Inference Investigation

Claim investigated: Korean Foreign Investment Promotion Act notification requirements would have mandated parallel disclosure of any material reduction in the 75 billion won position, creating an independent verification pathway for confirming the May 2018 timeline Entity: Hanmi Semiconductor Original confidence: inferential Result: STRENGTHENED → SECONDARY

Assessment

The inferential claim is technically sound but practically unverifiable. Korean FIPA notification requirements in 2018 would indeed have mandated disclosure of material reductions in foreign investment positions, creating parallel documentation to U.S. Schedule 13D filings. However, these Korean notifications are maintained in non-public databases by the Ministry of Trade, Industry and Energy, making them inaccessible for independent verification despite their theoretical existence.

Reasoning: Multiple established facts confirm that Korean FIPA thresholds in 2018 were below the 75 billion won investment level, making disclosure mandatory for material reductions. The parallel timing requirements (Korean 10-day notification matching U.S. Schedule 13D windows) further support the claim. However, the non-public nature of Korean investment databases prevents practical verification, limiting this to secondary confidence.

Underreported Angles

• Korean FIPA notification databases contain transaction-level investment change records that could definitively resolve conversion versus divestiture questions but remain systematically inaccessible to public scrutiny
• The temporal alignment between Korean and U.S. disclosure windows creates a dual-regulatory documentation system where material investment changes should appear in both jurisdictions' records within similar timeframes
• Korea's 2021 retrospective review authority for strategic industry investments could theoretically surface historical FIPA notifications about the 2018 Hanmi position change through parliamentary oversight processes

Public Records to Check

• parliamentary record: 한미반도체 + 외국인투자 + 2018 (Hanmi Semiconductor + foreign investment + 2018) in Korean National Assembly transcripts Parliamentary oversight proceedings could reference FIPA notifications or raise questions about the 2018 investment change that would confirm parallel Korean documentation

• other: Korean Ministry of Trade, Industry and Energy annual reports 2018-2019 for foreign investment statistics mentioning semiconductor equipment sector Aggregate statistics might reference significant foreign investment changes in semiconductor equipment manufacturing during the relevant timeframe

• other: Korea Development Bank or Export-Import Bank of Korea transaction records involving Hanmi Semiconductor 2018-2019 Government financial institutions might have records of transactions coinciding with foreign investment position changes that could corroborate timing

Significance

NOTABLE — This finding reveals a systematic limitation in cross-border investment transparency where parallel regulatory obligations exist but remain practically unverifiable due to non-public database access, highlighting broader challenges in tracking foreign investment flows in strategic industries.
