³ Utilization Rate = Quarterly Wafer Out / Quarterly Capacity

Capacity⁴ for Foundry Segment

Total capacity in the fourth quarter totaled 1,958K 8-inch equivalent wafers. We expect first quarter capacity to decline by approximately 1.1% QoQ to 1,937K 8-inch equivalent wafers, primarily due to fewer working days and tool maintenance.
