Two Different Questions About Solvency
An insurer may meet a prescribed regulatory capital requirement and still have a material concern about its ability to carry out its strategy or withstand a risk it considers important. The distinction is not that one assessment matters and the other does not. Regulatory compliance tests whether the insurer satisfies applicable prescribed requirements; an ORSA asks the insurer to assess its own risks and solvency in the context of its business.
A regulatory capital calculation is typically governed by requirements set outside the insurer, including specified definitions, assumptions, and measurement rules. An insurer’s own risk and solvency assessment (ORSA), by contrast, is an insurer-owned assessment of its material risks and whether its financial resources and plans are appropriate for its risk profile and strategy. The form and detailed requirements of regulatory capital and ORSA vary by jurisdiction. The distinction here is about purpose, not a claim that every jurisdiction uses the same formulas or thresholds.
A useful way to keep the purposes separate is to ask two questions. First, does the insurer meet the applicable regulatory requirement? Second, does the insurer consider its resources and plans adequate for the risks it actually faces and expects to take? The answers can differ without contradiction. For example, the insurer may pass the prescribed test but identify a concentration, a planned expansion, or a severe plausible loss that warrants a change in plans.
Capital Ratios: Useful, but Limited
For a simple illustration, let \(C\) denote capital resources measured under a specified regulatory basis and let \(R\) denote the corresponding regulatory capital requirement. When \(R>0\), the ratio \(C/R\) summarizes the relationship between resources and that requirement. A ratio of at least 1.00, or 100%, indicates compliance only if the applicable rule defines compliance in this way and the figures are measured on the required basis.
That ratio is not a complete statement about the insurer’s own view of solvency. It is tied to a particular measurement basis and time. It does not, by itself, tell the reader whether a planned strategy could materially change the risk profile, whether a severe scenario could weaken resources, or whether the insurer’s own tolerance for risk would be exceeded. Those questions require the insurer to consider its own risk profile and the circumstances relevant to its business.
An insurer may also set an internal target for planning. For illustration, let \(T\) be an internal target expressed as a multiple of the regulatory requirement. This is not a universal ORSA formula or a prescribed regulatory standard. It is simply one possible way to express a company’s own planning threshold. Meeting a regulatory floor does not necessarily mean meeting that target.
Worked Example: A Growth Plan Passes the Floor but Misses an Internal Target
A hypothetical insurer has \(C=\$960\) million of regulatory-basis capital and \(R=\$800\) million of regulatory capital requirement. For this example, assume compliance requires a ratio of at least 100%. The insurer is considering a growth plan. A planning projection estimates that, after the growth-related strain, capital will be \(\$930\) million and the regulatory requirement will be \(\$840\) million. The insurer’s own planning target is 115% of the projected requirement. Determine the current result and the projected results.
Method. Calculate the current and projected regulatory ratios separately, then compare projected capital with the internal target. All amounts are hypothetical and in millions of dollars.
Current compliance. The current ratio is \(\$960/\$800=1.20\), or 120%. Since 120% is greater than the assumed 100% floor, the insurer currently complies under the stated test.
Projected regulatory ratio. After the plan, the projected ratio is \(\$930/\$840=1.107142\ldots\), or 110.7% when rounded to one decimal place. It remains above the assumed 100% regulatory floor.
Projected internal target. The target is \(1.15\times \$840=\$966\) million. Projected capital of \(\$930\) million is \(\$966-\$930=\$36\) million below that target.
Conclusion and check. The plan remains above the assumed regulatory floor, but it does not meet the insurer’s own target. The result does not establish that the plan must be rejected; it identifies an own-purpose concern for assessment and decision-making. A common mistake is to call the plan adequate solely because 110.7% exceeds 100%. That calculation answers the regulatory-floor question, not whether the insurer’s stated 115% target is met.
