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 88.0% confidence that the underwriter agrees

Retail is an eligible class, the account has 35 FTE, and there are no prior EPL claims or planned layoffs. High turnover warrants a schedule debit but does not trigger the restaurant-specific referral guideline.

Endorsements HB-CA-01, HB-104, HB-112

Schedule modification 5% 95.0% confidence. Apply +10% for turnover above 50% and -5% for the employee handbook; no other listed schedule factors apply.

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.

Rate table premium	$14,092
Agent premium	$14,092
Normal version premium	$14,092

Base: 28.5 FTE across rate bands		$6,990
