Tracing findings back to their sources
A financial finding becomes useful when another reviewer can reconstruct its source, calculation, assumptions, and decision.
Preserve the source
Financial diligence depends on a chain of evidence. A reported metric may pass through an accounting export, a normalization step, a calculation, and an adjustment before appearing in a deliverable. Each step changes what a reviewer needs to understand.
Preserve the identity of the source file, the relevant row or document location, the entity, and the analysis period. Similar filenames or repeated exports are not enough to establish that two reviewers are looking at the same evidence.
Make transformations visible
Normalization should make records easier to analyze without erasing their origin. Mapping a ledger account into a financial category is a transformation that should remain understandable to the person reviewing the result.
Distinguish source values from calculated values. A financial figure copied from an accounting export is not the same kind of evidence as a metric derived from several transactions or a proposed management adjustment.
Review the calculation and the judgment
For a material calculation, document the inputs, period, treatment of missing values, and relevant exclusions. A total that reconciles does not by itself establish that the selected inputs are appropriate.
A reproducible calculation can still support the wrong interpretation. Review the business context, accounting treatment, and economic substance separately from the arithmetic.
Evidence gaps should remain visible through handoffs. If bank statements cover only part of the analysis period, a downstream summary should not imply that a full-period cash proof has been completed.
