DIODES INCORPORATED AND SUBSIDIARIES

NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

(Unaudited)

NOTE A – Nature of Operations, Basis of Presentation and Recently Issued Accounting Pronouncements

Nature of Operations

Diodes Incorporated and its subsidiaries (collectively, the “Company”) is a leading global manufacturer and supplier of high-quality, application specific standard products within the broad discrete, logic and analog semiconductor markets, serving the consumer electronics, computing, communications, industrial and automotive markets throughout Asia, North America and Europe.

Basis of Presentation

The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S.”) (“GAAP”) for interim financial information and with the instructions to Form 10-Q. They do not include all information and footnotes necessary for a fair presentation of financial position, results of operations and cash flows in conformity with U.S. GAAP for complete financial statements. These consolidated condensed financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011. All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the results of operations for the period presented have been included in the interim period. Operating results for the three months ended March 31, 2012 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2012. The consolidated condensed financial data at December 31, 2011 is derived from audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. As permitted under U.S. GAAP, interim accounting for certain expenses, including income taxes, are based on full year forecasts. Such amounts are expensed in full in the year incurred. For interim financial reporting purposes, income taxes are recorded based upon estimated annual effective income tax rates.

Certain prior year’s balances have been reclassified to conform to the current financial statement presentation.

Recently Issued Accounting Pronouncements

There have been no new accounting pronouncements during the three months ended March 31, 2012, as compared to recently issued accounting pronouncements described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011, that are of significance, or potential significance, to the Company.

During the first quarter of 2012, the Company adopted Accounting Standards Update (“ASU”) No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. ASU No. 2011-05 requires an other comprehensive income statement to be included with the income statement, which together will make a statement of total comprehensive income, or separate from the income statement, but the two statements will have to appear consecutively within a financial report. The Company elected to present other comprehensive income as a separate statement from the income statement.

NOTE B – Earnings Per Share

Basic earnings per share is calculated by dividing net earnings by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is calculated similarly but includes potential dilution from the exercise of stock options and stock awards, except when the effect would be anti-dilutive.

The computation of basic and diluted earnings per common share is as follows (in thousands, except per share data):

		$xxxxxxxxxx		$xxxxxxxxxx
	Three Months Ended
	March 31,
	2012		2011

Net income attributable to common stockholders	$	4,871	$	19,684
Earnings per share attributable to common stockholders	$	0.10	$	0.42

NOTE C – Inventories

NOTE E – Fair Value Measurements

As of March 31, 2012, the Company held approximately 13 million shares, approximately 30 percent ownership, of the common stock of Eris Technology Corporation (“Eris”), a publicly traded company listed as an Emerging Stock on the Taiwan OTC Exchange (TWO) that provides design, manufacturing and after-market services for diode products. See Note K for additional information regarding related party transactions with Eris.

The Company has elected the fair value option for the shares of Eris common stock, which the unrealized gains and losses are reported in other income (expense). Fair value is the price that would be received on the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The shares of Eris common stock are valued under the fair value hierarchy as a Level 1 Input, which is the quoted price (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Financial assets carried at fair value as of March 31, 2012 are classified in the following table (in thousands):

			Fair Value Measurements						Changes in Fair Values for Items Measured at Fair Value  Pursuant to Election of the Fair Value Option
Description	Fair Value Estimate		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Other Gains and (Losses)			Total Changes in Fair Values Included in Current-Period Earnings
Securities carried at fair value *	$	13,740	$	13,740	$	—	$	—	$	(650	)	$	389

* Represents investments that would otherwise be accounted for under the equity method of accounting and is included in other assets.

NOTE F – Income Tax Provision

Income tax expense of approximately $1 million and $5 million was recorded for the three months ended March 31, 2012 and 2011, respectively. This resulted in an effective tax rate of 10% for the three months ended March 31, 2012, as compared to 19% in the same period last year and compared to 16% for the full year of 2011. Our effective tax rates for the three months ended March 31, 2012 and 2011, respectively, were lower than the U.S. statutory tax rate of 35%, principally from the impact of higher income in lower-taxed jurisdictions.

