NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 - Basis of Presentation:

The accompanying consolidated financial statements are unaudited and have been prepared by Lattice Semiconductor Corporation (“the Company”) pursuant to the rules and regulations of the Securities and Exchange Commission and in our opinion include all adjustments, consisting only of normal recurring adjustments, necessary for the fair statement of results for the interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. These consolidated financial statements should be read in conjunction with our audited financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 2002.

On August 26, 2002, we completed the stock for stock acquisition of Cerdelinx Technologies, Inc. (“Cerdelinx”) for 2.6 million shares valued at $8.30 per share. This transaction was accounted for as an asset purchase, and accordingly, the results of operations for Cerdelinx and estimated fair value of assets acquired and liabilities assumed were included in our condensed consolidated financial statements beginning August 26, 2002. This acquisition is discussed further in Note 4.

On January 18, 2002, we completed the acquisition of the field-programmable gate array (“FPGA”) business (“Agere FPGA”) of Agere Systems Inc. (“Agere”) for $250 million in cash. This transaction was accounted for as an asset purchase, and accordingly, the results of operations for Agere FPGA and estimated fair value of assets acquired and liabilities assumed were included in our condensed consolidated financial statements beginning January 18, 2002. This acquisition is discussed further in Note 5.

The preparation of financial statements in conformity with generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the fiscal periods presented. Actual results could differ from these estimates.

We report based on a 52 or 53 week year ending on the Saturday closest to December 31. For ease of presentation, we have adopted the convention of using March 31, June 30, September 30 and December 31 as period end dates for all financial statement captions.

This Quarterly Report on Form 10-Q contains forward looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended. Actual results could differ materially from those projected in the forward-looking statements as a result of the factors, set forth in the section entitled “Factors Affecting Future Results” and elsewhere in this report.

Note 2 - Revenue Recognition:

Revenue from sales to OEM customers is recognized upon shipment provided that persuasive evidence of an arrangement exists, the price is fixed, title has transferred, collection of resulting receivables is probable, there are no customer acceptance requirements and no remaining significant obligations. Certain of our sales are made to distributors under agreements providing price protection and right of return on unsold merchandise. Revenue and cost relating to such distributor sales are deferred until the product is sold by the distributor and related revenue and costs are then reflected in income. Revenue from software sales was not material for the periods presented.

Note 3 – Net Income Per Share:

Net income per share is computed based on the weighted average number of shares of common stock and potentially dilutive securities assumed to be outstanding during the period using the treasury stock method. Potentially dilutive securities consist of stock options, warrants to purchase common stock and convertible subordinated notes.

The most significant difference between the computation of basic and diluted net income per share is that basic net income per share does not treat potentially dilutive securities such as stock options, warrants and convertible subordinated notes as outstanding. For all periods presented, the computation of net loss per share excludes the effect of our stock options, warrants and convertible notes as they were antidilutive. A reconciliation of basic and diluted net income per share is presented below (in thousands, except for per share data):

	Three months ended						Six months ended

Stock-Based Compensation

We account for our employee and director stock options and employee stock purchase plan in accordance with provisions of Accounting Principles Board Opinion No. 25 (“APB 25”), “Accounting for Stock Issued to Employees.” Pro forma disclosures as required under Statement of Financial Accounting Standards (“SFAS”) 123, “Accounting for Stock-Based Compensation” and as amended by SFAS 148, “Accounting for Stock-Based Compensation – Transition and Disclosure,” are presented below. Pursuant to FASB Interpretation No. 44 “Accounting for Certain Transactions Involving Stock Based Compensation – an interpretation of APB Opinion No. 25,” effective July 1, 2000, the “in the money” portion of stock options granted to employees in connection with acquisitions is accounted for as Deferred Stock Compensation in Stockholders’ Equity and amortized to operations as part of Amortization of Intangible Assets over the vesting periods of the options.

The fair value of our stock-based employee compensation cost for purposes of our pro forma disclosures was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:

	Grants for
	Three months ended				Six months ended
	June 30, 2003		June 30, 2002		June 30, 2003		June 30, 2002
Stock Options:
Expected Volatility	57.1	%	59.3	%	58.1	%	59.3	%
Risk-free interest rate	1.9	%	3.7	%	2.1	%	3.6	%
Expected life from vesting date	1.6 years		1.8 years		0.5 years		1.8 years
Dividend yield	0	%	0	%	0	%	0	%

The Black-Scholes option pricing model was developed for use in estimating the fair value of freely tradable, fully transferable options without vesting restrictions. Our stock options have characteristics which differ significantly from those of freely tradable, fully transferable options. The Black-Scholes option pricing model also requires highly subjective assumptions, including expected stock price volatility and expected stock option term which greatly affect the calculated fair value of an option. Our actual stock price volatility and option term may be materially different from the assumptions used herein.

As pertaining to activity for the three and six months ended June 30, 2003 and 2002, the resultant grant date weighted-average fair values calculated using the Black-Scholes option pricing model and the noted assumptions for stock options granted were $3.97 and $5.15 for the second quarter of 2003 and 2002, respectively, and $1.25 and $6.93 for the six months ended June 30, 2003 and 2002, respectively. For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the options’ vesting period.

Our pro forma information is as follows (in thousands, except per share data):

	Three months ended June 30, 2003			Three months ended June 30, 2002			Six months ended June 30, 2003			Six months ended June 30, 2002

Note 4 — Acquisition of Cerdelinx:

On August 26, 2002, we completed the stock for stock acquisition of Cerdelinx for 2.6 million shares valued at $8.30 per share. Cerdelinx was an early stage fabless semiconductor company focused on the design of application specific standard products targeted towards emerging high-speed communications and storage applications. Cerdelinx had a team of engineers who were developing a portfolio of low-power CMOS transceivers and backplane interfaces with embedded high-speed SERDES I/O to support 10 gigabit-per-second applications. The acquisition serves to enhance our silicon development efforts and our ability to deliver leading-edge programmable solutions within the communications and storage market segments. This acquisition principally comprises intellectual property and a work force. The core technology portion of the intellectual property is valued using a royalty savings methodology which discounts estimated royalties that would be paid on an after tax basis. The in-process technology portion of the intellectual property is valued using a discounted cash flow methodology described in detail below. Work force is valued using a replacement cost methodology which discounts costs to an after tax amount. The transaction was completed pursuant to an Agreement and Plan of Reorganization entered into on July 15, 2002, as amended on July 24, 2002, among Lattice, Cerdelinx and affiliated parties. The components of the purchase price were as follows (in millions):

Stock issued and liabilities assumed	$	22.8

Estimated direct acquisition costs	1.1
Total	$	23.9

In conformity with Financial Accounting Standard SFAS 142, “Goodwill and Other Intangible Assets”, the total purchase price was allocated to the estimated fair value of assets acquired and liabilities assumed. As Cerdelinx was not considered a business under SFAS 141, “Business Combinations,” no goodwill was recognized. In estimating the fair value of the assets acquired, management considered various factors, including an appraisal. The purchase price allocation is subject to further refinement and change over the four quarters subsequent to the acquisition. We are in the process of completing our integration of Cerdelinx and accordingly, the amounts recorded are based on our current estimates of these costs. The total purchase price was allocated as follows (in millions):

Core technology	$	7.2
Deferred stock compensation	5.8
In process research and development costs	5.7
Work force	4.7
Liabilities assumed	(1.2		)
Equipment	1.1
Non compete agreement	0.3
Cash	0.3

Total	$	23.9

There were no significant exit costs incurred or accrued in connection with this transaction. Management does not expect intangible assets acquired to be deductible for income tax purposes.

