NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.     DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Skyworks Solutions, Inc. together with its consolidated subsidiaries, (“Skyworks” or the “Company”) is an innovator of high reliability analog and mixed signal semiconductors. Leveraging core technologies, Skyworks offers diverse standard and custom linear products supporting automotive, broadband, cellular infrastructure, energy management, industrial, medical, military and cellular handset applications. The Company's portfolio includes amplifiers, attenuators, circulators, detectors, diodes, directional couplers, front-end modules, hybrids, infrastructure RF subsystems, isolators, mixers/demodulators, optocouplers, optoisolators, phase shifters, PLLs/synthesizers/VCOs, power dividers/combiners, receivers, switches and technical ceramics.

The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Certain information and footnote disclosures, normally included in annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), have been condensed or omitted pursuant to those rules and regulations. However, in management's opinion, the financial information reflects all adjustments, including those of a normal recurring nature necessary to present fairly the financial position, results of operations, and cash flows of the Company for the periods presented. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year. This information should be read in conjunction with the Company's financial statements and notes thereto contained in the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2011, filed with the SEC on November 28, 2010 (the "2011 10-K"), as amended by Amendment No. 1 to the 2011 10-K, filed with the SEC on January 30, 2012.

The Company evaluates its estimates on an ongoing basis using historical experience and other factors, including the current economic environment. Significant judgment is required in determining the reserves for and fair value of items such as inventory, income taxes, share-based compensation, loss contingencies, bad debts, contingent consideration associated with business combinations, and overall fair value assessments of assets and liabilities. In addition, significant judgment is required in determining whether a potential indicator of impairment of long-lived assets exists and in estimating future cash flows for any necessary impairment tests. Management's estimates could differ significantly from actual results.

The Company has evaluated subsequent events through the date of issuance of these unaudited consolidated financial statements.

The Company's fiscal year ends each year on the Friday closest to September 30. Fiscal 2012 consists of 52 weeks and ends on September 28, 2012. Fiscal 2011 consisted of 52 weeks and ended on September 30, 2011. The first quarters of fiscal 2012 and fiscal 2011 each consisted of 13 weeks and ended on December 30, 2011 and December 31, 2010, respectively.

2.     BUSINESS COMBINATIONS

On January 10, 2012, the Company acquired all of the outstanding shares of Advanced Analogic Technologies, Incorporated ("AATI") for a total purchase price of approximately $200.0 million in cash, net of cash acquired. AATI is an analog semiconductor company focused on enabling energy-efficient devices for consumer electronics, computing and communications markets. This acquisition expands Skyworks’ portfolio with highly complementary analog semiconductor products including battery chargers, DC/DC converters, voltage regulators and LED drivers. Due to the timing of the acquisition and its proximity to the filing date of this Quarterly Report on Form 10-Q, the Company has omitted the majority of the disclosures required under ASC 805 - Business Combinations ("ASC 805")as the initial accounting is incomplete.

3.     MARKETABLE SECURITIES

The Company accounts for its investment in marketable securities in accordance with ASC 320-Investments-Debt and Equity Securities ("ASC 320"), and classifies them as “available for sale.” At December 30, 2011, these securities included $3.2 million par value in auction rate securities ("ARS"), with a carrying value of $2.3 million. The difference between the par value and the carrying value is categorized as a temporary loss in other comprehensive income. The Company receives the scheduled interest payments in accordance with the terms of the ARS. The Company closely monitors and evaluates the appropriate accounting treatment in each reporting period for the ARS.

4.    FAIR VALUE

In accordance with ASC 820 - Fair Value Measurements and Disclosure (“ASC 820”), the Company groups its financial assets and liabilities measured at fair value on a recurring basis in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:

6

Level 1 - Valuation is based upon quoted market price for identical instruments traded in active markets.

Level 2 - Valuation is based upon quoted market prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3 - Valuation is generated from model-based techniques that use significant assumptions not observable in the market. Valuation techniques include use of discounted cash flow models and similar techniques.

The Company has cash equivalents classified as Level 1 and has no Level 2 securities. The Company's ARS, discussed in Note 3, Marketable Securities, are classified as Level 3 assets. There have been no transfers between Level 1, Level 2 or Level 3 assets or liabilities during the three months endedDecember 30, 2011. There have been no purchases, sales, issuances or settlements of the marketable securities classified as Level 3 assets during the three months endedDecember 30, 2011. The Company has classified its contingent consideration recorded for business combinations as a Level 3 liability. The Company reassessed the fair value of the contingent consideration and determined that there was no change during the three months endedDecember 30, 2011.

Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis

The Company measures certain financial assets and liabilities at fair value on a recurring basis such as our financial instruments, marketable securities and contingent consideration related to business combinations.

8.     BORROWING ARRANGEMENTS

LONG-TERM DEBT        

On March 2, 2007, the Company issued $200.0 million aggregate principal amount of convertible subordinated notes ("2007 Convertible Notes"). The offering contained two tranches. The first tranche consisted of $100.0 million of 1.25% convertible subordinated notes due March 2010 (the "1.25% Notes") which have been retired. The second tranche consisted of $100.0 million aggregate principal amount of 1.50% convertible subordinated notes due March 2012 (the "1.50% Notes"). During the three months endedDecember 30, 2011, the Company redeemed and retired $9.4 million of aggregate principal amount of the 1.50% Notes, paying a cash premium of $5.6 million which was accounted for as a reacquisition of equity instruments in accordance with ASC 470-20 - Debt, Debt with Conversions and Other Options ("ASC 470-20"). As of December 30, 2011, the remaining aggregate principal amount of the 1.50% Notes was $17.3 million, which the Company redeemed and retired subsequent to the Balance Sheet date for total cash paid of $32.8 million (including premium).

On October 3, 2009, the Company adopted ASC 470-20 which requires the issuer of convertible debt instruments with cash settlement features to separately account for the liability and equity components of the convertible debt instrument and requires retrospective application to all periods presented in the financial statements to which it is applicable. ASC 470-20 applies to the Company's 2007 Convertible Notes. Using a non-convertible borrowing rate of 6.86%, the Company estimated the fair value of the liability component of the $100.0 million aggregate principal amount of the 1.50% Notes to be $77.3 million as of October 3, 2009. As of the issuance date, the difference between the fair value of the liability component of the 1.50% Notes and the corresponding aggregate principal amount of such notes, which is equal to the fair value of the equity component of the 1.50% Notes, $22.7 million, was retrospectively recorded as a debt discount and as an increase to additional paid-in capital, net of tax. The remaining unamortized discount of the liability component of the 1.50% Notes was written off in January 2012 to correspond with the retirement of the remaining outstanding aggregate principal amount of the 1.50% Notes.

