What We Do

Quantifying loss to a standard that holds up.

Business interruption claims require the reconstruction of what would have happened financially if the interruption had not occurred. That hypothetical - the "but for" position - must be built on defensible assumptions and sound methodology.

Key Ledgers prepares quantum reports for both insurance claims and civil litigation. Instructions come from policyholders, insurers, claimant and defendant solicitors.

  • Calculation of the "but for" trading position

Case Study
Real instruction - name withheld

Business Interruption Claim

Reconstruction of pre-interruption financial performance and defensible loss modelling used to support a six-figure insurance recovery. The report withstood challenge from the insurer's own appointed expert. Key issues included the appropriate base period for performance, the treatment of industry trends and the calculation of the indemnity period.

Six-figure recovery supported

"The report was watertight. Every assumption was documented, every calculation was traceable. The insurer's expert had nothing to challenge."
