ITEM 1.

BUSINESS

We are a fabless semiconductor company that focuses on providing highly efficient power amplification to the digital media consumer electronics and communications markets. We design and sell digital amplifiers based on our proprietary technology, called Digital Power Processing®, which enables us to provide significant performance, power efficiency, size and weight advantages over traditional amplifier technology. Our digital amplifiers are branded “Class-T®” and combine a switching mode approach that generates high fidelity sound with low distortion and considerably lower heat dissipation than Class-AB amplifiers. We target and provide digital amplifiers for three primary markets where signal fidelity and power efficiency are important: Consumer Electronics, Digital Subscriber Line (“DSL”) and Wireless. Within the Consumer Electronics market, we target multiple market segments, which include consumer audio applications such as 5.1 – 7.1 channel home theater systems, flat panel televisions, personal computers, mini/micro component stereo systems, cable set-top boxes and gaming consoles, automotive audio applications such as in-dash head units and trunk amplifiers and professional audio applications such as audio distribution systems and pro-audio amplifiers. We are currently offering digital amplifiers in the form of line drivers for use in DSL equipment. We also have a research and development program aimed at developing amplifiers for digital wireless handsets and base stations to increase talk time and battery life and improve overall power efficiency.

We were incorporated in California in July 1995, and reincorporated in Delaware in July 2000. We became a public reporting company in August 2000, and our stock is currently listed on the National NASDAQ market under the stock symbol “TRPH”. Our principal executive office is located at 2560 Orchard Parkway, San Jose, CA 95131. Our telephone number is (408) 750-3000, and our Internet home page is located at www.tripath.com; however, the information in, or that can be accessed through, our home page is not part of this report. Our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to such reports are available, free of charge, on our Internet home page as soon as reasonably practicable after we electronically file such material with, or furnish it to, the Securities and Exchange Commission, or SEC.

Markets and Products

We develop and supply digital amplifiers for three primary markets: Consumer Electronics, DSL and Wireless. Within the Consumer Electronics market, we target the consumer audio and automotive audio market segments. Within the DSL market, we have recently begun offering single and dual channel line driver products. Within the Wireless market, we have a research and development program aimed at developing a family of amplifier products for use in wireless handsets, also known as Radio Frequency (“RF”) Power Amplifiers.

Consumer Electronics - Consumer Audio Amplifiers

We provide a broad range of digital audio amplifiers based on our Digital Power Processing (“DPP®”) technology. Manufacturers are incorporating our digital audio amplifiers in a diverse set of applications, including 5.1 – 7.1 channel home theater systems, flat panel televisions, professional amplifiers, DVD and A/V receivers, personal computers, mini/micro component stereo systems, cable set-top boxes and gaming consoles.

The key factors that differentiate our products are the broad range of power levels, the input format to the amplifier and the level of integration included in our products. We augment our products with applications support that includes reference designs, evaluation kits and consulting services. All of our products share similar characteristics in terms of high efficiencies and excellent sound quality as measured by total harmonic distortion (“THD”).

Because of the broad range of product offering we have in our digital amplifiers, we have created specific products to appeal to high-powered applications such as DVD and A/V receivers as well as pro-audio amplifiers. Our proprietary technology helps realize clear sound, almost half the energy consumption of conventional professional amplifiers and natural heat dissipation without a cooling fan.

We offer three categories of digital audio amplifier products, fully integrated audio amplifiers, amplifier drivers and chipsets. In our integrated products, the actual power output transistors are included in the single integrated circuit package. These products currently support power levels of up to two channels of 100 watts per channel. At levels greater than 100 watts per channel, we offer driver products that include our proprietary DPP® signal processing integrated circuit and a high voltage integrated circuit that drives a range of external power transistors. The use of external power transistors is required at these power levels due to the heat dissipation limitations of a single integrated circuit package. We offer driver products with power capability that ranges from 100 watts to 2000 watts and chipset products with power capability that ranges from 50 watts to 350 watts. We use a four ohm load for reference when we specify power.

Our products support analog inputs to be compatible with existing analog amplifier systems. In some applications, a digital input to the amplifier is preferred and we are responding to the market needs by developing several new audio amplifiers with digital input. The first of those devices, the TCD6000 was announced in 2003 and is currently in the sampling phase of its product life cycle.

The digital input format that we plan to support across the product line in the table below is referred to as I²S. In this interface, the digital content is encoded in a format that is specified by the I²S standard.

In September 2003, we announced the introduction of a new breakthrough low cost power stage architecture platform, based on “CMOS” processes, which we refer to as “Godzilla” that can be used across the broad spectrum of audio amplifiers from 10 Watt per channel PC stereo to greater than 150 Watt per channel audio video receivers. We believe that this new architecture will enable us to reduce our manufacturing costs in the future and help us compete more effectively with traditional analog amplifiers and other digital solutions.

In January 2004, we announced our first four amplifier devices based on the new Godzilla, CMOS process and we are currently sampling these devices with various customers. These four devices can deliver a wide range of power from 50 up to 200 Watts per channel. Volume production on all four devices is expected to begin during the third quarter of 2004.

Consumer Electronics - Automotive Audio Amplifiers

Because of their ability to decrease the size and weight of audio systems and lower heat dissipation, our products can be used in applications in automotive audio systems where these issues are critical. Our proprietary technology allows products to generate high fidelity sound with significantly lower heat dissipation making it ideal for compact design applications. We currently offer products specifically targeted for automotive applications such as in-dash head units and trunk amplifiers.

We currently sell two products that are specifically targeted at the automotive market: the TA 2041, a 4 channel x 70 Watt digital audio amplifier, and the recently announced TAA4100, the World’s first 4 channel x 100 Watt digital audio amplifier in a single package.

The table below summarizes our consumer electronics (consumer audio and automotive) products that we are currently selling.

Total Harmonic Distortion, or THD, measures the change in a signal as it is amplified, expressed as a percentage of a pure input signal. The more accurate an amplifier is, the lower its THD will be.

DSL Line Driver Amplifiers

Our DPP® technology allows us to produce highly linear amplifiers for line cards that use power more efficiently than traditional amplifiers with conventional architectures. DSL amplifiers are often called line drivers. Because our line drivers are more power efficient, they eliminate the heat sink and other electronic components associated with traditional line drivers. As a result, our line drivers can be smaller than traditional line drivers. In addition, their efficiency makes them a more attractive solution for DSL service providers because the power budgeted for the equipment in such service providers’ central offices is fixed.

Our initial product is a line driver for use in the Asymmetric DSL (“ADSL”) market. ADSL, a popular form of DSL technology, is designed to allow greater data rates from the central office to the subscriber than from the subscriber to the central office. This means that typical users will be able to download data faster than they can send data, which is suitable for most residential users. In February 2001, we announced our entry into the ADSL chipset market with a new family of central office ADSL line drivers. These new products offer full reach and data rate capability and can reduce heat dissipation substantially versus conventional line drivers. Our line driver configurations feature:

	•	power consumption of approximately 680mW per channel

	•	support for full rate and G. LITE data rates

	•	low distortion specifications

	•	low power mode

	•	digitally programmable gain

	•	small footprint package

Our DSL line drivers offer DSL service providers the following benefits:

	•	Higher Port Density. Our line drivers enable our customers to increase the number of subscriber lines given fixed power and space constraints. This allows DSL service providers to achieve higher port density.

	•	Increased Signal Reach and Connection Speed. The distance a signal can travel with an effective usefulness is known as signal reach, and the speed at which data can be transferred is known as connection speed. Intermodulation Distortion (“IMD”), is a measure of linearity and indicates how well an amplifier can reduce the impact of undesirable frequencies which are produced in the transmission process. Our line drivers, due to their linearity, can more accurately reproduce the signal inputs, allowing for improvements in output signal reach and connection speed to the consumer.

The following table provides additional information concerning the specifications of our current and future generation of DSL line drivers.

Product	Power Consumption (milliwatts/channel)	Application

TLD4012 Single channel family	680mW	Central office ADSL line driver
TLD4021 Dual channel family	500mW	Central office ADSL line driver

We started to ship our TLD4012 DSL line driver in volume during the first half of 2003 and we are in the sampling phase of our new dual channel line driver.

RF/Wireless Power Amplifiers

Our expertise in the development of highly linear and energy efficient circuits has allowed us to develop an amplifier architecture which we believe is well-suited for use in digital handsets, base stations and other wireless products. The initial targeted market is for cellular phones that utilize a digital transmission method known as Code Division Multiple Access (“CDMA”). Linearity is important to this technology because CDMA uses a complex signal transmission method that requires more accurate reception and reproduction. Additionally, we believe our DPP® technology could provide significant improvements to the design of cellular phones in terms of talk-time, data connection time and battery size, which are all dependent on the efficiency of the RF Power Amplifier. We are currently working with two companies in this area who are in the early stages of evaluating our technology.

Core Technology

We believe that one of our key competitive advantages is our broad base of patented core technologies, which are comprised of innovative adaptive and predictive signal processing techniques. These processing techniques are derived from algorithms used in communications theories. These unique techniques are derived from a confluence of four primary disciplines in mixed signal circuit design, digital signal processing (“DSP”), algorithm development, power semiconductor circuit design and packaging design. We intend to continue to build and improve on these four primary technology foundations as we expand our product reach into other markets and industries.

We have implemented unique processing algorithms in a silicon-based processor which we call a Mixed Signal Processor. The execution speed of these complex algorithms by our Mixed Signal Processor allows us to achieve the required linearity and efficiency in our products. The Mixed Signal Processor functionality is a vital component in the architecture of the products we design.

Our core technologies are characterized by four key areas of competency highlighted below:

Mixed Signal Circuit Design Expertise

We are an innovator in advanced mixed signal circuit design including audio amplifiers, DSL line driver amplifiers and RF Power Amplifiers. We have developed significant intellectual property in our mixed signal circuit designs, which are applicable across multiple market segments. As such, we have demonstrated significant improvements in power efficiency and linearity for audio amplifiers and central office line driver integrated circuits. We are also applying this same core technology to the development of highly linear and highly efficient RF Power Amplifier integrated circuits for incorporation in cellular telephones.

DSP Algorithm Expertise

We have expertise in developing system applications using our DPPâ technology. This includes industry standard designs as well as customer specific systems in the DSL and Consumer Electronics markets. The high efficiency, high quality power processing products that we design require a comprehensive understanding of new and innovative DSP techniques at the system as well as the device level. We will continue to research and improve our DPPâ technology.

Power Semiconductor Circuit Design Expertise

We have developed significant expertise in designing power circuits in semiconductors. This requires a specialized understanding of complex issues, such as thermal effects and reliability related to the control of power.

Packaging Design Expertise

We have developed significant competency and knowledge regarding packaging requirements for various applications in different markets. Our customers have specific requirements in terms of form factor and package type for their end-use products.

Research and Development

Our research and development efforts are focused on developing products based on our DPP® technology for high growth markets, such as the consumer audio, DSL and wireless communications markets. As of December 31, 2003, our research and development staff consisted of 36 employees, many of whom have experience across multiple engineering disciplines. In 2003, 2002 and 2001, our research and development expenses were approximately $6.9 million, $11.7 million and $19.9 million, respectively.

Manufacturing

Wafer Fabrication

We are able to use independent silicon foundries to manufacture our integrated circuits because our products are manufactured with standard processes. By outsourcing our manufacturing requirements, we are able to focus our resources on design engineering.

Our operations group closely manages the interface between manufacturing, design engineering and sales. The group provides manufacturing support required for test and product engineering, process and device engineering, package engineering, reliability, quality assurance and production control. We maintain our organizational structure and quality standards to match with market leading semiconductor manufacturers. We use an online work-in-progress control methodology wherever possible, and maintain close reporting mechanisms with all of our suppliers to ensure that the manufacturing subcontracting process is transparent to our customers.

Our key silicon foundries are United Microelectronics Corporation in Taiwan, STMicroelectronics Group in Europe and Renesas Technology (Mitsubishi Electric) in Japan. We believe we have adequate capacity to support our current sales levels. We continue to work with our existing foundries to obtain more production capacity and we are actively qualifying new foundries to procure additional production capacity.

