소속부변경
Regulatory Filings Classification · 95% confidence The document is a brief announcement about a change in the company's classification or department affiliation (소속부변경) from '우량기업부' to '중견기업부' with an effective date. It does not contain financial data, management information, or detailed reports. It is a regulatory announcement about an internal classification change. This fits best under Regulatory Filings (RNS) as it is a general regulatory announcement that does not fit other specific categories.

[기재정정]타인에대한채무보증결정
Capital/Financing Update Classification · 82% confidence The document is a formal corporate disclosure of a board resolution to extend and issue guarantees on behalf of an overseas affiliate (“타인에 대한 채무보증 결정”), detailing amounts, periods, related parties, and board approval. This is a financing-related transaction announcement rather than a full financial report or regulatory notice.
