Understanding Captive Insurance
Should your company form a captive insurance company-or would doing so simply replace one set of costs and risks with another?
Captive insurance can give a business greater control over how it finances risk. But greater control also brings capital requirements, claims exposure, collateral demands, governance responsibilities, regulatory obligations, and federal tax questions that cannot be reduced to a sales pitch about "keeping your premiums."
Understanding Captive Insurance is a practical executive guide for CFOs, CEOs, business owners, board members, risk professionals, and advisers who want to understand how captive insurance actually works-and how to determine whether one makes economic sense.
Using Harbor Manufacturing, a fictional $125 million middle-market company, the book follows a captive feasibility analysis from the first insurance-renewal questions through a complete five-year economic model.
You'll learn how to:
Understand what a captive insurance company is-and what it is not
Distinguish captive insurance from direct self-insurance
Decide which risks may be appropriate to retain
Understand how captive premiums are actuarially developed
Separate premium, profit, cash, reserves, capital, and collateral
Evaluate claims reserves and IBNR
Understand fronting and reinsurance structures
Compare commercial insurance costs with captive economics
Model capitalization, liquidity, investment income, and present value
Understand state captive regulation and federal insurance qualification
Navigate risk shifting, risk distribution, �2, and insurance-company status
Understand �1(b) without treating it as a captive strategy
Recognize the significance of current IRS micro-captive reporting rules and court decisions
Identify warning signs in aggressive captive proposals
Conduct a disciplined captive feasibility study
Know what questions management and the board should ask before approving formation
Throughout the book, one principle remains constant:
A tax deduction is not the same thing as economic savings. A captive license is not the same thing as federal tax qualification. And the fact that a captive can be formed does not mean that it should be formed.
The Harbor Manufacturing case puts those distinctions to work. Its modeled captive produces a modest expected five-year economic advantage-but that advantage is sensitive to loss assumptions, and important legal, tax, regulatory, and governance questions remain unresolved.
The result is not an automatic recommendation to form a captive.
It is:
APPROVE DESIGN WORK - DO NOT APPROVE FORMATION YET.
That is the purpose of this book: not to sell captive insurance, but to give decision-makers the framework they need to evaluate it intelligently.
Understanding Captive Insurance - 2026 Edition is written in plain English for executives who need enough technical depth to challenge advisers, evaluate proposals, understand the economics, and make a defensible business decision-without having to become an actuary, insurance lawyer, or tax specialist.
