107年05月董事會成員及持股
Director's Dealing Classification · 95% confidence The document is a detailed tabulation of shareholdings by insiders and related parties of the company 台勝科 (Taiwan Semiconductor). It lists the number of shares held by directors, supervisors, and senior management, including pledged shares and shares held by spouses or minors. The document also includes notes about the absence of certain managerial positions and clarifies the calculation methods for shareholding percentages. There is no indication of a meeting, voting results, financial performance data, or legal proceedings. The content is focused 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 3,074 characters, which is consistent with a detailed insider shareholding report rather than a brief announcement or a full financial report. Therefore, the most appropriate classification is DIRS.

107年5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 for May 2018 (民國107年05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 contains no detailed financial statements or management discussion. It appears to be a periodic revenue summary rather than a full financial report or earnings release. There is no indication of a conference call transcript, AGM materials, or regulatory filings. Given the nature of the data and the short length, this fits best as a Regulatory Filing (RNS) which is a general category for miscellaneous regulatory announcements and compliance documents that do not fit other categories.

107年5月背書保證與資金貸與
Regulatory Filings Classification · 90% confidence The document is a financial disclosure from a listed company (台勝科) providing information about fund lending balances and endorsement guarantees for a specific month (May 2018, 民國107年05月). The content is tabular and quantitative but very brief (621 characters), focusing on financial data related to loans and guarantees rather than a full financial report or announcement. It does not contain comprehensive financial statements or management discussion. Given the short length and nature of the data, it is not an Annual Report, Interim Report, or Earnings Release. It is also not a regulatory announcement or certification. The document fits best as a Regulatory Filing (RNS) because it is a general regulatory disclosure of financial information that does not fit other specific categories.

107年05月僑外投資持股
Major Shareholding Notification Classification · 95% confidence The document is a statistical table showing the shareholding situation of overseas and mainland China investors, including detailed numbers of shares held before and after certain dates, and explanations for differences. It includes data on foreign and mainland investors' holdings, stock codes, and share counts. There is no indication of a report publication, financial results, management discussion, or regulatory certification. The document is a regulatory disclosure about shareholding changes related to a shareholder meeting (股東會) but does not announce voting results or dividend information. It fits best as a Major Shareholding Notification (MRQ) because it reports changes in significant share ownership levels and detailed shareholding statistics. The document length is short and focused on shareholding data, consistent with MRQ filings.