Employees who joined Lattice as a result of this acquisition held Cerdelinx shares and options which were converted into 0.9 million Lattice shares and options which were either unvested or otherwise restricted from sale over terms up to four years at a grant price from $0.41 per share to $2.54 per share. The spread, which is the difference between grant price and market value of our common stock on the Closing Date, aggregating $5.8 million on these shares and options, was recorded as Paid-in capital and Deferred stock compensation and is being amortized to operations equally over the vesting (or restriction lapsing) period as part of Amortization of intangible assets.

In-Process Research and Development (“IPR&D”)

IPR&D consists of those products obtained through acquisition that are not yet proven to be technologically feasible but have been developed to a point where there is value associated with them in relation to potential future revenue. Because technological feasibility was not yet proven and no alternative future uses are believed to exist for the in-process technologies, the assigned value was expensed immediately after the closing of the acquisition.

The fair value underlying the $5.7 million assigned to acquired IPR&D from the Cerdelinx acquisition (recognized in the third quarter of 2002) was determined by identifying research projects in areas for which technological feasibility had not been established and there were no alternative future uses. The acquired IPR&D consists of low-power CMOS transceivers and backplane interfaces with embedded high-speed SERDES I/O. These products were approximately 60%

complete and are estimated to be completed in 2003 at an estimated cost of approximately $2 million. There has been no material change in the schedule or estimated cost of this project.

The fair value was determined by an income approach where fair value is the present value of projected free cash flows that will be generated by the products incorporating the acquired technologies under development, assuming they are successfully completed. The estimated net free cash flows generated by the products over six year periods were discounted at rates ranging from 15 to 17 percent in relation to the stage of completion and the technical risks associated with achieving technological feasibility. The net cash flows for such projects were based on management’s estimates of revenue, expenses and asset requirements.

All of these projects have completion risks related to silicon functionality, architecture performance, process technology availability, packaging technology, continued availability of key technical personnel and product reliability. To the extent that estimated completion dates are not met, the risk of competitive product introduction is greater and revenue opportunity may be permanently lost.

The core technology included in the acquisition of Cerdelinx has an estimated weighted average useful life of approximately six years, and the work force and non-compete agreements included in the Cerdelinx acquisition have estimated useful lives of approximately four years resulting in a weighted average useful life of approximately five years.

Note 5 – Acquisition of Agere FPGA:

On January 18, 2002, we completed the acquisition of Agere FPGA for $250 million in cash. This acquisition increased our share of the PLD market, accelerated our entry into the FPGA portion of the market and provided us with additional technical employees and intellectual property. This acquisition principally comprises intellectual property, which was valued using a discounted cash flow methodology of which goodwill was a by-product. The transaction was completed pursuant to an Asset Purchase Agreement dated as of December 7, 2001 between Lattice and Agere. The components of the purchase price were as follows (in millions):

*Cash*	$	250.0
*Estimated direct acquisition costs*	*6.3*
*Total*	$	*256.3*

In accordance with SFAS 141, the total purchase price was allocated to the estimated fair value of assets acquired and liabilities assumed. In estimating the fair value of the assets acquired, management considered various factors, including an appraisal. The total purchase price was allocated as follows (in millions):

*Excess of purchase price over net assets acquired*	$	*142.4*
*Current technology*	*63.4*
*In-process research and development*	*24.2*
*Fair value of non-compete agreement*	*13.8*
*Licensed technology*	*10.2*
*Inventory*	*3.5*
*Backlog*	*1.4*
*Property, plant and equipment*	*0.2*
*Accrued liabilities*	*(2.8*		)

*Total*	$	*256.3*

There were no significant exit costs incurred or accrued in connection with this transaction.

Employees joining us from Agere during the first quarter of 2002 were awarded approximately 1.1 million stock options which vest equally over four years at a grant price of $14.76 per share. The difference between grant price and market value of our common stock on the grant date, aggregating approximately $7.0 million, was recorded as Paid-in capital and Deferred stock compensation and is being amortized to operations ratably over the vesting period as part of Amortization of intangible assets.

In-Process Research and Development (“IPR&D”)

The fair value underlying the $24.2 million assigned to acquired IPR&D in the Agere FPGA acquisition was determined by identifying research projects in areas for which technological feasibility had not been established and there was no alternative future use. Projects in the IPR&D category are the ORCA 4 FPGA family, the next generation FPGA family and the FPSC field-programmable system chips. The following is a brief description of these projects. The ORCA 4 FPGA family project, increasing speed and density and enhancing yields, was approximately 85% complete and estimated to be completed by 2003 at an estimated cost of $1.5 million. This project was completed during 2002 with no material change in cost. The next generation FPGA family project, increasing speed and density while reducing die size, was approximately 50% complete and estimated to be completed by 2004 at an estimated cost of $2 million. There has been no material change in the schedule or estimated cost of this project. The future development of FPSC field-programmable system chips (field-programmable system chips which combine embedded pre-defined logic circuits

with an FPGA platform) was approximately 25% to 90% complete, and estimated to be completed by 2004 at an estimated cost of $2 million. There has been no material change in the schedule or estimated cost of this project. The IPR&D value of $24.2 million was determined by an income approach where fair value is the present value of projected free cash flows that will be generated by the products incorporating the acquired technologies under development, assuming they are successfully completed. The estimated net free cash flows generated by the products over 5-7 year periods were discounted at rates ranging from 23 to 25 percent in relation to the stage of completion and the technical risks associated with achieving technological feasibility. The net cash flows for such projects were based on management’s estimates of revenue, expenses and asset requirements. Any delays or failures in the completion of these projects could impact our expected return on investment and future results. In addition, our financial condition would be adversely affected if the value of other intangible assets acquired became impaired.

All of these projects have completion risks related to silicon functionality, architecture performance, process technology availability, packaging technology, continued availability of key technical personnel, product reliability and availability of software support. To the extent that estimated completion dates are not met, the risk of competitors’ product introductions is greater and revenue opportunity may be permanently lost.

The non-compete agreement from Agere and the current and licensed technology included in the acquisition of Agere FPGA have an estimated weighted average useful life of approximately 6.3 years. In accordance with SFAS 142, the excess of purchase price over net assets acquired, or Goodwill, is subject to an impairment test at least annually and is not amortized.

