Why Board Challenge Matters
An ORSA is an insurer-owned assessment of its current and prospective risks and solvency. The board’s role is not to reproduce every calculation or take over the work of management. It is to determine whether the assessment is credible, sufficiently connected to the insurer’s risk profile and strategy, and useful for decisions. Approval should therefore reflect informed judgment about the conclusions and their limitations—not simply agreement that a document has been produced.
Effective challenge is specific. Directors ask what an assumption means, why it is suitable for this insurer, what changes if it is wrong, and what decision follows from the result. A question such as “Did we include a severe claims scenario?” is a starting point. A stronger question asks how the scenario was selected, which risks it combines, how its results compare with available capital, and whether the proposed response remains feasible under the same conditions.
Challenge does not require directors to reject an assessment or to select different assumptions merely because they are more severe. It requires a credible basis for the assumptions, visibility into their effects, and a reasoned account of what management would do if adverse results emerged. An ORSA that reports a favorable result but cannot explain its sensitivities or limitations gives the board less basis for approval.
A Practical Structure for Challenge
A useful discussion follows the reasoning from the insurer’s circumstances to its decisions. The board can test whether the assessment answers five connected questions.
Confirm the decision purpose, time horizon, material risks, and entities or activities in scope. Ask what has been excluded and why.
Identify material assumptions about the insurer’s future business, losses, asset values, and available responses. Ask why they fit the insurer’s own risk profile.
Ask how adverse scenarios and sensitivities change the solvency conclusion. Distinguish a quantified result from a narrative assertion that the insurer could respond.
Relate available resources to the assessed need, explain any shortfall or margin, and identify uncertainty that could change the conclusion.
Test whether proposed actions are timely, within management’s control, and realistically effective under the scenario that prompted them.
The chain matters because a result is only as useful as the reasoning behind it. If a modeled stress produces a surplus, directors should ask whether the stress includes the risks that could plausibly occur together. If the surplus depends on a management action, the board should ask whether the action is available in that scenario, how much benefit is expected, and what it costs.
Assumptions, Scope, and Solvency Implications
Assumptions are not merely technical settings. They express a view about how the insurer’s business and risk environment may develop. Board questions should focus on assumptions that could materially change the conclusion, rather than treating every input as equally important. Examples include the pace and mix of planned growth, loss experience, asset market conditions, or the availability of a proposed response.
For each important assumption, directors can ask management to explain its rationale, the evidence or judgment supporting it, and the result of a reasonable alternative. A sensitivity is informative only when its change is clear: what was altered, what was held constant, and how the result moved. A sensitivity is not automatically a complete adverse scenario; several risks may interact, and a single-input change may not capture that interaction.
Scope also deserves explicit attention. A board should understand which material risks, operations, and entities are included, how the assessment treats relevant dependencies, and whether exclusions could affect the conclusion. Consolidated totals can obscure where resources are held or whether they can support obligations elsewhere. A favorable aggregate number is not, by itself, proof that every part of the organization can withstand stress.
The board should then connect results to decisions without confusing an ORSA conclusion with a point-in-time capital measure or a regulatory requirement. A result can inform strategy and capital management while still having uncertainty and limitations. Directors should be able to state what the result means for the insurer, which conditions would make it change, and what monitoring or action is proposed.
Worked Example: Challenging a Stress Result and Its Assumptions
A hypothetical insurer reports $150 million of available resources and an assessed need of $132 million under its central view. A downside scenario reduces resources by $14 million from claims and $9 million from asset losses. Management proposes an action expected to add $8 million of gross benefit if fully effective, but the board judges that only 75% of that benefit is credible in this scenario; implementation costs $2 million. Determine the resulting resources, headroom, and a focused board challenge.
Method. Calculate the stress result from the stated central resources, subtract the scenario losses, then add only the expected achievable portion of the action and subtract its cost. Headroom is resources after these changes minus assessed need.
First, the action’s scenario-adjusted benefit is \(0.75 \times 8 = 6\) million dollars. Resources after the stress and action are:
The resulting headroom is:
The scenario therefore leaves resources $1 million below assessed need, even after crediting the action at the stated achievable level. A useful board challenge is to ask why the 75% effectiveness estimate is credible under the same adverse conditions, when the action could be implemented, and whether the shortfall changes the insurer’s intended response.
Check. The net resource change is \(-14-9+6-2=-19\) million, and \(150-19=131\) million. Subtracting the $132 million need gives the same $1 million shortfall. The common mistake is to credit the full $8 million benefit despite the stated 75% effectiveness; doing so overstates resources by $2 million.
Deriving the Headroom Test
A simple headroom calculation helps directors keep assumptions and proposed actions visible. Let \(R\) be resources before the stress, \(N\) the assessed need, \(L\) the stress-related reduction in resources, \(B\) the action’s gross benefit if fully effective, \(q\) the proportion of that benefit expected to be achieved, and \(C\) the action’s cost. The calculation assumes these quantities are measured on a consistent basis and that the stated effects can be added or subtracted as specified.
Here \(H_0\) is initial headroom. After the stress and action, resources are \(R-L+qB-C\). Subtracting the assessed need gives:
This follows directly by grouping \(R-N\), which is \(H_0\). The expression shows why a proposed action should not be treated as a guaranteed benefit: its contribution is \(qB\), not \(B\), and its cost still reduces resources. It also shows the limits of this simple calculation. It does not model timing, feedback between risks, or changing need unless those effects are separately included in the inputs. Directors should not treat the formula as a substitute for understanding the scenario.
