Designed for: accountants, finance managers, controllers, process owners and reviewers working inside organisations.
1. Process objective
Create a repeatable process for judgments, assumptions, evidence, approvals and roll-forwards. The process should produce a result that is complete, accurate, supported, approved and traceable to the financial statements.
2. Core workflow
- Maintain an estimate and provision register.
- Identify the obligating event or estimation trigger.
- Use reliable data and document assumptions.
- Perform sensitivity and back-testing where useful.
- Roll forward opening, utilisation, addition, reversal and closing balances.
3. Practical situation
Warranty provisions are estimated using claim history by product generation, adjusted for known design issues. The model is compared with actual claims each quarter.
4. Ownership model
| Role | Responsibility |
|---|---|
| Preparer | Obtains source data, performs the calculation or reconciliation and explains exceptions. |
| Process owner | Confirms operational facts, resolves missing information and approves business assumptions. |
| Reviewer | Challenges completeness, accounting treatment, material judgments and unresolved items. |
| Controller | Monitors completion, escalates risk and ensures the result flows correctly into reporting. |
5. Minimum evidence pack
- Approved policy or process note
- Source-system report and data lineage
- Reconciliation or calculation schedule
- Exception log with owner and ageing
- Preparer and reviewer sign-off
6. Reviewer challenge
- Is the population complete and tied to the general ledger?
- Are aged or unusual items separately explained?
- Does the treatment follow the entity policy and applicable standard?
- Are assumptions supported by current information?
- Is every adjustment posted, approved and traceable?
Newton of Accounts approach:
Conceptual clarity is drawn from CA Pranav P. Tulshyan’s accounting teaching work, then independently developed into professional workflows, controls and documentation for company accounts.
