regarding the Impact on the Company's Financial and Business Status
from the Earthquake occurring on March 4th, 2010
The earthquake recorded on March 4th,
2010 did not impact the company's Hsinchu fabs and office areas.
Buildings, facilities and equipment in Fab12A in Southern Taiwan
Science Park were also unaffected, although some production lines
in Fab12A were halted due to the shutdown of certain equipment.
UMC conducted maintenance and examination immediately following
the incident. The estimated production days affected on the company
in total will be approximately 1~1.5 days. The company will adjust
manufacturing upward at Fab12i in Singapore and close any production
gap once Fab12A resumes full production in order to minimize the
approximately 1~1.5 days accumulated production impact.
