margins for our solutions have historically declined over time. Some factors that we expect to cause downward pressure on the gross margins for our products include competitive pricing pressures, unfavorable product mix, the cost sensitivity of our customers particularly in the higher-volume markets, new product introductions by us or our competitors, and capacity constraints in our supply chain. From time to time, for strategic reasons, we may accept orders at less than optimal gross margins in order to facilitate the introduction of, or, market penetration of our new or existing products. To maintain acceptable operating results, we will need to offset any reduction in gross margins of our products by reducing costs, increasing sales volume, developing and introducing new products and developing new generations and versions of existing products on a timely basis.

We classify our revenues into two categories based on the markets that the underlying products serve. The categories are Computing and Connectivity. We use this information to analyze our performance and success in these markets including our strategy to focus on the transition to the large growth data center market.

We are continuing to focus our current connectivity investments on high growth 10G and faster Ethernet solutions, data center, Optical Transport Network (“OTN”) and enterprise market opportunities while continuing to service the Telecom (SONET/SDH) market. Over time, we believe customers will transition from the SONET/SDH standard to higher speed, lower power products that utilize the OTN standard in order to support the increasing demand for transmission of data over networks. However, the timing and extent of this transition is uncertain due to the significant investment that is needed to convert networks to the OTN standard. As such, the rate of conversion to the OTN standard is, in part, greatly influenced by global economic market conditions. Recessionary type market conditions will result in a slower transition of networks to the OTN standard. Additionally, there can be no assurance that our revenues will increase as the OTN standard is adopted.

The portion of our business represented by connectivity revenues attributable to our OTN and 10 gigabit or faster Ethernet products and that attributable to our SONET/SDH and Legacy Switch products for the year ended March 31, 2012 was 59% and 41%, respectively.

24

The following table presents the portion of our business represented by connectivity revenues attributable to our OTN and 10 gigabit or faster Ethernet products and that attributable to our SONET/SDH and Legacy Switch products for the three and nine months ended December 31, 2012 and 2011:

	Three Months Ended				Nine Months Ended
	December 31,				December 31,
	2012		2011		2012		2011
OTN and 10G Ethernet products	80	%	75	%	77	%	57	%
SONET, SDH (including Switch) products	20	%	25	%	23	%	43	%
	100	%	100	%	100	%	100	%

The demand for our products has been affected in the past, and may continue to be affected in the future, by various factors, including, but not limited to, the following:

• the timing, rescheduling or cancellation of significant customer orders and our ability, as well as the ability of our customers, to manage inventory corrections;

• the qualification, availability and pricing of competing products and technologies and the resulting effects on the sales, pricing and gross margins of our products;

• our ability to specify, develop or acquire, complete, introduce, and market new products and technologies in a cost effective and timely manner;

• the rate at which our present and future customers and end-users adopt our products and technologies in our target markets;

• general economic and market conditions in the semiconductor industry and communications markets;

• combinations of companies in our customer base, resulting in the combined company choosing our competitor’s IC standardization rather than our supported product platforms;

• the gain or loss of one or more key customers, or their key customers, or significant changes in the financial condition of one or more of our key customers or their key customers;

• our expectation of a market ramp for our products could be incorrect and such ramp could get pushed out or not happen at all;

• our ability to meet customer demand due to capacity constraints at our suppliers; and

• natural disasters that could affect our supply chain or our customer’s supply chain which would affect their requirements of our products.

For these and other reasons, our net revenue and results of operations for the three and nine months ended December 31,2012 may not necessarily be indicative of future net revenue and results of operations.

Based on direct shipments, net revenues to customers that were equal to or greater than 10% of total net revenues were as follows (in thousands):

	Three Months Ended				Nine Months Ended
	December 31,				December 31,
	2012		2011		2012		2011
Wintec (global logistics provider)	21	%	19	%	20	%	21	%
Avnet (distributor)	27	%	23	%	28	%	19	%
Flextronics (sub-contract manufacturer)	*		*		*		11	%

* Less than 10% of total net revenues.

We expect that our largest customers will continue to account for a substantial portion of our net revenue for the foreseeable future.

* Change in revenues was primarily due to shift in customer demand and continuing geographic changes to macro-economic conditions.

Our revenues are primarily denominated in U.S. dollars, other than revenues that account for less than 10% of our total revenues, which are denominated primarily in the Danish Kroner.

Key non-GAAP measurements. We use certain non-GAAP metrics such as Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (“Adjusted EBITDA”) to measure our performance. We define Adjusted EBITDA as net (loss) income, less interest income, income taxes, depreciation and amortization, stock-based compensation, amortization of intangibles and other one-time and/or non-cash items.

The following table reconciles Adjusted EBITDA to the accompanying financial statements (in thousands):

	Three Months Ended						Nine Months Ended
	December 31,						December 31,
	2012			2011			2012			2011
Net loss	$	(71,562	)	$	(7,077	)	$	(116,509	)	$	(15,106	)

We believe that Adjusted EBITDA is a useful supplemental measure of our operation’s performance because it helps investors evaluate and compare the results of operations from period to period by removing the accounting impact of the company’s financing strategies, tax provisions, depreciation and amortization, restructuring charges, stock based compensation expense, Veloce accrued liability and certain other operating items. We adjust for these excluded items because we believe that, in general, these items possess one or more of the following characteristics: their magnitude and timing is largely outside of the company’s control; they are unrelated to the ongoing operations of the business in the ordinary course; they are unusual or infrequent and the company does not expect them to occur in the ordinary course of business; or they are non-cash expenses.

Adjusted EBITDA is not a measure determined in accordance with generally accepted accounting principles in the United States, or GAAP, and should not be considered a substitute for operating income, net income or any other measure determined in accordance with GAAP. Adjusted EBITDA should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. Adjusted EBITDA is used by our management as a measure of operating efficiency and overall financial performance for benchmarking against our peers and competitors and is used as a metric to determine the performance vesting of our three-year RSU grants issued in May 2009 (the “EBITDA Grants”) and May 2011 (the “EBITDA2 Grants”). Management believes Adjusted EBITDA provides meaningful supplemental information regarding the underlying operating performance of our business. Management also believes that Adjusted EBITDA is useful to investors because it is frequently used by securities analysts, investors and other interested parties to evaluate the company.

The book-to-bill ratio is another metric commonly used by investors to compare and evaluate technology and semiconductor companies. The book-to-bill ratio is a demand-to-supply ratio that compares the total amount of orders received to the total amount of orders filled. This ratio tells whether the company has more orders than it delivered (if greater than 1), has the same amount of orders that it delivered (equals 1), or has less orders than it delivered (under 1). Though the ratio provides an indicator of whether orders are rising or falling, it does not consider the timing of or if the order will result in future revenues and the effect of changing lead times on bookings. Our book-to-bill ratio at December 31, 2012 and 2011 was 1.3 and 0.9, respectively.

CRITICAL ACCOUNTING POLICIES

The preparation of financial statements in accordance with accounting principles generally accepted in the United States 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: inventory valuation and capitalized mask set costs, which affect our cost of sales and gross profit; the valuation of goodwill and purchased intangibles, which has in the past affected, and could in the future affect, our impairment charges to write down the carrying value of purchased intangibles and the amount of related periodic amortization expense recorded for definite-lived intangibles; the valuation of the Veloce consideration which affects operating expenses; and an evaluation of other-than-temporary impairment of our investments, which affects the amount and timing of write-down charges. We also have other key accounting policies, such as our policies for stock-based compensation and revenue recognition. The methods, estimates and judgments we use in applying these critical accounting policies have a significant impact on the results we report in our financial statements. We base our estimates and assumptions on historical experience and on 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 that are not readily apparent from other sources. The actual results experienced by us may differ materially and adversely from management’s estimates. To the extent there are material differences between our estimates and the actual results, our future results of operations will be affected.

We believe the following critical accounting policies require us to make significant judgments and estimates in the preparation of our consolidated financial statements.

Investments

We hold a variety of securities that have varied underlying investments. We review our investment portfolio periodically to assess for other-than-temporary impairment. We assess the existence of impairment of our investments in order to determine the classification of the impairment as “temporary” or “other-than-temporary”. The factors used to determine whether an impairment is temporary or other-than-temporary involves considerable judgment. The factors we consider in determining whether any individual impairment is temporary or other-than-temporary are primarily the length of the time and the extent to which the market value has been less than amortized cost, the nature of underlying assets (including the degree of collateralization), the financial condition, credit rating, market liquidity conditions and near-term prospects of the issuer. If the fair value of a debt security is less than its amortized cost basis at the balance sheet date, an assessment would have to be made as to whether the impairment is other-than-temporary. If we decided to sell the security, an other-than-temporary impairment shall be considered to have occurred. However, if we do not intend to sell the debt security, we shall consider available evidence to assess whether it is more likely than not we will be required to sell the security before the recovery of its amortized

27

cost basis due to cash, working capital requirements, contractual or regulatory obligations indicate that the security will be required to be sold before a forecasted recovery occurs. If it is more likely than not that we are required to sell the security before recovery of its amortized cost basis, an other-than-temporary impairment is considered to have occurred. If we do not expect to recover the entire amortized cost basis of the security, we would not be able to assert that we will recover its amortized cost basis even if we do not intend to sell the security. Therefore, in those situations, an other-than-temporary impairment shall be considered to have occurred. We use present value cash flow models to determine whether the entire amortized cost basis of the security will be recovered. We will compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. An other-than-temporary impairment is said to have occurred if the present value of cash flows expected to be collected is less than the amortized cost basis of the security. During the three and nine months ended December 31, 2012 and fiscal year ended March 31, 2012, we did not record any other-than-temporary impairment charges. As of December 31, 2012, we did not record an impairment charge in connection with securities in a loss position (fair value less than carrying value) with unrealized losses of $1.2 million as we believe that such unrealized losses are temporary. In addition, we also had $7.3 million in unrealized gains.

Veloce Consideration

We periodically evaluate the progress of the development work that is performed by Veloce, in connection with our contractual arrangement with Veloce. Based on such an evaluation as well as considering various other qualitative factors, we estimate the total value of the development work being performed by Veloce, and assess the timing and probability of attaining contractually defined performance milestones.

Upon assessing a performance milestone as probable of achievement, the amount of research and development expense that is recognized is based upon the estimated stage of development of that milestone and the estimated value associated with each performance milestone. The consideration that we will pay for each performance milestone is based upon the timing of when the performance milestone is completed.

Significant judgment is required to estimate the total value of the Veloce development work, assess when a performance milestone is probable of achievement and estimating the timing of when the performance milestones will be completed.

The estimated total value of the Veloce consideration is currently based upon the benchmarks that were achieved during simulations that were performed during the three months ended December 31, 2012 and correlating the results of the simulations to the contractual terms included in the Merger Agreement. As a result of higher than expected benchmarks achieved during simulations, the total estimated value to the Veloce Equity Holders has been updated from a previous estimated maximum of $135 million to the contractual maximum of $178.5 million. As a result of this increase in value, the estimated value relating to the first performance milestone was also increased. The additional expense recognized as a result of the increased value reflects the estimated stage of development for the first performance milestone as of December 31, 2012.

We rely on discussions with internal technical personnel and using various qualitative and quantitative factors, including, but not limited to, overall complexity, stage of development and progress made to date, results of testing, and consideration as to the nature of the remaining development work, to assess probability of attaining the performance milestones defined in the Merger Agreement. If based on our assessment we believe attainment of a performance milestone is probable, we will recognize expenses related to the estimated stage of development for the performance milestone. During the quarter ended December 31, 2012, we assessed the second performance milestone to be probable of achievement. Currently we believe that the first two performance milestones are probable of attainment. Upon completion, the estimated value of these two performance milestone will be $142.8 million. We have expensed as research and development expense, approximately $117 million through December 31, 2012. The third and final performance milestone is currently not yet believed to be probable of attainment.

We periodically assess the developmental progress made towards the attainment of the various milestones and rely on internal discussions with technical personnel to assess the stage of development for a particular performance milestone and the estimated time to complete based on the respective work plan. This information is used in determining the amount of expense to recognize for a performance milestone once the performance milestone is deemed probable of achievement. This information is also utilized in determining the period over which to recognize the remaining expenses relating to the specific performance milestone. During the fiscal quarter ended December 31, 2012, the total estimated value of the Veloce consideration increased and we assessed the second performance milestone to be probable of achievement. The total expense recognized was based upon the estimated stage of development and value of the respective performance milestones. As of December 31, 2012, we estimate that the first two performance milestones were deemed probable of completion, and projected to be completed by no later than the next three fiscal quarters. The third and last performance milestone set forth under the Merger Agreement was not yet considered probable of achievement as of December 31, 2012.

28

Total research and development expenses expected to be recognized upon completion of the first and second performance milestones is approximately $142.8 million (including the initial consideration of $60.4 million), of which approximately $117 million has been recognized through December 31, 2012. During the three and nine months ended December 31, 2012, expenses recognized in connection with first and second performance milestones were $51.9 million and $56.6 million, respectively.

Inventory Valuation

Our policy is to value inventories at the lower of cost or market on a part-by-part basis. This policy requires us to make estimates regarding the market value of our inventories, including an assessment of excess or obsolete inventories. We determine excess and obsolete inventories based on an estimate of the future demand for our products within a specified time horizon, generally 12 months. The estimates we use for future demand are also used for near-term capacity planning and inventory purchasing and are consistent with our revenue forecasts. If our demand forecast is greater than our actual demand we may be required to take additional excess inventory charges, which would decrease gross margin and net operating results. Any impairment charges taken establishes a new cost basis for the underlying inventory and the cost basis for such inventory is not marked-up on changes in circumstances until a gain is realized upon its eventual sale. This accounting is consistent with the guidance provided by SAB Topic 5-BB. To illustrate the sensitivity of inventory valuations to future estimates, as of December 31, 2012, reducing our future demand estimate to six months would decrease our current inventory valuation by approximately $1.4 million and increasing our future demand forecast to 18 months would increase our current inventory valuation by approximately $0.4 million.

Purchased Definite-Lived Intangible Assets and Other Long-Lived Assets

We evaluate our long-lived assets such as property, plant and equipment and purchased intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate the carrying value of an asset or asset group may not be recoverable. The carrying value of an asset or asset group is not recoverable if the amount of undiscounted future cash flows the assets are expected to generate (including any net proceeds expected from the disposal of the asset) are less than its carrying value. When we identify an impairment has occurred, we reduce the carrying value of the assets to its comparable market value (if available and appropriate) or to its estimated fair value based on a discounted cash flow approach.

Revenue Recognition

We recognize revenue based on four basic criteria: 1) there is evidence that an arrangement exists; 2) delivery has occurred; 3) the fee is fixed or determinable; and 4) collectability is reasonably assured. We recognize revenue upon determination that all criteria for revenue recognition have been met. In addition, we do not recognize revenue until the applicable customer’s acceptance criteria have been met. The criteria are usually met at the time of product shipment. Our standard terms and conditions of sale do not allow for product returns and we generally do not allow product returns other than under warranty or stock rotation agreements. Revenue from shipments to distributors is recognized upon shipment. In addition, we record reductions to revenue for estimated allowances such as returns not pursuant to contractual rights, competitive pricing programs and rebates. These estimates are based on our experience with stock rotations and the contractual terms of the competitive pricing and rebate programs. Royalty revenues are recognized when cash is received, only when royalty amounts cannot be reasonably estimated. Royalty revenues are based upon sales of our customer’s products that include our technology.

Shipping terms are generally FCA (Free Carrier) shipping point. If actual returns or pricing adjustments exceed our estimates, we would record additional reductions to revenue.

From time to time we generate revenue from the sale of our internally developed IP. We generally recognize revenue from the sale of IP when all basic criteria outlined above are met, which is generally when the payments are received.

Mask Costs

We incur significant costs for the fabrication of masks used by our contract manufacturers to manufacture our products. If we determine, at the time the cost for the fabrication of masks are incurred, that technological feasibility of the product has been achieved, we consider the nature of these costs to be pre-production costs. Accordingly, such costs are capitalized as property and equipment under machinery and equipment and are amortized as cost of sales over approximately three years, representing the estimated production period of the product. We periodically reassess the estimated product production period for specific mask sets capitalized. If we determine, at the time fabrication mask costs are incurred, that either technological feasibility of the product has not occurred or that the mask is not reasonably expected to be used in production manufacturing or that the commercial feasibility of the product is uncertain, the related mask costs are expensed to R&D in the period in which the costs are incurred. We will also periodically assess capitalized mask costs for impairment. During the three and nine

29

months ended December 31, 2012, total mask costs capitalized was zero and $3.1 million, respectively. During the three and nine months ended December 31, 2011, total mask costs capitalized was $0.6 million and $1.8 million, respectively.

Stock-Based Compensation Expense

All share-based payments, including grants of stock options, restricted stock units and employee stock purchase rights, are required to be recognized in our financial statements based on their respective grant date fair values. The fair value of each employee stock option and employee stock purchase right is estimated on the date of grant using an option pricing model that meets certain requirements. We currently use the Black-Scholes option pricing model to estimate the fair value of our share-based payments, excluding RSUs, which we use the fair market value of our common stock. The fair values generated by the Black-Scholes model may not be indicative of the actual fair values of our stock-based awards as it does not consider certain factors important to stock-based awards, such as continued employment, periodic vesting requirements and limited transferability. The determination of the fair value of share-based payment awards utilizing the Black-Scholes model is affected by our stock price and a number of assumptions, including expected volatility, expected life, risk-free interest rate and expected dividends. We estimate the expected volatility of our stock options at grant date by equally weighting the historical volatility and the implied volatility of our stock over specific periods of time as the expected volatility assumption required in the Black-Scholes model. The expected life of the stock options is based on historical and other data including life of the option and vesting period. The risk-free interest rate assumption is the implied yield currently available on zero-coupon government issues with a remaining term equal to the expected term. The dividend yield assumption is based on our history and expectation of dividend payouts. The fair value of our restricted stock units is based on the fair market value of our common stock on the date of grant. Forfeitures are required to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ significantly from those estimated. We evaluate the assumptions used to value stock-based awards on a quarterly basis. If factors change and we employ different assumptions, stock-based compensation expense may differ significantly from what we have recorded in the past. If there are any modifications or cancellations of the underlying unvested securities, we may be required to accelerate, increase or cancel any remaining unearned stock-based compensation expense. We currently estimate when and if performance-based grants will be earned. If the awards are not considered probable of achievement, no amount of stock-based compensation is recognized. If we consider the award to be probable, expense is recorded over the estimated service period. To the extent that our assumptions are incorrect, the amount of stock-based compensation recorded will be increased or decreased. To the extent that we grant additional equity securities to employees or we assume unvested securities in connection with any acquisitions, our stock-based compensation expense will be increased by the additional unearned compensation resulting from those additional grants or acquisitions.

