How RLI scores on the Insurance & Reinsurance defenses
Underwriting Discipline
Score 47
· 25% of the moat score
Underwriting discipline is the core insurance moat, and it consists mostly of the willingness to lose business.
Float Investment Quality
Score 66
· 20% of the moat score
Float is the money an insurer holds between collecting premiums and paying claims — capital it invests but does not own.
Pricing Power
Score 36
· 18% of the moat score
For an insurer, pricing power is the ability to push rate ahead of claims inflation and keep the policyholders anyway.
Capital Strength & Solvency
Score 56
· 17% of the moat score
Capital is what lets an insurer credibly promise to pay a claim that has not happened yet, and it is scrutinised by regulators and rating agencies alike.
Operational Efficiency
Score 47
· 12% of the moat score
The expense ratio — what it costs to acquire and administer a policy — is the half of the combined ratio management fully controls.
Scale & Diversification
Score 52
· 8% of the moat score
Diversification is a real economic advantage in insurance rather than a portfolio preference: risks spread across perils, geographies and lines are less likely to arrive at once, so the same capital supports more premium.

How is the moat score calculated?
Each company is scored with an industry-specific template — Insurance & Reinsurance in this case, chosen because the defenses that matter to a bank are not the ones that matter to a software company. Every defense combines several financial signals, and each signal is measured as a percentile against a peer group of 45 companies in Insurance - Property & Casualty. The defenses are then weighted to produce the overall score out of 100.
Why is RLI Corp. scored with the Insurance & Reinsurance template?
An insurer is paid before it knows what its product cost, and invests the money in the meantime. Profit therefore comes from two sources that must both work: pricing risk better than rivals, and earning a return on the float those premiums create. The Insurance template scores that pair, along with the capital that lets a company survive the year in which the losses arrive together.
Which competitive defenses are measured for RLI Corp.?
The Insurance & Reinsurance template measures 6 defenses, and RLI scores: Underwriting Discipline (47), Float Investment Quality (66), Pricing Power (36), Capital Strength & Solvency (56), Operational Efficiency (47), Scale & Diversification (52). Each is scored independently as a percentile against peers, so a company can be strong on one and weak on another — the overall score reflects how those defenses are weighted for this industry.
