Summary
Concise executive summary that states the triggering event, primary operational impacts, estimated financial exposure, and the reporting period covered. Keep it factual and dated for audit purposes.
Use a Business Impact Letter to communicate verified effects of an event to executives, partners, insurers, or regulators. It creates an auditable record of losses, mitigation measures, and proposed remedies that supports claims, contractual discussions, and compliance reporting.
Internal teams and external recipients prepare or review Business Impact Letters to document impact for continuity, insurance, compliance, and contract management.
Use clear formatting and supporting attachments to make reviews faster and reduce follow-up questions.
The Incident Manager assembles factual details, compiles supporting documents, and prepares the draft Business Impact Letter. They coordinate with operations, IT, and finance to ensure figures are accurate; their signature confirms factual accuracy but may require executive approval for legal assertions.
The Chief Financial Officer reviews and certifies financial estimates, loss calculations, and accounting treatments in the letter; their approval is often required for insurance claims and contract negotiations. CFO sign-off lends financial authority and supports recovery and reimbursement processes.

Itemized financial and operational losses with calculation methods, time frames, and assumptions. Include direct costs, lost revenue estimates, and any third-party charges or penalties that apply.
Chronological account of events, detection time, mitigation steps taken, and ongoing actions. Use timestamps (MM/DD/YYYY HH:MM) to support forensic or insurance reviews and establish causal chains.
Document immediate and planned mitigation measures, responsible parties, expected completion dates, and interim workarounds. Note resource constraints and any external dependencies that affect recovery timelines.
List and attach supporting evidence such as incident reports, invoices, communications, contracts, supplier notices, insurance policies, and photos or system logs that substantiate claims.
Identify author, approver, and distribution list. Each signatory should include name, title, contact, and signature date to confirm accuracy and authority for the statement.

Keep an editable DOCX draft for internal use and recordkeeping; mark the final signed version as authoritative and archive the signed PDF for external distribution.
Export line-item loss tables and financial summaries as CSV for accounting systems or insurer claim portals; include reference IDs to connect records.
