A surplus lines quote has more parts than a personal auto bill. Knowing them keeps you from being surprised at signing or at cancellation.
Premium and minimum earned
The premium on the quote is a deposit. These policies are reported on gross receipts, month by month, and audited at the end of the year. If your receipts run higher than the estimate, the audit adds premium. Whether a lower result returns any of the deposit depends on the policy's minimum premium terms, so ask before you bind. Separately, part of the premium is minimum earned, which means the insurer keeps that part even if you cancel early. In the quote above, 25% was minimum earned, so $1,525 of the $6,100 premium was kept even if the policy was cancelled early. There was no flat cancellation, meaning you could not cancel back to the start date for a full refund.
Fully earned fees
The carrier fee and the wholesaler broker fee were fully earned. They are paid at the start and not refunded. Ask for every fee in writing before you compare two quotes.
Surplus lines tax and stamping fee
Contingent cargo and contingent auto for freight brokers are written on the surplus lines, or non-admitted, market. The state taxes those policies, and some states add a stamping fee. In the quote above the tax was about 5% in that state. The rate depends on the state, so the same premium can carry a different tax elsewhere.
How long a quote lasts
The quote was valid 30 days or until the proposed start date, whichever came first. After that it has to be re-quoted, and the number can change. If a shipper is waiting on your certificate, do not let a quote expire while you decide.
