Laporan Bulanan Registrasi Pemegang Efek
Regulatory Filings Classification · 65% confidence The document is titled “Laporan Bulanan Registrasi Pemegang Efek” (“Monthly Report of Securities Holders Registration”) submitted to the Indonesian exchange. It contains detailed tables of shareholder register data, free‐float calculations, and investor classifications for the month ending April 2026. It is a routine compliance filing with no financial statements, earnings highlights, or management discussion.

Annual Report Classification · 95% confidence The document contains extensive financial data fields with multiple periods and dates, including start and end dates for fiscal years and quarters, and detailed equity and capital account items. The presence of multiple years and detailed financial metrics suggests this is a comprehensive financial report rather than a brief announcement or certification. The document length is 15,000 characters, which is substantial and consistent with a full financial report. The data appears to cover full fiscal years (e.g., 2019-01-01 to 2019-12-31, 2020-01-01 to 2020-12-31) and includes detailed equity components, which are typical of an Annual Report. There is no indication that this is a certification, announcement, or a short summary. Therefore, the document is best classified as an Annual Report (10-K). 9M 2011
