Its security type is Corporate, its sector is 2911 Petroleum Refining, and its jurisdiction is United States, Delaware. Segment is not on the record. Status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 81 filings in the twelve months to 2026-11-08, across 46 filing days. The median gap between filing days is 3 days. The latest filing is dated 2026-11-03, 5 days before the record date, and is of type results. The NYSE median cadence gap is 6.0 days across 3256 issuers, and the NYSE median latency is 4.0 days. The 2911 Petroleum Refining sector median cadence gap is 5.5 days across 18 issuers, and the sector median latency is 3.0 days.\n\n## Auditor\n\nThe auditor is not on the record, because the latest annual report cover carries no dei:AuditorName tag. The auditor 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. Domicile change is not on the record, because EDGAR states no dated change of state of incorporation on a filing line. Segment move is not on the record, because the exchanges' tier transfers are not EDGAR filings. The halt flag reads listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable under rule version acm-68000/us/reasonable-basis-suitability-finra-rule-2111/r1, as of 2026-11-04. The chapter's orderability section carries no client_categories, so the outcome cannot name its client category.\n\n## Coverage\n\nNo research houses were found on the issuer's investor-relations page.\n\n## Open research\n\nNo openly published research notes were found on the record.\n\n## Licensed\n\nLicensed research: none loaded. A licensed row is served only to an agent whose firm holds that licence (licensor, entitlement). No licensed row is loaded.\n\n## As-of depth\n\nThe vintage is sealed. Sealed years that hold the issuer are 2021, 2022, 2023, 2024, 2025 and 2026. The market's earliest sealed date is 2021-01-04. The live record began on 2026-09-12.\n\n## Sources\n\n8 source pages are named on this page; every value above carries its own source page and read date in the numbers.\n\n- https://www.sec.gov/files/company_tickers_exchange.json (identity.exchange)\n- https://www.sec.gov/data-research/sec-markets-data/fails-deliver-data (identity.isin)\n- https://data.sec.gov/submissions/CIK0001510295.json (identity.jurisdiction)\n- https://mapping.gleif.org/api/v2/isin-lei/latest/download (identity.lei)\n- https://mcp.us-cm-kg.ai/events/NYSE/MPC (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://mcp.us-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.us-cm-kg.ai/record/NYSE/MPC (the record)\n",
