The Proof System

Why auditors trust our work.

Auditors rely on evidence. We design deliverables to make that evidence explicit. Every FairvalueX deliverable provides four proofs that satisfy audit scrutiny before they ask.

The Four Proofs

What every audit engagement requires—built into every deliverable.

Proof 1
Proof of Method

Clear documentation of why this valuation approach was selected. Method choice follows explicit decision rules tied to asset characteristics, market conditions, and applicable standards.

Proof 2
Proof of Inputs

Every input sourced and classified by reliability tier. Client-provided data distinguished from third-party sources. Timestamps and version control for all key assumptions.

Proof 3
Proof of Logic

Complete mapping from inputs to conclusion. No black boxes. Every calculation step documented. Every formula traceable. An auditor can reconstruct the entire analysis.

Proof 4
Proof of Reasonableness

Cross-checks against market data. Sensitivity analysis showing value drivers. Narrative alignment between qualitative story and quantitative output.

Each proof appears as a distinct section in every deliverable: method rationale, sourcing index, model trace map, and reasonableness/sensitivity pack.

The Real Value

What clients actually buy.

Clients don't buy valuations. They buy risk reduction. Specifically:

Reduced audit risk

Work that passes audit review the first time

Reduced regulatory exposure

Standards-compliant documentation that satisfies examiners

Reduced personal accountability risk

Clear evidence that reasonable care was taken

Confidence in critical decisions

Numbers you can stand behind when challenged

Our commitment

"We produce audit-defensible valuations with reproducible logic."

"Every assumption is sourced, classified, and explainable."

"Speed comes from systems—not shortcuts."

"We reduce audit and decision risk."