Note 6 - Acquisition of Vantis:

On June 15, 1999, we paid approximately $500.1 million in cash to AMD for all of the outstanding capital stock of Vantis Corporation. The total purchase price of Vantis was $583.1 million, including certain direct acquisition costs, the accrual of certain exit costs and the assumption of certain liabilities related to the Vantis business. Of this purchase price, approximately $422.6 million was allocated to goodwill and intangible assets.

The recorded balances of goodwill and intangible assets, net of accumulated amortization, related to the Vantis acquisition approximated $77.1 million and $48.7 million, respectively, at June 30, 2003 and $77.1 million and $74.2 million, respectively, at December 31, 2002. Amortization expense related to intangible assets approximated $25.5 million for both the first six months of 2003 and the first six months of 2002.

Note 9 - New Accounting Pronouncements:

In June 2001, the FASB issued SFAS 142, which supersedes APB Opinion No. 17, “Intangible Assets.” SFAS 142, among other things, establishes new standards for intangible assets acquired in a business combination, eliminates amortization of goodwill and sets forth requirements to periodically evaluate goodwill for impairment. We adopted this statement during the first quarter of 2002 and thus goodwill and certain intangibles with indefinite lives are no longer being amortized. To apply SFAS 142, a company is divided into separate “reporting units,” each representing groups of products that are separately managed. For this purpose, we have one reporting unit. To determine whether or not goodwill may be impaired, a test is required comparing the book value of the “reporting unit” to its trading price. Similar tests are required in the future, at least annually, and more often where there is a change in circumstances that could result in an impairment of goodwill. If the trading price of our common stock is below the book value for a sustained period, a goodwill impairment test will be performed by comparing book value to estimated market value (trading price plus a control premium). The excess of book value over estimated market value will then be subtracted from the goodwill account with a resulting charge to operations. Subsequent unrealized recoveries in market value, if any, will not be recorded. We completed an initial goodwill impairment assessment as of January 1, 2002 to determine if a transition impairment charge should be recognized under SFAS 142. Upon assessment, no transition impairment charge was recorded. We also completed our annual goodwill impairment assessment in December 2002, upon which no impairment charge was recorded. Additional goodwill impairment tests will be performed at least annually.

The following tables present details of the Company’s total purchased intangible assets (in millions):

Total	$	355.6	$	(199.6	)	$	156.0

The estimated future amortization expense of purchased intangible assets as of June 30, 2003 is as follows (in millions):

Fiscal Year:	Amount

2003 (remaining six months)	$	35.7
2004	43.8
2005	14.4
2006	10.8
2007	9.8
Later years	5.8
	$	120.3

The estimated future amortization expense of deferred stock compensation attributable to Research and Development activities as of June 30, 2003 is approximately $1.5 million for the remainder of 2003, $3.3 million for 2004, and $2.3 million for 2005.

In May 2002, the FASB issued SFAS 145, “Rescission of FAS Nos. 4, 44, and 64, Amendment of FAS 13, and Technical Corrections.” Among other things, SFAS 145 rescinds various pronouncements regarding early extinguishment of debt and allows extraordinary accounting treatment for early extinguishment only when the provisions of Accounting Principles Board Opinion No. 30, “Reporting the Results of Operations – Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions” are met. SFAS 145 provisions regarding early extinguishment of debt are generally effective for fiscal years beginning after May 15, 2002. Management adopted this pronouncement during the second quarter of 2002. During the second through fourth quarters of 2002, we extinguished approximately $51.9 million face value of our 4¾% convertible notes for approximately $42.8 million in cash, including accrued interest. We recognized a gain of approximately $9.3 million in connection with these transactions. During the first quarter of 2003, we extinguished approximately $32.8 million of these notes for approximately $29.9 million in cash including accrued interest and recognized a gain of approximately $2.9 million. During the second

quarter of 2003, we extinguished $3.0 million of these notes for approximately the same amount in cash including accrued interest, at approximately carrying cost. As specified in SFAS 145, gains recognized were recorded in “Other (expense) income, net” in the accompanying Consolidated Statement of Operations.

In December 2002, the FASB issued SFAS 148, “Accounting for Stock-Based Compensation – Transition and Disclosure.” This statement provides alternative methods of transition for a voluntary change to the fair value method of accounting for stock-based employee compensation. In addition, it amends the disclosure requirements of SFAS 123 to require prominent disclosure in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reporting results. This statement is effective for fiscal years ending after December 15, 2002 and for the interim periods beginning after December 15, 2002. As we continue to report stock-based employee compensation costs using the intrinsic value method as defined by APB 25, adoption of the provisions of the new statement affects only our disclosure of these costs, which is presented in Note 3.

Note 10 - Legal Matters:

We are not currently a party to any material legal proceedings. We are exposed to certain asserted and unasserted potential claims. There can be no assurance with respect to potential claims made against us, that we could resolve such claims under terms and conditions that would not have a material adverse effect on our financial position, cash flows or results of operations.

Note 11 – Foundry Investment:

In 1995, we entered into a series of agreements with United Microelectronics Corporation (“UMC”), a public Taiwanese company, pursuant to which we agreed to join UMC and several other companies to form a separate Taiwanese corporation, (“UICC”), for the purpose of building and operating an advanced semiconductor manufacturing facility in Taiwan, Republic of China. Under the terms of the agreements, we invested approximately $49.7 million for an approximate 10% equity interest in the corporation and the right to receive a percentage of the facility’s wafer production at market prices.

In 1996, we entered into an agreement with Utek Corporation (“Utek”), a public Taiwanese company in the wafer foundry business that became affiliated with the UMC group in 1998, pursuant to which we agreed to make a series of equity investments in Utek under specific terms. In exchange for these investments, we received the right to purchase a percentage of Utek’s wafer production. Under this agreement, we invested approximately $17.5 million. On January 3, 2000, UICC and Utek merged into UMC.

During 2002, we sold approximately 7.6 million of our UMC shares for approximately $9.9 million, resulting in a gain of $4.0 million. In the future, we may or may not choose to liquidate additional UMC shares. As of June 30, 2003, we owned approximately 88.2 million shares of UMC common stock of which approximately 23.3 million are restricted from sale for more than one year by the terms of our agreement with UMC. Under the terms of the UMC agreement, if we sell any of these restricted shares, our rights to guaranteed wafer capacity at UMC may be reduced on a pro-rata basis based on the number of shares that we sell. If we sell over 10.1 million of these restricted shares, we may lose all of our rights to guaranteed wafer capacity at UMC.

For financial reporting purposes, all of our UMC shares are accounted for as available for sale and marked to market in our Consolidated Balance Sheet until they are sold, at which time a gain or loss is recognized in our Consolidated Statement of Operations. Unrealized gains and losses are included in Accumulated other comprehensive (loss) income within Stockholders’ Equity. An other than temporary impairment of UMC share value could result in a reduction of the Consolidated Balance Sheet carrying value and would result in a charge to our Consolidated Statement of Operations.

