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.

Refer 93.0% confidence that the underwriter agrees

The broker's correction indicates 3 FTE, meeting the minimum eligibility threshold, but the signed application reports 23 full-time and 1 part-time employee. This material headcount discrepancy changes the rating band and requires referral under the guidelines. Five years of loss runs are also outstanding.

Endorsements HB-CA-01, HB-104

Schedule modification -10% 94.0% confidence. Apply -5% for the employee handbook and -5% for turnover under 15%. No other listed schedule factors apply.

Hi Alex,
