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 94.0% confidence that the underwriter agrees

Eligible condo/HOA account with 18 FTE, no prior EPL claims, and no planned layoffs. No referral or decline trigger is present.

Endorsements HB-MA-01, HB-104

Schedule modification -5% 98.0% confidence. Employee handbook credit: -5%. Turnover is 16%, so no turnover adjustment applies; no HR department or prior EPL claims are reported.

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	$4,248
Agent premium	$4,248
