Why Report Structure Matters
An Own Risk and Solvency Assessment (ORSA) report should let its readers follow a connected argument: what risks does the insurer face, what is its current position, how might that position develop, and is capital adequate for the risks? A report that presents these matters as unrelated tables can obscure a vulnerability even when the underlying calculations are sound.
The structure should therefore move from context to assessment and then to conclusion. It should distinguish the insurer’s current position from projected positions, explain what adverse scenarios reveal, and make clear whether management actions are assumed or available. The report’s format must also be adapted to the insurer’s circumstances and applicable requirements; there is no single universal table of contents that fits every insurer.
A Logical Order for the Assessment
A practical structure gives the reader enough context to interpret each result before relying on it. The following sequence is a framework, not a mandated format. A report may combine sections or use different headings, provided its assessment remains complete and internally consistent.
State the assessment date, entities and businesses in scope, planning horizon, and basis used for projections. Identify important boundaries, such as material business excluded from a particular analysis.
Describe the material risks and how they arise from the insurer’s business and plans. This section gives the reader a reason to expect the capital measures and scenarios that follow.
Set out current available capital and the relevant internal capital need, using consistent definitions and a common valuation date. Explain any material difference between the measures used.
Show how the position is projected over the planning horizon under the central forecast. Distinguish this baseline from adverse scenarios and state whether projected management actions are included.
Present the adverse scenarios, their effects on available capital and capital need, and the resulting solvency position. Explain which exposures or assumptions drive the deterioration.
Describe actions reflected in the assessment, their conditions and feasibility, and the residual position after their effects. Disclose material model limitations and uncertainty that could affect interpretation.
Summarize whether capital is adequate for the insurer’s risks over the assessment horizon, including the circumstances in which the conclusion would be weaker or dependent on an action.
The ordering is important. If stress results appear before the risk profile, the reader may not understand why those scenarios were selected. If the conclusion appears without the current and prospective positions that support it, the report becomes an assertion rather than an assessment. Likewise, management actions should not be silently embedded in projections: the reader needs to know which results assume action and which do not.
Connect the Conclusion to the Results
The coverage ratio is a useful summary, but it is not the whole conclusion. It compresses two values into one and does not show how the position changes over time, what causes a stressed shortfall, or whether the assessment relies on actions that may not be feasible. The report should therefore include both the ratio and the underlying values, with the date, horizon, and scenario identified.
The relationship between the ratio and a surplus or shortfall follows directly from its definition. Let \(C\) be available capital and \(K\) be internal capital need, with \(K>0\). The capital margin is \(C-K\). Dividing this margin by \(K\) gives:
Thus a coverage ratio of 1.10 corresponds to a margin equal to 10% of internal capital need, while a ratio of 0.95 corresponds to a shortfall equal to 5% of that need. The ratio and the dollar margin answer related but different questions: the ratio expresses the margin relative to the need, and the margin expresses its size in currency. Both are useful in a report, provided the underlying measures are defined consistently.
Worked Example: Organizing a Current and Projected Position
A hypothetical insurer is preparing an ORSA assessment using a three-year planning horizon. At the assessment date, available capital is $480 million and internal capital need is $400 million. Its deterministic central forecast, before discretionary management actions, gives the following year-end amounts: year 1, $455 million of available capital and $410 million of need; year 2, $430 million and $425 million; year 3, $400 million and $440 million. Determine the current and projected coverage ratios, identify the key conclusion the report should make visible, and specify where these results belong in the report.
Method and assumptions. Use the definition of internal coverage ratio, with available capital and need measured on the same basis at each date. These are deterministic scenario values, not random variables, so no probability distribution is assumed. The example specifies no interest rate or mortality assumption because neither is used in these stated capital projections.
Current position. The ratio is \(480/400=1.2000\). The capital margin is \(480-400=\$80\) million.
Year 1. The ratio is \(455/410=1.109756\ldots\), or 1.1098 to four decimal places. The margin is \(455-410=\$45\) million.
