17.2 Rates, Forms, Solvency, and Guaranty Associations
Key Takeaways
- Rates must be adequate, not excessive, and not unfairly discriminatory; memorize all three standards.
- Prior approval = use only after approval; file-and-use = file then use; use-and-file = use then file. Know which permits immediate use.
- Solvency tools include financial examinations, Risk-Based Capital (RBC) thresholds, and required loss/unearned-premium reserves; impaired insurers go into rehabilitation or liquidation.
- Guaranty associations pay covered claims of insolvent ADMITTED insurers, funded by assessments on other admitted insurers, subject to per-claim caps (often ~$300,000).
- Surplus lines/nonadmitted insurers are not protected by guaranty funds, and producers may not use the fund's existence as a selling point.
Rate Regulation: The Three Standards
State law requires that rates be adequate, not excessive, and not unfairly discriminatory. These three words are the most tested concept in rate regulation:
- Adequate — high enough to keep the insurer solvent and able to pay claims.
- Not excessive — not so high that the insurer earns an unreasonable profit (relative to risk and competition).
- Not unfairly discriminatory — risks of similar hazard and expense must be charged similar rates; classification must be based on actuarially sound, non-prohibited factors.
Rates are developed by advisory/rating organizations such as ISO (Insurance Services Office) and NCCI (workers compensation), which file loss costs and standardized policy forms that insurers adopt.
Rate Filing Systems
The exam expects you to distinguish how and when a rate may be used:
| System | How it works | When rate may be used |
|---|---|---|
| Prior approval | File and wait for commissioner approval | Only AFTER approval is granted |
| File-and-use | File, then use after a waiting period (or immediately) | After filing; subject to later disapproval |
| Use-and-file | Use immediately, file shortly after | Immediately; file within set days |
| Flex rating | Approval needed only outside a +/- band | Within band, file-and-use |
| Open competition (no file) | Market forces set rates | Immediately; commissioner monitors |
Trap: Under prior approval, an insurer may not use a newly filed rate until the commissioner affirmatively approves it (or the deemer period passes). Under file-and-use, filing precedes use but approval is not required up front.
Solvency Regulation
Protecting policyholders means keeping insurers financially sound. Key tools:
- Financial Examinations — periodic exams of an insurer's books, typically at least every 3-5 years.
- Risk-Based Capital (RBC) — an NAIC formula setting minimum capital relative to the risks the insurer assumes; falling below RBC thresholds triggers escalating regulatory action (Company Action, Regulatory Action, Authorized Control, Mandatory Control levels).
- Reserves — insurers must hold loss reserves (for claims incurred) and unearned premium reserves.
When an insurer becomes financially impaired, the commissioner may place it into rehabilitation (attempt to restore) or liquidation (wind down). An admitted/authorized insurer holds a certificate of authority and participates in state guaranty funds; a nonadmitted/surplus lines insurer does not.
Guaranty Associations
Every state has a property and casualty guaranty association that pays the covered claims of an insolvent admitted insurer, funded by assessments on the remaining admitted (licensed) insurers in that state.
Exam-critical limits:
- Guaranty funds protect claims of admitted insurers only. Surplus lines / nonadmitted insurers are not covered.
- Claims are subject to statutory caps (commonly $300,000 per claim in many states, though amounts vary) and a small per-claim deductible (often $100).
- Producers may not advertise or use the existence of the guaranty association to sell or solicit insurance — doing so is an unfair trade practice.
A Worked Solvency Example
Suppose an admitted insurer reports $120 million in admitted assets and $95 million in liabilities (reserves plus other obligations). Its policyholders' surplus is the difference: $120M - $95M = $25 million. Surplus is the cushion that absorbs adverse loss development and is the figure RBC compares against required capital.
If the RBC formula calls for $15 million of total adjusted capital and the insurer holds $25M, it is well above the Company Action Level. Were surplus to fall to, say, $14M (below the $15M requirement but above 70% of it), the insurer would hit the Company Action Level and must file a corrective plan. Below 50% of the requirement triggers Mandatory Control Level, where the commissioner must seize the company. Memorize the order: Company Action -> Regulatory Action -> Authorized Control -> Mandatory Control, from least to most severe.
Admitted vs. Surplus Lines — Why It Matters
An admitted (authorized) insurer files its rates and forms with the state, contributes to and is backed by the guaranty fund, and is examined for solvency. A nonadmitted (surplus lines) insurer is not licensed in the state and is used only when coverage is unavailable from the admitted market after a diligent search (the surplus lines broker documents the declinations).
Because surplus lines carriers are not state-rate-regulated, their forms and rates are more flexible — but their policyholders have no guaranty-fund protection if the carrier fails. The exam frequently pairs an unusual or hard-to-place risk (e.g., a fireworks factory) with surplus lines placement and then asks whether the guaranty fund applies. The answer is no.
A Worked Experience-Modification Example
In commercial lines (notably workers compensation), the experience modification factor (mod) adjusts a standard premium up or down based on the insured's actual loss history versus expected losses for its class.
The formula compares actual losses to expected losses. A mod of 1.00 is average. If a business has better-than-expected losses, its mod might be 0.85 (a 15% credit); worse-than-expected losses might produce 1.20 (a 20% debit).
Worked numeric: a contractor has a manual (standard) premium of $40,000 and an experience mod of 1.15. Modified premium = $40,000 x 1.15 = $46,000 — a $6,000 surcharge for poor loss experience. Conversely, a mod of 0.90 would yield $40,000 x 0.90 = $36,000, a $4,000 credit. The mod is the clearest example of rates that are not unfairly discriminatory: similar risks with different loss experience are charged differently on actuarially sound grounds.
Under a Prior Approval rate regulation system, when may an insurer begin charging a newly filed rate?
An admitted P&C insurer becomes insolvent owing covered claims. How are those claims primarily paid, and is a surplus lines insurer treated the same way?
