発行登録書（株券､社債券等）
Capital/Financing Update Classification · 95% confidence The document is a 'Shelf Registration Statement' (発行登録書) filed with the Kanto Local Finance Bureau by Daido Steel Co., Ltd. This document is a regulatory filing used to register securities (bonds) for future issuance over a specified period. It does not fit into specific categories like earnings releases or annual reports, and it is a formal regulatory document rather than a simple announcement. Therefore, it falls under the 'Regulatory Filings' category.

確認書
Regulatory Filings Classification · 100% confidence The document is titled '確認書' (Confirmation Letter) and explicitly references '金融商品取引法第24条の５の２第１項' (Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act). It serves as an officer certification confirming the accuracy of a semi-annual report. According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations, even if they reference a report (like a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself.