RESULTS OF OPERATIONS

Comparison of the Three and Nine Months Ended December 31, 2012 to the Three and Nine Months Ended December 31, 2011

Net Revenues. Net revenues for the three and nine months ended December 31, 2012 were $51.7 million and $139.3 million, representing a decrease of 8.3% and 23.5% from net revenues of $56.3 million and $182.1 million for the three and nine months ended December 31, 2011, respectively. We classify our revenues into two categories based on the markets that the underlying products serve. The categories are Computing and Connectivity. We use this information to analyze our performance and success in these markets. See the following tables (dollars in thousands):

	Three Months Ended December 31,
	2012				2011
	Amount		% of Net Revenue		Amount		% of Net Revenue		(Decrease)			% Change
Computing	$	29,536	57.1	%	$	33,658	59.7	%	$	(4,122	)	(12.2	)%
Connectivity	22,162		42.9		22,689		40.3		(527		)	(2.3	)
	$	51,698	100.0	%	$	56,347	100.0	%	$	(4,649	)	(8.3	)%

	Nine Months Ended December 31,
	2012				2011
	Amount		% of Net Revenue		Amount		% of Net Revenue		(Decrease)			% Change
Computing	$	75,749	54.4	%	$	97,817	53.7	%	$	(22,068	)	(22.6	)%
Connectivity	63,567		45.6		84,303		46.3		(20,736		)	(24.6	)
	$	139,316	100.0	%	$	182,120	100.0	%	$	(42,804	)	(23.5	)%

30

During the three and nine months ended December 31, 2012, our Computing revenues declined by 12.2% and 22.6%, respectively, and our Connectivity revenues declined by 2.3% and 24.6%, respectively compared to the same periods last year. The overall revenue decline was spread across both the Computing and Connectivity product families and was as a result of lower demand for our products due to overall softness in the macro conditions and due to the roll-off of legacy products as we continue to focus on the development of our new products. In addition, the revenues for our Connectivity products were lower due to the delay in the overall OTN infrastructure build-out.

Gross Profit. The following table presents net revenues, cost of revenues and gross profit for the three and nine months ended December 31, 2012 and 2011 (dollars in thousands):

	Three months ended December 31,
	2012				2011
	Amount		% of Net Revenue		Amount		% of Net Revenue		Increase (Decrease)			% Change
Net revenues	$	51,698	100.0	%	$	56,347	100.0	%	$	(4,649	)	(8.3	)%
Cost of revenues	22,958		44.4		23,795		42.2		837			3.5
	$	28,740	55.6	%	$	32,552	57.8	%	$	(3,812	)	(11.7	)%

	Nine Months Ended December 31,
	2012				2011
	Amount		% of Net Revenue		Amount		% of Net Revenue		Increase (Decrease)			% Change
Net revenues	$	139,316	100.0	%	$	182,120	100.0	%	$	(42,804	)	(23.5	)%
Cost of revenues	61,874		44.4		77,830		42.7		15,956			20.5
	$	77,442	55.6	%	$	104,290	57.3	%	$	(26,848	)	(25.7	)%

The gross profit percentage for each of the three and nine months ended December 31, 2012 was 55.6% compared to 57.8% and 57.3% for the three and nine months ended December 31, 2011, respectively. The decrease in our gross profit percentage, excluding the impact of amortization of purchased intangibles, was 56.9% and 57.0%, and 59.0% and 58.8%, respectively, for the three and nine months ended December 31, 2012 and 2011, respectively. The decrease in our gross profit percentage was primarily due to lower licensing revenues, unfavorable product mix, lower overall revenues that have an impact on the absorption of fixed costs, and declining average selling prices.

The amortization of purchased intangible assets included in cost of revenues during the three and nine months ended December 31, 2012 and 2011 was $0.7 million and $2.0 million, and $0.7 million and $2.9 million, respectively. The decrease during the nine months ended December 31, 2012 and 2011 was primarily due to certain purchased intangible assets being fully amortized during the fiscal year ended March 31, 2012 resulting in a lower amortization charge in the three and nine months ended December 31, 2012.

Research and Development and Selling, General and Administrative Expenses. The following table presents research and development and selling, general and administrative expenses for the three and nine months ended December 31, 2012 and 2011 (dollars in thousands):

	Three Months Ended December 31,
	2012				2011
	Amount		% of Net Revenue		Amount		% of Net Revenue		Increase		% Change
Research and development	$	82,711	160.0	%	$	28,279	50.2	%	$	54,432	192.5	%
Selling, general and administrative	$	12,675	24.5	%	$	11,406	20.2	%	$	1,269	11.1	%

	Nine Months Ended December 31,
	2012				2011
	Amount		% of Net Revenue		Amount		% of Net Revenue		Increase		% Change
Research and development	$	151,865	109.0	%	$	86,256	47.4	%	$	65,609	76.1	%
Selling, general and administrative	$	38,676	27.8	%	$	32,903	18.1	%	$	5,773	17.5	%

Research and Development. Increases in research and development (“R&D”) expenses are primarily driven by the effect of a ramp-up in the costs relating to the ARM 64-bit silicon server development effort, and costs incurred on our developmental effort relating to other new products. Total consolidated R&D expenses consist primarily of salaries and related costs (including stock-based compensation) of employees engaged in research, design and development activities, costs related to engineering design tools, subcontracting costs and facilities expenses.

For accounting purposes, the consideration payable for the acquisition of Veloce is considered compensatory and is recognized as research and development expense when incurred. Recognition of these costs will occur when the specific development and performance milestones become probable of achievement and the amount of expense will be based upon the estimated stage of product development to date. As of March 31, 2012, the first development and performance milestone set forth under the Merger Agreement was considered probable of achievement and the Company recognized $60.4 million of expense.

The total estimated value to the Veloce Equity Holders is based on the Company achieving certain performance benchmarks defined under the Merger Agreement within a certain time period. The Company performed various simulations during the three months ended December 31, 2012. The results of the simulations exceeded expectations for certain of the benchmarks defined under the Merger Agreement, and as a result the estimated maximum value to the Veloce Equity Holders was increased from approximately $135 million to the contractual maximum of $178.5 million, based on the Company's current expectations regarding the achievement of such product development milestones. As such, the total estimated value to the Veloce Equity Holders has been updated to be in the range of $117 million to $178.5 million, depending upon the achievement of multiple product development milestones and technical performance results. The increase in the estimated value to the Veloce Equity Holders also resulted in an increase of the estimated value of the first performance milestone. Research and Development expense recognized during the three months ended December 31, 2012 relating to the first performance milestone was based upon the estimated stage of the development of the first milestone as of December 31, 2012 and the estimated value tied to the first performance milestone. The remaining costs associated with the first performance milestone, estimated value of the first milestone less expense recognized through December 31, 2012, will be recognized on a straight line basis, subject to adjustment for actual progress towards the milestones, over the remaining period of expected development which is currently estimated not to exceed the next three fiscal quarters.

Additionally, during the three months ended December 31, 2012, the second development and performance milestone set forth under the Merger Agreement was considered probable of achievement. The Company recognized research and development expenses that were based upon the estimated stage of development and estimated value tied to the second performance milestone. The remaining costs associated with the second performance milestone will be recognized on a straight line basis, subject to adjustment for actual progress towards the milestones, over the remaining period of expected development which is currently estimated not to exceed the next three fiscal quarters.

The third and last development and performance milestone set forth under the Merger Agreement was not yet considered probable of achievement as of December 31, 2012.

Total research and development expenses expected to be recognized upon completion of the first and second performance milestones is approximately $142.8 million (including the initial consideration of $60.4 million), of which approximately $117 million has been recognized through December 31, 2012. During the three and nine months ended December 31, 2012, expenses recognized in connection with first and second performance milestones were $51.9 million and $56.6 million, respectively. The amount and timing of expense recognition is determined based upon the probability of the respective performance milestone being achieved, the estimated progress of development, and estimated date of the milestone attainment. Timing of payments will be based upon actual attainment of the development and performance milestones, and upon vesting, if any, associated with outstanding Veloce' stock equivalents.

Of the total of approximately $142.8 million which is expected to be due to Veloce upon the attainment of the first two development and performance milestones and expected to be paid over multiple quarters, $31.9 million has been paid to date and the Company expects that approximately another $77 million will be paid in cash and stock by September 30, 2013.

The increase in R&D expenses of 192.5% for the three months ended December 31, 2012 compared to the three months ended December 31, 2011 was primarily due to $51.9 million for Veloce merger consideration costs, $1.7 million in third party foundry cost, $0.9 million in new product development costs, $0.7 million in consumable equipment and software cost, $0.3 million in customer funded non-recurring engineering payments and $0.2 million in stock-based compensation charges offset by a decrease of $0.8 million in contractor costs, engineering tools, supplies and other costs, $0.3 million in technology access fees and $0.2 million in printed circuit board costs. The increase in R&D expenses of 76.1% for the nine months ended December 31, 2012 compared to the nine months ended December 31, 2011 was primarily due $57.9 million for Veloce merger consideration costs (which includes approximately $1.3 million of expense related to the acceleration of Veloce warrants), $3.9

32

million in stock-based compensation charges, $2.1 million in consumable equipment and software cost, $1.1 million in third party foundry cost, $1.0 million in customer funded non-recurring engineering payments, $0.8 million each in personnel cost and product development costs and $0.3 million each in packaging cost and other engineering costs offset by a decrease of $1.7 million in technology access fees, $0.5 million in contractor cost and $0.4 million in printed circuit board cost.

We believe that a continued commitment to R&D is vital to our goal of maintaining a leadership position with innovative products. In addition to our internal R&D programs, our business strategy includes acquiring products, technologies or businesses from third parties. Future acquisitions of products, technologies or businesses may result in substantial additional on-going R&D costs.

Selling, General and Administrative. Selling, general and administrative (“SG&A”) expenses consist primarily of personnel related expenses (including stock-based compensation), professional and legal fees, corporate branding and facilities expenses. The increase in SG&A expenses of 11.1% for the three months ended December 31, 2012 compared to the three months ended December 31, 2011, was primarily due to $1.5 million in stock-based compensation charges and $0.6 million in professional and other service fees offset by a decrease of $0.3 million each in provision for doubtful debts and general administration costs and $0.2 million in corporate allocation expenses. The increase in SG&A expenses of 17.5% for the nine months ended December 31, 2012 compared to the nine months ended December 31, 2011, was primarily due to $5.5 million in stock-based compensation charges, $2.1 million relating to the reversal of previously accrued liabilities associated with an acquisition in the nine months ended December 31, 2011 (none in the nine months ended December 31, 2012) and $0.8 million in professional and other service fees offset by a decrease of $0.7 million in corporate allocation expenses, $0.6 million in marketing and travel costs, $0.5 million in provision for doubtful debts and $0.4 million each in personnel cost and sales commission cost. Future acquisitions of products, technologies or businesses may result in substantial additional on-going SG&A costs.

Stock-Based Compensation. The following table presents stock-based compensation expense for the three and nine months ended December 31, 2012 and 2011, which was included in the tables above (dollars in thousands):

	Three Months Ended December 31,
	2012				2011
	Amount		% of Net Revenue		Amount		% of Net Revenue		Increase		% Change
Costs of revenues	$	158	0.3	%	$	83	0.2	%	$	75	90.4	%
Research and development	2,814		5.4		2,647		4.7		167		6.3
Selling, general and administrative	3,250		6.3		1,703		3.0		1,547		90.8
	$	6,222	12.0	%	$	4,433	7.9	%	$	1,789	40.4	%

	Nine Months Ended December 31,
	2012				2011
	Amount		% of Net Revenue		Amount		% of Net Revenue		Increase		% Change
Costs of revenues	$	596	0.4	%	$	292	0.1	%	$	304	104.1	%
Research and development	10,733		7.7		6,761		3.7		3,972		58.7
Selling, general and administrative	10,216		7.3		4,682		2.6		5,534		118.2
	$	21,545	15.4	%	$	11,735	6.4	%	$	9,810	83.6	%

The increase in stock-based compensation of 40.4% and 83.6% during the three and nine months ended December 31, 2012 compared to the three and nine months ended December 31, 2011, respectively, was primarily due to the expense associated with the granting of new performance retention grants and other performance based awards. The stock based compensation expense of approximately $6.2 million and $21.5 million for the three and nine months ended December 31, 2012 does not include approximately $1.3 million of expense related to the acceleration of Veloce warrants. See note 5 of Notes to Condensed Consolidated Financial Statements for further details relating to the Veloce warrants. Stock-based compensation expense will continue to have a significant adverse impact on the Company’s reported results of operations, although it will have no impact on its overall financial position.

Restructuring Charges. We implemented a restructuring program during the three months ended December 31, 2012to reorganize our operations and reduce our workforce and related operating expenses. The plan includes eliminating job redundancies and reducing our current workforce by approximately 70 employees. As a result, we recorded a charge of $1.5

33

million for employee severances and $4.7 million for an asset impairment. The asset impairment related to the impairment of the unamortized value of a software intellectual property license, which the Company no longer intends to use to develop new products. We expect to incur cash expenditures of approximately $1.2 million to $1.4 million during the current fiscal year ending March 31, 2013 for employee severances and anticipate that the restructuring plan will reduce ongoing headcount expenses by approximately $8.0 million to $9.0 million annually and other additional operational expenses by $4.0 million to $5.0 million annually. We expect the restructuring program to be completed by the end of its current fiscal year ending March 31, 2013.

The restructuring charges recorded during the three and nine months ended December 31, 2011 was primarily for employee severances.

Interest and Other Income, net. The following table presents interest and other income (expense), net for the three and nine months ended December 31, 2012 and 2011 (dollars in thousands):

	Three Months Ended December 31,
	2012				2011
	Amount		% of Net Revenue		Amount		% of Net Revenue		Increase (Decrease)		% Change
Interest income (expense), net	$	892	1.7	%	$	828	1.5	%	$	64	7.7	%
Other income (expense), net	$	1,366	2.6	%	$	86	0.2	%	$	1,280	1,488.4	%

	Nine Months Ended December 31,
	2012				2011
	Amount		% of Net Revenue		Amount		% of Net Revenue		(Decrease)			% Change
Interest income (expense), net	$	3,316	2.4	%	$	3,578	2.0	%	$	(262	)	(7.3	)%
Other income (expense), net	$	1,539	1.1	%	$	209	0.1	%	$	1,330		636.4	%

Interest Income (Expense), net. Interest income, net of management fees, reflects interest earned on cash and cash equivalents, short-term investments and marketable securities. The increase in interest income, net for the three months ended December 31, 2012 as compared to the three months ended December 31, 2011 was primarily due to realized gains from the sale of short-term investments and marketable securities which was partially offset by lower interest income due to our lower cash, cash equivalents and short-term investments available-for-sale balances. The decrease in interest income, net for the nine months ended December 31, 2012, compared to the nine months ended December 31, 2011 was primarily due to our lower cash, cash equivalents and short-term investments available-for-sale balances.

Other Income (Expense) Income, net. The increase in other income for the three and nine months ended December 31, 2012 as compared to the three and nine months ended December 31, 2011 was due to a gain of $1.3 million arising from the sale of equipment and other assets.

Income Taxes. The federal statutory income tax rate was 35% for the fiscal three and nine months ended December 31, 2012 and 2011. The increase in the income tax expense recorded for the three months ended December 31, 2012 compared to December 31, 2011, was primarily related to other comprehensive income. The allocation of the current quarter tax provision included reversing $0.4 million of tax expense that was allocated to other comprehensive income in prior quarters. The decrease in the income tax expense recorded for the nine months ended December 31, 2012 compared to December 31, 2011, was also related to other comprehensive income. The allocation of the current year tax provision included a $0.1 million tax benefit in continuing operations with an offsetting tax expense in other comprehensive income.

FINANCIAL CONDITION AND LIQUIDITY

As of December 31, 2012, our principal source of liquidity consisted of $84.2 million in cash, cash equivalents and short-term investments which is approximately $1.26 per share of outstanding common stock as compared to $1.84 per share at March 31, 2012. Working capital as of December 31, 2012 was $30.4 million. Total cash, cash equivalents, and short-term investments decreased by $29.6 million during the nine months ended December 31, 2012, primarily due to cash used for operations of $30.9 million, purchase of property and equipment of $8.5 million, the repurchases of our common stock for $0.7 million, a strategic investment of $0.5 million, payment of contingent consideration of $0.5 million, issuance of a notes receivable of $0.5 million and the funding of restricted stock units withheld for taxes of $2.8 million offset by proceeds from

34

stock issuance of $5.8 million, proceeds from sale of a strategic equity investment of $7.1 million and proceeds from the sale of equipment and other assets of $1.8 million. At December 31, 2012, we had contractual obligations not included on our balance sheet totaling $90.7 million, primarily related to facility leases, IP licenses, engineering design software tool licenses, non-cancelable inventory purchase commitments and liability for uncertain tax positions.

For the nine months ended December 31, 2012, we used $30.9 million of cash in our operations compared to $3.0 million used for our operations for the nine months ended December 31, 2011. Our net loss of $116.5 million for the nine months ended December 31, 2012 included $93.4 million of non-cash charges consisting of $7.2 million of depreciation, $3.6 million of amortization of purchased intangibles, $22.8 million of stock-based compensation, $56.6 million of additional Veloce compensation cost and $4.7 million of restructuring costs offset by $1.3 million gain on asset disposals, $0.1 million relating to the tax effect on other comprehensive income and $0.1 million in acquisition related adjustment (relating to our TPack acquisition in fiscal 2011). Our net loss of $15.1 million for the nine months ended December 31, 2011 included $20.9 million of non-cash charges consisting of $6.0 million of depreciation, $5.5 million of amortization of purchased intangibles and $11.7 million of stock-based compensation, offset by a $2.3 million reduction to the estimated fair value of our contingent consideration. The remaining change in operating cash flows for the nine months ended December 31, 2012 primarily reflected decreases in accounts receivable, inventories, other assets, accounts payable and deferred revenue and increases in Veloce accrued liability, accrued payroll and related expenses and other accrued liabilities. Our overall quarterly days sales outstanding was 31 days and 50 days for the three months ended December 31, 2012 and 2011, respectively. Decrease in the revenues generated during the last month of the quarter ended December 31, 2012 as compared to the same period for the quarter ended March 31, 2012 was the primary reason for the decrease in our days sales outstanding.

We provided $17.0 million in cash from our investing activities during the nine months ended December 31, 2012, compared to using $1.2 million during the nine months ended December 31, 2011. During the nine months ended December 31, 2012, we used $8.5 million for the purchase of property and equipment, $0.5 million for purchase of strategic investment and $0.5 million for the issuance of a note receivable offset by net proceeds of $17.5 million from short-term investment activities, $7.1 million from sales of strategic equity investment and $1.8 million from the sale of equipment and other assets. During the nine months ended December 31, 2011, we generated $15.4 million for net short-term investment activities offset by $11.9 million for the purchase of property and equipment and $4.7 million for purchases of strategic investments.

We provided $1.5 million in cash for our financing activities during the nine months ended December 31, 2012, compared to using $30.0 million during the nine months ended December 31, 2011. The major financing use of cash for the nine months ended December 31, 2012 was the $0.7 million for the repurchase of common stock, $0.5 million for the payment of a contingent consideration, restricted stock units withheld for taxes of $2.8 million and other uses of cash of $0.4 million offset by proceeds from the issuance of common stock of $5.8 million. The major financing use of cash for the nine months ended December 31, 2011 was $20.9 million for the repurchase of common stock, $10.0 million for the funding of our structured stock repurchase agreements and $2.7 million for restricted stock units withheld for taxes, offset by $3.9 million in proceeds from the issuance of common stock.

Veloce Merger

On June 20, 2012 (the “Closing Date”), the Company completed its acquisition of Veloce pursuant to the terms of the Agreement and Plan of Merger, entered into as of May 17, 2009 (the “Initial Agreement”), as amended by Amendment No. 1 to Agreement and Plan of Merger, entered into as of November 8, 2010 (the “First Amendment”), and Amendment No. 2 to Agreement and Plan of Merger, entered into as of April 5, 2012 (the “Second Amendment” and, collectively with the Initial Agreement and the First Amendment, the “Merger Agreement”). The First Amendment was amended, restated and replaced in its entirety by the Second Amendment.

