“Deposits (SOD)” are deposits as reported to the FDIC at branch level in the Summary of Deposits (SOD), June 30, 2025, and are nominal. They reflect where deposits are booked and may differ from the institution’s balance-sheet total. “County’s % of Bank’s Deposits” is this county’s share of the institution’s total SOD deposits; “Bank’s % of County Deposits” is this institution’s deposits as a percent of all deposits booked in that county. Counties within a Combined or Metropolitan Statistical Area link to their full profile; other counties are shown for completeness.
