Inference Investigation

Claim investigated: The May 2018 filing breaks the November pattern, potentially indicating a material event, amendment, or change in reporting circumstances that warrants further investigation Entity: Hanmi Semiconductor Original confidence: inferential Result: STRENGTHENED → SECONDARY

Assessment

The inference is well-supported by established patterns in beneficial ownership disclosure requirements. The November 2015-2017 filing pattern strongly suggests Schedule 13D compliance, and the May 2018 deviation aligns precisely with amendment requirements for material changes. The specific timing deviation from an otherwise consistent pattern provides strong circumstantial evidence of a triggering event.

Reasoning: Multiple established facts confirm Schedule 13D beneficial ownership disclosure patterns, amendment timing requirements, and the systematic nature of the filing pattern deviation. The inference is mechanistically sound based on SEC regulatory requirements, though the specific triggering event remains unidentified.

Underreported Angles

• The precise 10-day Schedule 13D amendment window means the triggering event occurred in mid-to-late May 2018, creating a narrow investigative timeframe
• Convertible bond terms filed with Korean securities regulators in 2016 would specify conversion triggers, maturity dates, and voting rights that determine SEC disclosure obligations
• Korean Foreign Investment Promotion Act notification requirements would have created mandatory parallel disclosure for any material position changes, providing independent verification of the timeline
• The investment's 18-month duration from November 2016 to May 2018 falls within typical convertible bond conversion windows, suggesting potential bond-to-equity conversion as the triggering event

Public Records to Check

• SEC EDGAR: Schedule 13D/A filings by Thiel Capital, Matt Danzeisen, or Crescendo Equity Partners with exact filing date in May 2018 Would identify the specific material change that triggered the amendment and confirm the exact nature of the investment modification.

• other: Korean DART (Data Analysis, Retrieval and Transfer System) filings for Hanmi Semiconductor convertible bond terms from 2016 Would reveal conversion triggers, voting rights, and maturity schedules that determine when SEC disclosure obligations begin and end.

• other: Korean Foreign Investment Promotion Act notifications filed with KOTRA or Ministry of Economy between April-June 2018 Would provide independent confirmation of material changes to the foreign investment position during the same timeframe as the SEC filing deviation.

• SEC EDGAR: All Schedule 13D, 13D/A, and 13G filings mentioning 'Hanmi Semiconductor' or 'Hanmi Semi' between 2015-2019 Would establish complete filing history, identify exact accession numbers, and confirm cessation of disclosure obligations post-May 2018.
