Retrospective business valuations: value at a past date, with a clear evidence trail.

The valuation date and report date answer different questions

The valuation date is the point in time the assessment relates to. The report date tells the reader when the work was issued. Mixing them can lead to a present-day trading position being used to answer a historical question.

Start by recording why the earlier date matters, what interest is being valued and who will use the work. A past shareholder change, a comparison of offers or an ownership disagreement may require different instructions. Where an agreement or legal process determines the date or basis, provide those instructions and involve the relevant adviser.

Build an evidence timeline before building the model

Keep original file dates, versions and explanations. A spreadsheet named “budget final” is less useful than a dated version tied to a board pack or contemporary correspondence.

Later information: separate clarification from hindsight

Later evidence can sometimes help explain a condition that already existed at the valuation date. It should not simply replace the expectations and uncertainties relevant at that time. The treatment needs to follow the valuation purpose and applicable instructions.

Illustrative scenario: a business loses a major customer in August, after a valuation date of 31 March. The relevant questions include whether notice had already been received, what contract terms applied and what management knew in March. It would be misleading either to ignore an existing notice or automatically assume the later loss was certain months earlier.

Document when each fact became available and explain its proposed use. An explicit information cut-off and a separate subsequent-events note help readers understand the reasoning.

What if records are incomplete?

Identify missing information before promising a level of precision. It may be possible to reconcile records from bank information, management packs and other contemporary evidence, but reconstructed figures need a clear audit trail and limitations.

We discuss whether the available information supports the proposed assignment, what additional work is needed and whether scenarios are more appropriate than a single conclusion. We do not present missing evidence as certainty or assume current trading is representative of the historical position.

A dated scenario: what belongs in a 31 March assessment?

Hypothetical evidence exercise. Imagine a company valued at 31 March, with a report written in October. The task is to distinguish records describing the March position from information that only emerged later. The treatment of each item must fit the agreed basis and instructions.

Attach the underlying correspondence or original version where available. Later accounts are not automatically unusable, and later success is not automatically evidence that success was certain in March. The explanation needs to distinguish the condition, when it became known and how the report uses it.

Reconstruct the forecast without rewriting history

Preserve the original forecast and build a separate reconciliation. For each major assumption, record its contemporary support, the uncertainty acknowledged at the time and any later information used only to clarify it. Do not silently replace an original budget with a more accurate hindsight version.

Consider a budget expecting 20 new customer contracts. If the pipeline at the date consisted of two signed contracts, six advanced discussions and twelve early prospects, those categories should remain visible. A later actual result of 18 wins does not itself establish the probability that should have been attached to the original pipeline.

Where no contemporary forecast exists, explain how any reconstructed expectations were developed and where judgement is unavoidable. The report should tell the reader which records are original and which calculations were prepared later. If the evidence cannot support the requested conclusion, discuss a narrower question or explicit limitations before spending further time on modelling.

How to brief a retrospective valuation enquiry

Provide the proposed valuation date, purpose, business and ownership interest, the reason the date was selected, the records available and any deadline. Do not upload confidential records through the initial form. We discuss a suitable information-sharing route once suitability and scope have been considered.

For current sale preparation, a historical report may need to be complemented by an assessment of today’s position. A past-date valuation is not automatically a current guide price.
