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 85.0% confidence that the underwriter agrees

Retail is an eligible class, the insured has 44 FTEs, and there are no prior EPL claims or planned layoffs. The high turnover does not trigger the restaurant-specific referral guideline.

Endorsements HB-104, HB-112, HB-101

Schedule modification 5% 95.0% confidence. Apply a 5% handbook credit and a 10% debit for turnover above 50%, for a net 5% debit.

Premium

Premiums come only from the fixed pricing rules, never from the AI. A schedule modification is the percent change to the base premium for the risk's features.
