Board or committee minutes recording decisions the executive made, delegated authority schedules, approved budgets bearing their sign-off, hiring and compensation approvals for subordinate managers, and the division's reporting lines over time. Pair each authority document with an example of it being used, rather than filing the policy alone.
Two chains of paper, not one
Keep the corporate chain and the personal chain separate as you gather material. The corporate chain shows the qualifying relationship and continuing international activity; the personal chain shows the executive's employment abroad and the appointment ahead. Redact commercially sensitive figures only after asking counsel what they need to see.
Note gaps candidly: a missing set of minutes is a fact to disclose and plan around, not a document to reconstruct after the event. Keep two chains of paper as the material is gathered. Within the second, pair each authority document with an example of it being used rather than filing the policy alone: board or committee minutes recording decisions the executive made, delegated authority schedules, approved budgets bearing their sign-off, hiring and compensation approvals for subordinate managers, and reporting lines over time.
Note gaps candidly, since a missing set of minutes is a fact to disclose and plan around rather than a document to reconstruct afterwards.
