107年第1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 (e.g., 107年03月31日, 106年12月31日) and amounts in thousands of New Taiwan Dollars. The presence of comprehensive financial statements with asset, liability, and equity breakdowns indicates this is a financial report rather than a brief announcement or certification. The document length is 3546 characters, which is relatively short but contains substantive financial data. The content corresponds to a quarterly or interim financial report rather than a full annual report, as it covers a specific quarter (first quarter of year 107 in the Taiwanese calendar, which corresponds to 2018). There is no indication that this is an announcement of a report or a certification. Therefore, the document is best classified as an Interim / Quarterly Report (IR).

107年第1季權益變動表
Interim / Quarterly Report Classification · 95% confidence The document contains detailed financial tables showing changes in equity for a specific fiscal period (民國107年第1季, which corresponds to the first quarter of 2018). It includes line items such as common stock, capital surplus, retained earnings, and comprehensive income components. The presence of detailed financial data for a quarterly period indicates this is a substantive financial report rather than a brief announcement or certification. The document length is 3316 characters, which is relatively short but contains actual financial data, not just a notice or link to 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 financial statements and analysis. Therefore, the appropriate classification is IR (Interim / Quarterly Report).

107年4月營業收入
Regulatory Filings Classification · 90% confidence The document is a summary report of monthly and cumulative net operating revenue figures for a company named 台勝科, with data presented for April 2018 (民國107年04月). It includes percentage changes compared to the previous year and explanatory notes about accounting standards and reporting practices. The document is very short (781 characters) and primarily provides financial summary data without detailed financial statements or management discussion. It does not appear to be a full financial report like an Annual Report (10-K) or Interim Report (IR). It also does not fit categories like Earnings Release (ER) because it lacks key highlights or narrative. The document is more of a regulatory or public disclosure summary of financial data, typical of a Regulatory Filing (RNS) in the context of Taiwanese public company disclosures. Therefore, the best classification is Regulatory Filings (RNS).

107年4月背書保證與資金貸與
Regulatory Filings Classification · 95% confidence The document is a financial disclosure from a listed company (台勝科) providing information about fund loans and endorsement guarantees for a specific month (April 2018, 民國107年04月). It contains tabulated financial data about loan balances and guarantees but does not include comprehensive financial statements or detailed analysis. The content is typical of a regulatory disclosure or compliance filing rather than a full financial report or announcement. The document length is short (621 characters), and it does not indicate it is an announcement of a report publication. Given the nature and format, this fits best under Regulatory Filings (RNS), which is the fallback category for miscellaneous regulatory disclosures that do not fit other specific categories.

107年04月內部人持股異動(事後)
Director's Dealing Classification · 95% confidence The document consists of detailed tables listing shareholdings and stock transactions by insiders, including directors, supervisors, and senior management of the company 台勝科. It includes data on shares held, increases, decreases, and trust shares, with specific mention of roles such as chairman, directors, supervisors, general manager, and financial/accounting department heads. The content focuses on insider shareholdings and transactions rather than financial results, management changes, or meeting materials. 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 and changes. Therefore, the appropriate classification is DIRS.

107年04月董事會成員及持股
Major Shareholding Notification Classification · 95% confidence The document is a detailed tabulation of shareholdings and pledges by insiders and related parties of the company 台勝科 (Taiwan Semiconductor). It lists shareholdings of directors, supervisors, and senior management, including their pledged shares and related party holdings. The document is focused on insider shareholdings and does not contain financial statements, earnings data, or management discussion. It is not an announcement of a report but a disclosure of insider shareholdings. This matches the definition of a Major Shareholding Notification (MRQ), which involves notification of changes or status of significant share ownership levels by insiders or major shareholders. The document length is about 3,074 characters, which is consistent with a detailed shareholding notification rather than a full report or announcement of a report publication.
