Inference Investigation

Claim investigated: The SEC filings attributed to Hanmi Semiconductor (2015-2018) most likely represent Schedule 13D or 13G beneficial ownership disclosures filed by U.S. investors (Thiel Capital, Crescendo Partners, Danzeisen) regarding their Hanmi holdings, rather than corporate filings by Hanmi itself as a foreign private issuer Entity: Hanmi Semiconductor Original confidence: inferential Result: STRENGTHENED → SECONDARY

Assessment

The inference is strongly supported by multiple converging lines of evidence. The absence of accession numbers, the timing pattern inconsistent with foreign private issuer reporting but consistent with beneficial ownership disclosure schedules, and the direct correlation with known U.S. investor activity create a compelling case. The strongest counterargument would be if Hanmi had established ADR programs or other U.S. listing mechanisms, but no evidence supports this alternative explanation.

Reasoning: Multiple technical indicators strongly support this inference: (1) Schedule 13G annual amendments must be filed by February 14, making November filings inconsistent with 13G requirements and pointing to 13D filings; (2) the May 2018 deviation suggests a triggering event consistent with 13D amendment requirements; (3) absence of accession numbers indicates data extraction captured company references in investor filings rather than company-filed documents; (4) temporal correlation with known convertible bond investment creates clear causal pathway. While not directly verified through primary source examination, the technical evidence is compelling enough to elevate from inferential to secondary confidence.

Underreported Angles

• The distinction between 13D and 13G filing schedules provides a forensic pathway to determine investor intent and activity level that has not been systematically explored in coverage of Thiel/Danzeisen investments
• The absence of accession numbers in SEC filing records suggests a systematic data extraction methodology that captures portfolio holdings mentions rather than primary filings, indicating broader implications for how foreign company 'SEC filings' are catalogued
• The May 2018 timing deviation from the November pattern represents a potential material triggering event (conversion, sale, or change in investment purpose) that coincides with broader Thiel portfolio movements during that period
• Convertible bond structures in Korean KOSDAQ companies create complex beneficial ownership calculations for SEC disclosure purposes that may not align with traditional equity ownership thresholds

Public Records to Check

• SEC EDGAR: Schedule 13D filings by Thiel Capital, Crescendo Partners, or Matt Danzeisen during 2015-2018 period Would directly confirm that these were investor filings rather than issuer filings and identify the specific beneficial ownership percentages and conversion terms

• SEC EDGAR: Schedule 13G filings mentioning Hanmi Semiconductor as subject company during 2015-2018 Would confirm passive investor status and explain the filing schedule patterns observed

• SEC EDGAR: Form 13F quarterly institutional holdings reports mentioning Hanmi Semiconductor 2015-2018 Would provide additional confirmation of U.S. institutional ownership and filing obligations

• SEC EDGAR: ADR registration statements or Form 20-F filings by Hanmi Semiconductor Would definitively rule out the alternative explanation that these were direct issuer filings by Hanmi as a foreign private issuer

• other: Korean DART system - Hanmi Semiconductor foreign investment disclosure reports 2016 Would confirm the convertible bond investment structure and terms that triggered U.S. disclosure requirements

Significance

SIGNIFICANT — This finding clarifies the nature of foreign company appearances in SEC databases and demonstrates how convertible bond investments by prominent U.S. investors create disclosure trails that can be misattributed to the foreign portfolio companies themselves. It also provides a methodological framework for distinguishing between direct foreign issuer SEC compliance and indirect disclosure through U.S. investor beneficial ownership reporting.