The carrying value of our investment in UMC was approximately $57.7 million and $56.3 million at June 30, 2003 and December 31, 2002, respectively, and this balance is classified as part of Foundry investments, advances and other assets. During the first quarter of 2003, we recorded a $5.0 million unrealized loss related to changes in the market value of our unrestricted UMC shares. During the second quarter of 2003, we recorded a $6.4 million unrealized gain related to the change in market value of these shares. If we liquidate our UMC shares, it is likely that the amount of any future realized gain or loss will be different from the accounting gain or loss reported in prior periods.

Note 12 – Segment and Geographic Information:

We operate in one industry segment comprising the design, development, manufacture and marketing of high performance programmable logic devices. Our sales by major geographic area were as follows (in thousands):

	Three Months Ended				Six Months Ended
	June 30, 2003		June 30, 2002		June 30, 2003		June 30, 2002

United States	$	23,929	$	23,995	$	42,880	$	48,711
Export sales:
Europe	14,221		13,239		31,113		30,447
Asia	17,938		16,807		35,271		30,114

	$	58,178	$	56,466	$	116,489	$	115,344

Resale of product through two distributors accounted for approximately 22% and 19% of revenue in the first six months of 2003, and 24% and 18%, respectively, for the first six months of 2002. More than 90% of our property and equipment is located in the United States. Other long-lived assets located outside the United States consist primarily of foundry investments and advances.

Note 13 - Stock Option Exchange Program:

On March 14, 2003, we completed a stock option exchange program. Under the exchange offer, eligible employees had the opportunity to tender for cancellation certain stock options in exchange for new options to be granted at least six months and one day after the cancellation of the tendered options. Each eligible participant will receive four new options to purchase shares of common stock for every seven options submitted for cancellation. We accepted approximately 11.2 million options for exchange and currently expect to grant approximately 6.4 million new options, subject to adjustment for employee terminations since the cancellation date. The exercise price per share of the

new options will be equal to the fair market value of our common stock on the new grant date, which is expected to be September 18, 2003.

In connection with the stock option exchange program, we accelerated the write-off of accrued deferred compensation recorded in conjunction with certain of our acquisitions, due to the cancellation of certain assumed in–the-money stock options. Such acceleration resulted in $2.2 million of additional intangible asset amortization expense in the first quarter of 2003. However, we do not expect to record any additional compensation expense as a result of the exchange program.

Note 14- Convertible Subordinated Notes:

On June 20, 2003, we issued $200 million in Zero Coupon convertible subordinated notes due on July 1, 2010. No interest will accrue or be payable related to these notes. Holders of these notes may convert the notes into shares of our common stock at any time before the close of business on the date of their maturity, unless the notes have been previously redeemed or repurchased, if (1) the price of our common stock issuable upon conversion of a note reaches a specified threshold, (2) the notes are called for redemption, (3) specified corporate transactions occur or (4) the trading price of the notes falls below certain thresholds. The conversion price is approximately $12.06 per share, subject to adjustment in certain circumstances. On or after July 1, 2008, we have the option to redeem all or a portion of the notes that have not been previously repurchased or converted at 100% of the principal amount of the notes. On July 1, 2008, holders have the option to require us to purchase all or a portion of their notes in cash at 100% of the principal amount of the notes. The notes are subordinated in right of payment to all of our senior indebtedness, and are subordinated by operation of law to all liabilities of our subsidiaries. At June 30, 2003, we had no senior indebtedness and our subsidiaries had approximately $2.3 million of debt and other liabilities outstanding. Issuance costs relative to these convertible notes are included in “Foundry investments, advances and other assets” and aggregated approximately $5.5 million and are being amortized to expense over the lives of the notes. Accumulated amortization of these issuance costs was not significant as of June 30, 2003.

On July 21, 2003, we redeemed for cash all of our outstanding 4¾% convertible subordinated notes due in 2006 plus accrued interest. Total cash paid at redemption approximated $178.8 million, including par value of $172.3 million, accrued interest of approximately $1.8 million and a call premium of 2.71% of the outstanding notes, or approximately $4.7 million. This call premium, plus unamortized issuance costs of approximately $1.0 million as of the redemption date, will be recorded as “Other expense” in the quarter ended September 30, 2003.

Our end customers are primarily original equipment manufacturers in the communications, computing, industrial, automotive, medical, consumer and military end markets.

Results of Operations

Key elements of our consolidated statement of operations, expressed as a percentage of revenues, were as follows:

	Three Months Ended				Six Months Ended
	June 30, 2003		June 30, 2002		June 30, 2003		June 30, 2002

Loss from operations	(31.1	)%	(30.5	)%	(33.0	)%	(50.3	)%

Revenue:

Revenue for the second quarter of 2003 increased by $1.7 million, or three percent, as compared to the second quarter of 2002, and by $1.1 million, or one percent for the first six months of 2003 when compared to the first six months of 2002. The composition of our revenue by product family for the second quarter and first six months of 2003 and 2002, respectively, was as follows:

	Three Months Ended				Six Months Ended
	June 30, 2003		June 30, 2002		June 30, 2003		June 30, 2002
FPGA	16	%	13	%	15	%	10	%
CPLD	69	%	68	%	70	%	70	%
SPLD	15	%	19	%	15	%	20	%

We acquired Agere FPGA on January 18, 2002 (see Note 5). Prior to the acquisition, we had no revenue from the sale of FPGA products.

Beginning in 2001, the semiconductor and PLD markets experienced a significant downturn, which has continued into 2003. The slight revenue increase in the second quarter and first six months of 2003 as compared to the second quarter and first six months of 2002 was primarily due to revenue from the sale of new products. Nonetheless, overall revenue levels for all periods presented remain substantially depressed from earlier periods and reflect the continued downturn and resultant overall decrease in demand for our products. On July 21, 2003, we announced that we expected revenues for the quarter ended September 30, 2003 to be between $52 million and $55 million.

As a percentage of total revenue, U.S. sales declined to 37% for the first six months of 2003 as compared to 42% for the first six months of 2002. Export sales to Asia rose as a percentage of total revenue, from 26% in the first six months of 2002 to 30% in the first six months of 2003. Export sales to Europe were approximately flat when comparing both fiscal periods, both in absolute and percentage terms.

During the second quarter of 2003, units sold and average selling prices were both slightly higher as compared to the second quarter of 2002. The increase in the 2003 quarter was due primarily to product mix. During the first six months of 2003, total units sold increased by four percent and average selling price decreased by three percent when compared to the first six months of 2002. The decrease in average selling price was primarily due to price declines associated with the downturn in the semiconductor and PLD markets. Although selling prices of mature products generally decline over time, this decline is at times offset by higher selling prices of new products. Our ability to achieve revenue growth is in large part dependent on the continued development, introduction and market acceptance of new products. See “Factors Affecting Future Results.”

Gross margin:

Gross margin as a percentage of revenue was approximately flat for all periods presented. Reductions in overall manufacturing costs were essentially offset by changes in production volume and product mix. Reductions in overall manufacturing costs resulted primarily from on-going yield improvements, migration of products to more advanced technologies and reductions in wafer and assembly costs.