The following tables provide additional information about the Company's 2007 Convertible Notes (in thousands):

	As of
	December 30, 2011			September 30, 2011
Equity component of the convertible notes outstanding	$	3,926		$	6,061
Principal amount of the convertible notes	17,277			26,677
Unamortized discount of the liability component	154			588
Net carrying amount of the liability component	17,123			26,089
	Three-months Ended

Effective interest rate on the liability component	6.86		%	6.86		%
Cash interest expense recognized (contractual interest)	$	97		$	100
Effective interest expense recognized	$	351		$	328

The number of shares underlying the remaining 1.50% Notes was approximately 1.8 million at December 30, 2011.

9. INCOME TAXES

The Company recorded income tax provisions of $17.5 million and $15.9 million for the three months endedDecember 30, 2011 and December 31, 2010, respectively. The provision for income taxes for the three months endedDecember 30, 2011 consisted of $15.5 million and $2.0 million of United States and foreign income taxes, respectively, as compared to $15.2 million and $0.7 million for United States and foreign income taxes, respectively, for the three months endedDecember 31, 2010.

For the three months ended December 30, 2011 and December 31, 2010, the difference between the Company's effective tax rate and the 35% U.S. federal statutory rate resulted primarily from foreign earnings taxed at rates lower than the federal statutory rate, the recognition of research and development tax credits earned, and the domestic production activities deduction, partially offset by an increase in our tax expense related to a change in our reserve for uncertain tax positions. In December 2010, the United States Congress enacted legislation to retroactively extend the federal research and development tax credit. As a result, the Company

9

recognized $4.4 million of federal research and development tax credits in the three months endedDecember 31, 2010, which were earned in the fiscal year ended October 1, 2010.

On October 2, 2010, the Company expanded its presence in Asia by launching operations in Singapore. The Company operates under a tax holiday in Singapore, which is effective through September 30, 2020. The tax holiday is conditional upon the Company's compliance with meeting certain employment and investment thresholds in Singapore.

In accordance with GAAP, management has determined that it is more likely than not that a portion of the Company's historic and current year income tax benefits will not be realized. Accordingly, as of December 30, 2011, the Company has maintained a valuation allowance of $39.4 million. This valuation allowance is comprised of $26.1 million related to U.S. state tax credits and $13.3 million related to the Company's foreign deferred tax assets of which $11.6 million were acquired from SiGe in fiscal 2011.

Realization of benefits from the Company's deferred tax assets, net of valuation allowance, is dependent upon generating United States source taxable income in the future. The existing valuation allowance could be reversed in the future to the extent that the related deferred tax assets no longer require a valuation allowance under the provisions of ASC 740 - Income Taxes ("ASC 740").

The Company will continue to evaluate its valuation allowance in future periods and depending upon the outcome of that assessment, additional amounts could be reversed or recorded and recognized as an adjustment to income tax benefit or expense. Such adjustments could cause the Company's effective income tax rate to vary in future periods. The Company will need to generate $231.1 million of United States federal taxable income in future years to utilize all of the Company's net operating loss carryforwards, research and experimentation tax credit carryforwards, and deferred income tax temporary differences, net of valuation allowance, as of December 30, 2011.

During the three months ended December 30, 2011, the Company increased its gross unrecognized tax benefits by $3.9 million to $36.0 million. Of the total unrecognized tax benefits at December 30, 2011, $23.9 million would impact the effective tax rate, if recognized. The remaining unrecognized tax benefits would not impact the effective tax rate, if recognized, due to the Company's valuation allowance and certain positions which were required to be deferred. There are no positions that the Company anticipates could change within the next twelve months. The Company incurred $0.1 million of interest related to unrecognized tax benefits during the three months ended December 30, 2011. The Company's policy is to recognize accrued interest and penalties, if incurred, on any unrecognized tax benefits as a component of income tax expense.

10.    COMMITMENTS AND CONTINGENCIES

Legal Matters

From time to time, various lawsuits, claims and proceedings have been, and may in the future be, instituted or asserted against the Company, including those pertaining to patent infringement, intellectual property, environmental, product liability, safety and health, employment and contractual matters.

Additionally, the semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights. From time to time, third parties have asserted and may in the future assert patent, copyright, trademark and other intellectual property rights to technologies that are important to the Company's business and have demanded and may in the future demand that the Company license their technology. The outcome of any such litigation cannot be predicted with certainty and some such lawsuits, claims or proceedings may be disposed of unfavorably to the Company. Generally speaking, intellectual property disputes often have a risk of injunctive relief, which, if imposed against the Company, could materially and adversely affect the Company's financial condition, or results of operations. From time to time the Company may also be involved in legal proceedings in the ordinary course of business.

On June 6, 2011, a putative stockholder class action lawsuit was filed in California Superior Court in Santa Clara County (Case No. 111CV202403) (the “Bushansky action”) naming AATI, the members of AATI's board of directors, the Company and Merger Sub as defendants. The complaint alleges, among other things, (1) that the members of AATI's board of directors breached their fiduciary duties by (a) failing to take steps to maximize the value of the merger consideration to AATI's stockholders, (b) taking steps to avoid competitive bidding, and (c) failing to protect against conflicts of interest resulting from change-of-control and transaction-related benefits received by AATI directors in connection with the merger that are not available to all stockholders, and (2) that AATI, the members of AATI's board of directors, the Company and Merger Sub aided and abetted these purported breaches of fiduciary duties. The complaint seeks to enjoin consummation of the merger or, if the merger is completed, to recover damages caused by the alleged breaches of fiduciary duties. The complaint also seeks recovery of attorney's fees and costs of the lawsuit.

On June 7, 2011, a putative stockholder class action lawsuit was filed in California Superior Court in Santa Clara County (Case No. 111CV202501) (the “Venette action”) naming AATI, the members of AATI's board of directors, the Company and Merger Sub as defendants. Plaintiffs filed an amended complaint on July 14, 2011 (the “Amended Complaint”). The Amended Complaint alleges,

10

among other things, (1) that the members of AATI's board of directors breached their fiduciary duties by (a) agreeing to the merger for inadequate consideration on unfair terms, (b) failing to protect against conflicts of interest resulting from change-of-control and transaction-related benefits received by AATI directors in connection with the merger that are not available to all stockholders, (c) selling the company in response to alleged pressure from Dialectic Capital Partners, LP (“Dialectic”), (d) taking steps to avoid competitive bidding (including the entry by certain AATI officers and directors into agreements with the Company relating to voting commitments and inclusion in the merger agreement of non-solicitation provisions and a termination fee), and (e) by causing the issuance of a materially misleading Form S-4 Registration Statement which, inter alia, purportedly fails to disclose material facts surrounding (i) Dialectic's impact on the proposed merger process, (ii) the AATI board of directors' evaluation of the Company and its offer for AATI, and (iii) supporting figures and analysis regarding the fairness opinion that the AATI Board obtained from its financial advisor, Needham & Company, LLC, in connection with the transaction and (2) that AATI, the members of AATI's board of directors, the Company and Merger Sub aided and abetted these purported breaches of fiduciary duties. The Amended Complaint seeks to enjoin consummation of the merger, and to have the court direct the defendants to implement procedures and processes to maximize shareholder value. The Amended Complaint also seeks recovery of attorney's fees and costs of the lawsuit.

