104年第2季資產負債表
Interim / Quarterly Report Classification · 95% confidence The document contains detailed financial data including a consolidated balance sheet with specific dates (e.g., 104年06月30日, which corresponds to the second quarter of 2015 in the Taiwanese calendar). It includes comprehensive financial statement line items such as assets, liabilities, equity, and subtotals. The presence of actual financial figures and multiple comparative periods indicates this is a substantive financial report rather than a brief announcement or certification. The document length is 4548 characters, which is sufficient for a quarterly or interim report. The content is consistent with an Interim / Quarterly Report (IR) rather than an Annual Report (10-K) or Earnings Release (ER), as it provides detailed financial statements rather than just highlights. There is no indication that this is an announcement or a certification, so it is not RPA or RNS. Therefore, the best classification is Interim / Quarterly Report (IR). Q2 2015

104年第2季權益變動表
Interim / Quarterly Report Classification · 95% confidence The document contains detailed tables of consolidated equity changes for the first half of the year 2015 (民國104年上半年度) and the same period in the previous year. It includes financial data such as common stock, capital surplus, legal surplus reserve, special surplus reserve, undistributed earnings, retained earnings, and other equity items. The presence of detailed financial data for a half-year period indicates this is a financial report for an interim period rather than a brief announcement or a certification. The document length is 4264 characters, which is relatively short but contains substantive financial data, so it is not merely an announcement of a report. The content matches the characteristics of an Interim / Quarterly Report (IR) as it covers a period shorter than a full fiscal year and includes actual financial statements and analysis. Therefore, the appropriate classification is IR (Interim / Quarterly Report). H1 2015

104年第2季海外子公司投資
Interim / Quarterly Report Classification · 85% confidence The document contains detailed financial data about investments in overseas subsidiaries, including ownership percentages, original investment amounts, investment balances, and recognized investment gains or losses for the current period. The data is presented in a tabular format with notes explaining accounting treatments, consistent with equity method accounting disclosures. The document length is 1558 characters, which is relatively short and focused on specific investment details rather than a full financial report. There is no indication that this is an announcement or a certification. The content aligns with detailed financial information typically found in an Interim / Quarterly Report (IR), as it provides substantive financial data for a specific period (104年2季, which corresponds to the second quarter of the 104th year in the Taiwanese calendar). Therefore, the document is best classified as an Interim / Quarterly Report (IR). H1 2015

104年第2季大陸投資
Regulatory Filings Classification · 95% confidence The document is a detailed tabular disclosure of investments in mainland China by a Taiwanese listed company, including capital amounts, investment methods, cumulative investment amounts, and recognized investment gains or losses. It includes notes explaining investment methods, accounting bases for investment gains/losses, and regulatory investment limits. The document is 1606 characters long, which is relatively short and appears to be a regulatory disclosure rather than a full financial report. It does not contain comprehensive financial statements or management discussion but rather specific investment-related data. This type of document aligns with a Regulatory Filing (RNS) as it is a compliance disclosure about overseas investments, not a full annual or interim report, audit report, or other specific report types.

104年07月內部人持股異動(事後)
Director's Dealing Classification · 100% confidence The document consists of detailed tables listing shareholdings of company insiders, including directors, supervisors, general managers, and other executives. It shows the number of shares held, changes in holdings, and related information for various insiders. This type of document is typically a report on insider share transactions or holdings by directors and executives. There is no indication of financial statements, earnings data, or meeting materials. The content matches the definition of a Director's Dealing report, which reports personal share transactions by company directors and executives (insider trades). The document length is sufficient and contains substantive data on insider holdings and changes, confirming it is not a mere announcement or certification. Therefore, the appropriate classification is Director's Dealing (DIRS).

104年07月董事會成員及持股
Director's Dealing Classification · 95% confidence The document contains detailed tables listing shareholdings of company insiders, including directors, supervisors, and executives, with specific numbers of shares held, pledged shares, and related percentages. It is a disclosure of insider shareholdings and their changes. There is no indication of financial statements, earnings data, or meeting materials. The content aligns with reporting of insider shareholdings or director dealings rather than a full report or announcement of voting results. Given the nature of the data—personal share transactions or holdings by company directors and executives—this fits the definition of Director's Dealing (DIRS). The document length is under 5,000 characters and is a direct disclosure, not a report publication announcement or regulatory filing. Therefore, the classification is DIRS with high confidence.