Why a Current Pass Does Not Guarantee a Future Pass
The logical distinction can be shown with a simple stress calculation. Suppose \(C\) and \(R\) are current capital resources and requirement. In a hypothetical one-period stress, let \(L\) be the reduction in resources and let \(\Delta R\) be the change in the requirement. Assume for this illustration that there are no management actions, no other earnings or capital changes, and that the stress affects resources and requirement exactly as stated. Post-stress resources are \(C-L\), while the post-stress requirement is \(R+\Delta R\).
Rearranging gives \(C-R\ge L+\Delta R\). Current compliance, \(C\ge R\), establishes only that \(C-R\ge 0\). It does not establish that current excess capital \(C-R\) is large enough to absorb the stress loss and any increase in the requirement. This is why a passing current result cannot, by itself, settle a forward-looking solvency question. The calculation is only an illustration: actual assessments must use appropriate definitions, time horizons, assumptions, and treatment of actions.
State the applicable requirement and the capital resources measured on the relevant prescribed basis. Do not substitute an internal estimate for a prescribed figure.
Specify the material risk, planned business change, or scenario that matters to the insurer, and identify the assumptions used to assess it.
Report whether the prescribed test is met and what the insurer concludes about its own risks and plans. One conclusion should not be presented as proof of the other.
Worked Example: A Hypothetical Catastrophe Stress
A hypothetical insurer reports \(C=\$1{,}200\) million and \(R=\$1{,}000\) million. Assume the applicable regulatory floor is 100%. For its own assessment, it considers a one-year catastrophe scenario that reduces capital by \(\$170\) million. In the same scenario, retained earnings add \(\$45\) million to resources, while the projected requirement rises by \(\$80\) million. Assume no other changes or management actions. Calculate the current and stressed ratios.
Method. First calculate the current ratio. Then project resources and the requirement separately; do not apply the loss only to the current ratio.
Current result. The current ratio is \(\$1{,}200/\$1{,}000=1.20\), or 120%. This is above the assumed 100% floor.
Stressed resources. Start with \(\$1{,}200\) million, subtract the \(\$170\) million loss, and add \(\$45\) million of retained earnings: \(\$1{,}200-\$170+\$45=\$1{,}075\) million.
Stressed requirement and ratio. The stressed requirement is \(\$1{,}000+\$80=\$1{,}080\) million. The ratio is \(\$1{,}075/\$1{,}080=0.995370\ldots\), or 99.5% when rounded to one decimal place. Resources are \(\$1{,}080-\$1{,}075=\$5\) million below the stressed requirement.
Conclusion and check. The insurer is above the assumed floor at the current measurement date, but the stated scenario produces a ratio below 100%. The arithmetic checks: the net reduction in resources is \(\$170-\$45=\$125\) million, so resources fall from \(\$1{,}200\) million to \(\$1{,}075\) million, while the requirement rises by \(\$80\) million. A common mistake is to subtract the loss but omit the earnings, or to leave the requirement unchanged. Both would misstate the scenario specified in the problem.
When Regulatory Compliance Alone Leaves a Concern
A prescribed requirement necessarily reflects a defined measurement approach. The insurer’s own assessment may identify a concern that is not fully expressed by the regulatory result, or that arises from the insurer’s particular circumstances. Examples include a concentration in one type of exposure, a planned change in business mix, a risk that develops over a longer planning horizon, or a stress that affects both capital resources and the requirement. These are reasons to make the insurer’s assessment explicit, not reasons to disregard the applicable regulatory test.
An ORSA conclusion need not be reduced to a single ratio. The insurer may use quantitative projections and scenarios alongside qualitative analysis of its material risks and business plans. Where an internal target is used, it should be identified as the insurer’s own planning measure and its basis explained. It should not be mislabeled as a regulatory requirement unless it actually is one.