For the three months ended March 31, 2012, the Company reported domestic and foreign pre-tax income (loss) of approximately $(7) million and $13 million, respectively. For the three months ended March 31, 2011, the Company reported domestic and foreign pre-tax income (loss) of approximately $(6) million and $31 million, respectively. Funds repatriated from foreign subsidiaries to the U.S. may be subject to federal and state income taxes. The Company intends to permanently reinvest overseas all of its earnings from its foreign subsidiaries; accordingly, U.S. taxes are not being recorded on undistributed foreign earnings.

The impact of tax holidays decreased the Company’s tax expense by approximately $2 million for the three months ended March 31, 2012 and 2011. The benefit of the tax holidays on both basic and diluted earnings per share for the three months ended March 31, 2012 was approximately $0.04. The benefit of the tax holidays on both basic and diluted earnings per share for the three months ended March 31, 2011 was approximately $0.05.

The Company files income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. The Company is no longer subject to U.S. federal income tax examinations by tax authorities for tax years before 2007. With respect to state and local jurisdictions and countries outside of the U.S., with limited exceptions, the Company is no longer subject to income tax audits for years before 2006. Although the outcome of tax audits is always uncertain, the Company believes that adequate amounts of tax, interest and penalties, if any, have been provided for in the Company’s reserve for any adjustments that may result from future tax audits. The Company recognizes accrued interest and penalties, if any, related to unrecognized tax benefits in income tax expense. As of March 31, 2012, the gross amount of unrecognized tax benefits was approximately $10 million.

It is reasonably possible that the amount of the unrecognized benefit with respect to certain of the Company’s unrecognized tax positions will significantly increase or decrease within the next 12 months. These changes may be the result of settlements of ongoing audits or competent authority proceedings. At this time, an estimate of the range of the reasonably possible outcomes cannot be made.

NOTE G – Share-Based Compensation

The following table shows the total compensation expensed for share-based compensation plans, including stock options and share grants, recognized in the statements of operations (in thousands):

	Three Months Ended March 31,
	2012		2011
Cost of sales	$	103	$	86
Selling and administrative expense		3,126		2,868
Research and development expense		316		230
Total share-based compensation expense	$	3,545	$	3,184

Stock Options. Stock options generally vest in equal annual installments over a four-year period and expire ten years after the grant date, and expense was estimated on the date of grant using the Black-Scholes option pricing model.

The total net cash proceeds received from stock option exercises during the three months ended March 31, 2012 was approximately $0 million. Stock option expense for both the three months ended March 31, 2012 and 2011 was approximately $1 million.

- 11 -

A summary of the stock option plans is as follows:

Stock Options	Shares (000)			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (yrs)		Aggregate Intrinsic Value ($000)
Outstanding at January 1, 2012		3,587		$	16.69		5	$	22,299
Granted		12			21.83
Exercised		(62	)		7.51				1,066
Forfeited or expired		—			—
Outstanding at March 31, 2012		3,537		$	16.86		5	$	26,218
Exercisable at March 31, 2012		2,560		$	14.69		4	$	23,111

The aggregate intrinsic value in the table above is before applicable income taxes and represents the amount option holders would have received if all options had been exercised on the last business day of the period indicated, based on the Company’s closing stock price.

As of March 31, 2012, total unrecognized stock-based compensation expense related to unvested stock options, net of forfeitures, was approximately $9 million, before income taxes, and is expected to be recognized over a weighted average period of approximately 2 years.

Share Grants. Restricted stock awards and restricted stock units generally vest in equal annual installments over a four-year period.

The total fair value of restricted stock awards vested during the three months ended March 31, 2012 was approximately $1 million. Share grant expense for both the three months ended March 31, 2012 and 2011 was approximately $2 million.

A summary of the Company’s non-vested share grants is as follows:

Share Grants	Shares (000)			Weighted- Average Grant-Date Fair Value		Aggregate Intrinsic Value ($000)
Non-vested at January 1, 2012		623		$	22.91	$	14,279
Granted		8			21.83
Vested		(9	)		23.83		210
Forfeited		(6	)		23.00
Non-vested at March 31, 2012		616		$	22.88	$	14,104

As of March 31, 2012, total unrecognized share-based compensation expense related to non-vested stock awards, net of forfeitures, was approximately $20 million, before income taxes, and is expected to be recognized over a weighted average period of approximately 3 years.

The net pension and supplemental retirement benefit obligations and the related periodic costs are based on, among other things, assumptions regarding the discount rate, estimated return on plan assets and mortality rates. These obligations and related periodic costs are measured using actuarial techniques and assumptions. The projected unit credit method is the actuarial cost method used to compute the pension liabilities and related expenses.

