How deal attribution works: Deals are attributed to individuals based on their role at a firm during the transaction period. C-suite executives and senior partners/MDs are attributed deals where their firm was involved as a principal, counsel, advisor, or lender. This is an inference — not all attributed individuals necessarily worked directly on every deal.
