A chargeback is not a special case, and a draw is a loan
Chargebacks And Draws
A cancellation is an ordinary transaction with a negative premium, and the commission that follows it is negative through the same arithmetic. Five bases ship — pro rata, short rate, a cliff schedule by months in force, advance, and none — across nine triggers from lapse to loss of agent of record. Warnings still sixty to ninety days out are carried as commission at risk. A recoverable draw nets against every later payout until it is worked off; a non-recoverable draw is a guaranteed minimum whose shortfall is agency expense.

Why this one clawed back

The business it came from, what happened and the basis it was priced on, then the original commission, the term, the days unearned, the producer's share and exactly what comes back.
Commission at risk

Lapse, NSF and cancellation warnings that have not happened yet, with the producer charge and what is outstanding — the leading indicator of a preventable clawback.
The draw ledger

Recoverable and non-recoverable draws apart, with what was advanced, what has been recovered and what is still outstanding.
A draw, worked off

A carrier's chargeback schedule

The clawback window and the share reclaimed month by month, entered the way the carrier's contract states it.
