確認書
Regulatory Filings Classification · 1% confidence The document is titled '確認書' (Confirmation Letter) and explicitly references the Financial Instruments and Exchange Act. It serves as an officer certification regarding the accuracy of a semi-annual report. According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations should be classified as Regulatory Filings (RNS), even if they reference a specific report type like an interim report.

Interim / Quarterly Report Classification · 1% confidence The document is a '半期報告書' (Semi-annual Report) for the company '株式会社土木管理総合試験所' covering the period from January 1, 2025, to June 30, 2025.

臨時報告書
AGM Information Classification · 1% confidence The document is titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and is submitted to the Kanto Local Finance Bureau Director on March 24, 2025. Section 1 explicitly states the reason for filing: decisions were made at the Annual General Meeting (AGM) held on March 21, 2025, and the report is submitted based on Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act. Section 2 details the resolutions passed, including the approval of the dividend (剰余金の処分の件) and the election of 10 directors (取締役10名選任の件), along with the voting results. This structure—a formal report detailing the outcomes of a shareholder meeting (AGM) resolutions—is characteristic of a filing announcing the results of a general meeting. While it relates to the AGM, the specific content is the official voting results and decisions, which aligns best with the Declaration of Voting Results & Voting Rights Announcements (DVA). It is not the AGM presentation (AGM-R) or a proxy solicitation (PSI).

内部統制報告書－第40期(2024/01/01－2024/12/31)
Governance Information Classification · 1% confidence The document is explicitly titled "内部統制報告書" (Internal Control Report) in the header table. It references the legal basis as Article 24-4-4, Paragraph 1 of the Financial Instruments and Exchange Act (金融商品取引法第24条の４の４第１項), which mandates the filing of an internal control report by listed companies in Japan. The content discusses the framework, scope, criteria, and conclusion regarding the effectiveness of internal controls over financial reporting. This directly corresponds to the requirements for an Audit Report/Information filing, specifically concerning internal controls, which aligns best with the 'AR' (Audit Report / Information) category, as it is a formal report on internal control effectiveness, distinct from a full annual report (10-K) or a simple earnings release (ER).