Worked Example: Testing a Proposed Management Action
In a hypothetical stress, an insurer has $120 million of available resources against a $114 million assessed need. A proposed action has a gross benefit of $10 million if fully achieved and costs $2 million. The board considers 60% of the gross benefit achievable in the stress. Calculate headroom after the action and identify the decision-relevant question.
Method. Calculate initial headroom, then add the achievable benefit and subtract the cost. Initial headroom is \(120-114=6\) million dollars. The achievable benefit is \(0.60 \times 10=6\) million dollars. Net improvement from the action is \(6-2=4\) million dollars.
Resources after the action are \(120+6-2=124\) million dollars. Therefore:
The action leaves $10 million of headroom, an increase of $4 million from the initial $6 million. The board should ask what evidence supports achieving 60% of the benefit in the stress, whether the action can be completed in time, and whether its cost is already reflected elsewhere in the assessment.
Check. Using the headroom identity gives \(6+(0.60 \times 10)-2=10\) million dollars, agreeing with the resource calculation. The common mistake is to stop at the $6 million achievable benefit and omit the $2 million cost, or to miscalculate the result as zero. Neither is correct: \(120+6-2-114=10\).
Testing Scope and the Meaning of Aggregate Results
A board should ask whether the assessment’s boundary is appropriate for the decisions it supports. This includes understanding which entities and material activities are represented, whether important risks are omitted, and whether the aggregate conclusion hides constraints on moving resources. The following example illustrates why a consolidated surplus alone can be incomplete.
Worked Example: Challenging an Aggregate Surplus
A hypothetical group reports resources of $44 million in Entity A and $29 million in Entity B. Their respective assessed needs are $38 million and $32 million. The report shows total resources of $73 million against total need of $70 million. However, of Entity A’s surplus, only $2 million can be transferred to Entity B in the scenario; the remaining $4 million is unavailable to support B. Determine the aggregate margin and whether the group total demonstrates that both entities meet their needs.
Method. First calculate each entity’s position and the aggregate position. Then apply the stated transfer constraint to assess whether the surplus can support the entity in deficit.
Entity A has \(44-38=6\) million dollars of surplus. Entity B has \(29-32=-3\) million dollars, a $3 million deficit. In aggregate, resources exceed need by \(73-70=3\) million dollars.
Only $2 million can be transferred from A to B in the scenario. B’s remaining deficit is therefore \(3-2=1\) million dollars. The group has a positive $3 million aggregate margin, but that total does not demonstrate that each entity can meet its need under the stated transfer constraint.
Check. After the transfer, A retains \(6-2=4\) million dollars of surplus and B remains $1 million below need. Together those positions sum to \(4-1=3\) million dollars, matching the aggregate margin. The common mistake is to infer that the positive aggregate margin is fully available wherever needed.
The board’s follow-up should be proportionate to the assessment’s purpose. It might ask whether the boundary matches the decision being made, what the transfer constraint represents, and how the result would change if the constraint worsened. The point is not to assume a particular legal or operational arrangement; it is to test whether the reported conclusion follows from the resources that are actually available in the scenario.
Common Traps in Board Review
- Approving the document rather than the reasoning. A completed report does not establish that its assumptions, scope, or conclusions are adequate.
- Treating a central estimate as certainty. Ask which assumptions matter most and how plausible alternatives affect the conclusion.
- Crediting a proposed action at its full stated benefit. Test effectiveness, timing, feasibility, and cost under the scenario in which the action is needed.
- Reading aggregate resources as universally available. Ask whether the assessment accounts for constraints that matter to the entities or activities in scope.
- Accepting a stress result without its decision implication. Ask what changes in capital management, risk-taking, or monitoring if the result is adverse.
- Confusing challenge with choosing model inputs. Directors should understand and test the rationale; challenge does not mean selecting arbitrary assumptions or directing every technical judgment.
Check Your Understanding
For each hypothetical case, calculate the requested result and consider what a director should challenge.
- An insurer has $210 million of resources and a $194 million assessed need. A stress reduces resources by $11 million from claims and $8 million from market losses. A response adds $6 million if fully effective, but only 50% is expected to be achieved; it costs $1 million. What is headroom after the response? (Answer: \(210-11-8+(0.50\times6)-1-194=-1\), so there is a $1 million shortfall.)
- A hypothetical insurer has $75 million of resources against a $70 million need. A downside scenario reduces resources by $9 million. A proposed action has a $5 million gross benefit, of which 80% is expected to be achieved, and costs $1.5 million. What is the resulting headroom? (Answer: \(75-9+(0.80\times5)-1.5-70=-1.5\), so there is a $1.5 million shortfall.)
- Entity A has resources of $44 million and need of $38 million. Entity B has resources of $29 million and need of $32 million. Only $2 million of A’s surplus can be transferred to B in the stress. What is the aggregate margin, and what is B’s remaining deficit after the transfer? (Answer: aggregate margin \(44+29-38-32=3\) million dollars; B’s remaining deficit is \(32-(29+2)=1\) million dollars.)
- A stress result shows $18 million of headroom, but the result assumes planned growth is achieved without increasing expenses and assumes a proposed risk response is fully effective. State two focused board questions that test the assumptions and the decision implication. (Answer: Ask what evidence supports growth without higher expenses and how the result changes if expenses rise; ask how feasible full effectiveness is under stress and what action follows if the achievable benefit is lower.)
- A group’s total resources exceed total assessed need by $5 million, but the report does not explain whether resources can move between entities or whether all material activities are included. What two limitations should the board clarify before treating the result as a sufficient group conclusion? (Answer: Clarify the scope and any omitted material entities or activities; clarify transferability and whether resources are available where the assessed need arises.)
