The percentage of revenue from the communication segment decreased to 57% of total revenue in 1Q09 due to decreasing demand for communication chips, especially in wireline products.
Note 3: Revenue in this section represents wafer sales.
Blended Average Selling Price Trend
The blended average selling price (ASP) decreased by 10% in US dollar terms during 1Q09, due to a larger portion of the process technology mix coming from older process generations as well as short-term volume discounts to customers.

Wafer shipments dropped 32.3% sequentially to 384 thousand, a decrease from 567 thousand 8-inch equivalent wafers in the previous quarter. Overall utilization rate for the quarter was 30%.
Note 4: Utilization Rate = Quarterly Wafer Out / Quarterly Capacity
Capacity (5)
Capacity for 1Q09 was 1,151 thousand 8-inch equivalent wafers. The total capacity remained the same as from Q408. The total estimated installed capacity in 2Q09 also remains unchanged, although 65nm capacity is increasing due to internal capacity conversion and 8-inch wafer capacity moving to more advanced nodes.