The terms of the Merger Agreement include the payment of initial consideration of up to $60.4 million, payable in shares of Company common stock and/or cash (at the Company's election) to holders of Veloce common stock, Veloce stock options that were vested on the Closing Date, and holders of Veloce stock equivalents (collectively, “Veloce Equity Holders”). During the three and nine months ended December 31, 2012, as part of the above arrangement, the Company issued 0.2 million shares valued at $1.1 million and 2.9 million shares valued at $16.0 million, respectively, and paid approximately $1.1 million and $15.9 million in cash, respectively. Of the $60.4 million that relates to the initial consideration, $31.9 million has been paid to date. To the extent payments of the $60.4 million are paid in the Company's common stock and relate to shares of Veloce stock that were outstanding at the date of the closing of the Merger, the value of the Company's common stock is fixed at $5.546 per share (“fixed shares”). The balance of the $60.4 million or approximately $28.5 million will be paid over multiple quarters and will include approximately 1.2 million fixed shares and at least $10.2 million in cash for a total value of $16.9 million. The remaining $11.6 million of the $28.5 million will be paid in a combination of cash and shares of the Company's common stock valued at the then-current market price.

35

For accounting purposes, the consideration payable for the acquisition of Veloce is considered compensatory and is recognized as research and development expense when incurred. Recognition of these costs will occur when the specific development and performance milestones become probable of achievement and the amount of expense will be based upon the estimated stage of product development to date. As of March 31, 2012, the first development and performance milestone set forth under the Merger Agreement was considered probable of achievement and the Company recognized $60.4 million of expense.

The total estimated value to the Veloce Equity Holders is based on the Company achieving certain performance benchmarks defined under the Merger Agreement within a certain time period. The Company performed various simulations during the three months ended December 31, 2012. The results of the simulations exceeded expectations for certain of the benchmarks defined under the Merger Agreement, and as a result the estimated maximum value to the Veloce Equity Holders was increased from approximately $135 million to the contractual maximum of $178.5 million, based on the Company's current expectations regarding the achievement of such product development milestones. As such, the total estimated value to the Veloce Equity Holders has been updated to be in the range of $117 million to $178.5 million, depending upon the achievement of multiple product development milestones and technical performance results. The increase in the estimated value to the Veloce Equity Holders also resulted in an increase of the estimated value of the first performance milestone. Research and Development expense recognized during the three months ended December 31, 2012 relating to the first performance milestone was based upon the estimated stage of the development of the first milestone as of December 31, 2012 and the estimated value tied to the first performance milestone. The remaining costs associated with the first performance milestone, estimated value of the first milestone less expense recognized through December 31, 2012, will be recognized on a straight line basis, subject to adjustment for actual progress towards the milestones, over the remaining period of expected development which is currently estimated not to exceed the next three fiscal quarters.

Additionally, during the three months ended December 31, 2012, the second development and performance milestone set forth under the Merger Agreement was considered probable of achievement. The Company recognized research and development expenses that were based upon the estimated stage of development and estimated value tied to the second performance milestone. The remaining costs associated with the second performance milestone will be recognized on a straight line basis, subject to adjustment for actual progress towards the milestones, over the remaining period of expected development which is currently estimated not to exceed the next three fiscal quarters.

The third and last development and performance milestone set forth under the Merger Agreement was not yet considered probable of achievement as of December 31, 2012.

Total research and development expenses expected to be recognized upon completion of the first and second performance milestones is approximately $142.8 million (including the initial consideration of $60.4 million), of which approximately $117 million has been recognized through December 31, 2012. During the three and nine months ended December 31, 2012, research and development expenses recognized in connection with first and second performance milestones were $51.9 million and $56.6 million, respectively. The amount and timing of expense recognition is determined based upon the probability of the respective performance milestone being achieved, the estimated progress of development, and estimated date of the milestone attainment. Timing of payments will be based upon actual attainment of the development and performance milestones, and upon vesting, if any, associated with outstanding Veloce' stock equivalents.

Of the total of approximately $142.8 million which is expected to be due to Veloce upon the attainment of the first two development and performance milestones and expected to be paid over multiple quarters, $31.9 million has been paid to date and the Company expects that approximately another $77 million will be paid in cash and stock by September 30, 2013.

Liquidity

We currently believe that our available cash, cash equivalents and short-term investments will be sufficient to meet our capital requirements and fund our operations for at least the next 12 months. We expect to satisfy the Veloce-related payment obligations using a combination of cash and the issuance of shares of common stock. We expect our resources to be sufficient to make the above described Veloce-related payments while maintaining adequate cash to run our operations. Our available liquidity could be adversely affected, however, if we decide to satisfy the Veloce liability using a greater proportion of cash rather than our common stock, or if our normal operations require us to expend more cash than currently expected. If our stock price declines, it could result in a higher dilution to our stockholders. As a result of any of the above, we could elect or be required to pursue various options to raise additional capital or generate cash. There can be no assurance that any of the options that we currently believe to be available will be viable in the future on commercially reasonable terms or at all.

Stock Repurchase Program

In August 2004, our Board of Directors authorized a stock repurchase program for the repurchase of up to $200.0 million of our common stock. Under the program, we are authorized to make purchases in the open market or enter into structured agreements. In October 2008, our Board of Directors increased the stock repurchase program by $100.0 million. During the nine months ended December 31, 2012, approximately 0.1 million shares were repurchased on the open market at a weighted average price of $5.18 per share. During the nine months ended December 31, 2011, approximately 3.5 million shares were repurchased on the open market at a weighted average price of $5.98 per share. All repurchased shares were retired upon delivery to us. As of December 31, 2012, we had $15.8 million available in our stock repurchase program.

We also utilize structured stock repurchase agreements to buy back shares which are prepaid written put options on our common stock. We pay a fixed sum of cash upon execution of each agreement in exchange for the right to receive either a pre-determined amount of cash or stock depending on the closing market price of our common stock on the expiration date of the agreement. Upon expiration of each agreement, if the closing market price of our common stock is above the pre-determined price, we will have our cash investment returned with a premium. If the closing market price is at or below the pre-determined price, we will receive the number of shares specified at the agreement inception. Any cash received, including the premium, is treated as additional paid in capital on the balance sheet.

We did not enter into any structured stock repurchase agreements during the nine months ended December 31, 2012. During the nine months ended December 31, 2011, we entered into structured stock repurchase agreements totaling $10.0 million. For those agreements that settled during the nine months ended December 31, 2011, we received 1.0 million in shares of our common stock at an effective purchase price of $9.74 per share from the settled structured stock repurchase agreements. At December 31, 2011, we had no outstanding structured stock repurchase agreements.

Other

Our aggregate fixed commitments payable over the next five years for licensing fees relating to our R&D efforts, including our licensed IP, technology, product design, test and verification tools, are approximately $27.3 million. These amounts are also included in the table below.

The following table summarizes our contractual operating leases and other purchase commitments as of December 31, 2012 (in thousands):

	Operating Leases		Other Purchase Commitments			Total
Fiscal Years Ending March 31, 2013	$	511	$	66,451	*	$	66,962
2014	1,767		12,748			14,515
2015	871		7,841			8,712
2016	278		240			518
Total minimum payments	$	3,427	$	87,280		$	90,707

* Includes liability for uncertain tax positions of $43.4 million including interest and penalties. Due to the high degree of uncertainty regarding the timing of potential future cash flows associated with these liabilities, we are unable to make a reasonably reliable estimate of the amount and period in which these liabilities might be paid.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as at December 31, 2012.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the potential loss arising from adverse changes in market rates and prices, such as foreign currency exchange rates, interest rates and a decline in the stock market. We are exposed to market risks related to changes in interest rates and foreign currency exchange rates.

We maintain an investment portfolio of various holdings, types of instruments and maturities. These securities are classified as available-for-sale and, consequently, are recorded on our consolidated balance sheets at fair value with unrealized gains or losses reported as a separate component of accumulated other comprehensive income or loss. We have established guidelines relative to diversification and maturities that attempt to maintain safety and liquidity. These guidelines are periodically reviewed and modified to take advantage of interest rate trends. We invest our excess cash in debt instruments of

37

the U.S. Treasury, corporate bonds, commercial paper, mortgage-backed and asset backed securities, and closed-end bond funds, with credit ratings as specified in our investment policy. We also have invested in preferred stocks, which pay quarterly fixed rate dividends. We generally do not utilize derivatives to hedge against increases in interest rates which decrease market values.

We are exposed to market risk as it relates to changes in the market value of our investments. At December 31, 2012, our investment portfolio included short-term securities classified as available-for-sale investments with an aggregate fair market value of $68.6 million and a cost basis of $62.5 million. Substantially all of these securities are subject to interest rate risk, as well as credit risk and liquidity risk, and will decline in value if interest rates increase or an issuer’s credit rating or financial condition is weakened.

The following table presents the hypothetical changes in fair value of our short-term investments held at December 31, 2012 (in thousands):

	Valuation of Securities Given an Interest Rate Decrease of X Basis Points (“BPS”)						Fair Value as of December 31,  2012		Valuation of Securities Given an Interest Rate Increase of X Basis Points (“BPS”)
	(150 BPS)		(100 BPS)		(50 BPS)				50 BPS		100 BPS		150 BPS
Available-for-sale investments	$	71,843	$	70,912	$	69,929	$	68,561	$	67,730	$	66,626	$	65,526

The modeling technique used measures the change in fair market value arising from selected potential changes in interest rates. Market changes reflect immediate hypothetical parallel shifts in the yield curve of plus or minus 50 basis points, 100 basis points, and 150 basis points. While this modeling technique provides a measure of our exposure to market risk, the current economic turbulence could cause interest rates to shift by more than 150 basis points.

We also invest in equity instruments of private companies for business and strategic purposes. These investments are valued based on our historical cost, less any recognized impairments. The estimated fair values are not necessarily representative of the amounts that we could realize in a current transaction.

We generally conduct business, including sales to foreign customers, in U.S. dollars, and as a result, we have limited foreign currency exchange rate risk. We did not enter into any forward currency exchange contract during the nine months ended December 31, 2012. Gains and losses on foreign currency forward contracts that are designated and effective as hedges of anticipated transactions, for which a firm commitment has been attained, are deferred and included in the basis of the transaction in the same period that the underlying transaction is settled. Gains and losses on any instruments not meeting the above criteria are recognized in income or expenses in the consolidated statements of operations in the current period.

ITEM 4. CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports we file or submit with the SEC pursuant to the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), 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 assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, a control may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

As required by Exchange Act Rule 13a-15(b), we conducted an evaluation, under the supervision and with the participation of our management, including our CEO and CFO, of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2012. Based on the foregoing, our CEO and CFO concluded that our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the most recent 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 set forth under Note 7 of Notes to Consolidated Financial Statements, included in Part I, Item 1 of this report, is incorporated herein by reference.

ITEM 1A. RISK FACTORS

Before deciding to invest in us or to maintain or increase your investment, you should carefully consider the risks described below, in addition to the other information contained in this report and in our other filings with the SEC. We update our descriptions of the risks and uncertainties facing us in our periodic reports filed with the SEC. The risks and uncertainties described below and in our other filings are not the only ones facing us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business. If any of these known or unknown risks or uncertainties actually occurs, our business, financial condition and results of operations could be seriously harmed. In that event, the market price for our common stock could decline and you may lose all or part of your investment. The risks and uncertainties set forth below with an asterisk (“*”) next to the title contain changes to the description of the risks and uncertainties associated with our business as previously disclosed in Item 1A to our Annual Report on Form 10-K for the fiscal year ended March 31, 2012 filed with the SEC on May 16, 2012.

*Our liquidity may deteriorate on our future uses of cash

Although we currently believe we have adequate liquidity to operate normally, our cash balances could decrement significantly if we decide to pay for the remainder of the Veloce acquisition consideration using a greater proportion of cash rather than our common stock, or if our normal operations require us to expend more cash. If our stock price declines, it could result in a higher dilution to our stockholders. As a result of any of the above, we may be faced with liquidity issues and could elect or be required to pursue various options to raise additional capital or generate cash. There can be no assurance that any of the options that we currently believe to be available will be viable in the future on commercially reasonable terms or at all.

During the year ended March 31, 2012 and the nine months ended December 31, 2012, our cash used in operating activities was approximately $9.4 million and $30.9 million, respectively.

*If we are unable to timely develop new products or new generations and versions of our existing products to replace our current products, our operating results and competitive position will be materially harmed.

Our industry is characterized by intense competition, rapidly evolving technology and continually changing customer requirements. These factors could render our existing products obsolete. Accordingly, our ability to compete in the future will depend in large part on our ability to identify and develop new products or new generations and versions of our existing products that achieve market acceptance on a timely and cost-effective basis, and to respond to changing requirements. If we are unable to do so, our business, operating results and financial condition will be negatively affected.

The successful development and market acceptance of our products depend on a number of factors, including, but not limited to:

• our successful collaboration with our ecosystem of partners including technology partners;

• our accurate prediction of changing customer requirements;

• timely development of new designs;

• timely qualification and certification of our products for use in electronic systems;

• continued availability on commercially reasonable terms of the manufacturing services purchased from and the technology components and tools licensed from third party suppliers;

• commercial acceptance and production of the electronic systems into which our products are incorporated;

• availability, quality, price, performance, and size of our products relative to competing products and technologies;

• our customer service and support capabilities and responsiveness;

• successful development of relationships with existing and potential new customers; and

• changes in technology and industry standards.

We have in recent years devoted substantial engineering and financial resources to designing, developing and rolling out new products and technologies and introducing several new products in our Connectivity and Computing business units. However, there can be no assurance that our product development efforts will be successful or that the products and technologies we have recently developed and which we are currently developing will achieve market acceptance. If these

39

products and technologies fail to achieve market acceptance, or if we are unable to continue developing new products and technologies that achieve market acceptance, our business, financial condition and operating results will be materially and adversely affected. In addition, for our X-Gene^™ and other server processor products, we are a licensee of the ARM v8 64-bit architecture and will depend upon the continuing timely completion and delivery by ARM of various updates and other deliverables under the license agreement. Any failure or material delay by ARM in completing its deliverables to us under the license could adversely affect our product development efforts and other planned server processor products that utilize the ARM 64-bit architecture.

*Our significant investment in Veloce may not result in the successful development of new technologies or products.

Under a merger agreement we entered into with Veloce in May 2009, as amended in November 2010 and April 2012, we agreed to acquire Veloce if certain performance milestones and delivery schedules set forth under the merger agreement are achieved. In June 2012, we completed the acquisition of Veloce upon the satisfaction of a specified FPGA product development milestone and other closing conditions. Pursuant to the merger agreement, as currently amended, the purchase price is estimated to be in the range of $117 million up to $178.5 million, depending upon the achievement and timing of multiple product development milestones and technical performance results. At this time, the eventual outcome is not determinable and as such, we are unable to provide a narrower range for the estimated total merger consideration. We will update the range in the future when additional relevant information is available.

Even after the successful completion of the acquisition of Veloce as described above, we may fail to appropriately integrate the operations of Veloce into the Company. Although we have spent considerable time and resources in the developmental effort, eventually Veloce may be unsuccessful in developing the products that are described in the merger agreement, in which case our investment in Veloce would not bear any significant value to our business and would have a material adverse impact on our financial results and condition.

We face intense competition and price pressure.

The semiconductor industry is intensely competitive. We expect competition to continue to increase as our industry and our competitors evolves and develop.

Many of our competitors have longer operating histories and presences in key markets, greater name recognition, larger customer bases, and significantly greater financial, sales and marketing, manufacturing, distribution, technical and other resources than we do, and in some cases operate their own fabrication facilities. These competitors may be able to adapt more quickly to new or emerging technologies and changes in customer requirements. They may also be able to devote greater resources to the promotion and sale of their products. We also face competition from newly established competitors, suppliers of products, and customers who choose to develop their own semiconductor solutions.

Existing or new competitors may develop technologies that more effectively address our markets with products that offer enhanced features and functionality, lower power requirements, greater levels of integration or lower cost. Increased competition also has resulted in and is likely to continue to result in increased expenditures on research and development, declining average selling prices, reduced gross margins and loss of market share in certain markets. These factors in turn create increased pressure to consolidate. We cannot assure you that we will be able to continue to compete successfully against current or new competitors. If we do not compete successfully, we may lose market share in our existing markets and our revenues may fail to increase or may decline.

We and our customers face intense price pressure from competition from companies in lower cost countries like China. In response to these price pressures, our customers could require us to reduce prices which could impact our financial results adversely. These price pressures could cause our customers and us to not be competitive and lose significant revenues. Furthermore, our discrete legacy products are being and could continue to be integrated into ASICs that could cause our revenues from such products to decline at a faster rate.

*Our dependence on third-party manufacturing and supply relationships increases the risk that we will not have an adequate supply of products to meet demand or that our cost of materials will be higher than expected.

We depend upon third parties to manufacture, assemble, package or test certain of our products. As a result, we are subject to risks associated with these third parties, including:

• noncompetitive pricing of foundry services;

• reduced control over delivery schedules and quality;

• inadequate manufacturing yields and excessive costs;

• the risks associated with transitioning our manufacturing supply from one foundry to another;

• our ability to attract and retain key personnel and to maintain knowledge base;

40

• difficulties selecting and integrating new subcontractors;

• the potential lack of adequate capacity at the foundry during periods of excess demand, resulting in significant increases in lead-time requirements and production delays;

• increased risk of excess and obsolete inventory charges due to the higher level of inventories in response to the increased lead-times;

• limited warranties on products supplied to us;

• potential increases in prices;

• potential instability and business disruption in countries where third-party manufacturers are located;

• potential misappropriation of our intellectual property; and

• potential foundry shortages when we commence manufacturing future products, especially those with 28nm technologies which could delay the supply of products to our customers.

Our outside foundries generally manufacture our products on a purchase order basis, and we have few long-term supply arrangements with these suppliers. We have less control over delivery schedules, manufacturing yields and costs than our competitors that use their own fabrication facilities or provide larger volumes of business to their outside foundries. A manufacturing disruption or capacity constraint experienced by one or more of our outside foundries or a disruption of our relationship with an outside foundry, including discontinuance of our products by that foundry, would negatively impact the production of certain of our products for a substantial period of time.

As our third-party manufacturing suppliers extend their lead time requirements, we will likely need to also extend our lead time requirements to our customers. This could cause our customers to lower their competitive assessment of us as a supplier and, as a result, we may not be considered for future design awards.

Our IC products are generally only qualified for production at a single foundry. These suppliers can allocate, and in the past have allocated, capacity to the production of other companies’ products while reducing deliveries to us on short notice. There is also the potential that they may discontinue manufacturing our products or go out of business. Because establishing relationships, designing or redesigning ICs, and ramping production with new outside foundries may take over a year, there is no readily available alternative source of supply for these products.

Difficulties associated with adapting our technology and product design to the proprietary process technology and design rules of outside foundries can lead to reduced yields of our IC products. This risk is substantially higher with respect to the anticipated manufacture of our new X-Gene products at 40 nanometers and potentially smaller geometries. The process technology of an outside foundry is typically proprietary to the manufacturer. Since low yields may result from either design or process technology failures, yield problems may not be effectively determined or resolved until an actual product exists that can be analyzed and tested to identify process sensitivities relating to the design rules that are used. As a result, yield problems may not be identified until well into the production process, and resolution of yield problems may require cooperation between us and our manufacturer. This risk could be compounded by the offshore location of certain of our manufacturers, increasing the effort and time required to identify, communicate and resolve manufacturing yield problems. Manufacturing defects that we do not discover during the manufacturing or testing process may lead to costly product recalls. These risks may lead to increased costs or delayed product delivery, which would harm our profitability and customer relationships.

If the foundries or subcontractors we use to manufacture our products discontinue the manufacturing processes needed to meet our demands, or fail to upgrade their technologies needed to manufacture our products, we may be unable to deliver products to our customers, which could materially adversely affect our operating results and harm our reputation. The transition to the next generation of manufacturing technologies at one or more of our outside foundries could be unsuccessful or delayed.