For the three months ended March 31, 2012, net period benefit costs associated with the defined benefit plan were approximately $0 million.

The following tables set forth the benefit obligation, the fair value of plan assets, and the funded status of the Company’s plan (in thousands):

	Defined Benefit Plan
Change in benefit obligation:
Balance at December 31, 2011	$	109,877
Service cost		78
Interest cost		1,397
Actuarial gain		3,849
Benefits paid		(977	)
Currency changes		3,207
Benefit obligation at March 31, 2012	$	117,431
Change in plan assets:
Fair value of plan assets at December 31, 2011	$	96,384
Actual return on plan assets		2,254
Employer contribution		1,089
Benefits paid		(977	)
Currency changes		2,774
Fair value of plan assets at March 31, 2012	$	101,524
Underfunded status at March 31, 2012	$	(15,907	)

Based on an actuarial study performed as of March 31, 2012, the plan is underfunded and a liability is reflected in the Company’s consolidated financial statements as a long-term liability. The weighted-average discount rate assumption used to determine benefit obligations as of March 31, 2012 was 5.1%.

- 14 -

The following are weighted-average assumptions used to determine net periodic benefit costs for the three months ended March 31, 2012:

Discount rate	5.1	%
Expected long-term return on plan assets	5.6	%

The Company adopted a payment plan with the trustees of the defined benefit plan, in which the Company paid approximately £1.0 million GBP (approximately $1.6 million based on a USD:GBP exchange rate of 1.6:1) every year from 2009 through 2011. The Company and the trustees are in discussions regarding the payment scheme.

The Company also has pension plans in Asia for which the benefit obligation, fair value of the plan assets and the funded status amounts are deemed immaterial and therefore, are not included in the figures or assumptions above.

Deferred Compensation

The Company maintains a Non-Qualified Deferred Compensation Plan (the “Deferred Compensation Plan”) for executive officers, key employees and members of the Board of Directors (the “Board”). The Deferred Compensation Plan allows eligible participants to defer the receipt of eligible compensation, including equity awards, until designated future dates. The Company offsets its obligations under the Deferred Compensation Plan by investing in the actual underlying investments. These investments are classified as trading securities and are carried at fair value. At March 31, 2012, these investments totaled approximately $3 million. All gains and losses in these investments are materially offset by corresponding gains and losses in the Deferred Compensation Plan liabilities.

NOTE K – Related Parties

The Company conducts business with a related party company, Lite-On Semiconductor Corporation and its subsidiaries and affiliates (collectively, “LSC”), that owned approximately 18% of the Company’s outstanding Common Stock as of March 31, 2012. The Company also conducts business with one significant company, Keylink International (B.V.I.) Inc. and its subsidiaries and affiliates (collectively, “Keylink”). Keylink is the Company’s 5% joint venture partner in the Company’s Shanghai manufacturing facilities. In addition, the Company conducts business with a related party company, Eris. The Company owned approximately 30% of Eris’s outstanding Common Stock as of March 31, 2012.

The Audit Committee of the Company’s Board reviews all related party arrangements for potential conflict of interest situations on an ongoing basis, in accordance with such procedures as the Audit Committee may adopt from time to time.

Lite-On Semiconductor Corporation – During both the three months ended March 31, 2012 and 2011, the Company sold products to LSC totaling approximately 0% and 1% of its net sales, respectively. Net sales have decreased in recent years due to fewer wafers being sold to LSC and more wafers being used for internal consumption. Also, for the three months ended March 31, 2012 and 2011, approximately 3% and 6%, respectively, of the Company’s net sales were from semiconductor products purchased from LSC for subsequent sale, making LSC one of the Company’s largest suppliers.

Net sales to, and purchases from, LSC are as follows (in thousands):

	Three Months Ended
	March 31,
	2012		2011
Net sales	$	47	$	447
Purchases	$	7,418	$	9,392

Keylink International (B.V.I.) Inc. – During the three months ended March 31, 2012 and 2011, the Company sold products to Keylink totaling approximately 3% and 1% of its net sales, respectively. Net sales increased in 2012 compared to 2011 due to the renewed business activity that had ceased during most of 2011. Also, for both the three months ended March 31, 2012 and 2011, approximately 1% of the Company’s net sales were from semiconductor products purchased from Keylink for subsequent sale. In addition, the Company’s subsidiaries in China lease their manufacturing facilities from, and subcontract a portion of their manufacturing process (including, but not limited to, metal plating and environmental services) to Keylink.