On July 26, 2011, the Court issued an order consolidating the Bushansky action and Venette action into a single, consolidated action captioned In re Advanced Analogic Technologies Inc. Shareholder Litigation, Lead Case No. 111CV202403, and designating the Amended Complaint as the operative complaint in the litigation. The Company believes that the claims in the consolidated action are without merit and intends to defend against such claims vigorously.

The Company believes that there is no other pending litigation involving the Company that will have, individually or in the aggregate, a material adverse effect on the business.

Guarantees and Indemnifications

The Company has made no contractual guarantees for the benefit of third parties. However, the Company generally indemnifies its customers from third-party intellectual property infringement litigation claims related to its products, and, on occasion, also provides other indemnities related to product sales. In connection with certain facility leases, the Company has indemnified its lessors for certain claims arising from the Company's activities at the facility or out of the lease.

The Company indemnifies its directors and officers to the maximum extent permitted under the laws of the state of Delaware. The duration of the indemnities varies, and in many cases is indefinite. The indemnities to customers in connection with product sales generally are subject to limits based upon the amount of the related product sales and in many cases are subject to geographic and other restrictions. In certain instances, the Company's indemnities do not provide for any limitation of the maximum potential future payments the Company could be obligated to make. The Company has not recorded any liability for these indemnities in the accompanying consolidated balance sheets and does not expect that such obligations will have a material adverse impact on its financial condition or results of operations.

11.     COMMON STOCK REPURCHASE

On August 3, 2010, the Board of Directors approved a stock repurchase program, pursuant to which the Company is authorized to repurchase up to $200.0 million of the Company's common stock from time to time on the open market or in privately negotiated transactions as permitted by securities laws and other legal requirements. During the three months endedDecember 30, 2011, the Company paid approximately $12.4 million (including commissions) in connection with the repurchase of 750,000 shares of its common stock (paying an average price of $16.54 per share). As of December 30, 2011, $117.6 million remained available under the existing share repurchase authorization.

Equity based awards exercisable for approximately 5.6 million shares and 1.7 million shares were outstanding but not included in the computation of earnings per share for the three months endedDecember 30, 2011 and December 31, 2010, respectively, as their effect would have been anti-dilutive.

13.     SEGMENT INFORMATION AND CONCENTRATIONS

In accordance with ASC 280-Segment Reporting ("ASC 280"), the Company has one reportable operating segment which designs, develops, manufactures and markets proprietary semiconductor products, including intellectual property. ASC 280 establishes standards for the way public business enterprises report information about operating segments in annual financial statements and in interim reports to shareholders. The method for determining what information to report is based on management's use of financial information for the purposes of assessing performance and making operating decisions. In evaluating financial performance and making operating decisions, management primarily uses consolidated net revenue, gross profit, operating profit and earnings per share. The Company's business units share similar economic characteristics, long term business models, research and development expenses and selling, general and administrative expenses. The Company continues to consider itself to have one reportable operating segment at December 30, 2011. The Company will re-assess its conclusions at least annually.

14.     RESTRUCTURING AND OTHER CHARGES

During the three months endedDecember 30, 2011, the Company recorded restructuring charges of$0.7 million associated with the acquisition and restructuring of SiGe. In addition, the Company made cash payments related to the restructuring plans of approximately $0.9 million during the three months endedDecember 30, 2011.

Activity and liability balances related to the Company's restructuring actions are as follows (in thousands):

	Facility Closings			License and Software Write-offs and Other			Workforce Reductions			Total
Restructuring balance, September 30, 2011	819			707			502			2,028

GENERAL

During the three months ended December 30, 2011, certain key factors contributed to our overall results of operations, financial position and cash flows. More specifically:

• Revenue increased by 17.5% to $393.7 million when compared to the corresponding period in the prior fiscal year. This increase in revenue is driven by our strategic diversification of products through key acquisitions made during fiscal 2011 in addition to growth in our core business.

• We generated $77.2 million in cash from operations during the fiscal quarter resulting in an ending cash, cash equivalents and restricted cash balance of $446.5 million at December 30, 2011.

• We redeemed and retired $9.4 million aggregate principal amount of our convertible debt during the three months endedDecember 30, 2011. Subsequent to quarter end, we retired the remaining outstanding balance of our convertible debt. In addition, we repurchased 750,000 shares of our common stock during the quarter for approximately $12.4 million.

In addition, in January 2012, we acquired Advanced Analog Technologies Incorporated ("AATI") for a total purchase price of approximately $200.0 million in cash, net of cash acquired. This Quarterly Report on Form 10-Q does not reflect the results of the acquisition of AATI.

NET REVENUE

	Three-months Ended
	December 30, 2011		Change		December 31, 2010
(dollars in thousands)
Net revenue	$	393,740	17.5	%	$	335,120

We market and sell our products directly to original equipment manufacturers of communication electronic products, third-party original design manufacturers, contract manufacturers, and indirectly through electronic components distributors. We periodically enter into revenue generating arrangements that leverage our broad intellectual property portfolio by licensing or selling our non-core patents or other intellectual property. We anticipate continuing this intellectual property strategy in future periods.

We generated net revenue of $393.7 million for the three months endedDecember 30, 2011, as compared to $335.1 million for the corresponding period in fiscal 2011, an increase of 17.5%. The increase in revenue was primarily driven by the contributions from the acquisitions made during the prior fiscal year and growth in our core business.

GROSS PROFIT

	Three-months Ended
	December 30, 2011			Change		December 31, 2010
(dollars in thousands)
Gross profit	$	171,850		15.7	%	$	148,538
% of net revenue	43.6		%			44.3		%

Gross profit represents net revenue less cost of goods sold. Cost of goods sold consists primarily of purchased materials, labor and overhead (including depreciation and share-based compensation expense) associated with product manufacturing.

Gross profit increased by $23.3 million for the three months endedDecember 30, 2011 as compared to the corresponding period in fiscal 2011. This increase was the result of the aforementioned increase in net revenue as quarter over quarter margin decreased slightly. Gross profit margin decreased to 43.6% for the three months endedDecember 30, 2011. The slight decrease in gross profit margin was due to increased share-based compensation and a shift in product mix offset by higher factory utilization. During the first quarter of fiscal 2012, we continued to benefit from higher contribution margins associated with the licensing and/ or sale of intellectual property.

