Chapter 12 — Further Reading

Sources grouped by the book's three citation tiers. Tier 1 is verified canonical material you can stand behind; Tier 2 is real industry practice whose exact figures shift and should be checked against current sources; Tier 3 is the constructed teaching material in this chapter.

Tier 1 — Verified canonical

• The Institutes (American Institute for CPCU), AINS and CPCU curricula — the professional body's treatment of policy provisions, deductibles, limits, sublimits, coinsurance, and policy structuring. The working vocabulary of this chapter is theirs.
• Insurance Services Office (ISO / Verisk) commercial property and general-liability forms — the standard bureau forms whose deductible options, limit structures, sublimits, and the coinsurance condition are the architecture most carriers use or adapt. (We met bureau vs. manuscript forms in Chapter 5.)
• The McCarran-Ferguson Act and state rate-and-form regulation (owned by Chapter 4) — the legal frame that makes form filing a state matter and gives the surplus-lines market its freedom of form and rate, which is why manuscript-heavy risks migrate there (§12.6).
• NAIC model laws and guidance on large-deductible insurance and collateral — the public regulatory treatment of large-deductible programs, the handling of collateral, and the allocation of recoveries in an insurer insolvency. The backbone of Case Study 1.
• State guaranty-fund / guaranty-association materials — the public record of how insolvent insurers' statutory obligations (especially workers' compensation) are backstopped, and why large-deductible collateral failures become an industry-wide concern.

Tier 2 — Attributed, specifics unverified

• Industry treatments of large-deductible and loss-sensitive workers'-compensation programs (AM Best, rating-agency and trade commentary) — the rise of these structures and their recurring failure mode are well attested; specific program sizes, deductible levels, and loss figures vary by account and era and must be checked against current sources rather than cited as fixed.
• Property-underwriting and valuation literature on coinsurance and insurance-to-value — the coinsurance mechanism and the agreed-value alternative are standard; the magnitude of the "valuation gap" driven by construction inflation is real and significant but moves with construction-cost indices, so quantify it only against current data.
• Broker and risk-management guides to deductible and retention selection — practical treatments of how sophisticated insureds choose retentions and structure programs; useful for the buyer's-eye view, with the usual caution that illustrative numbers are illustrative.

Tier 3 — Illustrative / constructed

• The Harbor Steel & Fabrication underwriting file (the 5% named-windstorm deductible, the AOP deductible, the ACV-roof endorsement, the agreed-value property basis, the 12-month business-income period-of-indemnity note, the sublimits) — constructed teaching example; realistic but not drawn from any real account.
• Case Study 1, the large-deductible WC composite (the industrial contractor, the stale letter of credit, the insolvency) — a labeled composite built from real industry patterns; all figures illustrative.
• Case Study 2, the coinsurance-penalty composite (the food-processing manufacturer, the \$10M true value vs. \$6M declared, the \$2M partial loss, the \$500K penalty) — a labeled composite; the coinsurance mechanism is real and standard, the fact pattern and numbers constructed.
• The worked structuring examples (the deductible-credit math, the limit/sublimit diagram, the coinsurance arithmetic) — illustrative round numbers chosen to make the structuring decisions legible.

If you read only one thing: open a real commercial property declarations page and a general-liability declarations page side by side, and read the deductible, the limits (per-occurrence and aggregate), the sublimits schedule, and the coinsurance condition as a designed structure rather than a list of numbers. Ask of each feature: what loss does it shed, what behavior does it engineer, and where does the insurer's money stop? That single exercise turns this chapter from theory into the way you will read every policy for the rest of your career.