Our Mixed Signal Processor and high voltage power devices are currently manufactured with Complementary Metal Oxide Semiconductor (“CMOS”) and Diffusion Metal Oxide Semiconductor (“DMOS”) processes using >0.18 micron technology. CMOS and DMOS are industry standard semiconductor manufacturing processes. We continuously evaluate the benefits, on a product by product basis, of migrating to smaller design technologies to reduce costs and improve performance.

In September 2003, we announced the introduction of a new breakthrough low cost power stage architecture platform, based on “CMOS” processes, which we refer to as “Godzilla” that can be used across the broad spectrum of audio amplifiers from 10 Watt per channel PC stereo to greater than 150 Watt per channel audio video receivers. We believe that this new architecture will enable us to reduce our manufacturing costs and continue to improve our gross margins during the latter part of 2004 and during 2005.

Assembly and Test

We currently outsource all of our assembly and testing operations to AMBIT Microsystems Corporation in China, Amkor Technology, Inc. in the Philippines, Advanced Semiconductor Engineering (“ASE”) in Korea, Malaysia and Taiwan, Lingsen in Taiwan, STS (formerly ISE Labs Assembly) in China, ST Assembly Test Services Ltd. in Singapore and ST Microelectronics Group in Malaysia.

Quality Assurance

We currently rely on our foundries and assembly subcontractors to assist in the qualification process of our products. We also participate in quality and reliability monitoring through each stage of the production cycle. We closely monitor wafer foundry production, assembly and test manufacturing operations to ensure consistent overall quality, reliability and yield levels.

Marketing, Sales and Customers

Our marketing strategy is to target existing and potential customers who are industry leaders in the consumer electronics (consumer, automotive and professional audio), DSL communications and wireless communications markets. Currently, our sales and marketing effort is primarily focused on market segments, divided among integrated audio products and module-based driver products, and separately divided among the flat panel TV, home theater, PC, gaming, professional and automotive audio.

We rely on our direct sales force and distributors to sell our products in our target markets. Approximately 73% of our sales were through distributors in 2003 compared to 67% in 2002.

Our sales headquarters is located in San Jose, California. In addition, we market and sell our products through our regional offices located in Japan and Hong Kong, as well as through independent distributors in Asia, Europe and the United States. We incorporated our regional office in Japan as a wholly-owned subsidiary in January 2001. Our sales force, together with our engineering and technical staff, works closely with customers to integrate our amplifiers into their products. We believe that close working relationships with customers will help us to achieve design wins and ultimately achieve high volume production.

End customers for our products are primarily manufacturers of audio electronic components, communications infrastructure equipment and wireless communications equipment. Three, two and four end customers accounted for more than 10% of our sales in 2003, 2002 and 2001, respectively. The customers who accounted for more than 10% of our sales in 2003 were Kyoshin Technosonic Co., Ltd., (KTS), Samsung Electronics Co., Ltd. (Samsung) and Apple Computer.

For a detailed description of our sales by geographic region, see Note 2 (Segment and geographic information) to our consolidated financial statements.

Competition

We currently compete with a number of larger companies in the consumer audio amplifier market. While our technology offers distinct advantages over the analog approach, we believe that approximately only 2-3 percent of the market has converted to digital audio amplifiers at this time. The primary analog amplifier competitors in the market today are National Semiconductor, Philips Electronics, ST Microelectronics and Texas Instruments. Philips, ST Microelectronics and Texas Instruments are also our major competitors in the digital audio amplifier market. In addition, a number of companies, such as Cirrus Logic Inc., have announced their intention to enter this market. We have been active in the audio amplifier market since our inception and we believe that we maintain a strong competitive position.

In the DSL line driver market, our principal competitors include Analog Devices, Inc., Intersil Corporation, Linear Technology Corporation and Texas Instruments Incorporated. This is a new market for us in which many of our competitors have longer operating histories.

We believe that the principal factors of competition in these markets are product capabilities, level of integration, reliability, price, power consumption, time-to-market, system cost, intellectual property, customer support and reputation.

In each of these markets, we believe that our main competitive advantages are our product capabilities, low power consumption, high signal fidelity and level of integration. However, many of our competitors are large public companies that have longer operating histories and significantly greater resources than us. As a result, these competitors may compete favorably on factors such as price, customer support and reputation.

Intellectual Property

We rely primarily on a combination of patent, copyright, trademark, trade secret and other intellectual property laws, nondisclosure agreements and other protective measures to protect our proprietary technologies and processes. We have 32 issued United States patents and 12 additional pending United States patent applications. In addition, we have 16 international patents issued and an additional 29 international patents pending. We expect to continue to file patent applications where appropriate to protect our proprietary technologies. To our knowledge, no patents have been contested by third parties thus far.

Employees

As of December 31, 2003, we had 56 full-time employees, including 36 employees engaged in research and development, 9 engaged in sales and marketing and 11 engaged in general administration activities. None of our employees are represented by a labor union and we have never experienced a work stoppage. We consider our employee relations to be good.

As of February 23, 2004 there were 289 holders of record of our common stock. Because many of our shares of common stock are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by these record holders.

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion and analysis in conjunction with the “Selected Financial Data” and the financial statements and notes thereto included in this Annual Report on Form 10-K. Historical operating results are not necessarily indicative of results that may occur in future periods. This discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. The actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, including, but not limited to, those presented under “Risk Factors” and elsewhere in this annual report on Form 10-K. We undertake no obligation to update any forward-looking statement to reflect events after the date of this report.

Overview

We design and sell digital amplifiers based on our proprietary Digital Power Processing (DPPâ) technology. We currently supply amplifiers for audio electronics applications, and have begun offering amplifiers for DSL applications. We were incorporated in July 1995, began shipping products in the first quarter of 1998 and became a public reporting company in August 2000. Accordingly, we have limited historical financial information and operating history for use in evaluating Tripath and our future prospects. We incurred net losses of approximately $7.2 million in 2003, $19.3 million in 2002 (before charge for beneficial conversion of $14.9 million) and $27.0 million in 2001. We expect to continue to incur net losses in 2004, and possibly beyond.

We sell our products to original equipment manufacturers and distributors. We recognize revenue from product sales upon shipment to original equipment manufacturers, net of sales returns and allowances. Our sales to distributors are made under arrangements allowing for returns or credits under certain circumstances and we defer recognition on sales to distributors until products are resold by the distributor to the end user. All of our sales are made in United States (“U.S.”) dollars.

As a “fabless” semiconductor company, we contract with third party semiconductor fabricators to manufacture the silicon wafers based on our integrated circuit (“IC”) designs. Each wafer contains numerous die, which are cut from the wafer to create a chip for an IC. We also contract with third party assembly and test houses to assemble and package our die and conduct final product testing.

Cost of revenue includes the cost of purchasing finished silicon wafers and die manufactured by independent foundries, costs associated with assembly and final product testing, as well as salaries and overhead costs associated with employees engaged in activities related to manufacturing. Research and development expense consists primarily of salaries and related overhead costs associated with employees engaged in research, design and development activities, as well as the cost of wafers and other materials and related services used in the development process. Selling, general and administrative expense consists primarily of employee compensation and related overhead expenses and advertising and marketing expenses.

Stock-based compensation expense relates both to stock-based employee and consultant compensation arrangements. Employee-related stock-based compensation expense is based on the difference between the estimated fair value of our common stock on the date of grant and the exercise price of options to purchase that stock and is being recognized on an accelerated basis over the vesting periods of the related options, usually four years, or in the case of fully vested options, in the period of grant. Consultant stock-based compensation expense is based on the Black-Scholes option pricing model. Future compensation charges will be reduced if any employee or consultant terminates employment or consultation prior to the expiration of the option vesting period.

Critical Accounting Policies

Use of Estimates: Management’s discussion and analysis of financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to product returns, warranty obligations, bad debts, inventory direct costing and valuation, accruals, valuation of stock options and warrants, income taxes (including the valuation allowance for deferred taxes) and restructuring costs. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from the other sources. Actual results may materially differ from these estimates under different assumptions or conditions. Material differences may occur in our results of operations for any period if we made different judgments or utilized different estimates.

Revenue Recognition: We recognize revenue in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 104 (“SAB 104”), “Revenue Recognition in Financial Statements”. We recognize revenue when all of the following criteria are met: 1) there is persuasive evidence that an arrangement exists, 2) delivery of goods has occurred, 3) the sales price is fixed or determinable, and 4) collectibility is reasonably assured. The following policies apply to our major categories of revenue transactions. Sales to OEM Customers: Under our standard terms and conditions of sale, title and risk of loss transfer to the customer at the time product is delivered to the customer, FOB shipping point, and revenue is recognized accordingly. We accrue the estimated cost of post-sale obligations, including basic product warranties or returns, based on historical experience. We have experienced minimal warranty or other returns to date. Sales to Distributors: We provide our distributors certain incentives such as stock rotation, price protection, and other offerings. As a result of these incentives, we defer recognition of revenue until such time that the distributor sells product to its customer.

Allowance for Doubtful Accounts: We provide an allowance for doubtful accounts to ensure trade receivables are not overstated due to uncollectibility. The collectibility of our receivables is evaluated based on a variety of factors, including the length of time receivables are past due, customers’ indication of willingness to pay, significant one-time events and historical experience. An additional reserve for individual accounts is recorded when we become aware of a customer’s inability to meet its financial obligations, such as in the case of bankruptcy filings or substantial deterioration in the customer’s operating results or financial position. If circumstances related to our customers change, estimates of the recoverability of receivables would be further adjusted.

Inventories: Inventories are stated at the lower of cost or market. This policy requires us to make estimates regarding the market value of our inventory, including an assessment of excess or obsolete inventory. We determine excess and obsolete inventory based on an estimate of the future demand and estimated selling prices for our products within a specified time horizon, generally 12 months. The estimates we use for expected demand are also used for near-term capacity planning and inventory purchasing and are consistent with our revenue forecasts. In addition to current inventory of $5.6 million, we have inventory purchase commitments of approximately $3.2 million. Our inventory and purchase commitments are based on expected demand and not necessarily built for firm purchase commitments for our customers. Because of the required delivery lead time, we need to carry a high level of inventory in comparison to past sales. Actual demand and market conditions may be different from those projected by our management. If our unit demand forecast is less than our current inventory levels and purchase commitments, during the specified time horizon, or if the estimated selling price is less than our inventory value, we will be required to take additional excess inventory charges or write-downs to net realizable value which will decrease our gross margin and net operating results in the future. During the quarter ended March 31, 2002, we recorded a provision for excess inventory of approximately $5 million related to excess inventory for our TA2022 product as a result of a decrease in forecasted sales for this product.

Results of Operations

Years Ended December 31, 2003, 2002 and 2001

Revenue. Revenues for fiscal year 2003 were $13.9 million, a decrease of $2.3 million or 14% from revenues of $16.2 million for fiscal year 2002. The decrease in revenues was primarily due to decreases in sales of our TA2022, TA3020 and TK2050 products, reflecting lower sales of low margin home theater products in the China market and decreased demand from Apple Computer, partially offset by increases in sales of our TLD4012 and TA2024 products reflecting increased sales of DSL line drivers and digital audio amplifier products in the flat panel TV and gaming vertical markets. Revenues for fiscal year 2002 increased by $2.7 million or 20% over revenues of $13.5 million for fiscal year 2001. The increase in revenues resulted primarily from increased sales of our TA2024, TA3020 and TK2050 products, offset partially by decreased sales of our TA1101B and TA2022 products.

Our top five end customers accounted for 68% of revenue in 2003 versus 67% and 82% in 2002 and 2001 respectively. Our primary customers in 2003 were Kyoshin Technosonic Co., Ltd. (KTS), Samsung Electronics Co., Ltd. (Samsung) and Apple Computer Inc. (“Apple“), representing 24%, 18% and 15% of revenue, respectively. In 2002 our primary customers were Apple Computer Inc. and Apex Digital inc., representing 31% and 19% of revenue, respectively. Sony Corporation and Apple Computer Inc. were our top two customers in 2001, representing 29% and 25% of revenue, respectively.

