A cascade, not a list of percentages
The Programme
Treaties sit in programme order and each is offered what the treaties above it did not take. A quota share cedes its share of the whole risk first; a surplus works in lines on the retention that is left; facultative sits on top of whatever is still uncovered. Excess of loss responds per risk or per catastrophe event above an attachment point, with reinstatements and the capacity still standing, and stop loss responds to the aggregate loss ratio. A treaty answers for losses inside its period even after it has expired, because cover follows the date of loss.

The programme, year by year

Quota share, surplus, excess of loss and stop loss with the lead reinsurer, period, ceded premium, recoveries and the ceded loss ratio.
A motor quota share

Thirty percent ceded on the motor classes, the broker, the programme order, the maximum cession per risk and the capacity — with the cessions, recoveries and bordereaux one click away.
The panel

Ceding commission, profit commission, brokerage and the reinsurers' written and signed lines with their financial rating. Signed lines add up to exactly 100%.
Excess of loss layers

Attachment, limit, rate on line, layer premium, reinstatements, aggregate limit, what has been eroded and the capacity remaining, layer by layer.
A surplus treaty

The retention per risk and the number of lines, the classes it covers and its place in the programme.
An excess of loss layer

Attachment, limit and rate on line, the reinstatements with their rate and basis, and the capacity still left in the year.
