内部統制報告書－第27期(2022/10/01－2023/09/30)
Governance Information Classification · 100% confidence The document is titled "内部統制報告書" (Internal Control Report) and explicitly states its basis under the Financial Instruments and Exchange Act (金融商品取引法第24条の４の４第１項). It details the scope, criteria (based on the framework established by the Financial Accounting Standards Board), measurement date (2023年９月30日), and the conclusion that internal controls over financial reporting are effective as of that date. This content perfectly matches the description of an Audit Report / Information filing, which covers internal or regulatory stress tests and applied accounting principles, distinct from the full Annual Report (10-K). In the provided schema, 'AR' (Audit Report / Information) is the most appropriate classification for a formal Internal Control Report in Japan, as it deals with the assurance and structure of financial reporting controls.

臨時報告書
AGM Information Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report) and explicitly states in Section 1 that it is being submitted because resolutions were passed at the company's Annual General Meeting (定時株主総会) held on December 20, 2023, in accordance with Japanese financial regulations (金融商品取引法第24条の５第４項). Section 2 details the resolutions, which include dividend approval, amendments to the articles of incorporation (transitioning to an Audit and Supervisory Committee structure), and the election/remuneration of directors and audit committee members. This content—reporting the results of a shareholder meeting—is characteristic of an AGM Result announcement. Since the provided options include 'AGM Information (Code: AGM-R)' for presentations and materials shared during the AGM, and 'Declaration of Voting Results & Voting Rights Announcements (Code: DVA)' for official results from shareholder votes, DVA is the most precise fit for reporting the voting outcomes of the resolutions passed at the meeting. The document is a formal report of voting results.

確認書
Report Publication Announcement Classification · 100% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under Article 24-4-8 of the Financial Instruments and Exchange Act of Japan. This is a mandatory regulatory filing that accompanies a Quarterly Report (Shihanki Hokokusho) to certify the accuracy of the financial statements. Since it is a specific regulatory filing required by law to accompany the quarterly report, and it does not fit into the 'Interim/Quarterly Report' category itself (which would be the report body), it is best classified as a Regulatory Filing (RNS).

四半期報告書－第27期第3四半期(2023/04/01－2023/06/30)
Interim / Quarterly Report Classification · 100% confidence The document is a '第３四半期報告書' (Third Quarter Report) for the company '株式会社ディ・アイ・システム' (D.I.System Co., Ltd.). It contains detailed financial statements, including the balance sheet, income statement, and comprehensive income statement for the third quarter period ending June 30, 2023. It also includes management analysis (MDA) and notes to the financial statements. As it is a comprehensive quarterly financial report containing actual financial data, it is classified as an Interim/Quarterly Report (IR). 9M 2023

Report Publication Announcement Classification · 100% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under Article 24-4-8 of the Financial Instruments and Exchange Act of Japan. This is a mandatory regulatory filing that accompanies a Quarterly Report (Interim Report) to confirm the accuracy of the financial statements. Since it is a formal regulatory filing required by law to accompany the financial reporting process and does not constitute the full financial report itself, it falls under the category of Regulatory Filings.