14

RESEARCH AND DEVELOPMENT

	Three-months Ended
	December 30, 2011			Change		December 31, 2010
(dollars in thousands)
Research and development	$	46,941		21.8	%	$	38,543
% of net revenue	11.9		%			11.5		%

Research and development expenses consist primarily of direct personnel costs including share-based compensation expense, costs for pre-production evaluation and testing of new devices, masks and engineering prototypes and design and test tool costs.

The 21.8%increase in research and development expenses for the three months endedDecember 30, 2011 when compared to the corresponding period in fiscal year 2011 is principally attributable to higher head count and related compensation expense associated with prior year acquisitions and increased internal design activity in support of product development for our target markets.

SELLING, GENERAL AND ADMINISTRATIVE    

	Three-months Ended
	December 30, 2011			Change		December 31, 2010
(dollars in thousands)
Selling, general and administrative	$	35,702		16.7	%	$	30,606
% of net revenue	9.1		%			9.1		%

Selling, general and administrative expenses include legal, accounting, treasury, human resources, information systems, customer service, bad debt expense, sales commissions, share-based compensation expense, advertising, marketing and other costs.

The increase in selling, general and administrative expenses for the three months endedDecember 30, 2011 as compared to corresponding period in fiscal 2011 is principally due to an increase in head count and related compensation expense.

ACQUISITION RELATED EXPENSE

	Three-months Ended
	December 30, 2011			Change		December 31, 2010
(dollars in thousands)
Acquisition related expense	$	7,207		1,519.6	%	$	445
% of net revenue	1.8		%			0.1		%

Acquisition related expenses include costs associated with business combinations and include third party services related to legal, tax and accounting procured in connection to acquisitions completed or contemplated during the period.

The increase in acquisition related expenses for the three months ended December 30, 2011 as compared to the corresponding period in fiscal 2011 is principally related to the acquisition and arbitration expenses associated with acquiring AATI.

AMORTIZATION OF INTANGIBLES

	Three-months Ended
	December 30, 2011			Change		December 31, 2010
(dollars in thousands)
Amortization of intangibles	$	6,312		294.0	%	$	1,602
% of net revenue	1.6		%			0.4		%

The increase in amortization expense for the three months endedDecember 30, 2011 is related to the intangible assets recognized during the prior fiscal year.

15

PROVISION FOR INCOME TAXES    

	Three-months Ended
	December 30, 2011			Change		December 31, 2010
(dollars in thousands)
Provision for income taxes	$	17,536		10.5	%	$	15,868
% of net revenue	4.5		%			4.7		%

The provision for income taxes was $17.5 million ($15.5 million and $2.0 million for United States and foreign income taxes, respectively) and $15.9 million ($15.2 million and $0.7 million for United States and foreign income taxes, respectively) for the three months endedDecember 30, 2011 and December 31, 2010, respectively. The effective tax rate for the three months endedDecember 30, 2011 was 23.5% as compared to 20.7% for the corresponding period in fiscal 2011. As a result of the enactment of the Tax Relief Act of 2010, the tax rate of 20.7% for the three months ended December 31, 2010 included $4.4 million of federal research and development tax credits earned in fiscal 2010. Without the retroactive reinstatement of this tax credit, our effective tax rate would have been 26.5%.

The difference between our year to date effective tax rate of 23.5% and the federal statutory rate of 35% is principally due to the recognition of foreign earnings in lower tax jurisdictions, the recognition of research and development tax credits earned, and the domestic production activities deduction, partially offset by an increase in our tax expense related to a change in our reserve for uncertain tax positions.

LIQUIDITY AND CAPITAL RESOURCES

	Three-months Ended
(dollars in thousands)	December 30, 2011				December 31, 2010
Cash and cash equivalents at beginning of period (1)	$	410,087			$	453,257
Net cash provided by operating activities	77,232				64,822
Net cash used in investing activities	(6,424		)		(36,970		)
Net cash used in financing activities	(35,259		)		(31,055		)
Cash and cash equivalents at end of period (1)	$	445,636		(2)	$	450,054

_________________________

(1) Excludes restricted cash balances

(2) Does not reflect the acquisition of AATI in January 2012.

Cash Flow from Operating Activities:

Cash provided from operating activities is net income adjusted for certain non-cash items and changes in certain operating assets and liabilities. During the three months endedDecember 30, 2011, we generated $77.2 million in cash flow from operations, an increase of $12.4 million when compared to $64.8 million generated during the three months endedDecember 31, 2010. The increased cash from operations was primarily due to an increase in non-cash expenses such as amortization of intangibles and depreciation offset by the decrease in deferred taxes and the change in net working capital.

Cash Flow from Investing Activities:

Cash used in investing activities consists of cash paid for acquisitions, net of cash acquired, and capital expenditures. We had net cash outflows of $6.4 million during the three months endedDecember 30, 2011, compared to $37.0 million during the three months endedDecember 31, 2010. This decrease is primarily due to lower capital expenditure activity during the three months ended December 30, 2011.

Cash Flow from Financing Activities:

Cash flows from financing activities consist primarily of cash transactions related to debt and equity. During the three months endedDecember 30, 2011, we had net cash outflows of $35.3 million, compared to $31.1 million during the prior fiscal period. During the three months endedDecember 30, 2011, we had the following significant uses of cash:

• $15.4 million related to payroll tax withholdings on the vesting of employee performance and restricted stock awards;

• $12.4 million related to our repurchase of approximately 750,000 shares of our common stock pursuant to the share

16

repurchase program approved by our Board of Directors on August 3, 2010;

• $14.9 million for the redemption and retirement of $9.4 million aggregate principal amount of our convertible notes.

These uses of cash were partially offset by the net proceeds from employee stock option exercises of $2.3 million and a tax benefit from stock option exercises of $5.3 million during the three months endedDecember 30, 2011.

Liquidity:

Cash and cash equivalent balances (excluding restricted cash) increased$35.5 million to $445.6 million at December 30, 2011 from $410.1 million at September 30, 2011. Our net cash position, including our debt, increased by $44.5 million to $428.5 million at December 30, 2011 from $384.0 million at September 30, 2011. Subsequent to December 30, 2011, we retired the remaining aggregate principal amount of our convertible debt. In January 2012 we acquired 100% of AATI for approximately $200.0 million in cash, net of cash received. Based on our historical results of operations, we expect our existing sources of liquidity, together with cash expected to be generated from operations, will be sufficient to fund our research and development, capital expenditures, debt obligations including the cash premium, contingent consideration for our completed acquisitions, future acquisitions, working capital and other cash requirements for at least the next 12 months. However, we cannot be certain that the capital required to fund these expenses will be available in the future. In addition, any strategic investments and acquisitions that we may make may require additional capital resources. If we are unable to obtain sufficient capital to meet our capital needs on a timely basis and on favorable terms, our business and operations could be materially and adversely affected.

