In 2022, we continued to emphasize a culture of high performance, and our talent and rewards strategies centered on incentive programs that provided rewards based on meaningful demonstrations of business achievements and individual performance contributions to the Company. The Compensation and People Committee has designed the compensation program for our named executive officers to reflect the importance placed on Company and business achievement in a high-performing culture. To that end, our core compensation program is closely aligned with Company performance and consists of base salary, an annual cash incentive, and long-term equity incentives based on both performance and service over a 3-year Please refer to the Compensation Discussion and Analysis section of this proxy statement for details regarding how the Compensation and People Committee links the compensation paid to our named executive officers to our corporate performance.