Gross Profit (Loss). Gross profit for fiscal year 2003 was $4.2 million (including stock-based compensation expense of $4,000) compared to a gross loss of $2.3 million (including stock-based compensation expense of $23,000) for fiscal year 2002 and a gross profit of $1.6 million (including stock-based compensation benefit of $95,000) for fiscal year 2001. The increase in gross profit for fiscal year 2003 reflects ongoing product cost reduction efforts, increased unit volumes for a number of our products as well as sales of higher margin products. The gross loss for fiscal year 2002 was primarily due to a reserve of $5.0 million for excess inventory during the first quarter of 2002. The inventory charge, related to excess inventory for our TA2022 product, was based on a decline in forecasted sales for this product.

Research and Development. Research and development (R&D) expenses for fiscal year 2003 were $6.9 million (including stock-based compensation expense of $20,000), a decrease of $4.8 million or 41% from R&D expenses of $11.7 million (including stock-based compensation expense of $195,000) for fiscal year 2002. The decrease in R&D expenses was due to a decrease in personnel costs, as a result of reduced headcount and salary reductions, and a decrease in product development expenses, as well as lower rent and insurance expenses.. R&D expenses for fiscal year 2001 totaled $19.9 million (including stock-based compensation benefit of $133,000). The decrease in R&D expenses from 2001 to 2002 was due to lower personnel related costs and lower product development costs. We anticipate that our R&D expenses will increase in fiscal 2004.

Selling, General and Administrative Expenses. Selling, general and administrative (S,G&A) expenses for fiscal year 2003 were $4.5 million (including stock-based compensation expense of $57,000), a decrease of $1.1 million or 20% from S,G&A expenses of $5.6 million (including stock-based compensation benefit of $502,000) in 2002. The decrease in S,G&A expenses was primarily due to decreased headcount and related costs and lower expenses related to rent, insurance and bad debts. S,G&A expenses for fiscal year 2001 were $8.7 million (including stock-based compensation expense of $488,000). The decrease in S,G&A expenses from 2001 to 2002 was primarily due to decreased headcount and related costs and lower professional services costs. We anticipate that our S,G&A expenses will increase in fiscal 2004, including expenses for legal and financial compliance costs related to the Sarbanes-Oxley Act of 2002 and increased insurance costs.

Restructuring and Other Charges. On August 3, 2001, we announced a restructuring and cost reduction plan which included a workforce reduction and write-off of abandoned assets. As a result of the restructuring and cost reduction plan, we recorded restructuring and other charges of $684,000 during the quarter ended September 30, 2001. Under the restructuring and cost reduction plan, we reduced our workforce by approximately 40 employees across all functions and mostly located at our former headquarters facility in Santa Clara, California. The workforce reduction resulted in a $164,000 charge relating primarily to severance and fringe benefits for terminated employees. We also abandoned assets for a charge of $520,000. The restructuring was completed by December 31, 2001.

A summary of the restructuring and other charges is as follows:

	Total charges		Non-cash charges		Cash payments

Work force reduction	$	164,000	$	—	$	164,000
Write-off of abandoned assets		520,000		520,000		—

	$	684,000	$	520,000	$	164,000

Interest and Other Income, net. Interest income for 2003 was $22,000, a decrease of $138,000 or 86% from interest income of $160,000 in 2002. Interest income for 2002 decreased $527,000 or 77% from interest income of $687,000 in 2001. The decreases in interest income in 2003 and 2002 resulted from decreases in our average cash equivalents and short-term investment balances to fund operations, together with lower interest rates.

Accretion on Preferred Stock. Accretion on Preferred Stock for 2002 was $14,952,000. The accretion was due to the financing transaction that was completed in January 2002, in which we raised $21 million in gross proceeds through a private placement of non-voting Series A Preferred Stock and warrants. The accretion related to the beneficial conversion feature represents the difference between the accounting conversion price and the fair value of the common stock on the date of the transaction, after valuing the warrants issued in connection with the financing transaction.

Income Taxes.We have incurred no income tax expense to date. As of December 31, 2003, we had available federal net operating loss carryforwards of approximately $106 million and state net operating loss carryforwards of approximately $35 million. We also had research and development tax credit carryforwards of approximately $5 million for federal and state purposes. The net operating loss and credit carryforwards will expire at various times through 2021. As of December 31, 2003, we had deferred tax assets of approximately $48 million which consisted primarily of net operating loss carryforwards, research and development tax credit carryforwards and nondeductible reserves and accruals. We have recorded a full valuation allowance against these deferred tax assets. Deferred tax assets will be recognized in future periods as any taxable income is realized and consistent profits are reported.

Liquidity and Capital Resources

Since our inception, we have financed our operations through the private sale of our equity securities, primarily the sale of preferred stock, through our initial public offering on August 1, 2000 and through a private placement in January 2002 and subsequent stock warrant exercises. Net proceeds to us as a result of our initial public offering, our 2002 private placement and subsequent stock warrant exercises were approximately $45.4 million, $19.9 million and $5.4 million, respectively.

Net cash used by operating activities decreased by $8.9 million from $13.0 million for the year ended December 31, 2002 to $4.1million for the year ended December 31, 2003. The decrease was mainly due to a decrease in net loss of $12.1 million primarily as a result of lower operating expenses, partially offset by a decrease in the provision for excess inventory of $4.7 million and an increase in accounts payable of $1.7 million. Net cash used for operating activities during the year ended December 31, 2001 was $32.5 million, the majority of which was used to fund the net loss of $27 million and inventory purchases of $7.6 million.

Cash used in investing activities was $487,000 for the year ended December 31, 2003 compared with $201,000 for the year ended December 31, 2002. The change was primarily due to no cash being provided from the sale of short term investments during 2003 whereas $1.1 million had been provided from the sale of short term investments during 2002. In 2001 our investing activities provided cash in the amount of $22.1 million from the net sale of short-term investments.

Cash provided by financing activities decreased by $15.7 million from $19.4 million for the year ended December 31, 2002 to $3.4 million for the year ended December 31, 2003. The higher amount of cash provided by financing activities in 2002 was due to the additional financing, details of which are summarized below. In 2001, our financing activities provided cash in the amount of $1.8 million, the majority of which was derived from proceeds from issuance of common stock under our Employee Stock Purchase Plan and through exercise of stock options.

On January 24, 2002, we completed a financing in which we raised $21 million in gross proceeds through a private placement of non-voting Series A Preferred Stock and warrants, at $30 per unit to a group of investors. At a Special Meeting of Stockholders held on March 7, 2002, our stockholders approved the issuance and sale of the Series A Preferred Stock and warrants, which then automatically converted into 13,999,000 shares of common stock and warrants to purchase 3,303,760 shares of common stock. This included unregistered warrants that were issued to the placement agent for the financing transaction to purchase 503,960 shares of our common stock. The 2,799,800 registered warrants have a term of three years and an effective Common Stock exercise price of $1.95 per share, whereas 419,968 of the 503,960 warrants issued to the placement agent have an effective Common Stock exercise price of $1.50 per share. The remainder of the warrants issued to the placement agent have an effective Common Stock exercise price of $1.95 per share.

During the year ended December 31, 2003, warrants were exercised which resulted in the issuance of 1,896,226 shares of our common stock with proceeds totaling approximately $3.1 million. The warrants issued to the placement agent were exercised on a net issuance basis resulting in 300,438 shares of our common stock being issued to the placement agent.

The warrant agreement contained a provision for the mandatory exercise of the warrants if our common stock traded at $5.85 or higher for 20 out of 30 trading days. At the close of business on January 2, 2004 our common stock had traded at $5.85 or higher for 20 consecutive days and we were able to invoke the provision for the mandatory exercise of all outstanding warrants issued in connection with the January 2002 financing. All outstanding warrants were exercised in January 2004 resulting in the issuance of an additional 1.2 million shares of common stock. We received proceeds of approximately $2.3 million from the exercise of these warrants.

On July 12, 2002, we entered into a credit agreement with a financial institution that provided for a one-year revolving credit facility in an amount of up to $10 million, subject to certain restrictions in the borrowing base based on eligibility of receivables. The credit agreement expired on June 30, 2003 and was not renewed.

The credit agreement was used to issue stand-by letters of credit totaling $1.7 million to collateralize our obligations to a third party for the purchase of inventory and to provide a security deposit for the lease of new office space. Upon the expiration of the credit agreement on June 30, 2003, we entered into a Pledge and Security Agreement to provide a security interest in a money market account in the amount of $0.7 million for the standby letters of credit, which totaled $0.7 million at December 30, 2003.

Our total potential commitments on our operating and capital leases and inventory purchases as of December 31, 2003, were as follows (in thousands):

Year Ending December 31,	Operating Leases		Capital Leases			Inventory Purchase Commitments		Totals

2004	$	933	$	551		$	3,235	$	4,719
2005		1,083		494			—		1,577
2006		1,046		86			—		1,132
2007		270		—			—		270
2008 and beyond		—		—			—		—

	$	3,332		1,131		$	3,235	$	7,698

Less: amount representing interest				(76	)

Present value of minimum lease payments				1,055
Less: current portion of capital lease obligations				(496	)

Long-term capital lease obligations			$	559

We expect our future liquidity and capital requirements will fluctuate depending on numerous factors including: market acceptance and demand for current and future products, the timing of new product introductions and enhancements to existing products, the success of on-going efforts to reduce our manufacturing costs as well as operating expenses and need for working capital for such items as inventory and accounts receivable.

We have incurred substantial losses and have experienced negative cash flow since inception and have an accumulated deficit of $179.6 million at December 31, 2003. Beginning in August 2001, we instituted programs to reduce expenses including reducing headcount from 144 employees at the end of July 2001 to 56 employees at the end of December 2003 and reducing employees salaries by 10%. In September 2002 we relocated our headquarters which reduced rent expense and canceled our D&O policy which reduced insurance expense. These actions resulted in significant cost savings in 2003. We reduced our cash used in operating activities from approximately $13 million in 2002 to approximately $4 million in 2003.

During 2003, warrants were exercised which resulted in us receiving proceeds totaling approximately $3.1 million. At December 31, 2003, we had working capital of $11.2 million, including cash of $9.6 million. Subsequent to December 31, 2003 we received proceeds of approximately $2.3 million from the exercise of outstanding warrants.

We may need to raise additional funds to finance our activities through public or private equity or debt financings, the formation of strategic partnerships or alliances with other companies or through bank borrowings with existing or new banks. We may not be able to obtain additional funds on terms that would be favorable to our stockholders and us, or at all. In such instance, we will take measures to reduce our operating expenses, such as reducing headcount or canceling selected research and development projects. Without sufficient capital to fund our operations, we will no longer be able to continue as a going concern. We believe, based on our current cash balance as well as our ability to implement the aforementioned measures, if needed, that we will have liquidity sufficient to meet our operating, working capital and financing needs for the next twelve months and perhaps beyond. Our long-term prospects are dependent upon obtaining sufficient financing as needed to fund current working capital needs and future growth, and ultimately on achieving profitability.

Recent Accounting Pronouncements

In January 2003, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 46, “Consolidation of Variable Interest Entities, an Interpretation of ARB No. 51” (“FIN 46”), which addresses consolidation by business enterprises of variable interest entities (VIEs) either: (1) that do not have sufficient equity investment at risk to permit the entity to finance its activities without additional subordinated financial support, or (2) in which the equity investors lack an essential characteristic of a controlling financial interest. In December 2003, the FASB completed deliberations of proposed modifications to FIN 46 (Revised Interpretations) resulting in multiple effective dates based on the nature as well as the creation date of the VIE. VIEs created after January 31, 2003, but prior to January 1, 2004, may be accounted for either based on the original interpretation or the Revised Interpretations. However, the Revised Interpretations must be applied no later than the first quarter of fiscal year 2004. VIEs created after January 1, 2004 must be accounted for under the Revised Interpretations. There has been no material impact to our consolidated financial statements from potential VIEs entered into after January 31, 2003 and there is no expected impact from the adoption of the deferred provisions in the first quarter of fiscal year 2004.

In June 2003, the FASB issued Statement of Financial Accounting Standards (“SFAS”) No. 149, “Amendment of Statement 133 on Derivative Instruments and Hedging Activities” (“SFAS 149”). SFAS 149 amends and clarifies financial accounting and reporting for derivative instruments and for hedging activities. SFAS 149 is effective for contracts entered into or modified after June 30, 2003. We do not use derivative products and the adoption of this statement had no material impact on our consolidated financial statements.