Our invested cash balances primarily consist of money market funds where the underlying securities primarily consist of United States treasury obligations, United States agency obligations and repurchase agreements collateralized by United States Government and agency obligations. Our invested cash balances also include time deposits and certificates of deposit.

CONTRACTUAL OBLIGATIONS

Our contractual obligations disclosure in our Annual Report on Form 10-K for the fiscal year ended September 30, 2011, filed with the SEC on November 28, 2010 (the "2011 10-K"), as amended by Amendment No. 1 to the 2011 10-K, filed with the SEC on January 30, 2012, have not materially changed since we filed that report. Our borrowing arrangements are more fully described in Note 8 of the Notes to Consolidated Financial Statements contained in Part 1, Item 1 in this Quarterly Report on Form 10-Q.

OFF-BALANCE SHEET ARRANGEMENTS

We have no material off-balance sheet arrangements as defined in SEC Regulation S-K- 303(a)(4)(ii).

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

We are subject to investment risk, interest rate risk, and foreign exchange rate risk as described below.

Investment and Interest Rate Risk

Our exposure to interest rate and general market risks relates principally to our investment portfolio, which as of December 30, 2011 consisted of the following (in thousands):

Cash and cash equivalents (time deposits and money market funds)	$	445,636
Restricted cash (time deposits and certificates of deposit)	862
Available for sale securities (auction rate securities)	2,288
	$	448,786

The main objective of our investment activities is the liquidity and preservation of capital. In general, our cash and cash equivalent investments have short-term maturity periods which dampen the impact of significant market or interest rate risk. Credit risk associated with our investments is not material as our investment policy prescribes high credit quality standards and limits the amount of credit exposure to any one issuer. We currently do not use derivative instruments for trading, speculative or investment purposes; however, we may use derivatives in the future.

We are subject to overall financial market risks, such as changes in market liquidity, credit quality and interest rates. Securities that are available for sale carry a longer maturity period (contractual maturities exceed ten years).

We do not believe that investment or interest rate risk is material to our business or results of operations.

17

Exchange Rate Risk

Substantially all sales to customers and arrangements with third-party manufacturers provide for pricing and payment in United States dollars, thereby reducing the impact of foreign exchange rate fluctuations on our results. A small percentage of our international operational expenses are denominated in foreign currencies. Exchange rate volatility could negatively or positively impact those operating costs. Increases in the value of the United States dollar relative to other currencies could make our products more expensive, which could negatively impact our ability to compete. Conversely, decreases in the value of the United States dollar relative to other currencies could result in our suppliers raising their prices to continue doing business with us. Fluctuations in currency exchange rates could have a greater effect on our business in the future to the extent our expenses increasingly become denominated in foreign currencies.

Item 4. Controls and Procedures.

Evaluation of disclosure controls and procedures.

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of December 30, 2011. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on management’s evaluation of our disclosure controls and procedures as of December 30, 2011, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in internal controls over financial reporting.

There are no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that occurred during the period covered by this report that have materially affected or are reasonable likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, various lawsuits, claims and proceedings have been, and may in the future be, instituted or asserted against the Company, including those pertaining to patent infringement, intellectual property, environmental, product liability, safety and health, employment and contractual matters.

Additionally, the semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights. From time to time, third parties have asserted and may in the future assert patent, copyright, trademark and other intellectual property rights to technologies that are important to our business and have demanded and may in the future demand that we license their technology. The outcome of any such litigation cannot be predicted with certainty and some such lawsuits, claims or proceedings may be disposed of unfavorably to the Company. Generally speaking, intellectual property disputes often have a risk of injunctive relief, which, if imposed against the Company, could materially and adversely affect the Company's financial condition, or results of operations. From time to time we are also involved in legal proceedings in the ordinary course of business.

On June 6, 2011, a putative stockholder class action lawsuit was filed in California Superior Court in Santa Clara County (Case No. 111CV202403) (the “Bushansky action”) naming AATI, the members of AATI's board of directors, the Company and Merger Sub as defendants. The complaint alleges, among other things, (1) that the members of AATI's board of directors breached their fiduciary duties by (a) failing to take steps to maximize the value of the merger consideration to AATI's stockholders, (b) taking steps to avoid competitive bidding, and (c) failing to protect against conflicts of interest resulting from change-of-control and transaction-related benefits received by AATI directors in connection with the merger that are not available to all stockholders, and (2) that AATI, the members of AATI's board of directors, the Company and Merger Sub aided and abetted these purported

18

breaches of fiduciary duties. The complaint seeks to enjoin consummation of the merger or, if the merger is completed, to recover damages caused by the alleged breaches of fiduciary duties. The complaint also seeks recovery of attorney's fees and costs of the lawsuit.

On June 7, 2011, a putative stockholder class action lawsuit was filed in California Superior Court in Santa Clara County (Case No. 111CV202501) (the “Venette action”) naming AATI, the members of AATI's board of directors, the Company and Merger Sub as defendants. Plaintiffs filed an amended complaint on July 14, 2011 (the “Amended Complaint”). The Amended Complaint alleges, among other things, (1) that the members of AATI's board of directors breached their fiduciary duties by (a) agreeing to the merger for inadequate consideration on unfair terms, (b) failing to protect against conflicts of interest resulting from change-of-control and transaction-related benefits received by AATI directors in connection with the merger that are not available to all stockholders, (c) selling the company in response to alleged pressure from Dialectic Capital Partners, LP (“Dialectic”), (d) taking steps to avoid competitive bidding (including the entry by certain AATI officers and directors into agreements with the Company relating to voting commitments and inclusion in the merger agreement of non-solicitation provisions and a termination fee), and (e) by causing the issuance of a materially misleading Form S-4 Registration Statement which, inter alia, purportedly fails to disclose material facts surrounding (i) Dialectic's impact on the proposed merger process, (ii) the AATI board of directors' evaluation of the Company and its offer for AATI, and (iii) supporting figures and analysis regarding the fairness opinion that the AATI Board obtained from its financial advisor, Needham & Company, LLC, in connection with the transaction and (2) that AATI, the members of AATI's board of directors, the Company and Merger Sub aided and abetted these purported breaches of fiduciary duties. The Amended Complaint seeks to enjoin consummation of the merger, and to have the court direct the defendants to implement procedures and processes to maximize shareholder value. The Amended Complaint also seeks recovery of attorney's fees and costs of the lawsuit.

