Regulatory Filings Classification · 95% confidence The document is a revenue summary report from a listed company (台勝科) showing monthly and cumulative net operating revenue figures for December of the 105th year of the Republic of China calendar (equivalent to 2016). It includes percentage changes compared to the previous year and notes on accounting standards (IFRS) application. The document is short (776 characters) and primarily provides summarized financial data without detailed financial statements or management discussion. It does not appear to be a full annual or interim report, nor an earnings release or investor presentation. It is a regulatory disclosure of summarized financial data, typical of a Regulatory Filing (RNS) category, as it does not meet the threshold for a full financial report and is not an announcement of a report publication. Therefore, the best classification is Regulatory Filings (RNS).

105年11月董事會成員及持股
Director's Dealing Classification · 95% confidence The document contains detailed tables listing shareholdings and pledged shares of company insiders, including directors, supervisors, and senior management. It provides specific data on share counts held by various insiders and their related parties. The content focuses on insider shareholdings and related disclosures rather than financial results, management changes, or meeting materials. This type of document aligns with insider share transactions or holdings disclosures. Given the nature of the data, it fits best under the category of Director's Dealing (DIRS), which covers reports of personal share transactions by company directors and executives. The document length is about 3,080 characters, which is consistent with a detailed insider shareholding report rather than a full financial report or announcement. Therefore, the classification is DIRS with high confidence.

105年11月背書保證與資金貸與
Regulatory Filings Classification · 95% confidence The document is a brief financial disclosure from a listed company (台勝科) providing information about fund loans and endorsement guarantees for a specific month (November of the 105th year in the Republic of China calendar, which corresponds to 2016). The content is tabular and concise, focusing on specific financial data points without detailed analysis or narrative. The length is only 620 characters, indicating it is a short regulatory disclosure rather than a full report. There is no indication of it being an annual or interim report, audit report, or any other detailed filing. It fits best as a Regulatory Filing (RNS), which is the fallback category for miscellaneous regulatory disclosures that do not fit other specific categories.

105年11月營業收入
Regulatory Filings Classification · 90% confidence The document is a revenue summary report from a listed company (台勝科) showing monthly and cumulative net operating revenue figures for a specific month (November of 民國105年, which corresponds to 2016). It includes comparative figures from the previous year and percentage changes. The document is short (774 characters) and contains financial data but is not a comprehensive financial report like an annual or interim report. It appears to be a regulatory filing of summarized financial data, likely a routine disclosure of monthly revenue figures to a regulatory body. There is no indication that this is a full financial report, audit, earnings release, or management discussion. It fits best under Regulatory Filings (RNS) as a general regulatory announcement of financial data that does not fit other specific categories.

105年第3季財務報告書 — 201604_3532_AIA.pdf
Annual Report Classification · 99% confidence The document is titled 'Consolidated Financial Statements for the Years Ended December 31, 2016 and 2015 and Independent Auditors’ Report' for Formosa Sumco Technology Corporation and Subsidiaries. It contains detailed consolidated financial statements including balance sheets, statements of comprehensive income, changes in equity, cash flows, and notes to the financial statements. It also includes an Independent Auditors' Report with an opinion on the consolidated financial statements, audit basis, key audit matters, and responsibilities of management and auditors. The document is comprehensive, covers a full fiscal year, and includes full financial data and analysis. This matches the definition of an Annual Report (10-K) filing, which is an official yearly report covering company activity and full financial performance. There is no indication that this is merely an announcement or certification, so it is not RPA or RNS. Therefore, the correct classification is 10-K with high confidence.
