公告本公司名稱由「光磊科技股份有限公司」更名 為「台亞半導體股份有限公司」，公告期間：110年11月04日 至 111年02月03日
Regulatory Filings Classification · 95% confidence The document is a regulatory announcement from a listed company (stock code 2340) about a change in the company name from '光磊科技股份有限公司' to '台亞半導體股份有限公司'. It includes details such as the date of the name change approval, shareholder meeting resolution date, and related regulatory references. There is no financial data, no report attached or referenced, and the document is short (853 characters). This is a corporate announcement about a company name change, which does not fit into financial reports or other specific categories like management changes or capital changes. Therefore, it best fits the category of Regulatory Filings (RNS), which is the fallback for miscellaneous regulatory announcements that do not fit other categories.

Audit Report / Information Classification · 95% confidence The document is titled 'CONSOLIDATED FINANCIAL STATEMENTS AND INDEPENDENT AUDITORS’ REPORT' for the years ended December 31, 2021 and 2020. It contains detailed auditor's opinion, basis for opinion, key audit matters, responsibilities of management and auditors, and references to accounting standards and regulations. The content includes comprehensive financial statements and audit results, not just an announcement or summary. The length is substantial (15,000 characters), indicating a full report rather than a brief notice. Therefore, this document fits the definition of an Audit Report / Information (AR), which includes standalone audit reports and applied accounting principles, excluding full annual reports. It is not an Annual Report (10-K) because it lacks broader company activity and management discussion sections typical of annual reports. It is not a Regulatory Filing (RNS) or Report Publication Announcement (RPA) because it contains the full audit report and financial statements, not just a notice or certification. FY 2021
