"In the third quarter of 2010, the panel industry witnessed inventory
adjustments by the customers and the lower-than-expected panel prices.
However, thanks to the dual strategy for product value optimization and
product portfolio adjustments, our average selling price per square meter
dropped by merely 6.5% from the previous quarter, " said Mr. Andy Yang, Chief
Financial Officer of AUO. "As such, our company is able to remain operating
margin positive for this quarter, and continue to sustain comparative
advantage in terms of EBITDA margin. On the other hand, we also proactively
adjusted our capacity utilization rates, so that our inventory turnover days
improved from 43 days last quarter to 40 days at the end of the third
quarter."

Looking into the fourth quarter, AUO will continuously adjust its
capacity utilization rates based on market demands. We hope to continuously
provide high value-added products and innovative R&D and technology. Through
these efforts, we hope to enhance our capacity values, strengthen the
long-term customer relations, and achieve better synergies in the alliances
with customers.