Our requirements typically represent a very small portion of the total production of the third-party foundries. As a result, we are subject to the risk that a producer will cease production of an older or lower-volume process that it uses to produce our parts or raise the prices it charges us. We cannot assure you that our external foundries will continue to devote resources to the production of parts for our products or continue to advance the process design technologies on which the manufacturing of our products are based. Each of these events could increase our costs, lower our gross margin, cause us to hold more inventories or materially impact our ability to deliver our products on time. As our volumes decrease with any third-party foundry, the likelihood of unfavorable pricing increases.

Some companies that supply our customers are similarly dependent on a limited number of suppliers to produce their products. These other companies’ products may be designed into the same networking equipment into which our products are designed. Our order levels could be reduced materially if these companies are unable to access sufficient production capacity to produce in volumes demanded by our customers because our customers may be forced to slow down or halt production on the equipment into which our products are designed.

41

*Our restructuring activities could result in management distractions, operational disruptions and other difficulties.

Over the past several years, we have initiated several restructuring activities in an effort to reduce operating costs and such restructuring activities are likely to continue. In particular, in December 2012, we commenced a Board-approved restructuring plan that currently is anticipated to result in an aggregate reduction in force of approximately 10% of our employee headcount. Employees whose positions were or are eliminated in connection with these restructuring activities may seek employment with our competitors, customers or suppliers. Although each of our employees is required to sign a confidentiality agreement with us at the time of hire, which agreement contains covenants prohibiting among other things the disclosure or use of our confidential information and the solicitation of our employees, we cannot guarantee that the confidential nature of our proprietary information will be maintained in the course of such future employment, or that our key continuing employees will not be solicited to terminate their employment with us. Any additional restructuring efforts could divert the attention of our management away from our operations, harm our reputation, increase our expenses, increase the work load placed upon remaining employees and cause our remaining employees to lose confidence in the future performance of the Company and decide to leave. We cannot guarantee that any additional restructuring activities undertaken in future restructuring activities will be successful, or that we will be able to realize the cost savings and other anticipated benefits from our previous, current or future restructuring plans. In addition, if we continue to reduce our workforce, it may adversely impact our ability to respond rapidly to new growth opportunities.

*Natural disasters in certain regions, such as the Eastern United States, Japan and Thailand, could adversely affect our manufacturing and supply chain which, in turn, could have a material adverse effect on our business, our results of operations and our financial condition.

The occurrence of natural disasters in certain regions, such as the hurricane Sandy in the Northeast United States, earthquake and tsunami in Japan and flooding in Thailand, could negatively impact our manufacturing and supply chain, our ability to deliver products, on a timely basis or at all, to our customers, the cost of our products, and the demand for our products. The occurrence of natural disasters could also cause delays in our customers’ supply chains, causing them to delay their requirements for our products until they resolve shortages from their other suppliers. Any such occurrences of natural disasters could have a material adverse effect on our business, our results of operations and our financial condition.

*We may experience difficulties in transitioning to smaller geometry processes or in achieving higher levels of design integration and, as a result, may experience reduced manufacturing yields, delays in product deliveries and increased expenses.

Currently, we anticipate introducing our X-Gene 40 nanometer product and we have a 28nm version of the product under development. As smaller line width geometry processes become more prevalent, we expect to integrate greater levels of functionality into our IC products and to transition our IC products to increasingly smaller geometries. This transition will require us to redesign certain products and will require us and our foundries to migrate to new manufacturing processes for our products.

We may not be able to achieve higher levels of design integration or deliver new integrated products on a timely basis. We periodically evaluate the benefits, on a product-by-product basis, of migrating to smaller geometry process technologies to reduce our costs and increase performance, and we have designed IC products to be manufactured at 40 nanometer and potentially smaller geometry processes. We have experienced some difficulties in shifting to smaller geometry process technologies and new manufacturing processes. These difficulties resulted in reduced manufacturing yields, delays in product deliveries and increased expenses. The transition to smaller geometries is inherently more expensive and as we manufacture more products using smaller geometries, the incremental costs could have an adverse impact on our earnings. We may face similar difficulties, delays and expenses as we continue to transition our IC products to smaller geometry processes. We are dependent on our relationships with our foundries to transition to smaller geometry processes successfully. We cannot assure you that our foundries will be able to effectively manage the transition or that we will be able to maintain our relationships with our foundries. If we or our foundries experience significant delays in this transition or fail to implement this transition, our business, financial condition and results of operations could be materially and adversely affected.

The gross margins for our products could decrease rapidly or not increase as forecasted, which will negatively impact our business, financial conditions and results of operations.

The gross margins for our solutions have historically declined over time. Factors that we expect to cause downward pressure on the gross margins for our products include competitive pricing pressures, the cost sensitivity of our customers, particularly in the higher-volume markets, new product introductions by us or our competitors, the overall mix of our products sold during a particular quarter, and other factors. From time to time, for strategic reasons, we may accept orders at less than optimal gross margins in order to facilitate the introduction of new products or the market penetration of existing products. To maintain acceptable operating results, we will need to offset any reduction in gross margins of our products by reducing costs, increasing sales volume, developing and introducing new products and developing new generations and versions of existing

42

products on a timely basis. If the gross margins for our products decline or not increase as anticipated and we are unable to offset those reductions, our business, financial condition and results of operations will be materially and adversely affected.

*The current economic circumstances and uncertain political conditions could harm our revenues, operating results and financial condition.

The economies of the United States and other developed or developing countries appear to be slowly emerging from an economic downturn. We cannot predict whether this economic recovery will continue or reverse course. Deteriorating economic conditions in certain countries (such as in Europe) could adversely spiral and impact the global nascent recovery which could in-turn adversely impact our revenues and financial results and condition.

The recent downturn resulted in a decline in our near term revenues and it will take some time for our near-term revenues to return to their previous levels. Our current operating plans are based on assumptions concerning levels of consumer and corporate spending. If weak global and domestic economic and market conditions persist or deteriorate, we may experience further material impacts on our business, operating results and financial condition which could result in a decline in the price of our common stock. If economic conditions worsen, we may have to implement additional cost reduction measures or delay certain R&D spending, which may adversely impact our ability to introduce new products and technologies.

We maintain an investment portfolio of various holdings, types of instruments and maturities. These securities are generally classified as available-for-sale and, consequently, are recorded on our consolidated balance sheets at fair value with unrealized gains or losses reported as a separate component of accumulated other comprehensive (loss) income. Our portfolio primarily includes fixed income securities, mutual funds and preferred stock, the values of which are subject to market price volatility. The deterioration of these market prices has had an unfavorable impact on our portfolio and has caused us to record impairment charges to our earnings. During the fiscal years ended March 31, 2012 and 2011, and for the three and nine months ended December 31, 2012, we did not record any other-than-temporary impairment charges while during the fiscal year ended March, 31 2010 we recorded other-than-temporary impairment charges of $4.1 million. If market prices continue to decline or securities continue to be in a loss position over time, we may recognize additional impairments in the fair value of our investments.

Adverse economic and market conditions could also harm our business by negatively affecting the parties with whom we do business, including our business partners, our customers and our suppliers. These conditions could impair the ability of our customers to pay for products they have purchased from us. As a result, allowances for doubtful accounts and write-offs of accounts receivable from our customers may increase. In addition, our suppliers may experience financial difficulties that could negatively affect their operations and their ability to supply us with the parts we need to manufacture our products.

Our product sales are concentrated among a few large customers. Based on direct shipments, net revenues to customers that were equal to or greater than 10% of total net revenues were as follows (in thousands):

	Three Months Ended				Nine Months Ended
	December 31,				December 31,
	2012		2011		2012		2011
Wintec (global logistics provider)	21	%	19	%	20	%	21	%
Avnet (distributor)	27	%	23	%	28	%	19	%
Flextronics (sub-contract manufacturer)	*		*		*		11	%

Less than 10% of total net revenues.

We expect that our largest customers will continue to account for a substantial portion of our net revenue for the foreseeable future. Adverse economic and market conditions affecting these customers could adversely affect our financial operations and results.

We have invested, and will continue to invest, in privately-held companies, most of which can still be considered to be in startup or developmental stages. These investments are inherently risky as the market for the technologies or products they have under development are typically in the early stages and may never materialize. We could lose all or substantially all of the value of our investments in these companies and, in some cases, we have lost all or substantially all of the value of our investment in such entities.

43

*Our operating results may fluctuate because of a number of factors, many of which are beyond our control.

If our operating results are below the expectations of research analysts or investors, then the market price of our common stock could decline. Some of the factors that affect our quarterly and annual results, but which are difficult to control or predict, are:

• communications, information technology and semiconductor industry conditions;

• fluctuations in the timing and amount of customer requests for product shipments;

• the reduction, rescheduling or cancellation of orders by customers, including as a result of slowing demand for our products or our customers’ products or over-ordering or double booking of our products or our customers’ products;

• changes in the mix of products that our customers buy;

• the gain or loss of one or more key customers or their key customers, or significant changes in the financial condition of one or more of our key customers or their key customers;

• our ability to introduce, certify and deliver new products and technologies, including without limitation our X-Gene products, on a timely basis;

• the announcement or introduction of new products and technologies by our competitors;

• competitive pressures on selling prices;

• the ability of our customers to obtain components from their other suppliers;

• market acceptance of our products and our customers’ products;

• fluctuations in manufacturing output, yields or other problems or delays in the fabrication, assembly, testing or delivery of our products or our customers’ products;

• disasters that could affect our supply chain or our customers supply chain;

• increases in the costs of products or discontinuance of products by our suppliers;

• the availability of external foundry capacity, contract manufacturing services, purchased parts and raw materials including packaging substrates;

• the availability of package and test vendor capacity;

• problems or delays that we and our foundries may face in shifting the design and manufacture of our future generations of IC products to smaller geometry process technologies and in achieving higher levels of design and device integration;

• the amounts and timing of meeting the specifications and expense recovery on non-recurring engineering projects;

• the amounts and timing of costs associated with warranties and product returns;

• the amounts and timing of investments in R&D;

• the product lifecycle and recoverability of capitalized architectural licenses, technology access fees and mask sets;

• the amounts and timing of the costs associated with payroll taxes related to stock option exercises or settlement of restricted stock units;

• costs associated with acquisitions and the integration of acquired companies, products and technologies;

• the impact of potential one-time charges related to purchased intangibles;

• our ability to successfully integrate acquired companies, products and technologies;

• the impact on interest income of a significant use of our cash for an acquisition, stock repurchase or other purpose;

• the effects of changes in interest rates or credit worthiness on the value and yield of our short-term investment portfolio;

• costs associated with compliance with applicable environmental, other governmental or industry regulations including costs to redesign products to comply with those regulations or lost revenue due to failure to comply in a timely manner;

• the effects of changes in accounting standards;

• costs associated with litigation, including without limitation, attorney fees, litigation judgments or settlements, relating to the use or ownership of intellectual property or other claims arising out of our operations;

• our ability to identify, hire and retain senior management and other key personnel;

• the effects of war, acts of terrorism or global threats, such as disruptions in general economic activity and changes in logistics and security arrangements;

• the availability of ecosystem partners; and

• global economic and industry conditions.

*Our business, financial condition and operating results would be harmed if we do not achieve anticipated revenues.

We can have revenue shortfalls for a variety of reasons, including:

• shortages of raw materials or production capacity constraints that lead our suppliers to allocate available supplies or capacity to their other customers, which may disrupt our ability to meet our production obligations;

• our customers may experience shortages from their suppliers that may cause them to delay orders or deliveries of our products;

• delays in the availability of our products or our customers’ products;

44

• delays in the availability of the software elements from third party vendors and ecosystem partners that may cause delays in customers using our hardware products resulting in further delays of bringing our product to market;

• the reduction, rescheduling or cancellation of customer orders;

• declines in the average selling prices of our products;

• delays when our customers are transitioning from old products to new products;

• a decrease in demand for our products or our customers’ products;

• a decline in the financial condition or liquidity of our customers or their customers;

• the failure of our products to be qualified in our customers’ systems or certified by our customers;

• excess inventory of our products held by our customers, resulting in a reduction in their order patterns as they work through the excess inventory of our products;

• fabrication, test, product yield, or assembly constraints for our products that adversely affect our ability to meet our production obligations;

• the failure of one or more of our subcontract manufacturers to perform its obligations to us;

• our failure to successfully integrate acquired companies, products and technologies; and

• global economic and industry conditions.

Our business is characterized by short-term orders and shipment schedules. Customer orders typically can be cancelled or rescheduled without significant penalty to the customer. Because we do not have substantial non-cancellable backlog, we typically plan our production and inventory levels based on internal forecasts of customer demand, which is highly unpredictable and can fluctuate substantially. Customer orders for our products typically have non-standard lead times, which make it difficult for us to predict revenues and plan inventory levels and production schedules. If we are unable to plan inventory levels and production schedules effectively, our business, financial condition and operating results could be materially and adversely affected.

From time to time, in response to anticipated long lead times to obtain inventory and materials from our outside contract manufacturers, suppliers and foundries, we may order materials in advance of anticipated customer demand. This advance ordering has in the past resulted and may in the future result in excess inventory levels or unanticipated inventory write-downs if expected orders fail to materialize, or other factors render our products less marketable. If we are forced to hold excess inventory or we incur unanticipated inventory write-downs, our financial condition and operating results could be materially and adversely affected.

Our expense levels are relatively fixed in the short-term and are based on our expectations of future revenues. We have limited ability to reduce expenses quickly in response to any revenue shortfalls. Changes to production volumes and impact of overhead absorption may result in a decline in our financial condition or liquidity.

*Our business is dependent on the pace of recovery of the communications industry.

There can be no assurance that the recent slowdown in the adoption of technology, including without limitation optical transport network (OTN) technology, in our Connectivity business will reverse itself the near future. It is possible that any reversal of the slowdown will take longer than previously anticipated, or that our estimated market share in the Connectivity space is in fact much lower than we anticipate. Also, our product sales are concentrated among a few large customers. Adverse economic and market conditions affecting these customers could adversely affect our financial operations and results.

We are continuing to focus our current connectivity investments on high growth 10G and faster Ethernet solutions, data center, OTN and enterprise market opportunities while continuing to service the Telecom (SONET/SDH) market. Over time, we believe customers will transition from the SONET/SDH standard to higher speed, lower power products that utilize the OTN standard in order to support the increasing demand for transmission of data over networks. However, the timing and extent of this transition is uncertain due to the significant investment that is needed to convert networks to the OTN standard. As such, the rate of conversion to the OTN standard is, in part, greatly influenced by global economic market conditions. Recessionary type market conditions will result in a slower transition of networks to the OTN standard. Additionally, there can be no assurance that our revenues will increase as the OTN standard is adopted.

Interruptions, delays, security breaches or other unauthorized activities at third-party data centers or other Cloud Computing infrastructure providers could materially harm our business.

We conduct significant business functions and computer operations, including without limitation data storage and email, using the infrastructure systems of third-party vendors, such as remote data centers, virtual servers and other “cloud computing” resources. “Cloud computing” is an information technology hosting and delivery system in which data is stored outside of the user’s physical infrastructure and is delivered to and used by the user as an internet-based application service. These third-party systems may experience cyber-attacks and other security breaches, along with the possible risk of loss, theft or unauthorized publication of our technical, proprietary and trade secret information or other confidential information of our

45

employees and customers. Any interruptions or problems at such data centers or other cloud computing facilities could result in significant disruptions to our business operations hosted at or affected by such site. We do not control the operation of such data center or other providers, and each is vulnerable to damage or interruption from earthquakes, floods, fires, vandalism, power loss, telecommunications failures and similar events. These third-party vendor relationships present further risk management challenges for us, including, among others: confirming and monitoring the third-party’s security measures; the potential for improper handling of or access to our data; and data location uncertainty, including the possibility of data storage in inappropriate jurisdictions, where laws or security measures may be inadequate, or the unauthorized movement of technical data between locations in violation of applicable export laws. We undertake substantial efforts to assure the security and confidentiality of information provided to our vendors under cloud computing or other arrangements through appropriate risk evaluation, security and financial due diligence, contracts designed to set and maintain high security and confidentiality standards, and ongoing evaluation of third-party compliance with the required standards. While we expend significant resources on these measures, there can be no assurance that we will be successful in preventing attacks, breaches or other unauthorized activities or detecting and stopping them once they have begun. Our failure to effectively manage and communicate our strategies with our outsourced service providers, or their failure to perform as required or to properly protect our data, may result in operational difficulties which may adversely affect our business, financial condition and results of operations. In addition, such data center and other providers have no obligation to renew their agreements with us on commercially reasonable terms, or at all. If we are unable to renew our agreements with the data center and other providers on commercially reasonable terms, we may experience costs or down time in connection with the transfer to new third-party providers.

We are dependent on orders that are received and shipped in the same quarter and are therefore limited in our visibility of future product shipments.

Our net sales in any given quarter depend upon a combination of shipments from backlog and orders received in that quarter for shipment in that quarter, which we refer to as turns business. We measure turns business at the beginning of a quarter based on the orders needed to meet the shipment forecasts that we set entering the quarter. Historically, we have relied on our ability to respond quickly to customer orders as part of our competitive strategy, resulting in customers placing orders with relatively short delivery schedules. Shorter lead times generally mean that turns orders as a percentage of our business are relatively high in any particular quarter and reduce our backlog visibility on future product shipments. Turns business correlate to overall semiconductor industry conditions and product lead times. Because turns business is difficult to predict, varying levels of turns business make our net sales more difficult to forecast. If we do not achieve a sufficient level of turns business in a particular quarter relative to our revenue forecasts, our revenue and operation results may suffer.

*Our business is dependent on selling to distributors.

Sales to distributors accounted for approximately 64% and 65% of our revenues for three and nine months ended December 31, 2012 and 65% and 57%, respectively, for the three and nine months ended December 31, 2011. Our largest distributor accounted for approximately 27% and 28% of our revenues for three and nine months ended December 31, 2012 and 23% and 19%, respectively, for the three and nine months ended December 31, 2011. We do not have long-term agreements with our distributors and either party can terminate the relationship with little advance notice.

Any future adverse conditions in the U.S. and global economies or in the U.S. and global credit markets could materially impact the operations of our distributors. Any deterioration in the financial condition of our distributors or any disruption in the operations of our distributors could adversely impact the flow of our products to our end customers and adversely impact our results of operations. In addition, during an industry or economic downturn, it is possible there will be an oversupply of products and a decrease in sell-through of our products by our distributors which could cause them to hold excess inventories and reduce our net sales in a given period and result in an increase in stock rotations.

*Our business substantially depends upon the continued growth of the technology sector and the Internet.

The technology equipment industry is cyclical and has in the past experienced significant and extended downturns. The recent downturn was significant and we cannot predict if the current improvement is sustainable in the near future. A substantial portion of our business and revenue depends on the continued growth of the technology sector and the Internet. We sell our communications IC products primarily to communications equipment manufacturers that in turn sell their equipment to customers that depend on the growth of the Internet. The past downturn has caused a reduction in capital spending on information technology. While we are beginning to see indications of improvement, there are no guarantees that this growth will sustain, resulting in potential volatility. If there is another downturn, our business, operating results and financial condition may be materially and adversely affected. We are developing products for the cloud server market which is currently dominated by a few large customers. If we are unable to partner with and sell our products to these customers, our future revenues from these products may be adversely impacted.

46

*The loss of one or more key customers, the diminished demand for our products from a key customer, or the failure to obtain certifications from a key customer or its distribution channel could significantly reduce our revenues and profits.