Overview

We are a leading global manufacturer and supplier of high-quality, application specific standard products within the broad discrete, logic and analog semiconductor markets, serving the consumer electronics, computing, communications, industrial and automotive markets. The products are sold primarily throughout Asia, North America and Europe.

We design, manufacture and market these semiconductors for diverse end-use applications. Semiconductors, which provide electronic signal amplification and switching functions, are basic building-block electronic components that are incorporated into almost every electronic device. We believe that our focus on standard semiconductor products provides us with a meaningful competitive advantage relative to other semiconductor companies.

First Quarter 2012

Late in the first quarter of 2012, we began to see signs of a recovery in our end markets. We took advantage of this renewed strength by significantly reducing our lower margin finished goods inventory, which helped to support revenue and secure incremental market share gains. Overall, we reduced our finished goods inventory by 20% while channel inventory declined 3%. As a result, we achieved moderate sequential revenue growth, which is significantly better than the typical seasonal slowness. However, our decision to reduce inventory combined with the increased pricing pressure and lower utilization continued to impact margins during the quarter. We believe the first quarter represents the low point in the cycle and that overall demand is beginning to improve across all of our geographies. As such, we have shifted our strategy back to our growth model to aggressively capture additional market share. We have begun adding capacity for new, more advanced packaging at our Shanghai facilities to support our continued growth. As the demand and pricing environment improves further, we will transition available capacity to higher margin products to enhance our product mix and margins going forward.

- 17 -

Business Outlook

We expect continued growth in the second quarter, which is further evidence of the improvement in our business and the general economic conditions. The flexibility of our business model has allowed us to consistently deliver profitability, gain market share and even grow revenue during down economic cycles. We believe we are well positioned for growth and that our strategy will continue to produce growth rates that exceed our addressable markets. With further evidence of improvement in overall demand as well as our increased new project design win activity, we are returning to our growth model and expect revenue in the second quarter to range between $155 million and $164 million, or up 7% to 13% sequentially. We expect gross margin to be 26%, plus or minus 2.0%. Operating expenses, without consideration of any gain on sale of assets, are expected to be down slightly from first quarter on a percent of revenue basis. We expect our income tax rate to range between 7% and 13%, and shares used to calculate GAAP EPS for the second quarter are anticipated to be approximately 47.2 million.

Factors Relevant to Our Business

The following has affected, and, we believe, will continue to affect, our results of operations:

• Net sales for the three months ended March 31, 2012 was $145 million, compared to $162 million in the same period last year. This decrease in net sales mainly reflects the decrease in demand for our products in all geographic regions during the first three months of 2012 compared to the first three months of 2011.

• Our gross profit margin was 23% for the three months ended March 31, 2012, compared to 36% in the same period last year. Our gross margin percentage decreased over the same period last year due to a weaker pricing environment and lower utilization. Future gross profit margins will depend primarily on market prices, our product mix, manufacturing cost savings, and the demand for our products.

• For the three months ended March 31, 2012, our capital expenditures, excluding capital expenditures related to our investment agreement with the Management Committee of the Chengdu Hi-Tech Industrial Development Zone (the “CDHT”), were approximately 5% of our net sales, which is lower than our historical 10% to 12% of net sales model. For 2012, we expect capital expenditures, excluding capital expenditures related to our investment agreement, to be at the low end of our historical model.

• For the three months ended March 31, 2012 and 2011, the percentage of our net sales derived from our Asian subsidiaries was 77% and 73%, respectively. In the near future, we expect our percentage of net sales to the Asian market to remain approximately the same. Europe accounted for approximately 12% of our revenues for the three months ended March 31, 2012, compared to 15% in the same period last year. In addition, North America accounted for approximately 11% of our revenues for the three months ended March 31, 2012, compared to 12% in the same period last year.

• As of March 31, 2012, we had invested approximately $362 million in our manufacturing facilities in Asia. For the three months ended March 31, 2012, we invested approximately $15 million in these manufacturing facilities, and we expect to continue to invest in our manufacturing facilities, although the amount to be invested will depend on, among other factors, product demand and new product developments.