In June 2003, the FASB issued SFAS No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity (“SFAS 150”).” SFAS 150 establishes standards on the classification and measurement of certain financial instruments with characteristics of both liabilities and equity. The provisions of SFAS 150 are effective for financial instruments entered into or modified after May 31, 2003 and to all other instruments that exist as of the beginning of the first interim financial reporting period beginning after June 15, 2003. The adoption of SFAS 150 did not have a material impact on our results of operations or financial position.

In December 2003, the SEC issued Staff Accounting Bulletin No. 104, “Revenue Recognition” (“SAB 104”), which codifies, revises and rescinds certain sections of SAB No. 101, Revenue Recognition, in order to make this interpretive guidance consistent with current authoritative accounting and auditing guidance and SEC rules and regulations. The changes noted in SAB 104 did not have a material effect on our consolidated results of operations, consolidated financial position or consolidated cash flows.

Risk Factors

Set forth below and elsewhere in this annual report and in the other documents we file with the Securities and Exchange Commission are risks and uncertainties that could cause actual results to differ materially from the results contemplated by the forward looking statements contained in this annual report. Prospective and existing investors are strongly urged to carefully consider the various cautionary statements and risks set forth in this annual report and our other public filings.

Our limited operating history and dependence on new technologies make it difficult to evaluate our prospects and future products.

We were incorporated in July 1995, began shipping products in 1998 and became a public reporting company in August 2000. Accordingly, we have limited historical financial information and operating history upon which you may evaluate us and our products. Our prospects must be considered in the light of the risks, challenges and difficulties frequently encountered by companies in their early stage of development, particularly companies in intensely competitive and rapidly evolving markets such as the semiconductor industry. We cannot be sure that we will be successful in addressing these risks and challenges.

We have a history of losses and may never achieve or sustain profitability.

As of December 31, 2003, we had an accumulated deficit of $179.6 million. We incurred net losses of approximately $7.2 million in 2003, $19.3 million (before accretion on preferred stock of $14.9 million) in 2002 and $27.0 million in 2001. We may continue to incur net losses and these losses may be substantial. Furthermore, we may continue to generate significant negative cash flow in the future. We will need to generate substantially higher revenue to achieve and sustain profitability and positive cash flow. Our ability to generate future revenue and achieve profitability will depend on a number of factors, many of which are described throughout this section. If we are unable to achieve or maintain profitability, we will be unable to build a sustainable business. In this event, our share price and the value of your investment would likely decline and we might be unable to continue as a going concern.

We may need to raise additional capital to continue to grow our business, which may not be available to us.

Because we have had losses, we have funded our operating activities to date from the sale of securities, including our most recent financing in January 2002 as well as from the proceeds from the related exercise of warrants issued in connection with the 2002 financing. However, to grow our business significantly, we will need additional capital. We cannot be certain that any such financing will be available on acceptable terms, or at all. Moreover, additional equity financing, if available, would likely be dilutive to the holders of our common stock, and debt financing, if available, would likely involve restrictive covenants. If we cannot raise sufficient additional capital, it would adversely affect our ability to achieve our business objectives and to continue as a going concern.

Our quarterly operating results are likely to fluctuate significantly and may fail to meet the expectations of securities analysts and investors, which may cause our share price to decline.

Our quarterly operating results have fluctuated significantly in the past and are likely to continue to do so in the future. The many factors that could cause our quarterly results to fluctuate include, in part:

	•	level of sales and recognition of revenue;

	•	mix of high and low margin products;

	•	availability and pricing of wafers;

	•	timing of introducing new products, including, but not limited to, the introduction of new products based on the lower cost “Godzilla” architecture, lower cost versions of existing products, fluctuations in manufacturing yields and other problems or delays in the fabrication, assembly, testing or delivery of products; and

	•	rate of development of target markets.

A large portion of our operating expenses, including salaries, rent and capital lease expenses, are fixed. If we experience a shortfall in revenues relative to our expenses, we may be unable to reduce our expenses quickly enough to offset the reduction in revenues during that accounting period, which would adversely affect our operating results. Fluctuations in our operating results may also result in fluctuations in our common stock price. If the market price of our stock is adversely affected, we may experience difficulty in raising capital or making acquisitions. In addition, we may become the object of securities class action litigation. As a result, we do not believe that period-to-period comparisons of our revenues and operating results are necessarily meaningful. One should not rely on the results of any one quarter as an indication of future performance.

Our stock price may be subject to significant volatility.

The stock prices for many technology companies have recently experienced large fluctuations, which may or may not be directly related to the operating performance of the specific companies. For example, for fiscal 2003, our Common Stock had closing sales prices on Nasdaq as low as $0.17 and as high as $7.02 per share. Broad market fluctuations as well as general economic conditions may cause our stock price to decline. We believe that fluctuations of our stock price may continue to be caused by a variety of factors, including:

	•	announcements of developments related to our business;

	•	fluctuations in our financial results;

	•	general conditions in the stock market or around the world, terrorism or developments in the semiconductor and capital equipment industry and the general economy;

	•	sales or purchases of our common stock in the marketplace;

	•	announcements of our technological innovations or new products or enhancements or those of our competitors;

	•	developments in patents or other intellectual property rights;

	•	developments in our relationships with customers and suppliers;

	•	a shortfall or changes in revenue, gross margins or earnings or other financial results from analysts’ expectations or an outbreak of hostilities or natural disasters; or

	•	acquisition or merger activity and the success in implementing such acquisitions.

Our product shipment patterns make it difficult to predict our quarterly revenues.

As is common in our industry, we frequently ship more products in the third month of each quarter than in either of the first two months of the quarter, and shipments in the third month are higher at the end of that month. We believe this pattern is likely to continue. The concentration of sales in the last month of the quarter may cause our quarterly results of operations to be more difficult to predict. Moreover, if sufficient business does not materialize or a disruption in our production or shipping occurs near the end of a quarter, our revenues for that quarter could be materially reduced.

Our customers may cancel or defer product orders, which could result in excess inventory.

Our sales are generally made pursuant to individual purchase orders that may be canceled or deferred by customers on short notice without significant penalty. Thus, orders in backlog may not result in future revenue. In the past, we have had cancellations and deferrals by customers. Any cancellation or deferral of product orders could result in us holding excess inventory, or result in obsolete inventory over time, which could seriously harm our profit margins and restrict our ability to fund our operations. For example, during the quarter ended March 31, 2002, we recorded a provision for excess inventory of approximately $5.0 million. Our inventory and purchase commitments are based on expected demand and not necessarily built for firm purchase commitments for our customers. Because of the required delivery lead time, we need to carry a high level of inventory in comparison to past sales. We recognize revenue upon shipment of products to the end customer. Although we have not experienced customer refusals to accept shipped products or material difficulties in collecting accounts receivable, such refusals or collection difficulties are possible and could result in significant charges against income, which could seriously harm our revenues and our cash flow.

We rely on a small number of customers for most of our revenue and a decrease in revenue from these customers could seriously harm our business.

A relatively small number of customers have accounted for most of our revenues to date. Any reduction or delay in sales of our products to one or more of these key customers could seriously reduce our sales volume and revenue and adversely affect our operating results. Our top five end customers accounted for 68% of revenue in 2003 versus 67% and 82% in 2002 and 2001 respectively. Our primary customers in 2003 were Kyoshin Technosonic Co., Ltd. (KTS), Samsung Electronics Co., Ltd. (Samsung), and Apple Computer Inc. (“Apple”) representing 24%, 18% and 15% of revenue, respectively. In 2002 our primary customers were Apple and Apex Digital inc., representing 31% and 19% of revenue, respectively. Sony Corporation and Apple were our top two customers in 2001, representing 29% and 25% of revenue, respectively. We expect that we will continue to rely on the success of our largest customers and on our success in selling our existing and future products to those customers in significant quantities. However, we cannot be sure that we will retain our largest customers or that we will be able to obtain additional key customers or replace key customers we may lose or who may reduce their purchases.

We currently rely on sales of four products for a significant portion of our revenue, and the failure of these products to be successful in the future could substantially reduce our sales.

We currently rely on sales of our TA1101B, TA2020, TA2024 digital audio amplifier products and TLD4012 DSL line driver to generate a significant portion of our revenue. Sales of these products amounted to 87% of our revenue for year ended December 31, 2003, 96% of our revenue in 2002 and 94% of our revenue in 2001. We have developed additional products and plan to introduce more products in the future, but there can be no assurance that these products will be commercially successful. Consequently, if our existing products are not successful, our sales could decline substantially.

Our lengthy sales cycle makes it difficult for us to predict if or when a sale will be made, to forecast our revenue and to budget expenses, which may cause fluctuations in our quarterly results.

Because of our lengthy sales cycles, we may continue to experience a delay between incurring expenses for research and development, sales and marketing and general and administrative efforts, as well as incurring investments in inventory, and the generation of revenue, if any, from such expenditures. In addition, the delays inherent in such a lengthy sales cycle raise additional risks of customer decisions to cancel or change product plans, which could result in our loss of anticipated sales. Our new products are generally incorporated into our customers’ products or systems at the design stage. To try and have our products selected for design into new products of current and potential customers, commonly referred to as design wins, often requires significant expenditures by us without any assurance of success. Once we have achieved a design win, our sales cycle will start with the test and evaluation of our products by the potential customer and design of the customer’s equipment to incorporate our products. Generally, different parts have to be redesigned to incorporate our devices successfully into our customers’ products.

The sales cycle for the test and evaluation of our products can range from a minimum of three to six months, and it can take a minimum of an additional six to nine months before a customer commences volume production of equipment that incorporates our products. Achieving a design win provides no assurance that such customer will ultimately ship products incorporating our products or that such products will be commercially successful. Our revenue or prospective revenue would be reduced if a significant customer curtails, reduces or delays orders during our sales cycle, or chooses not to release products incorporating our products.

Our ability to achieve revenue growth will be harmed if we are unable to persuade electronic systems manufacturers to adopt our new amplifier technology.

We face difficulties in persuading manufacturers to adopt our products using our new amplifier technology. Traditional amplifiers use design approaches developed in the 1930s. These approaches are still used in most amplifiers and engineers are familiar with these design approaches. To adopt our products, manufacturers and engineers must understand and accept our new technology. To take advantage of our products, manufacturers must redesign their systems, particularly components such as the power supply and heat sinks. Manufacturers must work with their suppliers to obtain modified components and they often must complete lengthy evaluation and testing. In addition, our amplifiers are often more expensive as components than traditional amplifiers. For these reasons, prospective customers may be reluctant to adopt our technology.

We currently depend on consumer electronics markets that are typically characterized by aggressive pricing, frequent new product introductions and intense competition.

A substantial portion of our current revenue is generated from sales of products that address the consumer electronics markets, including home theater, computer audio, flat panel TV, gaming, professional amplifiers, set-top box, AV receivers and the automotive audio markets. These markets are characterized by frequent new product introductions, declining prices and intense competition. Pricing in these markets is aggressive, and we expect pricing pressure to continue. In the computer audio segment, our success depends on consumer awareness and acceptance of existing and new products by our customers and consumers, in particular, the elimination of externally-powered speakers. In the automotive audio segment, we face pressure from our customers to deliver increasingly higher-powered solutions under significant engineering limitations due to the size constraints in car dashboards. In addition, our ability to obtain prices higher than the prices of traditional amplifiers will depend on our ability to educate manufacturers and their customers about the benefits of our products. Failure of our customers and consumers to accept our existing or new products will seriously harm our operating results.

The cyclical nature of the semiconductor industry could create fluctuations in our operating results.