Research and development:

Research and development expenses increased by $0.6 million and $1.1 million, respectively, in the second quarter and first six months of 2003 when compared to the same calendar periods in 2002. Research and development expenses consist primarily of labor, masks, prototype wafers, third-party design automation software, assembly tooling and qualification expenses. The increase in research and development expense was primarily due to increased headcount and related spending due to our acquisition of Cerdelinx (see Note 4). We believe that a continued commitment to research and development is essential in order to maintain product leadership of our existing product families and to provide innovative new product offerings, and therefore we expect to continue to make significant future investments in research and development.

Selling, General and Administrative Expense:

Selling, general and administrative (“SG&A”) expenses increased approximately $0.4 million and $1.0 million, respectively, in the second quarter and first six months of 2003 when compared to the same calendar periods of 2002. These increases were primarily due to increased selling and marketing expenses related to new products.

In-Process Research and Development:

Agere FPGA

completed. The estimated net free cash flows generated by the products over 5-7 year periods were discounted at rates ranging from 23 to 25 percent in relation to the stage of completion and the technical risks associated with achieving technological feasibility. The net cash flows for such projects were based on management’s estimates of revenue, expenses and asset requirements. Any delays or failures in the completion of these projects could impact our expected return on investment and future results. In addition, our financial condition would be adversely affected if the value of other intangible assets acquired became impaired.

All of these projects have completion risks related to silicon functionality, architecture performance, process technology availability, packaging technology, continued availability of key technical personnel, product reliability and availability of software support. To the extent that estimated completion dates are not met, the risk of competitors’ product introductions is greater and revenue opportunity may be permanently lost.

Amortization of Intangible Assets:

Amortization of intangible assets is related to our 2002 acquisitions of Agere FPGA and Cerdelinx, our 1999 Vantis acquisition and our 2001 acquisition of Integrated Intellectual Property, Inc. (“I2P”). Amortization expense was $18.7 million and $39.8 million in the second quarter and first six months of 2003, an increase of $0.8 million and $3.3 million when compared to the same calendar periods of 2002. The most significant portion ($2.2 million) of this increase resulted from the accelerated write-off of accrued deferred compensation recorded in the first quarter of 2003 in conjunction with certain of our acquisitions, due to the cancellation of certain assumed in-the-money stock options as part of a stock option exchange program initiated during the first quarter of 2003 (see Note 13). Nearly all of the remaining increase resulted from the amortization of intangible assets related to our acquisition of Cerdelinx.

Other (expense) income, net:

Other (expense) income, net, was $(1.4 million) and $0.1 million, respectively, in the second quarter and first six months of 2003, as compared to $3.1 million and $1.2 million, respectively, for the same calendar periods of 2002. During the second quarter of 2002, we recorded a $4.0 million gain in connection with the sale of approximately 7.6 million unrestricted UMC shares (see Note 11). There was no such transaction in the 2003 periods. Additionally during the second quarter of 2002, we recorded a $1.2 million gain in connection with the extinguishment of a portion of our 4 3/4% convertible notes. During the first quarter of 2003, we recorded a gain of approximately $2.9 million in connection with the extinguishment of an additional portion of these convertible notes. In conjunction with reducing our outstanding 4 ¾% convertible debt from $260 million at the end of the first quarter of 2002 to approximately $172 million at the end of the second quarter of 2003, quarterly interest expense was reduced from $3.1 million to $2.2 million, a reduction of approximately $0.9 million per quarter.

Additional reductions in other income resulted from a reduction in interest income on invested balances caused by lower interest rates and a decrease in invested balances.

Benefit for income taxes:

During the second quarter of 2003, we recorded an income tax benefit of approximately $2.6 million, related to a refund of federal income taxes of approximately $28.1 million received in the second quarter of 2003 and resulting from the carryback of 2002 net operating losses to prior profitable periods.

The benefit for income taxes was $6.0 million and $23.1 million, respectively, in the second quarter and first six months of 2002. No income taxes were provided for in the first quarter of 2003. This is the result of the following factors:

1) We continued to experience significant losses during the first quarter of 2003 and are currently not paying any significant income taxes;

2) Federal net operating loss carrybacks and credit carrybacks available in prior periods are no longer available; and,

3) In the fourth quarter of 2002, we recorded a $118.6 million charge to income tax expense, representing a valuation allowance on our recorded deferred tax assets, in accordance with SFAS 109, “Accounting for Income Taxes.” We provided a valuation allowance equal to our net deferred tax assets due to uncertainties regarding their realization. Due to continued uncertainties regarding their realization, we continue to provide a valuation allowance equal to our net deferred tax assets.

FACTORS AFFECTING FUTURE RESULTS

A continuing downturn in the communications equipment and computing end markets has caused a reduction in demand for our products and limited our ability to maintain or increase revenue levels and operating results.

A significant portion of our revenue is derived from customers in the communications equipment and computing end markets. A downturn in the economy could lead to a contraction of capital spending on information technology. This in turn could lead to a reduction in the demand for communications or computing equipment and for our products.

Due to a deterioration in overall economic conditions and a significant reduction in information technology capital spending, the communications and computing end markets are currently experiencing significant and prolonged downturns. At present and in the future when these or other similar conditions exist, there is likely to be an adverse effect on our operating results.

The cyclical nature of the semiconductor industry may limit our ability to maintain or increase revenue levels and operating results during current or future industry downturns.

The semiconductor industry is highly cyclical, to a greater extent than other less technology-driven industries. Our financial performance has periodically been negatively affected by downturns in the semiconductor industry. Factors that contribute to these industry downturns include:

• the cyclical nature of the demand for the products of semiconductor customers;

• general reductions in inventory levels by customers;

• excess production capacity;

• general decline in end-user demand; and

• accelerated declines in average selling prices.

Beginning in 2001, the semiconductor industry experienced a significant downturn. At present and in the future when these or other similar conditions exist, there is likely to be an adverse effect on our operating results.

We may experience unexpected difficulties integrating the field programmable gate array, or FPGA, business which we recently purchased from Agere.

On January 18, 2002, we acquired the FPGA business of Agere Systems and are currently completing the integration of this business with our operations. If our integration is unsuccessful, more difficult or more time consuming than originally planned, we may incur unexpected disruptions to our ongoing business. These disruptions could harm our operating results. Further, the following specific factors may adversely affect our ability to integrate the FPGA business of Agere:

• we may experience unexpected losses of key employees or customers;

• we may not achieve expected levels of revenue growth;

• we may not be able to coordinate our new product and process development in a way which permits us to bring future new products to the market in a timely manner; and

• we may discover unexpected liabilities.

We may be unsuccessful in defining, developing or selling new products required to maintain or expand our business.

As a semiconductor company, we operate in a dynamic environment marked by rapid product obsolescence. Our future success depends on our ability to introduce new or improved silicon and

software products that meet customer needs while achieving acceptable margins. If we fail to introduce these new products in a timely manner or these products fail to achieve market acceptance, our operating results would be harmed.

