### Executive Summary

The Ultimate Beneficial Ownership (UBO) of **CÔNG TY TNHH VIỄN CHÍ BẢO** (Tax ID: 0111495421) is **Unresolved** at the natural-person level based on publicly accessible records. The entity is identified as a multi-member limited liability company (LLC) incorporated in Vietnam. **Bùi Duy Cương** is confirmed as the Legal Representative and Director, but his specific equity percentage is not disclosed in public tax or business summaries. A related entity, **CÔNG TY TNHH TRANG SỨC VIỄN CHÍ BẢO** (Tax ID: 0107994675), shares the same brand, address, and management circle (specifically **Bùi Đức Thiện**), suggesting a common control group. To resolve the UBO, a formal request for the "Danh sách thành viên" (List of Members) from the National Business Registration Portal is required.

### Investigation Steps

1.  **Entity Identity Verification:** Confirmed the target as **CÔNG TY TNHH VIỄN CHÍ BẢO** (VIEN CHI BAO COMPANY LIMITED), Tax ID **0111495421**. The entity is active, registered at P502 Tầng 5, số 39 đường Cầu Diễn, Phường Xuân Phương, Nam Từ Liêm, Hanoi.
2.  **Legal Form & UBO Threshold:** The entity is a "Công ty trách nhiệm hữu hạn 2 thành viên trở lên" (LLC with 2 or more members). Under Vietnamese Law on Enterprises, UBOs are typically natural persons holding >25% equity or exercising dominant control.
3.  **Management Identification:** Identified **Bùi Duy Cương** as the Legal Representative (*Người đại diện theo pháp luật*) and Director.
4.  **Corporate Group Analysis:** Identified a sister company, **CÔNG TY TNHH TRANG SỨC VIỄN CHÍ BẢO** (0107994675), managed by **Bùi Đức Thiện**. Both companies operate from the same address (39 Cầu Diễn) and use the same brand website (*vienchibao.com*).
5.  **Ownership Tracing:** Public tax and business directories (MaSoThue, DangKyKinhDoanh) confirm the multi-member status but redact the specific shareholder list and percentages behind a paywall/login requirement. No public disclosures of equity splits were found in open-source intelligence.
6.  **Evidence Register:**
    *   *Source 1:* National Business Registration Portal (dangkykinhdoanh.gov.vn). Status: Metadata reached; full member list restricted.
    *   *Source 2:* MaSoThue Business Directory. Status: Confirmed identity and Legal Representative.
    *   *Source 3:* Official Website (vienchibao.com). Status: Confirmed brand association and operational address.

### Confidence Score
45/100

### Rationale
The entity identity and legal representative are confirmed with high certainty (15/15). However, the ownership path is incomplete (10/30) because the specific list of members and their respective percentages are not publicly disclosed. While Bùi Duy Cương and Bùi Đức Thiện are high-probability candidates for ownership given their management roles and shared surname/address, their status as UBOs (natural persons with >25% interest) remains a lead rather than a confirmed fact (20/55 for UBO/Source/Consistency). The score is capped at 60 because a material path (the member list) remains unresolved.
