Efficiency Rankings

The efficiency score (0-100) is a weighted composite of three dimensions, normalized within each sector:

• Operational gap (50%) — How far the company's key metric (combined ratio for P&C/Re, MLR for Health, ROE for Life, D/E for Brokers) deviates from sector peers, using min-max normalization.
• Trend (30%) — 3-year linear slope of the key metric and ROE. A worsening trend scores higher. Threshold: >0.5pp/year = worsening, <-0.5pp/year = improving.
• Revenue scale (20%) — Net premiums earned or revenue, linearly scaled from $0 (score 0) to $100B+ (score 100).

Requires at least 2 of 3 dimensions to produce a score. Missing dimensions are redistributed proportionally across available ones.

Expense Gap $ = (company expense ratio - sector best) / 100 x net premiums earned. Applies to P&C and Reinsurance only. Health uses admin margin pool (1 - MLR) x premiums. Brokers and Life show N/A (different business models).