The introduction of new silicon and software products in a dynamic market environment presents significant business challenges. Product development commitments and expenditures must be made well in advance of product sales. The market reception of new products depends on accurate projections of long-term customer demand, which by their nature are uncertain.

Our future revenue growth is dependent on market acceptance of our new silicon and software product families and the continued market acceptance of our current products. The success of these products is dependent on a variety of specific technical factors including:

• successful product definition;

• timely and efficient completion of product design;

• timely and efficient implementation of wafer manufacturing and assembly processes;

• product performance;

• product cost; and

• the quality and reliability of the product.

If, due to these or other factors, our new silicon and software products do not achieve market acceptance, our operating results would be harmed.

Our products may not be competitive if we are unsuccessful in migrating our manufacturing processes to more advanced technologies or alternative fabrication facilities.

To develop new products and maintain the competitiveness of existing products, we need to migrate to more advanced wafer manufacturing processes that use larger wafer sizes and smaller device geometries. We also may need to use additional foundries. Because we depend upon foundries to provide their facilities and support for our process technology development, we may experience delays in the availability of advanced wafer manufacturing process technologies at existing or new wafer fabrication facilities. As a result, volume production of our advanced process technologies at the fabs of Seiko Epson, UMC, Chartered Semiconductor or future foundries may not be achieved. This could harm our operating results.

In late 2001, UMC informed us that as part of an overall capacity rationalization they were planning to close certain of their fabrication facilities. We were developing an advanced wafer manufacturing process at one of the UMC fabs that has been closed. With UMC’s support, we have transferred this process to another UMC fab. However, as a result, our new product introduction schedules were delayed. This could harm our operating results.

Our marketable securities, which we hold for strategic reasons, are subject to equity price risk and their value may fluctuate.

Currently we hold substantial equity in UMC, which we acquired as part of a strategic investment to obtain certain manufacturing rights. The market price and valuation of these equity shares has fluctuated widely due to market and other conditions over which we have little control. During the year ended December 31, 2001, we recorded a $152.8 million pre-tax impairment loss related to this investment. In the future, UMC shares may continue to experience significant price volatility. In the second quarter of 2002, we sold a portion of our UMC shares, but have otherwise not attempted to reduce or eliminate this equity price risk through hedging or similar techniques and hence substantial, sustained changes in the market price of UMC shares could impact our financial results. To the extent that the market value of our UMC shares experiences a significant decline for an extended period of time, our net income could be reduced.

Our future quarterly operating results may fluctuate and therefore may fail to meet expectations.

Our quarterly operating results have fluctuated and may continue to fluctuate. Consequently, our operating results may fail to meet the expectations of analysts and investors. As a result of industry conditions and the following specific factors, our quarterly operating results are more likely to fluctuate and are more difficult to predict than a typical non-technology company of our size and maturity:

• general economic conditions in the countries where we sell our products;

• conditions within the end markets into which we sell our products;

• the cyclical nature of demand for our customers’ products;

• excessive inventory accumulation by our end customers;

• the timing of our and our competitors’ new product introductions;

• product obsolescence;

• the scheduling, rescheduling and cancellation of large orders by our customers;

• our ability to develop new process technologies and achieve volume production at the fabs of Seiko Epson, UMC, Chartered Semiconductor or at other foundries;

• changes in manufacturing yields;

• adverse movements in exchange rates, interest rates or tax rates; and

• the availability of adequate supply commitments from our wafer foundries and assembly and test contractors.

As a result of these factors, our past financial results are not necessarily a good predictor of our future results.

Our stock price may continue to experience large fluctuations.

In recent years, the price of our common stock has fluctuated greatly. These price fluctuations have been rapid and severe and have left investors little time to react. The price of our common stock may continue to fluctuate greatly in the future due to a variety of company specific factors, including:

• quarter-to-quarter variations in our operating results;

• shortfalls in revenue or earnings from levels expected by securities analysts; and

• announcements of technological innovations or new products by other companies.

Presently, our stock price is trading near our consolidated book value. A sustained decline in our stock price may result in a write-off of goodwill (see Note 9).

Our wafer supply may be interrupted or reduced, which may result in a shortage of finished products available for sale.

We do not manufacture finished silicon wafers. Currently, substantially all of our silicon wafers are manufactured by Seiko Epson in Japan, UMC in Taiwan, and Chartered Semiconductor in Singapore. If Seiko Epson, through its U.S. affiliate, Epson Electronics America, UMC or Chartered significantly interrupts or reduces our wafer supply, our operating results could be harmed.

In the past, we have experienced delays in obtaining wafers and in securing supply commitments from our foundries. At present, we anticipate that our supply commitments are adequate. However, these existing supply commitments may not be sufficient for us to satisfy customer demand in future periods. Additionally, notwithstanding our supply commitments we may still have difficulty in obtaining wafer deliveries consistent with the supply commitments. We negotiate wafer prices and supply commitments from our suppliers on at least an annual basis. If any of Seiko Epson, Epson Electronics America, UMC or Chartered Semiconductor were to reduce its supply commitment or increase its wafer prices, and we cannot find alternative sources of wafer supply, our operating results could be harmed.

Many other factors that could disrupt our wafer supply are beyond our control. Since worldwide manufacturing capacity for silicon wafers is limited and inelastic, we could be harmed by significant industry-wide increases in overall wafer demand or interruptions in wafer supply. Additionally, a future disruption of Seiko Epson’s, UMC’s or Chartered Semiconductor’s foundry operations as a result of a fire, earthquake or other natural disaster could disrupt our wafer supply and could harm our operating results.

If our foundry partners experience quality or yield problems, we may face a shortage of finished products available for sale.

We depend on our foundries to deliver reliable silicon wafers with acceptable yields in a timely manner. As is common in our industry, we have experienced wafer yield problems and delivery delays. If our foundries are unable for a prolonged period to produce silicon wafers that meet our specifications, with acceptable yields, our operating results could be harmed.

The majority of our revenue is derived from products based on a specialized silicon wafer manufacturing process technology called E²CMOS^®. The reliable manufacture of high performance E²CMOS semiconductor wafers is a complicated and technically demanding process requiring:

• a high degree of technical skill;

• state-of-the-art equipment;

• the absence of defects in the masks used to print circuits on a wafer;

• the elimination of minute impurities and errors in each step of the fabrication process; and

• effective cooperation between us and the wafer supplier.

As a result, our foundries may experience difficulties in achieving acceptable quality and yield levels when manufacturing our silicon wafers.

If our assembly and test contractors experience quality or yield problems, we may face a shortage of finished products available for sale.

We rely on contractors to assemble and test our devices with acceptable quality and yield levels. As is common in our industry, we have experienced quality and yield problems in the past. If we experience prolonged quality or yield problems in the future, our operating results could be harmed.

