Director's Dealing Classification · 95% confidence The document is a detailed tabulation of shareholdings and stock pledges by company insiders, including directors, supervisors, and senior management. It lists their current holdings, pledged shares, and related information. The content focuses on insider shareholdings and related disclosures rather than financial results, management changes, or meeting materials. This type of document corresponds to insider share transactions or holdings disclosures. Given the nature of the data, it fits best under Director's Dealing (DIRS), which covers reports of personal share transactions or holdings by company directors and executives. The document length is about 3,077 characters, which is consistent with a detailed insider holdings report rather than a brief announcement or a full financial report. Therefore, the classification is DIRS with high confidence.

105年8月背書保證與資金貸與
Regulatory Filings Classification · 95% confidence The document is a short disclosure from a listed company (台勝科) providing information about fund lending balances and endorsement guarantees for a specific month (August 2016). It contains tabulated financial data but is very brief (620 characters) and does not include comprehensive financial statements or detailed analysis. It appears to be a regulatory disclosure related to financial guarantees and fund lending, typical of a regulatory filing rather than a full report or announcement of a report. There is no indication that this is an annual or interim report, audit report, or any other detailed financial report. Given the short length and nature of the content, it fits best under Regulatory Filings (RNS).

Interim / Quarterly Report 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 compared to the previous year. It includes explanations about accounting standards (IFRS) and reporting practices. The document is short (776 characters) and primarily provides financial data for a specific month and year (August 2016, 民國105年08月). It does not contain a full annual or quarterly report, nor does it appear to be an announcement or certification. The content fits the definition of an Interim / Quarterly Report (IR) as it provides substantive financial data for a period shorter than a full fiscal year with analysis of revenue changes.

Director's Dealing Classification · 100% confidence The document consists of detailed tables listing shareholdings and stock ownership information of company insiders, including directors, supervisors, and senior management, with specific share counts and changes. It is focused on insider shareholdings and their changes, not on financial results, management changes, or meeting results. This matches the definition of Director's Dealing (DIRS), which covers reports of personal share transactions by company directors and executives (insider trades). The document length is sufficient and contains substantive data on insider holdings. Therefore, the appropriate classification is DIRS.

Director's Dealing Classification · 95% confidence The document is a detailed tabulation of shareholdings by insiders, including directors, supervisors, and senior management, showing their current holdings, pledged shares, and related information. It includes specific data on share counts and relationships but does not contain financial statements, earnings data, or report narratives. The content focuses on insider shareholdings and related disclosures, which aligns with the category of Director's Dealing (DIRS), which covers reports of personal share transactions by company directors and executives. The document length is about 3,077 characters, which is consistent with a detailed insider shareholding report rather than a full financial report or announcement. There is no indication that this is an announcement of a report or a certification letter, so it is not RPA or RNS. Therefore, the best classification is DIRS with high confidence.

105年第2季現金流量表
Interim / Quarterly Report Classification · 95% confidence The document contains a consolidated cash flow statement for the second quarter of the 105th year of the Republic of China calendar (equivalent to 2016), with detailed financial data including cash flows from operating, investing, and financing activities. The presence of actual financial figures and the period covered (half-year or quarterly) indicates this is a financial report for a period shorter than a full fiscal year. The document length is 2105 characters, which is relatively short but contains substantive financial data, so it is not merely an announcement or certification. Therefore, this document fits the definition of an Interim / Quarterly Report (IR).
