Advanced Semiconductor Engineering (ASE) saw sales of its ATM (assembly test and material) division decrease 4.2% sequentially to NT$32.6 billion (US$1.1 billion) in the fourth quarter of 2010, falling to meet its flat growth estimate. The company attributed the drop to changes in currency exchange rates.

ASE's ATM business posted revenues of NT$10.69 billion in December, down 0.4% on month. On an annual basis, revenues for December and the fourth quarter showed growth of 22.9% and 24%, respectively.

ASE's consolidated revenues for the fourth quarter grew 3.5% on quarter to NT$53.28 billion. Driven by land property sales, ASE's consolidated sales climbed 16.2% on month to NT$19.55 billion in December.

ASE said it generated an income of NT$3.48 billion through land sales in Shanghai.

Fellow packaging company Siliconware Precision Industries (SPIL) earlier announced consolidated revenues were NT$15.48 billion in the fourth quarter of 2010, down 5.1% sequentially.
