17.2 Rates, Forms, Solvency, and Guaranty Associations

The Three Regulatory Goals of Rates

State regulators review property and casualty rates against a three-part statutory standard drawn from the NAIC model: rates must be adequate, not excessive, and not unfairly discriminatory.

• Adequate — high enough to keep the insurer solvent and able to pay claims (protects the insurer and policyholders).
• Not excessive — not so high as to produce an unreasonable profit when a competitive market exists.
• Not unfairly discriminatory — risks with the same expected loss and expense must be charged the same; differences in price must reflect real differences in exposure.

Exam Key: Charging a driver with three at-fault accidents a higher auto premium is fair (risk-based) discrimination — it is legal and expected. Unfair discrimination is pricing on a factor unrelated to loss exposure (e.g., charging two identical risks different rates).

Rate Filing Systems

The method by which a new rate becomes usable is heavily tested. Learn the spectrum from most to least restrictive:

The phrase to memorize: Prior Approval = File, Approval, Use. Many states use a deemer clause — if the commissioner does not act within a set number of days (e.g., 30), the filing is deemed approved. Note that some lines (notably workers compensation in many states) are subject to prior approval even where competitive lines enjoy file-and-use, and inland marine classes are often exempt from filing altogether because they are individually rated.

Form Regulation and Advisory Organizations

Policy forms (the contract wording) are also filed and reviewed for compliance and readability. Most P&C insurers do not write their own forms from scratch; they use standardized forms from advisory organizations:

• ISO (Insurance Services Office) — develops standard P&C forms such as the HO-3 (HO 00 03) homeowners special form, the CPP commercial package policy, the CGL (CG 00 01) commercial general liability coverage form, and the CAdditional commercial auto forms (CA 00 01). Editions carry dates (e.g., the CGL 04 13 edition).
• AAIS (American Association of Insurance Services) — a competing advisory organization for forms and loss costs.
• NCCI (National Council on Compensation Insurance) — develops workers compensation rates, forms, and the experience rating plan in most states.

ISO files loss costs (the pure-premium portion); each insurer then adds its own loss-cost multiplier (LCM) for expenses and profit to reach a final rate.

Worked Example — Experience Modification Factor

Workers compensation premiums are adjusted by an experience modification factor (mod) that compares an employer's actual losses to expected losses for its class:

Mod = Actual Losses / Expected Losses

If an employer's expected losses are $100,000 and actual losses are $120,000, the mod = 120,000 / 100,000 = 1.20 (a debit — 20% surcharge). If actual losses were only $70,000, the mod = 0.70 (a credit — 30% discount).

Premium calculation: Manual premium x Experience mod = Modified premium.

Manual premium $50,000 x mod 1.20 = $60,000. The same employer with a 0.70 mod would pay $50,000 x 0.70 = $35,000. A mod of exactly 1.00 is average for the class. This is the most-tested numeric on the WC portion.

Solvency Regulation and the Guaranty Association

Protecting insurer solvency is the regulator's core job, because a rate that is too low threatens the insurer's ability to pay claims. Tools include:

• Financial examinations at least every 3-5 years.
• Risk-Based Capital (RBC) requirements — a formula-driven minimum capital level. Falling below RBC triggers escalating regulatory action: Company Action Level, Regulatory Action Level, Authorized Control Level, and Mandatory Control Level.
• Reserves — insurers must hold loss reserves and unearned premium reserves.

When an insurer becomes insolvent, the commissioner places it in rehabilitation or liquidation. Policyholder claims are then backstopped by the state's Property & Casualty Guaranty Association.

Exam Trap: Guaranty associations are funded by assessments on solvent admitted insurers — never by a state tax. Coverage applies only to admitted insurers; surplus lines (non-admitted) insurers are NOT covered. Per-claim caps (often ~$300,000, plus unearned-premium caps) apply.

Worked Example — Coinsurance Penalty

Property rating ties directly to the coinsurance clause, the most-tested property numeric. Coinsurance requires the insured to carry coverage equal to a stated percentage (commonly 80%) of the property's value, or share in any partial loss.

The formula:

Claim payment = (Carried / Required) x Loss − Deductible

Example: A building worth $500,000 with an 80% coinsurance clause requires $400,000 of coverage. The owner carries only $300,000. A fire causes a $100,000 loss with a $1,000 deductible.

• Required = 0.80 x $500,000 = $400,000
• Ratio = $300,000 / $400,000 = 0.75
• Payment = 0.75 x $100,000 = $75,000 − $1,000 = $74,000

The insured absorbs the $25,000 coinsurance penalty plus the deductible for being underinsured. Carrying the full $400,000 would have paid the loss in full (less the deductible).
