17.2 Rates, Forms, Solvency, and Guaranty Associations
Key Takeaways
- Rates must be ADEQUATE, NOT EXCESSIVE, and NOT UNFAIRLY DISCRIMINATORY; under Prior Approval the rate cannot be used until approved, while File-and-Use allows immediate use
- The coinsurance formula is (Carried / Required) x Loss − Deductible; underinsuring below the required percentage triggers a penalty (e.g., 75% recovery in the worked example)
- ACV = Replacement Cost − Depreciation; Replacement Cost coverage pays full repair/replace cost, often after repairs are completed
- Solvency tools include reserves, Risk-Based Capital (RBC), and financial exams every 3-5 years; private raters (A.M. Best, S&P, Moody's) grade carrier strength
- Guaranty associations pay claims of INSOLVENT ADMITTED insurers up to caps (commonly $300,000 P&C); surplus lines / non-admitted carriers are NOT covered and advertising the fund to sell is prohibited
Rate Regulation
A rate is the price per unit of exposure; the premium is the rate multiplied by the number of exposure units. State law requires that rates be adequate (enough to pay claims and expenses, so the insurer stays solvent), not excessive (not unreasonably high for the risk), and not unfairly discriminatory (risks with similar loss potential pay similar rates).
States use several rate-filing systems:
| System | How it works |
|---|---|
| Prior Approval | File the rate and wait for affirmative approval before use |
| File-and-Use | File, then use immediately (regulator can disapprove later) |
| Use-and-File | Use the rate, then file within a set period (e.g., 15-30 days) |
| Flex Rating | Free to change within a band (e.g., +/-10%); outside the band needs approval |
| Open Competition (No File) | Market sets rates; little or no filing |
Exam trap: under Prior Approval, an insurer may not use a new rate until the commissioner approves it (or a deemer period passes). Under File-and-Use, the insurer may use it the moment it is filed.
Worked Numeric: Personal Auto Split Limits
Split liability limits are written as three numbers, e.g., 100/300/50 (in thousands): $100,000 bodily injury per person, $300,000 bodily injury per accident, $50,000 property damage. Suppose an at-fault insured injures three people for $80,000, $120,000, and $60,000 in bodily injury. The per-person cap of $100,000 reduces the $120,000 claim to $100,000. Paid BI = $80,000 + $100,000 + $60,000 = $240,000, which is under the $300,000 per-accident cap, so all three are paid in full to the per-person limit. The insured personally owes the $20,000 excess on the second claim.
Coinsurance, ACV, and Form Filing
Most property forms—including the ISO Commercial Property Building and Personal Property Coverage Form (CP 00 10)—carry an 80% coinsurance clause. If the insured carries less than the required percentage of value, the loss payment is reduced by the coinsurance formula:
Payment = (Limit Carried / Limit Required) x Loss − Deductible, capped at the policy limit.
Worked example. A building is worth $500,000. The 80% coinsurance requirement is $400,000. The insured carries only $300,000. A fire causes a $200,000 loss with a $1,000 deductible.
- Did-carry / should-carry = $300,000 / $400,000 = 0.75
- 0.75 x $200,000 = $150,000; minus $1,000 deductible = $149,000 paid
- The insured absorbs the remaining $51,000 as a coinsurance penalty plus deductible.
Had the insured carried the full $400,000, the formula ratio would be 1.0 and the insurer would pay the loss in full less the deductible ($199,000). Carrying more than required does not increase recovery beyond the actual loss. This is why agents stress maintaining values to the coinsurance percentage—an agreed value or inflation guard endorsement can suspend or soften the coinsurance penalty.
ACV (Actual Cash Value) = Replacement Cost − Depreciation. A 10-year-old roof with a 20-year life that costs $12,000 to replace has depreciated 50%, so ACV = $6,000. Replacement Cost coverage pays the full $12,000 (often after repairs are made).
Form Approval and Readability
Policy forms are also filed with the department. Many states impose prior approval of forms and plain-language / readability standards (e.g., a Flesch reading-ease minimum) so consumers can understand the contract.
Solvency Regulation
Regulators protect policyholders by ensuring insurers can pay claims. Tools include:
- Reserves: insurers must hold loss reserves and unearned premium reserves.
- Risk-Based Capital (RBC): a formula sets minimum capital based on the insurer's risk profile; falling below RBC triggers regulatory action levels.
- Financial examinations: typically every 3-5 years.
- NAIC Financial Analysis and the IRIS ratios for early warning.
The NAIC publishes a Financial Strength framework, while private raters (A.M. Best, S&P, Moody's) grade carriers (e.g., Best's A++ to F).
When RBC or examinations reveal trouble, the commissioner can escalate from supervision to rehabilitation (an attempt to fix and return the insurer to the market) and finally liquidation (winding up the insolvent insurer). The guaranty association is triggered at the liquidation stage.
Guaranty Associations
When a licensed insurer becomes insolvent, the state Guaranty Association pays covered claims up to statutory caps. Key points for the exam:
- Membership is mandatory for admitted insurers; assessments on solvent insurers fund the payouts.
- Coverage applies to policies of admitted (licensed) insurers only—surplus lines / non-admitted carriers are generally NOT protected.
- Property-casualty guaranty funds commonly cap a claim at $300,000 (caps vary by state and line); workers compensation claims are often paid without that cap.
- Funds are a safety net, not a marketing point—advertising guaranty-fund protection to sell a policy is an unfair trade practice in most states.
Trap: Surplus lines policies (placed with non-admitted carriers for hard-to-place risks) are NOT covered by the guaranty association. Always check admitted vs. non-admitted.
How Assessments Work
When the fund pays an insolvent insurer's claims, it assesses the remaining solvent insurers writing the same line in that state, usually in proportion to their market share (premium written). Many states let insurers recoup these assessments through a premium surcharge or a tax offset over time, so the ultimate cost can flow back to policyholders. There is typically an annual assessment cap (often around 2% of an insurer's premium) to prevent a single insolvency from threatening solvent carriers.
A building valued at $500,000 has an 80% coinsurance clause. The insured carries $300,000 of coverage and suffers a $200,000 fire loss with a $1,000 deductible. How much does the insurer pay?
