Metric Definitions
Glossary of key metrics used in the ESL Carrier Explorer
| Metric | Definition |
|---|---|
| Gross Written Premium (GWP) | Total premium written for ESL policies in the period, before reinsurance. This is the broadest measure of a carrier's ESL business volume. Competitive use: Compare GWP across carriers to gauge relative market share and growth trajectory. |
| Earned Premium | Portion of written premium recognized for coverage actually provided during the period. Earned premium is the basis for loss ratio calculations. Competitive use: Earned premium reflects the actual risk exposure in-force during a period, smoothing out timing differences in when policies are written. |
| YoY GWP Change | (Current-year GWP / Prior-year GWP) - 1, expressed as a percentage. Measures year-over-year growth in written premium volume.Competitive use: High positive YoY signals aggressive growth or successful rate increases; sharp negative YoY may indicate market exit, book runoff, or competitive pressure. |
| Market Loss Ratio | Aggregate incurred loss ratio for the ESL market, reported annually by Oliver Wyman / Guy Carpenter in their Stop Loss Market Update. Includes incurred claims plus loss adjustment expenses (LAE) divided by earned premium. The 2024 market LR was 86.0%, up from 81.6% in 2019. Competitive use: Market LR is the key indicator of overall ESL market profitability. Rising market LR signals claims outpacing premium growth, which drives rate hardening and carrier exits. |
| DWVD Survey | Annual survey by D.W. Van Dyke & Co. (dwvd.com/stoplosssurvey), running since 2002. Captures ~45–47% of total ESL market premium (~$7B of $35.4B at YE 2023). Tracks persistency, renewal rate increases, new business volume, and actual vs. target loss ratios across Health Plans, Direct Carriers, and MGUs. Key insight: Premium persistency is a leading indicator of loss ratio outcomes. When persistency exceeds ~79%, carriers consistently miss target loss ratios (e.g., 2017: 79.2% persistency, 94.4% of participants missed target LR). Below ~77%, results improve. |
| Rank (NAIC) | Carrier ranking by direct earned premium from NAIC statutory filings, as compiled by MyHealthGuide Newsletter. Rankings reflect the relative size of each carrier's ESL book. Competitive use: Track rank changes over time to identify carriers gaining or losing market position — rank movement often leads changes visible in GWP. |
| Rank Change | Year-over-year change in NAIC ranking. Positive values indicate the carrier moved up (improved rank). Computed as prior_year_rank - current_year_rank.Competitive use: Large rank jumps (e.g., +10 or more) often signal strategic moves — new TPA partnerships, rate actions, or market entry/expansion. |
| 9-Year CAGR | Compound annual growth rate of total ESL market premium from 2016 to 2024. Reflects the overall market expansion trajectory. Competitive use: Compare individual carrier CAGR against the market CAGR to identify outperformers and underperformers over the long term. |
