Building Blocks explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
A recognised methodology, a detailed model and extensive disclosures do not, individually or together, make a report defensible. What matters is how the elements support one another.
The ten building blocks
| Building block | Contribution |
|---|---|
| Appropriate methodology selection | Ensures the approach suits the asset, business and assignment context |
| Evidence-based assumptions | Provides a supportable foundation for the conclusions |
| Professional judgement | Enables reasoned decision-making where uncertainty or incomplete information exists |
| Transparent disclosures | Communicates assumptions, limitations, risks and uncertainty |
| Speaking documentation | Explains the reasoning process underlying key conclusions |
| Robust work files | Creates an evidentiary trail capable of supporting the process |
| Internal quality review | Identifies weaknesses, inconsistencies and gaps before issuance |
| Consistency of analysis | Keeps assumptions, conclusions and disclosures aligned throughout the report |
| Professional scepticism | Strengthens the reliability of information relied upon and conclusions reached |
| Clear communication | Enables stakeholders to understand how the conclusion was derived |
The significance of these elements lies not in their individual existence but in the manner in which they interact, and three specific failure combinations are named:
Strong assumptions supported by weak documentation remain vulnerable — the reasoning existed but cannot be shown.
Comprehensive disclosures cannot compensate for inadequate analysis — describing a gap is not filling it.
A technically sound valuation may still face scrutiny if the report fails to explain the reasoning that led to the conclusion — correct, and unexplained.
Each pairs a genuine strength with a specific gap, which is why building blocks cannot be traded off against one another. A report is not defensible on average.
What the objective actually is
A recurring theme is that valuation is ultimately an exercise in professional judgement applied to imperfect information. The objective of a defensible process is therefore not to eliminate uncertainty but to ensure that uncertainty is:
- identified;
- evaluated;
- documented; and
- appropriately communicated.
The five practical tests
In practical terms, a defensible report is one where:
- significant assumptions are capable of being substantiated;
- material conclusions can be traced to supporting evidence;
- areas of uncertainty are transparently disclosed;
- professional judgements are appropriately documented; and
- the reasoning process can be understood by an independent reviewer.
Where the building blocks come from
Read against the whole framework, each element has a chapter behind it: methodology selection and its justification; assumption development and the disclose-and-justify discipline; the five-section work file and its traceability rule; disclosure architecture and placement; sensitivity analysis as the quantified expression of uncertainty; and the pre-issuance review checklists.
The list is not a summary of good intentions — it is an index of practices, each with its own evidence requirements.
What the report becomes
When these elements are present, the report becomes more than a statement of value. It becomes a transparent record of the analysis, judgement and evidence that support the valuation conclusion.
Common mistakes
- Relying on one strong element to carry a weak one.
- Adding disclosures in place of analysis.
- Producing sound analysis the report never explains.
- Treating uncertainty as something to be removed rather than communicated.
