Pay vs Performance Disclosure

Non-GAAP Measure Description

We determined adjusted pre-tax pre-provision income ("Adjusted PTPP") to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs in 2023. Adjusted PTPP is a non-GAAP measure, and is defined as pre-tax income plus provision for credit losses, restructuring charges and incremental expense related to the FDIC assessment rate change. This performance measure may not have been the most important financial performance measure for years 2022, 2021 and 2020 and we may determine a different financial performance measure to be the most important financial performance measure in future years.
