Why Own Funds Are Not All Equally Eligible
A solvency balance sheet compares the recognized value of an insurer’s assets with its liabilities. The excess of assets over liabilities represents a key source of financial resources, but it does not follow that every dollar of that excess can be used freely to meet a capital requirement. Some resources may be restricted, difficult to transfer, repayable soon, or available only if a future condition is met.
The task is therefore two-stage: first identify the own funds, then assess which amounts are eligible to cover the requirement. Quality is judged by the resources’ availability, permanence, subordination, and ability to absorb losses. The exact legal tests and quantitative limits depend on the applicable solvency regime. The examples below use explicitly stated hypothetical rules; they do not describe universal regulatory limits.
Four Qualities That Support Eligibility
The following questions help assess the quality of a resource. They are related, but they are not interchangeable: a resource can be permanent yet unavailable, or available today but unable to absorb losses when they occur.
- Availability: Can the insurer use the resource to meet losses or obligations when needed? Restrictions, pledges, ring-fencing, or legal barriers may prevent an amount from being available to the relevant insurer or fund.
- Permanence: Is the resource available over a sufficiently long period, or can its provider demand repayment or redemption soon? A short-term repayable instrument may be less dependable than permanent capital.
- Subordination: In a wind-up or insolvency, must the resource rank behind policyholder and other higher-priority claims? A claim that must be repaid ahead of policyholders is less capable of supporting them.
- Loss-absorption capacity: Can the resource bear losses when they arise, including while the insurer continues operating if the applicable standard requires that? A resource that only contributes value after a remote event may offer less immediate protection.
Assessment depends on the legal and economic terms, not just the instrument’s label. For example, calling an instrument “capital” does not establish that it is permanent or subordinated. Conversely, the terms of an instrument may support a qualifying classification even if its name is unfamiliar. Eligibility also depends on whose requirement is being covered: resources that cannot be transferred from a restricted fund or another legal entity may not be available to the entity facing the loss.
From Classification to Eligible Amount
A solvency regime may group own funds into quality categories, often called tiers. Higher-quality categories generally contain resources that are more available, permanent, subordinated, and capable of absorbing losses. Lower-quality categories may still count, but only up to stated limits. The classification must be made before applying those limits.
A useful calculation sequence is:
Determine whether it is already included in recognized own funds or is a separate, conditional resource.
Review restrictions, repayment terms, ranking, and the conditions under which losses can be absorbed.
Exclude amounts that fail a stated test, or reduce them if only part of the resource is available.
Use the stated caps for lower-quality categories and check any combined limits.
Report eligible own funds separately from the capital requirement and any excess or shortfall.
For a hypothetical regime with a Tier 2 cap \(c_2\), a Tier 3 cap \(c_3\), and a combined lower-tier cap \(c_{23}\), let \(F_1,F_2,F_3\) be the qualifying amounts available in each tier and \(C\) the capital requirement. The eligible lower-tier amounts \(E_2,E_3\) must satisfy:
If all Tier 1 funds qualify without a separate cap, total eligible own funds are \(F_1+E_2+E_3\). The lower-tier amounts cannot simply be added at their full face values: each category limit and the combined limit must hold at the same time.
Why the Cap Calculation Works
The cap calculation follows directly from the meaning of “eligible.” A resource cannot contribute more than the amount that actually qualifies, so \(E_j \le F_j\). If the regime permits a category to cover at most a fraction \(c_j\) of the capital requirement \(C\), it also requires \(E_j \le c_jC\). Both conditions must be satisfied; therefore, the category’s individual eligible amount cannot exceed the smaller of those two bounds.
If there is also a combined cap, meeting each individual cap is not enough. The sum of eligible amounts must satisfy \(E_2+E_3 \le c_{23}C\). For example, amounts individually below their separate caps may still exceed the combined cap. This is why a calculation must check the total after applying individual limits.
Worked Example: Separating Own Funds From Eligible Funds
A hypothetical insurer reports total recognized assets of $128 million and recognized liabilities of $100 million on its solvency balance sheet. The $28 million excess consists of $8 million of paid-up ordinary capital, $5 million of unrestricted retained earnings, $4 million of fully paid subordinated capital that meets the stated quality tests, and $11 million of surplus in a legally ring-fenced fund that cannot support the insurer’s general capital requirement. A separate $1 million callable commitment has been approved as an ancillary resource but is not included in the $28 million balance-sheet excess. How much is eligible before applying any tier caps?
Method. Reconcile the balance-sheet own funds, exclude the unavailable amount, and consider the separately approved commitment on its own terms.
First, the balance-sheet own funds are:
The components reconcile to that amount:
The ring-fenced $11 million is included in the reported own funds, but it cannot support the general requirement under the stated facts. The other balance-sheet components total \(8+5+4=17\) million and meet the stated availability and quality tests. The approved $1 million commitment is separate; adding it does not change the balance-sheet excess, but it may count as an ancillary resource under the hypothetical rules.
The answer is $18 million before tier caps, with $17 million from the balance-sheet own funds and $1 million from the approved ancillary commitment. The common mistake is to count all $28 million just because it is the balance-sheet excess. The correction is to test availability and distinguish balance-sheet own funds from separately approved resources.