• For the three months ended March 31, 2012, our original equipment manufacturers (“OEM”) and electronic manufacturing services (“EMS”) customers together accounted for approximately 47% of our net sales, while our global network of distributors accounted for approximately 53% of our net sales.

The following discussion explains in greater detail our consolidated operating results and financial condition for the three months ended March 31, 2012, compared to the three months ended March 31, 2011. This discussion should be read in conjunction with the consolidated financial statements and notes thereto appearing elsewhere in this quarterly report (in thousands).

	2012		2011
Net Sales	$	144,663	$	161,555

Net sales decreased approximately $17 million for the three months ended March 31, 2012, compared to the same period last year. The 10% decrease in net sales was due to an approximately 21% decrease in average selling price (“ASP”) and a 13% increase in units sold. The revenue decrease for the three months ended March 31, 2012 was attributable to general market slowdown on a global basis, specifically in the consumer and computing markets, causing larger than normal pricing decline, coupled with a reduction in our subcontractor assembly test activity.

	2012			2011
Cost of goods sold	$	110,957		$	104,162
Gross profit	$	33,706		$	57,393
Gross profit margin		23	%		36	%

Cost of goods sold increased approximately $7 million, or 7%, for the three months ended March 31, 2012, compared to the same period last year. As a percent of sales, cost of goods sold increased to 77% for the three months ended March 31, 2012, compared to 64% in the same period last year, and our average unit cost (“AUP”) decreased 6% due to improved manufacturing costs.

For the three months ended March 31, 2012, gross profit decreased by approximately $24 million, or 41%, compared to the same period last year. Gross margin decreased to 23% for the three months ended March 31, 2012, compared to 36% for the same period last year. This decrease is mainly due to a weaker pricing environment and an effort to maintain full capacity utilization.

- 19 -

	2012		2011
Operating expenses	$	28,206	$	29,116

Operating expenses for the three months ended March 31, 2012 decreased approximately $1 million compared to the same period last year. Of the components within operating expenses, selling, general and administrative expenses (“SG&A”) increased less than $1 million, and research and development expenses (“R&D”) also increased less than $1 million. In addition, included in operating expenses for 2012 is a gain of approximately $2 million on the sale of intangible assets. SG&A, as a percentage of sales, increased to 15% for the three months ended March 31, 2012, compared to 13% in the same period last year, and R&D, as a percentage of sales, increased to 5% for the three months ended March 31, 2012, compared to 4% in the same period last year, mainly due to the decrease in net sales.

	2012		2011
Other income (expenses)	$	687	$	(3,178	)

Other income for the three months ended March 31, 2012 was approximately $1 million, compared to other expenses of approximately $3 million in the same period last year. For the three months ended March 31, 2011, other expense included approximately $2 million for the amortization of debt discount related to our convertible senior notes, which were repurchased in 2011.

	2012		2011
Income tax provision	$	618	$	4,835

We recognized income tax expense of approximately $1 million for the three months ended March 31, 2012, compared to approximately $5 million income tax expense in the same period last year. The estimated effective tax rate is 10% for the three months ended March 31, 2012, compared to 19% in the same period last year. Our effective tax rates for the three months ended March 31, 2012 and 2011, respectively, were lower than the U.S. statutory tax rate of 35%, principally from the impact of higher income in lower-taxed jurisdictions.

Financial Condition

Liquidity and Capital Resources

Our primary sources of liquidity are cash and cash equivalents, funds from operations and, if necessary, borrowings under our credit facilities. We currently have a U.S. credit agreement for a $10 million revolving credit facility and a $10 million uncommitted facility with $10 million outstanding borrowings. Our U.S. credit agreement’s maturity date is January 17, 2013. In addition, we have foreign credit facilities with borrowing capacities of approximately $48 million with $1 million outstanding borrowings and $1 million used for import and export guarantees. Our primary liquidity requirements have been to meet our inventory and capital expenditure needs and to fund on-going operations. At December 31, 2011 and March 31, 2012, our working capital was $317 million and $368 million, respectively. Our working capital increased in the first three months of 2012 primarily due to the increase in cash and cash equivalents, mainly due to a draw down on our $40 million term loan. We expect cash generated by our operations, together with existing cash, cash equivalents and available credit facilities, to be sufficient to cover cash needs for working capital and capital expenditures for at least the next 12 months.

