Its security type is Corporate. Its segment is not on the record. Its sector is 6022 State Commercial Banks, and its jurisdiction is United States, Michigan. Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 112 filings in the window 2025-11-08 to 2026-11-08, across 55 filing days. The median gap between filing days is 6.0 days, and the latest filing is dated 2026-11-02, 6 days before the record date. The latest filing is of type takeover.

The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds no listing, delisting or name change events.

The segment move is not on the record, as the exchanges' tier transfers are not EDGAR filings. The halt flag reads listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable. The chapter's orderability section carries no client categories, so the outcome cannot name its client category. The rule version is acm-68000/us/reasonable-basis-suitability-finra-rule-2111/r1, and the chapter is as of 2026-11-04.\n\n## Coverage\n\nNo research houses were found on the issuer's investor-relations pages read.\n\n## Open research\n\nNo openly published research notes were found on the record.\n\n## Licensed\n\nLicensed research: none loaded.