Year 2. The ratio is \(430/425=1.011765\ldots\), or 1.0118 to four decimal places. The margin is \(430-425=\$5\) million.
Year 3. The ratio is \(400/440=0.909091\ldots\), or 0.9091 to four decimal places. The margin is \(400-440=-\$40\) million, a shortfall.
Report placement and interpretation. Put the assessment-date values in the current financial position section and the three year-end results in the prospective solvency section. The report should make clear that the central forecast, before discretionary actions, moves from an $80 million current margin to a $40 million year-3 shortfall. It should not describe the insurer as adequately capitalized throughout the horizon merely because its current ratio is above 1.
Check. Each margin equals available capital minus need, and each ratio uses the same date’s available capital and need. The falling ratios are consistent with the declining margins. A common mistake is to report only the current ratio of 1.2000 and omit the projected shortfall.
Present Stress Results With Their Implications
A stress section should identify what is changed, the resulting effect on the capital position, and the vulnerability the result indicates. A number such as “capital falls by $70 million” is difficult to interpret without stating whether available capital falls, internal need rises, or both. Report the starting position and stressed position on the same basis, then distinguish the scenario result from the conclusion drawn from it.
Where management actions are included, keep the calculation transparent. Show the position before action, the action’s assumed effect, and the residual position after action. State conditions that affect whether the action could be implemented. Do not treat a proposed action as certain merely because it can be represented numerically in a projection.
Worked Example: Showing a Stress and a Conditional Action
A hypothetical insurer has $500 million of available capital and $420 million of internal capital need before stress. A deterministic adverse scenario reduces available capital by $70 million and increases internal need by $30 million. Management is considering an action that, if completed, would add $35 million to available capital and reduce internal need by $10 million. Calculate coverage before stress, under stress before action, and under stress after action. Identify how the report should describe the action.
Method and assumptions. Apply each stated change to its specified measure, then divide available capital by internal need. All amounts are in millions of dollars and are deterministic scenario inputs; no probability distribution, interest rate, or mortality assumption is used.
Before stress. Coverage is \(500/420=1.190476\ldots\), or 1.1905 to four decimal places. The margin is \(500-420=\$80\) million.
Stressed, before action. Available capital becomes \(500-70=\$430\) million. Internal need becomes \(420+30=\$450\) million. Coverage is \(430/450=0.955556\ldots\), or 0.9556. The margin is \(430-450=-\$20\) million.
Stressed, after action. If completed, the action raises available capital to \(430+35=\$465\) million and reduces need to \(450-10=\$440\) million. Coverage is \(465/440=1.056818\ldots\), or 1.0568. The residual margin is \(465-440=\$25\) million.
Report interpretation. Present the stressed shortfall before action as the scenario result. Present the $25 million residual margin as conditional on completing the action, and describe the relevant feasibility conditions. The assessment should not imply that the stressed position is above need before action.
Check. The action improves the margin by \(35+10=\$45\) million, moving it from \(-\$20\) million to \(+\$25\) million. A common mistake is to add the $35 million capital benefit but leave need at $450 million, thereby omitting the separately stated $10 million reduction in need.
Disclose Limitations Where They Matter
A limitations section should help the reader understand what parts of the assessment are less certain and whether that uncertainty could affect the capital conclusion. Naming a limitation without describing its potential significance is not enough. Where possible, connect the limitation to a sensitivity, alternative assumption, data constraint, or range of outcomes. Do not imply that a sensitivity proves which assumption is correct; it shows how the result changes under the stated alternative.
Keep limitations distinct from scenario results. A stress scenario asks what happens under a defined adverse condition. A model limitation describes a constraint in the method, data, or assumptions used to estimate results. They may interact, but they are not interchangeable. The report should state which results are affected and whether the capital adequacy conclusion depends materially on the uncertain element.
Worked Example: Linking an Assumption Limitation to the Conclusion
A hypothetical insurer reports $400 million of available capital and a baseline internal capital need of $380 million. Its model does not fully reflect uncertainty in a particular exposure parameter. For a sensitivity, the insurer increases the need by $25 million while leaving available capital unchanged. Calculate baseline and sensitivity coverage and margins, then describe the appropriate report placement and interpretation.
