기업가치제고계획(자율공시)
Regulatory Filings Classification · 1% confidence The document is a 'Corporate Value Enhancement Plan' (기업가치 제고 계획) filed by DI Corp. It outlines the company's future strategy regarding shareholder returns, dividend policies, and investor communication. In the context of Korean regulatory filings (KRX), these voluntary disclosures regarding corporate value enhancement do not fit into standard financial reporting categories like 10-K or IR. Since it is a specific regulatory disclosure regarding corporate strategy and governance, 'RNS' (Regulatory Filings) is the most appropriate fallback category.

Audit Report / Information Classification · 1% confidence The document is a formal announcement titled '감사보고서 제출' (Submission of Audit Report) filed with the Korean Exchange (KRX).
