The LEI is not on the record, as no GLEIF record is registered under 114-81-33003. The security type is Corporate, the segment is not on the record, the sector is 건물설비 설치 공사업, and the jurisdiction is South Korea as a DART filer with a corporate registration number. The issuer is listed and not halted.\n\n## The disclosure read\n\nThe record holds 82 filings in the window 2025-11-06 to 2026-11-06, across 53 filing days. The median gap between filing days is 6.0 days. The median latency for the exchange peers is 7.0 days, and the issuer's latest filing, dated 2026-10-28, was 9 days before the record date of 2026-11-06. The latest filing is a corporate_news filing. The sector node holds 2 issuers, which is fewer than five, so no sector median is stated.\n\n## Auditor\n\nThe auditor of record is 삼정회계법인, with its location not on the record. Auditor changes are not on the record, as this register has no lifecycle type map yet.\n\n## Events and halts\n\nListing, delisting, name change, domicile change and segment move are not on the record, as this register has no lifecycle type map yet. The halt flag shows the issuer listed and not halted.\n\n## Orderability\n\nThe outcome is not determinable, because the chapter's orderability section carries no client_categories and so the outcome cannot name its client category. The rule version is acm-68000/kr/suitability-and-appropriateness-fscma-articles-46-and-46-2/r1, with the chapter as of 2026-11-04.\n\n## Coverage\n\nNo research house was found on the investor-relations pages read, and the count is 0.\n\n## Open research\n\nNo openly published research notes were found, and 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 vintage is not sealed. The live record began on 2026-09-12. Years are sealed in the store for 2021 through 2026 but are not served as of a date, and the as-of door answers not_sealed.\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://kind.krx.co.kr/corpgeneral/corpList.do?method=download&searchType=13 (identity.exchange)\n- https://data.krx.co.kr/comm/bldAttendant/getJsonData.cmd (identity.isin)\n- https://opendart.fss.or.kr/api/company.json?corp_code=00143262 (identity.jurisdiction)\n- https://mcp.kr-cm-kg.ai/events/KOSPI/010400 (the disclosure lines)\n- https://kind.krx.co.kr/investwarn/tradinghaltissue.do?method=searchTradingHaltIssueMain (the halt flag)\n- https://dart.fss.or.kr/dsaf001/main.do?rcpNo=20260323000971 (the auditor)\n- https://mcp.kr-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.kr-cm-kg.ai/record/KOSPI/010400 (the record)\n",