On July 26, 2011, the Court issued an order consolidating the Bushansky action and Venette action into a single, consolidated action captioned In re Advanced Analogic Technologies Inc. Shareholder Litigation, Lead Case No. 111CV202403, and designating the Amended Complaint as the operative complaint in the litigation. The Company believes that the claims in the consolidated action are without merit and intends to defend against such claims vigorously.

We believe that there is no other pending litigation involving the Company that will have, individually or in the aggregate, a material adverse effect on our business.

FY12 Executive Incentive Plan

1. Purpose: The FY12 Executive Incentive Plan (the”FY12 Plan”) is designed to reward key management employees for achieving certain financial and business objectives.

2. Plan Period: The FY12 Plan covers the period from October 1, 2011 through September 28, 2012.

3. Eligibility: This program applies to the Chief Executive Officer and his direct reporting senior executives. Other key employees may be added based upon the recommendation of the Chief Executive Officer and subsequent approval of the Compensation Committee. Those employees not covered by this plan may be eligible for other programs established by Skyworks.

4. Incentive Targets: Participants are eligible to earn a percentage of their base salary for attaining certain performance objectives. Nominal, target and stretch incentive awards have been established as follows (shown as a percentage of the participant's base salary):

Name	Incentive At Nominal	Incentive At Target	Incentive At Stretch
CEO	62.5%	125%	250%
CFO, FES BU General Manager, HPA BU General Manager	37.5%	75%	150%
VP Sales, VP Ops	35%	70%	140%
Other VPs	27.5%	55%	110%
Special Participants	20%	40%	80%

5. FY12 Metrics: The performance metrics for FY12 are as follows:

1^st Half Financial

Metric	Nominal	Target	Stretch
Revenue	REDACTED	REDACTED	REDACTED
Gross Margin %1	REDACTED	REDACTED	REDACTED

² Before incentive

³ Includes CEO, CFO, VP General Counsel, VP HR, VP Quality, VP Corp Dev

Performance periods are semi-annual. The individual metrics above are for normal operations and any extraordinary events and/or charges will be brought to the Compensation Committee for review and approval. Metrics will be weighted based on performance for the first and second half of FY12 as follows:

1^st Half

Division	Revenue	GM%	OI%	Customer Satisfaction	BU Revenue	BU OI%	Product Development3
REDACTED	n/a	n/a	20%	n/a	30%	25%	25%

¹ Combined REDACTED

² Includes CEO, CFO, VP General Counsel, VP HR, VP Quality, VP Corp Dev

³ Based on number of achievements

6. How the Plan Works: Upon completion of the first six months of the Fiscal Year, the Chief Executive Officer will provide the Compensation Committee with recommendations for incentive award payments to the named participants of the plan. The Committee will review the recommendations and approve the actual amount to be paid to each participant. The Committee will rely upon the CEO for the appropriate distribution of the authorized incentive pool. The same process will occur for the 2nd 6 months of the Fiscal Year. All incentive award payments under the FY12 Plan, if earned, will be paid by March 15th of the calendar year following the end of the fiscal year in which the performance occurs.

7. Administration: Actual performance between the Nominal and Target metrics will be paid on a linear sliding scale beginning at the Nominal percentage and moving up to the Target percentage. The same linear scale will apply for performance between Target and Stretch metrics. In order to fund the incentive plans and insure the overall Company's financial performance, the following terms apply.

• No incentive award will be paid unless the Company meets its Nominal operating income margin goal after accounting for any incentive award payments.

• Payout for the first six month performance period will be capped at 80% of earnings with 20% being held back until the end of the fiscal year based on sustained performance.

• Incentive payments will be processed in a timely manner at the completion of each six month performance period. Skyworks' CEO, subject to approval by the Compensation Committee, retains discretion to award below nominal or above Stretch and to modify all individual incentive payments to ensure equitable distribution of incentives; such modifications may include, but are not limited to, the delivery of equity or similar instruments in lieu of cash payments.

• Any payout shall be conditioned upon the Participant's employment by the Company on the date of payment; provided, however, that the Compensation Committee may make exceptions to this requirement, in its sole discretion, including, without limitation, in the case of a participant's termination of employment, retirement, death or disability.

8. Taxes: All awards are subject to federal, state, local and social security taxes. Payments under this Plan will not affect the base salary, which is used as the basis for Skyworks' benefits program.

9. Amendments: The Company reserves the right to amend or terminate the FY12 Plan at any time in its sole discretion.

FAIR VALUE

In accordance with ASC 820 - Fair Value Measurements and Disclosure (“ASC 820”), the Company groups its financial assets and liabilities measured at fair value on a recurring basis in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:

Level 1 - Valuation is based upon quoted market price for identical instruments traded in active markets.

Level 2 - Valuation is based upon quoted market prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3 - Valuation is generated from model-based techniques that use significant assumptions not observable in the market. Valuation techniques include use of discounted cash flow models and similar techniques.

The Company has cash equivalents classified as Level 1 and has no Level 2 securities. The Company's ARS, discussed in Note 3, Marketable Securities, are classified as Level 3 assets. There have been no transfers between Level 1, Level 2 or Level 3 assets or liabilities during the three months endedDecember 30, 2011. There have been no purchases, sales, issuances or settlements of the marketable securities classified as Level 3 assets during the three months endedDecember 30, 2011. The Company has classified its contingent consideration recorded for business combinations as a Level 3 liability. The Company reassessed the fair value of the contingent consideration and determined that there was no change during the three months endedDecember 30, 2011.

Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis

The Company measures certain financial assets and liabilities at fair value on a recurring basis such as our financial instruments, marketable securities and contingent consideration related to business combinations.

As of December 30, 2011, the financial assets and liabilities measured on a recurring basis at fair value consist of the following (in thousands):                         

			Fair Value Measurements
	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Liabilities
Contingent consideration liability recorded for business combinations	$	59,400	$	—	$	—	$	59,400

Non-Financial Assets Measured and Recorded at Fair Value on a Nonrecurring Basis

The Company's non-financial assets and liabilities, such as goodwill, intangible assets, and other long lived assets resulting from business combinations are measured at fair value at the date of acquisition and subsequently re-measured if there is an indicator of impairment. There were no indicators of impairment identified during the three months endedDecember 30, 2011.

Business Description and Basis of Presentation

DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Skyworks Solutions, Inc. together with its consolidated subsidiaries, (“Skyworks” or the “Company”) is an innovator of high reliability analog and mixed signal semiconductors. Leveraging core technologies, Skyworks offers diverse standard and custom linear products supporting automotive, broadband, cellular infrastructure, energy management, industrial, medical, military and cellular handset applications. The Company's portfolio includes amplifiers, attenuators, circulators, detectors, diodes, directional couplers, front-end modules, hybrids, infrastructure RF subsystems, isolators, mixers/demodulators, optocouplers, optoisolators, phase shifters, PLLs/synthesizers/VCOs, power dividers/combiners, receivers, switches and technical ceramics.