Capital expenditures for the three months ended March 31, 2012 and 2011 were $16 million and $19 million, respectively, which includes $8 million and $1 million, respectively, of capital expenditures related to the investment agreement with the Management Committee of the CDHT. Capital expenditures, excluding capital expenditures related to the investment agreement, in the first three months of 2012 were approximately 5% of our net sales and were primarily related to manufacturing expansion in our facilities in China.

Discussion of Cash Flow

Cash and cash equivalents increased from $130 million at December 31, 2011 to $177 million at March 31, 2012 primarily from cash provided by operating and financing activities, offset in part by cash used by investing activities.

A summary of the consolidated condensed statements of cash flows is as follows (in thousands):

	Three Months Ended March 31,
	2012			2011			Change
Net cash provided by operating activities	$	13,447		$	15,730		$	(2,283	)
Net cash used by investing activities		(9,667	)		(13,060	)		3,393
Net cash provided by financing activities		42,760			2,480			40,280
Effect of exchange rates on cash and cash equivalents		678			2,689			(2,011	)
Net increase in cash and cash equivalents	$	47,218		$	7,839		$	39,379

Operating Activities

Net cash provided by operating activities for the three months ended March 31, 2012 was $13 million, resulting primarily from $6 million of net income, $16 million in depreciation and amortization and a decrease in inventories, offset partially by an increase in accounts receivable. Net cash provided by operating activities was $16 million for the same period last year, resulting primarily from $20 million of net income and $14 million in depreciation and amortization, offset partially by a $16 million increase in accounts receivable.

Investing Activities

Net cash used by investing activities was $10 million for the three months ended March 31, 2012 compared to net cash used by investing activities of $13 million for the same period last year. While cash used for purchases of property, plant and equipment was approximately $12 million for both the three months ended March 31, 2012 and 2011, included in the three months ended March 31, 2012 was approximately $2 million in proceeds from the sale of intangibles.

- 21 -

Financing Activities

Net cash provided by financing activities was $43 million for the three months ended March 31, 2012 compared to net cash provided by financing activities of $3 million in the same period last year. This increase in net cash provided by financing activities was due primarily to a $40 million draw down on our term loan.

Debt Instruments

There have been no material changes to our debt instruments as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011, filed on February 28, 2012.

Off-Balance Sheet Arrangements

We do not have any transactions, arrangements and other relationships with unconsolidated entities that will affect our liquidity or capital resources. We have no special purpose entities that provide off-balance sheet financing, liquidity or market or credit risk support, nor do we engage in leasing, swap agreements, or outsourcing of research and development services, that could expose us to liability that is not reflected on the face of our financial statements.

Contractual Obligations

There have been no material changes in any of our contractual obligations as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011, filed on February 28, 2012, except for an additional term loan in the amount of $40 million that we drew down in full on February 1, 2012 and matures on January 17, 2015.

Critical Accounting Policies

Our critical accounting policies, as described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011, relate to revenue recognition, inventories, accounting for income taxes, goodwill and long-lived assets, share-based compensation, fair value measurements, defined benefit plan and contingencies. There have been no material changes to our critical accounting policies as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011, filed on February 28, 2012.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

Our Chief Executive Officer, Keh-Shew Lu, and Chief Financial Officer, Richard D. White, with the participation of the Company’s management, carried out an evaluation of the effectiveness of our disclosure controls and procedures pursuant to Exchange Act Rule 13a-15(e). Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer believe that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures are effective at the reasonable assurance level to ensure that information required to be included in this report is:

• recorded, processed, summarized and reported within the time period specified in the Commission’s rules and forms; and

• accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely decisions required disclosure.

Disclosure controls and procedures, no matter how well designed and implemented, can provide only reasonable assurance of achieving an entity’s disclosure objectives. The likelihood of achieving such objectives is affected by limitations inherent in disclosure controls and procedures. These include the fact that human judgment in decision-making can be faulty and that breakdowns in internal control can occur because of human failures such as simple errors, mistakes or intentional circumvention of the established processes.

Changes in Controls over Financial Reporting

There was no change in our internal control over financial reporting, known to our Chief Executive Officer or our Chief Financial Officer, that occurred during the fiscal quarter covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
