Role of the Compensation Committee and Management

Our executive compensation program is determined and approved by the Compensation Committee. During 2023, the Compensation Committee was responsible for the oversight, implementation and administration of all our executive compensation plans and programs. None of the named executive officers had any role in approving the compensation of the other named executive officers. However, the Compensation Committee does consider the recommendations of our Chief Executive Officer in setting compensation levels for our named executive officers other than himself. The Compensation Committee solely determined the compensation of our Chief Executive Officer.

On an annual basis, the Compensation Committee reviews compensation for our named executive officers in conjunction with performance evaluations, salary increase recommendations, determination of bonus pay outs and deliberations regarding long-term incentive grants. The Compensation Committee has conducted, and plans to continue to conduct, annual reviews of our executive compensation program to ensure its continued alignment with our compensation philosophy. The Compensation Committee will continue to make decisions taking into account good governance practices regarding compensation, including reliance on market data for the chemical and specialty chemical industries, and all other considerations described in this Compensation Discussion and Analysis.
