Key Financial Metrics (Year Ended Dec 31, 2009)

Material Changes vs. Prior Period

• Revenue Growth: Revenue increased 2.8% to $165.0 million, driven primarily by an $8.2 million increase in DC to DC converter sales. This was partially offset by a $4.5 million decline in lighting control products due to the market shift from CCFL to WLED backlighting.
• Margin Compression: Gross margin declined from 61.9% to 59.2% due to price pressure, declining average selling prices, and increased inventory reserves for lighting control products.
• Profitability: Net income decreased 18.8% to $19.7 million. This decline was influenced by higher litigation expenses ($9.5 million vs. $6.7 million in 2008) and lower interest income, despite a $6.4 million benefit from the reversal of a patent litigation provision.
• Liquidity: Working capital increased significantly to $179.6 million, largely due to the reclassification of $16.9 million in auction-rate securities to short-term investments and proceeds from stock issuances.

Guidance, Outlook, Risks, and Unusual Items

• Unusual Items: The company recorded a $6.4 million net benefit from the reversal of a patent litigation provision related to a settled lawsuit with Taiwan Sumida Electronics (TSE), which also resulted in the retrieval of a $7.4 million escrow deposit.
• Litigation Risks: Significant ongoing legal proceedings with O2Micro regarding patent infringement of CCFL backlight inverter products. The company cannot estimate the probability of loss or range of damages. Litigation expenses are difficult to forecast and may vary substantially.
• Investment Liquidity: The company holds $35.6 million (net of impairment) in government-backed student loan auction-rate securities. $37.4 million of these securities have failed to reset through auctions since 2008. While the company has a put right to sell $16.9 million of these to UBS at par commencing June 2010, the liquidity of the remaining portfolio is uncertain.
• Outlook: Management expects operating results to fluctuate due to the cyclical nature of the semiconductor industry, legal proceedings, and macro-economic conditions. No specific numerical guidance for 2010 was provided in the text.

Investor Verification Checklist

• Litigation Status: Monitor developments in the O2Micro patent infringement cases (ITC and Northern District of California), as an adverse outcome could severely impact revenue and require significant damages.
• Auction-Rate Securities: Verify the status of the $37.4 million illiquid investment portfolio and the execution of the UBS put right in June 2010.
• Product Mix Transition: Assess the pace of the market shift from CCFL to WLED backlighting and its impact on the lighting control product line revenue.
• Customer Concentration: Review the top three customers, which accounted for 34% of total revenue in 2009.
• Inventory Levels: Evaluate inventory reserves given the history of write-downs related to lighting control products and potential demand fluctuations.
