AI drafts

The AI drafts the appetite. Jordan Lee, the underwriter, approves or changes every draft. The EPL (employment practices liability) cover asked for is the policy line these drafts price.

Write 94.0% confidence that the underwriter agrees

Eligible property manager with 13 FTE, no prior EPL claims, low turnover, no planned layoffs, and required documents provided. No conflicts are reported.

Endorsements HB-104, HB-101

Schedule modification -10% 98.0% confidence. Apply -5% for an employee handbook and -5% for turnover under 15%. No other schedule factors apply.
