17.2 Rates, Forms, Solvency, and Guaranty Associations

Rate Regulation Standards

Every state requires that rates meet three statutory standards. A rate must not be:

• Inadequate — too low to keep the insurer solvent (this is why a rate can be disapproved for being too cheap).
• Excessive — unreasonably high relative to expected losses and expenses.
• Unfairly discriminatory — charging different rates to insureds of the same risk class and expected loss.

Note the trap: rates may legally differ between insureds when the underlying risk differs (a 19-year-old driver vs. a 45-year-old). Discrimination is only unfair when two insureds of the same class and hazard pay different rates.

Rate-Filing Systems

States use several filing methods. Memorize these for the exam:

The most heavily tested distinction is prior approval (wait) versus file-and-use (use immediately). Advisory organizations like ISO file prospective loss costs; each insurer adds its own expense and profit loading multiplier to reach a final rate.

Worked Rate Math: Loss Ratio & Pure Premium

Underwriting profitability turns on the loss ratio:

Loss Ratio = Incurred Losses ÷ Earned Premium

If an insurer pays $650,000 in losses on $1,000,000 of earned premium, the loss ratio is 65%. Add a 30% expense ratio and the combined ratio is 95%—an underwriting profit of 5 cents per premium dollar. A combined ratio above 100% means an underwriting loss (covered only by investment income).

The pure premium method builds a rate from losses alone: Pure Premium = Total Losses ÷ Number of Exposure Units. If 10,000 cars produce $4,500,000 of losses, the pure premium is $450 per car. Dividing by the permissible loss ratio (e.g., 1 - 0.30 expense = 0.70) grosses it up to a $643 gross rate.

A second exam favorite is the experience modification factor (e-mod) used in workers' compensation. The e-mod compares an employer's actual losses to the expected losses for its class. A mod of 1.00 is average; a mod of 0.85 earns a 15% credit (a $20,000 manual premium becomes $17,000), while a mod of 1.20 is a 20% debit ($20,000 becomes $24,000). The mod is the engine of experience rating—it rewards safer-than-average employers and surcharges riskier ones.

Policy Forms & Reading the Edition Date

Most personal and commercial property-casualty policies use standardized ISO forms. Forms must be filed and approved so the commissioner can confirm they are not deceptive and meet minimum coverage. High-yield form numbers:

The edition date printed on a form (e.g., CG 00 01 04 13 = April 2013) tells the producer which version applies; coverage interpretations can change between editions, so the in-force edition controls a claim.

Solvency Surveillance

Because McCarran-Ferguson makes solvency a state job, commissioners monitor insurers continuously. Key tools:

• Statutory accounting (SAP) — conservative accounting that values most assets at the lower of cost/market and excludes non-admitted assets, producing a cautious surplus figure.
• IRIS ratios — a set of financial ratios flagging insurers for closer review.
• Financial examinations — on-site exams typically every 3-5 years.

Risk-Based Capital (RBC) is an NAIC formula setting minimum capital by the insurer's risk profile. As surplus falls below RBC thresholds, regulators move through escalating action levels: Company Action, Regulatory Action, Authorized Control, and Mandatory Control (at which point the commissioner must seize the insurer).

Guaranty Associations

When an admitted insurer becomes insolvent, the state guaranty association pays covered claims up to statutory limits (commonly $300,000 per claim for property-casualty, varying by state). Critical exam points:

1. Membership is mandatory for every admitted insurer in the state; solvent insurers are assessed to fund the shortfall.
2. The assessment is generally post-insolvency (paid after a company fails) and insurers may recoup it through premium-tax credits.
3. Only policyholders of admitted insurers are protected—surplus-lines/non-admitted policyholders are not covered.

Exam Key: Guaranty associations are funded by ASSESSING the surviving solvent insurers AFTER an insolvency—never by a standing pre-paid fund, and producers may NOT advertise guaranty-association protection as an inducement to buy.

The Three Rate Standards

State rate regulation enforces three statutory standards the exam states verbatim: rates must be adequate (enough to keep the insurer solvent and pay claims), not excessive (not unreasonably high for the coverage), and not unfairly discriminatory (no different rates for risks of the same class and hazard). A rate that is too low threatens solvency; too high gouges consumers; discriminatory rating among like risks is prohibited. Every rate-filing question turns on one of these three words.

Rate-Filing Systems Compared

States use several filing approaches:

• Prior approval — the insurer must wait for the department's approval before using a rate.
• File-and-use — the insurer may use the rate immediately upon filing.
• Use-and-file — the insurer uses the rate and files shortly after.
• Flex (modified prior approval) — small changes within a band are automatic; larger ones need approval.
• Open competition (no-file) — market forces set rates with minimal filing.

A stem describing an insurer that implemented a new rate before the regulator reviewed it is file-and-use (or use-and-file), not prior approval.

Worked Rate Math — Loss Ratio and Pure Premium

The loss ratio = incurred losses ÷ earned premium. If losses are $650,000 on $1,000,000 earned premium, the loss ratio is 65%. Compared to a permissible (target) loss ratio of, say, 60%, the actual 65% signals the rate is inadequate and an increase is indicated. The pure premium method sets rate from losses ÷ exposure units, then loads for expenses and profit: pure premium ÷ (1 − expense ratio) yields the gross rate. The exam expects you to compute a loss ratio and judge adequacy.

Forms, Solvency, and Guaranty Associations

Most states require policy-form approval to ensure forms are not deceptive and meet minimum statutory provisions; the edition date identifies the form version. Solvency surveillance uses financial examinations, RBC (risk-based capital) thresholds, IRIS ratios, and reserve requirements; failing insurers go into rehabilitation or liquidation. When a member insurer becomes insolvent, the state guaranty association pays covered claims up to statutory caps and is funded by post-insolvency assessments on solvent insurers in the state.

The exam tests that guaranty funds protect policyholders of admitted insurers only, up to limits, and are funded by assessing the surviving carriers.