The semiconductor industry has historically been cyclical and characterized by wide fluctuations in product supply and demand. From time to time, the industry has also experienced significant downturns, often in connection with, or in anticipation of, maturing product cycles and declines in general economic conditions. Industry downturns have been characterized by diminished product demand, production overcapacity and accelerated decline in average selling prices, and in some cases have lasted for more than a year. The industry experienced a downturn of this type in 1997 and 1998, and began experiencing a downturn again in 2001. In addition, we may determine to lower our prices of our products to increase or maintain market share, which would likely harm our operating results. The semiconductor industry also periodically experiences increased demand and production capacity constraints. As a result, we have experienced and may experience in the future substantial period-to-period fluctuations in our results of operations due to general semiconductor industry conditions, overall economic conditions or other factors, many of which are outside our control. Due to these risks, you should not rely on period-to-period comparisons to predict our future performance.

We may experience difficulties in the introduction of new or enhanced products, including but not limited to the new “Godzilla” architecture products, that could result in significant, unexpected expenses or delay their launch, which would harm our business.

Our failure or our customers’ failure to develop and introduce new products successfully and in a timely manner would seriously harm our ability to generate revenues. Consequently, our success depends on our ability to develop new products for existing and new markets, introduce such products in a timely and cost-effective manner and to achieve design wins. The development of these new devices is highly complex, and from time to time we have experienced delays in completing the development and introduction of new products. The successful introduction of a new product may currently take up to 18 months. Successful product development and introduction depends on a number of factors, including:

	•	accurate prediction of market requirements and evolving standards;

	•	accurate new product definition;

	•	timely completion and introduction of new product designs;

	•	availability of foundry capacity;

	•	achieving acceptable manufacturing yields;

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

	•	market competition.

We cannot guarantee success with regard to these factors.

We depend on three outside foundries for our semiconductor device manufacturing requirements.

We do not own or operate a fabrication facility, and substantially all of our semiconductor device requirements are currently supplied by three outside foundries, United Microelectronics Corporation, in Taiwan, STMicroelectronics Group in Europe and Renesas Technology (Mitsubishi Electric) in Japan. Although we primarily utilize these three outside foundries, most of our components are not manufactured at these foundries at the same time. As a result, each foundry is a sole source for certain products.

There are significant risks associated with our reliance on outside foundries, including:

	•	the lack of guaranteed wafer supply;

	•	limited control over delivery schedules, quality assurance and control, manufacturing yields and production costs; and

	•	the unavailability of or delays in obtaining access to key process technologies.

In addition, the manufacture of integrated circuits is a highly complex and technologically demanding process. Although we work closely with our foundries to minimize the likelihood of reduced manufacturing yields, our foundries have from time to time experienced lower than anticipated manufacturing yields, particularly in connection with the introduction of new products and the installation and start-up of new process technologies.

We provide our foundries with continuous forecasts of our production requirements; however, the ability of each foundry to provide us with semiconductor devices is limited by the foundry’s available capacity. In many cases, we place our orders on a purchase order basis, and foundries may allocate capacity to the production of other companies’ products while reducing the deliveries to us on short notice. In particular, foundry customers that are larger and better financed than us or that have long-term agreements with our foundries may cause such foundries to reallocate capacity in a manner adverse to us. While capacity at our foundries has been available during the last several years, the cyclical nature of the semiconductor industry could result in capacity limitations in a cyclical upturn or otherwise.

If we use a new foundry, several months would be typically required to complete the qualification process before we can begin shipping products from the new foundry. In the event any of our current foundries suffers any damage or destruction to their respective facilities, or in the event of any other disruption of foundry capacity, we may not be able to qualify alternative manufacturing sources for existing or new products in a timely manner. Even our current outside foundries would need to have certain manufacturing processes qualified in the event of disruption at another foundry, which we may not be able to accomplish in a timely enough manner to prevent an interruption in supply of the affected products.

If we encounter shortages or delays in obtaining semiconductor devices for our products in sufficient quantities when required, delivery of our products could be delayed, resulting in customer dissatisfaction and decreased revenues.

We depend on third-party subcontractors for most of our semiconductor assembly and testing requirements and any unexpected interruption in their services could cause us to miss scheduled shipments to customers and to lose revenues.

Semiconductor assembly and testing are complex processes, which involve significant technological expertise and specialized equipment. As a result of our reliance on third-party subcontractors for assembly and testing of our products, we cannot directly control product delivery schedules, which has in the past, and could in the future, result in product shortages or quality assurance problems that could increase the costs of manufacture, assembly or testing of our products. Almost all of our products are assembled and tested by one of seven subcontractors: AMBIT Microsystems Corporation in China, Amkor Technology, Inc. in the Philippines, ASE in Korea, Malaysia and Taiwan, Lingsen in Taiwan, STMicroelectronics Group in Malaysia, STS in China, and ST Assembly Test Services Ltd. in Singapore. We do not have long-term agreements with any of these suppliers and retain their services on a per order basis. The availability of assembly and testing services from these subcontractors could be adversely affected in the event a subcontractor suffers any damage or destruction to their respective facilities, or in the event of any other disruption of assembly and testing capacity. Due to the amount of time normally required to qualify assemblers and testers, if we are required to find alternative manufacturing assemblers or testers of our components, shipments could be delayed. Any problems associated with the delivery, quality or cost of our products could seriously harm our business.

Failure to transition our products to more effective and/or increasingly smaller semiconductor chip sizes and packaging could cause us to lose our competitive advantage and reduce our gross margins.

We evaluate the benefits, on a product-by-product basis, of migrating to smaller semiconductor process technologies in order to reduce costs and have commenced migration of some products to smaller semiconductor processes. We believe that the transition of our products to increasingly smaller semiconductor processes will be important for us to reduce manufacturing costs and to remain competitive. Moreover, we are dependent on our relationships with our foundries to migrate to smaller semiconductor processes successfully. We cannot be sure that our future process migrations will be achieved without difficulties, delays or increased expenses. Our gross margins would be seriously harmed if any such transition is substantially delayed or inefficiently implemented.

Our international operations subject us to risks inherent in doing business on an international level that could harm our operating results.

We currently obtain almost all of our manufacturing, assembly and test services from suppliers located outside the United States and may expand our manufacturing activities abroad. Approximately 78% of our total revenue for the year ended December 31, 2003, was derived from sales to end customers based outside the United States. In 2002 and 2001, 61% and 72%, respectively, of our total revenue was derived from sales to end customers based outside of the United States. In addition, we often ship products to our domestic customers’ international manufacturing divisions and subcontractors.

Accordingly, we are subject to risks inherent in international operations, which include:

	•	political, social and economic instability;

	•	trade restrictions and tariffs;

	•	the imposition of governmental controls;

	•	exposure to different legal standards, particularly with respect to intellectual property;

	•	import and export license requirements;

	•	unexpected changes in regulatory requirements; and

	•	difficulties in collecting receivables.

All of our international sales to date have been denominated in U.S. dollars. As a result, an increase in the value of the U.S. dollar relative to foreign currencies could make our products less competitive in international markets. Conversely, a decrease in the value of the U.S. dollar relative to foreign currencies would increase the cost of our overseas manufacturing, which would reduce our gross margins.

If we are not successful in developing and marketing new and enhanced products for the DSL high speed communications markets that keep pace with technology and our customers’ needs, our operating results will suffer.

The market for our DSL products is new and emerging, and is characterized by rapid technological advances, intense competition and a relatively small number of potential customers. This will likely result in price erosion on existing products and pressure for cost-reduced future versions. We recently started to ship our TA4012 DSL line driver in volume and are in the sampling phase of our new dual channel line driver. Implementation of our products require manufacturers to accept our technology and redesign their products. If potential customers do not accept our technology or experience problems implementing our devices in their products, our products could be rendered obsolete and our business would be harmed. If we are unsuccessful in introducing future products with enhanced performance, our ability to achieve revenue growth will be seriously harmed.

We may experience difficulties in the development and introduction of a new amplifier product for use in the cellular phone market, which could result in significant expenses or delay in its launch.

We are currently developing an amplifier product for use in the cellular phone market. We currently have no design wins or customers for this product. We may not introduce our amplifier product for the cellular phone market on time, and this product may never achieve market acceptance. Furthermore, competition in this market is likely to result in price reductions, shorter product life cycles, reduced gross margins and longer sales cycles compared with what we have experienced to date with our other products.

Intense competition in the semiconductor industry and in the consumer electronics and communications markets could prevent us from achieving or sustaining profitability.

The semiconductor industry and the consumer audio and communications markets are highly competitive. We compete with a number of major domestic and international suppliers of semiconductors in the consumer electronics and communications markets. We also may face competition from suppliers of products based on new or emerging technologies. Many of our competitors operate their own fabrication facilities and have longer operating histories and presence in key markets, greater name recognition, access to larger customer bases and significantly greater financial, sales and marketing, manufacturing, distribution, technical and other resources than us. As a result, such competitors may be able to adapt more quickly to new or emerging technologies and changes in customer requirements or devote greater resources to the promotion and sale of their products than us. Current and potential competitors have established or may establish financial or strategic relationships among themselves or with existing or potential customers, resellers or other third parties. Accordingly, it is possible that new competitors or alliances among competitors could emerge and rapidly acquire significant market share. In addition, existing or new competitors may in the future develop technologies that more effectively address the transmission of digital information through existing analog infrastructures at a lower cost or develop new technologies that may render our technology obsolete. There can be no assurance that we will be able to compete successfully in the future against our existing or potential competitors, or that our business will not be harmed by increased competition.

Our products are complex and may have errors and defects that are detected only after deployment in customers’ products, which may harm our business.

Products such as those that we offer may contain errors and defects when first introduced or as new versions are released. We have in the past experienced such errors and defects, in particular in the development stage of a new product. Delivery of products with production defects or reliability, quality or compatibility problems could significantly delay or hinder market acceptance of such products, which could damage our reputation and seriously harm our ability to retain our existing customers and to attract new customers and therefore impact our revenues. Moreover, such errors and defects could cause problems, interruptions, delays or a cessation of sales to our customers. Alleviating such problems may require substantial redesign, manufacturing and testing which would result in significant expenditures of capital and resources. Despite testing conducted by us, our suppliers and our customers, we cannot be sure that errors and defects will not be found in new products after commencement of commercial production. Such errors and defects could result in additional development costs, loss of, or delays in, market acceptance, diversion of technical and other resources from our other development efforts, product repair or replacement costs, claims by our customers or others against us or the loss of credibility with our current and prospective customers. Any such event could result in the delay or loss of market acceptance of our products and would likely harm our business.

If we are unable to retain key personnel, we may not be able to operate our business successfully.

We may not be successful in retaining executive officers and other key management and technical personnel. A high level of technical expertise is required to support the implementation of our technology in our existing and new customers’ products. In addition, the loss of the management and technical expertise of Dr. Adya S. Tripathi, our founder, president and chief executive officer, could seriously harm us. We do not have any employment contracts with our employees.

Our intellectual property and proprietary rights may be insufficient to protect our competitive position.

Our business depends, in part, on our ability to protect our intellectual property. We rely primarily on patent, copyright, trademark and trade secret laws to protect our proprietary technologies. We cannot be sure that such measures will provide meaningful protection for our proprietary technologies and processes. As of December 31, 2003, we have 32 issued United States patents, and 12 additional United States patent applications which are pending. In addition, we have 16 international patents issued and an additional 29 international patents pending. We cannot be sure that any patent will issue as a result of these applications or future applications or, if issued, that any claims allowed will be sufficient to protect our technology. In addition, we cannot be sure that any existing or future patents will not be challenged, invalidated or circumvented, or that any right granted thereunder would provide us meaningful protection. The failure of any patents to provide protection to our technology would make it easier for our competitors to offer similar products. In connection with our participation in the development of various industry standards, we may be required to agree to license certain of our patents to other parties, including our competitors, that develop products based upon the adopted standards.

We also generally enter into confidentiality agreements with our employees and strategic partners, and generally control access to and distribution of our documentation and other proprietary information. Despite these precautions, it may be possible for a third party to copy or otherwise obtain and use our products, services or technology without authorization, develop similar technology independently or design around our patents. In addition, effective copyright, trademark and trade secret protection may be unavailable or limited in certain foreign countries. Some of our customers have entered into agreements with us pursuant to which such customers have the right to use our proprietary technology in the event we default in our contractual obligations, including product supply obligations, and fail to cure the default within a specified period of time.

We may be subject to intellectual property rights disputes that could divert management’s attention and could be costly.

The semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights. From time to time, we may receive in the future notices of claims of infringement, misappropriation or misuse of other parties’ proprietary rights. We cannot be sure that we will prevail in these actions, or that other actions alleging infringement by us of third-party patents, misappropriation or misuse by us of third-party trade secrets or the invalidity of one or more patents held by us will not be asserted or prosecuted against us, or that any assertions of infringement, misappropriation or misuse or prosecutions seeking to establish the invalidity of our patents will not seriously harm our business. For example, in a patent or trade secret action, an injunction could be issued against us requiring that we withdraw particular products from the market or necessitating that specific products offered for sale or under development be redesigned. We have also entered into certain indemnification obligations in favor of our customers and strategic partners that could be triggered upon an allegation or finding of our infringement, misappropriation or misuse of other parties’ proprietary rights. Irrespective of the validity or successful assertion of such claims, we would likely incur significant costs and diversion of our management and personnel resources with respect to the defense of such claims, which could also seriously harm our business. If any claims or actions are asserted against us, we may seek to obtain a license under a third party’s intellectual property rights. We cannot be sure that under such circumstances a license would be available on commercially reasonable terms, if at all. Moreover, we often incorporate the intellectual property of our strategic customers into our designs, and we have certain obligations with respect to the non-use and non-disclosure of such intellectual property.

We cannot be sure that the steps taken by us to prevent our, or our customers’, misappropriation or infringement of intellectual property will be successful.

The facilities of several of our key manufacturers and the majority of our customers, are located in geographic regions with increased risks of natural disasters.

Several key manufacturers and a majority of customers are located in the Pacific Rim region. The risk of earthquakes in this region, particularly in Taiwan, is significant due to the proximity of major earthquake fault lines. Earthquakes, fire, flooding and other natural disasters in the Pacific Rim region likely would result in the disruption of our foundry partners’ assembly and testing capacity and the ability of our customers to purchase our products. Labor strikes or political unrest in these regions would likely also disrupt operations of our foundries and customers. Any disruption resulting from such events could cause significant delays in shipments of our products until we are able to shift our manufacturing, assembly and testing from the affected contractor to another third party vendor. We cannot be sure that such alternative capacity could be obtained on favorable terms, if at all. Moreover, any such disruptions could also cause significant decreases in our sales to these customers until our customers resume normal purchasing volumes.

Terrorist attacks and threats, and government responses thereto, may negatively impact all aspects of our operations, revenues, costs and stock price.

The threat of terrorist attacks involving the United States, the instability in the Middle East, a decline in consumer confidence and continued economic weakness and geo-political instability have had a substantial adverse effect on the economy. If consumer confidence does not recover, our revenues may be adversely affected for fiscal 2004 and beyond. Moreover, any further terrorist attacks involving the U.S., or any additional U.S. military actions overseas may disrupt our operations or those of our customers and suppliers. These events have had and may continue to have an adverse impact on the U.S. and world economy in general and consumer confidence and spending in particular, which could harm our sales. Any of these events could increase volatility in the U.S.and world financial markets which could harm our stock price and may limit the capital resources available to us and our customers or suppliers. This could have a significant impact on our operating results, revenues and costs and may result in increased volatility in the market price of our common stock.

We are subject to anti-takeover provisions that could delay or prevent an unfriendly acquisition of our company.

Provisions of our restated certificate of incorporation, equity incentive plans, bylaws and Delaware law may discourage transactions involving an unfriendly change in corporate control. In addition to the foregoing, the stockholdings of our officers, directors and persons or entities that may be deemed affiliates and the ability of our board of directors to issue preferred stock without further stockholder approval could have the effect of delaying, deferring or preventing a third party from acquiring us and may adversely affect the voting and other rights of holders of our common stock.

Item 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary objective of our investment activities is to preserve principal while at the same time maximizing the income we receive from our investments without significantly increasing risk of loss. Some of the securities that we may acquire in the future may be subject to market risk for changes in interest rates. To mitigate this risk, we plan to maintain a portfolio of cash equivalents and short-term investments in a variety of securities, which may include commercial paper, money market funds, government and non-government debt securities. We manage the sensitivity of our results of operations to these risks by maintaining a conservative portfolio, which is comprised solely of highly-rated, short-term investments. We do not hold or issue derivative, derivative commodity instruments or other financial instruments for trading purposes. Currently we are exposed to minimal market risks. Due to the short-term and liquid nature of our portfolio, if interest rates were to fluctuate by 10% from rates at December 31, 2003 and December 31, 2002, our financial position and results of operations would not be materially affected.

TRIPATH TECHNOLOGY INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1—THE COMPANY AND BASIS OF PRESENTATION:

The Company

Tripath Technology Inc. (the “Company” or “Tripath”) was incorporated in California in July 1995. The Company was reincorporated in Delaware in July 2000. The Company designs, develops and markets integrated circuit devices for the Consumer Electronics, DSL and Wireless markets. On August 1, 2000, the Company completed its initial public offering of 5 million shares of common stock at $10.00 per share.

Basis of Presentation

The consolidated financial statements include the accounts of Tripath and its wholly owned subsidiary, Tripath Technology Japan Ltd. All significant intercompany accounts and transactions have been eliminated. Accounts denominated in foreign currency have been remeasured using the U.S. dollar as the functional currency.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management 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 reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates, and such differences could affect the results of operations reported in future periods and such differences could be material.

Liquidity

The Company’s consolidated financial statements have been prepared on the basis of a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has incurred substantial losses and has experienced negative cash flow since inception and has an accumulated deficit of $179.6 million at December 31, 2003.

Beginning in August 2001, the Company instituted programs to reduce expenses including reducing headcount from 144 employees at the end of July 2001 to 56 employees at the end of December 2003 and reducing employees salaries by 10%. In September 2002 the Company relocated its headquarters which reduced rent expense and canceled its D&O policy which reduced insurance expense. These actions resulted in significant cost savings in 2003. The Company reduced its cash used in operating activities from approximately $13 million in 2002 to approximately $4 million in 2003.

During 2003, warrants were exercised which resulted in the Company receiving proceeds totaling approximately $3.1 million. At December 31, 2003, the Company had working capital of $11.2 million, including cash of $9.6 million. Subsequent to December 31, 2003 the Company received proceeds of approximately $2.3 million from the exercise of outstanding warrants.

Should the Company require more cash during 2004 to fund its operations than is currently planned, management believes that such additional cash requirements could be met by first obtaining additional financing or by taking measures to reduce operating expenses such as reducing headcount or canceling research and development projects. However, the Company may not be able to obtain additional funds on terms that would be favorable to its stockholders and the Company, or at all. The Company’s long term prospects are dependent upon obtaining sufficient financing as needed to fund current working capital needs and future growth, and ultimately on achieving profitability.

The Company believes that its existing working capital at December 31, 2003, together with subsequent proceeds recovered from exercise of options and warrants will be sufficient to meet its operating, working capital, investing and financing needs for at least the next twelve months until fiscal 2005. The Company has not made any adjustment to its consolidated financial statements as a result of the outcome of the uncertainty described above.

Foreign Currency Translation

The U.S. dollar is the functional currency for the Company’s Japanese wholly-owned subsidiary. Assets and liabilities that are not denominated in the functional currency are remeasured into U.S. dollars and the resulting gains or losses are included in “Interest and other income, net.” Such gains or losses have not been material for any period presented.

NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Revenue Recognition

The Company recognizes revenue in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 104 (“SAB 104”), “Revenue Recognition in Financial Statements”. The Company recognizes revenue when all of the following criteria are met: 1) there is persuasive evidence that an arrangement exists, 2) delivery of goods has occurred, 3) the sales price is fixed or determinable, and 4) collectibility is reasonably assured. The following policies apply to the Company's major categories of revenue transactions.

Sales to OEM Customers: Under the Company’s standard terms and conditions of sale, title and risk of loss transfer to the customer at the time product is delivered to the customer, FOB shipping point, and revenue is recognized accordingly. The Company accrues the estimated cost of post-sale obligations, including basic product warranties or returns, based on historical experience. The Company has experienced minimal warranty or other returns to date.

Sales to Distributors: The Company provides its distributors certain incentives such as stock rotation, price protection, and other offerings. As a result of these incentives, the Company defers recognition of revenue until such time that the distributor sells product to its customer.

Costs related to shipping and handling are included in cost of revenue for all periods presented.

Allowance for Doubtful Accounts

The Company provides an allowance for doubtful accounts to ensure trade receivables are not overstated due to uncollectibility. The collectibility of the Company’s receivables is evaluated based on a variety of factors, including the length of time receivables are past due, indication of the customer’s willingness to pay, significant one-time events and historical experience. An additional reserve for individual accounts is recorded when the Company becomes aware of a customer's inability to meet its financial obligations, such as in the case of bankruptcy filings or substantial deterioration in the customer's operating results or financial position. If circumstances related to the Company’s customers change, estimates of the recoverability of receivables would be further adjusted.

Cash and cash equivalents and restricted cash

The Company considers all highly liquid investments with a maturity of three months or less from the date of purchase to be cash equivalents. Cash and cash equivalents consist of cash on deposit with banks, money market funds and commercial paper, bonds and notes, the fair value of which approximates cost.

The following table summarizes the Company’s cash and cash equivalents (in thousands):

		December 31,

		2003		2002

Cash and cash equivalents:
	Cash	$	1,480	$	394
	Money market funds		7,471		9,718

		$	8,951	$	10,112

The Company entered into a credit facility with a financial institution that had certain restrictions in the borrowing base. The credit facility was used to issue standby letters of credit to collateralize the Company’s obligations to a third party for the purchase of inventory and to provide a security deposit for the lease of new office space. The amount by which the aggregate face amount of all outstanding stand-by letters of credit exceeded the borrowing base, as determined by eligible receivables, represented the amount of restricted cash necessary to secure the standby letters of credit. At December 31, 2002, the Company had $486,000 in restricted cash. The credit facility expired on June 30, 2003 and was not renewed. Upon the expiration of the credit agreement on June 30, 2003, the Company entered into a Pledge and Security Agreement to provide a security interest in a money market account in the amount of $0.7 million for the standby letters of credit, which totaled $0.7 million at December 31, 2003.

Fair value of financial instruments

Carrying amounts of certain of the Company’s financial instruments, including cash and cash equivalents, accounts receivable and accounts payable, approximate their fair values due to their relative short maturities and based upon comparable market information available at the respective balance sheet dates. The Company does not hold or issue financial instruments for trading purposes.

Concentration of credit risk and significant customers

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents and short-term investments. Substantially all of the Company’s cash and cash equivalents are invested in highly-liquid money market funds. The Company sells its products through distributors and directly to original equipment manufacturers. The Company performs ongoing credit evaluations of its customers and maintains an allowance for potential credit losses, as considered necessary by management. Credit losses to date have been consistent with management’s estimates. During the years ended December 31, 2003 and December 31, 2002, the Company wrote-off bad debts which had previously been reserved totaling approximately $295,000 and $622,000, respectively. The Company had no significant write-offs or recoveries during the year ended December 31, 2001.

The following table summarizes sales to end customers comprising 10% or more of the Company’s total revenue for the periods indicated :

	% of Revenue for the Year Ended December 31,

	2003			2002			2001


Customer A		24	%		—			—
Customer B		18	%		—			—
Customer C		15	%		31	%		25	%
Customer D		—			19	%		—
Customer E		—			—			29	%
Customer F		—			—			13	%
Customer G		—			—			12	%

The Company’s accounts receivable were concentrated with five customers at December 31, 2003 representing 49%, 19%, 15%, 6% and 5% of aggregate gross receivables, five customers at December 31, 2002 representing 17%, 16%, 14%, 14% and 14% of aggregate gross receivables, and five customers at December 31, 2001 representing 15%, 15%, 13%, 12%, and 12% of aggregate gross receivables.