The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Certain information and footnote disclosures, normally included in annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), have been condensed or omitted pursuant to those rules and regulations. However, in management's opinion, the financial information reflects all adjustments, including those of a normal recurring nature necessary to present fairly the financial position, results of operations, and cash flows of the Company for the periods presented. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year. This information should be read in conjunction with the Company's financial statements and notes thereto contained in the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2011, filed with the SEC on November 28, 2010 (the "2011 10-K"), as amended by Amendment No. 1 to the 2011 10-K, filed with the SEC on January 30, 2012.

The Company evaluates its estimates on an ongoing basis using historical experience and other factors, including the current economic environment. Significant judgment is required in determining the reserves for and fair value of items such as inventory, income taxes, share-based compensation, loss contingencies, bad debts, contingent consideration associated with business combinations, and overall fair value assessments of assets and liabilities. In addition, significant judgment is required in determining whether a potential indicator of impairment of long-lived assets exists and in estimating future cash flows for any necessary impairment tests. Management's estimates could differ significantly from actual results.

The Company has evaluated subsequent events through the date of issuance of these unaudited consolidated financial statements.

The Company's fiscal year ends each year on the Friday closest to September 30. Fiscal 2012 consists of 52 weeks and ends on September 28, 2012. Fiscal 2011 consisted of 52 weeks and ended on September 30, 2011. The first quarters of fiscal 2012 and fiscal 2011 each consisted of 13 weeks and ended on December 30, 2011 and December 31, 2010, respectively.

Acquisitions

BUSINESS COMBINATIONS

On January 10, 2012, the Company acquired all of the outstanding shares of Advanced Analogic Technologies, Incorporated ("AATI") for a total purchase price of approximately $200.0 million in cash, net of cash acquired. AATI is an analog semiconductor company focused on enabling energy-efficient devices for consumer electronics, computing and communications markets. This acquisition expands Skyworks’ portfolio with highly complementary analog semiconductor products including battery chargers, DC/DC converters, voltage regulators and LED drivers. Due to the timing of the acquisition and its proximity to the filing date of this Quarterly Report on Form 10-Q, the Company has omitted the majority of the disclosures required under ASC 805 - Business Combinations ("ASC 805")as the initial accounting is incomplete.

Segment Information

SEGMENT INFORMATION AND CONCENTRATIONS

In accordance with ASC 280-Segment Reporting ("ASC 280"), the Company has one reportable operating segment which designs, develops, manufactures and markets proprietary semiconductor products, including intellectual property. ASC 280 establishes standards for the way public business enterprises report information about operating segments in annual financial statements and in interim reports to shareholders. The method for determining what information to report is based on management's use of financial information for the purposes of assessing performance and making operating decisions. In evaluating financial performance and making operating decisions, management primarily uses consolidated net revenue, gross profit, operating profit and earnings per share. The Company's business units share similar economic characteristics, long term business models, research and development expenses and selling, general and administrative expenses. The Company continues to consider itself to have one reportable operating segment at December 30, 2011. The Company will re-assess its conclusions at least annually.

COMMITMENTS AND CONTINGENCIES

Legal Matters

From time to time, various lawsuits, claims and proceedings have been, and may in the future be, instituted or asserted against the Company, including those pertaining to patent infringement, intellectual property, environmental, product liability, safety and health, employment and contractual matters.

Additionally, the semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights. From time to time, third parties have asserted and may in the future assert patent, copyright, trademark and other intellectual property rights to technologies that are important to the Company's business and have demanded and may in the future demand that the Company license their technology. The outcome of any such litigation cannot be predicted with certainty and some such lawsuits, claims or proceedings may be disposed of unfavorably to the Company. Generally speaking, intellectual property disputes often have a risk of injunctive relief, which, if imposed against the Company, could materially and adversely affect the Company's financial condition, or results of operations. From time to time the Company may also be involved in legal proceedings in the ordinary course of business.

On June 6, 2011, a putative stockholder class action lawsuit was filed in California Superior Court in Santa Clara County (Case No. 111CV202403) (the “Bushansky action”) naming AATI, the members of AATI's board of directors, the Company and Merger Sub as defendants. The complaint alleges, among other things, (1) that the members of AATI's board of directors breached their fiduciary duties by (a) failing to take steps to maximize the value of the merger consideration to AATI's stockholders, (b) taking steps to avoid competitive bidding, and (c) failing to protect against conflicts of interest resulting from change-of-control and transaction-related benefits received by AATI directors in connection with the merger that are not available to all stockholders, and (2) that AATI, the members of AATI's board of directors, the Company and Merger Sub aided and abetted these purported breaches of fiduciary duties. The complaint seeks to enjoin consummation of the merger or, if the merger is completed, to recover damages caused by the alleged breaches of fiduciary duties. The complaint also seeks recovery of attorney's fees and costs of the lawsuit.

On June 7, 2011, a putative stockholder class action lawsuit was filed in California Superior Court in Santa Clara County (Case No. 111CV202501) (the “Venette action”) naming AATI, the members of AATI's board of directors, the Company and Merger Sub as defendants. Plaintiffs filed an amended complaint on July 14, 2011 (the “Amended Complaint”). The Amended Complaint alleges, among other things, (1) that the members of AATI's board of directors breached their fiduciary duties by (a) agreeing to the merger for inadequate consideration on unfair terms, (b) failing to protect against conflicts of interest resulting from change-of-control and transaction-related benefits received by AATI directors in connection with the merger that are not available to all stockholders, (c) selling the company in response to alleged pressure from Dialectic Capital Partners, LP (“Dialectic”), (d) taking steps to avoid competitive bidding (including the entry by certain AATI officers and directors into agreements with the Company relating to voting commitments and inclusion in the merger agreement of non-solicitation provisions and a termination fee), and (e) by causing the issuance of a materially misleading Form S-4 Registration Statement which, inter alia, purportedly fails to disclose material facts surrounding (i) Dialectic's impact on the proposed merger process, (ii) the AATI board of directors' evaluation of the Company and its offer for AATI, and (iii) supporting figures and analysis regarding the fairness opinion that the AATI Board obtained from its financial advisor, Needham & Company, LLC, in connection with the transaction and (2) that AATI, the members of AATI's board of directors, the Company and Merger Sub aided and abetted these purported breaches of fiduciary duties. The Amended Complaint seeks to enjoin consummation of the merger, and to have the court direct the defendants to implement procedures and processes to maximize shareholder value. The Amended Complaint also seeks recovery of attorney's fees and costs of the lawsuit.

