A flood program collects $4.5 billion in premium but pays $6 billion in an average loss year and borrows the gap from the Treasury. Is that program working? The answer depends on which yardstick you apply, and against what purpose.
Every government or industry program exists to fix a specific market failure. Flood and crop programs supply coverage private insurers avoid. Residual markets (FAIR plans, workers compensation assigned-risk pools, auto plans) guarantee availability to rejected applicants. Terrorism and guaranty-fund mechanisms provide a catastrophe or insolvency backstop. You cannot judge success without naming that purpose first, because a program optimized for availability will look "unprofitable" by design.
KEY: Never score a program on solvency alone. Score it against the job it was created to do. Affordability and availability are legitimate purposes even when they cost money.
Solvency asks whether the program's resources meet its obligations. Combine current premium, accumulated reserves, investment income, and any statutory backstop (Treasury borrowing authority, industry assessments) against expected annual losses including a catastrophe load.
Common mistakes
- Scoring a program on profit when its purpose is availability. A flood or residual program is meant to cover rejected risks; break-even or subsidized results can still be success. Measure against purpose, not underwriting profit.
- Counting routinely drawn borrowing authority as solvency. If the Treasury line funds an average year, the funding ratio is below 1 and the program is structurally insolvent.
- Ignoring residual-market share as a stress gauge. A share climbing from 3% to 13% flags a stressed voluntary market even when the pool itself pays claims.
Bottom line
- Judge any program on four axes: solvency, efficiency, stability, and long-run viability, always measured against its stated purpose.
- Solvency: premium plus reserves plus backstop capacity must cover expected losses; recurring Treasury borrowing signals a structural deficit, not a bad year.
- Efficiency: read the expense ratio, subsidy targeting, and control of adverse selection and moral hazard.
- Stability: low rate volatility, steady take-up, and a shrinking residual-market share signal a healthy voluntary market.
Exam shortcut
Run every program through four gates in order: solvency, efficiency, stability, long-run viability. Then ask the fifth question, "against what purpose?" A pass on all four can still fail purpose, and a fail on one still condemns the program. Compute the funding ratio excluding any backstop that is drawn every year. If resources over expected losses fall below 1 without the borrowing line, call it structurally insolvent.
