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 78.0% confidence that the underwriter agrees

Manufacturer is an eligible class with 15.5 FTE and no stated hard-rule or class-specific referral trigger. Two prior EPL claims are within the stated limit, but warrant a substantial schedule debit.

Endorsements HB-MA-01

Schedule modification 15% 90.0% confidence. Apply -5% for the employee handbook and +10% for each of two prior EPL claims; no other schedule factors apply.

Premium