Inventories

Inventories are stated at the lower of cost or market. This policy requires the Company to make estimates regarding the market value of the Company’s inventory, including an assessment of excess or obsolete inventory. The Company determines excess and obsolete inventory based on an estimate of the future demand and estimated selling prices for the Company’s products within a specified time horizon, generally 12 months. The estimates the Company uses for expected demand are also used for near-term capacity planning and inventory purchasing and are consistent with the Company’s revenue forecasts. Actual demand and market conditions may be different from those projected by the Company’s management. If the Company’s unit demand forecast is less than the Company’s current inventory levels and purchase commitments, during the specified time horizon, or if the estimated selling price is less than the Company’s inventory value, the Company will be required to take additional excess inventory charges or write-downs to net realizable value which will decrease the Company’s gross margin and net operating results in the future. During the quarter ended March 31, 2002, the Company recorded a provision for excess inventory of approximately $5 million related to excess inventory for the Company’s TA2022 product as a result of a decrease in forecasted sales for this product.

Inventory purchase commitment losses

The Company accrues for estimated losses on non-cancelable purchase orders. The estimated losses result from anticipated future sale of products for sales prices less than the estimated cost to manufacture. Inventory purchase commitment losses accrued at December 31, 2003, 2002 and 2001 were $0, $38,000 and $190,000, respectively.

Research and development expenses

Research and development costs are charged to expense as incurred.

Property and equipment

Property and equipment, including leasehold improvements, are stated at historical cost, less accumulated depreciation and amortization. Amortization of leasehold improvements is computed using the straight-line method over the shorter of the estimated useful lives of the assets or the term of the lease. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows:

Furniture and fixtures	5 years
Software	Shorter of three years or term of license
Equipment	2-5 years

Long-lived assets held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that their net book value may not be recoverable. An impairment loss is recognized if the sum of the expected future cash flows (undiscounted and before interest) from the use of the assets is less than the net book value of the asset. The amount of the impairment loss, if any, will generally be measured as the difference between net book value of the assets and their estimated fair values.

Comprehensive income

Statement of Financial Accounting Standards No. 130, “Reporting Comprehensive Income,” establishes standards for reporting and displaying comprehensive income and its components in a full set of general-purposes financial statements. There was no difference between the Company’s net loss and its total comprehensive loss for the years ended December 31, 2003, 2002 and 2001.

Accounting for stock-based compensation

At December 31, 2003, the Company has two stock-based employee compensation plans, which are described more fully in Note 7. The Company accounts for those plans under the recognition and measurement principles of APB Opinion No. 25, “Accounting for Stock Issued to Employees,” and related Interpretations. No stock-based employee compensation cost related to stock options is reflected in net income for the three years ended December 31, 2003, as all options granted under those plans had an exercise price equal to the market value of the underlying common stock on the date of grant. The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of FASB Statement No. 123, “Accounting for Stock-Based Compensation”, to stock-based employee compensation.

	Year Ended December 31,

	2003			2002			2001

Net loss applicable to common stockholders, as reported	$	(7,215	)	$	(34,266	)	$	(26,981	)
Total stock-based employee compensation expense included in the net loss, determined under the recognition and measurement principles of APB Opinion No.25, net of related tax effects		(81	)		(284	)		260
Total stock-based employee compensation expense determined under fair value based method for all awards, net of related tax effects		(1211	)		(1,527	)		(5,625	)

Proforma net loss applicable to common stockholders	$	(8,507	)	$	(36,077	)	$	(32,346	)

Proforma	$	(0.20	)	$	(0.93	)	$	(1.20	)

The fair value for these options was estimated using the Black-Scholes option pricing model.

The Black-Scholes option pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. Option pricing models require the input of highly subjective assumptions, including the expected stock price volatility. Accordingly, option pricing models may not necessarily provide a reliable single measure of the fair value of options.

The fair value of options at the date of grant was estimated on the date of grant based on the method prescribed by SFAS No. 123. The following table summarizes the estimated fair value of options and assumptions used in the SFAS No. 123 calculations for stock option plans:

	Year Ended December 31,

	2003			2002			2001

Estimated fair value	$	0.73		$	0.14		$	2.21
Expected lives (in years)		5			5			5
Volatility		157	%		110	%		110	%
Risk-free interest rate		2.96	%		3.83	%		4.56	%

The following table summarizes the estimated fair value of employees’ purchase rights and assumptions used in the SFAS No. 123 calculations:

	Year Ended December 31,

	2003			2002			2001

Estimated fair value	$	0.15		$	0.38		$	0.70

Recent Accounting Pronouncements

In January 2003, the FASB issued FASB Interpretation No. 46, “Consolidation of Variable Interest Entities, an Interpretation of ARB No. 51” (“FIN 46”), which addresses consolidation by business enterprises of variable interest entities (VIEs) either: (1) that do not have sufficient equity investment at risk to permit the entity to finance its activities without additional subordinated financial support, or (2) in which the equity investors lack an essential characteristic of a controlling financial interest. In December 2003, the FASB completed deliberations of proposed modifications to FIN 46 (Revised Interpretations) resulting in multiple effective dates based on the nature as well as the creation date of the VIE. VIEs created after January 31, 2003, but prior to January 1, 2004, may be accounted for either based on the original interpretation or the Revised Interpretations. However, the Revised Interpretations must be applied no later than the first quarter of fiscal year 2004. VIEs created after January 1, 2004 must be accounted for under the Revised Interpretations. There has been no material impact to the Company’s consolidated financial statements from potential VIEs entered into after January 31, 2003 and there is no expected impact from the adoption of the deferred provisions in the first quarter of fiscal year 2004.

In June 2003, the FASB issued SFAS No. 149, “Amendment of Statement 133 on Derivative Instruments and Hedging Activities” (“SFAS 149”). SFAS 149 amends and clarifies financial accounting and reporting for derivative instruments and for hedging activities. SFAS 149 is effective for contracts entered into or modified after June 30, 2003. The Company does not use derivative products and the adoption of this statement had no material impact on the Company’s consolidated financial statements.

In June 2003, the FASB issued SFAS No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity (‘SFAS 150’).” SFAS 150 establishes standards on the classification and measurement of certain financial instruments with characteristics of both liabilities and equity. The provisions of SFAS 150 are effective for financial instruments entered into or modified after May 31, 2003 and to all other instruments that exist as of the beginning of the first interim financial reporting period beginning after June 15, 2003. The adoption of SFAS 150 did not have a material impact on the Company’s results of operations or financial position.

In December 2003, the SEC issued Staff Accounting Bulletin No. 104, “Revenue Recognition” (“SAB 104”), which codifies, revises and rescinds certain sections of SAB No. 101, Revenue Recognition, in order to make this interpretive guidance consistent with current authoritative accounting and auditing guidance and SEC rules and regulations. The changes noted in SAB 104 did not have a material effect on the Company’s consolidated results of operations, consolidated financial position or consolidated cash flows.

Net loss per share

Basic net loss per share is computed by dividing the net loss available to common stockholders for the period by the weighted average number of common stock outstanding during the period. Diluted net loss per share is computed based on the weighted average number of common stock and dilutive potential common stock outstanding. The calculation of diluted net loss per share excludes potential common stock if the effect is anti-dilutive. Potential common stock consist of incremental common stock issuable upon the exercise of stock options, shares issuable upon conversion of convertible preferred stock and common stock issuable upon the exercise of common stock warrants.

The following table sets forth the computation of basic and diluted net loss per share for the periods presented (in thousands, except per share amounts):

NOTE 3—RESTRUCTURING AND OTHER CHARGES:

On August 3, 2001, the Company announced a restructuring and cost reduction plan which included a workforce reduction and write-off of abandoned assets. As a result of the restructuring and cost reduction plan, the Company recorded restructuring and other charges of $684,000 during the quarter ended September 30, 2001.

Under the restructuring and cost reduction plan, the Company reduced its workforce by approximately 40 employees across all functions and mostly located at its former headquarters facility in Santa Clara, California. The workforce reduction resulted in a $164,000 charge relating primarily to severance and fringe benefits. The Company also abandoned assets resulting in a charge of $520,000.

A summary of the restructuring and other charges is as follows:

	Total charges		Non-cash charges		Cash payments

NOTE 5—LINE OF CREDIT:

On July 12, 2002, the Company entered into a credit agreement with a financial institution that provided for a one-year revolving credit facility in an amount of up to $10 million, subject to certain restrictions in the borrowing base based on eligibility of receivables. The credit agreement expired on June 30, 2003 and has not been renewed.

NOTE 6—COMMON STOCK:

The Company’s Amended and Restated Articles of Incorporation authorize the Company to issue 100,000,000 shares of common stock. At December 31, 2003 and 2002, there were 45,709,740 shares and 41,326,760 shares, respectively, of common stock issued and outstanding.

The Company has reserved the following number of shares of common stock for future issuance (in thousands):

	December 31,

	2003		2002		2001

Common stock warrants		1,229		3,329		25
Common stock under Employee Stock Purchase Plan		322		349		413
Common stock upon exercise of outstanding stock options		8,501		7,535		7,117

		10,052		11,213		7,555

On January 24, 2002, the Company completed a financing in which it raised $21 million in gross proceeds through a private placement of non-voting Series A Preferred Stock and warrants, at $30 per unit to a group of investors, which was convertible into 13,999,000 shares of common stock and warrants to purchase 3,303,760 shares of common stock. Each share of Series A Preferred Stock was convertible into 20 shares of Common Stock (or an effective Common Stock price of $1.50 per share). Investors also received warrants to purchase up to an additional 20 percent of shares of Series A Preferred Stock. The warrants have a term of three years and an exercise price equal to $39.00 per share (or an effective Common Stock exercise price of $1.95 per share).

At a Special Meeting of Stockholders held on March 7, 2002, the stockholders approved the issuance and sale of 699,950 shares of Series A Preferred Stock and warrants. As a result, the Preferred Stock and warrants automatically converted into 13,999,000 shares of common stock and warrants to purchase 3,303,760 shares of common stock.

As a result of the favorable conversion price of the preferred shares at the date of issuance, the Company recorded accretion of approximately $15 million (thus increasing the “net loss applicable to common stockholders” for the year ended December 31, 2002) relating to the beneficial conversion feature representing the difference between the accounting conversion price and the fair value of the common stock on the date of the transaction, after valuing the warrants issued in connection with the financing transaction. The Company valued the warrants using the Black-Scholes option pricing model, applying an expected life of three years, a weighted average risk-free rate of 3.61%, an expected dividend yield of zero percent, a volatility of 130% and a deemed fair value of common stock of $2.35, which was the value of the Company’s common stock on the date of grant.

Stock Repurchase Program

In August 2002, the Company’s Board of Directors approved a Stock Repurchase Program and authorized the repurchase of up to one million shares of the Company’s common stock in the open market over the next year. No shares were repurchased under the Stock Repurchase Program.

Common stock warrants

In connection with the financing that was completed on January 24, 2002, the Company issued warrants to purchase 3,303,760 shares of the Company’s common stock. This included unregistered warrants that were issued to the placement agent for the financing transaction to purchase 503,960 shares of the Company’s common stock. The 2,799,800 registered warrants have a term of three years and an effective Common Stock exercise price of $1.95 per share, whereas 419,968 of the 503,960 warrants issued to the placement agent have an effective Common Stock exercise price of $1.50 per share. The remainder of the warrants issued to the placement agent have an effective Common Stock exercise price of $1.95 per share.

During the year ended December 31, 2003, warrants were exercised which resulted in the issuance of 1,896,226 shares of the Company’s common stock with proceeds to the Company totaling approximately $3.1 million. These amounts included the exercise of warrants issued to the placement agent on a net issuance basis resulting in 300,438 shares of the Company’s common stock being issued to the placement agent.

The warrant agreement contained a provision for the mandatory exercise of the warrants if the Company’s common stock traded at $5.85 or higher for 20 out of 30 trading days. At the close of business on January 2, 2004 the Company’s common stock had traded at $5.85 or higher for 20 consecutive days and the Company was able to invoke the provision for the mandatory exercise of all outstanding warrants issued in connection with the January 2002 financing. All outstanding warrants were exercised in January 2004 resulting in the issuance of an additional 1.2 million shares of common stock. The Company received proceeds of approximately $2.3 million from the exercise of these warrants.

Restricted stock

In April 2003, the Company issued 1.8 million shares of restricted stock, pursuant to the 2000 Stock Plan. The Company determined the value of the restricted stock grant to be $324,000 by reference to the quoted market price at the time of issuance and is amortizing this amount over two years. Compensation expense related to the issuance of restricted stock was $108,000 for the year ended December 31, 2003.

