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 96.0% confidence that the underwriter agrees

Eligible retail class with 31 FTE, no prior EPL claims, no planned layoffs, and turnover below the referral threshold. Application, five-year loss runs, and current budget are provided and consistent.

Endorsements HB-104, HB-112

Schedule modification -10% 98.0% confidence. Apply -5% for the employee handbook and -5% for an HR department. Turnover of 25% does not qualify for a turnover adjustment.

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	$10,404
Agent premium	$10,404
Normal version premium	$10,404

Base: 31 FTE across rate bands		$7,340
