 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# NUVEEN SELECT TAX FREE INCOME PORTFOLIO (NYSE: NXP) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is NUVEEN SELECT TAX FREE INCOME PORTFOLIO, listed on the NYSE under ticker NXP. Its ISIN is US67062F1003 and its LEI is 5493005XMO16VD219F88. Its security type is non-operating entity type (other). Its segment, sector and jurisdiction are not on the record. Its status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 24 filings on 20 filing days in the window 2025-11-08 to 2026-11-08. By type, the record holds 1 agm_egm filing, 6 directors_dealings filings, 2 prospectus filings and 15 regulatory_filing filings. The median gap between filing days is 10 days. The latest filing is dated 2026-10-27 and is of type directors_dealings, 12 days before the record date. The NYSE median cadence gap is 6.0 days across 3256 issuers, with a median of 64.0 filings and a median latency of 4.0 days. The sector median is not on the record for this market.\n\n## Auditor\n\nThe auditor is not on the record, because the latest annual report cover carries no dei:AuditorName tag, as foreign private issuers and older filings carry none. 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, because EDGAR states no dated change of state of incorporation on a filing line. The 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 chapter date 2026-11-04. The chapter's orderability section carries no client_categories, so the outcome cannot name its client category.\n\n## Coverage\n\nThe field has been read and no research houses were found on the issuer's investor-relations page. The count is 0.\n\n## Open research\n\nThe field has been read and no openly published research notes were found. The count is 0.\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 issuer's sealed years are 2021, 2022, 2023, 2024, 2025 and 2026. The market's vintage is sealed, with earliest sealed date 2021-01-04. The live record began 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://mapping.gleif.org/api/v2/isin-lei/latest/download (identity.lei)\n- https://data.sec.gov/submissions/CIK0000883618.json (identity.name)\n- https://mcp.us-cm-kg.ai/events/NYSE/NXP (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/NXP (the record)\n",