Worked Example: A Concentration the Prescribed Result Does Not Resolve
A hypothetical insurer has \(\$1{,}250\) million of regulatory-basis capital and a \(\$1{,}000\) million requirement. Assume the prescribed current test is met when the ratio is at least 100%. The insurer has a large concentration in one coastal region. For an own-purpose scenario, it estimates a \(\$300\) million loss and \(\$40\) million of capital generation over the assessment period. It also projects a requirement of \(\$1{,}050\) million after the scenario. Assume no other changes or management actions. Calculate the current and scenario results, and identify the distinct concern.
Method. Evaluate current regulatory compliance first, then calculate scenario resources and compare them with the scenario requirement.
Current result. The current ratio is \(\$1{,}250/\$1{,}000=1.25\), or 125%. The insurer meets the assumed current floor.
Scenario resources. Resources after the loss and capital generation are \(\$1{,}250-\$300+\$40=\$990\) million.
Scenario comparison. The scenario requirement is \(\$1{,}050\) million. The ratio is \(\$990/\$1{,}050=0.942857\ldots\), or 94.3% when rounded to one decimal place. The shortfall is \(\$1{,}050-\$990=\$60\) million.
Conclusion and check. The current prescribed test is met, but the insurer’s stated scenario produces a shortfall against the scenario requirement. The scenario does not change the current result; it reveals a concern that the current result alone does not answer. The arithmetic checks because the net reduction in resources is \(\$300-\$40=\$260\) million, taking resources from \(\$1{,}250\) million to \(\$990\) million. A common mistake is to interpret the 125% current ratio as evidence that the concentration is adequately addressed. It says only that the current prescribed ratio is above the assumed floor.
Common Exam Traps
- Equating a regulatory pass with an ORSA conclusion. Compliance answers whether a prescribed test is met. It does not automatically establish that the insurer’s own assessment finds its strategy and material risks acceptable.
- Calling an internal target a regulatory minimum. Label each threshold by its source and purpose. A company target can be stricter than a prescribed floor without becoming a regulatory requirement.
- Mixing measurement dates or bases. A current regulatory ratio and a projected stress ratio are not interchangeable. State which capital resources and requirement are being compared, and when.
- Ignoring changes on one side of the comparison. A scenario may affect both resources and the requirement. Apply each stated change before calculating the resulting ratio.
- Assuming an ORSA is a substitute for compliance. The insurer’s own analysis complements the prescribed test; it does not remove the obligation to meet applicable requirements.
Check Your Understanding
For each hypothetical case, keep the prescribed compliance conclusion separate from the insurer’s own assessment. Unless stated otherwise, all amounts are in millions of dollars.
- An insurer has capital resources of 945 and a regulatory requirement of 900. Assume a 100% floor and an internal target of 112% of the same requirement. Calculate the current ratio and the amount by which resources exceed or fall short of the internal target. (Answer: 105.0%; compliant with the assumed floor, but 63 below the 1,008 internal target.)
- An insurer starts with resources of 1,500 and a requirement of 1,200. In a one-year scenario, resources lose 210 and gain 60 from earnings; the requirement rises by 10%. Calculate stressed resources, the stressed ratio, and the shortfall or excess against a 100% floor. (Answer: Resources 1,350; requirement 1,320; ratio 102.3%; 30 excess, so it remains above the assumed floor in the scenario.)
- A company currently has resources of 870 and a requirement of 750. Its own stress reduces resources by 140 and increases the requirement by 80. Calculate the current ratio, stressed ratio, and stressed shortfall or excess against a 100% floor. (Answer: Current ratio 116.0%; stressed resources 730 and requirement 830; stressed ratio 88.0%; shortfall 100.)
- A hypothetical insurer has current resources of 1,100 and a requirement of 1,000. In a planned scenario, a loss reduces resources by 180, earnings add 20, and an implementation cost reduces resources by a further 30. The requirement rises by 40. Calculate the current ratio and scenario ratio, then state whether the scenario passes an assumed 100% floor. (Answer: Current ratio 110.0%; scenario resources 910 and requirement 1,040; scenario ratio 87.5%, below the assumed floor by 130.)
