Capital Raising Versus Risk Transfer

Two Different Ways to Strengthen Financial Resilience

An insurer facing a capital shortfall may raise funds, transfer some risk, or consider both. These choices can produce similar-looking solvency ratios in one calculation, but they work differently. Capital raising adds financing capacity; it does not, by itself, reduce the losses the insurer bears. Risk transfer reduces specified losses, usually in return for a premium, but introduces contract terms, counterparty exposure, and potentially a lower capital requirement.

The comparison should therefore trace each option through its costs, the balance sheet, the stress loss, and the capital requirement. A single headline figure—such as the amount raised or the amount of reinsurance purchased—does not capture those effects. The framework here is aligned with the CAS Exam 9 (Risk Management for Actuaries) syllabus.

Definition: Let $A$ denote available capital and $K$ required capital. The solvency ratio used in this tutorial is $A/K$, where $K>0$. A higher ratio indicates more available capital relative to the stated requirement, but comparisons are meaningful only when the capital definitions and measurement basis are consistent. For an equity issue of gross amount $G$ with issuance-cost rate $c$, net proceeds are $G(1-c)$. For a specified stress loss $L$, a transfer that pays $R$ in that stress leaves retained loss $L-R$, provided $0\leq R\leq L$.

What the Alternatives Change

An ordinary equity issue brings cash into the insurer, less underwriting, legal, and other issuance costs. The proceeds increase available capital under the simplified balance-sheet assumptions used in a calculation. They do not change the underlying loss distribution merely because new shares have been issued. Existing owners also hold a smaller fraction of the company if new shares are issued.

Contingent capital is financing that becomes available only if specified contractual conditions are met. Examples include a committed facility that can be drawn after a defined event or a security that converts under stated terms. Its value depends on whether the trigger is met, how quickly funds arrive, whether the provider can perform, and what costs or dilution apply. A commitment that is unavailable in the stress of interest is not usable stress capital.

Reinsurance instead transfers contractual losses to a reinsurer. A premium reduces capital, while recoveries reduce the insurer’s retained loss when the contract responds. A capital model may also recognize lower required capital, but that recognition must be stated rather than assumed. Recoveries may be uncertain, delayed, limited by exclusions, or exposed to counterparty default.

Decision feature	Equity or contingent capital	Risk transfer
Immediate balance-sheet effect	Net cash proceeds add financing, subject to issue or draw costs.	Premium or other consideration uses funds; recoveries depend on covered losses.
Stress loss borne by insurer	Unchanged by the capital raising itself.	Reduced only for losses that the contract covers and pays.
Ownership or contractual effects	Equity can dilute existing ownership; contingent terms can restrict availability.	Contract limits, exclusions, counterparty exposure, and claims timing matter.
Capital requirement	May remain unchanged in a simplified comparison.	May fall if the model recognizes the transfer; the amount must be specified.

Calculating the Main Effects

For an equity issue, if $A_0$ is initial available capital, the simplified post-issue amount is $A_0+G(1-c)$. If required capital remains $K$, the resulting solvency ratio is $[A_0+G(1-c)]/K$. These expressions assume the stated net proceeds qualify as available capital, that no other balance-sheet items change, and that the issue does not alter $K$. A real assessment must use the applicable capital definitions and recognize any other effects.

If there are $N_0$ existing shares and $N_1$ new shares, the new investors’ ownership fraction immediately after the issue is $N_1/(N_0+N_1)$. If shares are sold at issue price $p$ to raise gross amount $G$, then $N_1=G/p$. This fraction describes ownership dilution; it is not the issuance-cost rate. The issue costs are borne by the company and reduce the net value added.

Under a specified stress, a simplified available-capital calculation for a transfer is initial capital less the premium and the retained stress loss. If the post-transfer required capital is $K_T$, the stress ratio is $[A_0-P-(L-R)]/K_T$, where $P$ is the premium. This form assumes the recovery $R$ is fully collectible and available in the stress period; use a lower recovery if counterparty or timing adjustments are specified.

Derivation: A loss of $L$ reduces the insurer’s resources by $L$. If the contract pays $R$ toward that loss, the insurer bears only $L-R$. Paying premium $P$ has already reduced resources by $P$. Thus resources after the premium and stress are $A_0-P-(L-R)$. The transfer changes the capital outcome through the premium, the covered recovery, and any stated change in required capital—not by adding $R$ as free capital while leaving the full loss in place.

