Classification, recipients, controls, access duration, onward disclosure, monitoring, exceptions, incident response, return and destruction should be explicit.
Each gate should test necessity, proportionality, authority, conflicts, competitive fairness, privacy, market integrity, security and reversibility. Gaps remain until evidence is complete, advice is current, recipients are controlled and the company can explain why the disclosure served a legitimate transaction purpose.
32. Prepare for leakage
The board should define detection, containment, legal assessment, board escalation, regulatory analysis, market disclosure and stakeholder communications. The immediate output is a leak response plan with named owners, dates, source evidence, approval status and open exceptions.
The analytical objective is to determine whether the company can act before misuse, rumour or loss of confidentiality compounds harm. Reviewers should reconcile board authority, transaction rules, constitutional documents, confidentiality terms, data-room records, adviser work, security evidence, financing materials and applicable advice. Each access decision should state its purpose and minimum sufficient information.
The framework should allocate responsibility across independent directors, management, buyer representatives, company and bidder advisers, data-room administrators, clean-team members, finance providers, employees and regulators. Classification, recipients, controls, access duration, onward disclosure, monitoring, exceptions, incident response, return and destruction should be explicit.
Each gate should test necessity, proportionality, authority, conflicts, competitive fairness, privacy, market integrity, security and reversibility. Gaps remain until evidence is complete, advice is current, recipients are controlled and the company can explain why the disclosure served a legitimate transaction purpose.