A relatively small number of customers have accounted for a significant portion of our revenues in any particular period. We have no long-term volume purchase commitments from our key customers. One or more of our key customers may discontinue operations as a result of consolidation, bankruptcy or otherwise. Reductions, delays and cancellation of orders from our key customers or the loss of one or more key customers could significantly reduce our revenues and profits. We cannot assure you that our current customers will continue to place orders with us, that orders by existing customers will continue at current or historical levels or that we will be able to obtain orders from new customers.

Our ability to maintain or increase sales to key customers and attract significant new customers is subject to a variety of factors, including:

• supply constraints and manufacturing delays by our outside foundries may result in significantly reduced volumes and delayed deliveries of our products;

• customers may stop incorporating our products into their own products with limited notice to us and may suffer little or no penalty as a result of such action;

• customers or prospective customers may not incorporate our products into their future product designs;

• design wins (as explained below) with customers or prospective customers may not result in sales to such customers;

• the introduction of new products by customers may occur later or be less successful in the market than planned;

• some of our customers may reduce or eliminate future purchase orders or design wins placed with us as an adverse reaction to our having sold patents to third parties that thereafter asserted the acquired patents in infringement actions brought against such customers;

• we may successfully design a product to customer specifications but the customer may not be successful in the market;

• sales of customer product lines incorporating our products may rapidly decline or such product lines may be phased out;

• our agreements with customers typically are non-exclusive and do not require them to purchase a minimum quantity of our products;

• many of our customers have pre-existing relationships or may establish relationships with our current or potential competitors that may cause our customers to switch from using our products to using competing products;

• some of our OEM customers may develop products internally that would replace our products;

• we may not be able to successfully develop relationships with additional network equipment vendors;

• our relationships with some of our larger customers may deter other potential customers (who compete with these customers) from buying our products;

• the impact of terminating certain sales representatives or sales personnel as a result of a Company workforce reduction or otherwise; and

• some of our customers and prospective customers may become less viable or fail.

The occurrence of any one of the factors above could have a material adverse effect on our business, financial condition and results of operations.

There is no guarantee that design wins will become actual orders and sales.

A “design win” occurs when a customer or prospective customer notifies us that our product has been selected to be integrated with the customer’s product. There can be delays of several months or more between the design win and when a customer initiates actual orders of our product. Following a design win, we will commit significant resources to the integration of our product into the customer’s product before receiving the initial order. Receipt of an initial order from a customer following a design win, however, is dependent on a number of factors, including the success of the customer’s product, and cannot be guaranteed. The design win may never result in an actual order or sale of our products.

Any significant order cancellations or order deferrals could cause unplanned inventory growth resulting in excess inventory, which may adversely affect our operating results.

Our customers may increase orders during periods of product shortages or cancel orders if their inventories are too high. Major inventory corrections by our customers are not uncommon and can last for significant periods of time and affect demand for our products. Customers may also cancel or delay orders in anticipation of new products or for other reasons. Cancellations or deferrals could cause us to hold excess inventory, which could reduce our profit margins by reducing sales prices, incurring inventory write-downs or writing off additional obsolete products.

47

The book-to-bill ratio is commonly used by investors to compare and evaluate technology and semiconductor companies. The book-to-bill ratio is a demand-to-supply ratio that compares the total amount of orders received to the total amount of orders filled. This ratio tells whether the Company has more orders than it delivered (if greater than 1), has the same amount of orders that it delivered (equals 1), or has less orders than it delivered (under 1). Though the ratio provides an indicator of whether orders are rising or falling, it does not consider the timing of, or if the order will result in future revenues and the effect of changing lead times on bookings. As lead times increase, customers will place orders sooner, therefore increasing our bookings and book-to-bill ratio.

The increasing lead times from our suppliers cause us to make commitments for inventory purchases earlier in our production cycle which in turn increases our risk of having excess inventory. In addition, some of our suppliers are delivering based on allocations which in turn cause us to increase our inventory levels. We must balance our inventory levels between the risk of losing a significant customer to a competitor because we cannot meet our customer’s requirements and the risk of having excess inventory if a significant order is cancelled.

Inventory fluctuations could affect our results of operations and restrict our ability to fund our operations. Inventory management remains an area of focus as we balance the need to maintain strategic inventory levels to ensure competitive lead times, meet customer expectations and guard against the risk of inventory obsolescence because of changing technology and customer requirements.

We generally recognize revenue upon shipment of products to a customer. If a customer refuses to accept shipped products or does not pay for these products, we could miss future revenue projections or incur significant charges against our income, which could materially and adversely affect our operating results.

Our customers’ products typically have lengthy design cycles. A customer may decide to cancel or change its product plans, which could cause us to lose anticipated sales.

After we have developed and delivered a product to a customer, the customer will usually test and evaluate our product prior to designing its own equipment to incorporate our product. Our customers may need more than six months to test, evaluate and adopt our product and an additional nine months or more to begin volume production of the equipment or devices that incorporate our product. Due to this generally lengthy design cycle, we may experience significant delays from the time we increase our operating expenses and make investments in inventory until the time that we generate revenue from these products. It is possible that we may never generate any revenue from these products after incurring such expenditures. Even if a customer selects our product to incorporate into its equipment, we cannot guarantee that the customer will ultimately market and sell its equipment or devices that such efforts by our customer will be successful. The delays inherent in this lengthy design cycle increases the risk that a customer will decide to cancel or change its product plans. Such a cancellation or change in plans by a customer could cause us to lose sales that we had anticipated. While our customers’ design cycles are typically long, some of our product life cycles tend to be short as a result of the rapidly changing technology environment in which we operate. As a result, the resources devoted to R&D, product sales and marketing may not generate material revenue for us, and from time to time, we may need to write off excess and obsolete inventory. If we incur significant R&D and marketing expenses and investments in inventory in the future that we are not able to recover, and we are not able to mitigate those expenses, our operating results could be adversely affected. In addition, if we sell our products at reduced prices in anticipation of cost reductions but still hold higher cost products in inventory, our operating results would be harmed.

*An important part of our strategy is to focus on Data Center markets. If we change strategy or are unable to further expand our share of these markets or react timely or properly to emerging trends, our revenues may not grow and could decline.

Our markets frequently undergo transitions in which products rapidly incorporate new features and performance standards on an industry-wide basis. If our products are unable to support the new features or performance levels required by OEMs in these markets, or if our products fail to be certified by OEMs, we will lose business from an existing or potential customer and may not have the opportunity to compete for new design wins or certification until the next product transition occurs. If we fail to develop products with required features or performance standards, or if we experience a delay as short as a few months in certifying or bringing a new product to market, or if our customers fail to achieve market acceptance of their products, our revenues could be significantly reduced for a substantial period.

We expect a significant portion of our revenues to continue to be derived from sales of products based on current, widely accepted transmission standards. If the communications market evolves to new standards, we may not be able to successfully design and manufacture new products that address the needs of our customers or gain substantial market acceptance.

If we do not identify and pursue the correct emerging trends and align ourselves with the correct market leaders, we may not be successful and our business, financial condition and results of operations could be materially and adversely affected.

48

Customers for our products generally have substantial technological capabilities and financial resources. Some customers have traditionally used these resources to internally develop their own products. The future prospects for our products in these markets are dependent upon our customers’ acceptance of our products as an alternative to their internally developed products. Future sales prospects also are dependent upon acceptance of third-party sourcing for products as an alternative to in-house development. Network equipment vendors may in the future continue to use internally developed components. They also may decide to develop or acquire components, technologies or products that are similar to, or that may be substituted for, our products.

If our network equipment vendor customers fail to accept our products as an alternative, if they develop or acquire the technology to develop such components internally rather than purchase our products, or if we are otherwise unable to develop or maintain strong relationships with them, our business, financial condition and results of operations would be materially and adversely affected.

*Our business strategy contemplates the potential acquisition of other companies, products and technologies. Merger and acquisition activities involve numerous risks and we may not be able to address these risks successfully without substantial expense, delay or other operational or financial problems that could disrupt our business and harm our results of operations and financial condition.

Acquiring products, technologies or businesses from third parties, making equity investments in companies developing such products, technologies or businesses, and making additional investments in companies in which we already have an interest are all part of our long-term business strategy. The risks involved with merger and acquisition and equity investment activities include:

• diversion of management’s attention from our core businesses;

• failure to integrate or potential loss of key employees, particularly those of the acquired companies;

• difficulty in completing an acquired company’s in-process research or development projects;

• customer dissatisfaction or performance problems with an acquired company’s products or services;

• adverse effects on existing business relationships with suppliers and customers;

• costs associated with acquisitions, mergers or investments;

• difficulties associated with combining or integrating acquired companies, purchased operations, products or technologies;

• difficulties and risks associated with entering and competing in markets that are unfamiliar to us; and

• ability of the acquired companies to meet their financial projections.

In addition, in the event of any such investments, mergers or acquisitions, we could;

• issue stock that would dilute, in some cases significantly, our current stockholders’ percentage ownership;

• use a significant portion of our cash reserves or incur debt;

• assume liabilities, including unknown liabilities or other unanticipated costs, events or circumstances;

• incur amortization or impairment expenses related to goodwill and other intangible assets and deferred compensation; and

• incur large and immediate write-offs.

Any of these risks could materially harm our business, financial condition and results of operations.

As with past acquisitions, future acquisitions could adversely affect operating results. In particular, acquisitions may materially and adversely affect our results of operations because they may require large one-time charges or could result in increased debt or contingent liabilities, unanticipated third-party litigation, adverse tax consequences, substantial additional depreciation or deferred compensation charges. Our past purchase acquisitions required us to capitalize significant amounts of goodwill and purchased intangible assets. As a result of the slowdown in our industry and reduction of our market capitalization, we have been required to record significant impairment charges against these assets as noted in our previous financial statements. These market conditions continuously change and it is difficult to project how long these current uncertain economic conditions may last. These conditions have caused a decline in our near term revenues and it will take some time to ramp back up to our previous levels, if at all. Additionally, market values had deteriorated, which had an unfavorable impact on our valuations which are part of the goodwill and purchased intangible asset impairment tests. There can be no assurances that market conditions will not deteriorate further or that our market capitalization will not decline further. At December 31, 2012, we had $26.2 million of goodwill and purchased intangible assets. We cannot assure you that we will not be required to take significant charges as a result of impairment to the carrying value of the purchased intangible assets, due to further adverse changes in market conditions.

In September 2010, we completed the acquisition of TPack for $32 million in cash, exclusive of $0.5 million cash acquired. In conjunction with the acquisition, we recorded $23.7 million in amortizable intangible assets and $13.2 million in goodwill. In January 2011, TPack’s primary supplier of FPGAs announced it had acquired a competitor of TPack. This supplier

49

will continue to provide FPGAs for TPack’s current products and products currently under development, but not for any future products. While we were negotiating with another supplier of FPGAs, they too acquired a competitor of TPack in March 2011. The increased competition from these synergistic acquisitions could adversely affect the future revenue streams from TPack as we implement a library strategy where customers can choose either FPGA supplier. The financial forecasts and other assumptions used to evaluate the acquisition that is included as part of the overall reporting unit may not materialize as expected.

In June 2012, the Company acquired Veloce for an initial consideration of $60.4 million with potential additional consideration based upon actual technical performance results. Pursuant to the merger agreement, as currently amended, the purchase price is estimated to be in the range of $117 million up to $178.5 million, depending upon the achievement and timing of multiple product development milestones and technical performance results. At this time, the eventual outcome is not determinable and as such, we are unable to provide a narrower range for the estimated total merger consideration. We will update the range in the future when additional relevant information is available.

Our industry and markets are subject to consolidation, which may result in stronger competitors, fewer customers and reduced demand.

There has been industry consolidation among communications IC companies, network equipment companies and telecommunications companies in the past, such as the acquisition of Seamicro Inc. by Advanced Micro Devices in February 2012, Netlogic Microsystems, Inc. by Broadcom Corporation in February 2012 and Gennum Corporation by Semtech Corporation in March 2012. We expect this consolidation to continue as companies attempt to strengthen or hold their positions in evolving markets. Consolidation may result in stronger competitors, fewer customers and reduced demand, which in turn could have a material adverse effect on our business, operating results, and financial condition.

Our operating results are subject to fluctuations because we rely heavily on international sales.

International sales account for a significant part of our revenues and may account for an increasing portion of our future revenues. The revenues we derive from international sales may be subject to certain risks, including:

• foreign currency exchange fluctuations;

• changes in regulatory requirements;

• tariffs, rising protectionism and other barriers;

• timing and availability of export licenses;

• political and economic instability;

• natural disasters;

• increased exposure to liability under U.S and foreign anti-corruption laws and regulations;

• difficulties in staffing and managing foreign operations;

• difficulties in managing distributors;

• difficulties in obtaining governmental and export approvals for communications, processors and other products;

• reduced or uncertain protection for intellectual property rights in some countries;

• longer payment cycles and difficulties in collecting accounts receivable in some countries;

• burdens of complying with a wide variety of complex foreign laws and treaties;

• potentially adverse tax consequences; and

• an uncertain economic condition that may trail any improvements in the United States.

We are subject to risks associated with the imposition of legislation and regulations relating to the import or export of high technology products, information and technology. We cannot predict whether quotas, duties, taxes or other charges or restrictions upon the importation or exportation of our products will be implemented by the United States or other countries. Because sales of our products have been denominated to date primarily in United States dollars, increases in the value of the United States dollar could increase the price of our products so that they become relatively more expensive to customers in the local currency of a particular country, leading to a reduction in sales and profitability in that country. Future international activity may result in increased foreign currency denominated sales. Gains and losses on the conversion to United States dollars of accounts payable and other monetary assets and liabilities arising from international operations may contribute to fluctuations in our results of operations.

Some of our customer purchase orders and agreements are governed by foreign laws, which may differ significantly from laws in the United States, or may require that dispute resolution occur in a foreign country. As a result, our ability to enforce our rights under such agreements may be limited compared with our ability to enforce our rights under agreements governed by laws in the United States and adjudicated in the United States.

50

*Our foreign operations may subject us to risks relating to the U.S. Foreign Corrupt Practices Act, anti-bribery statutes and similar foreign regulations that may have a material adverse impact on our business, financial condition or results of operations.

Our international operations are also subject to laws regarding the conduct of business overseas, such as the U.S. Foreign Corrupt Practices Act, or FCPA, and other anti-bribery regulations in foreign jurisdictions where we do business, such as China, India, Vietnam, and in Europe. The FCPA prohibits the provision of illegal or improper inducements to foreign government officials in connection with obtaining or retaining business overseas or to secure an improper commercial advantage. The FCPA also requires us to keep accurate books and records of business transactions and maintain an adequate system of internal accounting controls. Violations of the FCPA, anti-bribery statutes or other similar laws by us, any of our foreign subsidiaries, or any of our or their employees, executive officers, distributors or other agents or intermediaries could subject us and the individuals involved to significant criminal or civil liability. In recent years, the Department of Justice and SEC have significantly stepped up their investigation and prosecution of alleged FCPA violations. Any such allegations of non-compliance with the FCPA, anti-bribery statutes or other similar laws could harm our reputation, divert management attention and result in significant expenses, and could therefore materially harm our business, financial condition or results of operations.

*Our portfolio of short-term investments is exposed to certain market risks.

We maintain an investment portfolio of various holdings, types of instruments and maturities. These securities are recorded on our consolidated balance sheets at fair value with unrealized gains or losses reported as a separate component of accumulated other comprehensive (loss) income, net of tax. Our investment portfolio is exposed to market risks related to changes in interest rates and credit ratings of the issuers, as well as to the risks of default by the issuers and lack of overall market liquidity. Substantially all of these securities are subject to interest rate and credit rating risk and will decline in value if interest rates increase or one of the issuers’ credit ratings is reduced. Increases in interest rates or decreases in the credit worthiness of one or more of the issuers in our investment portfolio could have a material adverse impact on our financial condition or results of operations. During the fiscal year ended March, 31 2010, we recorded $4.1 million in write-downs in the carrying value of certain securities as we determined the decline in the fair value of these securities to be other-than-temporary. If there is a further deterioration in market conditions or there are additional losses incurred, we may be required to record a further decline in the carrying value of these securities resulting in further charges. At December 31, 2012, the unrealized losses on these securities that were not written down as an other-than-temporary impairment charge were approximately $1.2 million, of which substantially the entire amount has been at an unrealized loss for greater than 12 months. If the fair value of any of these securities does not recover to at least the amortized cost of such security or we are unable to hold these securities until they recover, we may be required to record a decline in the carrying value of these securities.

Our markets are subject to rapid technological change, so our success depends heavily on our ability to develop and introduce new products.

The markets for our products are characterized by:

• rapidly changing technologies;

• evolving and competing industry standards;

• changing customer needs;

• frequent introductions of new products and enhancements;

• increased integration with other functions;

• long design and sales cycles;

• short product life cycles; and

• intense competition.

To develop new products for the communications or other technology markets, we must develop, gain access to and use leading technologies in a cost-effective and timely manner and continue to develop technical and design expertise. We must have our products designed into our customers’ future products and maintain close working relationships with key customers in order to develop new products that meet customers’ changing needs. We must respond to changing industry standards, trends towards increased integration and other technological changes on a timely and cost-effective basis. Our pursuit of technological advances may require substantial time and expense and may ultimately prove unsuccessful. If we are not successful in adopting such advances, we may be unable to timely bring to market new products and our revenues will suffer.

Many of our products are based on industry standards that are continually evolving. Our ability to compete in the future will depend on our ability to identify and ensure compliance with these evolving industry standards. The emergence of new industry standards could render our products incompatible with products developed by major systems manufacturers. As a result, we could be required to invest significant time and effort and to incur significant expense to redesign our products to ensure compliance with relevant standards. If our products are not in compliance with prevailing industry standards or

51

requirements, we could miss opportunities to achieve crucial design wins which in turn could have a material adverse effect on our business, operating results and financial condition.

*The markets in which we compete are highly competitive, and we expect competition to increase in these markets in the future.

The markets in which we compete are highly competitive, and we expect that domestic and international competition will increase in these markets, due in part to deregulation, rapid technological advances, price erosion, changing customer preferences and evolving industry standards. Increased competition could result in significant price competition, reduced revenues, lower profit margins or loss of market share. Our ability to compete successfully in our markets depends on a number of factors, including:

• our ability to partner with OEM and channel partners who are successful in the market;

• success in designing and subcontracting the manufacture of new products that implement new technologies;

• product quality, interoperability, reliability, performance and certification;

• our ability to attract and retain key engineering, operations, sales and marketing employees and management;

• customer support;

• time-to-market;

• price;

• production efficiency;

• design wins;

• expansion of production of our products for particular systems manufacturers;

• end-user acceptance of the systems manufacturers’ products;

• market acceptance of competitors’ products; and

• general economic conditions.

Our competitors may offer enhancements to existing products, or offer new products based on new technologies, industry standards or customer requirements that are available to customers on a more timely basis than comparable products from us or that have the potential to replace or provide lower cost alternatives to our products. The introduction of enhancements or new products by our competitors could render our existing and future products obsolete or unmarketable. We expect that certain of our competitors and other semiconductor companies may seek to develop and introduce products that integrate the functions performed by our IC products on a single chip, thus eliminating the need for our products. Each of these factors could have a material adverse effect on our business, financial condition and results of operations.

In the transport communications IC markets, we compete primarily against companies such as Broadcom, Cortina, PMC-Sierra and Vitesse. In the embedded processor communications IC market, we compete with technology companies such as Freescale Semiconductor, Cavium and Intel. Our X-Gene products are likely to face competition from other technology companies entering the ARM 64-bit processor markets, as well as from Intel. Most of these companies may have substantially greater financial, marketing and distribution resources than we have. Certain of our customers or potential customers have internal IC design or manufacturing capabilities with which we compete. We may also face competition from new entrants to our target markets, including larger technology companies that may develop or acquire differentiating technology and then apply their resources to our detriment. Any failure by us to compete successfully in these target markets would have a material adverse effect on our business, financial condition and results of operations.

