Mr. Max Cheng, CFO of AUO commented "the second quarter results exceeded our guidance announced during our first quarter 2005 investor conference, primarily contributed by product mix change and stabilizing panel prices seen in certain applications. In addition, the smooth ramp-up progress for AUO's 6th generation fab also contributed to the successful execution of AUO's LCD TV business strategy and production allocation plan, and provided us an opportune timing to expand our larger size LCD TV panel business. Through effective cost control and enhanced operational efficiency, AUO was able to achieve a gross margin of 6.8% for second quarter of 2005, an improvement from the 3.2% gross margin of the first quarter 2005. In addition, our inventory continues to improve with inventory days declining again from the 38 days as of March 31, 2005 to 32 days on a consolidated basis as of June 30, 2005.

Dr. Hui Hsiung, Executive Vice President of AUO added. "AUO's new sixth-generation fab ("G6", 1,500mm x 1,850mm) that commenced ramp-up process in March 2005 is well on track. The new capacity contributed from ongoing ramp-up of the G6 fab supported the increase in our 32" LCD TV panel shipment in the second quarter 2005. We are targeting to ramp up its monthly substrate input capacity to 60,000 substrates by end of this year, from 25,000 substrates at end of June 2005. We expect the ramp-up of our 6G fab to be well-timed to capture the emerging demand for LCD TV, especially from the fast growing 32" and 37" LCD TV markets.
