Other Commitments

Like other manufacturers, the Company is subject to a broad range of federal, state, local and foreign laws and requirements, including those concerning air emissions, discharges into waterways, and the generation, handling, storage, transportation, treatment and disposal of hazardous substances and waste materials, as well as the remediation of contamination associated with releases of hazardous substances at the Company’s facilities and off-site disposal locations, workplace safety and equal employment opportunities. These laws and regulations are constantly changing, and it is impossible to predict with accuracy the effect that changes to such laws and regulations may have on the Company in the future. Like other industrial concerns, the Company’s manufacturing operations entail the risk of noncompliance, and there can be no assurance that the Company will not incur material costs or other liabilities as a result thereof.