Our operating results depend on manufacturing output and yields of our ICs and printed circuit board assemblies, which may not meet expectations.

The yields on wafers we have manufactured decline whenever a substantial percentage of wafers must be rejected or a significant number of die on each wafer are nonfunctional. Such declines can be caused by many factors, including minute levels of contaminants in the manufacturing environment, design issues, defects in masks used to print circuits on a wafer and difficulties in the fabrication process. Design iterations and process changes by our suppliers can cause a risk of defects. Many of these problems are difficult to diagnose, are time consuming and expensive to remedy and can result in shipment delays.

We estimate yields per wafer and final packaged parts in order to estimate the value of inventory. If yields are materially different than projected, work-in-process inventory may need to be re-valued. We may have to take inventory write-downs as a result of decreases in manufacturing yields. We may suffer periodic yield problems in connection with new or existing products or in connection with the commencement of production using a new design geometry or at a new manufacturing facility.

*We must develop or otherwise gain access to improved IC process technologies.

Our future success will depend upon our ability to access new IC process technologies at competitive pricing from our foundry partners. In the future, we will be required to transition one or more of our IC products to process technologies with

52

smaller geometries, other materials or higher speeds in order to reduce costs or improve product performance. We may not be able to gain access to new process technologies in a timely or affordable manner or products based on these new technologies may not achieve market acceptance.

The complexity of our products may lead to errors, defects and bugs, which could negatively impact our reputation with customers and result in liability.

Products as complex as ours may contain errors, defects and bugs when first introduced or as new versions are released. Our products have in the past experienced such errors, defects and bugs. Delivery of products with production defects or reliability, quality or compatibility problems could significantly delay or hinder market acceptance of the products or result in a costly recall and could damage our reputation and adversely affect our ability to retain existing customers and attract new customers. Errors, defects or bugs could cause problems with device functionality, resulting in interruptions, delays or cessation of sales to our customers.

We may also be required to make significant expenditures of capital and resources to resolve such problems. We cannot assure you that problems will not be found in new products after commencement of commercial production, despite testing by us, our suppliers or our customers. Any such problems could result in:

• additional development costs;

• loss of, or delays in, market acceptance;

• diversion of technical and other resources from our other development efforts;

• claims by our customers or others against us; and

• loss of credibility with our current and prospective customers.

Any such event could have a material adverse effect on our business, financial condition and results of operations.

Regulatory authorities in jurisdictions into which we ship out products could levy fines or restrict our ability to export products.

A significant majority of our sales are made outside of the U.S. through the exporting and re-exporting of products. In addition to local jurisdictions’ export regulations, our U.S.-manufactured products and products based on U.S. technology are subject to U.S. laws and regulations governing international trade and exports. These laws and regulations include, but not limited to, the Foreign Corrupt Practices Act, the Export Administration Regulations (“EAR”), and trade sanctions against embargoed countries and destinations administered by the U.S. Department of the Treasury, Office of Foreign Assets Control (“OFAC”). Licenses or proper license exceptions are required for the shipment of our products to certain countries as well as for the transfer of certain information and technology to certain foreign countries, foreign nationals or other prohibited persons within the United States or abroad. A determination by the U.S. or local government that we have failed to comply with these or other export or anti-bribery regulations can result in penalties which may include denial of export privileges, fines, civil and criminal penalties and seizure of products. Such penalties could have a material adverse effect on our business, including our ability to meet our sales and earnings forecasts. Further, a change in these laws and regulations could restrict our ability to export to previously permitted countries, customers, distributors or other third parties. Any one or more of these sanctions or a change in laws or regulations could have a material adverse effect on our business, financial condition and results of operations.

*Potential U.S. tax legislation regarding our foreign earnings could materially and adversely impact our business and financial results.

Currently, a majority of our revenue is generated from customers located outside the U.S. and a substantial portion of our employees are located outside the U.S. Present U.S. income taxes and foreign withholding taxes have not been provided on undistributed earnings for our non–U.S. subsidiaries, because such earning are intended to be indefinitely reinvested in the operations of those subsidiaries. Our provision for income taxes could be adversely affected by tax costs related to intercompany realignments; by changes in accounting principles; or by changes in tax laws and regulations, including possible U.S. changes to the taxation of earnings of our foreign subsidiaries, the deductibility of expenses attributable to foreign income, or the foreign tax credit rules.

If our internal control over financial reporting is not considered effective, our business and stock price could be adversely affected.

Section 404 of the Sarbanes-Oxley Act of 2002 requires us to evaluate the effectiveness of our internal control over financial reporting as of the end of each fiscal year, and to include a management report assessing the effectiveness of our internal control over financial reporting in our annual report on Form 10-K for that fiscal year. Section 404 also requires our independent registered public accounting firm to attest to and report on the effectiveness of our internal control over financial reporting.

53

Our management, including our chief executive officer and chief financial officer, does not expect that our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of control must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of internal control can provide absolute assurance that all control issues and instances of fraud involving a company have been, or will be, detected. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and we cannot assure you that any design will succeed in achieving its stated goals under all potential future conditions. Over time, our internal control over financial reporting may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Our management has concluded, and our independent registered public accounting firm has attested, that our internal control over financial reporting was effective as of March 31, 2012. We cannot assure you that we or our independent registered public accounting firm will not identify a material weakness in our internal control over financial reporting in the future. A material weakness in our internal control over financial reporting would require management and our independent registered public accounting firm to report our internal control over financial reporting as ineffective. If our internal control over financial reporting is not considered effective, we may experience a restatement like we have in the past of our financial statements and/or a loss of public confidence, either of which could have an adverse effect on our business and on the market price of our common stock.

*Our future success depends in part on the continued service of our key senior management, design engineering, sales, marketing, and manufacturing personnel, our ability to identify, hire and retain additional, qualified personnel and successful succession planning.

Our future success depends to a significant extent upon the continued service of our senior management and engineering personnel and successful succession planning. The loss of key senior executives or engineers could have a material adverse effect on our business. There is intense competition for qualified personnel in the semiconductor industry, in particular design, product and test engineers. We may not be able to continue to attract and retain engineers or other qualified personnel necessary for the development of our business, or to replace engineers or other qualified personnel who may leave our employment in the future.

We also face the risks associated with our former employees assisting their new employers to recruit our key talent, in violation of their contractual non-solicitation and confidentiality covenants to us. For example, in December 2010, we commenced a lawsuit in the California Superior Court in Santa Clara County against two former AppliedMicro employees — one of whom was a former Company officer — and their new employer for causes of action including, among other things, breach of the employees’ contractual employee non-solicitation covenants to us in connection with their efforts to recruit key AppliedMicro engineers to leave AppliedMicro and to join their new company. In August 2011, following the results of our discovery in that action, we amended our complaint to add the CEO of the new employer as an additional defendant and additional causes of action, including breach of fiduciary duty and new breach of contract and contract interference claims. In September 2012, we further amended the complaint to add the acquiror of the employer as a defendant and additional causes of action. We are seeking to recover damages, including exemplary and punitive damages, in such action. In addition, while we encourage our employees to abide by all contractual and legal obligations owed to their former employers, there can be no assurance that we will not be the target of allegations made by other companies that we have, directly or indirectly, unlawfully solicited their employees to join us. There are significant costs associated with recruiting, hiring and retaining personnel, as well as significant actual and potential losses to our business arising from the delays in or cancellation of technology development, product completion and roll-out, customer design wins and product orders, and sales revenues caused by the departure of key engineering resources.

To manage our operations effectively, we will be required to continue to improve our operational, financial and management systems and to successfully hire, train, motivate, and manage our employees. Also, the integration of future business acquisitions would require significant additional management, technical and administrative resources. We cannot guarantee that we would be able to manage our expanded operations effectively.

Periods of contraction in our business may also inhibit our ability to attract and retain our personnel. As we respond to declining revenues and/or implement additional cost improvement measures such as reductions in force, our remaining key employees may lose confidence in the future performance of the Company and decide to leave. Loss of the services of, or failure to recruit, key design engineers or other technical and management personnel could be significantly detrimental to our product development or other aspects of our business.

54

Our ability to supply a sufficient number of products to meet demand could be severely hampered by a shortage of water, electricity or other supplies or by natural disasters or other catastrophes or by the effects of war, acts of terrorism or global threats.

The manufacture of our products requires significant amounts of water. Previous droughts have resulted in restrictions being placed on water use by manufacturers. In the event of a future drought, reductions in water use may be mandated generally and our external foundries’ ability to manufacture our products could be impaired.

Several of our facilities, including our principal executive offices, are located in California. California has experienced prolonged energy alerts and blackouts caused by disruption in energy supplies. As a consequence, businesses and other energy consumers in California continue to experience substantially increased costs of electricity and natural gas. We are unsure whether energy alerts and blackouts will reoccur or how severe they may become in the future. Many of our customers and suppliers are also headquartered or have substantial operations in California. If we or any of our major customers or suppliers located in California experience a sustained disruption in energy supplies, our results of operations could be materially and adversely affected.

A significant portion of our manufacturing operations are located in Asia. These areas are subject to natural disasters such as earthquakes or floods, like Japan and Thailand. We do not have earthquake insurance for these facilities, because adequate coverage is not offered at economically justifiable rates. A significant natural disaster or other catastrophic event could have a material adverse impact on our business, financial condition and operating results.

The effects of war, acts of terrorism or global threats, including, but not limited to, the outbreak of epidemic disease, could have a material adverse effect on our business, operating results and financial condition. The continued threat of terrorism and heightened security and military action in response to this threat, or any future acts of terrorism, may cause further disruptions to local and global economies and create further uncertainties. To the extent that such disruptions or uncertainties result in delays or cancellations of customer orders, or the manufacture or shipment of our products, our business, operating results and financial condition could be materially and adversely affected.

*We could incur substantial fines or litigation costs associated with our storage, use and disposal of hazardous materials.

We are subject to a variety of federal, state and local governmental regulations related to the use, storage, discharge and disposal of toxic, volatile or otherwise hazardous chemicals used in our manufacturing process. Any failure to comply with present or future regulations could result in the imposition of fines, the suspension of production or a cessation of operations. These regulations could require us to acquire costly equipment or incur other significant expenses to comply with environmental regulations or clean up prior discharges.

Since 1993, we have been named as a potentially responsible party (“PRP”) along with more than 100 other companies that used Omega Chemical Corporation waste treatment facility in Whittier, California (the “Omega Site”). The U.S. Environmental Protection Agency (“EPA”) has alleged that the Omega Site failed to properly treat and dispose of certain hazardous waste material. We are a member of a large group of PRPs that has agreed to fund certain on-going remediation efforts at the Omega Site and with respect to the regional groundwater allegedly contaminated thereby.

In 2007, the PRPs were sued by a chemical company located downstream from the Omega Site, seeking a judicial determination that the Omega PRPs are responsible for some or all of the plaintiff’s potential liability to clean up groundwater contamination beneath Plaintiff’s site; that action has been stayed since March 2008 to allow for further delineation of the regional groundwater. In September 2011, EPA issued an interim remedial action proposal, designed to arrest the further spread of groundwater contamination; in the next few months EPA is expected to notify the PRPs with requests to implement the interim remedial action. In 2010, a toxic tort litigation was commenced against Omega and the PRP group by individuals alleging injuries caused by the Omega Site; that litigation was settled and dismissed with prejudice in September 2012.

Based on currently available information, we have a loss accrual for the Omega site that is not material and we believe that the actual amount of costs and liabilities will not be materially different from the amount accrued. However, proceedings are ongoing and the eventual outcome of the clean-up efforts and the pending litigation matter is uncertain at this time. Based on currently available information, we do not believe that any eventual outcome will have a material adverse effect on our operations but we cannot guarantee this result. In 2009, the U.S. Supreme Court decided U.S. v. Burlington Northern & Santa Fe Railway Co., 129 S.Ct. 1870, which determined that hazardous substance cleanup liability need not be joint and several in all cases. As a result of this decision, the liability is potentially divisible among the PRPs at an earlier stage in superfund cases such as Omega. At this time we do not know and cannot predict the full impact of this decision on our liability.

In November 2011, a significant member of the PRP group withdrew from the group. In January 2012, as a result of the PRP group’s modification of its allocation formulae and group member withdrawal, our proportional allocation of

55

responsibility among the PRPs for the current remediation space increased. Any future increases to our proportional allocation of responsibility among the PRPs or the future reduction of parties participating in the PRP group due to additional member withdrawals could materially increase our potential liability relating to the Omega Site. Although we believe that we have been and currently are in material compliance with applicable environmental laws and regulations, we cannot guarantee that we are or will be in material compliance with these laws or regulations or that our future obligations to fund any remediation efforts, including those at the Omega Site, or expenses and potential liabilities relating to the pending litigation matter, will not have a material adverse effect on our business and financial condition.

*Customer demands and new regulations related to conflict-free minerals may force us to incur additional expenses.

In August 2012, under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the SEC adopted new requirements for companies that use certain minerals and derivative metals (referred to as “conflict minerals,” regardless of their actual country of origin) in their products. These new requirements will require companies to investigate, disclose and report whether or not such metals originated from the Democratic Republic of Congo or adjoining countries. In October 2012, the National Association of Manufacturers and the U.S. Chamber of commerce filed a petition for review in the U.S. Court of Appeals for the District of Columbia in response to a piece of Dodd-Frank regulation that requires public companies to disclose whether their products have been manufactured with these conflict minerals in countries where the sale of these minerals fuel humanitarian violence. The outcome of this suit is uncertain and may impact the adoption of these new requirements.

In the semiconductor industry, these minerals are most commonly found in metals. As there may be only a limited number of suppliers offering “conflict free” metals, we cannot be sure that we will be able to obtain necessary metals in sufficient quantities or at competitive prices. Also, since our supply chain is complex and some suppliers will not share their confidential supplier information, we may face challenges with our customers and suppliers if we are unable to sufficiently verify that the metals used in our products are “conflict free.” Some customers may choose to disqualify us as a supplier and we may have to write off inventory in the event that it becomes unsalable as a result of these regulations.

Environmental laws and regulations could cause a disruption in our business and operations.

We are subject to various state, federal and international laws and regulations governing the environment, including those restricting the presence of certain substances in electronic products and making manufacturers of those products financially responsible for the collection, treatment, recycling and disposal of certain products. Such laws and regulations have been passed in several jurisdictions in which we operate, including various European Union (“EU”) member countries. For example, the EU has enacted the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (“RoHS”) and the Waste Electrical and Electronic Equipment (“WEEE”) directives. RoHS prohibits the use of lead and other substances in semiconductors and other products put on the market after July 1, 2006. The WEEE directive obligates parties that place electrical and electronic equipment on the market in the EU to put a clearly identifiable mark on the equipment, register with and report to EU member countries regarding distribution of the equipment, and provide a mechanism to take back and properly dispose of the equipment. There can be no assurance that similar programs will not be implemented in other jurisdictions resulting in additional costs, possible delays in delivering products, and even the discontinuance of existing and planned future product replacements if the cost were to become prohibitive.

We may not be able to protect our intellectual property adequately.

We rely in part on patents to protect our IP. We cannot assure you that our pending patent applications or any future applications will be approved, or that any issued patents will adequately protect the IP in our products and processes, will provide us with competitive advantages or will not be challenged by third parties or that if challenged, any such patents will be found to be valid or enforceable. Others may independently develop similar products or processes, duplicate our products or processes or design around any patents we currently hold or that may be issued to us.

To protect our IP, we also rely on the combination of mask work protection under the Federal Semiconductor Chip Protection Act of 1984, trademarks, copyrights, trade secret laws, employee and third-party nondisclosure agreements, and licensing arrangements. Despite these efforts, we cannot assure you that others will not independently develop substantially equivalent IP or otherwise gain access to our trade secrets or IP, or disclose such IP or trade secrets, or that we can meaningfully protect our IP. A failure by us to meaningfully protect our IP could have a material adverse effect on our business, financial condition and operating results.

We generally enter into confidentiality agreements with our employees, consultants, suppliers, customers and strategic partners. We also try to control access to and distribution of our technologies, documentation and other proprietary information. Despite these efforts, parties may attempt to copy, disclose, obtain or use our products, services or technology without our authorization. Also, former employees may seek employment with our business partners, customers or competitors and we cannot assure you that the confidential nature of our proprietary information will be maintained in the course of such future

56

employment. Additionally, former employees or third parties could attempt to penetrate our network to misappropriate our proprietary information or interrupt our business. Because the techniques used by computer hackers to access or sabotage networks change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques. As a result, our technologies and processes may be misappropriated, particularly in foreign countries where laws may not protect our proprietary rights as fully as in the United States.

*We could be harmed by litigation involving patents, proprietary rights or other claims.

Litigation may be necessary to enforce our IP rights, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement or misappropriation. The semiconductor industry is characterized by substantial litigation regarding patent and other IP rights. Currently the Company is not a named defendant in any IP infringement lawsuits. Nevertheless, as our products and IP become instantiated in more and more customer products and applications, and as patent infringement litigation brought by our competitors, non-practicing entities (also known as “NPEs” or “patent trolls”) and patent-licensing companies is on the rise, we are at an increased risk of being named as a defendant in such litigation. Due in part to the factors described above, the Company has been or currently is subject to the following:

• having information about our products and technologies subpoenaed in patent litigation between other third parties;

• demands that we enter into expensive licenses of third party patent portfolios in order to avoid being named as a defendant in future IP infringement suits; and

• claims demanding that we indemnify or reimburse customers or end users of our products with respect to their potential liability, including without limitation defense costs, arising from third party IP infringement claims brought against them.

Such claims, demands and litigation could result in substantial costs and diversion of resources, including the attention of our management and technical personnel, and could have a material adverse effect on our business, financial condition and results of operations.

We may be accused of infringing on or misappropriating the IP rights of third parties. In addition, we have contractual indemnification obligations to some of our customers, and other customers or end users may assert we have duties to indemnify them, with respect to claims that our products infringe third-party IP rights. For example, in connection with the patent infringement lawsuit previously brought by Broadcom Corporation against Emulex Corporation in the United States District Court in the Central District of California, Emulex demanded that several of its components suppliers, including AppliedMicro, indemnify Emulex from and against certain legal expenses and other potential liabilities arising from the lawsuit. Although we are a supplier of components used by Emulex in certain products accused in the Broadcom litigation, we do not currently believe we have any obligations under the terms of our existing supply agreement with Emulex to indemnify it with respect to the Broadcom litigation. Notwithstanding the foregoing, there can be no assurance that IP infringement or misappropriation claims by third parties, or additional claims for indemnification by customers or end users resulting from infringement claims against them, will not be asserted in the future, or that any such existing or future assertions will not harm our business.

In addition, in the past we have sold to third parties, including NPEs, groups of patents previously issued to or acquired by us that we deemed to be no longer essential to our core product lines and technologies. Such NPEs have on at least three occasions brought legal action asserting infringement of the acquired patents against various defendants, including customers or potential customers of ours. Although we and all of our customers are licensed under such acquired patents with respect to all products sold by us, nevertheless certain customers, against whom the NPEs have asserted infringement of the acquired patents by products other than ours (e.g., products internally developed by the customer or purchased from third-party suppliers other than us), have reacted adversely to us based on our initial sale of the acquired patents to the NPEs. Such adverse reactions have included, among other things, demands that we reimburse the customer for expenses incurred in defending against or settling the legal action, as well as threats to reduce or discontinue the customer’s current or future business with us. There can be no assurance that any such expense reimbursement payments or other financial consideration extended to such affected customers or any actual reduction or discontinuance of product sales to such affected customers would not adversely affect our business, financial condition or operating results.

