Definition

Transactional Risk Due Diligence Advisory is the investigation and assessment of non-financial risks associated with a transaction, counterparty, beneficial owner, market or asset before commitment or closing.

Overview

The work complements financial, commercial, legal and operational diligence. It may examine sanctions, corruption, political connections, litigation history, source of wealth, reputation, cybersecurity or undisclosed relationships. Findings should be graded by evidence and relevance rather than presented as an unfiltered collection of adverse information.
