(NYSE: THG) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is HANOVER INSURANCE GROUP, INC., listed on the NYSE under ticker THG, with ISIN US4108671052 and LEI JJYR6MFKFF6CF8DBZ078. Its security type is Corporate, its sector is 6331 Fire, Marine & Casualty Insurance, and its jurisdiction is United States — Delaware. Its segment is not on the record. Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 141 filings in the twelve months to 2026-11-08, on 54 filing days. The median gap between filing days is 3 days, and the latest filing was made 3 days before the record date. The latest filing is dated 2026-11-05 and is of type directors_dealings.

The sector median gap is 5.0 days, with a median of 80 filings and a median latency of 3 days across 85 issuers.\n\n## Auditor\n\nThe auditor is not on the record, as the latest annual report cover carries no dei:AuditorName tag. The auditor's location is not on the record. The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds no listing, delisting or name change lines. The domicile change is not on the record, as EDGAR states no dated change of state of incorporation on a filing line. The segment move is not on the record, as the exchanges' tier transfers are not EDGAR filings. The issuer is listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable, as the chapter's orderability section carries no client categories and so the outcome cannot name its client category.