Method and assumptions. Treat the sensitivity as a deterministic alternative assumption: need increases by $25 million, from $380 million to $405 million, and available capital remains $400 million. No probability distribution, interest rate, or mortality assumption is specified or needed.
Baseline. Coverage is \(400/380=1.052632\ldots\), or 1.0526 to four decimal places. The margin is \(400-380=\$20\) million.
Sensitivity. The revised need is \(380+25=\$405\) million. Coverage is \(400/405=0.987654\ldots\), or 0.9877. The margin is \(400-405=-\$5\) million.
Report interpretation. Describe the limitation in the limitations and uncertainty section, and show the sensitivity with the relevant solvency results. The conclusion should acknowledge that the baseline margin is modest and that the stated alternative assumption produces a shortfall. It should not present the baseline ratio alone as a complete account of the uncertainty.
Check. The $25 million increase in need changes the margin from \(+\$20\) million to \(-\$5\) million, exactly a $25 million deterioration. A common mistake is to apply the $25 million increase as a reduction to available capital as well as an increase to need, which would count an unstated effect twice.
Common Structure and Interpretation Traps
Several reporting errors can weaken an otherwise sound assessment:
- Mixing dates or measurement bases. A ratio is not interpretable if its numerator and denominator refer to different dates or inconsistent bases without explanation.
- Conflating current and prospective solvency. A favorable current position does not establish that capital remains adequate throughout the planning horizon.
- Hiding scenario assumptions. State what changes in a stress and whether its results include management actions.
- Presenting an action as guaranteed. Separate the result before action from the result conditional on action, and identify material feasibility conditions.
- Listing limitations without assessing relevance. Explain how a material limitation could affect the reported result or conclusion.
- Giving a conclusion that does not follow from the analysis. The conclusion should reflect the prospective and stressed positions, not only the most favorable measure.
A disciplined report structure does not replace actuarial judgment. It makes the judgment easier to examine: each conclusion can be traced back to a risk, a position, a projection or stress, and any assumptions or actions on which it depends.
Check Your Understanding
For each problem, focus on both the calculation and where the result belongs in a coherent ORSA report.
- A hypothetical insurer reports current available capital of $315 million and current internal need of $300 million. Its deterministic one-year forecast, before discretionary actions, is $290 million of available capital and $305 million of need. Calculate both coverage ratios to four decimal places and state the main reporting implication. (Answer: Current ratio \(315/300=1.0500\); forecast ratio \(290/305=0.9508\). The prospective section should disclose the forecast shortfall despite the current margin.)
- A hypothetical adverse scenario starts with available capital of $260 million and need of $240 million. It reduces available capital by $20 million and increases need by $15 million. Calculate stressed coverage and margin, and identify which two changes must be shown separately. (Answer: Stressed available capital is $240 million and need is $255 million; coverage is \(240/255=0.9412\), and margin is \(-\$15\) million. Report the reduction in available capital and increase in need separately.)
- A hypothetical insurer has stressed available capital of $350 million and stressed need of $360 million before action. A proposed action adds $18 million to available capital and reduces need by $8 million, if feasible. Calculate the post-action ratio and margin, and state how the report should qualify them. (Answer: Post-action capital is $368 million and need is $352 million; coverage is \(368/352=1.0455\), and margin is $16 million. Label these results as conditional on the action’s feasibility; before action the shortfall is $10 million.)
- A hypothetical assessment has $510 million of available capital and baseline need of $480 million. A stated sensitivity increases need by 7% while holding available capital constant. Calculate revised need, coverage to four decimal places, and margin. What limitation should the conclusion address? (Answer: Revised need is \(480(1.07)=\$513.6\) million; coverage is \(510/513.6=0.9930\); margin is \(-\$3.6\) million. The conclusion should acknowledge that the baseline margin does not persist under the stated sensitivity.)