Any litigation relating to the IP rights of third parties would at a minimum be costly and could divert the efforts and attention of our management and technical personnel. In the event of any adverse ruling in any such litigation, we could be required to pay substantial damages, cease the manufacturing, use and sale of infringing products, discontinue the use of certain processes or obtain a license under the IP rights of the third party claiming infringement. A license might not be available on reasonable, economic and other terms or at all. From time to time, we may be involved in litigation relating to other claims arising out of our operations in the normal course of business. The ultimate outcome of any such litigation matters could have a material, adverse effect on our business, financial condition or operating results.

57

Our stock price is volatile.

The market price of our common stock has fluctuated significantly. In the future, the market price of our common stock could be subject to significant fluctuations due to general economic and market conditions and in response to quarter-to-quarter variations in:

• our anticipated or actual operating results;

• announcements or introductions of new products by us or our competitors;

• anticipated or actual operating results of our customers, peers or competitors;

• technological innovations or setbacks by us or our competitors;

• conditions in the semiconductor, communications or information technology markets;

• the commencement or outcome of litigation or governmental investigations;

• changes in ratings and estimates of our performance by securities analysts;

• announcements of merger or acquisition transactions;

• management changes;

• our inclusion in certain stock indices; and

• other events or factors.

The stock market in recent years has experienced extreme price and volume fluctuations that have affected the market prices of many high technology companies, particularly semiconductor companies. In some instances, these fluctuations appear to have been unrelated or disproportionate to the operating performance of the affected companies. Whether or not our stock is part of one or more Index funds could have a significant impact on our stock. We cannot assure you that our stock will be part of any Index fund. In addition, the current decline of the financial markets and related factors beyond our control, including the credit and mortgage crisis in both the U.S. and worldwide, may cause our stock price to decline rapidly and unexpectedly.

Delaware law and our corporate charter and bylaws contain anti-takeover provisions that could delay or discourage takeover attempts that stockholders may consider favorable.

Provisions in our certificate of incorporation, as amended, and our bylaws, as amended and restated, may have the effect of delaying or preventing a change of control or changes in our directors and management. These provisions include the following:

• the ability of the board of directors to issue up to 2.0 million shares of “blank check” preferred stock with terms designed to prevent or delay a takeover attempt, as described further below;

• the prohibition of cumulative voting in the election of directors, which would otherwise allow less than a majority of stockholders to elect director candidates;

• the requirement for advance notice for nominations of directors for election to the board or for proposing matters that can be acted upon at a stockholders’ meeting;

• the ability of the board of directors to alter our bylaws without obtaining stockholder approval;

• the requirement that any stockholder derivative actions and certain other intra-corporate disputes be litigated solely and exclusively in Delaware state court:

• the right of the board of directors to elect a director to fill a vacancy created by the expansion of the board of directors: and

• the prohibition of the right of stockholders to call a special meeting of stockholders.

Our board of directors has the authority to issue up to 2.0 million shares of preferred stock and to determine the price, rights, preferences and privileges and restrictions, including voting rights, of those shares without any further vote or action by our stockholders. The rights of the holders of common stock will be subject to, and may be harmed by, the rights of the holders of any shares of preferred stock that may be issued in the future. The issuance of preferred stock may delay, defer or prevent a change in control, as the terms of the preferred stock that might be issued could potentially prohibit our consummation of any merger, reorganization, sale of substantially all of our assets, liquidation or other extraordinary corporate transaction without the approval of the holders of the outstanding shares of preferred stock. The issuance of preferred stock could have a dilutive effect on our stockholders.

Because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law. These provisions may prohibit, restrict or significantly delay large stockholders, in particular those owning 15% or more of our outstanding voting stock, from merging or combining with us.

Although we believe these provisions in our charter and bylaws and under Delaware law collectively provide for an opportunity to receive higher bids by requiring potential acquirers to negotiate with our board of directors, they would apply even if the offer may be considered beneficial by some stockholders. In any event, these provisions may delay or prevent a third party from acquiring us. Any such delay or prevention could cause the market price of our common stock to decline.

58

If we issue additional shares of stock in the future, it may have a dilutive effect on our stockholders.

We have a significant number of authorized and unissued shares of our common stock available. These shares will provide us with the flexibility to issue our common stock for proper corporate purposes, which may include making acquisitions (including without limitation, our acquisition of Veloce) through the use of stock, adopting additional equity incentive plans and raising equity capital. Any issuance of our common stock may result in immediate dilution of our stockholders.

Restructuring and Related Activities [Abstract]

RESTRUCTURING CHARGES

RESTRUCTURING CHARGES

The Company recognizes restructuring costs related to asset impairment and exit or disposal activities. Cost relating to facilities closure, or lease commitments are recognized when the facility has been exited. Termination costs are recognized when the cost are deemed both probable and estimable.

December 2012 Restructuring Program

The Company implemented a restructuring program during the three months ended December 31, 2012to reorganize its' operations and reduce its workforce and related operating expenses. The plan includes eliminating job redundancies and reducing the Company's current workforce by approximately 70 employees. As a result, the Company recorded a charge of $1.5 million for employee severances and $4.7 million for an asset impairment. The asset impairment related to the impairment of the unamortized value of a software intellectual property license, which the Company no longer intends to use to develop new products. The Company expects the restructuring program to be completed by the end of its current fiscal year ended March 31, 2013.

The restructuring activity for the three months ended December 31, 2012 is described below.

	Workforce Reduction			Asset Impairment		Total
Restructuring charges	$	1,529		$	4,689	$	6,218
Cash payments	(97		)	—		(97		)
Liability	$	1,432		$	4,689	$	6,121

April 2011 Restructuring Program

The April 2011 restructuring program was implemented as part of the Company’s ongoing cost reduction efforts and to better align its global operations to achieve greater efficiencies. The Company moved more of its functions offshore, which would allow it to be closer and more connected to its customer’s third party subcontract manufacturers. The April 2011 restructuring plan included eliminating or relocating 25 positions. As a result of the April 2011 restructuring program, the Company recorded a charge of $0.9 million for employee severances for the three and nine months ended December 31, 2011.

Strategic Investments

The Company has entered into certain equity investments in privately held businesses to achieve certain strategic business objectives. The Company’s investments in equity securities of privately held businesses are accounted for under the cost method. Under the cost method, strategic investments in which the Company holds less than a 20% voting interest and on which the Company does not have the ability to exercise significant influence are carried at the lower of cost or cost reduced by other-than-temporary impairments, as appropriate. These investments are included in other assets on the Company’s condensed consolidated balance sheets. The Company periodically reviews these investments for other-than-temporary declines in fair value based on the specific identification method and writes down investments when an other-than-temporary decline has occurred. No other-than-temporary declines were recorded during the three and nine months ended December 31, 2012 and 2011. During the three and nine months ended December 31, 2012 and 2011, the Company invested zero and $0.5 million, and $2.25 million and $4.75 million, respectively, in non-marketable equity investments and these amounts were carried at cost.

The established guidelines for measuring fair value and expanded disclosures regarding fair value measurements are defined as a three-level valuation hierarchy for disclosure of fair value measurements as follows:

Level 1 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2 — Inputs (other than quoted market prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.

Level 3 — Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Valuation of instruments includes unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of assets or liabilities.

The following is a summary of cash, cash equivalents and available-for-sale investments by type of instruments measured at fair value on a recurring basis (in thousands):

Other-Than-Temporary Impairment

Based on an evaluation of securities that have been in a loss position, the Company did not recognize any other-than-temporary impairment charges, for the three and nine months ended December 31, 2012 and 2011. The Company considered various factors which included a credit and liquidity assessment of the underlying securities and the Company’s intent and ability to hold the underlying securities until its estimated recovery of amortized cost. As of December 31, 2012 and March 31, 2012, the Company also had $7.3 million and $7.5 million in gross unrealized gains, respectively. The basis for computing realized gains or losses is by specific identification.

Warranty reserves:

The Company’s products typically carry a one year warranty. The Company establishes reserves for estimated product warranty costs at the time revenue is recognized. Although the Company engages in extensive product quality programs and processes, its warranty obligation is affected by product failure rates, use of materials and service delivery costs incurred in correcting any product failure. Should actual product failure rates, use of materials or service delivery costs differ from the Company’s estimates, additional warranty reserves could be required, which could reduce its gross margin.

The following table summarizes warranty reserve activity (in thousands):

Net loss per share:

Shares used in basic net loss per share are computed using the weighted average number of common shares outstanding during each period. Shares used in diluted net loss per share include the dilutive effect of common shares potentially issuable upon the exercise of stock options, vesting of restricted stock units (“RSUs”) and outstanding warrants. However, potentially issuable common shares are not used in computing diluted net loss per share as their effect would be anti-dilutive due to the loss recorded during the periods presented. The reconciliation of shares used to calculate basic and diluted net loss per share consists of the following (in thousands, except per share data):

	Three Months Ended						Nine Months Ended
	December 31,						December 31,
	2012			2011			2012			2011
Net loss	$	(71,562	)	$	(7,077	)	$	(116,509	)	$	(15,106	)
Shares used in net loss per share computation:

Net effect of dilutive common share equivalents	—			—			—			—

Basic and diluted net loss per share	$	(1.08	)	$	(0.12	)	$	(1.81	)	$	(0.24	)

The effect of anti-dilutive securities (comprised of options and restricted stock units) totaling 5.4 million and 8.7 million equivalent shares for the three and nine months ended December 31, 2012, respectively, and 10.7 million and 8.8 million shares for the three and nine months ended December 31, 2011, respectively, have been excluded from the net loss per share computation, as their impact would be anti-dilutive because the Company has incurred losses in the periods presented.

The effect of dilutive securities (comprised of options and restricted stock units) totaling 1.4 million and 0.7 million equivalent shares for the three and nine months ended December 31, 2012, respectively, and 0.2 million and 0.5 million shares for the three and nine months ended December 31, 2011, respectively, have been excluded from the net loss per share computation, as their impact would be anti-dilutive because the Company has incurred losses in the periods presented.

Total equivalent shares excluded from the net loss per share computation are 6.8 million and 9.4 million for the three and nine months ended December 31, 2012, respectively, and 10.9 million and 9.3 million shares for three and nine months ended December 31, 2011, respectively.

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The condensed consolidated financial statements include all the accounts of Applied Micro Circuits Corporation (“AMCC”, “APM”, “AppliedMicro” or the “Company”), and its wholly-owned subsidiaries including Veloce Technologies Inc. (“Veloce”), which was consolidated in prior accounting periods as a variable interest entity (“VIE”) since the Company was determined to be its primary beneficiary. On June 20, 2012, the Company completed the acquisition of Veloce which became a wholly owned subsidiary of the Company as of this date. See note 4 of Notes to Condensed Consolidated Financial Statements. All significant intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management 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. The Company regularly evaluates estimates and assumptions related to its:

• capitalized mask sets including its useful lives, which affects cost of goods sold and property and equipment or R&D expenses, if not capitalized;

• inventory valuation, warranty liabilities, and revenue reserves, which affects cost of sales, gross margin, and revenues;

• allowance for doubtful accounts, which affects operating expenses;

• the unrealized losses or other-than-temporary impairments of short-term investments available for sale, which affects interest income (expense), net;

• the valuation of purchased intangibles and goodwill, which affects amortization and impairments of purchased intangibles and impairments of goodwill;

• Veloce accrued liability which considers: (i) estimating the total value of the expected Veloce consideration, (ii) determining the stage at which a milestone is deemed to be probable of attainment, (iii) the estimated progress towards achieving the milestone at the time such milestone was deemed probable of achievement, and (iv) estimating the approximate timing of the expected completion of the milestones and related payments;

• the potential costs of litigation, which affects operating expenses;

• the valuation of deferred income taxes, which affects income tax expense (benefit); and

• stock-based compensation, which affects gross margin and operating expenses.

The Company bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. The actual results experienced by the Company may differ materially and adversely from management’s estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected.

Stock-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

STOCK-BASED COMPENSATION

STOCK-BASED COMPENSATION

The Company accounts for stock based compensation activity using the modified prospective method. This method requires companies to estimate the fair value of stock-based compensation on the date of grant using an option-pricing model. The Company uses the Black-Scholes model to value stock-based compensation, excluding RSUs, which we use the fair market value of our common stock. The Black-Scholes model determines the fair value of share-based payment awards based on the stock price on the date of grant and is affected by assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, the Company’s stock price, volatility over the term of the awards and actual and projected employee stock option exercise behaviors. Option-pricing models were developed for use in estimating the value of traded options that have no vesting or hedging restrictions and are fully transferable. Although the fair value of stock options granted by the Company is estimated by the Black-Scholes model, the estimated fair value may not be indicative of the fair value observed in a willing buyer/willing seller market transaction.

The Company did not grant options during the three months ended December 31, 2012 and 2011. The fair value of the options granted during the nine months ended December 31, 2012 and 2011 is estimated as of the grant date using the Black-Scholes option-pricing model assuming the weighted-average assumptions listed in the following table:

	Nine Months Ended December 31,
	Employee Stock Options						Employee Stock Purchase Plans
	2012			2011			2012			2011
Expected life (years)	4.5			3.8			0.5			0.5
Risk-free interest rate	0.7		%	1.4		%	0.2		%	0.2		%
Volatility	54		%	48		%	50		%	55		%
Dividend yield	—			—			—			—
Weighted average fair value	$	2.47		$	3.83		$	1.50		$	1.92

The weighted average grant-date fair value per share of the restricted stock units awarded was $6.13 and $5.71 during the three and nine months ended December 31, 2012, respectively, compared to $8.02 and $9.21 during the three and nine months ended December 31, 2011, respectively. The weighted average fair value per share was calculated based on the fair market value of the Company’s common stock on the respective grant dates.

Effective April 1, 2012, the Company revised its estimated forfeiture rate used in determining the amount of stock-based compensation from 6.8% to 6.6% as a result of an decreasing rate of forfeitures in recent periods, which the Company believes is indicative of the rate it will experience during the remaining vesting period of currently outstanding unvested grants.

Total stock-based compensation expense	$	6,222	$	4,433		$	21,545	$	11,735

The amount of unearned stock-based compensation currently estimated to be expensed from now through fiscal 2016, including time and performance based awards that are expected to vest, at December 31, 2012 is $12.6 million. The weighted-average period over which the unearned stock-based compensation is expected to be recognized is approximately 1.4 years. If there are any modifications or cancellations of the underlying unvested securities, the Company may be required to accelerate, increase or cancel any remaining unearned stock-based compensation expense. Future stock-based compensation expense and unearned stock-based compensation will increase to the extent that the Company grants additional equity awards or assumes unvested equity awards in connection with acquisitions.

The above stock based compensation expense of approximately $21.5 million for the nine months ended December 31, 2012 does not include approximately $1.3 million of expense related to the acceleration of Veloce warrants. See note 5 of Notes to Condensed Consolidated Financial Statements for further details relating to the Veloce warrants.

Stockholders' Equity

9 Months Ended

Dec. 31, 2012

Stockholders' Equity Note [Abstract]

STOCKHOLDERS' EQUITY

STOCKHOLDERS’ EQUITY

Preferred Stock

The Certificate of Incorporation allows for the issuance of up to two million shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences, and the number of shares constituting any series of the designation of such series, without further vote or action by the stockholders.

Common Stock

At December 31, 2012, the Company had 375.0 million shares authorized for issuance and approximately 67.0 million shares issued and outstanding. At March 31, 2012, there were approximately 61.9 million shares issued and outstanding.

Employee Stock Purchase Plan

The Company had in effect the 1998 Employee Stock Purchase Plan (1998 Plan) under which 4.8 million shares of common stock was reserved for issuance. In August 2010, the Company’s stockholders approved the proposal to increase the number of shares reserved for issuance to 6.3 million shares. In August 2012, the Company’s stockholders approved the proposal to reserve an additional 1.8 million shares under the 2012 Employee Stock Purchase Plan (2012 Plan). Upon adoption of the 2012 Plan, the 1998 Plan was terminated. Under the terms of the 2012 Plan, purchases are made semiannually and the purchase price of the common stock is equal to 85% of the fair market value of the common stock on the first or last day of the offering period, whichever is lower. During the nine months ended December 31, 2012 and 2011, 0.4 million shares for each of these periods were issued under the 1998 Plan. At December 31, 2012, 6.6 million shares had been issued under all previous stock plans and none were available for future issuance, and 1.8 million shares were available for issuance under the 2012 Plan.

Stock Repurchase Program

In August 2004, the Board authorized a stock repurchase program for the repurchase of up to $200.0 million of the Company’s common stock. Under the program, the Company is authorized to make purchases in the open market or enter into structured stock repurchase agreements. In October 2008, the Board increased the stock repurchase program by $100.0 million. During the nine months ended December 31, 2012, approximately 0.1 million shares were repurchased on the open market at a weighted average price of $5.18 per share. During nine months ended December 31, 2011, approximately 3.5 million shares were repurchased on the open market at a weighted average price of $5.98 per share. From the time the program was first implemented in August 2004, the Company has repurchased on the open market a total of 17.3 million shares at a weighted average price of $10.04 per share. All repurchased shares were retired upon delivery to the Company.

The Company also utilizes structured stock repurchase agreements to buy back shares which are prepaid written put options on its common stock. The Company pays a fixed sum of cash upon execution of each agreement in exchange for the right to receive either a pre-determined amount of cash or stock depending on the closing market price of its common stock on the expiration date of the agreement. Upon expiration of each agreement, if the closing market price of its common stock is above the pre-determined price, the Company will have its cash investment returned with a premium. If the closing market price is at or below the pre-determined price, the Company will receive the number of shares specified at the agreement inception. The Company considered the guidance in ASC Topic 480-10, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity and ASC Topic 815-40, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock. Any cash received, including the premium, is treated as additional paid-in capital on the balance sheet.

During the nine months ended December 31, 2012, the Company did not enter into any structured stock repurchase agreements. During nine months ended December 31, 2011, the Company entered into structured stock repurchase agreements totaling $10.0 million for which it received 1.0 million in shares of its common stock at an effective purchase price of $9.74 per share from the settled structured stock repurchase agreements. At December 31, 2011, the Company had no outstanding structured stock repurchase agreements. From the inception of the Company’s most recent stock repurchase program in August 2004, it entered into structured stock repurchase agreements totaling $277.5 million. Upon settlement of these agreements, as of December 31, 2012, the Company received $179.8 million in cash and 10.0 million shares of its common stock at an effective purchase price of $9.78 per share.

The table below is a plan-to-date summary of the Company’s repurchase program activity as of December 31, 2012 (in thousands, except per share data):

	Aggregate Price		Repurchased Shares	Average Price Per Share
Stock repurchase program
Authorized amount	$	300,000	—	$	—
Open market repurchases	173,611		17,284	10.04
Structured stock repurchase agreements*	110,517		9,989	11.06
Total repurchases	$	284,128	27,273	$	10.42
Available for repurchase	$	15,872

* The amounts above do not include gains recorded to additional paid-in-capital of $12.8 million from structured stock repurchase agreements which settled in cash. The average price per share for structured stock repurchase agreements adjusted for gains from settlements in cash would have been $9.78 per share and for total repurchases would have been $9.97 per share.

Stock Options

The Company has granted stock options to employees and non-employee directors under several plans. These option plans include two stockholder-approved plans (the 1992 Stock Option Plan and 1997 Directors’ Stock Option Plan) and four plans not approved by stockholders (the 2000 Equity Incentive Plan, Cimaron Communications Corporation’s 1998 Stock Incentive Plan assumed in the fiscal 1999 merger, and JNI Corporation’s 1997 and 1999 Stock Option Plans assumed in the fiscal 2004 merger). Certain other outstanding options were assumed through the Company’s various acquisitions.

