The two acts divide the market by product, and the division is explicit. The property and casualty model act says it "shall apply to all kinds of direct insurance" and then excludes, among other things, "life, annuity, health or disability insurance," mortgage and financial guaranty insurance, fidelity and surety bonds, title insurance, ocean marine insurance and any insurance provided or guaranteed by government. The life and health act covers policies of direct non-group life insurance, health insurance and annuities, plus certificates under group policies and certain unallocated annuity contracts. There is no overlap and no gap of the kind consumers usually worry about; there is instead a set of products, listed in each act, that neither system reaches.
The limits are model benchmarks, and the word matters. The life and health model act caps what the association can be obligated to cover, with respect to any one life regardless of how many policies are involved, at $300,000 in life insurance death benefits but not more than $100,000 in net cash surrender and withdrawal values; $250,000 in the present value of annuity benefits; and for health, $100,000 for coverages that are not disability income, long-term care or health benefit plans, $300,000 each for disability income and for long-term care, and $500,000 for health benefit plans. An overall cap limits the association to $300,000 in benefits for any one life, or $500,000 where health benefit plans are involved. The property and casualty model act runs on a different structure entirely: the full amount of a covered workers' compensation claim, not more than $10,000 per policy for the return of unearned premium, and not more than $500,000 per claimant for all other covered claims. Every one of those figures is what the NAIC recommends. States enact them with variations, and several have adopted higher or lower numbers, so the operative limit is the one in your state's statute.
The rule that bars anyone from selling you a policy on the strength of it. Section 19 of the life and health model act provides that "no person, including a member insurer, agent or affiliate of a member insurer shall make, publish, disseminate, circulate or place before the public ... any advertisement, announcement or statement, written or oral, which uses the existence of the Insurance Guaranty Association of this State for the purpose of sales, solicitation or inducement to purchase any form of insurance or other coverage covered by" the act. The same section requires a summary document with a conspicuous disclaimer, and one of its mandated statements is that the policyholder "should not rely on coverage under the Life and Health Insurance Guaranty Association when selecting an insurer." A regulator telling consumers in writing not to factor a protection into a purchase decision is unusual, and it is the sharpest available answer to anyone presenting guaranty coverage as a reason to buy from a weaker carrier. Note the scope: this is a life and health provision. The property and casualty model act contains no advertising or inducement provision at all.
How it is funded, and why that is not a fund. Both acts create the association as a nonprofit entity whose members are the licensed insurers, with membership a condition of doing business in the state. There is no pre-funded pool waiting for a failure. When one occurs, the association assesses its surviving members to raise what it needs, and those assessments are a cost of doing business that insurers may in some states recoup through premium surcharges or offset against premium taxes. This is the structural difference from federal deposit insurance, which maintains a standing fund and pays depositors directly.
Two exclusions worth knowing in advance. Neither act reaches the part of a contract where the policyholder rather than the insurer bears the investment risk, which is why the separate-account portion of a variable product sits outside the life and health system. And a contract of reinsurance is excluded "unless assumption certificates have been issued pursuant to the reinsurance policy or contract," so an arrangement between two insurers is not itself protected.
