Blended Average Selling Price Trend
The blended average selling price (ASP) increased during 4Q11 was mainly due to increasing revenue contribution from 40nm and 65nm.

Wafer shipments decreased 10.7% sequentially to 915K in 4Q11, compared to 1,025K 8-inch equivalent wafers shipped in 3Q11. Since wafer shipments decrease and wafer capacity increased in Q4, overall utilization rate for the quarter dropped to 68%.
Note 4: | Utilization Rate = Quarterly Wafer Out / Quarterly Capacity | |
Capacity (Note 5)
Capacity during the fourth quarter was 1,376K 8-inch equivalent wafers. The increase in total capacity is mainly due to advanced capacity expansion at 12" fabs. The estimated installed capacity in 1Q12 will decrease to 1,364K 8-inch equivalent wafers mainly due to fewer working days.