The majority of our revenue is derived from semiconductor devices assembled in advanced packages. The assembly of advanced packages is a complex process requiring:

• a high degree of technical skill;

• state-of-the-art equipment;

• the absence of defects in lead frames used to attach semiconductor devices to the package;

• the elimination of raw material impurities and errors in each step of the process; and

• effective cooperation between us and the assembly contractor.

As a result, our contractors may experience difficulties in achieving acceptable quality and yield levels when assembling and testing our semiconductor devices.

Deterioration of conditions in Asia may disrupt our existing supply arrangements and result in a shortage of finished products available for sale.

All three of our major silicon wafer suppliers operate fabs located in Asia. Our finished silicon wafers are assembled and tested by independent contractors located in China, Malaysia, the Philippines, South Korea and Taiwan. A prolonged interruption in our supply from any of these contractors could harm our operating results.

Economic, financial, social and political conditions in Asia have historically been volatile. Financial difficulties, governmental actions or restrictions, prolonged work stoppages or any other difficulties experienced by our suppliers may disrupt our supply and could harm our operating results.

Our wafer purchases from Seiko Epson are denominated in Japanese yen. The value of the dollar with respect to the yen fluctuates. Substantial deterioration of dollar-yen exchange rates could harm our operating results.

Export sales account for a substantial portion of our revenues and may decline in the future due to economic and governmental uncertainties.

Our export sales are affected by unique risks frequently associated with foreign economies including:

• changes in local economic conditions;

• exchange rate volatility;

• governmental controls and trade restrictions;

• export license requirements and restrictions on the export of technology;

• political instability or terrorism;

• changes in tax rates, tariffs or freight rates;

• interruptions in air transportation; and

• difficulties in staffing and managing foreign sales offices.

For example, our export sales have historically been affected by regional economic crises. Significant changes in the economic climate in the foreign countries where we derive our export sales could harm our operating results.

We may not be able to successfully compete in the highly competitive semiconductor industry.

The semiconductor industry is intensely competitive and many of our direct and indirect competitors have substantially greater financial, technological, manufacturing, marketing and sales resources. If we are unable to compete successfully in this environment, our future results will be adversely affected.

The current level of competition in the programmable logic market is high and may increase in the future. We currently compete directly with companies that have licensed our technology or have developed similar products. We also compete indirectly with numerous semiconductor companies that offer products and solutions based on alternative technologies. These direct and indirect competitors are established multinational semiconductor companies as well as emerging companies. We also may experience significant competition from foreign companies in the future.

We may fail to retain or attract the specialized technical and management personnel required to successfully operate our business.

To a greater degree than most non-technology companies or larger technology companies, our future success depends on our ability to attract and retain highly qualified technical and management personnel. As a mid-sized company, we are particularly dependent on a relatively small group of key employees. Competition for skilled technical and management employees is intense within our industry. As a result, we may not be able to retain our existing key technical and management personnel. In addition, we may not be able to attract additional qualified employees in the future. If we are unable to retain existing key employees or are unable to hire new qualified employees, our operating results could be adversely affected.

If we are unable to adequately protect our intellectual property rights, our financial results and competitive position may suffer.

Our success depends in part on our proprietary technology. However, we may fail to adequately protect this technology. As a result, we may lose our competitive position or face significant expense to protect or enforce our intellectual property rights.

We intend to continue to protect our proprietary technology through patents, copyrights and trade secrets. Despite this intention, we may not be successful in achieving adequate protection. Claims allowed on any of our patents may not be sufficiently broad to protect our technology. Patents issued to us also may be challenged, invalidated or circumvented. Finally, our competitors may develop similar technology independently.

Companies in the semiconductor industry vigorously pursue their intellectual property rights. If we become involved in protracted intellectual property disputes or litigation we may utilize substantial financial and management resources, which could have an adverse effect on our operating results.

Our industry is characterized by frequent claims regarding patents and other intellectual property rights of others. We have been, and from time-to-time expect to be, notified of claims that we are infringing the intellectual property rights of others. If any third party makes a valid claim against us, we could face significant liability and could be required to make material changes to our products and processes.

In response to any claims of infringement, we may seek licenses under patents that we are alleged to be infringing. However, we may not be able to obtain a license on favorable terms or without our operating results being adversely affected.

New Accounting Pronouncements

In June 2001, the FASB issued SFAS 142, which supersedes APB Opinion No. 17, “Intangible Assets.” SFAS 142, among other things, establishes new standards for intangible assets acquired in a business combination, eliminates amortization of goodwill and sets forth requirements to periodically evaluate goodwill for impairment. We adopted this statement during the first quarter of 2002 and thus goodwill and certain intangibles with indefinite lives are no longer being amortized. To apply SFAS 142, a company is divided into separate “reporting units,” each representing groups of products that are separately managed. For this purpose, we have one reporting unit. To determine whether or not goodwill may be impaired, a test is required comparing the book value of the “reporting unit” to its trading price. Similar tests are required in the future, at least annually, and more often where there is a change in circumstances that could result in an impairment of goodwill. If the trading price of our common stock is below the book value for a sustained period, a goodwill impairment test will be performed by comparing book value to estimated market value (trading price plus a control premium). The excess of book value over estimated market value will then be subtracted from the goodwill account with a resulting charge to operations. Subsequent unrealized recoveries in market value, if any, will not be recorded. We completed an initial goodwill impairment assessment as of January 1, 2002 to determine if a transition impairment charge should be recognized under SFAS 142. Upon assessment, no transition impairment charge was recorded. Additional goodwill impairment tests will be performed at least annually.

The following tables present details of the Company’s total purchased intangible assets (in millions):

June 30, 2003	Gross		Accumulated amortization			Net

2003 (remaining six months)	$	35.7
2004	43.8
2005	14.4

quarter of 2003, we extinguished $3.0 million of these notes for approximately the same amount of cash including accrued interest, at approximately carrying cost. As specified in SFAS 145, gains recognized were recorded in “Other (expense) income, net” in the accompanying Consolidated Statement of Operations.

Liquidity and Capital Resources

As of June 30, 2003, our principal source of liquidity was $470.2 million of cash and short-term investments an increase of $193.3 million from the balance of $276.9 million at December 31, 2002. This increase was due primarily to the receipt of $195.0 million in the second quarter of 2003 in conjunction with the issuance of $200 million of our Zero Coupon Convertible Subordinated Notes (see Note 14). This, plus cash generated from operations, more than offset $29.9 million and $3.0 million in cash used during the first and second quarters of 2003, respectively, to extinguish a portion of our existing 4¾% convertible debt. Working capital increased to $518.3 million at June 30, 2003 from $348.8 million at December 31, 2002. This increase was also primarily due to the issuance of new convertible notes discussed above.