In April 2011, the Compensation Committee and the Board of Directors approved the Company’s 2011 Equity Incentive Plan (“2011 Plan”). The Company’s stockholders approved the 2011 Plan during its August 2011 annual meeting. The 2011 Plan serves as a successor to the 1992 Plan and no additional equity awards will be granted under the 1992 Plan. The total number of shares of common stock reserved for issuance under the 2011 Plan consists of 4.2 million shares plus up to 10.9 million shares subject to any stock awards under the 1992 Plan or the 2000 Plan that terminate or are forfeited or repurchased and would otherwise be returned to the share reserve under the 1992 Plan or the 2000 Plan, respectively.

The Board has delegated administration of the Company’s equity plans to the Compensation Committee, which generally determines eligibility, vesting schedules and other terms for awards granted under the plans. Options under the plans expire not more than ten years from the date of grant and are generally exercisable upon vesting. Vesting generally occurs over four years. New hire grants generally vest and become exercisable at the rate of 25% on the first anniversary of the date of grant and ratably on a monthly basis over a period of 36 months thereafter; subsequent option grants to existing employees generally vest and become exercisable ratably on a monthly basis over a period of 48 months measured from the date of grant.

In May 2009, Dr. Gopi, our CEO, was awarded 300,000 stock options for “Extraordinary Accomplishment.” The Black-Scholes value of these stock options is $1.1 million. These options will vest only if Company performance milestones are satisfied; otherwise they will expire unvested. The first milestone for 75,000 shares will vest only if we achieve an annual revenue target of $270 million or more for any fiscal year from fiscal 2010 through fiscal 2013. The next milestone for another 75,000 shares will vest only if we achieve an annual revenue target of $310 million or more for any fiscal year from fiscal 2010 through fiscal 2013 or an annual revenue target of $350 million or more for fiscal 2014. The last milestone for 150,000 shares will vest only if we achieve an annual operating margin of 13.5% of annual revenue or higher in fiscal 2013 or 15% or higher for any fiscal year from fiscal 2010 through fiscal 2012. The Company evaluates the probability of achieving the milestones and adjusts any stock option expense accordingly.

At December 31, 2012 and March 31, 2012, there were no shares of common stock subject to repurchase. Options are granted at prices at least equal to fair value of the Company’s common stock on the date of grant.

Option activity under the Company’s stock incentive plans during the nine months ended December 31, 2012 is set forth below (in thousands, except per share data):

	Number of Shares		Weighted Average Exercise Price Per Share
Outstanding at the beginning of the year	4,164		$	10.67
Granted	40		5.58
Exercised	(110	)	5.22
Forfeited	(406	)	15.56
Outstanding at the end of the period	3,688		$	10.24
Vested and expected to vest at the end of the period	3,675		$	10.25
Vested at the end of the period	3,105		$	10.50

At December 31, 2012, the weighted average remaining contractual term for options outstanding and vested is 3.3 years each.

The aggregate pretax intrinsic value of options exercised during the nine months ended December 31, 2012 was approximately $0.1 million. This intrinsic value represents the excess of the fair market value of the Company’s common stock on the date of exercise over the exercise price of such options.

The weighted average remaining contractual life and weighted average per share exercise price of options outstanding and of options exercisable as of December 31, 2012 were as follows (in thousands, except exercise prices and years):

	Options Outstanding				Options Exercisable
Range of Exercise Prices	Number of Shares	Weighted Average Remaining Contractual Life	Weighted Average Exercise Price		Number of Shares	Weighted Average Exercise Price
$  1.68 - $ 7.12	843	2.96	$	6.54	503	$	6.18
7.13 - 8.07	853	3.81	7.71		823	7.70
8.08 - 11.86	801	3.94	10.39		678	10.20
11.87 - 14.40	815	3.13	12.93		725	13.01
14.41 - 24.16	376	2.18	18.15		376	18.15
$  1.68 - $24.16	3,688	3.33	$	10.24	3,105	$	10.50

As of December 31, 2012, the aggregate pre-tax intrinsic value of options outstanding and exercisable was approximately $2.2 million and $1.8 million. The aggregate pre-tax intrinsic values were calculated based on the closing price of the Company’s common stock of $8.42 on December 31, 2012.

Restricted Stock Units

The Company has granted restricted stock units (“RSUs”) pursuant to its 1992 Plan, 2000 Equity Incentive Plan and 2011 Equity Incentive Plan as part of its regular annual employee equity compensation review program as well as to new hires. RSUs are share awards that, upon vesting, will deliver to the holder, shares of the Company’s common stock. Generally, RSUs vest ratably on a quarterly basis over four years from the date of grant. For employees hired after May 15, 2006, RSUs will vest on a quarterly basis over four years from the date of hire provided that no shares will vest during the first year of employment, at the end of which the shares that would have vested during that year will vest and the remaining shares will vest over the remaining 12 quarters.

In May 2009, the Company issued three years performance-based RSU grants, or “EBITDA” Grants which were completed in fiscal 2012 and no additional grants will be made under this grant.

In April 2011, the Committee authorized additional three years performance-based RSU grants, or “EBITDA2” Grants. EBITDA2 Grants are similar to the EBITDA Grant program introduced in 2009. The Company evaluates the probability of achieving the milestones and adjusts any RSU expense which is included in stock-based compensation expense. The Company believes that that it would be highly unlikely for any EBITDA2 shares to vest during the three-year life of the program. Fiscal 2012 was declared zero attainment and vesting target shares have rolled over to fiscal 2013. The Company expects that all shares issued under the EBITDA2 program will expire unvested when the program concludes in May 2014.

In November 2011 and February 2012, the Committee authorized additional 18 months performance-based RSU grants, or “Performance Retention Grants”, which are intended to incentivize superior performance and retain key employees. In May 2012, the Committee authorized 12 months Performance Retention Grants. Vesting for the Performance Retention Grants is subject to (i) the accomplishment of goals and objectives of the individual’s business unit and (ii) individual performance as measured by the accomplishment of individual goals and objectives. The 18-month RSU shares generally vest 2/3 after one year, with certain unearned amounts able to roll over to the subsequent vesting period, and 1/3 after 18 months. The 12-month RSU shares will have the opportunity to vest after 1 year. Unvested RSU shares remaining at the end of the program period will expire unvested. The Company evaluates the probability of achieving the goals and objectives and adjusts any RSU expense which is included in stock-based compensation expense.

In February 2012, Dr. Gopi was awarded 500,000 restricted stock units. The value of these restricted stock units is $3.7 million. These awards will vest only if the Company’s performance milestones relating to the Veloce merger are satisfied; otherwise they will expire unvested. The Company evaluates the probability of achieving the milestones and recognizes expense accordingly. During the three and nine months ended December 31, 2012, two of the performance milestones were assessed of being probable of completion and their associated expense has been recorded in the Company's financial statements during these periods.

Restricted stock unit activity during the nine months ended December 31, 2012 is set forth below (in thousands):

	Restricted Stock Units Outstanding Number of Shares
Outstanding at the beginning of the year	9,244
Awarded	894
Vested	(2,152	)
Cancelled	(1,322	)
Outstanding at the end of the period	6,664

The weighted average remaining contractual term for the restricted stock units outstanding as of December 31, 2012 was 1.4 years.

As of December 31, 2012, the aggregate pre-tax intrinsic value of restricted stock units outstanding was $56.1 million which includes performance based awards which are subject to milestone attainment. The aggregate pretax intrinsic values were calculated based on the closing price of the Company’s common stock of $8.42 on December 31, 2012.

The aggregate pretax intrinsic value of RSUs released during the nine months ended December 31, 2012 was $13.0 million. This intrinsic value represents the fair market value of the Company’s common stock on the date of release.

Warrants

On May 17, 2009, the Company entered into a development agreement with Veloce pursuant to which Veloce agreed, among other things, to perform development work for the Company on an exclusive basis for up to five years for cash and other consideration, including a warrant to purchase shares of the Company’s common stock (the “Warrant”). The Warrant vesting schedule was amended in conjunction with the amended development agreement on November 8, 2010. In connection with the Merger Agreement amendment entered into on April 5, 2012, the Company and Veloce further modified the Warrant by fully accelerating the vesting schedule resulting in the recognition of approximately $1.3 million of stock compensation expense during the quarter ended June 30, 2012. All vested shares were subsequently sold and the proceeds distributed, prior to the acquisition of Veloce by the Company on June 20, 2012.

Legal Proceedings

The Company is currently a party to various legal proceedings, including those noted in this section. While Management presently believes that the ultimate outcome of these proceedings, individually and in the aggregate, will not materially harm the Company's financial position, results of operations, cash flows, or overall trends, legal proceedings are subject to inherent uncertainties, unfavorable rulings or other events could occur. In addition, legal proceedings are expensive to prosecute and defend against and can divert Management attention and Company resources away from the Company's business objectives. Unfavorable resolutions could include monetary damages against the Company, or preclude the Company from recovering the damages it seeks in legal proceedings it has commenced. It is also possible that the Company could conclude it is in the best interests of its stockholders, employees, and customers to settle one or more such matters, and any such settlement could include substantial payments or the surrender of rights to collect substantial payments from third parties. However, The Company has not reached this conclusion with respect to any particular matter at this time.

In 1993, the Company was named as a Potentially Responsible Party (“PRP”) along with more than 100 other companies that used an Omega Chemical Corporation waste treatment facility in Whittier, California (the “Omega Site”). The U.S. Environmental Protection Agency (“EPA”) has alleged that Omega failed to properly treat and dispose of certain hazardous waste materials at the Omega Site. The Company is a member of a large group of PRPs, known as the Omega Chemical Site PRP Organized Group (“OPOG”) that has agreed to fund certain on-going remediation efforts at the Omega Site. In February 2001, the U.S. District Court for the Central District of California (the “Court”) approved a consent decree between EPA and OPOG to study contamination and evaluate cleanup options at the Omega Site (the Operable Unit 1 or “OU1”). In January 2009, the Court approved two amendments to the consent decree, the first expanding the scope of work to mitigate volatile organic compounds affecting indoor air quality near the Omega Site and the second adding settling parties to the consent decree. Removal of waste materials from the Omega Site has been completed. As part of OU1, efforts to remediate the soil and groundwater at the Omega Site, including without limitation the extraction of chemical vapors from the soil in and around the site, are underway and are expected to be ongoing for several years. In addition, OPOG and EPA are investigating a regional groundwater contamination plume allegedly originating at the Omega Site (the Operable Unit 2 or “OU2”). In September 2011, EPA issued an interim Record of Decision specifying the interim clean-up actions EPA has chosen for OU2, and in September 2012, it issued a special notice letter that triggered the commencement of good faith settlement negotiations with OPOG. It is anticipated that such settlement negotiations will result in EPA and OPOG entering into a remediation consent decree with the Court regarding OU2. In November 2007, Angeles Chemical Company, located downstream from the Omega Site, filed a lawsuit (the “Angeles Litigation”) in the Court against OPOG and the PRPs for cost recovery and indemnification for future response costs allegedly resulting from the regional groundwater contamination plume described above. In March 2008, the Court granted OPOG’s motion to stay the Angeles Litigation pending EPA’s determination of how to investigate and remediate the regional groundwater. In 2010, certain PRP’s challenged the criteria previously used to allocate liability among the PRP’s. In December 2011, an allocation committee established by OPOG to review those criteria recommended changes to the cost allocation structure that would, upon final approval, increase the Company’s overall share of liability within the PRP group. In addition, the recent departure of one or more PRPs from OPOG could have the effect of increasing the proportional liability of the remaining PRPs, including the Company. In January 2012, as a result of the allocation criteria modifications and PRP departure from OPOG described above, the Company’s proportional allocation of liability was increased. Although the Company considers a loss relating to the Omega Site probable, its share of any financial obligations for the remediation of the Omega Site, including taking into account the allocation increases described above, is not currently believed to be material to the Company’s financial statements, based on the Company’s approximately 0.5% contribution to the total waste tonnage sent to the site and current estimates of the potential remediation costs. Based on currently available information, the Company has a loss accrual that is not material and believes that the actual amount of its costs will not be materially different from the amount accrued. However, proceedings are ongoing and the eventual outcome of the clean-up efforts and the pending litigation matters is uncertain at this time. Based on currently available information, the Company does not believe that any eventual outcome will have a material adverse effect on its operations.

AppliedMicro TPack A/S, the Company’s wholly-owned subsidiary acquired in September 2010 (“TPack”), is involved in a contract dispute with Xtera Communications Inc. and its subsidiary Meriton Networks Canada Inc. (collectively, “Xtera”), regarding a software development and licensing agreement the parties entered into in September 2006. In August 2009, Xtera filed an action against TPack in the United States District Court for the Eastern Division of Texas, which was dismissed in October 2010 for lack of jurisdiction. In September 2009, TPack filed an action against Xtera in the Ontario Superior Court of Justice in Canada, which action was resumed in March 2011 following dismissal of the Texas action. In the Canadian action, TPack seeks contract damages from Xtera of approximately $1.0 million plus pre-judgment interest and expenses. In April 2011, Xtera filed a statement of defense and counter claim with the Ontario court, in which Xtera denies liability to TPack and seeks reimbursement of approximately $1.7 million in development fees and royalties previously paid to TPack, plus pre-judgment interest and expenses. Discovery in the legal proceedings is continuing. The Company does not currently anticipate that the TPack/Xtera legal proceedings will have a material adverse effect on the Company.

Accounting Policies [Abstract]

Basis of Presentation

The condensed consolidated financial statements include all the accounts of Applied Micro Circuits Corporation (“AMCC”, “APM”, “AppliedMicro” or the “Company”), and its wholly-owned subsidiaries including Veloce Technologies Inc. (“Veloce”), which was consolidated in prior accounting periods as a variable interest entity (“VIE”) since the Company was determined to be its primary beneficiary. On June 20, 2012, the Company completed the acquisition of Veloce which became a wholly owned subsidiary of the Company as of this date. See note 4 of Notes to Condensed Consolidated Financial Statements. All significant intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management 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. The Company regularly evaluates estimates and assumptions related to its:

• capitalized mask sets including its useful lives, which affects cost of goods sold and property and equipment or R&D expenses, if not capitalized;

• inventory valuation, warranty liabilities, and revenue reserves, which affects cost of sales, gross margin, and revenues;

• allowance for doubtful accounts, which affects operating expenses;

• the unrealized losses or other-than-temporary impairments of short-term investments available for sale, which affects interest income (expense), net;

• the valuation of purchased intangibles and goodwill, which affects amortization and impairments of purchased intangibles and impairments of goodwill;

• Veloce accrued liability which considers: (i) estimating the total value of the expected Veloce consideration, (ii) determining the stage at which a milestone is deemed to be probable of attainment, (iii) the estimated progress towards achieving the milestone at the time such milestone was deemed probable of achievement, and (iv) estimating the approximate timing of the expected completion of the milestones and related payments;

• the potential costs of litigation, which affects operating expenses;

• the valuation of deferred income taxes, which affects income tax expense (benefit); and

• stock-based compensation, which affects gross margin and operating expenses.

The Company bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. The actual results experienced by the Company may differ materially and adversely from management’s estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected.

Variable Interest Entity, Measure of Activity [Abstract]

VELOCE

VELOCE

On June 20, 2012 (the “Closing Date”), the Company completed its acquisition of Veloce pursuant to the terms of the Agreement and Plan of Merger, entered into as of May 17, 2009 (the “Initial Agreement”), as amended by Amendment No. 1 to Agreement and Plan of Merger, entered into as of November 8, 2010 (the “First Amendment”), and Amendment No. 2 to Agreement and Plan of Merger, entered into as of April 5, 2012 (the “Second Amendment” and, collectively with the Initial Agreement and the First Amendment, the “Merger Agreement”). The First Amendment was amended, restated and replaced in its entirety by the Second Amendment.

The terms of the Merger Agreement include the payment of initial consideration of up to $60.4 million, payable in shares of Company common stock and/or cash (at the Company's election) to holders of Veloce common stock, Veloce stock options that were vested on the Closing Date, and holders of Veloce stock equivalents (collectively, “Veloce Equity Holders”). During the three and nine months ended December 31, 2012, as part of the above arrangement, the Company issued 0.2 million shares valued at $1.1 million and 2.9 million shares valued at $16.0 million, respectively, and paid approximately $1.1 million and $15.9 million in cash, respectively. Of the $60.4 million that relates to the initial consideration, $31.9 million has been paid to date. To the extent payments of the $60.4 million are paid in the Company's common stock and relate to shares of Veloce stock that were outstanding at the date of the closing of the Merger, the value of the Company's common stock is fixed at $5.546 per share (“fixed shares”). The balance of the $60.4 million or approximately $28.5 million will be paid over multiple quarters and will include approximately 1.2 million fixed shares and at least $10.2 million in cash for a total value of $16.9 million.

The remaining $11.6 million of the $28.5 million will be paid in a combination of cash and shares of the Company's common stock valued at the then-current market price.

For accounting purposes, the consideration to be paid under the Merger Agreement is considered compensatory and is recognized as research and development expense when incurred. Recognition of these costs as expense will occur when the specific development and performance milestones become probable of achievement and the amount of expense will be based upon the estimated stage of product development to date. As of March 31, 2012, the first development and performance milestone set forth under the Merger Agreement was considered probable of achievement and the Company recognized $60.4 million of research and development expense.

The total estimated value to the Veloce Equity Holders is based on the Company achieving certain performance benchmarks defined under the Merger Agreement within a certain time period. The Company performed various simulations during the three months ended December 31, 2012. The results of the simulations exceeded expectations for certain of the benchmarks defined under the Merger Agreement, and as a result the estimated maximum value to the Veloce Equity Holders was increased from approximately $135 million to the contractual maximum of $178.5 million, based on the Company's current expectations regarding the achievement of such product development milestones. As such, the total expense that the company expects to recognize has been updated to be in the range of $117M (recognized through December 31, 2012) up to $178.5 million, depending upon the achievement of multiple product development cycles and technical performance results. The increase in the estimated value to the Veloce Equity Holders also resulted in an increase of the estimated value of the first performance milestone. Research and Development expense recognized during the three months ended December 31, 2012 relating to the first performance milestone was based upon the estimated stage of the development of the first milestone as of December 31, 2012 and the estimated value tied to the first performance milestone. The remaining costs associated with the first performance milestone, estimated value of the first milestone less expense recognized through December 31, 2012, will be recognized on a straight line basis, subject to adjustment for actual progress towards the milestones, over the remaining period of expected development which is currently estimated not to exceed the next three fiscal quarters.

Additionally, during the three months ended December 31, 2012, the second development and performance milestone set forth under the Merger Agreement was considered probable of achievement. The Company recognized research and development expenses that were based upon the estimated stage of development and estimated value tied to the second performance milestone. The remaining costs associated with the second performance milestone will be recognized on a straight line basis, subject to adjustment for actual progress towards the milestones, over the remaining period of expected development which is currently estimated not to exceed the next three fiscal quarters.

The third and last development and performance milestone set forth under the Merger Agreement was not yet considered probable of achievement as of December 31, 2012.

Total research and development expenses expected to be recognized upon completion of the first and second performance milestones is approximately $142.8 million (including the initial consideration of $60.4 million), of which approximately $117 million has been recognized through December 31, 2012. During the three and nine months ended December 31, 2012, expenses recognized in connection with first and second performance milestones were $51.9 million and $56.6 million, respectively. The amount and timing of expense recognition is determined based upon the probability of the respective performance milestone being achieved, the estimated progress of development, and estimated date of the milestone attainment. Timing of payments will be based upon actual attainment of the development and performance milestones, and upon vesting, if any, associated with outstanding Veloce' stock equivalents.
