Overseas subsidiary internal reviews: From periodic execution to a sustainable management framework

As overseas business operations expand, the importance of internal reviews of overseas subsidiaries continues to grow. However, in practice, we often observe that although reviews are conducted on a regular basis, the results are not sufficiently linked to group-level risk management and the strengthening of internal controls. This issue does not stem from deficiencies in the execution of reviews themselves, but rather from structural limitations in operating models where review results are not systematically translated into ongoing management and follow-up.

Key challenges

• Review results are difficult to compare and utilize due to inconsistent criteria across subsidiaries
• Imbalances in review coverage caused by limited internal resources
• Insufficient follow-up and monitoring of remediation actions
• Repeated occurrence of the same issues across entities

Direction for improvement

An effective overseas subsidiary review framework should be built on the following foundations:

• Establishment of standardized, group-wide review criteria
• Risk-based determination of review scope and prioritization
• Consistent reporting structures that enable comparability of results
• A structured remediation and follow-up management process

In this context, the use of external professional expertise should not be viewed as a replacement for internal functions, but rather as a practical means to enhance the effectiveness and sustainability of the overall management framework.

Expected benefits

• Improved consistency and reliability of review outcomes
• Expanded management coverage across overseas subsidiaries
• Reduction of recurring issues and enhancement of internal control maturity
• Greater usability of review results in reporting to management and the audit committee

Shifting the focus: From “Are reviews performed?” to “Is the framework sustainable?”

Overseas subsidiary internal reviews should not be regarded as standalone inspection activities, but as an integral component of the group’s overall risk management framework. Organizations are encouraged to assess whether their current operating model enables review results to be translated into effective and continuous management, and, where necessary, to consider transitioning to a more structured and sustainable approach.