Accounts receivable at June 30, 2003 increased by $2.0 million, or eight percent, as compared to the balance at December 31, 2002. This increase was primarily due to the timing of billings and payments during the quarter as compared to the fourth quarter of 2002. Inventories decreased by $8.0 million, or 14%, as compared to the balance at December 31, 2002. This decrease was primarily due to reduced starts and receipts of wafers in response to continued lower revenue levels. Other current assets decreased by $23.6 million, or 67%, as compared to the balance at December 31, 2002. This was primarily due to the receipt of federal income tax refunds approximating $28.1 million related to the carryback of 2002 net operating losses to prior profitable periods. Foundry investments, advances and other assets increased by $4.1 million, or four percent. This increase was primarily due to approximately $5.5 million in fees and estimated issuance costs recorded in connection with the issuance of our Zero Coupon Convertible Subordinated Notes. Intangible assets, net, decreased by $35.6 million, or 23% as compared to the balance at December 31, 2002, substantially due to amortization during the first six months of 2003. Deferred income on sales to distributors decreased by $3.2 million, or 27%, as compared to the balance at December 31, 2002. This decrease was primarily due to lower shipments and billings to the distributors, resulting in lower inventories at the distributors.

On June 20, 2003, we issued $200 million in Zero Coupon convertible subordinated notes due on July 1, 2010. No interest will accrue or be payable related to these notes. Holders of these notes may

convert the notes into shares of our common stock at any time before the close of business on the date of their maturity, unless the notes have been previously redeemed or repurchased, if (1) the price of our common stock issuable upon conversion of a note reaches a specified threshold, (2) the notes are called for redemption, (3) specified corporate transactions occur or (4) the trading price of the notes falls below certain thresholds. The conversion price is approximately $12.06 per share, subject to adjustment in certain circumstances. On or after July 1, 2008, we have the option to redeem all or a portion of the notes that have not been previously repurchased or converted at 100% of the principal amount of the notes. On July 1, 2008, holders have the option to require us to purchase all or a portion of their notes in cash at 100% of the principal amount of the notes. The notes are subordinated in right of payment to all of our senior indebtedness, and are subordinated by operation of law to all liabilities of our subsidiaries. At June 30, 2003, we had no senior indebtedness and our subsidiaries had approximately $2.3 million of debt and other liabilities outstanding. Issuance costs relative to these convertible notes are included in “Foundry investments, advances and other assets” and aggregated approximately $5.5 million and are being amortized to expense over the lives of the notes. Accumulated amortization of these issuance costs was not significant as of June 30, 2003.

We do not have any financial partnerships with unconsolidated entities, such as entities often referred to as structured finance or special purpose entities, which are often established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Accordingly, we are not exposed to any financing, liquidity, market or credit risk that could arise if we had such relationships.

Capital expenditures were approximately $5.7 million for the first six months of 2003. We expect to spend approximately $10 million to $15 million for the fiscal year ending December 31, 2003.

We currently own approximately 88.2 million shares of UMC common stock. Restrictions by UMC and the Taiwan government apply to approximately 23.3 million of these shares (see Note 11). During 2002, we sold approximately 7.6 million of our UMC shares for approximately $9.9 million in cash, resulting in a gain of $4.0 million. In the future, we may or may not choose to liquidate additional UMC shares.

In December 2000, our Board of Directors authorized management to repurchase up to five million shares of our common stock. As of December 31, 2002, we had repurchased 1,136,000 shares (596,000 in 2001) at an aggregate cost of approximately $20.0 million ($10.6 million in 2001). There were no repurchases of common stock in 2002 or the first six months of 2003.

In March 1997 and as subsequently amended in January 2002, we entered into an advance payment production agreement with Seiko Epson and Epson Electronics America, Inc. (“EEA”) under which we agreed to advance up to approximately $69 million, payable upon completion of specific milestones, to Seiko Epson to finance construction of an eight-inch sub-micron semiconductor wafer manufacturing facility. Under the terms of the agreement, the advance is to be repaid with semiconductor wafers over a multi-year period. No interest income is recorded. The agreement calls for wafers to be supplied by Seiko Epson through EEA pursuant to purchase agreements with EEA. Payments of approximately $51.3 million have been made under this agreement. Cumulatively, approximately $14.1 million of these payments have been repaid to us in the form of semiconductor wafers. Approximately $3.5 million of the outstanding advances are expected to be repaid with semiconductor wafers during the next twelve months and are thus reflected as part of Prepaid expenses and Other current assets in our Consolidated Balance Sheet. We do not anticipate making additional payments under this agreement.

We believe that our existing liquid resources, expected cash generated from operations and existing credit facilities combined with our ability to borrow additional funds will be adequate to meet our operating and capital requirements and obligations for the next 12 months.

We may in the future seek new or additional sources of funding. In addition, in order to secure additional wafer supply, we may from time to time consider various financial arrangements including joint ventures, equity investments, advance purchase payments, loans, or similar arrangements with independent wafer manufacturers in exchange for committed wafer capacity. To the extent that we pursue any such additional financing arrangements, additional debt or equity financing may be required. There can be no assurance that such additional financing will be available when needed or, if available, will be on favorable terms. Any future equity financing will decrease existing stockholders’ equity percentage ownership and may, depending on the price at which the equity is sold, result in dilution.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

As of June 30, 2003 and December 31, 2002 our investment portfolio consisted of fixed income securities of $468.4 million and $274.4 million, respectively. As with all fixed income instruments, these securities are subject to interest rate risk and will decline in value if market interest rates increase. If market rates were to increase immediately and uniformly by 10% from levels as of June 30, 2003 and December 31, 2002, the decline in the fair value of our portfolio would not be material. Further, we have the ability to hold our fixed income investments until maturity and, therefore, we would not expect to recognize such an adverse impact in our income or cash flows.

We have international subsidiary and branch operations. Additionally, a portion of our silicon wafer purchases are denominated in Japanese yen. We therefore are subject to foreign currency rate exposure. To mitigate rate exposure with respect to our yen-denominated wafer purchases, we maintain a yen-denominated bank account and bill our Japanese customers in yen. If the foreign currency rates were to fluctuate by 10% from rates at either June 30, 2003 or December 31, 2002, the effect on our consolidated financial statements would not be material. However, there can be no assurance that there will not be a material impact in the future.

We are exposed to equity price risk due to our equity investment in UMC (see Note 11). Neither a 10% increase nor a 10% decrease in equity price related to this investment would have a material effect on our consolidated financial statements. We have not attempted to reduce or eliminate this equity price risk through hedging or similar techniques. As a result, sustained changes in the market price of UMC shares could impact our financial results. To the extent that the market value of our UMC shares experiences further deterioration for an extended period of time, our net income could be reduced.

Item 4. Controls and Procedures

(a) Evaluation of disclosure controls and procedures. Within the 90-day period prior to the date of this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-14(c) and 15d – 14(c) of the Securities Exchange Act of 1934 (the “Exchange Act”)). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective in ensuring that information required to be disclosed by the 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 Securities and Exchange Commission’s rules and forms.

(b) Changes in internal controls. There have been no significant changes in our internal controls or in other factors which could significantly affect our internal controls subsequent to the date we carried out our evaluation, including any corrective actions with regard to significant deficiencies and material weaknesses.
