Federal contracts (USAspending, last 180 days)
No award action to a recipient named exactly "TAIWAN SEMICONDUCTOR MANUFACTURING CO LTD" in the last 180 days. Subsidiaries and differently-spelled recipients are not matched — search contracts.
Lobbying (Senate LDA, as client)
No LDA filing names "TAIWAN SEMICONDUCTOR MANUFACTURING CO LTD" as the client in the last two years. Filings under a subsidiary or trade-association name are not matched — search lobbying.
Sources and method
Insiders and their transactions come from SEC EDGAR Form 4 filings for this issuer. Contracts and lobbying are matched by exact normalized name (suffixes like Inc./Corp. ignored) to USAspending recipients and LDA clients — a conservative match that misses subsidiaries on purpose. See methodology and corrections.
