respect to any changes in non-employee director compensation levels to our Board. In 2024, Aon, our Compensation Committee’s independent compensation consultant reviewed the market competitiveness of our non-employee director compensation policy relative to our compensation peer group and recommended certain changes based on governance best practices and market trends to ensure we can attract and retain a highly qualified board of directors.