On July 26, 2011, the Court issued an order consolidating the Bushansky action and Venette action into a single, consolidated action captioned In re Advanced Analogic Technologies Inc. Shareholder Litigation, Lead Case No. 111CV202403, and designating the Amended Complaint as the operative complaint in the litigation. The Company believes that the claims in the consolidated action are without merit and intends to defend against such claims vigorously.

The Company believes that there is no other pending litigation involving the Company that will have, individually or in the aggregate, a material adverse effect on the business.

Guarantees and Indemnifications

The Company has made no contractual guarantees for the benefit of third parties. However, the Company generally indemnifies its customers from third-party intellectual property infringement litigation claims related to its products, and, on occasion, also provides other indemnities related to product sales. In connection with certain facility leases, the Company has indemnified its lessors for certain claims arising from the Company's activities at the facility or out of the lease.

The Company indemnifies its directors and officers to the maximum extent permitted under the laws of the state of Delaware. The duration of the indemnities varies, and in many cases is indefinite. The indemnities to customers in connection with product sales generally are subject to limits based upon the amount of the related product sales and in many cases are subject to geographic and other restrictions. In certain instances, the Company's indemnities do not provide for any limitation of the maximum potential future payments the Company could be obligated to make. The Company has not recorded any liability for these indemnities in the accompanying consolidated balance sheets and does not expect that such obligations will have a material adverse impact on its financial condition or results of operations.

BORROWING ARRANGEMENTS

LONG-TERM DEBT        

On March 2, 2007, the Company issued $200.0 million aggregate principal amount of convertible subordinated notes ("2007 Convertible Notes"). The offering contained two tranches. The first tranche consisted of $100.0 million of 1.25% convertible subordinated notes due March 2010 (the "1.25% Notes") which have been retired. The second tranche consisted of $100.0 million aggregate principal amount of 1.50% convertible subordinated notes due March 2012 (the "1.50% Notes"). During the three months endedDecember 30, 2011, the Company redeemed and retired $9.4 million of aggregate principal amount of the 1.50% Notes, paying a cash premium of $5.6 million which was accounted for as a reacquisition of equity instruments in accordance with ASC 470-20 - Debt, Debt with Conversions and Other Options ("ASC 470-20"). As of December 30, 2011, the remaining aggregate principal amount of the 1.50% Notes was $17.3 million, which the Company redeemed and retired subsequent to the Balance Sheet date for total cash paid of $32.8 million (including premium).

On October 3, 2009, the Company adopted ASC 470-20 which requires the issuer of convertible debt instruments with cash settlement features to separately account for the liability and equity components of the convertible debt instrument and requires retrospective application to all periods presented in the financial statements to which it is applicable. ASC 470-20 applies to the Company's 2007 Convertible Notes. Using a non-convertible borrowing rate of 6.86%, the Company estimated the fair value of the liability component of the $100.0 million aggregate principal amount of the 1.50% Notes to be $77.3 million as of October 3, 2009. As of the issuance date, the difference between the fair value of the liability component of the 1.50% Notes and the corresponding aggregate principal amount of such notes, which is equal to the fair value of the equity component of the 1.50% Notes, $22.7 million, was retrospectively recorded as a debt discount and as an increase to additional paid-in capital, net of tax. The remaining unamortized discount of the liability component of the 1.50% Notes was written off in January 2012 to correspond with the retirement of the remaining outstanding aggregate principal amount of the 1.50% Notes.

The following tables provide additional information about the Company's 2007 Convertible Notes (in thousands):

Income Tax Expense (Benefit) [Abstract]

Income Taxes

INCOME TAXES

The Company recorded income tax provisions of $17.5 million and $15.9 million for the three months endedDecember 30, 2011 and December 31, 2010, respectively. The provision for income taxes for the three months endedDecember 30, 2011 consisted of $15.5 million and $2.0 million of United States and foreign income taxes, respectively, as compared to $15.2 million and $0.7 million for United States and foreign income taxes, respectively, for the three months endedDecember 31, 2010.

For the three months ended December 30, 2011 and December 31, 2010, the difference between the Company's effective tax rate and the 35% U.S. federal statutory rate resulted primarily from foreign earnings taxed at rates lower than the federal statutory rate, the recognition of research and development tax credits earned, and the domestic production activities deduction, partially offset by an increase in our tax expense related to a change in our reserve for uncertain tax positions. In December 2010, the United States Congress enacted legislation to retroactively extend the federal research and development tax credit. As a result, the Company recognized $4.4 million of federal research and development tax credits in the three months endedDecember 31, 2010, which were earned in the fiscal year ended October 1, 2010.

On October 2, 2010, the Company expanded its presence in Asia by launching operations in Singapore. The Company operates under a tax holiday in Singapore, which is effective through September 30, 2020. The tax holiday is conditional upon the Company's compliance with meeting certain employment and investment thresholds in Singapore.

In accordance with GAAP, management has determined that it is more likely than not that a portion of the Company's historic and current year income tax benefits will not be realized. Accordingly, as of December 30, 2011, the Company has maintained a valuation allowance of $39.4 million. This valuation allowance is comprised of $26.1 million related to U.S. state tax credits and $13.3 million related to the Company's foreign deferred tax assets of which $11.6 million were acquired from SiGe in fiscal 2011.

Realization of benefits from the Company's deferred tax assets, net of valuation allowance, is dependent upon generating United States source taxable income in the future. The existing valuation allowance could be reversed in the future to the extent that the related deferred tax assets no longer require a valuation allowance under the provisions of ASC 740 - Income Taxes ("ASC 740").

The Company will continue to evaluate its valuation allowance in future periods and depending upon the outcome of that assessment, additional amounts could be reversed or recorded and recognized as an adjustment to income tax benefit or expense. Such adjustments could cause the Company's effective income tax rate to vary in future periods. The Company will need to generate $231.1 million of United States federal taxable income in future years to utilize all of the Company's net operating loss carryforwards, research and experimentation tax credit carryforwards, and deferred income tax temporary differences, net of valuation allowance, as of December 30, 2011.

During the three months ended December 30, 2011, the Company increased its gross unrecognized tax benefits by $3.9 million to $36.0 million. Of the total unrecognized tax benefits at December 30, 2011, $23.9 million would impact the effective tax rate, if recognized. The remaining unrecognized tax benefits would not impact the effective tax rate, if recognized, due to the Company's valuation allowance and certain positions which were required to be deferred. There are no positions that the Company anticipates could change within the next twelve months. The Company incurred $0.1 million of interest related to unrecognized tax benefits during the three months ended December 30, 2011. The Company's policy is to recognize accrued interest and penalties, if incurred, on any unrecognized tax benefits as a component of income tax expense.