Worked Example: Equity Proceeds, Solvency, and Share Dilution

A hypothetical insurer has available capital of $86.000 million and required capital of $100.000 million. It issues $18.000 million of ordinary equity. Issuance costs are 5% of gross proceeds. Before the issue, the company’s equity value is $72.000 million, represented by 12.000 million shares. The new shares are sold at the pre-issue value per share. Calculate net proceeds, post-issue solvency, and the new investors’ ownership fraction.

Method. First deduct issuance costs from gross proceeds. Then calculate the solvency ratio using net, not gross, proceeds. Finally use the share price to determine the number of new shares.

The issuance cost is $0.05\times \$18.000=\$0.900$ million, so net proceeds are $\$18.000-\$0.900=\$17.100$ million. Post-issue available capital is $\$86.000+\$17.100=\$103.100$ million. With required capital unchanged at $100.000 million, the solvency ratio is $103.100/100.000=1.031$, or 103.1%.

The pre-issue share price is $\$72.000\text{ million}/12.000\text{ million shares}=\$6.00$ per share. The issue creates $\$18.000\text{ million}/\$6.00=3.000$ million new shares. Total shares after issue are $12.000+3.000=15.000$ million. The new investors own $3.000/15.000=0.200$, or 20.0%.

Check. The costs are $0.900 million and the insurer retains $17.100 million of the $18.000 million gross issue. The share count increases by 25% relative to the old count, while the new investors’ fraction of the enlarged total is 20.0%. The common mistake avoided is adding gross proceeds to capital or confusing share-count growth with the new investors’ ownership fraction.

Compare the Same Stress, Not Just the Same Funding Amount

A useful comparison specifies the same stress loss and makes each option’s cost and capital treatment explicit. In particular, a transfer’s reduction in required capital should not be inferred from its recovery amount. Required capital is a model output that may recognize the risk reduction; it is not the same thing as cash recovery.

Worked Example: Equity or Reinsurance Under a Specified Stress

A hypothetical insurer has available capital of $80.000 million and required capital of $100.000 million. Consider two separate options. Option E is an equity issue of $25.000 million with 4% costs; assume required capital remains $100.000 million. Option R is reinsurance costing a $5.000 million premium. A specified stress loss is $30.000 million, and the contract pays $20.000 million in that stress. The capital model recognizes the reinsurance by setting post-transfer required capital at $70.000 million. Calculate each option’s stressed available capital and solvency ratio, and compare with no action.

Method. Apply issue costs to equity proceeds. For reinsurance, deduct both the premium and the retained stress loss. Use the required capital given for each option.

With no action, stressed available capital is $\$80.000-\$30.000=\$50.000$ million. The ratio is $\$50.000/\$100.000=50.0\%$.

For Option E, issuance costs are $0.04\times \$25.000=\$1.000$ million, so net proceeds are $\$25.000-\$1.000=\$24.000$ million. After the $30.000 million stress loss, available capital is $\$80.000+\$24.000-\$30.000=\$74.000$ million. The ratio is $\$74.000/\$100.000=74.0\%$.

For Option R, retained stress loss is $\$30.000-\$20.000=\$10.000$ million. Stressed available capital is $\$80.000-\$5.000-\$10.000=\$65.000$ million. Using the specified post-transfer requirement, the ratio is $\$65.000/\$70.000=92.8571\%$, or 92.9% to one decimal place.

Check. Reinsurance has lower stressed available capital than the equity option ($65.000 million versus $74.000 million), but its stated required capital is also lower. Its solvency ratio is therefore higher in this example. This is not a general ranking: it depends on the stated recovery, premium, and capital-model recognition. The common mistake avoided is comparing the $20.000 million recovery directly with $24.000 million of equity proceeds while ignoring the premium, retained loss, and different required-capital amounts.

Contingent Capital: Availability Is Part of the Benefit

A committed amount should not automatically be counted as available capital. Evaluate the contract in the scenario in which the funds are needed: check the trigger, the draw period, transaction costs, any limits on use, and whether the provider can supply the funds. A trigger based on an index or another measured event can fail to align with the insurer’s actual loss. That basis risk can leave the insurer with a severe loss and no draw.

Even if funds are drawn, contingent capital is not necessarily risk transfer. A facility that provides an equity infusion increases resources when drawn, but the underlying insured loss is still borne by the insurer. The commitment fee is a cost of maintaining access; transaction costs reduce proceeds at drawdown. If the arrangement issues shares, its contractual issue price and resulting dilution should also be examined.

Worked Example: Contingent Capital With a Trigger and Draw Cost

A hypothetical insurer begins with available capital of $92.000 million and required capital of $100.000 million. It has a $20.000 million contingent equity facility. The annual commitment fee is $0.600 million, the facility is drawn at year-end if its trigger is met, and draw costs equal 2% of the amount drawn. A stress loss of $22.000 million occurs in the year. Calculate stressed available capital and the ratio if the trigger is met, and if it is not met. Assume the fee is paid in either case and required capital is unchanged.