Worked Example: Applying Individual and Combined Tier Caps
A hypothetical insurer has a capital requirement of $24 million. After quality and availability tests, it has $14 million in Tier 1, $9 million in Tier 2, and $6 million in Tier 3. The stated rules allow Tier 2 up to 50% of the requirement, Tier 3 up to 15%, and Tier 2 plus Tier 3 up to 50%. Calculate eligible own funds and the amount above the requirement.
Method. Apply the individual caps first, then check the combined cap.
The Tier 2 limit is \(0.50(24)=12\) million, so its eligible amount is \(\min(9,12)=9\) million. The Tier 3 individual limit is \(0.15(24)=3.6\) million, so the Tier 3 amount can initially be no more than $3.6 million. But \(9+3.6=12.6\) million exceeds the combined limit \(0.50(24)=12\) million. With Tier 2 at $9 million, Tier 3 must therefore be reduced to \(12-9=3\) million.
Total eligible own funds are \(14+9+3=26\) million. The amount above the capital requirement is \(26-24=2\) million. The result satisfies the Tier 3 individual cap because \(3 \le 3.6\), and the combined cap because \(9+3=12\). The common mistake is to stop after checking the individual caps and count $27.6 million; the correction is to enforce the combined cap as well.
Worked Example: Testing an Instrument’s Terms
Under a hypothetical framework, a paid-up instrument qualifies as Tier 2 only if it is subordinated to policyholder claims, cannot be repaid for at least three years, has no acceleration clause that defeats that restriction, and can absorb losses under the stated insolvency test. An insurer has $8 million of unrestricted qualifying Tier 1 funds, a $6 million note with a four-year non-repayable term, and a $2 million note with a two-year term. Both notes are subordinated and meet the loss-absorption test. The Tier 2 cap is $10 million, and the capital requirement is $20 million. Calculate eligible own funds.
Method. Apply every stated quality condition to each note before applying the cap.
The $6 million note is subordinated, has a four-year term, contains no stated acceleration feature, and meets the loss-absorption test. It therefore qualifies as Tier 2. The $2 million note is subordinated and loss-absorbing, but its two-year term is shorter than the required three years. It fails the permanence condition and is excluded. Thus the qualifying Tier 2 amount is $6 million, which is below the $10 million cap.
The eligible amount is $14 million. The common mistake is to classify both notes as Tier 2 because they are subordinated. The correction is to test all stated conditions: subordination alone does not establish permanence or eligibility.
Common Judgments and Exam Traps
Eligibility questions often turn on a small phrase in the instrument terms or in the stated rules. “Approved” does not necessarily mean unlimited: an approved resource may still be subject to a cap. “Subordinated” does not mean permanent. “Available to the group” does not necessarily mean transferable to the regulated insurer that needs the funds. A callable commitment is not the same as cash already received, and its treatment depends on whether it is approved and on the applicable conditions.
Keep the following distinctions explicit in a calculation:
- Recognized own funds versus eligible own funds: an amount may appear in the solvency balance-sheet excess and still be unavailable for the requirement being tested.
- Balance-sheet resources versus ancillary resources: do not add a contingent resource to the balance-sheet excess unless the stated accounting or solvency treatment says it is already included.
- Face amount versus qualifying amount: restrictions or instrument terms may mean that only part, or none, of a stated amount qualifies.
- Quality classification versus caps: classify first, then apply individual and combined limits. A category label does not guarantee that its full amount is eligible.

Use the rules stated in each question; limits are hypothetical and apply only to that question.
- A hypothetical insurer has a $30 million capital requirement, with $18 million Tier 1, $10 million Tier 2, and $7 million Tier 3. Tier 2 is capped at 50% of the requirement, Tier 3 at 10%, and the two tiers combined at 50%. What is the total eligible amount? (Answer: $31 million)
- A solvency balance sheet has assets of $76 million and liabilities of $66 million. The $10 million excess consists of $5 million unrestricted capital, $3 million unrestricted retained earnings, and $2 million unavailable ring-fenced surplus. A separate $1 million ancillary commitment is approved and eligible with no further cap. What amount is eligible before tier caps? (Answer: $9 million)
- A framework requires a Tier 2 note to be subordinated and have a non-repayable term of at least three years. The insurer holds a qualifying $8 million Tier 1 amount, a subordinated $6 million note with a four-year term, and a subordinated $4 million note with a two-year term. The Tier 2 cap is $7 million. What is eligible? (Answer: $14 million)
- A hypothetical requirement is $20 million. Available funds are $12 million Tier 1, $8 million Tier 2, and $5 million Tier 3. Tier 2 is capped at 40% of the requirement, Tier 3 at 10%, and Tier 2 plus Tier 3 at 40%. What is the total eligible amount? (Answer: $20 million)
- An insurer reports $15 million of own funds: $9 million unrestricted, permanent, loss-absorbing capital and $6 million of resources legally unavailable to the insurer facing the requirement. A separate $2 million commitment is not approved. With no tier caps, what amount is eligible? (Answer: $9 million)
