105年第3季綜合損益表
Interim / Quarterly Report Classification · 95% confidence The document contains a consolidated comprehensive income statement with detailed financial data for the third quarter of the 105th year (Taiwan calendar, corresponding to 2016) and year-to-date figures. It includes revenue, costs, operating profit, net profit, and earnings per share, indicating substantive financial data and analysis for a period shorter than a full fiscal year. The document length is 3264 characters, which is relatively short but contains actual financial statements rather than just an announcement or link to a report. The presence of quarterly financial data and the nature of the content align with an Interim / Quarterly Report (IR).

105年第3季資產負債表
Interim / Quarterly Report Classification · 95% confidence The document contains a consolidated balance sheet with detailed financial data for multiple periods, including specific dates such as 105年09月30日 (which corresponds to a quarterly period in the Taiwanese calendar). The content is financial and substantive, showing assets, liabilities, and equity figures. The document length is 3601 characters, which is relatively short but contains actual financial statements rather than just an announcement or certification. The presence of quarterly financial data and the nature of the balance sheet indicate this is an Interim / Quarterly Report rather than a full Annual Report or just an announcement. There is no indication that this is a certification, announcement of report publication, or other types of filings. Therefore, the best classification is Interim / Quarterly Report (IR).
2016-11-09 Chinese
105年第3季權益變動表
Interim / Quarterly Report Classification · 95% confidence The document contains detailed financial tables labeled as "合併權益變動表" which translates to "Consolidated Statement of Changes in Equity." It includes data for the current period and the same period last year, with detailed accounting items such as common stock, capital surplus, legal reserve, undistributed earnings, retained earnings, and other equity items. The data is presented in a structured financial statement format with monetary amounts in thousands of New Taiwan Dollars. The document length is over 11,000 characters, indicating it is a substantive financial report rather than a brief announcement or certification. The content is consistent with a comprehensive financial report for a period shorter than a full fiscal year (the first three quarters of the year, 民國105年前3季, which corresponds to Q3 2016). Therefore, this document is best classified as an Interim / Quarterly Report (IR).
2016-11-09 Chinese
105年第3季海外子公司投資
Regulatory Filings Classification · 90% confidence The document is a financial disclosure related to investment in overseas subsidiaries, showing investment amounts, shareholding percentages, and recognized investment gains for a specific period (105th year, 3rd quarter). The content is tabular financial data about investments, not a full financial report or earnings release. The document length is short (648 characters), and it appears to be a regulatory disclosure of investment details rather than a comprehensive report. It does not fit the definitions of Annual Report, Interim Report, Earnings Release, or other detailed filings. Given the nature and format, it is best classified as a Regulatory Filing (RNS), which is the fallback category for miscellaneous regulatory disclosures that do not fit other categories.

105年10月內部人持股異動(事後)
Director's Dealing Classification · 100% confidence The document consists of detailed tables listing shareholdings and stock transactions by insiders, including directors, supervisors, and senior management of the company. It includes data on shares held, increases, decreases, and trust shares, with specific mention of identities such as chairman, directors, supervisors, and financial/accounting department heads. The content is focused on insider shareholdings and transactions rather than financial results, management changes, or meeting materials. This matches the definition of Director's Dealing (DIRS), which reports personal share transactions by company directors and executives (insider trades). The document length is sufficient and contains substantive data, not just an announcement or certification. Therefore, the appropriate classification is DIRS.

105年10月董事會成員及持股
Major Shareholding Notification Classification · 95% confidence The document is a detailed tabulation of shareholdings by insiders and related parties, including directors, supervisors, and senior management, with specific numbers of shares held, pledged shares, and related notes. It focuses on insider shareholdings and their status rather than financial results, management changes, or meeting materials. There is no indication of a report publication or announcement, nor is it a transcript or legal proceeding. The content aligns with a Director's Dealing or insider shareholding disclosure. Given the detailed insider shareholding data, the best fitting category is Major Shareholding Notification (MRQ). The document length is 3077 characters, which is consistent with a detailed shareholding notification rather than a brief announcement or a full report.
