Environmental liabilities could force us to expend significant capital and incur substantial costs.
Federal, state and local regulations impose various environmental controls on the storage, use, discharge and disposal of certain chemicals and gases used in semiconductor processing. Our facilities have been designed to comply with these regulations, and we believe that our activities conform to present environmental regulations. Increasing public attention has, however, been focused on the environmental impact of electronics manufacturing operations. While we to date have not experienced any materially adverse business effects from environmental regulations, there can be no assurance that changes in such regulations will not require us to acquire costly remediation equipment or to incur substantial expenses to comply with such regulations. Any failure by us to control the storage, use or disposal of, or adequately restrict the discharge of hazardous substances could subject us to significant liabilities.