NOTE 7—EMPLOYEE BENEFIT PLANS:

Stock Option Plans

In April 2000, the Company adopted the 2000 Stock Option Plan (the “2000 Plan”). Upon adoption of the 2000 Plan, shares reserved for issuance under the 1995 Stock Option Plan relating to ungranted options were cancelled, and outstanding options under the 1995 Plan became subject to the 2000 Plan. The 2000 Plan authorizes the Board of Directors to grant incentive stock options (“ISOs”) and nonstatutory stock options (“NSOs”) to employees, directors and consultants for up to 17,300,000 shares of common stock. ISOs may be granted only to employees of the Company (including officers and directors who are also employees). NSOs may be granted to employees, non-employee directors and consultants of the Company. No person will be eligible to receive more than 500,000 shares in any fiscal year pursuant to awards under the 2000 Plan other than a new employee of the Company who will be eligible to receive no more than 1,000,000 shares in the fiscal year in which such employee commences employment.

Under the 2000 Plan, ISOs and NSOs are granted at a price that is not to be less than 100% of the fair market value of the common stock on the date of grant, as determined by the Board of Directors. Initial hire-on stock options generally vest at 25% on the first anniversary date from the date of grant and then monthly thereafter over the remaining 36 months. Subsequent discretionary stock options, generally vest equally each month over 48 months. Options granted to shareholders who own more than 10% of the outstanding stock of the Company at the time of grant must be issued at prices not less than 110% of the estimated fair value of the stock on the date of grant. Options under the 2000 Plan may be granted for periods up to 10 years.

The following table summarizes stock option activity under the Company’s Stock Option Plans (in thousands, except per share data):

2000 Employee Stock Purchase Plan

In April 2000 the Company adopted the 2000 Employee Stock Purchase Plan (the “Purchase Plan”) under which 500,000 shares of common stock have been reserved for issuance. Eligible employees may elect to withhold up to 15% of their salary to purchase shares of the Company’s common stock at a price equal to 85% of the market value of the stock at the beginning or ending of a six month offering period, whichever is lower. No more than 5,000 shares may be purchased by an eligible employee during any calendar year. The Purchase Plan will terminate in 2010. Under the Purchase Plan, 27,184, 64,606 and 86,566 shares were issued during the years ended December 31, 2003, 2002 and 2001.

The Company did not recognize compensation expense related to employee purchase rights in 2003, 2002 or 2001.

401(k) Plan

The Company sponsors a 401(k) Plan (the “401(k) Plan”) which provides tax-deferred salary deductions for eligible employees. Employees may contribute up to 15% of their annual compensation to the 401(k) Plan, limited to a maximum annual amount as set periodically by the Internal Revenue Service. The 401(k) Plan permits, but does not require, the Company to make matching contributions. To date, no such matching contributions have been made.

NOTE 8—INCOME TAXES:

At December 31, 2003, the Company had net operating loss carryforwards for federal and state income tax purposes of approximately $106,000,000 and $35,000,000 respectively, which expire in varying amounts beginning in 2005 through 2021. In addition, the Company has credit carryforwards of approximately $5,200,000 for federal and state purposes. The federal and state carryforwards expire in varying amounts through 2021. Under the Tax Reform Act of 1986, the amounts of and benefits from net operating loss and tax credit carryforwards may be impaired or limited in certain circumstances. Events which could cause limitations in the use of net operating loss and tax credit carryforwards that the Company may utilize in any one year include, but are not limited to, a cumulative ownership change of more than 50%, as defined, over a three-year period.

Deferred taxes comprise the following (in thousands):

	December 31,

	2003			2002

Net operating loss carryforwards	$	38,108		$	36,533
Non-deductible reserves and accruals		2,433			2,163
Credit carryforwards		4,311			3,774
Capitalized research and development		2,849			2,089
Depreciation		226			185

Net deferred tax assets		47,927			44,744
Less: Valuation allowance		(47,927	)		(44,744	)

Net deferred tax assets		—			—

The Company believes that, based on number of factors, the available objective evidence creates sufficient uncertainty regarding the realizability of the deferred tax assets such that a full valuation allowance has been recorded. These factors include the Company’s history of losses, and relatively high expense levels, the fact that the market in which the Company competes is intensely competitive and characterized by rapidly changing technology, the lack of carryback capacity to realize deferred tax assets and the uncertainty regarding market acceptance of the Company’s products. The Company will continue to assess the realizability of the deferred tax assets based on actual and forecasted operating results.

NOTE 9—COMMITMENTS AND CONTINGENCIES:

Lease commitments

The Company leases office space and equipment under non-cancelable operating leases with various expiration dates through 2007. Rent expense for operating leases was as follows (in thousands):

	Year Ended December 31,

	2003		2002		2001

Rent expense	$	837	$	1,812	$	1,583

On July 18, 2002, the Company entered into a sublease agreement for the lease of new office space. Under the terms of the sublease agreement, commencing September 1, 2002 the Company became entitled to free rent until June 30, 2003. Subsequently, the Company will make monthly payments ranging from $0.65 per square foot to $1.35 per square foot until the sublease expires on March 31, 2007. As a result, the Company had $697,000 and $195,000 of deferred rent at December 31, 2003 and 2002, respectively. The Company’s lease for the old office space expired on November 30, 2002.

On November 30, 2003, the Company entered into a capital lease for test equipment. The lease has a term of 38 months and at the end of the lease the Company may purchase the test equipment for $1.00. The Company may also purchase the test equipment after 14 months for $166,000 or after 20 months for $133,000.

The value of the assets and related obligation recorded under the capital leases is $1,801,000 and $1,055,000 respectively at as of December 31, 2003 and $1,005,000 and $1,026,000 respectively at December 31, 2002.

Future minimum lease payments under non-cancelable operating leases and the capital lease are as follows (in thousands):

Long-term capital lease obligations			$	559

Inventory purchase commitments

At December 31, 2003 the Company had open purchase orders for the purchase of inventory totaling approximately $3.2 million. These purchase orders may only be cancelled if the foundry has not yet started production of the wafers to which the open purchase orders relate.

Contingencies

From time to time, in the normal course of business, various claims are made against the Company. In the opinion of the Company’s management, there are no pending claims, the outcome of which is expected to result in a material adverse effect on the financial position or results of operations of the Company. The Company is self insured for certain potential claims against the Company, directors or officers.

Guarantees

In November 2002, the FASB issued FIN No. 45 “Guarantor’s Accounting and Disclosure Requirements for Guarantees, including Indirect Guarantees of Indebtedness of Others — an interpretation of FASB Statements No. 5, 57 and 107 and rescission of FIN 34.” The following is a summary of the Company’s agreements that the Company has determined are within the scope of FIN 45.

The Company provides a limited warranty for up to one year for any defective products. During the years ended December 31, 2003 and December 31, 2002, warranty expense was insignificant. The Company has a reserve for warranty costs of $30,000, which has not changed in the past year.

On June 30, 2003, the Company entered into a Pledge and Security Agreement to provide collateral for outstanding standby letters of credit which totaled $0.7 million at December 31, 2003.

Pursuant to its bylaws, the Company has agreed to indemnify its officers and directors for certain events or occurrences arising as a result of the officer or director serving in such capacity. The term of the indemnification period is for the officer’s or director’s lifetime. To date, the Company has not incurred any costs as there have been no lawsuits or claims that would invoke these indemnification agreements. Accordingly, the Company has no liabilities recorded for these agreements as of December 31, 2003. The Company is self-insured for these and similar claims.

The Company enters into indemnification provisions under (i) its agreements with other companies in its ordinary course of business, typically with business partners, contractors and customers, its sublandlord and (ii) its agreements with investors. Under these provisions the Company has agreed to generally indemnify and hold harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of the Company’s activities or, in some cases, as a result of the indemnified party’s activities under the agreement. These indemnification provisions often include indemnifications relating to representations made by the Company with regard to intellectual property rights. These indemnification provisions generally survive termination of the underlying agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification provisions is unlimited. To date, the Company has not incurred any costs as there have been no lawsuits or claims related to these indemnification agreements. Accordingly, the Company has no liabilities recorded for these agreements as of December 31, 2003.

ITEM 9.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

On April 10, 2003, PricewaterhouseCoopers LLP, the independent accounting firm previously engaged as our auditing firm to audit our financial statements, resigned.

The reports of PricewaterhouseCoopers LLP on the financial statements for the fiscal years ending December 31, 2001 and 2002 contained no adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principle, except that the reports for each of the fiscal years ending December 31, 2001 and 2002 included an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern.

The decision by PricewaterhouseCoopers LLP to terminate the client-auditor relationship was not recommended or approved by the audit committee of our board of directors.

In connection with its audits for the fiscal years ending December 31, 2001 and 2002 and through April 10, 2003, there were no disagreements with PricewaterhouseCoopers LLP on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure which disagreements if not resolved to the satisfaction of PricewaterhouseCoopers LLP would have caused them to make reference thereto in their report on the financial statements for such years. In connection with the audit for the fiscal year ended December 31, 2002, our chief financial officer made certain public comments following the filing of Form 10-K/A on April 1, 2003 indicating management's disagreement with PricewaterhouseCoopers LLP including in its audit report on our financial statements for the year ended December 31, 2002 a reference to the existence of substantial doubt regarding our ability to continue as a going concern. The audit committee of our board of directors did not discuss the subject matter of this disagreement with PricewaterhouseCoopers LLP. We have authorized PricewaterhouseCoopers LLP to respond fully to the inquiries of its successor accountant concerning the subject matter of such disagreement.

PricewaterhouseCoopers LLP's letter to the Securities and Exchange Commission stating its agreement with the statements made in our Current Report on Form 8-K filed with the Securities and Exchange Commission on April 17, 2003, which are not materially different than the statements made herein, is filed as an exhibit to such Current Report on Form 8-K.

On May 9, 2003, we engaged the services of BDO Seidman, LLP as our new independent auditors for our fiscal year ended December 31, 2003. Our Board of Directors, with the recommendation of the Audit Committee of the Board of Directors, authorized and approved the engagement of BDO Seidman. In deciding to select BDO Seidman, the Audit Committee and our management considered auditor independence issues raised by commercial relationships we have or may have with certain accounting firms. With respect to BDO Seidman, we do not have any commercial relationship with BDO Seidman that would impair its independence. During our two most recent fiscal years ended December 31, 2002, and the subsequent interim period through May 9, 2003, we did not consult with BDO Seidman regarding any of the matters or events set forth in Item 304(a)(2)(i) and (ii) of Regulation S-K.

ITEM 9A.

CONTROLS AND PROCEDURES

Introduction. Rules promulgated under the Securities Exchange Act of 1934, as amended, (the “Act”) define “disclosure controls and procedures” to mean controls and procedures that are designed to ensure that information required to be disclosed by public reporting companies in the reports filed or submitted under the Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms (“Disclosure Controls”). New rules promulgated under the Act define “internal control over financial reporting” to mean a process designed by, or under the supervision of, a public company’s principal executive and principal financial officers, or persons performing similar functions, and effected by such company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles (“GAAP”), including those policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements (“Internal Controls”).

We have designed our Disclosure Controls and Internal Controls to provide reasonable assurances that their objectives will be met. A control system, no matter how well designed and operated, can provide only reasonable, but not absolute, assurance that its objectives will be met. All control systems are subject to inherent limitations, such as resource constraints, the possibility of human error and the possibility of intentional circumvention of these controls. Furthermore, the design of any control system is based in part upon assumptions about the likelihood of future events, which assumptions may ultimately prove to be incorrect. As a result, we cannot assure you that our control system will detect every error or instance of fraudulent conduct.

Evaluation of disclosure controls and procedures. Based on their evaluation as of December 31, 2003, our chief executive officer and chief financial officer, with the participation of management, have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934) were effective, at the level of reasonable assurance, to ensure that the information required to be disclosed by us in this annual report on Form 10-K was recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and Form 10-K.

Changes in internal controls.There were no changes in our internal controls over financial reporting during the quarter ended December 31, 2003, that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