Method. Deduct the fee in both cases. If the trigger is met, add the net draw proceeds; if it is not, add nothing. Deduct the full stress loss in either case because the facility does not transfer that loss.

If the trigger is met, draw costs are $0.02\times \$20.000=\$0.400$ million, giving net proceeds of $\$20.000-\$0.400=\$19.600$ million. Stressed available capital is $\$92.000-\$0.600-\$22.000+\$19.600=\$89.000$ million. The ratio is $\$89.000/\$100.000=89.0\%$.

If the trigger is not met, proceeds are zero. Stressed available capital is $\$92.000-\$0.600-\$22.000=\$69.400$ million. The ratio is $\$69.400/\$100.000=69.4\%$.

Check. The difference between the two outcomes is exactly the $19.600 million net draw. Neither outcome eliminates the $22.000 million loss. The common mistake avoided is treating the full $20.000 million commitment as certain capital before checking the trigger and draw cost.

Decision Considerations and Common Traps

The numerical comparison should be accompanied by a practical assessment of flexibility. An equity issue may provide unrestricted and durable funding, but market access, pricing, transaction timing, and dilution can constrain it. Contingent capital can preserve flexibility until needed, but its trigger and draw terms may be restrictive. Reinsurance can directly reduce retained covered losses and may reduce required capital, but it creates a premium burden and dependence on contract response and counterparty performance.

The relevant comparison is not always a choice of one alternative. An insurer might raise capital to strengthen its general buffer and transfer a specific tail exposure. The analysis should identify which risk is addressed by each instrument, avoid counting the same benefit twice, and show how the result changes if a recovery is delayed, reduced, or unavailable.

Using gross instead of net proceeds. Deduct issue or draw costs before adding funds to available capital.
Equating dilution with issuance cost. Dilution is a change in ownership fraction; issuance costs are expenses that reduce net proceeds.
Crediting a transfer without subtracting its premium. A recovery is not free funding; reflect both the premium and the retained loss.
Assuming every transfer reduces required capital by its recovery amount. Use the post-transfer requirement supplied by the model or explicitly state the assumption.
Counting a contingent commitment before its trigger is satisfied. Test whether it is accessible in the scenario being evaluated.

Key takeaway: Capital raising increases the resources available to absorb losses; risk transfer changes which losses the insurer retains. A defensible comparison shows net costs, stress-period availability, residual exposure, dilution where relevant, and the required-capital basis for every solvency ratio.

Check Your Understanding

For each problem, state the calculation basis and check whether the stated capital requirement changes.

A hypothetical insurer has available capital of $68.000 million and required capital of $80.000 million. It issues $12.000 million of equity at 3% costs. Required capital is unchanged. Find net proceeds, post-issue available capital, and the solvency ratio. (Answer: Net proceeds $11.640 million; available capital $79.640 million; solvency ratio 99.55%.)
A company has 9.000 million existing shares and a pre-issue equity value of $45.000 million. It issues $15.000 million of shares at the pre-issue share price. Find the issue price, number of new shares, and new investors’ ownership fraction. (Answer: $5.00 per share; 3.000 million new shares; 25.0% ownership.)
Available capital is $110.000 million. Reinsurance costs a $3.000 million premium and pays $12.000 million against a $20.000 million stress loss. Post-transfer required capital is $105.000 million. Find stressed available capital and the solvency ratio. (Answer: $99.000 million; 94.3%.)
An insurer has available capital of $70.000 million and required capital of $90.000 million. A $10.000 million contingent facility has a 1% draw cost and a $0.400 million fee that is paid whether or not the trigger is met. A stress loss of $18.000 million occurs. Find the stressed ratio if the trigger is met and if it is not met. (Answer: Trigger met: available capital $61.500 million and ratio 68.3%; trigger not met: available capital $51.600 million and ratio 57.3%.)
An insurer has available capital of $95.000 million and required capital of $100.000 million. Under Option E, it issues $10.000 million of equity with 5% costs and required capital remains $100.000 million. Under Option R, it pays a $4.000 million premium, recovers $14.000 million against a $22.000 million stress loss, and has post-transfer required capital of $90.000 million. Find each stressed solvency ratio and identify which is higher under these assumptions. (Answer: Option E: $82.500 million stressed available capital and 82.5%; Option R: $83.000 million stressed available capital and 92.2%; Option R has the higher ratio under the stated assumptions.)
